NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

QTS Realty Trust, Inc. (the “Company”) through its controlling interest in QualityTech, L.P. (the “Operating Partnership”) and the subsidiaries of the Operating Partnership, is engaged in the business of owning, acquiring, redeveloping and managing multi-tenant data centers. As of March 31, 2014 the Company’s portfolio consists of 10 properties with data centers located throughout the continental United States.

The Company was formed as a Maryland corporation on May 17, 2013. On October 15, 2013, the Company completed its initial public offering of 14,087,500 shares of Class A common stock, $0.01 par value per share (the “IPO”), including shares issued pursuant to the underwriters’ option to purchase additional shares, which was exercised in full, and received net proceeds of approximately $279 million. The Company intends to elect to be taxed as a real estate investment trust (“REIT”), for U.S. federal income tax purposes, commencing with its taxable year ended December 31, 2013.

Concurrently with the completion of the IPO, the Company consummated a series of transactions, including the merger of General Atlantic REIT, Inc. with the Company, pursuant to which it became the sole general partner and majority owner of the Quality Tech, LP, a Delaware limited partnership (the “Operating Partnership”). The Company contributed the net proceeds received from the IPO to the Operating Partnership in exchange for partnership units therein. As of March 31, 2014, the Company owned approximately 78.8% of the interests in the Operating Partnership. Substantially all of the Company’s assets are held by, and the Company’s operations are conducted through, the Operating Partnership. The Company’s interest in the Operating Partnership entitles the Company to share in cash distributions from, and in the profits and losses of, the Operating Partnership in proportion to the Company’s percentage ownership. As the sole general partner of the Operating Partnership, the Company generally has the exclusive power under the partnership agreement to manage and conduct the Operating Partnership’s business and affairs, subject to certain limited approval and voting rights of the limited partners. The Company’s board of directors manages the Company’s business and affairs.

2. Summary of Significant Accounting Policies

Basis of Presentation – The accompanying financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included.

The Interim Condensed Consolidated Statement of Operations and Comprehensive Income and the Statement of Cash Flows of the Company for the three months ended March 31, 2014 and the Balance Sheets as of March 31, 2014 and December 31, 2013 present the accounts of QTS Realty Trust, Inc. and its majority owned subsidiaries. The Interim Condensed Consolidated Statement of Operations and Comprehensive Income and the Statement of Cash Flows for the three months ended March 31, 2013 present the accounts of QualityTech, LP and its majority owned subsidiaries (the “Historical Predecessor”).

Use of Estimates – The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of fixed assets, allowances for doubtful accounts and deferred tax assets and the valuation of derivatives, real estate assets, acquired intangible assets and certain accruals.

Principles of Consolidation – The consolidated financial statements include the accounts of QTS Realty Trust, Inc. and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the financial statements.

Real Estate Assets – Real estate assets are reported at cost. All capital improvements for the income-producing properties that extend their useful lives are capitalized to individual property improvements and depreciated over their estimated useful lives. Depreciation is generally provided on a straight-line basis over 40 years from the date the property was placed in service. Property improvements are depreciated on a straight-line basis over the life of the respective improvement ranging from 20 to 40 years from the date the components were placed in service. Leasehold improvements are depreciated over the lesser of 20 years or through the end of the respective life of the lease. Repairs and maintenance costs are expensed as incurred. The aggregate depreciation charged to operations was $10.2 million and $8.5 million for the three months ended March 31, 2014 and 2013, respectively. The Company capitalizes certain development costs, including internal costs incurred in connection with development. The capitalization of costs during the construction period (including interest and related loan fees, property taxes and other direct and indirect costs) begins when development efforts commence and ends when the asset is ready for its intended use. Capitalization of such costs, excluding interest, aggregated to $2.2 million and $1.7 million for the three months ended March 31, 2014 and 2013, respectively. Interest is capitalized during the period of development by first applying the Company’s actual borrowing rate on the related asset and second, to the extent necessary, by applying the Company’s weighted average effective borrowing rate to the actual development and other costs expended during the construction period. Interest is capitalized until the property is ready for its intended use. Interest costs capitalized totaled $1.6 million and $1.0 million for the three months ended March 31, 2014 and 2013, respectively.

- 7 -

Acquisition of Real Estate – Acquisitions of real estate are either accounted for as asset acquisitions or business combinations depending on facts and circumstances. Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired in accordance to the accounting requirements of ASC 805, Business Combinations, which requires the recording of net assets of acquired businesses at fair value. The fair value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and improvements, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, value of in-place leases and value of customer relationships.

In developing estimates of fair value of acquired assets and assumed liabilities, management analyzed a variety of factors including market data, estimated future cash flows of the acquired operations, industry growth rates, current replacement cost for fixed assets and market rate assumptions for contractual obligations. Such a valuation requires management to make significant estimates and assumptions, particularly with respect to the intangible assets.

Intangible assets and liabilities include in-place leases and customer relationships.

Acquired in-place leases are amortized as amortization expense on a straight-line basis over the remaining life of the underlying leases. Amortization of acquired in place lease costs, including write-offs for terminated leases totaled $0.6 million and $0.6 million for the three months ended March 31, 2014 and 2013, respectively.

Acquired customer relationships are amortized as amortization expense on a straight-line basis over the expected life of the customer relationship. Amortization of acquired customer relationships totaled $0.3 million and $0.4 million for the three months ended March 31, 2014 and 2013, respectively.

Impairment of Long-Lived and Intangible Assets – The Company reviews its long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Recoverability of assets to be held and used is generally measured by comparison of the carrying amount to the future net cash flows, undiscounted and without interest, expected to be generated by the asset group. If the net carrying value of the asset exceeds the value of the undiscounted cash flows, the fair value of the asset is assessed and may be considered impaired. An impairment loss is recognized based on the excess of the carrying amount of the impaired asset over its fair value. No impairment losses were recorded for the three months ended March 31, 2014 and 2013, respectively.

Cash and Cash Equivalents – The Company considers all demand deposits and money market accounts purchased with a maturity date of three months or less at the date of purchase to be cash equivalents. The Company’s account balances at one or more institutions periodically exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is concentration of credit risk related to amounts on deposit in excess of FDIC coverage. The Company mitigates this risk by depositing a majority of its funds with several major financial institutions. The Company also has not experienced any losses and, therefore, does not believe that the risk is significant.

Deferred Costs – Deferred costs, net, on the Company’s balance sheets include both financing costs and leasing costs.

Deferred financing costs represent fees and other costs incurred in connection with obtaining debt and are amortized over the term of the loan and are included in interest expense. Amortization of the deferred financing costs was $0.6 million and $0.9 million for the three months ended March 31, 2014 and 2013, respectively. In addition, during the three months ended March 31, 2013, the Company wrote off unamortized financing costs of $1.1 million in connection with an asset securitization which the Company did not pursue due to the expansion of the credit facility. Deferred financing costs, net of accumulated amortization are as follows:

	March 31,
	2014			December 31,
(dollars in thousands)	(unaudited)			2013
Deferred financing costs	$	9,526		$	9,159
Accumulated amortization		(2,450	)		(1,867	)
Deferred financing costs, net	$	7,076		$	7,292

- 8 -

Deferred leasing costs consist of external fees and internal costs incurred in the successful negotiations of leases and 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. Amortization of deferred leasing costs totaled $1.3 million and $1.0 million for the three months ended March 31, 2014 and 2013, respectively. Deferred leasing costs, net of accumulated amortization are as follows:

	March 31,
	2014			December 31,
(dollars in thousands)	(unaudited)			2013
Deferred leasing costs	$	19,282		$	17,374
Accumulated amortization		(7,201	)		(5,516	)
Deferred leasing costs, net	$	12,081		$	11,858

Advance Rents and Security Deposits – Advance rents, typically prepayment of the following month’s rent, consist of payments received from customers prior to the time they are earned and are recognized as revenue in subsequent periods when earned. Security deposits are collected from customers at the lease origination and are generally refunded to customers upon lease expiration.

Deferred Income – Deferred income generally results from non-refundable charges paid by the customer at lease inception to prepare their space for occupancy. The Company records this initial payment, commonly referred to as set-up fees, as a deferred income liability which amortizes into rental revenue over the term of the related lease on a straight-line basis. Deferred income was $8.1 million and $7.9 million as of March 31, 2014 and December 31, 2013, respectively. Additionally, $1.2 million and $1.1 million of deferred income was amortized into revenue for the three months ended March 31, 2014 and 2013, respectively.

Interest Rate Derivative Instruments – The Company utilizes derivatives to manage its interest rate exposure. During February 2012, the Company entered into interest rate swaps with a notional amount of $150 million which are cash flow hedges and qualify for hedge accounting. For these hedges, the effective portion of the change in fair value is recognized through other comprehensive income or loss. Amounts are reclassified out of other comprehensive income (loss) as the hedged item is recognized in earnings, either for ineffectiveness or for amounts paid relating to the hedge. As there was no ineffectiveness recorded in the periods presented, the Company has reflected the change in the fair value of the instrument in other comprehensive income (loss). For the ineffective portions of qualifying hedges, the change in fair value is recorded through interest expense in the respective period.

Equity-based Compensation –All equity-based compensation is measured at fair value on the grant date or date of modification, as applicable, and recognized in earnings over the requisite service period. Depending upon the settlement terms of the awards, all or a portion of the fair value of equity-based awards may be presented as a liability or as equity in the consolidated balance sheets. Equity-based compensation costs are measured based upon their estimated fair value on the date of grant or modification. Equity-based compensation expense net of forfeited and repurchased awards acquired of $0.9 million and $0.4 million was recorded for the three months ended March 31, 2014 and 2013, respectively.

Rental Revenue – The Company, as a lessor, has retained substantially all of the risks and benefits of ownership and accounts for its leases as operating leases. For lease agreements that provide for scheduled 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 has been provided to the customer. The amount of the straight-line rent receivable on the balance sheets included in rents and other receivables, net was $3.1 million and $2.9 million as of March 31, 2014 and December 31, 2013, respectively. Rental revenue also includes amortization of set-up fees which are amortized over the term of the respective lease as discussed above.

Allowance for Uncollectible Accounts Receivable – Rents receivable are recognized when due and are carried at cost, less an allowance for doubtful accounts. The Company records a provision for losses on rents receivable equal to the estimated uncollectible accounts, which is based on management’s historical experience and a review of the current status of the Company’s receivables. As necessary, the Company also establishes an appropriate allowance for doubtful accounts for receivables arising from the straight-lining of rents. The aggregate allowance for doubtful accounts was $1.3 million and $0.9 million as of March 31, 2014 and December 31, 2013, respectively.

Capital Lease – The Company evaluates leased real estate to determine whether the lease should be classified as a capital or operating lease in accordance with U.S GAAP.

The Company periodically enters into capital leases for certain equipment. The outstanding liabilities for the capital leases were $2.7 million and $2.5 million as of March 31, 2014 and December 31, 2013, respectively. Depreciation related to the associated assets is included in depreciation and amortization expense in the Statements of Operations and Comprehensive Income (Loss).

Recoveries from Customers – Certain customer leases contain provisions under which the customers reimburse the Company for a portion of the property’s real estate taxes, insurance and other operating expenses, which include certain power and cooling-related charges. The reimbursements are included in revenue as recoveries from customers in the Statements of Operations and Comprehensive Income (Loss) in the period the applicable expenditures are incurred. Certain customer leases are structured to provide a fixed monthly billing amount that includes an estimate of various operating expenses, with all revenue from such leases included in rental revenues.

- 9 -

Cloud and Managed Services Revenue – The Company may provide both its cloud product and use of its managed services to its customers on an individual or combined basis. Service fee revenue is recognized as the revenue is earned, which generally coincides with the services being provided.

Segment Information – The Company manages its business as one operating segment and thus one reportable segment consisting of a portfolio of investments in data centers located in the United States.

Customer Concentrations – As of March 31, 2014, two of the Company’s customers represented 8.0% and 5.5%, respectively, of its total monthly rental revenue. No other customers exceeded 5% of total monthly rental revenue.

As of March 31, 2014, six of the Company’s customers exceeded 5% of total accounts receivable. In aggregate, these six customers accounted for 39.5% of total accounts receivable. None of these six customers individually exceeded 10% of total accounts receivable.

Income Taxes – The Company is obligated to comply with Internal Revenue Service real estate investment trust (“IRS REIT”) tax regulations in accordance with the unit holders’ agreement. In order to comply with this obligation, the Company elected for one of its existing subsidiaries to be taxed as a taxable REIT subsidiary under the IRS REIT tax regulations. The taxable REIT subsidiary is allocated income and expense based on IRS REIT tax regulations.

For the taxable REIT subsidiary, income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company’s tax provision has not changed materially subsequent to December 31, 2013. The Company is not currently under examination by the Internal Revenue Service.

Fair Value Measurements – ASC Topic 820 emphasizes that fair-value is a market-based measurement, not an entity-specific measurement. Therefore, a fair-value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair-value measurements, a fair-value hierarchy is established that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

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

Financial assets and liabilities measured at fair value in the financial statements on a recurring basis consist of the Company’s derivatives. The fair values of the derivatives are determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. The analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves (“significant other observable inputs”). The fair value calculation also includes an amount for risk of non-performance using “significant unobservable inputs” such as estimates of current credit spreads to evaluate the likelihood of default. The Company has concluded as of March 31, 2014 and December 31, 2013 that the fair value associated to “significant unobservable inputs” for risk of non-performance was insignificant to the overall fair value of the derivative agreements and, as a result, have determined that the relevant inputs for purposes of calculating the fair value of the derivative agreements, in their entirety, were based upon “significant other observable inputs.” The Company determined the fair value of derivatives using level 2 inputs. These methods of assessing fair value result in a general approximation of value, and such value may never be realized.

The Company’s financial instruments held at fair value are presented below as of March 31, 2014 and December 31, 2013 (dollars in thousands):

			Fair Value Measurements
	Carrying Value		Level 1		Level 2		Level 3
March 31, 2014
Financial Liabilities:
Interest rate swap liability(1)	$	320	$	—	$	320	$	—
December 31, 2013
Financial Liabilities:
Interest rate swap liability(1)	$	453	$	—	$	453	$	—

(1) The Company used inputs from quoted prices for similar assets and liabilities in active markets that are directly or indirectly observable relating to the measurement of the interest rate swaps. The fair value measurement of the interest rate swaps have been classified as Level 2.

New Accounting Pronouncement

In April 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”. The amendments in the ASU change the criteria for reporting discontinued operations while enhancing disclosures in this area. The new guidance narrows the definition of discontinued operations to disposals that represent a strategic shift in operations and requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income and expenses of discontinued operations. The new guidance also requires disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The amendments in the ASU are effective for annual and interim reporting periods beginning on and after December 15, 2014. Early adoption is permitted. Adoption of this standard will currently have no effect on the Company’s financial statements.

3. Acquisition of Real Estate

In February 2013, the Company completed its acquisition of a site in Dallas, Texas for an aggregate purchase price of $21.2 million, which included transaction costs of $0.6 million that were capitalized. The Company paid cash of $10.25 million for the Dallas facility in February 2013. In connection with the transaction, the Company also obtained $10.25 million of seller-financed debt that was repaid in June 2013. Upon completion of the redevelopment, the former 700,000 square foot semiconductor plant will be converted into a data center facility on the existing campus. In accordance with ASC 805, the Company accounted for this acquisition as an asset purchase.

5. Credit Facilities and Mortgage Notes Payable

Below is a listing of our outstanding debt, excluding capital leases, as of March 31, 2014 and December 31, 2013 (in thousands):

	March 31, 2014 (Unaudited)		December 31, 2013
Unsecured Credit Facility	$	314,500	$	256,500
Richmond Credit Facility		70,000		70,000
Atlanta-Metro Equipment Loan		18,294		18,839
Total	$	402,794	$	345,339

(a) Unsecured Credit Facility – On May 1, 2013, the Company entered into an unsecured credit facility agreement with a syndicate of financial institutions in which KeyBank National Association serves as administrative agent (the “Unsecured Credit Facility”). Proceeds from the Unsecured Credit Facility were used to repay the Company’s prior secured credit facility. This unsecured credit facility has a term loan of $225 million, with a term of five years, and initially had a revolving credit facility of $350 million, with a term of four years, for an aggregate borrowing capacity of $575 million. The credit facility also provides for a $100 million accordion feature that could increase the amount of the facility up to $675 million, subject to certain conditions, including the consent of the administrative agent and obtaining necessary commitments.

The Unsecured Credit Facility requires monthly interest payments and requires the Company to comply with various quarterly covenant requirements relating to debt service coverage ratio, fixed charge ratio, leverage ratio and tangible net worth and various other operational requirements. In connection with the Unsecured Credit Facility, as of March 31, 2014, the Company had an additional $3 million letter of credit outstanding.

Amounts outstanding under the unsecured credit facility bear interest at a variable rate equal to, at our election, LIBOR or a base rate, plus a spread that will range, depending upon our leverage ratio, from 2.10% to 2.85% for LIBOR loans or 1.10% to 1.85% for base rate loans. As of March 31, 2014, the weighted average interest rate for amounts outstanding under our credit facility was 2.26%.

In February 2014, the Company expanded the capacity of its unsecured revolving credit facility by $50 million, increasing the unsecured revolving credit facility capacity to $400 million. In April 2014, the Company amended the credit facility to allow the Company to prepay the term loan with proceeds of any new unsecured debt until the outstanding balance is equal to or less than $150 million, rather than prepay the entire $225 million of the term loan as was previously required.

(b) Richmond Credit Facility – In December 2012, the Company entered into a credit facility secured by the Company’s Richmond data center (the “Richmond Credit Facility”). This credit facility had a total borrowing capacity of $80 million at December 31, 2012, which was increased to $100 million in January 2013. This credit facility also includes an accordion feature that allows the Company to increase the size of the credit facility up to $125 million and requires the Company to comply with covenants similar to the Unsecured Credit Facility. This credit facility bears interest at variable rates ranging from LIBOR plus 4.0% to LIBOR plus 4.5%. The interest rate at March 31, 2014 was LIBOR plus 4.00%, or 4.15% per annum based on the Company’s overall leverage ratio as defined in the agreement, and the loan has a stated maturity date of December 18, 2015 with an option to extend for one additional year.

(c) Atlanta-Metro Equipment Loan – On April 9, 2010, the Company entered into a $25 million loan to finance equipment related to an expansion project at the Company’s Atlanta-Metro data center (the “Atlanta-Metro Equipment Loan”). The loan originally featured monthly interest-only payments but now requires monthly interest and principal payments. The loan bears interest at 6.85%, amortizes over ten years and matures on June 1, 2020.

- 13 -

The annual remaining principal payment requirements as of March 31, 2014 per the contractual maturities and excluding extension options are as follows (in thousands):

2014	$	1,694
2015		72,397
2016		2,567
2017		92,248
2018		227,943
Thereafter		5,945
Total	$	402,794

As of March 31, 2014, the Company was in compliance with all of its covenants.

6. Interest Rate Derivative Instruments

The Company entered into interest rate cap and swap agreements with a notional amount of $150 million on February 8, 2012, which are designated as cash flow hedges for hedge accounting. In addition, an interest rate cap of an additional $50 million was in place as of December 31, 2013 with a capped LIBOR rate of 3% through December 18, 2015. For derivative instruments that are accounted for as hedges, the change in fair value for the effective portions of qualifying hedges is recorded through other comprehensive income (loss). The total unrealized gain recorded in other comprehensive income (loss) was $0.1 million and $0.1 million for the three months ended March 31, 2014 and March 31, 2013, respectively.

Interest expense related to payments on interest rate swaps for the three months ended March 31, 2014 and March 31, 2013 were $0.2 million and $0.1 million, respectively.

As of March 31, 2014 and December 31, 2013 the value of the interest rate swaps was a liability of $0.3 million and $0.5 million, respectively. These values were determined using Level 2 inputs within the valuation hierarchy.

7. Commitments and Contingencies

The Company is subject to various routine legal proceedings and other matters in the ordinary course of business. While resolution of these matters cannot be predicted with certainty, management believes, based upon information currently available, that the final outcome will not have a material adverse impact on the Company’s financial statements. The Company previously entered into a master service agreement with a third party Internet service provider. The Company was not receiving industry-standard quality of Internet and connectivity services and terminated the contract. The third party Internet service provider challenged the grounds for the Company’s termination and sued the Company in Georgia state court seeking the fees the Company owed prior to the termination plus a termination fee equal to the amount the Company would have paid had it not terminated the agreement. The Georgia state court ruled to limit damages, if any, to six months of unpaid fees. Additional claims related to a prior settlement agreement between the parties and the enforceability of an early termination clause in a separate agreement have been raised and are being litigated. The Company has established an accrual associated with this matter which is recorded as a component of accrued liabilities.

8. Partners’ Capital, Equity and Incentive Compensation Plans

The Company has the full power and authority to do all the things necessary to conduct the business of the Operating Partnership.

As of March 31, 2014, the Operating Partnership had three classes of limited partnership units outstanding: Class A units of limited partnership interest (“Class A units”), Class RS LTIP units of limited partnership interest (“Class RS units”) and Class O LTIP units of limited partnership units (“Class O Units”). The Class A Units are redeemable at any time on or after one year following the later of the beginning of the first full calendar month following the completion of the IPO or the date of initial issuance. The Company may in its sole discretion elect to assume and satisfy the redemption amount with cash or its shares. Class RS units or Class O units were issued upon grants made under the QualityTech, LP 2010 Equity Incentive Plan (the “2010 Equity Plan”). Class RS units and Class O units may be subject to vesting and are pari passu with Class A units. Vested Class RS units and Class O units are convertible into Class A units based on formulas contained in the partnership agreement of the Operating Partnership.

In connection with its IPO, the Company issued Class A common stock and Class B common stock. Class B common stock entitles the holder to 50 votes per share and was issued to enable the Company’s Chief Executive Officer to exchange 2% of his Operating Partnership units so he may have a vote proportionate to his economic interest in the Company. Also in connection with its IPO, the Company adopted the QTS Realty Trust, Inc. 2013 Equity Incentive plan (the “2013 Equity Incentive Plan”), which authorized 1.75 million shares to be issued under the plan, including options to purchase Class A common stock, restricted Class A common stock, Class O units and Class RS units.

The total intrinsic value of the awards outstanding at March 31, 2014 was $10.3 million.

In January 2014 the Company paid a dividend to common stockholders of $0.24 per common share and the Operating Partnership made a distribution to its partners of $0.24 per unit in an aggregate amount of $9.0 million. On February 13, 2014, the Company’s Board of Directors authorized payment of a regular quarterly cash dividend of $0.29 per common share, which was subsequently paid on April 8, 2014, to stockholders of record as of the close of business on March 20, 2014.

9. Related Party Transactions

The Company periodically executes transactions with entities affiliated with its Chairman and Chief Executive Officer. Such transactions include automobile, furniture and equipment purchases as well as building operating lease payments and an allocation of insurance expense and reimbursement at the related party’s cost for the use of a private aircraft service by our officers and directors.

The transactions which occurred during the three months ended March 31, 2014 and 2013 are outlined below (in thousands):

- 16 -

10. Noncontrolling Interest

Concurrently with the completion of the IPO, QTS Realty Trust, Inc. consummated a series of transactions pursuant to which the Company became the sole general partner and majority owner of QualityTech, LP, which then became its operating partnership. The previous owners of QualityTech, LP retained 21.2% ownership of the Operating Partnership.

Commencing at the beginning of the first calendar month following the first anniversary of the completion of the IPO, at the election of the owners of the noncontrolling interest, the Class A units will be redeemable for cash or, at the election of QTS Realty Trust, Inc., common stock of QTS Realty Trust, Inc. on a one-for-one basis.

11. Earnings per share

Basic income (loss) per share is calculated by dividing the net income (loss) attributable to common shares by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share adjusts basic income (loss) per share for the effects of potentially dilutive common shares.

Total	$	542,551

13. Fair Value of Financial Instruments

ASC Topic 825 requires disclosure of fair value information about financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practicable to estimate that value. In cases where quoted market prices are not available, fair values are based upon the application of discount rates to estimated future cash flows based upon market yields or by using other valuation methodologies. Considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, fair values are not necessarily indicative of the amounts the Company could realize on disposition of the financial instruments. The use of different market assumptions and/or estimation methodologies may have a material effect on estimated fair value amounts.

- 17 -

Short-term instruments: The carrying amounts of cash and cash equivalents, restricted cash approximate fair value.

Credit facilities and mortgage notes payable: The fair value of the Company’s floating rate mortgage loans was estimated using Level 2 “significant other observable inputs” such as available market information based on borrowing rates that the Company believes it could obtain with similar terms and maturities. At March 31, 2014, the fair value of the Atlanta-Metro Equipment Loan, based on current market rates, was approximately $17.6 million. The Company’s Unsecured Credit Facility and Richmond Credit Facility did not have interest rates which were materially different than current market conditions and therefore, the fair value of each of the credit facilities approximated the carrying value of each note.

Other debt instruments: The fair value of the Company’s other debt instruments (including capital leases) were estimated in the same manner as the credit facilities and mortgage notes payable above. Similarly, because each of these instruments did not have interest rates which were materially different than current market conditions and therefore, the fair value of each instrument approximated the respective carrying values.

14. Subsequent Events

On April 8, 2014, the Company paid its regular quarterly cash dividend of $0.29 per common share to stockholders of record as of the close of business on March 20, 2014.

On April 11, 2014, the Company amended the credit agreement governing its Unsecured Credit Facility to require the Company to use proceeds of any new unsecured debt of the Operating Partnership, the Company or any of their respective subsidiaries to prepay term loans under the agreement until the outstanding balance of the term loans is equal to or less than $150 million, rather than requiring prepayment in full.

In April 2014, the Company decided to reduce the number of employees, primarily located in its New Jersey market. Those positions will be relocated to the new operations center in Suwanee, GA and its corporate headquarters in Overland Park, KS. This will result in an estimated aggregate, non-recurring charge of approximately $1.5 million, of which approximately $1.3 million is expected to occur in the second quarter of 2014 and the remainder will impact third quarter 2014 results.

On May 6, 2014, the Company’s Board of Directors authorized payment of a regular quarterly cash dividend of $0.29 per common share, payable on July 8, 2014, to stockholders of record as of the close of business on June 20, 2014.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis presents the financial condition and results of operations of QTS Realty Trust, Inc. for the three months ended March 31, 2014 and our predecessor, QualityTech, LP, for the three months ended March 31, 2013. You should read the following discussion and analysis in conjunction with the accompanying consolidated financial statements and related notes contained elsewhere in this Form 10-Q.

Forward-Looking Statements

Some of the statements contained in this Form 10-Q constitute forward-looking statements within the meaning of the federal securities laws. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. In particular, statements pertaining to our capital resources, portfolio performance and results of operations contain forward-looking statements. Likewise, all of our statements regarding anticipated growth in our funds from operations and anticipated market conditions are forward-looking statements. In some cases, you can identify forward-looking statements by the use of forward-looking terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” or “potential” or the negative of these words and phrases or similar words or phrases which are predictions of or indicate future events or trends and which do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or intentions.

The forward-looking statements contained in this Form 10-Q reflect our current views about future events and are subject to numerous known and unknown risks, uncertainties, assumptions and changes in circumstances that may cause our actual results to differ significantly from those expressed in any forward-looking statement. We do not guarantee that the transactions and events described will happen as described (or that they will happen at all). The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements:

• adverse economic or real estate developments in our markets or the technology industry;

• national and local economic conditions;

• difficulties in identifying properties to acquire and completing acquisitions;

• our failure to successfully develop, redevelop and operate acquired properties;

• significant increases in construction and development costs;

• the increasingly competitive environment in which we operate;

• defaults on or non-renewal of leases by customers;

• increased interest rates and operating costs, including increased energy costs;

• financing risks, including our failure to obtain necessary outside financing;

• decreased rental rates or increased vacancy rates;

• dependence on third parties to provide Internet, telecommunications and network connectivity to our data centers;

• our failure to qualify and maintain our qualification as a REIT;

• environmental uncertainties and risks related to natural disasters;

• financial market fluctuations; and

• changes in real estate and zoning laws and increases in real property tax rates.

While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. We disclaim any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, of new information, data or methods, future events or other changes. For a further discussion of these and other factors that could cause our future results to differ materially from any forward-looking statements, see the section entitled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2013 and Item 1A. “Risk Factors” of this Form 10-Q.

Overview

We are a leading owner, developer and operator of state-of-the-art, carrier-neutral, multi-tenant data centers. Our data centers are facilities that house the network and computer equipment of multiple customers and provide access to a range of communications carriers. We have a fully integrated platform through which we own and operate our data centers and provide a broad range of IT infrastructure solutions. We refer to our spectrum of core data center products as our “3Cs,” which consists of Custom Data Center, Colocation and Cloud and Managed Services. We believe that we own and operate one of the largest portfolios of multi-tenant data centers in the United States, as measured by gross square footage, and have the capacity to more than double our leased raised floor without constructing or acquiring any new buildings.

We operate a portfolio of 10 data centers across seven states, located in some of the top U.S. data center markets plus other high-growth markets. Our data centers are highly specialized, full-service, mission-critical facilities used by our customers to house, power and cool the networking equipment and computer systems that support their most critical business processes. We believe that our data centers are best-in-class and engineered to among the highest specifications commercially available to customers, providing fully redundant, high-density power and cooling sufficient to meet the needs of major national and international companies and organizations. This is in part reflected by our operating track record of “five-nines” (99.999%) reliability and by our diverse customer base of more than 800 customers, including financial institutions, healthcare companies, government agencies, communications service providers, software companies and global Internet companies.

We are a Maryland corporation formed on May 17, 2013. On October 15, 2013, we completed our initial public offering (“IPO”) of Class A common stock, $0.01 par value per share. Our Class A common stock trades on the New York Stock Exchange under the ticker symbol “QTS.” Concurrently with the completion of the IPO, we consummated a series of transactions pursuant to which we became the sole general partner and majority owner of Quality Tech, LP, our operating partnership. We contributed the net proceeds

- 19 -

of the IPO to the operating partnership in exchange for units of limited partnership interest. As of March 31, 2014, we owned an approximate 78.8% ownership interest in the operating partnership. Substantially all of our assets are held by, and our operations are conducted through, the operating partnership.

We believe that we have operated and are organized in conformity with the requirements for qualification and taxation as a REIT commencing with our taxable year ended December 31, 2013. Our qualification as a REIT, and maintenance of such qualification, depends upon our ability to meet, on a continuing basis, various complex requirements under the Internal Revenue Code of 1986, as amended (the “Code”) relating to, among other things, the sources of our gross income, the composition and values of our assets, our distributions to our stockholders and the concentration of ownership of our equity shares.

Our Customer Base

We provide data center solutions to a diverse set of customers. Our customer base is comprised of companies of all sizes representing an array of industries, each with unique and varied business models and needs. We serve Fortune 1000 companies as well as small and medium businesses, or SMBs, including financial institutions, healthcare companies, government agencies, communications service providers, software companies and global Internet companies.

Our Custom Data Center, or C1, customers typically are large enterprises with significant IT expertise and specific IT requirements, including financial institutions, “Big Four” accounting firms and the world’s largest global Internet companies. Our Colocation, or C2, customers consist of a wide range of organizations, including major healthcare, telecommunications and software and web-based companies. Our C3 Cloud customers include both large organizations and SMBs seeking to reduce their capital expenditures and outsource their IT infrastructure on a flexible basis. Examples of current C3 Cloud customers include a global financial processing company, a U.S. government agency and an educational software provider.

As a result of our diverse customer base, customer concentration in our portfolio is limited. As of March 31, 2014, only two of our more than 800 customers individually accounted for more than 3% of our monthly recurring revenue (“MRR”) (as defined below), with the largest customer accounting for approximately 8% of our MRR. In addition, approximately 47% of our MRR was attributable to customers who use more than one of our 3Cs products.

Our Portfolio

We operate 10 data centers located in seven states, containing an aggregate of approximately 3.8 million gross square feet of space (approximately 92% of which is wholly owned by us), including approximately 1.8 million “basis-of-design” raised floor square feet, which represents the total data center raised floor potential of our existing data center facilities. This represents the maximum amount of space in our existing buildings that could be leased following full build-out, depending on the configuration that we deploy. As of March 31, 2014, this space included approximately 740,109 raised floor operating net rentable square feet, or NRSF, plus approximately 1.1 million square feet of additional raised floor in our development pipeline, of which approximately 138,000 NRSF is expected to become operational by December 31, 2014. Our facilities collectively have access to over 500 MW of gross utility power with 390 MW of available utility power. We believe such access to power gives us a competitive advantage in redeveloping data center space, since access to power is usually the most limiting and expensive component in data center redevelopment.

Key Operating Metrics

The following sets forth definitions for our key operating metrics. These metrics may differ from similar definitions used by other companies.

Monthly Recurring Revenue (“MRR”). We calculate MRR as monthly contractual revenue under signed leases as of a particular date, which includes revenue from our C1, C2 and C3 rental and cloud and managed services activities, but excludes customer recoveries, deferred set-up fees, variable related revenues, non-cash revenues and other one-time revenues. MRR does not include the impact from booked-not-billed leases as of a particular date, unless otherwise specifically noted.

Annualized Rent. We define annualized rent as MRR multiplied by 12.

Rental Churn. We define rental churn as the MRR impact from a customer completely departing our platform in a given period compared to the total MRR at the beginning of the period.

Leasable Raised Floor. We define leasable raised floor as the amount of raised floor square footage that we have leased plus the available capacity of raised floor square footage that is in a leasable format as of a particular date and according to a particular product configuration. The amount of our leasable raised floor may change even without completion of new redevelopment projects due to changes in our configuration of C1, C2 and C3 product space.

- 21 -

Percentage (%) Leased Raised Floor. We define percentage leased raised floor as the square footage that is subject to a signed lease for which billing has commenced as of a particular date compared to leasable raised floor as of that date, expressed as a percentage.

Booked-not-Billed. We define booked-not -billed as our customer leases that have been signed, but for which lease payments have not yet commenced.

Factors That May Influence Future Results of Operations and Cash Flows

Revenue. Our revenue growth will depend on our ability to maintain the historical occupancy rates of leasable raised floor, lease currently available space, lease new capacity that becomes available as a result of our development and redevelopment activities, attract new customers and continue to meet the ongoing technological requirements of our customers. As of March 31, 2014, we had in place customer leases generating revenue for approximately 92% of our leasable raised floor. Our ability to grow revenue also will be affected by our ability to maintain or increase rental, cloud and managed services rates at our properties. Future economic downturns, regional downturns or downturns in the technology industry could impair our ability to attract new customers or renew existing customers’ leases on favorable terms, or at all, and could adversely affect our customers’ ability to meet their obligations to us. Negative trends in one or more of these factors could adversely affect our revenue in future periods, which would impact our results of operations and cash flows. We also at times may elect to reclaim space from customers in a negotiated transaction where we believe that we can redevelop and/or re-lease that space at higher rates, which may cause a decrease in revenue until the space is re-leased.

Leasing Arrangements. As of March 31, 2014, 20% of our MRR came from customers which individually occupied more than 6,600 square feet of space and which had metered power. Under the metered power model, the customer pays us a fixed monthly rent amount, plus reimbursement of certain other operating costs, including actual costs of sub-metered electricity used to power its data center equipment and an estimate of costs for electricity used to power supporting infrastructure for the data center, expressed as a factor of the customer’s actual electricity usage. Fluctuations in our customers’ utilization of power and the supplier pricing of power do not significantly impact our results of operations or cash flows under the metered power model. These leases generally have a minimum term of five years. As of March 31, 2014, 80% of our MRR was leased to customers which individually occupied less than 6,600 square feet of space, many of whom are billed on a gross lease basis. Under a gross lease, the customer pays us a fixed rent on a monthly basis, and does not separately reimburse us for operating costs, including utilities, maintenance, repair, property taxes and insurance, as reimbursement for these costs is factored into MRR. However, if customers access more utility costs than their leases permit, we are able to charge these customers for overages. For leases under the gross lease model, fluctuations in our customers’ utilization of power and the prices our utility providers charge us will impact our results of operations and cash flows. Our leases on a gross lease basis generally have a term of three years or less.

Scheduled Lease Expirations. Our ability to minimize rental churn and customer downgrades at renewal and renew, lease and re-lease expiring space will impact our results of operations and cash flows. Leases representing approximately 12% and 10% of our total leased raised floor are scheduled to expire during the years ending December 31, 2014 (including all month-to-month leases) and 2015, respectively. These leases also represented approximately 25% and 21%, respectively, of our annualized rent as of March 31, 2014. At expiration, as a general matter, based on current market conditions, we expect that expiring rents will be at or below the then-current market rents.

Acquisitions, Redevelopment and Financing. Our revenue growth also will depend on our ability to acquire and redevelop and subsequently lease data center space at favorable rates. We generally fund the cost of data center acquisition and redevelopment from capital which we would expect to obtain primarily through our net cash provided by operations, credit facilities, other unsecured and secured borrowings or the issuance of additional equity. We believe that we have sufficient access to capital from our current cash and cash equivalents balance, and borrowings under our credit facilities to fund our redevelopment projects.

Operating Expenses. Our operating expenses generally consist of direct personnel costs, utilities, property and ad valorem taxes, insurance and site maintenance costs and rental expenses on our ground and building leases. In particular, our buildings require significant power to support the data center operations conducted in them. Although substantially all of our long-term leases—leases with a term greater than three years—contain reimbursements for certain operating expenses, we will not in all instances be reimbursed for all of our property operating expenses incurred. We also incur general and administrative expenses, including expenses relating to senior management, our in-house sales and marketing organization, cloud and managed services support personnel and legal, human resources, accounting and other expenses related to professional services. We also will incur additional expenses arising from being a publicly traded company, including employee equity-based compensation. Increases or decreases in our operating expenses will impact our results of operations and cash flows. We expect to incur additional operating expenses as we continue to expand.

General Leasing Activity

During the three months ended March 31, 2014, the Company entered into customer leases representing approximately $0.9 million of incremental MRR, net of downgrades (and representing approximately $10.5 million of annualized rent) at $1,195 per square foot. In addition, the Company incurred $2.9 million of leasing commissions related to new leasing activity for the three months ended March 31, 2014.

During the three months ended March 31, 2014, the Company renewed leases with a total annualized rent of $5.0 million at an average rent per square foot of $770, which was 8.9% higher than the annualized rent prior to their respective renewals. Customers that renew with adjustments to square feet are reflected in the net leasing activity discussed above. The rental churn rate for the three months ended March 31, 2014, was 1.4%.

During the three months ended March 31, 2014, the Company commenced customer leases representing approximately $1.0 million of incremental MRR (and representing approximately $12.2 million of annualized rent) at $558 per square foot.

As of March 31, 2014, our booked-not-billed MRR balance (which represents customer leases that have been executed, but for which lease payments have not commenced as of March 31, 2014) was approximately $2.5 million, or $29.9 million of annualized rent. Of this booked-not-billed balance, approximately $7.4 million of annualized rent was attributable to new customers and approximately $22.5 million of annualized rent was attributable to existing customers. Of this booked-not-billed MRR balance, leases representing approximately $15.5 million of annualized MRR are scheduled to commence in 2014, which is expected to contribute approximately $9.6 million of incremental revenue in 2014.

Revenues. Total revenues for the three months ended March 31, 2014 were $48.9 million compared to $41.5 million for the three months ended March 31, 2013. The increase of $7.4 million, or 18%, was primarily due to organic growth in our customer base. The increase of $6.9 million, or 18%, in combined rental and cloud and managed services revenue was primarily due to newly leased space as well as increases in rents from previously leased space, net of downgrades at renewal and rental churn.

In the fourth quarter of 2013, the Company reclaimed 66,000 square feet of space in our Atlanta-Metro facility. This space was substantially re-leased to an existing C1 customer, that began billing in January 2014 and will continue to ramp through the third quarter of 2014. During the three months ended March 31, 2014, we put in service 50,000 square feet of this space. The remaining 16,000 square feet of the reclaimed space is expected to be re-leased to C2 customers.

As of March 31, 2014, our data centers were 93% leased based on leasable raised floor of approximately 502,000 square feet, with an average annualized rent of $349 per leased raised floor square foot including cloud and managed services revenue, or $316 per leased raised floor square foot excluding cloud and managed services revenue. As of March 31, 2014, the average annualized rent for our C1 product, including managed services for our C1 product, was $180 per leased raised floor square foot, and the average annualized rent for our C2 product, including Cloud and managed services combined was $965 per leased raised floor square foot. As of March 31, 2013, our data centers were 87% leased based on leasable raised floor of approximately 555,000 square feet, with an average annualized rent of $338 per leased raised floor square foot including cloud and managed services revenue, or $300 per leased raised floor square foot excluding cloud and managed services revenue.

Higher recoveries from customers for the three months ended March 31, 2014 compared to the three months ended March 31, 2013 were primarily due to increased utility costs at our Atlanta-Metro, Richmond and Sacramento data centers, which contributed $0.3 million, $0.2 million and $0.2 million to the increase, respectively. The $0.3 million decrease in other revenue for the three months ended March 31, 2014 compared to the three months ended March 31, 2013 was primarily due to lower sales of scrap metals and other unused materials.

Property Operating Costs. Property operating costs for the three months ended March 31, 2014 were $16.2 million compared to property operating costs of $14.4 million for the three months ended March 31, 2013, an increase of $1.8 million, or 13%. The breakdown of our property operating costs is summarized in the table below (in thousands):

	Three Months Ended March 31, (unaudited)
	The Company		Historical Predecessor
	2014		2013		$ Change			% Change
Property operating costs:
Direct payroll	$	2,941	$	3,013	$	(72	)		-2	%
Rent		1,219		1,104		115			10	%
Repairs and maintenance		1,152		1,179		(27	)		-2	%
Utilities		6,632		5,547		1,085			20	%
Management fee allocation		1,951		1,651		300			18	%
Other		2,328		1,914		414			22	%
Total property operating costs	$	16,223	$	14,408	$	1,815			13	%

The increase in utilities expense was primarily attributable to higher utility costs associated with the ongoing expansions of our Atlanta-Metro, Atlanta-Suwanee, Santa Clara and Richmond data centers, which resulted in an aggregate increase of $1.1 million in utilities expense. The management fee allocation is based on 4% of cash rental revenues for each facility and reflects an allocation of internal charges to cover back-office and service-related costs associated with the day-to-day operations of our data center facilities, with a corresponding offset to general and administrative expenses. The increase in other operating expenses of $0.4 million was primarily due to increased outsourcing of our facility security personnel, which contributed to the decrease in direct payroll costs.

Real Estate Taxes and Insurance. Real estate taxes and insurance for the three months ended March 31, 2014 were $1.2 million compared to $1.1 million for the three months ended March 31, 2013. The increase of $0.1 million, or 9%, was primarily attributable to the expansion of our Richmond data center.

Depreciation and Amortization. Depreciation and amortization for the three months ended March 31, 2014 was $13.2 million compared to $10.8 million for the three months ended March 31, 2013. The increase of $2.4 million, or 22%, was primarily due to additional depreciation of $1.7 million associated with expansion of our Atlanta-Metro, Atlanta-Suwanee and Richmond data centers, and higher amortization expense related to a higher level of leasing commissions of $0.7 million.

General and Administrative Expenses. General and administrative expenses were $10.8 million for the three months ended March 31, 2014 compared to general and administrative expenses of $9.6 million for the three months ended March 31, 2013, an increase of $1.2 million, or 12%. Approximately $2.8 million of the total general and administrative expenses for the three months ended March 31, 2014 resulted from sales and marketing expenses, compared to $2.3 million for the three months ended March 31, 2013. The increase in general and administrative expenses was primarily attributable to higher professional fees of $0.5 million, higher personnel costs of $0.3 million, higher travel costs of $0.2 million and higher advertising and marketing expenses of $0.2 million. An increase in personnel costs of $0.3 million is primarily a result of expanding our senior management team and our sales and marketing organization in conjunction with the expansion of our data center facilities and formation of our enterprise, government and customer retention teams and development of our Cloud and Managed Services products. Total equity-based compensation expense was $0.9 million and $0.4 million for the three months ended March 31, 2014 and 2013, respectively. Our general and administrative expenses represented 22.0% of total revenues for the three months ended March 31, 2014 compared to 23.1% for the three months ended March 31, 2013.

Transaction Costs. For the three months ended March 31, 2014 we incurred $0.1 million in costs related to the examination of proposed acquisitions. Acquisition-related costs are expensed in the periods in which the costs are incurred and the services are received.

Interest Expense. Interest expense for the three months ended March 31, 2014 was $2.1 million compared to $6.6 million for the three months ended March 31, 2013. The decrease of $4.5 million, or 68%, was due to a decrease in our average debt balance of $158.3 million as a result of our IPO in October 2013, a reduction in the weighted average interest rate on our borrowings and higher capitalized interest during the period. During the second quarter of 2013, we replaced our $440 million secured credit facility with a $575 million unsecured credit facility. In addition, the interest rate spread over LIBOR on the unsecured credit facility was 165 basis points lower than the secured credit facility. The average debt balance for the three months ended March 31, 2014 was $389.3 million, with a weighted average interest rate, including the effect of interest rate swaps and amortization of deferred financing costs, of 3.75%. This compared to an average debt balance of $547.5 million for the three months ended March 31, 2013, with a weighted average interest rate, including the effect of interest rate swaps and amortization of deferred financing costs, of 5.49%. Interest capitalized in connection with our redevelopment activities during the three months ended March 31, 2014 and March 31, 2013 was $1.6 million and $1.0 million, respectively.

Other Expense/Income. Other expense for the three months ended March 31, 2013 was $1.1 million. This was due to a write-off of unamortized deferred financing costs in the first quarter of 2013 related to an asset securitization which we did not pursue.

Net Income (Loss). A summary of the components of the increase in net income of $7.4 million for the three months ended March 31, 2014 as compared to the three months ended March 31, 2013 is as follows:

	$ Change
Increase in revenues, net of property operating costs, real estate taxes and insurance	$	5.5
Increase in general and administrative expense		(1.2	)
Increase in depreciation and amortization		(2.4	)
Increase in transaction costs		(0.1	)
Decrease in interest expense net of interest income		4.5
Decrease in other expense		1.1

Non-GAAP Financial Measures

We consider the following non-GAAP financial measures to be useful to investors as key supplemental measures of our performance: (1) FFO; (2) Operating FFO; (3) MRR; (4) NOI; (5) EBITDA; and (6) Adjusted EBITDA. These non-GAAP financial measures should be considered along with, but not as alternatives to, net income or loss and cash flows from operating activities as a measure of our operating performance and liquidity. FFO, Operating FFO, MRR, NOI, EBITDA and Adjusted EBITDA, as calculated by us, may not be comparable to FFO, Operating FFO, MRR, NOI, EBITDA and Adjusted EBITDA as reported by other companies that do not use the same definition or implementation guidelines or interpret the standards differently from us.

FFO and Operating FFO

We consider funds from operations, or FFO, to be a supplemental measure of our performance which should be considered along with, but not as an alternative to, net income (loss) and cash provided by operating activities as a measure of operating performance and liquidity. We calculate FFO in accordance with the standards established by the National Association of Real Estate Investment Trusts (“NAREIT”). FFO represents net income (loss) (computed in accordance with GAAP), adjusted to exclude gains (or losses) from sales of property, real estate related depreciation and amortization and similar adjustments for unconsolidated partnerships and joint ventures. Our management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs.

Due to the volatility and nature of certain significant charges and gains recorded in our operating results that management believes are not reflective of our core operating performance and liquidity, management computes an adjusted measure of FFO, which we refer to as Operating FFO. We generally calculate Operating FFO as FFO excluding certain non-recurring and primarily non-cash charges and gains and losses that management believes are not indicative of the results of our operating real estate portfolio. We believe that Operating FFO provides investors with another financial measure that may facilitate comparisons of operating performance and liquidity between periods and, to the extent they calculate Operating FFO on a comparable basis, between REITs.

We offer these measures because we recognize that FFO and Operating FFO will be used by investors as a basis to compare our operating performance and liquidity with that of other REITs. However, because FFO and Operating FFO exclude real estate 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 capitalized leasing commissions necessary to maintain the operating performance of our

- 26 -

properties, all of which have real economic effect and could materially impact our financial condition, cash flows and results of operations, the utility of FFO and Operating FFO as measures of our operating performance and liquidity is limited. Our calculation of FFO may not be comparable to measures calculated by other companies who do not use the NAREIT definition of FFO or do not calculate FFO in accordance with NAREIT guidance. In addition, our calculations of FFO and Operating FFO are not necessarily comparable to FFO and Operating FFO as calculated by other REITs that do not use the same definition or implementation guidelines or interpret the standards differently from us. FFO and Operating FFO are non-GAAP measures and should not be considered a measure of our results of operations or liquidity or as a substitute for, or an alternative to, net income (loss), cash provided by operating activities or any other performance measure determined in accordance with GAAP, nor is it indicative of funds available to fund our cash needs, including our ability to make distributions to our stockholders.

Monthly Recurring Revenue (MRR) and Recognized MRR

We calculate MRR as monthly contractual revenue under signed leases as of a particular date, which includes revenue from our C1, C2 and C3 rental and cloud and managed services activities, but excludes customer recoveries, deferred set-up fees, variable related revenues, non-cash revenues and other one-time revenues. MRR does not include the impact from booked-not-billed leases as of a particular date, unless otherwise specifically noted.

Separately, we calculate recognized MRR as the recurring revenue recognized during a given period, which includes revenue from our C1, C2 and C3 rental and cloud and managed services activities, but excludes customer recoveries, deferred set-up fees, variable related revenues, non-cash revenues and other one-time revenues.

Management uses MRR and recognized MRR as supplemental performance measures because they provide useful measures of increases in contractual revenue from our customer leases. MRR and recognized MRR should not be viewed by investors as alternatives to actual monthly revenue, as determined in accordance with GAAP. Other companies may not calculate MRR or recognized MRR in the same manner. Accordingly, our MRR and recognized MRR may not be comparable to other companies’ MRR and recognized MRR. MRR and recognized MRR should be considered only as supplements to total revenues as a measure of our performance. MRR and recognized MRR should not be used as measures of our results of operations or liquidity, nor is it indicative of funds available to meet our cash needs, including our ability to make distributions to our stockholders.

Net Operating Income (NOI)

We calculate net operating income (“NOI”), as net income (loss), excluding interest expense, interest income, tax expense of taxable REIT subsidiaries, depreciation and amortization, write off of unamortized deferred financing costs, gain on extinguishment of debt, transaction costs, gain on legal settlement, gain (loss) on sale of real estate, restructuring charge and general and administrative expenses. We allocate a management fee charge of 4% of cash rental revenues as a property operating cost and a corresponding reduction to general and administrative expense to cover the day-to-day administrative costs to operate our data centers. The management fee charge of 4% is reflected as a reduction to net operating income.

Management uses NOI as a supplemental performance measure because it provides a useful measure of the operating results from our customer leases. In addition, we believe it is useful to investors in evaluating and comparing the operating performance of our properties and to compute the fair value of our properties. Our NOI may not be comparable to other REITs’ NOI as other REITs may not calculate NOI in the same manner. NOI should be considered only as a supplement to net income as a measure of our performance and should not be used as a measure of our results of operations or liquidity or as an indication of funds available to meet our cash needs, including our ability to make distributions to our stockholders. NOI is a measure of the operating performance of our properties and not of our performance as a whole. NOI is therefore not a substitute for net income as computed in accordance with GAAP.

Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) and Adjusted EBITDA

We calculate EBITDA as net income (loss) adjusted to exclude interest expense and interest income, provision for income taxes (including income taxes applicable to sale of assets) and depreciation and amortization. Management believes that EBITDA is useful to investors in evaluating and facilitating comparisons of our operating performance between periods and between REITs by removing the impact of our capital structure (primarily interest expense) and asset base charges (primarily depreciation and amortization) from our operating results.

In addition to EBITDA, we calculate an adjusted measure of EBITDA, which we refer to as Adjusted EBITDA, as EBITDA excluding unamortized deferred financing costs, gains on extinguishment of debt, transaction costs, equity-based compensation expense, restructuring charge, gain (loss) on legal settlement and gain on sale of real estate. We believe that Adjusted EBITDA provides investors with another financial measure that can facilitate comparisons of operating performance between periods and between REITs.

Management uses EBITDA and Adjusted EBITDA as supplemental performance measures as they provide useful measures of assessing our operating results. Other companies may not calculate EBITDA or Adjusted EBITDA in the same manner. Accordingly, our EBITDA and Adjusted EBITDA may not be comparable to others. EBITDA and Adjusted EBITDA should be considered only as supplements to net income (loss) as measures of our performance and should not be used as substitutes for net income (loss), as measures of our results of operations or liquidity or as indications of funds available to meet our cash needs, including our ability to make distributions to our stockholders.

Liquidity and Capital Resources

Short-Term Liquidity

Our short-term liquidity needs include funding capital expenditures for the redevelopment of data center space through December 31, 2014 (a significant portion of which is discretionary), meeting debt service and debt maturity obligations, funding distributions to our stockholders and unit holders, utility costs, site maintenance costs, real estate and personal property taxes, insurance, rental expenses, general and administrative expenses and certain recurring and non-recurring capital expenditures.

For the period April 1, 2014 through December 31, 2014, we expect that we will incur between $90 million and $140 million in capital expenditures in connection with the redevelopment of our data center facilities. We expect to spend between $80 million and $120 million of capital expenditures on redevelopment, and the remainder on recurring capital expenditures and capitalized overhead costs (including capitalized interest, commissions, payroll and other similar costs), personal property and other less material capital projects. We expect to fund these costs using operating cash flows and draws on our credit facilities which were partially paid down with the net proceeds of the initial public offering. A significant portion of these expenditures are discretionary in nature and we may ultimately determine not to make these expenditures or the timing of such expenditures may vary. We continue to evaluate acquisition opportunities, but none are considered probable at this time and therefore the related expenditures are not currently included in these future estimates.

We expect to meet our short-term liquidity needs through operating cash flow, cash and cash equivalents and borrowings under our credit facilities.

Our cash paid for capital expenditures for the three months ended March 31, 2014 and 2013 are summarized in the table below (in thousands):

Capitalized interest, commissions and other overhead costs		5,838		5,615
Total capital expenditures	$	59,165	$	35,647

Long-Term Liquidity

Our long-term liquidity needs primarily consist of funds for property acquisitions, scheduled debt maturities and recurring and non-recurring capital expenditures. We may also pursue additional redevelopment of our Atlanta-Metro, Dallas, and Richmond data centers and future redevelopment of other space in our portfolio. The redevelopment of this space, including timing, is at our discretion and will depend on a number of factors, including availability of capital and our estimate of the demand for data center space in the applicable market. We expect to meet our long-term liquidity needs with net cash provided by operations, incurrence of additional long-term indebtedness, borrowings under our credit facilities and issuance of additional equity or debt securities, subject to prevailing market conditions, as discussed below.

Cash

As of March 31, 2014, we had $7.9 million of unrestricted cash and cash equivalents.

On January 7, 2014, we paid our first and prorated dividend to our stockholders in the amount of $7.0 million. In addition, on January 7, 2014, we made a distribution to the holders of Class A units of limited partnership of our operating partnership in an aggregate amount of approximately $2.0 million in connection with the quarterly dividend on our common stock.

On April 8, 2014, the Company paid its regular quarterly cash dividend of $0.29 per common share to stockholders of record as of the close of business on March 20, 2014.

Indebtedness

As of March 31, 2014, we had approximately $405.5 million of indebtedness, including capital lease obligations.

Unsecured Credit Facility. In May 2013, we entered into a $575 million unsecured credit facility comprised of a five-year $225 million term loan and a four-year $350 million revolving credit facility with a one year extension, subject to satisfaction of certain conditions. In February 2014, the Company expanded the capacity of its unsecured credit facility by $50 million, increasing the total unsecured revolving credit facility capacity to $400 million. The total credit facility may be increased to $675 million subject to certain conditions set forth in the credit agreement, including the consent of the administrative agent and obtaining necessary commitments, either through an increase to the term loan or revolving credit facility, or a combination of both. Amounts outstanding under the unsecured credit facility bear interest at a variable rate equal to, at our election, LIBOR or a base rate, plus a spread that will range, depending upon our leverage ratio, from 2.10% to 2.85% for LIBOR loans or 1.10% to 1.85% for base rate loans. As of March 31, 2014, the interest rate for amounts outstanding under our credit facility was 2.26%. The unsecured credit facility includes certain financial covenants, including a leverage ratio of total indebtedness to gross asset value not in excess of 55%. The interest rate applied to the outstanding balance of the unsecured credit facility decreases incrementally for every 5% below the maximum leverage ratio. The availability under the revolving credit facility is the lesser of (i) $400 million, (ii) 55% of unencumbered asset pool capitalized value, (iii) the amount resulting in an unencumbered asset pool debt service ratio of 1.75 to 1.00, as defined, or (iv) the amount resulting in an unencumbered asset pool debt yield of 15%, less, in the case of (ii), (iii) and (iv), unsecured debt as defined in the revolving credit facility. The availability of funds under our unsecured credit facility depends on compliance with our covenants. As of March 31, 2014, we had outstanding $314.5 million of indebtedness out of a total of $625 million of available capacity under our revolving credit facility.

- 31 -

Richmond Secured Credit Facility. In December 2012, we entered into a $100 million credit facility secured by our Richmond data center. This credit facility has an accordion feature that allows us to increase the capacity up to $125 million subject to certain conditions set forth in the credit agreement, including the consent of the administrative agent and obtaining necessary commitments. This credit facility has a stated maturity date of December 18, 2015 with our option to extend, subject to satisfaction of certain conditions, for one additional year. This facility carries variable interest at rates ranging from LIBOR plus 4.0% to LIBOR plus 4.5% (for which the rate as of March 31, 2014 was LIBOR plus 4.00%, or 4.16% per annum), based on our overall leverage ratio as defined in the credit facility. This credit facility includes certain financial covenants, including a leverage ratio of total indebtedness to gross asset value not in excess of 55%. The interest rate applied to the outstanding balance of the credit facility decreases incrementally for every 5% below the maximum leverage ratio. As of March 31, 2014, the interest rate for amounts outstanding under the Richmond secured credit facility was 4.16%. The availability under this credit facility is the lower of (i) 55% of mortgaged property appraised value, (ii) the amount resulting in a borrowing base debt service ratio of 1.6 to 1.0 or (iii) the amount resulting in a borrower’s debt yield of 14.5%, in each case as defined in the credit facility. The availability of funds under our Richmond credit facility depends on compliance with our covenants. The proceeds from our Richmond credit facility may be used solely to finance the development of the Richmond property into a data center and to repay indebtedness under our unsecured credit facility described above. As of March 31, 2014, we had outstanding $70 million of indebtedness out of a total of $100 million of available capacity under our Richmond credit facility.

Atlanta-Metro Equipment Loan. In April 2010, we entered into a $25 million loan to finance equipment related to an expansion project at our Atlanta-Metro data center. The loan requires monthly interest and principal payments. The loan bears interest at 6.85% per annum, amortizes over ten years and matures on June 1, 2020.

Contingencies

We are subject to various routine legal proceedings and other matters in the ordinary course of business. While resolution of these matters cannot be predicted with certainty, management believes, based upon information currently available, that the final outcome of these proceedings will not have a material adverse effect on our financial condition, liquidity or results of operations.

Contractual Obligations

The following table summarizes our contractual obligations as of March 31, 2014, including the future non-cancellable minimum rental payments required under operating leases and the maturities and scheduled principal repayments of indebtedness and other agreements (in thousands):

Contractual interest payments on our credit facilities, mortgages, capital leases and other financing arrangements through the scheduled maturity date, assuming no prepayment of debt, are shown below. Interest payments were estimated based on the principal amount of debt outstanding and the applicable interest rate as of March 31, 2014 (in thousands):

	$	12,134	$	11,766	$	8,717	$	5,184	$	1,453	$	382	$	39,636

Off-Balance Sheet Arrangements

We utilize derivatives to manage our interest rate exposure. Our interest rate swaps are designated as a cash flow hedge of future interest payments. During February 2012, we entered into two interest rate swaps with an aggregate notional amount of $150 million which qualified for hedge accounting treatment. We perform assessments of hedging effectiveness, and any ineffectiveness is recorded in interest expense. There was no ineffectiveness for the periods ended March 31, 2014 or 2013.

Operating activities	$	13,934		$	9,617
Investing activities		(59,165	)		(48,571	)
Financing activities		47,949			32,152

Three Months Ended March 31, 2014 Compared to Three Months Ended March 31, 2013

Cash flow provided by operating activities was $13.9 million for the three months ended March 31, 2014, compared to $9.6 million for the three months ended March 31, 2013. The increased cash flow provided by operating activities of $4.3 million was primarily due to an increase in cash operating income of $9.8 million, partially offset by a decrease in cash flow associated with net changes in working capital of $5.5 million primarily relating to changes in accounts payable, accrued liabilities, accrued interest on member advances, restricted cash and rent and other receivables.

Cash flow used for investing activities increased by $10.6 million to $59.2 million for the three months ended March 31, 2014, compared to $48.6 million for the three months ended March 31, 2013. The increase was primarily due to higher cash paid for capital expenditures primarily related to redevelopment of our Dallas, Atlanta-Metro and Richmond data centers of $23.5 million, partially offset by lower net cash outflow for the acquisitions of $10.9 million and lower restricted cash of $2.0 million. These expenditures include capitalized soft costs such as interest, payroll and other costs to redevelop properties, which were, in the aggregate, $3.8 million and $2.7 million for the three months ended March 31, 2014 and 2013, respectively.

Cash flow provided by financing activities was $47.9 million for the three months ended March 31, 2014, compared to $32.2 million for the three months ended March 31, 2013. The increase was primarily due to higher net borrowings of $24.5 million under our unsecured credit facility in order to redevelop our data centers, partially offset by the payment of cash dividends to common stockholders of $7.0 million and the distribution to the unit holders of the Operating Partnership of $2.0 million.

Critical Accounting Policies

The Company applies those accounting policies that management believes best reflect the underlying business and economic events, consistent with accounting principles generally accepted in the United States. Inherent in such policies are certain key assumptions and estimates made by management. Management periodically updates its estimates used in the preparation of the consolidated financial statements based on its latest assessment of the current and projected business and general economic environment. Information regarding the Company’s Critical Accounting Policies and Estimates is included in Item 7 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.

Inflation

Substantially all of our long-term leases—leases with a term greater than three years—contain rent increases and reimbursement for certain operating costs. As a result, we believe that we are largely insulated from the effects of inflation over periods greater than three years. Leases with terms of three years or less will be replaced or renegotiated within three years and should adjust to reflect changed conditions, also mitigating the effects of inflation. Moreover, to the extent that there are material increases in utility costs, we generally reserve the right to renegotiate the rate. However, any increases in the costs of redevelopment of our properties will generally result in a higher cost of the property, which will result in increased cash requirements to redevelop our properties and increased depreciation and amortization expense in future periods, and, in some circumstances, we may not be able to directly pass along the increase in these redevelopment costs to our customers in the form of higher rental rates.

Distribution Policy

To satisfy the requirements to qualify as a REIT, and to avoid paying tax on our income, we intend to continue to make regular quarterly distributions of all, or substantially all, of our REIT taxable income (excluding net capital gains) to our stockholders.

- 33 -

All distributions will be made at the discretion of our board of directors and will depend on our historical and projected results of operations, liquidity and financial condition, our REIT qualification, our debt service requirements, operating expenses and capital expenditures, prohibitions and other restrictions under financing arrangements and applicable law and other factors as our board of directors may deem relevant from time to time. We anticipate that our estimated cash available for distribution will exceed the annual distribution requirements applicable to REITs and the amount necessary to avoid the payment of tax on undistributed income. However, under some circumstances, we may be required to make distributions in excess of cash available for distribution in order to meet these distribution requirements and we may need to borrow funds to make certain distributions. If we borrow to fund distributions, our future interest costs would increase, thereby reducing our earnings and cash available for distribution from what they otherwise would have been.

Our operating partnership also includes certain partners that are subject to a taxable income allocation, however, not entitled to receive recurring distributions. The partnership agreement does stipulate however, to the extent that taxable income is allocated to these partners that the partnership will make a distribution to these partners equal to the lesser of the actual per unit distributions made to Class A partners or an estimated amount to cover federal, state and local taxes on the allocated taxable income. No such distributions were made to these partners for the three months ended March 31, 2014 or 2013.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Our future income, cash flows and fair values relevant to financial instruments are dependent upon prevailing market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. The primary market risk to which we believe we are exposed is interest rate risk. Many factors, including governmental monetary and tax policies, domestic and international economic and political considerations and other factors that are beyond our control, contribute to interest rate risk.

As of March 31, 2014, we had outstanding $384.5 million of consolidated indebtedness that bore interest at variable rates, of which $150 million was hedged utilizing interest rate swaps that have a fixed LIBOR rate of 0.5825% and expire in September 2014. An interest rate cap of an additional $50 million was in place as of March 31, 2014 with a capped LIBOR rate of 3% through December 18, 2015.

We monitor our market risk exposures using a sensitivity analysis. Our sensitivity analysis estimates the exposure to market risk sensitive instruments assuming a hypothetical 1% change in year-end interest rates. LIBOR rates are not currently within 1% of our interest rate caps, therefore a 1% increase in interest rates would increase the interest expense on the $184.5 million of variable indebtedness outstanding as of March 31, 2014 that is not hedged by approximately $1.8 million annually. Conversely, a decrease in the LIBOR rate to 0% would decrease the interest expense on this $184.5 million of variable indebtedness outstanding by approximately $0.3 million annually based on the one month LIBOR rate of approximately 0.2% as of March 31, 2014.

The above analyses do not consider the effect of any change in overall economic activity that could impact interest rates or expected changes associated with future indebtedness. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.

ITEM 4. Controls and Procedures

Disclosure Controls and Procedures

Based on an evaluation of disclosure controls and procedures for the period ended March 31, 2014, conducted by the Company’s management, with the participation of the Chief Executive Officer and Chief Financial Officer, the Chief Executive Officer and Chief Financial Officer concluded that its disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the Company’s management (including the Chief Executive Officer and Chief Financial Officer) to allow timely decisions regarding required disclosure, and is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2014, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation – The accompanying financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included.

The Interim Condensed Consolidated Statement of Operations and Comprehensive Income and the Statement of Cash Flows of the Company for the three months ended March 31, 2014 and the Balance Sheets as of March 31, 2014 and December 31, 2013 present the accounts of QTS Realty Trust, Inc. and its majority owned subsidiaries. The Interim Condensed Consolidated Statement of Operations and Comprehensive Income and the Statement of Cash Flows for the three months ended March 31, 2013 present the accounts of QualityTech, LP and its majority owned subsidiaries (the “Historical Predecessor”).

Use of Estimates – The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of fixed assets, allowances for doubtful accounts and deferred tax assets and the valuation of derivatives, real estate assets, acquired intangible assets and certain accruals.

Principles of Consolidation – The consolidated financial statements include the accounts of QTS Realty Trust, Inc. and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the financial statements.

Real Estate Assets – Real estate assets are reported at cost. All capital improvements for the income-producing properties that extend their useful lives are capitalized to individual property improvements and depreciated over their estimated useful lives. Depreciation is generally provided on a straight-line basis over 40 years from the date the property was placed in service. Property improvements are depreciated on a straight-line basis over the life of the respective improvement ranging from 20 to 40 years from the date the components were placed in service. Leasehold improvements are depreciated over the lesser of 20 years or through the end of the respective life of the lease. Repairs and maintenance costs are expensed as incurred. The aggregate depreciation charged to operations was $10.2 million and $8.5 million for the three months ended March 31, 2014 and 2013, respectively. The Company capitalizes certain development costs, including internal costs incurred in connection with development. The capitalization of costs during the construction period (including interest and related loan fees, property taxes and other direct and indirect costs) begins when development efforts commence and ends when the asset is ready for its intended use. Capitalization of such costs, excluding interest, aggregated to $2.2 million and $1.7 million for the three months ended March 31, 2014 and 2013, respectively. Interest is capitalized during the period of development by first applying the Company’s actual borrowing rate on the related asset and second, to the extent necessary, by applying the Company’s weighted average effective borrowing rate to the actual development and other costs expended during the construction period. Interest is capitalized until the property is ready for its intended use. Interest costs capitalized totaled $1.6 million and $1.0 million for the three months ended March 31, 2014 and 2013, respectively.

Acquisition of Real Estate – Acquisitions of real estate are either accounted for as asset acquisitions or business combinations depending on facts and circumstances. Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired in accordance to the accounting requirements of ASC 805, Business Combinations, which requires the recording of net assets of acquired businesses at fair value. The fair value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and improvements, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, value of in-place leases and value of customer relationships.

In developing estimates of fair value of acquired assets and assumed liabilities, management analyzed a variety of factors including market data, estimated future cash flows of the acquired operations, industry growth rates, current replacement cost for fixed assets and market rate assumptions for contractual obligations. Such a valuation requires management to make significant estimates and assumptions, particularly with respect to the intangible assets.

Intangible assets and liabilities include in-place leases and customer relationships.

Acquired in-place leases are amortized as amortization expense on a straight-line basis over the remaining life of the underlying leases. Amortization of acquired in place lease costs, including write-offs for terminated leases totaled $0.6 million and $0.6 million for the three months ended March 31, 2014 and 2013, respectively.

Acquired customer relationships are amortized as amortization expense on a straight-line basis over the expected life of the customer relationship. Amortization of acquired customer relationships totaled $0.3 million and $0.4 million for the three months ended March 31, 2014 and 2013, respectively.

Impairment of Long-Lived and Intangible Assets – The Company reviews its long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Recoverability of assets to be held and used is generally measured by comparison of the carrying amount to the future net cash flows, undiscounted and without interest, expected to be generated by the asset group. If the net carrying value of the asset exceeds the value of the undiscounted cash flows, the fair value of the asset is assessed and may be considered impaired. An impairment loss is recognized based on the excess of the carrying amount of the impaired asset over its fair value. No impairment losses were recorded for the three months ended March 31, 2014 and 2013, respectively.

Cash and Cash Equivalents – The Company considers all demand deposits and money market accounts purchased with a maturity date of three months or less at the date of purchase to be cash equivalents. The Company’s account balances at one or more institutions periodically exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is concentration of credit risk related to amounts on deposit in excess of FDIC coverage. The Company mitigates this risk by depositing a majority of its funds with several major financial institutions. The Company also has not experienced any losses and, therefore, does not believe that the risk is significant.

Deferred Costs – Deferred costs, net, on the Company’s balance sheets include both financing costs and leasing costs.

Deferred financing costs represent fees and other costs incurred in connection with obtaining debt and are amortized over the term of the loan and are included in interest expense. Amortization of the deferred financing costs was $0.6 million and $0.9 million for the three months ended March 31, 2014 and 2013, respectively. In addition, during the three months ended March 31, 2013, the Company wrote off unamortized financing costs of $1.1 million in connection with an asset securitization which the Company did not pursue due to the expansion of the credit facility. Deferred financing costs, net of accumulated amortization are as follows:

	March 31,
	2014			December 31,
(dollars in thousands)	(unaudited)			2013
Deferred financing costs	$	9,526		$	9,159
Accumulated amortization		(2,450	)		(1,867	)
Deferred financing costs, net	$	7,076		$	7,292

Deferred leasing costs consist of external fees and internal costs incurred in the successful negotiations of leases and 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. Amortization of deferred leasing costs totaled $1.3 million and $1.0 million for the three months ended March 31, 2014 and 2013, respectively. Deferred leasing costs, net of accumulated amortization are as follows:

	March 31,
	2014			December 31,
(dollars in thousands)	(unaudited)			2013
Deferred leasing costs	$	19,282		$	17,374
Accumulated amortization		(7,201	)		(5,516	)
Deferred leasing costs, net	$	12,081		$	11,858

Advance Rents and Security Deposits – Advance rents, typically prepayment of the following month’s rent, consist of payments received from customers prior to the time they are earned and are recognized as revenue in subsequent periods when earned. Security deposits are collected from customers at the lease origination and are generally refunded to customers upon lease expiration.

Deferred Income – Deferred income generally results from non-refundable charges paid by the customer at lease inception to prepare their space for occupancy. The Company records this initial payment, commonly referred to as set-up fees, as a deferred income liability which amortizes into rental revenue over the term of the related lease on a straight-line basis. Deferred income was $8.1 million and $7.9 million as of March 31, 2014 and December 31, 2013, respectively. Additionally, $1.2 million and $1.1 million of deferred income was amortized into revenue for the three months ended March 31, 2014 and 2013, respectively.

Interest Rate Derivative Instruments – The Company utilizes derivatives to manage its interest rate exposure. During February 2012, the Company entered into interest rate swaps with a notional amount of $150 million which are cash flow hedges and qualify for hedge accounting. For these hedges, the effective portion of the change in fair value is recognized through other comprehensive income or loss. Amounts are reclassified out of other comprehensive income (loss) as the hedged item is recognized in earnings, either for ineffectiveness or for amounts paid relating to the hedge. As there was no ineffectiveness recorded in the periods presented, the Company has reflected the change in the fair value of the instrument in other comprehensive income (loss). For the ineffective portions of qualifying hedges, the change in fair value is recorded through interest expense in the respective period.

Equity-based Compensation –All equity-based compensation is measured at fair value on the grant date or date of modification, as applicable, and recognized in earnings over the requisite service period. Depending upon the settlement terms of the awards, all or a portion of the fair value of equity-based awards may be presented as a liability or as equity in the consolidated balance sheets. Equity-based compensation costs are measured based upon their estimated fair value on the date of grant or modification. Equity-based compensation expense net of forfeited and repurchased awards acquired of $0.9 million and $0.4 million was recorded for the three months ended March 31, 2014 and 2013, respectively.

Rental Revenue – The Company, as a lessor, has retained substantially all of the risks and benefits of ownership and accounts for its leases as operating leases. For lease agreements that provide for scheduled 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 has been provided to the customer. The amount of the straight-line rent receivable on the balance sheets included in rents and other receivables, net was $3.1 million and $2.9 million as of March 31, 2014 and December 31, 2013, respectively. Rental revenue also includes amortization of set-up fees which are amortized over the term of the respective lease as discussed above.

Allowance for Uncollectible Accounts Receivable – Rents receivable are recognized when due and are carried at cost, less an allowance for doubtful accounts. The Company records a provision for losses on rents receivable equal to the estimated uncollectible accounts, which is based on management’s historical experience and a review of the current status of the Company’s receivables. As necessary, the Company also establishes an appropriate allowance for doubtful accounts for receivables arising from the straight-lining of rents. The aggregate allowance for doubtful accounts was $1.3 million and $0.9 million as of March 31, 2014 and December 31, 2013, respectively.

Capital Lease – The Company evaluates leased real estate to determine whether the lease should be classified as a capital or operating lease in accordance with U.S GAAP.

The Company periodically enters into capital leases for certain equipment. The outstanding liabilities for the capital leases were $2.7 million and $2.5 million as of March 31, 2014 and December 31, 2013, respectively. Depreciation related to the associated assets is included in depreciation and amortization expense in the Statements of Operations and Comprehensive Income (Loss).

Recoveries from Customers – Certain customer leases contain provisions under which the customers reimburse the Company for a portion of the property’s real estate taxes, insurance and other operating expenses, which include certain power and cooling-related charges. The reimbursements are included in revenue as recoveries from customers in the Statements of Operations and Comprehensive Income (Loss) in the period the applicable expenditures are incurred. Certain customer leases are structured to provide a fixed monthly billing amount that includes an estimate of various operating expenses, with all revenue from such leases included in rental revenues.

Cloud and Managed Services Revenue – The Company may provide both its cloud product and use of its managed services to its customers on an individual or combined basis. Service fee revenue is recognized as the revenue is earned, which generally coincides with the services being provided.

Segment Information – The Company manages its business as one operating segment and thus one reportable segment consisting of a portfolio of investments in data centers located in the United States.

Customer Concentrations – As of March 31, 2014, two of the Company’s customers represented 8.0% and 5.5%, respectively, of its total monthly rental revenue. No other customers exceeded 5% of total monthly rental revenue.

As of March 31, 2014, six of the Company’s customers exceeded 5% of total accounts receivable. In aggregate, these six customers accounted for 39.5% of total accounts receivable. None of these six customers individually exceeded 10% of total accounts receivable.

Income Taxes – The Company is obligated to comply with Internal Revenue Service real estate investment trust (“IRS REIT”) tax regulations in accordance with the unit holders’ agreement. In order to comply with this obligation, the Company elected for one of its existing subsidiaries to be taxed as a taxable REIT subsidiary under the IRS REIT tax regulations. The taxable REIT subsidiary is allocated income and expense based on IRS REIT tax regulations.

For the taxable REIT subsidiary, income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company’s tax provision has not changed materially subsequent to December 31, 2013. The Company is not currently under examination by the Internal Revenue Service.

Fair Value Measurements – ASC Topic 820 emphasizes that fair-value is a market-based measurement, not an entity-specific measurement. Therefore, a fair-value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair-value measurements, a fair-value hierarchy is established that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

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

Financial assets and liabilities measured at fair value in the financial statements on a recurring basis consist of the Company’s derivatives. The fair values of the derivatives are determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. The analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves (“significant other observable inputs”). The fair value calculation also includes an amount for risk of non-performance using “significant unobservable inputs” such as estimates of current credit spreads to evaluate the likelihood of default. The Company has concluded as of March 31, 2014 and December 31, 2013 that the fair value associated to “significant unobservable inputs” for risk of non-performance was insignificant to the overall fair value of the derivative agreements and, as a result, have determined that the relevant inputs for purposes of calculating the fair value of the derivative agreements, in their entirety, were based upon “significant other observable inputs.” The Company determined the fair value of derivatives using level 2 inputs. These methods of assessing fair value result in a general approximation of value, and such value may never be realized.

The Company’s financial instruments held at fair value are presented below as of March 31, 2014 and December 31, 2013 (dollars in thousands):

			Fair Value Measurements
	Carrying Value		Level 1		Level 2		Level 3

Financial Liabilities:
Interest rate swap liability(1)	$	320	$	—	$	320	$	—
December 31, 2013
Financial Liabilities:

(1) The Company used inputs from quoted prices for similar assets and liabilities in active markets that are directly or indirectly observable relating to the measurement of the interest rate swaps. The fair value measurement of the interest rate swaps have been classified as Level 2.

New Accounting Pronouncement

In April 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”. The amendments in the ASU change the criteria for reporting discontinued operations while enhancing disclosures in this area. The new guidance narrows the definition of discontinued operations to disposals that represent a strategic shift in operations and requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income and expenses of discontinued operations. The new guidance also requires disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The amendments in the ASU are effective for annual and interim reporting periods beginning on and after December 15, 2014. Early adoption is permitted. Adoption of this standard will currently have no effect on the Company’s financial statements.

Description of Business

1. Description of Business

QTS Realty Trust, Inc. (the “Company”) through its controlling interest in QualityTech, L.P. (the “Operating Partnership”) and the subsidiaries of the Operating Partnership, is engaged in the business of owning, acquiring, redeveloping and managing multi-tenant data centers. As of March 31, 2014 the Company’s portfolio consists of 10 properties with data centers located throughout the continental United States.

The Company was formed as a Maryland corporation on May 17, 2013. On October 15, 2013, the Company completed its initial public offering of 14,087,500 shares of Class A common stock, $0.01 par value per share (the “IPO”), including shares issued pursuant to the underwriters’ option to purchase additional shares, which was exercised in full, and received net proceeds of approximately $279 million. The Company intends to elect to be taxed as a real estate investment trust (“REIT”), for U.S. federal income tax purposes, commencing with its taxable year ended December 31, 2013.

Concurrently with the completion of the IPO, the Company consummated a series of transactions, including the merger of General Atlantic REIT, Inc. with the Company, pursuant to which it became the sole general partner and majority owner of the Quality Tech, LP, a Delaware limited partnership (the “Operating Partnership”). The Company contributed the net proceeds received from the IPO to the Operating Partnership in exchange for partnership units therein. As of March 31, 2014, the Company owned approximately 78.8% of the interests in the Operating Partnership. Substantially all of the Company’s assets are held by, and the Company’s operations are conducted through, the Operating Partnership. The Company’s interest in the Operating Partnership entitles the Company to share in cash distributions from, and in the profits and losses of, the Operating Partnership in proportion to the Company’s percentage ownership. As the sole general partner of the Operating Partnership, the Company generally has the exclusive power under the partnership agreement to manage and conduct the Operating Partnership’s business and affairs, subject to certain limited approval and voting rights of the limited partners. The Company’s board of directors manages the Company’s business and affairs.

Interest Rate Derivative Instruments

6. Interest Rate Derivative Instruments

The Company entered into interest rate cap and swap agreements with a notional amount of $150 million on February 8, 2012, which are designated as cash flow hedges for hedge accounting. In addition, an interest rate cap of an additional $50 million was in place as of December 31, 2013 with a capped LIBOR rate of 3% through December 18, 2015. For derivative instruments that are accounted for as hedges, the change in fair value for the effective portions of qualifying hedges is recorded through other comprehensive income (loss). The total unrealized gain recorded in other comprehensive income (loss) was $0.1 million and $0.1 million for the three months ended March 31, 2014 and March 31, 2013, respectively.

Interest expense related to payments on interest rate swaps for the three months ended March 31, 2014 and March 31, 2013 were $0.2 million and $0.1 million, respectively.

As of March 31, 2014 and December 31, 2013 the value of the interest rate swaps was a liability of $0.3 million and $0.5 million, respectively. These values were determined using Level 2 inputs within the valuation hierarchy.

(a) Unsecured Credit Facility – On May 1, 2013, the Company entered into an unsecured credit facility agreement with a syndicate of financial institutions in which KeyBank National Association serves as administrative agent (the “Unsecured Credit Facility”). Proceeds from the Unsecured Credit Facility were used to repay the Company’s prior secured credit facility. This unsecured credit facility has a term loan of $225 million, with a term of five years, and initially had a revolving credit facility of $350 million, with a term of four years, for an aggregate borrowing capacity of $575 million. The credit facility also provides for a $100 million accordion feature that could increase the amount of the facility up to $675 million, subject to certain conditions, including the consent of the administrative agent and obtaining necessary commitments.

The Unsecured Credit Facility requires monthly interest payments and requires the Company to comply with various quarterly covenant requirements relating to debt service coverage ratio, fixed charge ratio, leverage ratio and tangible net worth and various other operational requirements. In connection with the Unsecured Credit Facility, as of March 31, 2014, the Company had an additional $3 million letter of credit outstanding.

Amounts outstanding under the unsecured credit facility bear interest at a variable rate equal to, at our election, LIBOR or a base rate, plus a spread that will range, depending upon our leverage ratio, from 2.10% to 2.85% for LIBOR loans or 1.10% to 1.85% for base rate loans. As of March 31, 2014, the weighted average interest rate for amounts outstanding under our credit facility was 2.26%.

In February 2014, the Company expanded the capacity of its unsecured revolving credit facility by $50 million, increasing the unsecured revolving credit facility capacity to $400 million. In April 2014, the Company amended the credit facility to allow the Company to prepay the term loan with proceeds of any new unsecured debt until the outstanding balance is equal to or less than than $150 million rather than prepay the entire $225 million of the term loan as was previously required.

(b) Richmond Credit Facility – In December 2012, the Company entered into a credit facility secured by the Company’s Richmond data center (the “Richmond Credit Facility”). This credit facility had a total borrowing capacity of $80 million at December 31, 2012, which was increased to $100 million in January 2013. This credit facility also includes an accordion feature that allows the Company to increase the size of the credit facility up to $125 million and requires the Company to comply with covenants similar to the Unsecured Credit Facility. This credit facility bears interest at variable rates ranging from LIBOR plus 4.0% to LIBOR plus 4.5%. The interest rate at March 31, 2014 was LIBOR plus 4.00%, or 4.15% per annum based on the Company’s overall leverage ratio as defined in the agreement, and the loan has a stated maturity date of December 18, 2015 with an option to extend for one additional year.

(c) Atlanta-Metro Equipment Loan – On April 9, 2010, the Company entered into a $25 million loan to finance equipment related to an expansion project at the Company’s Atlanta-Metro data center (the “Atlanta-Metro Equipment Loan”). The loan originally featured monthly interest-only payments but now requires monthly interest and principal payments. The loan bears interest at 6.85%, amortizes over ten years and matures on June 1, 2020.

The annual remaining principal payment requirements as of March 31, 2014 per the contractual maturities and excluding extension options are as follows (in thousands):

2014	$	1,694
2015		72,397

2018		227,943

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

13. Fair Value of Financial Instruments

ASC Topic 825 requires disclosure of fair value information about financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practicable to estimate that value. In cases where quoted market prices are not available, fair values are based upon the application of discount rates to estimated future cash flows based upon market yields or by using other valuation methodologies. Considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, fair values are not necessarily indicative of the amounts the Company could realize on disposition of the financial instruments. The use of different market assumptions and/or estimation methodologies may have a material effect on estimated fair value amounts.

Short-term instruments: The carrying amounts of cash and cash equivalents, restricted cash approximate fair value.

Credit facilities and mortgage notes payable: The fair value of the Company’s floating rate mortgage loans was estimated using Level 2 “significant other observable inputs” such as available market information based on borrowing rates that the Company believes it could obtain with similar terms and maturities. At March 31, 2014, the fair value of the Atlanta-Metro Equipment Loan, based on current market rates, was approximately $17.6 million. The Company’s Unsecured Credit Facility and Richmond Credit Facility did not have interest rates which were materially different than current market conditions and therefore, the fair value of each of the credit facilities approximated the carrying value of each note.

Other debt instruments: The fair value of the Company’s other debt instruments (including capital leases) were estimated in the same manner as the credit facilities and mortgage notes payable above. Similarly, because each of these instruments did not have interest rates which were materially different than current market conditions and therefore, the fair value of each instrument approximated the respective carrying values.

7. Commitments and Contingencies

The Company is subject to various routine legal proceedings and other matters in the ordinary course of business. While resolution of these matters cannot be predicted with certainty, management believes, based upon information currently available, that the final outcome will not have a material adverse impact on the Company’s financial statements. The Company previously entered into a master service agreement with a third party Internet service provider. The Company was not receiving industry-standard quality of Internet and connectivity services and terminated the contract. The third party Internet service provider challenged the grounds for the Company’s termination and sued the Company in Georgia state court seeking the fees the Company owed prior to the termination plus a termination fee equal to the amount the Company would have paid had it not terminated the agreement. The Georgia state court ruled to limit damages, if any, to six months of unpaid fees. Additional claims related to a prior settlement agreement between the parties and the enforceability of an early termination clause in a separate agreement have been raised and are being litigated. The Company has established an accrual associated with this matter which is recorded as a component of accrued liabilities.

Partners' Capital, Equity and Incentive Compensation Plans

8. Partners’ Capital, Equity and Incentive Compensation Plans

The Company has the full power and authority to do all the things necessary to conduct the business of the Operating Partnership.

As of March 31, 2014, the Operating Partnership had three classes of limited partnership units outstanding: Class A units of limited partnership interest (“Class A units”), Class RS LTIP units of limited partnership interest (“Class RS units”) and Class O LTIP units of limited partnership units (“Class O Units”). The Class A Units are redeemable at any time on or after one year following the later of the beginning of the first full calendar month following the completion of the IPO or the date of initial issuance. The Company may in its sole discretion elect to assume and satisfy the redemption amount with cash or its shares. Class RS units or Class O units were issued upon grants made under the QualityTech, LP 2010 Equity Incentive Plan (the “2010 Equity Plan”). Class RS units and Class O units may be subject to vesting and are pari passu with Class A units. Vested Class RS units and Class O units are convertible into Class A units based on formulas contained in the partnership agreement of the Operating Partnership.

In connection with its IPO, the Company issued Class A common stock and Class B common stock. Class B common stock entitles the holder to 50 votes per share and was issued to enable the Company’s Chief Executive Officer to exchange 2% of his Operating Partnership units so he may have a vote proportionate to his economic interest in the Company. Also in connection with its IPO, the Company adopted the QTS Realty Trust, Inc. 2013 Equity Incentive plan (the “2013 Equity Incentive Plan”), which authorized 1.75 million shares to be issued under the plan, including options to purchase Class A common stock, restricted Class A common stock, Class O units and Class RS units.

The following is a summary of award activity under the 2010 Equity Incentive Plan and 2013 Equity Incentive Plan and related information for the three months ended March 31, 2014:

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2014

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation – The accompanying financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included.

Use of Estimates

Use of Estimates – The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of fixed assets, allowances for doubtful accounts and deferred tax assets and the valuation of derivatives, real estate assets, acquired intangible assets and certain accruals.

Principles of Consolidation

Principles of Consolidation – The consolidated financial statements include the accounts of QTS Realty Trust, Inc. and its majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the financial statements.

Real Estate Assets

Real Estate Assets – Real estate assets are reported at cost. All capital improvements for the income-producing properties that extend their useful lives are capitalized to individual property improvements and depreciated over their estimated useful lives. Depreciation is generally provided on a straight-line basis over 40 years from the date the property was placed in service. Property improvements are depreciated on a straight-line basis over the life of the respective improvement ranging from 20 to 40 years from the date the components were placed in service. Leasehold improvements are depreciated over the lesser of 20 years or through the end of the respective life of the lease. Repairs and maintenance costs are expensed as incurred. The aggregate depreciation charged to operations was $10.2 million and $8.5 million for the three months ended March 31, 2014 and 2013, respectively. The Company capitalizes certain development costs, including internal costs incurred in connection with development. The capitalization of costs during the construction period (including interest and related loan fees, property taxes and other direct and indirect costs) begins when development efforts commence and ends when the asset is ready for its intended use. Capitalization of such costs, excluding interest, aggregated to $2.2 million and $1.7 million for the three months ended March 31, 2014 and 2013, respectively. Interest is capitalized during the period of development by first applying the Company’s actual borrowing rate on the related asset and second, to the extent necessary, by applying the Company’s weighted average effective borrowing rate to the actual development and other costs expended during the construction period. Interest is capitalized until the property is ready for its intended use. Interest costs capitalized totaled $1.6 million and $1.0 million for the three months ended March 31, 2014 and 2013, respectively.

Acquisition of Real Estate

Acquisition of Real Estate – Acquisitions of real estate are either accounted for as asset acquisitions or business combinations depending on facts and circumstances. Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired in accordance to the accounting requirements of ASC 805, Business Combinations, which requires the recording of net assets of acquired businesses at fair value. The fair value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and improvements, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, value of in-place leases and value of customer relationships.

In developing estimates of fair value of acquired assets and assumed liabilities, management analyzed a variety of factors including market data, estimated future cash flows of the acquired operations, industry growth rates, current replacement cost for fixed assets and market rate assumptions for contractual obligations. Such a valuation requires management to make significant estimates and assumptions, particularly with respect to the intangible assets.

Intangible assets and liabilities include in-place leases and customer relationships.

Acquired in-place leases are amortized as amortization expense on a straight-line basis over the remaining life of the underlying leases. Amortization of acquired in place lease costs, including write-offs for terminated leases totaled $0.6 million and $0.6 million for the three months ended March 31, 2014 and 2013, respectively.

Acquired customer relationships are amortized as amortization expense on a straight-line basis over the expected life of the customer relationship. Amortization of acquired customer relationships totaled $0.3 million and $0.4 million for the three months ended March 31, 2014 and 2013, respectively.

Impairment of Long-Lived and Intangible Assets

Impairment of Long-Lived and Intangible Assets – The Company reviews its long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Recoverability of assets to be held and used is generally measured by comparison of the carrying amount to the future net cash flows, undiscounted and without interest, expected to be generated by the asset group. If the net carrying value of the asset exceeds the value of the undiscounted cash flows, the fair value of the asset is assessed and may be considered impaired. An impairment loss is recognized based on the excess of the carrying amount of the impaired asset over its fair value. No impairment losses were recorded for the three months ended March 31, 2014 and 2013, respectively.

Cash and Cash Equivalents

Cash and Cash Equivalents – The Company considers all demand deposits and money market accounts purchased with a maturity date of three months or less at the date of purchase to be cash equivalents. The Company’s account balances at one or more institutions periodically exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is concentration of credit risk related to amounts on deposit in excess of FDIC coverage. The Company mitigates this risk by depositing a majority of its funds with several major financial institutions. The Company also has not experienced any losses and, therefore, does not believe that the risk is significant.

Deferred Costs

Deferred Costs – Deferred costs, net, on the Company’s balance sheets include both financing costs and leasing costs.

Deferred financing costs represent fees and other costs incurred in connection with obtaining debt and are amortized over the term of the loan and are included in interest expense. Amortization of the deferred financing costs was $0.6 million and $0.9 million for the three months ended March 31, 2014 and 2013, respectively. In addition, during the three months ended March 31, 2013, the Company wrote off unamortized financing costs of $1.1 million in connection with an asset securitization which the Company did not pursue due to the expansion of the credit facility. Deferred financing costs, net of accumulated amortization are as follows:

	March 31,
	2014			December 31,
(dollars in thousands)	(unaudited)			2013
Deferred financing costs	$	9,526		$	9,159
Accumulated amortization		(2,450	)		(1,867	)
Deferred financing costs, net	$	7,076		$	7,292

Deferred leasing costs consist of external fees and internal costs incurred in the successful negotiations of leases and 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. Amortization of deferred leasing costs totaled $1.3 million and $1.0 million for the three months ended March 31, 2014 and 2013, respectively. Deferred leasing costs, net of accumulated amortization are as follows:

	March 31,
	2014			December 31,
(dollars in thousands)	(unaudited)			2013
Deferred leasing costs	$	19,282		$	17,374
Accumulated amortization		(7,201	)		(5,516	)
Deferred leasing costs, net	$	12,081		$	11,858

Advance Rents and Security Deposits

Advance Rents and Security Deposits – Advance rents, typically prepayment of the following month’s rent, consist of payments received from customers prior to the time they are earned and are recognized as revenue in subsequent periods when earned. Security deposits are collected from customers at the lease origination and are generally refunded to customers upon lease expiration.

Deferred Income

Deferred Income – Deferred income generally results from non-refundable charges paid by the customer at lease inception to prepare their space for occupancy. The Company records this initial payment, commonly referred to as set-up fees, as a deferred income liability which amortizes into rental revenue over the term of the related lease on a straight-line basis. Deferred income was $8.1 million and $7.9 million as of March 31, 2014 and December 31, 2013, respectively. Additionally, $1.2 million and $1.1 million of deferred income was amortized into revenue for the three months ended March 31, 2014 and 2013, respectively.

Interest Rate Derivative Instruments

Interest Rate Derivative Instruments – The Company utilizes derivatives to manage its interest rate exposure. During February 2012, the Company entered into interest rate swaps with a notional amount of $150 million which are cash flow hedges and qualify for hedge accounting. For these hedges, the effective portion of the change in fair value is recognized through other comprehensive income or loss. Amounts are reclassified out of other comprehensive income (loss) as the hedged item is recognized in earnings, either for ineffectiveness or for amounts paid relating to the hedge. As there was no ineffectiveness recorded in the periods presented, the Company has reflected the change in the fair value of the instrument in other comprehensive income (loss). For the ineffective portions of qualifying hedges, the change in fair value is recorded through interest expense in the respective period.

Equity-based Compensation

Equity-based Compensation –All equity-based compensation is measured at fair value on the grant date or date of modification, as applicable, and recognized in earnings over the requisite service period. Depending upon the settlement terms of the awards, all or a portion of the fair value of equity-based awards may be presented as a liability or as equity in the consolidated balance sheets. Equity-based compensation costs are measured based upon their estimated fair value on the date of grant or modification. Equity-based compensation expense net of forfeited and repurchased awards acquired of $0.9 million and $0.4 million was recorded for the three months ended March 31, 2014 and 2013, respectively.

Rental Revenue

Rental Revenue – The Company, as a lessor, has retained substantially all of the risks and benefits of ownership and accounts for its leases as operating leases. For lease agreements that provide for scheduled 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 has been provided to the customer. The amount of the straight-line rent receivable on the balance sheets included in rents and other receivables, net was $3.1 million and $2.9 million as of March 31, 2014 and December 31, 2013, respectively. Rental revenue also includes amortization of set-up fees which are amortized over the term of the respective lease as discussed above.

Allowance for Uncollectible Accounts Receivable

Allowance for Uncollectible Accounts Receivable – Rents receivable are recognized when due and are carried at cost, less an allowance for doubtful accounts. The Company records a provision for losses on rents receivable equal to the estimated uncollectible accounts, which is based on management’s historical experience and a review of the current status of the Company’s receivables. As necessary, the Company also establishes an appropriate allowance for doubtful accounts for receivables arising from the straight-lining of rents. The aggregate allowance for doubtful accounts was $1.3 million and $0.9 million as of March 31, 2014 and December 31, 2013, respectively.

Capital Lease

Capital Lease – The Company evaluates leased real estate to determine whether the lease should be classified as a capital or operating lease in accordance with U.S GAAP.

The Company periodically enters into capital leases for certain equipment. The outstanding liabilities for the capital leases were $2.7 million and $2.5 million as of March 31, 2014 and December 31, 2013, respectively. Depreciation related to the associated assets is included in depreciation and amortization expense in the Statements of Operations and Comprehensive Income (Loss).

Recoveries from Customers

Recoveries from Customers – Certain customer leases contain provisions under which the customers reimburse the Company for a portion of the property’s real estate taxes, insurance and other operating expenses, which include certain power and cooling-related charges. The reimbursements are included in revenue as recoveries from customers in the Statements of Operations and Comprehensive Income (Loss) in the period the applicable expenditures are incurred. Certain customer leases are structured to provide a fixed monthly billing amount that includes an estimate of various operating expenses, with all revenue from such leases included in rental revenues.

Cloud and Managed Services Revenue

Cloud and Managed Services Revenue – The Company may provide both its cloud product and use of its managed services to its customers on an individual or combined basis. Service fee revenue is recognized as the revenue is earned, which generally coincides with the services being provided.

Segment Information

Segment Information – The Company manages its business as one operating segment and thus one reportable segment consisting of a portfolio of investments in data centers located in the United States.

Customer Concentrations

Customer Concentrations – As of March 31, 2014, two of the Company’s customers represented 8.0% and 5.5%, respectively, of its total monthly rental revenue. No other customers exceeded 5% of total monthly rental revenue.

As of March 31, 2014, six of the Company’s customers exceeded 5% of total accounts receivable. In aggregate, these six customers accounted for 39.5% of total accounts receivable. None of these six customers individually exceeded 10% of total accounts receivable.

Income Taxes

Income Taxes – The Company is obligated to comply with Internal Revenue Service real estate investment trust (“IRS REIT”) tax regulations in accordance with the unit holders’ agreement. In order to comply with this obligation, the Company elected for one of its existing subsidiaries to be taxed as a taxable REIT subsidiary under the IRS REIT tax regulations. The taxable REIT subsidiary is allocated income and expense based on IRS REIT tax regulations.

For the taxable REIT subsidiary, income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company’s tax provision has not changed materially subsequent to December 31, 2013. The Company is not currently under examination by the Internal Revenue Service.

Fair Value Measurements

Fair Value Measurements – ASC Topic 820 emphasizes that fair-value is a market-based measurement, not an entity-specific measurement. Therefore, a fair-value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair-value measurements, a fair-value hierarchy is established that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

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

Financial assets and liabilities measured at fair value in the financial statements on a recurring basis consist of the Company’s derivatives. The fair values of the derivatives are determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. The analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves (“significant other observable inputs”). The fair value calculation also includes an amount for risk of non-performance using “significant unobservable inputs” such as estimates of current credit spreads to evaluate the likelihood of default. The Company has concluded as of March 31, 2014 and December 31, 2013 that the fair value associated to “significant unobservable inputs” for risk of non-performance was insignificant to the overall fair value of the derivative agreements and, as a result, have determined that the relevant inputs for purposes of calculating the fair value of the derivative agreements, in their entirety, were based upon “significant other observable inputs.” The Company determined the fair value of derivatives using level 2 inputs. These methods of assessing fair value result in a general approximation of value, and such value may never be realized.

The Company’s financial instruments held at fair value are presented below as of March 31, 2014 and December 31, 2013 (dollars in thousands):

			Fair Value Measurements
	Carrying Value		Level 1		Level 2		Level 3
March 31, 2014
Financial Liabilities:
Interest rate swap liability(1)	$	320	$	—	$	320	$	—
December 31, 2013
Financial Liabilities:
Interest rate swap liability(1)	$	453	$	—	$	453	$	—

(1) The Company used inputs from quoted prices for similar assets and liabilities in active markets that are directly or indirectly observable relating to the measurement of the interest rate swaps. The fair value measurement of the interest rate swaps have been classified as Level 2.

New Accounting Pronouncement

New Accounting Pronouncement

In April 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”. The amendments in the ASU change the criteria for reporting discontinued operations while enhancing disclosures in this area. The new guidance narrows the definition of discontinued operations to disposals that represent a strategic shift in operations and requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income and expenses of discontinued operations. The new guidance also requires disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify for discontinued operations reporting. The amendments in the ASU are effective for annual and interim reporting periods beginning on and after December 15, 2014. Early adoption is permitted. Adoption of this standard will currently have no effect on the Company’s financial statements.

Short Term Instruments

Short-term instruments: The carrying amounts of cash and cash equivalents, restricted cash approximate fair value.

Credit Facilities and Mortgage Notes Payable

Credit facilities and mortgage notes payable: The fair value of the Company’s floating rate mortgage loans was estimated using Level 2 “significant other observable inputs” such as available market information based on borrowing rates that the Company believes it could obtain with similar terms and maturities. At March 31, 2014, the fair value of the Atlanta-Metro Equipment Loan, based on current market rates, was approximately $17.6 million. The Company’s Unsecured Credit Facility and Richmond Credit Facility did not have interest rates which were materially different than current market conditions and therefore, the fair value of each of the credit facilities approximated the carrying value of each note.

Other Debt Instruments

Other debt instruments: The fair value of the Company’s other debt instruments (including capital leases) were estimated in the same manner as the credit facilities and mortgage notes payable above. Similarly, because each of these instruments did not have interest rates which were materially different than current market conditions and therefore, the fair value of each instrument approximated the respective carrying values.

14. Subsequent Events

On April 8, 2014, the Company paid its regular quarterly cash dividend of $0.29 per common share to stockholders of record as of the close of business on March 20, 2014.

On April 11, 2014, the Company amended the credit agreement governing its Unsecured Credit Facility to require the Company to use proceeds of any new unsecured debt of the Operating Partnership, the Company or any of their respective subsidiaries to prepay term loans under the agreement until the outstanding balance of the term loans is equal to or less than $150 million, rather than requiring prepayment in full.

In April 2014, the Company decided to reduce the number of employees, primarily located in its New Jersey market. Those positions will be relocated to the new operations center in Suwanee, GA and its corporate headquarters in Overland Park, KS. This will result in an estimated aggregate, non-recurring charge of approximately $1.5 million, of which approximately $1.3 million is expected to occur in the second quarter of 2014 and the remainder will impact third quarter 2014 results.

On May 6, 2014, the Company’s Board of Directors authorized payment of a regular quarterly cash dividend of $0.29 per common share, payable on July 8, 2014, to stockholders of record as of the close of business on June 20, 2014.
