EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the year ended December 31, 2016 of DuPont Fabros Technology, Inc. and DuPont Fabros Technology, L.P. References to “DFT” mean DuPont Fabros Technology, Inc. and its controlled subsidiaries; and references to the “Operating Partnership” or “OP” mean DuPont Fabros Technology, L.P. and its controlled subsidiaries. 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 DFT and the Operating Partnership, collectively.

DFT is a real estate investment trust (“REIT”) and the general partner of the Operating Partnership. The Operating Partnership’s capital includes general and limited common operating partnership units, or “OP units.” As of December 31, 2016, DFT owned 84.9% of the common economic interest in the Operating Partnership, with the remaining interest being owned by investors. As the sole general partner of the Operating Partnership, DFT has exclusive control of the Operating Partnership’s day-to-day management.

We believe combining the annual reports on Form 10-K of DFT and the Operating Partnership into this single report provides the following benefits:

• enhances investors’ understanding of DFT 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;

• eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure in this report applies to both DFT and the Operating Partnership; and

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

We operate DFT and the Operating Partnership as one business. The management of DFT consists of the same employees as the management of the Operating Partnership.

We believe it is important for investors to understand the few differences between DFT and the Operating Partnership in the context of how DFT and the Operating Partnership operate as a consolidated company. DFT is a REIT, whose only material asset is its ownership of OP units of the Operating Partnership. As a result, DFT 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 unsecured debt of the Operating Partnership. DFT has not issued any indebtedness, but has guaranteed all of the unsecured debt of the Operating Partnership. The Operating Partnership, through its wholly-owned subsidiaries, holds all the real estate assets of the Company. Except for net proceeds from public equity issuances by DFT, which are contributed to the Operating Partnership in exchange for OP units or preferred units, the Operating Partnership generates all remaining capital required by our business. These sources include the Operating Partnership’s operations, its direct or indirect incurrence of indebtedness, and the issuance of partnership units.

As sole general partner with control of the Operating Partnership, DFT consolidates the Operating Partnership for financial reporting purposes. The presentation of stockholders’ equity and partners’ capital are the main areas of difference between the consolidated financial statements of DFT and those of the Operating Partnership. The Operating Partnership’s capital includes preferred units and general and limited common units that are owned by DFT and the other partners. DFT’s stockholders’ equity includes preferred stock, common stock, additional paid in capital, retained earnings and accumulated other comprehensive income (loss). The common limited partnership interests held by the limited partners (other than DFT) in the Operating Partnership are presented as “redeemable partnership units” in the Operating Partnership’s consolidated financial statements and as “redeemable noncontrolling interests-operating partnership” in DFT’s consolidated financial statements. The only difference between the assets and liabilities of DFT and the Operating Partnership as of December 31, 2016 was a $4.2 million bank account held by DFT that is not part of the Operating Partnership. Net income is the same for DFT and the Operating Partnership.

In order to highlight the few differences between DFT and the Operating Partnership, there are sections in this report that discuss DFT and the Operating Partnership separately, including separate financial statements, controls and procedures sections, and Exhibit 31 and 32 certifications. In the sections that combine disclosure for DFT 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, holds assets and issues debt, we believe that reference to the Company in this context is appropriate because the business is one enterprise and we operate the business through our Operating Partnership.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

The following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report. This report contains forward-looking statements within the meaning of the federal securities laws. We caution investors that any forward-looking statements presented in this report, or which management may make orally or in writing from time to time, are based on management's beliefs and assumptions made by, and information currently available to, management. When used, the words “anticipate,” “believe,” “expect,” “intend,” “may,” “might,” “plan,” “estimate,” “project,” “should,” “will,” “result” and similar expressions, which do not relate solely to historical matters, are intended to identify forward-looking statements. Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance, which may be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. We caution you that while forward-looking statements reflect our good faith beliefs when we make them, they are not guarantees of future performance and are impacted by actual events when they occur after we make such statements. We expressly disclaim any responsibility to update forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. Accordingly, investors should use caution in relying on past forward-looking statements, which are based on results and trends at the time they are made, to anticipate future results or trends.

Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following:

• adverse general or local economic or real estate conditions in our markets or the technology industry, including a continued and prolonged economic downturn;

• failure to lease available space in our properties on a timely basis or at favorable net effective rental rates;

• decreased rental rates or rates of return on our investments, increased vacancy rates or customer bankruptcies;

• defaults on or non-renewal of leases by customers, including by our two largest customers that accounted for 25.4% and 20.2%, respectively, of our annualized base rent as of December 31, 2016;

• failure to collect customer obligations and note receivables;

• failure to obtain necessary financing, extend the maturity of or refinance our existing debt, or comply with the financial and other covenants of the agreements that govern our existing debt;

• increased interest rates;

• financial market fluctuations, including disruptions in the financial and credit markets and the availability of capital and other financing;

• the risks commonly associated with the acquisition of development sites, construction and development of new facilities (including delays and/or cost increases associated with the completion of new developments), risks relating to obtaining required permits and compliance with permitting, zoning, land-use and environmental requirements;

• the failure to qualify and maintain qualification as a real estate investment trust, or REIT;

• adverse changes in tax laws;

• environmental uncertainties;

• risks related to natural disasters; and

• changes in real estate and zoning laws.

For a detailed discussion of certain risks and uncertainties that could cause our future results to differ materially from any forward-looking statements, see the risk factors described in Item 1A herein and in other documents that we file from time to time with the Securities and Exchange Commission (“SEC”). The risks and uncertainties discussed in these reports are not exhaustive. We operate in a very competitive and rapidly changing environment and new risk factors may emerge from time to time. It is not possible for us to predict all such risk factors, nor can we assess the impact of all such risk factors on our 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. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

PART I

ITEM 1. BUSINESS

DuPont Fabros Technology, Inc. (“DFT”) is a fully integrated, self-administered and self-managed real estate investment trust, or REIT, that owns, acquires, develops and operates wholesale data centers. DFT is the sole general partner of, and, as of December 31, 2016, owned 84.9% of the common economic interest in, DuPont Fabros Technology, L.P. (the “Operating Partnership” or “OP”). Unless otherwise indicated or unless the context requires otherwise, all references to “we,” “us,” “our,” “our Company” or “the Company” refer to DFT and the Operating Partnership, collectively.

We design and operate innovative, multi-tenant, wholesale data centers, and create solutions with our customers that free them to focus on their core businesses. Our facilities are designed to offer highly specialized, efficient and safe computing environments in a low-cost operating model. Our customers include national and international enterprises across numerous industries, including technology, Internet, content providers, cloud providers, media, communications, healthcare and financial services. Our 11 data centers have a total of 3.3 million gross square feet and 287 megawatts of power available to our customers to operate their servers and computing equipment. For the year ended December 31, 2016, we generated $528.7 million of total revenues, net income of $181.4 million and cash provided by operating activities of $290.0 million. As of December 31, 2016, we had total assets of $3.0 billion.

Data centers are facilities that house large numbers of computer servers and related equipment and include the infrastructure necessary to operate this equipment, including systems for power distribution, environmental control, fire suppression and security. We believe that our data centers provide sufficient power to meet the needs of the world's largest technology companies. We lease the computer room square feet, or CRSF, and the available power of our facilities to customers under long-term leases. As of January 1, 2017:

• We had 32 customers with 124 different lease expirations, with only 14.2% of these expirations occurring over the next two years as measured by annualized base rent;

• The weighted average remaining term of our leases at our operating data centers was 5.4 years; and

• We served five of the Fortune 25 and 20 of the Fortune 1000, which includes private or foreign enterprises of equivalent size.

Our data centers are strategically located in three major population centers - Northern Virginia, suburban Chicago, Illinois and Santa Clara, California. We have acquired property and have plans to expand into two new markets - the greater Toronto area, and the Portland, Oregon metropolitan area. Each of our current and expansion markets has significant electrical power availability and hubs of extensive fiber network connectivity. As of December 31, 2016, we owned the following properties:

• 11 operating data centers facilities;

• Five phases of existing data center facilities under development;

• One shell of a data center currently under development;

• Two data center facilities with a phase or phases available for future development; and

• Parcels of land held for future development of four data centers.

We believe that we are well positioned to develop, lease, operate and manage our growing data center portfolio.

We derive substantially all of our revenue from rents received from customers. For most of our customers, and we believe for most potential wholesale data center customers, the amount of available power is the primary factor used to evaluate their data center requirements. Consequently, rents under our leases are based primarily on the amount of power made available to our customers, rather than the amount of space that they occupy. The term “critical load” is used to indicate that portion of each facility's total power capacity that is made available for the exclusive use of its customers to operate their computer servers. Accordingly, throughout this Form 10-K, we discuss our operations in terms of available critical load because it is one of the primary metrics that we use to manage our business. We also provide information relating to each facility's total gross building area and its computer room square feet ("CRSF"), which is the net rentable area of each of our facilities.

We also provide certain technical services to customers as a contractor on a purchase order basis, including layout design and installation of electrical power circuits, data cabling, server cabinets and racks, computer room airflow analyses and monitoring and other services requested by customers.

Market Opportunity

The data center market in North America is highly fragmented with more than 500 companies providing different forms of multi-tenant data center services, although not all data center providers serve the wholesale segment of the data center market. Wholesale data center providers lease large amounts of space, which can range in size from 2,500 to 50,000 square feet or more, and make available large amounts of power, which can range from 250 kilowatts to 10 MW or more, to a limited number of customers. Typically, in wholesale data centers, each customer’s space is segregated with cages or in separate rooms within the data center, commonly referred to as computer rooms or pods. Also, typically, each customer owns and operates its own servers and related computer equipment. This model gives customers the flexibility to design their own server layout and manage the operation of their servers; generally offers greater power within a single data center facility, which provides savings on the cost to operate the data center infrastructure through economies of scale; and provides secure facilities with security and technical staff on-site 24 hours a day, seven days a week to protect and support the critical business processes of the customers operating their servers.

We believe that the growth trends in the data center market, the cloud, Internet traffic and Internet-based services, combined with cost advantages in outsourcing data center requirements, provide attractive growth opportunities for us. The compound annual growth rate of North American data center market revenue from 2015 through 2020 is expected to be approximately 10.9% based on annual forecast data in the Multi-Tenant Datacenter Global Providers 2016 report published by 451 Research in October 2016. We believe that this growth is the result of significant growth of the Internet, cloud and data storage. According to the Cisco Visual Networking Index (VNI) 2015-2020 White Paper, global Internet traffic is expected to increase at a compound annual growth rate of 22%, mobile data traffic is expected to increase at a compound annual growth rate of 53%, and global video traffic is expected to increase at a compound annual growth rate of 31% from 2015 to 2020.

We believe that companies can realize numerous advantages by outsourcing their data center requirements to wholesale providers, rather than building and operating their own data center facilities. Over our operating history, we have observed that large, wholesale data center facilities offer economies of scale that result in lower operating costs, as compared to the cost to operate smaller facilities. We believe that only companies with very large computing requirements can realize these economies from developing, owning and operating their own data center facilities. We also believe that these advantages in outsourcing data center requirements, combined with the expected growing trends for traffic, provide an opportunity for us to grow our data center portfolio and realize attractive rates of return on the investments in our facilities.

Business Strategy

Our goal is to diversify our customer base and improve our profitability by expanding our geographic presence and supplementing our portfolio with flexible wholesale products. We will continue to serve the wholesale segment of the data center market exclusively. We will capitalize on our exceptional skill in data center design, development and operations as we build-out our development pipeline and maximize cash flow from our existing properties. Specifically, we will expand our geographic presence; diversify our portfolio with flexible wholesale products to meet a variety of power density, redundancy and deployment needs and continue to prudently build-out our development pipeline.

Expand Our Geographic Presence. Our primary focus in the past has been to develop and lease data center space in the three markets in which we operate. Over the next several years, we plan to expand our data center development and operations into several new markets, which we believe will create opportunities to diversify our customer base and increase our profitability. We plan to target two new markets that we believe will satisfy demand of wholesale customers. Initially, we intend to focus our development efforts in the Toronto, Ontario and Portland, Oregon markets, where we believe that there will be strong demand for wholesale data centers even though the development of a wholesale market in these markets is in its infancy.

In July 2016, we purchased a 46.7 acre parcel of land in the Portland market, and in September 2016, we purchased a shell building and associated land in the Toronto market. The building in Toronto is a former Toronto Star printing facility, and the shell is well-suited for development of our TOR1 data center. We have begun development of Phase IA of TOR1 and expect to deliver this phase later in 2017.

Diversify our portfolio with flexible wholesale products to meet a variety of power density, redundancy and deployment needs. The data center requirements of prospective customers vary greatly between the Internet, cloud and technology industries, on the one hand, and enterprises, on the other. There are three key areas where customer requirements vary:

6

• Power Density, which is the amount of power available in a fixed amount of space. Many Internet, cloud and technology customers require “high-density” space, or a large amount of power relative to the space, while many enterprise customers require “low density” space, or a smaller amount of power relative to the space. Our more recent data center facility designs (ACC6 Phase II, ACC7, ACC9, CH2, CH3 and SC1 Phase II) provide some flexibility to meet different customers’ density requirements, but we have developed a new design that will enable us to meet a larger variety of density requirements for different customers within a single facility. This new design will be deployed in the Toronto, Ontario and Portland, Oregon markets.

• Redundancy, which means the number of additional power distribution, cooling units and back-up diesel engine generators included in a facility design to back-up units that are off-line for maintenance or due to a malfunction. Each of our current operating data center facilities are designed with “N+2” redundancy, which means that our facilities include two sets of power distribution systems and back-up diesel engine generators in addition to the number of these sets of units necessary to provide the power contracted by our customers. Our facilities also have this level of redundancy for our mechanical plants, which regulate the environment of the computer rooms leased by our customers. We believe that some customers require N+1 redundancy or less, and that a few customers may require redundancy more robust than N+2. Consequently, we have developed a new data center design that will enable us to meet diverse redundancy requirements of potential customers within a single facility. This new design will be deployed in the Toronto, Ontario and Portland, Oregon markets. Additionally, our CH3 and ACC10 data centers while based on our current design will be developed with N+1 redundancy.

• Deployment needs, which relates to the time that it takes to construct a phase of a facility and ready it for a customer’s operations. Although we generally commence development of a data center facility prior to having received any commitments from customers to lease any space in the facility - commonly known as developing “on speculation” - we have found that customers often need data center space within very specific, and often short, time frames. Although our current data center development time lines allow for rapid deployment of computer room space, we have completed a new design that we believe will improve our development times and allow us to meet specific customer requirements for available computer room space.

Continue to prudently build-out our development pipeline. We determine when to develop data center properties based on the amount of available space in our operating properties and anticipated demand for data center space in each applicable market. Our development projects as of December 31, 2016 included:

• ACC9 Phase I - 14.4 MW of available critical load which was 20% pre-leased as of February 23, 2017, with completion expected in the second quarter of 2017;

• ACC9 Phase II - 14.4 MW of available critical load with completion expected in the third quarter of 2017;

• SC1 Phase III - 16.0 MW of available critical load which was 100% pre-leased, with completion expected in the third quarter of 2017;

• TOR1 Phase IA - 6.0 MW of available critical load with completion expected in the third quarter of 2017;

• CH3 Phase I - 13.6 MW of available critical load with completion expected in the first quarter of 2018; and

• ACC10 shell is currently in development. Building the shell now will allow us to deliver phases I and II quicker as demand warrants.

The remaining phases of TOR1, comprising 28.5 MW, and the second phase of CH3, comprising 13.6 MW, are being held for future development. We also own parcels of land available to develop four additional data centers, two of which are in the Ashburn, Virginia market and the other two are in the Portland, Oregon market.

Competitive Strengths

We believe that we distinguish ourselves from other data center providers through the following competitive strengths:

Long-term leases to industry-leading customers with strong credit. Our customer base includes leading national and international technology companies. As of January 1, 2017, our two largest customers, Microsoft Corporation and Facebook, Inc., which are currently under long term leases with staggered lease expirations, accounted for 25.4% and 20.2%, respectively, of our annualized base rent. We generally lease space and power to our customers using a “triple net” lease structure, under which our customers occupy all or a percentage of each of our data centers and, in addition to a monthly base rent fee, are obligated to reimburse us for their share of property-level operating expenses. We also have begun to market space and power to customers under a “full service” lease structure, under which both the monthly base rent and a fee for the property-level

7

operating expenses are fixed, at rates which we believe will cover these operating expenses and will provide us with an adequate return on our investment. We signed twelve triple net leases and two full service leases in 2016. Under all of our leases, customers reimburse us for the cost of the power they use to operate their computer servers and the power that is used to cool their space, and generally provide for annual increases of base rent - either a flat rate of about 2-3% or based on the consumer price index. We believe that these lease structures, together with the economies of scale resulting from the size of our data centers, result in our customers paying less for power and operating expenses over time than they would in a comparable colocation setting, where power costs are often included in the license fee paid to the provider. Most of our leases provide for annual rent increases, and, as of January 1, 2017, our weighted average remaining lease term was approximately 5.4 years.

Data centers strategically located with high power capacity. We own operating facilities and properties available for data center development in the Northern Virginia, suburban Chicago, Illinois and Santa Clara, California markets, each of which is located near sources of abundant and relatively inexpensive power, major population centers and significant fiber optic networks. We believe that these locations help attract and retain customers because access to less expensive power yields significant cost savings for our customers, and the proximity to large population centers enhances performance by reducing latency, which is the time it takes a packet of information to reach the end user. We are expanding into the Toronto, Ontario and Portland, Oregon markets, where we believe that there will be strong demand for wholesale data centers even though the development of a wholesale market there is in its infancy.

Strong development track record and pipeline. We currently own and operate 11 data centers. As of December 31, 2016, eight of these facilities were 100% leased, and 97% of our operating portfolio was leased based on critical load. We believe that our in-house development expertise, together with our relationships with contractors who are experienced in the construction of data centers, gives us a significant advantage over those of our competitors who are required to rely exclusively on third parties to develop, lease and maintain their properties. We currently have undeveloped property or parcels of land suitable for data center development in our Northern Virginia and Portland, Oregon markets.

Properties

Operating Properties

For the year ended December 31, 2016, we executed 14 leases totaling 50.93 MW of critical load and 267,662 CRSF with a weighted average lease term of 12.2 years. In addition, for the year ended December 31, 2016, we extended the terms of eight leases that comprise a total of 7.97 MW of critical load and 54,139 CRSF for a weighted average of 2.3 years. The weighted average base rent, measured on a generally accepted accounting principles ("GAAP") basis, for all of the leases that have commenced at our operating properties as of December 31, 2016, was $102 per kilowatt per month. This amount excludes operating expenses.

(1) Stabilized operating properties are either 85% or more leased and commenced or have been in service for 24 months or greater.

(2) Gross building area is the entire building area, including CRSF (the portion of gross building area where our customers' computer servers are located), common areas, areas controlled by us (such as the mechanical, telecommunications and utility rooms) and, in some facilities, individual office and storage space leased on an as available basis to our customers.

(3) Percentage leased is expressed as a percentage of CRSF or critical load, as applicable, that is subject to an executed lease. Leases executed as of January 1, 2017 represent $371 million of base rent on a GAAP basis and $379 million of base rent on a cash basis over the next twelve months. Both amounts include $19 million of revenue from management fees over the next twelve months.

(4) Percentage commenced is expressed as a percentage of CRSF or critical load, as applicable, where the lease has commenced under generally accepted accounting principles.

(5) Critical load (also referred to as IT load or load used by customers' servers or related equipment) is the power available for exclusive use by customers expressed in terms of megawatt, or MW, or kilowatt, or kW (1 MW is equal to 1,000 kW).

(6) As of February 23, 2017, ACC7 is 100% leased and commenced based on critical load and 98% leased and commenced based on CRSF.

Customer Diversification

As of January 1, 2017, our operating property portfolio had 32 data center customers with 124 different lease expiration dates. As of January 1, 2017, our largest customer, Microsoft, accounted for 25.4% of our annualized base rent. As of January 1, 2017, we had commenced leases with Microsoft in nine of our data centers with 29 lease expiration dates ranging from December 31, 2017 to September 30, 2031 and options by Microsoft to renew six of these lease expiration dates from six months to five years, 12 expiration dates for five years and two expiration dates from one to five years. Nine of these lease expiration dates have no renewal options. In addition, Microsoft has early termination options for six of its lease expiration dates. For one expiration date, Microsoft has the right to make a termination payment and terminate this lease on either March 31, 2021 or March 31, 2026. This lease is shown as expiring in 2021 in the Lease Expiration Table. For three other expiration dates, Microsoft has the right to make a termination payment and terminate these leases on either June 30, 2026 or July 31, 2026. For two other lease expiration dates, Microsoft has the right to make a termination payment and terminate these leases on September 30, 2026. These last five expiration dates are shown as expiring in 2031 in the Lease Expiration Table after taking into account the termination payment options relative to the remaining payments due under each lease. Please visit www.microsoft.com to obtain this customer's SEC filed financial information.

As of January 1, 2017, our second largest customer, Facebook, accounted for 20.2% of our annualized base rent. As of January 1, 2017, we had commenced leases with Facebook in four of our data centers with 17 lease expiration dates ranging from June 30, 2018 to February 28, 2023 and an option by Facebook to renew the term of the lease of any computer room by a duration of between 6 months and 5 years. Facebook has the right to decrease the term of the lease of each of nine of its existing computer rooms in ACC5, each with 2.28 MW of available critical load, provided the aggregate reduction in lease term does not exceed 67 months, or an average of approximately seven months per computer room.

(1) Represents 32 customers with 124 lease expiration dates. One additional customer has executed a pre-lease at ACC9 and will be our 33rd customer.

(2) CRSF is that portion of gross building area where customers locate their computer servers. One MW is equal to 1,000 kW.

(3) Annualized base rent represents the monthly contractual base rent (defined as cash base rent before abatements) multiplied by 12 for commenced leases as of January 1, 2017.

(4) A customer at ACC4 whose lease expires on July 31, 2017 has informed us that they do not intend to renew this lease. This lease is for 1.14 MW and 5,400 CRSF. Additionally, a customer at ACC6, whose lease expires on August 31, 2017, has informed us that they do not intend to renew this lease. This lease is for 0.54 MW and 2,523 CRSF. These leases total 0.9% of Annualized Base Rent. We are marketing these computer rooms for re-lease.

As of January 1, 2017, our operating property portfolio had 32 data center customers with 124 lease expiration dates. As of January 1, 2017, as described above, we had leases with our largest customer that have 29 lease expiration dates ranging from December 31, 2017 to September 30, 2031, with various renewal rights and, with respect to six lease expiration dates, an option to terminate the lease prior to the expiration date. Also, as discussed above, as of January 1, 2017, we had leases with our second largest customer that have 17 lease expiration dates ranging from June 30, 2018 to February 28, 2023, with various renewal rights and, with respect to its ACC5 lease, an option to decrease the term of the lease of each of nine of its existing computer rooms, provided the aggregate reduction in lease term does not exceed 67 months, or an average of approximately seven months per computer room.

Some leases with certain other customers include options to terminate leases prior to the expiration date. For instance, as of January 1, 2017, we had commenced leases with our third largest customer in three of our data centers with 12 expiration dates ranging from September 30, 2021 to June 30, 2022. This customer has an option to renew the term of each of these lease expiration dates for five years. With respect to six of these lease expiration dates, this customer has the option to make a termination payment and terminate these leases on September 30, 2018. These leases are shown as expiring in 2018 in the Lease Expiration Table above. Also, as of January 1, 2017, we had commenced leases with our fourth largest customer in three of our data centers with nine expiration dates ranging from June 30, 2024 to December 31, 2033. This customer has the option to renew the term of each of these lease expiration dates for five years. With respect to six of its lease expiration dates, this customer has the option to make a termination payment and terminate these leases after ten years of the respective lease terms

11

with expiration dates ranging from June 30, 2019 to May 31, 2024. These lease expiration dates are shown as expiring after ten years in the Lease Expiration Table above. In addition, as of January 1, 2017, we had commenced leases with our fifth largest customer in four of our data centers with 12 expiration dates ranging from July 31, 2022 to March 31, 2026. This customer has the option to renew the term of two of these lease expiration dates for between one and five years and 10 leases with an option to renew for five years. This customer has an option on ten lease expiration dates to make a termination payment and terminate the lease on dates ranging from March 31, 2018 to June 30, 2022. Two of these leases are shown as expiring March 31, 2018. Certain other customers have similar rights to terminate leases prior to their expiration dates.

Competition

We believe we have two types of competitors:

• Owners, operators and developers of both wholesale and colocation data centers, and

• Companies who choose to build, own and operate their own data centers rather than outsource, some of which are customers of ours.

The data center market in North America is highly fragmented with more than 500 companies providing different forms of multi-tenant data center services. We compete with many of these companies, including other REITs in the data center industry, such as CoreSite Realty Corporation, CyrusOne Inc., Digital Realty Trust Inc., Equinix, Inc. and QTS Realty Trust, Inc. In operating and managing our portfolio, we compete for customers based on factors including location, available critical load, amount of CRSF, flexibility, total cost for the customer and expertise in the design and operation of data centers.

Some companies with very large computing requirements, including some of our customers, such as Microsoft and Facebook, own and operate their own data center facilities for a portion of their computing requirements. These companies may choose in the future to expand their data centers or develop additional data center facilities. Nevertheless, we believe that many of these customers will continue to outsource at least a portion of their data center requirements because of demand for data center space, often within very short time frames, and the expected growing trends in the cloud, Internet traffic and Internet-based services.

We also face competition for the acquisition of land suitable for the development of wholesale data centers from real estate developers in our industry and in other industries. Such competition may have the effect of reducing the number of available properties for acquisition, increasing the price of any acquisition, and reducing the supply of wholesale data center space in the markets we seek to serve.

Regulation

Environmental Matters

We are required to obtain a number of permits from various government agencies to construct a data center facility, including the customary zoning, land use and related permits, and permits from state and local environmental regulatory agencies related to the installation of the diesel engine generators that we use for emergency back-up power at our facilities. In addition, various environmental agencies that regulate air quality require that we obtain permits for the operation of our diesel engine generators. These permits set forth specified levels of certain types of emissions permitted from these engines, such as nitrogen oxides. Changes to any applicable regulations, including changes to air quality standards or permitted emissions levels, that are applicable to us, or our ability to obtain the necessary permits to install or operate diesel engines, could delay or preclude our ability to construct or operate data center facilities.

Under various federal, state and local laws, regulations and ordinances relating to the protection of the environment, a current or former owner, operator or customer of real property may be liable for the cost to remove or remediate contamination resulting from the presence or discharge of hazardous or toxic substances, wastes or petroleum products on, under, from or in such property. These costs could be substantial and liability under these laws may attach 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. Previous owners of the sites where some of our data center facilities are located (CH1, CH2, and SC1), and the undeveloped land for our ACC8 and ACC11 facilities, used these sites for industrial or retail purposes, and, therefore, each of those properties may contain some level of environmental contamination. In addition, many of our properties presently contain large fuel storage tanks that we use to power our back-up engine generators. If any of these tanks were to release fuel into the environment, we would likely have to pay to clean up the contamination. The presence of contamination or the failure to remediate contamination at any of our properties may expose us to third-party liability, which could be for amounts that are material, or may materially adversely affect our ability to sell, lease or develop the contaminated property or to borrow capital using the contaminated property as collateral for the loan.

Some of our properties may contain asbestos-containing building materials. Environmental laws require that owners or operators of buildings with asbestos-containing building materials properly manage and maintain these materials, adequately inform or train those who may come into contact with asbestos and undertake special precautions, including removal or other

13

abatement, in the event that asbestos is disturbed during building renovation or demolition. These laws may impose fines and penalties on building owners or operators for failure to comply with these requirements. In addition, 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.

Environmental laws and regulations regarding the handling of regulated substances and wastes apply to our properties, in particular regulations regarding the storage of petroleum for emergency/auxiliary power. The properties in our portfolio are also subject to various federal, state and local health and safety requirements, such as state and local fire requirements. If we or our customers fail to comply with these various requirements, we might incur governmental fines or private damage awards. Moreover, we do not know whether existing requirements will change or whether future requirements will require us to make significant unanticipated expenditures that will materially adversely impact our financial condition, results of operations, cash flow, cash available for distributions, the per share trading price of our common stock and our ability to satisfy our debt service obligations. We require our customers to comply with these environmental, health and safety laws and regulations and to indemnify us for any related liabilities. Environmental noncompliance liability could also affect a customer's ability to make rental payments to us.

Although each of our properties has been subjected to Phase I environmental site assessments, they are limited in scope, and may not identify all potential environmental liabilities or risks associated with these properties. Unless required by applicable laws or regulations, we may not further investigate, remedy or ameliorate any liabilities disclosed in the Phase I assessments.

Americans With Disabilities Act

Our properties must comply with Title III of the Americans with Disabilities Act, or 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. While we have not conducted a formal audit or investigation of our compliance with the ADA, we believe that our operating 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 ongoing, and we will continue to assess our properties and make alterations as appropriate in this respect.

Insurance

We carry comprehensive liability, fire, extended coverage, business interruption and rental loss insurance covering all of the properties in our portfolio, which includes coverage for riots, terrorism, earthquakes, acts of God and floods. We have 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 our opinion, the properties in our portfolio are currently adequately insured. See “Item 1A. - Risk Factors - Risks Related to Our Business and Operations - Any losses to our properties that are not covered by insurance, or that exceed our policy coverage limits, would materially adversely affect our business, results of operations and financial condition.” Some risks to our properties, such as losses due to war, floods and earthquakes, are either not currently insured against or are insured subject to policy limits that may not be sufficient to cover all of our losses.

Employees

As of December 31, 2016, we had 122 employees, with approximately 70% located at our various data centers in Northern Virginia; suburban Chicago, Illinois; Santa Clara, California and the remainder located in Washington, D.C. at our corporate headquarters. We believe our relations with our employees are good.

Offices

Our headquarters are located at 401 9th Street NW, Suite 600, Washington, D.C. 20004, and our telephone number is (202) 728-0044. As of December 31, 2016, we leased approximately 22,000 square feet of office space in the building at the address set forth above. We believe our offices are adequate for our current operations.

ITEM 1.A RISK FACTORS

Set forth below are the risks that we believe are material to our stockholders. You should carefully consider the following risks in evaluating our company, our properties and our business. The occurrence of any of the following risks could materially adversely impact our financial condition, results of operations, cash flow, the per share trading price of our common stock and our ability to, among other things, satisfy our debt service obligations and to make distributions to our stockholders, which in turn could cause our stockholders 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 “Special Note Regarding Forward-Looking Statements” at the beginning of this annual report.

Risks Related to Our Business and Operations

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

We compete with numerous developers, owners and operators of technology-related real estate, including CoreSite Realty Corporation, CyrusOne Inc., Digital Realty Trust, Inc., Equinix, Inc. and QTS Realty Trust. Many of these 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, all of which allow them to respond more quickly to new or changing opportunities. Many of these competitors own properties similar to ours in the same markets in which our properties are located, or in markets where the cost to operate a data center is less than the cost to operate our data centers. Many of our competitors and new entrants to the data center market are developing additional data center space in the markets that we serve. If the supply of data center 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 or new data center space that we develop, which could have a material adverse effect on our business, results of operations and growth prospects. These risks may be exacerbated if new data center developers, owners or operators enter the data center market.

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

Although as of January 1, 2017, only 6.3 MW of critical load was available for lease and leases that represent less than 2% of critical load power under lease were scheduled to expire in 2017, we expect to complete developments with 50.8 MW of critical power available for lease during 2017, of which 18.9 MW is pre-leased. We may not be able to attract customers for this space or renew these expiring leases with our existing customers, or we may be required to reduce our rental rates or incur costs, if our competitors:

• offer rental rates below current market rates, or below the rental rates we are offering;

• offer space that our customers or potential customers perceive to be superior to ours based on numerous factors, including available power, preferred design features, security considerations, location, and connectivity; or

• offer services that we do not offer and that customers or potential customers desire.

If we are unable to lease available space, or if we are unable to lease available space on a timely basis or at favorable net effective rental rates, it could have a material adverse effect on our business, results of operations and growth prospects.

Any decrease in the demand for data centers, including a decrease resulting from a downturn in the technology industry or the demand for cloud-based services, could materially adversely affect our business, results of operations and financial condition.

Our portfolio of properties consists entirely of wholesale data centers leased primarily to Fortune 1000 Internet, software and other technology-based companies, many of which provide cloud-based services. A decline in the technology industry or the demand for cloud-based services, or the desire of any of these companies to outsource their data center needs, could lead to

15

a decrease in the demand for space in our data centers, which would have a greater adverse effect on our business and financial condition than if we owned a more diversified real estate portfolio. We also are susceptible to adverse developments in the industries in which our customers operate, such as decreases in demand for their products or services, business layoffs or downsizing, industry slowdowns, relocations of businesses, costs of complying with government regulations or increased regulation and other factors. We also may be materially adversely affected by any downturns in the market for data centers due to, among other things, oversupply of or reduced demand for space or a slowdown in web-based commerce. Also, a lack of demand for data center space by enterprise customers could have a material adverse effect on our business, results of operations and financial condition.

Our customers 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 customers or reduce demand for our newly developed data centers, which could have a material adverse effect on our business, results of operations and financial condition.

Some of our customers, including Microsoft and Facebook, own and operate their own data center facilities for a portion of their computing requirements, and may choose in the future to expand their data centers or develop additional data center facilities. If any of our key customers were to reduce their reliance on outsourced data center facilities, it could result in a loss of business to us or put pressure on our pricing. If we lose a customer, there is no assurance that we would be able to replace that customer at a competitive rate or at all, which could have a material adverse effect on our business, results of operations and financial condition.

As of January 1, 2017, our two largest customers, Microsoft and Facebook, accounted for 25.4% and 20.2%, respectively, of our annualized base rent, and the loss of any such customer or any other significant customer, or the inability of any such customer or any other significant customer to pay rent and other expenses as due, could have a material adverse effect on our business, results of operations and financial condition.

Any of our customers could experience a downturn in their business, which in turn could result in their inability or failure to make timely rental payments pursuant to their leases with us. In the event of any customer default, we may experience delays in enforcing our rights as landlord and may incur substantial costs in protecting our investment. These risks would be particularly significant if one of our four largest customers were to default under their leases. Also, some of our largest customers compete with one another in various aspects of their businesses. The competitive pressures on our customers may have a negative impact on our operations.

In addition, because we have only 33 different customers, the inability of a customer to meet its rent obligations could impact us negatively and significantly.

In addition, if one or more of our significant customers fail to renew their leases with us, or if any of them exercise any applicable early termination rights, and we are unable to find new customers to utilize the space to be vacated at the same rental rates, then upon the expiration of such leases, as well as the expiration of any future leases, we may experience a material adverse effect on our business.

Any adverse developments in the economic or regulatory environment of our four markets, Northern Virginia; suburban Chicago, Illinois; Santa Clara, California; and Toronto, Ontario, may materially adversely affect our business and operating results.

Our portfolio of operating data center facilities is located in only three markets - Northern Virginia, Chicago, and Santa Clara, California and we plan to open a new data center facility in the Toronto, Ontario metropolitan area later this year. Consequently, we may be exposed to greater economic risks than if our portfolio was more geographically diverse. Also, we may be susceptible to adverse developments in the economic and regulatory environment in any of these markets, including, but not limited to, business layoffs or downsizing, industry slowdowns, relocations of businesses, increases in real estate and other taxes and costs of complying with existing or increased governmental regulation. In addition, other markets in the United States could become more attractive for developers, operators and customers of data center facilities based on favorable costs to construct or operate data center facilities in such other markets. For example, some states have created tax and other incentives for developers and operators to locate data center facilities in their jurisdictions. Any adverse developments in the economy or real estate market in general, or any decrease in demand for data center space resulting from adverse developments in the regulatory or business environment in Northern Virginia, Chicago, Santa Clara, California or Toronto, Ontario could materially adversely impact our business, results of operations and financial condition.

Our long-term growth depends upon the successful development of our data centers, and unexpected costs or changes in permit requirements or environmental regulations may delay or preclude the construction of additional data centers, thereby materially adversely affecting our business, results of operations and financial condition.

16

For any future data center developments, we will be subject to certain risks that could result in a delay in completion of a project, including, but not limited to, risks related to the acquisition of real property, financing, zoning, environmental and other regulatory approvals, and construction costs. Any delay or denial of a required entitlement or permit, including zoning, land use, environmental, emissions or other related permits would adversely impact our plans for future development. Changes to any applicable regulations, including changes to air quality standards or emissions limitations, could delay or preclude our ability to construct additional data centers or operate our data center facilities, which such delay or preclusion would have a material adverse effect on our growth and future results of operations and financial condition. In addition, we intend to develop properties in new geographic regions, such as the Toronto, Ontario and Portland, Oregon metropolitan areas, where we do not possess the same level of familiarity with the development of properties as we do in our existing metropolitan areas, which could adversely affect our ability to develop such properties in a timely manner or at all, or within budgeted costs.

We also will be subject to risks and, potentially, unanticipated costs associated with obtaining access to a sufficient amount of power from local utilities, including costs associated with the development of utility substations on our properties, if applicable, in order to accommodate our power needs, constraints on the amount of electricity that a particular locality's power grid is capable of providing at any given time, and risks associated with the negotiation of long-term power contracts with utility providers. We may not be able to successfully negotiate such contracts on acceptable terms or at all. Any inability to negotiate utility contracts on a timely basis or on acceptable financial terms or upon terms that provide utility power in amounts sufficient to supply the critical load presently anticipated for each of our development properties would have a material adverse effect on our growth, future results of operations and financial condition.

In addition, the selection and acquisition of sites suitable for data center development is a critical factor in our expansion plans. We have limited inventory of facilities with phases available for future development and undeveloped land held for development. There may not be suitable properties available in our markets with the necessary combination of high power capacity and fiber connectivity, or selection of such sites may be limited. For instance, it may not always be possible to locate new data center facilities adjacent to our existing locations, which is our preference. Any inability to acquire additional sites for development, at all or on terms acceptable to us, could have a material adverse effect on our growth, future results of operations and financial condition.

We generally commence development of a data center facility prior to having received any commitments from customers to lease any space in the facility and any extended vacancies could have a material adverse effect on our business, results of operations and financial condition.

We generally commence development of a data center facility prior to having received any commitments from customers to lease any space in them - commonly known as developing “on speculation” - as, for example, we have done with the development of ACC9, CH3 and TOR1, which currently are under construction. This type of development exposes us to the risk that we will be unable to attract customers on a timely basis, or at all, to the properties that we have developed. This risk may be greater in a market where we have not operated previously, such as Toronto, Ontario, where the first phase of a data center facility is under construction. Once development of a data center facility is complete, we incur certain operating expenses even if there are no customers occupying any space. Consequently, if any of our properties have significant vacancies for an extended period of time, we will incur operating expenses that will not be reimbursed by customers and our results of operations and business and financial condition will be affected adversely, the impact of which could be material.

The loss of access to key third-party technical service providers and suppliers could materially adversely affect our current and any future development projects.

Our success depends, to a significant degree, on having timely access to certain key technical personnel who are in limited supply and considerable demand, such as engineering firms and construction contractors capable of developing our properties, and on having timely access to key suppliers of electrical and mechanical equipment utilized in the design of our data center facilities. For any future wholesale data center development projects, we will continue to rely on these personnel and suppliers. The demand for such technical expertise is intense, and there are a limited number of electrical and mechanical equipment suppliers that design and produce the equipment that we require. We may not always have or retain access to the key service providers and equipment suppliers that we rely on, which could materially adversely affect our current and future development projects.

17

We are dependent upon third-party suppliers for power and diesel fuel for our backup engine generators, 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 requirements of our facilities' infrastructure and our customers' servers and computer equipment, we may be unable to satisfy our obligations to our customers. In addition, the utility companies that provide electricity to our data centers are susceptible to power shortages and planned or unplanned power outages caused by these shortages. If the duration of such an outage were to exceed the time that the fuel stored on-site can power our backup engine generators (as can occur during a severe weather event, such as a hurricane, or other natural disaster), we would be dependent on the regular delivery of diesel fuel to our affected sites. If we are not able to operate any of our data centers with our backup engine generators during an outage, our customers, reputation and business would be harmed.

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 susceptible to price increases of, a particular type of fuel, such as coal, oil or natural gas. 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.

We depend on third parties to provide Internet connectivity to the customers in our data centers and any delays or disruptions in connectivity may materially adversely affect our business, results of operations and financial condition.

Our customers require connectivity to the fiber networks of multiple third party telecommunication carriers and we depend upon the presence of telecommunication carriers' fiber networks serving the locations of our data centers in order to attract and retain customers. Any carrier may elect not to offer its services within our data centers, and any carrier that has decided to provide Internet connectivity to our data centers may discontinue the provision of Internet connectivity to our data centers. If carriers were to consolidate or otherwise downsize or terminate connectivity within our data centers, such action could have an adverse effect on the businesses of our customers and, in turn, our own business, financial condition and results of operations.

Each new data center that we develop requires the 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. If we are not able to establish adequate Internet connectivity to our data centers, such connectivity is materially delayed or is discontinued, or there are significant hardware or fiber failures on this network, our ability to attract and retain new customers or retain existing customers could be impacted negatively, which in turn could have a material adverse effect on our business, financial condition and results of operations.

Failure to abide by applicable service level commitments could subject us to material liability under the terms of our leases, which could materially adversely affect our business, results of operations and financial condition.

Our leases generally include terms requiring us to meet certain service level commitments primarily in terms of electrical output to, and maintenance of environmental conditions within, the computing rooms leased by customers. Any failure to meet these commitments, including as a result of mechanical failure, power outage, including the inability of utilities that serve our data center facilities to deliver electricity, human error on our part or for other reasons, could subject us to liability under our leases, including the loss of management fee reimbursements or the abatement of rent or, in certain cases of repeated failures, could give the customer a right to terminate the lease. Any such failures also could materially adversely affect our reputation and adversely impact our ability to lease our properties. Each of these impacts could have a material adverse effect on our business, financial condition and results of operations.

We may be vulnerable to security breaches which could disrupt our operations and have a material adverse effect on our business, results of operations and financial condition.

A security breach could result in the misappropriation of our proprietary information and cause interruptions or malfunctions in our operations, which in turn could interrupt the operations of our customers. We may be required to expend significant financial resources to protect against such threats or to alleviate problems caused by security breaches. We may not be able to implement 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 business, financial condition and results of operations.

18

Certain of our leases include restrictions on the sale of our properties to certain third parties, which could have a material adverse effect on us, including our business, results of operations and financial condition.

Certain of our leases give the customer a right of first refusal to purchase certain properties if we propose to sell those properties to a third party or prohibit us from selling certain properties to a third party that is a competitor of the customer. The existence of such restrictions could hinder our ability to sell one or more of these properties, which could materially adversely affect our business, financial condition and results of operations.

The bankruptcy or insolvency of a major customer would have a material adverse impact on us, including our business, results of operations and financial condition.

The bankruptcy or insolvency of a major customer as we experienced in 2015 with Net Data Centers would materially adversely affect our business and the income produced by our properties. If any customer becomes a debtor in a case under the U.S. Bankruptcy Code, we cannot evict the customer solely because of the bankruptcy. In addition, the bankruptcy court might authorize the customer to reject and terminate its lease with us. Our claim against the customer for unpaid future rent would be subject to a statutory cap that might be substantially less than the remaining rent owed under the lease. In either case, our claim for unpaid rent would likely not be paid in full. Our business, including our revenue and cash available for distribution to our stockholders, could be materially adversely affected if any of our significant customers were to become bankrupt or insolvent, suffer a downturn in its business, or fail to renew its lease at all or renew on terms less favorable to us than its current terms.

Future consolidation in the technology industry could materially adversely affect our business, results of operations and financial condition by eliminating some of our potential customers and could make us more dependent on a more limited number of customers.

Mergers or consolidations of technology companies in the future could reduce the number of our customers and potential customers. If our customers merge with or are acquired by other entities that are not our customers, 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 business, results of operations and financial condition.

Changes in customer requirements for data center facilities could have a material adverse effect on our business, results of operations and financial condition.

The data center market is characterized by evolving industry standards and changing customer requirements. Some of our customers operate at significant scale across numerous data center facilities and have designed cloud and computing networks with redundancies and fail-over capabilities across these facilities, which enhances the resiliency of their networks and applications. This enhanced resiliency may cause customers to re-evaluate their requirements for an individual data center’s electrical or mechanical infrastructure redundancy. As a result, these customers may realize cost benefits by locating their data center operations in facilities with less redundancy than is found in our existing data center facilities. Additionally, some of our customers have begun to operate their data centers using direct outside air, with a wider range of humidity levels and at temperatures that are higher than servers customarily have operated at in the past, all of which may result in energy cost savings for these customers. We may not be able to operate our existing data centers under these environmental conditions, particularly in multi-tenant facilities with other customers who are not willing to operate under these conditions. If these trends result in changes to the preferences of our large-scale customers, our data center facilities could be at a competitive disadvantage to facilities that satisfy the requirements of these customers. Because we may not be able to modify the redundancy levels or environmental systems of our existing data centers economically, these or other changes in customer requirements could have a material adverse effect on our business, results of operations and financial condition.

Our operating properties are not suitable for use other than as data centers, which could make it difficult to reposition them if we are not able to lease available space and could materially adversely affect our business, results of operations and financial condition.

Our data centers are designed solely to house and run computer servers and related equipment and, therefore, contain extensive electrical and mechanical systems and infrastructure. As a result, they are not suitable for use by customers as anything other than as data centers and major renovations and expenditures would be required in order for us to re-lease vacant space for more traditional uses, or for us to sell a property to a buyer for use other than as a data center.

Declining real estate valuations could result in impairment charges, the determination of which involves a significant amount of judgment on our part. Any impairment charge would materially adversely affect our business, results of operations and financial condition.

19

We review our properties for impairment on a quarterly basis and whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Other indicators of impairment include, but are not limited to, a sustained significant decrease in the market price of or the cash flows expected to be derived from a property. A significant amount of judgment is involved in determining the presence of an indicator of impairment. If the total of the expected undiscounted future cash flows is less than the carrying amount of a property, an impairment loss is recognized for the difference between the fair value and carrying value of the property. The evaluation of anticipated cash flows requires a significant amount of judgment regarding assumptions that could differ materially from actual results in future periods, including assumptions regarding estimated remaining life of the data center, future occupancy, rental rates and capital requirements. Any impairment charge would materially adversely affect our business, financial condition and results of operations.

Any losses to our properties that are not covered by insurance, or that exceed our policy coverage limits, would materially adversely affect our business, results of operations and financial condition.

We carry comprehensive liability, fire, earthquake, extended coverage, business interruption and rental loss insurance covering all of the properties in our portfolio, which includes coverage for riots, terrorism, acts of God and floods that are subject to policy specifications and insured limits. 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. In addition, some of our policies, like those covering losses due to floods, are subject to limitations involving large deductibles or co-payments and policy limits that may not be sufficient to cover potential losses. If we experience a loss that is uninsured or 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 property is subject to recourse indebtedness, such as is the case with respect to ACC3, we would continue to be liable for the indebtedness, even if these properties were irreparably damaged. These events would materially adversely affect our business, financial condition and results of operations.

We could become subject to liability for failure to comply with environmental and other laws and regulations, including international laws and regulations.

We are subject to environmental laws and regulations regarding the handling of regulated substances and wastes, including, in particular, regulations regarding the storage of petroleum for auxiliary or emergency power. The properties in our portfolio are also subject to various federal, state and local laws and regulations, including those related to: air quality and exhaust emissions; discharges of treated storm water; and health, safety and fire (See “Business - Regulation - Environmental Matters”).

In addition, we are subject to environmental, health and safety laws regulating air emissions, storm water management and other issues arising in our business. Unexpected events, equipment malfunctions and human error, among other factors, can lead to violations of environmental laws, regulations or permits. Furthermore, environmental laws and regulations change frequently and may require additional investment to maintain compliance. Noncompliance with existing, or adoption of more stringent, environmental or health and safety laws and regulations or the discovery of previously unknown contamination could require us to incur costs or become the basis of new or increased liabilities that could be material.

If we or our customers fail to comply with these various requirements, we might incur governmental fines or other sanctions or private damage awards. Moreover, existing requirements could change and future requirements could require us to make significant unanticipated expenditures that will materially adversely impact our business, results of operations and financial condition.

In addition, compliance with international and U.S. laws and regulations that apply to our international operations increases our cost of doing business in foreign jurisdictions. These laws and regulations include data privacy requirements, labor relations laws, tax laws, anti-competition regulations, import and trade restrictions, export requirements, economic and trade sanctions, U.S. laws such as the Foreign Corrupt Practices Act and local laws which also prohibit bribery payments to governmental officials. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our offerings in one or more countries, could delay or prevent potential acquisitions, and could also materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, our business and our operating results.

We may be adversely affected by laws, regulations or other issues related to climate change.

If we, or other companies with which we do business, particularly utilities that provide our facilities with electricity, become subject to laws or regulations related to climate change, our business, results of operations and financial condition could be impacted adversely. In addition, if our customers adopt programs or policies to increase their utilization of energy

20

from renewable sources, and the utilities that provide our facilities with electricity cannot satisfy these customers’ requirements for renewable sources of energy, our business, results of operations and financial condition could be impacted adversely.

The federal government and some of the states and localities in which we operate have enacted certain climate change laws and regulations and/or have begun regulating carbon footprints and greenhouse gas emissions. Although these laws and regulations have not had any known material adverse effects on our business to date, they could limit our ability to develop new facilities or result in substantial compliance costs, retrofit costs and construction costs, including monitoring and reporting costs and capital expenditures for environmental control facilities and other new equipment. Furthermore, our reputation could be negatively affected if we violate climate change laws or regulations.

We cannot predict how future laws and regulations, or future interpretations of current laws and regulations, related to climate change will affect our business, results of operations and financial condition. For instance, utilities that serve our data center facilities may be impacted by clean air regulations that have been proposed by the U.S. Environmental Protection Agency. These regulations, if finalized, would require states to reduce carbon emitted by power generation facilities by specified dates. As a result of these regulations, the cost to generate or procure electricity by any of the utilities that serve our data center facilities could increase significantly. If utilities that provide electricity to our data center facilities cannot generate or procure electricity from renewable sources, at all or at competitive rates, our current and prospective customers may seek to locate their respective data center operations in markets served by utility providers that are able to generate or procure electricity from renewable sources at competitive rates.

Lastly, the potential physical impacts of climate change on our operations are highly uncertain, and would be particular to the geographic circumstances in each area in which we operate. These impacts may be caused by changes in rainfall and storm patterns and intensities, water shortages, changing sea levels and changing temperatures. The impacts on our operations caused by these changes may adversely impact our business, results of operations and financial condition.

Our expansion into new markets may present increased risks due to our unfamiliarity with those areas.

In November 2015, we announced that, over the next several years, we plan to expand our data center development and operations into one or more new markets. As a part of this expansion strategy, we may be developing and operating data centers in markets in which we have little or no operating experience. Our ability to successfully enter new markets will depend on, among other things, our ability to find and acquire land suitable for development, our ability to develop new data centers on our anticipated time-line and at the expected cost, and our ability to lease up newly developed data centers.  Our new markets may have different competitive conditions, and may subject us to different operating considerations, than those we have experienced in our existing markets, which, in turn, may adversely affect our ability to develop and operate data centers in these new markets.

Expansion of our business into new markets will involve substantial planning and allocation of significant company resources and certain risks, including risks related to financing, zoning, regulatory approvals, construction costs and delays. Our lack of operating experience in these new markets may adversely impact our ability to successfully develop new data center facilities in such markets.  In order for our prospective data center development projects in these new markets to be successful, we will be required to carefully select and rely on the experience of one or more general contractors and associated subcontractors during the data center construction process, some of which we may have little or no experience working with. Should a general contractor or significant subcontractor working on any such development project experience financial or other material problems during the construction process, we could experience significant delays, increased costs to complete the project and other issues that may negatively impact our expected financial returns. As we expand into new markets, Site selection in expansion markets is also a factor critical to our expansion plans, and there may not be available, or our lack of operating experience in a new market may make it difficult for us to successfully identify and acquire, suitable properties in these markets in locations that are attractive to our customers and that have access to multiple network providers and a significant supply of electrical power. These and other risks could result in delays to, or increased costs of, completing development projects in new markets or could prevent the completion of development projects in new markets, any of which could have a material adverse effect on our business, financial condition and results of operations.

In addition, expansion into new markets will subject us to risks, including unanticipated costs, associated with obtaining access to a sufficient amount of power from local utilities with whom we have little or no experience, including risks and costs related to the need, in some cases, to develop utility substations on our properties in order to accommodate our power needs; risks related to constraints on the amount of electricity that a particular locality’s power grid is capable of providing at any given time, and risks and costs associated with the negotiation of long-term power contracts with unfamiliar utility providers. We cannot assure you that we will be able to successfully negotiate such contracts on acceptable terms or at all. Any inability to negotiate utility contracts on a timely basis or on acceptable financial terms or in volumes sufficient to supply the requisite

21

power for our development properties would have a material adverse effect on our growth and results of operations and financial condition.

We generally commence development of a data center facility prior to having received any commitments from customers to lease any space in them - commonly known as developing “on speculation” - and we expect to develop data centers in new markets “on speculation” as well. Due to our lack of operating experience in our new markets, we may be unable to attract customers on a timely basis, or at all, to the properties that we have developed. Once development of a data center facility is complete, we incur certain operating expenses even if there are no customers occupying any space. Consequently, if any of our properties have significant vacancies for an extended period of time, we will incur operating expenses that will not be reimbursed by customers and our results of operations and business and financial condition will be affected adversely, the impact of which could be material.

If we are unable to successfully develop, lease up and operate data centers in new markets, our ability to implement our business strategy and our financial condition and results of operations may be materially adversely affected.

As with the development of our other data centers, the development of data centers in new markets is subject to certain risks that could result in a delay in completion or the failure to complete the project, including, but not limited to, risks related to financing, zoning, environmental and other regulatory approvals, and construction costs. We cannot assure you that we will be able to successfully develop a data center or that we will be able to lease up our data centers once they are developed. If we are unable to successfully develop a data center on the land that we own in Hillsboro, Oregon or the Greater Toronto Area or in any of the other planned expansion markets, our ability to implement our business strategy may be adversely affected, which, in turn, could have a material adverse effect on our financial condition and results of operation.

Fluctuations in foreign currency exchange rates in the markets in which we operate internationally could harm our results of operations.

We may experience gains and losses resulting from fluctuations in the foreign currency exchange rate of the Canadian Dollar relative to the U.S. Dollar. To date, all of our revenues and costs have been denominated in U.S. dollars. With the development of our TOR1 data center facility in the Toronto, Ontario metropolitan area, we will be exposed to risks resulting from fluctuations in the Canadian Dollar exchange rate in connection with TOR1-related operations. The majority of the construction costs and operating expenses related to TOR1 will be paid in Canadian Dollars, which could result in these costs and expenses being more than anticipated as a result of declines in the U.S. Dollar relative to the Canadian Dollar. Similarly, we expect that our TOR1 customers will pay rent to us in Canadian Dollars, which could result in these revenues being less than anticipated as a result of increases in the U.S. Dollar relative to the Canadian Dollar. In addition, fluctuating foreign currency exchange rates will impact how our international results of operations translate into U.S. Dollars.

Despite using Canadian-denominated debt to hedge portions of our net investment in our Canadian-denominated assets, we likely will not be able to eliminate all foreign currency transaction exposure. In addition, REIT compliance rules may restrict our ability to enter into derivative hedging transactions in the future. If the U.S. Dollar strengthens relative to the Canadian Dollar, our consolidated financial position and results of operations may be negatively impacted as these Canadian Dollar amounts will translate into fewer U.S. Dollars. For additional information on foreign currency risk, refer to our discussion of foreign currency risk in “Quantitative and Qualitative Disclosures About Market Risk” included in Item 7A of this Annual Report on Form 10-K.

Derivative transactions may limit our gains or result in material losses.

We may use derivatives to hedge our foreign currency or interest rate risks from time to time, although, as of December 31, 2016, we had no derivative transaction in place. Any derivative transactions into which we enter could expose us to certain risks, including:

• losses on a hedge position reducing the cash available for distribution to stockholders and such losses exceeding the amount invested in such instruments;

• counterparties to a hedging arrangement defaulting on their obligations;

• paying certain fees, such as transaction or brokerage fees; and

• incurring costs if we elect to terminate a hedging agreement early.

The REIT rules impose certain restrictions on our ability to utilize swaps and other types of derivatives to hedge our risks. As a result of these rules, we may have to limit our use of derivative hedging techniques that might otherwise be advantageous or implement those hedges through a taxable REIT subsidiary. This could increase the cost of our hedging activities because our taxable REIT subsidiary would be subject to tax on gains or expose us to greater risks associated with changes in interest or

22

foreign currency rates than we would otherwise want to bear. In addition, losses in our taxable REIT subsidiary will generally not provide any tax benefit, except for being carried back or forward against past or future taxable income in the taxable REIT subsidiary. However, hedges may not be effective in eliminating all of the risks inherent in any particular position. Our profitability may be materially adversely affected during any period as a result of the use of such derivatives.

Our success is dependent on access to qualified personnel. Our inability to recruit or retain qualified personnel, or the loss of any of our key personnel, including our executive officers or senior employees, could adversely affect our business, financial condition and results of operations.

Our success will continue on depend to access to qualified personnel. We must continue to identify, hire, train and retain IT professionals, technical engineers, operations employees, and sales, marketing, finance and senior management personnel who maintain relationships with our customers and who can provide the technical, strategic and marketing skills required for our company to grow. We compete with other companies, including many of our competitors, for the limited pool of talent in these fields. Also, each of our executive officers has an industry reputation that attracts business and investment opportunities and assists us in negotiations with lenders, existing and potential customers and industry personnel. The loss of key employees could hinder our ability to continue to benefit from existing and potential customers. We cannot provide any assurance that we will be able to retain our current executive officers or key employees. The failure to recruit and retain necessary personnel, including, but not limited to, members of our executive team, could harm our business and our ability to grow our company, and could adversely affect our business, financial condition and results of operations.

If we fail to maintain an effective system of integrated internal controls, we may not be able to accurately and timely report our financial results.

If we fail to maintain proper overall business controls, our results of operations could be materially adversely affected or we could fail to meet our reporting obligations, including the accurate and timely reporting of our financial results. In addition, the existence of a material weakness could result in errors in our consolidated financial statements that could require a restatement of our consolidated financial statements, cause us to fail to meet our reporting obligations and cause investors to lose confidence in our reported financial information, leading to, among other things, a decline in the market value of our common stock.

Our cash distributions are not guaranteed and may fluctuate.

Although a REIT generally is required to distribute at least 90% of its REIT taxable income to its stockholders, taxable income varies significantly from year-to-year, and also varies significantly from, and can be significantly less than, net income under GAAP.

Our Board of Directors determines on a quarterly basis the amount of cash to be distributed to our stockholders based on a number of factors including, but not limited to, our REIT taxable income, results of operations, cash flow, capital and liquidity requirements, economic conditions, tax considerations, borrowing capacity and other factors, including debt covenant restrictions that may impose limitations on cash payments, future acquisitions and divestitures and any stock repurchase program. Consequently, our distribution levels may fluctuate from period-to-period.

Risks Related to Our Debt and Preferred and Common Stock Financings

We depend on external sources of capital to fund our growth and refinance existing indebtedness, which capital may not be available to us at all or on terms favorable or acceptable to us.

The cash that we used for the development of data center facilities and the payment of dividends on our preferred and common stock exceeded the cash provided by our operating activities in each year from 2008 through 2016. Our operating activities are not expected to generate sufficient cash to provide the capital necessary for all of our capital requirements including the construction of the ACC9, CH3 and TOR1 data center facilities, and the third phase of the SC1 data center facility, the development of the land that we hold for future data center development, the expansion into new markets and the repayment of our existing indebtedness. In addition, as a REIT, DFT is required under the Internal Revenue Code of 1986, as amended (the “Code”) to distribute at least 90% of its “REIT taxable income,” excluding any net capital gain, to its stockholders annually. Consequently, we rely on third-party sources of capital to fund our development projects and refinance our existing indebtedness. Our access to capital depends, in part, on:

• general business conditions;

• financial market conditions;

• the market's perception of our business prospects and growth potential;

• our current debt levels;

• our current and expected earnings and cash flow; and

23

• the market price of our common stock.

There is no assurance that we will be able to obtain equity or debt financing at all or on terms favorable or acceptable to us. If we are unable to obtain capital from third parties, we may need to find alternative ways to increase our liquidity, which may include curtailing development activity or disposing of one or more of our properties possibly on disadvantageous terms.

Fluctuations in interest rates could materially affect our financial results.

As of December 31, 2016, $412.2 million of our total consolidated indebtedness (approximately 33% of total consolidated indebtedness) was subject to variable interest rates. We also may incur additional variable rate debt in the future. Because a significant portion of our debt 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.

Adverse changes in our credit ratings could negatively affect our financing activity.

The credit ratings of our senior unsecured long-term debt and DFT’s preferred stock are based on our 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 credit ratings can affect the amount of capital we can access, as well as the terms and pricing of any debt we may incur and preferred securities that we may issue. We cannot assure you that we will be able to maintain our current credit ratings. 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 credit ratings would cause an increase in interest rates under our existing term loans and unsecured line of credit, and may trigger other additional payments or other negative consequences under our current and future credit facilities and debt instruments. 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 our common and preferred stock, and DFT's development and acquisition activity.

We have outstanding indebtedness and preferred stock, which requires that we generate significant cash flow to satisfy the payment and other obligations under the terms of our debt and these securities, and exposes us to the risk of default under the terms of our debt and these securities.

As of December 31, 2016, our total consolidated indebtedness was $1.26 billion, which exceeds the total of our cash on hand at December 31, 2016 and our annual cash flows from operating activities for 2016. Since December 31, 2016, we have incurred an additional $107.1 million of indebtedness, increasing our total indebtedness to $1.37 billion as of the date of this filing. As of December 31, 2016, we also had outstanding $201.3 million of Series C Preferred Stock. We may incur additional debt or issue additional preferred stock for various purposes, including, without limitation, to fund future acquisitions and development activities and operational needs.

The terms of our outstanding indebtedness, as of December 31, 2016, and preferred stock provide for significant interest and dividend payments in 2017, including:

• $60.6 million of interest on our outstanding indebtedness, based on current interest rates; and

• $13.3 million of preferred stock dividends.

Our ability to meet these and other ongoing payment obligations of our debt and preferred stock depends on our ability to generate significant cash flow in the future. Our ability to generate cash flow, to some extent, is subject to general economic, financial, competitive, legislative and regulatory factors, as well as other factors that are beyond our control. We cannot assure you that our business will generate cash flow from operations, or that capital will be available to us, in amounts sufficient to enable us to meet our payment obligations under our senior notes, our credit agreements and our outstanding preferred stock and to fund our other liquidity needs. If we are not able to generate sufficient cash flow to service these obligations, we may need to refinance or restructure our debt, sell assets (which we may be limited in doing in light of the relatively illiquid nature of our properties), reduce or delay capital investments, or seek to raise additional capital. If we are unable to implement one or more of these alternatives, we may not be able to meet these payment obligations, which could materially and adversely affect our liquidity.

Our outstanding indebtedness, and the limitations imposed on us by the agreements that govern our outstanding indebtedness, and the fixed charge obligations under our outstanding preferred stock, could have significant adverse consequences, including the following:

24

• make it more difficult for us to satisfy our obligations;

• limit our ability to obtain additional financing to fund future working capital, capital expenditures and other general corporate requirements, or to carry out other aspects of our business plan;

• limit our ability to refinance our indebtedness at maturity or impose refinancing terms that may be less favorable than the terms of the original indebtedness;

• require us to dedicate a substantial portion of our cash flow from operations to payments on obligations under our outstanding indebtedness and preferred stock, thereby reducing the availability of such cash flow to fund working capital, capital expenditures and other general corporate requirements, or adversely affect our ability to meet REIT distribution requirements imposed by the Code;

• cause us to violate restrictive covenants in the documents that govern our indebtedness, which would entitle our lenders to accelerate our debt obligations;

• cause us to default on our obligations, causing lenders or mortgagees to foreclose on properties that secure our loans and receive an assignment of our rents and leases;

• force us to dispose of one or more of our properties, possibly on unfavorable terms or in violation of certain covenants to which we may be subject; and

• limit our ability to make material acquisitions or take advantage of business opportunities that may arise and limit our flexibility in planning for, or reacting to, changes in our business and industry, thereby limiting our ability to compete effectively or operate successfully.

If any one of these events was to occur, our business, results of operations and financial condition would be materially adversely affected.

The documents that govern our outstanding indebtedness restrict our ability to engage in some business activities, which could materially adversely affect our business, results of operations and financial condition.

The documents that govern our outstanding indebtedness contain customary negative covenants and other financial and operating covenants that place restrictions on DFT, the Operating Partnership and their respective subsidiaries. These covenants restrict, among other things, the ability of DFT, the Operating Partnership and their respective subsidiaries to:

• incur debt and liens;

• enter into sale and leaseback transactions;

• make certain dividend payments, distributions and investments;

• enter into transactions with affiliates;

• enter into agreements limiting the Operating Partnership's ability to make certain transfers and other payments from subsidiaries;

• sell assets; and

• merge or consolidate.

In addition, covenants contained in the documents that govern our outstanding indebtedness require the Operating Partnership and/or its subsidiaries to meet certain financial performance tests.

These restrictive operational and financial covenants will reduce our flexibility in conducting our operations, limit our flexibility in planning for, or reacting to, changes in our business and industry, and limit our ability to engage in activities that may be in our long-term best interest, including the ability to make acquisitions or take advantage of other business opportunities that may arise, any of which could materially adversely affect our growth prospects, future operating results and financial condition.

Our failure to comply with these restrictive covenants could result in an event of default that, if not cured or waived, could result in the acceleration of all or a substantial portion of our outstanding debt (which might also cause cross-defaults with respect to our other debt obligations). For a detailed description of the covenants and restrictions imposed by the documents governing our indebtedness, see “Management's Discussion and Analysis of Financial Condition and Results of Operations - Outstanding Indebtedness.”

The documents that govern our outstanding indebtedness require that we maintain certain financial ratios and, if we fail to do so, we would be in default under the applicable debt instrument, which in turn could trigger defaults under our other debt instruments, which could result in the maturities of all of our debt obligations being accelerated and would have a material adverse effect on us, including our business, results of operations and financial condition.

Each of our debt instruments requires that we maintain certain financial ratios. The credit agreement that is secured by our ACC3 data center facility provides that the total indebtedness of the Operating Partnership and its subsidiaries cannot exceed 60% of the value of the assets of the Operating Partnership and its subsidiaries, determined based on the appraised value

25

of stabilized data center properties, the amount of unrestricted cash and the book value of development properties and undeveloped land. Under this credit agreement, the administrative agent periodically has the right to have each of our stabilized data center properties appraised. If the total indebtedness of the Operating Partnership exceeds 60% of the applicable asset value, the indebtedness in question would have to be reduced to a level that resulted in compliance with this ratio.

The credit agreements that govern our unsecured term loan and unsecured revolving credit facility each require that we maintain financial ratios relating to the following matters: (i) unsecured debt not exceeding 60% of the value of unencumbered assets; (ii) net operating income generated from unencumbered properties divided by the amount of unsecured debt being not less than 12.5%; (iii) total indebtedness not exceeding 60% of gross asset value; (iv) fixed charge coverage ratio being not less than 1.70 to 1.00; and (v) tangible net worth being not less than $2.3 billion plus 75% of the sum of (x) net equity offering proceeds and (y) the value of equity interests issued in connection with a contribution of assets to the Operating Partnership or its subsidiaries.

In addition, the indentures that govern our senior notes require, among other things, that the Operating Partnership and our subsidiaries that guaranty the notes maintain total unencumbered assets of at least 150% of their unsecured debt on a consolidated basis.

If we do not continue to satisfy these covenant ratios, we will be in default under the applicable debt instrument, which in turn would trigger defaults under our other debt instruments, which could result in the maturities of all of our debt obligations being accelerated. These events would have a material adverse effect on our liquidity.

The terms of the agreements that govern our indebtedness limit our ability to sell the data center properties that have been pledged as collateral for our indebtedness, which could reduce our liquidity.

One of our income producing data center properties - ACC3 - serves as collateral under an existing credit agreement. This credit agreement limits our ability to sell this property. The indenture that governs our senior notes and the credit agreements that govern our unsecured term loan and unsecured revolving credit facility limit our ability to sell or transfer assets and, under certain circumstances, the indenture requires that we use any net cash proceeds to reduce outstanding indebtedness. Consequently, our ability to raise capital through the disposition of assets is limited.

Indebtedness secured by our properties exposes us to the possibility of foreclosure, which could result in the loss of the property that secures the indebtedness and any rents to which we would be entitled from leases on that property.

The obligations under one of our credit agreements, with an outstanding principal balance at December 31, 2016 of $111.3 million, is secured by our ACC3 data center facility. A default of any of the obligations under this credit agreement could result in foreclosure actions by our lenders and the loss of the property securing the indebtedness and an assignment to the lenders of our rents and leases related to any such property.

For tax purposes, a foreclosure of any such property would be treated as a sale of the property for a purchase price equal to the outstanding balance of the underlying indebtedness. If the outstanding balance of this debt exceeds our tax basis in the property, we would recognize taxable income on foreclosure, but would not receive any cash proceeds from the disposition of the property.

In the future, we may assume or incur additional indebtedness secured by one or more properties that we own or in connection with property acquisitions.

Disruptions in the financial markets may materially and adversely affect our ability to secure additional financing.

The U.S. stock and credit markets have experienced significant price volatility, dislocations and liquidity disruptions in the past, which have caused market prices of many stocks to fluctuate substantially, led some lenders and institutional investors to reduce, and in some cases cease, to provide credit to businesses and has caused spreads on prospective debt financings to widen considerably. Renewed uncertainty in these markets, or any downturn, could affect our ability to obtain debt financing, or to refinance our debt, at all or on terms favorable or acceptable to us. Such events also may make it more difficult or costly for us to raise capital through the issuance of our common stock or preferred stock. Our inability to secure additional financing may impede our ability to initiate new development projects. Disruptions in the financial markets could have a material adverse effect on us, including our business, results of operations and our financial condition.

We may be unable to satisfy our debt obligations upon a change of control of us.

Under the documents that govern our indebtedness, if we experience a change of control, we could be required to repay the entire principal balance of our outstanding indebtedness. Under our senior notes indentures, if we experience a change of control, as defined in the indenture, we must offer to purchase the notes at 101% of their principal amount, plus accrued

26

interest. Under the credit agreements that govern our term loans and unsecured revolving credit facility, if we experience a change of control, as defined in the applicable credit agreement, we must repay the principal amount of any outstanding loans, plus accrued interest, and, in the case of our unsecured revolving credit facility, the obligation of the lenders to fund any additional loans would terminate. We might not have sufficient funds to repay the amounts due under the term loans or the unsecured revolving credit facility or pay the required price for the notes following a change of control. Any of these events could have a material adverse impact on our liquidity, business, results of operations and financial condition.

Risks Related to the Real Estate Industry

Our performance and value are subject to risks associated with real estate assets and with the real estate industry.

Real estate investments are subject to various risks and fluctuations and cycles in value and demand, many of which are beyond our control. Certain events and conditions may decrease our cash available for distribution, as well as the value of our properties. These events include, but are not limited to, the following:

• inability to collect rent from customers;

• vacancies or our inability to rent space on favorable terms, including possible market pressures to offer customers rent abatements, customer improvements, early termination rights or below market renewal options;

• adverse changes in financial conditions of buyers, sellers and customers of properties, including data centers;

• the attractiveness of our properties to customers;

• competition from other real estate investors with significant resources and access to capital, including other real estate operating companies, publicly traded REITs and institutional investment funds;

• reductions in the level of demand or increase in the supply for data center space;

• inability to acquire land for new data center development;

• inability to finance development on favorable terms;

• fluctuations in interest rates, which could adversely affect our ability, or the ability of buyers and customers of properties, including data centers, to obtain financing on favorable terms or at all;

• increases in expenses that are not paid for by or cannot be passed on to our customers;

• changes to, and enforcement of, laws, regulations and governmental policies, and the costs of compliance therewith;

• civil unrest, acts of war, terrorist attacks and natural disasters, including earthquakes, tornados, hurricanes and floods, which may result in uninsured and underinsured losses; and

• the relative illiquidity of real estate investments, especially the specialized real estate properties that we hold and seek to acquire and develop.

Illiquidity of real estate investments and the terms of certain of our leases could significantly impede our ability to respond to adverse changes in the performance of our properties, which could materially adversely affect our business, results of operations and financial condition.

Because real estate investments are relatively illiquid, our ability to promptly sell one or more properties in our portfolio to raise cash in response to adverse changes in the performance of such properties may be limited and thus could materially adversely affect our financial condition.

In addition, data centers represent an illiquid part of the overall real estate market, due to the relatively small number of potential purchasers of such data centers - including other data center operators and large corporate users - and the relatively high cost per square foot to develop data centers, which limits a potential buyer's ability to purchase a data center property with the intention of redeveloping it for an alternative use, such as an office building, or may substantially reduce the price buyers are willing to pay for the property.

As the present or former owner or operator of real property, we could become subject to liability for environmental contamination, regardless of whether we caused such contamination, which could have a materially adverse effect on our business, results of operations and financial condition.

Under various federal, state and local laws, regulations and ordinances that relate to the protection of the environment, a current or former owner, operator or customer of real property may be liable for the cost to remove or remediate contamination resulting from the presence or discharge of hazardous or toxic substances, wastes or petroleum products on, under, from or in such property. These costs could be substantial and liability under these laws may attach 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. Previous owners of the sites where some of our data center facilities are located (CH1, CH2 and SC1), and the undeveloped land for our ACC8 and ACC11 facilities, used these sites for industrial or retail purposes. As a result, these properties may contain some level of environmental contamination (See “Business - Regulation - Environmental Matters”). In addition, many

27

of our properties presently contain large underground fuel storage tanks for emergency power, which are critical to our operations. We likely would be liable for contamination that results from a release of fuel from any of these storage tanks. Moreover, the presence of contamination or the failure to remediate contamination at our properties may expose us to third-party liability, which liabilities may be material, or materially adversely affect our ability to sell, lease or develop the contaminated property or to borrow capital using the contaminated property as collateral for the loan.

As the owner of real property, we could become subject to liability for asbestos-containing building materials in the buildings on our property, which could have a materially adverse effect on our business, results of operations and financial condition.

Some of our properties may contain asbestos-containing building materials. Environmental laws require that owners or operators of buildings with asbestos-containing building materials properly manage and maintain these materials, adequately inform or train those who may come into contact with asbestos and undertake special precautions, including removal or other abatement, in the event that asbestos is disturbed during building renovation or demolition. These laws may impose fines and penalties on building owners or operators for failure to comply with these requirements. In addition, 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 may contain or develop harmful mold or suffer from other adverse conditions, which could lead to liability for adverse health effects and costs of remediation.

When excessive moisture accumulates in buildings or on building materials, mold growth may occur, 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 other biological contaminants such as pollen, viruses and bacteria. Indoor exposure to airborne toxins or irritants above certain levels may 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 customers, employees of our customers and others if property damage or health concerns arise.

We may incur significant costs complying with the Americans with Disabilities Act, or ADA, and similar laws, which could materially adversely affect our business, results of operations and financial condition.

Under the ADA, all places of public accommodation must meet federal requirements related to access and use by disabled persons. A number of additional federal, state and local laws may also require modifications to our properties. We have not conducted an audit or investigation of all of our properties to determine our compliance with the ADA. If one of our properties is not in compliance with the ADA, we would be required to incur additional costs to bring the property into compliance. Additional federal, state and local laws may require modifications to our properties, or restrict our ability to renovate our properties. We cannot predict the ultimate amount of the cost of compliance with the ADA or other laws. If we incur substantial costs to comply with the ADA and any other similar laws, our business, financial condition and results of operations could be materially adversely affected.

We may incur significant costs complying with other regulations, which could materially adversely affect our business, results of operations and financial condition.

The properties in our portfolio are subject to various federal, state and local regulatory requirements. If we fail to comply with these requirements, we might incur governmental fines or private damage awards. In addition, we do not know whether existing requirements will change or whether future requirements will require us to make significant unanticipated expenditures that could materially adversely affect our business, results of operations and financial condition.

Risks Related to Our Organizational Structure

Conflicts of interest exist or could arise in the future with holders of units of partnership interest in the Operating Partnership, or OP units, which may impede business decisions that could benefit DFT's stockholders.

Conflicts of interest exist or could arise in the future as a result of the relationships between DFT and its affiliates, on the one hand, and the Operating Partnership or any of its partners, on the other. DFT's directors and officers have duties to DFT and its stockholders under applicable Maryland law. At the same time, DFT, as general partner, has fiduciary duties to the Operating Partnership and to its limited partners under Maryland law. DFT's duties as general partner to the Operating Partnership and its partners may come into conflict with the duties of DFT's directors and officers to DFT and its stockholders. The partnership

28

agreement of the Operating Partnership provides that as long as DFT is the general partner of the Operating Partnership, any conflict that cannot be resolved in a manner not adverse to either DFT's stockholders or the limited partners will be resolved in favor of DFT's stockholders.

Additionally, the partnership agreement expressly limits DFT's liability by providing that DFT and its officers, directors, agents and employees, will not be liable or accountable to the Operating Partnership for losses sustained, liabilities incurred or benefits not derived if DFT, or such officer, director, agent or employee acted in good faith. In addition, the Operating Partnership is required to indemnify DFT, and its officers, directors, employees, agents and designees to the extent permitted by applicable law from and against any and all claims arising from operations of the Operating Partnership, unless it is established that (1) the act or omission was committed in bad faith, was fraudulent or was the result of active and deliberate dishonesty, (2) the indemnified party received an improper personal benefit in money, property or services or (3) in the case of a criminal proceeding, the indemnified person had reasonable cause to believe that the act or omission was unlawful. The provisions of Maryland law that allow the fiduciary duties of a general partner to be modified by a partnership agreement have not been resolved 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 DFT's fiduciary duties that would be in effect were it not for the partnership agreement.

DFT is also subject to the following additional conflicts of interest with holders of OP units:

DFT may pursue less vigorous enforcement of terms of the employment agreement with Mr. du Pont because of DFT's dependence on him and conflicts of interest. Mr. du Pont entered into an employment agreement with DFT, including clauses prohibiting him from competing with DFT, subject to certain exceptions, in the data center market. This agreement was not negotiated on an arm's length basis. DFT may choose not to enforce, or to enforce less vigorously, its rights under this employment agreement because of its desire to maintain its ongoing relationship with Mr. du Pont and because of conflicts of interest with him, including allowing him to devote significant time to non-data center projects outside of the Company, to engage in activities that may compete with DFT, or to engage in transactions with DFT without receiving the appropriate board approval.

Tax consequences upon sale or refinancing. Sales of properties, substantially all of our assets and our company, a merger or consolidation of our company, and repayment of related indebtedness will have different effects on holders of OP units than on DFT's stockholders. The parties that contributed properties to the Operating Partnership may incur tax consequences upon the sale of these properties, substantially all of our assets or our company, a merger or consolidation of our company, and on the repayment of related debt which differ from the tax consequences to DFT and its stockholders. Consequently, these holders of OP units may have different objectives regarding the appropriate pricing and timing of any such transaction or repayment of debt. Although DFT has exclusive authority as general partner under the partnership agreement of the Operating Partnership to determine when to refinance or repay debt or whether, when, and on what terms to sell a property, substantially all of our assets or our company, or enter into a merger or consolidation of our company, any such decision would require the approval of DFT's board of directors, and DFT's ability to take such actions, to the extent that they may reduce the liabilities of the Operating Partnership, may be limited pursuant to the tax protection agreements that DFT entered into upon completion of its initial public offering. Certain of DFT's directors and executive officers could exercise their influence in a manner inconsistent with the interests of some, or a majority, of its stockholders, including in a manner which could delay or prevent completion of a sale of a property or the repayment of indebtedness.

Mr. du Pont has the right to hold a significant percentage of DFT's stock. DFT's charter generally authorizes its directors to take such actions as are necessary and desirable to preserve DFT's qualification as a REIT and to limit any person (other than a qualified institutional investor) to actual or constructive ownership of no more than 3.3% of the outstanding shares of its common stock by value or by number of shares, whichever is more restrictive and 3.3% of its outstanding capital stock by value. DFT's board of directors, however, has granted, and in the future may grant, exemptions from the ownership limits described above if such exemptions do not jeopardize its status as a REIT. In addition, DFT's charter provides that Mr. du Pont, certain of his affiliates, family members and trusts formed for the benefit of the foregoing, may own up to 20.0% of the outstanding shares of DFT's common stock by value or by number of shares, whichever is more restrictive, and 20.0% of DFT's outstanding capital stock by value. In addition, pursuant to Mr. du Pont’s employment agreement, if he holds at least 9.8% of our outstanding shares on a fully diluted basis, he will have a contractual right to be nominated to the board of directors. These exemptions and contractual rights could allow Mr. du Pont to exercise a substantial degree of control over DFT's affairs even if he is no longer an executive officer.

Mr. du Pont has significant influence over our affairs. As of December 31, 2016, Mr. du Pont owned an aggregate of approximately 0.2% of DFT's common stock and approximately 25.5% of the OP units (not including those units held by DFT), equal to approximately 4.0% of DFT's common stock, on a fully diluted basis. As a result, he could have influence over our affairs and could exercise such influence in a manner that is not in the best interests of DFT's other stockholders, including by

29

attempting to delay, defer or prevent a change in control transaction that might otherwise be in the best interests of DFT's stockholders. If he exercises his redemption rights with respect to his OP units and DFT issues common stock in exchange thereof, his influence over our affairs would increase substantially.

DFT's charter and Maryland law contain provisions that may delay, defer or prevent a change in control transaction, even if such a change in control may be in DFT's stockholders' interest, and as a result may depress our stock price.

DFT's charter contains a 3.3% ownership limit. DFT's charter, subject to certain exceptions, authorizes its directors to take such actions as are necessary and desirable to ensure DFT's qualification as a REIT and to limit any person (other than a qualified institutional investor or an excepted holder) to actual or constructive ownership of no more than 3.3% of the outstanding shares of its common stock by value or by number of shares, whichever is more restrictive, and 3.3% of its outstanding capital stock by value. This ownership limit may delay, defer or prevent a transaction or a change in control that might involve a premium price for DFT's common stock or otherwise be in the best interest of its stockholders.

DFT could increase the number of authorized shares of stock and issue stock without stockholder approval. DFT's charter authorizes its board of directors, without stockholder approval, to increase 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 DFT's common stock or preferred stock and to classify or reclassify any unissued shares of its common stock or preferred stock and to set the preferences, rights and other terms of such classified or unclassified shares. DFT's board of directors could establish a series of preferred stock that could, depending on the terms of such series, delay, defer or prevent a transaction or a change in control that might involve a premium price for its common stock or otherwise be in the best interest of its stockholders.

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 inhibiting a third party from making a proposal to acquire us or of impeding a change in control under circumstances that otherwise could provide the holders of shares of our common stock with the opportunity to realize a premium over the then-prevailing market price of such shares, including:

• “business combination” provisions that, subject to limitations, prohibit certain business combinations between us and an “interested stockholder” (defined generally as any person who beneficially owns 10% or more of the voting power of our shares or an affiliate or associate of ours who, at any time within the two-year period prior to the date in question, was the beneficial owner of 10% or more of our then outstanding voting shares) 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 special stockholder voting requirements on these combinations; and

• “control share” provisions that provide that “control shares” of our company (defined as shares which, when aggregated with other shares controlled by the stockholder, 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 “control shares”) have no voting rights except to the extent approved by our 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.

DFT 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 by a provision in its bylaws. However, DFT's board of directors may by resolution elect to opt in to the business combination provisions of the MGCL and it may, by amendment to its bylaws (which such amendment could be adopted by its board of directors in its sole discretion), opt in to the control share provisions of the MGCL in the future.

The provisions of DFT's charter on removal of directors and the advance notice provisions of its bylaws could delay, defer or prevent a transaction or a change in control of our company that might involve a premium price for holders of DFT's common stock or otherwise be in their best interest. Likewise, if DFT's board of directors were to opt in to the business combination provisions of the MGCL, or if the provision in DFT's bylaws opting out of the control share acquisition provisions of the MGCL were rescinded, these provisions could have similar anti-takeover effects. Further, the partnership agreement provides that DFT may not engage in any merger, consolidation or other combination with or into another person, sale of all or substantially all of our assets or any reclassification or any recapitalization or change in outstanding shares of our common stock, unless in connection with such transaction DFT obtains the consent of holders of at least 50% of the OP units of the Operating Partnership (not including OP units held by DFT) and/or certain other conditions are met.

Certain provisions in the partnership agreement of the Operating Partnership may delay or prevent unsolicited acquisitions of us. Provisions in the partnership agreement of the Operating Partnership may delay or make more difficult unsolicited acquisitions of us or changes in our control. These provisions could discourage third parties from making proposals

30

involving an unsolicited acquisition of us or change of our control, although some stockholders might consider such proposals, if made, desirable. These provisions include, among others:

• redemption rights of qualifying parties;

• transfer restrictions on the OP units;

• DFT's ability, as general partner, in some cases, to amend the partnership agreement without the consent of the limited partners; and

• the right of the limited partners to consent to transfers of the general partnership interest and mergers under specified circumstances.

DFT's rights and the rights of its stockholders to take action against its directors and officers are limited.

Maryland law provides that a director or officer has no liability in that capacity if he or she performs his or her duties in good faith, in a manner he or she reasonably believes to be in our 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, DFT's charter limits the liability of its directors and officers to DFT 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, DFT's charter authorizes DFT to obligate our company, and DFT's bylaws require DFT, to indemnify its directors and officers for actions taken by them in those capacities to the maximum extent permitted by Maryland law. As a result, DFT and its stockholders 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 our directors or officers impede the performance of our company, stockholders' ability to recover damages from such director or officer will be limited.

Future offerings of debt or equity securities, which would be senior to our common stock upon liquidation and for the purpose of distributions, may cause the market price of our common stock to decline.

In the future, we may attempt to increase our capital resources by making additional offerings of debt or equity securities, including commercial paper, medium-term notes, senior or subordinated notes and classes of preferred stock or common stock. We will be able to issue additional shares of common stock or preferred stock without stockholder approval, unless stockholder approval is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. Upon liquidation, holders of our debt securities and shares of preferred stock and lenders with respect to other borrowings will receive a distribution of our available assets prior to the holders of our common stock. Additional equity offerings may dilute the holdings of our existing stockholders or reduce the market price of our common stock, or both. Holders of our common stock are not entitled to preemptive rights or other protections against dilution. As data center acquisition or development opportunities arise from time to time, we may issue additional shares of common stock or preferred stock to raise the capital necessary to finance these acquisitions or developments or may issue common stock or preferred stock or OP units, which are redeemable for, at our option, cash or our common stock on a one-to-one basis, to acquire such properties. Such issuances could result in dilution of stockholders' equity. Preferred stock and debt, if issued, could have a preference on liquidating distributions or a preference on dividend or interest payments that could limit our ability to make a distribution to the holders of our common stock. Because our decision to issue securities in any future offering or acquisition will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our stockholders bear the risk of our future offerings reducing the market price of our common stock and diluting their interest.

Risks Related to Our Status as a REIT

Failure to qualify as a REIT would have significant adverse consequences to us and the value of our stock.

We believe that we have qualified as a real estate investment trust, or REIT, for federal income tax purposes and we intend to continue to meet the requirements for qualification and taxation as a REIT, but we cannot assure shareholders that we will qualify as a REIT. Requirements under the Code for qualification and taxation as a REIT are extremely complex and interpretations of the federal income tax laws governing qualification and taxation as a REIT are limited. 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 DFT, holds its assets through a partnership. The determination of various factual matters and circumstances not entirely within our control may affect DFT's ability to qualify as a REIT. In order to continue to qualify as a REIT, DFT must satisfy a number of requirements, including requirements regarding the composition of its assets, the sources of its income and the diversity of its stock ownership. Also, DFT must make distributions to stockholders aggregating annually at least 90% of its “REIT taxable income,” determined before the deduction for dividends paid and excluding net capital gains. Furthermore,

31

any new laws, Treasury regulations, interpretations, or court decisions could change the federal income tax laws or the federal income tax consequences of DFT's qualification and taxation as a REIT. As a result, no assurance can be provided that DFT will continue to qualify as a REIT or that new legislation, Treasury regulations, administrative interpretations or court decisions will not significantly change the federal income tax laws with respect to, or the federal income tax consequences of, DFT's qualification and taxation as a REIT.

If DFT were to lose its REIT status, the tax consequences could reduce its cash available for distribution to its stockholders substantially for each of the years involved because:

• DFT 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;

• DFT could be subject to the federal alternative minimum tax and increased state and local taxes; and

• Unless DFT is entitled to relief under applicable statutory provisions, DFT could not elect to be taxed as a REIT for four taxable years following the year during which it was disqualified.

The additional tax liability to us for the year or years in which DFT does not qualify as a REIT would reduce our net earnings available for investment, debt service or distribution to DFT's stockholders. Furthermore, if DFT were to fail to qualify as a REIT, non-U.S. stockholders that own more than 10% of any class of DFT's shares, who otherwise might not be subject to federal income tax on the sale of DFT's shares, could be subject to federal income tax with respect to any gain on a net basis similar to the taxation of a U.S. stockholder. In addition, if DFT were to fail to qualify as a REIT, DFT would not be required to make distributions to stockholders, and all distributions to stockholders would be subject to tax as ordinary dividend income to the extent of its current and accumulated earnings and profits. As a result of all these factors, DFT's failure to qualify as a REIT also could impair our ability to expand our business and raise capital, and could materially adversely affect the value of DFT's stock.

Failure to qualify as a domestically-controlled REIT could subject DFT's non-U.S. stockholders to adverse federal income tax consequences.

DFT will be a domestically-controlled REIT if, at all times during a specified testing period, less than 50% in value of its shares of stock is held directly or indirectly by non-U.S. stockholders. Because its shares of stock are publicly traded, DFT cannot guarantee that it will, in fact, be a domestically-controlled REIT. If DFT fails to qualify as a domestically-controlled REIT, its non-U.S. stockholders that otherwise would not be subject to federal income tax on the gain attributable to a sale of DFT's shares of stock would be subject to taxation upon such a sale if either (a) the shares of stock were not considered to be “regularly traded” under applicable Treasury regulations on an established securities market, such as the NYSE, or (b) the shares of stock were considered to be “regularly traded” on an established securities market and the selling non-U.S. stockholder owned, actually or constructively, more than 10% in value of the outstanding shares of common stock at any time during specified testing periods. If gain on the sale or exchange of DFT's shares of stock was subject to taxation for these reasons, the non-U.S. stockholder would be subject to federal income tax with respect to any gain on a net basis in a manner similar to the taxation of a taxable U.S. stockholder, subject to any applicable alternative minimum tax and special alternative minimum tax in the case of nonresident alien individuals, and corporate non-U.S. stockholders may be subject to an additional branch profits tax.

If the structural components of our properties were not treated as real property for purposes of the REIT qualification requirements, DFT would fail to qualify as a REIT.

A significant portion of the value of our properties is attributable to structural components related to the provision of electricity, heating ventilation and air conditioning, humidification regulation, security and fire protection, and telecommunication services. We have received a private letter ruling from the Internal Revenue Service (the “IRS”) holding, among other things, that our buildings, including the structural components, constitute real property for purposes of the REIT qualification requirements. We are entitled to rely upon that private letter ruling only to the extent that we did not misstate or omit a material fact in the ruling request we submitted to the IRS and that we operate in the future in accordance with the material facts described in that request. Moreover, the IRS, in its sole discretion, may revoke the private letter ruling. If our structural components are determined not to constitute real property for purposes of the REIT qualification requirements, including as a result of our being unable to rely upon the private letter ruling or the IRS revoking that ruling, DFT would fail to qualify as a REIT, which could have a material adverse impact on the value of DFT's stock.

32

If the Operating Partnership failed to qualify as a partnership for federal income tax purposes, DFT would fail to qualify as a REIT and suffer other adverse consequences.

We believe that the Operating Partnership is organized and operated in a manner so as to be treated as a partnership, and not an association or publicly traded partnership taxable as a corporation, for federal income tax purposes. As a partnership, it is not subject to federal income tax on its income. Instead, each of its partners, including DFT, is allocated that partner's share of the Operating Partnership's income. No assurance can be provided, however, that the IRS will not challenge the Operating Partnership's status as a partnership for federal income tax purposes, or that a court would not sustain such a challenge. If the IRS were successful in treating the Operating Partnership as an association or publicly traded partnership taxable as a corporation for federal income tax purposes, DFT would fail to meet the gross income tests and certain of the asset tests applicable to REITs and, accordingly, would cease to qualify as a REIT. Also, the failure of the Operating Partnership to qualify as a partnership would cause it to become subject to federal corporate income tax, which would reduce significantly the amount of its cash available for debt service and for distribution to its partners, including DFT.

DFT will be subject to some taxes even if it qualifies as a REIT.

Even if DFT qualifies as a REIT for federal income tax purposes, it is subject to some federal, state and local taxes on its income and property. For example, DFT is subject to federal income tax on certain types of income that it does not distribute. In addition, if assessed, DFT would incur a 100% excise tax on transactions with its taxable REIT subsidiary, or TRS, that are not conducted on an arm's length basis. A TRS is a corporation which is owned, directly or indirectly, by DFT and which, together with DFT, makes an election to be treated as our TRS. In addition, our TRS is subject to federal income tax as a corporation on its taxable income, if any, which consists of the revenues mainly derived from providing technical services, on a contract basis, to our customers. The after-tax net income of our TRS is available for distribution to us but is not required to be distributed.

Moreover, if DFT has net income from “prohibited transactions,” that income will be subject to a 100% tax. In general, prohibited transactions are sales or other dispositions of property held primarily for sale to customers in the ordinary course of business. The determination as to whether a particular sale is a prohibited transaction depends on the facts and circumstances related to that sale.

We will have a reduced carryover tax basis on certain of our assets as a result of the formation transactions, which could reduce our depreciation deductions.

Some of our operating properties have a carryover tax basis that is lower than the fair market value of the property. This position could give rise to lower depreciation deductions on these assets that would have the effect of (1) increasing the distribution requirement imposed on us, which could materially adversely affect our ability to satisfy the REIT distribution requirement, and (2) decreasing the extent to which our distributions are treated as tax-free “return of capital” distributions.

Our tax protection agreements could limit our ability to sell or otherwise dispose of certain properties.

In connection with our formation transactions and October 2007 initial public offering, we entered into tax protection agreements with a number of limited partners of the Operating Partnership, including Mr. du Pont and certain of our directors. The agreements provide that, if we dispose of any interest in ACC2, ACC3, ACC4, VA3, VA4 or CH1 in a taxable transaction through the year 2017, we will indemnify these partners for their tax liabilities (in varying amounts, depending on the year in which the disposition occurs) attributable to the built-in gain that exists with respect to such property interest as of the time of our October 2007 initial public offering (and tax liabilities incurred as a result of the reimbursement payment) if those tax liabilities exceed a certain amount. Consequently, although it otherwise may be in our best interest to sell one of these properties, these obligations may make it prohibitive for us to do so. In addition, any such sale must be approved by at least 75% of our disinterested directors. Additionally, the agreement contains various provisions to achieve minimum liability allocations to certain limited partners and indemnifies them for their tax liabilities resulting from any gain or income recognized due to breach of those provisions by the Operating Partnership.

Complying with the REIT requirements may cause us to forgo and/or liquidate otherwise attractive investments.

To qualify as a REIT, we must continually satisfy tests concerning, among other things, the sources of our income, the nature and diversification of our assets, the amounts that we distribute to our shareholders and the ownership of our shares. To meet these tests, we may be required to take or forgo taking actions that we would otherwise consider advantageous. For instance, in order to satisfy the gross income or asset tests applicable to REITs under the Code, we may be required to forgo investments that we otherwise would make. Furthermore, we may be required to liquidate from our portfolio otherwise attractive investments. In addition, we may be required to make distributions to shareholders at disadvantageous times or when

33

we do not have funds readily available for distribution. These actions could reduce our income and amounts available for distribution to our shareholders. Thus, compliance with the REIT requirements may hinder our investment performance.

Changes in taxation of corporate dividends may adversely affect the value of ourstock.

The maximum marginal rate of tax payable by domestic noncorporate taxpayers on dividends received from a regular “C” corporation under current federal law is generally lower than the marginal rates at which ordinary income is taxed. The reduced tax rate, however, does not apply to distributions paid to domestic noncorporate taxpayers by a REIT on its stock, subject to certain exceptions. The earnings of a REIT that are distributed to its stockholders generally remain subject to less federal income taxation than earnings of a non-REIT “C” corporation that are distributed to its stockholders net of corporate-level income tax. However, the lower rate of taxation on dividends paid by regular “C” corporations could cause domestic noncorporate investors to view the stock of regular “C” corporations as more attractive relative to the stock of a REIT, because the dividends from regular “C” corporations continue to be taxed at a lower rate while distributions from REITs (subject to certain exceptions) are generally taxed at the same rate as other ordinary income for domestic noncorporate taxpayers.

There is a risk of changes in the tax law applicable to REITs.

The IRS, the United States Treasury Department and Congress frequently review federal income tax legislation, regulations and other guidance. Legislative and regulatory changes, including comprehensive tax reform, may be more likely in the 115th Congress, which convened in January 2017, because the Presidency and both Houses of Congress will be controlled by the same political party. We cannot predict whether, when or to what extent new federal tax laws, regulations, interpretations or rulings will be adopted. Any legislative action may prospectively or retroactively modify our tax treatment and, therefore, may adversely affect taxation of us and/or our investors.

PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Market Price of and Dividends on the Registrant's Common Equity

Shares of DFT's common stock, par value $.001 per share (“common stock”) trade on the New York Stock Exchange (“NYSE”) under the symbol “DFT.” As of February 1, 2017, DFT had less than 100 holders of record of its common stock. This figure does not reflect the beneficial ownership of shares held in nominee name. The following table sets forth, for the indicated periods, the high and low sale prices for DFT's common stock on the NYSE and the cash distributions declared per share:

	Price Range				Cash Distribution Declared Per Share
	High		Low
2016
First Quarter	$	41.14	$	28.83	$	0.47
Second Quarter	$	47.54	$	39.35	$	0.47
Third Quarter	$	48.97	$	41.20	$	0.47
Fourth Quarter	$	44.38	$	37.54	$	0.50
2015
First Quarter	$	38.30	$	30.43	$	0.42
Second Quarter	$	33.42	$	29.06	$	0.42
Third Quarter	$	30.81	$	24.88	$	0.42
Fourth Quarter	$	33.62	$	25.60	$	0.47

To qualify and maintain its qualification as a REIT, DFT intends to make annual distributions to its stockholders of at least 90% of its "REIT taxable income" (which does not equal net income as calculated in accordance with generally accepted accounting principles). Dividends are declared by the board of directors. DFT's ability to pay dividends to its stockholders is dependent on the receipt of distributions from the Operating Partnership, which in turn is dependent on its data center properties generating operating income. The indentures that govern our 5.875% senior unsecured notes due 2021 (the “Unsecured Notes due 2021”) and our 5.625% senior unsecured notes due 2023(the “Unsecured Notes due 2023”) limit our ability to pay dividends, but allow us to pay the minimum necessary to meet DFT's REIT income distribution requirements.

Issuer Purchases of Equity Securities

During the year ended December 31, 2016, we did not repurchase any of our registered equity securities under a stock repurchase program. We have a 2017 common stock repurchase program that allows for purchases up to $100.0 million through December 31, 2017. As of February 23, 2017, we did not repurchase any of our registered equity securities under this program.

Unregistered Sales of Equity Securities

DFT, from time to time, issues common shares pursuant to its equity compensation plans, when stock options are exercised and pursuant to redemptions by the limited partners of the Operating Partnership of common units of limited partnership interest. Pursuant to the Partnership Agreement, each time DFT issues common shares as described above, the Operating Partnership issues to DFT, its general partner, an equal number of units for the same price at which the common shares were sold, in transactions that are not registered under the Securities Act of 1933, as amended (the "Securities Act") in reliance on Section 4(2) of the Securities Act due to the fact that common units were issued only to DFT and therefore, did not involve a public offering. During the year ended December 31, 2016, the Operating Partnership issued 2,324,211 common units to DFT in connection with such redemptions, stock option exercises and issuances pursuant to DFT's equity compensation plans, for $75.6 million.

Performance Graph

The following line graph sets forth, for the period from December 31, 2011 through December 31, 2016, a comparison of the percentage change in the cumulative total stockholder return on DFT's common stock compared to the cumulative total

35

return of the S&P 500 Index, the Russell 2000 Index and the FTSE National Association of Real Estate Investment Trusts Equity REIT Index. The graph assumes that $100 was invested on December 31, 2011 in shares of our common stock and each of the aforementioned indices and that all dividends were reinvested without the payment of any commissions. There can be no assurance that the performance of our common stock will continue in line with the same or similar trends depicted in the graph below.

The foregoing graph shall not be deemed incorporated by reference by any general statement incorporating by reference this Annual Report on Form 10-K into any filing under the Securities Act, as amended, or under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), except to the extent the Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under those acts.

(1) Funds from operations, or FFO, is used by industry analysts and investors as a supplemental operating performance measure for REITs. We calculate FFO in accordance with the definition that was adopted by the Board of Governors of the National Association of Real Estate Investment Trusts, or NAREIT. FFO, as defined by NAREIT, represents net income determined in accordance with GAAP, excluding extraordinary items as defined under GAAP, impairment charges on depreciable real estate assets and gains or losses from sales of previously depreciated operating real estate assets, plus specified non-cash items, such as real estate asset depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. We also present FFO attributable to common shares and OP units, which is FFO excluding preferred stock dividends. FFO attributable to common shares and OP units per share is calculated on a basis consistent with net income attributable to common shares and OP units and reflects adjustments to net income for preferred stock dividends.

We use 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 period over period, captures trends in occupancy rates, rental rates and operating expenses. We also believe that, as a widely recognized measure of the performance of equity REITs, FFO may be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes real estate-related 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

39

of our properties, all of which have real economic effects and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited.

While FFO is a relevant and widely used measure of operating performance of equity REITs, other equity REITs may use different methodologies for calculating FFO and, accordingly, FFO as disclosed by such other REITs may not be comparable to our FFO. Therefore, we believe that in order to facilitate a clear understanding of our historical operating results, FFO should be examined in conjunction with net income as presented in the consolidated statements of operations. FFO should not be considered as an alternative to net income or to cash flow from operating activities (each as computed in accordance with GAAP) or as an indicator of our liquidity, nor is it indicative of funds available to meet our cash needs, including our ability to pay dividends or make distributions.

We present FFO with adjustments to arrive at Normalized FFO. Normalized FFO is FFO attributable to common shares and units excluding severance expense and equity accelerations, gain or loss on early extinguishment of debt, gain or loss on derivative instruments and write-offs of original issuance costs for redeemed preferred shares. We also present FFO with supplemental adjustments to arrive at Adjusted FFO (“AFFO”). AFFO is Normalized FFO excluding straight-line revenue, compensation paid with Company common shares, below market lease amortization and write-offs net of above market lease amortization and write-offs, non real estate depreciation and amortization, amortization of deferred financing costs, improvements to real estate and capitalized leasing commissions. AFFO does not represent cash generated from operating activities in accordance with GAAP and therefore should not be considered as an alternative to net income as an indicator of our operating performance or as an alternative to cash flow provided by operations as a measure of liquidity and is not necessarily indicative of funds available to fund our cash needs including our ability to pay dividends. In addition, AFFO may not be comparable to similarly titled measurements employed by other companies. We use AFFO in management reports to provide a measure of REIT operating performance that can be compared to other companies using AFFO.

(2) Net income for the year ended December 31, 2016 includes a gain on sale of real estate of $22.8 million, write-off of issuance costs on preferred stock of $12.5 million, loss on early extinguishment of debt of $1.2 million and severance expense and equity accelerations of $0.9 million. Net income for the year ended December 31, 2015 includes an impairment on investment in real estate of $122.5 million and severance expense and equity accelerations of $6.1 million. Net income for the years ended December 31, 2014 and 2013 includes losses on early extinguishment of debt of $1.7 million and $41.0 million, respectively.

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

Overview

DuPont Fabros Technology, Inc. (“DFT”) is a fully integrated, self-administered and self-managed real estate investment trust, or REIT, that owns, acquires, develops and operates wholesale data centers. DFT is the sole general partner of, and, as of December 31, 2016, owned 84.9% of the common economic interest in DuPont Fabros Technology, L.P. (the “Operating Partnership” or “OP”). Unless otherwise indicated or unless the context requires otherwise, all references to “we,” “us,” “our,” “our Company” or “the Company” refer to DFT and the Operating Partnership, collectively.

We design and operate innovative, multi-tenant, wholesale data centers, and create solutions with our customers that free them to focus on their core businesses. Our facilities are designed to offer highly specialized, efficient and safe computing environments in a low-cost operating model. Our customers include national and international enterprises across numerous industries, including technology, Internet, content providers, cloud providers, media, communications, healthcare and financial services. Our 11 data centers have a total of 3.3 million gross square feet and 287 megawatts of power available to our customers to operate their servers and computing equipment. For the year ended December 31, 2016, we generated $528.7 million of total revenues, net income of $181.4 million and cash provided by operating activities of $290.0 million. As of December 31, 2016, we had total assets of $3.0 billion.

Data centers are facilities that house large numbers of computer servers and related equipment and include the infrastructure necessary to operate this equipment, including systems for power distribution, environmental control, fire suppression and security. We believe that our data centers provide sufficient power to meet the needs of the world's largest technology companies. We lease the computer room square feet, or CRSF, and the available power of our facilities to customers under long-term leases. As of January 1, 2017:

• We had 32 customers with 124 different lease expirations, with only 14.2% of these expirations occurring over the next two years as measured by annualized base rent;

• The weighted average remaining term of our leases at our operating data centers was 5.4 years; and

• We served five of the Fortune 25 and 20 of the Fortune 1000, which includes private or foreign enterprises of equivalent size.

Our data centers are strategically located in three major population centers - Northern Virginia, suburban Chicago, Illinois and Santa Clara, California. We have acquired property and have plans to expand into two new markets - the greater Toronto area, and the Portland, Oregon metropolitan area. Each of our current and expansion markets has significant electrical power availability and hubs of extensive fiber network connectivity. As of December 31, 2016, we owned the following properties:

• 11 operating data centers facilities;

• Five phases of existing data center facilities under development;

• One shell of a data center currently under development;

• Two data center facilities with a phase or phases available for future development; and

• Parcels of land held for future development of four data centers.

We believe that we are well positioned to develop, lease, operate and manage our growing data center portfolio.

We derive substantially all of our revenue from rents received from customers. For most of our customers, and we believe for most potential wholesale data center customers, the amount of available power is the primary factor used to evaluate their data center requirements. Consequently, rents under our leases are based primarily on the amount of power made available to our customers, rather than the amount of space that they occupy. The term “critical load” is used to indicate that portion of each facility's total power capacity that is made available for the exclusive use of its customers to operate their computer servers. Accordingly, throughout this Form 10-K, we discuss our operations in terms of available critical load because it is one of the primary metrics that we use to manage our business. We also provide information relating to each facility's total gross building area and its computer room square feet ("CRSF"), which is the net rentable area of each of our facilities.

We also provide certain technical services to customers as a contractor on a purchase order basis, including layout design and installation of electrical power circuits, data cabling, server cabinets and racks, computer room airflow analyses and monitoring and other services requested by customers.

Business Strategy

Our goal is to diversify our customer base and improve our profitability by expanding our geographic presence and supplementing our portfolio with flexible wholesale products. We will continue to serve the wholesale segment of the data center market exclusively. We will capitalize on our exceptional skill in data center design, development and operations as we build-out our development pipeline and maximize cash flow from our existing properties. Specifically, we will expand our geographic presence; diversify our portfolio with flexible wholesale products to meet a variety of power density, redundancy and deployment needs and continue to prudently build-out our development pipeline.

Expand Our Geographic Presence. Our primary focus in the past has been to develop and lease data center space in the three markets in which we operate. Over the next several years, we plan to expand our data center development and operations into several new markets, which we believe will create opportunities to diversify our customer base and increase our profitability. We plan to target two new markets that we believe will satisfy demand of wholesale customers. Initially, we intend to focus our development efforts in the Toronto, Ontario and Portland, Oregon markets, where we believe that there will be strong demand for wholesale data centers even though the development of a wholesale market in these markets is in its infancy.

In July 2016, we purchased a 46.7 acre parcel of land in the Portland market, and in September 2016, we purchased a shell building and associated land in the Toronto market. The building in Toronto is a former Toronto Star printing facility, and the shell is well-suited for development of our TOR1 data center. We have begun development of Phase IA of TOR1 and expect to deliver this phase later in 2017.

Diversify our portfolio with flexible wholesale products to meet a variety of power density, redundancy and deployment needs. The data center requirements of prospective customers vary greatly between the Internet, cloud and technology industries, on the one hand, and enterprises, on the other. There are three key areas where customer requirements vary:

• Power Density, which is the amount of power available in a fixed amount of space. Many Internet, cloud and technology customers require “high-density” space, or a large amount of power relative to the space, while many enterprise customers require “low density” space, or a smaller amount of power relative to the space. Our more recent data center facility designs (ACC6 Phase II, ACC7, ACC9, CH2, CH3 and SC1 Phase II) provide some flexibility to meet different customers’ density requirements, but we have developed a new design that will enable us to meet a larger variety of density requirements for different customers within a single facility. This new design will be deployed in the Toronto, Ontario and Portland, Oregon markets.

• Redundancy, which means the number of additional power distribution, cooling units and back-up diesel engine generators included in a facility design to back-up units that are off-line for maintenance or due to a malfunction. Each of our current operating data center facilities are designed with “N+2” redundancy, which means that our facilities include two sets of power distribution systems and back-up diesel engine generators in addition to the number of these sets of units necessary to provide the power contracted by our customers. Our facilities also have this level of redundancy for our mechanical plants, which regulate the environment of the computer rooms leased by our customers. We believe that some customers require N+1 redundancy or less, and that a few customers may require redundancy more robust than N+2. Consequently, we have developed a new data center design that will enable us to meet diverse redundancy requirements of potential customers within a single facility. This new design will be deployed in the Toronto, Canada and Portland, Oregon markets. Additionally, our CH3 and ACC10 data centers, while based on our current design, will be developed with N+1 redundancy.

• Deployment needs, which relates to the time that it takes to construct a phase of a facility and ready it for a customer’s operations. Although we generally commence development of a data center facility prior to having received any commitments from customers to lease any space in the facility - commonly known as developing “on speculation” - we have found that customers often need data center space within very specific, and often short, time frames. Although our current data center development time lines allow for rapid deployment of computer room space, we have completed a new design that we believe will improve our development times and allow us to meet specific customer requirements for available computer room space.

Continue to prudently build-out our development pipeline. We determine when to develop data center properties based on the amount of available space in our operating properties and anticipated demand for data center space in each applicable market. Our development projects as of December 31, 2016 included:

44

• ACC9 Phase I - 14.4 MW of available critical load which is 20% pre-leased as of February 23, 2017, with completion expected in the second quarter of 2017;

• ACC9 Phase II - 14.4 MW of available critical load with completion expected in the third quarter of 2017;

• SC1 Phase III - 16.0 MW of available critical load which is 100% pre-leased, with completion expected in the third quarter of 2017;

• TOR1 Phase IA - 6.0 MW of available critical load with completion expected in the third quarter of 2017;

• CH3 Phase I - 13.6 MW of available critical load with completion expected in the first quarter of 2018; and

• ACC10 shell is currently in development. Building the shell now will allow us to deliver phases I and II quicker as demand warrants.

The remaining phases of TOR1, comprising 28.5 MW, and the second phase of CH3, comprising 13.6 MW, are being held for future development. We also own parcels of land available to develop four additional data centers, two of which are in the Ashburn, Virginia market and the other two are in the Portland, Oregon market.

(1) Represents 32 customers with 124 lease expiration dates. One additional customer has executed a pre-lease at ACC9 and will be our 33rd customer.

(2) CRSF is that portion of gross building area where customers locate their computer servers. One MW is equal to 1,000 kW.

(3) Annualized base rent represents the monthly contractual base rent (defined as cash base rent before abatements) multiplied by 12 for commenced leases as of January 1, 2017.

(4) A customer at ACC4 whose lease expires on July 31, 2017 has informed us that they do not intend to renew this lease. This lease is for 1.14 MW and 5,400 CRSF. Additionally, a customer at ACC6, whose lease expires on August 31, 2017, has informed us that they do not intend to renew this lease. This lease is for 0.54 MW and 2,523 CRSF. These leases total 0.9% of Annualized Base Rent. We are marketing these computer rooms for re-lease.

As of January 1, 2017, our operating property portfolio had 32 data center customers with 124 lease expiration dates. As of January 1, 2017, as described below, we had leases with our largest customer that have 29 lease expiration dates ranging from December 31, 2017 to September 30, 2031, with various renewal rights and, with respect to six lease expiration dates, an option to terminate the lease prior to the expiration date. Also, as discussed below, as of January 1, 2017, we had leases with our second largest customer that have 17 lease expiration dates ranging from June 30, 2018 to February 28, 2023, with various renewal rights and, with respect to its ACC5 lease, an option to decrease the term of the lease of each of nine of its existing computer rooms, provided the aggregate reduction in lease term does not exceed 67 months, or an average of approximately seven months per computer room.

Some leases with certain other customers include options to terminate leases prior to the expiration date. For instance, as of January 1, 2017, we had commenced leases with our third largest customer in three of our data centers with 12 expiration dates ranging from September 30, 2021 to June 30, 2022. This customer has an option to renew the term of each of these lease expiration dates for five years. With respect to six of these lease expiration dates, this customer has the option to make a termination payment and terminate these leases on September 30, 2018. These leases are shown as expiring in 2018 in the Lease Expiration Table above. Also, as of January 1, 2017, we had commenced leases with our fourth largest customer in three of our data centers with nine expiration dates ranging from June 30, 2024 to December 31, 2033. This customer has the option to renew the term of each of these lease expiration dates for five years. With respect to six of its lease expiration dates, this customer has the option to make a termination payment and terminate these leases after ten years of the respective lease terms with expiration dates ranging from June 30, 2019 to May 31, 2024. These lease expiration dates are shown as expiring after ten years in the Lease Expiration Table above. In addition, as of January 1, 2017, we had commenced leases with our fifth largest customer in four of our data centers with 12 expiration dates ranging from July 31, 2022 to March 31, 2026. This customer has

the option to renew the term of two of these lease expiration dates for between one and five years and 10 leases with an option to renew for five years. This customer has an option on ten lease expiration dates to make a termination payment and terminate the lease on dates ranging from March 31, 2018 to June 30, 2022. Two of these leases are shown as expiring March 31, 2018. Certain other customers have similar rights to terminate leases prior to their expiration dates.

Same Store Analysis

As of December 31, 2016

($ in thousands)

The following tables set forth an analysis of our same store and same store, same capital operating property portfolio for the three and twelve months ended December 31, 2016. Same store properties represent those properties placed into service on or before January 1, 2015 and owned by the Company as of December 31, 2016, include all of our operating properties except CH2, due to its first phase being placed into service in July 2015 and NJ1, due to it being sold in June 2016. Accordingly, same store properties represented 260.3 MW, or 91%, of the 287.1 MW of operating properties in service as of December 31, 2016. Same store, same capital properties represent those operating properties that were placed into service on or before January 1, 2015, that were owned by the Company as of December 31, 2016 and that have less than 10% of additional critical load developed after January 1, 2015. Accordingly, our same store, same capital properties include all of our operating properties with the exception of CH2 and NJ1, for the reasons described above, ACC7, due to Phase II of this facility being placed into service in December 2015, Phase III being placed into service in June 2016 and Phase IV being placed into service in October 2016, each of which increased the critical load of ACC7 by over 10%, and SC1, due to phase IIB of this facility being placed into service in May 2015, which increased the critical load at SC1 by over 10%. Same store, same capital properties represented 182.1 MW, or 63%, of the 287.1 MW of operating properties in service as of December 31, 2016.

(1) Net Operating Income ("NOI") represents total revenues less property operating costs, real estate taxes and insurance, and other expenses(each as reflected in the consolidated statements of operations) for the properties included in the analysis. Cash Net Operating Income ("Cash NOI") is NOI less straight-line revenues, net of reserve and amortization of lease contracts above and below market value for the properties included in the analysis.

We use NOI and Cash NOI as supplemental performance measures because, in excluding depreciation and amortization, impairment charges on depreciable real estate assets and gains and losses from property dispositions, each provides a performance measure that, when compared period over period, captures trends in occupancy rates, rental rates and operating expenses. However, because NOI and Cash NOI exclude depreciation and amortization, impairment charges on depreciable real estate assets and gains and losses from property dispositions, and capture 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 effects and could materially impact our results from operations, the utility of NOI and Cash NOI as a measure of our performance is limited.

Other REITs may not calculate NOI and Cash NOI in the same manner we do and, accordingly, our NOI and Cash NOI may not be comparable to the NOI and Cash NOI of other REITs. NOI and Cash NOI should not be considered as an alternative to operating income (as computed in accordance with GAAP).

(6) Amounts listed for gross building area, CRSF and critical load are current estimates.

Leasing

We derive substantially all of our revenue from rents received from customers under existing leases at each of our operating properties. Because we believe that critical load is the primary factor used by customers in evaluating data center requirements, rents are based primarily on the amount of power that is made available to customers, rather than the amount of space that they occupy. During 2016, we executed 14 leases totaling 50.93 MW of critical load and 267,662 CRSF of space

51

with a weighted average lease term of 12.2 years. The leases executed in 2016 are expected to generate approximately $63.3 million of annualized GAAP base rent revenue, which is equivalent to a GAAP rate of approximately $104 per kW per month. Including estimated amounts of operating expense recoveries for those leases that are structured as triple-net leases, these leases are expected to generate approximately $79.4 million of annualized GAAP revenue before recovery of metered power, which results in a GAAP rate of approximately $130 per kW per month. These leases included the following:

• Three leases at ACC7 Phase III comprising 11.52 MW of critical load and 68,408 CRSF,

• Two leases at ACC7 Phase IV comprising 4.00 MW of critical load and 21,363 CRSF,

• One pre-lease at ACC9 Phase I comprising 2.88 MW and 18,000 CRSF,

• One lease at CH2 Phase I comprising 0.58 MW, which was an increase in power related to an existing lease,

• Two leases at CH2 Phase II comprising 3.42 MW of critical load and 17,830 CRSF,

• Three leases at CH2 Phase III comprising 11.33 MW of critical load and 70,686 CRSF,

• One lease at CH2 Phase IV comprising 1.20 MW of critical load and 7,375 CRSF and

• One pre-lease at SC1 Phase III comprising the entire 16.00 MW of critical load and 64,000 CRSF of this facility.

In 2016, we also extended the terms of eight leases totaling 7.97 MW and 54,139 CRSF by a weighted average of 2.3 years. The lease terms that we extended were as follows:

• One extension at ACC4 comprising 1.14 MW of critical load and 5,400 CRSF,

• Two extensions at ACC5 comprising 3.41 MW of critical load and 16,400 CRSF,

• One extension at ACC6 comprising 0.54 MW of critical load and 2,517 CRSF,

• One extension at NJ1 comprising 0.28 MW of critical load and 1,385 CRSF and

• Three extensions at VA3 comprising 2.60 MW of critical load and 28,437 CRSF

During 2015, we executed 19 leases representing a total of 46.83 MW of critical load and 269,973 CRSF of space with a weighted average lease term of 6.6 years. We also extended the terms of seven leases totaling 12.24 MW of critical load and 69,081 CRSF by a weighted average of 3.0 years.

We generally lease space and power to our customers using a “triple net” lease structure, under which our customers occupy all or a percentage of each of our data centers and, in addition to a monthly base rent fee, are obligated to reimburse us for their share of property-level operating expenses. We also have begun to market space and power to customers under a “full service” lease structure, under which the customer's reimbursement for operating expenses is fixed with annual escalators, excluding increases to certain uncontrollable expenses. We believe the rental rates for full service leases will cover these operating expenses and will provide us with an adequate return on our investment. We signed twelve triple net leases and two full service leases in 2016. Under all of our leases, customers reimburse us for the cost of the power they use to operate their computer servers and the power that is used to cool their space. We believe that these lease structures, together with the economies of scale resulting from the size of our data centers, result in our customers paying less for power and operating expenses over time than they would in a comparable colocation setting, where power costs are often included in the license fee paid to the provider. Most of our leases provide for annual rent increases, and, as of January 1, 2017, our weighted average remaining lease term for commenced leases was approximately 5.4 years.

As of January 1, 2017, our operating property portfolio had 32 data center customers with 124 different lease expiration dates. As of January 1, 2017, our largest customer, Microsoft, accounted for 25.4% of our annualized base rent. As of January 1, 2017, we had commenced leases with Microsoft in nine of our data centers with 29 lease expiration dates ranging from December 31, 2017 to September 30, 2031 and options by Microsoft to renew six of these lease expiration dates from six months to five years, 12 expiration dates for five years and two expiration dates from one to five years. Nine of these lease expiration dates have no renewal options. In addition, Microsoft has early termination options for six of its lease expiration dates. For one expiration date, Microsoft has the right to make a termination payment and terminate this lease on either March 31, 2021 or March 31, 2026. This lease is shown as expiring in 2021 in the Lease Expiration Table. For three other expiration dates, Microsoft has the right to make a termination payment and terminate these leases on either June 30, 2026 or July 31, 2026. For two other lease expiration dates, Microsoft has the right to make a termination payment and terminate these leases on September 30, 2026. These last five expiration dates are shown as expiring in 2031 in the Lease Expiration Table after taking

52

into account the termination payment options relative to the remaining payments due under each lease. Please visit www.microsoft.com to obtain this customer's SEC filed financial information.

As of January 1, 2017, our second largest customer, Facebook, accounted for 20.2% of our annualized base rent. As of January 1, 2017, we had commenced leases with Facebook in four of our data centers with 17 lease expiration dates ranging from June 30, 2018 to February 28, 2023 and an option by Facebook to renew the term of the lease of any computer room by a duration of between 6 months and 5 years. Facebook has the right to decrease the term of the lease of each of nine of its existing computer rooms in ACC5, each with 2.28 MW of available critical load, provided the aggregate reduction in lease term does not exceed 67 months, or an average of approximately seven months per computer room.

Available Data Center Inventory and Current Development Projects

As of February 23, 2017, our operating portfolio was 99% leased and commenced as measured by CRSF and critical load. The opportunity for further revenue growth in the near term depends primarily on our ability to pre-lease space in our data center projects under development. As described above, we have 64.4 MW of available critical load under development as of February 23, 2017, which was 29% pre-leased as of February 23, 2017.

Market Conditions

Changes in the conditions of any of the markets in which our operating properties are located, including the economic conditions of a market, the financial condition of customers that procure data center space in a market, and the supply of available data center space in a market, will impact the overall performance of our current and future operating properties and our ability to fully lease our properties. The ability of our customers to fulfill their lease commitments could be impacted by future economic or regional downturns in the markets in which we operate or downturns in the industries in which our customers operate.

We take into account various factors when negotiating the terms of our leases, which can vary among leases, including the following factors: the customer’s strategic importance, growth prospects and credit quality, the length of the lease term, the amount of power leased and competitive market conditions. To determine credit quality, if a prospective customer is a publicly held entity, we evaluate its publicly filed financial statements. If a prospective customer is a privately held entity, we request audited financial statements from the customer if they exist, and unaudited financial statements if audited financial statements do not exist. We also consider any relevant news, market or industry data related to a prospective or existing customer. Furthermore, we also evaluate an existing customer's payment history with us.

We have been able to lease space and power at rates that provide a favorable return on the investment we have made in each of our operating data center facilities. There is significant competition in each of the markets in which we operate. Our primary competitors operate and are expanding their presence in our markets, and other data center providers are entering some of our markets, including the Northern Virginia market in particular. This competition could impact the rental rates adversely and, in turn, the rates of return of our investments. The rental rates of a number of leases in our portfolio that we negotiated several years ago are higher than rental rates under current market conditions. If, upon the expiration of the terms of these leases, these customers either vacate their space or negotiate the rental rates that reflect current market conditions, our rates of return would be impacted adversely. We believe that the base rents of our portfolio of operating properties in the aggregate exceed base rents that currently exist in our relevant markets. Because the terms of the leases in our portfolio expire over a weighted average period of 5.4 years as of January 1, 2017, we cannot predict how the base rents of any of our leases will compare to the market rates at the time that the terms of our leases expire. If we are unable to renew leases as their terms expire or lease vacated space with rents equal to or above historic rates, the returns on our investments we have achieved to date at our operating properties would be impacted negatively.

For the eight lease term extensions executed in 2016, which comprise 7.97 MW and 54,139 CRSF, GAAP base rent was 3.6% higher than GAAP base rent prior to the extension. Compared to the cash base rental rate in effect when these extensions were executed, cash base rent will be 3.1% higher upon commencement of the renewal lease term. For the seven lease term extensions executed in 2015, which comprise 12.24 MW of critical load and 69,081 CRSF, GAAP base rent was 4.5% higher than GAAP base rent prior to the extension. Compared to the cash base rental rate in effect when these extensions were executed, cash base rent will be 5.4% higher upon commencement of the renewal lease term.

Our taxable REIT subsidiary, DF Technical Services, LLC (the “TRS”) generates revenue by providing certain technical services to our customers on a non-recurring contract or purchase-order basis, which we refer to as “à la carte” services. Such services include the layout design and installation of electrical power circuits, data cabling, server cabinets and racks, computer room airflow analyses and monitoring and other services requested by customers. The TRS generally charges customers for these services on a cost-plus basis. Because revenue generated by the TRS varies from period to period depending on the needs of the customers for technical services, we have limited ability to forecast future revenue from this source. Moreover, as a

53

taxable corporation, the TRS is subject to federal, state and local corporate taxes and is not required to distribute its income, if any, to the Company for purposes of making additional distributions to DFT’s stockholders. However, we routinely assess the cash balance and future liquidity needs of the TRS in determining whether to distribute excess funds to the Company.

Results of Operations

This Annual Report on Form 10-K contains stand-alone audited financial statements and other financial data for each of DFT and the Operating Partnership. DFT is the sole general partner of the Operating Partnership and, as of December 31, 2016, owned 84.9% of the common economic interest in the Operating Partnership, of which approximately 0.9% is held as general partnership units. All of our operations are conducted by the Operating Partnership, which is consolidated by DFT, and therefore the following information is the same for DFT and the Operating Partnership, except that net income attributable to redeemable noncontrolling interests is not a line item in the Operating Partnership’s consolidated statement of operations.

Year Ended December 31, 2016 Compared to Year Ended December 31, 2015

Operating Revenues. Operating revenues for the year ended December 31, 2016 were $528.7 million. This includes base rent of $345.0 million, which includes a property management fee on many of our leases, customer recoveries of $169.7 million and other revenues of $14.0 million, partially from à la carte projects performed for our customers by our TRS. This compares to revenues of $452.4 million for the year ended December 31, 2015. The increase of $76.3 million, or 16.9%, was primarily due to new leases commencing at ACC7, SC1 Phase IIB and CH2, partially offset by reduced revenue from the re-lease of ACC2 at a lower rental rate and the cessation of revenue at NJ1 after it was sold in June 2016.

Operating Expenses. Operating expenses for the year ended December 31, 2016 were $316.8 million, compared to $412.8 million for the year ended December 31, 2015. The decrease of $96.0 million, or 23.3%, was primarily due to an impairment charge in 2015 of $122.5 million resulting from our decision to market NJ1 for sale. Excluding the impairment charge, operating expenses increased $26.5 million, or 9.1%, primarily due to the following: $24.0 million of increased operating costs primarily resulting from a full year of operations at SC1 Phase IIB opening in May 2015, CH2 Phase I opening in July 2015, ACC7 Phase II opening in December 2015 and a partial year of operations at ACC7 Phases III-IV and CH2 Phases II-IV in 2016; a $3.7 million increase in depreciation and amortization from the data center openings noted above; and a $5.0 million increase in general and administrative expense primarily due to increases in payroll and professional expenses related to our strategic initiatives of entering two new markets and diversifying our product offerings. Partially offsetting these increases were a partial year of operating costs at NJ1 as it was sold in June 2016, a $5.1 million decrease in other expenses primarily due to lower severance costs and charges related to the acceleration of equity awards primarily related to the departure of our former chief executive officer in February 2015 and a $1.2 million decrease in real estate taxes and insurance primarily due to the sale of NJ1 in June 2016.

Interest Expense. Interest expense, including amortization of deferred financing costs, for the year ended December 31, 2016 was $52.0 million compared to interest expense of $43.7 million for the year ended December 31, 2015. Total interest incurred for the year ended December 31, 2016 was $63.0 million, of which $11.0 million was capitalized, as compared to $56.0 million for 2015, of which $12.3 million was capitalized. The increase in total interest incurred period over period was primarily due to higher debt outstanding to finance our development projects and an increase in our average interest rate, which resulted from the issuance of $250 million of the Unsecured Notes due 2023 in June 2015 and an increase in the London Interbank Offered Rate (“LIBOR”). The decrease in capitalized interest was due to having lower cumulative development costs paid for our development projects in 2016 compared to 2015.

Loss on Early Extinguishment of Debt.For the year ended December 31, 2016, we incurred a loss of $1.2 million comprised of the write-off of fees related to the refinancing of our unsecured revolving credit facility (the "Unsecured Credit Facility”) and unsecured term loan (“Unsecured Term Loan”) in July 2016. No such loss was recorded in 2015.

Gain on Sale of Real Estate. Gain on sale of real estate was $22.8 million for the year ended December 31, 2016, compared to none for the year ended December 31, 2015. The gain was recognized on the sale of NJ1. We recognized an impairment loss of $122.5 million in the fourth quarter of 2015 for NJ1.

Net (Income) Loss Attributable to Redeemable Noncontrolling interests – Operating Partnership (DFT only). Net income attributable to redeemable noncontrolling interests – operating partnership for the year ended December 31, 2016 was $24.2 million as compared to a net loss of $6.0 million for the year ended December 31, 2015. The $30.2 million increase was primarily due to the noncontrolling interests portion of the impairment charge of $122.5 million in 2015 and the gain on sale of NJ1 in 2016 of $22.8 million, described above.

Net Income (Loss) Attributable to Common Shares. Net income attributable to common shares for the year ended December 31, 2016 was $124.0 million as compared to a net loss of $25.3 million for the year ended December 31, 2015. The $149.3 million increase was primarily due to the impairment charge of $122.5 million in 2015 and the gain on sale of NJ1 of

54

$22.8 million in 2016 noted above, increased revenue as discussed above and a $6.5 million decrease in preferred dividends in 2016, as we decreased the amount of preferred stock outstanding and decreased the dividend rate by issuing our new Series C preferred stock and redeeming our 7.875% Series A Cumulative Redeemable Perpetual Preferred Stock (the “Series A Preferred Stock”) and our 7.625% Series B Cumulative Redeemable Perpetual Preferred Stock (the Series B Preferred Stock”), partially offset by increased operating expenses as discussed above and the write-off of $12.5 million of issuance costs related to the redemption of the Series A Preferred Stock and the Series B Preferred Stock.

Year Ended December 31, 2015 Compared to Year Ended December 31, 2014

Operating Revenues. Operating revenues for the year ended December 31, 2015 were $452.4 million. This includes base rent of $298.6 million, which includes a property management fee on many of our leases, customer recoveries of $139.5 million and other revenues of $14.3 million, partially from à la carte projects performed for our customers by our TRS. This compares to revenues of $417.6 million for the year ended December 31, 2014. The increase of $34.8 million, or 8.3%, was primarily due to new leases commencing at ACC5, ACC7 Phases I and II, SC1 Phase IIB and CH2 Phase I and increased revenues from à la carte projects, partially offset by reduced revenue from a former customer who declared bankruptcy and the vacancy of ACC2 in the fourth quarter of 2015.

Operating Expenses. Operating expenses for the year ended December 31, 2015 were $412.8 million, compared to $254.7 million for the year ended December 31, 2014. The increase of $158.1 million, or 62.1%, included an impairment charge of $122.5 million resulting from our decision to market NJ1 for sale. Excluding the impairment charge, the increase in operating expenses was $35.6 million, or 14.0%, primarily due to the following: a $12.7 million increase in operating costs primarily resulting from a full year of operations at ACC7 Phase I which opened in September 2014, SC1 Phase IIB opening in May 2015, CH2 Phase I opening in July 2015 and ACC7 Phase II opening in December 2015; increased real estate taxes and insurance of $7.1 million related to the data center openings noted above and increases in real estate taxes at SC1 and VA4; a $7.3 million increase in depreciation and amortization from the data center openings noted above; a $7.6 million increase in other expenses due to the increased a la carte projects, noted above; $6.1 million in severance costs and charges related to the acceleration of equity awards primarily related to the departure of our former chief executive officer in February 2015; and a $0.9 million increase in general and administrative expense primarily due to increases in payroll and professional expenses.

Interest Expense. Interest expense, including amortization of deferred financing costs, for the year ended December 31, 2015 was $43.7 million compared to interest expense of $36.7 million for the year ended December 31, 2014. Total interest incurred for the year ended December 31, 2015 was $56.0 million, of which $12.3 million was capitalized, as compared to $46.9 million for 2014, of which $10.2 million was capitalized. The increase in total interest incurred period over period was primarily due to higher debt outstanding to finance our development projects and an increase in our average interest rate, which resulted from the issuance of $250 million of the Unsecured Notes due 2023 in June 2015. The increase in capitalized interest was due to having higher cumulative development costs paid for our development projects in 2015 compared to 2014.

Loss on Early Extinguishment of Debt.For the year ended December 31, 2014, we incurred a loss of $1.7 million comprised of the write-off of $0.3 million of loan fees related to the refinancing of the Unsecured Credit Facility in May 2014 and a loss of $1.4 million due to the refinancing of the Unsecured Term Loan in July 2014 that was treated as a partial extinguishment in accordance with GAAP.

Net Loss (Income) Attributable to Redeemable Noncontrolling interests – Operating Partnership (DFT only). Net loss attributable to redeemable noncontrolling interests – operating partnership for the year ended December 31, 2015 was $6.0 million as compared to $18.7 million of net income for the year ended December 31, 2014. The $24.7 million decrease was primarily due to the impairment charge of $122.5 million described above.

Net (Loss) Income Attributable to Common Shares. Net loss attributable to common shares for the year ended December 31, 2015 was $25.3 million as compared to $78.7 million of net income for the year ended December 31, 2014. The $104.0 million decrease was primarily due to the impairment charge of $122.5 million noted above, partially offset by increased operating income from the lease-up of our data centers.

Liquidity and Capital Resources

Discussion of Cash Flows

The discussion of cash flows below is for both DFT and the Operating Partnership. The only difference between the cash flows of DFT and the Operating Partnership for the years ended December 31, 2016 and 2015 was a $4.2 million bank account at DFT that is not part of the Operating Partnership.

55

Year Ended December 31, 2016 Compared to Year Ended December 31, 2015

Net cash provided by operating activities increased by $35.0 million, or 13.7%, to $290.0 million for the year ended December 31, 2016, as compared to $255.0 million in 2015. The increase is primarily due to higher cash rents received from customers and an increase in advance rents and other liabilities, partially offset by a decrease in prepaid expenses and other assets.

Net cash used in investing activities increased by $19.3 million, or 8.0%, to $261.0 million for the year ended December 31, 2016 compared to $241.7 million in 2015. The majority of cash used in investing activities in each period was expenditures for projects under development. Development costs paid during 2016 were $77.9 million higher than development costs paid during 2015 as more projects were under development in 2016 as compared to 2015. We also purchased land in Ashburn, Virginia and Hillsboro, Oregon and an existing shell building in Vaughan, Ontario totaling $73.3 million in 2016 compared to an $8.6 million purchase of land in Elk Grove Village, Illinois in 2015. There was a $1.4 million increase in improvements to real estate for the year ended December 31, 2016 as compared to 2015 as projects were completed at ACC2 in 2016 for the new customer. Capitalized interest declined $1.2 million as there were lower cumulative development costs paid for our projects in 2016 versus 2015. The increase is partially offset due to the $123.5 million in net proceeds received from the sale of NJ1.

Net cash used in financing activities was $21.6 million for the year ended December 31, 2016 compared to $11.7 million in 2015. Cash used in financing activities for the year ended December 31, 2016 primarily consisted of $351.3 million used to redeem the Series A Preferred Stock and Series B Preferred Stock, $189.0 million paid for dividends and distributions, the payment of $5.9 million of financing costs related to the amendment and restatement of the Unsecured Credit Facility and the Unsecured Term Loan which resulted in the Unsecured Credit Facility increasing from $700 million to $750 million and $3.8 million of principal repayments on the ACC3 Term Loan, partially offset by the issuance of common stock which generated net proceeds of $275.5 million, the issuance of our Series C Preferred Stock, which generated net proceeds of $194.3 million, $50.9 million of net borrowings made on the Unsecured Credit Facility and $7.6 million primarily from proceeds received from stock option exercises. Cash used in financing activities for the year ended December 31, 2015 primarily consisted of $163.3 million paid for dividends and distributions, $60.0 million of net repayments made on the Unsecured Credit Facility, $31.9 million for the repurchase of common shares and the payment of $4.7 million of financing costs related to the issuance of the Unsecured Notes due 2023 and an increase in the size of the Unsecured Credit Facility, partially offset by $248.0 million of proceeds from the Unsecured Notes due 2023. 

Year Ended December 31, 2015 Compared to Year Ended December 31, 2014

Net cash provided by operating activities increased by $10.5 million, or 4.3%, to $255.0 million for the year ended December 31, 2015, as compared to $244.5 million in 2014. The increase is primarily due to higher cash rents received from customers and decreases in prepaid expenses and other assets partially offset by less of an increase in prepaid rent and other liabilities and an increase in rents and other receivables.

Net cash used in investing activities decreased by $35.6 million, or 12.8%, to $241.7 million for the year ended December 31, 2015 compared to $277.3 million in 2014. The majority of cash used in investing activities in each period was expenditures for projects under development. Development costs paid during 2015 were $48.0 million lower than development costs paid during 2014, because projects under development in 2015 consisted of the second or third phases of a data center facility, which are less capital intensive than the first phase of the facility, where the entire shell of the facility is constructed. This decrease was partially offset by an $8.6 million purchase of land in Elk Grove Village, Illinois in 2015 compared to no land purchases in 2014, a $1.9 million increase in capitalized interest and a $1.5 million increase in improvements to real estate for the year ended December 31, 2015 as compared to 2014.

Net cash used in financing activities was $11.7 million for the year ended December 31, 2015 compared to net cash provided by financing activities of $23.6 million in 2014. Cash used in financing activities for the year ended December 31, 2015 primarily consisted of $163.3 million paid for dividends and distributions, $60.0 million of net repayments made on the Unsecured Credit Facility, $31.9 million for the repurchase of common shares and the payment of $4.7 million of financing costs related to the issuance of the Unsecured Notes due 2023 and an increase in the size of the Unsecured Credit Facility, partially offset by $248.0 million of proceeds from the Unsecured Notes due 2023. Cash provided by financing activities for the year ended December 31, 2014 consisted of $96.0 million of proceeds from the final draw of the Unsecured Term Loan, $60.0 million of borrowings from the Unsecured Credit Facility and $4.4 million primarily from proceeds received from stock option exercises. This was partially offset by $132.9 million paid for dividends and distributions and the payment of $3.8 million of financing costs related to the amendments of the Unsecured Credit Facility, the ACC3 Term Loan and the Unsecured Term Loan.

Capital Resources

The development of wholesale data centers is capital intensive. Such development not only requires us to make substantial capital investments, but also increases our operating expenses, which negatively impacts our cash flows from operations until leases are executed and we begin to collect cash rents from these leases. In addition, because DFT has elected to be taxed as a REIT for federal income tax purposes, we are required to distribute at least 90% of our taxable income, excluding any net capital gain, to our stockholders annually. Accordingly, we fund a portion of the cost of data center development from additional capital because cash provided by operating activities is not sufficient to fund our development costs after we make the required dividends and distributions to our stockholders and unitholders.

We expect to meet our liquidity needs from cash provided by operating activities, from funds available under the Unsecured Credit Facility and from additional capital from external sources. For 2017, we currently expect that our expenditures of capital for the construction of data center facilities will be approximately $600 - $650 million, which exceeds expected cash provided from operations after payment of dividends and distributions for 2017 and the amount available under the Unsecured Credit Facility as of December 31, 2016. During 2017, when market conditions permit, we plan to obtain additional capital and permanent capital financing for the funds drawn under the Unsecured Credit Facility, which we expect to obtain through unsecured and secured borrowings, construction financings and the issuance of additional preferred and/or common equity. In determining the source of capital to meet our long-term liquidity needs, we will evaluate our level of indebtedness and covenants, in particular with respect to the covenants under the unsecured notes and unsecured line of credit, our expected cash flow from operations, the state of the capital markets, interest rates and other terms for borrowing, and the relative timing considerations and costs of borrowing or issuing equity securities. We face many risks that could cause our actual expenditures of capital for the construction of data center facilities to differ materially from the amount forecasted above, including the risks set forth in “Our long-term growth depends upon the successful development of our data centers, and unexpected costs or changes in permit requirements or environmental regulations may delay or preclude the construction of additional data centers, thereby materially adversely affecting our business, results of operations and financial condition.” in Item 1A, Risk Factors, above.

In March 2016, we completed a secondary underwritten public offering of 7,613,000 shares of common stock, at a public offering price of $37.75 per share. Net proceeds from the offering were $275.5 million, after deducting the underwriting discount and other offering expenses.

In May 2016, we completed an underwritten public offering of 8,050,000 shares of Series C cumulative redeemable perpetual preferred stock at a public offering price of $25.00 per share. Net proceeds from the offering were $194.3 million, after deducting the underwriting discount and other offering expenses.

57

From May 2016 to July 2016, we redeemed all shares outstanding of the Series A Preferred Stock and Series B Preferred Stock totaling $351.3 million.

In June 2016, we sold our NJ1 data center facility for a purchase price of $125.0 million. Net proceeds from the sale were approximately $123.5 million after deducting selling costs.

In July 2016, we amended and restated the Unsecured Credit Facility and the Unsecured Term Loam. The total commitments under the Unsecured Credit Facility increased from $700 million to $750 million. In November 2016, we added a Canadian dollar sublimit of up to $185 million (approximately CAD $250 million) to the Unsecured Credit Facility. This will allow us to borrow in Canadian dollars to fund our TOR1 data center development in Vaughan, Ontario. As of December 31, 2016, we had CAD $55 million outstanding and USD $10 million outstanding on the Unsecured Credit Facility for a total of USD $50.9 million outstanding.

DFT's ability to pay dividends to its stockholders is dependent on the receipt of distributions from the Operating Partnership, which in turn is dependent on the data center properties generating operating income. The indentures that govern the Unsecured Notes due 2021 and the Unsecured Notes due 2023 limit DFT’s ability to pay dividends, but allow DFT to pay the minimum dividends necessary to meet its REIT income distribution requirements.

A summary of our total debt as of December 31, 2016 and December 31, 2015 is as follows:

Outstanding Indebtedness

Unsecured Credit Facility and Unsecured Term Loan

On July 25, 2016, we entered into an amended and restated credit agreement with a syndicate of banks (the "Amended and Restated Credit Agreement") that includes the following:

• an unsecured revolving credit facility with a total commitment of $750 million (the "Unsecured Credit Facility"); and

• an unsecured term loan facility, which has a total commitment and amount outstanding of $250 million (the "Unsecured Term Loan").

In November 2016, we added a Canadian dollar sublimit of up to $185 million (approximately CAD $250 million) to the Unsecured Credit Facility, which allows us to borrow in Canadian dollars to fund our TOR1 data center development in Vaughan, Ontario. In addition, the Canadian borrowings allow us to hedge our foreign currency investment risk by having these liabilities translate at the same exchange rates as our Canadian assets at the end of each period. In 2016, we designated all of the Canadian borrowings on our Unsecured Credit Facility, which totaled CAD $62.0 million as of December 31, 2016, as a net investment hedge of our Canadian assets. For the effective portion of these net investment hedges, the currency translation effects of these borrowings are reflected in accumulated other comprehensive loss within shareholders' equity on our consolidated balance sheets, where they offset the currency translation effects of our investment in our Canadian assets. There was no ineffectiveness for our net investment hedges during 2016.

At our option, we may increase the total commitment under the Unsecured Credit Facility and the Unsecured Term Loan to $1.25 billion, if one or more lenders commit to being a lender for the additional amount and certain other customary conditions are met.

Prior to July 25, 2016, the Unsecured Credit Facility and the Unsecured Term Loan were outstanding under separate credit agreements.

The obligations under the Amended and Restated Credit Agreement are unconditionally guaranteed, jointly and severally, on a senior unsecured basis by DFT and all of the Operating Partnership’s subsidiaries that currently guaranty the obligations under the Unsecured Notes due 2021, listed below. Prior to July 25, 2016, the separate credit agreements that governed the Unsecured Credit Facility and the Unsecured Term Loan provided for substantially the same guarantees as the Amended and Restated Credit Agreement. We may prepay the Unsecured Credit Facility and the Unsecured Term Loan at any time, in whole or in part, without penalty or premium.

The Amended and Restated Credit Agreement requires that DFT, the Operating Partnership and their subsidiaries comply with various covenants, including with respect to restrictions on liens, incurring indebtedness, making investments, effecting mergers and/or asset sales, and certain limits on dividend payments, distributions and purchases of DFT's stock. In addition, the facility imposes financial maintenance covenants relating to, among other things, the following matters:

• unsecured debt not exceeding 60% of the value of unencumbered assets, subject to an increase up to 65% following a material acquisition;

• net operating income generated from unencumbered properties divided by the amount of unsecured debt (net of unrestricted cash and cash equivalents) being not less than 12.5%, subject to a decrease to not less than 10.0% following a material acquisition;

• total indebtedness not exceeding 60% of gross asset value, subject to an increase up to 65% following a material acquisition;

• fixed charge coverage ratio being not less than 1.70 to 1.00; and

• tangible net worth being not less than $2.3 billion plus 75% of the sum of (i) net equity offering proceeds after July 25, 2016 (but excluding such net offering proceeds that are used within ninety (90) days following the consummation of the applicable equity offering for permitted equity redemptions) and (ii) the value of equity interests issued in connection with a contribution of assets to the borrower or its subsidiaries; and

• until an investment grade unsecured debt credit rating has been achieved, unhedged variable rate debt not exceeding 30% of gross asset value.

59

The Amended and Restated Credit Agreement includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations of the Operating Partnership under the facility to be immediately due and payable.

We were in compliance with all covenants under the Unsecured Credit Facility and the Unsecured Term Loan as of December 31, 2016.

The Unsecured Credit Facility matures on July 25, 2020.

We may elect to have borrowings under the Unsecured Credit Facility bear interest at either the London Interbank Offered Rate (“LIBOR”) or a base rate, which is based on the lender's prime rate, in each case plus an applicable margin. Prior to our receiving an investment grade credit rating, the applicable margin added to LIBOR and the base rate is based on the table below.

Pricing Level	Ratio of Total Indebtedness to Gross Asset Value	LIBOR Rate Loans		Base Rate Loans
Level 1	Less than or equal to 35%	1.55	%	0.55	%
Level 2	Greater than 35% but less than or equal to 40%	1.65	%	0.65	%
Level 3	Greater than 40% but less than or equal to 45%	1.80	%	0.80	%
Level 4	Greater than 45% but less than or equal to 52.5%	1.95	%	0.95	%
Level 5	Greater than 52.5%	2.15	%	1.15	%

The applicable margin is currently set at pricing Level 1. The terms of the Unsecured Credit Facility provide for the adjustment of the applicable margin from time to time according to the ratio of the Operating Partnership’s total indebtedness to gross asset value in effect from time to time.

In the event we receive an investment grade credit rating, borrowings under the Unsecured Credit Facility will bear interest based on the table below.

		Applicable Margin
Credit Rating Level	Credit Rating	LIBOR Rate Loans		Base Rate Loans
Level 1	Greater than or equal to A- by S&P or A3 by Moody’s	0.85	%	0.00	%
Level 2	Greater than or equal to BBB+ by S&P or Baa1 by Moody’s	0.90	%	0.00	%

Level 5	Less than BBB- by S&P or Baa3 by Moody’s	1.55	%	0.55	%

Following the receipt of such investment grade rating, the terms of the Unsecured Credit Facility provide for the adjustment of the applicable margin from time to time according to the rating then in effect.

The amount available for borrowings under the Unsecured Credit Facility is determined according to a calculation comparing the value of certain unencumbered properties designated by the Operating Partnership at such time relative to the amount of the Operating Partnership's unsecured debt. Up to $35 million of the borrowings under the Unsecured Credit Facility may be used for letters of credit.

As of December 31, 2016, we had no letters of credit outstanding. As of December 31, 2016, we had USD $10.0 million and CAD $55.0 million outstanding on the Unsecured Credit Facility for a total of USD $50.9 million outstanding. As of February 23, 2017, we had USD $60.0 million and CAD $62.0 million outstanding on the Unsecured Credit Facility for a total of approximately USD $107.1 million outstanding.

The Unsecured Term Loan matures on January 21, 2022.

Under the terms of the Unsecured Term Loan, we may elect to have borrowings under the loan bear interest at either LIBOR or a base rate, which is based on the lender's prime rate, in each case plus an applicable margin. Prior to our receiving an investment grade credit rating, the applicable margin added to LIBOR and the base rate is based on the table below.

ACC3 Term Loan

We have a $111.3 million term loan facility that is secured by our ACC3 data center facility and an assignment of the lease agreement between us and the customer of ACC3 (the "ACC3 Term Loan"). The borrower, one of our subsidiaries, may elect to have borrowings under the ACC3 Term Loan bear interest at (i) LIBOR plus 1.55% or (ii) a base rate, which is based on the lender's prime rate, plus 0.55%. The interest rate is currently at LIBOR plus 1.55%. The ACC3 Term Loan matures on March 27, 2018, and we may prepay the ACC3 Term Loan at any time, in whole or in part, without penalty or premium. The Operating Partnership has guaranteed the outstanding principal amount of the ACC3 Term Loan, plus interest and certain costs under the loan.

The ACC3 Term Loan imposes financial maintenance covenants relating to, among other things, the following matters:

• consolidated total indebtedness of the Operating Partnership not exceeding 60% of gross asset value of the Operating Partnership;

• fixed charge coverage ratio of the Operating Partnership being not less than 1.70 to 1.00;

• tangible net worth of the Operating Partnership being not less than $1.3 billion plus 80% of the sum of (i) net equity offering proceeds and (ii) the value of equity interests issued in connection with a contribution of assets to the Operating Partnership or its subsidiaries; and

• debt service coverage ratio of the borrower not less than 1.50 to 1.00.

We were in compliance with all of the covenants under the ACC3 Term Loan as of December 31, 2016.

Unsecured Notes due 2021

On September 24, 2013, the Operating Partnership completed the sale of $600 million of 5.875% senior unsecured notes due 2021, which we refer to as the Unsecured Notes due 2021. The Unsecured Notes due 2021 were issued at face value and mature on September 15, 2021. We pay interest on the Unsecured Notes due 2021 semi-annually, in arrears, on March 15th and September 15th of each year.

The Unsecured Notes due 2021 are unconditionally guaranteed, jointly and severally, on a senior unsecured basis by DFT and certain of the Operating Partnership’s subsidiaries, including the subsidiaries that own the ACC2, ACC4, ACC5, ACC6, VA3, VA4, CH1 and SC1 data centers (collectively, the “Subsidiary Guarantors”), but excluding the subsidiaries that own the ACC3, ACC7, ACC9, ACC10, CH2, CH3 and TOR1 data centers, the ACC8, ACC11, OR1 and OR2 parcels of land, our taxable REIT subsidiary, DF Technical Services LLC and our property management subsidiary, DF Property Management LLC.

61

The Unsecured Notes due 2021 rank (i) equally in right of payment with all of the Operating Partnership's existing and future senior unsecured indebtedness, (ii) senior in right of payment with all of its existing and future subordinated indebtedness, (iii) effectively subordinate to any of the Operating Partnership's existing and future secured indebtedness and (iv) effectively junior to any liabilities of any subsidiaries of the Operating Partnership that do not guarantee the Unsecured Notes due 2021. The guarantees of the Unsecured Notes due 2021 by DFT and the Subsidiary Guarantors rank (i) equally in right of payment with such guarantor's existing and future senior unsecured indebtedness, (ii) senior in right of payment with all of such guarantor's existing and future subordinated indebtedness and (iii) effectively subordinate to any of such guarantor's existing and future secured indebtedness

The Unsecured Notes due 2021 may be redeemed at the Operating Partnership's option, in whole or in part, at any time, at the following redemption prices (expressed as percentages of the principal amount thereof) if redeemed during the 12-month period commencing September 15 of the years indicated below, in each case together with accrued and unpaid interest to the date of redemption:

Year	Redemption Price
2016	104.406	%
2017	102.938	%
2018	101.469	%
2019 and thereafter	100.000	%

If there is a change of control (as defined in the indenture governing the Unsecured Notes due 2021) of the Operating Partnership or DFT, we must offer to purchase the Unsecured Notes due 2021 at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest. In addition, in certain circumstances we may be required to use the net proceeds of asset sales to purchase a portion of the Unsecured Notes due 2021 at 100% of the principal amount thereof, plus accrued and unpaid interest.

The Unsecured Notes due 2021 have certain covenants limiting the ability of or prohibiting the Operating Partnership and certain of its subsidiaries from, among other things, (i) incurring secured or unsecured indebtedness, (ii) entering into sale and leaseback transactions, (iii) making certain dividend payments, distributions, purchases of DFT's common stock and investments, (iv) entering into transactions with affiliates, (v) entering into agreements limiting the ability to make certain transfers and other payments from subsidiaries, (vi) engaging in sales of assets or (vii) engaging in certain mergers, consolidations or transfers/sales of all or substantially all assets. However, DFT may pay the minimum dividend necessary to meet its REIT income distribution requirements.

The Unsecured Notes due 2021 also require the Operating Partnership and the Subsidiary Guarantors to maintain total unencumbered assets of at least 150% of their unsecured debt on a consolidated basis. The Unsecured Notes due 2021 also have customary events of default, including, but not limited to, nonpayment, breach of covenants, and payment or acceleration defaults in certain other indebtedness of ours or certain of our subsidiaries. Upon an event of default, the holders of the Unsecured Notes due 2021 or the trustee may declare the Unsecured Notes due 2021 due and immediately payable. We were in compliance with all covenants under the Unsecured Notes due 2021 as of December 31, 2016.

Unsecured Notes due 2023

On June 9, 2015, the Operating Partnership completed the sale of $250 million of 5.625% senior unsecured notes due 2023, which we refer to as the Unsecured Notes due 2023. The Unsecured Notes due 2023 were issued at 99.205% of par and mature on June 15, 2023. We pay interest on the Unsecured Notes due 2023 semi-annually, in arrears, on June 15th and December 15th of each year.

The Unsecured Notes due 2023 are unconditionally guaranteed, jointly and severally, on a senior unsecured basis by DFT and the same Subsidiary Guarantors as those that guarantee the Unsecured Notes due 2021.

The ranking of the Unsecured Notes due 2023 and the guarantees of these notes are the same as the ranking of the Unsecured Notes due 2021 and the guarantees of those notes.

At any time prior to June 15, 2018, the Operating Partnership may redeem the Unsecured Notes due 2023, in whole or in part, at a price equal to the sum of (i) 100% of the principal amount of the Unsecured Notes due 2023 to be redeemed, plus (ii) a make-whole premium and accrued and unpaid interest. The Unsecured Notes due 2023 may be redeemed at the Operating Partnership's option, in whole or in part, at any time, on and after June 15, 2018 at the following redemption prices (expressed as percentages of the principal amount thereof) if redeemed during the 12-month period commencing June 15 of the years indicated below, in each case together with accrued and unpaid interest to the date of redemption:

Off-Balance Sheet Arrangements

As of December 31, 2016, we did not have any off-balance sheet arrangements.

Critical Accounting Policies

We have provided a summary of our significant accounting policies in Note 2 to our financial statements included elsewhere in this Form 10-K. 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 during the reporting period. Our actual results may differ from these estimates. We describe below the accounting policies that we deem critical and require material subjective or complex judgments and that have the most significant impact on our financial condition and results of operations. We evaluate these estimates on an ongoing basis, based upon information currently available and on various assumptions we believe are reasonable as of the date hereof.

Revenue Recognition. Rental income is recognized using the straight-line method over the terms of the customers' leases, which commences when control of the space and the critical power have been provided to the customer. Deferred rent included in our consolidated balance sheets represents the aggregate excess of rental revenue recognized on a straight-line basis over the contractual rental payments that will be recognized under the remaining terms of the leases. The majority of our leases contain provisions under which the customers reimburse us for their portion of property operating expenses that we incur. Such reimbursements are recognized in the period that the expenses are incurred. We recognize amortization of the value of acquired above market customer leases as a reduction of rental revenue and of below market leases as an increase to rental revenue.

We must make subjective estimates as to when our revenue is earned, including a determination of the lease commencement date for accounting purposes, the existence of lease inducements and early termination clauses with penalty payments and the collectability of our accounts receivable related to rent, deferred rent, expense reimbursements and other income. We analyze individual accounts receivable and historical bad debts, customer concentrations, customer creditworthiness and current economic trends when evaluating the adequacy of our allowance for bad debts. These estimates have a direct impact on net income because a higher bad debt allowance would result in lower net income, and recognizing rental revenue as earned in one period versus another would result in higher or lower net income for a particular period.

Capitalization of costs. We capitalize direct and indirect costs related to construction and development, including property taxes, insurance and financing costs relating to properties under development. In addition, we cease cost capitalization after a development is placed in service or if development of a project is suspended. We capitalize pre-acquisition costs related to probable property acquisitions and write-off these costs if the acquisition of the property or development of the project is no longer deemed probable. The selection of costs to capitalize and the determination of whether a proposed acquisition is probable are subjective and depends on many assumptions including the timing of potential acquisitions and the probability that future acquisitions occur. All capital improvements for the income producing properties that extend the property's useful life are capitalized. We also capitalize the costs to obtain a lease if the execution of the lease is deemed probable and write-off these costs if the execution of the lease is no longer deemed probable. Variations in these assumptions would yield different amounts of capitalized costs in the periods presented. For the years ended December 31, 2016, 2015 and 2014, we capitalized $8.0 million, $7.5 million and $4.5 million, respectively, of internal development and leasing costs on all of our data centers.

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

64

investments in real estate. These assessments have a direct impact on our net income. The following presents the major components of our properties and the useful lives over which they are depreciated.

Component	Average % of Total		Component Life (years)
Land	3	%	N/A
Building improvements	30	%	40
Electrical infrastructure—power distribution units	3	%	20
Electrical infrastructure—uninterrupted power supply	20	%	25
Electrical infrastructure—switchgear/transformers	18	%	30
Fire protection	2	%	40
Security systems	1	%	20
Mechanical infrastructure—heating, ventilating and air conditioning	6	%	20
Mechanical infrastructure—chiller pumps/building automation	7	%	25
Mechanical infrastructure—chilled water storage and pipes	10	%	30
Total/weighted average life	100	%	30

We regularly perform preventive maintenance on our data center components to ensure continual operation and avoid downtime at our data centers. These maintenance costs are expensed as incurred and included as property operating costs on our consolidated statement of operations.

Asset impairment evaluation. We review the carrying value of our net real estate on a quarterly basis. We base our review on an estimate of the undiscounted future cash flows (excluding interest charges) expected to result from the real estate investment's use and eventual disposition. We estimate the fair value of rental properties utilizing a discounted cash flow analysis that includes projections of future revenues, expenses and capital improvement costs, similar to the income approach that is commonly utilized by appraisers. 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 evaluation indicates that we may be unable to recover the carrying value of a real estate investment, an impairment loss would be recorded to the extent that the carrying value exceeds the estimated fair value of the property, which would result 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 from properties considered to be long-lived assets to be held and used are considered on an undiscounted basis to determine whether an asset has been impaired, our strategy of holding properties over the long-term directly decreases the likelihood of recording an impairment loss. If this strategy changes or market conditions dictate an earlier sale date or if we determine that development of a project is no longer viable, an impairment loss may be recognized and such loss could be material. If we determine that impairment has occurred, the affected assets must be reduced to their fair value. In 2015, we recorded an impairment charge of $122.5 million resulting from our decision to market NJ1 for sale. This property was sold in the second quarter of 2016.

Recently Issued Accounting Pronouncements

Revenue Recognition - In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update No. 2014-09, Revenue from Contracts with Customers (Topic 606). The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. We are required to apply the new standard in the first quarter of 2018 and expect to elect the modified retrospective method of application of the standard. Although the standard does not apply to leases, we have assessed the impact on our financial position and results of operations. The standard will change our method of recognizing revenue on service and installation contracts included in other revenue in the accompanying consolidated statements of operations from the completed contract method to a method that recognizes revenue over the course of the contract based on the goods or services transferred to date relative to the remaining goods or services promised under the contract. We do not expect that this change will have a material effect on our financial position or results of operations. In addition, we currently do not believe the standard will have a material impact on how we recognize revenues from tenants with respect to operating expense recoveries on our financial position or results of operations.

65

Leases - In February 2016, the FASB issued Accounting Standards Update No. 2016-02 - Leases (Topic 842). We are required to apply the new standard in the first quarter of 2019. The Company’s leases consist of both lease components that will be accounted for under this standard and non-lease components such as operating expense recovery income that will be accounted for under ASU 2014-09, Revenue from Contracts with Customers. The standard does not fundamentally change the lessor accounting model, and we do not believe that the new standard will have a material impact on our financial position or results of operations.

Financial Instruments - In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. Under this guidance, a company will be required to use a new forward-looking "expected loss" model for trade and other receivables that generally will result in the earlier recognition of allowances for losses. We are required to apply the new standard in the first quarter of 2020 and do not believe that the new standard will have a material effect on our financial position or results of operations.

Statement of Cash Flows - In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. The standard provides guidance on eight specific cash flow classification issues including debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, and separately identifiable cash flows and application of the predominance principle. We are required to apply the new standard in the first quarter of 2018 and do not believe that the new standard will have a material effect on our financial position or results of operations.

Statement of Cash Flows - Restricted Cash - In November 2016, the FASB issued Accounting Standards Update No. 2016-18 (Topic 230), Restricted Cash. The standard requires restricted cash to be included with cash and cash equivalents when reconciling the beginning and ending amounts in the statement of cash flows. We are required to apply the new standard in the first quarter of 2018 and do not believe that the new standard will have a material effect on our financial position or results of operations.

Business Combinations - In January 2017, the FASB issued Accounting Standards Update No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The standard narrows the existing definition of a business and provides a framework for evaluating whether a transaction should be accounted for as an acquisition of assets or a business. The guidance is effective for public entities for fiscal years beginning after December 15, 2017 and interim periods within those years. However, we will early-adopt the standard effective January 1, 2017. As a result of this new guidance, acquisitions may now result in an asset purchase rather than a business combination. We do not believe that the new standard will have a material effect on our financial position or results of operations.

Recently Adopted Accounting Pronouncements

Going Concern - In August 2014, the FASB issued Accounting Standards Update No. 2014-15 - Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. Under this guidance, management is required to perform a going concern evaluation similar to the auditor's evaluation required by standards issued by the Public Company Accounting Oversight Board and the American Institute of Certified Public Accountants. This evaluation is required for both annual and interim reporting periods. We adopted the new standard in the fourth quarter of 2016, and there was no material effect on our financial position or results of operations.

Consolidation - In February 2015, the FASB issued Accounting Standards Update No. 2015-02 - Consolidation: Amendments to the Consolidation Analysis, which amends the criteria for determining variable interest entities (“VIEs”), amends the criteria for determining if a service provider possesses a variable interest in a VIE, and eliminates the presumption that a general partner should consolidate a limited partnership. We adopted this standard as of January 1, 2016, and there was no material effect on our financial position or results of operations.

Stock Compensation - In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The new guidance affects two areas of our accounting. First, the guidance increases the amount an employer can withhold to cover income taxes on awards and still qualify for the exception to liability classification for shares used to satisfy the employer's statutory income tax withholding obligation. An employer is now allowed to withhold shares up to the amount of tax potentially owed using the maximum statutory tax rate in each jurisdiction. Second, companies now have the ability to make a policy election to account for forfeitures as they occur versus recording a forfeiture estimate. We early-adopted this standard as of January 1, 2016 and elected to account for forfeitures as they occur versus recording a forfeiture estimate. Per the guidance, we used a modified retrospective transition method of adoption, with a cumulative effect adjustment to accumulated deficit on our consolidated balance sheet as December 31, 2015 totaling less than $0.1 million.

(1) Funds from operations, or FFO, is used by industry analysts and investors as a supplemental operating performance measure for REITs. We calculate FFO in accordance with the definition that was adopted by the Board of Governors of the National Association of Real Estate Investment Trusts, or NAREIT. FFO, as defined by NAREIT, represents net income determined in accordance with GAAP, excluding extraordinary items as defined under GAAP, impairment charges on depreciable real estate assets and gains or losses from sales of previously depreciated operating real estate assets, plus specified non-cash items, such as real estate asset depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. We also present FFO attributable to common shares and OP units, which is FFO excluding preferred stock dividends. FFO attributable to common shares and OP units per share is calculated on a basis consistent with net income attributable to common shares and OP units and reflects adjustments to net income for preferred stock dividends.

We use 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 period over period, captures trends in occupancy rates, rental rates and operating expenses. We also believe that, as a widely recognized measure of the performance of equity REITs, FFO may be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes real estate-related 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 effects and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited.

67

While FFO is a relevant and widely used measure of operating performance of equity REITs, other equity REITs may use different methodologies for calculating FFO and, accordingly, FFO as disclosed by such other REITs may not be comparable to our FFO. Therefore, we believe that in order to facilitate a clear understanding of our historical operating results, FFO should be examined in conjunction with net income as presented in the consolidated statements of operations. FFO should not be considered as an alternative to net income or to cash flow from operating activities (each as computed in accordance with GAAP) or as an indicator of our liquidity, nor is it indicative of funds available to meet our cash needs, including our ability to pay dividends or make distributions.

We present FFO with adjustments to arrive at Normalized FFO. Normalized FFO is FFO attributable to common shares and units excluding severance expense and equity accelerations, gain or loss on early extinguishment of debt, gain or loss on derivative instruments and write-offs of original issuance costs for redeemed preferred shares. We also present FFO with supplemental adjustments to arrive at Adjusted FFO (“AFFO”). AFFO is Normalized FFO excluding straight-line revenue, compensation paid with Company common shares, below market lease amortization and write-offs net of above market lease amortization and write-offs, non real estate depreciation and amortization, amortization of deferred financing costs, improvements to real estate and capitalized leasing commissions. AFFO does not represent cash generated from operating activities in accordance with GAAP and therefore should not be considered an alternative to net income as an indicator of our operating performance or as an alternative to cash flow provided by operations as a measure of liquidity and is not necessarily indicative of funds available to fund our cash needs including our ability to pay dividends. In addition, AFFO may not be comparable to similarly titled measurements employed by other companies. We use AFFO in management reports to provide a measure of REIT operating performance that can be compared to other companies using AFFO.

(2) Net income for the year ended December 31, 2016 includes a gain on sale of real estate of $22.8 million, write-off of issuance costs of preferred stock of $12.5 million, loss on early extinguishment of debt of $1.2 million and severance expense and equity accelerations of $0.9 million. Net income for the year ended December 31, 2015 includes an impairment on investment in real estate of $122.5 million and severance expense and equity accelerations of $6.1 million. Net income for the year ended December 31, 2014 includes loss on early extinguishment of debt of $1.7 million.

Related Party Transactions

Leasing Arrangements

Until September 2016, we leased approximately 9,337 square feet of office space in Washington, D.C., in an office building owned by an entity affiliated with our Chairman of the Board. In addition, our Executive Vice President, Chief Development Officer, is a non-managing member of this entity, and her sole interest is an approximately 1% non-managing membership interest. We believe that the terms of this lease were fair and reasonable and reflected the terms we could expect to obtain in an arm's length transaction for comparable space elsewhere in Washington, D.C. Rent expense under this lease was $0.3 million for the year ended December 31, 2016. The term of this lease expired on September 30, 2016, and we have entered into a new office lease with an unrelated party.

Acquisition of Undeveloped Land

In February 2016, we acquired two parcels of undeveloped land in Ashburn, Virginia, from entities controlled by our Chairman of the Board. One parcel is a 35.4 acre site that we purchased for $15.6 million, which we are using for the development of our ACC9 and ACC10 data center facilities. The managers of the entity that sold us this site are a limited liability company owned solely by our Chairman of the Board, which also owns approximately 7% of the seller, and a limited liability company owned solely by our former CEO which also owns approximately 1% of the seller. In connection with the purchase of this parcel, the parties agreed that the party who began improvement work first on any portion of the property that is adjacent to the road would be responsible for certain improvements to the road required by the county and that the cost of these improvements would be shared between the parties. We were the first to begin improvements to the land adjacent to the road, and we have begun to make the necessary improvements to the road as required. As of December 31, 2016, $0.3 million was due to us from the seller for its share of these improvement costs.

The other parcel is an 8.6 acre site that we purchased for $4.6 million. This parcel is being held for the future development of either a powered base shell or build-to-suit data center to be known as ACC11. Our Chairman of the Board and our former CEO are the managers of the limited liability company that manages the entity that sold us this site. Our Chairman of the Board directly and indirectly owns approximately 23% of the seller, and our former CEO directly and indirectly owns approximately 18% of the seller. In addition, Frederic V. Malek, one of our independent directors, is a non-managing member of the entity that owned this site. Mr. Malek’s sole interest in this entity is the ownership of an approximately 4% non-managing membership interest; he is neither an employee nor an executive officer of this entity. The purchase price for each site was based on an appraisal prepared for the Audit Committee of our Board of Directors by an independent appraisal firm.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our future income, cash flows and fair values relevant to our financial instruments are dependent upon prevalent market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates.

Our variable rate debt consists of the ACC3 Term Loan, the Unsecured Term Loan and the Unsecured Credit Facility. The ACC3 Term Loan, the Unsecured Term Loan and the US dollar-denominated borrowings under the Unsecured Credit facility currently bear interest at a rate equal to LIBOR plus an applicable margin. The Canadian dollar-denominated borrowings under the Unsecured Credit Facility bear interest at a rate equal to the Canadian Dollar Offered Rate ("CDOR") plus an applicable margin. If the LIBOR and CDOR interest rates were to increase by 1%, the increase in interest expense on our variable rate debt outstanding as of December 31, 2016 would decrease future net income and cash flows by $4.1 million annually less the impact of capitalization of interest incurred on net income. Because one-month LIBOR was 0.77% and one-month CDOR was 0.94% as of December 31, 2016, a decrease in each of these rates to zero would increase future net income and cash flows by $3.2 million annually less the impact of capitalization of interest incurred on net income. 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 specific 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. We believe that we have effectively managed interest rate exposure because the majority of our indebtedness bears a fixed rate of interest. As of December 31, 2016, 67% of our indebtedness was fixed rate debt. We also utilize preferred stock to raise capital, the dividends required under the terms of which have a coupon rate that is fixed.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of DuPont Fabros Technology, Inc.

We have audited DuPont Fabros Technology, Inc.'s (the “Company”) internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). DuPont Fabros Technology Inc.'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 in Item 9A. Our responsibility is to express an opinion on the company's internal control over financial reporting based on our audit.

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

A company's internal control over financial reporting is a process designed 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, DuPont Fabros Technology, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of DuPont Fabros Technology, Inc. as of December 31, 2016 and 2015, and the related consolidated statements of operations, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2016, and our report dated February 23, 2017 expressed an unqualified opinion thereon.

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 DFT and the Operating Partnership, collectively. As of December 31, 2016, we held a fee simple interest in the following properties:

• 11 operating data centers – ACC2, ACC3, ACC4, ACC5, ACC6, ACC7, CH1, CH2, SC1 Phases I-II, VA3, and VA4;

• Five data center projects under development – ACC9 Phases I and II, CH3 Phase I, SC1 Phase III and TOR1 Phase IA;

• One shell of a data center currently under development – ACC10;

• Three data center projects available for future development – CH3 Phase II, TOR1 Phase IB and TOR1 Phase II;

• Land that may be used to develop four additional data centers – ACC8, ACC11, OR1 and OR2.

2. Significant Accounting Policies

Basis of Presentation

This report combines the annual reports on Form 10-K for the year ended December 31, 2016 of DuPont Fabros Technology, Inc. and DuPont Fabros Technology, L.P. References to “DFT” mean DuPont Fabros Technology, Inc. and its controlled subsidiaries; and references to the “Operating Partnership” or “OP” mean DuPont Fabros Technology, L.P. and its controlled subsidiaries.

We believe combining the annual reports on Form 10-K of DFT and the Operating Partnership into this single report provides the following benefits:

• enhances investors’ understanding of DFT 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;

• eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure in this report applies to both DFT and the Operating Partnership; and

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

We operate DFT and the Operating Partnership as one business. The management of DFT consists of the same employees as the management of the Operating Partnership.

We believe it is important for investors to understand the few differences between DFT and the Operating Partnership in the context of how DFT and the Operating Partnership operate as a consolidated company. DFT is a REIT, whose only material asset is its ownership of OP units of the Operating Partnership. As a result, DFT 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 unsecured debt of the Operating Partnership. DFT has not issued any indebtedness, but has guaranteed all of the unsecured debt of the Operating Partnership. The Operating Partnership, through its wholly-owned subsidiaries, holds all the real estate assets of the Company. Except for net proceeds from public equity issuances by DFT, which are contributed to the Operating Partnership in exchange for OP units or preferred units, the Operating Partnership generates all remaining capital required by our business. These sources include the Operating Partnership’s operations, its direct or indirect incurrence of indebtedness, and the issuance of partnership units.

As sole general partner with control of the Operating Partnership, DFT consolidates the Operating Partnership for financial reporting purposes. The presentation of stockholders’ equity and partners’ capital are the main areas of difference between the consolidated financial statements of DFT and those of the Operating Partnership. The Operating Partnership’s capital includes preferred units and general and limited common units that are owned by DFT and the other partners. DFT’s stockholders’ equity includes preferred stock, common stock, additional paid in capital, retained earnings and accumulated other comprehensive income (loss). The common limited partnership interests held by the limited partners (other than DFT) in the Operating Partnership are presented as “redeemable partnership units” in the Operating Partnership’s consolidated financial

87

statements and as “redeemable noncontrolling interests-operating partnership” in DFT’s consolidated financial statements. The only difference between the assets and liabilities of DFT and the Operating Partnership as of December 31, 2016 was a $4.2 million bank account held by DFT that is not part of the Operating Partnership. Net income is the same for DFT and the Operating Partnership.

The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements.

We have one reportable segment consisting of investments in data centers located in the United States and Canada. All of our properties generate similar types of revenues and expenses related to customer rent and reimbursements and operating expenses. The delivery of our products is consistent across all properties and although services are provided to a range of customers, the types of services provided to them are limited to a few core principles. 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.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Property

All capital improvements for the income-producing properties are capitalized to individual building components, including interest and real estate taxes incurred during the period of development, and depreciated over their estimated useful lives. Interest is capitalized during the period of development based upon applying the property’s specific borrowing rate to the actual development costs expended up to specific borrowings, if any, and then applying our weighted-average borrowing rate to any residual development costs expended during the construction period. Interest is capitalized until the property has reached substantial completion and is ready for its intended use. Interest costs capitalized totaled $11.0 million, $12.3 million and $10.2 million for the years ended December 31, 2016, 2015 and 2014, respectively. We cease interest capitalization when a development is placed in service or temporarily suspended.

We capitalize pre-development costs, including internal costs, incurred in pursuit of new development opportunities for which we believe future development is probable. Future development is dependent upon various factors, including zoning and regulatory approval, rental market conditions, construction costs and availability of capital. Pre-development costs incurred for which future development is not yet considered probable are expensed as incurred. In addition, if the status of such a pre-development opportunity changes, making future development no longer probable, any capitalized pre-development costs are written-off with a charge to expense. Furthermore, the revenue from incidental operations received from the current improvements in excess of any incremental costs are recorded as a reduction of total capitalized costs of the development project and not as a part of net income. The capitalization of costs during the development of assets (including interest and related loan fees, property taxes and other direct and indirect costs) begins when development efforts commence and ends when the asset, or a portion of the asset, is substantially complete and ready for its intended use. For the years ended December 31, 2016, 2015 and 2014, we capitalized $8.0 million, $7.5 million and $4.5 million, respectively, of internal development and leasing costs on all of our data centers.

The fair value of in-place leases consists of the following components, as applicable: (1) the estimated cost to replace the leases, including foregone rents during the period of finding a new customer, foregone recovery of customer pass-through, customer improvements, and other direct costs associated with obtaining a new customer (referred to as tenant origination costs); (2) the estimated leasing commissions associated with obtaining a new customer (referred to as leasing commissions); and (3) the above/below market cash flow of the leases, determined by comparing the projected cash flows of the leases in place to projected cash flows of comparable market-rate leases (referred to as lease intangibles). Tenant origination costs are included in buildings and improvements in our accompanying consolidated balance sheets and are amortized as depreciation expense on a straight-line basis over the average remaining life of the underlying leases. Leasing commissions are classified as deferred costs and are amortized as amortization expense on a straight-line basis over the remaining life of the underlying leases. Lease intangible assets and liabilities are classified as lease contracts above and below market value, respectively, and amortized on a straight-line basis as decreases and increases, respectively, to rental revenue over the remaining life of the underlying leases. Should a customer terminate its lease early, the unamortized portions of leasing commissions and lease intangibles associated with that lease are written off to amortization expense or rental revenue, respectively, as further described below.

88

Depreciation on buildings is generally provided on a straight-line basis over 40 years from the date the buildings were placed in service. Building components are depreciated over the life of the respective improvement ranging from 10 to 40 years from the date the components were placed in service. Personal property is depreciated over three years to seven years. Depreciation expense was $103.5 million, $98.8 million and $92.3 million for the years ended December 31, 2016, 2015 and 2014, respectively. Repairs and maintenance costs are expensed as incurred.

We review each of our properties for indicators of impairment. 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, a significant adverse change in legal factors or in the business climate that could affect the value of a property, including an adverse action or assessment by a regulator, an accumulation of costs significantly in excess of the amount originally expected for the development of a property, a history of operating or cash flow losses of the property or a current expectation that, more likely than not, a property will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. When such impairment indicators exist, we review an estimate of the future undiscounted net cash flows 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 assess the recoverability of the carrying value of our assets on a property-by-property basis. 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 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.

No impairment losses were recorded for the years ended December 31, 2016 and 2014. In the fourth quarter of 2015, we identified our NJ1 data center as an asset that fell outside of our strategic focus on wholesale data centers in our targeted markets, and it became evident that we would, more likely than not, sell NJ1 prior to its previously estimated useful life. In connection with that determination, we evaluated the recoverability of the carrying value for NJ1 and determined that its carrying value was no longer recoverable due to reducing its expected holding period. As a result, for the year ended December 31, 2015, we reduced the carrying value of NJ1 to its estimated fair value by recording an impairment charge of $122.5 million. Estimated fair value was determined using a third party appraisal for NJ1 in conjunction with the guidance in ASC 820, which involved the use of Level 3 inputs. The appraisal was based on the income capitalization approach which derives value using the property's potential income and an average market capitalization rate for comparable sales in the market. NJ1 was sold in the second quarter of 2016 at a gain of $22.8 million.

We classify a data center property as held-for-sale when it meets the necessary criteria, which include when we commit to and actively embark on a plan to sell the asset, the sale is expected to be completed within one year under terms usual and customary for such sales, and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Data center properties held-for-sale are carried at the lower of cost or fair value less costs to sell. Accordingly, as of December 31, 2016 and 2015, we did not have any properties classified as held-for-sale.

Cash and Cash Equivalents

We consider all demand deposits and money market accounts purchased with a maturity date of three months or less, at the date of purchase, to be cash equivalents. Our account balances at one or more institutions exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. We have not experienced any losses and believe that the risk is not significant.

Deferred Costs

Deferred costs, net in our accompanying consolidated balance sheets include both financing and leasing costs.

Financing costs, which represent fees and other costs incurred in obtaining debt, are amortized using the effective-interest rate method, or a method that approximates the effective-interest method, over the term of the loan and are included in amortization of deferred financing costs.

Balances of financing costs for our unsecured revolving credit facility (the "Unsecured Credit Facility"), net of accumulated amortization, which are presented within deferred costs, net in our accompanying consolidated balance sheets at December 31, 2016 and 2015, are as follows (in thousands):

	December 31,
Financing costs presented within deferred costs, net	2016			2015
Financing costs	$	12,352		$	8,198
Accumulated amortization	(6,376		)	(4,969		)
Financing costs, net	$	5,976		$	3,229

Balances of financing costs for our other recognized debt liabilities, net of accumulated amortization, which are presented as a reduction of each of the respective recognized debt liabilities in our accompanying consolidated balance sheets at December 31, 2016 and 2015, are as follows (in thousands):

	December 31,
Financing costs presented as a reduction of debt liability balances	2016			2015

Accumulated amortization	(7,935		)	(5,618		)
Financing costs, net	$	12,488		$	14,913

On July 25, 2016, we amended and restated the Unsecured Credit Facility and the Unsecured Term Loan, which, due to the change in composition of lenders comprising the Unsecured Credit Facility's bank group, resulted in a loss on early extinguishment of debt of $1.2 million in the third quarter of 2016, which included a partial write-off of unamortized deferred financing costs of $0.5 million. In May 2014, we amended the Unsecured Credit Facility, which, due to the change in composition of lenders comprising the Unsecured Credit Facility's bank group, resulted in the partial write-off of unamortized deferred financing costs totaling $0.3 million. In July 2014, we amended the Unsecured Term Loan, which, due to the change in composition of lenders comprising the Unsecured Term Loan's bank group, resulted in a loss on early extinguishment of debt of $1.4 million, which included a partial write-off of unamortized deferred financing costs of $0.7 million.

Leasing costs, which consist of external fees and costs incurred in the successful negotiation of leases, internal costs expended in the successful negotiation of leases and the estimated leasing commissions resulting from the allocation of the purchase price of ACC2, VA3, VA4 and ACC4, are deferred and amortized over the terms of the applicable leases on a straight-line basis. If an applicable lease terminates prior to the expiration of its initial term, the carrying amount of the leasing costs are written off to amortization expense. In June 2015, we wrote off $0.7 million of unamortized leasing costs to amortization expense related to a former customer in bankruptcy whose leases with us were rejected effective July 1, 2015 pursuant to an order made by the bankruptcy court, described below.

Leasing costs incurred for the years ended December 31, 2016, 2015 and 2014 are as follows (in thousands):

	Year ended December 31,
	2016		2015		2014
Costs incurred for new leases	$	3,690	$	2,096	$	2,004
Costs incurred for renewals	202		1,188		153
Costs incurred for re-leases	—		949		2,000
Total leasing costs incurred	$	3,892	$	4,233	$	4,157

Amortization of deferred leasing costs totaled $4.2 million, $4.9 million and $4.1 million for the years ended December 31, 2016, 2015 and 2014, respectively. Balances, net of accumulated amortization, at December 31, 2016 and 2015 are as follows (in thousands):

Inventory

We maintain fuel inventory for our generators, which is recorded at the lower of cost (on a first-in, first-out basis) or market. As of December 31, 2016 and 2015, the fuel inventory was $4.2 million and $4.5 million, respectively, and is included in prepaid expenses and other assets in the accompanying consolidated balance sheets.

Prepaid Rents

Prepaid rents, typically prepayment of the following month’s rent, consist of payments received from customers prior to the time the payments are earned and are recognized as revenue in subsequent periods when earned.

Rental Income

We, as a lessor, have retained substantially all the risks and benefits of ownership and account for our leases as operating leases. For lease agreements that provide for scheduled fixed and determinable rent increases, rental income is recognized on a straight-line basis over the non-cancellable term of the lease, which commences when control of the space and critical power have been provided to the customer. If the lease contains an early termination clause with a penalty payment, we determine the lease termination date by evaluating whether the penalty reasonably assures that the lease will not be terminated early.

Straight-line rents receivable are included in deferred rent, net in the accompanying consolidated balance sheets. Lease inducements, which include cash payments to customers, are amortized as a reduction of rental income over the noncancellable lease term. Lease inducements are included in prepaid expenses and other assets in the accompanying consolidated balance sheets. Lease intangible assets and liabilities that have resulted from above market and below market leases that were acquired are amortized on a straight-line basis as decreases and increases, respectively, to rental revenue over the remaining non-cancellable term of the underlying leases.

If a lease terminates prior to the expiration of its initial term, the unamortized portion of straight-line rents receivable, lease inducements and lease intangibles associated with that lease will be written off to rental revenue. In June 2015, we wrote-off as a reduction of base rent $0.4 million of unreserved straight-line rents receivable, $0.1 million of unamortized lease inducements and $1.0 million of unamortized lease intangibles related to a former customer in bankruptcy whose leases with us were rejected effective July 1, 2015 pursuant to an order made by the bankruptcy court.

Balances, net of accumulated amortization, at December 31, 2016 and 2015 are as follows (in thousands):

	December 31,
	2016			2015
Lease contracts above market value	$	20,500		$	20,500
Accumulated amortization	(15,362		)	(14,471		)
Lease contracts above market value, net	$	5,138		$	6,029
Lease contracts below market value	$	24,175		$	24,175
Accumulated amortization	(21,345		)	(20,043		)
Lease contracts below market value, net	$	2,830		$	4,132

Our policy is to record an allowance for losses on accounts receivable equal to the estimated uncollectible accounts. The estimate is based on our historical experience and a review of the current status of our receivables. As of December 31, 2016, we had a note receivable from a former customer of $25.0 million, which resulted from the settlement of our claim in this former customer's bankruptcy proceedings in the fourth quarter of 2016 and replaced the $6.5 million note receivable that we had from this former customer as of December 31, 2015. We are accounting for the note receivable on a non-accrual basis. As of December 31, 2016 and 2015, we had allowances against these notes of $23.6 million and $5.1 million, respectively, leaving a note receivable, net, of $1.4 million as of December 31, 2016 and 2015, which is included within rents and other receivables, net in our accompanying consolidated balance sheets. Based on the principal payment schedule in the note that includes semiannual principal payments beginning in June 2017, we continue to be reasonably assured that we will be able to collect the balance of the note receivable, net.

We also establish an appropriate allowance for doubtful accounts for receivables arising from the straight-lining of rents. These receivables arise from revenue recognized in excess of amounts currently due under the lease and are recorded as deferred rent in the accompanying consolidated balance sheets. As of December 31, 2016 and 2015, we had no material allowances.

91

Our customer leases generally contain provisions under which the customers reimburse us for a portion of operating expenses and real estate taxes incurred by the property. Recoveries from tenants are included in revenue in the accompanying consolidated statements of operations in the period the applicable expenditures are incurred. The majority of our customer leases also provide us with a property management fee based on a percentage of base rent collected and property-level operating expenses, other than charges for power used by customers to run their servers and cool their space. Property management fees are included in base rent in the accompanying consolidated statements of operations in the applicable period in which they are earned.

Other Revenue

Other revenue primarily consists of services provided to customers on a non-recurring basis. This includes layout design and installation of electrical power circuits, data cabling, server cabinets and racks, computer room airflow analyses and monitoring and other services requested by customers. Revenue is recognized on a completed contract basis when the project is finished and ready for the customer's use. This method is consistently applied for all periods presented. Costs of providing these services are included in other expenses in the accompanying consolidated statements of operations.

Income Taxes

DFT elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), commencing with the taxable year ended December 31, 2007. In general, a REIT that meets certain organizational and operational requirements and distributes at least 90 percent of its REIT taxable income to its shareholders in a year will not be subject to income tax to the extent of the income it distributes. We currently qualify and intend to continue to qualify as a REIT under the Code. As a result, no provision for federal income taxes on income from continuing operations is required, except for taxes on certain property sales and on income, if any, of DF Technical Services, LLC, our taxable REIT subsidiary (“TRS”). If we fail to qualify as a REIT in any taxable year, we will be subject to federal income tax (including any applicable alternative minimum tax) on our income at regular corporate tax rates for the year in which we do not qualify and the succeeding four years. Although we expect to qualify for taxation as a REIT, we may be subject to state and local income and franchise taxes and to federal income and excise taxes on any undistributed income.

As of December 31, 2016 and 2015, we did not have any unrecognized tax benefits. We do not believe that there will be any material changes in our unrecognized tax positions over the next 12 months. We are subject to examination by the respective taxing authorities for the tax years 2013 through 2016.

In general, a TRS may perform non-customary services for customers, hold assets that DFT cannot hold directly and generally may engage in any real estate or non real estate-related business. A TRS is subject to corporate federal and state income taxes on its taxable income at regular statutory tax rates. For the years ended December 31, 2016 and 2014, we incurred $0.1 million of income taxes. For the year ended December 31, 2015, we incurred no income taxes; however, we recorded a deferred income tax credit of $0.2 million to reverse the cumulative deferred tax expense recorded as of December 31, 2014.

We account for income taxes using the asset and liability method under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Valuation allowances are provided if, based upon the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

As of December 31, 2016, our TRS had a deferred tax asset of $0.2 million, comprised entirely of its net operating loss carryforward, and no deferred tax liability, resulting in a net deferred tax asset of $0.2 million. We recorded a full valuation allowance for this net deferred tax asset as of December 31, 2016 due to the uncertainty of the realizability of this asset. The net operating loss carryforward of $0.2 million will begin to expire in 2031 if not utilized by then.

As of December 31, 2015, our TRS had a deferred tax asset of $4.6 million, comprised entirely of its net operating loss carryforward, and a deferred tax liability of $2.3 million, primarily comprised of a temporary depreciation difference, resulting in a net deferred tax asset of $2.3 million. We recorded a full valuation allowance for this net deferred tax asset as of December 31, 2015 due to the uncertainty of the realizability of this asset.

Redeemable Noncontrolling Interests – Operating Partnership / Redeemable Partnership Units

Redeemable noncontrolling interests – operating partnership, as presented on DFT’s consolidated balance sheets, represent the limited partnership interests in the Operating Partnership (the “OP units”) held by individuals and entities other than DFT. These interests are also presented on the Operating Partnership’s consolidated balance sheets, referred to as

92

“redeemable partnership units.” Accordingly, the following discussion related to redeemable noncontrolling interests – operating partnership of DFT refers equally to redeemable partnership units of the Operating Partnership.

Redeemable noncontrolling interests – operating partnership, which require cash payment, or allow settlement in shares, but with the ability to deliver the shares outside of the control of DFT, are reported outside of the permanent equity section of the consolidated balance sheets of DFT and the Operating Partnership. Redeemable noncontrolling interests – operating partnership are adjusted for income, losses and distributions allocated to OP units not held by DFT (normal noncontrolling interest accounting amount). Adjustments to redeemable noncontrolling interests – operating partnership are recorded to reflect increases or decreases in the ownership of the Operating Partnership by holders of OP units, including the redemptions of OP units for cash or in exchange for shares of DFT’s common stock. If such adjustments result in redeemable noncontrolling interests – operating partnership being recorded at less than the redemption value of the OP units, redeemable noncontrolling interests – operating partnership are further adjusted to their redemption value. See Note 9. Redeemable noncontrolling interests – operating partnership are recorded at the greater of the normal noncontrolling interest accounting amount or redemption value. The following is a summary of activity for redeemable noncontrolling interests – operating partnership for the years ended December 31, 2016, 2015 and 2014 (dollars in thousands):

Earnings Per Share of DFT

Basic earnings per share is calculated by dividing the net income attributable to common shares for the period by the weighted average number of common shares outstanding during the period using the two class method. Diluted earnings per share is calculated by dividing the net income attributable to common shares for the period by the weighted average number of common and dilutive securities outstanding during the period using the two class method.

Earnings Per Unit of the Operating Partnership

Basic earnings per unit is calculated by dividing the net income attributable to common units for the period by the weighted average number of common units outstanding during the period using the two class method. Diluted earnings per unit is calculated by dividing the net income attributable to common units for the period by the weighted average number of common and dilutive securities outstanding during the period using the two class method.

Stock-based Compensation

We periodically award stock-based compensation to employees and members of our Board of Directors in the form of common stock, restricted common stock, options and performance units. For each common stock award granted by DFT, the OP issues an equivalent common unit, which may be referred to herein as a common share, common stock, or a common unit. We estimate the fair value of the awards and recognize this value over the requisite service period. The fair value of restricted stock-based compensation is based on the market value of DFT’s common stock on the date of the grant. The fair value of options to purchase common stock is based on the Black-Scholes model. The fair value of performance units is based on a Monte Carlo simulation. Forfeitures of all stock-based compensation awards are recognized as they occur.

Compensation paid with Company common shares, which is included in general and administrative expense on our consolidated statements of operations, totaled $6.6 million, $5.3 million and $6.2 million for the years ended December 31, 2016, 2015 and 2014, respectively. We capitalized $0.9 million, $0.8 million and $0.7 million of compensation paid with Company common shares to our data centers under development for the years ended December 31, 2016, 2015 and 2014, respectively.

Foreign Currency

The U.S. dollar is the functional currency of our consolidated operations in the United States. The functional currency of our consolidated entities that operate outside of the United States is the principal currency of the economic environment in which the entity primarily generates and expends cash. We translate the financial statements of consolidated entities whose functional currency is not the U.S. dollar into U.S. dollars. We translate assets and liabilities at the exchange rate in effect as of the financial statement date and translate income statement accounts using the weighted average exchange rate for the period. We include foreign currency translation adjustments and the effect of exchange rate changes on intercompany transactions of a long-term investment nature as a separate component of stockholders' equity or partners' capital. We report gains and losses from the effect of rate changes on intercompany receivables and payables that are not of a long-term investment nature, as well as gains and losses from remeasuring U.S. dollar transactions for non-U.S. functional currency entities, in other expenses on our consolidated statements of operations. For the year ended December 31, 2016, we had less than $0.1 million of foreign currency transaction losses.

Recently Issued Accounting Pronouncements

Revenue Recognition - In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update No. 2014-09, Revenue from Contracts with Customers (Topic 606). The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. We are required to apply the new standard in the first quarter of 2018 and expect to elect the modified retrospective method of application of the standard. Although the standard does not apply to leases, we have assessed the impact on our financial position and results of operations. The standard will change our method of recognizing revenue on service and installation contracts included in other revenue in the accompanying consolidated statements of operations from the completed contract method to a method that recognizes revenue over the course of the contract based on the goods or services transferred to date relative to the remaining goods or services promised under the contract. We do not expect that this change will have a material effect on our financial position or results of operations. In addition, we currently do not believe the standard will have a material impact on how we recognize revenues from tenants with respect to operating expense recoveries on our financial position or results of operations.

Leases - In February 2016, the FASB issued Accounting Standards Update No. 2016-02 - Leases (Topic 842). We are required to apply the new standard in the first quarter of 2019. The Company’s leases consist of both lease components that will be accounted for under this standard and non-lease components such as operating expense recovery income that will be accounted for under ASU 2014-09, Revenue from Contracts with Customers. The standard does not fundamentally change the lessor accounting model, and we do not believe that the new standard will have a material impact on our financial position or results of operations.

Financial Instruments - In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. Under this guidance, a company will be required to use a new forward-looking "expected loss" model for trade and other receivables that generally will result in the earlier recognition of allowances for losses. We are required to apply the new standard in the first quarter of 2020 and do not believe that the new standard will have a material effect on our financial position or results of operations.

Statement of Cash Flows - In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. The standard provides guidance on eight specific cash flow classification issues including debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, and separately identifiable cash flows and application of the predominance principle. We are required to apply the new standard in the first quarter of 2018 and do not believe that the new standard will have a material effect on our financial position or results of operations.

Statement of Cash Flows - Restricted Cash - In November 2016, the FASB issued Accounting Standards Update No. 2016-18 (Topic 230), Restricted Cash. The standard requires restricted cash to be included with cash and cash equivalents when reconciling the beginning and ending amounts in the statement of cash flows. We are required to apply the new standard in the first quarter of 2018 and do not believe that the new standard will have a material effect on our financial position or results of operations.

95

Business Combinations - In January 2017, the FASB issued Accounting Standards Update No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The standard narrows the existing definition of a business and provides a framework for evaluating whether a transaction should be accounted for as an acquisition of assets or a business. The guidance is effective for public entities for fiscal years beginning after December 15, 2017 and interim periods within those years. However, we will early-adopt the standard effective January 1, 2017. As a result of this new guidance, acquisitions may now result in an asset purchase rather than a business combination. We do not believe that the new standard will have a material effect on our financial position or results of operations.

Recently Adopted Accounting Pronouncements

Going Concern - In August 2014, the FASB issued Accounting Standards Update No. 2014-15 - Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. Under this guidance, management is required to perform a going concern evaluation similar to the auditor's evaluation required by standards issued by the Public Company Accounting Oversight Board and the American Institute of Certified Public Accountants. This evaluation is required for both annual and interim reporting periods. We adopted the new standard in the fourth quarter of 2016, and there was no material effect on our financial position or results of operations.

Consolidation - In February 2015, the FASB issued Accounting Standards Update No. 2015-02 - Consolidation: Amendments to the Consolidation Analysis, which amends the criteria for determining variable interest entities (“VIEs”), amends the criteria for determining if a service provider possesses a variable interest in a VIE, and eliminates the presumption that a general partner should consolidate a limited partnership. We adopted this standard as of January 1, 2016, and there was no material effect on our financial position or results of operations.

Stock Compensation - In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The new guidance affects two areas of our accounting. First, the guidance increases the amount an employer can withhold to cover income taxes on awards and still qualify for the exception to liability classification for shares used to satisfy the employer's statutory income tax withholding obligation. An employer is now allowed to withhold shares up to the amount of tax potentially owed using the maximum statutory tax rate in each jurisdiction. Second, companies now have the ability to make a policy election to account for forfeitures as they occur versus recording a forfeiture estimate. We early-adopted this standard as of January 1, 2016 and elected to account for forfeitures as they occur versus recording a forfeiture estimate. Per the guidance, we used a modified retrospective transition method of adoption, with a cumulative effect adjustment to accumulated deficit on our consolidated balance sheet as of December 31, 2015 totaling less than $0.1 million (see below).

Change in Accounting Principle

Stock Compensation - As required by Accounting Standards Update No. 2016-09 issued in March 2016, described above, we made a cumulative-effect adjustment to accumulated deficit to eliminate the forfeiture estimate recorded as of December 31, 2015, with a corresponding adjustment to additional paid in capital. The following table presents the prior period amounts that have been impacted by the new guidance and retrospectively adjusted on the consolidated balance sheet as of December 31, 2015 for DFT (dollars in thousands):

	As of December 31, 2015
	As Previously Reported			Impact of Change in Accounting Principle			As Adjusted and Currently Reported
Additional paid in capital	$	684,968		$	74		$	685,042
Accumulated deficit	(79,871		)	(74		)	(79,945		)

Because the consolidated balance sheet for the Operating Partnership includes capital accounts for the general partner and the limited partners, which each include a combination of partner capital and retained earnings (accumulated deficit), there was no adjustment required for the consolidated balance sheet for the Operating Partnership as of December 31, 2015.

The other parcel is an 8.6 acre site that we purchased for $4.6 million. This parcel is being held for the future development of either a powered base shell or build-to-suit data center to be known as ACC11.

In June 2016, we completed the sale of our NJ1 data center for a gross purchase price of $125.0 million, and recorded a gain on sale of $22.8 million. We had previously recorded an impairment charge of $122.5 million during the fourth quarter of 2015.

In July 2016, we completed the acquisition of a 46.7 acre parcel of land in Hillsboro, Oregon for a purchase price of $11.2 million. This acquisition was treated as an asset purchase under GAAP. We are holding this parcel of land for future development in connection with our expansion plans.

In September 2016, we completed the acquisition of a shell building and associated land in Vaughan, Ontario for a purchase price of $54.3 million CAD ($41.6 million USD). This acquisition was treated as an asset purchase under GAAP. We are currently developing Phase I of TOR1 in this shell.

Outstanding Indebtedness

Unsecured Credit Facility and Unsecured Term Loan

On July 25, 2016, we entered into an amended and restated credit agreement with a syndicate of banks (the "Amended and Restated Credit Agreement") that includes the following:

• an unsecured revolving credit facility with a total commitment of $750 million (the "Unsecured Credit Facility"); and

• an unsecured term loan facility, which has a total commitment and amount outstanding of $250 million (the "Unsecured Term Loan").

In November 2016, we added a Canadian dollar sublimit of up to $185 million (approximately CAD $250 million) to the Unsecured Credit Facility, which allows us to borrow in Canadian dollars to fund our TOR1 data center development in Vaughan, Ontario. In addition, the Canadian borrowings allow us to hedge our foreign currency investment risk by having these liabilities translate at the same exchange rates as our Canadian assets at the end of each period. In 2016, we designated all of the Canadian borrowings on our Unsecured Credit Facility, which totaled CAD $62.0 million as of December 31, 2016, as a net investment hedge of our Canadian assets. For the effective portion of these net investment hedges, the currency translation effects of these borrowings are reflected in accumulated other comprehensive loss within shareholders' equity on our consolidated balance sheets, where they offset the currency translation effects of our investment in our Canadian assets. There was no ineffectiveness for our net investment hedges during 2016.

At our option, we may increase the total commitment under the Unsecured Credit Facility and the Unsecured Term Loan to $1.25 billion, if one or more lenders commit to being a lender for the additional amount and certain other customary conditions are met.

Prior to July 25, 2016, the Unsecured Credit Facility and the Unsecured Term Loan were outstanding under separate credit agreements.

The obligations under the Amended and Restated Credit Agreement are unconditionally guaranteed, jointly and severally, on a senior unsecured basis by DFT and all of the Operating Partnership’s subsidiaries that currently guaranty the obligations under the Unsecured Notes due 2021, listed below. Prior to July 25, 2016, the separate credit agreements that governed the Unsecured Credit Facility and the Unsecured Term Loan provided for substantially the same guarantees as the Amended and

100

Restated Credit Agreement. We may prepay the Unsecured Credit Facility and the Unsecured Term Loan at any time, in whole or in part, without penalty or premium.

The Amended and Restated Credit Agreement requires that DFT, the Operating Partnership and their subsidiaries comply with various covenants, including with respect to restrictions on liens, incurring indebtedness, making investments, effecting mergers and/or asset sales, and certain limits on dividend payments, distributions and purchases of DFT's stock. In addition, the facility imposes financial maintenance covenants relating to, among other things, the following matters:

• unsecured debt not exceeding 60% of the value of unencumbered assets, subject to an increase up to 65% following a material acquisition;

• net operating income generated from unencumbered properties divided by the amount of unsecured debt (net of unrestricted cash and cash equivalents) being not less than 12.5%, subject to a decrease to not less than 10.0% following a material acquisition;

• total indebtedness not exceeding 60% of gross asset value, subject to an increase up to 65% following a material acquisition;

• fixed charge coverage ratio being not less than 1.70 to 1.00;

• tangible net worth being not less than $2.3 billion plus 75% of the sum of (i) net equity offering proceeds after July 25, 2016 (but excluding such net offering proceeds that are used within ninety (90) days following the consummation of the applicable equity offering for permitted equity redemptions) and (ii) the value of equity interests issued in connection with a contribution of assets to the borrower or its subsidiaries; and

• until an investment grade unsecured debt credit rating has been achieved, unhedged variable rate debt not exceeding 30% of gross asset value.

The Amended and Restated Credit Agreement includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest and other obligations of the Operating Partnership under the facility to be immediately due and payable.

We were in compliance with all covenants under the Unsecured Credit Facility and the Unsecured Term Loan as of December 31, 2016.

The Unsecured Credit Facility matures on July 25, 2020.

We may elect to have borrowings under the Unsecured Credit Facility bear interest at either the London Interbank Offered Rate (“LIBOR”) or a base rate, which is based on the lender's prime rate, in each case plus an applicable margin. Prior to our receiving an investment grade credit rating, the applicable margin added to LIBOR and the base rate is based on the table below.

		Applicable Margin
Pricing Level	Ratio of Total Indebtedness to Gross Asset Value	LIBOR Rate Loans		Base Rate Loans
Level 1	Less than or equal to 35%	1.55	%	0.55	%
Level 2	Greater than 35% but less than or equal to 40%	1.65	%	0.65	%
Level 3	Greater than 40% but less than or equal to 45%	1.80	%	0.80	%
Level 4	Greater than 45% but less than or equal to 52.5%	1.95	%	0.95	%
Level 5	Greater than 52.5%	2.15	%	1.15	%

The applicable margin is currently set at pricing Level 1. The terms of the Unsecured Credit Facility provide for the adjustment of the applicable margin from time to time according to the ratio of the Operating Partnership’s total indebtedness to gross asset value in effect from time to time.

In the event we receive an investment grade credit rating, borrowings under the Unsecured Credit Facility will bear interest based on the table below.

101

		Applicable Margin
Credit Rating Level	Credit Rating	LIBOR Rate Loans		Base Rate Loans
Level 1	Greater than or equal to A- by S&P or A3 by Moody’s	0.85	%	0.00	%
Level 2	Greater than or equal to BBB+ by S&P or Baa1 by Moody’s	0.90	%	0.00	%
Level 3	Greater than or equal to BBB by S&P or Baa2 by Moody’s	1.00	%	0.00	%
Level 4	Greater than or equal to BBB- by S&P or Baa3 by Moody’s	1.20	%	0.20	%
Level 5	Less than BBB- by S&P or Baa3 by Moody’s	1.55	%	0.55	%

Following the receipt of such investment grade rating, the terms of the Unsecured Credit Facility provide for the adjustment of the applicable margin from time to time according to the rating then in effect.

The amount available for borrowings under the Unsecured Credit Facility is determined according to a calculation comparing the value of certain unencumbered properties designated by the Operating Partnership at such time relative to the amount of the Operating Partnership's unsecured debt. Up to $35 million of the borrowings under the Unsecured Credit Facility may be used for letters of credit.

As of December 31, 2016, we had no letters of credit outstanding. As of December 31, 2016, we had USD $10.0 million and CAD $55.0 million outstanding on the Unsecured Credit Facility for a total of USD $50.9 million outstanding. As of February 23, 2017, we had USD $60.0 million and CAD $62.0 million outstanding on the Unsecured Credit Facility for a total of approximately USD $107.1 million outstanding.

The Unsecured Term Loan matures on January 21, 2022.

Under the terms of the Unsecured Term Loan, we may elect to have borrowings under the loan bear interest at either LIBOR or a base rate, which is based on the lender's prime rate, in each case plus an applicable margin. Prior to our receiving an investment grade credit rating, the applicable margin added to LIBOR and the base rate is based on the table below.

		Applicable Margin
Pricing Level	Ratio of Total Indebtedness to Gross Asset Value	LIBOR Rate Loans		Base Rate Loans
Level 1	Less than or equal to 35%	1.50	%	0.50	%
Level 2	Greater than 35% but less than or equal to 40%	1.60	%	0.60	%
Level 3	Greater than 40% but less than or equal to 45%	1.75	%	0.75	%
Level 4	Greater than 45% but less than or equal to 52.5%	1.90	%	0.90	%
Level 5	Greater than 52.5%	2.10	%	1.10	%

The applicable margin is currently set at pricing Level 1. The terms of the Unsecured Term Loan also provide that, in the event we receive an investment grade credit rating, borrowings under the loan will bear interest based on the table below.

		Applicable Margin
Credit Rating Level	Credit Rating	LIBOR Rate Loans		Base Rate Loans
Level 1	Greater than or equal to A- by S&P or A3 by Moody’s	0.825	%	0.00	%
Level 2	Greater than or equal to BBB+ by S&P or Baa1 by Moody’s	0.875	%	0.00	%
Level 3	Greater than or equal to BBB by S&P or Baa2 by Moody’s	1.00	%	0.00	%
Level 4	Greater than or equal to BBB- by S&P or Baa3 by Moody’s	1.25	%	0.25	%
Level 5	Less than BBB- by S&P or Baa3 by Moody’s	1.65	%	0.65	%

Following the receipt of such investment grade rating, the terms of the loan provide for the adjustment of the applicable margin from time to time according to the rating then in effect.

ACC3 Term Loan

We have a $111.3 million term loan facility that is secured by our ACC3 data center facility and an assignment of the lease agreement between us and the customer of ACC3 (the "ACC3 Term Loan"). The borrower, one of our subsidiaries, may elect to have borrowings under the ACC3 Term Loan bear interest at (i) LIBOR plus 1.55% or (ii) a base rate, which is based on the lender's prime rate, plus 0.55%. The interest rate is currently at LIBOR plus 1.55%. The ACC3 Term Loan matures on

102

March 27, 2018, and we may prepay the ACC3 Term Loan at any time, in whole or in part, without penalty or premium. The Operating Partnership has guaranteed the outstanding principal amount of the ACC3 Term Loan, plus interest and certain costs under the loan.

The ACC3 Term Loan imposes financial maintenance covenants relating to, among other things, the following matters:

• consolidated total indebtedness of the Operating Partnership not exceeding 60% of gross asset value of the Operating Partnership;

• fixed charge coverage ratio of the Operating Partnership being not less than 1.70 to 1.00;

• tangible net worth of the Operating Partnership being not less than $1.3 billion plus 80% of the sum of (i) net equity offering proceeds and (ii) the value of equity interests issued in connection with a contribution of assets to the Operating Partnership or its subsidiaries; and

• debt service coverage ratio of the borrower not less than 1.50 to 1.00.

We were in compliance with all of the covenants under the ACC3 Term Loan as of December 31, 2016.

Unsecured Notes due 2021

On September 24, 2013, the Operating Partnership completed the sale of $600 million of 5.875% senior unsecured notes due 2021, which we refer to as the Unsecured Notes due 2021.

The ranking of the Unsecured Notes due 2023 and the guarantees of these notes are the same as the ranking of the Unsecured Notes due 2021 and the guarantees of those notes.

At any time prior to June 15, 2018, the Operating Partnership may redeem the Unsecured Notes due 2023, in whole or in part, at a price equal to the sum of (i) 100% of the principal amount of the Unsecured Notes due 2023 to be redeemed, plus (ii) a make-whole premium and accrued and unpaid interest.

7. Related Party Transactions

We leased space for our headquarters building from an affiliate of our Chairman of the Board and our former CEO. In addition, our Executive Vice President, Chief Development Officer, is a non-managing member of this entity, and her sole interest is an approximately 1% non-managing membership interest. Rent expense was $0.3 million, $0.4 million and $0.4 million for each of the years ended December 31, 2016, 2015 and 2014. This lease ended on September 30, 2016 and we have entered into a new office lease with an unrelated party.

In February 2016, we acquired two parcels of undeveloped land in Ashburn, Virginia, from entities controlled by our Chairman of the Board. One parcel is a 35.4 acre site that we purchased for $15.6 million, which we are using for the development of our ACC9 and ACC10 data center facilities. The managers of the entity that sold us this site are a limited liability company owned solely by our Chairman of the Board, which also owns approximately 7% of the seller, and a limited liability company owned solely by our former CEO which also owns approximately 1% of the seller. In connection with the purchase of this parcel, the parties agreed that the party who began improvement work first on any portion of the property that is adjacent to the road would be responsible for certain improvements to the road required by the county and that the cost of these improvements would be shared between the parties. We were the first to begin improvements to the land adjacent to the road, and we have begun to make the necessary improvements to the road as required. As of December 31, 2016, $0.3 million was due to us from the seller for its share of these improvement costs.

The other parcel is an 8.6 acre site that we purchased for $4.6 million. This parcel is being held for the future development of either a powered base shell or build-to-suit data center to be known as ACC11. Our Chairman of the Board and our former CEO are the managers of the limited liability company that manages the entity that sold us this site. Our Chairman of the Board directly and indirectly owns approximately 23% of the seller, and our former CEO directly and indirectly owns approximately 18% of the seller. In addition, Frederic V. Malek, one of our independent directors, is a non-managing member of the entity that owned this site. Mr. Malek’s sole interest in this entity is the ownership of an approximately 4% non-managing membership interest; he is neither an employee nor an executive officer of this entity. The purchase price for each site was based on an appraisal prepared for the Audit Committee of our Board of Directors by an independent appraisal firm.

8. Commitments and Contingencies

We are involved from time to time in various legal proceedings, lawsuits, examinations by various tax authorities and claims that have arisen in the ordinary course of business. We currently believe that the resolution of such matters will not have a material adverse effect on our financial condition or results of operations.

105

Contracts related to the development of ACC7 Phase IV, ACC9 Phases I-II, SC1 Phase III, CH3 Phase I and ACC10 data centers were in place as of December 31, 2016. These contracts are cost-plus in nature whereby the contract sum is the aggregate of the contractor's cost to perform the work and to purchase the equipment plus a contractor fee. Control estimates, which are adjusted from time to time to reflect any contract changes, are estimates of the total contract cost at completion. As of December 31, 2016, the control estimates were as follows for our projects under development:

• ACC7 Phase IV: $33.3 million of which $31.7 million had been incurred, and an additional $0.1 million has been committed under this contract.

• ACC9 Phase I: $168.4 million of which $126.9 million has been incurred, and an additional $23.5 million has been committed under this contract.

• ACC9 Phase II: $63.9 million of which $5.2 million has been incurred, and an additional $31.0 million has been committed under this contract.

• SC1 Phase III: $149.0 million of which $78.6 million has been incurred, and an additional $17.1 million has been committed under this contract.

• CH3 Phase I: $190.7 million of which $6.0 million has been incurred, and an additional $35.4 million has been committed under this contract.

• ACC10 shell: $52.1 million of which $0.1 million has been incurred, and an additional $2.3 million has been committed under this contract.

Concurrent with DFT’s October 2007 initial public offering, we entered into tax protection agreements with some of the contributors of the initial properties including our Chairman of the Board and our former CEO. Pursuant to the terms of these agreements, if we dispose of any interest in the initial contributed properties that generates more than a certain allowable amount of built-in gain for the contributors, as a group, in any single year through 2017, we will indemnify the contributors for a portion of the tax liabilities incurred with respect to the amount of built-in gain and tax liabilities incurred as a result of the reimbursement payment. The amount of initial built-in gain that can be recognized as of January 1, 2017 without triggering the tax protection provisions is approximately 100% of the initial built-in gain of $667 million (unaudited). This percentage has increased each year by 10%, accumulating to 100% in 2017. As of December 31, 2016, none of the tax protection provisions have been triggered and no liability has been recorded on our consolidated balance sheet. If, as of January 1, 2017, the tax protection provisions were triggered, we would not be liable for protection on the taxes related to the built-in gain. Additionally, pursuant to the terms of these agreements, we must provide an opportunity for certain of the contributors of the initial properties to guarantee a secured loan and, if we fail to do so, we could be liable for protection on the taxes related to approximately $57 million (unaudited) of remaining minimum liability. The amount of our liability for protection on taxes could be based on the highest federal, state and local capital gains tax rates of the applicable contributor. Any sale by the Company that requires payments to any of DFT’s executive officers or directors pursuant to these agreements requires the approval of at least 75% of the disinterested members of DFT’s Board of Directors.

9. Redeemable noncontrolling interests – operating partnership / Redeemable partnership units

Redeemable noncontrolling interests – operating partnership, as presented in DFT’s accompanying consolidated balance sheets, represent the OP units held by individuals and entities other than DFT. These interests are also presented in the Operating Partnership’s consolidated balance sheets, referred to as “redeemable partnership units.” Accordingly, the following discussion related to redeemable noncontrolling interests – operating partnership of DFT refers equally to redeemable partnership units of the Operating Partnership.

The redemption value of redeemable noncontrolling interests – operating partnership as of December 31, 2016 and December 31, 2015 was $591.1 million and $479.2 million, respectively, based on the closing share price of DFT’s common stock of $43.93 and $31.79, respectively, on those dates.

Holders of OP units are entitled to receive distributions in a per unit amount equal to the per share dividends made with respect to each share of DFT’s common stock, if and when DFT’s Board of Directors declares such a dividend. Holders of OP units have the right to tender their units for redemption, in an amount equal to the fair market value of DFT’s common stock. DFT may elect to redeem tendered OP units for cash or for shares of DFT’s common stock. During the years ended December 31, 2016, 2015 and 2014 OP unitholders redeemed a total of 1,618,048, 363,674, and 234,300 OP units, respectively, in exchange for an equal number of shares of common stock. See Note 2.

In December 2014, the Board of Directors approved a common stock repurchase program to acquire up to $120.0 million of DFT's common shares in 2015. Under this program, which expired on December 31, 2015, DFT repurchased 1,002,610 shares of its common stock totaling $31.9 million. All repurchased shares were retired immediately, and the Operating Partnership retired an equivalent number of units. We did not have a repurchase program in 2016.

In March 2016, DFT completed a secondary underwritten public offering of 7,613,000 shares of common stock, at a public offering price of $37.75 per share. The total shares sold included 993,000 shares of common stock pursuant to the full exercise of the underwriters’ option to purchase additional shares of common stock. Net proceeds from the offering were approximately $275.5 million, after deducting the underwriting discount and other offering expenses, which DFT contributed to the Operating Partnership in exchange for OP units.

12. Equity Compensation Plan

In May 2011, our Board of Directors adopted the 2011 Equity Incentive Plan (the “2011 Plan”) following approval from our stockholders. The 2011 Plan is administered by the Compensation Committee of our Board of Directors. The 2011 Plan allows us to provide equity-based compensation to our personnel and directors in the form of stock options, stock appreciation rights, dividend equivalent rights, restricted stock, restricted stock units, performance-based awards, unrestricted stock, long term incentive units ("LTIP units") and other awards.

The 2011 Plan authorizes a maximum aggregate of 6,300,000 share equivalents be reserved for future issuances. In addition, under the 2011 Plan, shares of common stock that are subject to awards of options or stock appreciation rights will be counted against the 2011 Plan share limit as one share for every one share subject to the award. Any shares of stock that are subject to awards other than options or stock appreciation rights shall be counted against the 2011 Plan share limit as 2.36 shares for every one share subject to the award.

As of December 31, 2016, 3,913,287 share equivalents were issued under the 2011 Plan, and the maximum aggregate amount of share equivalents remaining available for future issuance was 2,386,713.

These amounts will be amortized to expense over the respective vesting periods, which are typically three years. Also during the years ended December 31, 2016, 2015 and 2014, 167,419, 138,585 and 125,798 shares of restricted stock vested, respectively, at intrinsic values of $6.2 million, $4.3 million and $3.4 million on their respective vesting dates.

As of December 31, 2016, total unearned compensation on restricted stock was $6.4 million, and the weighted average vesting period was 1.1 years.

Stock Options

Stock option awards are granted with an exercise price equal to the closing market price of DFT’s common stock at the date of grant and vest over specified periods of time as long as the employee remains employed with the Company. All shares to be issued upon option exercises will be newly issued shares and the options have 10-year contractual terms. During the year ended December 31, 2016, no options were granted to employees. The last grant of stock options occurred in 2013, and all stock option grants have fully vested.

Performance Units

Performance unit awards are awarded to certain executive employees and have a three calendar-year performance period with no dividend rights. Performance units are settled in common shares following the performance period as long as the employee remains employed with us on the vesting date following the last day of the applicable performance period. Performance units are valued using a Monte Carlo simulation and are amortized over approximately a three year vesting period from the grant date to the vesting date. The number of common shares settled could range from 0% to 300%. For performance unit award grants prior to 2014, the vesting amount is dependent on DFT’s total stockholder return compared to the MSCI US REIT index over the three calendar-year performance period.

For performance unit grants awarded in 2014 and thereafter, one-half of the recipient's performance unit award is dependent on DFT’s total stockholder return compared to the MSCI US REIT index over the three calendar-year performance period. The other half of the performance unit award is dependent on DFT’s total stockholder return compared to an index of five comparable publicly traded data center companies over the three calendar-year performance period. The following table summarizes the assumptions used to value, and the resulting fair and maximum values of, the performance units granted during the years ended December 31, 2016, 2015 and 2014.

	2016	2015	2014
Number of performance units granted	112,951	48,674	110,441

(1) Represents accelerated vesting of performance units due to departure of certain executives. In connection with the departure of our former CEO in February 2015, 320,676 common shares were issued pursuant to the accelerated vesting of certain of his unvested performance units. $1.9 million was expensed during the first quarter of 2015 related to the accelerated vesting of these performance units.

(2) For the performance units granted in 2012, based on DFT’s total stockholder return compared to the MSCI US REIT index return for the period from January 1, 2012 to January 1, 2015, no common shares were issued upon vesting on March 1, 2015.

(3) For the performance units granted in 2013, 115,437 common shares were issued due to the accelerated vesting of certain unvested performance units, which represented a 300% payout. Based on DFT’s total stockholder return compared to the MSCI US REIT index return for the period from January 1, 2013 to January 1, 2016, 32,985 common shares were issued upon the vesting of these performance units on March 1, 2016, which represented a 300% payout.

(4) For the performance units granted in 2014, 205,240 common shares were issued, which represented a 300% payout, and 2,125 common shares were issued, which represented a 100% payout, due to the accelerated vesting of certain unvested performance units. Based on DFT’s total stockholder return compared to the MSCI US REIT index return for half of the grant and an index of five comparable publicly traded data center companies for the other half of the grant for the period from January 1, 2014 to January 1, 2017, 57,177 common shares will be issued upon their vesting on March 1, 2017, which represents an aggregate payout of 150%.

During the year ended December 31, 2016, no performance units were forfeited. During the year ended December 31, 2015, 4,225 performance units were forfeited with a weighted average fair value of $36.30 per unit. During the year ended December 31, 2014, no performance units were forfeited.

As of December 31, 2016, total unearned compensation on outstanding performance units was $3.7 million.

15. Employee Benefit Plan

We have a tax qualified retirement plan (“401(k) Plan”) that provides employees with an opportunity to save for retirement on a tax advantaged basis. Employees participate in the 401(k) Plan on their first day of employment and are able to defer compensation up to the limits established by the Internal Revenue Service. We match 50% of the employees' contributions up to a maximum match contribution of 4% of the employees' eligible compensation. Our contributions vest immediately. For the years ended December 31, 2016, 2015 and 2014 we contributed $0.6 million, $0.5 million and $0.4 million, respectively, to the 401(k) Plan.

16. Fair Value

Assets and Liabilities Measured at Fair Value

We follow the authoritative guidance issued by the FASB relating to fair value measurements that defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The guidance applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the guidance does not require any new fair value measurements of reported balances. The guidance excludes the accounting for leases, as well as other authoritative guidance that address fair value measurements on lease classification and measurement. The authoritative guidance issued by the FASB emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability.

115

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have 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 level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to 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.

The authoritative guidance issued by the FASB requires disclosure of the fair value of financial instruments. Fair value estimates are subjective in nature and are dependent on a number of important assumptions, including estimates of future cash flows, risks, discount rates, and relevant comparable market information associated with each financial instrument. The use of different market assumptions and estimation methodologies may have a material effect on the reported estimated fair value amounts. Accordingly, the amounts are not necessarily indicative of the amounts we would realize in a current market exchange.

The following methods and assumptions were used in estimating the fair value amounts and disclosures for financial instruments as of December 31, 2016 and 2015:

• Cash and cash equivalents: The carrying amount of cash and cash equivalents reported in the accompanying consolidated balance sheets approximates fair value because of the short maturity of these instruments (i.e., less than 90 days).

• Rents and other receivables, accounts payable and accrued liabilities, and prepaid rents: The carrying amount of these assets and liabilities reported in the accompanying consolidated balance sheets approximates fair value because of the short-term nature of these amounts.

• Debt: As of December 31, 2016, the combined balance of the Unsecured Notes due 2021, Unsecured Notes due 2023, Unsecured Term Loan, Unsecured Credit Facility and ACC3 Term Loan, excluding the effect of deferred financing costs, was $1,260.5 million with a fair value of $1,291.0 million. The Unsecured Notes due 2021 and the Unsecured Notes due 2023 were valued based on Level 2 data which consisted of a quoted price from Bloomberg. The Unsecured Term Loan, the US dollar-denominated borrowings under the Unsecured Credit facility and ACC3 Term Loan were valued based on Level 3 data which consisted of a one-month LIBOR swap rate coterminous with the maturity of each loan plus a spread consistent with current market conditions. The Canadian dollar-denominated borrowings under the Unsecured Credit facility were valued based on Level 3 data which consisted of a one-month Canadian Dollar Offered Rate swap rate coterminous with the maturity of the Unsecured Credit Facility plus a spread consistent with current market conditions.

As of December 31, 2015, the combined balance of the Unsecured Notes due 2021, Unsecured Notes due 2023, Unsecured Term Loan and ACC3 Term Loan, excluding the effect of deferred financing costs, was $1,213.1 million with a fair value of $1,237.2 million. The Unsecured Notes due 2021 and the Unsecured Notes due 2023 were valued based on Level 2 data which consisted of a quoted price from Bloomberg. The ACC3 Loan and the Unsecured Term Loan were valued based on Level 3 data which consisted of a one-month LIBOR swap rate coterminous with the maturity of each loan plus a spread consistent with current market conditions.

ITEM 9A. CONTROLS AND PROCEDURES

Controls and Procedures with Respect to DFT

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of DFT's management, including DFT's principal executive officer and principal financial officer, DFT conducted an evaluation of the effectiveness of the design and operation of DFT's disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this report (the “Evaluation Date”). Based on this evaluation, DFT's principal executive officer and principal financial officer concluded as of the Evaluation Date that DFT's disclosure controls and procedures were effective such that the information relating to DFT, including DFT's consolidated subsidiaries, required to be disclosed in DFT's Securities and Exchange Commission (“SEC”) reports (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to DFT's management, including DFT's principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

Under the supervision and with the participation of DFT's management, including DFT's principal executive officer and principal financial officer, DFT conducted an evaluation of any changes in DFT's internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during DFT's most recently completed fiscal quarter. Based on that evaluation, DFT's principal executive officer and principal financial officer concluded that there has not been any change in DFT's internal control over financial reporting during that quarter that has materially affected, or is reasonably likely to materially affect, DFT's internal control over financial reporting.

Management's Report on Internal Control over Financial Reporting

DFT's management is responsible for establishing and maintaining adequate internal control over financial reporting. DFT'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 U.S. generally accepted accounting principles. DFT's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of its assets;

128

(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of its management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of its 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.

DFT's management assessed the effectiveness of its internal control over financial reporting as of December 31, 2016, utilizing the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013 Framework). Based on the assessment by its management, DFT determined that its internal control over financial reporting was effective as of December 31, 2016. The effectiveness of DFT's internal control over financial reporting as of December 31, 2016 has been audited by Ernst & Young LLP, DFT's independent registered public accounting firm, as stated in their report which appears on page 71 of this Annual Report on Form 10-K.

Controls and Procedures with respect to the Operating Partnership

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of DFT's management, including DFT's principal executive officer and principal financial officer, DFT conducted an evaluation of the effectiveness of the design and operation of the Operating Partnership's disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this report (the “Evaluation Date”). Based on this evaluation, DFT's principal executive officer and principal financial officer concluded as of the Evaluation Date that the Operating Partnership's disclosure controls and procedures were effective such that the information relating to the Operating Partnership, including the Operating Partnership's consolidated subsidiaries, required to be disclosed in the Operating Partnership's SEC reports (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to DFT's management, including DFT's principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
