Summary of Risk Factors
Our business is subject to numerous risks and uncertainties that make an investment in our securities speculative or risky, any one of which could materially adversely affect our results of operations, financial condition or business. These risks include, but are not limited to, those listed below. This list is not complete, and should be read together with the section titled “Risk Factors” in this Annual Report on Form 10-K, as well as the other information in this Annual Report on Form 10-K and the other filings that we make with the U.S. Securities and Exchange Commission (the “SEC”).

Risks Related to Our Business and Our Operations

The ongoing COVID-19 pandemic could have a negative effect on our business, results of operations and financial condition.
We experienced an information technology security breach in the past and may be vulnerable to future security breaches, which could disrupt our operations and have a material adverse effect on our business, results of operation and financial condition.
Terrorist activity, or other acts of violence, including violence stemming from the current climate of political and economic uncertainty, could adversely impact our business.
Our offerings have a long sales cycle that may harm our revenue and results of operations.
Any failure of our physical infrastructure or negative impact on our ability to meet our obligations to our customers 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 condition.

The level of insurance coverage that we purchase may prove to be inadequate.
The use of high power density equipment may limit our ability to fully utilize our older IBX data centers.
If we are unable to implement our evolving organizational structure or if we are unable to recruit or retain key executives and qualified personnel, our business could be harmed.
We may not be able to compete successfully against current and future competitors.
If we cannot continue to develop, acquire, market and provide new offerings or enhancements to existing offerings that meet customer requirements and differentiate us from our competitors, our results of operations could suffer.
Our results of operations may fluctuate.
Our days sales outstanding ("DSO") may be negatively impacted by process and system upgrades and acquisitions.
3

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.
We have incurred substantial losses in the past and may incur additional losses in the future.
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.

The anticipated benefits of our joint ventures may not be fully realized or take longer to realize than expected.
Joint venture investments could expose us to risks and liabilities in connection with the formation of the new joint ventures, the operation of such joint ventures without sole decision-making authority, and our reliance on joint venture partners who may have economic and business interests that are inconsistent with our business interests.
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.
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.

Risks Related to Our Capital Needs and Capital Strategy

Our substantial debt could adversely affect our cash flows and limit our flexibility to raise additional capital.
Sales or issuances of shares of our common stock may adversely affect the market price of our common stock.

Industry Trends: Taking Digital Business to the EdgeLarge-scale global trends are driving a digital-first strategy
Digital transformation is changing where and how businesses deploy and deliver IT services to employees and is creating new digital business models for partners and customers. AtThe convergence of these global trends and the same time, macroeconomic, technology and regulatoryimpact of the ongoing COVID-19 pandemic have created additional pressure for many companies to transform. The collective influence of these trends areis driving complexity and risk that must be addressed in multiple locations for companies to effectively compete in the global digital economy. These trends include:
The Digital business transformation: Real-time interactions between people, things, locations, clouds and data require proximity and direct connections.
Urbanization: Thisservices trend is creating large, global population centers which require companies to locate digital services close to users to deliver great user experiences. These same concentrations of people provide an economy of scale which makes distributing applications, data, content and networking to serve these locations cost effective.
Cybersecurity: A cybersecurity breach is onethe continued digitizing of the back office to support digital business throughput. By 2022, 65% of global GDP will be digitalized, and most serious risks facing companies today,organizations will realize greater value by combining digitization and many ofsustainability. This trend forces the most serious breaches actually occur via a penetration of a company’s business partners’ networks. To protect against this, businesses need to distribute their security controls out to the edge where most traffic exchange is happening.
Data compliance: To meet new regulations, companies need to deploy data storage, analytics and clouds within the same jurisdiction, and then replicate this across multiple global locations.
Business ecosystems: Digital trade flows involve an increasing variety of customers, partners and employees. To enable this, companies deployfor a digital presence in close physicalinfrastructure optimized for proximity to, an industry exchange point and then connectinterconnection with, networks and clouds. This in turn enables digital development with elastic scale and has contributed to it directly. Ina 3x increase in the aggregate, these formmulticloud, multiregion adoption rate over the last two years as businesses scale the digital core.
The Digital participation trend is digitizing trade and accessing digital marketplaces (digital B2B commerce). By 2025, 75% of organization leaders will leverage digital platforms and ecosystem capabilities to adapt their value chains to new markets, industries and ecosystems. This forces the need for organizations to interconnect digital infrastructure with research communities, supply chains and marketplaces, which enables composable business models. The fifth annual Global Interconnection Index ("GXI"), a market study published by Equinix, shows that SaaS is now the largest IT spend line item as companies move to public and private SaaS alternatives. Organizations that fail to leverage cloud, SaaS or partner digital ecosystems have shown two to three times slower growth over the past two years.
The Digital proximity trend means digitizing the front office for localized and personalized delivery—to customers, employees and operations where business ecosystem. These ecosystems are expandinghappens, as well as digitizing the physical world for the physical infrastructure and operations intelligence needed to optimize commercial and environmental impact. Data shows that shifts in depthpopulation and number.

commerce centers will result in over 50% of new infrastructure being local by 2023, which will require a digital infrastructure in proximity to, and interconnecting, experiences, things (IoT) and intelligent operations.
These trends are accelerating the need for companies like Equinix who can provide a secure, compliant and responsiveagile global business platform that enables theleverages digital interconnection—or private interconnection of people, locations, clouds, data and things in multiple locations exchange—to deliver real-time interactions and data exchange around the world.
As part of their digital transformation, businesses in most industries are shifting their centralized IT infrastructures to the edge to bring digital services closer to users for better performance, which has become a significant driver of digital business value. To realize the full potential of the edge, IT organizations require greater interconnection bandwidth. Interconnection bandwidth is defined as the total capacity provisioned to privately and directly exchangedexchange traffic, with a diverse set of partners and providers, at distributed IT exchange points inside carrier-neutral colocation data centers. Private interconnection capacity between businesses, as reported in the third annual Global Interconnection Index ("GXI"), a market study published by Equinix,GXI, is anticipated to grow at a compound annual growth rate of 44% by 51% between 2018 and 2022,2024, reaching 13,300+21,485+ terabits per second which is double the projected peak of global internet traffic and could be more than 13 times the volumedata exchanged annually.

While a large number of enterprises and service providers, such as hyperscale cloud service providers, own their own data centers, many others outsourcewe believe the industry is shifting away from single-tenant solutions to outsourcing some or all of their IT housing and interconnection requirements into third party facilities, such as those operated by Equinix.us.
Historically, thatthe outsourcing market was served by large telecommunications carriers who bundled their products and services with their colocation offerings. The data center market landscape has evolved to include private and vendor-neutral MTDC providers, hyperscale cloud providers, managed infrastructure and application hosting providers, and systems integrators. It is estimated that Equinix is one of more than 1,2002,200 companies that provide MTDC offerings around the world. The global MTDC market is highly fragmented. Each of these data center solutions providers can bundle various colocation, interconnection and network offerings and outsourced IT infrastructure solutions. We believe that this outsourcing trend has accelerated and is likely to continue to accelerate in the coming years.years, especially in light of the movement to digital business as a result of the ongoing COVID-19 pandemic.
Equinix is differentiated in this market by being able to offer customers a global platform that reaches 2627 countries and contains the industry’s largest and most active ecosystem of partners in our sites. This ecosystem creates a “network effect” which improves performance and lowers cost for our customers and is a significant source of competitive advantage for Equinix.

We are integrating a focus on diversity, inclusion and belonging ("DIB") into every aspect of how we run our business. In 2020, we embarked on a multi-year DIB strategy with governance through a DIB Council chaired by our CEO and CHRO, and in partnership with our Sustainability Program Office, that oversees our progress on environmental, social and governance ("ESG") matters. Our DIB strategy focuses on attracting, retaining and developing a diverse, global workforce; building leadership capability; and empowering our people to bring DIB to life. We are focused on creating multiple pathways to reach new talent from diverse communities. In 2021, we forged partnerships and invested in tools and systems to grow and support our inclusive hiring practices and made updates to our recruitment marketing to reach a wider candidate pool more effectively. We also embedded diversity and inclusive competencies and behaviors in our leadership profiles and added coaching tools as well as manager training on leading inclusive teams to our development program. Our Equinix Employee-led Connection Networks ("EECNs") are integral to our DIB strategy and play an important role in creating belonging and advocating for the needs and goals of communities with common identities, cultures or backgrounds. Each of our nine EECNs represents an identity/community that has faced historical discrimination or shares unique challenges. We recognize that creating the best workplace and culture we can requires a global effort with localized awareness and approaches. Late in 2020, we launched WeAreEquinix employee teams empowered to create, localize and promote purpose, inclusion and belonging for their locations across the world. Through live and virtual events, campaigns, and collaboration with the business, these volunteer leaders bring local opportunities to engage in the following areas: Wellbeing, Green and Sustainability, Community Impact, Fun and Creativity, Diversity, Inclusion and Belonging, and Employee Networks. We currently have WeAreEquinix teams in 15 locations.
In 2021, we launched our “I Matter” initiative aim to empower everyenable employees to voluntarily self-identify by adding their data across dimensions of diversity, including race/ethnicity, sexual orientation, gender identity, and disability in accordance with country regulations so that we may better understand the global employee experience.
Equinix representatives have joined the G100 Talent Consortium Task Force on Racial Inequity in Business to consider core inequity issues, including anti-racism, bias, and hiring and promotability practices, in order to develop tangible best practices that companies can use as guide rails to increase representation and career mobility for black, indigenous and people of color ("BIPOC") employees. In 2021, we hosted a Days of Understanding event as part of an initiative of CEO ACT!ON, a pledge Equinix has taken along with hundreds of other companies to embrace difference in our company.  For example,organizations, educate our Women Leaders Networkpeople and build more inclusive cultures inside and outside of over 1,900our workplaces. As part of this partnership, three Equinix employees is driving visibilityjoined ACT!ON’s inaugural two-year fellowship program focused on identifying, developing, and promoting scalable and sustainable policies and corporate best practices that address systemic racism and social injustice to improve societal wellbeing. Equinix also joined the Alliance for Global Inclusion, a coalition of womenglobal organizations working together to bring inclusivity and full equity to the workplace. Finally, in 2021 Equinix partnered with McKinsey to provide leadership development to our workforce and encouragingBlack/African American leaders through the emergence of new leaders worldwide.  Also, our EquinixBlack Leadership Academy.
Our Community Impact program continues to grow, enablingpromotes connection and belonging, and enables employees to give back, to their communities with the support of Equinix, volunteering nearly 14,000 hours to local causes.the communities in which we work and live. In 2021, our employees volunteered at approximately 2,230 nonprofits worldwide.
a5culture.jpgWe believe our commitment to the highest standards of honesty, integrity and ethical behavior differentiates our business as much as our technology. We promote these high standards through a number of policies including the Equinix Code of Business Conduct. All employees are required to complete trainings on ethics and the company’s anti-bribery and corruption policies. In addition, we maintain a confidential ethics helpline where employees are encouraged to speak up if they have any questions or concerns that our code is being violated. We have a zero-tolerance, non-retaliation policy that protects our employees when they speak up.
In a year again disrupted by the unprecedented global pandemic caused by COVID-19, we continued a number of precautionary measures in line with our business continuity and pandemic plans to minimize the risk of operational impacts and to protect the health and safety of employees, customers, partners and our communities. During the pandemic, we have focused on a careful, safe and responsible opening of our offices based on guidance from health experts and other leaders from around the world. As we look forward to the future of work, and more importantly amplifying Equinix’s vibrant culture, we are providing flexible, hybrid work opportunities in many roles, enhanced collaboration technologies for everyone, and activity-based workspaces at home or onsite. We recognize that the new normal will require changing behaviors. As such, we are providing learning opportunities and best practices to ensure our meetings, events and work sessions are inclusive and equitable for virtual and in-person participation. Employee well-being has been central to these efforts, driven globally through offerings such as health programs, ergonomic support, technology reimbursements, and wellness days.

Sustainability
At Equinix, our Future First sustainability strategy rallies our people and partners to envision a better future and then do what it takes to make it happen. As the world’s digital infrastructure leader, we have the responsibility to harness the power of technology to create a more accessible, equitable and sustainable future. The ESG initiatives comprising our Future First strategy focus on the material issues that have the greatest impact on our stakeholders and our business. We continue to progress on our sustainability goals and look to build a business and world that reflects our purpose to bring the world together on our platform to create the innovations that will enrich our work, life and planet. We document our ESG progress in our Annual Report as well as in the annual Corporate Sustainability Report located on our sustainability website: sustainability.equinix.com.
In 2021, we committed to becoming climate neutral across our global operations by 2030 and set a validated science-based target (“SBT”) for emissions reduction across our global operations and supply chain. Our climate commitments are a critical step to ensure that we continue to advance investments and innovations to reduce greenhouse gas ("GHG") emissions and keep global warming to 1.5 degrees Celsius in alignment with the Paris Climate Agreement.
As a part of our Future First sustainability strategy, we published an Environmental Sustainability and Global Climate Change Policy in 2021 to detail our approach and practices related to the environment, climate change, resource efficiency and reporting. In alignment with our strategy and policy, we are also evaluating our material climate change risks and opportunities based on the recommendations of the Task Force on Climate Related Financial Disclosures (“TCFD”). We are continuing our work to embed climate change risk management into our business where relevant.
Environmental Performance
Equinix ownswas the first data center company to commit to a long-term goal of 100% renewable energy across our global portfolio. We use local renewable energy sources where possible, seek new or recently built renewable sources and maintains intellectual propertyadvocate for favorable renewable energy policies. In the U.S., we purchase more than 2.3 million megawatt-hours (MWh) of green power annually from a portfolio of renewable energy projects, including 225 MW of wind power under long-term virtual power purchase agreements (VPPAs) located in Texas and Oklahoma. In 2020, over 90% of our global electricity consumption, and 100% of U.S. electricity consumption, was covered by renewable energy sources.
We are committed to transparently measuring and reporting our global carbon footprint across direct (Scope 1), indirect energy (Scope 2) and indirect value chain (Scope 3) emissions. Since 2015, we have achieved a 50% reduction in GHG emissions on an absolute basis (Scope 1 and Scope 2 market-based metric tons of carbon dioxide-equivalent (mtCO2e)), even as the company doubled its footprint in both energy consumption and number of sites. In 2021, CDP, a global non-governmental organization dedicated to helping investors and companies measure and manage their climate risks, recognized our commitments, actions and progress on climate change.

We received an 'A-' CDP leadership score for climate action and annual disclosures within the CDP Climate Change survey.
We are leveraging technology and innovation to encourage commercialization of solutions that will enable the “Data Center of the Future”. To support our ongoing sustainability initiatives and commitment to innovation, we issued green bonds totaling $1.4 billion in 2020 and an additional $2.3 billion in 2021. Our Green Finance Framework aligns our sustainability commitments with our long-term financing needs and highlights our pipeline of green projects and data center innovations. In 2021, we allocated $2.9 billion in net proceeds to finance or refinance, in whole or in part, ongoing and new projects in categories of green buildings, renewable energy and energy efficiency.
We are committed to advancing environmental progress across other areas of our operations. While energy usage, specifically electricity, is our largest environmental impact, to address the growing importance of water within our operations, we launched a Sustainable Water Management Program in 2021. We consider the consumption of water in the formdesign and operation of trademarks, patents, application programming interfaces,our facilities and are developing a coordinated global approach to water measurement and management. Through our efforts to establish the European Climate-Neutral Data Centre Operator Pact in 2021, Equinix and the EU data center industry have also committed to advancing initiatives beyond renewable energy and energy efficiency, including water efficiency, waste reduction, and circular economy principles.
Sustainability Accounting Standards Board ("SASB") Disclosures
SASB published the Sustainability Accounting Standard ("Standard") for the Real Estate Industry in October 2018. We have aligned our SASB disclosures with the Real Estate Standard to enhance corporate disclosure around ESG performance. In our comprehensive disclosures in our annual Corporate Sustainability Report we also document our progress against metrics as outlined in other frameworks such as the Global Reporting Initiative ("GRI"), UN Sustainable Development Goals ("SDGs") and TCFD. The following tables detail our energy metrics, aligned with the SASB Real Estate Standard. We intend to expand our reporting around the Real Estate Standard in the coming years.
The following metrics represent our colocation facilities performance in the calendar years specified. Energy, renewable energy and GHG emissions are independently assured to ISO 14064-3:2006 Standards for the quantification and reporting of GHG emissions (Scope 1, 2 and 3). Calendar year data for 2021 will become available in Q2 2022 and published in our annual Corporate Sustainability Report located on our sustainability website.

Information contained on or accessible through our website is not part of this Annual Report on Form 10-K.

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:
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, we have completed numerous acquisitions, including most recently that of Axtel S.A.B. de C.V. in Mexico on January 8, 2020. On January 14, 2020, we also announced an agreement to acquire Packet Host, Inc., a bare metal automation company. We cannot assure that we will consummate the acquisition of Packet or any future acquisition. We expect to make additional acquisitions in the future which may include (i) acquisitions of businesses, products, solutions or technologies that we believe to be complementary, (ii) acquisitions of new IBX data centers or real estate investment trust 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)federal income tax purposes ("REIT"), 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:
including the possible disruption of our ongoing business and diversion of management'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 possibilityrisk 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 a transaction or selling stock in 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 in 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" of a new or different IBX data center;
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 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;
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 marginsqualification as we absorb these additional expenses. Therea REIT which could expose us to substantial corporate income tax and have a materially adverse effect on our business, financial condition, and results of operations.

In September, we announced that we extended Platform Equinix into the strategic Indian market, following the completion of the acquisition of the India operations of GPX Global Systems, Inc. ("GPX India"). The $170.5 million transaction includes a fiber-connected campus in Mumbai with two data centers. The expansion into India is intended to unlock opportunities for Indian businesses expanding internationally and for multinational corporations pursuing growth and innovation in the Indian market.
In June, we entered into aan agreement to form another joint venture in the form of a limited liability partnership with GIC, Singapore'sSingapore’s sovereign wealth fund, to develop and operate xScale™additional xScaleTM data centers in Europe. We sold our London 10Europe and Paris 8 the Americas (the “EMEA 2 Joint Venture”). In October, we also entered into an agreement to form a joint venture in the form of a limited liability partnership with PGIM Real Estate ("PGIM"), to develop and operate xScaledata centers in Asia-Pacific (the "Asia-Pacific 2 Joint Venture"). Combined with our existing xScale joint ventures in Europe, Asia-Pacific and certain construction developmentthe Americas, these joint ventures will bring our global xScale data center portfolio to more than $7.5 billion across 34 facilities when completed and leasesfully constructed.
In June, we opened our first data center in LondonBordeaux, France ("BX1"). With direct fiber links to Equinix's International Business Exchange™ (IBX®) sites in Paris, this new facility will provide global businesses and Frankfurtlocal authorities located in the region with the ability to connect directly and securely to the Joint Venture.world's digital economy, via comprehensive digital ecosystems. Increasing connectivity opportunities further, BX1 will provide a landing hub for the new submarine cable, AMITIE, which will link France to the United States and Great Britain, creating a new European gateway for data traffic between the United States and Europe.

In March, we announced that Equinix Metal™ had significantly advanced its global scale, features and ability to enable as a service consumption of the full value of Platform Equinix®. With these new and enhanced capabilities, Equinix Metal customers can consume interconnected infrastructure with the control of physical hardware and the low overhead and developer experience of the cloud, helping them move faster in today's competitive environment. This announcement also included the expanded availability of Equinix Metal in 18 global metros, the addition of new networking features to support hybrid multicloud architectures, the certification of new software integrations on Equinix Metal and the launch of a managed appliance as a service solution.
Industry Trends: Large-scale global trends are driving a digital-first strategy
Digital transformation is changing where and how businesses deploy and deliver IT services to employees and is creating new digital business models for partners and customers. The convergence of these global trends and the impact of the ongoing COVID-19 pandemic have created additional pressure for many companies to transform. The collective influence of these trends is driving complexity and risk that must be addressed in multiple locations for companies to effectively compete in the global digital economy. These trends include:
The Digital services trend is the continued digitizing of the back office to support digital business throughput. By 2022, 65% of global GDP will be digitalized, and most organizations will realize greater value by combining digitization and sustainability. This trend forces the need for a digital infrastructure optimized for proximity to, and interconnection with, networks and clouds. This in turn enables digital development with elastic scale and has contributed to a 3x increase in the multicloud, multiregion adoption rate over the last two years as businesses scale the digital core.
The Digital participation trend is digitizing trade and accessing digital marketplaces (digital B2B commerce). By 2025, 75% of organization leaders will leverage digital platforms and ecosystem capabilities to adapt their value chains to new markets, industries and ecosystems. This forces the need for organizations to interconnect digital infrastructure with research communities, supply chains and marketplaces, which enables composable business models. The fifth annual Global Interconnection Index ("GXI"), a market study published by Equinix, shows that SaaS is now the largest IT spend line item as companies move to public and private SaaS alternatives. Organizations that fail to leverage cloud, SaaS or partner digital ecosystems have shown two to three times slower growth over the past two years.
The Digital proximity trend means digitizing the front office for localized and personalized delivery—to customers, employees and operations where business happens, as well as digitizing the physical world for the physical infrastructure and operations intelligence needed to optimize commercial and environmental impact. Data shows that shifts in population and commerce centers will result in over 50% of new infrastructure being local by 2023, which will require a digital infrastructure in proximity to, and interconnecting, experiences, things (IoT) and intelligent operations.
These trends are accelerating the need for companies like Equinix who can provide a secure, agile global business platform that leverages digital interconnection—or private data exchange—to deliver real-time interactions around the world.
As part of their digital transformation, businesses in most industries are shifting their centralized IT infrastructures to the edge to bring digital services closer to users for better performance, which has become a significant driver of digital business value. To realize the full potential of the edge, IT organizations require greater interconnection bandwidth. Interconnection bandwidth is defined as the total capacity provisioned to privately and directly exchange traffic, with a diverse set of partners and providers, at distributed IT exchange points inside carrier-neutral colocation data centers. Private interconnection capacity between businesses, as reported in the GXI, is anticipated to grow at a compound annual growth rate of 44% by 2024, reaching 21,485+ terabits per second of data exchanged annually.

Using Equinix IBX data center business. A failuretechnicians, Smart Hands allows customers to successfully partner, or a failure to realize our expectations for the Joint Venture, could materially impact ourmanage and outsource their business financial condition and results of operations.
Joint venture investments, such as our Joint Venture with GIC, could expose us to risks and liabilities in connection with the formation of the new joint ventures, the operation of such joint ventures without sole decision-making authority, and our reliance on joint venture partners who may have economic and business interests that are inconsistent with our business interests.

In addition to our Joint Venture with GIC, we may co-invest with other third parties through partnerships, joint ventures or other entities in the future. These joint ventures could result in our acquisition of non-controlling interests in or shared responsibility for managing the affairs of a property or portfolio of properties, partnership, joint venture or other entity. We may be subject to additional risks, including:
we may not have the right to exercise sole decision-making authority regarding the properties, partnership, joint venture or other entity;
if our partners become bankrupt or fail to fund their share of required capital contributions, we may choose to or be required to contribute such capital;
our partners may have economic, tax or other business interests or goals which are inconsistent with our business interests or goals, and may be in a position to take actions contrary to our policies or objectives;
our joint venture partners may take actions that are not within our control, which could require us to dispose of the joint venture asset, transfer it to a taxable REIT subsidiary ("TRS") in order for Equinix to maintain its qualification for taxation as a REIT, or purchase the partner's interests or assets at an above-market price;
our joint venture partners may take actions unrelated to our business agreement but which reflect poorly on Equinix because of our joint venture;
disputes between us and our partners may result in litigation or arbitration that would increase our expenses and prevent our management from focusing their time and effort on our day-to-day business; and
we may in certain circumstances be liable for the actions of our third-party partners or guarantee all or a portion of the joint venture's liabilities, which may require the company to pay an amount greater than its investment in the joint venture.
Each of these factors may result in returns on these investments being less than we expect or in losses, and our financial and operating results may be adversely affected.
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, 2019, our total indebtedness (gross of debt issuance cost, debt discount, and debt premium) was approximately $11.9 billion, our stockholders' equity was $8.8 billion and our cash, cash equivalents, and investments totaled $1.9 billion. In addition, as of December 31, 2019, we had approximately $1.9 billion of additional liquidity available to us from our $2.0 billion revolving credit facility. In addition to our substantial debt, we lease many of our IBX data centers and certain equipment under lease agreements, some of which are accounted for as operating leases. As of December 31, 2019, we recorded operating lease liabilities of $1.5 billion, which represents our obligation to make lease payments under those lease arrangements.
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, or of a downgrade to our current rating;
make it more difficult for us to satisfy our obligations under our various debt instruments;
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;
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.
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.
The phase out of the London Interbank Offered Rate (“LIBOR”), and uncertainty as to its replacement, may adversely affect our business.
On July 27, 2017, the United Kingdom Financial Conduct Authority, which regulates LIBOR, announced that it intends to stop persuading or compelling banks to submit rates for the calibration of LIBOR after 2021 after which time it can no longer guarantee its availability. Although alternative reference rates have been proposed, it is unknown at this point which of these alternative reference rates will attain market acceptance as replacements for LIBOR.
Certain term loan borrowings under our Senior Credit Facility bear interest at rates that are calculated based on LIBOR. In addition, certain of our agreements, including financing, customer, vendor, leasing, intercompany, derivative and joint venture agreements, also make reference to LIBOR. To prepare for the phase out of LIBOR, we may need to renegotiate the Senior Credit Facility and other agreements and may not be able to do so on terms that are favorable to us. It is also currently unknown what impact any contract modification will have on our financial statements. Further, the financial markets may be disrupted as a result of the phase out of LIBOR if banks fail to execute a smooth transition tomaximize uptime whether from within an alternate rate.
Disruption in the financial markets or the inability to renegotiate our agreements to remove and replace LIBOR on favorable terms, or a negative impact from any contract modifications, could have an adverse effect on our business, financial position, and operating results.
Adverse global economic conditions and credit market uncertainty could adversely impact our business and financial condition.
Adverse global economic conditions 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. Customers and vendors filing for bankruptcy can also lead to costly and time-intensive actions with adverse effects. The uncertain economic environment could also have an impact on our foreign exchange forward contracts if our 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, 2019, 2018 and 2017, we recognized approximately 58%, 55% and 55%, respectively, of our revenues outside the U.S. We currently operate outside of the U.S. in Canada, Brazil, Colombia, Mexico, 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 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, the political unrest in Hong Kong, and the trade war between the U.S. and China, 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, Indonesia, Mexico, Oman, 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.

Our business may be adversely affected by the recent coronavirus outbreak.
In December 2019, a novel strain of coronavirus, referred to as 2019-nCoV, Covid-19 Coronavirus Epidemic, or Covid-19, was reported to have surfaced in Wuhan, China. Covid-19 has since spread to other regions in China and other countries, including jurisdictions in which we operate. We continue to monitor our operations and government recommendations and have made some modifications to our operations because of Covid-19. For example, we have implemented enhanced health and safety precautions in certain of our IBXs to reduce the risk of exposure and have requested that non-IBX datacenter employees in certain jurisdictions work from home and refrain from travel. The outbreak and any additional preventative or protective actions that we may take in response to this Covid-19 or any other global health threat or pandemic may result in business and/or operational disruption. Our customers’ businesses could be disrupted, and our revenues could be negatively affected. Additionally, global economic disrupters like the Covid-19 could negatively impact our supply chain and cause delays in the construction of our IBX datacenters which rely on materials, products and manufacturing from China. It may not be possible to find replacement products or supplies and ongoing delays could affect our business and growth. While it is too early to tell whether Covid-19 will have a material effect on our business over time, we are experiencing delays from certain vendors and suppliers who have been affected more directly by Covid-19 in China. The extent to which Covid-19 impacts our results will depend on many factors and future developments, including new information about Covid-19 and any new government regulations which may emerge to contain the virus, among others.
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 2019, we had $300.0 million of shares available for sale under our ATM Program. We may also seek authorization to sell additional shares of common stock under the ATM Program which could lead to additional dilution for our stockholders. Please see Note 12 of the Notes to the 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, 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;
changes in U.S. or foreign tax laws;
changes in management or key personnel;
developments in our relationships with customers;
announcements by our customers or competitors;
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'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 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 risks, refer to our discussion of foreign currency risk in "Quantitative and Qualitative Disclosures About Market 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 and other 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 and other taxes. 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 changes to the tax laws and interpretations thereof. For example, we are currently undergoing audits and appealing the tentative assessments in a number of

jurisdictions where we operate. The final results of these audits and the outcome of the appeals are uncertain and may not be resolved in our favor. Further, the nature and timing of any future changes to each jurisdiction'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 revenue and operating results.
A customer'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. Asor from a result, we have a long sales cycle. Furthermore, we may devote significant time and resources to pursuing a particular sale or customer that does not result in 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.remote location.
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 negative impact on our ability to provide our services, 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 providingEquinix Infrastructure Services(EIS) provides customers with highly reliable solutions. We must safehouse our customers' infrastructurea one-stop shop for data center installation, migration and equipment located inprocurement. With proven practices developed over many years of successfully building, migrating and optimizing our IBXcustomers’ data centerscenter needs, EIS services lend expertise to address larger, more complex data center jobs including installation and ensure our IBX data centers and non-IBX offices

remain operational at all times. 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 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 buildings 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.
Problems at one or more of our IBX data centers or corporate offices, whether or not within our control, could result in service interruptions or significant infrastructure or equipment damage. These could result from numerous factors, including:
human error;
equipment failure;
physical, electronic and cyber security breaches;
fire, earthquake, hurricane, flood, tornado and other natural disasters;
extreme temperatures;
water damage;
fiber cuts;
power loss;
terrorist acts;
sabotage and vandalism;
global pandemics or health emergencies, such as the coronavirus; and
failure of business partners who provide our resale products.
We have service level commitment obligations to certain customers. As a result, service interruptions or significant equipment damage in our IBX data centers could result in difficulty maintaining service level commitments to these customers and potential claims related to such failures. Because our IBX data centers are critical to many of our 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 internet 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 and processes.  Difficulties from or disruptions to these efforts may interrupt our normal operations and adversely affect our business and operating results.
We have been investing heavily in 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 we operate in.  These continuing investments include: 1) ongoing improvements to the customer experience from initial quote to customer billing and our revenue recognition process; 2) integration of recently-acquired operations onto our various information technology systems; and 3) implementation of new toolsbuilds, planned migrations, structured cabling, labelling and technologies to either further streamlinedocumentation, procurement recommendations and automate processes,coordination, and secure de-installation.
Competition
While a large number of enterprises and service providers, such as our procurement system, or to support our compliance with evolving U.S. GAAP, such as the new revenue accounting, derivatives and hedging and leasing standards.  As a result of our continued work on these projects, we may experience difficulties with our systems, management distraction and significant business disruptions. For 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 difficulties or disruptions 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 may 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. These 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;
delays related to permitting from public agencies and utility companies; and
delays in site readiness leading to our failure to meet commitments made to customers planning to expand into a new build.
Construction projects are dependent on permitting from public agencies and utility companies. We are currently experiencing permitting delays in Amsterdam due to the temporary halt on construction of data centers in the municipality due to pressure on power infrastructure and special planning. While we don't expect any negative impact for our business in Amsterdam, these types of delays related to permitting from public agencies and utility companies could occur in other markets and have an adverse effect on our growth.

Additionally, all construction related 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 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 IBXhyperscale cloud service providers, own their own data centers, we may provide interconnectionbelieve the industry is shifting away from single-tenant 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, permits or leases for the removal or cleanup of such substances or materials, the cost of which could be substantial.
We purchase significant amounts of electricity from generating facilities and utility companies that are subject to environmental laws, regulations and permit requirements. These environmental requirements are subject to material change, which could result in increases in our electricity suppliers' compliance costs that may be passed through to us. Regulations promulgated by the U.S. EPA could limit air emissions from coal-fired power plants, restrict discharges of cooling water, and otherwise impose new operational restraints on conventional power plants that could increase costs of electricity. Regulatory programs intended to promote increased generation of electricity from renewable sources may also increase our costs of procuring 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 environmental regulations do not normally impose material costs upon our operations, unexpected events, equipment malfunctions, human error and changes in law or regulations, among other factors, can lead to additional capital requirements, limitations upon our operations and unexpected increased costs.
Regulation of greenhouse gas ("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. There has been interest in the U.S. Congress in addressing climate change expressed by a number of bills introduced in the current Congressional Session. Federal legislative proposals to address climate change include measures ranging from "carbon taxes," to tax credits, to federally imposed limitations on GHG emissions. The course of future legislation and regulation remains difficult to predict and the potential increased costs associated with GHG regulation or taxes cannot be estimated at this time.
State regulations also have the potential to increase our costs of obtaining electricity. Certain states, like California, 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 conventional power plants by imposing regulatory caps and by auctioning the rights to emission 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 northeastern states adopted a multi-state program for limiting 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 have a material adverse effect on electricity costs in the future.
Aside from regulatory requirements, we have separately undertaken efforts to procure energy from renewable energy projects in order to support new renewables development. The costs of procuring such energy may exceed the costs of procuring electricity from existing sources, such as existing utilities or electric service provided through conventional grids. These efforts to support and enhance renewable electricity generation may increase our costs of electricity above those that would be incurred through procurement of conventional electricity from existing sources.
Our business may be adversely affected by climate change and responses to it.
Severe weather events, such as droughts, heat waves, fires, hurricanes, and flooding, pose a threat to our data centers and our customers' IT infrastructure through physical damage to facilities or equipment, power supply disruption, and long-term effects on the cost of electricity. The frequency and intensity of severe weather events are reportedly increasing locally and regionally as part of broader climate changes. Global weather pattern changes may also pose long-term risks of physical impacts to our business.
We maintain disaster recovery and business continuity plans that would be implemented in the event of severe weather events that interrupt our business or affect our customers' IT infrastructure. While these plans are designed to allow us to recover from natural disasters or other events that can interrupt our business, we cannot be certain that our plans will protect us or our customers from all such disasters or events. Failure to prevent impact to customers from such events could adversely affect our business.
We face pressures from our customers and stockholders, who are increasingly focused on climate change, to prioritize sustainable energy practices, reduce our carbon footprint and promote sustainability. To address these concerns, we pursue opportunities to improve energy efficiency and implement energy-saving retrofits. In addition, we have established a long-term goal of using 100% clean and renewable energy. As a result of these and other initiatives, we have made progress towards reducing our carbon footprint. It is possible, however, that our customers and investors might not be satisfied with our sustainability efforts or the speed of their adoption. If we do not meet our customers' or stockholders' expectations, our business and/or our share price could be harmed.
Concern about climate change in various jurisdictions may result in more stringent laws and regulatory requirements regarding emissions of carbon dioxide or other GHGs. As described above under "RISK FACTORS - Environmental regulations may impose upon us new or unexpected costs," restrictions on carbon dioxide or other GHG emissions could result in significant increases in operating or capital costs, including higher energy costs generally, and increased costs from carbon taxes, emission cap and trade programs and renewable portfolio standards that are imposed upon our electricity suppliers. These higher energy costs, and the cost of complying across our global platform, or of failing to comply with these and other climate change regulations, may have an adverse effect on our business and our results of operations.
Our business could be harmed by prolonged power outages, shortages or capacity constraints.
Our IBX data centers are affected by problems accessing electricity sources, such as planned or unplanned power outages and limitations on transmission or distribution. Unplanned power outages, including, but not limited to those relating to large storms, earthquakes, fires, tsunamis, cyberattacks and planned power outages by public utilities such as those related to Pacific Gas and Electric Company's ("PG&E") planned outages in California to minimize fire risks, could harm our customers and our business. Our international operations are sometimes located outside of developed, reliable electricity markets, where we are exposed to some insecurity in supply associated with technical and regulatory problems, as well as transmission constraints. Some of our IBX data centers are located in leased buildings where, depending upon the lease requirements and number of tenants involved, we may or may not controloutsourcing some or all of their IT housing and interconnection requirements to third party facilities, such as those operated by us.
Historically, the infrastructure including generatorsoutsourcing market was served by large telecommunications carriers who bundled their products 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. We attempt to limit our exposure to system downtime by using backup generators and alternative power supplies, but these measures may not always prevent downtime, which can adversely affect customer experience and revenues.
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 increasing per unit of equipment. 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 fromservices with their installed circuits, which can result in growth in the aggregate power consumption of our facilities beyond our originally planning and expectations. This means that limitations on the capacity of our electrical

delivery systems and equipment could limit customer utilization of our IBX data centers. These limitations 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.
Each new facility requires access to significant quantities of electricity. Limitations on generation, transmission and distribution may limit our ability to obtain 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.
colocation offerings. The security of our electricity supplies in California could be adversely affected by the actions of the court in the bankruptcy proceeding (the "Bankruptcy Court") filed on January 29, 2019, of PG&E, the public utility that serves the area in which some of our facilities are located. PG&E announced that it filed for bankruptcy to facilitate the resolution of liabilities in connection with the 2017 and 2018 Northern California wildfires. On January 31, 2020, PG&E filed an amended proposed chapter 11 plan of reorganization (the “Plan”). If confirmed, the Plan will provide for the assumption (i.e., continuation) of all executory contracts not otherwise rejected (i.e., breached) during the pendency of the bankruptcy case, including high-priced power purchase agreements and other agreements under which PG&E procures electricity for distribution to customers like us. Until the Plan is confirmed by the Bankruptcy Court and becomes effective, there are no assurances that any or all executory contracts will be assumed. It is still possible that, during its bankruptcy, PG&E could seek permission from the Bankruptcy Court to reject certain burdensome executory contracts. 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. The Bankruptcy Court disagreed with FERC, holding instead that FERC does not have concurrent jurisdiction, or any jurisdiction, over the determination of whether any rejection of a power purchase agreement should be authorized. FERC’s ruling and the Bankruptcy Court’s decision are on direct appeal to the United States Court of Appeals for the Ninth Circuit where they remain under review. If PG&E seeks and is ultimately 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 availability and reliability of electricity supplied to our facilities and relying on a larger percentage of electricity generated by fossil fuels, any of which could reduce supplies of electricity available to our operations or increase our costs of electricity.
Any power outages, shortages or capacity constraints may have an adverse effect on our business and our results of operations.
If we are unable to implement our evolving organizational structure or 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, we undertook a review of our organizational architecture and have made, and will continue to make, changes as a result of that review. There can be no assurances that the changes won't result in attrition, that the significant amount of management and other employees' time and focus to implement the changes won't divert attention from operating and growing the business, or that any changes will result in increased organizational effectiveness. We must also continue to identify, hire, train and retain key personnel who maintain relationships with our customers and who can provide the technical, strategic and marketing skills required for our 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 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.landscape has evolved to include private and vendor-neutral MTDC providers, hyperscale cloud providers, managed infrastructure and application hosting providers, and systems integrators. It is estimated that Equinix is one of more than 1,2002,200 companies that provide theseMTDC offerings around the world. Equinix competes withThe global MTDC market is highly fragmented. Each of these firms which vary in terms of their data center offerings.solutions providers can bundle various colocation, interconnection and network offerings and outsourced IT infrastructure solutions. We mustbelieve that this outsourcing trend has accelerated and is likely to continue to evolve our product strategy and beaccelerate in the coming years, especially in light of the movement to digital business as a result of the ongoing COVID-19 pandemic.
Equinix is differentiated in this market by being able to differentiate our IBX data centersoffer customers a global platform that reaches 27 countries and product offerings from thosecontains the industry’s largest and most active ecosystem of our competitors.
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 spacepartners in our IBX data centers. Similarly, with growing acceptance of cloud-based technologies, we 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 flowssites. This ecosystem creates a “network effect” which improves performance and results of operations.
If we cannot continue to develop, acquire, market and provide new offerings or enhancements to existing offerings that meet customer requirements and differentiate us from our customers, our operating results could suffer.
As our customers evolve their IT strategies, we must remain flexible and evolve along with new technologies and industry and market shifts. Ineffective planning and execution in our cloud and product development strategies may cause difficulty in sustaining our competitive advantages.
The process of developing and acquiring new offerings and enhancing existing offerings is complex. If we fail to anticipate customers’ evolving needs and expectations or do not adapt to technological and IT trends, our results of operations could suffer. In order to adapt effectively, we sometimes must make long-term investments, develop, acquire or obtain certain intellectual property and commit significant resources before knowing whether our predictions will accurately reflect customer demandlowers cost for the new offerings. If we misjudge customer needs in the future, our new offerings may not succeed, and our revenues and earnings may be harmed. Additionally, any delay in the development, acquisition, marketing or launch of a new offering could result in customer dissatisfaction or attrition. If we cannot continue adapting our products, or if our competitors can adapt their products more quickly than us, our business could be harmed.
We recently announced our Joint Venture with GIC and are also in discussions with a targeted set of hyperscale customers to develop capacity to serve their larger footprint needs by leveraging existing capacity and dedicated hyperscale builds. We have announced our intention to seek additional joint venture partners for certain of our hyperscale builds. There can be no assurances that our joint ventures will be successful or that we find additional partners or that we are able to successfully meet the needs of these customers.
We also recently announced an agreement to acquire Packet Host, Inc., a bare metal automation company which would facilitate a new product offering for Equinix. While we believe this new product offering will be desirable to our customers and will complementis a significant source of competitive advantage for Equinix.
Customers
Our customers include telecommunications carriers, mobile and other network services providers, cloud and IT services providers, digital media and content providers, financial services companies, and global enterprise ecosystems in various industries. We provide each company access to a choice of business partners and solutions based on their colocation, interconnection and managed IT service needs, and delivered 99.999% operational uptime across our other offerings on Platform Equinix, we cannot guarantee the success of this product or any other new product offering. Our company has not historically offered hardware solutions, and this would be a new market area for us which can bring challenges and could harm our business if not executed in the time or manner that we expect.
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 IBXglobal 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 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'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, 2019, 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 recently acquired businesses, 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 solutions at our IBX data centers;
changes in general economic conditions, such as an economic downturn, or specific market conditions in the telecommunications and internet 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's operations;
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;
additions and changes in product offerings and our ability to ramp up and integrate new products 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 electricity;
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 GAAP as periodically released by the Financial Accounting Standards Board ("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") may be negatively impacted by process and system upgrades and acquisitions.
Our DSO may be negatively impacted by ongoing process and system upgrades which can impact our customers' experience in the short term, together with integrating recent acquisitions into our processes and systems, which may have a negative impact on our operating cash flows, liquidity and financial performance.
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, including at the individual IBX data center level. Although each individual IBX data center is currently performing in accordance 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.
2021. As of December 31, 2019,2021, we had over 10,000 customers worldwide. No one customer made up 10% or more of our retained earnings were $1.4 billion. Although we have generated net income for each fiscal year since 2008, excepttotal business revenues for the year ended December 31, 2014, we are currently investing heavily in2021.

We organize our sales force by customer type, as well as transaction costsby establishing a sales presence in diverse geographic regions, which enables efficient servicing of the customer base from a network of regional offices. We also support our customers with a global customer care organization.
Human Capital
As of December 31, 2021, we had 10,944 employees worldwide with 5,056 based in the Americas, 3,611 based in EMEA and interest expense,2,277 based in APAC. Of those employees, 4,693 employees were in engineering and operations, 1,855 employees were in sales and marketing and 4,396 employees were in management, finance and administration. As of December 31, 2021, approximately 74% of our workforce identified as men and approximately 25% identified as women. Women's representation in leadership (VP and above) increased from 28% to 31% year-over-year.
At Equinix, we strive to build a culture where every employee, every day, can say “I’m Safe, I Belong and I Matter” and where our workforce, at all levels, reflects and represents the communities in which we operate. Our objective is to continue to make our culture a critical competitive advantage, engaging every leader and every employee in the process. To ensure we are upholding our core corporate values and making progress towards our aspirational goals, we monitor employee satisfaction through a quarterly pulse survey, which is one of our listening mechanisms. In 2021, employee satisfaction scores ranged between 82 - 84 out of a 100 each quarter. We recognize that attracting, developing and retaining talent at all levels is vital to continuing our success and offer industry competitive compensation and benefits, along with development opportunities to help every employee achieve their full potential. The virtual recruiting environment necessitated by the global pandemic has created new opportunities for Equinix to find talent. We have benefited from new talent sourcing programs such as our global new-to-career programs as well as a pathways program to enable career transition for veterans and women returning to the workforce. In 2021, we continued to enhance our portfolio of development programs for our employees and introduced a system-enabled approach to goal setting and development planning to drive objectivity and achievement. We also continued to offer development tools and opportunities to our employees such as online learning, manager training, professional coaching and 360 degree assessments for eligible employees.

We are integrating a focus on diversity, inclusion and belonging ("DIB") into every aspect of how we run our business. In 2020, we embarked on a multi-year DIB strategy with governance through a DIB Council chaired by our CEO and CHRO, and in partnership with our Sustainability Program Office, that oversees our progress on environmental, social and governance ("ESG") matters. Our DIB strategy focuses on attracting, retaining and developing a diverse, global workforce; building leadership capability; and empowering our people to bring DIB to life. We are focused on creating multiple pathways to reach new talent from diverse communities. In 2021, we forged partnerships and invested in tools and systems to grow and support our inclusive hiring practices and made updates to our recruitment marketing to reach a wider candidate pool more effectively. We also embedded diversity and inclusive competencies and behaviors in our leadership profiles and added coaching tools as well as manager training on leading inclusive teams to our development program. Our Equinix Employee-led Connection Networks ("EECNs") are integral to our DIB strategy and play an important role in creating belonging and advocating for the needs and goals of communities with common identities, cultures or backgrounds. Each of our nine EECNs represents an identity/community that has faced historical discrimination or shares unique challenges. We recognize that creating the best workplace and culture we can requires a global effort with localized awareness and approaches. Late in 2020, we launched WeAreEquinix employee teams empowered to create, localize and promote purpose, inclusion and belonging for their locations across the world. Through live and virtual events, campaigns, and collaboration with the business, these volunteer leaders bring local opportunities to engage in the following areas: Wellbeing, Green and Sustainability, Community Impact, Fun and Creativity, Diversity, Inclusion and Belonging, and Employee Networks. We currently have WeAreEquinix teams in 15 locations.
In 2021, we launched our “I Matter” initiative to enable employees to voluntarily self-identify by adding their data across dimensions of diversity, including race/ethnicity, sexual orientation, gender identity, and disability in accordance with country regulations so that we may negativelybetter understand the global employee experience.
Equinix representatives have joined the G100 Talent Consortium Task Force on Racial Inequity in Business to consider core inequity issues, including anti-racism, bias, and hiring and promotability practices, in order to develop tangible best practices that companies can use as guide rails to increase representation and career mobility for black, indigenous and people of color ("BIPOC") employees. In 2021, we hosted a Days of Understanding event as part of an initiative of CEO ACT!ON, a pledge Equinix has taken along with hundreds of other companies to embrace difference in our organizations, educate our people and build more inclusive cultures inside and outside of our workplaces. As part of this partnership, three Equinix employees joined ACT!ON’s inaugural two-year fellowship program focused on identifying, developing, and promoting scalable and sustainable policies and corporate best practices that address systemic racism and social injustice to improve societal wellbeing. Equinix also joined the Alliance for Global Inclusion, a coalition of global organizations working together to bring inclusivity and full equity to the workplace. Finally, in 2021 Equinix partnered with McKinsey to provide leadership development to our Black/African American leaders through the Black Leadership Academy.
Our Community Impact program promotes connection and belonging, and enables employees to give back, with the support of Equinix, to the communities in which we work and live. In 2021, our employees volunteered at approximately 2,230 nonprofits worldwide.
We believe our commitment to the highest standards of honesty, integrity and ethical behavior differentiates our business as much as our technology. We promote these high standards through a number of policies including the Equinix Code of Business Conduct. All employees are required to complete trainings on ethics and the company’s anti-bribery and corruption policies. In addition, we maintain a confidential ethics helpline where employees are encouraged to speak up if they have any questions or concerns that our code is being violated. We have a zero-tolerance, non-retaliation policy that protects our employees when they speak up.
In a year again disrupted by the unprecedented global pandemic caused by COVID-19, we continued a number of precautionary measures in line with our business continuity and pandemic plans to minimize the risk of operational impacts and to protect the health and safety of employees, customers, partners and our communities. During the pandemic, we have focused on a careful, safe and responsible opening of our offices based on guidance from health experts and other leaders from around the world. As we look forward to the future of work, and more importantly amplifying Equinix’s vibrant culture, we are providing flexible, hybrid work opportunities in many roles, enhanced collaboration technologies for everyone, and activity-based workspaces at home or onsite. We recognize that the new normal will require changing behaviors. As such, we are providing learning opportunities and best practices to ensure our meetings, events and work sessions are inclusive and equitable for virtual and in-person participation. Employee well-being has been central to these efforts, driven globally through offerings such as health programs, ergonomic support, technology reimbursements, and wellness days.
12

We believe that all of these programs and initiatives support our human capital goals, align with our company culture, and increase employee satisfaction.

Sustainability
At Equinix, our Future First sustainability strategy rallies our people and partners to envision a better future and then do what it takes to make it happen. As the world’s digital infrastructure leader, we have the responsibility to harness the power of technology to create a more accessible, equitable and sustainable future. The ESG initiatives comprising our Future First strategy focus on the material issues that have the greatest impact on our stakeholders and our business. We continue to progress on our sustainability goals and look to build a business and world that reflects our purpose to bring the world together on our platform to create the innovations that will enrich our work, life and planet. We document our ESG progress in our Annual Report as well as in the annual Corporate Sustainability Report located on our sustainability website: sustainability.equinix.com.
In 2021, we committed to becoming climate neutral across our global operations by 2030 and set a validated science-based target (“SBT”) for emissions reduction across our global operations and supply chain. Our climate commitments are a critical step to ensure that we continue to advance investments and innovations to reduce greenhouse gas ("GHG") emissions and keep global warming to 1.5 degrees Celsius in alignment with the Paris Climate Agreement.
As a part of our Future First sustainability strategy, we published an Environmental Sustainability and Global Climate Change Policy in 2021 to detail our approach and practices related to the environment, climate change, resource efficiency and reporting. In alignment with our strategy and policy, we are also evaluating our material climate change risks and opportunities based on the recommendations of the Task Force on Climate Related Financial Disclosures (“TCFD”). We are continuing our work to embed climate change risk management into our business where relevant.
Environmental Performance
Equinix was the first data center company to commit to a long-term goal of 100% renewable energy across our global portfolio. We use local renewable energy sources where possible, seek new or recently built renewable sources and advocate for favorable renewable energy policies. In the U.S., we purchase more than 2.3 million megawatt-hours (MWh) of green power annually from a portfolio of renewable energy projects, including 225 MW of wind power under long-term virtual power purchase agreements (VPPAs) located in Texas and Oklahoma. In 2020, over 90% of our global electricity consumption, and 100% of U.S. electricity consumption, was covered by renewable energy sources.
We are committed to transparently measuring and reporting our global carbon footprint across direct (Scope 1), indirect energy (Scope 2) and indirect value chain (Scope 3) emissions. Since 2015, we have achieved a 50% reduction in GHG emissions on an absolute basis (Scope 1 and Scope 2 market-based metric tons of carbon dioxide-equivalent (mtCO2e)), even as the company doubled its footprint in both energy consumption and number of sites. In 2021, CDP, a global non-governmental organization dedicated to helping investors and companies measure and manage their climate risks, recognized our commitments, actions and progress on climate change.
13

We received an 'A-' CDP leadership score for climate action and annual disclosures within the CDP Climate Change survey.
We are leveraging technology and innovation to encourage commercialization of solutions that will enable the “Data Center of the Future”. To support our ongoing sustainability initiatives and commitment to innovation, we issued green bonds totaling $1.4 billion in 2020 and an additional $2.3 billion in 2021. Our Green Finance Framework aligns our sustainability commitments with our long-term financing needs and highlights our pipeline of green projects and data center innovations. In 2021, we allocated $2.9 billion in net proceeds to finance or refinance, in whole or in part, ongoing and new projects in categories of green buildings, renewable energy and energy efficiency.
We are committed to advancing environmental progress across other areas of our operations. While energy usage, specifically electricity, is our largest environmental impact, to address the growing importance of water within our operations, we launched a Sustainable Water Management Program in 2021. We consider the consumption of water in the design and operation of our facilities and are developing a coordinated global approach to water measurement and management. Through our efforts to establish the European Climate-Neutral Data Centre Operator Pact in 2021, Equinix and the EU data center industry have also committed to advancing initiatives beyond renewable energy and energy efficiency, including water efficiency, waste reduction, and circular economy principles.
Sustainability Accounting Standards Board ("SASB") Disclosures
SASB published the Sustainability Accounting Standard ("Standard") for the Real Estate Industry in October 2018. We have aligned our SASB disclosures with the Real Estate Standard to enhance corporate disclosure around ESG performance. In our comprehensive disclosures in our annual Corporate Sustainability Report we also document our progress against metrics as outlined in other frameworks such as the Global Reporting Initiative ("GRI"), UN Sustainable Development Goals ("SDGs") and TCFD. The following tables detail our energy metrics, aligned with the SASB Real Estate Standard. We intend to expand our reporting around the Real Estate Standard in the coming years.
The following metrics represent our colocation facilities performance in the calendar years specified. Energy, renewable energy and GHG emissions are independently assured to ISO 14064-3:2006 Standards for the quantification and reporting of GHG emissions (Scope 1, 2 and 3). Calendar year data for 2021 will become available in Q2 2022 and published in our annual Corporate Sustainability Report located on our sustainability website.

Energy Management: Green Building Ratings
Our environmental efforts aim to deliver meaningful and measurable progress against sustainability goals that positively impact our ability to sustain profitability in future periods unlesscustomers, partners, investors and until these new IBXemployees. Our data centers generate enough revenueare designed with high operational standards and energy efficiency in mind. Our data centers are planned holistically to exceed their operating costs and coverincorporate the 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 costsneeds of our recently-opened IBXcommunities and we aim to minimize the use of all resources in our operations. We evaluate cost-efficient opportunities to enhance energy efficiency and buy renewable energy for existing or acquired sites.
We are protecting our planet's resources by pioneering green data center innovations and building and operating energy-efficient data centers around the world. Our Energy Efficiency Center of Excellence is driving a global approach to cooling our existing data centers more efficiently. The program engages customers to manage their implementations more sustainably at our facilities, leading to overall improved site efficiencies.
We certify our data centers to numerous green buildings and energy management certifications and schemes. These include USGBC LEED green buildings certifications, ISO 14001:2015 Environmental Management Standard, ISO 50001:2011 Energy Management Standard, BCA Green Mark, U.S. EPA Energy Star for Data Centers and others.
Data centers receiving green building ratings in 2020 and 2021 covered 1.1 million gross sq. ft. While we have additional certifications that are pending final submissions, the following new sites received ratings in 2020 or 2021:

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
15

Table of operations.Contents
While we own certain of our IBX data centers, others are leased under long-term arrangements. 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 disrupt our business, harm our customer

relationships, expose us to liability under our customer contracts, cause us to take impairment charges and affect our operating results negatively.
We depend on a number of third parties to provide internet 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' 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' 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 internet connectivity to our IBX data centers that it will continue to do so for any period of time.
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 internet 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 have government customers, which subjects us to risks including early termination, audits, investigations, sanctions and penalties.
We derive 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 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'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 or seek bankruptcy protection 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's attention and resources. Results cannot be predicted with certainty and an adverse outcome in litigation could result in monetary damages or injunctive relief. 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-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 overturned network neutrality rules, which may result in material changes in the regulations and contribution regime affecting us and our customers. Furthermore, the U.S. Congress and state legislatures are reviewing and considering changes to the new FCC rules making the future of network 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 continue to evolve and must be addressed by Equinix as a global company.
We 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 internet and to related offerings such as 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 internet 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 internet 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.
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" 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 have a number of risks related to our qualification as a real estate investment trust for federal income tax purposes ("REIT"), including the risk that we may not be able to maintain our qualification as a REIT which could expose us to substantial corporate income tax and have a materially adverse effect on our business, financial condition, and results of operations.
ITEM 1.Business
Overview: Powering the World’s Digital Leaders
Equinix is the world's digital infrastructure companyTM. Digital leaders harness our trusted platform to bring together and interconnect the foundational infrastructure that powers their success. We enable our customers to access all the right places, partners and possibilities they need to accelerate their advantage. Platform Equinix® combines a global footprint of International Business Exchange™ ("IBX®") data centers in the Americas ("AMER"), Asia-Pacific ("APAC"), and Europe, the Middle East and Africa ("EMEA") regions, interconnection solutions, edge services, unique business and digital ecosystems and expert consulting and support. Equinix was incorporated on June 22, 1998 as a Delaware corporation and operates as a REIT for federal income tax purposes.
Al Avery and Jay Adelson founded Equinix as a vendor-neutral multi-tenant data center ("MTDC") provider where competing networks could connect and share data traffic to help scale the rapid growth of the early internet. The company’s name, Equinix (composed from the words "equality", "neutrality" and "internet exchange"), reflects that vision. The founders also believed they not only had the opportunity but also the responsibility to create a company that would be the steward of some of the most important digital infrastructure assets in the world. Two decades later, we have expanded upon that vision to build Platform Equinix, with unmatched scale and reach.
Our interconnected data centers around the world allow our customers to bring together and interconnect the infrastructure they need to fast-track their digital advantage. With Equinix, they can scale with agility, speed the launch of digital services, deliver world-class experiences and multiply their value. We enable them to differentiate by distributing infrastructure and removing the distance between clouds, users and applications in order to reduce latency and deliver a superior customer, partner and employee experience. The Equinix global platform, and the quality of our IBX data centers, interconnection offerings and edge services, have enabled us to establish a critical mass of customers. As more customers choose Platform Equinix for bandwidth cost and performance reasons, it benefits their suppliers and business partners to colocate in the same data centers and connect directly with each other. This adjacency creates a network effect that attracts new customers, continuously compounds our existing customers' value and enables them to capture further economic and performance benefits from our offerings.

In 2021, we opened nine new IBX data centers, opened six new xScaleTM data centers via our joint ventures, and entered three new markets resulting in an increase in our total number of IBX and xScale data center facilities to 240, which includes the MU4 and GN1 data centers which opened in January 2022. 2021 highlights include:
New data center openings included nine new IBX sites in the following metros: Bordeaux, Frankfurt, Genoa, Milan, Munich, Osaka, Perth, Silicon Valley and Singapore, with Bordeaux and Genoa being new market entries.
Six additional xScale sites opened in 2021 in Frankfurt, London, Osaka, Paris, Sao Paulo and Tokyo, bringing the total number of xScale data centers to eight. xScale data centers serve the needs of the growing hyperscale data center market, including the world's largest cloud service providers, and are engineered to meet the technical and operational requirements and price points of core hyperscale workload deployments. xScale data centers also offer access to our comprehensive suite of interconnection and edge services that tie into the hyperscale companies' existing access points at Equinix, thereby increasing the speed of connectivity to their existing and future enterprise customers. In xScale sites, hyperscale companies can consolidate core and access point deployments into one global provider to streamline and simplify their growth.
In December, we announced our expansion into Africa through the planned acquisition of MainOne, a leading West African data center and connectivity solutions provider, with presence in Nigeria, Ghana and Côte d'Ivoire. The transaction has an enterprise value of $320 million and marks the first step in Equinix's long-term strategy to become a leading African carrier neutral digital infrastructure company.

Industry Trends: Large-scale global trends are driving a digital-first strategy
Digital transformation is changing where and how businesses deploy and deliver IT services to employees and is creating new digital business models for partners and customers. The convergence of these global trends and the impact of the ongoing COVID-19 pandemic have created additional pressure for many companies to transform. The collective influence of these trends is driving complexity and risk that must be addressed in multiple locations for companies to effectively compete in the global digital economy. These trends include:
The Digital services trend is the continued digitizing of the back office to support digital business throughput. By 2022, 65% of global GDP will be digitalized, and most organizations will realize greater value by combining digitization and sustainability. This trend forces the need for a digital infrastructure optimized for proximity to, and interconnection with, networks and clouds. This in turn enables digital development with elastic scale and has contributed to a 3x increase in the multicloud, multiregion adoption rate over the last two years as businesses scale the digital core.
The Digital participation trend is digitizing trade and accessing digital marketplaces (digital B2B commerce). By 2025, 75% of organization leaders will leverage digital platforms and ecosystem capabilities to adapt their value chains to new markets, industries and ecosystems. This forces the need for organizations to interconnect digital infrastructure with research communities, supply chains and marketplaces, which enables composable business models. The fifth annual Global Interconnection Index ("GXI"), a market study published by Equinix, shows that SaaS is now the largest IT spend line item as companies move to public and private SaaS alternatives. Organizations that fail to leverage cloud, SaaS or partner digital ecosystems have shown two to three times slower growth over the past two years.
The Digital proximity trend means digitizing the front office for localized and personalized delivery—to customers, employees and operations where business happens, as well as digitizing the physical world for the physical infrastructure and operations intelligence needed to optimize commercial and environmental impact. Data shows that shifts in population and commerce centers will result in over 50% of new infrastructure being local by 2023, which will require a digital infrastructure in proximity to, and interconnecting, experiences, things (IoT) and intelligent operations.
These trends are accelerating the need for companies like Equinix who can provide a secure, agile global business platform that leverages digital interconnection—or private data exchange—to deliver real-time interactions around the world.
As part of their digital transformation, businesses in most industries are shifting their centralized IT infrastructures to the edge to bring digital services closer to users for better performance, which has become a significant driver of digital business value. To realize the full potential of the edge, IT organizations require greater interconnection bandwidth. Interconnection bandwidth is defined as the total capacity provisioned to privately and directly exchange traffic, with a diverse set of partners and providers, at distributed IT exchange points inside carrier-neutral colocation data centers. Private interconnection capacity between businesses, as reported in the GXI, is anticipated to grow at a compound annual growth rate of 44% by 2024, reaching 21,485+ terabits per second of data exchanged annually.

Competition
While a large number of enterprises and service providers, such as hyperscale cloud service providers, own their own data centers, we believe the industry is shifting away from single-tenant solutions to outsourcing some or all of their IT housing and interconnection requirements to third party facilities, such as those operated by us.
Historically, the outsourcing market was served by large telecommunications carriers who bundled their products and services with their colocation offerings. The data center market landscape has evolved to include private and vendor-neutral MTDC providers, hyperscale cloud providers, managed infrastructure and application hosting providers, and systems integrators. It is estimated that Equinix is one of more than 2,200 companies that provide MTDC offerings around the world. The global MTDC market is highly fragmented. Each of these data center solutions providers can bundle various colocation, interconnection and network offerings and outsourced IT infrastructure solutions. We believe that this outsourcing trend has accelerated and is likely to continue to accelerate in the coming years, especially in light of the movement to digital business as a result of the ongoing COVID-19 pandemic.
Equinix is differentiated in this market by being able to offer customers a global platform that reaches 27 countries and contains the industry’s largest and most active ecosystem of partners in our sites. This ecosystem creates a “network effect” which improves performance and lowers cost for our customers and is a significant source of competitive advantage for Equinix.
Customers
Our customers include telecommunications carriers, mobile and other network services providers, cloud and IT services providers, digital media and content providers, financial services companies, and global enterprise ecosystems in various industries. We provide each company access to a choice of business partners and solutions based on their colocation, interconnection and managed IT service needs, and delivered 99.999% operational uptime across our global data centers in 2021. As of December 31, 2021, we had over 10,000 customers worldwide. No one customer made up 10% or more of our total business revenues for the year ended December 31, 2021.

The following companies represent some of our leading customers and partners:
eqix-20211231_g5.jpg
We serve our customers with a direct sales force and channel marketing program. We organize our sales force by customer type, as well as by establishing a sales presence in diverse geographic regions, which enables efficient servicing of the customer base from a network of regional offices. We also support our customers with a global customer care organization.
Human Capital
As of December 31, 2021, we had 10,944 employees worldwide with 5,056 based in the Americas, 3,611 based in EMEA and 2,277 based in APAC. Of those employees, 4,693 employees were in engineering and operations, 1,855 employees were in sales and marketing and 4,396 employees were in management, finance and administration. As of December 31, 2021, approximately 74% of our workforce identified as men and approximately 25% identified as women. Women's representation in leadership (VP and above) increased from 28% to 31% year-over-year.
At Equinix, we strive to build a culture where every employee, every day, can say “I’m Safe, I Belong and I Matter” and where our workforce, at all levels, reflects and represents the communities in which we operate. Our objective is to continue to make our culture a critical competitive advantage, engaging every leader and every employee in the process. To ensure we are upholding our core corporate values and making progress towards our aspirational goals, we monitor employee satisfaction through a quarterly pulse survey, which is one of our listening mechanisms. In 2021, employee satisfaction scores ranged between 82 - 84 out of a 100 each quarter. We recognize that attracting, developing and retaining talent at all levels is vital to continuing our success and offer industry competitive compensation and benefits, along with development opportunities to help every employee achieve their full potential. The virtual recruiting environment necessitated by the global pandemic has created new opportunities for Equinix to find talent. We have benefited from new talent sourcing programs such as our global new-to-career programs as well as a pathways program to enable career transition for veterans and women returning to the workforce. In 2021, we continued to enhance our portfolio of development programs for our employees and introduced a system-enabled approach to goal setting and development planning to drive objectivity and achievement. We also continued to offer development tools and opportunities to our employees such as online learning, manager training, professional coaching and 360 degree assessments for eligible employees.
11

We are integrating a focus on diversity, inclusion and belonging ("DIB") into every aspect of how we run our business. In 2020, we embarked on a multi-year DIB strategy with governance through a DIB Council chaired by our CEO and CHRO, and in partnership with our Sustainability Program Office, that oversees our progress on environmental, social and governance ("ESG") matters. Our DIB strategy focuses on attracting, retaining and developing a diverse, global workforce; building leadership capability; and empowering our people to bring DIB to life. We are focused on creating multiple pathways to reach new talent from diverse communities. In 2021, we forged partnerships and invested in tools and systems to grow and support our inclusive hiring practices and made updates to our recruitment marketing to reach a wider candidate pool more effectively. We also embedded diversity and inclusive competencies and behaviors in our leadership profiles and added coaching tools as well as manager training on leading inclusive teams to our development program. Our Equinix Employee-led Connection Networks ("EECNs") are integral to our DIB strategy and play an important role in creating belonging and advocating for the needs and goals of communities with common identities, cultures or backgrounds. Each of our nine EECNs represents an identity/community that has faced historical discrimination or shares unique challenges. We recognize that creating the best workplace and culture we can requires a global effort with localized awareness and approaches. Late in 2020, we launched WeAreEquinix employee teams empowered to create, localize and promote purpose, inclusion and belonging for their locations across the world. Through live and virtual events, campaigns, and collaboration with the business, these volunteer leaders bring local opportunities to engage in the following areas: Wellbeing, Green and Sustainability, Community Impact, Fun and Creativity, Diversity, Inclusion and Belonging, and Employee Networks. We currently have WeAreEquinix teams in 15 locations.
In 2021, we launched our “I Matter” initiative to enable employees to voluntarily self-identify by adding their data across dimensions of diversity, including race/ethnicity, sexual orientation, gender identity, and disability in accordance with country regulations so that we may better understand the global employee experience.
Equinix representatives have joined the G100 Talent Consortium Task Force on Racial Inequity in Business to consider core inequity issues, including anti-racism, bias, and hiring and promotability practices, in order to develop tangible best practices that companies can use as guide rails to increase representation and career mobility for black, indigenous and people of color ("BIPOC") employees. In 2021, we hosted a Days of Understanding event as part of an initiative of CEO ACT!ON, a pledge Equinix has taken along with hundreds of other companies to embrace difference in our organizations, educate our people and build more inclusive cultures inside and outside of our workplaces. As part of this partnership, three Equinix employees joined ACT!ON’s inaugural two-year fellowship program focused on identifying, developing, and promoting scalable and sustainable policies and corporate best practices that address systemic racism and social injustice to improve societal wellbeing. Equinix also joined the Alliance for Global Inclusion, a coalition of global organizations working together to bring inclusivity and full equity to the workplace. Finally, in 2021 Equinix partnered with McKinsey to provide leadership development to our Black/African American leaders through the Black Leadership Academy.
Our Community Impact program promotes connection and belonging, and enables employees to give back, with the support of Equinix, to the communities in which we work and live. In 2021, our employees volunteered at approximately 2,230 nonprofits worldwide.
We believe our commitment to the highest standards of honesty, integrity and ethical behavior differentiates our business as much as our technology. We promote these high standards through a number of policies including the Equinix Code of Business Conduct. All employees are required to complete trainings on ethics and the company’s anti-bribery and corruption policies. In addition, we maintain a confidential ethics helpline where employees are encouraged to speak up if they have any questions or concerns that our code is being violated. We have a zero-tolerance, non-retaliation policy that protects our employees when they speak up.
In a year again disrupted by the unprecedented global pandemic caused by COVID-19, we continued a number of precautionary measures in line with our business continuity and pandemic plans to minimize the risk of operational impacts and to protect the health and safety of employees, customers, partners and our communities. During the pandemic, we have focused on a careful, safe and responsible opening of our offices based on guidance from health experts and other leaders from around the world. As we look forward to the future of work, and more importantly amplifying Equinix’s vibrant culture, we are providing flexible, hybrid work opportunities in many roles, enhanced collaboration technologies for everyone, and activity-based workspaces at home or onsite. We recognize that the new normal will require changing behaviors. As such, we are providing learning opportunities and best practices to ensure our meetings, events and work sessions are inclusive and equitable for virtual and in-person participation. Employee well-being has been central to these efforts, driven globally through offerings such as health programs, ergonomic support, technology reimbursements, and wellness days.
12

We believe that all of these programs and initiatives support our human capital goals, align with our company culture, and increase employee satisfaction.

Sustainability
At Equinix, our Future First sustainability strategy rallies our people and partners to envision a better future and then do what it takes to make it happen. As the world’s digital infrastructure leader, we have the responsibility to harness the power of technology to create a more accessible, equitable and sustainable future. The ESG initiatives comprising our Future First strategy focus on the material issues that have the greatest impact on our stakeholders and our business. We continue to progress on our sustainability goals and look to build a business and world that reflects our purpose to bring the world together on our platform to create the innovations that will enrich our work, life and planet. We document our ESG progress in our Annual Report as well as in the annual Corporate Sustainability Report located on our sustainability website: sustainability.equinix.com.
In 2021, we committed to becoming climate neutral across our global operations by 2030 and set a validated science-based target (“SBT”) for emissions reduction across our global operations and supply chain. Our climate commitments are a critical step to ensure that we continue to advance investments and innovations to reduce greenhouse gas ("GHG") emissions and keep global warming to 1.5 degrees Celsius in alignment with the Paris Climate Agreement.
As a part of our Future First sustainability strategy, we published an Environmental Sustainability and Global Climate Change Policy in 2021 to detail our approach and practices related to the environment, climate change, resource efficiency and reporting. In alignment with our strategy and policy, we are also evaluating our material climate change risks and opportunities based on the recommendations of the Task Force on Climate Related Financial Disclosures (“TCFD”). We are continuing our work to embed climate change risk management into our business where relevant.
Environmental Performance
Equinix was the first data center company to commit to a long-term goal of 100% renewable energy across our global portfolio. We use local renewable energy sources where possible, seek new or recently built renewable sources and advocate for favorable renewable energy policies. In the U.S., we purchase more than 2.3 million megawatt-hours (MWh) of green power annually from a portfolio of renewable energy projects, including 225 MW of wind power under long-term virtual power purchase agreements (VPPAs) located in Texas and Oklahoma. In 2020, over 90% of our global electricity consumption, and 100% of U.S. electricity consumption, was covered by renewable energy sources.
We are committed to transparently measuring and reporting our global carbon footprint across direct (Scope 1), indirect energy (Scope 2) and indirect value chain (Scope 3) emissions. Since 2015, we have achieved a 50% reduction in GHG emissions on an absolute basis (Scope 1 and Scope 2 market-based metric tons of carbon dioxide-equivalent (mtCO2e)), even as the company doubled its footprint in both energy consumption and number of sites. In 2021, CDP, a global non-governmental organization dedicated to helping investors and companies measure and manage their climate risks, recognized our commitments, actions and progress on climate change.
13

We received an 'A-' CDP leadership score for climate action and annual disclosures within the CDP Climate Change survey.
We are leveraging technology and innovation to encourage commercialization of solutions that will enable the “Data Center of the Future”. To support our ongoing sustainability initiatives and commitment to innovation, we issued green bonds totaling $1.4 billion in 2020 and an additional $2.3 billion in 2021. Our Green Finance Framework aligns our sustainability commitments with our long-term financing needs and highlights our pipeline of green projects and data center innovations. In 2021, we allocated $2.9 billion in net proceeds to finance or refinance, in whole or in part, ongoing and new projects in categories of green buildings, renewable energy and energy efficiency.
We are committed to advancing environmental progress across other areas of our operations. While energy usage, specifically electricity, is our largest environmental impact, to address the growing importance of water within our operations, we launched a Sustainable Water Management Program in 2021. We consider the consumption of water in the design and operation of our facilities and are developing a coordinated global approach to water measurement and management. Through our efforts to establish the European Climate-Neutral Data Centre Operator Pact in 2021, Equinix and the EU data center industry have also committed to advancing initiatives beyond renewable energy and energy efficiency, including water efficiency, waste reduction, and circular economy principles.
Sustainability Accounting Standards Board ("SASB") Disclosures
SASB published the Sustainability Accounting Standard ("Standard") for the Real Estate Industry in October 2018. We have aligned our SASB disclosures with the Real Estate Standard to enhance corporate disclosure around ESG performance. In our comprehensive disclosures in our annual Corporate Sustainability Report we also document our progress against metrics as outlined in other frameworks such as the Global Reporting Initiative ("GRI"), UN Sustainable Development Goals ("SDGs") and TCFD. The following tables detail our energy metrics, aligned with the SASB Real Estate Standard. We intend to expand our reporting around the Real Estate Standard in the coming years.
The following metrics represent our colocation facilities performance in the calendar years specified. Energy, renewable energy and GHG emissions are independently assured to ISO 14064-3:2006 Standards for the quantification and reporting of GHG emissions (Scope 1, 2 and 3). Calendar year data for 2021 will become available in Q2 2022 and published in our annual Corporate Sustainability Report located on our sustainability website.

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:
Risk Factors

Risks Related to Our Business and Our Operations

The ongoing COVID-19 pandemic could have a negative effect on our business, results of operations and financial condition.

We have continuously monitored our global operations as the COVID-19 pandemic has spread across the globe and as variants and vaccines have developed. We have implemented procedures focusing on the health and safety of our employees, customers, partners and communities, the continuity of our business offerings and compliance with governmental regulations and local public health guidance and ordinances. We have activated our business continuity and pandemic plans and while our business operations have continued without interruption and our IBX data centers have remained fully operational to date, we cannot guarantee our business operations or our IBX data centers will not be negatively impacted in the future. Our IBX data centers have been designated “essential businesses” or “critical infrastructure” for purposes of remaining open during the COVID-19 pandemic in all of the jurisdictions that have published these exemptions but not all jurisdictions have created such designations. Any change in these classifications could cause operational disruptions or closures of the affected IBX data centers.

We implemented processes to limit and schedule access to certain IBX data centers based on infection rates and case counts as well as implemented social distancing and hygiene protocols. We have continued to track infections and adapt our policies and procedures based on a number of factors including the COVID-19 pandemic severity in each office and IBX location. These proactive actions we have taken or may take in the future and any restrictions imposed by the government could result in business delays, operational disruption and customer dissatisfaction. Employee illnesses resulting from the pandemic could result in further inefficiencies or delays and a suspected or confirmed case in an IBX data center could require temporary closure of the affected IBX data center for cleaning or until local regulatory requirements are fulfilled. Any closure of an IBX data center or limitation of customer access could cause customer dissatisfaction if customers are unable to access their equipment within the IBX data center. We also have service level agreements which could be affected if we are required to close an IBX data center for any reason.

Preventative measures instituted by governments and businesses to mitigate the spread of COVID-19, including travel restrictions, social distancing requirements, shelter in place orders and quarantines, have negatively impacted the global economy and may adversely impact us, our customers and vendors. Given the uncertainty around the duration and extent of the ongoing COVID-19 pandemic, we cannot accurately predict at this time how the pandemic will affect our business over time.

The COVID-19 pandemic has contributed to certain global supply chain disruptions including the supply of certain construction materials and has contributed to overall inflation. While we do not expect the construction delays and supply chain disruptions that we are currently experiencing to have a material effect on us at this time, additional disruptions because of the ongoing COVID-19 pandemic could occur. Additional or unexpected disruptions could cause construction delays or significantly affect the cost of our planned expansion projects in the future. Significant construction delays and increases in costs because of the supply chain disruptions could interfere with our ability to meet commitments to customers who have contracted for space in new IBX data centers under construction and could have a material impact on our business. While we have received "essential business" permits for construction in some jurisdictions, these classifications may not extend to the construction of new IBX data centers in all of our jurisdictions. We are also reliant on third party construction labor to build and expand our IBX data centers, to which we may not have access due to the ongoing COVID-19 pandemic. We rely on materials, products and manufacturing from regions of the world which are impacted by the pandemic and supply chain disruptions. While we have invested in creating a material inventory to mitigate global increases in raw materials, energy and labor prices, it may not be sufficient and ongoing delays, difficulty finding replacement products and continued high inflation could affect our business and growth.

Although currently stayed while being litigated in U.S. courts, U.S. Presidential Executive Order (EO 14042) requires companies that do business with the U.S. Federal government (“Government Contractors”) to implement a
17

mandate for all their U.S. employees to be fully vaccinated against COVID-19 (the “US Vaccine Mandate”). As a Government Contractor, we will be required to comply with the US Vaccine Mandate if it or a similar vaccine mandate for Government Contractors goes into effect. We do not anticipate the US Vaccine Mandate to have a material negative effect on our business even if it goes into effect, but if we experience more employee turnover than we expect or if similar mandates are required in other regions, we could experience disruptions to certain functions and employee satisfaction could be affected.

While the full extent and impact of the ongoing COVID-19 pandemic cannot be reasonably estimated at this time, it could have a material adverse impact on our business and financial condition. The extent to which the ongoing COVID-19 pandemic will impact our financial condition or results of operations will depend on many factors and future developments, including new information about the ongoing COVID-19 pandemic and its variants, additional surges in infection rates, vaccine efforts and any new government regulations which may emerge to contain the virus, among others.

We experienced an information technology security breach in the past and may be vulnerable to future security breaches, which could disrupt our operations and have a material adverse effect on our business results of operation and financial performance.

Despite our efforts to protect against cyber-attacks, we are not fully insulated from these types of security breaches, and such an attack could adversely impact our competitiveness and results of operations. In September 2020, we discovered ransomware on certain of our internal systems, encrypting files and holding them for ransom. Our teams responded quickly to address the incident and notified law enforcement, and after a thorough review of the incident by our management and experts retained to assist in this incident, the investigation was closed as of October 14, 2020. Our IBX data centers and our service offerings, including managed services, remained fully operational during the attack and the incident did not affect our ability to support our customers. We further believe that we were able to contain the incident and that the resolution will prevent the release of any data associated with this attack. While the event has been resolved and has not caused a material disruption to our systems nor resulted in any material costs to us, we are also working to protect against any future attacks. We will continue to face risks associated with unauthorized access to our computer systems, loss or destruction of data, computer viruses, ransomware, malware, distributed denial-of-service attacks or other malicious activities. These threats may result from human error, equipment failure, fraud or malice on the part of employees, vendors or third parties. 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. Because of the ongoing COVID-19 pandemic, many of our non-IBX employees are working from home and could potentially be exposed to new security risks or attempted breaches because of these new work environments. Our adaptation to a hybrid working model that includes both work from home and in an office could continue to expose us to new security risks. 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. Any breaches that may occur in the future 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 results of operations. 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 we were held responsible for any such breach, it could result in a significant loss to us, including damage to our client relationships, harm to our brand and reputation, and legal liability.

Terrorist activity, or other acts of violence, including violence stemming from the current climate of political and economic uncertainty, could adversely impact our business.
18


The continued threat of terrorist activity and other acts of war or hostility both domestically and abroad by terrorist organizations, organized crime organizations, or other criminals along with violence stemming from political unrest, contribute to a climate of political and economic uncertainty in many of the regions in which we operate. Due to existing or developing circumstances, we may need to incur additional costs in the future to provide enhanced security, including cyber security and physical 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 and employees, our ability to raise capital and the operation and maintenance of our IBX data centers.

Our offerings have a long sales cycle that may harm our revenue and results of operations.

A customer'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 to pursuing a particular sale or customer that does not result in revenues.

Delays due to the length of our sales cycle may materially and adversely affect our revenues and results of operations, which could harm our ability to meet our forecasts and cause volatility in our stock price.

Any failure of our physical infrastructure or negative impact on our ability to meet our obligations to our customers, 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 safeguard our customers' infrastructure and equipment located in our IBX data centers and ensure our IBX data centers and non-IBX offices remain operational at all times. 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 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 buildings 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 IBX data centers. Newly acquired data centers also may not have the same power infrastructure and design in place as our own IBX data centers. These legacy designs could require upgrades in order to meet our standards and our customers’ expectations. Until the legacy systems are brought up to our standards, customers in these legacy IBX data centers could be exposed to higher risks of unexpected power outages. We have experienced power outages because of these legacy design issues in the past and our customers could experience these in the future.

Problems at one or more of our IBX data centers or corporate offices, whether or not within our control, could result in service interruptions or significant infrastructure or equipment damage. These could result from numerous factors, including but not limited to:

human error;
equipment failure;
physical, electronic and cyber security breaches;
fire, earthquake, hurricane, flood, tornado and other natural disasters;
extreme temperatures;
water damage;
fiber cuts;
power loss;
terrorist acts;
sabotage and vandalism;
global pandemics such as the COVID-19 pandemic;
inability of our operations employees to access our IBX data centers for any reason; and
failure of business partners who provide our resale products.

19

We have service level commitment obligations to certain customers. As a result, service interruptions or significant equipment damage in our IBX data centers could result in difficulty maintaining service level commitments to these customers and potential claims related to such failures. Because our IBX data centers are critical to many of our 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 results of operations.

Furthermore, we are dependent upon internet 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.

Our IBX data center employees are critical to our ability to maintain our business operations and reach our service level commitments. Although we have redundancies built into our network, if our IBX employees are unable to access our IBX data centers for any reason, we could experience operational issues at the affected site. Pandemics, weather and climate related crises or any other social, political, or economic disruption in the U.S. or abroad could prevent sufficient staffing at our IBX data centers and have a material adverse impact on our operations.

We are currently making significant investments in our back-office information technology systems and processes. Difficulties from or disruptions to these efforts may interrupt our normal operations and adversely affect our business and results of operations.

We have been investing heavily in 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 we operate in. These continuing investments include: 1) ongoing improvements to the customer experience from initial quote to customer billing and our revenue recognition process; 2) integration of recently-acquired operations onto our various information technology systems; and 3) implementation of new tools and technologies to either further streamline and automate processes, or to support our compliance with evolving U.S. GAAP. Our finance team is also working on a multi-year project to move the backbone of our finance systems to the cloud. As a result of our continued work on these projects, we may experience difficulties with our systems, management distraction and significant business disruptions. For 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 us 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 difficulties or disruptions may adversely affect our business and results of operations.

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
20

contain industry standard exclusions for events such as war and nuclear reaction. We purchase earthquake insurance for certain of our IBX data centers, but for our IBX data centers in high-risk zones, including those in California and Japan, 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.

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 IBX data 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 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'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 we are unable to implement our evolving organizational structure or 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, we continue to review our organizational architecture and have made, and will continue to make, changes as appropriate. There can be no assurances that any of these changes will not result in attrition, that the significant amount of management and other employees' time and focus to implement the changes will not divert attention from operating and growing the business, or that any changes will result in increased organizational effectiveness. We must also continue to identify, hire, train and retain key personnel who maintain relationships with our customers and who can provide the technical, strategic and marketing skills required for our 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 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 we are one of more than 1,200 companies that provide these offerings around the world. We compete 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.

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, we 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.

If we cannot continue to develop, acquire, market and provide new offerings or enhancements to existing offerings that meet customer requirements and differentiate us from our competitors, our results of operations could suffer.
21


As our customers evolve their IT strategies, we must remain flexible and evolve along with new technologies and industry and market shifts. Ineffective planning and execution in our cloud and product development strategies may cause difficulty in sustaining our competitive advantages.

The process of developing and acquiring new offerings and enhancing existing offerings is complex. If we fail to anticipate customers’ evolving needs and expectations or do not adapt to technological and IT trends, our results of operations could suffer. In order to adapt effectively, we sometimes must make long-term investments, develop, acquire or obtain certain intellectual property and commit significant resources before knowing whether our predictions will accurately reflect customer demand for the new offerings. If we misjudge customer needs in the future, our new offerings may not succeed, and our revenues and earnings may be harmed. Additionally, any delay in the development, acquisition, marketing or launch of a new offering could result in customer dissatisfaction or attrition. If we cannot continue adapting our products, or if our competitors can adapt their products more quickly than us, our business could be harmed.

We have recently invested in joint ventures in order to develop capacity to serve the large footprint needs of a targeted set of hyperscale customers by leveraging existing capacity and dedicated hyperscale builds. We have announced our intention to seek additional joint venture partners for certain of our hyperscale builds. There can be no assurances that our joint ventures will be successful or that we find additional partners or that we are able to successfully meet the needs of these customers.

In 2020, we also acquired Packet Host, Inc. ("Packet"), a bare metal automation company to facilitate a new hardware product offering for us and we expect to continue to consider other new product offerings for our customers. Hardware solutions are a new market area for us which can bring challenges and could harm our business if not executed in the time or manner that we expect. While we believe this new product offering and others we may implement in the future will be desirable to our customers and will complement our other offerings on Platform Equinix, we cannot guarantee the success of this product or any other new product offering.

Our results of operations may fluctuate.

We have experienced fluctuations in our results of operations on a quarterly and annual basis. The fluctuations in our results of operations may cause the market price of our common stock to be volatile. We may experience significant fluctuations in our results of operations 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 solutions at our IBX data centers;
increased costs of power;
changes in general economic conditions, such as those stemming from pandemics or other economic downturns, or specific market conditions in the telecommunications and internet industries, any of which could have a material impact on us or 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's operations;
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;
additions and changes in product offerings and our ability to ramp up and integrate new products 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;
22

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 electricity;
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 GAAP as periodically released by the Financial Accounting Standards Board ("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 results of operations. 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 results of operations in one or more future quarters may fail to meet the expectations of securities analysts or investors.

Our DSO may be negatively impacted by process and system upgrades and acquisitions.

Our DSO may be negatively impacted by ongoing process and system upgrades which can impact our customers' experience in the short term, together with integrating recent acquisitions into our processes and systems, which may have a negative impact on our operating cash flows, liquidity and financial condition.

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, including at the individual IBX data center level. Although each individual IBX data center is currently performing in accordance
23

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, 2021, our retained earnings were $2.3 billion. Although we have generated net income for each fiscal year since 2008, except for the year ended December 31, 2014, we are currently investing heavily in our future growth through the build out of multiple additional IBX data centers, expansions of IBX data centers and acquisitions of complementary businesses. As a result, we will incur higher depreciation and other operating expenses, as well as transaction 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 the 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. These leased IBX data 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 disrupt our business, harm our customer relationships, expose us to liability under our customer contracts, cause us to take impairment charges and affect our results of operations negatively.

We depend on a number of third parties to provide internet connectivity to our IBX data centers; if connectivity is interrupted or terminated, our results of operations and cash flow could be materially and adversely affected.

The presence of diverse telecommunications 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' customers to encourage them to invest the capital and operating resources required to connect from their data 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 internet connectivity to our IBX data centers that it will continue to do so for any period of time.

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.

24

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.

If the establishment of highly diverse internet connectivity to our IBX data centers does not occur, is materially delayed or is discontinued, or is subject to failure, our results of operations and financial condition will be adversely affected.

We have government customers, which subjects us to risks including early termination, audits, investigations, sanctions and penalties.

We derive 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.

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.

Additionally, as a Government Contractor, we could be subject to additional orders and laws such as the US Vaccine Mandate which could have a material adverse effect on our employee satisfaction and our 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 results of operations.

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 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'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, any uncertain global economic climate, including the one we are currently experiencing as a result of the ongoing COVID-19 pandemic, could 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 or seek bankruptcy protection 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.

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.

Our business could be harmed by increased costs to procure power, prolonged power outages, shortages or capacity constraints.

Any power outages, shortages, capacity constraints or significant increase in the cost of power may have an adverse effect on our business and our results of operations.

In each of our markets, we rely on third parties, and their infrastructure, to provide a sufficient amount of power for current and future customers. At the same time, power and cooling requirements are increasing per unit of equipment. 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, which can result in growth in the aggregate power consumption of our facilities beyond our original plan and expectations. This means that limitations on the capacity of our electrical delivery systems and equipment could limit customer utilization of our IBX data centers. These limitations 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, results of operations and cash flows.

Our IBX data centers are affected by problems accessing electricity sources, such as planned or unplanned power outages and limitations on transmission or distribution. Unplanned power outages, including, but not limited to those relating to large storms, earthquakes, fires, tsunamis, cyberattacks, and any failures of electrical power grids more generally, and planned power outages by public utilities, such as those related to Pacific Gas and Electric Company's planned outages in California to minimize fire risks, could harm our customers and our business. Many of our employees in California are still working from home because of the ongoing COVID-19 pandemic and they could be subjected to planned power outages at home which could be difficult to track and could affect our day to day operations of our non-IBX employees. Our international operations are sometimes located outside of developed, reliable electricity markets, where we are exposed to some insecurity in supply associated with technical and regulatory problems, as well as transmission constraints. Some of our IBX 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. We attempt to limit our exposure to system downtime by using backup generators and alternative power supplies, but these measures may not always prevent downtime, which can adversely affect customer experience and revenues.

We are currently experiencing inflation and volatility pressures in the energy market globally. In particular, current dislocation in the Singapore power market has resulted in Equinix having to buy power at extremely elevated spot rates and this ongoing price volatility impacted elements of our 2022 financial projections. Various macroeconomic factors are contributing to the instability and global power shortage including the COVID-19 pandemic, severe weather events, governmental regulations, government relations and inflation. The price for power in many of the countries in which we operate has seen significant increases in recent months, and it is unclear when the markets will stabilize. While we have aimed to minimize our risk exposure related to power procurement in Singapore and globally via hedging, conservation, and other efficiencies, we expect the cost for power to continue to be volatile and unpredictable and subject to inflationary pressures. We believe we have made appropriate estimates for these costs in our forecasting but the unpredictable energy market at this time could materially affect our financial forecasting, results of operations and financial condition.

Each new facility requires access to significant quantities of electricity. Limitations on generation, transmission and distribution may limit our ability to obtain 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.

Risks Related to Our Expansion Plans

Our construction of 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 may 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. These construction projects expose us to many risks which could have an adverse effect on our results of operations and financial condition. The ongoing COVID-19 pandemic, supply chain issues and inflation have
26

exacerbated many of these construction risks and created additional risks for our business. Some of the risks associated with construction 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 and delays in obtaining building supplies, raw materials and data center equipment;
labor availability, labor disputes and work stoppages with contractors, subcontractors and other third parties, including interruptions in work due to the ongoing COVID-19 pandemic;
unanticipated environmental issues and geological problems;
delays related to permitting and approvals to open from public agencies and utility companies;
delays in site readiness leading to our failure to meet commitments made to customers planning to expand into a new build; and
unanticipated customer requirements that would necessitate alternative data center design, making our sites less desirable or leading to increased costs in order to make necessary modifications or retrofits.

We are currently experiencing rising construction costs which reflect the increase in cost of labor and raw materials, supply chain and logistic challenges, and high demand in our sector. While we have invested in creating a material inventory to mitigate supply chain issues and inflation, it may not be sufficient and ongoing delays, difficulty finding replacement products and continued high inflation could affect our business and growth and could have a material effect on our business. Additional or unexpected disruptions to our supply chain or inflationary pressures could significantly affect the cost of our planned expansion projects and interfere with our ability to meet commitments to customers who have contracted for space in new IBX data centers under construction.

Construction projects are dependent on permitting from public agencies and utility companies. Any delay in permitting could affect our growth. We are currently experiencing permitting delays in most metros due to reduced production from labor availability and from other COVID-19 pandemic related permitting restrictions or stoppages. While we don't currently anticipate any material long-term negative impact to our business because of these construction delays, these types of delays and stoppages related to permitting from public agencies and utility companies could worsen and have an adverse effect on our bookings, revenue or growth.

Additionally, all construction related 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, significant subcontractor or key supplier experience financial problems or other problems 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 metro connect solutions to connect these two IBX data 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.

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, we have completed numerous acquisitions, including most recently that of GPX Global System's, Inc.'s India operations in September 2021, certain data centers from BCE Inc. ("Bell") in Canada in the fourth quarter of 2020, Packet in March 2020, and three data centers from Axtel S.A.B. de C.V. ("Axtel") in Mexico in January 2020. In 2021 we also announced our intention to acquire MainOne, a leading West African data center and connectivity solutions provider, with operations in Nigeria, Ghana and Côte d'Ivoire. We expect to make additional acquisitions in the future, which may include (i) acquisitions of businesses, products, solutions or technologies that we believe to be complementary, (ii) acquisitions of new IBX data centers or real estate for
27

development of new IBX data centers; (iii) acquisitions through investments in local data center operators; or (iv) acquisitions in new markets with higher risk profiles. 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, many of which could be exacerbated by the ongoing COVID-19 pandemic, including:

the possible disruption of our ongoing business and diversion of management's attention by acquisition, transition and integration activities, particularly when multiple acquisitions and integrations are occurring at the same time or when we are entering an emerging market with a higher risk profile;
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 adverse effects resulting from such uncertainty;
the possibility that our projections about the success of an acquisition could be inaccurate and any such inaccuracies could have a material adverse effect on our financial projections;
the dilution of our existing stockholders as a result of our issuing stock as consideration in a transaction or selling stock in 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;
the possibility that we may be unable to integrate certain IT systems that do not meet Equinix's standard requirements with respect to security, privacy or any other standard;
the potential deterioration in 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" of a new or different IBX data center;
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;
28

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 and we may become subject to complex requirements and risks with which we have limited experience;
the possibility that future acquisitions may appear less attractive due to fluctuations in foreign currency rates;
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;
the possibility of pre-existing undisclosed liabilities, including, but not limited to, lease or landlord related liability, tax liability, environmental liability or asbestos liability, for which insurance coverage may be insufficient or unavailable, or other issues not discovered in the diligence process;
the possibility that we receive limited or incorrect information about the acquired business in the diligence process, particularly in light of the travel bans and other restrictions imposed due to the COVID-19 pandemic; and
the possibility that we do not have full visibility into customer agreements and customer termination rights during the diligence process which could expose us to additional liabilities after completing the acquisition.

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.

The anticipated benefits of our Joint Ventures may not be fully realized, or take longer to realize than expected.

We have entered into joint ventures to develop and operate xScale™ data centers (together, the “Joint Ventures”). Equinix owns a 20% interest and our JV partners own an 80% interest in each joint venture, and Equinix operates all facilities.

Certain sites that are intended to be utilized in Joint Ventures require investment for development. The success of these Joint Ventures will depend, in part, on the successful development of the data center sites, and we may not realize all of the anticipated benefits. Such development may be more difficult, time-consuming or costly than expected and 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. Additionally, if it is determined these sites are no longer desirable for the Joint Ventures, we would need to adapt such sites for other purposes.
29


We may not realize all of the anticipated benefits from our Joint Ventures. The success of these Joint Ventures will depend, in part, on the successful partnership between Equinix and our JV partners. Such a partnership is subject to risks as outlined below in our risk factor related to new joint ventures, and more generally, to the same types of business risks as would impact our IBX data center business. A failure to successfully partner, or a failure to realize our expectations for the Joint Ventures, could materially impact our business, financial condition and results of operations. These Joint Ventures could also be negatively impacted by development and construction delays, including those resulting from the ongoing COVID-19 pandemic.

Joint venture investments could expose us to risks and liabilities in connection with the formation of the new joint ventures, the operation of such joint ventures without sole decision-making authority, and our reliance on joint venture partners who may have economic and business interests that are inconsistent with our business interests.

In addition to our current and proposed Joint Ventures, we may co-invest with other third parties through partnerships, joint ventures or other entities in the future. These joint ventures could result in our acquisition of non-controlling interests in, or shared responsibility for, managing the affairs of a property or portfolio of properties, partnership, joint venture or other entity. We may be subject to additional risks, including:

we may not have the right to exercise sole decision-making authority regarding the properties, partnership, joint venture or other entity;
if our partners become bankrupt or fail to fund their share of required capital contributions, we may choose to or be required to contribute such capital;
our partners may have economic, tax or other business interests or goals which are inconsistent with our business interests or goals, and may be in a position to take actions contrary to our policies or objectives;
our joint venture partners may take actions that are not within our control, which could require us to dispose of the joint venture asset, transfer it to a TRS in order to maintain our qualification for taxation as a REIT, or purchase the partner's interests or assets at an above-market price;
our joint venture partners may take actions unrelated to our business agreement but which reflect poorly on us because of our joint venture;
disputes between us and our partners may result in litigation or arbitration that would increase our expenses and prevent our management from focusing their time and effort on our day-to-day business; and
we may in certain circumstances be liable for the actions of our third-party partners or guarantee all or a portion of the joint venture's liabilities, which may require us to pay an amount greater than its investment in the joint venture.

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

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, 2021, 2020 and 2019, we recognized approximately 61%, 59% and 58%, respectively, of our revenues outside the U.S. We currently operate outside of the U.S. in Canada, Mexico, South America, Asia-Pacific, and EMEA.

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 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:

30

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 withdrawal from the European Union ("Brexit"), the Hong Kong national security law, and the current trade war between the U.S. and China;
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;
compliance with changing laws, policies, and requirements related to sustainability;
compliance with evolving governmental regulation with which we have little experience; and
compliance with evolving and varied regulations related to the ongoing COVID-19 pandemic and related vaccine mandates.

Geo-political events, such as the ongoing COVID-19 pandemic, Brexit, the Hong Kong national security law, the trade war between the U.S. and China and Russian and Ukraine tensions, may increase the likelihood of the listed risks to occur and could have a negative effect on our business domestically or internationally. 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 laws and 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. With respect to the current trade war between the U.S. and China, we have several customers in China named in restrictive executive orders by the previous U.S. administration that are currently covered by a freeze issued by the current U.S. administration or currently enjoined from enforcement subject to pending litigation. If Equinix is required to cease business with these companies, or additional companies in the future, our revenues could be adversely affected. Violations of any of these domestic or international 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 results of operations. Our success depends, in part, on our ability to anticipate and address these risks and manage these difficulties.

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 IBX data centers once they are built. In addition, unanticipated technological changes could affect customer requirements for data
31

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.

Risks Related to Our Capital Needs and Capital Strategy
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, 2021, our total indebtedness (gross of debt issuance cost, debt discount, and debt premium) was approximately $13.9 billion, our stockholders' equity was $10.9 billion and our cash and cash equivalents totaled $1.5 billion. In addition, as of December 31, 2021, we had approximately $1.9 billion of additional liquidity available to us from our $2.0 billion revolving credit facility. In addition to our substantial debt, we lease many of our IBX data centers and certain equipment under lease agreements, some of which are accounted for as operating leases. As of December 31, 2021, we recorded operating lease liabilities of $1.3 billion, which represents our obligation to make lease payments under those lease arrangements.
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, or of a downgrade to our current rating;
make it more difficult for us to satisfy our obligations under our various debt instruments;
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;
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.
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.
Sales or issuances of shares of our common stock may adversely affect the market price of our common stock.

Future sales or issuances of common stock or other equity related securities may adversely affect the market price of our common stock, including any shares of our common stock issued to finance capital expenditures, finance acquisitions or repay debt. In October 2020, we established an "at the market" equity offering program (the "2020 ATM Program") in the amount of $1.5 billion under which we may, from time to time, issue and sell shares of our common stock to or through sales agents up to established limits. As of December 31, 2021, we had $1.0 billion available for sale under the 2020 ATM Program. We expect to refresh our ATM program periodically, which could lead to additional dilution for our stockholders in the future. We may also seek authorization to sell additional shares
32

of common stock through other means which could lead to additional dilution for our stockholders. Please see Note 12 within the Consolidated Financial Statements of this Annual Report on Form 10-K for sales of our common stock under our ATM programs.

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 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 risks, refer to our discussion of foreign currency risk in "Quantitative and Qualitative Disclosures About Market 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.

Risks Related to Environmental Laws and Climate Change Impacts

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
33

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, permits or leases for the removal or cleanup of such substances or materials, the cost of which could be substantial.

We purchase significant amounts of electricity from generating facilities and utility companies that are subject to environmental laws, regulations and permit requirements. These environmental requirements are subject to material change, which could result in increases in our electricity suppliers' compliance costs that may be passed through to us. Regulations promulgated by the U.S. EPA or state agencies, or by regulators in other countries, could limit air emissions from fossil fuel-fired power plants, restrict discharges of cooling water, and otherwise impose new operational restraints on conventional power plants that could increase costs of electricity. Regulatory programs intended to promote increased generation of electricity from renewable sources may also increase our costs of procuring 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 environmental regulations do not normally impose material costs upon our operations, unexpected events, equipment malfunctions, human error and changes in law or regulations, among other factors, can lead to additional capital requirements, limitations upon our operations and unexpected increased costs.

Regulation of 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, by requiring capture, management or reduction of GHG emissions, or by imposing taxes or fees upon electricity generation or use. There has been interest in the U.S. Congress and in countries where we operate abroad in addressing climate change. In the U.S., we believe there is a likelihood that new regulations or legislation will be proposed and potentially enacted that would seek to limit carbon dioxide emissions and the use of fossil fuels. Past legislative proposals to address climate change have included measures ranging from "carbon taxes," to tax credits, to federally imposed limitations on GHG emissions. The course of future legislation and regulation in the U.S. and abroad remains difficult to predict and the potential increased costs associated with GHG regulation or taxes cannot be estimated at this time.

State regulations also have the potential to increase our costs of obtaining electricity. Certain U.S. states in which we operate have issued or are considering and may enact environmental regulations that could materially affect our facilities and electricity costs. For example, California has limited GHG emissions from new and existing conventional power plants by imposing regulatory caps and by auctioning the rights to emission 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 northeastern states adopted a multi-state program for limiting carbon emissions through the Regional Greenhouse Gas Initiative ("RGGI") cap and trade program. Other countries in which we operate may impose requirements and restrictions similar to those imposed in the U.S. Environmental regulations have not had a material adverse effect on our electricity costs to date, but due to costs of changing pollution control technologies, potential new regulatory requirements and the market-driven nature of some of the programs, such regulations could have a material adverse effect on electricity costs in the future.

Aside from regulatory requirements, we have separately undertaken efforts to procure energy from renewable energy projects in order to support new renewables development. These efforts to support and enhance renewable electricity generation may increase our costs of electricity above those that would be incurred through procurement of conventional electricity from existing sources or through conventional grids.

Our business may be adversely affected by climate change and responses to it.

Severe weather events, such as droughts, fires, flooding, heat waves, hurricanes, typhoons and other winter storms, pose a threat to our IBX data centers and our customers' IT infrastructure through physical damage to facilities or equipment, power supply disruption, and long-term effects on the cost of electricity. The frequency and intensity of severe weather events are reportedly increasing as part of broader climate changes. Changes in global weather patterns may also pose long-term risks of physical impacts to our business.

We maintain disaster recovery and business continuity plans that would be implemented in the event of severe weather events that interrupt our business or affect our customers' IT infrastructure housed in our IBX data centers. While these plans are designed to allow us to recover from natural disasters or other events that can interrupt our business, we cannot be certain that our plans will work as intended, facilitating our response to such disasters or events. Failure to prevent impact to customers from such events could adversely affect our business.

U.S. and global environmental regulations are expected to continue to change and evolve and may impose upon us new or unexpected costs. Concern about climate change in various jurisdictions may result in more stringent laws and regulatory requirements regarding emissions of carbon dioxide or other GHGs. Restrictions on carbon dioxide or other GHG emissions could result in significant increases in operating or capital costs, including higher energy costs generally, and increased costs from carbon taxes, emission cap and trade programs and renewable portfolio standards that are imposed upon our electricity suppliers. These higher energy costs, and the cost of complying across our global platform, or of failing to comply with these and any other climate change regulations, may have an adverse effect on our business and our results of operations.

We may fail to achieve our environmental change goals which may adversely affect public perception of our business and affect our relationship with our customers and/or our stockholders.

We have prioritized sustainability and have established long term goals of using 100% clean and renewable energy and reducing our GHG emissions from our operations and supply chain. We also face pressure from our customers and stockholders, who are increasingly focused on climate change, to prioritize renewable energy procurement, reduce our carbon footprint and promote sustainable practices. To address these goals and concerns, where possible, we plan to continue to scale our renewable energy strategy, seek low-carbon alternatives for traditional fuel sources and refrigerants, and pursue opportunities to improve energy and water efficiency. As a result of these and other initiatives, we intend to make progress towards reducing our environmental impact and global carbon footprint, as well as ensuring our business remains viable in a low-carbon economy. It is possible, however, that we may fail to reach our stated environmental goals in a timely manner or that our customers and stockholders might not be satisfied with our sustainability efforts or the speed of their adoption. A failure to meet our goals could adversely affect public perception of our business, employee morale or customer or stockholder support. If we do not meet our customers' or stockholders' expectations, our business and/or our share price could be harmed.

Risks Related to Certain Regulations and Laws, Including Tax Laws

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 and other 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 and other taxes. 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 changes to the tax laws and interpretations thereof. For example, we are currently undergoing audits and appealing the tentative assessments in a number of jurisdictions where we operate. The final results of these audits and the outcomes of the appeals are uncertain and may not be resolved in our favor. Additionally, the U.S. Congress and the current presidential administration of the U.S. have proposed various changes to federal income tax laws, including a potential minimum tax as well as changes to the laws governing the U.S. taxation of foreign earned income under the GILTI (Global Intangible Low Taxed Income) rules. It is unclear whether REITs might be exempt from the final legislation. Changes in tax laws, including the addition of a minimum tax threshold and to the GILTI rules, could have a material adverse effect on our tax liability and increase our REIT dividend distribution meaningfully.

The Organisation for Economic Co-operation and Development ("OECD") is an international association made up of over 30 countries including the U.S. The OECD has proposed and made numerous changes to long-standing tax principles, which, if adopted by the member countries, could have a materially adverse effect on our tax liabilities. For example, various jurisdictions are starting to explore the taxation of digital service and the minimum effective tax rate Model Rules through the adoption of tax principles which could have a negative effect on our tax liability.

35

The ongoing COVID-19 pandemic has led to increased spending by many governments. Because of this, there could be pressure to increase taxes in the future to pay back debts and generate revenues. The nature and timing of any future changes to each jurisdiction's tax laws and the impact on our future tax liabilities because of the COVID-19 pandemic or for any other reason cannot be predicted with any accuracy but could materially and adversely impact our results of operations and financial position or cash flows.

Government regulation or failure to comply with laws and regulations may adversely affect our business.

Various laws and governmental regulations, both in the U.S. and abroad, governing internet-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 overturned network neutrality rules, which may result in material changes in the regulations and contribution regime affecting us and our customers. Furthermore, the U.S. Congress and state legislatures are reviewing and considering changes to the new FCC rules making the future of network neutrality uncertain. Changes to these laws and regulations could have a material adverse effect on us and our customers. There may also be forthcoming regulation in the U.S. on a federal or state level in the areas of cybersecurity, data privacy, taxation and data security, any of which could impact us and our customers. Similarly, data privacy regulations continue to evolve and must be addressed by Equinix as a global company.

We 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, competition and antitrust, and taxation apply to our business and those which might have a material effect on our customers’ decisions to purchase our services and solutions. 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 internet 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.

While our business and IBX data centers are currently all operational and have been designated "critical infrastructure" or "essential services" in order to remain open in many jurisdictions during the ongoing COVID-19 pandemic, any regulations restricting our ability to operate our business due to the COVID-19 pandemic could have a material adverse effect on our business. Additionally, the "essential services" and "critical infrastructure" designations we have experienced could lead countries or local regulators to impose additional regulations on the data center industry due to the COVID-19 pandemic in order to have better visibility and control over our industry for future events.

We strive to comply with all laws and regulations that apply to our business. However, as these laws evolve, they can be subject to varying interpretations and regulatory discretion. To the extent a regulator or court disagrees with our interpretation of these laws and determines that our practices are not in compliance with applicable laws and regulations, we could be subject to civil and criminal penalties that could adversely affect our business operations. The adoption, or modification of laws or regulations relating to the internet and our business, or interpretations of existing laws, could have a material adverse effect on our business, financial condition and results of operations.

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.

36

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 U.S. 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 every quarter of 20192021 and have declared a quarterly distribution to be paid on March 18, 2020.23, 2022. 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 Annual Report on 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
37

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 qualification for taxation as a REIT. 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 generally 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 dohave not currently intendmade such an election to do so.date. 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 40 years.

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

Our ability to receive distributions from our TRSs is limited by the rules with which we must comply to maintain our qualification for taxation as a REIT. In particular, at least 75% of our gross income for each taxable year as a REIT must be derived from real estate. 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
38

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, including taxes on any undistributed income, and state, local or foreign income, franchise, property and transfer taxes. In addition, we could in certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in respect of dealer property income or 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 U.S. 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 an asset that we or our qualified REIT subsidiaries ("QRSs")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, 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 tomay be treated as nonqualifying income for purposes of the REIT gross income tests. As a result of these rules, we may needhave from time to limittime limited our use of advantageous hedging techniques or implementhave implemented those hedges through our TRSs, which we presently do.and our future hedging strategies may continue to be so affected. 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
39

possible use against future income or gain in the TRSs. As a result, our financial performance, including our AFFO,adjusted funds from operations ("AFFO"), may also fluctuate.

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 before 2026, REIT dividends paid to noncorporate stockholders that meet specified holding period requirements are generally taxed at an effective tax rate lower than applicable ordinary income tax rates due to the availability of a deduction under the Code for specified forms of income from passthrough entities. More favorable rates will nevertheless continue to apply to regular corporate "qualified" dividends, which may cause some investors to perceive that an investment in a REIT is less attractive than an investment in a non-REIT entity that pays dividends, thereby reducing the demand and market price of our common stock.

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. 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, theU.S. federal or state income tax laws governing REITs, or the administrative interpretations of those laws, or local laws impacting our REIT structure for our international operations, may be amended. FederalU.S. federal, state and statelocal 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 and local taxing authorities. Changes to the tax laws, regulations and administrative interpretations or local laws governing our international operations, which may have retroactive application, could adversely affect us. In addition, some of these changes could have a more significant impact on us as compared to other REITs due to the nature of our business and our substantial use of TRSs, particularly non-U.S. TRSs.


40

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.

General Risk Factors

Adverse global economic conditions, like the ones we are currently experiencing, could adversely impact our business and financial condition.

Adverse global economic conditions like the ones we are currently experiencing because of global inflation, the increased cost of power, and supply chain issues have created, and in the future may increase, risk to our financial outlook. We are experiencing these issues in various aspects of our business. As discussed above, our efforts to mitigate the risks associated with these global economic conditions may not be successful and our business and growth could be adversely affected.

The uncertain global economy could also result in material churn in our customer base, reductions in revenues from our offerings, adverse effects to our DSO, longer sales cycles, slower adoption of new technologies and increased price competition, which could adversely affect our liquidity. Customers and vendors filing for bankruptcy could also lead to costly and time-intensive actions with adverse effects, including greater difficulty or delay in accounts receivable collection. The uncertain economic environment could also have an impact on our foreign exchange forward contracts if our counterparties' credit deteriorates or if they are otherwise unable to perform their obligations. Finally, volatility in the financial markets like we are currently experiencing could affect our ability to access the capital markets at a time when we desire, 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.

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 recently been and may continue to be highly volatile. General economic and market conditions, like the instability due to the ongoing COVID-19 pandemic, and market conditions for telecommunications and REIT 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:

news or regulations regarding the ongoing COVID-19 pandemic;
our results of operations or forecasts;
new issuances of equity, debt or convertible debt by us, including issuances through our 2020 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;
changes in U.S. or foreign tax laws;
changes in management or key personnel;
developments in our relationships with customers;
announcements by our customers or competitors;
changes in regulatory policy or interpretation;
governmental investigations;
41

ITEM 1B.Unresolved Staff Comments
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's attention from other business concerns, which could seriously harm our business.

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.

The ongoing COVID-19 pandemic is expected to have a material effect on many aspects of the economy, but the extent of its impact on Equinix is difficult to predict at this time. We continue to evolve our forecasting models as the situation unfolds but if our predictions are inaccurate and our results differ materially from our forecasts, we could make inappropriate financial decisions. Additionally, inaccuracies in our models could adversely impact our compliance with REIT asset tests, future profitability, stock price and/or stockholder confidence.

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, 2020, 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 recently acquired businesses, 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.

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's attention and resources. Results cannot be predicted with certainty and an adverse outcome in litigation could result in monetary damages or injunctive relief. Further, any payments made in settlement may directly reduce our revenue under U.S. GAAP and could negatively impact our
42

results of operations 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.

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" 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.

ITEM 3.Legal Proceedings
The following is a description of reportable legal proceedings, including those involving governmental authorities under federal, state and local laws regulating the discharge of materials into the environment.may change based on final construction details.
In March 2019, charges were brought by the Public Prosecutor in Milan, Italy against Equinix (Italia) S.r.l. and Eric Schwartz, at that time one of the directors of Equinix (Italia) S.r.l., following the discovery of levels of copper in ground water in excess of those permitted by law and alleged to have been released by Equinix into the water supply. We
47



determined that the copper levels detected had been misinterpreted by the Public Prosecutor's office, which had multiplied the findings tenfold. On March 13, 2019, we asked for an initial extension to file our defense and requested that the charges against both Equinix and Mr. Schwartz be dropped on the grounds that the levels of copper found were in fact less than double the permitted amounts. The Public Prosecutor accepted that the number it originally used was incorrect, but did not agree to drop the charges and has requested a trial date. Our defense was filed April 15, 2019. A trial date has been set for March 6, 2020. The maximum fine for Equinix relating to this matter is €350,000 and the maximum personal fine for Mr. Schwartz is €30,000, which together give the maximum exposure of €380,000.ITEM 3.    Legal Proceedings
We have recently adopted a formal compliance program pursuant to Italian Legislative Decree No. 231/2001 ("Decree 231"), which we expect will reduce our exposure to fines and penalties in a Court verdict by 50%. After adoption of Decree 231, the exposure for Equinix would be effectively reduced to €175,000, giving a new maximum exposure of €205,000.None.
While it is not possible to accurately predict the final outcome of this pending Court proceeding, if it is decided adversely to Equinix, we expect there would be no material effect on our consolidated financial position. Nevertheless, this proceeding is reported pursuant to Securities and Exchange Commission regulations.

eqix-20211231_g11.jpg
We provide a global, vendor-neutral data center, interconnection and edge services platform with offerings that aim to enable our customers to reach everywhere, interconnect everyone and integrate everything. Global enterprises, service providers and business ecosystems of industry partners rely on our IBX data centers and expertise around the world for the safe housing of their critical IT equipment and to protect and connect the world's most valued information assets. They also look to Platform Equinix® for the ability to directly and securely
51

interconnect to the networks, clouds and content that enable today's information-driven global digital economy. Our recent IBX data center openings and acquisitions, as well as xScaleTM data center investments, have expanded our total global footprint to 240 data centers, including eight xScale data centers and the MC1 data center that were held in unconsolidated joint ventures, across 66 markets around the world. Metrics also include the MU4 and GN1 data centers which opened in January 2022. Equinix offers the following solutions:
premium data center colocation;
interconnection and data exchange solutions;
edge services for deploying networking, security and hardware; and
remote expert support and professional services.
Our interconnected data centers around the world allow our customers to increase information and application delivery performance to users, and quickly access distributed IT infrastructures and business and digital ecosystems, while significantly reducing costs. Our global platform and the quality of our IBX data centers, interconnection offerings and edge services have enabled us to establish a critical mass of customers. As more customers choose Platform Equinix for bandwidth cost and performance reasons, it benefits their suppliers and business partners to colocate in the same data centers. This adjacency creates a “network effect” that enables our customers to capture 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 interconnection that increases data traffic exchange while lowering overall cost and increasing flexibility. Our focused business model is built on our critical mass of enterprise and service provider customers and the resulting "marketplace" effect. This global platform, combined with our strong financial position, has driven new customer growth and bookings.
Historically, our market was served by large telecommunications carriers who bundled their products and services with their colocation offerings. The data center market landscape has evolved to include private and vendor-neutral multi-tenant data center ("MTDC") providers, hyperscale cloud providers, managed infrastructure and application hosting providers, and systems integrators. It is estimated that Equinix is one of more than 2,200 companies that provide MTDC offerings around the world. 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 27 countries with the industry’s largest and most active ecosystem of partners in our sites, proven operational reliability, improved application performance and a highly scalable set of offerings.
The cabinet utilization rate represents the percentage of cabinet space billed versus total cabinet capacity, which is used to measure how efficiently we are managing our cabinet capacity. Our cabinet utilization rate varies from market to market among our IBX data centers across our Americas, EMEA and Asia-Pacific regions. Our cabinet utilization rates were approximately 79%, as of December 31, 2021 and 2020. Excluding the impact of our IBX data center expansion projects that have opened during the last 12 months, our cabinet utilization rate would have increased to approximately 81% as of December 31, 2021. 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, results of operations and cash flows.
To serve the needs of the growing hyperscale data center market, including the world's largest cloud service providers, we have entered into joint ventures to develop and operate xScale data centers. In the past two years, we entered into our EMEA 1 Joint Venture, Asia-Pacific 1 Joint Venture and EMEA 2 Joint Venture, and entered into negotiations in connection with a new joint venture (the "AMER 1 Joint Venture"), in the form of limited liability partnerships with GIC, Singapore's sovereign wealth fund ("GIC"). In October 2021, we entered into an agreement to form an additional joint venture in the form of a limited liability partnership with PGIM Real Estate, to further expand our xScale data center portfolio in Asia-Pacific (the "Asia-Pacific 2 Joint Venture"). See Note 5 within the Consolidated Financial Statements.

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, clouds and software partners, capacity availability in the current market location, amount of incremental investment required by us in the targeted property, automation capabilities, developer talent pool, 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 our 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.
Revenue:
eqix-20211231_g12.jpg
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 the past three years, more than 80% 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, 2021, 2020 and 2019. Our 50 largest customers accounted for approximately 39% of our recurring revenues for the years ended December 31, 2021, 2020 and 2019.
Our non-recurring revenues are primarily comprised of installation services related to a customer's initial deployment and professional services we perform, as well as equipment sales. 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 the 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.
Operating Expenses:
Cost of Revenues. 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. 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
53

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. Our costs of electricity may also increase as a result of the physical effects of climate change, increased regulations driving alternative electricity generation due to environmental considerations or as a result of our election to use renewable energy sources. To the extent we incur increased utility costs, such increased costs could materially impact our financial condition, results of operations and cash flows.
Sales and Marketing. Our 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. Our 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 on back office systems.
Taxation as a REIT
We elected to be taxed as a REIT for U.S. federal income tax purposes beginning with our 2015 taxable year. As of December 31, 2021, our REIT structure included all of our data center operations in the U.S., Canada (with the exception of one data center in Montreal), Mexico, Japan, Singapore and the majority of our data centers in EMEA. Our data center operations in other jurisdictions are operated as TRSs. We included our share of the assets in the EMEA and Asia-Pacific Joint Ventures in our REIT structure.
As a REIT, we generally are permitted to deduct from our U.S. federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to U.S. federal income taxes 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 to U.S. federal and state corporate income taxes, as applicable. Likewise, our foreign subsidiaries continue to be subject to local 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 U.S. federal 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 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 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, should we have net income from "prohibited transactions," we will be subject to tax on this income at a 100% rate. "Prohibited transactions," for this purpose, are defined as dispositions, at a gain, of inventory or property held primarily for sale to customers in the ordinary course of a trade or business other than dispositions of foreclosure property and other than dispositions excepted by statutory safe harbors. If we fail to remain qualified for U.S. federal income taxation as a REIT, we will be subject to U.S. federal income taxes at regular corporate income tax rates. Even if we remain qualified for U.S. federal income 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 U.S. federal income tax regime for REITs, many states do not completely follow federal rules, and some may not follow them at all.
We continue to monitor our REIT compliance in order to maintain our qualification for U.S. federal income taxation 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.
On each of March 17, June 16, September 22, and December 15, 2021 we paid quarterly cash dividends of $2.87 per share. We expect the amount of our applicable dividends and other applicable distributions to equal or exceed the REIT taxable income that we recognized in 2021.
The Impact of the ongoing COVID-19 pandemic on Our Results and Operations
We have continued to closely monitor the impact of the COVID-19 pandemic on our people and business. All of our IBX data centers have remained, and continue to remain, operational at the time of filing of this Annual Report on Form 10-K. We have begun a phased plan for return-to-office for most of our non-IBX attached sites on a voluntary basis in accordance with guidance provided by government agencies. Non-essential business travel
54

remains limited, and while we continue to hold virtual events, we have also resumed certain in-person events as local travel restrictions allow.
While we are experiencing some construction delays, including those due to supply chain impacts from the COVID-19 pandemic, to date, the construction delays and additional costs are insignificant relative to the overall project duration and budget. We have not observed any significant disruption to our IBX data center operations. 
During the years ended December 31, 2021 and 2020, the COVID-19 pandemic did not have a material impact on our results of operations. We incurred one-time cash bonuses and compensation expense of $8.6 million for our IBX employees as well as other employees to support their work-from-home requirements during the first quarter of 2020. We have also experienced some travel expense savings during the years ended December 31, 2021 and 2020 resulting from travel restrictions imposed in response to the COVID-19 pandemic.
Looking ahead, the full impact of the ongoing COVID-19 pandemic on our future financial condition or results of operations remains uncertain and will depend on a number of factors, including the duration and potential cyclicity of the health crisis and further public policy actions to be taken in response, as well as the continued impact of the pandemic on the global economy and our customers and vendors. Our past results may not be indicative of our future performance and historical trends may differ materially.
For additional details regarding the risks to our business from the ongoing COVID-19 pandemic, refer to Part I, Item 1A. Risk Factors included elsewhere in this Annual Report on Form 10-K.
2021 Highlights:
In March, we issued €1.1 billion in Senior Notes due 2027 and 2033, or approximately $1.3 billion in U.S. dollars, at the exchange rate in effect on March 10, 2021. Using a portion of the proceeds, we redeemed all of the remaining outstanding 2.875% Euro Senior Notes due 2026 for approximately $590.7 million in U.S. dollars, at the exchange rate in effect on March 24, 2021. See Note 11 within the Consolidated Financial Statements.
In May, we issued $2.6 billion in Senior Notes due 2026, 2028, 2031 and 2052. Using a portion of the proceeds, we repaid approximately $659.9 million of term loans and redeemed all of our outstanding $1.25 billion 5.375% Senior Notes due 2027. See Note 11 within the Consolidated Financial Statements.
In May, we sold 137,604 shares under our 2020 "at-the-market" stock offering program (the "2020 ATM Program") for approximately $99.6 million in proceeds, net of payment of commissions to sales agents and other offering expenses. See Note 12 within the Consolidated Financial Statements.
In June, we entered into an agreement to form another joint venture in the form of a limited liability partnership with GIC, to develop and operate additional xScaleTM data centers in Europe and the Americas (the “EMEA 2 Joint Venture”). The transaction is structured to close in phases over the course of two years, pending regulatory approval and other closing conditions. Upon closing of the first phase of the transaction in September 2021, GIC contributed cash in exchange for an 80% partnership interest in the EMEA 2 Joint Venture and we sold certain data center sites and facilities located in Frankfurt, Helsinki, Madrid, Milan and Paris to the EMEA 2 Joint Venture in exchange for a total consideration of $144.0 million, including a 20% partnership interest in the JV. See Note 5 within the Consolidated Financial Statements.
In September, we completed the acquisition of two data centers in Mumbai, India from GPX Global Systems, Inc. ("GPX India") for a total purchase consideration of approximately $170.5 million. See Note 3 within the Consolidated Financial Statements.
In October, we entered into an agreement to form a joint venture in the form of a limited liability partnership with PGIM Real Estate ("PGIM"), to develop and operate xScale data centers in Asia-Pacific (the "Asia-Pacific 2 Joint Venture"). Upon closing, PGIM will contribute cash in exchange for an 80% partnership interest in the Asia-Pacific 2 Joint Venture. We agreed to sell the Sydney 9 ("SY9") data center site in exchange for a 20% partnership interest in the Asia-Pacific 2 Joint Venture and cash proceeds. The assets and liabilities of the SY9 data center, which are currently included within our Asia-Pacific region, were classified as held for sale as of September 30, 2021 and remained held for sale as of December 31, 2021. See Note 5 within the Consolidated Financial Statements.

In November and December, we sold a total of 500,013 shares under our 2020 ATM Program for approximately $398.4 million in proceeds, net of payment of commissions to sales agents and other offering expenses. See Note 12 within the Consolidated Financial Statements.
In December, we entered into an agreement to purchase MainOne Cable Company Ltd. ("MainOne") at an enterprise value of approximately $320 million in an all-cash transaction. The acquisition is expected to close in the second quarter of 2022, subject to customary conditions including regulatory approval. See Note 3 within the Consolidated Financial Statements.

Revenue:
picture2recurringa04.jpg
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 the past three years, more than 80% 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, 2019, 2018 and 2017. Our 50 largest customers accounted for approximately 39%, 38% and 37%, respectively, of our recurring revenues for the years ended December 31, 2019, 2018 and 2017.
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 the 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.
Operating Expenses:
Cost of Revenues. 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. 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 or other 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. Consolidated Financial Statements.

Our 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. Our 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 on back office systems.
Taxation as a REIT
We elected to be taxed as a REIT for U.S. federal income tax purposes beginning with our 2015 taxable year. As of December 31, 2019,2021, our REIT structure included all of our data center operations in the U.S., Canada (with the exception of one data center in Montreal), Mexico, Japan, Singapore and the majority of our data center operationscenters in EMEA with the exception of Bulgaria, the United Arab Emirates, and the data center operations outside Amsterdam in the Netherlands.EMEA. Our data center operations in other jurisdictions are operated as TRSs. We included our interestshare of the assets in the EMEA and Asia-Pacific Joint VentureVentures in our REIT structure.
As a REIT, we generally are permitted to deduct from our U.S. federal taxable income the dividends we pay to our stockholders. The income represented by such dividends is not subject to U.S. federal income taxes 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 to U.S. corporate federal and state corporate income taxes, as applicable. Likewise, our foreign subsidiaries continue to be subject to foreignlocal 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 U.S. federal 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 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 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, should we have net income from "prohibited transactions," we will be subject to tax on this income at a 100% rate. "Prohibited transactions," for this purpose, are defined as dispositions, at a gain, of inventory or property held primarily for sale to customers in the ordinary course of a trade or business other than dispositions of foreclosure property and other than dispositions excepted by statutory safe harbors. If we fail to remain qualified for U.S. federal income taxation as a REIT, we will be subject to U.S. federal income taxes at regular corporate income tax rates. Even if we remain qualified for U.S. federal income 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 U.S. federal income tax regime for REITs, many states do not completely follow federal rules, and some may not follow them at all.
We continue to monitor our REIT compliance in order to maintain our qualification for U.S. federal income taxation 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. We converted our data center operations in Singapore into the REIT structure effective September 30, 2019.
On each of March 20,17, June 19,16, September 18,22, and December 11, 2019,15, 2021 we paid quarterly cash dividends of $2.46$2.87 per share. We expect these quarterlythe amount of our applicable dividends and other applicable distributions to equal or exceed the REIT taxable income that we recognized in 2019.2021.
2019The Impact of the ongoing COVID-19 pandemic on Our Results and Operations
We have continued to closely monitor the impact of the COVID-19 pandemic on our people and business. All of our IBX data centers have remained, and continue to remain, operational at the time of filing of this Annual Report on Form 10-K. We have begun a phased plan for return-to-office for most of our non-IBX attached sites on a voluntary basis in accordance with guidance provided by government agencies. Non-essential business travel
54

remains limited, and while we continue to hold virtual events, we have also resumed certain in-person events as local travel restrictions allow.
While we are experiencing some construction delays, including those due to supply chain impacts from the COVID-19 pandemic, to date, the construction delays and additional costs are insignificant relative to the overall project duration and budget. We have not observed any significant disruption to our IBX data center operations. 
During the years ended December 31, 2021 and 2020, the COVID-19 pandemic did not have a material impact on our results of operations. We incurred one-time cash bonuses and compensation expense of $8.6 million for our IBX employees as well as other employees to support their work-from-home requirements during the first quarter of 2020. We have also experienced some travel expense savings during the years ended December 31, 2021 and 2020 resulting from travel restrictions imposed in response to the COVID-19 pandemic.
Looking ahead, the full impact of the ongoing COVID-19 pandemic on our future financial condition or results of operations remains uncertain and will depend on a number of factors, including the duration and potential cyclicity of the health crisis and further public policy actions to be taken in response, as well as the continued impact of the pandemic on the global economy and our customers and vendors. Our past results may not be indicative of our future performance and historical trends may differ materially.
For additional details regarding the risks to our business from the ongoing COVID-19 pandemic, refer to Part I, Item 1A. Risk Factors included elsewhere in this Annual Report on Form 10-K.

Asia-Pacific General and Administrative Expenses. During the year ended December 31, 2019,2021, Asia-Pacific general and administrative expenses increased by 8% (9%$46.1 million or 44% (41% on a constant currency basis). The increase in our Asia-Pacific general and administrative expense was primarily due to:

We also expect travel and entertainment expenses to increase as travel restrictions that were imposed in response to the COVID-19 pandemic are eased. Additionally, given that our corporate headquarters is located withinin the U.S., we expect the Americas general and administrative expenses as a percentage of revenues to be higher than ourthose of other regions.

Income Taxes. We operate as a REIT for U.S. federal income tax purposes. As a REIT, we are generally not subject to U.S. federal and state 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 tax years ended December 31, 20192021 and 2018,2020, respectively. As such, other than tax attributable to built-in-gains recognizedstate income taxes and foreign income and withholding taxes, no provision for U.S. federal income taxes has been included for the REIT and its QRSs has been included in the accompanying consolidated financial statements for the years ended December 31, 20192021 and 2018.2020.
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 may not be REIT compliant.
U.S. federal 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, 20192021 and 2018.2020.
For the years ended December 31, 20192021 and 2018,2020, we recorded $185.4$109.2 million and $67.7$146.2 million of income tax expenses, respectively. Our effective tax rates were 26.8%17.9% and 15.6%28.3%, respectively, for the years ended December 31, 20192021 and 2018.2020. The higherlower effective tax rate in 20192021 as compared to 20182020 is primarily due to a releasethe reversal of valuation allowanceuncertain tax positions of $69.8 million resulting from the settlements of various tax audits in 2018 as a resultthe United Kingdom ("UK"), Germany, and Australia, partially offset by $12.3 million resulting from the revaluation of a legal entity reorganizationour deferred tax liabilities in our Americas region.the EMEA region due to the UK corporate tax rate increase from 19% to 25% and the Dutch corporate tax rate increase from 25% to 25.8% enacted in the current period.
Of the unrecognized tax benefits being realized in the year ended December 31, 2021, approximately $32.0 million is related to the uncertain tax position inherited from the Metronode Acquisition in 2018. The uncertain tax position was covered by an indemnification agreement with the Seller. The realization of the unrecognized tax benefits resulted in an impairment of the indemnification asset for the same amount, which has been included in Other Income (Expense) on the Consolidated Statements of Operations for the year ended December 31, 2021.
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 excluding depreciation, amortization, accretion, stock-based compensation expense, restructuring charges, impairment charges, transaction 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, 20192021 and 20182020 was split among the following geographic regions (dollars in thousands):

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 of operations 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 of operations when evaluating our operations.

Table of Contents
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 of operations 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 generally 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 transaction costs from AFFO and adjusted EBITDA to allow more comparable comparisons of our financial results to our historical operations. The transaction costs relate to costs we incur in connection with business combinations and the formation of joint ventures, including advisory, legal, accounting, valuation, and other professional or consulting fees. Such charges generally are not relevant to assessing theour long-term performance of the company.performance. In addition, the frequency and amount of such charges vary significantly based on the size and timing of the transactions. Management believes items such as restructuring charges, impairment charges, gain or loss on asset sales and transaction 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 improvedour steady operating results, as 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, as 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.
65

Table of Contents
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, transaction 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, net income (loss) from discontinued operations, net of tax, and adjustments

from FFO to AFFO for unconsolidated joint ventures' and noncontrolling interests' share of these items. 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.

(1)Impairment charges for 2021 relate to the impairment of an indemnification asset in Q2 2021 resulting from the settlement of a pre-acquisition uncertain tax position, which was recorded as Other Income (Expense) on the Consolidated Statements of Operations. This impairment charge was offset by the recognition of tax benefits in the same amount, which was included within the Income tax expense (benefit) adjustment line on the table above.

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. During the year ended December 31, 20192021 as compared to the same period in 2018,2020, the U.S. dollar was stronger relative to the Brazilian real Euro, British Pound, Singapore dollar and Australian dollar,Japanese yen, which resulted in an unfavorable foreign currency impact on revenue, operating income and adjusted EBITDA, and a favorable foreign currency impact on operating expenses. During the year ended December 31, 2021 as compared to the same period in 2020, the U.S. dollar was weaker relative to the Australian dollar, British Pound, Euro and Singapore dollar, which resulted in a favorable foreign currency impact on revenue, operating income and adjusted EBITDA, and an unfavorable foreign currency impact on operating expenses. 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. Our constant currency presentation excludes the impact of our foreign currency cash flow hedging activities. 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.results of operations. To present this information, our current 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, 20182020 are used as exchange rates for the year ended December 31, 20192021 when comparing the year ended December 31, 20192021 with the year ended December 31, 2018)2020).
Liquidity and Capital Resources
Sources and Uses of Cash
Customer collections are our primary source of cash. We believe we have a strong customer base, and have continued to experience relatively strong collections. As of December 31, 2019,2021, our total indebtedness was comprisedprinciple sources of debt and lease obligations totaling approximately $11.9liquidity were $1.5 billion (gross of debt issuance cost, debt discount, plus mortgage premium) consisting of:
approximately $9,029.2 million of principal from our senior notes;
approximately $1,506.1 million from our finance lease liabilities; and
$1,371.9 million of principal from our loans payable and mortgage.
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 distributions and completion of our publicly-announced expansion projects.
During 2019, we completed the following significant financing activities:
issued $2,800.0 million in Senior Notes due 2024, 2026 and 2029;
redeemed $1,906.3 million of Senior Notes due 2022, 2023 and 2025;
repaid $300.0 million of 5.0% Infomart Senior Notes according to their repayment terms;
issued and sold 2,985,575 shares of common stock in a public equity offering and received net proceeds of approximately $1,213.4 million, net of underwriting discounts, commissions and offering expenses; and
issued and sold 903,555 shares of common stock under our ATM Program, for proceeds of approximately $447.5 million, net of payment of commissions to sales agents and other offering expenses.
As of December 31, 2019, we had $1,879.9 million of cash, cash equivalents and short-term investments, of which approximately $1,456.8 million was held in the U.S.investments. In addition to our cash and investment portfolio, we had $1.9 billion of additional liquidity available to us from our $2.0 billion revolving facility and $300.0 milliongeneral access to both public and private debt and the equity capital markets. We also have additional liquidity available to us from our ATM program, under which we may offer and sell from time to time our common stock in "at the market" transactions. As of shares issuanceDecember 31, 2021, we had $1.0 billion available for sale under ourthe 2020 ATM Program.
Besides any further financing activity we may pursue, customer collections are our primary source of cash. While weWe believe we have a strong customer base,sufficient cash, coupled with anticipated cash generated from operating activities and have continuedexternal financing sources, to experience relatively strong collections, ifmeet our operating requirements, including repayment of the current market conditions were to deteriorate, someportion of our customers may have difficulty payingdebt as it becomes due, distribution of dividends and completion of our publicly-announced acquisitions, ordinary costs to operate the business, and expansion projects. We also believe that our financial resources will allow us and we may experience increased churn into manage future possible impacts of the ongoing COVID-19 pandemic on our customer base, includingbusiness operations for the foreseeable future, which could include reductions in their commitmentsrevenue and delays in payments from customers and partners.
As we continue to us, all of which could have a material adverse effect on our liquidity. Additionally,grow, 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 and joint ventures. WhileIf the opportunity to expand is greater than planned we expectmay further increase the level of capital expenditure to fund these plans with our existing resources,support this growth as well as pursue additional financing, either debtbusiness and real estate acquisitions or equity, may be required, and if current market conditions were to deteriorate,joint ventures provided that we

may be unable to secure additional financing, have or any such additional financing may only be available to us on unfavorable terms. An inabilitycan access sufficient funding to pursue additionalsuch expansion opportunitiesopportunities. We may elect to access the equity or debt markets from time to time opportunistically, particularly if financing is available on attractive terms. We will have a material adverse effect oncontinue to evaluate our abilityoperating requirements and financial resources in light of future developments, including those relating to maintain our desired levelthe ongoing COVID-19 pandemic.

Operating Activities
Our cash provided by our operations is generated by colocation, interconnection, managed infrastructure and other revenues. Our primary uses of cash from our operating activities include compensation and related costs, interest payments, other general corporate expenditures and taxes. The increase in netNet cash provided by operating activities increased by $237.4 million during 2019the year ended December 31, 2021 as compared to 2018 wasDecember 31, 2020, primarily due todriven by improved operating results combined with the inclusion of full year operating results of the acquisitions of Infomart Dallas and Metronode closed in April 2018,operations partially offset by increases in cash paid for cost of revenues,costs and operating expenses, interest expense and income taxes.expenses.
Investing Activities
The decrease in netNet cash used in investing activities decreased by $420.2 million during 2019the year ended December 31, 2021 as compared to 2018 wasDecember 31, 2020, primarily due to $1.0 billion less spent on business acquisitions, which consisted of the Bell, Packet and Axtel acquisitions in 2020 and the GPX acquisition in 2021 and a $20.2 million decrease in spending for business acquisitionspurchases of approximately $795.5investments. This decrease was partially offset by a $469.0 million primarily dueincrease in capital expenditures as a result of our expansion activity, a $125.8 million decrease in the proceeds from the sale of assets to the Metronodeour Joint Ventures and Infomart Dallas acquisitions in 2018 combined with an increasea $25.3 million decrease in proceeds from asset sales of approximately $346.6 million, primarily due to the sale of xScale data center facilities in connection with the closing of the Joint Venture.
During 2020, we anticipate our IBX expansion construction activity will increase from our 2019 levels. If 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 expenditure to support this growth as well as pursue additional business and real estate acquisitions or joint ventures.investments.
Financing Activities
Net cash provided by financing activities during 2019 wasdecreased by $401.8 million for the year ended December 31, 2021 as compared to December 31, 2020, primarily due to:

In connection with certain of our leases and other contracts requiring deposits, we entered into 41 irrevocable letters of credit totaling $84.0 million under the revolving credit facility. These letters of credit were provided in lieu of cash 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 $132.2 million as of December 31, 2019. 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, 2019, we were contractually committed for $795.0 million$1.0 billion of unaccrued capital expenditures,expenditure contractual commitments, primarily for IBX equipment not yet delivered and labor not

Additionally, we entered into lease agreements with various landlords primarily for data center spaces and ground leases which have not yet commenced as of December 31, 2019. These leases will commence between fiscal years 2020 and 2022, with lease terms of 10 to 49 years and total lease commitments of approximately $608.1 million, which are not reflected in the table above.
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, 2019, there were no significant liabilities recorded for these arrangements.2021. For additional information, see "Guarantor Arrangements"“Maturities of Lease Liabilities” in Note 1510 within the Consolidated Financial Statements.
Concurrent with the closing of the Joint Venture, the Joint Venture entered into a credit agreement with a group of lenders for secured credit facilities of €850.0 million, or $953.7 million in total at the exchange rate in effect on December 31, 2019, consisting of two secured term loan facilities and a secured revolving credit facility. The Joint Venture’s debt is secured by net assets of the Joint Venture, is without recourse to the partners, and does not represent a liability of the partners. We do not provide any guarantees to make principle payment to the lenders for the Joint Ventures’ indebtedness. Under the Joint Venture agreement, we and our joint venture partner GIC are also required to make additional equity contribution proportionately to the Joint Venture upon situations such as interest shortfall, cost-overrun or capital shortfall to complete certain construction phases.
Critical Accounting Policies and Estimates
Our consolidated financial statements are prepared in accordance with U.S. 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;goodwill and other intangible assets;
•    Accounting for property, plant and equipment; and
•    Accounting for leases.

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, andas well as tax attributes such as operating loss, capital 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's widely understood administrative practices and precedents. The Company recognizesWe recognize interest and penalties related to unrecognized tax benefits within income tax benefit (expense) in the consolidated statements of operations.


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 tax consequences.

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, 3) taxable income in carryback years permitted by the tax law, and 3)4) 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 a 50% likelylikelihood 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 significant assumptions used to estimate the fair market value of assets in QRSs and TRSs include projected revenue growth, projected operating margins and projected capital expenditure. We revisit significant assumptions periodically to reflect any changes due to business or economic environment.



As of December 31, 20192021 and 2018,2020, we had net total deferred tax liabilities of $211.4$280.5 million and $189.6$224.0 million, respectively. As of December 31, 20192021 and 2018,2020, we had a total valuation allowance of $57.8$100.7 million and $57.0$82.3 million, respectively. If and when we increase or reduce our remaining valuation allowances, it may have aan unfavorable or favorable impact, respectively, 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 jurisdiction, in the future.

During the year ended December 31, 2019,2021, we released theestablished full valuation allowances against the deferred tax assets of one of our BrazilianHong Kong legal entities due to the evidence of achieving sustainable profitability. For the Metronode Acquisition, we increased the valuation allowance that was assessed in prior year as a result of finalizing the provisional estimates related to the realizability of certain deferred tax assets.

During the year ended December 31, 2018, we released the full or partial valuation allowances against the deferred tax assets in certain jurisdictions in the Americas, Asia-Pacific and EMEA regions. As part of the purchase accounting determination for the Metronode Acquisition, we provided full valuation allowance againstwell as certain deferred tax assets acquired in AustraliaIndia and Canada that are not expected to be realizable in the foreseeable future.
During the year ended December 31, 2020, we provided full valuation allowances against certain deferred tax assets acquired in Canada and the Netherlands that are not expected to be realizable in the foreseeable future.


As of December 31, 20192021 and 2018,2020, we had unrecognized tax benefits of $173.7$148.3 million and $150.9$207.8 million, respectively, exclusive of interest and penalties. During the year ended December 31, 2019,2021, the unrecognized tax benefit decreased by $59.5 million primarily due to the settlements of various tax audits in the UK, Germany, and Australia, which was partially offset by the integrations in the EMEA region. During the year ended December 31, 2020, the unrecognized tax benefit increased by $22.8$34.1 million primarily due to integrations in the EMEA region, which was partially offset by the recognition of unrecognized tax benefits related to the Company’sour tax positions in Francea few countries as a result of a lapse in statutes of limitations and the partial payment of the Metronode pre-acquisition tax audit assessment which was fully indemnified by the seller. During the year ended December 31, 2018, the unrecognized tax benefits increased by $68.5 million primarily duerelated to the Metronode Acquisition and the reorganization of the Spanish entities from the Itconic acquisition.UK integration. The unrecognized tax benefits of $173.7$148.3 million as of December 31, 2019,2021, of which $3.4 million is subject to an indemnification agreement, if subsequently recognized, will affect our effective tax rate favorably at the time when such a benefit is recognized, of which $30.8 million is subject to an indemnification agreement.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 of identifiable intangible assets such as customer contracts, leases and any other significant assets or liabilities and contingent 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'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 a number of business combinations, including the acquisition of GPX in India in the third quarter of 2021, Bell Data Centers in Canada in the fourth quarter of 2020, Packet in March 2020, Axtel in Mexico in January 2020, and Switch Datacenters' AMS1 data center business in Amsterdam, Netherlands in April 2019, the Metronode Acquisition and the Infomart Dallas Acquisition in April 2018, the Itconic Acquisition and the Zenium data center acquisition in October 2017, the Verizon Data Center Acquisition in May 2017, and the IO Acquisition in February 2017.2019. The purchase price allocation for these acquisitions has been finalized.finalized, except for the GPX India acquisition.

As of December 31, 20192021 and 2018,2020, we had net intangible assets of $2.1$1.9 billion and $2.3$2.2 billion, respectively. We recorded amortization expense for intangible assets of $196.3$205.5 million, $203.4$199.0 million and $177.0$196.3 million for the years ended December 31, 2019, 20182021, 2020 and 2017,2019, 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 20192021 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.
 
We complete the annual goodwill impairment assessment for the Americas, EMEA and Asia-Pacific reporting units to determine if the fair values of the reporting units exceeded their carrying values.
 
We perform 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.




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 value. This analysis requires assumptions and estimates before performing the quantitative 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. Additionally, we periodically review our assessment of our reporting units to determine if changes in facts and circumstances warrant changes to our conclusions. There were no specific factors present in 20192021 or 20182020 that indicated a potential goodwill impairment.


We performed our annual review of other intangible assets by assessing if there were events or changes in circumstances indicating 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, a significant adverse change in legal factors or business climate that could affect the value of an asset or a continuous deterioration of our financial condition. This 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 events in 20192021 or 20182020 that indicated a potential impairment.



As of December 31, 2019,2021, goodwill attributable to the Americas, the EMEA and the Asia-Pacific reporting units was $1.7$2.2 billion, $2.4$2.5 billion and $0.6$0.7 billion, 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, 20192021 and 20182020 was $2.1$1.9 billion and $2.3$2.2 billion, respectively. 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. 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, 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.



Judgments are required in arriving at the estimated useful life of an asset and changes to these estimates would have 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. In 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.

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.



As of December 31, 20192021 and 2018,2020, we had property, plant and equipment of $12.2$15.4 billion and $11.0$14.5 billion, respectively. During the years ended December 31, 2019, 20182021, 2020 and 2017,2019, we recorded depreciation expense of $1.1$1.5 billion, $1.0$1.2 billion, and $0.9$1.1 billion, 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, 2019, 20182021, 2020 and 2017.2019. Further changes in our estimated useful lives of our property, plant and equipment could have a significant impact on our results of operations.

Accounting for Leases

A significant portion of our data center spaces, office spaces and equipment are leased. Each time we enter into a new lease or lease amendments, we analyze each lease or lease amendment for the proper accounting, including determining if an arrangement is or contains a lease at inception and making assessment of the leased properties to determine if they are operating or finance leases.



Determination of accounting treatment, including the result of the lease classification test for each new lease or lease amendment, is dependent on a variety of judgments, such as identification of lease and non-lease components, allocation of total consideration between lease and non-lease components, determination of lease term, including assessing the likelihood of lease renewals, valuation of leased property, and establishing the incremental borrowing rate to calculate the present value of the minimum lease payment for the lease test. The judgments used in the accounting for leases are inherently subjective; different assumptions or estimates could result in different accounting treatment for a lease.


Lease assumptions and estimates are determined and applied at the inception of the leases or at the lease modification date. As of December 31, 2019, we recorded2021 and 2020, operating right-of-use ("ROU") lease right-of-use assets ofwere at $1.3 billion and $1.5 billion, finance lease assets of $1.3 billion,respectively, and operating lease liabilities ofwere at $1.3 billion and $1.5 billion respectively . As of December 31, 2021 and 2020, finance ROU assets were $1.9 billion and $1.7 billion, respectively, and finance lease liabilities of $1.5 billion.
Additionally, duringwere $2.1 billion and $1.9 billion, respectively. For the years ended December 31, 2021, 2020 and 2019, 2018we recorded the finance lease cost of $275.0 million, $233.9 million and 2017, we$193.6 million , respectively, and recorded rent expense of approximately $221.8 million, $217.3 million and $219.0 million, $185.4 million and $157.9 million respectively.

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.
The uncertainty that exists with respect to the economic impact of the ongoing COVID-19 pandemic introduced significant volatility in the financial markets. See Part I, Item 1A. Risk Factors for additional information regarding potential risks to our business, financial condition and results of operations related to the ongoing COVID-19 pandemic.
We employ foreign currency forward and option contracts, cross-currency interest rate swaps and interest rate locks for the purpose of hedging certain specifically-identifiedspecifically identified exposures. The use of these financial instruments is intended to mitigate some of the risks associated with fluctuations in currency exchange and interest 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 recorded on our consolidated balance sheets at fair value with changes in fair values recognized in net 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, 2019.2021.
As of December 31, 2019,2021, our investment portfolio of cash equivalents and marketable securities consisted of money market funds, certificates of deposits and publicly traded equity securities. The amount in our investment portfolio that could be susceptible to market risk totaled $896.9$585.7 million.
Interest Rate Risk 
We are exposed to interest rate risk related to our outstanding debt. An immediate 10% increase or decrease in current interest rates from their position as of December 31, 20192021 would not have a material impact on our interest expense due to the fixed coupon rate on the majority of our debt obligations. However, the interest expense associated with our senior credit facility and term loans that bear interest at variable rates could be affected. For every 100 basis100-basis point changeincrease or decrease in interest rates, our annual interest expense could increase by a total of approximately $11.5$5.5 million or decrease by a total of approximately $4.8$1.4 million based on the total balance of our primaryterm loan borrowings under the Term Loan Facility as of December 31, 2019.2021. As of December 31, 2019,2021, we had no outstandingnot employed any interest rate derivative hedges againstproducts to hedge our variable rate debt obligations. However, we may enter into interest rate hedging agreements in the future to mitigate our exposure to interest rate risk.
We periodically enter into interest rate locks to hedge the interest rate exposure created by anticipated fixed rate debt issuances, which are designated as cash flow hedges. When interest rate locks are settled, any accumulated gain or loss included as a component of other comprehensive income (loss) will be amortized to interest expense over the term of the forecasted hedged transaction which is equivalent to the term of the interest rate locks.
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 mortgage 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 as of (in thousands):

Foreign Currency Risk
A significant portion of our revenue is denominated in U.S. dollars, however, approximately 58% of our revenues and 55% 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 Euro, British pound, Japanese yen, Singapore dollar, Hong Kong dollar, Australian dollar and Brazilian real. To help manage the exposure to foreign currency exchange rate fluctuations, we have implemented a number of hedging programs, in particular:
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 remeasurementre-measurement of monetary assets and liabilities denominated in foreign currencies;currencies, and
(iii) a net investment hedging program to hedge the long term investments in our foreign subsidiaries.
Our hedging programs reduce, but do not entirely eliminate, the impact of currency exchange rate movements and their impact on ourthe consolidated balance sheets, statements of operations and statements of cash flows.operations.
We have entered into various foreign currency debt obligations. As of December 31, 2019,2021, the total principal amount of foreign currency debt obligations was $4.4$1.8 billion, including $3.1$1.3 billion denominated in Euro $604.3and $549.7 million denominated in British Pound, $410.1 million denominated in Japanese Yen and $272.7 million denominated in Swedish Krona.Pound. As of December 31, 2019,2021, we have designated $4.1$1.5 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 are recorded as a component of other comprehensive income (loss) in the consolidated balance sheets. Fluctuations in the exchange rates between these foreign currencies 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, 2019,2021, 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 $485.9$200.2 million and $397.5$163.8 million, respectively.
In 2019, weWe are also entered intoparty to cross-currency interest rate swaps where we receive a fixed amountswaps. As of U.S. DollarsDecember 31, 2021 and pay a fixed amount of Euros, with a2020, the total notional amountamounts of $750.0 million.cross-currency interest rate swap contracts outstanding were $4.0 billion and $3.3 billion, respectively. The cross-currency interest rate swaps are designated as hedges of our net investment in European operationsforeign subsidiaries and changes in the fair value of these swaps are recorded as a component of accumulated other comprehensive income (loss) in the condensed consolidated balance sheet.sheets. If the U.S. Dollar weakened or strengthened by 10% in comparison to Euro,foreign currencies, we estimate our obligation to cash settle these hedges would have recorded an additional loss of $93.1increased or decreased by approximately $456.3 million or gain of $76.2and $374.0 million, respectively, within accumulated other comprehensive income (loss) as of December 31, 2019.respectively.
The U.S. Dollar strengthened relative to certain of the currencies of the foreign countries in which we operate during the year ended December 31, 2019.2021. This has impacted our condensed consolidated financial position and results of operations during this period, including the amount of revenues that we reported. Continued strengthening or weakening of the U.S. Dollar will continue to impact us in future periods.
With the existing cash flow hedges in place, a hypothetical additional 10% strengthening of the U.S. dollarDollar during the year ended December 31, 20192021 would have resulted in a reduction of our revenues and a reduction of our operating expenses including depreciation and amortization expenses,expense by approximately $153.7$205.1 million and $152.5$202.2 million, respectively.
With the existing cash flow hedges in place, a hypothetical additional 10% weakening of the U.S. dollarDollar during the year ended December 31, 20192021 would have resulted in an increase of our revenues and an increase of our operating expenses including depreciation and amortization expenses, by approximately $188.2$255.4 million and $188.4$253.7 million, 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 in certain locations in the U.S., Switzerland, Italy, Sweden, Ireland, Bulgaria, Poland, Spain, Portugal, Australia, Brazil, Bulgaria, Canada, China, Finland, France, Germany, Ireland, Italy, Japan, the Netherlands, Poland, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United Kingdom.U.S..
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.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). 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, 2019.2021.
Management'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, 2019.2021.
The effectiveness of our internal control over financial reporting as of December 31, 20192021 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.

Table of Contents
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 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 20192021 that has materially affected, or is reasonable likely to affect, our internal controls over financial reporting. While we implemented certain internal controls related to the adoption of ASC 842, Leases, to ensure we adequately assessed the impact of the new lease accounting standard on our financial statements to facilitate the adoption effective January 1, 2019, we do not believe these have had a material effect on our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Equinix, Inc.
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Equinix, Inc. and its subsidiaries (the “Company”) as of December 31, 20192021 and 2018,2020, and the related consolidated statements of operations, of comprehensive income (loss), of stockholders' equity and other comprehensive income (loss) and of cash flows for each of the three years in the period ended December 31, 2019,2021, including the related notes and financial statement schedule listed in the 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, 2019,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 20192021 and 2018,2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 20192021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
ChangesChange in Accounting PrinciplesPrinciple
As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for leases as of January 1, 2019 and the manner in which it accounts for revenue from contracts with customers as of January 1, 2018.2019.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, 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 the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our 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 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 regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial 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.

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (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'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.

Critical Audit Matters

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

As described in Notes 1 and 14 to the consolidated financial statements, the Company recorded income tax expense of $185.4$109.2 million for the year ended December 31, 2019.2021. The Company has been operating as a real estate investment trust for federal income tax purposes (“REIT”("REIT") effective January 1, 2015. As a result, the Company may deduct the distributionsdividends made to its stockholders from taxable income generated by the Company and that of its qualified REIT subsidiaries ("QRSs"). The Company’s qualification and taxation as a REIT dependsdepend 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, management estimates the fair market value of assets within its QRSs and taxable REIT subsidiaries (“TRSs”) using a discounted cash flow approach, by calculating the present value of forecasted future cash flows. Management applies discount rates based on industry benchmarks relative to the market and forecasting risks. Other significant assumptions used by management to estimate the fair market value of assets in QRSs and TRSs include projected revenue growth, projected operating margins, and projected capital expenditures. Management revisits significant assumptions periodically to reflect any changes due to business or economic environment.

The principal considerations for our determination that performing procedures relating to theincome taxes - REIT asset tests is a critical audit matter are (i) there wasthe significant judgment by management inwhen determining the fair market value of REIT and non-REIT assets, which in turn led to a high degree of subjectivity in performing procedures relating to the REIT asset test,tests, (ii) there wasthe significant audit effort and judgment in evaluating audit evidence related to the significant assumptions used in the REIT asset test, includingrelated to the discount rates, projected revenue growth, projected operating margins, and projected capital expenditures, and (iii) the audit effort involved the use of professionals with specialized skill and knowledge to assist in performing these procedures.knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the REIT asset test,tests, including controls over themanagement's determination of the fair market value of REIT and non-REIT assets. These procedures also included, among others, testing management’s process for estimating the fair market value of the REIT and non-REIT assets; evaluating the appropriateness of the

the completeness and accuracy of underlying data used in the approach; and evaluating the significant assumptions used by management includingrelated to the discount rates, projected revenue growth, projected operating margins, and projected capital expenditures. Evaluating management’s assumptions related to projected revenue growth, projected operating margins, and projected capital expenditures involved considering the current and past performance of the Company, economic and industry trends, as well as whether these assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge were used to assist in the evaluation of the Company’s discounted cash flow approach and certain significantthe assumptions including therelated to discount rates.

Cash, Cash Equivalents and Short-Term Investments
The Company considersWe consider all highly liquid instruments with an original maturity from the date of purchase of 90 days or less to be cash equivalents. Cash equivalents consist of money market mutual funds and certificates of deposit with original maturities up to 90 days. Short-term investments generally consist of certificates of deposit with original maturities of between 90 days and 1 year. Publicly traded equity securities are measured at fair value with changes in the fair values recognized within other income (expense) in the Company'sour consolidated statements of operations. The Company reviews itsWe review our investment portfolio quarterly to determine if any securities may be other-than-temporarily impaired due to increased credit risk, changes in industry or sector of a certain instrument or ratings downgrades.
Equity Method Investments
The Company entersWe enter into joint venture or partnership arrangements to invest in certain entities for business development objectives. At the inception of these arrangements the Company assesses itsand if a reconsideration event has occurred, we assess our interests with othersuch entities to determine whether any of suchthe entities meet the definition of a variable interest entity ("VIE").VIE. A VIE is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support, or (ii) has equity investors who lack the characteristics of a controlling financial interest. The Company isWe are required to consolidate the assets and liabilities of VIEs when it iswe are deemed to be the primary beneficiary. The primary beneficiary of a VIE is the entity that meets both of the following criteria: (i) has the power to make decisions that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. As of December 31, 2019,For VIEs where we are not the Company concluded that it did not have any significant investments in entitiesprimary beneficiary, and other joint ventures or partnerships that are deemed to be VIEs.

Equity investments are subsequently adjusted for cash contributions, distributions and the Company'sour share of the income and losses of the investees.

Financial Instruments and Concentration of Credit Risk
Financial instruments which potentially subject the Companyus to concentrations of credit risk consist of cash and cash equivalents, short-term investments and accounts receivable. Risks associated with cash and cash equivalents and short-term investments are mitigated by the Company'sour investment policy, which limits the Company'sour investing to only those marketable securities rated at least A-1/P-1 Short Term Rating or A-/A3 Long Term Rating, as determined by independent credit rating agencies.

Property, Plant and Equipment
Property, plant and equipment are stated at the Company'sour original cost or at fair value for property, plant and equipment acquired through acquisitions, net of depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. Buildings under finance leases, Leasehold improvements and integral equipment at leased locations are amortized over the shorter of the lease term or the estimated useful life of the asset or improvement. Leasehold improvements acquired through acquisition
We capitalize certain internal and external costs associated with the development and purchase of internal-use software in property, plant and equipment, net on the consolidated balance sheets. This includes costs incurred in cloud computing arrangements ("CCA"), where it is both feasible and contractually permissible without significant penalty for us to take possession of the software. All other CCAs are considered service contracts, and the licensing and implementation costs incurred associated with such contracts are capitalized in other assets on the consolidated balance sheets. Capitalized internal-use software costs and capitalized implementation costs are amortized on a straight-line basis over the shorter of the useful life of the assets or terms that include required lease periods and renewals that are deemed to be reasonably assured at the date of acquisition. Leasehold improvements that are placed into service significantly after and not contemplated at or near the beginning of the lease term are amortized over the shorter of the useful life of the assets or a term that includes required lease periods and renewals that are deemed to be reasonably assured at the date the leasehold improvements are purchased.
The Company's estimated useful lives of itsthe software or arrangements.
Our estimated useful lives of property, plant and equipment are generally as follows:
Core systems3-403-40 years
Buildings12-5812-60 years
Leasehold improvements12-4012-40 years
Personal Property, including capitalized internal-use software3-103-10 years

The Company'sOur 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 hasWe contracted out substantially all of the construction and expansion efforts of itsour 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 haswe 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 itsWe review our property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or an asset group 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 or an asset group 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 an asset group or a continuous deterioration of the Company'sour financial condition. Recoverability of assets or asset groups to be held and used is assessed by comparing the carrying amount of an asset or an asset group to estimated undiscounted future net cash flows expected to be generated by the asset.asset or the asset group. If the carrying amount of the asset or the asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized byin the amount by which the carrying amount of the asset or the asset group exceeds the fair value of the asset. The CompanyWe did not record any impairment charges related to itsour property, plant and equipment during the years ended December 31, 2019, 20182021, 2020 and 2017.2019.

The Company entersWe enter into non-cancellable lease arrangements as the lessee primarily for itsour data center spaces, office spaces and equipment. Assets acquired through finance leases are included in property, plant and equipment, net on the consolidated balance sheets. In addition, a portion of the Company'sour property, plant and equipment are used for revenue arrangements which are accounted for as operating leases where the Company iswe are the lessor.
Assets Held for Sale
Assets and liabilities to be disposed of that meet all of the criteria to be classified as held for sale are reported at the lower of their carrying amounts or fair values less costs to sell. The CompanyWe recorded an impairment charge of $15.8$7.3 million relating to assets held for sale for the year ended December 31, 2019.2020. Assets are not depreciated or amortized while they are classified as held for sale. For further information on the Company'sour assets held for sale, see Note 5.
Asset Retirement Costs and Asset Retirement Obligations
Our asset retirement obligations are primarily related to our IBX data centers, of which the majority are leased under long-term arrangements and are required to be returned to the landlords in their original condition. The majority of our IBX data center leases have been subject to significant development by us in order to convert them from, in most cases, vacant buildings or warehouses into IBX data centers. 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 accreteswe accrete the liability in relation to the asset retirement obligations over time and the accretion expense is recorded as a cost of revenue. The Company's asset retirement obligations are primarily related to its IBX data centers, of which the majority are leased under long-term arrangements and are required to be returned to the landlords in their original condition. The majority of the Company'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. For further information on the Company'sour leases, see Note 10.7.
Goodwill and Other Intangible Assets
The Company hasWe have 3 reportable segments comprised of the 1) Americas, 2) EMEA and 3) Asia-Pacific geographic regions, which the Companywe also determined are itsour reporting units. Goodwill is not amortized and is tested for impairment at least annually or more often if and when circumstances indicate that goodwill is not recoverable.
The Company assessesWe 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. Qualitative factors considered in the assessment include industry and market conditions, overall financial performance, and other relevant events and factors affecting the reporting unit. If, after assessing the qualitative factors, the Company determineswe determine that it is not more likely than not that the fair value of a reporting unit is less than its carrying value, then performing a quantitative impairment test is unnecessary. However, if the Company concludeswe conclude otherwise, then it iswe are required to perform a quantitative goodwill impairment test. The quantitative 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 not considered impaired. If the carrying value of the reporting unit exceeds its fair value, any excess of the reporting unit goodwill carrying value over the respective implied fair value is recognized as an impairment loss.
As of December 31, 2021, 2020 and 2019, 2018 and 2017, the Companywe concluded that it was more likely than not that goodwill attributed to the Company'sour Americas, EMEA and Asia-Pacific reporting units was not impaired as the fair value of each reporting unit exceeded the carrying value of its respective reporting unit, including goodwill.
Substantially all of the Company'sour intangible assets are subject to amortization and are amortized using the straight-line method over their estimated period of benefit. The Company performsWe perform a review of 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 undiscounted 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 CompanyWe did not record any impairment charges related to itsour other intangible assets during the years ended December 31, 2019, 20182021, 2020 and 2017.

Debt Issuance Costs
Costs and fees incurred upon debt issuances are capitalized and are amortized over the life of the related debt based on the effective interest method. Such amortization is included as a component of interest expense. Debt issuance costs related to outstanding debt are presented as a reduction of the carrying amount of the debt obligation and debt issuance costs related to the revolving credit facility are presented as other assets. For further information on debt facilities, see Note 11 below.
Derivatives and Hedging Activities
The Company usesWe use derivative instruments, including foreign currency forwards and options and cross-currency interest rate swaps, to manage certain foreign currency exposures. Derivative instruments are viewed as risk management tools by the Companyus and are not used for speculative purposes. The Company recognizesWe recognize all derivatives on the Company'sour consolidated balance sheets at fair value. The accounting for changes in the value of a derivative depends on whether the contract qualifies and has been designated 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 and 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 the effectiveness assessment methodology. For cash flow hedges, the Company useswe use regression analysis at the time they are designated to assess their effectiveness. Hedge designations are reviewed on a quarterly basis to assess whether circumstances have changed that would disrupt the hedge instrument's relationship to the forecasted transactions or net investment.
The Company usesWe use the forward method to assess effectiveness of qualifying foreign currency forwards that are designated as cash flow hedges, whereby, the change in the fair value of the derivative is recorded in other comprehensive income (loss) and reclassified to the same line item in the consolidated statement of operations that is used to present the earnings effect of the hedged item when the hedged item affects earnings. The Company usesWe use the spot method to assess effectiveness of qualifying foreign currency exchange options that are designated as cash flow hedges, whereby, the change in fair value due to foreign currency exchange spot rates is recorded in other comprehensive income (loss) and reclassified to the same line item in the consolidated statement of operations that is used to present the earnings effect of the hedged item when the hedged item affects earnings, and the change in fair value of the excluded component is recorded in other comprehensive income (loss) and amortized on a straight-line basis to the same line item in the consolidated statement of operations that is used to present the earnings effect of the hedged item. When two or more derivative instruments in combination are jointly designated as a cash flow hedging instrument, as with foreign currency exchange option collars, they are treated as a single instrument. If the hedge relationship is terminated for any derivatives designated as cash flow hedges, then the change in fair value of the derivative recorded in other comprehensive income (loss) is recognized in earnings when the previously hedged item affects earnings, consistent with the original hedge strategy. For hedge relationships that are discontinued because the forecasted transaction is not expected to occur according to the original strategy, then any related derivative amounts recorded in other comprehensive income (loss) are immediately recognized in earnings.
From time to time, the Company enters intowe use derivative instruments, including treasury lock agreements to add stability to interest expenselocks and swap locks (collectively, "interest rate locks") to manage its exposure tocertain interest rate movements.

Fair Value of Financial Instruments
The carrying value of the Company'sour cash and cash equivalents, short-term investments and derivative instruments represent their fair value, while the Company'sour 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'sour debt, which is traded in the public debt market, is based on quoted market prices. The fair value of the Company'sour debt, which is not publicly traded, is estimated by considering the Company'sour credit rating, current rates available to the Companyus for debt of the same remaining maturities and terms of the debt.
Fair Value Measurements
The Company measuresWe measure and reportsreport certain financial assets and liabilities at fair value on a recurring basis, including itsour investments in money market funds, certificates of deposit, publicly traded equity securities and derivatives.
The CompanyWe also followsfollow 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.value; and
Assets and liabilities classified as held for sale are measured at fair value less costs to sell and reported at the lower of the carrying amounts or the fair values less costs to sell.

ROU lease liabilities are measured based on the present value of fixed lease payments over the lease term. ROU assets consist of (i) initial measurement of the lease liability; (ii) lease payments made to the lessor at or before the commencement date less any lease incentives received; and (iii) initial direct costs incurred by the Company.us. Lease payments may vary because of changes in facts or circumstances occurring after the commencement, including changes in inflation indices. Variable lease payments that depend on an index or a rate (such as the Consumer Price Index or a market interest rate) are included in the measurement of ROU assets and lease liabilities using the index or rate at the commencement date. Subsequent changes to lease payments based on changes to the index and rate are accounted for as variable lease payments and recognized in the period they are incurred. Variable lease payments that do not depend on an index or a rate are excluded from the measurement of ROU assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred. Since most of the Company'sour leases do not provide an implicit rate, the Company uses itswe use our own incremental borrowing rate ("IBR") on a collateralized basis in determining the present value of lease payments. The Company utilizesWe utilize a market-based approach to estimate the IBR. The approach requires significant judgment. Therefore, the Company utilizeswe utilize different data sets to estimate IBRs via an analysis of (i) yields on comparable credit rating composite curves; (ii) sovereign rates; (iii)(ii) yields on our outstanding public debt; and (iv) historical difference in yields(iii) indicative pricing on the curves of ourboth secured and unsecured rated debt.

The majority of the Company'sour lease arrangements include options to extend the lease. If the Company iswe are reasonably certain to exercise such options, the periods covered by the options are included in the lease term. The depreciable lives of certain fixed assets and leasehold improvements are limited by the expected lease term. The Company hasWe have certain leases with an initial term of 12 months or less. For such leases, the Companywe elected not to recognize any ROU asset or lease liability on the consolidated balance sheet. The Company hasWe have lease agreements with lease and non-lease components. The CompanyWe elected to account for the lease and non-lease components as a single lease component for all classes of underlying assets for which the Company haswe have identified as lease arrangements. For further information on leases, see Note 10 below.
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 solutions and (4) other revenues consisting of rental income from tenants or subtenants. The remainder of the Company'sour 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. For further information (seeon segment information, see Note 17).17 below.
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 1 to 3 years for IBX data center colocation customers. Non-recurring installation fees, although generally paid upfront upon installation, are deferred and recognized ratably over the contract term. Professional service fees and equipment sales are recognized in the period when the services were provided. For the contracts with customers that contain multiple performance obligations, the Company accountswe account for individual performance obligations separately if they are distinct or as a series of distinct obligations if the individual performance obligations meet the series 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 performance 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. Other judgments include determining if any variable consideration should be included in the total contract value of the arrangement such as price increases.
Revenue is generally recognized on a gross basis as a principal versus on a net basis as an agent, as the Company iswe are primarily responsible for fulfilling the contract, bearsbear inventory risk and hashave discretion in establishing the price when selling to the customer. To the extent the Company doeswe do not meet the criteria for recognizing revenue on a gross basis, the Company recordswe record the revenue on a net basis. Revenue from contract settlements, when a customer wishes to terminate their

terminate their contract early, is treated as a contract modification and recognized ratably over the remaining term of the contract, if any.
The Company guaranteesWe guarantee certain service levels, such as uptime, as outlined in individual customer contracts. If these service levels are not achieved due to any failure of the physical infrastructure or offerings, or in the event of certain instances of damage to customer infrastructure within the Company'sour IBX data centers, the Companywe would reduce revenue for any credits or cash payments given to the customer. Historically, these credits and cash payments have not been significant.
The Company entersWe enter into revenue contracts with customers for data centers and office spaces, which contain both lease and non-lease components. The CompanyWe elected to adopt the practical expedient which allows lessors to combine lease and non-lease components, by underlying class of asset, and account for them as one component if they have the same timing and pattern of transfer. The combined component is accounted for in accordance with the current lease accounting guidance ("Topic 842") if the lease component is predominant, and in accordance with the current revenue accounting guidance ("Topic 606")606 if the non-lease component is predominant. Lessors are permitted to adopt this practical expedient on a retrospective or prospective basis. The CompanyWe elected to apply the practical expedient prospectively based on classes of underlying assets. In general, customer contracts for data centers are accounted for under Topic 606 and Customercustomer contracts for the use of office space are accounted for under Topic 842, which are generally classified as operating leases and are recognized on a straight-line basis over the lease term.
Certain customer agreements are denominated in currencies other than the functional currencies of the parties involved. Under applicable accounting rules, the Company iswe are deemed to have foreign currency forward contracts embedded in these contracts. The CompanyWe assessed these embedded contracts and concluded them to be foreign currency embedded derivatives (see Note 8). These instruments are separated from their host contracts and held on the Company'sour consolidated balance sheet at their fair value. The majority of these foreign currency embedded derivatives arise in certain of the Company'sour subsidiaries where the local currency is the subsidiary's functional currency and the customer contract is denominated in the U.S. dollar. Changes in their fair values are recognized within revenues in the Company'sour consolidated statements of operations.
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 accountcredit losses and is recognized in the period when the Company haswe have transferred products or provided services to itsour 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 haswe have determined that the Company'sour contracts generally do not include a significant financing component. The Company assessesWe assess collectability based on a number of factors, including past transaction history with the customer and the credit-worthiness of the customer. The CompanyWe generally doesdo not request collateral from itsour customers although in certain cases the Company obtainswe obtain a security interest in a customer's equipment placed in itsour IBX data centers or obtainsobtain a deposit. The CompanyWe also maintainsmaintain an allowance for doubtful accounts for estimated losses on a lifetime loss basis resulting from the inability of itsour customers to make required payments for which the Companywe had expected to collect the revenues. Ifrevenues in accordance with the new credit loss guidance accounting guidance ("Topic 326"). The financial condition of the Company'sour customers were to deteriorate or if they became insolvent, resulting in an impairment of their ability to make payments, greater allowances for doubtful accountscredit losses may be required. Management specifically analyzes accounts receivable and current economic news, conditions and trends, historical bad debts,loss rates, customer concentrations, customer credit-worthiness, and changes in customer payment terms and any applicable long term forecast when evaluating revenue recognition and the adequacy of the Company'sour reserves. Any amounts that were previously recognized as revenue and subsequently determined to be uncollectable are charged to bad debt expense included in sales and marketing 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 off after management has determined that the likelihood of collection is not probable.
A contract asset exists when the Company haswe have transferred products or provided services to itsour customers but customer payment is contingentconditioned on reasons other than the passage of time, such as upon the satisfaction of additional performance obligations. Certain contracts include terms related to price arrangements such as price increases and free months. The Company recognizesWe recognize revenues

Deferred revenue (a contract liability) is recognized when the Company haswe have 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. ContractIn 2021, contract costs are amortized over the estimated period of benefit5.5 years on a straight-line basis. The CompanyWe elected to apply the practical expedient which allows the Companyus 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 forbased on the future tax consequences attributable to differences that exists between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, andas well as tax attributes such as operating loss, capital loss and tax credits carryforwards.carryforwards on a taxing jurisdiction basis. 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's widely understood administrative practices and precedents. Recognized income tax positions are measured at the largest amount that has a greater than 50 percent likelihood of being realized. Any subsequent changes in recognition or measurement are reflected in the period in which the change in judgment occurs.
The CompanyWe elected to be taxed as a REIT for U.S. federal income tax purposes beginning with itsour 2015 taxable year. As a result, the Companywe may deduct the distributionsdividends made to itsour stockholders from taxable income generated by the Companyus and itsthat of our qualified REIT subsidiaries ("QRSs"). The Company'sOur dividends paid deduction generally eliminates the U.S. federal taxable income of the Companyour REIT and its QRSs, resulting in no U.S. federal income tax due. However, the Company'sour domestic taxable REIT subsidiaries ("TRSs") will continue to beare subject to the U.S. corporate income taxes on any taxable income generated by them. In addition, theour foreign operations of the Company will continue to beare subject to local income taxes regardless of whether the foreign operations are operated as QRSs or TRSs.
The Company'sOur qualification and taxation as a REIT dependsdepend on itsour satisfaction of certain asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. The Company'sOur ability to satisfy quarterly asset tests depends upon itsour analysis and the fair market values of itsour REIT and non-REIT assets. For purposes of the quarterly REIT asset tests, the Company estimateswe estimate the fair market value of assets within itsour QRSs and TRSs using a discounted cash flow approach, by calculating the present value of forecasted future cash flows. The Company appliesWe apply discount rates based on industry benchmarks relative to the market and forecasting risks. Other significant assumptions used to estimate the fair market value of assets in QRSs and TRSs include projected revenue growth, projected operating margins, and projected capital expenditures. The Company revisitsWe revisit significant assumptions periodically to reflect any changes due to business or economic environment.
For further information on income taxes, see Note 14 below.
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. The CompanyWe generally recognizesrecognize stock-based compensation expense on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. However,

The Company grantsWe grant restricted stock units ("RSUs") or restricted stock awards ("RSAs") to itsour employees and these equity awards generally have only a service condition. The Company grants restricted stock unitsWe grant RSUs to itsour executives and these awards generally have a service and performance condition or a service and market condition. To date, any performancePerformance conditions contained in an equity award are generally tied to theour financial performance of the Company or a specific region of the Company. The Company assessesour company. We assess the probability of meeting these performance conditions on a quarterly basis. The majority of the Company's equity awardsour RSUs vest over 4four years, although certain of the equity awards for executives vest over a range of 2two to 4four years. Our RSAs vest over three years. The valuation of restricted stock unitsRSUs and RSAs 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'sour stock price on the date of grant. The Company usesWe use a Monte Carlo simulation option-pricing model to determine the fair value of restricted stock unitsRSUs with a service and market condition.
The Company usesWe use the Black-Scholes option-pricing model to determine the fair value of itsour employee stock purchase plan.plan ("ESPP"). The determination of the fair value of shares purchased under the employee stock purchase planESPP is affected by assumptions regarding a number of complex and subjective variables including the Company'sour expected stock price volatility over the term of the awards and actual and projected employee stock purchase behaviors. The CompanyWe 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 was based on average dividend yields and 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). The Company recordsWe record the excess tax benefits from stock-based compensation as income tax expense through the statement of operations.
For further information on stock-based compensation, see Note 13 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 exchange 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 in the period incurred and recorded within other income (expense). Certain inter-company balances are designated as 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.
Earnings Per Share
The Company computesWe compute basic and diluted EPS for net income. Basic EPS is computed using net income and the weighted-average number of common shares outstanding. Diluted EPS is computed using net income and the weighted-average number of common shares outstanding plus any dilutive potential common shares outstanding. Dilutive potential common shares include the assumed exercise, vesting and issuance activity of employee equity awards using the treasury stock method. SeeFor further information on earnings per share, see Note 4 below.
Treasury Stock
The Company accountsWe account for treasury stock under the cost method. When treasury stock is re-issued at a higher price than its cost, the difference is recorded as a component of additional paid-in capital to the extent that there are gains to

Coronavirus (COVID-19) Update
F-19During the year ended December 31, 2021, the COVID-19 pandemic did not have a material impact on our financial statements. During the year ended December 31, 2020, we recorded an insignificant amount of revenue reserve and allowance for credit losses related to our response to the COVID-19 pandemic, and incurred one-time cash bonuses and compensation expense of $8.6 million for our IBX data center employees, as well as other employees to support their work-from-home requirements. This was partially offset by lower travel expenses due to travel restrictions as a result of the COVID-19 pandemic. During the year ended December 31, 2021 and 2020, we also evaluated our goodwill, long-lived assets, including property, plant and equipment, lease right-of-use assets and intangible assets, noting no indicators of impairment resulting from the pandemic.


TableThe full impact that the ongoing COVID-19 pandemic will have on our future consolidated financial statements remains uncertain and ultimately will depend on many factors, including the duration and potential cyclicity of Contentsthe health crisis, further public policy actions to be taken in response, as well as the continued impact of the pandemic on the global economy and our customers and vendors. We will continue to evaluate the nature and extent of these potential impacts to our business and consolidated financial statements.

The ASU requires enhanced qualitative and quantitative 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. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with Customers ("early adoption permitted. We adopted this new ASU 2014-09") and issued subsequent amendments to the initial guidance, collectively referred as "Topic 606." Onon January 1, 2018, the Company adopted Topic 6062020 using the modified retrospective approach applied to those contracts, which were not completed as of January 1, 2018, and recognizedrecorded a net increasedecrease to the opening retained earnings of $269.8$0.9 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.
Derivatives and Hedging
In August 2017, FASB issued ASU 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.
The Company adopted ASU 2017-12 on January 1, 2019 using the modified retrospective approach. For cash flow hedges existing on the date of adoption, the Company recognized the cumulative effect of the change on the opening balance of accumulated other comprehensive income (loss) with a corresponding adjustmentincrease to the opening balance of retained earningsallowance for amounts previously recognized in earnings related to ineffectiveness. The adoption of this standard did not have a material impact on the Company's condensed consolidated financial statements.credit

Leases
In February 2016, FASB issued ASU 2016-02, Leases and issued subsequent amendments to the initial guidance, collectively referred to as "Topic 842." Topic 842 replaces the guidance in former ASC Topic 840, Leases.losses. The new lease guidance increases transparency and comparability among organizations by requiring the recognition of the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee'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's right to use, or control the use of, a specified asset for the lease term. Topic 842 allows entities to adopt with one of two methods: the modified retrospective transition method or the alternative transition method.
On January 1, 2019, the Company adopted Topic 842 using the alternative transition method. Therefore, results for reporting periods beginning after January 1, 2019 are presented under Topic 842, while comparative information hasadoption did not been restated and continues to be reported under accounting standards in effect for those periods. The Company recognized the cumulative effects of initially applying the standard as an adjustment to the opening balance of retained earnings in the period of adoption.
In adopting the new guidance, the Company elected to apply the package of practical expedients permitted under the transition guidance which allows the Company not to reassess (1) whether any expired or existing contracts contain leases under the new definition of a lease; (2) lease classification for any expired or existing leases; and (3) whether previously capitalized initial direct costs would qualify for capitalization under Topic 842. The Company also elected to apply 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.
Adoption of the standard hadhave a significant impact on other financial assets within the Company's financial results, includingscope of Topic 326, such as contract assets.
Income Taxes

The ASU simplifies accounting for income taxes by removing certain exceptions to the retained earnings.general principles in Topic 740. The cumulative effectASU also improves consistent application of the changes made to its consolidatedand simplifies generally accepted accounting principles ("GAAP") for other areas of Topic 740 by clarifying and amending existing guidance. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted including adoption in any interim period for periods for which financial statements have not yet been issued.

Reference Rate Reform
In March 2020, FASB issued ASU 2020-04, Reference Rate Reform ("Topic 848"): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In addition, FASB issued ASU 2021-01, Reference Rate Reform ("Topic 848"), which clarifies the scope of Topic 848. Collectively, the guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. ASU 2021-01 is effective upon issuance and ASU 2020-04 was effective for all entities as of March 12, 2020, and together remain effective through December 31, 2022. We adopted these ASUs upon their respective issuances and there was no impact on our consolidated financial statements as a result of adopting the guidance. We will evaluate our debt, derivative and lease contracts that may become eligible for modification relief and may apply the elections prospectively as needed.

Property, plant and equipment - The fair value of customer relationships was estimated by applying an income approach, by calculating the present value of estimated future operating cash flows generated from existing customers less costs to realize the revenue. The Company applied discount rates of 7.3% for Metronode and 8.2% for Infomart Dallas, which reflected the nature of the assets as they relate to the risk and uncertainty of the estimated future operating cash flows. Other assumptions used to estimate the fair value of customer relationships included projected revenue growth, capital expenditures, probability of renewal, customer attrition rates and operating margins. The fair value of Infomart Dallas' trade name was estimated using the relief from royalty method under the income approach. The Company applied a relief from royalty rate of 1.5% and a discount rate of 8.2%. The fair value of in-place leases was estimated by projecting the avoided costs, such as the cost of originating the acquired in-place leases, during a typical lease up period. 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 fair valuevalues of property, plant and equipment wasacquired from these 4 acquisitions were 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.approach. 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 Verizon Data Center Acquisition constitutes a business under the accounting standard for business combinations and, therefore, was accounted for as a business combination using the acquisition method of accounting. During the three months ended March 31, 2018, the Company had completed the detailed valuation analysis to derive the fair value of assets acquired and liabilities assumed and updated the final allocation of purchase price from provisional amounts reported as of June 30, 2017, which primarily resulted in a decrease in intangible assets of $9.0 million and an increase in goodwill of $7.7 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 and including December 31, 2018.

Included in this amount is a customer relationship intangible asset for Verizon totaling $245.3 million. Pursuant to the acquisition agreement, the Company formalized agreements to provide pre-existing space and services to Verizon at the acquired data centers.
The fair value of customer relationships was estimated by applying an income approach. The Company applied discount rates ranging from 7.7% to 12.2%, which reflected the nature of the assets as they relate to the risk and uncertainty of the estimated future operating cash flows. Other assumptions used to estimate the fair value of customer relationships include projected revenue growth, customer attrition rates, sales and marketing expenses and operating margins. 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 fair 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. The cost approach is to use the replacement or reproduction cost as an indicator of fair value. The 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.

Non - Variable Interest Entity (VIE) Joint Venture

EMEA 1 Joint Venture
In 2019, we entered into a joint venture in the form of a limited liability partnership with GIC (the "EMEA 1 Joint Venture"), to develop and operate xScale data centers in Europe. The EMEA 1 Joint Venture is not a variable interest entity ("VIE") given that both equity investors' interests have the characteristics of a controlling financial interest and it is sufficiently capitalized to sustain its operations, requiring additional funding from its partners only when expanding operations. Our share of income and losses of equity method investments from this joint venture was insignificant for the years ended December 31, 2021 and 2020 and was included in other income (expense) on the consolidated statement of operations.
We committed to make future equity contributions to the EMEA 1 Joint Venture for funding its future development. As of December 31, 2021, we had future equity contribution commitments of $26.0 million.

Asia-Pacific 1 and EMEA 2 Joint Ventures
In 2020, we entered into a second joint venture in the form of a limited liability partnership with GIC (the "Asia-Pacific 1 Joint Venture") to develop and operate xScale data centers in Asia-Pacific.
In 2021, we entered into another joint venture in the form of a limited liability partnership with GIC (the "EMEA 2 Joint Venture") to develop and operate additional xScale data centers in Europe and the Americas (see Note 5 above).
For both the Asia-Pacific 1 Joint Venture and the EMEA 2 Joint Venture, we provide certain management services to their operations and earn fees for the performance of such services. Both joint ventures do not have sufficient funds from operations to be self-sustaining, thus are considered VIEs. The power to direct the activities of these joint ventures that most significantly impact economic performance is shared equally between GIC and us. These activities include data center construction and operations, sales and marketing, financing, and real estate purchases or sales. Decisions about these activities require the consent of both GIC and us. We concluded that neither party is deemed to have predominant control over the Asia-Pacific 1 Joint Venture and EMEA 2 Joint Venture and neither party is considered to be the primary beneficiary. During the years ended December 31, 2021 and 2020, respectively, our share of income and losses of equity method investments from these joint ventures was insignificant both individually and in aggregate, and was included in other income (expense) on the consolidated statement of operations.

9.     Fair Value Measurements
Valuation Methods
Fair value estimates are made as of a specific point in time based on methods using the market approach valuation method which uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities or other valuation techniques. These techniques involve uncertainties and are affected by the assumptions used and the judgments made regarding risk characteristics of various financial instruments, discount rates, estimates of future cash flows, future expected loss experience and other factors.
Cash Equivalents and Investments. The fair value of the Company'sour investments in money market funds approximates their face value. Such instruments are included in cash equivalents. The Company'sOur money market funds and publicly traded equity securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted prices for identical instruments in active markets. The fair value of the Company'sour other investments, including certificates of deposit, approximates their face value. The fair value of these investments is priced based on the quoted market price for similar instruments or nonbinding market prices that are corroborated by observable market data. Such instruments are classified within Level 2 of the fair value hierarchy. The Company determinesWe determine the fair values of itsour Level 2 investments by using inputs such as actual trade data, benchmark yields, broker/dealer quotes and other similar data, which are obtained from quoted market prices, custody bank, third-party pricing vendors or other sources. The Company usesWe use such pricing data as the primary input to make its assessments and determinations as to the ultimate valuation of itsour investment portfolio and has not made, during the periods presented, any material adjustments to such inputs. The Company isWe are responsible for itsour consolidated financial statements and underlying estimates.
The Company usesWe use the specific identification method in computing realized gains and losses. Realized gains and losses from the sale of investments are included within other income (expense) in the Company'sour consolidated statements of operations.

Legislation commonly referred to asOf the Tax Cuts and Jobs Act ("TCJA"), which was signed into law on December 22, 2017, contained many significant changes to the U.S. federal incomeunrecognized tax laws. Among other things, the TCJA reduced the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018, limited the tax deductibility of interest expense, accelerated expensing of certain business assets and transitioned the U.S. international taxation from a worldwide tax system to a territorial tax system by imposing a one-time mandatory repatriation of undistributed foreign earnings. As a result of the reduced 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 completed the analysis of the TCJA's income tax effects and the adjustment to the provisional amount was insignificant.

The Company'suncertain tax position was covered by an indemnification agreement with the Seller. The income tax audit was settled during 2021, as such, the realization of the unrecognized tax benefits resulted in an impairment of the indemnification asset for the same amount, which has been included in Other Income (Expense) on the Consolidated Statements of Operations for the year ended December 31, 2021.

As a result of the Company'sour conversion to a REIT effective January 1, 2015, it is no longer the Company'sour intent to indefinitely reinvest undistributed foreign 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 material U.S. taxes in the post-REIT conversion periods due to the fact that nonethe majority of itsour foreign subsidiaries isare either QRSs or owned directly by a U.S. taxableour REIT subsidiaryand QRSs, and the foreign withholding tax effect would be immaterial. The Company continuesWe continue to assess the foreign withholding tax impact of itsour current policy and doesdo not believe the distribution of itsour foreign earnings would trigger any significant foreign withholding taxes, as athe majority of the foreign jurisdictions where the Company operateswe operate do not impose withholding taxes on dividend distributions to a corporate U.S. parent.

The Company'sOur accounting for deferred taxes involves weighing positive and negative evidence concerning the realizability of the Company'sour deferred tax assets in each taxtaxing jurisdiction. After considering evidence such evidence as the nature, frequency and severity of current and cumulative financial reporting losses, and the sources of future taxable income, taxable income in carryback years permitted by the tax laws and tax planning strategies, the Companywe concluded that valuation allowances were required in certain foreign jurisdictions. The operations in most of the jurisdictions for which a valuation allowance has been established have a history of significant losses as of December 31, 2019.2021. As such, the Company doeswe do not believe these operations have established a sustained history of profitability and that a valuation allowance is, therefore, necessary. The CompanyWe also provided a valuation allowance against certain gross deferred tax assets in certain taxtaxing jurisdictions as these deferred tax assets are not expected to be realizable in the foreseeable future.

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's revenues and results of operations have been subject to significant fluctuations, particularly on a quarterly basis, and the Company'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's cash flows and the cash and cash equivalents and accounts receivable accounts on the Company'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's offerings, the introduction of new offerings, changes in prices and pricing models, trends in the internet infrastructure industry, general economic conditions, extraordinary events such as acquisitions or litigation and the occurrence of unexpected events.
The unaudited quarterly financial information presented below has been prepared by the Company and reflects all adjustments, consisting only of normal recurring adjustments, which in the opinion of management are necessary to present fairly the financial position and results of operations for the interim periods presented.
