EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the quarter ended September 30, 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 September 30, 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 September 30, 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2015

(unaudited)

1. Description of Business

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 September 30, 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 September 30, 2015, we held a fee simple interest in the following properties:

• 12 operating data centers – ACC2, ACC3, ACC4, ACC5, ACC6, ACC7 Phase I, VA3, VA4, CH1, CH2 Phase I, NJ1 Phase I and SC1;

• three data centers under development – ACC7 Phase II, ACC7 Phase III and CH2 Phase II;

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

• land that may be used to develop additional data centers – ACC8, CH3, and SC2.

In October 2015, we commenced development of CH2 Phase III.

2. Significant Accounting Policies

Basis of Presentation

This report combines the quarterly reports on Form 10-Q for the quarter ended September 30, 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 September 30, 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 and nine months ended September 30, 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 $25.3 million and $23.7 million for the three months ended September 30, 2015 and 2014, respectively, and $73.4 million and $68.4 million for the nine months ended September 30, 2015 and 2014, respectively. Included in these amounts is amortization expense related to tenant origination costs, which was $0.5 million and $0.8 million for the three months ended September 30, 2015 and 2014, respectively, and $1.7 million and $2.4 million for the nine months ended September 30, 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 nine months ended September 30, 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 September 30, 2015 and December 31, 2014 were as follows (in thousands):

13

	September 30, 2015			December 31, 2014
Financing costs	$	28,721		$	24,110
Accumulated amortization	(9,525		)	(6,820		)
Financing costs, net	$	19,196		$	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. In June 2015, we wrote off $0.7 million of unamortized leasing costs to amortization expense related to a customer in bankruptcy whose leases with us were rejected effective July 1, 2015 pursuant to an order made by the bankruptcy court, described below. Leasing costs incurred for the three and nine months ended September 30, 2015 and 2014 were as follows (in thousands):

	Three months ended September 30,				Nine months ended September 30,
	2015		2014		2015		2014
Leasing costs incurred for new leases	$	5	$	148	$	889	$	1,751
Leasing costs incurred for renewals	9		153		1,156		153
Total leasing costs incurred	$	14	$	301	$	2,045	$	1,904

Amortization of deferred leasing costs totaled $1.0 million for each of the three months ended September 30, 2015 and 2014, and $3.9 million and $3.0 million for the nine months ended September 30, 2015 and 2014, respectively, including the write-off described above. Balances, net of accumulated amortization, at September 30, 2015 and December 31, 2014 were as follows (in thousands):

	September 30, 2015			December 31, 2014
Leasing costs	$	48,315		$	52,358
Accumulated amortization	(29,001		)	(31,153		)
Leasing costs, net	$	19,314		$	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 September 30, 2015 and December 31, 2014, the fuel inventory was $4.5 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.

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

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

14

Balances, net of accumulated amortization, at September 30, 2015 and December 31, 2014 were as follows (in thousands):

	September 30, 2015			December 31, 2014
Lease contracts above market value	$	20,500		$	23,100
Accumulated amortization	(14,249		)	(15,046		)
Lease contracts above market value, net	$	6,251		$	8,054
Lease contracts below market value	$	24,175		$	39,375
Accumulated amortization	(19,704		)	(32,338		)
Lease contracts below market value, net	$	4,471		$	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 September 30, 2015 and December 31, 2014, we had one uncollectible account that consisted of a note receivable from a customer in bankruptcy. The note balance as of September 30, 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. Over the term of the note, we applied interest received to the note principal balance totaling $1.2 million. As of September 30, 2015 and December 31, 2014, respectively, we have established a reserve of $5.1 million and $4.9 million, including interest applied to principal. The note receivable, net of reserves and interest applied to the principal, was $1.4 million and $1.7 million as of September 30, 2015 and December 31, 2014, respectively. In October 2015, a sale of our bankrupt customer's east coast business was consummated, and we continue to be reasonably assured that we will be able to collect the balance of the note receivable, net of reserve, as a claim in the bankruptcy.

We also establish an appropriate allowance for doubtful accounts for receivables arising from the straight-lining of rents. These receivables arise from revenue recognized in excess of amounts currently due under the lease and are recorded as deferred rent in the accompanying consolidated balance sheets. As of December 31, 2014, we had reserves against deferred rent relating to the leases with the customer in bankruptcy of $3.7 million. Due to the rejection of leases by our bankrupt customer, we wrote off the reserved straight-line rent receivable in the second quarter and had no reserves against deferred rent as of September 30, 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

15

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 nine months ended September 30, 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.

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 ("FASB") 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. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line of credit arrangements, the SEC staff stated they would not object to an entity continuing to present line of credit issuance costs as an asset, regardless of whether there are any outstanding borrowings on the line of credit. Entities are required to apply ASU 2015-03 in the first quarter of 2016 and apply the guidance retrospectively to all prior periods presented. Early adoption is permitted.

In May 2014, the FASB 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 2018 and are assessing whether the new standard will have a material effect on our financial position or results of operations.

Outstanding Indebtedness

Unsecured Credit Facility

We have an unsecured revolving credit facility ("Unsecured Credit Facility") with a total commitment of $700 million, which was increased from $560 million in July 2015. 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 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 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 below.

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 September 30, 2015, a letter of credit totaling less than $0.1 million was outstanding under the facility. As of September 30, 2015, no amounts 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 September 30, 2015.

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;

19

• 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 September 30, 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.

		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 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 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

20

• 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 September 30, 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, ACC7 and CH2 data center facilities, 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:

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

21

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 September 30, 2015.

Unsecured Notes due 2023

On June 9, 2015, the Operating Partnership completed the sale of $250 million of 5.625% unsecured notes due 2023 (the "Unsecured Notes due 2023"). The Unsecured Notes due 2023 were issued at 99.205% and mature on June 15, 2023. We will pay interest on the Unsecured Notes due 2023 semi-annually, in arrears, on June 15th and December 15th of each year, beginning December 15, 2015.

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

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 CH2 Phase II, ACC7 Phase II and ACC7 Phase III data centers were in place as of September 30, 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 September 30, 2015, the CH2 Phase II control estimate was $17.8 million, of which $3.4 million has been incurred. An additional $8.6 million has been committed under this contract as of September 30, 2015. As of September 30, 2015, the ACC7 Phase II control estimate was $46.3 million, of which $37.2 million has been incurred. An additional $4.6 million has been committed under this contract as of September 30, 2015. As of September 30, 2015, the ACC7 Phase III control estimate was $73.4 million, of which $19.5 million has been incurred, and an additional $31.9 million has been committed as of September 30, 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. Messrs. 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

23

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 September 30, 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 September 30, 2015 and December 31, 2014 was $399.1 million and $513.1 million, respectively, based on the closing share price of DFT’s common stock of $25.88 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 nine months ended September 30, 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.

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 will expire on December 31, 2015. During the nine months ended September 30, 2015, DFT repurchased 1,002,610 shares of its common stock totaling $31.9 million, and $88.1 million is still available for repurchase under the program. All repurchased shares were retired immediately, and the Operating Partnership 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 first quarter of 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 first quarter of 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 first quarter of 2015 related to the accelerated vesting of these performance units.

Furthermore, $0.3 million was expensed during the first quarter of 2015 in connection with the accelerated vesting of certain unvested stock options held by Mr. Fateh. Mr. Fateh also received a cash severance payment of $1.3 million which was expensed during the first quarter of 2015 and paid during the third quarter.

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 September 30, 2015, 3,206,037 share equivalents were issued under the 2011 Plan, and the maximum aggregate amount of share equivalents remaining available for future issuance was 3,093,963.

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	(132,039	)	23.92
Forfeited	(7,582	)	28.63
Unvested balance at September 30, 2015	338,023		$	27.77

During the nine months ended September 30, 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 nine months ended September 30, 2015, 132,039 shares of restricted stock vested at a value of $4.1 million on the respective vesting dates.

As of September 30, 2015, total unearned compensation on restricted stock was $6.7 million, and the weighted average vesting period was 1.2 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 nine months ended September 30, 2015, no options were granted to employees.

A summary of our stock option activity under the applicable equity incentive plan for the nine months ended September 30, 2015 is presented in the tables below.

	Number of Options	Weighted Average Exercise Price

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 nine months ended September 30, 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 the nine months ended September 30, 2015, 4,225 performance units were forfeited with a weighted average fair value of $36.30 per unit. As of September 30, 2015, total unearned compensation on outstanding performance units was $2.1 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 1, 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 September 30, 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 Notes due 2023, Unsecured Term Loan, Unsecured Credit Facility and ACC3 Term Loan was $1,213.1 million with a fair value of $1,227.6 million based on Level 2 data. The Unsecured Notes due 2021 and Unsecured Notes due 2023 were valued based on Level 2 data which consisted of a quoted price from Bloomberg. We believe that the carrying values of our ACC3 Term Loan, Unsecured Credit Facility and Unsecured Term Loan approximate each of their fair values as of September 30, 2015. Each of these loans bears 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

Our Unsecured Notes due 2021 and Unsecured Notes due 2023 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, ACC7 and CH2 data center facilities, the ACC8 and CH3 land and the TRS (collectively, the "Subsidiary Non-Guarantors"). The following consolidating financial information sets forth the financial position as of September 30, 2015 and December 31, 2014 and the results of operations and cash flows for the three and nine months ended September 30, 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. (or "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 September 30, 2015, owned 80.9% of the common economic interest in, DuPont Fabros Technology, L.P. (or 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 the date of this filing, we owned and operated 12 data centers, eight of which are located in Northern Virginia, two 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) Stabilized operating properties are either 85% or more leased and commenced or have been in service for 24 months or greater.

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

(3) Percentage leased is expressed as a percentage of CRSF or critical load, as applicable, that is subject to an executed lease. Leases executed as of October 1, 2015 represent $297 million of base rent on a GAAP basis and $310 million of base rent on a cash basis over the next twelve months. Both amounts include $18 million of revenue from management fees over the next twelve months.

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

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

(6) As of October 29, 2015, ACC2 was 100% leased on a critical load and CRSF basis.

(7) In October 2015, new leases were executed with the purchaser of Net Data Centers' operations at our ACC4, ACC5, NJ1 Phase I and VA3 facilities. The new leases at ACC4, ACC5 and NJ1 Phase I are for the same amount of CRSF as the Net Data Centers leases, but are for a reduced amount of critical load. Giving effect to these decreases, ACC4, ACC5 and NJ1 Phase I were 97%, 96% and 52% leased and commenced on a critical load basis, respectively as of October 29, 2015. VA3 remains 95% leased and commenced on a critical load basis.

(8) As of October 29, 2015, ACC7 Phase I was 100% leased and commenced on a critical load and CRSF basis.

(9) As of October 29, 2015, CH2 Phase I was 100% leased and commenced on a critical load and CRSF basis.

Same Store Analysis

As of September 30, 2015

($ in thousands)

The following tables set forth an analysis of our same store and same store, same capital operating property portfolio for the three and nine months ended September 30, 2015. Same store properties represent those properties placed into service on or before January 1, 2014, which, as of September 30, 2015, include all of our operating properties except ACC7, due to its first phase being placed into service in July 2014. Accordingly, same store properties represented 236.9 MW, or 92%, of the 257.2 MW of operating properties in service as of September 30, 2015. Same store, same capital properties represent those operating properties placed into service on or before January 1, 2014 and have less than 10% of additional critical load developed after January 1, 2014. Accordingly, our same store, same capital properties include all of our operating properties with the exception of ACC7, for the reason described above, and SC1, due to phases IIA and IIB of this facility being placed into service in June 2014 and May 2015, respectively, which increased the critical load at SC1 by over 10%. Same store, same capital properties represented 200.3 MW, or 78%, of the 257.2 MW of operating properties in service as of September 30, 2015.

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

We use NOI and Cash NOI as supplemental performance measures because, in excluding depreciation and amortization 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).

(9) Amounts listed for gross building area, CRSF and critical load are current 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

44

space that they occupy. During the nine months ended September 30, 2015, we executed seven leases representing a total of 14.46 MW of critical load and 76,600 CRSF of space with a weighted average lease term of 7.1 years. These leases included the following:

• Four leases were at ACC7 Phase I and Phase II comprising 9.43 MW of critical load and 51,001 CRSF.

• One lease was at SC1 Phase IIB comprising 3.41 MW of critical load and 15,853 CRSF.

• One lease was at CH2 Phase I comprising 1.42 MW of critical load and 8,886 CRSF.

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

During the nine months ended September 30, 2015, we also extended the maturity of six leases by a weighted average of 2.9 years totaling 10.75 MW of critical load and 60,620 CRSF:

• Three extensions were at ACC4 totaling 4.55 MW and 21,600 CRSF.

• One extension was at ACC5 totaling 0.57 MW and 2,700 CRSF.

• One extension was at ACC6 totaling 4.33 MW and 22,000 CRSF.

• One extension was at VA3 totaling 1.30 MW and 14,320 CRSF.

In October 2015, we executed eight leases representing a total of 26.53 MW of critical load and 162,496 CRSF of space with a weighted average lease term of 6.1 years. These leases included the following:

• Two leases were at ACC7 Phase I and Phase II comprising 6.00 MW of critical load and 34,409 CRSF. These leases resulted in ACC7 Phase I being 100% leased and commenced on critical load and CRSF.

• One lease was at CH2 Phase I comprising 6.00 MW of critical load and 35,838 CRSF. This lease resulted in CH2 Phase I being 100% leased and commenced on critical load and CRSF.

• Four leases were executed with a new customer in the space formerly occupied by our bankrupt customer, Net Data Center, comprising an aggregate of 4.13 MW and 38,852 CRSF at ACC4, ACC5, NJ1 and VA3.

• One lease was at ACC2 comprising 10.4 MW and 53,397 CRSF, further described below.

Our lease with Yahoo! for the 10.4 MW of space at our ACC2 facility expired on September 30, 2015. The new lease is expected to commence in the first quarter of 2016, expires in March 2031 and includes early termination options in years five and ten, whereby the customer can terminate the lease early if it pays a termination penalty. This new lease will be accounted for as a five year lease under GAAP.

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. 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 5.5 years as of October 1, 2015. Approximately 9% 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 October 1, 2015, we had 38 customers with 113 lease expiration dates. Four of these leases were with our bankrupt customer, Net Data Centers, and were considered month to month until they were terminated on October 20, 2015 when we signed four new leases with a new customer, further described below. The four new leases expire in 2023.

Available Data Center Inventory and Current Development Projects

As of October 29, 2015, our operating portfolio was 97% leased and 93% commenced as measured by CRSF and 95% leased and 91% commenced as measured by critical load. The opportunity for revenue growth in the near term primarily depends on our ability to lease the 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.

As of October 29, 2015, only NJ1 had a significant amount of vacant space - 8.7 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 October 29, 2015, we had four data center facilities under development, as follows:

• ACC7 Phase II - 8.9 MW of available critical load, with completion expected in the fourth quarter of 2015. ACC7 Phase II was 67% pre-leased as of the date of this filing;

• ACC7 Phase III - 11.9 MW of available critical load, with completion expected in the second quarter of 2016;

•CH2 Phase II - 5.7 MW of available critical load, with completion expected in the second quarter of 2016; and

• CH2 Phase III, which was placed into development in October 2015 - 12.5 MW of available critical load, with completion expected in the third quarter of 2016.

Our three largest customers comprised 53% of our annualized base rent as of September 30, 2015. The first and third largest customers have early termination rights in certain of their leases, and we have reflected these leases in the Lease Expiration Table above at the early termination dates. As part of a new lease that our second largest customer signed with us in May 2015, this customer now has the right to individually decrease the term of the lease of each of nine other of its existing computer rooms in ACC5, each with 2.28 MW, provided the aggregate reduction in lease terms does not exceed 67 months, or an average of approximately seven months per computer room. We have reflected these leases in the Lease Expiration Table above using our best estimate of the allocation of the 67 month lease term reductions. 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. 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.

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 5.5 years as of October 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

46

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 six lease extensions executed during the nine months ended September 30, 2015 totaling 10.75 MW and 60,620 CRSF, described above, GAAP base rent is 5.4% higher than GAAP base rent prior to the extension, in the aggregate, on a straight-line basis. Compared to the cash base rental rates in effect when these extensions were each executed, cash base rents will be an average of 7.4% higher, in the aggregate, upon the expiration of the original lease terms.

As described above, in October 2015, we re-leased the entire 10.4 MW of space and 53,397 CRSF at ACC2 that was formerly occupied by Yahoo!. GAAP base rent, on a straight-line basis, is 12.6% lower under the terms of the new lease compared to the Yahoo! lease. Compared to the cash base rental rates in effect when the Yahoo! lease expired, cash base rents will be 41.4% lower under the terms of the new lease.

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 received payment for all rent obligations for March through June totaling $5.1 million in the aggregate. We did not recognize the base rent portions of these payments as

revenue, but instead applied them to the straight-line rent receivable balances for this customer.

Effective July 1, 2015, Net Data Centers was deemed to have rejected each of its leases with us. Accordingly, in June 2015, we wrote-off as a reduction of rental revenue $0.4 million of straight-line rents receivable, $0.1 million of unamortized lease inducements and $1.0 million of unamortized lease intangibles related to Net Data Center's leases with us, as well as $0.7 million of unamortized leasing commissions which were recorded to amortization expense.

A revenue sharing arrangement with Net Data Centers was approved by the bankruptcy court effective July 1, 2015, which allowed Net Data Centers to occupy the leased space in our data centers on a month-to-month basis until the earlier of January 31, 2016 or until other such conditions are met, while they worked to negotiate a sale. Under this arrangement, we received $2.7 million in the aggregate during the three months ended September 30, 2015, of which $1.7 million was used to pay down the remaining $1.7 million straight-line rents receivable balance for Net Data Centers that existed as of June 30, 2015. The remaining $1.0 million received was recognized as revenue during the three months ended September 30, 2015.

In October 2015, a sale of Net Data Centers' east coast business was consummated, and we entered into four new lease agreements with the purchaser, whose term of lease at each data center commenced on October 20, 2015 and expires on December 21, 2023, as follows:

Property	MW leased	CRSF Leased
ACC4	1.35	10,800
ACC5	0.33	1,930
NJ1 Phase I	1.15	11,000
VA3	1.30	15,122
Total	4.13	38,852

In the aggregate, the rent of the new leases compared to the Net Data Centers leases results in a 33.9% reduction in cash base rental rates and an 18.1% reduction in GAAP base rental rates. Also, the new customer leased 2.13 MW less than Net Data Centers’ leased MW, in the aggregate.

As of September 30, 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 September 30, 2015. The terms of this note require the payment of principal and interest through maturity on December 31, 2016. Net Data Centers has not made any payments on the note while in bankruptcy; however, we believe we will recover the unreserved portion of this note as a claim in bankruptcy.

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

47

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.

DFT is the sole general partner of the Operating Partnership and, as of September 30, 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 September 30, 2015 Compared to Three Months Ended September 30, 2014

Operating Revenue. Operating revenue for the three months ended September 30, 2015 was $115.3 million. This includes base rent of $76.8 million, which includes our management fee, tenant recoveries of $35.2 million and other revenue of $3.3 million, including revenue from a la carte projects for our customers performed by the TRS. This compares to revenue of $105.6 million for the three months ended September 30, 2014. The increase of $9.7 million, or 9.2%, was primarily due to increased revenue from placing ACC7 Phase I, CH2 Phase I, and SC1 Phase II into service, an increase in other income due to an increase in a la carte projects for our customers performed by the TRS and an increase in recoveries from tenants due to increased real estate taxes. These increases were partially offset by a $2.4 million decrease in revenue due to base rent and operating expense recovery revenue not being recognized for a bankrupt customer during the three months ended September 30, 2015.

Operating Expenses. Operating expenses for the three months ended September 30, 2015 were $72.4 million, compared to $64.1 million for the three months ended September 30, 2014. The increase of $8.3 million, or 12.9%, was primarily due to increased operating costs from placing ACC7 Phase I, CH2 Phase I and SC1 Phase II into service, $1.6 million of increased depreciation and amortization from placing ACC7 Phase I, CH2 Phase I and SC1 Phase II into service, an increase in other expenses of $1.4 million due to more a la carte projects for our customers performed by our TRS and increased real estate taxes of $1.1 million at SC1.

Interest Expense. Interest expense, including amortization of deferred financing costs, for the three months ended September 30, 2015 was $12.6 million compared to interest expense of $9.8 million for the three months ended September 30, 2014. Total interest incurred for the three months ended September 30, 2015 was $15.4 million, of which $2.8 million was capitalized, as compared to $11.7 million for the corresponding period in 2014, of which $1.8 million was capitalized. The increase in total interest was primarily due to increased borrowings to fund our development of data centers and higher rates due to the completion of an offering of Unsecured Notes due 2023 in June 2015, a portion of the proceeds of which were used to pay off of the outstanding balance of our line of credit.

Loss on Early Extinguishment of Debt. For the three months ended September 30, 2014, we incurred a loss of $1.4 million due to the refinancing of our Unsecured Term Loan in July 2014 that was treated as a partial extinguishment in accordance with GAAP.

Net Income Attributable to Redeemable Noncontrolling interests – Operating Partnership (DFT only). Net income attributable to redeemable noncontrolling interests – operating partnership was $4.5 million for each of the three months ended September 30, 2014 and 2015, respectively.

Net Income Attributable to Common Shares. Net income attributable to common shares for the three months ended September 30, 2015 was $19.1 million compared to $19.0 million for the three months ended September 30, 2014. The     increase of $0.1 million was primarily due to higher revenue, partially offset by higher interest expense and higher operating expenses, each described above.

Nine Months Ended September 30, 2015 Compared to Nine Months Ended September 30, 2014

Operating Revenue. Operating revenue for the nine months ended September 30, 2015 was $336.5 million. This includes base rent of $221.0 million, which includes our management fee, tenant recoveries of $103.0 million and other revenue of $12.5 million, including revenue from a la carte projects for our customers performed by the TRS. This compares to revenue of $309.6 million for the nine months ended September 30, 2014. The increase of $26.9 million, or 8.7%, was primarily due to increased revenue from placing ACC7 Phase I, CH2 Phase I and SC1 Phase II into service, new leases commencing at ACC5, NJ1 Phase I, and VA3, an increase in a la carte projects for our customers performed by the TRS and an increase in recoveries from tenants due to increased real estate taxes. These increases were partially offset by a $9.4 million decrease in revenue due to base rent revenue not being recognized for a bankrupt customer during the nine months ended September 30, 2015, as well as $1.5 million in write-offs during the nine months ended September 30, 2015 of this customer's straight-line rents receivable, unamortized lease intangible and unamortized lease inducements.

Operating Expenses. Operating expenses for the nine months ended September 30, 2015 were $217.4 million, compared to $186.3 million for the nine months ended September 30, 2014. The increase of $31.1 million, or 16.7%, was primarily due to an $11.8 million increase in other expenses primarily due to increased a la carte expenses as a result of an increase in a la carte projects and a $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 $6.0 million of increased depreciation and amortization from the opening of ACC7 Phase I, CH2 Phase I and SC1 Phase II, increased real estate taxes of $4.1 million at SC1 and increased operating costs from placing ACC7 Phase I, CH2 Phase I and SC1 Phase II into service.

Interest Expense. Interest expense, including amortization of deferred financing costs, for the nine months ended September 30, 2015 was $31.3 million compared to interest expense of $26.8 million for the nine months ended September 30, 2014. Total interest incurred for the nine months ended September 30, 2015 was $40.4 million, of which $9.1 million was capitalized, as compared to $35.1 million for the corresponding period in 2014, of which $8.3 million was capitalized. The increase in total interest was primarily due to increased borrowings to fund our development of data centers and higher rates due to the completion of an offering of Unsecured Notes due 2023 in June 2015, a portion of the proceeds of which were used to pay off the outstanding balance of our line of credit.

Loss on Early Extinguishment of Debt. For the nine months ended September 30, 2014, we incurred a loss of $1.7 million comprised of the write-off of $0.3 million of loan fees related to the refinancing of our Unsecured Credit Facility in May 2014 and a loss of $1.4 million due to the refinancing of our Unsecured Term Loan in July 2014 that was treated as a partial extinguishment in accordance with GAAP. 

Net Income Attributable to Redeemable Noncontrolling interests – Operating Partnership (DFT only). Net income attributable to redeemable noncontrolling interests – operating partnership for the nine months ended September 30, 2015 was $12.9 million compared to $14.3 million for the nine months ended September 30, 2014. The decrease of $1.4 million was primarily due to a decrease in net income.

Net Income Attributable to Common Shares. Net income attributable to common shares for the nine months ended September 30, 2015 was $54.5 million compared to $60.1 million for the nine months ended September 30, 2014. The decrease of $5.6 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 nine months ended September 30, 2015 was a $4.2 million bank account at DFT that is not part of the Operating Partnership.

Nine Months Ended September 30, 2015 Compared to Nine Months Ended September 30, 2014

Net cash provided by operating activities increased by $19.6 million, or 11.4%, to $191.4 million for the nine months ended September 30, 2015, as compared to $171.8 million for the corresponding period in 2014. The increase was primarily due to higher cash rents from tenants and lower prepaid expenses.

Net cash used in investing activities decreased by $24.3 million to $174.4 million for the nine months ended September 30, 2015 compared to $198.7 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 nine months ended September 30, 2015,

49

cash used for development was primarily for the construction of CH2 Phase I, CH2 Phase II, ACC7 Phase II, ACC7 Phase III and SC1 Phase IIB and an $8.6 million purchase of land in Elk Grove Village, Illinois that will be used for the future development of CH3. During the nine months ended September 30, 2014, the majority of development cash used was for SC1 Phase IIA, ACC7 Phase I and CH2 Phase I.

Net cash provided by financing activities was $21.2 million for the nine months ended September 30, 2015 compared to net cash used in financing activities of $3.1 million in the corresponding period in 2014. Net cash provided by financing activities for the nine months ended September 30, 2015 consisted of $248.0 million in proceeds from the issuance of our Unsecured Notes due 2023 in June 2015 and $120 million of advances under our Unsecured Credit Facility, partially offset by $180.0 million in repayments of on our Unsecured Credit Facility, $122.5 million paid for dividends and distributions, $31.9 million in repurchases of our common stock, $7.6 million of cash used in connection with the payment of withholding taxes for employees upon the vesting of performance shares, restricted common stock and grants of unrestricted common stock and $4.7 million in financing costs paid in connection with the issuance of the Unsecured Notes due 2023 and the amendment of our Unsecured Credit Facility. Net cash used by financing activities for the nine months ended September 30, 2014 consisted of $97.6 million paid for dividends and distributions and the payment of $3.8 million of financing costs related to the amendments of the Unsecured Credit Facility, the ACC3 Term Loan and the Unsecured Term Loan, partially offset by $96.0 million of proceeds from the final draw of the Unsecured Term Loan and $2.3 million of proceeds received from stock option exercises, net.

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.

For the remainder of 2015 and in 2016, we expect to meet our liquidity needs from cash available on our balance sheet, cash provided by operating activities and external sources. We fund a portion of the cost of data center development from additional capital because cash on hand and cash provided by operating activities are 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 under our outstanding indebtedness, our

50

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 February 26, 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 indentures that govern our Unsecured Notes due 2021 and Unsecured Notes due 2023 limit DFT’s ability to pay dividends, but allow DFT to pay the minimum necessary to meet its REIT income distribution requirements.

A summary of our total debt as of September 30, 2015 and December 31, 2014 is as follows:

Outstanding Indebtedness

Unsecured Credit Facility

We have an unsecured revolving credit facility ("Unsecured Credit Facility") with a total commitment of $700 million, which was increased from $560 million in July 2015. 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.

51

		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 below.

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 September 30, 2015, a letter of credit totaling less than $0.1 million was outstanding under the facility. As of September 30, 2015, no amounts 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 September 30, 2015.

52

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 September 30, 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.

		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).

53

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 September 30, 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, ACC7 and CH2 data center facilities, 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

54

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 September 30, 2015.

Unsecured Notes due 2023

On June 9, 2015, the Operating Partnership completed the sale of $250 million of 5.625% unsecured notes due 2023 (the "Unsecured Notes due 2023"). The Unsecured Notes due 2023 were issued at 99.205% and mature on June 15, 2023. We will pay interest on the Unsecured Notes due 2023 semi-annually, in arrears, on June 15th and December 15th of each year, beginning December 15, 2015.

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

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

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

Year	Redemption Price
2018	104.219	%
2019	102.813	%
2020	101.406	%
2021 and thereafter	100.000	%

If there is a change of control (as defined in the indenture governing the Unsecured Notes due 2023) of the Operating Partnership or DFT, we must offer to purchase the Unsecured Notes due 2023 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 2023 at 100% of the principal amount thereof, plus accrued and unpaid interest.

The Unsecured Notes due 2023 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 2023 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 2023 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 2023 or the trustee may declare the Unsecured Notes due 2023 due and immediately payable. We were in compliance with all covenants under the Unsecured Notes due 2023 as of September 30, 2015.

56

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

We 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 the accompanying consolidated 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 ("FASB") 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. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line of credit arrangements, the SEC staff stated they would not object to an entity continuing to present line of credit issuance costs as an asset, regardless of whether there are any outstanding borrowings on the line of credit. Entities are required to apply ASU 2015-03 in the first quarter of 2016 and apply the guidance retrospectively to all prior periods presented. Early adoption is permitted.

In May 2014, the FASB 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 2018 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 September 30, 2015 would decrease future net income and cash flows by $3.7 million annually less the impact of capitalization of interest incurred on net income. Because one month LIBOR was approximately 0.20% at September 30, 2015, a decrease of 0.20% would increase future net income and cash flows by $0.7 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 September 30, 2015, 70% 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.

Significant Accounting Policies

Basis of Presentation

This report combines the quarterly reports on Form 10-Q for the quarter ended September 30, 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 September 30, 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 and nine months ended September 30, 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 $25.3 million and $23.7 million for the three months ended September 30, 2015 and 2014, respectively, and $73.4 million and $68.4 million for the nine months ended September 30, 2015 and 2014, respectively. Included in these amounts is amortization expense related to tenant origination costs, which was $0.5 million and $0.8 million for the three months ended September 30, 2015 and 2014, respectively, and $1.7 million and $2.4 million for the nine months ended September 30, 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 nine months ended September 30, 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 September 30, 2015 and December 31, 2014 were as follows (in thousands):

	September 30, 2015			December 31, 2014
Financing costs	$	28,721		$	24,110
Accumulated amortization	(9,525		)	(6,820		)
Financing costs, net	$	19,196		$	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. In June 2015, we wrote off $0.7 million of unamortized leasing costs to amortization expense related to a customer in bankruptcy whose leases with us were rejected effective July 1, 2015 pursuant to an order made by the bankruptcy court, described below. Leasing costs incurred for the three and nine months ended September 30, 2015 and 2014 were as follows (in thousands):

	Three months ended September 30,				Nine months ended September 30,
	2015		2014		2015		2014
Leasing costs incurred for new leases	$	5	$	148	$	889	$	1,751
Leasing costs incurred for renewals	9		153		1,156		153
Total leasing costs incurred	$	14	$	301	$	2,045	$	1,904

Amortization of deferred leasing costs totaled $1.0 million for each of the three months ended September 30, 2015 and 2014, and $3.9 million and $3.0 million for the nine months ended September 30, 2015 and 2014, respectively, including the write-off described above. Balances, net of accumulated amortization, at September 30, 2015 and December 31, 2014 were as follows (in thousands):

	September 30, 2015			December 31, 2014
Leasing costs	$	48,315		$	52,358
Accumulated amortization	(29,001		)	(31,153		)
Leasing costs, net	$	19,314		$	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 September 30, 2015 and December 31, 2014, the fuel inventory was $4.5 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.

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

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

Balances, net of accumulated amortization, at September 30, 2015 and December 31, 2014 were as follows (in thousands):

	September 30, 2015			December 31, 2014
Lease contracts above market value	$	20,500		$	23,100
Accumulated amortization	(14,249		)	(15,046		)
Lease contracts above market value, net	$	6,251		$	8,054
Lease contracts below market value	$	24,175		$	39,375
Accumulated amortization	(19,704		)	(32,338		)
Lease contracts below market value, net	$	4,471		$	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 September 30, 2015 and December 31, 2014, we had one uncollectible account that consisted of a note receivable from a customer in bankruptcy. The note balance as of September 30, 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. Over the term of the note, we applied interest received to the note principal balance totaling $1.2 million. As of September 30, 2015 and December 31, 2014, respectively, we have established a reserve of $5.1 million and $4.9 million, including interest applied to principal. The note receivable, net of reserves and interest applied to the principal, was $1.4 million and $1.7 million as of September 30, 2015 and December 31, 2014, respectively. In October 2015, a sale of our bankrupt customer's east coast business was consummated, and we continue to be reasonably assured that we will be able to collect the balance of the note receivable, net of reserve, as a claim in the bankruptcy.

We also establish an appropriate allowance for doubtful accounts for receivables arising from the straight-lining of rents. These receivables arise from revenue recognized in excess of amounts currently due under the lease and are recorded as deferred rent in the accompanying consolidated balance sheets. As of December 31, 2014, we had reserves against deferred rent relating to the leases with the customer in bankruptcy of $3.7 million. Due to the rejection of leases by our bankrupt customer, we wrote off the reserved straight-line rent receivable in the second quarter and had no reserves against deferred rent as of September 30, 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 nine months ended September 30, 2015 (dollars in thousands):

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

Net income is allocated to controlling interests and redeemable noncontrolling interests – operating partnership in accordance with the limited partnership agreement of the Operating Partnership. The following is a summary of net income attributable to controlling interests and transfers to redeemable noncontrolling interests – operating partnership for the three and nine months ended September 30, 2015 and 2014 (dollars in thousands):

	Three months ended September 30,					Nine months ended September 30,

	$	78,964	$	24,152		$	182,523	$	45,293

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 ("FASB") 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. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line of credit arrangements, the SEC staff stated they would not object to an entity continuing to present line of credit issuance costs as an asset, regardless of whether there are any outstanding borrowings on the line of credit. Entities are required to apply ASU 2015-03 in the first quarter of 2016 and apply the guidance retrospectively to all prior periods presented. Early adoption is permitted.

In May 2014, the FASB 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 2018 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 CH2 Phase II, ACC7 Phase II and ACC7 Phase III data centers were in place as of September 30, 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 September 30, 2015, the CH2 Phase II control estimate was $17.8 million, of which $3.4 million has been incurred. An additional $8.6 million has been committed under this contract as of September 30, 2015. As of September 30, 2015, the ACC7 Phase II control estimate was $46.3 million, of which $37.2 million has been incurred. An additional $4.6 million has been committed under this contract as of September 30, 2015. As of September 30, 2015, the ACC7 Phase III control estimate was $73.4 million, of which $19.5 million has been incurred, and an additional $31.9 million has been committed as of September 30, 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. Messrs. 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 September 30, 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

Unsecured Credit Facility

We have an unsecured revolving credit facility ("Unsecured Credit Facility") with a total commitment of $700 million, which was increased from $560 million in July 2015. 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 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 below.

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 September 30, 2015, a letter of credit totaling less than $0.1 million was outstanding under the facility. As of September 30, 2015, no amounts 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 September 30, 2015.

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 September 30, 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.

		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 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 September 30, 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, ACC7 and CH2 data center facilities, the ACC8 land, our taxable REIT subsidiary, DF Technical Services, LLC and our property management subsidiary, DF Property Management LLC.

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:

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.

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 September 30, 2015.

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 September 30, 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 Notes due 2023, Unsecured Term Loan, Unsecured Credit Facility and ACC3 Term Loan was $1,213.1 million with a fair value of $1,227.6 million based on Level 2 data. The Unsecured Notes due 2021 and Unsecured Notes due 2023 were valued based on Level 2 data which consisted of a quoted price from Bloomberg. We believe that the carrying values of our ACC3 Term Loan, Unsecured Credit Facility and Unsecured Term Loan approximate each of their fair values as of September 30, 2015. Each of these loans bears interest at LIBOR plus a spread that is consistent with current market conditions.

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 October 2, 2015. This dividend was paid on October 15, 2015.

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 will expire on December 31, 2015. During the nine months ended September 30, 2015, DFT repurchased 1,002,610 shares of its common stock totaling $31.9 million, and $88.1 million is still available for repurchase under the program. All repurchased shares were retired immediately, and the Operating Partnership 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 first quarter of 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 first quarter of 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 first quarter of 2015 related to the accelerated vesting of these performance units.

Furthermore, $0.3 million was expensed during the first quarter of 2015 in connection with the accelerated vesting of certain unvested stock options held by Mr. Fateh. Mr. Fateh also received a cash severance payment of $1.3 million which was expensed during the first quarter of 2015 and paid during the third quarter.

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 September 30, 2015 and December 31, 2014 was $399.1 million and $513.1 million, respectively, based on the closing share price of DFT’s common stock of $25.88 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 nine months ended September 30, 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 September 30, 2015, 3,206,037 share equivalents were issued under the 2011 Plan, and the maximum aggregate amount of share equivalents remaining available for future issuance was 3,093,963.

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

Forfeited	(7,582	)	28.63
Unvested balance at September 30, 2015	338,023		$	27.77

During the nine months ended September 30, 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 nine months ended September 30, 2015, 132,039 shares of restricted stock vested at a value of $4.1 million on the respective vesting dates.

As of September 30, 2015, total unearned compensation on restricted stock was $6.7 million, and the weighted average vesting period was 1.2 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 nine months ended September 30, 2015, no options were granted to employees.

A summary of our stock option activity under the applicable equity incentive plan for the nine months ended September 30, 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 nine months ended September 30, 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 September 30, 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 September 30, 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 and nine months ended September 30, 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 $25.3 million and $23.7 million for the three months ended September 30, 2015 and 2014, respectively, and $73.4 million and $68.4 million for the nine months ended September 30, 2015 and 2014, respectively. Included in these amounts is amortization expense related to tenant origination costs, which was $0.5 million and $0.8 million for the three months ended September 30, 2015 and 2014, respectively, and $1.7 million and $2.4 million for the nine months ended September 30, 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 nine months ended September 30, 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 September 30, 2015 and December 31, 2014 were as follows (in thousands):

	September 30, 2015			December 31, 2014
Financing costs	$	28,721		$	24,110
Accumulated amortization	(9,525		)	(6,820		)
Financing costs, net	$	19,196		$	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. In June 2015, we wrote off $0.7 million of unamortized leasing costs to amortization expense related to a customer in bankruptcy whose leases with us were rejected effective July 1, 2015 pursuant to an order made by the bankruptcy court, described below. Leasing costs incurred for the three and nine months ended September 30, 2015 and 2014 were as follows (in thousands):

	Three months ended September 30,				Nine months ended September 30,
	2015		2014		2015		2014
Leasing costs incurred for new leases	$	5	$	148	$	889	$	1,751
Leasing costs incurred for renewals	9		153		1,156		153
Total leasing costs incurred	$	14	$	301	$	2,045	$	1,904

Amortization of deferred leasing costs totaled $1.0 million for each of the three months ended September 30, 2015 and 2014, and $3.9 million and $3.0 million for the nine months ended September 30, 2015 and 2014, respectively, including the write-off described above. Balances, net of accumulated amortization, at September 30, 2015 and December 31, 2014 were as follows (in thousands):

	September 30, 2015			December 31, 2014
Leasing costs	$	48,315		$	52,358
Accumulated amortization	(29,001		)	(31,153		)
Leasing costs, net	$	19,314		$	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 September 30, 2015 and December 31, 2014, the fuel inventory was $4.5 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.

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

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

Balances, net of accumulated amortization, at September 30, 2015 and December 31, 2014 were as follows (in thousands):

	September 30, 2015			December 31, 2014
Lease contracts above market value	$	20,500		$	23,100
Accumulated amortization	(14,249		)	(15,046		)
Lease contracts above market value, net	$	6,251		$	8,054
Lease contracts below market value	$	24,175		$	39,375
Accumulated amortization	(19,704		)	(32,338		)
Lease contracts below market value, net	$	4,471		$	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 September 30, 2015 and December 31, 2014, we had one uncollectible account that consisted of a note receivable from a customer in bankruptcy. The note balance as of September 30, 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. Over the term of the note, we applied interest received to the note principal balance totaling $1.2 million. As of September 30, 2015 and December 31, 2014, respectively, we have established a reserve of $5.1 million and $4.9 million, including interest applied to principal. The note receivable, net of reserves and interest applied to the principal, was $1.4 million and $1.7 million as of September 30, 2015 and December 31, 2014, respectively. In October 2015, a sale of our bankrupt customer's east coast business was consummated, and we continue to be reasonably assured that we will be able to collect the balance of the note receivable, net of reserve, as a claim in the bankruptcy.

We also establish an appropriate allowance for doubtful accounts for receivables arising from the straight-lining of rents. These receivables arise from revenue recognized in excess of amounts currently due under the lease and are recorded as deferred rent in the accompanying consolidated balance sheets. As of December 31, 2014, we had reserves against deferred rent relating to the leases with the customer in bankruptcy of $3.7 million. Due to the rejection of leases by our bankrupt customer, we wrote off the reserved straight-line rent receivable in the second quarter and had no reserves against deferred rent as of September 30, 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 nine months ended September 30, 2015 (dollars in thousands):

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

Net income is allocated to controlling interests and redeemable noncontrolling interests – operating partnership in accordance with the limited partnership agreement of the Operating Partnership. The following is a summary of net income attributable to controlling interests and transfers to redeemable noncontrolling interests – operating partnership for the three and nine months ended September 30, 2015 and 2014 (dollars in thousands):

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 using the two class method.

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.

Recently Issued Accounting Pronouncements, Policy [Policy Text Block]

Recently Issued Accounting Pronouncements

In March 2015, the Financial Accounting Standards Board ("FASB") 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. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line of credit arrangements, the SEC staff stated they would not object to an entity continuing to present line of credit issuance costs as an asset, regardless of whether there are any outstanding borrowings on the line of credit. Entities are required to apply ASU 2015-03 in the first quarter of 2016 and apply the guidance retrospectively to all prior periods presented. Early adoption is permitted.

In May 2014, the FASB 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 2018 and are assessing whether the new standard will have a material effect on our financial position or results of operations.
