EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2015 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 March 31, 2015, DFT owned 80.9% 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 quarterly reports on Form 10-Q 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 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 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 and retained earnings. 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 March 31, 2015 is 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.

DuPont Fabros Technology, Inc. (“DFT”), through its controlling interest in DuPont Fabros Technology, L.P. (the “Operating Partnership” or “OP” and collectively with DFT and their operating subsidiaries, the “Company”), is a fully integrated, self-administered and self-managed company that owns, acquires, develops and operates wholesale data centers. DFT is a real estate investment trust, or REIT, for federal income tax purposes and is the sole general partner of the Operating Partnership, and as of March 31, 2015, owned 80.9% of the common economic interest in the Operating Partnership, of which 1.0% is held as general partnership units. 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 March 31, 2015, we held a fee simple interest in the following properties:

• 11 operating data centers – ACC2, ACC3, ACC4, ACC5, ACC6, ACC7 Phase I, VA3, VA4, CH1, NJ1 Phase I and SC1 Phases I and IIA;

• three data centers currently under development – SC1 Phase IIB, CH2 Phase I and ACC7 Phase II;

• data center projects available for future development – ACC7 Phases III-IV, CH2 Phases II-III and NJ1 Phase II; and

• land that may be used to develop additional data centers – ACC8 and SC2.

SC1 Phase IIB was placed into service in May 2015.

2. Significant Accounting Policies

Basis of Presentation

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2015 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 quarterly reports on Form 10-Q 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 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 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 and retained earnings. 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-

12

operating partnership” in DFT’s consolidated financial statements. The only difference between the assets and liabilities of DFT and the Operating Partnership as of March 31, 2015 is 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 unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. All significant intercompany accounts and transactions have been eliminated in the accompanying consolidated financial statements. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the full year. These consolidated financial statements should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations contained elsewhere in this Form 10-Q and the audited financial statements and accompanying notes for the year ended December 31, 2014 contained in our Annual Report on Form 10-K, which contains a complete listing of our significant accounting policies.

We have one reportable segment consisting of investments in data centers located in the United States. 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

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 $23.9 million and $22.2 million for the three months ended March 31, 2015 and 2014, respectively. Included in these amounts is amortization expense related to tenant origination costs, which was $0.7 million and $0.8 million for the three months ended March 31, 2015 and 2014, respectively. Repairs and maintenance costs are expensed as incurred.

We record impairment losses on long-lived assets used in operations or in development when events or changes in circumstances indicate that the assets might be impaired, and the estimated undiscounted cash flows to be generated by those assets are less than the carrying amounts. If circumstances indicating impairment of a long-lived asset are present, we would determine the fair value of that asset, and an impairment loss would be recognized in an amount equal to the excess of the carrying amount of the impaired asset over its fair value. We assess the recoverability of the carrying value of our assets on a property-by-property basis. No impairment losses were recorded during the three months ended March 31, 2015 and 2014.

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. In May 2014, we amended our unsecured revolving credit facility ("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 our unsecured

term loan agreement ("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. Balances, net of accumulated amortization, at March 31, 2015 and December 31, 2014 were as follows (in thousands):

13

	March 31, 2015			December 31, 2014
Financing costs	$	24,110		$	24,110
Accumulated amortization	(7,693		)	(6,820		)
Financing costs, net	$	16,417		$	17,290

Leasing costs, which are either external fees and costs incurred in the successful negotiations of leases, internal costs expended in the successful negotiations of leases or 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 related leases on a straight-line basis. If an applicable lease terminates prior to the expiration of its initial term, the carrying amount of the costs are written off to amortization expense. Leasing costs incurred for the three months ended March 31, 2015 and 2014 were as follows (in thousands):

	Three months ended March 31,
	2015		2014
Leasing costs incurred for new leases	$	373	$	52
Leasing costs incurred for renewals	1,101		—
Total leasing costs incurred	$	1,474	$	52

Amortization of deferred leasing costs totaled $1.1 million and $1.0 million for the three months ended March 31, 2015 and 2014, respectively. Balances, net of accumulated amortization, at March 31, 2015 and December 31, 2014 were as follows (in thousands):

	March 31, 2015			December 31, 2014
Leasing costs	$	53,832		$	52,358
Accumulated amortization	(32,220		)	(31,153		)
Leasing costs, net	$	21,612		$	21,205

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 March 31, 2015 and December 31, 2014, the fuel inventory was $4.4 million and $4.3 million, respectively, and is included in prepaid expenses and other assets in the accompanying consolidated balance sheets.

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 leases, 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. Lease inducements, which include free rent or cash payments to customers, are amortized as a reduction of rental income over the non-cancellable lease term. Straight-line rents receivable are included in deferred rent 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 lease intangibles associated with that lease will be written off to rental revenue. Balances, net of accumulated amortization, at March 31, 2015 and December 31, 2014 were as follows (in thousands):

14

	March 31, 2015			December 31, 2014
Lease contracts above market value	$	23,100		$	23,100
Accumulated amortization	(15,321		)	(15,046		)
Lease contracts above market value, net	$	7,779		$	8,054
Lease contracts below market value	$	39,375		$	39,375
Accumulated amortization	(33,206		)	(32,338		)
Lease contracts below market value, net	$	6,169		$	7,037

Our policy is to record a reserve 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 March 31, 2015 and December 31, 2014, we applied interest received to the note principal balance and had reserves against rents and other receivables of $5.1 million and $4.9 million, respectively. 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 March 31, 2015 and December 31, 2014, we had reserves against deferred rent of $3.7 million.

The reserves described above were established for one customer that restructured its lease obligations with us during 2013. Under this restructuring, this customer's outstanding accounts receivable and deferred rent receivable related to the space that was returned to us were converted into a note receivable, the terms of which require the payment of principal and interest through December 31, 2016. Principal payments on the note are calculated on a ten-year amortization schedule with a final principal payment of the remaining note balance due on December 31, 2016. Additionally, under this restructuring, this customer deferred two-thirds of its base rent payments due for its lease at our NJ1 facility through July 2014, which were added to the note. In February 2015, this customer filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code. To date, we have applied the interest portion of all note payments received, totaling $1.2 million, to the note principal balance on our consolidated balance sheet. The note balance as of March 31, 2015 and December 31, 2014 was $6.5 million and $6.6 million, respectively, which is recorded within rents and other receivables, net in our accompanying consolidated balance sheets. The note receivable balance, net of reserves and interest applied to the principal, as of March 31, 2015 and December 31, 2014 was $1.4 million and $1.7 million, respectively.

Due to the uncertainty surrounding this customer's ability to pay its contractual rent obligations, we have also reserved $3.7 million of this customer's deferred rent receivable balance of $8.5 million as of March 31, 2015.

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. Most of our 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 projects such as the purchase and installation of circuits, racks, breakers and other customer requested items. 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.

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 (“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 “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.

15

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 6). 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 three months ended March 31, 2015 (dollars in thousands):

	OP Units
	Number		Amount

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.

16

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 award stock-based compensation to employees and members of our Board of Directors in the form of common stock. For each 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.

Recently Issued Accounting Pronouncements

In March 2015, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which will change the presentation of debt issuance costs on our consolidated balance sheet. The new guidance requires that deferred financing costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the debt liability rather than as an asset. We will be required to apply ASU 2015-03 in the first quarter of 2016 and apply the guidance retrospectively to all prior periods presented.

In May 2014, the Financial Accounting Standards Board issued a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP. 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 will be required to apply the new standard in the first quarter of 2017 and are assessing whether the new standard will have a material effect on our financial position or results of operations.

Outstanding Indebtedness

ACC3 Term Loan

We have a $115 million term loan facility (the “ACC3 Term Loan”) that is secured by our ACC3 data center facility and an assignment of the lease agreement between us and the customer of ACC3. 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 loan as of March 31, 2015.

Unsecured Term Loan

We have an unsecured term loan facility (the "Unsecured Term Loan"), which has a total commitment and amount outstanding of $250 million. The Unsecured Term Loan matures on July 21, 2019, and we may prepay the facility at any time, in whole or in part, without penalty or premium.

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.

18

		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.

The Unsecured Term Loan is unconditionally guaranteed jointly and severally, on a senior unsecured basis by DFT and the direct and indirect subsidiaries of DFT that guaranty the obligations of the Unsecured Credit Facility (as defined below).

The Unsecured Term Loan requires that we comply with various covenants that are substantially the same as those applicable under the Unsecured Credit Facility, including with respect to restrictions on liens, incurring indebtedness, making investments, effecting mergers and/or asset sales, and certain restrictions on dividend payments. In addition, the Unsecured Term Loan imposes financial maintenance covenants substantially the same as those under the Unsecured Credit Facility relating to, among other things, the following matters:

• unsecured debt not exceeding 60% of the value of unencumbered assets;

• net operating income generated from unencumbered properties divided by the amount of unsecured debt being not less than 12.5%;

• total indebtedness not exceeding 60% of gross asset value;

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

• tangible net worth being not less than $1.3 billion plus 80% of the sum of (i) net equity offering proceeds after March 21, 2012 and (ii) the value of equity interests issued in connection with a contribution of assets to the Operating Partnership or its subsidiaries after March 21, 2012. 

The Unsecured Term Loan 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 under the loan to be immediately due and payable.

We were in compliance with all of the covenants under the loan as of March 31, 2015.

On September 24, 2013, the Operating Partnership completed the sale of $600 million of 5.875% unsecured notes due 2021 (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,

19

VA3, VA4, CH1, NJ1 and SC1 data centers and the SC2 land (collectively, the “Subsidiary Guarantors”), but excluding the subsidiaries that own the ACC3 and ACC7 data center facilities, the CH2 data center under development, the ACC8 land, our taxable REIT subsidiary, DF Technical Services, LLC and our property management subsidiary, DF Property Management LLC.

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.

At any time prior to September 15, 2016, the Operating Partnership may redeem the Unsecured Notes due 2021, in whole or in part, at a price equal to the sum of (i) 100% of the principal amount of the Unsecured Notes due 2021 to be redeemed, plus (ii) a make-whole premium and accrued and unpaid interest. The Unsecured Notes due 2021 may be redeemed at the Operating Partnership's option, in whole or in part, at any time, on and after September 15, 2016 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 or prohibiting the ability of 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 March 31, 2015.

Unsecured Credit Facility

We have an unsecured revolving credit facility ("Unsecured Credit Facility") with a total commitment of $560 million. The Unsecured Credit Facility matures on May 13, 2018 and includes a one-year extension option, subject to the payment of an extension fee equal to 15 basis points on the total commitment in effect on such initial maturity date and certain other customary conditions. At our option, we may increase the total commitment under the facility to $800 million, if one or more lenders commit to being a lender for the additional amount and certain other customary conditions are met. We may also prepay the facility at any time, in whole or in part, without penalty or premium.

We may elect to have borrowings under the facility 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.

20

		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 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 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	0.875	%	0.00	%
Level 2	Greater than or equal to BBB+ by S&P or Baa1 by Moody’s	0.925	%	0.00	%
Level 3	Greater than or equal to BBB by S&P or Baa2 by Moody’s	1.05	%	0.05	%
Level 4	Greater than or equal to BBB- by S&P or Baa3 by Moody’s	1.30	%	0.30	%
Level 5	Less than BBB- by S&P or Baa3 by Moody’s	1.70	%	0.70	%

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

The facility is 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 above.

The amount available for borrowings under the 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 facility may be used for letters of credit.

As of March 31, 2015, a letter of credit totaling less than $0.1 million was outstanding under the facility. As of March 31, 2015, $150.0 million of borrowings were outstanding under this facility. As of May 7, 2015, $180.0 million of borrowings were outstanding under this facility.

The facility 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;

• net operating income generated from unencumbered properties divided by the amount of unsecured debt being not less than 12.5%;

• total indebtedness not exceeding 60% of gross asset value;

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

• tangible net worth being not less than $1.3 billion plus 80% of the sum of (i) net equity offering proceeds after March 21, 2012 and (ii) the value of equity interests issued in connection with a contribution of assets to the Operating Partnership or its subsidiaries.

The facility 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 facility as of March 31, 2015.

5. 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.

Contracts related to the development of the SC1 Phase IIB, CH2 Phase I and ACC7 Phase II data centers were in place as of March 31, 2015. These contracts are cost plus in nature whereby the contract sum is the aggregate of the actual work performed and equipment purchased 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 March 31, 2015, the SC1 Phase IIB control estimate was $55.2 million, of which $48.8 million has been incurred. An additional $1.6 million has been committed under this contract as of March 31, 2015. As of March 31, 2015, the CH2 Phase I control estimate was $165.1 million, of which $130.3 million has been incurred. An additional $21.0 million has been committed under this contract as of March 31, 2015. As of March 31, 2015, the ACC7 Phase II control estimate was $39.1 million, of which $1.8 million has been incurred. An additional $12.6 million has been committed under this contract as of March 31, 2015.

In February 2015, we entered into two purchase agreements under which we will acquire two parcels of undeveloped land in Ashburn, Virginia, from entities controlled by Lammot J. du Pont, our Chairman of the Board, and Hossein Fateh, our Vice Chairman of the Board.

One agreement relates to the purchase of a 34.8 acre site that is adjacent to the Ashburn Corporate Center, where our ACC2, ACC3, ACC4, ACC5, ACC6 and ACC7 data center facilities are located, for a total purchase price of $15.5 million. The sole managers of the entity that owns this site are a limited liability company owned solely by Mr. du Pont, which also owns approximately 7% of the seller, and a limited liability company owned solely by Mr. Fateh, which also owns approximately 1% of the seller.

The other agreement relates to the purchase of an 8.7 acre site that is part of the Ashburn Corporate Center and adjacent to our ACC4 and ACC7 data center facilities for a total purchase price of $4.6 million. Mssrs. du Pont and Fateh are the sole managers of the limited liability company that manages the entity that owns this site. Mr. du Pont directly and indirectly owns approximately 23% of the seller, and Mr. Fateh 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 owns 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 by an independent appraisal firm.

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 DFT’s Chairman and Vice Chairman of the Board. 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

22

reimbursement payment. The amount of initial built-in gain that can be recognized as of January 1, 2015 without triggering the tax protection provisions is approximately 80% of the initial built in gain of $667 million (unaudited), or $534 million (unaudited). This percentage increases each year by 10%, accumulating to 100% in 2017. As of March 31, 2015, none of the tax protection provisions had been triggered and no liability has been recorded on our consolidated balance sheet. If, as of January 1, 2015, the tax protection provisions were triggered, we could be liable for protection on the taxes related to up to approximately $12 million (unaudited) of 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 $97 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.

6. 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 March 31, 2015 and December 31, 2014 was $503.9 million and $513.1 million, respectively, based on the closing share price of DFT’s common stock of $32.68 and $33.24, 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 three months ended March 31, 2015, OP unitholders redeemed a total of 18,000 OP units in exchange for an equal number of shares of common stock. See Note 2.

7. Preferred Stock

Series A Preferred Stock

In October 2010, DFT issued 7,400,000 shares of 7.875% Series A Cumulative Redeemable Perpetual Preferred Stock (“Series A Preferred Stock”) for $185.0 million in an underwritten public offering. The liquidation preference on the Series A Preferred Stock is $25 per share and dividends are scheduled quarterly. For each share of Series A Preferred Stock issued by DFT, the Operating Partnership issued a preferred unit equivalent to DFT with the same terms.

In 2015, DFT declared and paid the following cash dividends on its Series A Preferred Stock, of which the OP paid equivalent distributions on its preferred units:

• $0.4921875 per share payable to stockholders of record as of April 2, 2015. This dividend was paid on April 15, 2015.

Series B Preferred Stock

In March 2011 and January 2012, DFT issued an aggregate of 6,650,000 shares of 7.625% Series B Cumulative Redeemable Perpetual Preferred Stock (“Series B Preferred Stock”) for $166.3 million in underwritten public offerings. The liquidation preference on the Series B Preferred Stock is $25 per share and dividends are scheduled quarterly. For each share of Series B Preferred Stock issued by DFT, the Operating Partnership issued a preferred unit equivalent to DFT with the same terms.

In 2015, DFT declared and paid the following cash dividends on its Series B Preferred Stock, of which the OP paid equivalent distributions on its preferred units:

• $0.4765625 per share payable to stockholders of record as of April 2, 2015. This dividend was paid on April 15, 2015.

8. Stockholders’ Equity of DFT and Partners’ Capital of the OP

In 2015, DFT declared and paid the following cash dividend per share on its common stock, of which the OP paid an equivalent distribution on OP units:

• $0.42 per share payable to stockholders of record as of April 2, 2015. This dividend was paid on April 15, 2015.

23

In December 2014, the Board of Directors approved a common stock repurchase program to acquire up to $120.0 million of DFT's common stock in 2015. This program was announced on February 5, 2015, and will expire on December 31, 2015. During the three months ended March 31, 2015, DFT repurchased 1,002,610 shares of its common stock, and $88.1 million is still available for repurchase under the program. All repurchased shares were retired immediately, and the OP retired an equivalent number of units.

In connection with the departure of our former chief executive officer, Hossein Fateh, in February 2015, DFT issued the following shares of common stock during the three months ended March 31, 2015, of which the OP issued an equivalent number of units to the REIT:

• an award of 55,742 shares of fully vested common stock with a fair value of $1.8 million on the grant date, which was expensed during the three months ended March 31, 2015,

• 346 shares of fully vested common stock as consideration for Mr. Fateh's continuing service as Vice Chairman of the Board of Directors with a fair value of less than $0.1 million on the grant date, and

• 320,676 shares of fully vested common stock in connection with the accelerated vesting of certain unvested performance units held by Mr. Fateh. $1.9 million was expensed during the three months ended March 31, 2015 related to the accelerated vesting of these performance units.

Furthermore, $0.3 million was expensed during the three months ended March 31, 2015 in connection with the accelerated vesting of certain unvested stock options held by Mr. Fateh. Mr. Fateh is also entitled to receive a cash severance payment of $1.3 million which was expensed during the three months ended March 31, 2015 and will be paid six months following his separation date.

9. 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, shares that were awarded under our 2007 Equity Compensation Plan (the “2007 Plan”) that subsequently become available due to forfeitures of such awards are available for issuance under the 2011 Plan.

The 2011 Plan provides that awards can no longer be made under the 2007 Plan. Furthermore, 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 March 31, 2015, 3,198,419 share equivalents were issued under the 2011 Plan, and the maximum aggregate amount of share equivalents remaining available for future issuance was 3,101,581.

Restricted Stock

Restricted stock awards vest over specified periods of time as long as the employee remains employed with the Company. The following table sets forth the number of unvested shares of restricted stock and the weighted average fair value of these shares at the date of grant:

	Shares of Restricted Stock		Weighted Average Fair Value at Date of Grant

Unvested balance at March 31, 2015	352,559		$	27.76

During the three months ended March 31, 2015, we issued 153,655 shares of restricted stock, which had an aggregate value of $5.0 million on the grant date. This amount will be amortized to expense over the respective vesting periods, which are

24

typically three years. Also during the three months ended March 31, 2015, 124,197 shares of restricted stock vested at a value of $3.9 million on the respective vesting dates.

As of March 31, 2015, total unearned compensation on restricted stock was $9.0 million, and the weighted average vesting period was 1.7 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 three months ended March 31, 2015, no options were granted to employees.

A summary of our stock option activity under the applicable equity incentive plan for the three months ended March 31, 2015 is presented in the tables below.

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 will be settled in common shares following the performance period as long as the employee remains employed with us on the vesting date, which is the March 1st date following the last day of the applicable performance period. Performance units are valued using a Monte Carlo simulation and are amortized over the 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 2015, 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 three months ended March 31, 2015.

	Assumption
Number of performance units granted	48,674
Expected volatility	24		%
Expected annual dividend	5.18		%
Risk-free rate	1.06		%
Performance unit fair value at date of grant	$	38.34
Total grant fair value at date of grant	$1.9 million
Maximum value of grant on vesting date based on closing price of DFT's stock at the date of grant	$4.7 million

During three months ended March 31, 2015, no performance units were forfeited. As of March 31, 2015, total unearned compensation on outstanding performance units was $2.8 million.

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 their vesting on

March 31, 2015.

12. Fair Value

Assets and Liabilities Measured at Fair Value

The authoritative guidance issued by the Financial Accounting Standards Board 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 March 31, 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: The combined balance of our Unsecured Notes due 2021, Unsecured Term Loan, Unsecured Credit Facility and ACC3 Term Loan was $1,115.0 million with a fair value of $1,137.5 million based on Level 2 data. The Unsecured Notes due 2021 were valued based on Level 2 data which consisted of a quoted price for the Unsecured Notes due 2021 from Bloomberg. Because our ACC3 Term Loan, Unsecured Credit Facility and Unsecured Term Loan were refinanced in 2014, we believe that their carrying values approximate each of their fair values as of March 31, 2015. Each of these loans bear interest at LIBOR plus a spread that is consistent with current market conditions.

13. Supplemental Consolidating Financial Data for Subsidiary Guarantors of the Unsecured Notes

On September 24, 2013, the Operating Partnership issued the Unsecured Notes due 2021 (See Note 4). The Unsecured Notes due 2021 are unconditionally guaranteed, jointly and severally on a senior unsecured basis by DFT and certain of our subsidiaries, including the subsidiaries that own the ACC2, ACC4, ACC5, ACC6, VA3, VA4, CH1, NJ1 and SC1 data centers and the SC2 land (collectively, the "Subsidiary Guarantors"), but excluding the subsidiaries that own the ACC3 and ACC7 data center facilities, the CH2 data center under development, the ACC8 land and the TRS collectively, the "Subsidiary Non-Guarantors"). The following consolidating financial information sets forth the financial position as of March 31, 2015 and December 31, 2014 and the results of operations and cash flows for the three months ended March 31, 2015 and 2014 of the Operating Partnership, Subsidiary Guarantors and the Subsidiary Non-Guarantors.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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.

For a detailed discussion of certain of the risks and uncertainties that could cause our future results to differ materially from any forward-looking statements, see Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014. You should also review the risks, uncertainties and other factors discussed in this Quarterly Report on Form 10-Q 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.

Overview

DuPont Fabros Technology, Inc. (“DFT”) was formed on March 2, 2007, is a real estate investment trust, or REIT, and is headquartered in Washington, D.C. DFT is a fully integrated, self-administered and self-managed company that owns, acquires, develops and operates wholesale data centers. DFT is the sole general partner of, and, as of March 31, 2015, owned 80.9% 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. DFT’s common stock trades on the New York Stock Exchange, or NYSE, under the symbol “DFT.” DFT’s Series A and Series B preferred stock also trade on the NYSE under the symbols “DFTPrA” and “DFTPrB”, respectively.

As of March 31, 2015, we owned and operated 11 data centers, eight of which are located in Northern Virginia, one in suburban Chicago, Illinois, one in Piscataway, New Jersey and one in Santa Clara, California. As discussed below, we also own certain properties for future development and parcels of land that we intend to develop in the future, into wholesale data centers. With this portfolio of properties, we believe that we are well positioned as a fully integrated wholesale data center provider, capable of developing, leasing, operating and managing our growing portfolio.

(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 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 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 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).

(1) 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. The respective amounts listed for each of the “Land Held for Development” sites are estimates.

(2) CRSF is that portion of gross building area where customers locate their computer servers. The respective amounts listed for each of the “Land Held for Development” sites are estimates.

(3) 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 MW or kW (1 MW is equal to 1,000 kW). The respective amounts listed for each of the “Land Held for Development” sites are estimates.

(4) Current development projects include land, capitalization for construction and development and capitalized interest and operating carrying costs, as applicable, upon completion. Future development projects/phases include land, shell and underground work through Phase I opening only.

(5) Amount capitalized as of March 31, 2015. Future development projects/phases include land, shell and underground work through Phase I opening only.

(6) SC1 Phase IIB was placed into service on May 1, 2015 and was 100% leased on a CRSF and critical load basis.

(7) As of May 7, 2015, CH2 Phase I was 20% pre-leased on a CRSF and critical load basis.

(8) Amounts listed are updated estimates. We are currently evaluating the best use for this land. Options include a stand-alone data center, an additional phase of SC1 or a powered base shell.

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 the three months ended March 31, 2015, we executed two leases representing a total of 2.20 MW of critical load and 9,039 CRSF of space with a weighted average lease term of 6.8 years. These leases included the following:

41

• One lease at ACC7 Phase I comprising 2.00 MW of critical load and 8,179 CRSF.

• One lease at ACC5 comprising 0.20 MW of critical load and 860 CRSF.

During the three months ended March 31, 2015, we also renewed two leases at ACC4 for a weighted average of 7.0 years totaling 2.28 MW and 10,800 CRSF.

Each of our leases includes pass-through provisions under which customers are required to pay for their pro rata share of most of the property level operating expenses, including real estate taxes and insurance – commonly referred to as a triple net lease. Also, customers pay for certain of our operating properties' capital expenditures over their estimated life. In addition, under our triple-net lease structure, customers pay directly for the power they use to run their servers and other computer equipment and power that is used to cool their spaces. We intend to continue to structure future wholesale leases as triple net leases. Most of our leases also provide us with a property management fee based on a percentage of base rent collected and property-level operating expenses (excluding charges for power used by customers to run their servers and cool their spaces). Also, most of our leases provide for annual rent increases, generally at a rate of 2%-3% or by an amount tied to increases to the consumer price index.

We lease power and space on a long-term basis, and our weighted average remaining lease term for commenced leases was approximately 5.8 years as of April 1, 2015. Approximately 13% of our leases – in terms of annualized base rent – are scheduled to expire prior to the end of 2017. Our ability to generate rental income over time will depend on our ability to retain customers when their leases expire or re-lease at attractive rates the power and space available from leases that expire and are not renewed or are otherwise terminated. Also, we receive expense reimbursement from customers only on power and space that is leased. Consequently, vacancies result in portions of our operating expenses being unreimbursed, which in turn negatively impacts our revenues and net income.

As of April 1, 2015, we had 37 customers with 106 lease expiration dates. Only two of these leases have terms that expire in 2015. As discussed further below, the lease for 10.4 MW of space at ACC2 expires in September 2015, and the customer has notified us that it will not be renewing its lease. In addition, a lease for 1.14 MW of space at ACC5 expires in June 2015.

Available Data Center Inventory and Current Development Projects

As of May 7, 2015, our operating portfolio was 94% leased and commenced as measured by CRSF and by critical load. The opportunity for revenue growth in the near term primarily depends on our ability to lease the 6% remaining vacant space in our operating portfolio. The opportunity for revenue growth beyond the near term will depend on our ability to lease space at the data center facilities currently under development.

We have two operating data center facilities with a significant amount of vacant space, as follows:

• ACC7 Phase I - 6.4 MW of critical load available for lease; and

• NJ1 Phase I - 7.5 MW of critical load available for lease. We believe that when we fully lease the CRSF at NJ1, there will be 3-4 MW of critical load unleased. We intend to seek to divert the remaining excess power for use in NJ1 Phase II, if and when that phase is developed, but there can be no assurance that we will be able to utilize this critical load power in NJ1 Phase II.

As of May 7, 2015, the two data center facilities currently under development are as follows:

• CH2 Phase I - 7.1 MW of available critical load of which 20% has been pre-leased, with completion expected in the third quarter of 2015; and

•ACC7 Phase II - 8.9 MW of available critical load, with completion expected in the fourth quarter of 2015.

As of May 7, 2015, SC1 Phase IIB has been placed into service 100% leased on a critical load basis and on a CRSF basis.

Our four largest customers comprised 61% of our annualized base rent as of March 31, 2015. None of the leases of our three largest customers have early termination rights. The fourth largest customer has early termination rights in certain of its leases, and we have reflected these leases in the Lease Expiration Table above at the early termination dates. We expect these customers to evaluate their lease expirations in the year before expiration is scheduled to occur, taking into account, among other factors, their anticipated need for server capacity and economic factors. If we cannot renew these leases at similar rates or attract replacement customers on similar terms in a timely manner, our rental income could be materially adversely impacted in future periods.

Market Conditions

Changes in the conditions of any of the markets in which our operating properties are located 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 technology industry.

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. In determining 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.

In each of our stabilized properties, we have been able to lease space and power at rates that provide a favorable return on our investment in these facilities. There has been pricing pressure in some of the markets in which we compete, including lower rates and increased concessions. Although we believe that there are indications that rental rates have stabilized, it is unclear if pricing pressure will return, which would adversely impact the rental rates, and, in turn, the rates of return of our investment, that we can obtain as we pursue leasing available space and power. In particular, given that the weighted average remaining lease term for commenced leases was approximately 5.8 years as of April 1, 2015, it is difficult to predict the market conditions that will exist when our lease portfolio expires. If the current market conditions were to continue through the terms of these leases, the rental rates of a number of leases in our portfolio could be impacted adversely if the existing customers were to either vacate the space or renegotiate the rental rate as a condition to their renewal of the lease. If we are unable to lease vacant space with rents equal to or above historic rates, the returns on our investments we have achieved to date at the properties recently placed into service would be impacted negatively.

For the two lease renewals executed during the three months ended March 31, 2015 totaling 2.28 MW and 10,800 CRSF, described above, GAAP base rent is 9.1% higher than GAAP base rent prior to the renewal, in the aggregate, on a straight line basis. Cash base rent for these two renewals will decline 1.6%, in the aggregate, at the time the renewal rates take effect compared to cash base rents in place at the end of the original lease terms.

One of our four largest customers, Yahoo!, leases all 10.4 MW of the critical load available in our ACC2 data center facility through a lease that expires in September 2015 and represents 4% of our operating property portfolio's annualized base rent. Yahoo! has notified us that it will not renew its ACC2 lease and that it is able to move out of the space with 30 days' notice. This additional inventory of available data center space could have a negative impact on demand for space that we have available in Northern Virginia and the rental rates for such space. We believe that we will be able to lease this space to new customers if and when the current customer vacates the space because we have been successful in re-leasing vacated space at our VA3 data center facility. The space at ACC2, however, provides for more power per square foot of computing space than at VA3, which may limit the potential customers that can use the ACC2 space efficiently. We forecast an approximate 20% decline in cash base rents upon re-leasing the vacant space. We, however, cannot ensure that we will be able to attract replacement customers on similar terms in a timely manner for this space and, if we are unable to do so, our rental income could be materially adversely impacted in future periods.

The inability of a customer to meet its rent obligations would impact our revenues and cash flows negatively. Adverse economic and other market conditions could impact the ability of any of our customers to fulfill their lease obligations. Specifically, in January and February 2015, Net Data Centers, the customer that restructured three of its leases with us in the first quarter of 2013, halted its base rent payments and paid only its monthly operating expenses, direct electric charges and management fees for these two months. In February 2015, Net Data Centers filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code. Since this filing under Chapter 11, we have received payment for all rent obligations for March, April and May totaling $3.8 million in the aggregate.

As of March 31, 2015, we have reserved a total of $5.1 million of the note receivable due from this customer, which represents 79% of the outstanding balance of the note, which totaled $6.5 million as of March 31, 2015. The terms of this note require the payment of principal and interest through maturity on December 31, 2016. Principal payments on the note are calculated on a ten-year amortization schedule, with a final principal payment of the remaining note balance due at maturity. We have also reserved $3.7 million, or 43%, of Net Data Center's aggregate deferred rent receivable balance totaling $8.5 million as of March 31, 2015. In summary, we had a total of $6.2 million of unreserved receivables from Net Data Centers as of March 31, 2015. As of May 7, 2015, Net Data Centers has not announced its intentions regarding its leases with the Company as part of its bankruptcy reorganization. It is possible that, as part of its bankruptcy reorganization, one or more of the Net Data

43

Centers leases with the Company could be terminated or modified, which could have an adverse effect on our business and results of operations. Net Data Centers represents 3.5% of our operating property portfolio's annualized base rent and has the following leases with us:

Property	MW leased	CRSF Leased	Lease Expiration Year
ACC4	2.28	10,800	2020
ACC5	0.40	1,930	2027
NJ1 Phase I	2.28	11,000	2023
VA3	1.30	15,122	2023
Total	6.26	38,852

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 “a la carte” services. Such services include the installation of circuits, racks, breakers and other customer requested items. The TRS will generally charge customers for these services on a cost-plus basis. Because the degree of utilization of the TRS for these services 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 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. Because demand for its services is unpredictable, we anticipate that the TRS may retain a significant amount of its cash to fund future operations, and therefore we do not expect to receive distributions from the TRS on a regular basis.

Results of Operations

This Quarterly Report on Form 10-Q contains stand-alone unaudited 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 March 31, 2015, owned 80.9% of the common economic interest in the Operating Partnership, of which approximately 1.0% 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.

Three Months Ended March 31, 2015 Compared to Three Months Ended March 31, 2014

Operating Revenue. Operating revenue for the three months ended March 31, 2015 was $107.3 million. This includes base rent of $71.6 million, which includes our management fee, tenant recoveries of $33.3 million and other revenue of $2.4 million, including revenue from a la carte projects for our customers performed by the TRS. This compares to revenue of $102.1 million for the three months ended March 31, 2014. The increase of $5.2 million, or 5.1%, was primarily due to increased revenue from placing ACC7 Phase I and SC1 Phase IIA into service and from new leases commencing at ACC5, NJ1 Phase I, and VA3, partially offset by a $2.6 million decrease in revenue due to base rent revenue not being recognized during the first quarter of 2015 for one of our customers currently in bankruptcy.

Operating Expenses. Operating expenses for the three months ended March 31, 2015 were $72.1 million, compared to $61.9 million for the three months ended March 31, 2014. The increase of $10.2 million, or 16.5%, was primarily due to a $6.4 million increase in other expenses primarily due to a charge of $5.6 million in the first quarter of 2015 for severance compensation and the acceleration of unvested equity awards associated with the departure of our former chief executive officer. The remaining increase in operating expenses was due to $1.8 million of increased depreciation and amortization from the opening of ACC7 Phase I and SC1 Phase IIA, increased operating costs from placing ACC7 Phase I and SC1 Phase IIA into service and an increase in costs resulting from an increase in a la carte projects for our customers performed by our TRS.

Interest Expense. Interest expense, including amortization of deferred financing costs, for the three months ended March 31, 2015 was $8.9 million compared to interest expense of $8.6 million for the three months ended March 31, 2014. Total interest incurred for the three months ended March 31, 2015 was $12.0 million, of which $3.1 million was capitalized, as compared to $11.7 million for the corresponding period in 2014, of which $3.1 million was capitalized. The increase in total interest was primarily due to increased draws on our line of credit.

Net Income Attributable to Redeemable Noncontrolling interests – Operating Partnership (DFT only). Net income attributable to redeemable noncontrolling interests – operating partnership for the three months ended March 31, 2015 was $3.7 million compared to $4.8 million for the three months ended March 31, 2014. The decrease of $1.1 million was primarily due to the Operating Partnership receiving its allocation of lower net income and a decrease in ownership of redeemable

44

noncontrolling interests – operating partnership due to OP unitholders redeeming 0.3 million OP units in exchange for an equal number of shares of DFT’s common stock during the period from January 1, 2014 through March 31, 2015.

Net Income Attributable to Common Shares. Net income attributable to common shares for the three months ended March 31, 2015 was $15.8 million compared to $20.0 million for the three months ended March 31, 2014. The decrease of $4.2 million was due to expenses associated with the departure of our former chief executive officer and the bankruptcy of one of our customers, described above.

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 three months ended March 31, 2015 was a $4.2 million bank account at DFT that is not part of the Operating Partnership.

Three Months Ended March 31, 2015 Compared to Three Months Ended March 31, 2014

Net cash provided by operating activities increased by $4.6 million, or 10.3%, to $49.1 million for the three months ended March 31, 2015, as compared to $44.5 million for the corresponding period in 2014. The increase was primarily due to higher cash rents from tenants and an increase in accounts payable and accrued liabilities.

Net cash used in investing activities decreased by $22.6 million to $61.2 million for the three months ended March 31, 2015 compared to $83.8 million for the corresponding period in 2014. The majority of cash used in investing activities in each period was expenditures for projects under development. During the three months ended March 31, 2015, cash used for development was primarily for the construction of CH2 Phase I. During the three months ended March 31, 2014, the majority of cash used was for two developments, SC1 Phase IIA and the ACC7 Phase I, and accordingly, development costs paid in the first quarter of 2014 were $22.6 million higher than the first quarter of 2015.

Net cash provided by financing activities was $9.6 million for the three months ended March 31, 2015 compared to $72.3 million in the corresponding period in 2014. Net cash provided by financing activities for the three months ended March 31, 2015 consisted of $90 million in proceeds from our Unsecured Credit Facility; partially offset by $41.0 million paid for dividends and distributions, $31.9 million in repurchases of our common stock and $7.5 million of cash used in connection with the payment of withholding taxes for employees upon the vesting of restricted common stock or grant of unrestricted common stock. Cash provided by financing activities for the three months ended March 31, 2014 consisted of $96.0 million of proceeds from the final draw of the Unsecured Term Loan and $3.5 million of proceeds received from stock option exercises, net of cash used in connection with the payment of withholding taxes for employees, partially offset by $27.0 million paid for dividends and distributions.

Capital Resources

The development and construction of wholesale data centers is very capital intensive. Such development not only requires us to make substantial capital investments, but also increases our operating expenses, which impacts our cash flows from operations negatively 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, DFT is required to distribute at least 90% of “REIT taxable income,” excluding any net capital gain, to its stockholders annually.

In 2015, we expect to meet our liquidity needs from cash provided by operating activities and from external sources. 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. For future developments, we expect to have availability under our Unsecured Credit Facility and would fund development costs, at least temporarily, by drawing funds from this facility until we obtained permanent capital financing. We expect to obtain permanent capital through unsecured and secured borrowings, construction financings and the issuance of additional preferred and/or common equity, when market conditions permit. 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 our Unsecured Notes due 2021 and Unsecured Credit Facility (each defined herein), 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.

In December 2014, the Board of Directors approved a common stock repurchase program to acquire up to $120 million of DFT's shares of common stock in 2015. This program was announced on February 5, 2015. Depending on our analysis of market prices, economic conditions and other opportunities for the investment of available capital, including data center development, we may repurchase our common stock pursuant to the program. Between February 18, 2015 and March 31, 2015, we repurchased a total of 1,002,610 shares for a total purchase price of $31.9 million. These purchases constituted 1.5% of the balance of common stock outstanding as of December 31, 2014. Shares were purchased at an average price of $31.80 per share and were retired immediately. We may purchase an additional $88.1 million of our common stock pursuant to the stock repurchase program.

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 indenture that governs our Unsecured Notes due 2021 limits DFT’s ability to pay dividends, but allows DFT to pay the minimum necessary to meet its REIT income distribution requirements.

Outstanding Indebtedness

ACC3 Term Loan

We have a $115 million term loan facility (the “ACC3 Term Loan”) that is secured by our ACC3 data center facility and an assignment of the lease agreement between us and the customer of ACC3. 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 loan as of March 31, 2015.

Unsecured Term Loan

We have an unsecured term loan facility (the "Unsecured Term Loan"), which has a total commitment and amount outstanding of $250 million. The Unsecured Term Loan matures on July 21, 2019, and we may prepay the facility at any time, in whole or in part, without penalty or premium.

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.

47

		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.

The Unsecured Term Loan is unconditionally guaranteed jointly and severally, on a senior unsecured basis by DFT and the direct and indirect subsidiaries of DFT that guaranty the obligations of the Unsecured Credit Facility (as defined below).

The Unsecured Term Loan requires that we comply with various covenants that are substantially the same as those applicable under the Unsecured Credit Facility, including with respect to restrictions on liens, incurring indebtedness, making investments, effecting mergers and/or asset sales, and certain restrictions on dividend payments. In addition, the Unsecured Term Loan imposes financial maintenance covenants substantially the same as those under the Unsecured Credit Facility relating to, among other things, the following matters:

• unsecured debt not exceeding 60% of the value of unencumbered assets;

• net operating income generated from unencumbered properties divided by the amount of unsecured debt being not less than 12.5%;

• total indebtedness not exceeding 60% of gross asset value;

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

• tangible net worth being not less than $1.3 billion plus 80% of the sum of (i) net equity offering proceeds after March 21, 2012 and (ii) the value of equity interests issued in connection with a contribution of assets to the Operating Partnership or its subsidiaries after March 21, 2012. 

The Unsecured Term Loan 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 under the loan to be immediately due and payable.

We were in compliance with all of the covenants under the loan as of March 31, 2015.

Unsecured Notes due 2021

On September 24, 2013, the Operating Partnership completed the sale of $600 million of 5.875% unsecured notes due 2021 (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,

48

VA3, VA4, CH1, NJ1 and SC1 data centers and the SC2 land (collectively, the “Subsidiary Guarantors”), but excluding the subsidiaries that own the ACC3 and ACC7 data center facilities, the CH2 data center under development, the ACC8 land, our taxable REIT subsidiary, DF Technical Services, LLC and our property management subsidiary, DF Property Management LLC.

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.

At any time prior to September 15, 2016, the Operating Partnership may redeem the Unsecured Notes due 2021, in whole or in part, at a price equal to the sum of (i) 100% of the principal amount of the Unsecured Notes due 2021 to be redeemed, plus (ii) a make-whole premium and accrued and unpaid interest. The Unsecured Notes due 2021 may be redeemed at the Operating Partnership's option, in whole or in part, at any time, on and after September 15, 2016 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 or prohibiting the ability of 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 March 31, 2015.

Unsecured Credit Facility

We have an unsecured revolving credit facility ("Unsecured Credit Facility") with a total commitment of $560 million. The Unsecured Credit Facility matures on May 13, 2018 and includes a one-year extension option, subject to the payment of an extension fee equal to 15 basis points on the total commitment in effect on such initial maturity date and certain other customary conditions. At our option, we may increase the total commitment under the facility to $800 million, if one or more lenders commit to being a lender for the additional amount and certain other customary conditions are met. We may also prepay the facility at any time, in whole or in part, without penalty or premium.

We may elect to have borrowings under the facility 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.

49

		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 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 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	0.875	%	0.00	%
Level 2	Greater than or equal to BBB+ by S&P or Baa1 by Moody’s	0.925	%	0.00	%
Level 3	Greater than or equal to BBB by S&P or Baa2 by Moody’s	1.05	%	0.05	%
Level 4	Greater than or equal to BBB- by S&P or Baa3 by Moody’s	1.30	%	0.30	%
Level 5	Less than BBB- by S&P or Baa3 by Moody’s	1.70	%	0.70	%

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

The facility is 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 above.

The amount available for borrowings under the 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 facility may be used for letters of credit.

As of March 31, 2015, a letter of credit totaling less than $0.1 million was outstanding under the facility. As of March 31, 2015, $150.0 million of borrowings were outstanding under this facility. As of May 7, 2015, $180.0 million of borrowings were outstanding under this facility.

The facility 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;

• net operating income generated from unencumbered properties divided by the amount of unsecured debt being not less than 12.5%;

• total indebtedness not exceeding 60% of gross asset value;

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

• tangible net worth being not less than $1.3 billion plus 80% of the sum of (i) net equity offering proceeds after March 21, 2012 and (ii) the value of equity interests issued in connection with a contribution of assets to the Operating Partnership or its subsidiaries.

The facility 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 facility as of March 31, 2015.

Off-Balance Sheet Arrangements

As of March 31, 2015, the Company did not have any off-balance sheet arrangements.

Funds From Operations

	Three months ended March 31,
(in thousands)	2015			2014
Net income (loss)	$	26,333		$	31,644
Depreciation and amortization	25,027			23,269
Less: Non real estate depreciation and amortization	(144		)	(172		)
FFO (1)	$	51,216		$	54,741

(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

51

assets, plus specified non-cash items, such as real estate asset depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.

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.

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.

Critical Accounting Policies

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 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. Our critical accounting policies and estimates have not changed materially from the discussion of our significant accounting policies found in Management’s Discussion and Analysis and Results of Operations in our Form 10-K.

Recently Issued Accounting Pronouncements

In March 2015, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which will change the presentation of debt issuance costs on our consolidated balance sheet. The new guidance requires that deferred financing costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the debt liability rather than as an asset. We will be required to apply ASU 2015-03 in the first quarter of 2016 and apply the guidance retrospectively to all prior periods presented.

In May 2014, the Financial Accounting Standards Board issued a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP. 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 will be required to apply the new standard in the first quarter of 2017 and are assessing whether the new standard will have a material effect on our financial position or results of operations.

ITEM 3. 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 Unsecured Credit Facility all currently bear interest at a rate equal to LIBOR plus an applicable margin. If interest rates were to increase by 1%, the increase in interest expense on our variable rate debt outstanding as of March 31, 2015 would decrease future net income and cash flows by $5.2 million annually less the impact of capitalization of interest incurred on net income. Because one month LIBOR was approximately 0.17% at March 31, 2015, a decrease of 0.17% would increase future net income and cash flows by $0.9 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 March 31, 2015, 54% 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.

FIRST AMENDMENT TO SEVERANCE AGREEMENT

THIS FIRST AMENDMENT TO EMPLOYMENT AGREEMENT (this “First Amendment”) is dated as of December 1, 2011, by and between DuPont Fabros Technology, Inc., a Maryland corporation (the “Company”), DF Property Management LLC, a Delaware limited liability company (the “LLC”), and Scott A. Davis (the “Executive”).

A.The Company and the Executive are parties to a Severance Agreement (the “Original Agreement”), dated as of March 31, 2009.

B.The parties desire to amend the Original Agreement to (i) modify certain provisions related to the death or disability of Executive, and (ii) add the LLC as a party to the agreement so that references to Executive’s employment by and services for the Company shall also include Executive’s services for the LLC.

Accordingly, the parties hereto agree as follows:

1.    Section 2.5 is hereby amended to add subsection (d) as follows:

(d)    Notwithstanding anything to the contrary in this Section 2.5, in the event of (1) Executive’s death while employed pursuant to this Agreement, or (2) Executive’s employment is terminated based on Executive’s Disability, all stock options, common stock subject to forfeiture, restricted stock units and other equity awards held by Executive at the time of his/her termination of employment that would have become vested and exercisable or free from repurchase restrictions, as applicable, during the twelve (12) month period commencing on the date of termination if Executive had remained employed during such period shall become vested and exercisable or free from such repurchase restrictions as of the Release Date.

2.    Section 3.1 of the Original Agreement is hereby amended and restated as follows:

3.1Position. Subject to the terms set forth herein, the LLC (or the Company, either directly or through one of its subsidiaries) agrees to employ Executive, initially in the position of Executive Vice President of Operations, and Executive hereby accepts such employment. During the term of Executive’s employment with the LLC (or the Company, or one of its subsidiaries), Executive will devote Executive’s best efforts and substantially all of Executive’s business time and attention to the business of the LLC, the Company and its subsidiaries. References in this Agreement to Executive’s employment with the LLC also refer to Executive’s employment with the Company or one of its subsidiaries, if applicable. In no event shall the prior sentence prohibit Executive from (i) performing charitable activities; (ii) delivering lectures at educational institutions or professional or corporate associations, or (iii) any other activity approved in advance by the Company’s Chief Executive Officer (“CEO”), so long as such activities do not contravene the prior sentence. Without the prior approval of the Board, Executive shall not serve in any executive capacity or as a member of the governing board of any private or public for-profit company.

3.    Unless specifically modified herein, all other terms and conditions of the Original Agreement shall remain in effect.

IN WITNESS WHEREOF, the parties hereto have signed their names as of the day and year first above written.

SECOND AMENDMENT TO SEVERANCE AGREEMENT

THIS SECOND AMENDMENT TO SEVERANCE AGREEMENT (this “Second Amendment”) is dated December 12, 2012, and is between DuPont Fabros Technology, Inc., a Maryland corporation (the “Company”), DF Property Management LLC, a Delaware limited liability company (the “LLC”), and Scott A. Davis (the “Executive”).

A.    The Company and the Executive are parties to a Severance Agreement, dated March 31, 2009, as amended by the First Amendment to Severance Agreement, dated December 1, 2011 (together, the “Agreement”).

B.    The parties desire to amend the Agreement to modify certain provisions of the Agreement to ensure that they comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended.

Accordingly, the parties agree as follows:

1.Section 2.9 of the Agreement is amended by adding the following sentence to the end of such Section:

It is further the intention of the parties that all of the payments under Sections 2.3, 2.4, 2.5 and 2.10 of this Agreement satisfy, to the greatest extent possible, the exemptions from the application of Section 409A(a) of the Code provided under Treasury Regulation Sections 1.409A-1(b)(4) and 1.409A-1(b)(9), and this Agreement will be construed to the greatest extent possible as consistent with those provisions. If not so exempt, this Agreement (and any definitions under this Agreement) will be construed in a manner that complies with Section 409A, and incorporates by reference all required definitions and payment terms.

2.Section 2.12 of the Agreement is amended by adding the following sentence to the end of such Section:

Notwithstanding the foregoing, in the event the period during which Executive may review and revoke the Release begins in one calendar year and ends in the following calendar year, the Release Date with respect to any amount payable under Section 2.3, 2.4, 2.5 or 2.10 shall be in the second calendar year, regardless of whether Executive executes the Release and the Release becomes irrevocable during the first calendar year.

3.Section 2.13 of the Agreement is amended and restated as follows:

2.13 General Severance Policies. The benefits provided to Executive pursuant to Sections 2.3, 2.4, 2.5 and 2.10 are in lieu of, and not in addition to, any benefits to which Executive may otherwise be entitled under any Company severance plan, policy or program; provided, however, that if the dollar value of the benefits to which Executive would otherwise be entitled under any Company severance plan, policy or program are more favorable in the aggregate to Executive than the dollar value of the benefits provided under this Agreement, he/she will be entitled to receive the additional benefits provided under such other plan, policy or program in accordance with the terms of the plan, policy or program to the extent the dollar value of such benefits exceeds the dollar value of the benefits provided under this Agreement. Notwithstanding the foregoing, in no

event shall Executive’s entitlement to additional benefits under any other Company plan, policy or program replace or be a substitute for, or change the time or form of payment of, the benefits provided under this Agreement.

4.Unless specifically modified herein, all other terms and conditions of the Agreement shall remain in effect.

IN WITNESS WHEREOF, the parties have signed this Agreement below.

Exhibit 31.1

CERTIFICATION PURSUANT TO SECTION 302 OF

THE SARBANES-OXLEY ACT OF 2002

1. I have reviewed this Quarterly Report on Form 10-Q of DuPont Fabros Technology, Inc.;

2. Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;

Basis of Presentation

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2015 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 quarterly reports on Form 10-Q 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 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 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 and retained earnings. 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 March 31, 2015 is 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 unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. All significant intercompany accounts and transactions have been eliminated in the accompanying consolidated financial statements. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the full year. These consolidated financial statements should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations contained elsewhere in this Form 10-Q and the audited financial statements and accompanying notes for the year ended December 31, 2014 contained in our Annual Report on Form 10-K, which contains a complete listing of our significant accounting policies.

We have one reportable segment consisting of investments in data centers located in the United States. 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

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 $23.9 million and $22.2 million for the three months ended March 31, 2015 and 2014, respectively. Included in these amounts is amortization expense related to tenant origination costs, which was $0.7 million and $0.8 million for the three months ended March 31, 2015 and 2014, respectively. Repairs and maintenance costs are expensed as incurred.

We record impairment losses on long-lived assets used in operations or in development when events or changes in circumstances indicate that the assets might be impaired, and the estimated undiscounted cash flows to be generated by those assets are less than the carrying amounts. If circumstances indicating impairment of a long-lived asset are present, we would determine the fair value of that asset, and an impairment loss would be recognized in an amount equal to the excess of the carrying amount of the impaired asset over its fair value. We assess the recoverability of the carrying value of our assets on a property-by-property basis. No impairment losses were recorded during the three months ended March 31, 2015 and 2014.

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. In May 2014, we amended our unsecured revolving credit facility ("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 our unsecured

term loan agreement ("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. Balances, net of accumulated amortization, at March 31, 2015 and December 31, 2014 were as follows (in thousands):

	March 31, 2015			December 31, 2014
Financing costs	$	24,110		$	24,110
Accumulated amortization	(7,693		)	(6,820		)
Financing costs, net	$	16,417		$	17,290

Leasing costs, which are either external fees and costs incurred in the successful negotiations of leases, internal costs expended in the successful negotiations of leases or 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 related leases on a straight-line basis. If an applicable lease terminates prior to the expiration of its initial term, the carrying amount of the costs are written off to amortization expense. Leasing costs incurred for the three months ended March 31, 2015 and 2014 were as follows (in thousands):

	Three months ended March 31,
	2015		2014
Leasing costs incurred for new leases	$	373	$	52
Leasing costs incurred for renewals	1,101		—
Total leasing costs incurred	$	1,474	$	52

Amortization of deferred leasing costs totaled $1.1 million and $1.0 million for the three months ended March 31, 2015 and 2014, respectively. Balances, net of accumulated amortization, at March 31, 2015 and December 31, 2014 were as follows (in thousands):

	March 31, 2015			December 31, 2014
Leasing costs	$	53,832		$	52,358
Accumulated amortization	(32,220		)	(31,153		)
Leasing costs, net	$	21,612		$	21,205

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 March 31, 2015 and December 31, 2014, the fuel inventory was $4.4 million and $4.3 million, respectively, and is included in prepaid expenses and other assets in the accompanying consolidated balance sheets.

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 leases, 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. Lease inducements, which include free rent or cash payments to customers, are amortized as a reduction of rental income over the non-cancellable lease term. Straight-line rents receivable are included in deferred rent 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 lease intangibles associated with that lease will be written off to rental revenue. Balances, net of accumulated amortization, at March 31, 2015 and December 31, 2014 were as follows (in thousands):

	March 31, 2015			December 31, 2014
Lease contracts above market value	$	23,100		$	23,100
Accumulated amortization	(15,321		)	(15,046		)
Lease contracts above market value, net	$	7,779		$	8,054
Lease contracts below market value	$	39,375		$	39,375
Accumulated amortization	(33,206		)	(32,338		)
Lease contracts below market value, net	$	6,169		$	7,037

Our policy is to record a reserve 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 March 31, 2015 and December 31, 2014, we applied interest received to the note principal balance and had reserves against rents and other receivables of $5.1 million and $4.9 million, respectively. 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 March 31, 2015 and December 31, 2014, we had reserves against deferred rent of $3.7 million.

The reserves described above were established for one customer that restructured its lease obligations with us during 2013. Under this restructuring, this customer's outstanding accounts receivable and deferred rent receivable related to the space that was returned to us were converted into a note receivable, the terms of which require the payment of principal and interest through December 31, 2016. Principal payments on the note are calculated on a ten-year amortization schedule with a final principal payment of the remaining note balance due on December 31, 2016. Additionally, under this restructuring, this customer deferred two-thirds of its base rent payments due for its lease at our NJ1 facility through July 2014, which were added to the note. In February 2015, this customer filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code. To date, we have applied the interest portion of all note payments received, totaling $1.2 million, to the note principal balance on our consolidated balance sheet. The note balance as of March 31, 2015 and December 31, 2014 was $6.5 million and $6.6 million, respectively, which is recorded within rents and other receivables, net in our accompanying consolidated balance sheets. The note receivable balance, net of reserves and interest applied to the principal, as of March 31, 2015 and December 31, 2014 was $1.4 million and $1.7 million, respectively.

Due to the uncertainty surrounding this customer's ability to pay its contractual rent obligations, we have also reserved $3.7 million of this customer's deferred rent receivable balance of $8.5 million as of March 31, 2015.

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. Most of our 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 projects such as the purchase and installation of circuits, racks, breakers and other customer requested items. 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.

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 (“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 “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 6). 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 three months ended March 31, 2015 (dollars in thousands):

	OP Units
	Number		Amount
Balance at December 31, 2014	15,437,237		$	513,134

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 award stock-based compensation to employees and members of our Board of Directors in the form of common stock. For each 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.

Recently Issued Accounting Pronouncements

In March 2015, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which will change the presentation of debt issuance costs on our consolidated balance sheet. The new guidance requires that deferred financing costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the debt liability rather than as an asset. We will be required to apply ASU 2015-03 in the first quarter of 2016 and apply the guidance retrospectively to all prior periods presented.

In May 2014, the Financial Accounting Standards Board issued a comprehensive new revenue recognition standard that will supersede nearly all existing revenue recognition guidance under GAAP. 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 will be required to apply the new standard in the first quarter of 2017 and are assessing whether the new standard will have a material effect on our financial position or results of operations.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies Disclosure [Text Block]

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.

Contracts related to the development of the SC1 Phase IIB, CH2 Phase I and ACC7 Phase II data centers were in place as of March 31, 2015. These contracts are cost plus in nature whereby the contract sum is the aggregate of the actual work performed and equipment purchased 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 March 31, 2015, the SC1 Phase IIB control estimate was $55.2 million, of which $48.8 million has been incurred. An additional $1.6 million has been committed under this contract as of March 31, 2015. As of March 31, 2015, the CH2 Phase I control estimate was $165.1 million, of which $130.3 million has been incurred. An additional $21.0 million has been committed under this contract as of March 31, 2015. As of March 31, 2015, the ACC7 Phase II control estimate was $39.1 million, of which $1.8 million has been incurred. An additional $12.6 million has been committed under this contract as of March 31, 2015.

In February 2015, we entered into two purchase agreements under which we will acquire two parcels of undeveloped land in Ashburn, Virginia, from entities controlled by Lammot J. du Pont, our Chairman of the Board, and Hossein Fateh, our Vice Chairman of the Board.

One agreement relates to the purchase of a 34.8 acre site that is adjacent to the Ashburn Corporate Center, where our ACC2, ACC3, ACC4, ACC5, ACC6 and ACC7 data center facilities are located, for a total purchase price of $15.5 million. The sole managers of the entity that owns this site are a limited liability company owned solely by Mr. du Pont, which also owns approximately 7% of the seller, and a limited liability company owned solely by Mr. Fateh, which also owns approximately 1% of the seller.

The other agreement relates to the purchase of an 8.7 acre site that is part of the Ashburn Corporate Center and adjacent to our ACC4 and ACC7 data center facilities for a total purchase price of $4.6 million. Mssrs. du Pont and Fateh are the sole managers of the limited liability company that manages the entity that owns this site. Mr. du Pont directly and indirectly owns approximately 23% of the seller, and Mr. Fateh 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 owns 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 by an independent appraisal firm.

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 DFT’s Chairman and Vice Chairman of the Board. 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, 2015 without triggering the tax protection provisions is approximately 80% of the initial built in gain of $667 million (unaudited), or $534 million (unaudited). This percentage increases each year by 10%, accumulating to 100% in 2017. As of March 31, 2015, none of the tax protection provisions had been triggered and no liability has been recorded on our consolidated balance sheet. If, as of January 1, 2015, the tax protection provisions were triggered, we could be liable for protection on the taxes related to up to approximately $12 million (unaudited) of 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 $97 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.

Outstanding Indebtedness

ACC3 Term Loan

We have a $115 million term loan facility (the “ACC3 Term Loan”) that is secured by our ACC3 data center facility and an assignment of the lease agreement between us and the customer of ACC3. 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 loan as of March 31, 2015.

We have an unsecured term loan facility (the "Unsecured Term Loan"), which has a total commitment and amount outstanding of $250 million. The Unsecured Term Loan matures on July 21, 2019, and we may prepay the facility at any time, in whole or in part, without penalty or premium.

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.

The Unsecured Term Loan is unconditionally guaranteed jointly and severally, on a senior unsecured basis by DFT and the direct and indirect subsidiaries of DFT that guaranty the obligations of the Unsecured Credit Facility (as defined below).

The Unsecured Term Loan requires that we comply with various covenants that are substantially the same as those applicable under the Unsecured Credit Facility, including with respect to restrictions on liens, incurring indebtedness, making investments, effecting mergers and/or asset sales, and certain restrictions on dividend payments. In addition, the Unsecured Term Loan imposes financial maintenance covenants substantially the same as those under the Unsecured Credit Facility relating to, among other things, the following matters:

• unsecured debt not exceeding 60% of the value of unencumbered assets;

• net operating income generated from unencumbered properties divided by the amount of unsecured debt being not less than 12.5%;

• total indebtedness not exceeding 60% of gross asset value;

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

• tangible net worth being not less than $1.3 billion plus 80% of the sum of (i) net equity offering proceeds after March 21, 2012 and (ii) the value of equity interests issued in connection with a contribution of assets to the Operating Partnership or its subsidiaries after March 21, 2012. 

The Unsecured Term Loan 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 under the loan to be immediately due and payable.

We were in compliance with all of the covenants under the loan as of March 31, 2015.

Unsecured Notes due 2021

On September 24, 2013, the Operating Partnership completed the sale of $600 million of 5.875% unsecured notes due 2021 (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, NJ1 and SC1 data centers and the SC2 land (collectively, the “Subsidiary Guarantors”), but excluding the subsidiaries that own the ACC3 and ACC7 data center facilities, the CH2 data center under development, the ACC8 land, our taxable REIT subsidiary, DF Technical Services, LLC and our property management subsidiary, DF Property Management LLC.

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.

At any time prior to September 15, 2016, the Operating Partnership may redeem the Unsecured Notes due 2021, in whole or in part, at a price equal to the sum of (i) 100% of the principal amount of the Unsecured Notes due 2021 to be redeemed, plus (ii) a make-whole premium and accrued and unpaid interest. The Unsecured Notes due 2021 may be redeemed at the Operating Partnership's option, in whole or in part, at any time, on and after September 15, 2016 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 or prohibiting the ability of 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 March 31, 2015.

Unsecured Credit Facility

We have an unsecured revolving credit facility ("Unsecured Credit Facility") with a total commitment of $560 million. The Unsecured Credit Facility matures on May 13, 2018 and includes a one-year extension option, subject to the payment of an extension fee equal to 15 basis points on the total commitment in effect on such initial maturity date and certain other customary conditions. At our option, we may increase the total commitment under the facility to $800 million, if one or more lenders commit to being a lender for the additional amount and certain other customary conditions are met. We may also prepay the facility at any time, in whole or in part, without penalty or premium.

We may elect to have borrowings under the facility 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%	1.55	%	0.55	%
Level 2	Greater than 35% but less than or equal to 40%	1.65	%	0.65	%

Level 5	Greater than 52.5%	2.15	%	1.15	%

The applicable margin is currently set at pricing level 1. The terms of the 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 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	0.875	%	0.00	%
Level 2	Greater than or equal to BBB+ by S&P or Baa1 by Moody’s	0.925	%	0.00	%
Level 3	Greater than or equal to BBB by S&P or Baa2 by Moody’s	1.05	%	0.05	%
Level 4	Greater than or equal to BBB- by S&P or Baa3 by Moody’s	1.30	%	0.30	%
Level 5	Less than BBB- by S&P or Baa3 by Moody’s	1.70	%	0.70	%

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

The facility is 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 above.

The amount available for borrowings under the 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 facility may be used for letters of credit.

As of March 31, 2015, a letter of credit totaling less than $0.1 million was outstanding under the facility. As of March 31, 2015, $150.0 million of borrowings were outstanding under this facility. As of May 7, 2015, $180.0 million of borrowings were outstanding under this facility.

The facility 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;

• net operating income generated from unencumbered properties divided by the amount of unsecured debt being not less than 12.5%;

• total indebtedness not exceeding 60% of gross asset value;

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

• tangible net worth being not less than $1.3 billion plus 80% of the sum of (i) net equity offering proceeds after March 21, 2012 and (ii) the value of equity interests issued in connection with a contribution of assets to the Operating Partnership or its subsidiaries.

The facility 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 facility as of March 31, 2015.

12. Fair Value

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Fair Value

Assets and Liabilities Measured at Fair Value

The authoritative guidance issued by the Financial Accounting Standards Board 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 March 31, 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: The combined balance of our Unsecured Notes due 2021, Unsecured Term Loan, Unsecured Credit Facility and ACC3 Term Loan was $1,115.0 million with a fair value of $1,137.5 million based on Level 2 data. The Unsecured Notes due 2021 were valued based on Level 2 data which consisted of a quoted price for the Unsecured Notes due 2021 from Bloomberg. Because our ACC3 Term Loan, Unsecured Credit Facility and Unsecured Term Loan were refinanced in 2014, we believe that their carrying values approximate each of their fair values as of March 31, 2015. Each of these loans bear interest at LIBOR plus a spread that is consistent with current market conditions.

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 March 31, 2015 and December 31, 2014 was $503.9 million and $513.1 million, respectively, based on the closing share price of DFT’s common stock of $32.68 and $33.24, 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 three months ended March 31, 2015, OP unitholders redeemed a total of 18,000 OP units in exchange for an equal number of shares of common stock. See Note 2.

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, shares that were awarded under our 2007 Equity Compensation Plan (the “2007 Plan”) that subsequently become available due to forfeitures of such awards are available for issuance under the 2011 Plan.

The 2011 Plan provides that awards can no longer be made under the 2007 Plan. Furthermore, 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 March 31, 2015, 3,198,419 share equivalents were issued under the 2011 Plan, and the maximum aggregate amount of share equivalents remaining available for future issuance was 3,101,581.

Restricted Stock

Restricted stock awards vest over specified periods of time as long as the employee remains employed with the Company. The following table sets forth the number of unvested shares of restricted stock and the weighted average fair value of these shares at the date of grant:

	Shares of Restricted Stock		Weighted Average Fair Value at Date of Grant
Unvested balance at December 31, 2014	323,989		$	24.10
Granted	153,655		$	32.26
Vested	(124,197	)	$	23.78
Forfeited	(888	)	$	24.61
Unvested balance at March 31, 2015	352,559		$	27.76

During the three months ended March 31, 2015, we issued 153,655 shares of restricted stock, which had an aggregate value of $5.0 million on the grant date. This amount will be amortized to expense over the respective vesting periods, which are typically three years. Also during the three months ended March 31, 2015, 124,197 shares of restricted stock vested at a value of $3.9 million on the respective vesting dates.

As of March 31, 2015, total unearned compensation on restricted stock was $9.0 million, and the weighted average vesting period was 1.7 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 three months ended March 31, 2015, no options were granted to employees.

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 will be settled in common shares following the performance period as long as the employee remains employed with us on the vesting date, which is the March 1st date following the last day of the applicable performance period. Performance units are valued using a Monte Carlo simulation and are amortized over the 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 2015, 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 three months ended March 31, 2015.

	Assumption
Number of performance units granted	48,674
Expected volatility	24		%
Expected annual dividend	5.18		%
Risk-free rate	1.06		%
Performance unit fair value at date of grant	$	38.34
Total grant fair value at date of grant	$1.9 million
Maximum value of grant on vesting date based on closing price of DFT's stock at the date of grant	$4.7 million

During three months ended March 31, 2015, no performance units were forfeited. As of March 31, 2015, total unearned compensation on outstanding performance units was $2.8 million.

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 their vesting on

March 31, 2015.

Accounting Policies [Abstract]

Basis of Presentation [Text Block]

Basis of Presentation

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2015 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 quarterly reports on Form 10-Q 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 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 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 and retained earnings. 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 March 31, 2015 is 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 unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. All significant intercompany accounts and transactions have been eliminated in the accompanying consolidated financial statements. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the full year. These consolidated financial statements should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations contained elsewhere in this Form 10-Q and the audited financial statements and accompanying notes for the year ended December 31, 2014 contained in our Annual Report on Form 10-K, which contains a complete listing of our significant accounting policies.

We have one reportable segment consisting of investments in data centers located in the United States. 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 [Policy Text Block]

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 [Policy Text Block]

Property

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 $23.9 million and $22.2 million for the three months ended March 31, 2015 and 2014, respectively. Included in these amounts is amortization expense related to tenant origination costs, which was $0.7 million and $0.8 million for the three months ended March 31, 2015 and 2014, respectively. Repairs and maintenance costs are expensed as incurred.

We record impairment losses on long-lived assets used in operations or in development when events or changes in circumstances indicate that the assets might be impaired, and the estimated undiscounted cash flows to be generated by those assets are less than the carrying amounts. If circumstances indicating impairment of a long-lived asset are present, we would determine the fair value of that asset, and an impairment loss would be recognized in an amount equal to the excess of the carrying amount of the impaired asset over its fair value. We assess the recoverability of the carrying value of our assets on a property-by-property basis. No impairment losses were recorded during the three months ended March 31, 2015 and 2014.

Deferred Costs [Policy Text Block]

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. In May 2014, we amended our unsecured revolving credit facility ("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 our unsecured

term loan agreement ("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. Balances, net of accumulated amortization, at March 31, 2015 and December 31, 2014 were as follows (in thousands):

	March 31, 2015			December 31, 2014
Financing costs	$	24,110		$	24,110
Accumulated amortization	(7,693		)	(6,820		)
Financing costs, net	$	16,417		$	17,290

Leasing costs, which are either external fees and costs incurred in the successful negotiations of leases, internal costs expended in the successful negotiations of leases or 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 related leases on a straight-line basis. If an applicable lease terminates prior to the expiration of its initial term, the carrying amount of the costs are written off to amortization expense. Leasing costs incurred for the three months ended March 31, 2015 and 2014 were as follows (in thousands):

	Three months ended March 31,
	2015		2014
Leasing costs incurred for new leases	$	373	$	52
Leasing costs incurred for renewals	1,101		—
Total leasing costs incurred	$	1,474	$	52

Amortization of deferred leasing costs totaled $1.1 million and $1.0 million for the three months ended March 31, 2015 and 2014, respectively. Balances, net of accumulated amortization, at March 31, 2015 and December 31, 2014 were as follows (in thousands):

	March 31, 2015			December 31, 2014
Leasing costs	$	53,832		$	52,358
Accumulated amortization	(32,220		)	(31,153		)
Leasing costs, net	$	21,612		$	21,205

Inventory [Policy Text Block]

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 March 31, 2015 and December 31, 2014, the fuel inventory was $4.4 million and $4.3 million, respectively, and is included in prepaid expenses and other assets in the accompanying consolidated balance sheets.

Rental Income [Policy Text Block]

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 leases, 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. Lease inducements, which include free rent or cash payments to customers, are amortized as a reduction of rental income over the non-cancellable lease term. Straight-line rents receivable are included in deferred rent 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 lease intangibles associated with that lease will be written off to rental revenue. Balances, net of accumulated amortization, at March 31, 2015 and December 31, 2014 were as follows (in thousands):

	March 31, 2015			December 31, 2014
Lease contracts above market value	$	23,100		$	23,100
Accumulated amortization	(15,321		)	(15,046		)
Lease contracts above market value, net	$	7,779		$	8,054
Lease contracts below market value	$	39,375		$	39,375
Accumulated amortization	(33,206		)	(32,338		)
Lease contracts below market value, net	$	6,169		$	7,037

Our policy is to record a reserve 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 March 31, 2015 and December 31, 2014, we applied interest received to the note principal balance and had reserves against rents and other receivables of $5.1 million and $4.9 million, respectively. 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 March 31, 2015 and December 31, 2014, we had reserves against deferred rent of $3.7 million.

The reserves described above were established for one customer that restructured its lease obligations with us during 2013. Under this restructuring, this customer's outstanding accounts receivable and deferred rent receivable related to the space that was returned to us were converted into a note receivable, the terms of which require the payment of principal and interest through December 31, 2016. Principal payments on the note are calculated on a ten-year amortization schedule with a final principal payment of the remaining note balance due on December 31, 2016. Additionally, under this restructuring, this customer deferred two-thirds of its base rent payments due for its lease at our NJ1 facility through July 2014, which were added to the note. In February 2015, this customer filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code. To date, we have applied the interest portion of all note payments received, totaling $1.2 million, to the note principal balance on our consolidated balance sheet. The note balance as of March 31, 2015 and December 31, 2014 was $6.5 million and $6.6 million, respectively, which is recorded within rents and other receivables, net in our accompanying consolidated balance sheets. The note receivable balance, net of reserves and interest applied to the principal, as of March 31, 2015 and December 31, 2014 was $1.4 million and $1.7 million, respectively.

Due to the uncertainty surrounding this customer's ability to pay its contractual rent obligations, we have also reserved $3.7 million of this customer's deferred rent receivable balance of $8.5 million as of March 31, 2015.

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. Most of our 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 [Policy Text Block]

Other Revenue

Other revenue primarily consists of services provided to customers on a non-recurring basis. This includes projects such as the purchase and installation of circuits, racks, breakers and other customer requested items. 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.

Redeemable Noncontrolling Interests—Operating Partnership / Redeemable Partnership Units [Policy Text Block]

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 (“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 “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 6). 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 three months ended March 31, 2015 (dollars in thousands):

	OP Units

Earnings Per Share of the REIT [Policy Text Block]

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 [Policy Text Block]

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

Stock-based Compensation [Policy Text Block]

Stock-based Compensation

We award stock-based compensation to employees and members of our Board of Directors in the form of common stock. For each 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.
