EXPLANATORY NOTE 

This report combines the annual reports on Form 10-K for the year ended December 31, 2014 of Digital Realty Trust, Inc., a Maryland corporation, and Digital Realty Trust, L.P., a 

Maryland limited partnership, of which Digital Realty Trust, Inc. is the sole general partner. Unless otherwise indicated or unless the context requires otherwise, all references in this report 
to “we,” “us,” “our,” “our company” or “the company” refer to Digital Realty Trust, Inc. together with its consolidated subsidiaries, including Digital Realty Trust, L.P. Unless otherwise 
indicated or unless the context requires otherwise, all references to “our operating partnership” or “the operating partnership” refer to Digital Realty Trust, L.P. together with its 
consolidated subsidiaries. 

Digital Realty Trust, Inc. is a real estate investment trust, or REIT, and the sole general partner of Digital Realty Trust, L.P. As of December 31, 2014, Digital Realty Trust, Inc. 
owned an approximate 97.8% common general partnership interest in Digital Realty Trust, L.P. The remaining approximate 2.2% common limited partnership interests are owned by non-
affiliated investors and certain directors and officers of Digital Realty Trust, Inc. As of December 31, 2014, Digital Realty Trust, Inc. owned all of the preferred limited partnership interests 
of Digital Realty Trust, L.P. As the sole general partner of Digital Realty Trust, L.P., Digital Realty Trust, Inc. has the full, exclusive and complete responsibility for the operating 
partnership’s day-to-day management and control. 

We believe combining the annual reports on Form 10-K of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. into this single report results in the following benefits: 

• 

• 

• 

enhancing investors’ understanding of our company and our operating partnership by enabling investors to view the business as a whole in the same manner as management 
views and operates the business; 

eliminating duplicative disclosure and providing a more streamlined and readable presentation since a substantial portion of the disclosure applies to both our company and 
our operating partnership; and 

creating time and cost efficiencies through the preparation of one combined report instead of two separate reports.

There are a few differences between our company and our operating partnership, which are reflected in the disclosure in this report. We believe it is important to understand the 
differences between our company and our operating partnership in the context of how we operate as an interrelated consolidated company. Digital Realty Trust, Inc. is a REIT, whose only 
material asset is its ownership of partnership interests of Digital Realty Trust, L.P. As a result, Digital Realty Trust, Inc. does not conduct business itself, other than acting as the sole 
general partner of Digital Realty Trust, L.P., issuing public equity from time to time and guaranteeing certain unsecured debt of Digital Realty Trust, L.P. and certain of its subsidiaries. 
Digital Realty Trust, Inc. itself does not issue any indebtedness but guarantees the unsecured debt of Digital Realty Trust, L.P. and certain of its subsidiaries, as disclosed in this report. 
Digital Realty Trust, L.P. holds substantially all the assets of the company and holds the ownership interests in the company’s joint ventures. Digital Realty Trust, L.P. conducts the 
operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from public equity issuances by Digital Realty Trust, Inc., which are 
generally contributed to Digital Realty Trust, L.P. in exchange for partnership units, Digital Realty Trust, L.P. generates the capital required by the company’s business through Digital 
Realty Trust, L.P.’s operations, by Digital Realty Trust, L.P.’s direct or indirect incurrence of indebtedness or through the issuance of partnership units. 

The presentation of noncontrolling interests in operating partnership, stockholders’ equity and partners’ capital are the main areas of difference between the consolidated financial 

statements of Digital Realty Trust, Inc. and those of Digital Realty Trust, L.P. The common limited partnership interests held by the limited partners in Digital Realty Trust, L.P. are 
presented as limited partners’ capital within partners’ capital in Digital Realty Trust, L.P.’s consolidated financial statements and as noncontrolling interests in operating partnership within 
equity in Digital Realty Trust, Inc.’s consolidated financial statements. The common and preferred partnership interests held by Digital Realty Trust, Inc. in Digital Realty Trust, L.P. are 
presented as general partner’s capital within partners’ capital in Digital Realty Trust, L.P.’s consolidated financial statements and as preferred stock, common stock, additional paid-in 
capital and accumulated dividends in excess of earnings within stockholders’ equity in Digital Realty Trust, Inc.’s consolidated financial statements. The differences in the presentations 
between stockholders’ equity and partners’ capital result from the differences in the equity issued at the Digital Realty Trust, Inc. and the Digital Realty Trust, L.P. levels.

To help investors understand the significant differences between the company and the operating partnership, this report presents the following separate sections for each of the 

company and the operating partnership: 

• 

• 

• 

• 

• 

consolidated financial statements;

the following notes to the consolidated financial statements:

• 

• 

• 

• 

Debt of the company and Debt of the operating partnership;

Income per Share and Income per Unit;

partnership; and 

Quarterly Financial Information;

Liquidity and Capital Resources in Management’s Discussion and Analysis of Financial Condition and Results of Operations;

Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities; and

Selected Financial Data.

This report also includes separate Item 9A. Controls and Procedures sections and separate Exhibit 31 and 32 certifications for each of the company and the operating partnership in 

order to establish that the Chief Executive Officer and Chief Financial Officer of each entity has made the requisite certification and that the company and the operating partnership are 
compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934 and 18 U.S.C. §1350. 

In order to highlight the differences between the company and the operating partnership, the separate sections in this report for the company and the operating partnership specifically 

refer to the company and the operating partnership. In the sections that combine disclosure of the company and the operating partnership, this report refers to actions or holdings as being 
actions or holdings of the company. Although the operating partnership is generally the entity that enters into contracts and joint ventures and holds assets and debt, reference to the 
company is appropriate because the business is one enterprise and the company operates the business through the operating partnership. 

As general partner with control of the operating partnership, Digital Realty Trust, Inc. consolidates the operating partnership for financial reporting purposes, and it does not have 

significant assets other than its investment in the operating partnership. Therefore, the assets and liabilities of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. are the same on their 
respective consolidated financial statements. The separate discussions of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. in this report should be read in conjunction with each other 
to understand the results of the company on a consolidated basis and how management operates the company.

ITEM 1.    BUSINESS 

General 

PART I 

We own, acquire, develop and manage technology-related real estate. We target high-quality, strategically located properties containing applications and operations critical to the day-

to-day operations of technology industry tenants and corporate enterprise datacenter users, including the information technology, or IT, departments of Fortune 100 and financial services 
companies. Our tenant base is diversified within the technology industry and reflects a broad spectrum of regional, national and international tenants that are leaders in their respective 
areas. Digital Realty Trust, L.P., a Maryland limited partnership, is the entity through which Digital Realty Trust, Inc., a Maryland corporation, conducts its business and owns its assets. 
Digital Realty Trust, Inc. operates as a REIT for federal income tax purposes. 

As of December 31, 2014, our portfolio consisted of 131 properties, including 14 properties held as investments in unconsolidated joint ventures and developable land, of which 105 
are located throughout North America, 21 are located in Europe, three are located in Australia and two are located in Asia. We are diversified in major markets where corporate datacenter 
and technology tenants are concentrated, including the Boston, Chicago, Dallas, Los Angeles, New York Metro, Northern Virginia, Phoenix, San Francisco and Silicon Valley metropolitan 
areas in the United States, Amsterdam, Dublin, London and Paris markets in Europe and Singapore, Sydney, Melbourne and Hong Kong markets in the Asia Pacific region. Our properties 
contain a total of approximately 24.6 million rentable square feet including approximately 1.3 million square feet of space under active development, which includes current base building 
and data center projects in progress, and approximately 1.2 million square feet of space held for future development, which includes space held for future data center development and 
excludes space under active development. The 14 properties held as investments in unconsolidated joint ventures have an aggregate of approximately 1.8 million rentable square feet. The 
14 parcels of developable land we own comprised approximately 178 acres. A significant component of our current and future internal growth is anticipated through the development of our 
existing space held for development and acquisition of new properties. As of December 31, 2014, our portfolio, including the 14 properties held as investments in unconsolidated joint 
ventures and excluding space under active development and space held for future development, was approximately 93.2% leased. The types of properties within our focus include: 

• 

• 

• 

Corporate datacenters, which provide secure, continuously available environments for the storage and processing of critical electronic information. Data centers are used for 
disaster recovery purposes, transaction processing and to house corporate IT operations;  

Internet gateway datacenters, which serve as hubs for Internet and data communications within and between major metropolitan areas; and

Technology manufacturing properties and regional or national offices of technology companies that are located in our target markets.

Unlike traditional office and flex/research and development space, the location of and improvements to our facilities are generally essential to our tenants’ businesses, which we 

believe results in high occupancy levels, long lease terms and low tenant turnover. In addition, many of our properties have tenant improvements that have been installed at our tenants’ 
expense. The tenant improvements in our facilities are generally readily adaptable for use by similar tenants. 

Digital Realty Trust, Inc. was incorporated in the state of Maryland on March 9, 2004. Digital Realty Trust, L.P. was organized in the state of Maryland on July 21, 2004. Our 
principal executive offices are located at Four Embarcadero Center, Suite 3200, San Francisco, California 94111. Our telephone number at that location is (415) 738-6500. Our website is 
located at www.digitalrealty.com. The information found on, or otherwise accessible through, our website is not incorporated into, and does not form a part of, this annual report or any 
other report or document we file with or furnish to the U.S. Securities and Exchange Commission, or the SEC.

Recent Developments 

On February 5, 2015, the operating partnership sold the 100 Quannapowitt property for approximately $31 million.The transaction after costs resulted in net proceeds of 
approximately $29 million and a net gain of approximately $9 million. The property was identified as held for sale as of December 31, 2014. 100 Quannapowitt was not a significant 
component of our U.S. portfolio nor does the sale represent a significant shift in our strategy. 

On February 25, 2015, we declared the following dividends per share. The operating partnership will make an equivalent distribution per unit.

We believe we distinguish ourselves from other owners, acquirors and managers of technology-related real estate through our competitive strengths, which include: 

• 

• 

• 

• 

High-Quality Portfolio that is Difficult to Replicate. Our portfolio contains state-of-the-art data center facilities with extensive tenant improvements. Based on current market 
rents and the estimated replacement costs of our properties and their improvements, we believe that they could not be replicated today on a cost-competitive basis. Our portfolio 
of data center facilities is equipped to meet the power and cooling requirements for the most demanding corporate IT applications. Many of the properties in our portfolio are 
located on major aggregation points formed by the physical presence of multiple major telecommunications service providers, which reduces our tenants’ costs and operational 
risks and increases the attractiveness of our buildings. 

Presence in Key Markets. Our portfolio is located in 33 metropolitan areas, including the Boston, Chicago, Dallas, Los Angeles, New York Metro, Northern Virginia, Phoenix, 
San Francisco and Silicon Valley metropolitan areas in the United States, Amsterdam, Dublin, London and Paris markets in Europe and Singapore, Sydney, Melbourne and 
Hong Kong markets in the Asia Pacific region, and is diversified so that no one market represented more than approximately 11% of the aggregate annualized rent of our 
portfolio as of December 31, 2014. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Revenue Base.” 

Proven Experience Executing New Leases. We have considerable experience in identifying and leasing to new tenants. The combination of our specialized data center leasing 
team and customer referrals continues to provide a robust pipeline of new tenants. During the year ended December 31, 2014, we commenced new leases totaling approximately 
1.3 million square feet, which represent approximately $153.8 million in annualized GAAP rent. During the year ended December 31, 2014, we signed new leases totaling 
approximately 1.4 million square feet, which represent approximately $158.6 million in annualized GAAP rent. These leases were comprised of Powered Base Buildings®, Turn-
Key Flex® space, Custom Solutions product and space for ancillary office and other uses. 

Demonstrated Acquisition Capability. As of December 31, 2014, our portfolio consisted of 131 properties, including 14 properties held as investments in unconsolidated joint 
ventures and developable land, for an aggregate of 24.6 million net rentable square feet, including approximately 1.3 million square feet of space under active development and 
approximately 1.2 million square feet of space held for future development. We have developed detailed, standardized procedures for evaluating acquisitions, including income 
producing assets and vacant properties and land suitable for development, to ensure that they meet our financial, technical and other criteria. These procedures and our in-depth 
knowledge of the technology and data center industries allow us to identify strategically located properties and evaluate investment opportunities efficiently and, as appropriate, 
commit and close quickly. Our broad network of contacts within a highly fragmented universe of sellers and brokers of  

2

Index to Financial Statements 

• 

• 

• 

• 

technology-related real estate enables us to capitalize on acquisition opportunities. As a result, we acquired a substantial portion of our properties before they were broadly 
marketed by real estate brokers. 

Flexible Datacenter Solutions. We provide flexible, customer oriented solutions designed to meet the needs of domestic and international companies across multiple industry 
verticals, including Turn-Key Flex®, Powered Base Building® and Custom Solutions options. Our Turn-Key Flex® data centers are move-in ready, physically secure facilities 
with the power and cooling capabilities to support mission-critical IT enterprise applications. We believe our Turn-Key Flex® facilities are effective solutions for tenants that 
lack the expertise, capital budget or desire to provide their own extensive data center infrastructure, management and security. For tenants that possess the ability to build and 
operate their own facility, our Powered Base Building® solution provides the physical location, required power and network access necessary to support a state-of-the-art data 
center. Our in-house engineering and design and construction professionals can also provide tenants with our Custom Solutions product to meet their unique specifications. Our 
Critical Facilities Management® services and team of technical engineers and data center operations experts provide 24/7 support for these mission-critical facilities. 

Differentiating Development Advantages. Our extensive development activity, operating scale and process-based approach to data center design, construction and operations 
result in significant cost savings and added value for our tenants. We have leveraged our purchasing power by securing global purchasing agreements and developing 
relationships with major equipment manufacturers, reducing costs and shortening delivery timeframes on key components, including major mechanical and electrical equipment. 
Utilizing our innovative modular data center design referred to as POD Architecture®, we deliver what we believe to be a technically superior data center environment at 
significant cost savings. In addition, by utilizing our POD Architecture® to develop new Turn-Key Flex® facilities in our existing Powered Base Building® facilities, on average 
we are able to deliver a fully commissioned facility in just under 30 weeks. Finally, our access to capital allows us to provide data center solutions for tenants that do not want to 
invest their own capital. 

Diverse Tenant Base Across a Variety of Industry Sectors. We use our in-depth knowledge of the requirements and trends for Internet and data communications and 
corporate data center users to market our properties to domestic and international tenants with specific technology needs. At December 31, 2014, we had over 650 tenants across 
a variety of industry verticals, ranging from financial services, cloud and information technology services, to manufacturing, energy, health care and consumer products. Our 
largest tenant, comprised of subsidiaries of CenturyLink, Inc., accounted for approximately 7.2% of the aggregate annualized rent of our portfolio as of December 31, 2014 and 
no other single tenant accounted for more than approximately 6.7% of the aggregate annualized rent of our portfolio. 

Experienced and Committed Management Team and Organization. Our senior management team has many years of experience in the technology or real estate industries, 
including experience as investors in, advisors to and founders of technology companies. We believe that our senior management team’s extensive knowledge of both the real 
estate and the technology industries provides us with a key competitive advantage. A significant portion of compensation for our senior management team and directors is in the 
form of common equity interests in our company, which aligns their interests with those of our stockholders. 

Business and Growth Strategies 

Our primary business objectives are to maximize sustainable long-term growth in earnings and funds from operations per share and unit and to maximize cash flow and returns to our 

stockholders and our operating partnership’s unitholders, including through the payment of distributions. Our business strategies to achieve these objectives are: 

• 

• 

Achieve Superior Returns on Development Inventory. At December 31, 2014, we had approximately 1.3 million square feet of space under active development for Turn-Key 
Flex®, Powered Base Building® and Custom Solutions products, all of which are expected to be income producing on or after completion, in five U.S. markets, two Australian 
markets, one Canadian market and one European market, consisting of approximately 0.7 million square feet of base building construction and 0.6 million square feet of data 
center construction. We may continue to build out our development portfolio when justified by anticipated returns. 

Capitalize on Acquisition Opportunities. We believe that acquisitions enable us to increase cash flow and create long-term stockholder value. Our relationships with corporate 
information technology groups, technology tenants and real estate brokers who are dedicated to serving these tenants provide us with ongoing access to potential acquisitions and 
often enable us to avoid competitive bidding. Furthermore, the specialized nature of technology-related real estate makes it more difficult for traditional real estate investors to 
understand, which results in reduced  

3 

 
 
 
 
Table of Contents 

Index to Financial Statements 

competition for acquisitions relative to other property types. We believe this dynamic creates an opportunity for us to obtain better risk-adjusted returns on our capital. 

• 

• 

• 

Access and Use Capital Efficiently. We believe we can increase stockholder returns by effectively accessing and deploying capital. Since Digital Realty Trust, Inc.’s initial 
public offering in 2004, our company has raised approximately $12.6 billion of capital through common, preferred and convertible preferred equity offerings, exchangeable debt 
offerings, non-exchangeable bond offerings, our global revolving credit facility, our term loan facility, the Prudential shelf facility, secured mortgage financings and refinancings 
and sales of non-core assets. We will endeavor to maintain financial flexibility while using our liquidity and access to capital to support operations, including our acquisition, 
leasing and development programs, which are important sources of our growth. 

Maximize the Cash Flow of Our Properties. We aggressively manage and lease our assets to increase their cash flow. We often acquire properties with substantial in-place 
cash flow and some vacancy, which enables us to create upside through lease-up. Moreover, many of our properties contain extensive in-place infrastructure or buildout that may 
result in higher rents when leased to tenants seeking these improvements. We control our costs by negotiating expense pass-through provisions in tenant leases for operating 
expenses, including power costs and certain capital expenditures. Leases covering approximately 73% of the leased net rentable square feet in our portfolio as of December 31, 
2014 required tenants to pay all or a portion of increases in operating expenses, including real estate taxes, insurance, common area charges and other expenses. 

Leverage Strong Industry Relationships. We use our strong industry relationships with national and regional corporate enterprise information technology groups and 
technology-intensive companies to identify and comprehensively respond to their real estate needs. Our company’s leasing and sales professionals are real estate and technology 
industry specialists who can develop complex facility solutions for the most demanding corporate data center and other technology tenants. 

Competition 

We compete with numerous developers, owners and operators of real estate and datacenters, many of which own properties similar to ours in the same markets in which our properties

are located, including DuPont Fabros Technology, Inc., CoreSite Realty Corporation, CyrusOne Inc., QTS Realty Trust, Inc. and various local developers in the U.S., as well as Global 
Switch Holdings Limited and various regional operators in Europe, Asia and Australia. If our competitors offer space that our tenants or potential tenants perceive to be superior to ours 
based on numerous factors, including available power, security considerations, location, or connectivity, or if they offer rental rates below current market rates, or below the rental rates we 
are offering, we may lose tenants or potential tenants or be required to incur costs to improve our properties or reduce our rental rates. In addition, recently many of our competitors have 
developed additional datacenter space. If the supply of datacenter space continues to increase as a result of these activities or otherwise, rental rates may be reduced or we may face delays 
in leasing or be unable to lease our vacant space, including space that we develop. Finally, if tenants or potential tenants desire services that we do not offer, we may not be able to lease our 
space to those tenants. Our financial condition, results of operations, cash flow, cash available for distribution and ability to satisfy our debt service obligations could be materially 
adversely affected as a result of any or all of these factors. 

Geographic Information 

Operating revenues from properties in the United States were $1.2 billion, $1.1 billion and $1.1 billion and outside the United States were $383.0 million, $349.1 million and $228.9 

million for the years ended December 31, 2014, 2013 and 2012, respectively. We had long-lived assets located in the United States with a net book value of $5.4 billion, $5.6 billion and 
$5.0 billion and outside the United States of $2.7 billion, $2.7 billion and $2.5 billion as of December 31, 2014, 2013 and 2012, respectively. 

Operating revenues from properties located in the United Kingdom were $215.7 million, $197.0 million and $117.2 million, or 13.3%, 13.3% and 9.2% of total operating revenues for 
the years ended December 31, 2014, 2013 and 2012, respectively. No other foreign country comprised more than 10% of total operating revenues for each of these years. We had long-lived 
assets located in the United Kingdom of $1.7 billion, $1.8 billion and $1.7 billion, or 21.3%, 21.1% and 22.3% of total long-lived assets as of December 31, 2014, 2013 and 2012, 
respectively. No other foreign country comprised more than 10% of total long-lived assets as of each of December 31, 2014, 2013 and 2012. See “Risk Factors—Ownership of properties 
located outside of the United States subjects us to foreign currency and related risks which may adversely impact our ability to make distributions”, “—Our international activities are 
subject to unique risks different than those faced by us in the United States and we may not be able to effectively manage our international business” and “—We face risks with our 
international acquisitions associated with investing in unfamiliar markets” for risks relating to our foreign operations.

Regulation 

General 

Office properties in our markets are subject to various laws, ordinances and regulations, including regulations relating to common areas. We believe that each of our properties as of 

December 31, 2014 has the necessary permits and approvals to operate its business. 

Americans With Disabilities Act 

Our properties must comply with Title III of the Americans with Disabilities Act of 1990, or the ADA, to the extent that such properties are “public accommodations” as defined by 
the ADA. The ADA may require removal of structural barriers to access by persons with disabilities in certain public areas of our properties where such removal is readily achievable. We 
believe that our properties are in substantial compliance with the ADA and that we will not be required to make substantial capital expenditures to address the requirements of the ADA. 
However, noncompliance with the ADA could result in imposition of fines or an award of damages to private litigants. The obligation to make readily achievable accommodations is an 
ongoing one, and we will continue to assess our properties and to make alterations as appropriate in this respect. 

Environmental Matters 

Under various laws relating to the protection of the environment, a current or previous owner or operator of real estate may be liable for contamination resulting from the presence or 
discharge of hazardous or toxic substances at that property, and may be required to investigate and clean up such contamination at or emanating from that property. Such laws often impose 
liability without regard to whether the owner or operator knew of, or was responsible for, the presence of the contaminants, and the liability may be joint and several. The Comprehensive 
Environmental Response, Compensation, and Liability Act of 1980, or CERCLA, established a regulatory and remedial program intended to provide for the investigation and clean-up of 
facilities where, or from which, a release of any hazardous substance into the environment has occurred or is threatened. CERCLA’s primary mechanism for remedying such problems is to 
impose strict joint and several liability for clean-up of facilities on current owners and operators of the site, former owners and operators of the site at the time of the disposal of the 
hazardous substances, any person who arranges for the transportation, disposal or treatment of the hazardous substances, and the transporters who select the disposal and treatment facilities, 
regardless of the care exercised by such persons. CERCLA also imposes liability for the cost of evaluating and remedying any damage to natural resources. The costs of CERCLA 
investigation and clean-up can be very substantial. CERCLA also authorizes the imposition of a lien in favor of the United States on all real property subject to, or affected by, a remedial 
action for all costs for which a party is liable. Subject to certain procedural restrictions, CERCLA gives a responsible party the right to bring a contribution action against other responsible 
parties for their allocable shares of investigative and remedial costs. Our ability to obtain reimbursement from others for their allocable shares of such costs would be limited by our ability 
to find other responsible parties and prove the extent of their responsibility, their financial resources, and other procedural requirements. Various state laws also impose strict joint and 
several liability for investigation, clean-up and other damages associated with hazardous substance releases. 

Previous owners used some of our properties for industrial and retail purposes, and those properties may contain some level of environmental contamination. Independent 

environmental consultants have conducted Phase I or similar environmental site assessments on all of the properties in our portfolio. Site assessments are intended to discover and evaluate 
information regarding the environmental condition of the surveyed property and surrounding properties. These assessments do not generally include soil samplings, subsurface 
investigations or an asbestos survey and the assessments may have failed to reveal all environmental conditions, liabilities or compliance concerns. Material environmental conditions, 
liabilities or compliance concerns. In addition, material environmental conditions, liabilities or compliance concerns may have arisen after these reviews were completed or may arise in the 
future. We could be held jointly and severally liable under CERCLA and various state laws for the investigation and remediation of environmental contamination caused by previous 
owners or operators. Fuel storage tanks are present at most of our properties, and if releases were to occur, we may be liable for the costs of cleaning any resulting contamination. The 
presence of contamination or the failure to remediate contamination at our properties may expose us to third-party liability or materially adversely affect our ability to sell, lease or develop 
the real estate or to borrow using the real estate as collateral. 

In addition, some of our tenants, particularly those in the biotechnology and life sciences industry and those in the technology manufacturing industry, routinely handle hazardous 

substances and wastes as part of their operations at our properties. Environmental laws and regulations subject our tenants, and potentially us, to liability resulting from these activities or 
from previous industrial or retail uses of those properties. We could be held jointly and severally liable under CERCLA and various state laws for the investigation and remediation of 
hazardous substances releases by our tenants. Environmental liabilities could also affect a tenant’s ability to make rental payments to us. We cannot assure you that costs of investigation 
and  

5 

 
 
 
Table of Contents 

Index to Financial Statements 

remediation of environmental matters will not affect our ability to pay dividends to Digital Realty Trust, Inc.’s stockholders and distributions to Digital Realty Trust, L.P.’s unitholders or 
that such costs or other remedial measures will not have a material adverse effect on our business, assets or results of operations or our competitive position.  

Our properties and their uses often require permits from various government agencies, including permits related to zoning and land use, such as permits to operate data center 
facilities. Certain permits from state or local environmental regulatory agencies, including regulators of air quality, are usually required to install and operate diesel-powered generators, 
which provide emergency back-up power at most of our facilities. These permits often set emissions limits for certain air pollutants, including oxides of nitrogen. In addition, various 
federal, state, and local environmental, health and safety requirements, such as fire requirements and treated and storm water discharge requirements, apply to some of our properties. 
Changes to applicable regulations, such as air quality regulations, or the permit requirements for equipment at our facilities, could hinder or prevent our construction or operation of data 
center facilities. 

The environmental laws and regulations to which our properties are subject may change in the future, and new laws and regulations may be created. Future laws, ordinances or 

regulations may impose additional material environmental liability. Such laws include those directly regulating our climate change impacts and those which regulate the climate change 
impacts of companies with which we do business, such as utilities providing our facilities with electricity. See “Management’s Discussion and Analysis of Financial Condition and Results 
of Operations-Factors Which May Influence Future Results of Operations-Climate change legislation.” We do not know if or how the requirements will change, but changes may require 
that we make significant unanticipated expenditures, and such expenditures may materially adversely impact our financial condition, cash flow, results, cash available for distributions, 
common stock’s per share trading price, our competitive position and ability to satisfy our debt service obligations. 

Insurance 

We carry comprehensive liability, fire, extended coverage, earthquake, business interruption and rental loss insurance covering all of the properties in our portfolio under a blanket 

policy. We select policy specifications and insured limits which we believe to be appropriate given the relative risk of loss, the cost of the coverage and industry practice and, in the opinion 
of our company’s management, the properties in our portfolio are currently adequately insured. We do not carry insurance for generally uninsured losses such as loss from war or nuclear 
reaction. In addition, we carry earthquake insurance on our properties in an amount and with deductibles which we believe are commercially reasonable. We intend to partially fund the 
earthquake insurance deductibles through a captive insurance company we established in May 2014. Certain of the properties in our portfolio are located in areas known to be seismically 
active.   See “Risk Factors-Risks Related to Our Business and Operations-Potential losses may not be covered by insurance.” 

Employees 

As of December 31, 2014, we had 860 employees. None of these employees are represented by a labor union.

ITEM 1A.    RISK FACTORS 

For purposes of this section, the term “stockholders” means the holders of shares of Digital Realty Trust, Inc.’s common stock and preferred stock. Set forth below are the risks that 

we believe are material to Digital Realty Trust, Inc.’s stockholders and Digital Realty Trust, L.P.’s unitholders. You should carefully consider the following factors in evaluating our 
company, our properties and our business. The occurrence of any of the following risks might cause Digital Realty Trust, Inc.’s stockholders and Digital Realty Trust, L.P.’s unitholders to 
lose all or a part of their investment. Some statements in this report, including statements in the following risk factors, constitute forward-looking statements. Please refer to the section 
entitled “Forward-Looking Statements” starting on page 27. 

Risks Related to Our Business and Operations 

Global economic conditions could adversely affect our liquidity and financial condition. 

In the United States and globally, over the past several years market and economic conditions have been unprecedented and challenging with tighter credit conditions and slower 
economic growth in many markets in which we own properties and conduct our operations. The U.S. and global economies have experienced a recession and face continued concerns about 
the systemic impact of adverse economic conditions, such as high energy costs, geopolitical issues, the availability and cost of credit, unstable global financial and mortgage markets, high 
corporate, consumer and governmental debt levels, high unemployment and declining residential and commercial real estate markets. 

As a result of these conditions, general economic conditions and the cost and availability of capital have been and may again be adversely affected in some or all of the markets in 

which we own properties and conduct our operations. Renewed or increased turbulence in the U.S., European and other international financial markets and economies may adversely affect 
our ability, and the ability of our tenants, to replace or renew maturing liabilities on a timely basis, access the capital markets to meet liquidity and capital expenditure requirements and may 
result in adverse effects on our, and our tenants’, businesses, financial condition and results of operations. 

In addition, our access to funds under our global revolving credit facility depends on the ability of the lenders that are parties to such facilities to meet their funding commitments to 

us. We cannot assure you that long-term disruptions in the global economy and tighter credit conditions among, and potential failures or nationalizations of, third party financial institutions 
as a result of such disruptions will not have an adverse effect on our lenders. If our lenders are not able to meet their funding commitments to us, our business, results of operation, cash 
flows and financial condition could be adversely affected. 

If we do not have sufficient cash flow to continue operating our business and are unable to borrow additional funds, access our existing lines of credit or raise equity or debt capital, 

we may need to find alternative ways to increase our liquidity. Such alternatives may include, without limitation, curtailing development activity, disposing of one or more of our properties 
possibly on disadvantageous terms or entering into or renewing leases on less favorable terms than we otherwise would. 

Our properties depend upon the demand for technology-related real estate. 

Our portfolio of properties consists primarily of technology-related real estate and datacenter real estate in particular. A decrease in the demand for datacenter space, Internet gateway 
facilities or other technology-related real estate would have a greater adverse effect on our business and financial condition than if we owned a portfolio with a more diversified tenant base 
or less specialized use. Our substantial development activities make us particularly susceptible to general economic slowdowns, including recessions, as well as adverse developments in the 
corporate datacenter, Internet and data communications and broader technology industries. Any such slowdown or adverse development could lead to reduced corporate IT spending or 
reduced demand for datacenter space. Reduced demand could also result from business relocations, including to markets that we do not currently serve. Changes in industry practice or in 
technology, such as virtualization technology, more efficient or miniaturization of computing or networking devices, or devices that require higher power densities than today’s devices, 
could also reduce demand for the physical datacenter space we provide or make the tenant improvements in our facilities obsolete or in need of significant upgrades to remain viable. In 
addition, the development of new technologies, the adoption of new industry standards or other factors could render many of our tenants’ current products and services obsolete or 
unmarketable and contribute to a downturn in their businesses, thereby increasing the likelihood that they default under their leases, become insolvent or file for bankruptcy.

Index to Financial Statements 

We may be unable to lease vacant or development space or renew leases, or re-lease space as leases expire. 

At December 31, 2014, we owned approximately 1.3 million square feet of space under active development and approximately 1.2 million square feet of space held for future 
development. We intend to continue to add new space to our development inventory and to continue to develop additional space from this inventory. A portion of the space that we develop 
has been, and may continue to be, developed on a speculative basis, meaning that we do not have a signed lease for the space when we begin the development process. We also develop 
space specifically for tenants pursuant to leases signed prior to beginning the development process. In those cases, if we fail to meet our development obligations under those leases, these 
tenants may be able to terminate the leases and we would be required to find a new tenant for this space. In addition, in certain circumstances we lease data center facilities prior to their 
completion. If we fail to complete the facilities in a timely manner, the tenant may be entitled to terminate its lease, seek damages or penalties against us or pursue other remedies and we 
may be required to find a new tenant for the space. We cannot assure you that once we have developed space or land we will be able to successfully lease it at all, or at rates we consider 
favorable or expected at the time we commenced development. If we are not able to successfully lease the space that we develop, if development costs are higher than we currently 
estimate, or if lease rates are lower than expected when we began the project or are otherwise undesirable, our revenue and operating results could be adversely affected. 

In addition, as of December 31, 2014, leases representing 14.7% of the square footage of the properties in our portfolio, excluding space held for development, were scheduled to 

expire through 2016, and an additional 7.2% of the net rentable square footage, excluding space held for development, was available to be leased. Some of this space may require 
substantial capital investment to meet the power and cooling requirements of today’s advanced data centers, or may no longer be suitable for this use. In addition, we cannot assure you that 
leases will be renewed or that our properties will be re-leased at all, or at net effective rental rates equal to or above the current average net effective rental rates. If the rental rates for our 
properties decrease, our existing tenants do not renew their leases, we do not re-lease our available space, including newly developed space and space for which leases are scheduled to 
expire, or it takes longer for us to lease or re-lease this space or for rents to commence on this space, our financial condition, results of operations, cash flow, cash available for distribution 
and ability to satisfy our debt service obligations could be materially adversely affected. 

Additionally, leasing space in one of our data centers typically involves a significant commitment of resources and due diligence on the part of our customers regarding the adequacy 
of our facilities. As a result, the leasing of data center space can have a long sales cycle, and we may expend significant time and resources in pursuing a particular transaction that may not 
result in revenue. Our inability to adequately manage the risks associated with the sales cycle may adversely affect our business, financial condition and results of operations. 

Our growth depends on external sources of capital which are outside of our control. 

In order for Digital Realty Trust, Inc. to maintain its qualification as a REIT, it is required under the Internal Revenue Code of 1986, as amended, which we refer to as the Code, to 
annually distribute at least 90% of its net taxable income, determined without regard to the dividends paid deduction and excluding any net capital gain. In addition, Digital Realty Trust, 
Inc. will be subject to income tax at regular corporate rates to the extent that it distributes less than 100% of its net taxable income, including any net capital gains. Digital Realty Trust, L.P. 

is required to make distributions to Digital Realty Trust, Inc. that will enable the latter to satisfy this distribution requirement and avoid income and excise tax liability. Because of these 

distribution requirements, we may not be able to fund future capital needs, including any necessary acquisition or development financing, from operating cash flow. Consequently, we rely 
on third-party sources to fund our capital needs. 

Our access to third-party sources of capital depends on a number of factors, including general market conditions, the market’s perception of our business prospects and growth 
potential, our current and expected future earnings, funds from operations and growth thereof, our cash flow and cash distributions, and the market price per share of Digital Realty Trust, 
Inc.’s common stock. We cannot assure you that we will be able to obtain equity or debt financing at all or on terms favorable or acceptable to us. Any additional debt we incur will 
increase our leverage. Further, equity markets have experienced high volatility recently and we cannot assure you that we will be able to raise capital through the sale of equity securities at 
all or on favorable terms. Sales of equity on unfavorable terms could result in substantial dilution to Digital Realty Trust, Inc.’s common stockholders and Digital Realty Trust, L.P.’s 
unitholders. In addition, we may be forced to dispose of one or more of our properties, possibly on disadvantageous terms. 

If we cannot obtain capital from third-party sources, we may not be able to acquire or develop properties when strategic opportunities exist, satisfy our debt service obligations, pay 

cash dividends to Digital Realty Trust, Inc.’s stockholders or make distributions to Digital Realty Trust, L.P.’s unitholders.

Declining real estate valuations and impairment charges could adversely affect our earnings and financial condition. 

We review each of our properties for indicators that its carrying amount may not be recoverable. Examples of such indicators may include a significant decrease in the market price, a 

significant adverse change in the extent or manner the property is being used in its physical condition or expected to be used based on the underwriting at the time of acquisition, an 
accumulation of costs significantly in excess of the amount originally expected for the acquisition or development, a change in our intended holding period due to our intention to sell an 
asset, or a history of operating or cash flow losses. When such impairment indicators exist, we review an estimate of the future undiscounted net cash flows (excluding interest charges) 
expected to result from the real estate investment’s use and eventual disposition and compare to the carrying value of the property. We consider factors such as future operating income, 
trends and prospects, as well as the effects of leasing demand, competition and other factors. If our future undiscounted net cash flow evaluation indicates that we are unable to recover the 
carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property. These losses have a direct 
impact on our net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and 
is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. A worsening real estate 
market may cause us to reevaluate the assumptions used in our impairment analysis. Impairment charges could adversely affect our financial condition, results of operations and cash 
available for distribution. 

We depend on significant tenants, and many of our properties are single-tenant properties or are currently occupied by single tenants. 

As of December 31, 2014, the 20 largest tenants in our property portfolio represented approximately 46% of the total annualized rent generated by our properties. Our largest tenants 
by annualized rent are subsidiaries of CenturyLink, Inc. (Savvis/Qwest), IBM and telx Group, Inc. In 2011, CenturyLink, Inc. acquired Savvis Communications Corporation, or Savvis, and 
Qwest Communications International, Inc., or Qwest, which are our direct tenants. Savvis and Qwest are now wholly-owned subsidiaries of CenturyLink, Inc. CenturyLink, Inc. 
(Savvis/Qwest) leased approximately 2.4 million square feet of net rentable space as of December 31, 2014, representing approximately 7.2% of the total annualized rent generated by our 
properties. In July 2013, IBM acquired SoftLayer Technologies, Inc. Including space leased by SoftLayer, IBM leased approximately 629,000 square feet of net rentable space as of 
December 31, 2014, representing approximately 6.7% of the total annualized rent generated by our properties. telx Group, Inc. leased approximately 341,000 square feet of net rentable 
space as of December 31, 2014, representing approximately 4.2% of the total annualized rent generated by our properties. In addition, 47 of our 131 properties are occupied by single 
tenants, including properties occupied solely by CenturyLink, Inc. (Savvis/Qwest) and IBM. Many factors, including global economic conditions, may cause our tenants to experience a 
downturn in their businesses or otherwise experience a lack of liquidity, which may weaken their financial condition and result in their failure to make timely rental payments or their 
default under their leases. If any tenant defaults or fails to make timely rent payments, we may experience delays in enforcing our rights as landlord and may incur substantial costs in 
protecting our investment. 

Our tenants may choose to develop new data centers or expand their own existing data centers, which could result in the loss of one or more key tenants or reduce demand 

for our newly developed data centers, which could have a material adverse effect on our revenues and results of operations. 

Our tenants may choose to develop new data centers or expand or consolidate into data centers that we do not own in the future. In the event that any of our key tenants were to do so, 

it could result in a loss of business to us or put pressure on our pricing. If we lose a tenant, we cannot assure you that we would be able to replace that tenant at a competitive rate or at all, 
which could have a material adverse effect on our revenues and results of operations. 

The bankruptcy or insolvency of a major tenant may adversely affect the income produced by our properties. 

If any tenant becomes a debtor in a case under the federal Bankruptcy Code, we cannot evict the tenant solely because of the bankruptcy. In addition, the bankruptcy 
court might authorize the tenant to reject and terminate its lease with us. Our claim against the tenant for unpaid, future rent would be subject to a statutory cap that might 
be substantially less than the remaining rent actually owed under the lease. In either case, our claim for unpaid rent would likely not be paid in full. Our revenue and cash 
available for distribution could be materially adversely affected if any of our significant tenants were to become bankrupt or insolvent, or suffer a downturn in its business, 
or fail to renew its lease or renew on terms less favorable to us than its current terms. Net Data Centers, formerly known as Net2EZ, which represented approximately $7.8 
million in annualized base rent for the year ended

Index to Financial Statements 

December 31, 2014, is currently in bankruptcy proceedings. As of February 27, 2015, we had no material tenants in bankruptcy.   

Our portfolio of properties depends upon local economic conditions and is geographically concentrated in certain locations. 

Our portfolio is located in 33 metropolitan areas. Many of these markets experienced downturns in recent years. We depend upon the local economic conditions in these markets, 

including local real estate conditions, and our operations, revenue and cash available for distribution could be materially adversely affected by local economic conditions in these markets. 
Our operations may also be affected if too many competing properties are built in any of these markets or supply otherwise increases or exceeds demand. We cannot assure you that these 
markets will grow or will remain favorable to technology-related real estate. 

As of December 31, 2014, our portfolio, including the 14 properties held as investments in unconsolidated joint ventures, was geographically concentrated in the following 

metropolitan markets.

Annualized rent is monthly contractual rent (defined as cash base rent before abatements) under existing leases as of December 31, 2014, multiplied by 12. The aggregate amount 
of abatements for the year ended December 31, 2014 was approximately $31.1 million. 

In addition, we are currently developing properties in certain of these markets. Any negative changes in real estate, technology or economic conditions in these markets in particular 

could negatively impact our performance. 

Our growth depends upon the successful development of our existing space and developable land and new properties acquired for development and any delays or 

unexpected costs in such development may delay and harm our growth prospects, future operating results and financial condition. 

At December 31, 2014, we had approximately 1.3 million square feet of space under active development and approximately 1.2 million square feet of space held for future 

development, including one vacant property. We have built and may continue to build out a large portion of this space on a speculative basis at significant cost. Our successful development 
of these projects is subject to many risks, including those associated with:

delays in construction;

budget overruns;

fire, flooding, earthquakes and other natural disasters;

geological, construction, excavation and equipment problems; and

delays or denials of entitlements or permits, including zoning and related permits, or other delays resulting from our dependence on the cooperation of public agencies and 
utility companies. 

In addition, while we intend to develop data center properties primarily in markets we are familiar with, we may in the future develop properties in new geographic regions where we 
expect the development of property to result in favorable risk-adjusted returns on our investment. We may not possess the same level of familiarity with the development of other property 
types or other markets, which could adversely affect our ability to develop such properties successfully or at all or to achieve expected performance. 

Development activities, regardless of whether they are ultimately successful, also typically require a substantial portion of our management’s time and attention. This may distract our 

management from focusing on other operational activities of our business. If we are unable to complete development projects successfully, our business may be adversely affected. 

We may be unable to identify and complete acquisitions on favorable terms or at all. 

We continually evaluate the market of available properties and businesses and may acquire additional technology-related real estate when opportunities exist. Our ability to acquire 

properties or businesses on favorable terms may be exposed to the following significant risks: 

• 

• 

• 

• 

we may be unable to acquire a desired property or business because of competition from other real estate investors with significant capital, including both publicly traded 
REITs and institutional investment funds; 

even if we are able to acquire a desired property or business, competition from other potential acquirors may significantly increase the purchase price or result in other less 
favorable terms; 

even if we enter into agreements for the acquisition of technology-related real estate or businesses, these agreements are subject to customary conditions to closing, including 
completion of due diligence investigations to our satisfaction; and 

we may be unable to finance acquisitions on favorable terms or at all.

Additionally, we may acquire properties or businesses subject to liabilities and without any recourse, or with only limited recourse, with respect to unknown or contingent liabilities, 
such as liabilities for clean-up of undisclosed environmental contamination, claims by tenants, vendors or other persons dealing with the former owners of the properties or businesses, tax 
liabilities, claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties or businesses, and other liabilities whether 
incurred in the ordinary course of business or otherwise. The total amount of costs and expenses that we may incur with respect to liabilities associated with acquired properties or 
businesses may exceed our expectations, which may adversely affect our business, financial condition and results of operations. 

Further, we may enter into transactions with limited representations and warranties or with representations and warranties that do not survive the closing of the transactions, in which 

event we would have no or limited recourse against the sellers of such properties or businesses. While we usually require the sellers to indemnify us with respect to breaches of 
representations and warranties that survive, such indemnification is often limited and subject to various materiality thresholds, a significant  

11 

 
 
  
 
Table of Contents 

Index to Financial Statements 

deductible or an aggregate cap on losses. As a result, there is no guarantee that we will recover any amounts with respect to losses due to breaches by the sellers of their representations and 
warranties. Finally, indemnification agreements between us and the sellers typically provide that the sellers will retain certain specified liabilities relating to the properties or businesses 
acquired by us. While the sellers are generally contractually obligated to pay all losses and other expenses relating to such retained liabilities, there can be no guarantee that such 
arrangements will not require us to incur losses or other expenses as well. 

If we cannot complete property or business acquisitions on favorable terms or at all, our financial condition, results of operations, cash flow, cash available for distribution and ability 

to satisfy our debt service obligations could be materially adversely affected. 

We may be unable to successfully integrate and operate acquired properties or businesses. 

Even if we are able to make acquisitions on advantageous terms, our ability to successfully operate them may be exposed to the following significant risks: 

• 

• 

• 

• 

we may spend more than budgeted amounts to make necessary improvements or renovations to acquired properties;

we may be unable to integrate new acquisitions quickly and efficiently, particularly acquisitions of operating businesses or portfolios of properties, into our existing 
operations, and our results of operations and financial condition could be adversely affected; 

acquired properties may be subject to reassessment, which may result in higher than expected property tax payments; and

market conditions may result in higher than expected vacancy rates and lower than expected rental rates.

If we cannot operate acquired properties or businesses to meet our financial expectations, our financial condition, results of operations, cash flow, cash available for distribution and 

ability to satisfy our debt service obligations could be materially adversely affected. 

We may be unable to source off-market deal flow in the future. 

A component of our growth strategy is to continue to acquire additional technology-related real estate. To date, a substantial portion of our acquisitions were acquired before they 
were widely marketed by real estate brokers, or “off-market.” Properties that are acquired off-market are typically more attractive to us as a purchaser because of the absence of competitive 
bidding, which could potentially lead to higher prices. We obtain access to off-market deal flow from numerous sources. If we cannot obtain off-market deal flow in the future, our ability to 
locate and acquire additional properties at attractive prices could be adversely affected. 

We have substantial debt and face risks associated with the use of debt to fund our business activities, including refinancing and interest rate risks. 

Our total consolidated indebtedness at December 31, 2014 was approximately $4.7 billion, and we may incur significant additional debt to finance future acquisition and development 
activities. We have a $2.0 billion global revolving credit facility, which has a borrowing limit that we may increase to up to $2.55 billion, subject to receipt of lender commitments and other 
conditions precedent. At December 31, 2014, approximately $1.4 billion was available under this facility, net of outstanding letters of credit. 

Our substantial indebtedness has important consequences in that it currently requires us to dedicate a significant portion of our cash flow from operations to debt service payments, 
which reduces the availability of our cash flow to fund working capital, capital expenditures, expansion efforts, distributions and other general corporate purposes. Additionally, it could: 
make it more difficult for us to satisfy our obligations with respect to our indebtedness; limit our ability in the future to undertake refinancings of our debt or obtain financing for 
expenditures, acquisitions, development or other general corporate purposes on terms and conditions acceptable to us, if at all; or affect adversely our ability to compete effectively or 
operate successfully under adverse economic conditions. 

In addition, we may violate restrictive covenants or fail to maintain financial ratios specified in our loan documents, which would entitle the lenders to accelerate our debt obligations, 

and our secured lenders or mortgagees may foreclose on our properties or our interests in the entities that own the properties that secure their loans and receive an assignment of rents and 
leases. A foreclosure on one or more of our properties could adversely affect our access to capital, financial condition, results of  

12 

 
 
 
 
Table of Contents 

Index to Financial Statements 

operations, cash flow and cash available for distribution. Further, our default under any one of our loans could result in a cross default on other indebtedness. Furthermore, foreclosures 
could create taxable income without accompanying cash proceeds, a circumstance which could hinder Digital Realty Trust, Inc.’s ability to meet the REIT distribution requirements 
imposed by the Code. 

Additional risks related to our indebtedness are described below. 

We may be unable to refinance our indebtedness at maturity or the refinancing terms may be less favorable than the terms of our original indebtedness. It is likely that we will need 

to refinance at least a portion of our outstanding debt as it matures. If we are unable to refinance or extend principal payments due at maturity or pay them with proceeds of other capital 
transactions, then our cash flow may not be sufficient in all years to repay all such maturing debt and to pay distributions. Further, if prevailing interest rates or other factors at the time of 
refinancing (such as the reluctance of lenders to make commercial real estate loans) result in higher interest rates upon refinancing, then the interest expense relating to that refinanced 
indebtedness would increase. 

Fluctuations in interest rates could materially affect our financial results and may increase the risk our counterparty defaults on our interest rate hedges. Because a significant 

portion of our debt, including debt incurred under our global revolving credit facility, bears interest at variable rates, increases in interest rates could materially increase our interest 
expense. If the United States Federal Reserve increases short-term interest rates, this would have a significant upward impact on shorter-term interest rates, including the interest rates that 
our variable rate debt is based upon. Potential future increases in interest rates and credit spreads may increase our interest expense and therefore negatively affect our financial condition 
and results of operations, and reduce our access to capital markets. We have entered into interest rate swap agreements for a significant portion of our floating rate debt other than the debt 
we incur under our global revolving credit facility. Increased interest rates may increase the risk that the counterparties to our swap agreements will default on their obligations, which could 
further increase our exposure to interest rate fluctuations. Conversely, if interest rates are lower than our swapped fixed rates, we will be required to pay more for our debt than we would 
had we not entered into the swap agreements. 

Adverse changes in our company’s credit ratings could negatively affect our financing activity. The credit ratings of our senior unsecured long-term debt and Digital Realty Trust, 
Inc.’s preferred stock are based on our company’s operating performance, liquidity and leverage ratios, overall financial position and other factors employed by the credit rating agencies in 
their rating analyses of our company. Our company’s credit ratings can affect the amount of capital we can access, as well as the terms and pricing of any debt we may incur. We cannot 
assure you that our company will be able to maintain our current credit ratings, and in the event our current credit ratings are downgraded, we would likely incur higher borrowing costs and 
may encounter difficulty in obtaining additional financing. Also, a downgrade in our company’s credit ratings may trigger additional payments or other negative consequences under our 
current and future credit facilities and debt instruments. For example, if the credit ratings of our senior unsecured long-term debt are downgraded to below investment grade levels, we may 
not be able to obtain or maintain extensions on certain of our existing debt. Adverse changes in our credit ratings could negatively impact our refinancing and other capital market activities, 
our ability to manage our debt maturities, our future growth, our financial condition, the market price of Digital Realty Trust, Inc.’s stock, and our development and acquisition activity. 

Our global revolving credit facility, term loan facility, Prudential shelf facility, 4.50% notes due 2015, 5.875% notes due 2020, 5.250% notes due 2021, 3.625% notes due 2022,4.75% 

notes due 2023 and 4.250% guaranteed notes due 2025 restrict our ability to engage in some business activities. Our global revolving credit facility, term loan facility and Prudential shelf 
facility contain negative covenants and other financial and operating covenants that, among other things: 

• 

• 

• 

• 

• 

restrict our ability to incur additional indebtedness;

restrict our ability to make certain investments;

restrict our ability to merge with another company;

restrict our ability to create, incur or assume liens; and

require us to maintain financial coverage ratios, including with respect to unencumbered assets.

In addition, the global revolving credit facility, the term loan facility and the Prudential shelf facility restrict Digital Realty Trust, Inc. from making distributions to its stockholders, or 

redeeming or otherwise repurchasing shares of its capital stock, after the occurrence and during the continuance of an event of default, except in limited circumstances including as 
necessary to enable Digital Realty Trust, Inc. to maintain its qualification as a REIT and to avoid the payment of income or excise tax. 

13

In addition, our 4.50% notes due 2015, or the 2015 notes, our 5.875% notes due 2020, or the 2020 notes, our 5.250% notes due 2021, or the 2021 notes, our 3.625% notes due 2022, 

or the 2022 notes, our 4.75% notes due 2023, or the 2023 notes, and our 4.250% notes due, or the 2025 notes are governed by indentures, which contain various restrictive covenants, 
including limitations on our ability to incur indebtedness and requirements to maintain a pool of unencumbered assets. These restrictions, and the restrictions in our global revolving credit 
facility, term loan facility, and Prudential shelf facility, could cause us to default on our 2015 notes, 2020 notes, 2021 notes, 2022 notes, 2023 notes, 2025 notes, global revolving credit 
facility, term loan facility or Prudential shelf facility, as applicable, or negatively affect our operations or our ability to pay dividends to Digital Realty Trust, Inc.’s stockholders or 
distributions to Digital Realty Trust, L.P.’s unitholders, which could have a material adverse effect on the market value of Digital Realty Trust, Inc.’s common stock and preferred stock. 

Failure to hedge effectively against interest rate changes may adversely affect results of operations. We seek to manage our exposure to interest rate volatility by using interest rate 

hedging arrangements, such as interest rate cap or swap lock agreements. These agreements involve risks, such as the risk that counterparties may fail to honor their obligations under these 
arrangements, that these arrangements may not be effective in reducing our exposure to interest rate changes and that a court could rule that such an agreement is not legally enforceable. 
Our policy is to use derivatives only to hedge interest rate risks related to our borrowings, not for speculative or trading purposes, and to enter into contracts only with major financial 
institutions based on their credit ratings and other factors. However, we may choose to change this policy in the future. Approximately 80% of our total indebtedness as of December 31, 
2014 was subject to fixed interest rates or variable rates subject to interest rate swaps. We do not currently hedge our global revolving credit facility and as our borrowings under our global 
revolving credit facility increase, so will our percentage of indebtedness not subject to fixed rates and our exposure to interest rates increase. Hedging may reduce the overall returns on our 
investments. Failure to hedge effectively against interest rate changes may materially adversely affect our results of operations. 

Volatility in and regulation of the commercial mortgage-backed securities market has limited and may continue to impact the pricing of secured debt. As a result of the recent crisis in 

the residential mortgage-backed securities markets, the recent global recession, and concerns over the ability to refinance or repay existing commercial mortgage-backed securities as they 
come due, liquidity previously provided by the commercial mortgage-backed securities and collateralized debt obligations markets has significantly decreased. In addition, the Dodd-Frank 
Wall Street Reform and Consumer Protection Act imposes significant new regulations related to the mortgage-backed securities industry and market participants, which has contributed to 
uncertainty in the market. The volatility in the commercial mortgage-backed securities market could result in the following adverse effects on our incurrence of secured debt, which could 
have a materially negative impact on our financial condition, results of operations, cash flow and cash available for distribution: 

• 

• 

• 

• 

higher loan spreads;

tighter loan covenants;

reduced loan to value ratios and resulting borrower proceeds; and

higher amortization and reserve requirements.

We have owned certain of our properties for a limited time. 
We owned 131 properties at December 31, 2014, including 14 properties held as investments in unconsolidated joint ventures and developable land. All of our properties have been 

under our management for less than 11 years. The properties may have characteristics or deficiencies unknown to us that could affect their valuation or revenue potential. We cannot assure 
you that the operating performance of the properties will not decline under our management. 

We may have difficulty managing our growth. 

We have significantly and rapidly expanded the size of our company. Our growth may significantly strain our management, operational and financial resources and systems. In 
addition, as a reporting company, we are subject to the reporting requirements of the Exchange Act and the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act. The requirements of 
these rules and regulations will increase our accounting, legal and financial compliance costs and may strain our management and financial, legal and operational resources and systems. An 
inability to manage our growth effectively or the increased strain on our management of our resources and systems could result in deficiencies in our disclosure controls and procedures or 
our internal control over financial reporting and could negatively impact our cash available for distribution. 

14

Potential losses may not be covered by insurance. 

We currently carry comprehensive liability, property, business interruption, including loss of rental income, and other insurance policies to cover insurable risks to our company. We 

select policy specifications, insured limits and deductibles which we believe to be appropriate and adequate given the relative risk of loss, the cost of the coverage and standard industry 
practices. Our insurance policies contain industry standard exclusions and we do not carry insurance for generally uninsurable perils such as loss from war or nuclear reaction. Although we 
purchase earthquake insurance, it is subject to high deductibles and a significant portion of our properties is located in seismically active zones such as California, which represents 
approximately 19% of our portfolio’s annualized rent as of December 31, 2014. One catastrophic event, for example, in California, could significantly impact multiple properties, the 
aggregate deductible amounts could be significant and the limits we purchase could prove to be insufficient, which could materially and adversely impact our business, financial condition 
and results of operations. Furthermore, a catastrophic regional event could also severely impact some of our insurers rendering them insolvent or unable to fully pay on claims despite their 
current financial strength. In addition, we may discontinue purchasing insurance against earthquake, flood or windstorm or other perils on some or all of our properties in the future if the 
cost of premiums for any of these policies exceeds, in our judgment, the value of the coverage relative to the risk of loss. 

In addition, many of our buildings contain extensive and highly valuable technology-related improvements. Under the terms of our leases, tenants are obligated to maintain adequate 

insurance coverage applicable to such improvements and under most circumstances use their insurance proceeds to restore such improvements after a casualty event. In the event of a 
casualty or other loss involving one of our buildings with extensive installed tenant improvements, our tenants may have the right to terminate their leases if we do not rebuild the base 
building within prescribed times. In such cases, the proceeds from tenants’ insurance will not be available to us to restore the improvements, and our insurance coverage may be insufficient 
to replicate the technology-related improvements made by such tenants. Furthermore, the terms of our mortgage indebtedness at certain of our properties may require us to pay insurance 
proceeds over to our lenders under certain circumstances, rather than use the proceeds to repair the property. If we or one or more of our tenants experiences a loss which is uninsured or 
which exceeds policy limits, we could lose the capital invested in the damaged properties as well as the anticipated future cash flows from those properties. In addition, if the damaged 
properties are subject to recourse indebtedness, we would continue to be liable for the indebtedness, even if these properties were irreparably damaged. 

We face significant competition, which may decrease or prevent increases of the occupancy and rental rates of our properties. 

We compete with numerous developers, owners and operators of real estate and datacenters, many of which own properties similar to ours in the same markets in which our properties

are located, including DuPont Fabros Technology, Inc., CoreSite Realty Corporation, CyrusOne Inc., QTS Realty Trust, Inc. and various local developers in the U.S., as well as Global 
Switch Holdings Limited and various regional operators in Europe, Asia and Australia. In addition, we may in the future face competition from new entrants into the datacenter market, 
including new entrants who may acquire our current competitors. Some of our competitors and potential competitors have significant advantages over us, including greater name 
recognition, longer operating histories, pre-existing relationships with current or potential customers, significantly greater financial, marketing and other resources and more ready access to 
capital which allow them to respond more quickly to new or changing opportunities. If our competitors offer space that our tenants or potential tenants perceive to be superior to ours based 
on numerous factors, including available power, security considerations, location, or connectivity, or if they offer rental rates below current market rates, or below the rental rates we are 
offering, we may lose tenants or potential tenants or be required to incur costs to improve our properties or reduce our rental rates. In addition, recently many of our competitors have 
developed and continue to develop additional datacenter space. If the supply of datacenter space continues to increase as a result of these activities or otherwise, rental rates may be reduced 
or we may face delays in leasing or be unable to lease our vacant space, including space that we develop. 

Further, if tenants or potential tenants desire services that we do not offer, we may not be able to lease our space to those tenants. Our financial condition, results of operations, cash 

flow, cash available for distribution and ability to satisfy our debt service obligations could be materially adversely affected as a result of any or all of these factors. 

Joint venture investments could be adversely affected by our lack of sole decision-making authority, our reliance on co-venturers’ financial condition and disputes between 

us and our co-venturers. 

We currently, and may in the future, co-invest with third parties through partnerships, joint ventures or other entities, acquiring non-controlling interests in or sharing responsibility 
for managing the affairs of a property, partnership, joint venture or other entity. In these events, we are not in a position to exercise sole decision-making authority regarding the property, 
partnership, joint venture or other entity. Investments in partnerships, joint ventures, or other entities may, under certain  

15 

 
 
  
 
Table of Contents 

Index to Financial Statements 

circumstances, involve risks not present when a third party is not involved, including the possibility that partners or co-venturers might become bankrupt or fail to fund their share of 
required capital contributions. Partners or co-venturers 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 would require us to dispose of the joint 
venture asset or transfer it to a taxable REIT subsidiary in order for Digital Realty Trust, Inc. to maintain its status as a REIT. Such investments may also lead to impasses, for example, as 
to whether to sell a property, because neither we nor the partner or co-venturer would have full control over the partnership or joint venture. Disputes between us and partners or co-
venturers may result in litigation or arbitration that would increase our expenses and prevent our officers and/or directors from focusing their time and effort on our day-to-day business. 
Consequently, actions by or disputes with partners or co-venturers may subject properties owned by the partnership or joint venture to additional risk. In addition, we may in certain 
circumstances be liable for the actions of our third-party partners or co-venturers. 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 success depends on key personnel whose continued service is not guaranteed. 

We depend on the efforts of key personnel of our company, particularly A. William Stein, Digital Realty Trust, Inc.’s Chief Executive Officer and Chief Financial Officer and Scott 

Peterson, Digital Realty Trust, Inc.’s Chief Investment Officer. They are important to our success for many reasons, including that each has a national or regional reputation in our industry 
and the investment community that attracts investors and business and investment opportunities and assists us in negotiations with investors, lenders, existing and potential tenants and 
industry personnel. If we lost their services, our business and investment opportunities and our relationships with lenders and other capital markets participants, existing and prospective 
tenants and industry personnel could suffer. Many of our company’s other senior employees also have strong technology, finance and real estate industry reputations. As a result, we have 
greater access to potential acquisitions, financing, leasing and other opportunities, and are better able to negotiate with tenants. As the number of our competitors increases, it becomes more 
likely that a competitor would attempt to hire certain of these individuals away from our company. The loss of any of these key personnel would result in the loss of these and other benefits 
and could materially and adversely affect our results of operations. 

Our properties may not be suitable for lease to datacenter or traditional technology office tenants without significant expenditures or renovations. 

Because many of our properties contain tenant improvements installed at our tenants’ expense, they may be better suited for a specific corporate enterprise datacenter user or 
technology industry tenant and could require significant modification in order for us to re-lease vacant space to another corporate enterprise datacenter user or technology industry tenant. 
The tenant improvements may also become outdated or obsolete as the result of technological change, the passage of time or other factors. In addition, our development space will generally 
require substantial improvement to be suitable for datacenter use. For the same reason, our properties also may not be suitable for lease to traditional office tenants without significant 
expenditures or renovations. As a result, we may be required to invest significant amounts or offer significant discounts to tenants in order to lease or re-lease that space, either of which 
could adversely affect our financial and operating results. 

Our data center infrastructure may become obsolete, and we may not be able to upgrade our power and cooling systems cost-effectively, or at all. 

Our data center infrastructure may become obsolete due to the development of new systems to deliver power to or eliminate heat in our facilities. Additionally, our data center 
infrastructure could become obsolete as a result of the development of new server technology that does not require the levels of critical load and heat removal that our facilities are designed 
to provide and could be run less expensively on a different platform. In addition, our power and cooling systems are difficult and expensive to upgrade. Accordingly, we may not be able to 
efficiently upgrade or change these systems to meet new demands without incurring significant costs that we may not be able to pass on to our customers which could adversely impact our 
business, financial condition and results of operations. 

Ownership of properties located outside of the United States subjects us to foreign currency and related risks which may adversely impact our ability to make distributions. 

We owned 28 properties located outside of the United States at December 31, 2014. In addition, we are currently considering, and will in the future consider, additional international 

acquisitions. 

The ownership of properties located outside of the United States subjects us to risk from fluctuations in exchange rates between foreign currencies and the U.S. dollar. We expect that 

our principal foreign currency exposure will be to the British  

16 

 
 
 
Table of Contents 

Index to Financial Statements 

Pound and the Euro. Changes in the relation of these currencies to the U.S. dollar will affect our revenues and operating margins, may materially adversely impact our financial condition, 
results of operations, cash flow, cash available for distribution and ability to satisfy our debt obligations. 

We may attempt to mitigate some or all of the risk of currency fluctuation by financing our properties in the local currency denominations, although we cannot assure you that we will 

be able to do so or that this will be effective. We may also engage in direct hedging activities to mitigate the risks of exchange rate fluctuations in a manner consistent with our 
qualifications as a REIT, although we cannot assure you that we will be able to do so or that this will be effective. 

Our international activities are subject to unique risks different than those faced by us in the United States and we may not be able to effectively manage our international 

business. 

We have acquired and developed, and may continue to acquire and develop, properties outside the United States. Our foreign operations involve risks not generally associated with 

investments in the United States, including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

our limited knowledge of and relationships with sellers, tenants, contractors, suppliers or other parties in these markets;

complexity and costs associated with managing international development and operations;

difficulty in hiring qualified management, sales and construction personnel and service providers in a timely fashion;

differing employment practices and labor issues;

multiple, conflicting and changing legal, regulatory, entitlement and permitting, and tax and treaty environments;

exposure to increased taxation, confiscation or expropriation;

currency transfer restrictions and limitations on our ability to distribute cash earned in foreign jurisdictions to the United States;

difficulty in enforcing agreements in non-U.S. jurisdictions, including those entered into in connection with our acquisitions or in the event of a default by one or more of our 
tenants, suppliers or contractors; 

local business and cultural factors; and

political and economic instability, including sovereign credit risk, in certain geographic regions.

Our inability to overcome these risks could adversely affect our foreign operations and could harm our business and results of operations. 

We face risks with our international acquisitions associated with investing in unfamiliar markets. 

We have acquired and may continue to acquire properties on a strategic and selective basis in international markets that are new to us. When we acquire properties located in these 

markets, we may face risks associated with a lack of market knowledge or understanding of the local economy and culture, forging new business relationships in the area and unfamiliarity 
with local government and permitting procedures. In addition, due diligence, transaction and structuring costs may be higher than those we may face in the United States. We work to 
mitigate such risks through extensive diligence and research and associations with experienced partners; however, we cannot assure you that all such risks will be eliminated. 

Future consolidation in the technology industry could materially adversely affect our revenues by eliminating some of our potential tenants and could make us more 

dependent on a more limited number of tenants. 

Mergers or consolidations of technology companies in the future could reduce the number of our tenants and potential tenants. If our tenants merge with or are acquired by other 

entities that are not our tenants, they may discontinue or reduce the use of our data centers in the future. Any of these developments could have a material adverse effect on our revenues 
and results of operations. 

We depend on third parties to provide Internet connectivity to the tenants in our data centers and any delays or disruptions in connectivity may materially adversely affect 

our operating results and cash flow. 

We are not a telecommunications carrier. Although our tenants generally are responsible for providing their own network connectivity, we still depend upon the presence of 
telecommunications carriers’ fiber networks serving the locations of our data centers in order to attract and retain tenants. We believe that the availability of carrier capacity will directly 
affect our ability to achieve our projected results. Any carrier may elect not to offer its services within our data centers. Any carrier that has decided to provide Internet connectivity to our 
data centers may not continue to do so for any period of time. Further, some carriers are  

17 

 
 
 
Table of Contents 

Index to Financial Statements 

experiencing business difficulties or have announced consolidations. As a result, some carriers may be forced to downsize or terminate connectivity within our data centers, which could 
have an adverse effect on the business of our tenants and, in turn, our own operating results. 

Our new data centers require construction and operation of a sophisticated redundant fiber network. The construction required to connect multiple carrier facilities to our data centers 

is complex and involves factors outside of our control, including regulatory requirements and the availability of construction resources. We have started to obtain the right to use network 
resources owned by other companies, including rights to use dark fiber, in order to attract telecommunications carriers and customers to our portfolio. If the establishment of highly diverse 
Internet connectivity to our data centers does not occur, is materially delayed or is discontinued, or is subject to failure, our operating results and cash flow may be materially adversely 
affected. Additionally, any hardware or fiber failures on this network may result in significant loss of connectivity to our data centers. This could negatively affect our ability to attract new 
tenants or retain existing tenants, which could have an adverse effect on our business, financial condition and results of operations. 

Any failure of our physical infrastructure or services could lead to significant costs and disruptions that could harm our business reputation and could adversely affect our 

earnings and financial condition. 

Our business depends on providing customers with highly reliable service, including with respect to power supply, security and maintenance of environmental conditions. We may 
fail to provide such service as a result of numerous factors, including mechanical failure, power outage, human error, physical or electronic security breaches, war, terrorism and related 
conflicts or similar events worldwide, fire, earthquake, hurricane, flood and other natural disasters, sabotage and vandalism. 

Problems at one or more of our data centers, whether or not within our control, could result in service interruptions or equipment damage. Substantially all of our customer leases 
include terms requiring us to meet certain service level commitments to our customers. Any failure to meet these commitments or any equipment damage in our data centers, including as a 
result of mechanical failure, power outage, human error or other reasons, could subject us to liability under our lease terms, including service level credits against customer rent payments, 
or, in certain cases of repeated failures, the right by the customer to terminate the lease. Service interruptions, equipment failures or security breaches may also expose us to additional legal 
liability and damage our brand and reputation, and could cause our customers to terminate or not renew their leases. In addition, we may be unable to attract new customers if we have a 
reputation for service disruptions, equipment failures or physical or electronic security breaches in our data centers. Any such failures could adversely affect our business, financial 
condition and results of operations. 

We are dependent upon third-party suppliers for power and certain other services, and we are vulnerable to service failures of our third-party suppliers and to price 

increases by such suppliers. 

We rely on third parties to provide power to our data centers, and we cannot ensure that these third parties will deliver such power in adequate quantities or on a consistent basis. If 

the amount of power available to us is inadequate to support our customer requirements, we may be unable to satisfy our obligations to our customers or grow our business. In addition, our 
data centers may be susceptible to power shortages and planned or unplanned power outages caused by these shortages. Power outages may last beyond our backup and alternative power 
arrangements, which would harm our customers and our business. Any loss of services or equipment damage could adversely affect both our ability to generate revenues and our operating 
results, and harm our reputation. 

In addition, we may be subject to risks and unanticipated costs associated with obtaining power from various utility companies. Utilities that serve our data centers may be dependent 
on, and sensitive to price increases for, a particular type of fuel, such as coal, oil or natural gas. In addition, the price of these fuels and the electricity generated from them could increase as 
a result of proposed legislative measures related to climate change or efforts to regulate carbon emissions. Increases in the cost of power at any of our data centers would put those locations 
at a competitive disadvantage relative to data centers served by utilities that can provide less expensive power. 

Even if we have additional space available for lease at any one of our data centers, our ability to lease this space to existing or new customers could be constrained by our 

ability to provide sufficient electrical power. 

As current and future customers increase their power footprint in our facilities over time, the corresponding reduction in available power could limit our ability to increase occupancy 

rates or network density within our existing facilities. Furthermore, at certain of our data centers, our aggregate maximum contractual obligation to provide power and cooling to our 
customers may exceed the physical capacity at such data centers if customers were to quickly increase their demand for power and cooling. If we are not able to increase the available 
power and/or cooling or move the customer to another location within  

18 

 
 
 
Table of Contents 

Index to Financial Statements 

our data centers with sufficient power and cooling to meet such demand, we could lose the customer as well as be exposed to liability under our leases. In addition, our power and cooling 
systems are difficult and expensive to upgrade. Accordingly, we may not be able to efficiently upgrade or change these systems to meet new demands without incurring significant costs 
that we may not be able to pass on to our customers. Any such material loss of customers, liability or additional costs could adversely affect our business, financial condition and results of 
operations. 

We may be vulnerable to breaches of our physical security, or to unauthorized access to or disruption of our customers’ networks or our information technology systems, 

any of which could disrupt our operations and have a material adverse effect on our revenues and results of operations. 

We use a variety of procedures and systems to maintain the physical security of our facilities. Any failure of these systems, whether caused by human error, third party attack, 

employee malfeasance, system error, utility failure or some other cause could result in, among other things, a breach of our customers’ networks, a breach of our obligations under our 
customer leases, the misappropriation of our or our customers’ or their customers’ proprietary information, or interruptions or malfunctions in our or our customers’ operations. We rely 
upon our information technology systems to manage customer relationships, maintain access lists and to maintain our financial and other business information. Unauthorized access to or 
disruption of these systems could result in, among other things, unauthorized access to our facilities, delays or interruptions to our ability to meet customer needs, breach of our legal or 
contractual obligations or inability to access or rely upon critical business records. We may be required to expend significant financial resources to protect against or to alleviate breaches of 
physical security, network breaches as well as unauthorized access to or disruption of our customers’ networks or our information technology systems. We may not be able to implement 
physical or technical security measures in a timely manner or, if and when implemented, these measures could be circumvented. Any breaches that may occur could expose us to increased 
risk of lawsuits, loss of existing or potential customers, harm to our reputation and increases in our security costs, which could have a material adverse effect on our revenues and results of 
operations. 

Illiquidity of real estate investments could significantly impede our ability to respond to adverse changes in the performance of our properties and harm our financial 

condition. 

Because real estate investments are relatively illiquid and because there may be even fewer buyers for our specialized real estate, our ability to promptly sell properties in our portfolio 

in response to adverse changes in their performance may be limited, which may harm our financial condition. Further, Digital Realty Trust, Inc. is subject to provisions in the Code that 
limit a REIT’s ability to dispose of properties, which limitations are not applicable to other types of real estate companies. While Digital Realty Trust, Inc. has exclusive authority under 
Digital Realty Trust, L.P.’s limited partnership agreement to determine whether, when, and on what terms to sell a property, any such decision would require the approval of Digital Realty 
Trust, Inc.’s board of directors. See “Risks Related to Our Organizational Structure—Tax consequences upon sale or refinancing.” These limitations may affect our ability to sell properties. 
This lack of liquidity and the Code restrictions may limit our ability to vary our portfolio promptly in response to changes in economic or other conditions and, as a result, could adversely 
affect our financial condition, results of operations, cash flow, cash available for distribution and ability to access capital necessary to meet our debt payments and other obligations. 

We could incur significant costs related to government regulation and private litigation over environmental matters, including existing conditions at some of our properties. 

Under various laws relating to the protection of the environment, a current or previous owner or operator of real estate may be liable for contamination resulting from the presence or 

discharge of hazardous or toxic substances at a property, and may be required to investigate and clean up such contamination at or emanating from a property. Such laws often impose 
liability without regard to whether the owner or operator knew of, or was responsible for, the presence of the contaminants, and the liability may be joint and several. The Comprehensive 
Environmental Response, Compensation, and Liability Act of 1980, or CERCLA, established a regulatory and remedial program intended to provide for the investigation and clean-up of 
facilities where, or from which, a release of any hazardous substance into the environment has occurred or is threatened. CERCLA’s primary mechanism for remedying such problems is to 
impose strict joint and several liability for clean-up of facilities on current owners and operators of the site, former owners and operators of the site at the time of the disposal of the 
hazardous substances, any person who arranges for the transportation, disposal or treatment of the hazardous substances, and the transporters who select the disposal and treatment facilities, 
regardless of the care exercised by such persons. CERCLA also imposes liability for the cost of evaluating and remedying any damage to natural resources. The costs of CERCLA 
investigation and clean-up can be very substantial. CERCLA also authorizes the imposition of a lien in favor of the United States on all real property subject to, or affected by, a remedial 
action for all costs for which a party is liable. Subject to certain procedural restrictions, CERCLA gives a responsible party the right to bring a contribution action against other responsible  

19 

 
 
 
 
Table of Contents 

Index to Financial Statements 

parties for their allocable shares of investigative and remedial costs. Our ability to obtain reimbursement from others for their allocable shares of such costs would be limited by our ability 
to find other responsible parties and prove the extent of their responsibility, their financial resources, and other procedural requirements. Various state laws also impose strict joint and 
several liability for investigation, clean-up and other damages associated with hazardous substance releases.  

Previous owners used some of our properties for industrial and retail purposes, so those properties may contain some level of environmental contamination. Independent 

environmental consultants have conducted Phase I or similar environmental site assessments on all of the properties in our portfolio. Site assessments are intended to discover and evaluate 
information regarding the environmental condition of the surveyed property and surrounding properties. These assessments do not generally include soil samplings, subsurface 
investigations or an asbestos survey and the assessments may fail to reveal all environmental conditions, liabilities or compliance concerns. In addition, material environmental conditions, 
liabilities or compliance concerns may have arisen after these reviews were completed or may arise in the future. We could be held jointly and severally liable under CERCLA and various 
state laws for the investigation and remediation of environmental contamination caused by previous owners or operators. Fuel storage tanks are present at most of our properties, and if 
releases were to occur, we may be liable for the costs of cleaning any resulting contamination. The presence of contamination or the failure to remediate contamination at our properties 
may expose us to third-party liability or materially adversely affect our ability to sell, lease or develop the real estate or to borrow using the real estate as collateral. 

In addition, some of our tenants, particularly those in the biotechnology and life sciences industry and those in the technology manufacturing industry, routinely handle hazardous 

substances and wastes as part of their operations at our properties. Environmental laws and regulations subject our tenants, and potentially us, to liability resulting from these activities or 
from previous industrial or retail uses of those properties. We could be held jointly and severally liable under CERCLA and various state laws for the investigation and remediation of 
hazardous substances releases by our tenants. Environmental liabilities could also affect a tenant’s ability to make rental payments to us. We cannot assure you that costs of investigation 
and remediation of environmental matters will not affect our ability to pay dividends to Digital Realty Trust, Inc.’s stockholders and distributions to Digital Realty Trust, L.P.’s unitholders 
or that such costs or other remedial measures will not have a material adverse effect on our business, assets or results of operations. 

Some of the properties may contain asbestos-containing building materials. Environmental laws require that asbestos-containing building materials be properly managed and 
maintained, and may impose fines and penalties on building owners or operators for failure to comply with these requirements. These laws may also allow third parties to seek recovery 
from owners or operators for personal injury associated with exposure to asbestos-containing building materials. 

Our properties and their uses often require permits from various government agencies, including permits related to zoning and land use, such as permits to operate data center 
facilities. Certain permits from state or local environmental regulatory agencies, including regulators of air quality, are usually required to install and operate diesel-powered generators, 
which provide emergency back-up power at most of our facilities. These permits often set emissions limits for certain air pollutants, including oxides of nitrogen. In addition, various 
federal, state, and local environmental, health and safety requirements, such as fire requirements and treated and storm water discharge requirements, apply to some of our properties. 
Changes to applicable regulations, such as air quality regulations, or the permit requirements for equipment at our facilities, could hinder or prevent our construction or operation of data 
center facilities. 

The environmental laws and regulations to which our properties are subject may change in the future, and new laws and regulations may be created. Future laws, ordinances or 
regulations may impose additional material environmental liability. Such laws include those directly regulating our climate change impacts and those which regulate the climate change 
impacts of companies with which we do business, such as utilities providing our facilities with electricity. See “Management’s Discussion and Analysis of Financial Condition and Results 
of Operations-Factors Which May Influence Future Results of Operations-Climate change legislation.” We do not know if or how the requirements will change, but changes may require 
that we make significant unanticipated expenditures, and such expenditures may materially adversely impact our financial condition, cash flow, results, cash available for distributions, 
common stock’s per share trading price, our competitive position and ability to satisfy our debt service obligations.  

Our properties may contain or develop harmful mold or suffer from other air quality issues, which could lead to liability for adverse health effects and costs to remedy the 

problem. 

When excessive moisture accumulates in buildings or on building materials, mold may grow, particularly if the moisture problem remains undiscovered or is not addressed over a 
period of time. Some molds may produce airborne toxins or irritants. Indoor air quality issues can also stem from inadequate ventilation, chemical contamination from indoor or outdoor 
sources and  

20 

 
 
 
 
 
 
 
 
 
Table of Contents 

Index to Financial Statements 

other biological contaminants such as pollen, viruses and bacteria. Indoor exposure to airborne toxins or irritants above certain levels can be alleged to cause a variety of adverse health 
effects and symptoms, including allergic or other reactions. As a result, the presence of significant mold or other airborne contaminants at any of our properties could require us to 
undertake a costly remediation program to contain or remove the mold or other airborne contaminants from the affected property or increase indoor ventilation. In addition, the presence of 
significant mold or other airborne contaminants could expose us to liability from our tenants, employees of our tenants and others if property damage or health concerns arise. 

We may incur significant costs complying with the Americans with Disabilities Act and similar laws. 

Under the Americans with Disabilities Act of 1990, or the ADA, all public accommodations must meet federal requirements related to access and use by disabled persons. We have 
not conducted an audit or investigation of all of our properties to determine our compliance with the ADA. If one or more of the properties in our portfolio does not comply with the ADA, 
then we would be required to incur additional costs to bring the property into compliance. Additional federal, state and local laws also may require modifications to our properties, or 
restrict our ability to renovate our properties. We cannot predict the ultimate cost of compliance with the ADA or other legislation. If we incur substantial costs to comply with the ADA 
and any other similar legislation, our financial condition, results of operations, cash flow, cash available for distribution and ability to satisfy our debt service obligations could be materially 
adversely affected. 

We may incur significant costs complying with other regulations. 

The properties in our portfolio are subject to various federal, state and local regulations, such as state and local fire and life safety regulations. If we fail to comply with these various 
regulations, we may have to pay fines or private damage awards. In addition, we do not know whether existing regulations will change or whether future regulations will require us to make 
significant unanticipated expenditures that will materially adversely impact our financial condition, results of operations, cash flow, cash available for distribution and ability to satisfy our 
debt service obligations. 

The conversion rights of Digital Realty Trust, Inc.’s preferred stock may be detrimental to holders of Digital Realty Trust, Inc.’s common stock. 

Digital Realty Trust, Inc. currently has 11,500,000 shares of 7.000% series E cumulative redeemable preferred stock outstanding, 7,300,000 shares of 6.625% series F cumulative 
redeemable preferred stock outstanding, 10,000,000 shares of 5.875% series G cumulative redeemable preferred stock outstanding and 14,600,000 shares of 7.375% series H cumulative 
redeemable preferred stock outstanding, which may be converted into Digital Realty Trust, Inc. common stock upon the occurrence of limited specified change in control transactions. The 
conversion of series E preferred stock, series F preferred stock, series G preferred stock or series H preferred stock for Digital Realty Trust, Inc. common stock would dilute stockholder 
ownership in Digital Realty Trust, Inc. and unitholder ownership in Digital Realty Trust, L.P., and could adversely affect the market price of Digital Realty Trust, Inc. common stock and 
could impair our ability to raise capital through the sale of additional equity securities. 

Our Digital Design Services® business is subject to risks particular to third-party construction projects.

Our Digital Design Services® business is new and we only have limited experience in providing design and construction services to third parties. By providing these design and 
construction services to third parties, we become subject to a variety of risks unique to these activities. If construction costs of a project exceed original estimates, such costs may have to be 
absorbed by us, which would make the project less profitable than originally estimated, or possibly not profitable at all. A construction project may be delayed due to government or 
regulatory approvals, supply shortages, or other events and circumstances beyond our control, or the time required to complete a construction project may be greater than originally 
anticipated. In addition, we may be liable for any injuries or damage that arise from worksite accidents, or from the design or construction of the datacenters we build. If any such excess 
costs, project delays or liabilities were to be material, such events may adversely affect our financial condition, results of operations and cash available for distribution. 

Our business could be adversely impacted if there are deficiencies in our disclosure controls and procedures or internal control over financial reporting. 

The design and effectiveness of our disclosure controls and procedures and internal control over financial reporting may not prevent all errors, misstatements or misrepresentations. 

While management will continue to review the effectiveness of our disclosure controls and procedures and internal control over financial reporting, there can be no guarantee that our 
internal control over financial reporting will be effective in accomplishing all control objectives all of the time. Furthermore, our disclosure controls and procedures and internal control 
over financial reporting with respect to entities that we do not control or  

21 

 
 
 
 
Table of Contents 

Index to Financial Statements 

manage may be substantially more limited than those we maintain with respect to the subsidiaries that we have controlled or managed over the course of time. Deficiencies, including any 
material weakness, in our internal control over financial reporting which may occur in the future could result in misstatements of our results of operations, restatements of our financial 
statements, a decline in Digital Realty Trust, Inc.’s stock price, or otherwise materially adversely affect our business, reputation, results of operations, financial condition or liquidity. 

Risks Related to Our Organizational Structure 

Digital Realty Trust, Inc.’s duty to its stockholders may conflict with the interests of Digital Realty Trust, L.P.’s unitholders. 

Conflicts of interest may exist or could arise in the future as a result of the relationships between Digital Realty Trust, Inc. and its affiliates, on the one hand, and our operating 
partnership or any partner thereof, on the other. Digital Realty Trust, Inc.’s directors and officers have duties to Digital Realty Trust, Inc. and its stockholders under Maryland law in 
connection with their management of our company. At the same time, Digital Realty Trust, Inc., as general partner, has fiduciary duties under Maryland law to our operating partnership 
and to the limited partners in connection with the management of our operating partnership. Digital Realty Trust, Inc.’s duties as general partner to our operating partnership and its partners 
may come into conflict with the duties of Digital Realty Trust, Inc.’s directors and officers to Digital Realty Trust, Inc. and its stockholders. Under Maryland law, a general partner of a 
Maryland limited partnership owes its limited partners the duties of loyalty and care, which must be discharged consistently with the obligation of good faith and fair dealing, unless the 
partnership agreement provides otherwise. The partnership agreement of our operating partnership provides that for so long as Digital Realty Trust, Inc. owns a controlling interest in our 
operating partnership, any conflict that cannot be resolved in a manner not adverse to either Digital Realty Trust, Inc.’s stockholders or the limited partners will be resolved in favor of 
Digital Realty Trust, Inc.’s stockholders. 

The provisions of Maryland law that allow the fiduciary duties of a general partner to be modified by a partnership agreement have not been tested in a court of law, and we have not 

obtained an opinion of counsel covering the provisions set forth in the partnership agreement that purport to waive or restrict Digital Realty Trust, Inc.’s fiduciary duties. 

Digital Realty Trust, Inc.’s stockholders and Digital Realty Trust, L.P.’s unitholders are also subject to the following additional conflict of interest: 

Tax consequences upon sale or refinancing. Sales of properties and repayment of certain indebtedness will affect holders of common units in our operating partnership and Digital 
Realty Trust, Inc.’s stockholders differently. Consequently, these holders of common units in our operating partnership may have different objectives regarding the appropriate pricing and 
timing of any such sale or repayment of debt. While Digital Realty Trust, Inc. has exclusive authority under the limited partnership agreement of our operating partnership to determine 
when to refinance or repay debt or whether, when, and on what terms to sell a property, any such decision would require the approval of Digital Realty Trust, Inc.’s board of directors. 
Certain of Digital Realty Trust, Inc.’s directors and executive officers could exercise their influence in a manner inconsistent with the interests of some, or a majority, of Digital Realty 
Trust, L.P.’s unitholders, including in a manner which could prevent completion of a sale of a property or the repayment of indebtedness. 

Digital Realty Trust, Inc.’s charter, Digital Realty Trust, L.P.’s partnership agreement and Maryland law contain provisions that may delay, defer or prevent a change of 

control transaction. 

Digital Realty Trust, Inc.’s charter and the articles supplementary with respect to the preferred stock contain 9.8% ownership limits. Digital Realty Trust, Inc.’s charter, subject to 
certain exceptions, authorizes the company’s directors to take such actions as are necessary and desirable to preserve the company’s qualification as a REIT and to limit any person to actual 
or constructive ownership of no more than 9.8% (by value or by number of shares, whichever is more restrictive) of the outstanding shares of the company’s common stock, 9.8% (by value 
or by number of shares, whichever is more restrictive) of the outstanding shares of any series of preferred stock and 9.8% of the value of the company’s outstanding capital stock. Digital 
Realty Trust, Inc.’s board of directors, in its sole discretion, may exempt (prospectively or retroactively) a proposed transferee from the ownership limit. However, Digital Realty Trust, 
Inc.’s board of directors may not grant an exemption from the ownership limit to any proposed transferee whose direct or indirect ownership of more than 9.8% of the outstanding shares of 
the company’s common stock, more than 9.8% of the outstanding shares of any series of preferred stock or more than 9.8% of the value of the company’s outstanding capital stock could 
jeopardize the company’s status as a REIT. These restrictions on transferability and ownership will not apply if Digital Realty Trust, Inc.’s board of directors determines that it is no longer 
in the company’s best interests to attempt to qualify, or to continue to qualify, as a REIT or that compliance is no longer required for  

22

Index to Financial Statements 

REIT qualification. The ownership limit may delay, defer or prevent a transaction or a change of control that might be in the best interest of Digital Realty Trust, Inc.’s stockholders and 
Digital Realty Trust, L.P.’s unitholders. 

Digital Realty Trust, L.P.’s partnership agreement contains provisions that may delay, defer or prevent a change of control transaction. Digital Realty Trust, L.P.’s partnership 
agreement provides that Digital Realty Trust, Inc. may not engage in any merger, consolidation or other combination with or into another person, any sale of all or substantially all of its 
assets or any reclassification, recapitalization or change of its outstanding equity interests unless the transaction is approved by the holders of common units and long term incentive units 
representing at least 35% of the aggregate percentage interests of all holders of common units and long-term incentive units and either: 

• 

all limited partners will receive, or have the right to elect to receive, for each common unit an amount of cash, securities or other property equal to the product of the number 
of shares of Digital Realty Trust, Inc. common stock into which a common unit is then exchangeable and the greatest amount of cash, securities or other property paid in 
consideration of each share of Digital Realty Trust, Inc. common stock in connection with the transaction (provided that, if, in connection with the transaction, a purchase, 
tender or exchange offer is made to and accepted by the holders of more than 50% of the shares of Digital Realty Trust, Inc. common stock, each holder of common units will 
receive, or have the right to elect to receive, the greatest amount of cash, securities or other property which such holder would have received if it exercised its right to 
redemption and received shares of Digital Realty Trust, Inc. common stock in exchange for its common units immediately prior to the expiration of such purchase, tender or 
exchange offer and thereupon accepted such purchase, tender or exchange offer and the transaction was then consummated); or 

• 

the following conditions are met:

• 

• 

• 

• 

substantially all of the assets directly or indirectly owned by the surviving entity in the transaction are held directly or indirectly by Digital Realty Trust, L.P. or 
another limited partnership or limited liability company which is the survivor of a merger, consolidation or combination of assets with Digital Realty Trust, 
L.P., or the surviving partnership; 

the holders of common units and long-term incentive units own a percentage interest of the surviving partnership based on the relative fair market value of 
Digital Realty Trust, L.P.’s net assets and the other net assets of the surviving partnership immediately prior to the consummation of such transaction; 

the rights, preferences and privileges of the holders of interests in the surviving partnership are at least as favorable as those in effect immediately prior to the 
consummation of such transaction and as those applicable to any other limited partners or non-managing members of the surviving partnership; and 

the rights of the limited partners or non-managing members of the surviving partnership include at least one of the following: (i) the right to redeem their 
interests in the surviving partnership for the consideration available to such persons pursuant to Digital Realty Trust, L.P.’s partnership agreement; or (ii) the 
right to redeem their interests for cash on terms equivalent to those in effect with respect to their common units immediately prior to the consummation of such 
transaction (or, if the ultimate controlling person of the surviving partnership has publicly traded common equity securities, for such common equity securities, 
with an exchange ratio based on the determination of relative fair market value of such securities and the shares of Digital Realty Trust, Inc. common stock). 

These provisions may discourage others from trying to acquire control of Digital Realty Trust, Inc. and may delay, defer or prevent a change of control transaction that might be 

beneficial to Digital Realty Trust, Inc.’s stockholders and Digital Realty Trust, L.P.’s unitholders. 

The change of control conversion features of Digital Realty Trust, Inc.’s preferred stock may make it more difficult for a party to take over our company or discourage a party 

from taking over our company. 

Upon the occurrence of specified change of control transactions, holders of our series E preferred stock, series F preferred stock, series G preferred stock and series H preferred stock 
will have the right (unless, prior to the change of control conversion date, we have provided or provide notice of our election to redeem such preferred stock) to convert some or all of their 
series E preferred stock, series F preferred stock, series G preferred stock or series H preferred stock, as applicable, into shares of our common stock (or equivalent value of alternative 
consideration), subject to caps set forth in the articles supplementary governing the applicable series of preferred stock. The change of control conversion features of the series E preferred 
stock,  

23 

 
 
 
 
Table of Contents 

Index to Financial Statements 

series F preferred stock, series G preferred stock and series H preferred stock may have the effect of discouraging a third party from making an acquisition proposal for our company or of 
delaying, deferring or preventing certain change of control transactions of our company under circumstances that otherwise could provide the holders of our common stock, series E 
preferred stock, series F preferred stock, series G preferred stock and series H preferred stock with the opportunity to realize a premium over the then-current market price or that 
stockholders may otherwise believe is in their best interests. 

Digital Realty Trust, Inc. could increase or decrease the number of authorized shares of stock and issue stock without stockholder approval.  

Digital Realty Trust, Inc.’s charter authorizes the company’s board of directors, without stockholder approval, to amend the charter from time to time to increase or decrease the 
aggregate number of authorized shares of stock or the number of authorized shares of stock of any class or series, to issue authorized but unissued shares of the company’s common stock or 
preferred stock and, subject to the voting rights of holders of preferred stock, to classify or reclassify any unissued shares of the company’s common stock or preferred stock into other 
classes of series of stock and to set the preferences, rights and other terms of such classified or reclassified shares. Although Digital Realty Trust, Inc.’s board of directors has no such 
intention at the present time, it could establish an additional class or series of preferred stock that could, depending on the terms of such class or series, delay, defer or prevent a transaction 
or a change of control that might be in the best interest of Digital Realty Trust, Inc.’s stockholders and Digital Realty Trust, L.P.’s unitholders. 

Certain provisions of Maryland law could inhibit changes in control. Certain provisions of the Maryland General Corporation Law, or MGCL, may have the effect of impeding a 

third party from making a proposal to acquire Digital Realty Trust, Inc. or of impeding a change of control under circumstances that otherwise could be in the best interests of Digital Realty 
Trust, Inc.’s stockholders and Digital Realty Trust, L.P.’s unitholders, including: 

• 

• 

“business combination” provisions that, subject to limitations, prohibit certain business combinations between Digital Realty Trust, Inc. and an “interested 
stockholder” (defined generally as any person who beneficially owns, directly or indirectly, 10% or more of the voting power of the company’s outstanding shares of voting 
stock or an affiliate or associate of the company who, at any time within the two-year period prior to the date in question, was the beneficial owner, directly or indirectly, of 
10% or more of the voting power of the company’s then outstanding shares of stock) or an affiliate thereof for five years after the most recent date on which the stockholder 
becomes an interested stockholder, and thereafter imposes special appraisal rights and supermajority voting requirements on these combinations; and 

“control share” provisions that provide that “control shares” of Digital Realty Trust, Inc. (defined as shares which, when aggregated with other shares controlled by the 
stockholder (except solely by virtue of a revocable proxy), entitle the stockholder to exercise one of three increasing ranges of voting power in electing directors) acquired in a 
“control share acquisition” (defined as the direct or indirect acquisition of ownership or control of issued and outstanding “control shares”) have no voting rights except to the 
extent approved by the company’s stockholders by the affirmative vote of at least two-thirds of all the votes entitled to be cast on the matter, excluding all interested shares. 

Digital Realty Trust, Inc. has opted out of these provisions of the MGCL, in the case of the business combination provisions of the MGCL by resolution of its board of directors, and 

in the case of the control share provisions of the MGCL pursuant to a provision in its bylaws. However, Digital Realty Trust, Inc.’s board of directors may by resolution elect to opt in to the 
business combination provisions of the MGCL and the company may, by amendment to its bylaws, opt in to the control share provisions of the MGCL in the future. 

The provisions of Digital Realty Trust, Inc.’s charter on removal of directors and the advance notice provisions of Digital Realty Trust, Inc.’s bylaws could delay, defer or prevent a 

transaction or a change of control of the company that might be in the best interest of Digital Realty Trust, Inc.’s stockholders and Digital Realty Trust, L.P.’s unitholders. Likewise, if 
Digital Realty Trust, Inc.’s board of directors were to opt in to the business combination provisions of the MGCL or the provisions of Title 3, Subtitle 8 of the MGCL not currently 
applicable to the company, or if the provision in the Digital Realty Trust, Inc.’s bylaws opting out of the control share acquisition provisions of the MGCL were rescinded, these provisions 
of the MGCL could have similar anti-takeover effects.

Index to Financial Statements 

Digital Realty Trust, Inc.’s board of directors may change our investment and financing policies without stockholder approval or approval of Digital Realty Trust, L.P.’s 

other partners and we may become more highly leveraged, which may increase our risk of default under our debt obligations. 

Digital Realty Trust, Inc.’s board of directors adopted a policy limiting our indebtedness to 60% of our total enterprise value. Our total enterprise value is defined as the sum of the 
market value of Digital Realty Trust, Inc.’s outstanding common stock (which may decrease, thereby increasing our debt to total capitalization ratio), excluding options issued under our 
incentive award plan, plus the aggregate value of Digital Realty Trust, L.P. units not held by Digital Realty Trust, Inc. (with the per unit value equal to the market value of one share of 
Digital Realty Trust, Inc. common stock and excluding long-term incentive units and Class C units), plus the liquidation preference of Digital Realty Trust, Inc.’s outstanding preferred 
stock, plus the book value of our total consolidated indebtedness. However, the organizational documents of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. do not limit the amount 
or percentage of indebtedness, funded or otherwise, that we may incur. Digital Realty Trust, Inc.’s board of directors may alter or eliminate our current policy on borrowing at any time 
without stockholder or unitholder approval. If this policy changed, we could become more highly leveraged which could result in an increase in our debt service and which could materially 
adversely affect our cash flow and our ability to pay dividends to Digital Realty Trust, Inc.’s stockholders or distributions to Digital Realty Trust, L.P.’s unitholders. Higher leverage also 
increases the risk of default on our obligations. 

Digital Realty Trust, Inc.’s rights and the rights of its stockholders to take action against its directors and officers are limited. 

Maryland law provides that Digital Realty Trust, Inc.’s directors have no liability in their capacities as directors if they perform their duties in good faith, in a manner they reasonably 

believe to be in the company’s best interests and with the care that an ordinarily prudent person in a like position would use under similar circumstances. As permitted by the MGCL, 
Digital Realty Trust, Inc.’s charter limits the liability of the company’s directors and officers to the company and its stockholders for money damages, except for liability resulting from: 

• 

• 

actual receipt of an improper benefit or profit in money, property or services; or

a final judgment based upon a finding of active and deliberate dishonesty by the director or officer that was material to the cause of action adjudicated.

In addition, Digital Realty Trust, Inc.’s charter authorizes the company to obligate itself, and the company’s bylaws require it, to indemnify the company’s directors and officers for 
actions taken by them in those capacities and to pay or reimburse their reasonable expenses in advance of final disposition of a proceeding to the maximum extent permitted by Maryland 
law and Digital Realty Trust, Inc. has entered into indemnification agreements with its officers and directors. As a result, Digital Realty Trust, Inc. and its stockholders may have more 
limited rights against its directors and officers than might otherwise exist under common law. Accordingly, in the event that actions taken in good faith by any of Digital Realty Trust, Inc.’s 
directors or officers impede the performance of the company, the company’s stockholders’ ability to recover damages from that director or officer will be limited. 

Risks Related to Taxes and Digital Realty Trust, Inc.’s Status as a REIT 

Failure to qualify as a REIT would have significant adverse consequences to Digital Realty Trust, Inc. and its stockholders and to Digital Realty Trust, L.P. and its 

unitholders. 

Digital Realty Trust, Inc. has operated and intends to continue operating in a manner that it believes will allow it to qualify as a REIT for federal income tax purposes under the Code. 
Digital Realty Trust, Inc. has not requested and does not plan to request a ruling from the IRS that it qualifies as a REIT. Qualification as a REIT involves the application of highly technical 
and complex Code provisions for which there are only limited judicial and administrative interpretations. The complexity of these provisions and of the applicable Treasury Regulations that 
have been promulgated under the Code is greater in the case of a REIT that, like Digital Realty Trust, Inc., holds its assets through a partnership. The determination of various factual 
matters and circumstances not entirely within Digital Realty Trust, Inc.’s control may affect its ability to qualify as a REIT. In order to qualify as a REIT, Digital Realty Trust, Inc. must 
satisfy a number of requirements, including requirements regarding the ownership of its stock, requirements regarding the composition of its assets and a requirement that at least 95% of its 
gross income in any year must be derived from qualifying sources, such as “rents from real property.” Also, Digital Realty Trust, Inc. must make distributions to stockholders aggregating 
annually at least 90% of its net taxable income, excluding any net capital gains.

Index to Financial Statements 

If Digital Realty Trust, Inc. loses its REIT status, it will face serious tax consequences that would substantially reduce its cash available for distribution, including cash available to 

pay dividends to its stockholders, for each of the years involved because: 

• 

• 

• 

Digital Realty Trust, Inc. would not be allowed a deduction for dividends paid to stockholders in computing its taxable income and would be subject to federal income tax at 
regular corporate rates; 

Digital Realty Trust, Inc. also could be subject to the federal alternative minimum tax and possibly increased state and local taxes; and

unless Digital Realty Trust, Inc. is entitled to relief under applicable statutory provisions, it could not elect to be taxed as a REIT for four taxable years following the year 
during which it was disqualified. 

In addition, if Digital Realty Trust, Inc. fails to qualify as a REIT, it will not be required to make distributions to stockholders, and accordingly, distributions Digital Realty Trust, L.P. 

makes to its unitholders could be similarly reduced. As a result of all these factors, Digital Realty Trust, Inc.’s failure to qualify as a REIT also could impair our ability to expand our 
business and raise capital, and would materially adversely affect the value of Digital Realty Trust, Inc.’s stock and Digital Realty Trust, L.P.’s units. 

In certain circumstances, Digital Realty Trust, Inc. may be subject to federal and state taxes as a REIT, which would reduce its cash available for distribution to its 

stockholders. 

Even if Digital Realty Trust, Inc. qualifies as a REIT for federal income tax purposes, it may be subject to some federal, state and local taxes on its income or property and, in certain 

cases, a 100% penalty tax, in the event it sells property as a dealer. In addition, our domestic corporate subsidiary, Digital Services, Inc., which is a taxable REIT subsidiary of Digital 
Realty Trust, Inc., could be subject to federal and state taxes, and our foreign properties and companies are subject to tax in the jurisdictions in which they operate and are located. Any 
federal, state or other taxes Digital Realty Trust, Inc. pays will reduce its cash available for distribution to stockholders. 

To maintain Digital Realty Trust, Inc.’s REIT status, we may be forced to borrow funds during unfavorable market conditions. 

To qualify as a REIT, Digital Realty Trust, Inc. generally must distribute to its stockholders at least 90% of its net taxable income each year, excluding capital gains, and Digital 
Realty Trust, Inc. will be subject to regular corporate income taxes to the extent that it distributes less than 100% of its net taxable income each year. In addition, Digital Realty Trust, Inc. 
will be subject to a 4% nondeductible excise tax on the amount, if any, by which distributions paid by Digital Realty Trust, Inc. in any calendar year are less than the sum of 85% of its 
ordinary income, 95% of its capital gain net income and 100% of its undistributed income from prior years. While historically Digital Realty Trust, Inc. has satisfied these distribution 
requirements by making cash distributions to its stockholders, a REIT is permitted to satisfy these requirements by making distributions of cash or other property. We may need to borrow 
funds for Digital Realty Trust, Inc. to meet the REIT distribution requirements even if the then prevailing market conditions are not favorable for these borrowings. These borrowing needs 
could result from differences in timing between the actual receipt of cash and inclusion of income for federal income tax purposes, or the effect of non-deductible capital expenditures, the 
creation of reserves or required debt or amortization payments. 

Dividends payable by REITs do not qualify for the reduced tax rates available for some dividends. 

Income from “qualified dividends” payable to U.S. stockholders that are individuals, trusts and estates are generally subject to tax at preferential rates. Dividends payable by REITs, 

however, generally are not eligible for the preferential tax rates applicable to qualified dividend income. Although these rules do not adversely affect the taxation of REITs or dividends 
payable by REITs, to the extent that the preferential rates continue to apply to regular corporate qualified dividends, investors who are individuals, trusts and estates may perceive 
investments in REITs to be relatively less attractive than investments in the stocks of non-REIT corporations that pay dividends, which could materially and adversely affect the value of the 
shares of REITs, including the per share trading price of Digital Realty Trust, Inc.’s capital stock. 

The tax imposed on REITs engaging in “prohibited transactions” may limit our ability to engage in transactions which would be treated as sales for federal income tax 

purposes. 

A REIT’s net income from prohibited transactions is subject to a 100% penalty tax. In general, prohibited transactions are sales or other dispositions of property, other than 

foreclosure property, held primarily for sale to customers in the ordinary course of business. Although we do not intend to hold any properties that would be characterized as held for sale to 
customers in the ordinary course of our business, unless a sale or disposition qualifies under certain statutory safe harbors, such  

26 

 
 
 
Table of Contents 

Index to Financial Statements 

characterization is a factual determination and no guarantee can be given that the IRS would agree with our characterization of our properties or that we will always be able to make use of 
the available safe harbors. 

Complying with REIT requirements may cause us to forego otherwise attractive opportunities or liquidate otherwise attractive investments. 

To qualify as a REIT for federal income tax purposes, Digital Realty Trust, Inc. must continually satisfy tests concerning, among other things, its sources of income, the nature and 
diversification of its assets (including its proportionate share of Digital Realty Trust, L.P.’s assets), the amounts it distributes to its stockholders and the ownership of its capital stock. If 
Digital Realty Trust, Inc. fails to comply with one or more of the asset tests at the end of any calendar quarter, it must correct the failure within 30 days after the end of the calendar quarter 
or qualify for certain statutory relief provisions to avoid losing its REIT qualification and suffering adverse tax consequences. In order to meet these tests, we may be required to forego 
investments we might otherwise make or to liquidate otherwise attractive investments. Thus, compliance with the REIT requirements may hinder our performance and reduce amounts 
available for distribution to Digital Realty Trust, Inc.’s stockholders and Digital Realty Trust, L.P.’s unitholders. 

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

The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Department of the Treasury. 

Changes to the tax laws, with or without retroactive application, could materially and adversely affect Digital Realty Trust, Inc.’s stockholders, Digital Realty Trust, L.P.’s unitholders 
and/or us. We cannot predict how changes in the tax laws might affect our investors and/or us. New legislation, Treasury Regulations, administrative interpretations or court decisions could 
significantly and negatively affect Digital Realty Trust, Inc.’s ability to qualify as a REIT or the federal income tax consequences of such qualification. 

The power of Digital Realty Trust, Inc.’s board of directors to revoke Digital Realty Trust, Inc.’s REIT election without stockholder approval may cause adverse 

consequences to Digital Realty Trust, Inc.’s stockholders and Digital Realty Trust, L.P.’s unitholders. 

Digital Realty Trust, Inc.’s charter provides that its board of directors may revoke or otherwise terminate its REIT election, without the approval of its stockholders, if it determines 

that it is no longer in Digital Realty Trust, Inc.’s best interests to continue to qualify as a REIT. If Digital Realty Trust, Inc. ceases to qualify as a REIT, it would become subject to U.S. 
federal income tax on its taxable income and it would no longer be required to distribute most of its taxable income to its stockholders and accordingly, distributions Digital Realty Trust, 
L.P. makes to its unitholders could be similarly reduced. 

Forward-Looking Statements 

We make statements in this report that are forward-looking statements within the meaning of the federal securities laws. In particular, statements pertaining to our capital resources, 
portfolio performance including our ability to lease vacant space and space under development, leverage policy and acquisition and capital expenditure plans, as well as our discussion of 
“Factors Which May Influence Future Results of Operations,” contain forward-looking statements. Likewise, all of our statements regarding anticipated market conditions, demographics 
and results of operations are forward-looking statements. You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” 
“will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “pro forma,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases which are 
predictions of or indicate future events or trends and which do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or 
intentions. 

Forward-looking statements involve numerous risks and uncertainties and you should not rely on them as predictions of future events. Forward-looking statements depend on 
assumptions, data or methods which may be incorrect or imprecise and we may not be able to realize them. We do not guarantee that the transactions and events described will happen as 
described or that they will happen at all. The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the 
forward-looking statements: 

• 

• 

• 

• 

the impact of current global economic, credit and market conditions;

current local economic conditions in our geographic markets;

decreases in information technology spending, including as a result of economic slowdowns or recession;

adverse economic or real estate developments in our industry or the industry sectors that we sell to (including risks relating to decreasing real estate valuations and impairment 
charges);

The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance, including factors and risks included in other sections 
of this report, including under Part I, Item 1A, Risk Factors. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and 
it is not possible for management to predict all such risk factors, nor can we assess the impact of all such risk factors on the business or the extent to which any factor, or combination of 
factors, may cause actual results to differ materially from those contained in any forward-looking statements. While forward-looking statements reflect our good faith beliefs, they are not 
guaranties of future performance. We disclaim any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, new 
information, data or methods, future events or other changes.

Net rentable square feet at a building represents the current square feet at that building under lease as specified in the lease agreements plus management’s estimate of space 
available for lease. We estimate the total net rentable square feet available for lease based on a number of factors in addition to contractually leased square feet, including available 
power, required support space and common area. Net rentable square feet includes tenants’ proportional share of common areas but excludes space held for development. 
Space under active development includes current base building and data center projects in progress.
Space held for future development includes space held for future data center development, and excludes space under active development.
Annualized rent represents the monthly contractual rent (defined as cash base rent before abatements) under existing leases as of December 31, 2014 multiplied by 12.
Excludes space held for future development and space under active development. We estimate the total square feet available for lease based on a number of factors in addition to 
contractually leased square feet, including available power, required support space and common area. 
Annualized rent per square foot represents annualized rent as computed above, divided by the total square footage under lease as of the same date.

Digital Realty Trust, Inc. intends to continue to declare quarterly dividends on its common stock. The actual amount, form and timing of dividends, however, will be at the discretion 
of the board of directors and will depend upon Digital Realty Trust, Inc.’s financial condition in addition to the requirements for qualification as a REIT under the Code, and no assurance 
can be given as to the amounts, form or timing of future dividends. Our global revolving credit facility, our Prudential shelf facility and our term loan facility prohibit us from making 
distributions to our stockholders, or redeeming or otherwise repurchasing shares of our capital stock, including our common stock, after the occurrence and during the continuance of an 
event of default, except in limited circumstances including as necessary to enable us to maintain our qualification as a REIT and to avoid the payment of income or excise tax. 
Consequently, after the occurrence and during the continuance of an event of default under our global revolving credit facility, Prudential shelf facility or term loan facility, we may not be 
able to pay all or a portion of the dividends payable to the holders of our common stock. 

Subject to the distribution requirements applicable to REITs under the Code, Digital Realty Trust, Inc. intends, to the extent practicable, to invest substantially all of the proceeds from
sales and refinancings of its assets in real estate-related assets and other assets. Digital Realty Trust, Inc. may, however, under certain circumstances, make a dividend of capital or of assets. 
Such dividends, if any, will be made at the discretion of the board of directors. 

As of February 17, 2015, there were approximately 171 holders of record of Digital Realty Trust, Inc.’s common stock. This figure does not reflect the beneficial ownership of shares 

held in nominee name.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

The following discussion should be read in conjunction with the consolidated financial statements and notes thereto appearing elsewhere in this report. We make statements in this 

section that are forward-looking statements within the meaning of the federal securities laws. For a complete discussion of forward-looking statements, see the section in this report entitled 
“Forward-Looking Statements.” Certain risk factors may cause our actual results, performance or achievements to differ materially from those expressed or implied by the following 
discussion. For a discussion of such risk factors, see the sections in this report entitled “Risk Factors” and “Forward-Looking Statements.” 

Occupancy percentages included in the following discussion, for some of our properties, are calculated based on factors in addition to contractually leased square feet, including 

available power, required support space and common area. 

Overview 

Our company. Digital Realty Trust, Inc. completed its initial public offering of common stock, or our IPO, on November 3, 2004. We believe that we have operated in a manner that 
has enabled us to qualify, and have elected to be treated, as a REIT under Sections 856 through 860 of the Code. Our company was formed on March 9, 2004. During the period from our 
formation until we commenced operations in connection with the completion of our IPO, we did not have any corporate activity other than the issuance of shares of Digital Realty Trust, 
Inc. common stock in connection with the initial capitalization of the company. Our operating partnership was formed on July 21, 2004. 

Business and strategy. Our primary business objectives are to maximize: (i) sustainable long-term growth in earnings and funds from operations per share and unit, (ii) cash flow and 

returns to our stockholders and our operating partnership’s unitholders through the payment of distributions and (iii) return on invested capital. We expect to achieve our objectives by 
focusing on our core business of investing in and developing technology-related real estate. A significant component of our current and future internal growth is anticipated through the 
development of our existing space held for development and acquisition of new properties. We target high quality, strategically located properties containing applications and operations 
critical to the day-to-day operations of corporate enterprise datacenter and technology industry tenants and properties that may be developed for such use. Most of our properties contain 
fully redundant electrical supply systems, multiple power feeds, above-standard cooling systems, raised floor areas, extensive in-building communications cabling and high-level security 
systems. We focus solely on technology-related real estate because we believe that the growth in corporate datacenter adoption and the technology-related real estate industry generally will 
continue to be superior to that of the overall economy. 

As of December 31, 2014, we owned an aggregate of 131 properties, including 14 properties held as investments in unconsolidated joint ventures, with approximately 24.6 million 

rentable square feet including approximately 1.3 million square feet of space under active development and approximately 1.2 million square feet of space held for future development. The 
14 properties held as investments in unconsolidated joint ventures have an aggregate of approximately 1.9 million rentable square feet. The 14 parcels of developable land we own 
comprised approximately 178 acres. At December 31, 2014, approximately 1.3 million square feet was under construction for Turn-Key Flex®, Powered Base Building® and Custom 
Solutions products, all of which are expected to be income producing on or after completion, in six U.S. domestic markets, one European market, one Canadian market, one Australian 
market and our Singapore market, consisting of approximately 0.7 million square feet of base building construction and 0.6 million square feet of data center construction. 

We have developed detailed, standardized procedures for evaluating new real estate investments to ensure that they meet our financial, technical and other criteria. We expect to 
continue to acquire additional assets as a part of our growth strategy. We intend to aggressively manage and lease our assets to increase their cash flow. We may continue to build out our 
development portfolio when justified by anticipated returns. 

We may acquire properties subject to existing mortgage financing and other indebtedness or we may incur new indebtedness in connection with acquiring or refinancing these 

properties. Debt service on such indebtedness will have a priority over any cash dividends with respect to Digital Realty Trust, Inc.’s common stock and preferred stock. We currently 
intend to limit our indebtedness to 60% of our total enterprise value and, based on the closing price of Digital Realty Trust, Inc. common stock on December 31, 2014 of $66.30, our ratio of 
debt to total enterprise value was approximately 31%. Our total enterprise value is defined as the sum of the market value of Digital Realty Trust, Inc.’s outstanding common stock (which 
may decrease, thereby increasing our debt to total enterprise value ratio), excluding options issued under our company’s incentive award plan, plus the liquidation value of Digital Realty 
Trust, Inc.’s preferred stock, plus the aggregate value of our operating partnership’s units not held by Digital Realty Trust, Inc. (with the per unit value equal to the market value of one 
share of  

48 

 
 
 
 
Table of Contents 

Index to Financial Statements 

Digital Realty Trust, Inc. common stock and excluding long-term incentive units, Class C units and Class D units), plus the book value of our total consolidated indebtedness. 

Revenue base. As of December 31, 2014, we owned 131 properties through our operating partnership, including 14 properties held as investments in unconsolidated joint ventures and 

developable land. These properties are mainly located throughout the U.S., with 21 properties located in Europe, three properties in Australia, two properties in Canada and two properties 
in Asia. We, through our predecessor, acquired our first portfolio property in January 2002 and have added properties through acquisition and development activities as follows:

33 Chun Choi Street (Hong Kong); and two unconsolidated non-managed joint ventures: 2001 Sixth Avenue (Seattle) and 2020 Fifth Avenue (Seattle). 
Current net rentable square feet as of December 31, 2014, which represents the current square feet under lease as specified in the applicable lease agreements plus management’s 
estimate of space available for lease based on engineering drawings. Includes tenants’ proportional share of common areas but excludes space held for development.

Includes four developed buildings (43940 Digital Loudoun Plaza in Northern Virginia, 3825 NW Aloclek Place in Portland, Oregon, 98 Radnor Drive in Melbourne, Australia and 
1-23 Templar Road in Sydney, Australia) placed into service in 2012 and 2013 that were acquired in 2011. 
43790 Devin Shafron Drive and 21551 Beaumeade Circle, which were previously included as part of the Devin Shafron buildings and Beaumeade Circle Portfolio, respectively, 
are now each separately included in the property count because they were separately contributed to an unconsolidated joint venture in September 2013. 
43915 Devin Shafron Drive, which was previously included as part of the Devin Shafron buildings, is now separately included in the property count because it was separately 
contributed to an unconsolidated joint venture in September 2014. 

As of December 31, 2014, the properties in our portfolio, including the 14 properties held as investments in unconsolidated joint ventures, were approximately 93.2% leased excluding 

approximately 1.3 million square feet of space under active development and approximately 1.2 million square feet of space held for future development. Due to the capital-intensive and 
long-term nature of the operations being supported, our lease terms are generally longer than standard commercial leases. As of December 31, 2014, our average lease term at signing is 
approximately 12 years, with an average of approximately six years remaining. Our scheduled lease expirations through December 31, 2016 are 14.7% of rentable square feet excluding 
month-to-month leases, space under active development and space held for future development as of December 31, 2014. 

On September 27, 2013, we formed a joint venture with an investment fund managed by Prudential Real Estate Investors (PREI®). We contributed nine Powered Base Building® data 

centers totaling 1.06 million square feet and valued at approximately $366.4 million (excluding $2.8 million of closing costs). The PREI®-managed fund took an 80% interest in the joint 
venture and we retained a 20% interest. The joint venture is structured to provide a current annual preferred return from cash flow first to the PREI®-managed interest, then to our interest, 
after which a portion of any excess cash flows is shared by the partners based on their respective interests and the remaining portion is paid to us as a promote interest. We perform the day-
to-day accounting and property management functions for the joint venture and, as such, we earn a management fee for the services provided. Although we are the managing member of the 
joint venture and manage the day-to-day activities, all significant decisions, including approval of annual budgets and setting the amount of our management fees require approval of the 
PREI® member. Thus we concluded we do not own a controlling interest and will account for our interest in the joint venture as an equity method investment, which will result in a 
reduction in same-store revenues and net income from these properties on our income statement relative to historical periods.  

On March 5, 2014, we contributed the 636 Pierce Street property, which we acquired in December 2013, to our unconsolidated joint venture with PREI®. The property was valued at 
approximately $40.4 million and subject to $26.1 million in debt, which the joint venture assumed. The PREI® fund contributed approximately $11.4 million in cash for their 80% share of 
the net asset value of $14.3 million. Subsequent to the closing, the joint venture refinanced its existing debt with $23.0 million drawn from the joint venture’s bank facility. Including the 
refinancing costs, the PREI® fund contributed $17.5 million for the 636 Pierce Street property, bringing its contributed capital in the joint venture to $164.8 million.  

On April 7, 2014, the operating partnership sold 6 Braham Street to the tenant pursuant to a sale of the ownership interests in the operating partnership’s wholly owned subsidiary that 
owned the building for £25.0 million (or approximately $41.5 million based on the exchange rate as of April 7, 2014). The transaction after costs and various tenant prepayments resulted in 
net proceeds of approximately £22.6 million (or approximately $37.5 million based on the exchange rate as of April 7, 2014) and a net gain of approximately $15.9 million.  

On September 9, 2014, we formed a joint venture with an affiliate of Griffin Capital Essential Asset REIT, Inc. (GCEAR). We contributed to the joint venture the property located at 

43915 Devin Shafron Drive (Building A) in Ashburn, Virginia, which is a Turn-Key Flex® data center property valued at approximately $185.5 million (excluding approximately $2.1 
million of closing costs). GCEAR contributed cash to the joint venture and will hold an 80% interest in the joint venture. We retained a 20% interest in the joint venture. The joint venture 
arranged a $102.0 million five-year secured bank loan at LIBOR plus 225 basis points, representing a loan-to-value ratio of approximately 55%. The joint venture entered into an interest 
rate swap agreement to effectively fix the interest rate on approximately $51.0 million of borrowings under the loan through September 2019. Two one-year extensions of the maturity date 
are available under the loan agreement, which the joint venture may exercise if certain conditions are met. Proceeds from this loan offset the initial cash capital contribution amount 
required from GCEAR and was used to provide us with a special distribution on account of a portion of the contribution value of the property. The transaction generated approximately 
$167.5 million of net proceeds to us, comprised of our share of the initial draw-down on the bank loan in addition to GCEAR’s equity contribution, less our share of closing costs. 
Accordingly we recognized a gain of approximately $93.5 million on the sale of the 80% interest in the joint venture during the three months ended September 30, 2014.

Factors Which May Influence Future Results of Operations 

Global market and economic conditions 

United States and international market and economic conditions in recent years have been unprecedented and challenging with tighter credit conditions and slower economic growth 

in many markets in which we own properties and conduct our operations. The U.S. and global economies have experienced a recession and face continued concerns about the systemic 
impact of adverse economic conditions, such as high energy costs, geopolitical issues, the availability and cost of credit, unstable global financial and mortgage markets, high corporate, 
consumer and governmental debt levels, ongoing sovereign debt and economic issues in European countries, and high unemployment. The European debt crisis has raised concerns 
regarding the debt burden of certain countries using the euro as their currency and their ability to meet future financial obligations. While recent economic trends across the eurozone have 
been largely positive, concerns remain regarding the creditworthiness of certain European countries which could lead to the re-introduction of individual currencies in one or more 
Eurozone countries. These potential developments, or market perceptions concerning these and related issues, could adversely affect our leasing and financing activities, rents we receive, 
potential acquisitions and development projects in Europe. 

As a result of these conditions, general economic conditions and the cost and availability of capital have been and may again be adversely affected in some or all of the markets in 
which we own properties and conduct our operations. Renewed or increased turbulence in the U.S., European, Asia Pacific and other international financial markets and economies may 
adversely affect our ability, and the ability of our tenants, to replace or renew maturing liabilities on a timely basis, access the capital markets to meet liquidity and capital expenditure 
requirements and may result in adverse effects on our, and our tenants’, financial condition and results of operations.  

In addition, our access to funds under our global revolving credit facility depends on the ability of the lenders that are parties to such facilities to meet their funding commitments to 

us. We cannot assure you that long-term disruptions in the global economy and the return of tighter credit conditions among, and potential failures or nationalizations of, third party 
financial institutions as a result of such disruptions will not have an adverse effect on our lenders. If our lenders are not able to meet their funding commitments to us, our business, results 
of operations, cash flows and financial condition could be adversely affected.  

If we do not have sufficient cash flow to continue operating our business and are unable to borrow additional funds, access our existing lines of credit or raise equity or debt capital, 

we may need to source alternative ways to increase our liquidity. Such alternatives may include, without limitation, curtailing development activity, disposing of one or more of our 
properties possibly on disadvantageous terms or entering into or renewing leases on less favorable terms than we otherwise would. 

Foreign currency exchange risk. For the years ended December 31, 2014 and 2013, we had foreign operations in the United Kingdom, Ireland, France, The Netherlands, Switzerland, 
Canada, Singapore, Australia, Japan and Hong Kong, and, as such, are subject to risk from the effects of exchange rate movements of foreign currencies, which may affect future costs and 
cash flows. Our foreign operations are conducted in the British pound sterling, Euro, Swiss franc, Australian dollar, Singapore dollar, Canadian dollar, Hong Kong dollar and the Japanese 
yen. Our primary currency exposures are to the British pound sterling, Euro and the Singapore dollar. We attempt to mitigate a portion of the risk of currency fluctuation by financing our 
investments in the local currency denominations, although there can be no assurance that this will be effective. As a result, changes in the relation of any such foreign currency to U.S. 
dollars may affect our revenues, operating margins and distributions and may also affect the book value of our assets and the amount of stockholders’ equity. 

Rental income. The amount of rental income generated by the properties in our portfolio depends on several factors, including our ability to maintain or improve the occupancy rates 

of currently leased space and to lease currently available space and space available from lease terminations. Excluding approximately 1.3 million square feet of space under active 
development and approximately 1.2 million square feet of space held for future development as of December 31, 2014, the occupancy rate of the properties in our portfolio, including the 14 
properties held as investments in unconsolidated joint ventures, was approximately 93.2% of our net rentable square feet. 

As of December 31, 2014, we had over 650 tenants in our portfolio, including the 14 properties held in our managed portfolio of unconsolidated joint ventures. As of December 31, 

2014, approximately 91% of our leases (on a rentable square footage basis) contained base rent escalations that were either fixed (generally ranging from 2% to 4%) or indexed based on a 
consumer price index or other similar inflation related index. We cannot assure you that these escalations will cover any increases in our costs or will otherwise keep rental rates at or above 
market rates. 

The amount of rental income generated by us also depends on maintaining or increasing rental rates at our properties, which in turn depends on several factors, including supply and 

demand and market rates for data center space. Included in our approximately 20.3 million net rentable square feet, excluding space under active development and space held for future  

51

development and 14 properties held as investments in unconsolidated joint ventures, at December 31, 2014 is approximately 0.6 million square feet of datacenter space with extensive 
installed tenant improvements available for lease. Since our IPO, we have leased approximately 4.0 million square feet of similar space, including Turn-Key Flex® space. Our Turn-Key 
Flex® product is an effective solution for tenants who prefer to utilize a partner with the expertise or capital budget to provide extensive datacenter infrastructure and security. Our expertise 
in datacenter construction and operations enables us to lease space to these tenants at a premium over other uses. In addition, as of December 31, 2014, we had approximately 1.3 million 
square feet of space under active development and approximately 1.2 million square feet of space held for future development, or approximately 10% of the total rentable space in our 
portfolio, including one vacant property comprising approximately 0.1 million square feet and the 14 properties held as investments in unconsolidated joint ventures. Our ability to grow 
earnings depends in part on our ability to develop space and lease development space at favorable rates, which we may not be able to obtain. Development space requires significant capital 
investment in order to develop datacenter facilities that are ready for use and, in addition, we may require additional time or encounter delays in securing tenants for development space. We 
may purchase additional vacant properties and properties with vacant development space in the future. We will require additional capital to finance our development activities, which may 
not be available or may not be available on terms acceptable to us, including as a result of the conditions described above under “Global market and economic conditions.” 

In addition, the timing between when we sign a new lease with a tenant and when that lease commences and we begin to generate rental income may be significant and may not be 

easily predictable. Certain leases may provide for staggered commencement dates for additional space, the timing of which may be delayed significantly.  

Economic downturns, including as a result of the conditions described above under “Global market and economic conditions,” or regional downturns affecting our markets or 

downturns in the technology-related real estate industry that impair our ability to lease or renew or re-lease space, or otherwise reduce returns on our investments or the ability of our 
tenants to fulfill their lease commitments, as in the case of tenant bankruptcies, could adversely affect our ability to maintain or increase rental rates at our properties. 

52

Scheduled lease expirations. Our ability to re-lease expiring space at rental rates equal to or in excess of current rental rates will impact our results of operations. In addition to 
approximately 1.5 million square feet of available space in our portfolio, which excludes approximately 1.3 million square feet of space under active development and approximately 1.2 
million square feet of space held for future development as of December 31, 2014 and the two properties held as investments in our non-managed unconsolidated joint ventures, leases 
representing approximately 8.0% and 6.7% of the net rentable square footage of our portfolio are scheduled to expire during the years ending December 31, 2015 and 2016, respectively. 

During the year ended December 31, 2014, we signed new leases totaling approximately 1.4 million square feet of space and renewal leases totaling approximately 1.3 million square 

feet of space. The following table summarizes our leasing activity in the year ended December 31, 2014:

For some of our properties, we calculate square footage based on factors in addition to contractually leased square feet, including power, required support space and common area.

Rental rates represent annual estimated cash rent per rentable square foot adjusted for straight-line rents in accordance with GAAP. GAAP rental rates are inclusive of tenant 
concessions, if any. 

Excludes short term leases.

Commencement dates for the leases signed range from 2014 to 2017.

Includes leases signed for new and re-leased space.

Our ability to re-lease or renew expiring space at rental rates equal to or in excess of current rental rates will impact our results of operations. We continue to see strong demand in 

most of our key markets for datacenter space and, subject to the supply of available datacenter space in these markets, expect the rental rates we are likely to achieve on any new, re-leased 
or renewed datacenter space leases for 2015 expirations on an average aggregate basis will generally be higher than the rates currently being paid for the same space on a GAAP basis and 
flat on a cash basis. For the year ended December 31, 2014, rents on renewed space increased by an average of 6.3% on a GAAP basis on our Turn-Key Flex® space compared to the 
expiring rents and increased by an average of 26.5% on a GAAP basis on our Powered Base Building® space compared to the expiring rents. Our past performance may not be indicative of 
future results, and we cannot assure you that leases will be renewed or that our properties will be re-leased at all or at rental rates equal to or above the current average rental rates. Further,

renewed rental rates in a particular market may not be consistent with rental rates across our portfolio as a whole and may fluctuate from one period to another due to a number of factors, 
including local real estate conditions, local supply and demand for datacenter space, competition from other datacenter developers or operators, the condition of the property and whether 
the property, or space within the property, has been developed. 

Market concentration. We depend on the market for technology-based real estate in specific geographic regions and significant changes in these regional markets can impact our 

future results. As of December 31, 2014, our portfolio, including the 14 properties held as investments in unconsolidated joint ventures, was geographically concentrated in the following 
metropolitan markets:

Annualized rent is monthly contractual rent (defined as cash base rent before abatements) under existing leases as of December 31, 2014 multiplied by 12. The aggregate amount 
of abatements for the year ended December 31, 2014 was approximately $31.1 million. 

Operating expenses. Our operating expenses generally consist of utilities, property and ad valorem taxes, property management fees, insurance and site maintenance costs, as well as 
rental expenses on our ground and building leases. In particular, our buildings require significant power to support the datacenter operations contained in them. Many of our leases contain 
provisions under which the tenants reimburse us for a portion of property operating expenses and real estate taxes incurred by us. However, we generally are not entitled to reimbursement 
of property operating expenses, other than utility expense, and real estate taxes under our leases for Turn-Key Flex® facilities. We also incur general and administrative expenses, including 
expenses relating to our asset management function, as well as significant legal, accounting and other expenses related to corporate governance, SEC reporting and compliance with the 
various provisions of the Sarbanes-Oxley Act. Increases or decreases in such operating expenses will impact our overall performance. We expect to incur additional operating expenses as 
we continue to expand. 

Climate change legislation. In June 2009, the U.S. House of Representatives approved comprehensive clean energy and climate change legislation intended to cut greenhouse gas, or 

GHG, emissions, create new clean energy jobs and enhance the energy independence of the United States, which included a cap-and-trade program for GHG emissions. The U.S. Senate did 
not subsequently pass similar legislation. New climate change legislation was introduced in the U.S. Senate in 2013, but significant opposition to federal climate change legislation exists. 
As a result, near-term action to reduce GHG emissions likely will be focused on regulatory agencies, primarily the U.S. Environmental Protection Agency, or EPA, and state actions. The 
EPA has been moving aggressively to regulate GHG emissions from automobiles and large stationary sources, including electricity producers, using its own authority under the Clean Air 
Act. The EPA made an endangerment finding in 2009 that  

54 

 
 
 
  
 
Table of Contents

allows it to create regulations imposing emission reporting, permitting, control technology installation, and monitoring requirements applicable to certain emitters of GHGs, including 
facilities that provide electricity to our data centers, although the materiality of the impacts will not be known until all regulations are finalized.  

The EPA has already finalized its GHG “reporting rule,” which requires that certain emitters, including electricity generators, monitor and report GHG emissions. The EPA has also 

finalized rules imposing permitting and control technology requirements upon certain newly-constructed or modified facilities which emit GHGs under the Clean Air Act New Source 
Review Prevention of Significant Deterioration, or NSR PSD, and Title V permitting programs. As a result, newly-issued NSR PSD or Title V permits for new or modified electricity 
generating and other facilities may need to address GHG emissions, including by requiring the installation of Best Available Control Technology. In addition, the EPA proposed in April 
2012 a rule that would set a GHG emission standard applicable to new electricity generating units, and the EPA re-proposed the rule in September 2013. In June 2014, the EPA released a 
proposal to regulate carbon dioxide emissions from existing power plants and set mandatory CO2 reduction targets for each state, an effort designed to achieve a thirty percent CO2 
emission reduction over 2005 levels by 2030. EPA announced in January 2015 that it plans to issue in summer 2015 final rules regulating carbon dioxide emissions from new and existing 
power plants. At the state level, California implemented a GHG cap-and-trade program that began imposing compliance obligations on industrial sectors, including electricity generators 
and importers, in January 2013. In addition, since 2005 the European Union (including the United Kingdom) has been operating under a cap-and-trade program, which directly affects the 
largest emitters of GHGs, including electricity producers from whom we purchase power. 

The cost of electric power comprises a significant component of our operating expenses. Any additional taxation or regulation of energy use, including as a result of (i) new legislation 
that Congress may pass, (ii) the regulations that the EPA has proposed or finalized, (iii) regulations under legislation that states have passed or may pass, or (iv) any further reductions in the 
EU program could significantly increase our costs, and we may not be able to effectively pass all of these costs on to our tenants. These matters could adversely impact our business, results 
of operations, or financial condition. 

Interest rates. As of December 31, 2014, we had approximately $553.9 million of variable rate debt subject to interest rate swap agreements on certain tranches of our unsecured term 

loan, along with $526.0 million and $422.7 million of variable rate debt that was outstanding on the global revolving credit facility and the unswapped portion of the unsecured term loan, 
respectively. The availability of debt and equity capital may decrease as a result of the circumstances described above under “Global market and economic conditions.” The effects on 
commercial real estate mortgages, if available, include, but may not be limited to: higher loan spreads, tightened loan covenants, reduced loan to value ratios resulting in lower borrower 
proceeds and higher principal payments. Potential future increases in interest rates and credit spreads may increase our interest expense and fixed charges and negatively affect our financial 
condition and results of operations, potentially impacting our future access to the debt and equity capital markets. Increased interest rates may also increase the risk that the counterparties to 
our swap agreements will default on their obligations, which could further increase our interest expense. If we cannot obtain capital from third party sources, we may not be able to acquire 
or develop properties when strategic opportunities exist, satisfy our debt service obligations or pay the cash dividends to Digital Realty Trust, Inc.’s stockholders necessary to maintain its 
qualification as a REIT. 

Demand for datacenter space. Our portfolio of properties consists primarily of technology-related real estate and datacenter real estate in particular. A decrease in the demand for, or 
increase in supply of, datacenter space, Internet gateway facilities or other technology-related real estate would have a greater adverse effect on our business and financial condition than if 
we owned a portfolio with a more diversified tenant base or less specialized use. We have invested in building out additional inventory primarily in what we anticipate will be our active 
major markets prior to having executed leases with respect to this space. We believe that demand continues to exceed supply in most markets in which we operate, particularly in Dallas, 
Northern Virginia and Dublin; whereas we anticipate that our Silicon Valley market may be at risk of significant over-supply. However, until this inventory is leased up, which will depend 
on a number of factors, including available datacenter space in these markets, our return on invested capital is negatively impacted. Our development activities make us particularly 
susceptible to general economic slowdowns, including recessions and the other circumstances described above under “Global market and economic conditions,” as well as adverse 
developments in the corporate datacenter, Internet and data communications and broader technology industries. Any such slowdown or adverse development could lead to reduced 
corporate IT spending or reduced demand for datacenter space. Reduced demand could also result from business relocations, including to markets that we do not currently serve. Changes in 
industry practice or in technology, such as virtualization technology, more efficient computing or networking devices, or devices that require higher power densities than today’s devices, 
could also reduce demand for the physical datacenter space we provide or make the tenant improvements in our facilities obsolete or in need of significant upgrades to remain viable. In 
addition, the development of new technologies, the adoption of new industry standards or other factors could render many of our tenants’ current products and services obsolete or 
unmarketable and contribute to a downturn in their businesses, thereby increasing the likelihood that they default under their  

55 

 
 
 
Table of Contents 

Index to Financial Statements 

leases, become insolvent or file for bankruptcy. In addition, demand for datacenter space in our properties, or the rates at which we lease space, may be adversely impacted either across our 
portfolio or in specific markets as a result of an increase in the number of competitors, or the amount of space being offered in our markets and other markets by our competitors. 

Critical Accounting Policies 

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with 

U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that affect 
the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses in the reporting period. Our actual results may differ 
from these estimates. We have provided a summary of our significant accounting policies in note 2 to our consolidated financial statements included elsewhere in this report. We describe 
below those accounting policies that require material subjective or complex judgments and that have the most significant impact on our financial condition and consolidated results of 
operations. Our management evaluates these estimates on an ongoing basis, based upon information currently available and on various assumptions management believes are reasonable as 
of the date on the front cover of this report. 

Investments in Real Estate 

Acquisition of real estate. The price that we pay to acquire a property is impacted by many factors including the condition of the property and improvements, the occupancy of the 
building, the term and rate of in-place leases, the creditworthiness of the tenants, favorable or unfavorable financing, above or below-market ground leases and numerous other factors.  

Accordingly, we are required to make subjective assessments to allocate the purchase price paid to acquire investments in real estate among the identifiable assets including 

intangibles and liabilities assumed based on our estimate of the fair value of such assets and liabilities. This includes determining the value of the property and improvements, land, ground 
leases, if any, and tenant improvements. Additionally, we evaluate the value of in-place leases on occupancy and market rent, the value of the tenant relationships, the value (or negative 
value) of above (or below) market leases, any debt or deferred taxes assumed from the seller or loans made by the seller to us and any building leases assumed from the seller. Each of these 
estimates requires a great deal of judgment and some of the estimates involve complex calculations. These allocation assessments have a direct impact on our results of operations. For 
example, if we were to allocate more value to land, there would be no depreciation with respect to such amount. If we were to allocate more value to the property as opposed to allocating to 
the value of in-place tenant leases, this amount would be recognized as an expense over a much longer period of time. This potential effect occurs because the amounts allocated to property 
are depreciated over the estimated lives of the property whereas amounts allocated to in-place tenant leases are amortized over the estimated term (including renewal and extension 
assumptions) of the leases. Additionally, the amortization of the value (or negative value) assigned to above (or below) market rate leases is recorded as an adjustment to rental revenue as 
compared to amortization of the value of in-place tenant leases and tenant relationships, which is included in depreciation and amortization in our condensed consolidated income 
statements.  

From time to time, we will receive offers for sale of our properties, either solicited or unsolicited. For those offers that are accepted, the prospective buyer will usually require a due 

diligence period before consummation of the transaction. It is not unusual for matters to arise that result in the withdrawal or rejection of the offer during this process. We classify real 
estate as “held for sale” when all criteria under the GAAP guidance has been met. 

Capitalization of Costs. Direct and indirect project costs that are clearly associated with the development of properties are capitalized as incurred. Project costs include all costs 

directly associated with the development of a property, including construction costs, interest, property taxes, insurance, legal fees and costs of personnel working on the project. Indirect 
costs that do not clearly relate to the projects under development are not capitalized and are charged to expense as incurred. 

Capitalization of costs begins when the activities necessary to get the development project ready for its intended use begin, which include costs incurred before the beginning of 
construction. Capitalization of costs ceases when the development project is substantially complete and ready for its intended use. Determining when a development project commences, 
and when it is substantially complete and ready for its intended use involves a degree of judgment. We generally consider a development project to be substantially complete and ready for 
its intended use upon receipt of a certificate of occupancy. If and when development of a property is suspended pursuant to a formal change in the planned use of the property, we will 
evaluate whether the accumulated costs exceed the estimated value of the project and write off the amount of any such excess accumulated costs. For a development project that is 
suspended for reasons other than a formal change in the planned use of such property, the accumulated project costs are evaluated for impairment consistent with our impairment policies 
for long-lived assets. Capitalized costs are allocated to the specific components of a project that are benefited. 

56 

 
 
 
Table of Contents 

Index to Financial Statements 

Useful lives of assets. We are required to make subjective assessments as to the useful lives of our properties for purposes of determining the amount of depreciation to record on an 

annual basis with respect to our investments in real estate. These assessments have a direct impact on our net income because if we were to shorten the expected useful lives of our 
investments in real estate we would depreciate such investments over fewer years, resulting in more depreciation expense and lower net income on an annual basis. 

Asset impairment evaluation. We review each of our properties for indicators that its carrying amount may not be recoverable. Examples of such indicators may include a significant 

decrease in the market price of the property, a change in the expected holding period for the property, a significant adverse change in the extent or manner in which the property is being 
used in its physical condition or expected to be used based on the underwriting at the time of acquisition, an accumulation of costs significantly in excess of the amount originally expected 
for the acquisition or development of the property, or a history of operating or cash flow losses of the property. When such impairment indicators exist, we review an estimate of the future 
undiscounted net cash flows (excluding interest charges) expected to result from the real estate investment’s use and eventual disposition and compare that estimate to the carrying value of 
the property. We consider factors such as future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If our future undiscounted 
net cash flow evaluation indicates that we are unable to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds 
the estimated fair value of the property. These losses have a direct impact on our net income because recording an impairment loss results in an immediate negative adjustment to net 
income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ 
materially from actual results in future periods. Since cash flows on properties considered to be long-lived assets to be held and used are considered on an undiscounted basis to determine 
whether the carrying value of a property is recoverable, our strategy of holding properties over the long-term directly decreases the likelihood of their carrying values not being recoverable 
and therefore requiring the recording of an impairment loss. If our strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized and 
such loss could be material. If we determine that the asset fails the recoverability test, the affected assets must be reduced to their fair value.  

We generally estimate the fair value of rental properties utilizing a discounted cash flow analysis that includes projections of future revenues, expenses and capital improvement costs 
that a market participant would use based on the highest and best use of the asset, which is similar to the income approach that is commonly utilized by appraisers. In certain cases, we may 
supplement this analysis by obtaining outside broker opinions of value. 

Revenue Recognition 

Rental revenue is recognized using the straight-line method over the terms of the tenant leases. Deferred rents included in our condensed consolidated balance sheets represent the 
aggregate excess of rental revenue recognized to date on a straight-line basis versus the contractual rental payments under the terms of the leases. Many of our leases contain provisions 
under which the tenants reimburse us for a portion of property operating expenses and real estate taxes incurred by us. However, we generally are not entitled to reimbursement of property 
operating expenses, other than utility expense, and real estate taxes under our leases for Turn-Key Flex® facilities. Such reimbursements are recognized in the period that the expenses are 
incurred. Lease termination fees are recognized over the remaining term of the lease, effective as of the date the lease modification is finalized, assuming collection is not considered 
doubtful. As discussed above, we recognize amortization of the value of acquired above or below-market tenant leases as a reduction of rental revenue in the case of above-market leases or 
an increase to rental revenue in the case of below-market leases.  

We must make subjective estimates as to when our revenue is earned and the collectability of our accounts receivable related to minimum rent, deferred rent, expense reimbursements, 

lease termination fees and other income. We specifically analyze accounts receivable and historical bad debts, tenant concentrations, tenant creditworthiness and current economic trends 
when evaluating the adequacy of the allowance for bad debts. These estimates have a direct impact on our net revenue because a higher bad debt allowance would result in lower net 
revenue, and recognizing rental revenue as earned in one period versus another would result in higher or lower net revenue for a particular period. 

Share-Based Awards 

We recognize compensation expense related to share-based awards. We generally amortize this compensation expense over the vesting period of the award. The calculation of the fair 
value of share-based awards is subjective and requires several assumptions over such items as expected stock volatility, dividend payments and future company results. These assumptions 
have a direct impact on our net income because a higher share-based awards amount would result in lower net income for a particular period.

Our property portfolio has experienced consistent and significant growth since the first property acquisition in January 2002. As a result of this growth, our period-to-period 
comparison of our financial performance focuses on the impact on our revenues and expenses resulting both from the property additions to our portfolio, as well as on a “same store” 
property basis (same store properties are properties that were owned as of December 31, 2012 and excludes 10 properties that were contributed to our joint venture with the PREI®-
managed fund in September 2013 and March 2014 and one property that was contributed to our joint venture with the GCEAR affiliate in September 2014 along with any properties that 
have been sold) and on a stabilized portfolio basis. Our stabilized portfolio includes properties owned as of December 31, 2012 with less than 5% of total rentable square feet under 
development and excludes properties that were undergoing, or were expected to undergo, development activities in 2013-2014 and properties sold or contributed to joint ventures. The 
following table identifies each of the properties in our portfolio acquired from January 1, 2012 through December 31, 2014.

Space under active development includes current base building and data center projects in progress. Space held for future development includes space held for future data center 
development, and excludes space under active development. 

Net rentable square feet at a building represents the current square feet at that building under lease as specified in the lease agreements plus management’s estimate of space 
available for lease based on engineering drawings. Net rentable square feet includes tenants’ proportional share of common areas but excludes development space. 

Occupancy rates exclude development space. For some of our properties, we calculate occupancy based on factors in addition to contractually leased square feet, including 
available power, required support space and common area. 

Represents a property held in an unconsolidated joint venture.

Comparison of the Year Ended December 31, 2014 to the Year Ended December 31, 2013 and Comparison of the Year Ended December 31, 2013 to the Year Ended December 31, 2012  

Portfolio 

As of December 31, 2014, our portfolio consisted of 131 properties, including 14 properties held as investments in unconsolidated joint ventures and developable land, with an 

aggregate of 24.6 million rentable square feet including 1.3 million square feet of space under active development and 1.2 million square feet of space held for future development 
compared to a portfolio consisting of 132 properties, including 12 properties held as investments in unconsolidated joint ventures and developable land, with an aggregate of 24.5 million 
rentable square feet including 1.8 million square feet of space under active development and 1.3 million square feet of space held for future development as of December 31, 2013 and a 
portfolio consisting of 109 properties, including three properties held as investments in unconsolidated joint ventures and developable land, with an aggregate of 23.3 million rentable 
square feet including 1.4 million square feet of space under active development and 2.0 million square feet of space held for future development as of December 31, 2012. The change in 
the number of properties in our portfolio reflects the acquisition of 15 properties in 2012 (in addition, three properties were placed into service in 2012 in which the land parcel was acquired 
prior to January 1, 2012), 7 properties in 2013 (in addition, one property was placed into service in 2013 in which the land parcel was acquired prior to January 1, 2013) and the sale of one 
property in 2014.

As shown by the same store and non-same store table below, the increases in rental revenues and tenant reimbursement revenues in the year ended December 31, 2014 compared to 
2013 were due to new leasing at our same store properties, including completed and leased development space, and acquisitions of properties. The increase in fee income in the non-same 
store pool was mainly due to fees earned from the joint ventures with the PREI®-managed fund and GCEAR. Other revenues changes in the periods presented were primarily due to tenant 
termination revenues. We acquired 0, 7 and 15 properties during the years ended December 31, 2014, 2013 and 2012, respectively. The following table shows revenues for non-same store 
(properties that were acquired after December 31, 2012 along with properties contributed to joint ventures and properties sold) and same store properties (all other properties) (in

Same store rental revenues increased for the year ended December 31, 2014 compared to the same period in 2013 primarily as a result of new leases at our properties during 2014, 
including leases of completed development space, the largest of which were for space in the Sentrum Portfolio, 43940 Digital Loudoun Plaza, 350 East Cermak Road and 2121 South Price 
Road. Same store growth was driven by the delivery of approximately 443,000 square feet of leased data center space from within our same store development platform during the last 12 
months. In our same store portfolio, we calculate the change in rental rates on renewals signed during the quarter as compared to the previous rent on that same space. During the twelve 
months ended December 31, 2014, the percentage increase was 12.4% on a GAAP basis. Same store rental revenues increased for the year ended December 31, 2014 as compared to the 
same period in 2013 as a result of the increase in rentable square feet of leased data center space. During the twelve months ended December 31, 2014, we also delivered approximately

square feet of un-leased data center space which was one of the drivers impacting occupancy which increased slightly to 93.2% as of December 31, 2014 from 92.6% as of December 31, 
2013. Same store tenant reimbursement revenues increased for the year ended December 31, 2014 as compared to the same period in 2013 primarily as a result of new leasing and higher 
utility and operating expenses being billed to our tenants, the largest occurrences of which were at the Sentrum Portfolio, 365 South Randolphville Road, 43940 Digital Loudoun Plaza and 
350 East Cermak Road. 

Excluding the effect of 11 properties contributed to our unconsolidated joint ventures and 6 Braham Street (sold in April 2014), non-same store properties revenues increased 
approximately $11.7 million for the year ended December 31, 2014 compared to the same period in 2013. For the year ended December 31, 2014, 1500 Towerview Road, 7401 E. Ben 
White Boulevard and 371 Gough Road contributed $6.3 million, or 79%, respectively, of the non-same store increase in rental revenues and tenant reimbursements compared to the same

Same store rental revenues increased for the year ended December 31, 2013 compared to the same period in 2012 primarily as a result of new leases at our properties during 2013, 
including leases of completed development space, the largest of which were for space in 29A International Business Park, 43940 Digital Loudoun Plaza, 98 Radnor Drive and 3825 NW 
Aloclek Place. Same store growth was driven by the delivery of approximately 585,000 square feet of leased data center space from within our same store development platform during the 
last 12 months. In our same store portfolio, we calculate the change in rental rates on renewals signed during the quarter as compared to the previous rent on that same space. During the 
twelve months ended December 31, 2013, the percentage increase was 17.6% on a GAAP basis. Same store rental revenues increased for the year ended December 31, 2013 as compared to 
the same period in 2012 as a result of the increase in rentable square feet of leased data center space. During the twelve months ended December 31, 2013, we also delivered approximately 
119,000 square feet of un-leased data center space which was one of the drivers impacting occupancy which decreased slightly to 91.2% as of December 31, 2013 from 93.3% as of 
December 31, 2012 along with certain leases expiring at one of our non-technical properties during 2013. Rental revenue included amounts earned from leases with The tel(x) Group, Inc., 
or tel(x), which was sold to an unrelated third party in 2011, of approximately $48.6 million and $45.7 million for the year ended December 31, 2013 and 2012, respectively. Same store 
tenant reimbursement revenues increased for the year ended December 31, 2013 as compared to the same period in 2012 primarily as a result of new leasing and higher utility and operating 
expenses being billed to our tenants, the largest occurrences of which were at 29A International Business Park, 365 South Randolphville Road and 350 East Cermak Road.  

Non-same store properties increases were caused by properties acquired during the period from January 1, 2012 to December 31, 2013. For the year ended December 31, 2013, the 
Sentrum Portfolio, 9333, 9355, 9377 Grand Avenue and 400 S. Akard contributed $56.3 million, or approximately 84%, of the total non-same store increase in total operating expenses 
(excluding construction management) compared to the same period in 2012.

As shown in the same store and non-same store table below, total expenses for the year ended December 31, 2014 increased compared to the same period in 2013 primarily as a result 

of higher utility rates in several of our properties along with development projects being placed into service leading to higher utility expense (included in rental property operating and 
maintenance) in 2014. The following table shows expenses for non-same store (properties that were acquired after December 31, 2012 along with properties contributed to joint ventures 
and properties sold) and same store properties (all other properties) (in thousands).

Interest expense on our global revolving credit facility and unsecured term loan is allocated on a specific property basis.

Same store rental property operating and maintenance expenses increased in the year ended December 31, 2014 compared to the same period in 2013 primarily as a result of higher 

consumption and utility rates in several of our properties along with development projects being placed into service leading to higher utility expense in 2014. In 2013, a non-cash $10.0 
million straight-line rent expense adjustment was recorded in rental property operating and maintenance expenses related to a lease amendment executed in September 2010, $7.5 million of 
this amount related to prior years. This adjustment was deemed to be immaterial to both the current year and prior year financial statements taken as a whole. 

Same store property taxes increased by approximately $3.7 million in the year ended December 31, 2014 compared to the same period in 2013, primarily as a result of higher 

supplemental property tax assessments at three of our properties in 2014. 

Same store depreciation and amortization expense increased by approximately $69.7 million in the year ended December 31, 2014 compared to the same period in 2013, principally 

because of depreciation of development projects that were placed into service in late 2013 and during 2014. 

General and administrative expenses increased by approximately $27.5 million in the year ended December 31, 2014 compared to the same period in 2013 primarily due to the growth 

of our company, with an increase in headcount from 784 in 2013 to 860 in 2014, resulting in additional compensation, along with higher professional fees, marketing expenses and $12.7 
million severance related to the departure of our former Chief Executive Officer, Michael Foust recorded in the year ended December 31, 2014. The severance was determined in 
accordance with the non-cause termination provisions of Mr. Foust’s existing employment agreement and applicable equity award agreements with the company. 

Same store interest expense decreased by approximately $25,000 for the year ended December 31, 2014 as compared to the same period in 2013 primarily as a result of interest on our 

2023 Notes that were issued in April 2014 partially offset by

Index to Financial Statements 

lower average outstanding mortgage loan balances during 2014 compared to 2013 primarily due to the repayment of the following mortgage loans: Clonshaugh Industrial Estate II (June 
2013), 1500 Space Park Drive (July 2013), Paul van Vlissingenstraat 16 (July 2013), Chemin de l’Epinglier 2 (July 2013), Mundells Roundabout (October 2013), Gyroscoopweg 2E-2F 
(October 2013) and 360 Spear Street (November 2013) along with the redemption of the 2029 Debentures in April 2014. During the years ended December 31, 2014 and 2013, we 
capitalized interest of approximately $20.4 million and $26.3 million, respectively. 

Excluding the effect of 11 properties contributed to our unconsolidated joint ventures (in 2013 and 2014) and 6 Braham Street (sold in April 2014), non-same store expenses 

(excluding construction management and transactions expenses) increased approximately $5.4 million for the year ended December 31, 2014, respectively, compared to the same period in 
2013. For the year ended December 31, 2014, 371 Gough Road, 7401 E. Ben White Boulevard, 1500 Towerview Road and 8201 E. Riverside Drive contributed $4.1 million, or 76% of the 
total non-same store increase in total operating expenses (excluding construction management and transactions expenses) compared to the same period in 2013. 

Transactions expense decreased by approximately $3.3 million in the year ended December 31, 2014 compared to the same period in 2013, principally because there have been no 

significant acquisitions in 2014 compared to the acquisition of seven properties in the year ended December 31, 2013.

General and administrative expenses for the year ended December 31, 2013 increased compared to the same period in 2013 primarily due to the growth of our company, which 

resulted in more employees, additional incentive compensation, and higher professional fees and marketing expenses.  

Same store interest expense increased for the year ended December 31, 2013 as compared to the same period in 2012 primarily as a result of higher average balances on our unsecured 
term loan (originally closed in April 2012), offset by lower average outstanding mortgage debt balances during 2013 compared to 2012 primarily due to the paydown of the following loans: 
114 Rue Ambroise Croizat (January 2012), Unit 9, Blanchardstown Corporate Park (January 2012), 1201 Comstock Street (April 2012), 2805 Lafayette Street (May 2012), 2805 Lafayette 
Street Mezzanine (May 2012), 1350 Duane Avenue/3080 Raymond Street (September 2012), Clonshaugh Industrial Estate II (June 2013), 1500 Space Park Drive (July 2013), Paul van 
Vlissingenstraat 16 (July 2013), Chemin de l’Epinglier 2 (July 2013), Mundells Roundabout (October 2013), Gyroscoopweg 2E-2F (October 2013) and 360 Spear Street (November 2013). 
During the years ended December 31, 2013 and 2012, we capitalized interest of approximately $26.3 million and $21.5 million, respectively.  

Non-same store increases were caused by properties acquired during the period from January 1, 2012 to December 31, 2013. For the year ended December 31, 2013, the Sentrum 

Portfolio, 9333, 9355, 9377 Grand Avenue and 400 S. Akard contributed $56.3 million, or approximately 84%, of the total non-same store increase in total operating expenses (excluding 
construction management) compared to the same period in 2012.  

Transactions expense decreased in the year ended December 31, 2013 compared to the same period in 2012, principally because of expenses related to the acquisitions of the Sentrum 

Portfolio and Paris Portfolio in 2012.  

The following table shows expenses for the years ended December 31, 2014 and 2013 for stabilized properties and pre-stabilized properties (all other properties) (in thousands).

Impairment of Investments in Real Estate  

We are currently in the process of identifying certain non-core investment properties we intend to sell as part of our capital recycling strategy. Our capital recycling program is 

designed to identify non-strategic and underperforming assets that can be sold to generate proceeds that will support the funding of our core investment activity. We expect our capital 
recycling initiative will likewise have a meaningfully positive impact on overall return on invested capital. During this process, we are evaluating the carrying value of certain investment 
properties identified for potential sale to ensure the carrying value is recoverable in light of a potentially shorter holding period. As a result of our evaluation, during the year ended 
December 31, 2014, we recognized $126.5 million of impairment losses on five properties located in the Midwest, Northeast and West regions. As of December 31, 2014, these properties 
do not meet the criteria to be classified as held for sale.  

Gain on Sale of Property  

During the year ended December 31, 2014, we recognized a gain on sale of property of $15.9 million, related to the disposition of 6 Braham Street, which sold for £25.0 million (or 

approximately $41.5 million based on the exchange rate as of April 7, 2014, the date of sale).  

Gain on Contribution of Properties to Unconsolidated Joint Ventures  

During the year ended December 31, 2014, we recognized gains of $95.4 million, respectively, related to the contribution of two properties to two unconsolidated joint ventures. We 

received net proceeds of approximately $178.9 million in connection with these two transactions and retained a 20% interest in each of the joint ventures.  

During the year ended December 31, 2013, we recognized a gain of $115.6 million related to the contribution of nine properties to an unconsolidated joint venture. We received net 

proceeds of approximately $328.6 million in connection with this transaction and retained a 20% interest in the joint venture.  

Liquidity and Capital Resources of the Parent Company 

In this “Liquidity and Capital Resources of the Parent Company” section and in the “Liquidity and Capital Resources of the Operating Partnership” section below, the term, our 

“parent company”, refers to Digital Realty Trust, Inc. on an unconsolidated basis, excluding our operating partnership. 

Analysis of Liquidity and Capital Resources 

Our parent company’s business is operated primarily through our operating partnership of which our parent company is the sole general partner and which it consolidates for financial 

reporting purposes. Because our parent company operates on a consolidated basis with our operating partnership, the section entitled “Liquidity and Capital Resources of the Operating 
Partnership” should be read in conjunction with this section to understand the liquidity and capital resources of our parent company on a consolidated basis and how our company is 
operated as a whole.  

Our parent company issues public equity from time to time, but does not otherwise generate any capital itself or conduct any business itself, other than incurring certain expenses in 

operating as a public company which are fully reimbursed by the operating partnership. Our parent company itself does not hold any indebtedness other than guarantees of the indebtedness 
of  

68 

 
 
 
 
 
 
 
Table of Contents 

Index to Financial Statements 

our operating partnership and certain of its subsidiaries, and its only material asset is its ownership of partnership interests of our operating partnership. Therefore, the consolidated assets 
and liabilities and the consolidated revenues and expenses of our parent company and our operating partnership are the same on their respective financial statements, except for immaterial 
differences related to cash, other assets and accrued liabilities that arise from public company expenses paid by our parent company. However, all debt is held directly or indirectly at the 
operating partnership level. Our parent company’s principal funding requirement is the payment of dividends on its common and preferred shares. Our parent company’s principal source of 
funding for its dividend payments is distributions it receives from our operating partnership.  

As the sole general partner of our operating partnership, our parent company has the full, exclusive and complete responsibility for our operating partnership’s day-to-day 

management and control. Our parent company causes our operating partnership to distribute such portion of its available cash as our parent company may in its discretion determine, in the 
manner provided in our operating partnership’s partnership agreement. Our parent company receives proceeds from its equity issuances from time to time, but is generally required by our 
operating partnership’s partnership agreement to contribute the proceeds from its equity issuances to our operating partnership in exchange for partnership units of our operating 
partnership.  

Our parent company is a well-known seasoned issuer with an effective shelf registration statement filed on April 23, 2012 that allows our parent company to register an unspecified 

amount of various classes of equity securities. As circumstances warrant, our parent company may issue equity from time to time on an opportunistic basis, dependent upon market 
conditions and available pricing. Any proceeds from such equity issuances would be generally contributed to our operating partnership in exchange for additional equity interests in our 
operating partnership. Our operating partnership may use the proceeds to acquire additional properties, to fund development opportunities and for general working capital purposes, 
including potentially for the repurchase, redemption or retirement of outstanding debt or equity securities. 

The liquidity of our parent company is dependent on our operating partnership’s ability to make sufficient distributions to our parent company. The primary cash requirement of our 

parent company is its payment of dividends to its stockholders. Our parent company also guarantees our operating partnership’s, as well as certain of its subsidiaries’, unsecured debt. If our 
operating partnership or such subsidiaries fail to fulfill their debt requirements, which trigger parent company guarantee obligations, then our parent company will be required to fulfill its 
cash payment commitments under such guarantees. However, our parent company’s only asset is its investment in our operating partnership.  

We believe our operating partnership’s sources of working capital, specifically its cash flow from operations, and funds available under its global revolving credit facility are adequate 

for it to make its distribution payments to our parent company and, in turn, for our parent company to make its dividend payments to its stockholders. However, we cannot assure you that 
our operating partnership’s sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including making distribution payments to our parent company. 
The lack of availability of capital could adversely affect our operating partnership’s ability to pay its distributions to our parent company, which would in turn, adversely affect our parent 
company’s ability to pay cash dividends to its stockholders. 

Digital Realty Trust, Inc. entered into equity distribution agreements in June 2011, which we refer to as the 2011 Equity Distribution Agreements, with each of Merrill Lynch, Pierce, 

Fenner & Smith Incorporated, Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and Morgan Stanley & Co. LLC, or the Agents, under 
which it can issue and sell shares of its common stock having an aggregate offering price of up to $400.0 million from time to time through, at its discretion, any of the Agents as its sales 
agents. The sales of common stock made under the 2011 Equity Distribution Agreements will be made in “at the market” offerings as defined in Rule 415 of the Securities Act. To date, 
Digital Realty Trust, Inc. has generated net proceeds of approximately $342.7 million from the issuance of approximately 5.7 million common shares under the 2011 Equity Distribution 
Agreements at an average price of $60.35 per share after payment of approximately $3.5 million of commissions to the sales agents and before offering expenses. No sales were made under 
the program during the years ended December 31, 2014 and 2013. As of December 31, 2014, shares of common stock having an aggregate offering price of $53.8 million remained 
available for offer and sale under the program. 

On March 26, 2014 and April 7, 2014, our parent company issued an aggregate of 14.6 million shares of its 7.375% Series H Cumulative Redeemable Preferred Stock for total net 

proceeds, after underwriting discounts and estimated offering expenses, of $353.3 million, including the proceeds from the partial exercise of the underwriters’ over-allotment option. We 
used the net proceeds from the offerings to temporarily repay borrowings under our global revolving credit facility.  

On April 1, 2014, Digital Stout Holding, LLC, a wholly owned subsidiary of Digital Realty Trust, L.P, issued £300.0 million (or approximately $498.9 million based on the April 1, 
2014 exchange rate of £1.00 to $1.66) aggregate principal amount of its 4.750% Guaranteed Notes due 2023, or the 2023 notes. The 2023 notes are senior unsecured obligations of Digital 
Stout Holding, LLC and are fully and unconditionally guaranteed by Digital Realty Trust, Inc. and Digital Realty Trust, L.P. Interest on the 2023 notes is payable semiannually in arrears at 
a rate of 4.750% per annum. The 2023 notes will mature on

October 13, 2023. We used the net proceeds from the offering of the 2023 notes to temporarily repay borrowings under our global revolving credit facility.  

On April 18, 2014, the Operating Partnership redeemed for cash approximately $5.2 million in aggregate principal amount of the 2029 Debentures pursuant to its option under the 
indenture governing the 2029 Debentures at a price equal to 100% of the principal amount plus accrued and unpaid interest thereon up to April 18, 2014. In connection with the redemption, 
the holders of approximately $261.2 million in aggregate principal amount of the 2029 Debentures exchanged such 2029 Debentures for an aggregate of 6,734,938 restricted shares of 
Digital Realty Trust, Inc. common stock pursuant to the terms of the indenture governing the 2029 Debentures.  

On July 11, 2014, we issued an aggregate of 134,974 restricted shares of common stock of Digital Realty Trust, Inc. in exchange for approximately $5.2 million in cash to certain 

previous holders of the 2029 Debentures. The holders had the right to exchange the 2029 Debentures for shares of Digital Realty Trust, Inc. common stock, but inadvertently failed to 
exercise such rights. As a result, the 2029 Debentures were redeemed by the operating partnership for cash. We agreed to issue the restricted shares of the common stock to the holders in 
exchange for the redemption payment that they received in the original redemption, effectively putting such holders in the same place as if they had originally exercised their rights to 
exchange their 2029 Debentures for the shares of Digital Realty Trust, Inc. common stock. 

Future Uses of Cash 

Our parent company may from time to time seek to retire, redeem or repurchase its equity or the debt securities of our operating partnership through cash purchases and/or exchanges 

for equity securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases, redemptions or exchanges, if any, will depend on prevailing market 
conditions, our liquidity requirements, contractual restrictions or other factors. The amounts involved may be material.  

We are also subject to the commitments discussed below under “Dividends and Distributions.” 

Dividends and Distributions 

Our parent company is required to distribute 90% of its taxable income (excluding capital gains) on an annual basis in order for it to continue to qualify as a REIT for federal income 

tax purposes. Accordingly, our parent company intends to make, but is not contractually bound to make, regular quarterly distributions to its common stockholders from cash flow from our 
operating partnership’s operating activities. While historically our parent company has satisfied this distribution requirement by making cash distributions to its stockholders, it may choose 
to satisfy this requirement by making distributions of cash or other property. All such distributions are at the discretion of our parent company’s board of directors. Our parent company 
considers market factors and our operating partnership’s performance in addition to REIT requirements in determining distribution levels. Our parent company has distributed at least 100% 
of its taxable income annually since inception to minimize corporate level federal income taxes. Amounts accumulated for distribution to stockholders are invested primarily in interest-
bearing accounts and short-term interest-bearing securities, which are consistent with our intention to maintain our parent company’s status as a REIT.  

As a result of this distribution requirement, our operating partnership cannot rely on retained earnings to fund its on-going operations to the same extent that other companies whose 

parent companies are not REITs can. Our parent company may need to continue to raise capital in the debt and equity markets to fund our operating partnership’s working capital needs, as 
well as potential developments at new or existing properties, acquisitions or investments in existing or newly created joint ventures. In addition, our parent company may be required to use 
borrowings under our operating partnership’s global revolving credit facility, if necessary, to meet REIT distribution requirements and maintain our parent company’s REIT status.  

Our parent company has declared the following dividends on its common and preferred stock for the years ended December 31, 2014, 2013 and 2012 (in thousands):

Distributions out of our parent company’s current or accumulated earnings and profits are generally classified as ordinary income whereas distributions in excess of our company’s 

current and accumulated earnings and profits, to the extent of a stockholder’s U.S. federal income tax basis in our parent company’s stock, are generally classified as a return of capital. 
Distributions in excess of a stockholder’s U.S. federal income tax basis in our parent company’s stock are generally characterized as capital gain. Cash provided by operating activities has 
been generally sufficient to fund distributions on an annual basis, however, we may also need to utilize borrowings under the global revolving credit facility to fund distributions. 

The expected tax treatment of distributions paid on our parent company’s common and preferred stock paid in 2014 is as follows: approximately 82% ordinary income and 18% 
capital gain distribution. The tax treatment of distributions paid on our parent company’s common and preferred stock paid in 2013 was as follows: approximately 75% ordinary income and 
25% capital gain distribution. The tax treatment of distributions paid on our parent company’s common stock paid in 2012 was as follows: approximately 91% ordinary income, 8% return 
of capital and 1% capital gain distribution. The tax treatment of distributions paid on our parent company’s preferred stock paid in 2012 was as follows: approximately 99% ordinary 
income and 1% capital gain distribution.

Liquidity and Capital Resources of the Operating Partnership 

In this “Liquidity and Capital Resources of the Operating Partnership” section, the terms “we”, “our” and “us” refer to our operating partnership together with its consolidated 

subsidiaries or our operating partnership and our parent company together with their consolidated subsidiaries, as the context requires. 

Analysis of Liquidity and Capital Resources 

Our parent company is our sole general partner and consolidates our results of operations for financial reporting purposes. Because we operate on a consolidated basis with our parent 
company, the section entitled “Liquidity and Capital Resources of the Parent Company” should be read in conjunction with this section to understand our liquidity and capital resources on 
a consolidated basis.  

As of December 31, 2014, we had $41.3 million of cash and cash equivalents, excluding $11.6 million of restricted cash. Restricted cash primarily consists of interest-bearing cash deposits 
required by the terms of several of our mortgage loans for a variety of purposes, including real estate taxes, insurance, anticipated or contractually obligated tenant improvements, as well as 
capital expenditures.  

Our short-term liquidity requirements primarily consist of operating expenses, development costs and other expenditures associated with our properties, distributions to our parent company 
in order for it to make dividend payments on its preferred stock, distributions to our parent company in order for it to make dividend payments to its stockholders required to maintain its 
REIT status, distributions to the unitholders in our operating partnership, capital expenditures, debt service on our loans and, potentially, acquisitions. We expect to meet our short-term 
liquidity requirements through net cash provided by operations, restricted cash accounts established for certain future payments and by drawing upon our global revolving credit facility.  

On August 15, 2013, we refinanced our global revolving credit facility, increasing the total borrowing capacity to $2.0 billion from $1.8 billion. The global revolving credit facility has an 
accordion feature that would enable us to increase the borrowing capacity of the credit facility to $2.55 billion, subject to the receipt of lender commitments and other conditions precedent. 
The refinanced facility matures on November 3, 2017, with two six-month extension options available. The interest rate for borrowings under the expanded facility equals the applicable 
index plus a margin which is based on the credit ratings of our long-term debt and is currently 110 basis points. An annual facility fee on the total commitment amount of the facility, based 
on the credit rating of our long-term debt and currently 20 basis points, is payable quarterly. Funds may be drawn in U.S., Canadian, Singapore, Australian and Hong Kong dollars, as well 
as Euro, British pound sterling, Swiss franc, Japanese yen and Mexican peso denominations. As of December 31, 2014, borrowings under the global revolving credit facility bore interest at 
an overall blended rate of 1.84% comprised of 1.27% (U.S. dollars), 1.61% (British pound sterling), 1.13% (Euros), 3.74% (Australian dollars), 1.34% (Hong Kong dollars), 1.17% 
(Japanese yen), 1.64% (Singapore dollars) and 2.39% (Canadian dollars). The interest rates are based on 1-month LIBOR, 1-month EURIBOR, 1-month BBR, 1-month HIBOR, 1-month 
JPY LIBOR, 1-month SIDOR and 1-month CDOR, respectively, plus a margin of 1.10%. The facility also bore a base borrowing rate of 3.35% (USD) which is based on U.S. Prime Rate 
plus a margin of 0.10%. We have used and intend to use borrowings under the global revolving credit facility to acquire additional properties, fund development opportunities and to 
provide for working capital and other corporate purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or equity securities. As of December 31, 
2014, we have capitalized approximately $18.0 million of financing costs related to the global revolving credit facility. As of December 31, 2014, approximately $526.0 million was drawn 
under this facility and $9.3 million of letters of credit were issued, leaving approximately $1.4 billion available for use.  

On August 15, 2013, we refinanced the senior unsecured multi-currency term loan facility, increasing its total borrowing capacity to $1.0 billion from $750.0 million. Pursuant to the 
accordion feature, total commitments can be increased to $1.1 billion, subject to the receipt of lender commitments and other conditions precedent. The facility matures on April 16, 2017, 
with two six-month extension options available. Interest rates are based on our senior unsecured debt ratings and are currently 120 basis points over the applicable index for floating rate 
advances. Funds may be drawn in U.S, Singapore and Australian dollars, as well as Euro and British pound sterling denominations with the option to add Hong Kong dollars and Japanese 
yen upon an accordion exercise. Based on exchange rates in effect at December 31, 2014, the balance outstanding is approximately $1.0 billion. We have used borrowings under the term 
loan for acquisitions, repayment of indebtedness, development, working capital and general corporate purposes. The covenants under the term loan facility are consistent with our global 
revolving credit facility and, as of December 31, 2014, we were in compliance with all of such covenants. As of December 31, 2014, we have capitalized approximately $8.4 million of 
financing costs related to the unsecured term loan.  

For a discussion of the potential impact of current global economic and market conditions on our liquidity and capital resources, see “—Factors Which May Influence Future Results of 
Operations—Global market and economic conditions” above.  

Our parent company entered into equity distribution agreements in June 2011, which is discussed under “Liquidity and Capital Resources of the Parent Company” above. To date, our 
parent company has generated net proceeds of approximately $342.7

million from the issuance of approximately 5.7 million shares of common stock under the 2011 Equity Distribution Agreements at an average price of $60.35 per share after payment of 
approximately $3.5 million of commissions to the sales agents before offering expenses. The proceeds from the issuances were contributed to us in exchange for the issuance of 
approximately 5.7 million common units to our parent company. No sales were made under the program during the years ended December 31, 2014 and 2013. As of December 31, 2014, 
shares of common stock having an aggregate offering price of $53.8 million remained available for offer and sale under the program.  

On March 5, 2014, we contributed the 636 Pierce Street property, which we acquired in December 2013, to our unconsolidated joint venture with a fund managed by Prudential Real Estate 
Investors (PREI®) that was formed in September 2013. The property was valued at approximately $40.4 million and subject to $26.1 million in debt, which the joint venture assumed. The 
PREI® fund contributed approximately $11.4 million in cash for their 80% share of the net asset value of $14.3 million. Subsequent to the closing, the joint venture refinanced the existing 
debt with $23.0 million drawn from the joint venture’s bank facility. Including the refinance costs, the PREI® fund contributed $17.5 million for the 636 Pierce Street property, bringing 
their contributed capital in the joint venture to $164.8 million. We recognized a gain of approximately $1.9 million on the sale of the 80% interest during the three months ended March 31, 
2014. 

On April 7, 2014, the Operating Partnership sold 6 Braham Street to the tenant pursuant to a sale of the ownership interests in the Operating Partnership’s wholly owned subsidiary that 
owned the building for £25.0 million (or approximately $41.5 million based on the exchange rate as of April 7, 2014). The transaction after costs and various tenant prepayments resulted in 
net proceeds of approximately £22.6 million (or approximately $37.5 million based on the exchange rate as of April 7, 2014) and a net gain of approximately $15.9 million.  

On September 9, 2014, we formed a joint venture with an affiliate of Griffin Capital Essential Asset REIT, Inc. (GCEAR). We contributed to the joint venture the property located at 43915 
Devin Shafron Drive (Building A) in Ashburn, Virginia, which is a Turn-Key Flex® data center property valued at approximately $185.5 million (excluding approximately $2.1 million of 
closing costs). GCEAR contributed cash to the joint venture and will hold an 80% interest in the joint venture. We retained a 20% interest in the joint venture. The joint venture arranged a 
$102.0 million five-year secured bank loan at LIBOR plus 225 basis points, representing a loan-to-value ratio of approximately 55%. The joint venture entered into an interest rate swap 
agreement to effectively fix the interest rate on approximately $51.0 million of borrowings under the loan through September 2019. Two one-year extensions of the maturity date are 
available under the loan agreement, which the joint venture may exercise if certain conditions are met. Proceeds from this loan offset the initial cash capital contribution amount required 
from GCEAR and was used to provide us with a special distribution on account of a portion of the contribution value of the property. The transaction generated approximately $167.5 
million of net proceeds to us, comprised of our share of the initial draw-down on the bank loan in addition to GCEAR’s equity contribution, less our share of closing costs. Accordingly we 
recognized a gain of approximately $93.5 million on the sale of the 80% interest in the joint venture during the year ended December 31, 2014.  

On October 17, 2014, we closed on the sale of our $17.1 million investment in a developer of data centers in the Southwestern U.S. and Mexico, generating net proceeds of approximately 
$31.7 million. We recognized a gain on sale of approximately $14.6 million.  

The growing acceptance by private institutional investors of the data center asset class has generally pushed capitalization rates lower; as such private investors typically have lower return 
expectations than we do. As a result, we anticipate that near-term acquisitions activity will comprise a smaller percentage of our growth until seller price expectations realign with our return 
requirements.

Land inventory and space held for development reflect cumulative cost spent pending future development. Base building construction consists of ongoing improvements to building 

infrastructure in preparation for future datacenter fit-out. Datacenter construction includes 0.6 million square feet of Turn Key Flex®, Powered Base Building®, and Custom Solutions 
product with a cost to date of approximately $370.0 million. Generally, we expect to deliver the space within 12 months; however, lease commencement dates may significantly impact 
final delivery schedules. Equipment pool and other inventory represent the value of long-lead equipment and materials required for timely deployment and delivery of datacenter 
construction fit-out. Campus, tenant improvements and other costs include the value of development work which benefits space recently converted to our operating portfolio and is 
composed primarily of shared infrastructure projects and first generation tenant improvements. 

In May 2013, we received insurance settlement proceeds of approximately $8.6 million related to disputed construction costs, a portion of which has been recorded as a gain on 

settlement in our consolidated income statement included elsewhere in this report. 

Future Uses of Cash 

Our properties require periodic investments of capital for tenant-related capital expenditures and for general capital improvements. As of December 31, 2014, we had approximately 

1.3 million square feet of space under active development and approximately 1.2 million square feet of space held for future development and we also owned approximately 0.6 million net 
rentable square feet of datacenter space with extensive installed tenant improvements. Turn-Key Flex® space is move-in-ready space for the placement of computer and network equipment 
required to provide a datacenter environment. Depending on demand for additional Turn-Key Flex® space, we expect to incur significant tenant improvement costs to build out and develop 
these types of spaces. At December 31, 2014, the approximate 1.3 million square feet of space under active development was under construction for Turn-Key Flex®, Powered Base 
Building® and Custom Solutions (formerly referred to as Build-to-Suit) products, all of which are expected to be income producing on or after completion, in five U.S. domestic markets, 
one European market, one Canadian market, two Australian markets and our Singapore market, consisting of approximately 0.7 million square feet of base building construction and 0.6 
million square feet of data center construction. At December 31, 2014, we had commitments under construction contracts for approximately $156.5 million. We currently expect to incur 
approximately $750.0 million to $850.0 million of capital expenditures for our development programs during the year ending December 31,

For the year ended December 31, 2014, total capital expenditures decreased $286.4 million to approximately $804.8 million from $1,091.2 million for the same period in 2013. 
Capital expenditures on our development projects plus our enhancement and improvements projects for the year ended December 31, 2014 were approximately $752.2 million, which 
reflects a decrease of approximately 28% from the same period in 2013. This decrease was primarily due to completion of and decreased spending for ground-up Custom Solutions projects, 
Turn-Key Flex and base building improvements. Our development capital expenditures are generally funded by our available cash and equity and debt capital.  

Indirect costs, including capitalized interest, capitalized in the years ended December 31, 2014 and 2013 were $70.5 million and $64.7 million, respectively. Capitalized interest 
comprised approximately $20.4 million and $26.3 million, respectively, of the total indirect costs capitalized for the years ended December 31, 2014 and 2013. Capitalized interest in the 
year ended December 31, 2014 decreased compared to the same period in 2013 due to a reduction in qualifying activities. Excluding capitalized interest, the increase in indirect costs in the 
year ended December 31, 2014 compared to the same period in 2013 was primarily due to capitalized amounts relating to compensation expense of employees directly engaged in 
construction and leasing activities. See “—Future Uses of Cash” above for a discussion of the amount of capital expenditures we expect to incur during the year ending December 31, 2015. 

The environmental cleanup work required at the 47700 Kato Road and 1055 Page Avenue property resulting from a prior tenant’s activities has been completed. The prior tenant of 

these buildings completed most of the remaining required environmental cleanup work.  We intend to seek recovery of past costs incurred for previous environmental cleanup work, as well 
as other damages.  We cannot at this time estimate the likelihood of recovery or the impact on our financial condition and results of operations, however, the amounts are not expected to be 
material. 

We are also subject to the commitments discussed below under “Commitments and Contingencies,” “Off-Balance Sheet Arrangements” and “Distributions.” 

We actively pursue opportunities for potential acquisitions, with due diligence and negotiations often at different stages at different times. The dollar value of acquisitions for the year 

ending December 31, 2015 will be based on numerous factors, including tenant demand, leasing results, availability of debt or equity capital and acquisition opportunities.  

We may from time to time seek to retire or repurchase our outstanding debt or the equity of our parent company through cash purchases and/or exchanges for equity securities of our 
parent company in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity 
requirements, contractual restrictions or other factors. The amounts involved may be material.  

We expect to meet our short- and long-term liquidity requirements, including to pay for scheduled debt maturities and to fund property acquisitions and non-recurring capital 
improvements, with net cash from operations, future long-term secured and unsecured indebtedness and the issuance of equity and debt securities and the proceeds of equity issuances by 
our parent company. We also may fund future short- and long-term liquidity requirements, including property acquisitions and non-recurring capital improvements using our global 
revolving credit facility pending permanent financing. If we are not able to obtain additional financing on terms attractive to us, or at all, including as a result of the circumstances described 
above under “Factors Which May Influence Future Results of Operations—Global market and economic conditions”, we may be required to reduce our acquisition or capital expenditure 
plans, which could have a material adverse effect upon our business and results of operations.

Properties Acquired During 2014 

On September 16, 2014, we completed the acquisition of an approximate 13 acre vacant land parcel in the London metropolitan area for a purchase price of approximately of £14.1 

million (equivalent to approximately $23.0 million based on the September 16, 2014 exchange rate of £1.00 to $1.63). The acquisition was financed with borrowings under our global 
revolving credit facility.

Commitments and Contingencies 

As part of the 29A International Business Park asset acquisition in 2010, the seller could earn additional consideration based on future net operating income growth in excess of 
certain performance targets, as defined in the agreements for the acquisition. As of December 31, 2014, certain leases executed subsequent to purchase have caused an amount to become 
probable of payment and therefore approximately $12.6 million has been accrued in accounts payable and accrued liabilities and capitalized to buildings and improvements in the 
consolidated balance sheet as of December 31, 2014. The maximum amount that could be earned by the seller is $50.0 million SGD (or approximately $37.7 million based on the exchange 
rate as of December 31, 2014). The earnout contingency expires in November 2020. 

One of the tenants at our Convergence Business Park property has an option to expand as part of their lease agreement, which expires in April 2017. As part of this option, 

development activities were not permitted on specifically identified expansion space within the property until April 2014. From April 2014 through April 2017, the tenant has the right of 
first refusal on any third party’s bona fide offer to buy the adjacent land. If the tenant exercises their option, we may either construct and lease to the tenant an additional shell building on 
the expansion space at a stipulated rate of return on cost or sell the existing building and the expansion space to the tenant for a price of approximately $24.0 million and $225,000 per 
square acre, respectively, plus additional adjustments as provided in the lease. 

As part of the acquisition of the Sentrum Portfolio, the seller could earn additional consideration based on future net returns on vacant space to be developed, but not currently leased, 
as defined in the purchase agreement for the acquisition. The initial estimate of fair value of the contingent consideration liability was approximately £56.5 million (or approximately $87.6 
million based on the exchange rate as of July 11, 2012, the acquisition date). We have adjusted the contingent consideration to fair value at each reporting date with changes in fair value 
recognized in operating income. At December 31, 2014, the fair value of the contingent consideration for Sentrum was £30.3 million (or approximately $47.2 million based on the exchange 
rate as of December 31, 2014) and is currently accrued in accounts payable and other accrued expenses in the consolidated balance sheet. We made earnout payments of approximately £6.2 
million (or approximately $10.3 million based on the exchange rates as of the date of each payment) during the year ended December 31, 2014. During the year ended December 31, 2013, 
we made earnout payments of approximately £16.9 million (or approximately $25.8 million based on the exchange rates as of the date of each payment). From the acquisition date through 
December 31, 2014, we have made earnout payments of approximately £23.1 million (or approximately $36.1 million based on the exchange rates as of the date of each payment). The 
change in fair value of contingent consideration for Sentrum was recorded as a reduction to operating expense of approximately $8.4 million, $1.8 million and $1.1 million for the years 
ended December 31, 2014, 2013 and 2012, respectively. The fair value of this liability will be reassessed on a quarterly basis, with any changes being recognized in earnings. Increases or 
decreases in the fair value of the liability can result from changes in discount periods, discount rates and probabilities that contingencies will be met. The earn-out contingency expires in 
July 2015.  

During the year ended December 31, 2014, we rescinded the terms of a separation arrangement entered into with a former executive asserting that he has breached certain of his 
obligations and is no longer entitled to payment of previously accrued severance benefits, including cash payments and the vesting of certain equity awards. The former executive disputes 
our right to withhold his severance benefits and contends that he has not breached his obligations. In the latter portion of 2014, the former executive filed a demand for arbitration, which we 
challenged. We subsequently filed a complaint against the former executive for breach of contract and other claims. The former executive has asserted counterclaims against us for breach 
of contract and other claims. We cannot assure you of the outcome of this litigation. Should we prevail, however, some or all of the previously accrued severance cost may be reversed. We 
cannot estimate the potential expense recovery, if any, at this time. 

As of December 31, 2014, we were a party to interest rate swap agreements which hedge variability in cash flows related the U.S. LIBOR and SGD-SOR based tranches of the 

unsecured term loan. Under these swaps, we pay variable-rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal 
amounts. See Item 7A “Quantitative and Qualitative Disclosures about Market Risk.”

This is comprised of ground lease payments on 2010 East Centennial Circle, Chemin de l’Epinglier 2, Clonshaugh Industrial Estate I and II, Paul van Vlissingenstraat 16, 
Gyroscoopweg 2E-2F, Manchester Technopark and 29A International Business Park. After February 2036, rent for the remaining term of the 2010 East Centennial Circle ground 
lease will be determined based on a fair market value appraisal of the asset and, as a result, is excluded from the above information. After December 2036, rent for the remaining 
term of the Naritaweg 52 ground lease will be determined based on a fair market value appraisal of the asset and, as a result, is excluded from the above information. The Chemin 
de l’Epinglier 2 ground lease which expires in July 2074 contains potential inflation increases which are not reflected in the table above. The Paul van Vlissingenstraat 16, Chemin 
de l’Epinglier 2, Gyroscoopweg 2E-2F and Clonshaugh Industrial Estate I and II amounts are translated at the December 31, 2014 exchange rate of $1.21 to €1.00. The Manchester 
Technopark is translated at the December 31, 2014 exchange rate of $1.56 to £1.00. The 29A International Business Park is translated at the December 31, 2014 exchange rate of

Excludes impact of deferred financing cost amortization.

As of December 31, 2014, we had approximately $4.7 billion of outstanding consolidated long-term debt as set forth in the table above. Our ratio of debt to total enterprise value was 
approximately 31% (based on the closing price of Digital Realty Trust, Inc.’s common stock on December 31, 2014 of $66.30). For this purpose, our total enterprise value is defined as the 
sum of the market value of Digital Realty Trust, Inc.’s outstanding common stock (which may decrease, thereby increasing our debt to total enterprise value ratio), excluding options issued 
under our incentive award plan, plus the liquidation value of Digital Realty Trust, Inc.’s preferred stock, plus the aggregate value of our operating partnership’s units not held by Digital 
Realty Trust, Inc. (with the per unit value equal to the market value of one share of Digital Realty Trust, Inc.’s common stock and

excluding long-term incentive units, Class C Units and Class D Units), plus the book value of our total consolidated indebtedness.  

The variable rate debt shown above bears interest at interest rates based on various one-month LIBOR, EURIBOR, GBP LIBOR, SIBOR, BBR, HIBOR, JPY LIBOR, CDOR and 
U.S. Prime rates, depending on the respective agreement governing the debt, including our global revolving credit facility and unsecured term loan. As of December 31, 2014, our debt had 
a weighted average term to initial maturity of approximately 4.8 years (or approximately 5.1 years assuming exercise of extension options).  

Off-Balance Sheet Arrangements 

As of December 31, 2014, we were party to interest rate swap agreements related to $553.9 million of outstanding principal on our variable rate debt. See Item 7A “Quantitative and 

Qualitative Disclosures about Market Risk.” 

As of December 31, 2014, our pro-rata share of mortgage debt of unconsolidated joint ventures was approximately $137.8 million, of which $54.5 million is subject to interest rate 

swap agreements.

Cash provided by operating activities were consistent from 2014 to 2013 and increased in 2013 from 2012. The 2013 increase was due to increased revenues from new leasing at our 
same store properties, completed and leased development space and our acquisition of new operating properties which was partially offset by increased operating and interest expenses. We 
acquired 0, 7 and 15 properties during the years ended December 31, 2014, 2013 and 2012, respectively. 

Net cash used in investing activities decreased for 2014, as we had a decrease in cash paid for capital expenditures for the year ended December 31, 2014 ($852.4 million) as 
compared to the same period in 2013 ($1,189.5 million), along with a decrease in cash paid for acquisitions for the year ended December 31, 2014 ($24.3 million) as compared to in the 
same period in 2013 ($170.3 million). 

Net cash used in investing activities decreased in 2013 as compared to 2012, as we had a decrease in cash paid for acquisitions for the year ended December 31, 2013 ($170.3 million) 

as compared to the same period in 2012 ($1.6 billion) offset by an increase in cash paid for capital expenditures for the year ended December 31, 2013 ($1.2 billion) as compared to the 
same period in 2012 ($845.8 million). In addition, cash used in investing activities was lower in 2013 due to the contribution of properties to the joint venture with Prudential in September 
2013 ($328.6 million).

The decrease in net cash (used in) provided by financing activities was primarily due to the issuance of our 2025 Notes (net proceeds of $630.0 million) in January 2013 along with 

lower net repayments during the year ended December 31, 2013 (net proceeds of $2.1 million) as compared to the year ended December 31, 2014 (net repayments of $355.9 million) 
partially offset by the issuance of our 2023 Notes (net proceeds of $495.9 million) in April 2014. The increase in dividend and distribution payments for the year ended December 31, 2014 
as compared to the same period in 2013 was due to an increase in the number of shares outstanding and dividend amount per share of common stock in 2014 as compared to 2013 and the 
payment of dividends on series G preferred stock and series H preferred stock during the year ended December 31, 2014, whereas these series of preferred stock were not outstanding for 
the entire—or, in the case of the Series H preferred stock, any portion of—the year ended December 31, 2013. 

The decrease in net cash provided by financing activities was primarily due to higher net borrowings during the year ended December 31, 2012 (net proceeds of $991.8 million) as 
compared to the year ended December 31, 2013 (net proceeds of $2.1 million), the issuance of Digital Realty Trust, Inc.’s series F preferred stock in April 2012 (net proceeds of $176.2 
million) and common stock in its underwritten public offering in July 2012 (net proceeds of $797.2 million) along with the issuance of our 2022 Notes (net proceeds of $296.1 million) in 
September 2012 offset by the issuance of our 2025 Notes (net proceeds of $630.0 million) in January 2013 and Series G preferred stock (net proceeds of $241.5 million) in April 2013. The 
increase in dividend and distribution payments for the year ended December 31, 2013 as compared to the same period in 2012 was due to an increase in the number of shares outstanding 
and dividend amount per share of common stock in 2013 as compared to 2012 and the payment of dividends on our series F and series G preferred stock during the year ended 
December 31, 2013, which series of preferred stock were not outstanding for the entire—or, in the case of the Series G preferred stock, any portion of the— year ended December 31, 2012.

to the same period in 2013 was due to an increase in the number of units outstanding and distribution amount per common unit in 2014 as compared to 2013 and the payment of 
distributions on our series G preferred units and series H preferred units during the year ended December 31, 2014, whereas these series of preferred units were not outstanding for the 
entire—or, in the case of the Series H preferred units, any portion of—the year ended December 31, 2013. 

The decrease in net cash (used in) provided by financing activities was primarily due to higher net borrowings during the year ended December 31, 2012 (net proceeds of 
$991.8 million) as compared to the year ended December 31, 2013 (net proceeds of $2.1 million), general partner contributions in connection with Digital Realty Trust, Inc.’s series F 
preferred stock offering in April 2012 (net proceeds of $176.2 million) and common stock offering in July 2012 (net contributions of $797.2 million) and the issuance of our operating 
partnership’s 2022 Notes (net proceeds of $296.1 million) in September 2012 offset by the issuance of the 2025 Notes (net proceeds of $630.0 million) in January 2013 and general partner 
contributions in connection with Digital Realty Trust, Inc.’s series G preferred stock offering in April 2013 (net proceeds of $241.5 million). The increase in distribution payments for the 
year ended December 31, 2013 as compared to the same period in 2012 was due to an increase in the number of units outstanding and distribution amount per common unit in 2013 as 
compared to 2012 and the payment of distributions on our series F and series G preferred units during the year ended December 31, 2013, which series of preferred units were not 
outstanding for the entire—or, in the case of the Series G preferred units, any portion of the—year ended December 31, 2012. 

Noncontrolling Interests in Operating Partnership 

Noncontrolling interests relate to the common units in our operating partnership that are not owned by Digital Realty Trust, Inc., which, as of December 31, 2014, amounted to 2.2% 

of our operating partnership common units. In conjunction with our formation, our operating partnership issued common units to third party sellers in connection with our acquisition of real 
estate interests from such third parties.  

Limited partners who acquired common units in connection with our formation have the right to require our operating partnership to redeem part or all of their common units for cash 

based upon the fair market value of an equivalent number of shares of Digital Realty Trust, Inc. common stock at the time of the redemption. Alternatively, we may elect to acquire those 
common units in exchange for shares of Digital Realty Trust, Inc. common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock 
rights, specified extraordinary distributions and similar events. Pursuant to registration rights agreements we entered into with third party contributors, we filed a shelf registration statement 
covering the issuance of the shares of our common stock issuable upon redemption of the common units, and the resale of those shares of common stock by the holders. 

Inflation 

Many of our leases provide for separate real estate tax and operating expense escalations. In addition, many of the leases provide for fixed base rent increases. We believe that 

inflationary increases may be at least partially offset by the contractual rent increases and expense escalations described above.

Funds from Operations 

We calculate Funds from Operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts, or NAREIT. FFO represents 

net income (loss) available to common stockholders (computed in accordance with U.S. GAAP), excluding gains (or losses) from sales of property, impairment charges, real estate related 
depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a 
supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a performance 
measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance 
of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and 
captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and leasing commissions necessary to maintain the 
operating performance of our properties, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a 
measure of our performance is limited. Other REITs may not calculate FFO in accordance with the NAREIT definition and, accordingly, our FFO may not be comparable to such other 
REITs’ FFO. Accordingly, FFO should be considered only as a supplement to net income as a measure of our performance.

guidance.  ASU 2014-09 requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity
expects to be entitled in exchange for those goods or services and also requires certain additional disclosures.  ASU 2014-09 is effective for interim and annual reporting periods in fiscal 
years that begin after December 15, 2016.  We are currently evaluating the impact of the adoption of ASU 2014-09 on our consolidated financial statements. 

In June 2014, the FASB issued an update (ASU 2014-12) to ASC Topic 718, Compensation - Stock Compensation.  ASU 2014-12 requires an entity to treat performance targets that 
can be met after the requisite service period of a share based award has ended, as a performance condition that affects vesting.  ASU 2014-12 is effective for interim and annual reporting 
periods in fiscal years that begin after December 15, 2015.  We are currently evaluating the impact of the adoption of ASU 2014-12 on our consolidated financial statements.  

In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which provides guidance on the consolidation evaluation 
for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. In accordance with the guidance, all legal entities are subject to reevaluation 
under the revised consolidation model. The guidance is effective in the first quarter of 2016, and early adoption is permitted. We are currently evaluating the potential impact of the 
adoption of ASU 2015-02 on our consolidated financial statements.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

Our future income, cash flows and fair values relevant to financial instruments depend upon prevalent market interest rates. Market risk refers to the risk of loss from adverse changes in 
market prices and interest rates. We do not use derivatives for trading or speculative purposes and only enter into contracts with major financial institutions based on their credit rating and 
other factors. 

Analysis of Debt between Fixed and Variable Rate 

We use interest rate swap agreements and fixed rate debt to reduce our exposure to interest rate movements. As of December 31, 2014, our consolidated debt was as follows 

(in millions): 

Fixed rate debt 
Variable rate debt subject to interest rate swaps 
Total fixed rate debt (including interest rate swaps) 
Variable rate debt

Represents the U.S. dollar tranche of the unsecured term loan.

Represents a portion of the Singapore dollar tranche of the unsecured term loan. Translation to U.S. dollars is based on exchange rate of $0.75 to 1.00 SGD as of December 31, 
2014 and $0.79 to 1.00 SGD as of December 31, 2013. 

In January 2014, we entered into a forward-starting five-year swap contract to protect against adverse fluctuations in interest rates by reducing our exposure to variability in cash 
flows relating to interest payments on a forecasted issuance of debt. The accrual period of the swap contract was designed to match the tenor of the planned debt issuance. In the 
fourth quarter of 2014, changes in the forecasted transaction resulted in the discontinuation of cash flow hedge accounting. As such, changes in the fair value of the forward 
starting swap were recognized in earnings, within the other income (expense) line item.  During 2014 the total net gain recognized on the forward starting swap was approximately 
$0.8 million, and on January 13, 2015, we cash settled the forward starting swap for approximately $5.7 million, including accrued interest.

Sensitivity to Changes in Interest Rates 

The following table shows the effect if assumed changes in interest rates occurred, based on fair values and interest expense as of December 31, 2014: 

Assumed event 
Increase in fair value of interest rate swaps following an assumed 10% increase in interest rates 
Decrease in fair value of interest rate swaps following an assumed 10% decrease in interest rates 
Increase in annual interest expense on our debt that is variable rate and not subject to swapped interest following a 10% increase in interest 
rates 
Decrease in annual interest expense on our debt that is variable rate and not subject to swapped interest following a 10% decrease in interest 
rates 
Increase in fair value of fixed rate debt following a 10% decrease in interest rates 
Decrease in fair value of fixed rate debt following a 10% increase in interest rates

Interest risk amounts were determined by considering the impact of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in 

overall economic activity that could occur in that environment. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. 
However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure. 

Foreign Currency Exchange Risk 

For the years ended December 31, 2014 and 2013, we had foreign operations in the United Kingdom, Ireland, France, The Netherlands, Switzerland, Canada, Singapore, Australia, 

Japan and Hong Kong, and, as such, are subject to risk from the effects of exchange rate movements of foreign currencies, which may affect future costs and cash flows. Our foreign 
operations are conducted in the British pound sterling, Euro, Swiss franc, Australian dollar, Singapore dollar, Canadian dollar, Hong Kong dollar and the Japanese yen. Our primary 
currency exposures are to the British pound sterling, Euro and the Singapore dollar. We attempt to mitigate a portion of the risk of currency fluctuation by financing our investments in the 
local currency denominations, although there can be no assurance that this will be effective. As a result, changes in the relation of any such foreign currency to U.S. dollars may affect our 
revenues, operating margins and distributions and may also affect the book value of our assets and the amount of stockholders’ equity. For the years ended December 31, 2014, 2013 and 
2012, operating revenues from properties outside the United States contributed $383.0 million, $349.1 million and $228.9 million, respectively, which represented 23.7%, 23.6% and 17.9% 
of our operating revenues, respectively. Net investment in properties outside the United States was $2.7 billion and $2.7 billion as of December 31, 2014 and December 31, 2013, 
respectively. Net assets in foreign operations were approximately $0.7 billion and $1.2 billion as of December 31, 2014 and December 31, 2013, respectively. The decrease was a result of 
the issuance of the 2023 Notes in April 2014, the proceeds of which were used to pay down British pound sterling and U.S. dollar borrowings on the global revolving credit facility.

Management’s Report on Internal Control over Financial Reporting 

The management of Digital Realty Trust, Inc. (the Company) is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined 
in Exchange Act Rules 13a-15(f) and 15(d)-15(f). Our internal control system was designed to provide reasonable assurance to the Company’s management and board of directors regarding 
the preparation and fair presentation of published financial statements. 

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance 

with respect to financial statement preparation and presentation. 

Under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, we assessed the effectiveness of the Company’s 
internal control over financial reporting as of December 31, 2014. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway 
Commission in Internal Control—Integrated Framework (1992). Based on our assessment, management concluded that as of December 31, 2014, the Company’s internal control over 
financial reporting was effective based on those criteria. 

Our independent registered public accounting firm has issued an audit report on the Company’s internal control over financial reporting. This report appears on page 92.

Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (1992). Based on our assessment, management concluded that as of December 31, 
2014, the Operating Partnership’s internal control over financial reporting was effective based on those criteria.

Digital Realty Trust, Inc.: 

Report of Independent Registered Public Accounting Firm 

We have audited the accompanying consolidated balance sheets of Digital Realty Trust, Inc. (the Company) and subsidiaries as of December 31, 2014 and 2013, and the related 

consolidated income statements, statements of comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2014. In connection with 
our audits of the consolidated financial statements, we also have audited financial statement schedule III, properties and accumulated depreciation. These consolidated financial statements 
and financial statement schedule III are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and 
financial statement schedule III based on our audits. 

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Digital Realty Trust, Inc. and subsidiaries as of 

December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2014, in conformity with 
U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule III, properties and accumulated depreciation, when considered in relation to the 
basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Digital Realty Trust, Inc.’s internal control over financial 
reporting as of December 31, 2014, based on criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO), and our report dated March 2, 2015 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

The Board of Directors and Stockholders 
Digital Realty Trust, Inc.: 

Report of Independent Registered Public Accounting Firm 

We have audited Digital Realty Trust, Inc.’s (the Company) internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control—

Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining 
effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report 
on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. 

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

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of 

financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and 
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide 
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts 
and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future 
periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

In our opinion, Digital Realty Trust, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on criteria established 

in Internal Control – Integrated Framework (1992) issued by COSO. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Digital Realty Trust, 
Inc. and subsidiaries as of December 31, 2014 and 2013, and the related consolidated income statements, statements of comprehensive income, equity, and cash flows for each of the years 
in the three-year period ended December 31, 2014, and the financial statement schedule III, properties and accumulated depreciation, and our report dated March 2, 2015 expressed an 
unqualified opinion on those consolidated financial statements and financial statement schedule III.

DIGITAL REALTY TRUST, INC. AND SUBSIDIARIES 
DIGITAL REALTY TRUST, L.P. AND SUBSIDIARIES 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2014 and 2013 

1. Organization and Description of Business 

Digital Realty Trust, Inc. through its controlling interest in Digital Realty Trust, L.P. (the Operating Partnership) and the subsidiaries of the Operating Partnership (collectively, we, 
our, us or the Company) is engaged in the business of owning, acquiring, developing and managing technology-related real estate. The Company is focused on providing customer driven 
datacenter solutions for domestic and international tenants across a variety of industry verticals ranging from financial services, cloud and information technology services, to 
manufacturing, energy, health care and consumer products. As of December 31, 2014, our portfolio consisted of 131 properties, including 14 properties held as investments in 
unconsolidated joint ventures and developable land, of which 105 are located throughout North America, 21 are located in Europe, three are located in Australia and two are located in Asia. 
We are diversified in major markets where corporate datacenter and technology tenants are concentrated, including the Boston, Chicago, Dallas, Los Angeles, New York Metro, Northern 
Virginia, Phoenix, San Francisco and Silicon Valley metropolitan areas in the United States, Amsterdam, Dublin, London and Paris markets in Europe and Singapore, Sydney, Melbourne, 
Hong Kong and Osaka markets in the Asia Pacific region. The portfolio consists of Internet gateway and corporate datacenter properties, technology manufacturing properties and regional 
or national offices of technology companies. 

The Operating Partnership was formed on July 21, 2004 in anticipation of Digital Realty Trust, Inc.’s initial public offering (IPO) on November 3, 2004 and commenced operations 

on that date. As of December 31, 2014, Digital Realty Trust, Inc. owns a 97.8% common interest and a 100.0% preferred interest in the Operating Partnership. As sole general partner of the 
Operating Partnership, Digital Realty Trust, Inc. has the full, exclusive and complete responsibility for the Operating Partnership’s day-to-day management and control. The limited partners 
of the Operating Partnership do not have rights to replace Digital Realty Trust, Inc. as the general partner nor do they have participating rights, although they do have certain protective 
rights. 

2. Summary of Significant Accounting Policies 

(a) Principles of Consolidation and Basis of Presentation 

The accompanying consolidated financial statements include all of the accounts of Digital Realty Trust, Inc., the Operating Partnership and the subsidiaries of the Operating 

Partnership. Intercompany balances and transactions have been eliminated. 

The notes to the consolidated financial statements of Digital Realty Trust, Inc. and the Operating Partnership have been combined to provide the following benefits: 
• 

enhancing investors’ understanding of the Company and the Operating Partnership by enabling investors to view the business as a whole in the same manner as management 
views and operates the business; 

• 

• 

eliminating duplicative disclosure and providing a more streamlined and readable presentation since a substantial portion of the disclosure applies to both the Company and 
the Operating Partnership; and 

creating time and cost efficiencies through the preparation of one set of notes instead of two separate sets of notes.

There are few differences between the Company and the Operating Partnership, which are reflected in these consolidated financial statements. We believe it is important to 

understand the differences between the Company and the Operating Partnership in the context of how we operate as an interrelated consolidated company. Digital Realty Trust, Inc.’s only 
material asset is its ownership of partnership interests of the Operating Partnership. As a result, Digital Realty Trust, Inc. does not conduct business itself, other than acting as the sole 
general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain unsecured debt of the Operating Partnership and certain of its subsidiaries. 
Digital Realty Trust, Inc. itself does not hold any indebtedness but guarantees the unsecured debt of the Operating Partnership and certain of its subsidiaries, as disclosed in these notes. The 
Operating Partnership holds substantially all the assets of the Company and holds the ownership interests in the Company’s joint ventures. The Operating Partnership conducts the 
operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from public equity issuances by Digital Realty Trust, Inc., which are 
generally contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by the Company’s business through the 
Operating Partnership’s operations, by the Operating Partnership’s direct or indirect incurrence of indebtedness or through the issuance of partnership units.

DIGITAL REALTY TRUST, L.P. AND SUBSIDIARIES 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS- (Continued) 
December 31, 2014 and 2013 

The presentation of noncontrolling interests in operating partnership, stockholders’ equity and partners’ capital are the main areas of difference between the consolidated financial 

statements of Digital Realty Trust, Inc. and those of the Operating Partnership. The common limited partnership interests held by the limited partners in the Operating Partnership are 
presented as limited partners’ capital within partners’ capital in the Operating Partnership’s consolidated financial statements and as noncontrolling interests in operating partnership within 
equity in Digital Realty Trust, Inc.’s consolidated financial statements. The common and preferred partnership interests held by Digital Realty Trust, Inc. in the Operating Partnership are 
presented as general partner’s capital within partners’ capital in the Operating Partnership’s consolidated financial statements and as preferred stock, common stock, additional paid-in 
capital and accumulated dividends in excess of earnings within stockholders’ equity in Digital Realty Trust, Inc.’s consolidated financial statements. The differences in the presentations 
between stockholders’ equity and partners’ capital result from the differences in the equity issued at the Digital Realty Trust, Inc. and the Operating Partnership levels. 

To help investors understand the significant differences between the Company and the Operating Partnership, these consolidated financial statements present the following separate 

sections for each of the Company and the Operating Partnership: 

• 

• 

consolidated face financial statements; and

the following notes to the consolidated financial statements:

• 

• 

• 

• 

Debt of the Company and Debt of the Operating Partnership;

Income per Share and Income per Unit;

Equity and Accumulated Other Comprehensive Loss, Net of the Company and Capital and Accumulated Other Comprehensive Income (Loss) of the Operating 
Partnership; and 

Quarterly Financial Information.

In the sections that combine disclosure of Digital Realty Trust, Inc. and the Operating Partnership, these notes refer to actions or holdings as being actions or holdings of the 

Company. Although the Operating Partnership is generally the entity that enters into contracts and joint ventures and holds assets and debt, reference to the Company is appropriate because 
the business is one enterprise and the Company operates the business through the Operating Partnership. 

(b) Cash Equivalents 

For the purpose of the consolidated statements of cash flows, we consider short-term investments with original maturities of 90 days or less to be cash equivalents. As of 

December 31, 2014 and 2013, cash equivalents consist of investments in money market instruments. 

(c) Investments in Real Estate 

Investments in real estate are stated at cost, less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization are recorded on a straight-line 

basis over the estimated useful lives as follows: 

Acquired ground leases 
Buildings and improvements 
Tenant improvements 

    Terms of the related lease 
    5-39 years 
    Shorter of the estimated useful lives or the terms of the related leases 

Improvements and replacements are capitalized when they extend the useful life, increase capacity, or improve the efficiency of the asset. Repairs and maintenance are charged to 

expense as incurred. 

Assets that are classified as held for sale are recorded at the lower of their carrying value or fair value less costs to dispose. We classify assets as held for sale once management has 

the authority to approve and commits to a plan to sell, the assets are available for immediate sale, an active program to locate a buyer has commenced and the sale of the assets are probable 
and transfer of the assets are expected to occur within one year. Upon the classification of assets as held for sale or sold, the depreciation and amortization of the assets will cease.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS- (Continued) 
December 31, 2014 and 2013 

(d) Investment in Unconsolidated Joint Ventures 

The Company’s investment in unconsolidated joint ventures is accounted for using the equity method, whereby the investment is increased for capital contributed and our share of the 

joint ventures’ net income and decreased by distributions we receive and our share of any losses of the joint ventures.  

We amortize the difference between the cost of our investments in unconsolidated joint ventures and the book value of the underlying equity into equity in earnings from 

unconsolidated affiliates on a straight-line basis consistent with the lives of the underlying assets. 

(e) Impairment of Long-Lived Assets 

We review each of our properties for indicators that its carrying amount may not be recoverable. Examples of such indicators may include a significant decrease in the market price of 

the property, a significant adverse change in the extent or manner in which the property is being used in its physical condition or expected to be used based on the underwriting at the time 
of acquisition, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of the property, or a history of operating or cash flow 
losses of the property. When such impairment indicators exist, we review an estimate of the future probability weighted undiscounted net cash flows (excluding interest charges) expected 
to result from the real estate investment’s use and eventual disposition and compare that estimate to the carrying value of the property. We consider factors such as future operating income, 
trends and prospects, as well as the effects of leasing demand, competition, potential sales proceeds and other factors. If our undiscounted net cash flow evaluation indicates that we are 
unable to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property.  

In the third and fourth quarters of 2014, we identified certain properties in our portfolio that fall outside of our targeted investment strategy, which are candidates for near-term 
disposition. We have implemented a marketing strategy for those properties identified as held for sale as of December 31, 2014. We are in the process of developing our marketing strategy 
for those assets that did not meet the held for sale criteria as of December 31, 2014. We plan to carefully evaluate the disposition options revealed through our marketing efforts, and to 
pursue those which provide the best opportunity to optimize shareholder value. In connection with initiating this process, we evaluated the recoverability of the carrying values of each of 
these properties and determined that the carrying values of five properties was no longer recoverable due to reducing their expected holding period. As a result, for the year ended 
December 31, 2014, we reduced the carrying values of the properties to their estimated fair value by recording an impairment loss of approximately $126.5 million. Estimated fair value 
was determined using the guidance in ASC 820, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between 
market participants at the measurement date. There were no impairment losses for the years ended December 31, 2013 and 2012. 

(f) Purchase Accounting for Acquisition of Investments in Real Estate 

Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired from third parties. In accordance with current accounting guidance, the fair 
value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and tenant improvements, and identified intangible assets and liabilities, 
consisting of the value of above-market and below-market leases, other value of in-place leases, value of tenant relationships and acquired ground leases, based in each case on their fair 
values. Loan premiums, in the case of above market rate loans, or loan discounts, in the case of below market loans, are recorded based on the fair value of any loans assumed in connection 
with acquiring the real estate. 

The fair values of the tangible assets of an acquired property are determined based on comparable land sales for land and replacement costs adjusted for physical and market 
obsolescence for the improvements. The fair values of the tangible assets of an acquired property are also determined by valuing the property as if it were vacant, and the “as-if-vacant” 
value is then allocated to land, building and tenant improvements based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant 
fair value of a property based on assumptions that a market participant would use, which is similar to methods used by independent appraisers. Factors considered by management in 
performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating 
carrying costs, management includes real estate taxes, insurance and other  

116

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS- (Continued) 
December 31, 2014 and 2013 

operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates costs to execute similar leases 
including leasing commissions, tenant improvements, legal and other related costs. 

In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded based on the 

present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place 
leases and (ii) estimated fair market lease rates from the perspective of a market participant for the corresponding in-place leases, measured, for above-market leases, over a period equal to 
the remaining non-cancelable term of the lease and, for below-market leases, over a period equal to the initial term plus any below market fixed rate renewal periods. The leases we have 
acquired do not currently include any below market fixed rate renewal periods. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining 
non-cancelable terms of the respective leases. The capitalized below-market lease values, also referred to as acquired lease obligations, are amortized as an increase to rental income over 
the initial terms of the respective leases and any below market fixed rate renewal periods. 

In addition to the intangible value for above market leases and the intangible negative value for below market leases, there is intangible value related to having tenants leasing space in

the purchased property, which is referred to as in-place lease value and tenant relationship value. Such value results primarily from the buyer of a leased property avoiding the costs 
associated with leasing the property and also avoiding rent losses and unreimbursed operating expenses during the lease up period. The estimated avoided costs and avoided revenue losses 
are calculated and this aggregate value is allocated between in-place lease value and tenant relationships based on management’s evaluation of the specific characteristics of each tenant’s 
lease; however, the value of tenant relationships has not been separated from in-place lease value for our real estate because such value and its consequence to amortization expense is 
immaterial for these particular acquisitions. The value of in-place leases exclusive of the value of above-market in-place leases is amortized to expense over the estimated term (including 
renewal and extension assumptions) of the respective leases. If a lease were to be terminated prior to its estimated term, all unamortized amounts relating to that lease would be written off. 

(g) Capitalization of Costs 

Direct and indirect project costs that are clearly associated with the development of properties are capitalized as incurred. Project costs include all costs directly associated with the 

development of a property, including construction costs, interest, property taxes, insurance, legal fees and costs of personnel working on the project. Indirect costs that do not clearly relate 
to the projects under development are not capitalized and are charged to expense as incurred.  

Capitalization of costs begins when the activities necessary to get the development project ready for its intended use begins, which include costs incurred before the beginning of 

construction. Capitalization of costs ceases when the development project is substantially complete and ready for its intended use. Determining when a development project commences, 
and when it is substantially complete and ready for its intended use involves a degree of judgment. We generally consider a development project to be substantially complete and ready for 
its intended use upon receipt of a certificate of occupancy. If and when development of a property is suspended pursuant to a formal change in the planned use of the property, we will 
evaluate whether the accumulated costs exceed the estimated value of the project and write off the amount of any such excess accumulated costs. For a development project that is 
suspended for reasons other than a formal change in the planned use of such property, the accumulated project costs are evaluated for impairment consistent with our impairment policies 
for long-lived assets. Capitalized costs are allocated to the specific components of a project that are benefited. 

During the years ended December 31, 2014, 2013 and 2012, we capitalized interest of approximately $20.4 million, $26.3 million and $21.5 million, respectively. During the years 

ended December 31, 2014, 2013 and 2012, we capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of 
approximately $50.1 million, $38.4 million and $31.6 million, respectively. Cash flows used for capitalized leasing costs of $49.0 million, $57.5 million and $40.1 million are included in 
improvements to and advances for investments in real estate in cash flows from investing activities in the consolidated statements of cash flows for the years ended December 31, 2014, 
2013 and 2012, respectively.

December 31, 2014 and 2013 

(h) Deferred Leasing Costs 

Leasing commissions and other direct and indirect costs associated with the acquisition of tenants are capitalized and amortized on a straight line basis over the terms of the related 

leases. 

(i) Foreign Currency Translation 

Assets and liabilities of our subsidiaries outside the United States with non-U.S. dollar functional currencies are translated into U.S. dollars using exchange rates as of the balance 
sheet dates. Income and expenses are translated using the average exchange rates for the reporting period. Foreign currency translation adjustments are recorded as a component of other 
comprehensive income. 

(j) Deferred Financing Costs 

Loan fees and costs are capitalized and amortized over the life of the related loans on a straight-line basis, which approximates the effective interest method. Such amortization is 

included as a component of interest expense. 

(k) Restricted Cash 

Restricted cash consists of deposits for real estate taxes and insurance and other amounts as required by our loan agreements including funds for leasing costs and improvements 

related to unoccupied space. 

(l) Offering Costs 

Underwriting commissions and other offering costs are reflected as a reduction in additional paid-in capital, or in the case of preferred stock, as a reduction of the carrying value of 

preferred stock. 

(m) Share Based Compensation 

The Company measures all share-based compensation awards at fair value on the date they are granted to employees and directors, and recognizes compensation cost, net of 
forfeitures, over the requisite service period for awards with only a service condition. The estimated fair value of the long-term incentive units and Class D Units (discussed in note 13) 
granted by us is being amortized on a straight-line basis over the expected service period.  

The fair value of share-based compensation awards that contain a market condition is measured using a Monte Carlo simulation method and not adjusted based on actual achievement 

of the market condition. 

(n) Accounting for Derivative Instruments and Hedging Activities 

We account for our derivative instruments and hedging activities in accordance with the accounting standard for derivative and hedging activities. The accounting standard requires us 
to measure every derivative instrument (including certain derivative instruments embedded in other contracts) at fair value and record them in the balance sheet as either an asset or liability. 

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is 

subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is 
recognized directly in earnings. The amount of gain recognized in income related to the ineffective portion of the hedging relationships for the year ended December 31, 2014 was 
approximately $0.8 million. During the years ended December 31, 2013 and 2012, respectively, there were no ineffective portions to our interest rate swaps. 

We actively manage our ratio of fixed-to-floating rate debt. To manage our fixed and floating rate debt in a cost-effective manner, we, from time to time, enter into interest rate swap 

agreements as cash flow hedges, under which we agree to exchange various combinations of fixed and/or variable interest rates based on agreed upon notional amounts. We do not enter 
into derivative instruments for trading purposes.

Digital Realty Trust, Inc. has elected to be treated as a real estate investment trust (a “REIT”) for federal income tax purposes. As a REIT, Digital Realty Trust, Inc. generally is not 
required to pay federal corporate income tax to the extent taxable income is currently distributed to its stockholders. If Digital Realty Trust, Inc. fails to qualify as a REIT in any taxable 
year, it will be subject to federal income tax (including any applicable alternative minimum tax) on its taxable income at regular corporate tax rates.  

The Company is subject to foreign, state and local income taxes in the jurisdictions in which it conducts business. The Company’s U.S. consolidated taxable REIT subsidiaries are 

subject to both federal and state income taxes to the extent there is taxable income. Accordingly, the Company recognizes current and deferred income taxes for its taxable REIT 
subsidiaries, certain states and non-U.S. jurisdictions, as appropriate.  

We assess our significant tax positions in accordance with U.S. GAAP for all open tax years and determine whether we have any material unrecognized liabilities from uncertain tax 
benefits. If a tax position is not considered “more-likely-than-not” to be sustained solely on its technical merits, no benefits of the tax position are to be recognized (for financial statement 
purposes). As of December 31, 2014 and 2013, we have no assets or liabilities for uncertain tax positions. We classify interest and penalties from significant uncertain tax positions as 
interest expense and operating expense, respectively, in our consolidated income statements. For the years ended December 31, 2014, 2013 and 2012, we had no such interest or penalties. 
The tax year 2011 and thereafter remain open to examination by the major taxing jurisdictions with which the Company files tax returns. 

See Note 10 for further discussion on income taxes. 

(p) Presentation of Transactional-based Taxes 

We account for transactional-based taxes, such as value added tax, or VAT, for our international properties on a net basis. 

(q) Revenue Recognition 

All leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the terms of the leases. The excess of rents recognized over amounts 
contractually due pursuant to the underlying leases is included in deferred rent in the accompanying consolidated balance sheets and contractually due but unpaid rents are included in 
accounts and other receivables. 

Tenant reimbursements for real estate taxes, common area maintenance, and other recoverable costs are recognized in the period that the expenses are incurred. Lease termination 

fees, which are included in other revenue in the accompanying consolidated income statements, are recognized over the new remaining term of the lease, effective as of the date the lease 
modification is finalized, and assuming collection is probable. 

A provision for loss is made if the collection of the receivable balances related to contractual rent, rent recorded on a straight-line basis, tenant reimbursements and lease termination 

fees are considered to be doubtful. 

(r) Asset Retirement Obligations 

We record accruals for estimated retirement obligations as required by current accounting guidance. The amount of asset retirement obligations relates primarily to estimated asbestos 

removal costs at the end of the economic life of properties that were built before 1984. As of December 31, 2014 and 2013, the amount included in accounts payable and other accrued 
liabilities on our consolidated balance sheets was approximately $1.7 million and $1.7 million, respectively. 

(s) Fee Income 

Occasionally, customers engage the company for certain services. The nature of these services historically involves property management, construction management, and assistance 

with financing. The proper revenue recognition of these services can be different, depending on whether the arrangements are service revenue or contractor type revenue.  

Service revenues are typically recognized on an equal monthly basis based on the minimum fee to be earned. The monthly amounts could be adjusted depending on if certain 

performance milestones are met.

December 31, 2014 and 2013 

Fee income also includes management fees. These fees arise from contractual agreements with entities in which we have a noncontrolling interest. The management fees are 
recognized as earned under the respective agreements. Management and other fee income related to partially owned entities are recognized to the extent attributable to the unaffiliated 
interest.  

(t) Assets and Liabilities Measured at Fair Value 

Fair value under U.S. GAAP is a market-based measurement, not an entity-specific measurement. Therefore, our fair value measurements are determined based on the assumptions 

that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair-value measurements, we use a fair-value hierarchy that 
distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 
and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).  

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than 
quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active 
markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at 
commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability which are typically based on an entity’s own assumptions, as there is little, if any, related market 
activity. In instances where the determination of the fair-value measurement is based on inputs from different levels of the fair-value hierarchy, the lowest level input that is significant 
would be used to determine the fair-value measurement in its entirety. Our assessment of the significance of a particular input to the fair-value measurement in its entirety requires 
judgment, and considers factors specific to the asset or liability. 

(u) Transactions Expense 

Transactions expense includes acquisition-related expenses and other business development expenses, which are expensed as incurred. Acquisition-related expenses include closing 

costs, broker commissions and other professional fees, including legal and accounting fees related to acquisitions and significant transactions. 

(v) Management’s Estimates 

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and 

liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting 
period. Actual results could differ from those estimates made. On an on-going basis, we evaluate our estimates, including those related to the valuation of our real estate properties, 
contingent consideration, accounts receivable and deferred rent receivable, performance-based equity compensation plans and the completeness of accrued liabilities We base our estimates 
on historical experience, current market conditions, and various other assumptions that are believed to be reasonable under the circumstances. Actual results may vary from those estimates 
and those estimates could vary under different assumptions or conditions. 

(w) Segment and Geographic Information 

All of our properties generate similar revenues and expenses related to tenant rent and reimbursements and operating expenses. The delivery of our products is consistent across all 

properties and although services are provided to a wide range of customers, the types of real estate services provided to them are standardized throughout the portfolio. As such, the 
properties in our portfolio have similar economic characteristics and the nature of the products and services provided to our customers and the method to distribute such services are 
consistent throughout the portfolio. Consequently, our properties qualify for aggregation into one reporting segment. 

Operating revenues from properties in the United States were $1.2 billion, $1.1 billion and $1.1 billion and outside the United States were $383.0 million, $349.1 million and $228.9 
million for the years ended December 31, 2014, 2013 and 2012, respectively. We had long-lived assets located in the United States of $5.4 billion, $5.6 billion and $5.0 billion and outside 
the United States of $2.7 billion, $2.7 billion and $2.5 billion as of December 31, 2014, 2013 and 2012, respectively.

Operating revenues from properties located in the United Kingdom were $215.7 million, $197.0 million and $117.2 million, or 13.3%, 13.3% and 9.2% of total operating revenues for 
the years ended December 31, 2014, 2013 and 2012, respectively. No other foreign country comprised more than 10% of total operating revenues for each of these years. We had long-lived 
assets located in the United Kingdom of $1.7 billion, $1.8 billion and $1.7 billion, or 21.3%, 21.1% and 22.3% of total long-lived assets as of December 31, 2014, 2013 and 2012, 
respectively. No other foreign country comprised more than 10% of total long-lived assets as of each of December 31, 2014, 2013 and 2012. 

(x) Reclassifications  

Certain immaterial reclassifications to prior year amounts have been made to conform to the current year presentation. The Company has revised the presentation in its 2013 
consolidated balance sheet to properly reflect the impact of certain cash received prior to year-end as a reduction to accounts receivable, rather than as prepaid rent. The impact of this 
revision decreased the amounts previously reported in the 2013 balance sheet for accounts and other receivables and security deposits and prepaid rents by $58.9 million. In addition, during 
the years ended December 31, 2013 and 2012, $(1.8) million and $(1.1) million were reclassified from rental property operating and maintenance expense to change in fair value of 
contingent consideration, respectively. 

(y) Recent Accounting Pronouncements 

In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-8, Presentation of Financial Statements (Topic 205) and Property, 
Plant, and Equipment (Topic 360), Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which amends the requirements for reporting discontinued 
operations. Under ASU 2014-8, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a 
strategic shift that has (or will have) a major effect on an entity’s operations and financial results when the component or group of components meets the criteria to be classified as held for 
sale or when the component or group of components is disposed of by sale or other than by sale. Under the previous guidance, the Company's current year disposals and assets classified as 
held for sale would have qualified for discontinued operations presentation. However, under the new guidance, the actual and planned disposals do not represent a strategic shift that will 
have a major effect on operations and financial results. As a result, discontinued operations presentation is not provided for these actual and planned disposals. In addition, this ASU 
requires additional disclosures about both discontinued operations and the disposal of an individually significant component of an entity that does not qualify for discontinued operations 
presentation in the financial statements. As permitted by the standard, the Company has elected to early adopt the provisions of ASU 2014-8 as of January 1, 2014 and is applying the 
provisions prospectively.  

In May 2014, the FASB issued an update (ASU 2014-09) establishing ASC Topic 606, Revenue from Contracts with Customers.  ASU 2014-09 establishes a single comprehensive 
model for entities to use in accounting for revenue arising from contracts with customers and supersedes most of the existing revenue recognition guidance.  ASU 2014-09 requires an entity 
to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those
goods or services and also requires certain additional disclosures.  ASU 2014-09 is effective for interim and annual reporting periods in fiscal years that begin after December 15, 2016.  We
are currently evaluating the impact of the adoption of ASU 2014-09 on our consolidated financial statements. 

In June 2014, the FASB issued an update (ASU 2014-12) to ASC Topic 718, Compensation - Stock Compensation.  ASU 2014-12 requires an entity to treat performance targets that 
can be met after the requisite service period of a share based award has ended, as a performance condition that affects vesting.  ASU 2014-12 is effective for interim and annual reporting 
periods in fiscal years that begin after December 15, 2015.  We are currently evaluating the impact of the adoption of ASU 2014-12 on our consolidated financial statements.  

In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which provides guidance on the consolidation evaluation 
for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. In accordance with the guidance, all legal entities are subject to reevaluation 
under the revised consolidation model. The guidance is effective in the first quarter of 2016, and early adoption is permitted. We are currently evaluating the potential impact of the 
adoption of ASU 2015-02 on our consolidated financial statements.

MetCenter Business Park consists of three buildings at 8201 E. Riverside Drive and three buildings at 7401 E. Ben White Boulevard in the Austin metropolitan area. MetCenter 
Business Park is considered one property for our property count. 

Acquisition of a partially-built data center in Groningen, Netherlands for a purchase price of $3.9 million. We paid an additional $2.6 million in October 2013 upon completion of 
construction by the tenant, with the final payment of $1.4 million made in December 2013. 

(5) 

In connection with the acquisition, we assumed a $26.4 million secured mortgage loan.

Dispositions 

On April 7, 2014, the Operating Partnership sold 6 Braham Street to the tenant pursuant to a sale of the ownership interests in the Operating Partnership’s wholly owned subsidiary 

that owned the building for £25.0 million (or approximately $41.5 million based on the exchange rate as of April 7, 2014). The transaction after costs and various tenant prepayments 
resulted in net proceeds of approximately £22.6 million (or approximately $37.5 million based on the exchange rate as of April 7, 2014) and a net gain of approximately $15.9 million. The 
transaction includes substantially all of the assets of 6 Braham Street and we expect no further cash flows following the sale date.

December 31, 2014 and 2013 

The property was identified as held for sale in March 2014. 6 Braham Street was not a significant component of our United Kingdom portfolio nor does the sale of 6 Braham represent 

a significant shift in our strategy.  

We have identified certain non-core investment properties we intend to sell as part of our capital recycling strategy. Our capital recycling program is designed to identify non-strategic 
and underperforming assets that can be sold to generate proceeds that will support the funding of our core investment activity. We expect our capital recycling initiative will likewise have a 
meaningfully positive impact on overall return on invested capital. In addition, our capital recycling program does not represent a strategic shift, as we are not entirely exiting regions or 
property types. During this process, we are evaluating the carrying value of certain investment properties identified for potential sale to ensure the carrying value is recoverable in light of a 
potentially shorter holding period. As a result of our evaluation, during the year ended December 31, 2014, we recognized $126.5 million of impairment losses on five properties located in 
the Midwest, Northeast and West regions. The fair value of the five properties were primarily based on discounted cash flow analysis, and in certain cases, we supplemented the analysis by 
obtaining broker opinions of value. As of December 31, 2014, these properties do not meet the criteria to be classified as held for sale.  

As of December 31, 2014, the Company has taken the necessary actions to conclude that five properties to be disposed of as part of our capital recycling strategy met the criteria to be 

classified as held for sale. As of December 31, 2014, these five properties had an aggregate carrying value of $120.5 million within total assets and $5.8 million within total liabilities and 
are shown as assets held for sale and obligations associated with assets held for sale on the consolidated balance sheet. The five properties are not representative of a significant component 
of our portfolio, nor does the potential sales represent a significant shift in our strategy.

4. Investment in Unconsolidated Joint Ventures

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS- (Continued) 
December 31, 2014 and 2013 

Our investment in the 2001 Sixth Avenue joint venture included in our consolidated balance sheet exceeds our equity presented in the joint venture’s balance sheet since our purchase 

accounting adjustments are not pushed down to the joint venture. 

In March 2012, we entered into a joint venture with Savvis, Inc., a CenturyLink company. On June 26, 2012, this unconsolidated joint venture acquired a 164,000 square foot 
property in Hong Kong. The property is located at 33 Chun Choi Street in Hong Kong. As of December 31, 2014, we have contributed approximately $57.4 million to this joint venture. 

PREI ® Joint Venture

On September 27, 2013, we formed a joint venture with an investment fund managed by Prudential Real Estate Investors (PREI®). We contributed nine Powered Base Building® data 
centers valued at approximately $366.4 million plus 20% of $2.8 million of closing costs. The PREI®-managed fund contributed cash equal to their 80% interest in the joint venture assets at 
fair value and we retained a 20% interest. The joint venture is structured to provide a current annual preferred return from cash flow first to the PREI®-managed interest, then to our interest, 
after which a portion of any excess cash flows is shared by the partners based on their respective interests and the remaining portion is paid to us as a promote interest. We perform the day-
to-day accounting and property management functions for the joint venture and, as such, will earn a management fee. Although we are the managing member of the joint venture and 
manage the day-to-day activities, all significant decisions, including approval of annual budgets, require approval of the PREI-managed member. Thus, we concluded we do not own a 
controlling interest and will account for our interest in the joint venture as an equity method investment. 

The joint venture has arranged a $185.0 million five-year unsecured bank loan at LIBOR plus 180 basis points, representing a loan-to-value ratio of approximately 50%. Proceeds 
from the debt offset the contribution amounts required of the partners. The transaction generated approximately $328.6 million of net proceeds to us, comprised of our share of the initial 
draw-down on the bank loan in addition to the PREI® fund’s equity contribution, less our share of closing costs and accordingly we recognized a gain of approximately $115.6 million on 
the sale of the 80% interest in the nine properties during the year ended December 31, 2013. 

The operations of properties that we contributed to the joint venture are not recorded as discontinued operations because of our continuing involvement with these investment 
properties. Differences between the Company’s investment in the joint venture and the amount of the underlying equity in net assets of the joint venture are due to basis differences 
resulting from the Company’s equity investment recorded at its historical basis versus the fair value of the Company’s contributed interest in the joint venture. Our proportionate share of 
the earnings or losses related to this unconsolidated joint venture is reflected as equity in earnings of unconsolidated joint ventures on the accompanying consolidated income statements. 

On March 5, 2014, we contributed the 636 Pierce Street property, which we acquired in December 2013, to our unconsolidated joint venture with the PREI® fund that was formed in 

September 2013. The property was valued at approximately $40.4 million and subject to $26.1 million in debt, which the joint venture assumed. The PREI® fund contributed 
approximately $11.4 million in cash for their 80% share of the net asset value of $14.3 million. Subsequent to the closing, the joint venture refinanced the existing debt with $23.0 million 
drawn from the joint venture’s bank facility. Including the refinance costs, the PREI® fund contributed $17.5 million for the 636 Pierce Street property, bringing their contributed capital in 
the joint venture to $164.8 million. The transaction generated net proceeds of approximately $11.4 million and resulted in a $1.9 million gain.

Griffin Capital Essential Asset REIT, Inc. Joint Venture  

On September 9, 2014, we formed a joint venture with an affiliate of Griffin Capital Essential Asset REIT, Inc. (GCEAR). We contributed to the joint venture the property located at 

43915 Devin Shafron Drive (Building A) in Ashburn, Virginia, which is a Turn-Key Flex® data center property valued at approximately $185.5 million (excluding approximately $2.1 
million of closing costs). GCEAR contributed cash to the joint venture and will hold an 80% interest in the joint venture. We retained a 20% interest in the joint venture. The joint venture 
agreement provides for a current annual preferred return from cash flow first to GCEAR and then to us, after which a portion of any excess cash flows is shared by the partners based on 
their respective interests and the remaining portion is paid to us as a promote interest. We will perform the day-to-day accounting and property management functions for the joint venture 
and the property and, as such, will earn management fees. Although we are the managing member of the joint venture and manage the day-to-day activities, certain major decisions, 
including approval of annual budgets, require approval of the GCEAR member. Thus, we concluded we do not own a controlling interest and will account for our interest in the joint 
venture as an equity method investment.  

The joint venture arranged a $102.0 million five-year secured bank loan at LIBOR plus 225 basis points, representing a loan-to-value ratio of approximately 55%. The joint venture 

entered into an interest rate swap agreement to effectively fix the interest rate on approximately $51.0 million of borrowings under the loan through September 2019. Two one-year 
extensions of the maturity date are available under the loan agreement, which the joint venture may exercise if certain conditions are met. Proceeds from this loan offset the initial cash 
capital contribution amount required from GCEAR and was used to provide us with a special distribution on account of a portion of the contribution value of the property. The transaction 
generated approximately $167.5 million of net proceeds to us, comprised of our share of the initial draw-down on the bank loan in addition to GCEAR’s equity contribution, less our share 
of closing costs. Accordingly we recognized a gain of approximately $93.5 million on the sale of the 80% interest in the joint venture during the year ended December 31, 2014. 

Differences between the Company’s investment in the joint ventures and the amount of the underlying equity in net assets of the joint ventures result from the Company’s equity 

investment recorded at its historical basis versus the fair value of the Company’s contributed interest recorded at the joint venture level. Our proportionate share of the earnings or losses 
related to these unconsolidated joint ventures is reflected as equity in earnings of unconsolidated joint ventures on the accompanying consolidated income statements and reflects the 
amortization of such basis differences.  

We amortize the difference between the cost of our investment in the joint ventures and the book value of the underlying equity into income on a straight-line basis consistent with the 

lives of the underlying assets. The amortization of this difference was approximately $0.5 million and $0.1 million for the years ended December 31, 2014 and 2013, respectively. 

Sale of Investment 

On October 17, 2014, we closed on the sale of our investment in a developer of data centers in the Southwestern U.S. and Mexico, generating net proceeds of approximately $31.7 

million. We recognized a gain on sale of approximately $14.6 million in the fourth quarter of 2014. The original investment of $17.1 million was included in other assets on the 
consolidated balance sheet.

and 11830 Webb Chapel Road. Each of these loans is cross-collateralized by the six properties. These were repaid in full in September 2014. 

The respective borrower’s assets and credit are not available to satisfy the debts and other obligations of affiliates or any other person.

We have entered into interest rate swap agreements as a cash flow hedge for interest generated by the U.S. dollar and Singapore dollar tranches of the unsecured term loan. See

Global Revolving Credit Facility 

On August 15, 2013, the Operating Partnership refinanced its global revolving credit facility, increasing its total borrowing capacity to $2.0 billion from $1.8 billion. The global 
revolving credit facility has an accordion feature that would enable us to increase the borrowing capacity of the credit facility to $2.55 billion, subject to the receipt of lender commitments 
and other conditions precedent. The refinanced facility matures on November 3, 2017, with two six-month extension options available. The interest rate for borrowings under the expanded 
facility equals the applicable index plus a margin which is based on the credit ratings of our long-term debt and is currently 110 basis points. An annual facility fee on the total commitment 
amount of the facility, based on the credit ratings of our long-term debt, currently 20 basis points, is payable quarterly. Funds may be drawn in U.S., Canadian, Singapore, Australian and 
Hong Kong dollars, as well as Euro, British pound sterling, Swiss franc, Japanese yen and Mexican peso denominations. As of December 31, 2014, interest rates are based on 1-month 
LIBOR, 1-month GBP LIBOR, 1-month EURIBOR, 1-month BBR, 1-month HIBOR, 1-month JPY LIBOR, 1-month SIBOR and 1-month CDOR plus a margin of 1.10%. The facility also 
bore a base borrowing rate of 3.35% (USD) which is based on U.S. Prime Rate plus a margin of 0.10%. We have used and intend to use available borrowings under the global revolving 
credit facility to acquire additional properties, to fund development opportunities and for general working capital and other corporate purposes, including potentially for the repurchase, 
redemption or retirement of outstanding debt or equity securities. As of December 31, 2014, we have capitalized approximately $18.0 million of financing costs related to the global 
revolving credit facility. As of December 31, 2014, approximately $526.0 million was drawn under this facility and $9.3 million of letters of credit were issued, leaving approximately $1.4 
billion available for use.  

The global revolving credit facility contains various restrictive covenants, including limitations on our ability to incur additional indebtedness, make certain investments or merge 

with another company, and requirements to maintain financial coverage ratios, including with respect to unencumbered assets. In addition, the global revolving credit facility restricts 
Digital Realty Trust, Inc. from making distributions to its stockholders, or redeeming or otherwise repurchasing shares of its capital stock, after the occurrence and during the continuance 
of an event of default, except in limited circumstances including as necessary to enable Digital Realty Trust, Inc. to maintain its qualification as a REIT and to minimize the payment of 
income or excise tax. As of December 31, 2014, we were in compliance with all of such covenants.

Unsecured Term Loan 

On August 15, 2013, we refinanced the senior unsecured multi-currency term loan facility, increasing its total borrowing capacity to $1.0 billion from $750.0 million. Pursuant to the 
accordion feature, total commitments can be increased to $1.1 billion, subject to the receipt of lender commitments and other conditions precedent. The facility matures on April 16, 2017, 
with two six-month extension options available. Interest rates are based on our senior unsecured debt ratings and are currently 120 basis points over the applicable index for floating rate 
advances. Funds may be drawn in U.S, Singapore and Australian dollars, as well as Euro and British pound sterling denominations with the option to add Hong Kong dollars and Japanese 
yen upon an accordion exercise. Based on exchange rates in effect at December 31, 2014, the balance outstanding is approximately $1.0 billion. We have used borrowings under the term 
loan for acquisitions, repayment of indebtedness, development, working capital and general corporate purposes. The covenants under this loan are consistent with our global revolving 
credit facility and, as of December 31, 2014, we were in compliance with all of such covenants. As of December 31, 2014, we have capitalized approximately $8.4 million of financing 
costs related to the unsecured term loan. 

Unsecured Senior Notes 

Prudential Shelf Facility 

On January 20, 2010, the Operating Partnership closed the sale of $100.0 million aggregate principal amount of its senior unsecured term notes to Prudential Investment Management, 

Inc. and certain of its affiliates, or, collectively, Prudential, pursuant to a Note Purchase and Private Shelf Agreement, which we refer to as the Prudential shelf facility. The notes were 
issued in two series referred to as the series D and series E notes. The series D notes have a principal amount of $50.0 million, an interest-only rate of 4.57% per annum and a five-years 
maturity, and the series E notes have a principal amount of $50.0 million, an interest-only rate of 5.73% per annum and a seven-years maturity. On February 3, 2010, the Operating 
Partnership closed the sale of an additional $17.0 million aggregate principal amount of its senior unsecured term notes, which we refer to as the series F notes, to Prudential pursuant to the 
Prudential shelf facility. The series F notes have an interest-only rate of 4.50% per annum and a five-year maturity. We used the proceeds of the series D, series E and series F notes to fund 
acquisitions, to temporarily repay borrowings under our corporate revolving credit facility, to fund working capital and for general corporate purposes. The sale of the series A ($25.0 
million), series B ($33.0 million) and series C ($25.0 million) were completed in July 2008, November 2008 and January 2009, respectively. We may prepay the notes of any series, in 
whole or in part, at any time at a price equal to the principal amount and accrued interest of the notes being prepaid, plus a make-whole provision. On December 8, 2010, the Operating 
Partnership and Prudential entered into an amendment to the Note Purchase and Private Shelf Agreement, increasing the capacity of the Prudential shelf facility from $200.0 million to 
$250.0 million. Our ability to make additional issuances of notes under the Prudential shelf facility expired on July 24, 2011, with $50.0 million remaining unissued under the shelf facility. 
On July 25, 2011, we repaid the $25.0 million of 7.00% Series A unsecured notes under the Prudential shelf facility at maturity. On November 5, 2013, we repaid the $33.0 million of 
9.32% Series B unsecured notes under the Prudential shelf facility at maturity. As of December 31, 2014 and 2013, there was $142.0 million and $142.0 million of unsecured senior notes 
outstanding, respectively. 

On August 15, 2013, concurrent with the refinancing of the global revolving credit facility, the Operating Partnership and Digital Realty Trust, Inc. and the other subsidiary 

guarantors set forth therein entered into Amendment No.1to the Amended and Restated Note Purchase and Private Shelf Agreement with Prudential to conform the restrictive and financial 
covenants of the original Prudential shelf facility that apply to the outstanding Series B, C, D, E and F Notes under the Prudential shelf facility to those in the global revolving credit facility 
described above and, subject to the completion of specified conditions, to authorize the potential issuance and sale of up to $50.0 million of additional senior unsecured fixed-rate term 
notes. The Prudential shelf facility contains restrictive covenants that are identical to those in our global revolving credit facility.

Exchangeable Senior Debentures 

5.50% Exchangeable Senior Debentures due 2029 

On April 20, 2009, the Operating Partnership issued $266.4 million of its 5.50% exchangeable senior debentures due April 15, 2029 (the 2029 Debentures). Costs incurred to issue the 

2029 Debentures were approximately $7.8 million. These costs were amortized over a period of five years, which represented the estimated term of the 2029 Debentures, and are included 
in deferred financing costs, net in the condensed consolidated balance sheet. The 2029 Debentures were general unsecured senior obligations of the Operating Partnership, ranked equally in 
right of payment with all other senior unsecured indebtedness of the Operating Partnership and were fully and unconditionally guaranteed by Digital Realty Trust, Inc.  

Interest was payable on October 15 and April 15 of each year beginning October 15, 2009 until the maturity date of April 15, 2029. The 2029 Debentures bore interest at 5.50% per 

annum and were exchangeable for shares of Digital Realty Trust, Inc. common stock at an exchange rate that was initially 23.2558 shares per $1,000 principal amount of 2029 Debentures. 
The exchange rate on the 2029 Debentures was subject to adjustment for certain events, including, but not limited to, certain dividends on Digital Realty Trust, Inc. common stock in excess 
of $0.33 per share per quarter (the “reference dividend”). Effective December 11, 2013, the exchange rate had been adjusted to 25.5490 shares per $1,000 principal amount of 2029 
Debentures as a result of the aggregate dividends in excess of the reference dividend that Digital Realty Trust, Inc. declared and paid on its common stock beginning with the quarter ended 
September 30, 2013 and through the quarter ended December 31, 2013.  

On March 17, 2014, we commenced an offer to repurchase, at the option of each holder, any and all of the outstanding 2029 Debentures at a price equal to 100% of the principal 
amount, as required by the terms of the indenture governing the 2029 Debentures. The repurchase offer expired on April 11, 2014. No 2029 Debentures were repurchased pursuant to this 
offer. On March 17, 2014, we also distributed a Notice of Redemption to the holders of the 2029 Debentures that the Operating Partnership intended to redeem all of the outstanding 2029 
Debentures, pursuant to its option under the indenture governing the 2029 Debentures, on April 18, 2014, at a price equal to 100% of the principal amount, plus accrued and unpaid interest 
thereon up to the redemption date. In connection with the redemption, holders of the 2029 Debentures had the right to exchange their 2029 Debentures on or prior to April 16, 2014. The 
2029 Debentures not surrendered pursuant to the repurchase offer on or prior to April 11, 2014, or for exchange on or prior to April 16, 2014, were redeemed on April 18, 2014.  

In connection with the redemption, at the request of the holders that exercised their exchange right pursuant to the terms of the 2029 Debentures, we issued 6,734,938 restricted shares 
of Digital Realty Trust, Inc. common stock in exchange for approximately $261.2 million in aggregate principal amount of the 2029 Debentures based on the then-applicable exchange rate 
of 25.7880 shares per $1,000 principal amount of 2029 Debentures. On April 18, 2014, the Operating Partnership redeemed for cash approximately $5.2 million in aggregate principal 
amount of the 2029 Debentures pursuant to its option under the indenture governing the 2029 Debentures at a price equal to 100% of the principal amount plus accrued and unpaid interest 
thereon up to the redemption date.  

On July 11, 2014, we issued 134,974 restricted shares of Digital Realty Trust, Inc. common stock in exchange for approximately $5.2 million in aggregate principal amount of the 

2029 Debentures to certain previous holders of the 2029 Debentures. The holders had the right to exchange the 2029 Debentures for shares of Digital Realty Trust, Inc. common stock, but 
inadvertently failed to exercise such rights. As a result, the 2029 Debentures were redeemed by the Operating Partnership for cash. We agreed to issue the shares of the common stock to the 
holders in exchange for the redemption payment that they received in the original redemption, effectively putting such holders in the same place as if they had originally exercised their 
rights to exchange their 2029 Debentures for the shares of Digital Realty Trust, Inc. common stock.

Digital Realty Trust, Inc. has elected to be treated and believes that it has been organized and has operated in a manner that has enabled it to qualify as a REIT for federal income tax 
purposes. As a REIT, Digital Realty Trust, Inc. is generally not subject to corporate level federal income taxes on earnings distributed currently to its stockholders. Since inception, Digital 
Realty Trust, Inc. has distributed at least 100% of its taxable income annually and intends to do so for the tax year ending December 31, 2014. As such, no provision for federal income 
taxes has been included in the accompanying consolidated financial statements for the years ended December 31, 2014, 2013 and 2012. 

The Operating Partnership is a partnership and is not required to pay federal income tax. Instead, taxable income is allocated to its partners, who include such amounts on their federal 

income tax returns. As such, no provision for federal income taxes has been included in the Operating Partnership’s accompanying condensed consolidated financial statements. 

We have elected taxable REIT subsidiary (“TRS”) status for some of our consolidated subsidiaries. In general, a TRS may provide services that would otherwise be considered 
impermissible for REITs to provide and may hold assets that REITs cannot hold directly. Income taxes for TRS entities were accrued, as necessary, for the years ended December 31, 2014, 
2013 and 2012. 

For our TRS entities and foreign subsidiaries that are subject to U.S. federal, state and foreign income taxes, deferred tax assets and liabilities are established for temporary 

differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the temporary differences reverse. A 
valuation allowance for deferred tax assets is provided if we believe it is more likely than not that the deferred tax asset may not be realized, based on available evidence at the time the 
determination is made. An increase or decrease in the valuation allowance that results from the change in circumstances that causes a change in our judgment about the realizability of the 
related deferred tax asset is included in income. Deferred tax assets (net of valuation allowance) and liabilities for our TRS entities and foreign subsidiaries were accrued, as necessary, for 
the years ended December 31, 2014, 2013 and 2012. As of December 31, 2014, we had deferred tax liabilities (located in accounts payable and other accrued expenses in the consolidated 
balance sheet), net of deferred tax assets (located in other assets in the consolidated balance sheet), of approximately $137.9 million primarily related to our foreign properties. The majority 
of our net deferred tax liability relates to differences between tax basis and book basis of the assets acquired in the Sentrum Portfolio acquisition during 2012. The valuation allowance at 
December 31, 2014 and 2013 relates primarily to certain foreign jurisdiction net operating loss carryforwards that we do not expect to utilize, and deferred tax assets resulting from certain 
foreign real estate acquisition costs, which are not depreciated for tax purposes, but are deductible upon ultimate sale of the property. Given the indefinite holding period associated with 
these assets, realization of these deferred tax assets is not more-likely-than-not as of December 31, 2014 and 2013.

On June 29, 2011, Digital Realty Trust, Inc. entered into equity distribution agreements, which we refer to as the 2011 Equity Distribution Agreements, with each of Merrill Lynch, 
Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and Morgan Stanley & Co. LLC, or the Agents, 
under which it could issue and sell shares of its common stock having an aggregate offering price of up to $400.0 million from time to time through, at its discretion, any of the Agents as its 
sales agents. The sales of common stock made under the 2011 Equity Distribution Agreements will be made in “at the market” offerings as defined in Rule 415 of the Securities Act. To 
date, Digital Realty Trust, Inc. has generated net proceeds of approximately $342.7 million from the issuance of approximately 5.7 million common shares under the 2011 Equity 
Distribution Agreements at an average price of $60.35 per share after payment of approximately $3.5 million of commissions to the sales agents and before offering expenses. No sales 
were made under the program during the years ended December 31, 2014 and 2013. As of December 31, 2014, shares of common stock having an aggregate offering price of $53.8 million 
remained available for offer and sale under the program. 

(b) Redeemable Preferred Stock 

7.000% Series E Cumulative Redeemable Preferred Stock 

On September 15, 2011, Digital Realty Trust, Inc. issued 11,500,000 shares of its 7.000% series E cumulative redeemable preferred stock, or the series E preferred stock, for net 
proceeds of $277.2 million, after deducting underwriting discounts and commissions and offering expenses. Dividends are cumulative on the series E preferred stock from the date of 
original issuance in the amount of $1.750 per share each year, which is equivalent to 7.000% of the $25.00 liquidation preference per share. Dividends on the series E preferred stock are 
payable quarterly in arrears. The first dividend paid on the series E preferred stock on December 30, 2011 was a pro rata dividend from and including the original issue date to and including 
December 31, 2011 in the amount of $0.515278 per share. The series E preferred stock does not have a stated maturity date and is not subject to any sinking fund or mandatory redemption 
provisions. Upon liquidation, dissolution or winding up, the series E preferred stock will

redeemable and series G cumulative redeemable preferred stock. Digital Realty Trust, Inc. is not allowed to redeem the series E preferred stock before September 15, 2016, except in 
limited circumstances to preserve its status as a REIT and upon specified change of control transactions. On or after September 15, 2016, Digital Realty Trust, Inc. may, at its option, 
redeem the series E preferred stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends on such 
series E preferred stock up to but excluding the redemption date. Holders of the series E preferred stock generally have no voting rights except for limited voting rights if Digital Realty 
Trust, Inc. fails to pay dividends for six or more quarterly periods (whether or not consecutive) and in certain other circumstances. Upon the occurrence of specified changes of control, as a 
result of which neither Digital Realty Trust, Inc.’s common stock nor the common securities of the acquiring or surviving entity (or American Depository Receipts, or ADRs, representing 
such securities) is listed on the New York Stock Exchange, the NYSE Amex Equities or the NASDAQ Stock Market or listed or quoted on a successor exchange or quotation system, each 
holder of series E preferred stock will have the right (unless, prior to the change of control conversion date specified in the Articles Supplementary governing the series E preferred stock, 
Digital Realty Trust, Inc. has provided or provides notice of its election to redeem the series E preferred stock) to convert some or all of the series E preferred stock held by it into a number

• 

the quotient obtained by dividing (i) the sum of the $25.00 liquidation preference plus the amount of any accrued and unpaid dividends to, but not including, the change of

6.625% Series F Cumulative Redeemable Preferred Stock 

On April 5, 2012 and April 18, 2012, Digital Realty Trust, Inc. issued an aggregate of 7,300,000 shares of its 6.625% series F cumulative redeemable preferred stock, or the series F 

preferred stock, for net proceeds of $176.2 million, after deducting underwriting discounts and commissions and offering expenses. Dividends are cumulative on the series F preferred stock 
from the date of original issuance in the amount of $1.65625 per share each year, which is equivalent to 6.625% of the $25.00 liquidation preference per share. Dividends on the series F 
preferred stock are payable quarterly in arrears. The first dividend paid on the series F preferred stock on June 29, 2012 was a pro rata dividend from and including the original issue date to 
and including June 30, 2012 in the amount of $0.395660 per share. The series F preferred stock does not have a stated maturity date and is not subject to any sinking fund or mandatory 
redemption provisions. Upon liquidation, dissolution or winding up, the series F preferred stock will rank senior to Digital Realty Trust, Inc. common stock with respect to the payment of 
distributions and other amounts and rank on parity with Digital Realty Trust, Inc. series E cumulative redeemable and series G cumulative redeemable preferred stock. Digital Realty Trust, 
Inc. is not allowed to redeem the series F preferred stock before April 5, 2017, except in limited circumstances to preserve its status as a REIT. On or after April 5, 2017, Digital Realty 
Trust, Inc. may, at its option, redeem the series F preferred stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued

redeemable preferred stock with respect to the payment of distributions and other amounts. Digital Realty Trust, Inc. is not allowed to redeem the series G preferred stock before April 9, 
2018, except in limited circumstances to preserve its status as a REIT. On or after April 9, 2018, Digital Realty Trust, Inc. may, at its option, redeem the series G preferred stock, in whole 
or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends on such series G preferred stock up to but excluding the 
redemption date. Holders of the series G preferred stock generally have no voting rights except for limited voting rights if Digital Realty Trust, Inc. fails to pay dividends for six or more 
quarterly periods (whether or not consecutive) and in certain other circumstances. Upon the occurrence of specified changes of control, as a result of which neither Digital Realty Trust, 
Inc.’s common stock nor the common securities of the acquiring or surviving entity (or American Depositary Receipts representing such securities) is listed on the New York Stock

Limited partners have the right to require the Operating Partnership to redeem part or all of their common units for cash based on the fair market value of an equivalent number of 
shares of Digital Realty Trust, Inc. common stock at the time of redemption. Alternatively, Digital Realty Trust, Inc. may elect to acquire those common units in exchange for shares of 
Digital Realty Trust, Inc. common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary 
distributions and similar events. Pursuant to authoritative accounting guidance, Digital Realty Trust, Inc. evaluated whether it controls the actions or events necessary to issue the maximum 
number of shares that could be required to be delivered under the share settlement of the noncontrolling Operating Partnership common and incentive units. Based on the results of this 
analysis, we concluded that the common and incentive Operating Partnership units met the criteria to be classified within equity. 

The redemption value of the noncontrolling Operating Partnership common units and the vested incentive units was approximately $179.0 million and $124.1 million based on the 

closing market price of Digital Realty Trust, Inc. common stock on December 31, 2014 and 2013, respectively.

Trust, Inc. (the General Partner) in conjunction with the General Partner’s issuance of an equivalent number of shares of its 7.000% series E cumulative redeemable preferred stock, or the

series F preferred units will rank senior to the common units with respect to the payment of distributions and other amounts and rank on parity with the Operating Partnership’s series E and 
series G preferred units. Except in connection with specified change of control transactions of the General Partner, the series F preferred units are not convertible into or exchangeable for 
any other property or securities of the Operating Partnership. 

5.875% Series G Cumulative Redeemable Preferred Units 

On April 9, 2013, the Operating Partnership issued a total of 10,000,000 of its 5.875% series G cumulative redeemable preferred units, or series G preferred units, to the General 
Partner in conjunction with the General Partner’s issuance of an equivalent number of shares of its 5.875% series G cumulative redeemable preferred stock, or the series G preferred stock. 
Distributions are cumulative on the series G preferred units from the date of original issuance in the amount of $1.46875 per unit each year, which is equivalent to 5.875% of the $25.00 
liquidation preference per unit. Distributions on the series G preferred units are payable quarterly in arrears. The first distribution paid on the series G preferred units on June 28, 2013 was a 
pro rata distribution from and including the original issue date to and including June 30, 2013 in the amount of $0.334550 per unit. The series G preferred units do not have a stated maturity 
date and are not subject to any sinking fund. The Operating Partnership is required to redeem the series G preferred units in the event that the General Partner redeems the series G preferred 
stock. The General Partner is not allowed to redeem the series G preferred stock prior to April 9, 2018 except in limited circumstances to preserve the General Partner’s status as a REIT. 
On or after April 9, 2018, the General Partner may, at its option, redeem the series G preferred stock, in whole or in part, at any time or from time to time, for cash at a redemption price of 
$25.00 per share, plus all accrued and unpaid dividends on such series G preferred stock up to but excluding the redemption date. Upon liquidation, dissolution or winding up, the series G 
preferred units will rank senior to the Operating Partnership’s common units with respect to the payment of distributions and other amounts and rank on parity with the Operating 
Partnership’s series E and series F preferred units. Except in connection with specified change of control transactions of the General Partner, the series G preferred units are not convertible 
into or exchangeable for any other property or securities of the Operating Partnership. 

7.375% Series H Cumulative Redeemable Preferred Units  

On March 26, 2014 and April 7, 2014, the Operating Partnership issued in the aggregate a total of 14,600,000 of its 7.375% series H cumulative redeemable preferred units, or series 
H preferred units, to Digital Realty Trust, Inc. (the General Partner) in conjunction with the General Partner’s issuance of an equivalent number of shares of its 7.375% series H cumulative 
redeemable preferred stock, or the series H preferred stock. Distributions are cumulative on the series H preferred units from the date of original issuance in the amount of $1.84375 per unit 
each year, which is equivalent to 7.375% of the $25.00 liquidation preference per unit. Distributions on the series H preferred units are payable quarterly in arrears. The first distribution 
payable on the series H preferred units on June 30, 2014 was a pro rata distribution from and including the original issue date to and including June 30, 2014 in the amount of $0.48655 per 
unit. The series H preferred units do not have a stated maturity date and are not subject to any sinking fund. The Operating Partnership is required to redeem the series H preferred units in 
the event that the General Partner redeems the series H preferred stock. The General Partner is not allowed to redeem the series H preferred stock prior to March 26, 2019 except in limited 
circumstances to preserve the General Partner’s status as a REIT. On or after March 26, 2019, the General Partner may, at its option, redeem the series H preferred stock, in whole or in 
part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends on such series H preferred stock up to but excluding the 
redemption date. Upon liquidation, dissolution or winding up, the series H preferred units will rank senior to the Operating Partnership’s common units with respect to the payment of 
distributions and other amounts and rank on parity with the Operating Partnership’s series E cumulative redeemable preferred units, series F cumulative redeemable preferred units and 
series G cumulative redeemable preferred units. Except in connection with specified change of control transactions of the General Partner, the series H preferred units are not convertible 
into or exchangeable for any other property or securities of the Operating Partnership.  

(b) Allocations of Net Income and Net Losses to Partners 

Except for special allocations to holders of profits interest units described below in note 13(a) under the heading “Incentive Plan-Long-Term Incentive Units,” the Operating 

Partnership’s net income will generally be allocated to the General Partner to the extent of the accrued preferred return on its preferred units, and then to the General Partner and the 
Operating Partnership’s limited

partners in accordance with the respective percentage interests in the common units issued by the Operating Partnership. Net loss will generally be allocated to the General Partner and the 
Operating Partnership’s limited partners in accordance with the respective common percentage interests in the Operating Partnership until the limited partner’s capital is reduced to zero and 
any remaining net loss would be allocated to the General Partner. However, in some cases, losses may be disproportionately allocated to partners who have guaranteed our debt. The 
allocations described above are subject to special allocations relating to depreciation deductions and to compliance with the provisions of Sections 704(b) and 704(c) of the Code, and the 
associated Treasury Regulations. 

(c) Partnership Units 

Limited partners have the right to require the Operating Partnership to redeem part or all of their common units for cash based on the fair market value of an equivalent number of 

shares of the General Partner’s common stock at the time of redemption. Alternatively, the General Partner may elect to acquire those common units in exchange for shares of the General 
Partner’s common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar 
events. Pursuant to authoritative accounting guidance, the Operating Partnership evaluated whether it controls the actions or events necessary to issue the maximum number of shares that 
could be required to be delivered under the share settlement of the limited partners’ common units and the vested incentive units. Based on the results of this analysis, the Operating 
Partnership concluded that the common and vested incentive Operating Partnership units met the criteria to be classified within capital. 

The redemption value of the limited partners’ common units and the vested incentive units was approximately $179.0 million and $124.1 million based on the closing market price of 

Digital Realty Trust, Inc.’s common stock on December 31, 2014 and 2013, respectively. 

(d) Distributions 

All distributions on our units are at the discretion of Digital Realty Trust, Inc.’s board of directors. We have declared and paid the following distributions on our common and 

preferred units for the years ended December 31, 2014, 2013 and 2012 (in thousands):

Our Amended and Restated 2004 Incentive Award Plan (as defined below) previously provided for the grant of incentive awards to employees, directors and consultants. Awards 
issuable under the Amended and Restated 2004 Incentive Award Plan included stock options, restricted stock, dividend equivalents, stock appreciation rights, long-term incentive units, 
cash performance bonuses and other incentive awards. Only employees were eligible to receive incentive stock options under the Amended and Restated 2004 Incentive Award Plan. 
Initially, we had reserved a total of 4,474,102 shares of common stock for issuance pursuant to the Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2004 
Incentive Award Plan (the 2004 Incentive Award Plan), subject to certain adjustments set forth in the 2004 Incentive Award Plan. On May 2, 2007, Digital Realty Trust, Inc.’s stockholders 
approved the First Amended and Restated Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2004 Incentive Award Plan (as amended, the Amended and 
Restated 2004 Incentive Award Plan). The Amended and Restated 2004 Incentive Award Plan increased the aggregate number of shares of stock which could have been issued or 
transferred under the plan by 5,000,000 shares to a total of 9,474,102 shares, and provided that the maximum number of shares of stock with respect to awards granted to any one 
participant during a calendar year was 1,500,000 shares and the maximum amount that could have been paid in cash during any calendar year with respect to any performance-based award 
not denominated in stock or otherwise for which the foregoing limitation would not be an effective limitation for purposes of Section 162(m) of the Code was $10.0 million.  

On April 28, 2014, Digital Realty Trust, Inc. held its 2014 Annual Meeting of Stockholders, or the 2014 Annual Meeting, at which the Company’s stockholders approved the Digital 

Realty Trust, Inc., Digital Services, Inc., and Digital Realty Trust, L.P. 2014 Incentive Award Plan (as amended, the 2014 Incentive Award Plan), which had been previously adopted by the 
Board of Directors and recommended to the stockholders for approval by the Company’s Board of Directors. The 2014 Incentive Award Plan became effective and replaced the Amended 
and Restated 2004 Incentive Award Plan as of the date of such

stockholder approval. The material features of the 2014 Incentive Award Plan are described in our definitive Proxy Statement filed on March 19, 2014 in connection with the 2014 Annual 
Meeting. 

As of December 31, 2014, 5,388,485 shares of common stock or awards convertible into or exchangeable for common stock remained available for future issuance under the 2014 
Incentive Award Plan. Each long-term incentive unit and Class D Unit issued under the 2014 Incentive Award Plan counts as one share of common stock for purposes of calculating the 
limit on shares that may be issued under the 2014 Incentive Award Plan and the individual award limits set forth therein. 

(a) Long-Term Incentive Units 

Long-term incentive units, which are also referred to as profits interest units, may be issued to eligible participants for the performance of services to or for the benefit of the 

Operating Partnership. Long-term incentive units (other than Class D Units), whether vested or not, will receive the same quarterly per unit distributions as Operating Partnership common 
units, which equal per share distributions on Digital Realty Trust, Inc. common stock. Initially, long-term incentive units do not have full parity with common units with respect to 
liquidating distributions. If such parity is reached, vested long-term incentive units may be converted into an equal number of common units of the Operating Partnership at any time, and 
thereafter enjoy all the rights of common units of the Operating Partnership, including redemption rights.  

In order to achieve full parity with common units, long-term incentive units must be fully vested and the holder’s capital account balance in respect of such long-term incentive units 

must be equal to the capital account balance of a holder of an equivalent number of common units. The capital account balance attributable to each common unit is generally expected to be 
the same, in part because of the amount credited to a partner’s capital account upon the partner’s contribution of property to the Operating Partnership, and in part because the partnership 
agreement provides, in most cases, that allocations of income, gain, loss and deduction (which will adjust the partner’s capital accounts) are to be made to the common units on a 
proportionate basis. As a result, with respect to a number of long-term incentive units, it is possible to determine the capital account balance of an equivalent number of common units by 
multiplying the number of long-term incentive units by the capital account balance with respect to a common unit.  

A partner’s initial capital account balance is equal to the amount the partner paid (or contributed to the Operating Partnership) for the partner’s units and is subject to subsequent 
adjustments, including with respect to the partner’s share of income, gain or loss of the Operating Partnership. Because a holder of long-term incentive units generally will not pay for the 
long-term incentive units, the initial capital account balance attributable to such long-term incentive units will be zero. However, the Operating Partnership is required to allocate income, 
gain, loss and deduction to the partner’s capital accounts in accordance with the terms of the partnership agreement, subject to applicable Treasury Regulations. The partnership agreement 
provides that holders of long-term incentive units will receive special allocations of gain in the event of a sale or “hypothetical sale” of assets of the Operating Partnership prior to the 
allocation of gain to Digital Realty Trust, Inc. or other limited partners with respect to their common units. The amount of such allocation will, to the extent of any such gain, be equal to the 
difference between the capital account balance of a holder of long-term incentive units attributable to such units and the capital account balance attributable to an equivalent number of 
common units. If and when such gain allocation is fully made, a holder of long-term incentive units will have achieved full parity with holders of common units. To the extent that, upon an 
actual sale or a “hypothetical sale” of the Operating Partnership’s assets as described above, there is not sufficient gain to allocate to a holder’s capital account with respect to long-term 
incentive units, or if such sale or “hypothetical sale” does not occur, such units will not achieve parity with common units.  

The term “hypothetical sale” refers to circumstances that are not actual sales of the Operating Partnership’s assets but that require certain adjustments to the value of the Operating 
Partnership’s assets and the partners’ capital account balances. Specifically, the partnership agreement provides that, from time to time, in accordance with applicable Treasury Regulations, 
the Operating Partnership will adjust the value of its assets to equal their respective fair market values, and adjust the partners’ capital accounts, in accordance with the terms of the 
partnership agreement, as if the Operating Partnership sold its assets for an amount equal to their value. Times for making such adjustments generally include the liquidation of the 
Operating Partnership, the acquisition of an additional interest in the Operating Partnership by a new or existing partner in exchange for more than a de minimis capital contribution, the 
distribution by the Operating Partnership to a partner of more than a de minimis amount of partnership property as consideration for an interest in the Operating Partnership, in connection 
with the grant of an interest in the Operating Partnership (other than a de minimis interest) as consideration for the performance of services to or for the

benefit of the Operating Partnership (including the grant of a long-term incentive unit), and at such other times as may be desirable or required to comply with the Treasury Regulations.

During the year ended December 31, 2013, certain employees were granted an aggregate of 95,316 long-term incentive units, which, in addition to a service condition, were subject to 
a performance condition that impacted the number of units which ultimately vested. The performance condition was based upon our achievement of the 2013 Core Funds From Operations, 
or CFFO, per share targets. Based on our 2013 CFFO per diluted share and unit, 75,105 of the 2013 long-term incentive units, net of forfeitures, satisfied the performance condition. The 
grant date fair values, which equal the market price of Digital Realty Trust, Inc. common stock on the grant date, are being expensed on a straight-line basis for service awards over four 
years, the current vesting period of the long-term incentive units. We expense the fair value of awards that contain a performance condition using an accelerated method with each vesting 
tranche valued as a separate award. 

The expense recorded for the years ended December 31, 2014, 2013 and 2012 related to long-term incentive units was approximately $12.6 million, $8.9 million and $9.0 million, 

respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $1.7 million, 
$1.6 million and $1.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. Unearned compensation representing the unvested portion of the long-term incentive 
units totaled $9.3 million and $12.9 million as of December 31, 2014 and 2013, respectively. We expect to recognize this unearned compensation over the next 2.0 years on a weighted 
average basis. 

(b) 2014 Market Performance-Based Awards  

On February 11, 2014, the Compensation Committee of the Board of Directors of the Company approved the grant of market performance-based Class D Units of the Operating 
Partnership and market performance-based restricted stock units, or RSUs, covering shares of the Company’s common stock (collectively, the “awards”), under the Amended and Restated 
2004 Incentive Award Plan to officers and employees of the Company. In March 2014 and April 2014, the Compensation Committee of the Board of Directors of the Company approved 
the grant of additional market performance-based Class D Units of the Operating Partnership to certain officers of the Company, under the Amended and Restated 2004 Incentive Award 
Plan and 2014 Incentive Plan, respectively.  

The awards, which were determined to contain a market condition, utilize total shareholder return, or TSR, over a three-year measurement period as the market performance metric. 

Awards will vest based on the Company’s TSR relative to the MSCI US REIT Index, or RMS, over a three-year market performance period, or the Market Performance Period, 
commencing in January 2014 (or, if earlier, ending on the date on which a change in control of the Company occurs), subject to continued services. Vesting with respect to the market 
condition is measured based on the difference between the Company’s TSR percentage and the TSR percentage of the RMS, or the RMS Relative Market Performance. In the event that the 
RMS Relative Market Performance during the Market Performance Period is achieved at the “threshold,” “target” or “high” level as set forth below, the awards will become vested as to the 
market condition with respect to the percentage of Class D units or RSUs, as applicable, set forth below:

If the RMS Relative Market Performance falls between the levels specified above, the percentage of the award that will vest with respect to the market condition will be determined 

using straight-line linear interpolation between such levels.  

Following the completion of the Market Performance Period, awards that have satisfied the market condition, if any, will vest 50% on February 27, 2017 and 50% on February 27, 

2018, subject to continued employment through each applicable vesting date.  

Service-based vesting will be accelerated, in full or on a pro rata basis, in the event of a change in control, termination of employment by the Company without cause, or termination 

of employment by the award recipient for good reason, death, disability or retirement, in any case prior to the completion of the Market Performance Period.. However, vesting with respect 
to the market condition will continue to be measured based on RMS Relative Market Performance during the three-year Market Performance Period (or, in the case of a change in control, 
shortened Market Performance Period).  

The fair value of the 2014 grant of awards was measured using a Monte Carlo simulation to estimate the probability of the market vesting condition being satisfied. The Company’s 

achievement of the market vesting condition is contingent on its TSR over a three-year market performance period, relative to the total shareholder return of the RMS. The Monte Carlo 
simulation is a probabilistic technique based on the underlying theory of the Black-Scholes formula, which was run for 100,000 trials to determine the fair value of the awards. For each 
trial, the payoff to an award is calculated at the settlement date and is then discounted to the grant date at a risk-free interest rate. The total expected value of the awards on the grant date 
was determined by multiplying the average value per award over all trials by the number of awards granted. Assumptions used in the valuation include expected stock price volatility of 33 
percent and a risk-free interest rate of 0.67 percent. The valuation was performed in a risk-neutral framework, so no assumption was made with respect to an equity risk premium.  

As of December 31, 2014, 664,316 Class D Units and 248,026 market performance-based RSUs had been awarded to our executive officers and other employees. The number of units 
granted reflects the maximum number of Class D units or market performance-based RSUs, as applicable, which will become vested assuming the achievement of the highest level of RMS 
Relative Market Performance under the awards and, in the case of the Class D units, also includes dividend equivalent units. The fair value of these awards of approximately $17.4 million 
will be recognized as compensation expense on a straight-line basis over the expected service period of approximately four years. The unearned compensation as of December 31, 2014 was 
$9.5 million, net of cancellations. As of December 31, 2014, none of the above awards had vested. We recognized compensation expense related to these awards of approximately $3.0 
million in the year ended December 31, 2014. We capitalized amounts relating to compensation expense of employees directly engaged in construction and leasing activities of 
approximately $1.4 million for the year ended December 31, 2014. If the market condition is not met at the end of the performance period, the unamortized amount will be recognized as an 
expense at that time.

All restricted stock granted in 2014 is subject only to a service condition.

The grant date fair values, which equal the market price of Digital Realty Trust, Inc. common stock on the grant date, are being expensed on a straight-line basis for service awards 
over the vesting period of the restricted stock, which ranges from three to four years. We expense the fair value of awards that contain a performance condition using an accelerated method 
with each vesting tranche valued as a separate award.  

During the year ended December 31, 2013, certain employees were granted an aggregate of 69,995 shares of restricted stock, which, in addition to a service condition, were subject to 

a performance condition that impacted the number of shares which ultimately vested. The performance condition was based upon our achievement of the 2013 CFFO per share targets. 
Upon evaluating the results of the performance condition, the final number of shares was determined and such shares vest based on satisfaction of the service conditions. Based on our 2013 
CFFO per diluted share and unit, 50,805 shares of the 2013 restricted stock awards (net of forfeitures) satisfied the performance condition.

December 31, 2014 and 2013 

 The expense recorded for the years ended December 31, 2014, 2013 and 2012 related to grants of restricted stock was approximately $2.5 million, $2.7 million and $2.9 million, 
respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $2.7 million, 
$2.5 million and $2.1 million for the years ended December 31, 2014, 2013 and 2012, respectively. Unearned compensation representing the unvested portion of the restricted stock totaled 
$10.4 million and $8.7 million as of December 31, 2014 and 2013, respectively. We expect to recognize this unearned compensation over the next 2.5 years on a weighted average basis. 

(e) 401(k) Plan 

We have a 401(k) plan whereby our employees may contribute a portion of their compensation to their respective retirement accounts, in an amount not to exceed the maximum 

allowed under the Code. The 401(k) Plan complies with Internal Revenue Service requirements as a 401(k) Safe Harbor Plan whereby discretionary contributions made by us are 100% 
vested. The aggregate cost of our contributions to the 401(k) Plan was approximately $2.8 million, $2.4 million, and $2.0 million for the years ended December 31, 2014, 2013 and 2012, 
respectively. 

14. Derivative Instruments 

Currently, we use interest rate swaps to manage our interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques including 

discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses 
observable market-based inputs, including interest rate curves. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future 
fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest 
rates (forward curves) derived from observable market interest rate curves. 

To comply with the provisions of fair value accounting guidance, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the 

respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have 
considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. 

Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated 

with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. However, as of December 31, 2014, 
we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation 
adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair 
value hierarchy. We do not have any fair value measurements on a recurring basis using significant unobservable inputs (Level 3) as of December 31, 2014 or December 31, 2013. 

Cash Flow Hedges of Interest Rate Risk 

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements related to US LIBOR, GBP LIBOR and 
EURIBOR based mortgage loans as well as the U.S. LIBOR and SGD-SOR based tranches of the unsecured term loan. To accomplish this objective, we primarily use interest rate swaps as 
part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for 
making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. 

We record all our interest rate swaps on the consolidated balance sheet at fair value. In determining the fair value of our interest rate swaps, we consider the credit risk of our 
counterparties. These counterparties are generally larger financial institutions engaged in providing a variety of financial services. These institutions generally face similar risks regarding 
adverse changes in market and economic conditions, including, but not limited to, fluctuations in interest rates, exchange rates, equity and commodity prices and credit spreads. The current 
and pervasive disruptions in the financial markets have heightened the risks to these institutions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS- (Continued) 
December 31, 2014 and 2013 

Our agreements with some of our derivative counterparties provide that (1) we could be declared in default on our derivative obligations if repayment of any of our indebtedness over 

$75.0 million is accelerated by the lender due to our default on the indebtedness and (2) we could be declared in default on a certain derivative obligation if we default on any of our 
indebtedness, including a default where repayment of underlying indebtedness has not been accelerated by the lender. 

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is 

subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2014, such derivatives were used to hedge the variable cash flows 
associated with existing variable-rate debt. The fair value of these derivatives was $(2.4) million and $0.1 million at December 31, 2014 and December 31, 2013 respectively. The 
ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the year ended December 31, 2014, we recognized an increase to earnings of 
approximately $0.8 million related to the ineffective portion of our forward-starting swap. During the years ended December 31, 2013 and 2012, there were no ineffective portions to our 
interest rate swaps. 

Amounts reported in accumulated other comprehensive loss related to interest rate swaps will be reclassified to interest expense as interest payments are made on our debt. As of 

December 31, 2014, we estimate that an additional $2.7 million will be reclassified as an increase to interest expense during the year ending December 31, 2015, when the hedged 
forecasted transactions impact earnings. 

As of December 31, 2014 and December 31, 2013, we had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk (in

2014 and $0.79 to 1.00 SGD as of December 31, 2013. 

In January 2014, we entered into a forward-starting five-year swap contract to protect the Company against adverse fluctuations in interest rates by reducing its exposure to 
variability in cash flows relating to interest payments on a forecasted issuance of debt. The accrual period of the swap contract was designed to match the tenor of the planned debt 
issuance. In the fourth quarter of 2014, changes in the forecasted transaction resulted in the discontinuation of cash flow hedge accounting. As such, changes in the fair value of the 
forward starting swap were recognized in earnings, within the other income (expense) line item.  During 2014 the total net gain recognized on the forward starting swap was 
approximately $0.8 million, and on January 13, 2015, we cash settled the forward starting swap for approximately $5.7 million, including accrued interest.

15. Fair Value of Instruments 

We disclose fair value information about all financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practicable to estimate fair value. 

Current accounting guidance requires the Company to disclose fair value information about all financial instruments, whether or not recognized in the balance sheets, for which it is 
practicable to estimate fair value. 

The Company’s disclosures of estimated fair value of financial instruments at December 31, 2014 and December 31, 2013 were determined using available market information and 

appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different market assumptions or estimation 
methods may have a material effect on the estimated fair value amounts. 

The carrying amounts for cash and cash equivalents, restricted cash, accounts and other receivables, accounts payable and other accrued liabilities, accrued dividends and 

distributions, security deposits and prepaid rents approximate fair value because of the short-term nature of these instruments. As described in note 14, the interest rate swaps are recorded at 
fair value.  

We calculate the fair value of our mortgage loans, unsecured term loan, unsecured senior notes and exchangeable senior debentures based on currently available market rates assuming 

the loans are outstanding through maturity and considering the collateral and other loan terms. In determining the current market rate for fixed rate debt, a market spread is added to the 
quoted yields on federal government treasury securities with similar maturity dates to our debt. The carrying value of our global revolving credit facility approximates fair value, due to the 
variability of interest rates. 

As of December 31, 2014 and December 31, 2013, the aggregate estimated fair value and carrying value of our global revolving credit facility, unsecured term loan, unsecured senior 

notes, exchangeable senior debentures and mortgage loans were as follows (in thousands):

The carrying value of our global revolving credit facility approximates estimated fair value, due to the variability of interest rates and the stability of our credit rating.

The carrying value of our unsecured term loan approximates estimated fair value, due to the variability of interest rates and the stability of our credit rating.

Valuations for our unsecured senior notes and mortgage loans are determined based on the expected future payments discounted at risk-adjusted rates. The 2015 Notes, 2020 
Notes, 2021 Notes, 2022 Notes, 2023 Notes and 2025 Notes and 2029 Debentures are valued based on quoted market prices. 

The carrying value of the 2015 Notes, 2020 Notes, 2021 Notes, 2022 Notes, 2023 Notes and 2025 Notes are net of discount of $15.6 million and $15.0 million in the aggregate as

17. Related Party Transactions  

In December 2006, we entered into 10 leases with tel(x) pursuant to which tel(x) provides enhanced meet-me-room services to our customers. The initial terms of these leases expire 

in 2026, and tel(x) has options to extend them through 2046. tel(x) was acquired by GI Partners Fund II, LLP in November 2006, which, collectively with GI Partners Side Fund II, L.P., 
owned the majority of the outstanding stock of tel(x). Richard Magnuson, our former director and Chairman who served until our 2012 Annual Meeting of Stockholders, or the Annual 
Meeting, is the chief executive officer of the advisor to GI Partners Fund II, LLP and GI Partners Side Fund II, L.P. During the year ended December 31, 2011, GI Partners Fund II, LLP 
and GI Partners Side Fund II, L.P completed the sale of tel(x) to an unrelated third party. Our consolidated statements of operations include rental revenues of approximately $51.6 million, 
$48.6 million and $45.7 million from tel(x) for the years ended December 31, 2014, 2013 and 2012, respectively, from leases entered into before tel(x) was sold to an unrelated third party. 
In connection with the lease agreements, we entered into an operating agreement with tel(x), effective as of December 1, 2006, with respect to joint sales and marketing efforts, designation 
of representatives to manage the national relationship between us and tel(x) and future meet-me-room facilities. As of December 31, 2014 and 2013, tel(x) leased from us 341,202 square 
feet under 55 lease agreements; all but 14 leases for 86,888 square feet were entered into prior to the sale of tel(x) to an unrelated third party in September 2011. 

We also entered into an agreement with tel(x), effective as of December 1, 2006, with respect to percentage rent arising out of potential future lease agreements for rentable space in 

buildings covered by the meet-me-room lease agreements. Percentage rent earned during the years ended December 31, 2014, 2013 and 2012 amounted to approximately $7.1 million, $6.0 
million and $4.8 million, respectively. In addition, in connection with the lease agreements, we entered into a management agreement with tel(x), effective as of December 1, 2007, 
pursuant to which tel(x) agreed to provide us with certain management services in exchange for a management fee of one percent of rents actually collected by tel(x). 

Prior to the 2012 Annual Meeting, we had entered into 9 leases with SoftLayer, all of which are in place as of December 31, 2013. The initial terms of these leases expire from 2013 
to 2025, and SoftLayer has options to extend them from 2018 through 2035. On August 3, 2010, GI Partners Fund III, L.P. acquired a controlling interest in SoftLayer. Richard Magnuson, 
our former director and Chairman who served until our Annual Meeting, is also a manager of the general partner to GI Partners Fund III, L.P. Our consolidated statements of operations 
include rental revenues of approximately $51.8 million, $53.9 million and $48.3 million from SoftLayer for the years ended December 31, 2014, 2013 and 2012, respectively, from

leases entered into before Mr. Magnuson’s term as a member of our Board of Directors and our Chairman ended. In July 2013, SoftLayer was acquired by IBM. 

Mr. Magnuson did not stand for re-election to our Board of Directors at our Annual Meeting. His term as a member of our Board of Directors and our Chairman ended effective 

April 23, 2012, the date of the Annual Meeting. 

18. Commitments and Contingencies 

(a) Operating Leases 

We have a ground lease obligation on 2010 East Centennial Circle that expires in 2082. After February 2036, rent for the remaining term of the 2010 East Centennial Circle ground 

lease will be determined based on a fair market value appraisal of the property and, as result, rent after February 2036 is excluded from the minimum commitment information below. 

We have ground leases on Paul van Vlissingenstraat 16that expires in 2054, Chemin de l’Epinglier 2that expires in 2074, Clonshaugh Industrial Estate I and II that expires in 2981, 

Manchester Technopark that expires in 2125, 29A International Business Park that expires in 2038, Gyroscoopweg 2E-2F, which has a continuous ground lease and will be adjusted on 
January 1, 2042, and Naritaweg 52, which has a continuous ground lease. In late 2011, we executed a lease for a new location for our headquarters, which began in May 2012, with a lease 
term of 12 years with an option to extend the lease for an additional five years. We also have operating leases at 111 8th Avenue (2nd and 6th floors), 8100 Boone Boulevard, 111 8th Avenue 
(3rd and 7th floors) and 410 Commerce Boulevard, which expire in June 2024, September 2017, February 2022 and December 2026, respectively. The lease at 111 8th Avenue (2ndand 6th 
floors) has an option to extend the lease until June 2034 and the lease at 111 8th Avenue (3rd and 7th floors) has an option to extend the lease until February 2032. The leases at 8100 Boone 
Boulevard and 410 Commerce Boulevard have no extension options. 

We have a fully prepaid ground lease on 2055 E. Technology Circle that expires in 2083. We have a fully prepaid ground lease on Cateringweg 5 that expires in 2059. The ground 

lease at Naritaweg 52 has been prepaid through December 2036. 

Rental expense for these leases was approximately $16.2 million, $23.1 million, and $10.2 million for the years ended December 31, 2014, 2013 and 2012 respectively. In 2013, a 
non-cash $10.0 million straight-line rent expense adjustment was recorded in rental property operating and maintenance expenses related to a lease amendment executed in September 2010, 
$7.5 million of this amount related to prior years. This adjustment was deemed to be immaterial to both the current year and prior year financial statements taken as a whole. 

The minimum commitment under these leases, excluding the fully prepaid ground leases, as of December 31, 2014 was as follows (in thousands):

As part of the 29A International Business Park asset acquisition in 2010, the seller could earn additional consideration based on future net operating income growth in excess of certain 
performance targets, as defined in the agreements for the acquisition. As of December 31, 2014, certain leases executed subsequent to purchase have caused an amount to become probable 
of payment and therefore approximately $12.6 million has been accrued in accounts payable and accrued liabilities and capitalized to buildings and improvements in the consolidated 
balance sheet as of December 31, 2014. The maximum amount that could be earned by the seller is $50.0 million SGD (or approximately $37.7 million based on the exchange rate as of 
December 31, 2014). The earnout contingency expires in November 2020.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS- (Continued) 
December 31, 2014 and 2013 

One of the tenants at our Convergence Business Park property has an option to expand as part of their lease agreement, which expires in April 2017. As part of this option, 

development activities were not permitted on specifically identified expansion space within the property until April 2014. From April 2014 through April 2017, the tenant has the right of 
first refusal on any third party’s bona fide offer to buy the adjacent land. If the tenant exercises their option, we may either construct and lease to the tenant an additional shell building on 
the expansion space at a stipulated rate of return on cost or sell the existing building and the expansion space to the tenant for a price of approximately $24.0 million and $225,000 per 
square acre, respectively, plus additional adjustments as provided in the lease. 

As part of the acquisition of the Sentrum Portfolio, the seller could earn additional consideration based on future net returns on vacant space to be developed, but not currently leased, 
as defined in the purchase agreement for the acquisition. The initial estimate of fair value of the contingent consideration liability was approximately £56.5 million (or approximately $87.6 
million based on the exchange rate as of July 11, 2012, the acquisition date). We have adjusted the contingent consideration to fair value at each reporting date with changes in fair value 
recognized in operating income. At December 31, 2014, the fair value of the contingent consideration for Sentrum was £30.3 million (or approximately $47.2 million based on the exchange 
rate as of December 31, 2014) and is currently accrued in accounts payable and other accrued expenses in the consolidated balance sheet. We made earnout payments of approximately £6.2 
million (or approximately $10.3 million based on the exchange rates as of the date of each payment) during the year ended December 31, 2014. During the year ended December 31, 2013, 
we made earnout payments of approximately £16.9 million (or approximately $25.8 million based on the exchange rates as of the date of each payment). From the acquisition date through 
December 31, 2014, we have made earnout payments of approximately £23.1 million (or approximately $36.1 million based on the exchange rates as of the date of each payment). The 
change in fair value of contingent consideration for Sentrum was recorded as a reduction to operating expense of approximately $8.4 million, $1.8 million and $1.1 million for the years 
ended December 31, 2014, 2013 and 2012, respectively. The fair value of this liability will be reassessed on a quarterly basis, with any changes being recognized in earnings. Increases or 
decreases in the fair value of the liability can result from changes in discount periods, discount rates and probabilities that contingencies will be met. The earn-out contingency expires in 
July 2015.  

(c) Construction Commitments 

Our properties require periodic investments of capital for tenant-related capital expenditures and for general capital improvements and from time to time in the normal course of our 
business, we enter into various construction contracts with third parties that may obligate us to make payments. At December 31, 2014, we had open commitments related to construction 
contracts of approximately $156.5 million. 

(d) Legal Proceedings 

Although the Company is involved in legal proceedings arising in the ordinary course of business, as of December 31, 2014, the Company is not currently a party to any legal 
proceedings nor, to its knowledge, is any legal proceeding threatened against it that it believes would have a material adverse effect on its financial position, results of operations or 
liquidity.

In addition to matters discussed elsewhere in the footnotes, the following subsequent events warranted disclosure: 

On February 5, 2015, the Operating Partnership sold the 100 Quannapowitt property for approximately $31 million.The transaction after costs resulted in net proceeds of 
approximately $29 million and a net gain of approximately $9 million. The property was identified as held for sale as of December 31, 2014. 100 Quannapowitt was not a significant 
component of our U.S. portfolio nor does the sale represent a significant shift in our strategy.

ITEM 9.    CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE 

Not Applicable. 

ITEM 9A.    CONTROLS AND PROCEDURES 

Our Management’s Report on Internal Control over Financial Reporting for Digital Realty Trust, Inc. and Digital Realty Trust, L.P. are included in Part II, Item 8, Financial 

Statements and Supplementary Data on pages 89 and 90. 

Evaluation of Disclosure Controls and Procedures (Digital Realty Trust, Inc.) 

The company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its reports filed under the Securities Exchange Act 
of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms, and that such 
information is accumulated and communicated to its management, including its chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding 
required disclosure. In designing and evaluating the disclosure controls and procedures, the company’s management recognizes that any controls and procedures, no matter how well 
designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and its management is required to apply its judgment in evaluating the cost-
benefit relationship of possible controls and procedures. Also, the company has investments in certain unconsolidated entities, which are accounted for using the equity method of 
accounting. As the company does not control or manage these entities, its disclosure controls and procedures with respect to such entities may be substantially more limited than those it 
maintains with respect to its consolidated subsidiaries. 

As required by Rule 13a-15(b) or Rule 15d-15(b) of the Securities Exchange Act of 1934, as amended, management of the company carried out an evaluation, under the supervision 

and with participation of its chief executive officer and chief financial officer, of the effectiveness of the design and operation of its disclosure controls and procedures that were in effect as 
of December 31, 2014. Based on the foregoing, the company’s management concluded that its disclosure controls and procedures were effective at the reasonable assurance level. 

There have been no changes in the company’s internal control over financial reporting during its most recent fiscal quarter that have materially affected, or are reasonably likely to 

materially affect, its internal control over financial reporting. 

Evaluation of Disclosure Controls and Procedures (Digital Realty Trust, L.P.) 

The operating partnership maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its reports filed under the Securities 

Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms, 
and that such information is accumulated and communicated to its management, including the chief executive officer and chief financial officer of its general partner, as appropriate, to 
allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, the operating partnership’s management recognizes that any 
controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and its management is required to 
apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Also, the operating partnership has investments in certain unconsolidated entities, which 
are accounted for using the equity method of accounting. As the operating partnership does not control or manage these entities, its disclosure controls and procedures with respect to such 
entities may be substantially more limited than those it maintains with respect to its consolidated subsidiaries. 

As required by Rule 13a-15(b) or Rule 15d-15(b) of the Securities Exchange Act of 1934, as amended, management of the operating partnership carried out an evaluation, under the 

supervision and with participation of the chief executive officer and chief financial officer of its general partner, of the effectiveness of the design and operation of its disclosure controls 
and procedures that were in effect as of December 31, 2014. Based on the foregoing, the operating partnership’s management concluded that its disclosure controls and procedures were 
effective at the reasonable assurance level.

Exhibit 10.45

THIS FIRST AMENDMENT TO DIGITAL REALTY DEFERRED COMPENSATION PLAN (this “First Amendment”) is made and adopted by the Board of 
Directors (the “Board”) of Digital Realty Trust, Inc., a Maryland corporation (the “Company”), as of November 4, 2014. Capitalized terms used but not otherwise defined
herein shall have the respective meanings ascribed to them in the Plan (as defined below). 

WHEREAS, the Company maintains the Digital Realty Deferred Compensation Plan (the “Plan”); 

RECITALS 

WHEREAS, pursuant to Section 8.9 of the Plan, the Plan may be amended at any time by the Company’s Board of Directors (the “Board”); and  

WHEREAS, the Company desires to amend the Plan as set forth herein.  

NOW, THEREFORE, BE IT RESOLVED, that, with respect to Compensation earned on or after January 1, 2015, the Plan is hereby amended as set forth herein. 

1.    Section 1.2(u) of the Plan is hereby amended and restated in its entirety as follows: 

AMENDMENT 

“(u)      ‘Fixed  Date  Distribution’  means  a  distribution  or  distributions  of  deferred  Compensation,  together  with  any  gains  or  losses  credited
thereto, made or, in the case of installment distributions, beginning, in either case, pursuant to an Election to receive such distribution(s) on a specified
date.”  

2.    Section 3.1(d) of the Plan is hereby amended and restated in its entirety as follows: 

“(b)     Election Forms. Participants shall effectuate Elections (and any re-deferral Elections) by completing and submitting to the Committee (or
its designee) a deferral election form (which may be in paper or electronic format) prescribed by the Committee (such form, an “Election Form”) in which 
Participants specify, at a minimum:  

(i)    subject to Section 3.1(f) hereof, the levels and types of Compensation to be deferred under the Election; 

(ii)    the distribution event with respect to the Compensation deferred under the Election, which may include one or more of the following
(each,  a  “Distribution  Event”):  (i)  a  Fixed  Date  Distribution,  (ii)  the  Participant’s  Separation  from  Service,  (iii)  the  Participant’s  death  or 
Disability, which the Administrator may determine to include together in the Election Form as a single election rather than separate elections (but
which, for the avoidance of doubt, shall be treated as separate Distribution Events), and/or (iv) a Change in Control; provided, that a Participant 
may elect either a Fixed Date Distribution or a distribution upon the Participant’s Separation from Service (but not both);  

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
(iii)    to the extent that the Participant elects to receive a Fixed Date Distribution, subject to Article VI below, the specified year, if any,

during which such Fixed Date Distribution shall be made (if a lump-sum) or begin (if installments); 

(iv)    to  the  extent  that  a  Participant  elects  to  receive  a  distribution  in  the  event  of  the  Participant’s  Separation  from  Service,  the 
Participant  may  (but  is  not  required  to)  specify  in  an  Election  Form  whether  the  distribution  shall  be  made  (if  a  lump-sum)  or  begin  (if 
installments) on the Payment Date that occurs in the second (2nd), third (3rd), fourth (4th), fifth (5th), sixth (6th), seventh (7th), eighth (8th), ninth (9th) or 
tenth (10th) calendar year immediately following the calendar year in which the Participant incurs a Separation from Service (any such election, a
“Post-Separation Election”). For the avoidance of doubt, if a Participant does not make a Post-Separation Election, amounts distributable upon 
the  Participant’s  Separation  from  Service  shall  be  made  or  commence,  as  applicable,  on  the  Payment  Date  that  occurs  in  the  calendar  year
immediately following the calendar year in which the Participant incurs a Separation from Service pursuant to Section 6.1(b) below; 

(v)    the form of payment applicable to distributions of the Participant’s Account or Subaccount, which may be either lump-sum or up to 

ten (10) installments; and 

(vi)    subject  to  Section  3.2  hereof,  the  allocation  of  deferred  Compensation  and/or  earnings  thereon  amongst  available  Investment

Alternatives in accordance with the terms of the Plan.”  

3.    Section 3.1(e) of the Plan is hereby amended and restated in its entirety as follows: 

“(e)     Priority of Distributions. Of the Distribution Events specified by a Participant in an applicable Election Form, the first such Distribution
Event to occur shall govern the distributions of the amounts subject to such Election and distributable on such distribution event. For the avoidance of
doubt, if a Participant experiences a Separation from Service, dies, or experiences a Disability, or a Change in Control occurs, in any case, prior to the
completion  of  any  Fixed  Date  Distribution  installment  payments  which  have  commenced  prior  to  such  Separation  from  Service,  death,  Disability  or
Change in Control, as applicable, amounts subject to such Fixed Date Distribution Election shall continue to be distributed in installments in accordance
with Section 6.1(a) hereof.” 

4. 

Section  3.3  of  the  Plan  is  hereby  renumbered  as  Section  3.2  of  the  Plan,  and  each  reference  therein  to  “Section  3.3”  of  the  Plan  (or  any  subsection  of 
“Section 3.3”) is hereby amended to refer to “Section 3.2” of the Plan or such subsection of Section 3.2 thereof, as applicable. 

5.    Section 6.1(a) of the Plan is hereby amended and restated in its entirety as follows: 

“(a)      Fixed  Date  Distributions.  With  respect  to  Elections  to  receive  a  Fixed  Date  Distribution,  a  Participant  may  elect  to  receive  his  or  her
Account or Subaccount (determined on a Plan Year basis) in (i) two (2) to ten (10) annual installments, or (ii) a lump sum, in each case, as specified by the
Committee in an Election Form. Payment  

2 

 
 
 
 
 
 
 
 
shall be made or commence, as applicable, on the Payment Date that occurs during the specified year of such Fixed Date Distribution.” 

6.    Section 6.1(b) of the Plan is hereby amended and restated in its entirety as follows: 

“(b)     Separation from Service. With respect to Elections to commence distributions upon a Separation from Service, a Participant may elect to
receive his or her Account or Subaccount (determined on a Plan Year basis) in (i) two (2) to ten (10) annual installments as specified by the Committee in
an Election Form, or (ii) a lump sum. Subject to Section 6.2 below, payment shall be made or commence, as applicable, on the Payment Date that occurs
in the calendar year immediately following the calendar year in which the Participant incurs a Separation from Service or, if the Participant has made a
Post-Separation Election, on the Payment Date that occurs in the second (2nd), third (3rd), fourth (4th), fifth (5th), sixth (6th), seventh (7th), eighth (8th), ninth 
(9th) or tenth (10th) calendar year (as specified in the Post-Separation Election) following the calendar year in which the Participant incurs a Separation
from Service.” 

7.    This First Amendment shall only be effective with respect to Compensation earned on or after January 1, 2015. 

8.    This First Amendment shall be and is hereby incorporated in and forms a part of the Plan. 

9.    Except as expressly provided herein, all terms and provisions of the Plan shall remain in full force and effect.
