NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2017

(unaudited)

1. Organization and Description of Business

CoreSite Realty Corporation (the “Company,” “we,” “us,” or “our”) was organized in the state of Maryland on February 17, 2010, and is a fully-integrated, self-administered, and self-managed real estate investment trust (“REIT”). Through our controlling interest in CoreSite, L.P. (our “Operating Partnership”), we are engaged in the business of owning, acquiring, constructing and operating data centers. As of March 31, 2017, the Company owns a 70.9% common interest in our Operating Partnership and affiliates of The Carlyle Group and others own a 29.1% interest in our Operating Partnership. See additional discussion in Note 8, Noncontrolling Interests — Operating Partnership.

2. Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared by our management in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in compliance with the rules and regulations of the U.S. Securities and Exchange Commission. Accordingly, these unaudited condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of our management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The results of operations for the three months ended March 31, 2017, are not necessarily indicative of the expected results for the year ending December 31, 2017. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016. Intercompany balances and transactions have been eliminated upon consolidation.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance codified in Accounting Standards Codification (“ASC”) Topic 606, Revenue Recognition — Revenue from Contracts with Customers, which amends the guidance in former ASC 605, Revenue Recognition. The standard establishes a five-step model framework which recognizes revenue as an entity transfers control of goods or services to the customer and requires enhanced disclosures. This standard does not apply to leases, which will be accounted for under ASC Topic 842, Leases. The revenue standard is effective for interim and annual reporting periods beginning after December 15, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. As ASC Topic 606 does not impact lessor accounting, we do not believe this standard will significantly impact our accounting for rental revenue. In addition, we do not anticipate a significant impact to our accounting for power, interconnection, tenant reimbursement and other revenue.

In February 2016, the FASB issued guidance codified in ASC Topic 842, Leases, which amends the guidance in former ASC 840, Leases. The main principle of ASC 842 requires lessees to recognize the assets and liabilities that arise from nearly all leases on the consolidated balance sheet. Lessor accounting remains mainly consistent with current guidance, with the majority of changes allowing for better alignment with the new lessee model and ASC Topic 606. The standard is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. The standard requires a modified retrospective transition approach.

We plan to adopt ASC Topic 842 and ASC Topic 606 effective January 1, 2018, which will result in a transition date of January 1, 2016. As a lessee we do not anticipate the classification of our leases to change, but we will be required to recognize a lease liability and corresponding right-of-use asset on our consolidated balance sheets for all of our operating leases. Using the fixed noncancellable term of all existing data center leases, excluding renewal options, we estimate the initial lease liability and right-of-use asset will be approximately $100 million on our consolidated balance sheet as of the transition date. As we continue to evaluate the provisions of ASC Topic 842, we will evaluate our existing renewal options within our data center leases and ultimately conclude as to whether we are, or are not, reasonably certain, based on relevant factors that may create an economic incentive for us, to exercise renewal options for each of our data center leases. If we determine that we are reasonably certain to exercise all renewal options for each lease, we estimate the

Table of Contents

initial lease liability and right-of-use asset will be approximately $300 million on our consolidated balance sheet as of the transition date. Subject to our evaluation of whether we are reasonably certain to exercise renewal options for each of our data center leases as well as resolution of other implementation items, we estimate our straight-line rental expense could increase up to $1.3 million and $1.2 million within our consolidated statement of operations for the three months ended March 31, 2017, and 2016, respectively.

In accordance with ASC Topic 842, lessor accounting for our leases remains largely unchanged, apart from the narrower scope of initial direct costs that can be capitalized. The new standard defines initial direct costs as only incremental costs of signing a lease. Internal sales employees’ compensation, payroll-related fringe benefits and certain external legal fees related to the execution of successful lease agreements will not meet the definition of initial direct costs under the new standard and will be accounted for as a sales and marketing expense in the consolidated statement of operations upon adoption of ASC Topic 842. We estimate sales and marketing expense could increase up to $0.5 million for both the three months ended March 31, 2017, and 2016. We are currently evaluating the other impacts of ASC Topic 842 and ASC Topic 606 on our significant accounting policies and consolidated financial statements.

In August 2016, the FASB issued guidance codified in Accounting Standards Update (“ASU”) Topic 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The standard provides guidance on eight specific cash flow classification issues including debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, and separately identifiable cash flows and application of the predominance principle. The standard will be effective for the fiscal year beginning January 1, 2018, and subsequent interim periods. We do not expect the provisions of ASC 2016-15 to have a material impact on our consolidated financial statements.

In January 2017, the FASB issued guidance codified in ASU Topic 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. ASU 2017-04 simplifies the accounting for goodwill impairment by eliminating the process of measuring the implied value of goodwill, known as step two, from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The standard will be effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted. We do not expect the provisions of ASC 2017-04 to have a material impact on our consolidated financial statements.

Use of Estimates

The preparation of these unaudited condensed consolidated financial statements in conformity with GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingencies at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. We evaluate our estimates, including those related to assessing the carrying values of our real estate properties, goodwill, accrued liabilities and performance-based equity compensation plans. We base our estimates on historical experience, current market conditions, and various other assumptions that we believe to be reasonable under the circumstances. Actual results may vary from those estimates and those estimates could vary under different assumptions or conditions.

Investments in Real Estate

Real estate investments are carried at cost less accumulated depreciation and amortization. The cost of real estate includes the purchase price of property and leasehold improvements. Expenditures for maintenance and repairs are expensed as incurred. Significant renovations and betterments that extend the economic useful lives of assets are capitalized. During land development and construction periods, we capitalize construction costs, legal fees, financing costs, real estate taxes and insurance, rent expense and internal costs of personnel performing development, if such costs are incremental and identifiable to a specific development project. Capitalization of costs begins upon commencement of development efforts and ceases when the property is ready for its intended use and held available for occupancy. Interest is capitalized during the period of development based upon applying the weighted-average borrowing rate to the actual development costs expended. Capitalized interest costs were $0.6 million and $1.1 million for the three months ended March 31, 2017, and 2016, respectively.

Depreciation and amortization are calculated using the straight-line method over the following useful lives of the assets:

Table of Contents


Buildings		27 to 40 years
Building improvements		1 to 10 years
Leasehold improvements		The shorter of the lease term or useful life of the asset

Depreciation expense was $26.8 million and $20.1 million for the three months ended March 31, 2017, and 2016, respectively.

Acquisition of Investment in Real Estate

When accounting for business combinations and asset acquisitions, the fair value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and building improvements, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, value of in-place leases and the value of customer relationships.

The fair value of the land and building of an acquired property is determined by valuing the property as if it were vacant, and the “as-if-vacant” fair value is then allocated to land and building based on management's determination of the fair values of these assets. Management determines the as-if-vacant fair value of a property using methods similar to those used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases.

The fair value of intangibles related to in-place leases includes the value of lease intangibles for above-market and below-market leases, lease origination costs, and customer relationships, determined on a lease-by-lease basis. Above-market and below-market leases are valued based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management's estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining noncancelable term of the lease and, for below-market leases, over a time period equal to the initial term plus any below-market fixed rate renewal periods. Lease origination costs include estimates of costs avoided associated with leasing the property, including tenant allowances and improvements and leasing commissions. Customer relationship intangibles relate to the additional revenue opportunities expected to be generated through interconnection services and utility services to be provided to the in-place lease tenants.

The capitalized values for above and below-market lease intangibles, lease origination costs, and customer relationships are amortized over the term of the underlying leases or the expected customer relationship. Amortization related to above-market and below-market leases where the Company is the lessor is recorded as either a reduction of or an increase to rental revenue, amortization related to above-market and below-market leases where the Company is the lessee is recorded as either a reduction of or an increase to rent expense. If a lease is terminated prior to its stated expiration, all unamortized amounts relating to that lease are written off.

The carrying value of intangible assets is reviewed for impairment in connection with its respective asset group whenever events or changes in circumstances indicate that the asset group may not be recoverable. An impairment loss is recognized if the carrying amount of the asset group is not recoverable and its carrying amount exceeds its estimated fair value. No impairment loss related to these intangible assets was recognized for the three months ended March 31, 2017, or 2016.

The excess of the cost of an acquired business over the net of the amounts assigned to assets acquired (including identified intangible assets) and liabilities assumed is recorded as goodwill. As of March 31, 2017, and December 31, 2016, we had approximately $41.2 million of goodwill at each date. The Company’s goodwill has an indeterminate life and is not amortized, but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired. No impairment loss was recognized for the three months ended March 31, 2017, or 2016.

Cash and Cash Equivalents

Cash and cash equivalents include all non-restricted cash held in financial institutions and other non-restricted highly liquid short-term investments with original maturities at acquisition of three months or less.

Table of Contents

Deferred Costs

Deferred leasing costs include commissions paid to third parties, including brokers, leasing and referral agents, and internal sales commissions paid to employees for successful execution of lease agreements. These commissions and other direct and incremental costs incurred to obtain new customer leases are capitalized and amortized over the term of the related leases using the straight-line method. If a customer lease terminates prior to the expiration of its initial term, any unamortized deferred costs related to the lease are written off to amortization expense. Deferred leasing costs are included within other assets in the condensed consolidated balance sheets and consisted of the following, net of amortization, as of March 31, 2017, and December 31, 2016 (in thousands):

	2017		2016
Internal sales commissions	$	18,493	$	18,748
Third party commissions		12,883		13,643
External legal counsel		742		730
Total	$	32,118	$	33,121

Deferred financing costs include costs incurred in connection with obtaining debt and extending existing debt. These financing costs are capitalized and amortized on a straight-line basis, which approximates the effective-interest method, over the term of the loan and the amortization is included as a component of interest expense. Depending on the type of debt instrument, deferred financing costs are reported either in other assets or as a direct deduction from the carrying amount of the related debt liabilities in our condensed consolidated balance sheets.

Recoverability of Long-Lived Assets

We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment is recognized when estimated expected future cash flows (undiscounted and without interest charges) are less than the carrying amount of the assets. The estimation of expected future net cash flows is inherently uncertain and relies, to a considerable extent, on assumptions regarding current and future economics and market conditions and the availability of capital. If, in future periods, there are changes in the estimates or assumptions incorporated into the impairment review analysis, the changes could result in an adjustment to the carrying amount of the long-lived assets. To the extent that impairment has occurred, the excess of the carrying amount of long-lived assets over its estimated fair value would be recognized as an impairment loss charged to net income. For the three months ended March 31, 2017, and 2016, no impairment of long-lived assets was recognized.

Derivative Instruments and Hedging Activities

We reflect all derivative instruments at fair value as either assets or liabilities on the condensed consolidated balance sheets. For those derivative instruments that are designated and qualify as hedging instruments, we record the effective portion of the gain or loss on the hedging instruments as a component of accumulated other comprehensive income or loss. Any ineffective portion of a derivative's change in fair value is immediately recognized within net income. For derivatives that do not meet the criteria for hedge accounting, changes in fair value are immediately recognized within net income. See additional discussion in Note 6, Derivatives and Hedging Activities.

Internal-Use Software

We recognize internal-use software development costs based on the development stage of the project and nature of the cost. Internal and external costs incurred during the preliminary project stage are expensed as they are incurred. Internal and external costs incurred to develop internal-use software during the application development stage are capitalized. Internal and external training costs and maintenance costs during the post-implementation-operation stage are expensed as incurred. Completed projects are placed into service and amortized over the estimated useful life of the software. No impairment was recognized related to internal-use software in the condensed consolidated statements of operations for the three months ended March 31, 2017, and 2016.

Revenue Recognition

All customer leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the customer’s lease term. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in deferred rent receivable and included in other assets in the condensed consolidated balance sheets. If a lease terminates prior to its stated expiration, the deferred rent receivable relating to that lease is written off as a reduction of rental revenue.

When arrangements include multiple elements, the revenue associated with separate elements is allocated based on the relative fair values of those elements. The revenue associated with each element is then recognized as earned. Interconnection services and additional space services are considered as separate earnings processes that are provided and completed on a month-to-month basis and revenue is recognized in the period that services are performed. Customer set-up charges and utility installation fees are initially deferred and recognized over the term of the lease arrangement as revenue.

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

Above-market and below-market lease intangibles that were acquired are amortized on a straight-line basis as decreases and increases, respectively, to rental revenue over the remaining noncancelable term of the underlying leases. For both the three months ended March 31, 2017, and 2016, the net effect of amortization of acquired above-market and below-market leases resulted in an increase to rental revenue of $0.1 million.

A provision for uncollectible accounts is recorded if a receivable balance relating to contractual rent, rent recorded on a straight-line basis, tenant reimbursements or other billed amounts is considered by management to be uncollectible. At March 31, 2017, and December 31, 2016, the allowance for doubtful accounts totaled less than $0.1 million and $0.2 million, respectively.

Share-Based Compensation

We account for share-based compensation using the fair value method of accounting. The estimated fair value of the stock options granted by us is calculated based on the Black-Scholes option-pricing model. The fair value of restricted share-based and Operating Partnership unit compensation is based on the fair value of our common stock on the date of the grant. The fair value of performance share awards, which have a market condition, is based on a Monte Carlo simulation. The fair value for all share-based compensation is amortized on a straight-line basis over the vesting period.

Asset Retirement and Environmental Remediation Obligations

We record accruals for estimated asset retirement and environmental remediation obligations. The obligations relate primarily to the removal of asbestos during development of properties as well as the estimated equipment removal costs upon termination of a certain lease where we are the lessee. At March 31, 2017, and December 31, 2016, the amount included in unearned revenue, prepaid rent and other liabilities on the condensed consolidated balance sheets was approximately $1.4 million.

Income Taxes

We elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”), commencing with our taxable year ended December 31, 2010. To qualify as a REIT, we are required to distribute at least 90% of our taxable income to our stockholders and meet various other requirements imposed by the Code relating to such matters as operating results, asset holdings, distribution levels and diversity of stock ownership. Provided we qualify for taxation as a REIT, we generally are not subject to corporate level federal income tax on the earnings distributed currently to our stockholders. If we fail to qualify as a REIT in any taxable year, and are unable to avail ourselves of certain savings provisions set forth in the Code, all of our taxable income would be subject to federal income tax at regular corporate rates, including any applicable alternative minimum tax.

To maintain REIT status, we must distribute a minimum of 90% of our taxable income. However, it is our policy and intent, subject to change, to distribute 100% of our taxable income and therefore, no provision is required in the

Table of Contents

accompanying condensed consolidated financial statements for federal income taxes with regards to activities of the REIT and its subsidiary pass-through entities. The allocable share of taxable income is included in the income tax returns of its stockholders. The Company is subject to the statutory requirements of the locations in which it conducts business. State and local income taxes are accrued as deemed required in the best judgment of management based on analysis and interpretation of respective tax laws.

We have elected to treat certain subsidiaries as taxable REIT subsidiaries (“TRS”). Certain activities that we undertake must be conducted by a TRS, such as services for our tenants that could be considered otherwise impermissible for us to perform and holding assets that we cannot hold directly. A TRS is subject to corporate level federal and state income taxes.

Deferred income taxes are recognized in certain taxable entities. Deferred income tax generally is a function of the period's temporary differences (items that are treated differently for tax purposes than for financial reporting purposes), the utilization of tax net operating losses generated in prior years that previously had been recognized as deferred income tax assets and the reversal of any previously recorded deferred income tax liabilities. A valuation allowance for deferred income tax assets is provided if we believe all or some portion of the deferred income tax asset may more likely than not be realized. Any increase or decrease in the valuation allowance resulting from a change in circumstances that causes a change in the estimated realizability of the related deferred income tax asset is included in deferred tax expense. As of March 31, 2017, and December 31, 2016, the gross deferred income taxes were not material.

We currently have no liabilities for uncertain income tax positions. The earliest tax year for which we are subject to examination is 2013.

Concentration of Credit Risks

Our cash and cash equivalents are maintained in various financial institutions, which, at times, may exceed federally insured limits. We have not experienced any losses in such accounts, and management believes that the Company is not exposed to any significant credit risk in this area. We have no off-balance sheet concentrations of credit risk, such as foreign exchange contracts, option contracts, or foreign currency hedging arrangements.

Segment Information

We manage our business as one reportable segment consisting of investments in data centers located in the United States. Although we provide services in several markets, these operations have been aggregated into one reportable segment based on the similar economic characteristics amongst all markets, including the nature of the services provided and the type of customers purchasing these services.

See Note 6 – Derivatives and Hedging Activities.

Subsequent Debt Financing

On April 19, 2017, and April 20, 2017, our Operating Partnership executed two separate financing transactions resulting in additional liquidity of $275 million, which will be used to refinance existing debt and for general corporate purposes. The new debt is comprised of a $100 million increase to the current 2019 Term Loan with a new five-year term maturing in April 2022 and the issuance of $175 million of 3.91% senior notes due April 2024. See “2019 Senior Unsecured Term Loan” and “2024 Senior Unsecured Notes” below for additional discussion.

Revolving Credit Facility

On February 2, 2016, our Operating Partnership and certain subsidiary co-borrowers entered into the first amendment to the third amended and restated credit agreement (as amended, the “Credit Agreement”) with a group of lenders for which KeyBank National Association acts as the administrative agent. The Credit Agreement maturity date is June 24, 2019,

Table of Contents

with a one-time extension option, which, if exercised, would extend the maturity date to June 24, 2020. The exercise of the extension option is subject to the payment of an extension fee equal to 10 basis points of the total commitment under the Credit Agreement at initial maturity and certain other customary conditions. The Credit Agreement includes a total commitment of $600 million, providing for a $350 million revolving credit facility, a $150 million unsecured term loan scheduled to mature on June 24, 2020, and a $100 million unsecured term loan scheduled to mature on February 2, 2021. See “2020 Senior Unsecured Term Loan” and “2021 Senior Unsecured Term Loan” below for a discussion of the $150 million and $100 million term loans. The Credit Agreement contains an accordion feature, which allows our Operating Partnership to increase the total commitment from $600 million to $800 million, under specified circumstances, including securing capital from new or existing lenders.

Borrowings under the revolving credit facility bear interest at a variable rate per annum equal to either (i) LIBOR plus 155 basis points to 225 basis points, or (ii) a base rate plus 55 basis points to 125 basis points, each depending on our Operating Partnership’s leverage ratio. At March 31, 2017, our Operating Partnership’s leverage ratio was 22.4% and the interest rate was LIBOR plus 155 basis points.

The total amount available for borrowing under the revolving credit facility, which is part of the Credit Agreement, is equal to the lesser of $350.0 million or the availability calculated based on our unencumbered asset pool. As of March 31, 2017, the borrowing capacity was $350.0 million. As of March 31, 2017, $223.0 million was borrowed and outstanding, $4.5 million was outstanding under letters of credit and therefore $122.5 million remained available for us to borrow under the revolving credit facility.

Our ability to borrow under the Credit Agreement is subject to ongoing compliance with a number of financial covenants and other customary restrictive covenants, including, among others:

a maximum leverage ratio (defined as total consolidated indebtedness to total gross asset value) of 60%, which, as of March 31, 2017, was 22.4%

a maximum secured debt ratio (defined as total consolidated secured debt to total gross asset value) of 40%, which, as of March 31, 2017, was 0.0

a minimum fixed charge coverage ratio (defined as adjusted consolidated earnings before interest, taxes, depreciation and amortization to consolidated fixed charges) of 1.7 to 1.0, which, as of March 31, 2017, was 8.6 to 1.0; and

a maximum unhedged variable rate debt ratio (defined as unhedged variable rate indebtedness to gross asset value) of 30%, which, as of March 31, 2017, our unhedged variable rate debt ratio was 12.2%.

As of March 31, 2017, we were in compliance with all of the financial covenants under the Credit Agreement.

2019 Senior Unsecured Term Loan

On January 31, 2014, our Operating Partnership and certain subsidiaries entered into a $100 million senior unsecured term loan (the “2019 Term Loan”). The 2019 Term Loan has a five-year term and contains an accordion feature, which allows our Operating Partnership to increase the total commitments by $100 million, to $200 million, under specified circumstances, including securing capital from new or existing lenders. The 2019 Term Loan ranks pari passu with the 2020 Term Loan, the 2021 Term Loan, the 2023 Notes, the 2024 Notes and the Credit Agreement and contains the same financial covenants and other customary restrictive covenants. As of March 31, 2017, we were in compliance with all of the financial covenants under the 2019 Term Loan.

The borrowings under the 2019 Term Loan bear interest at a variable rate per annum equal to either (i) LIBOR plus 175 basis points to 265 basis points, or (ii) a base rate plus 75 basis points to 165 basis points, each depending on our Operating Partnership's leverage ratio. At March 31, 2017, our Operating Partnership’s leverage ratio was 22.4% and the interest rate was LIBOR plus 175 basis points.

On April 19, 2017, our Operating Partnership and certain subsidiaries amended the 2019 Term Loan to (i) exercise the accordion feature to increase the total commitments to $200 million, (ii) extend the maturity of the facility from January 31, 2019, to April 19, 2022, (iii) amend the accordion feature to allow an increase in total commitments from $200 million to $300 million, and (iv) explicitly permit the issuance of the 2024 Notes defined below. All other terms of the 2019 Term Loan remain materially unchanged.

The borrowings under the 2020 Term Loan bear interest at a variable rate per annum equal to either (i) LIBOR plus 150 basis points to 220 basis points, or (ii) a base rate plus 50 basis points to 120 basis points, each depending on our Operating Partnership's leverage ratio. At March 31, 2017, the Operating Partnership’s leverage ratio was 22.4% and the interest rate was LIBOR plus 150 basis points.

2021 Senior Unsecured Term Loan

On February 2, 2016, pursuant to the terms of the Credit Agreement, we partially exercised the accordion feature and entered into a $100 million senior unsecured term loan (the “2021 Term Loan”). The 2021 Term Loan has a five-year term maturing on February 2, 2021. The 2021 Term Loan ranks pari passu with the 2019 Term Loan, the 2020 Term Loan, the 2023 Notes, the 2024 Notes and the Credit Agreement and contains the same financial covenants and other customary restrictive covenants. As of March 31, 2017, we were in compliance with all of the financial covenants under the 2021 Term Loan.

The borrowings under the 2021 Term Loan bear interest at a variable rate per annum equal to either (i) LIBOR plus 150 basis points to 220 basis points, or (ii) a base rate plus 50 basis points to 120 basis points, each depending on our Operating Partnership’s leverage ratio. At March 31, 2017, our Operating Partnership’s leverage ratio was 22.4% and the interest rate was LIBOR plus 150 basis points.

2023 Senior Unsecured Notes

On June 15, 2016, our Operating Partnership issued an aggregate principal amount of $150 million, 4.19% senior unsecured notes due June 15, 2023 (the “2023 Notes”) in a private placement to certain accredited investors. The terms of the 2023 Notes are governed by a note purchase agreement, dated June 15, 2016 (the “2023 Note Purchase Agreement”), by and among our Operating Partnership, the Company and the purchasers named therein.

Interest is payable semiannually, on the 15th day of June and December in each year, commencing on December 15, 2016. The 2023 Notes are senior unsecured obligations of our Operating Partnership and are jointly and severally guaranteed by the Company and each of our Operating Partnership’s subsidiaries that guarantees indebtedness under our Operating Partnership’s Credit Agreement (the “Subsidiary Guarantors”).

Our Operating Partnership may prepay all or a portion of the 2023 Notes upon notice to the holders for 100% of the principal amount so prepaid plus a make-whole premium as set forth in the 2023 Note Purchase Agreement. Upon the occurrence of certain change of control events, holders of the 2023 Notes will have the right to require our Operating Partnership to purchase 100% of such holder’s 2023 Notes in cash at a purchase price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of repurchase.

The 2023 Notes rank pari passu with the 2019 Term Loan, the 2020 Term Loan, the 2021 Term Loan, the 2024 Notes and the Credit Agreement. The 2023 Note Purchase Agreement contains the same financial covenants as the Credit Agreement, as described above. In addition, certain additional financial covenants in the Credit Agreement were automatically incorporated into the 2023 Note Purchase Agreement, and, subject to certain conditions, these additional financial covenants will be deleted, removed, amended or otherwise modified to be more or less restrictive if the analogous covenant in the Credit Agreement is so deleted, removed, amended or otherwise modified. The aforementioned covenants are subject to a number of exceptions and qualifications set forth in the 2023 Note Purchase Agreement. As of March 31, 2017, we were in compliance with all of the financial covenants under the 2023 Note Purchase Agreement.

6. Derivatives and Hedging Activities

On April 9, 2015, we entered into a $75 million forward starting five-year interest rate swap agreement, effective May 5, 2015, to protect against adverse fluctuation in interest rates. The swap reduces our exposure to variability in cash flows relating to interest payments on $75 million of one-month LIBOR variable rate debt and effectively fixes the interest rate at approximately 2.93% per annum. Also, on February 3, 2014, we entered into a five-year interest rate swap agreement that effectively fixes the interest rate on $100 million of outstanding debt at approximately 3.23% per annum. Both interest rate swap agreements were designated for hedge accounting.

On April 21, 2017, we terminated $50 million of our $100 million five-year interest rate swap.

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of our debt funding and the use of derivative financial instruments. Specifically, we enter into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known or uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are used to manage differences in the amount, timing, and duration of our known or expected cash receipts and our known or expected cash payments principally related to our investments and borrowings.

Cash Flow Hedges of Interest Rate Risk

Our objectives in using interest rate derivatives are to reduce variability in interest expense and to manage our exposure to adverse interest rate movements. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income or loss on the condensed consolidated balance sheets and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The amounts recorded in other comprehensive income related to the unrealized loss or gain on derivative contracts were a gain of $0.3 million and a loss of $3.2 million for the three months ended March 31, 2017, and 2016, respectively. The amounts reclassified from other comprehensive income to interest expense on the condensed consolidated statements of operations were $0.3 million and $0.5 million for the three months ended March 31, 2017, and 2016. Any ineffective portion of the change in fair value of the derivatives is recognized directly in net income. During the three months ended March 31, 2017, and 2016, we did not record any amount in net income related to derivatives as there was no hedge ineffectiveness.

Amounts reported in accumulated other comprehensive loss related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the subsequent twelve months, beginning April 1, 2017, we estimate that $0.4 million will be reclassified as an increase to interest expense.

Derivatives are recorded at fair value in our condensed consolidated balance sheets in other assets or unearned revenue, prepaid rent and other liabilities, as applicable. We do not net our derivative position by counterparty for purposes of balance sheet presentation and disclosure. We had $0.1 million and $0.4 million in derivative liabilities recognized in unearned revenue, prepaid rent and other liabilities in our condensed consolidated balance sheets as of March 31, 2017, and December 31, 2016, respectively. We also had a $0.6 million and $0.3 million derivative asset recognized in other assets in our consolidated balance sheets as of March 31, 2017, and December 31, 2016, respectively.

We declared the following dividends per share on our Series A cumulative preferred stock and common stock during the three months ended March 31, 2017:

Dividend covers the period from January 15, 2017, to April 14, 2017.

8. Noncontrolling Interests — Operating Partnership

Noncontrolling interests represent the limited partnership interests in our Operating Partnership held by individuals and entities other than CoreSite Realty Corporation. The current holders of common Operating Partnership units are eligible to have the common Operating Partnership units redeemed for cash or common stock on a one-for-one basis, at our option.

Table of Contents

In connection with the issuance of our 7.25% Series A cumulative redeemable preferred stock on December 12, 2012, our Operating Partnership issued 4,600,000 7.25% Series A cumulative redeemable preferred Operating Partnership units to us. Preferred Operating Partnership units rank senior to the common Operating Partnership units held by both us and noncontrolling interests.

The following table shows the ownership interests in our Operating Partnership as of March 31, 2017, and December 31, 2016:


	March 31, 2017			December 31, 2016
	Number of Units	Percentage of Total		Number of Units	Percentage of Total
CoreSite Realty Corporation	33,764,350	70.9	%	33,376,568	70.7	%
Noncontrolling interests	13,851,347	29.1		13,851,347	29.3
Total	47,615,697	100.0	%	47,227,915	100.0	%

For each share of common stock issued by us, our Operating Partnership issues to us an equivalent common Operating Partnership unit. During the three months ended March 31, 2017, we issued 387,782 shares of common stock related to employee compensation arrangements and therefore an equivalent number of common Operating Partnership units were issued to us by our Operating Partnership.

Holders of common Operating Partnership units of record as of March 31, 2017, received quarterly distributions of $0.80 per unit, payable in correlation with declared dividends on common stock.

The redemption value of the noncontrolling interests at March 31, 2017, was $1.2 billion based on the closing price of the Company’s common stock of $90.05 per share on that date.

9. Equity Incentive Plan

Our Board of Directors adopted and, with the approval of our stockholders, amended the 2010 Equity Award Incentive Plan (as amended, the “2010 Plan”). The 2010 Plan is administered by the Compensation Committee of the Board of Directors. Awards issuable under the 2010 Plan include common stock, stock options, restricted stock, stock appreciation rights, dividend equivalents, Operating Partnership units and other incentive awards. We have reserved a total of 6,000,000 shares of our common stock for issuance pursuant to the 2010 Plan, which may be adjusted for changes in our capitalization and certain corporate transactions. To the extent that an award expires, terminates or lapses, or an award is settled in cash without the delivery of shares of common stock to the participant, then any unvested shares subject to the award will be available for future grant or sale under the 2010 Plan. Shares of restricted stock which are forfeited or repurchased by us pursuant to the 2010 Plan may again be awarded under the 2010 Plan. The payment of dividend equivalents in cash in conjunction with any outstanding awards will not be counted against the shares available for issuance under the 2010 Plan.

As of March 31, 2017, 3,054,224 shares of our common stock were available for issuance pursuant to the 2010 Plan.

Stock Options

Stock option awards are granted with an exercise price equal to the closing market price of the Company’s common stock on the date of grant. The fair value of each option granted under the 2010 Plan is estimated on the date of grant using the Black-Scholes option-pricing model. The fair values are amortized on a straight-line basis over the vesting periods. Stock options have not been granted since the year ending December 31, 2013.

Restricted Awards and Units

Restricted stock awards and restricted stock units, or RSUs, are granted with a fair value equal to the closing market price of the Company’s common stock on the date of grant. The principal difference between restricted stock awards and RSUs is that RSUs are not shares of our common stock and do not have any of the rights or privileges thereof, including voting rights. On the applicable vesting date, the holder of an RSU becomes entitled to a share of common stock. The restricted stock awards and RSUs are amortized on a straight-line basis to expense over the vesting period. The following table sets forth the number of unvested restricted stock awards and RSUs and the weighted-average fair value of these awards at the date of grant:


		Weighted-
	Restricted	Average Fair
	Awards and	Value at Grant
	Units	Date
Unvested balance, December 31, 2016	323,641	$	53.84

Vested	(117,242)		41.33
Unvested balance, March 31, 2017	306,924	$	69.48

As of March 31, 2017, total unearned compensation on restricted awards was approximately $20.0 million, and the weighted-average vesting period was 3.0 years.

Performance Stock Awards

We grant long-term incentives to members of management in the form of performance-based restricted stock awards (“PSAs”) under the 2010 Plan. The number of PSAs earned is based on our achievement of relative total shareholder return (“TSR”) measured versus the MSCI US REIT Index over a three-year performance period and ranges between 0% and 150% of a target number of shares for PSAs granted in 2014 and between 25% and 175% of the target number of shares for PSAs granted in 2015, 2016, and 2017. The PSAs are granted at the maximum percentage of target and are retired annually to the extent we do not achieve maximum relative TSR versus the MSCI US REIT Index. The PSAs are

Table of Contents

earned upon TSR achievement measured both annually and over the full three-year performance period. The PSAs have a service condition and will be released at the end of the three-year performance period, to the extent earned, provided that the holder continues to be employed by the Company at the end of the three-year performance period. The PSAs are amortized on a straight-line basis to expense over the vesting period. Holders of the PSAs are entitled to dividends on the PSAs, which will be accrued and paid in cash at the end of the three-year performance period.

The following table sets forth the number of unvested PSAs and the weighted-average fair value of these awards at the date of grant:


				Weighted-

(1)

Includes the annual adjustment for the number of PSAs earned based on our achievement of relative TSR measured versus the MSCI US REIT Index for the applicable performance periods.

As of March 31, 2017, total unearned compensation on PSAs was approximately $5.1 million, and the weighted-average vesting period was 2.5 years. The fair value of each PSA award is estimated on the date of grant using a Monte Carlo simulation. The simulation requires assumptions for expected volatility, risk-free rate of return, and dividend yield. The following table summarizes the assumptions used to value the PSAs granted during the three months ended March 31, 2017, and 2016.


	Three Months Ended March 31,

Expected annual dividend(1)	—		—
Risk-free rate	1.60	%	0.97	%

The fair value of the PSAs assumes reinvestment of dividends.

10. Earnings Per Share

Basic net income per share is calculated by dividing the net income attributable to common shares by the weighted-average number of common shares outstanding during the period. Diluted net income per share adjusts basic net income per share for the effects of potentially dilutive common shares, if the effect is not antidilutive. Potentially dilutive common stock consists of shares issuable under the 2010 Plan. The following is a summary of basic and diluted net income per share (in thousands, except share and per share amounts):


	Three Months Ended March 31,
	2017		2016
Net income attributable to common shares	$	16,292	$	11,261
Weighted-average common shares outstanding - basic		33,558,787		30,252,693
Effect of potentially dilutive common shares:
Stock options		156,035		200,379
Unvested awards		266,954		241,675
Weighted-average common shares outstanding - diluted		33,981,776		30,694,747
Net income per share attributable to common shares
Basic	$	0.49	$	0.37
Diluted	$	0.48	$	0.37

In the calculations above, we have excluded weighted-average potentially dilutive securities of 39,937 and 59,408 for the three months ended March 31, 2017, and 2016, respectively, as their effect would have been antidilutive.

11. Estimated Fair Value of Financial Instruments

Authoritative guidance issued by FASB establishes a hierarchy of valuation techniques based on the observability of inputs utilized in measuring assets and liabilities at fair values. This hierarchy establishes market-based or observable inputs as the preferred source of values, followed by valuation models using management assumptions in the absence of market inputs. The three levels of the hierarchy under the authoritative guidance are as follows:

Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the assessment date.

Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 — Unobservable inputs for the asset or liability.

Our financial instruments consist of cash and cash equivalents, accounts and other receivables, interest rate swaps, the revolving credit facility, the senior unsecured term loans, senior unsecured notes, interest payable and accounts payable. The carrying values of cash and cash equivalents, accounts and other receivables, interest payable and accounts payable approximate fair values due to the short-term nature of these financial instruments. The interest rate swaps are recorded at fair value.

The valuation of our derivatives is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative, which reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. We have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy; however, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by our Operating Partnership and its counterparties. As of March 31, 2017, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustment is not significant to the overall valuation of our derivative portfolio. As a result we classify our derivative valuation in Level 2 of the fair value hierarchy.

The total principal balance of our revolving credit facility, senior unsecured term loans, and senior unsecured notes was $723.0 million and $694.0 million as of March 31, 2017, and December 31, 2016, respectively, with a fair value of $725.8 million and $673.0 million, respectively, based on Level 3 inputs from the fair value hierarchy. Under the discounted cash flow method, the fair values of the revolving credit facility and the senior unsecured term loans are based on our assumptions of market interest rates and terms available incorporating our credit risk for similar loan maturities.

12. Commitments and Contingencies

Our properties require periodic investments of capital for general capital improvements and for tenant-related capital expenditures. We enter into various construction and equipment contracts with third parties for the development of our properties. At March 31, 2017, we had open commitments related to construction contracts of approximately $16.3 million.

Additionally, we have commitments related to telecommunications capacity used to connect data centers located within the same market or geographical area, power usage, and company-wide improvements that are ancillary to revenue generation. At March 31, 2017, we had open commitments related to these contracts of approximately $10.4 million.

We entered into a Memorandum of Understanding with the Virginia Economic Development Partnership Authority (the “Virginia Memorandum of Understanding”) pursuant to which we are afforded the opportunity to benefit from an exemption from sales and use tax for certain qualifying data center related purchases and equipment leases. This exemption also extends to our customers who execute a Landlord-Tenant Participation Agreement under the Virginia Memorandum of Understanding. The Virginia Memorandum of Understanding establishes thresholds relating to the level of capital investment and qualifying new jobs created within the Commonwealth of Virginia by us and our customers who have agreed to sign participation agreements. In the event those thresholds are not met as of the agreed upon performance date of June 1, 2017, we would be required to repay the sales and use tax benefit we have received, as

Table of Contents

well as any tax benefit received by our customers who default on their obligation to repay the tax benefit they have received under the exemption program up to a maximum of $7.5 million. We estimate that we may be required to repay between $0.0 million and $4.0 million for sales and use tax benefits we have received under the exemption program, of which none has been accrued in accounts payable and accrued expenses in our condensed consolidated balance sheets as of March 31, 2017, and December 31, 2016, as we believe we will meet the thresholds as of the June 1, 2017, performance date.

In the ordinary course of business, we are subject to claims and administrative proceedings. Except as described below, we are not presently party to any proceeding, which we believe to be material or which we would expect to have, individually or in the aggregate, a material adverse effect on our business, financial condition, cash flows or results of operations.

On February 4, 2014, U.S. Colo, LLC (“U.S. Colo”), a current customer, filed a complaint against us in the United States District Court for the Central District of California. In the complaint, U.S. Colo alleged that it should not have been charged for the use of various interconnection services under the terms of an existing agreement between the parties.

On July 23, 2015, after amendments to the complaint, dismissal of several of U.S. Colo’s claims, and a remand of the case to the Superior Court of the State of California, County of Los Angeles (the “Superior Court”), U.S. Colo filed an amended complaint alleging breach of contract and breach of the covenant of good faith and fair dealing. The amended complaint seeks $802,564 in damages for charges paid to us for interconnection services; $70,080,000 in damages for alleged losses of revenue and profits; attorney’s fees, interest, and costs of the suit; and declaratory and injunctive relief.

On February 4, 2016, the Superior Court granted our motion for summary adjudication, finding that U.S. Colo had contractually waived all claims for lost revenue or profits or other consequential damages.

The case was set to start trial on August 29, 2016, but upon unopposed application, the Superior Court vacated the August 29, 2016, trial date, continued the trial date to July 24, 2017, set a final status conference for July 14, 2017, and reset other procedural deadlines in the action. On April 7, 2017, US Colo filed another unopposed application to further continue the trial date. We intend to vigorously defend this legal proceeding.

On July 9, 2015, a purported class action lawsuit was filed in the Superior Court of the State of California, County of Los Angeles, against us, alleging various employment law violations related to overtime, meal and break periods, minimum wage, timely payment of wages, wage statements, payroll records and business expenses. On March 15, 2016, we filed a responsive pleading generally denying the allegations. On July 27, 2016, the parties entered into a Memorandum of Understanding, pursuant to which the parties agreed to settle the lawsuit. The settlement, which remains subject to Superior Court approval, resolves the matter on a class-wide basis, on behalf of all non-exempt employees in California, as well a related class action lawsuit filed on July 22, 2016, alleging similar claims, in exchange for a $600,000 payment to be made by us. A hearing for Superior Court approval of the settlement has been scheduled for June 5, 2017. There can be no assurance that the settlement will be finally approved by the Superior Court. We intend to vigorously defend this legal proceeding if the settlement is not approved.

While it is not feasible to predict or determine the outcome of these legal proceedings, as of March 31, 2017, we estimate that the ultimate resolution of these litigation matters and other disputes could result in a loss that is reasonably possible between $0.6 million and $3.1 million in the aggregate, of which $2.9 million has been accrued in accounts payable and accrued expenses in our consolidated balance sheet as of March 31, 2017.

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

Forward-Looking Statements

This Quarterly Report on Form 10-Q (this “Quarterly Report”), together with other statements and information publicly disseminated by our company, contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 (“PSLRA”), namely Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the PSLRA and include this statement for purposes of complying with these safe harbor provisions.

In particular, statements pertaining to our capital resources, portfolio performance, business strategies and results of operations contain forward-looking statements. You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “intends,” “plans,” “pro forma” or “anticipates” or the negative of these words and phrases or similar words or phrases that are predictions of or indicate future events or trends and that do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or intentions. Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance, which may be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. 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: (i) the geographic concentration of our data centers in certain markets and any adverse developments in local economic conditions or the demand for data center space in these markets; (ii) fluctuations in interest rates and increased operating costs; (iii) difficulties in identifying properties to acquire and completing acquisitions; (iv) the significant competition in our industry and an inability to lease vacant space, renew existing leases or release space as leases expire; (v) lack of sufficient customer demand to realize expected returns on our investments to expand our property portfolio; (vi) decreased revenue from costs and disruptions associated with any failure of our physical infrastructure or services; (vii) our ability to lease available space to existing or new customers; (viii) our failure to obtain necessary outside financing; (ix) our ability to service existing debt; (x) our failure to qualify or maintain our status as a REIT; (xi) financial market fluctuations; (xii) changes in real estate and zoning laws and increases in real estate taxes; (xiii) delays or disruptions in third-party network connectivity; (xiv) service failures or price increases by third party power suppliers; (xv) inability to renew net leases on the data center properties we lease; and (xvi) other factors affecting the real estate or technology industries generally.

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, except as required by applicable law. The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance, including factors and risks included in other sections of this Quarterly Report. Additional information concerning these and other risks and uncertainties is contained in our other periodic filings with the United States Securities and Exchange Commission (“SEC”) pursuant to the Exchange Act. We discussed a number of material risks in Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2016. Those risks continue to be relevant to our performance and financial condition. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

Overview

Unless the context requires otherwise, references in this Quarterly Report to “we,” “our,” “us” and “our company” refer to CoreSite Realty Corporation, a Maryland corporation, together with our consolidated subsidiaries, including CoreSite, L.P., a Delaware limited partnership of which we are the sole general partner and to which we refer in this Quarterly Report as our “Operating Partnership.”

We are engaged in the business of ownership, acquisition, construction and operation of strategically located data centers in some of the largest and fastest growing data center markets in the United States, including the Northern Virginia (including Washington D.C.), New York and San Francisco Bay areas, Chicago, Los Angeles, Boston, Miami, and Denver.

Table of Contents

We deliver secure, reliable, high-performance data center and interconnection solutions to a growing customer ecosystem across eight key North American markets. More than 1,000 of the world’s leading enterprises, network operators, cloud providers, and supporting service providers choose us to connect, protect and optimize their performance-sensitive data, applications and computing workloads.

Our focus is to bring together a network and cloud community to support the needs of enterprises, and create a diverse customer ecosystem. Our growth strategy includes (i) increasing cash flow from in-place data center space, (ii) capitalizing on embedded expansion opportunities within existing data centers, (iii) selectively pursuing acquisition and development opportunities in existing and new markets, (iv) expanding existing customer relationships, and (v) attracting new customers.

Our Portfolio

As of March 31, 2017, our property portfolio included 20 operating data center facilities, office and light-industrial space and multiple potential development projects that collectively comprise over 3.5 million net rentable square feet (“NRSF”), of which over 2.2 million NRSF is existing data center space. The approximately 1.0 million NRSF of development projects includes space available for development and construction of new data center facilities. We expect that this development potential plus any incremental investment into existing or new markets will enable us to accommodate existing and future customer demand and position us to continue to increase our operating cash flows. The following table provides an overview of our property portfolio as of March 31, 2017:

Represents NRSF at each operating facility that is currently occupied or readily available for lease as data center space and pre-stabilized data center space. Both occupied and available data center NRSF includes a factor based on management’s estimate to account for a customer’s proportionate share of the required data center support space

Table of Contents

(such as the mechanical, telecommunications and utility rooms) and building common areas, which may be updated on a periodic basis to reflect the most current build-out of our properties. Operating data center NRSF may require investment of Deferred Expansion Capital (see definition on page 29).

(2)

Pre-stabilized NRSF represents projects or facilities that recently have been developed and are in the initial lease-up phase. Pre-stabilized projects or facilities become stabilized operating properties at the earlier of achievement of 85% occupancy or 24 months after development completion.

(3)

Represents incremental data center capacity currently vacant in existing facilities in our portfolio that requires significant capital investment in order to develop into data center facilities. Includes NRSF under construction for which substantial activities are ongoing to prepare the property for its intended use following development. The NRSF reflects management’s estimate of engineering drawings and required support space and is subject to change based on final demising of space.

(4)

Represents the monthly contractual rent under existing commenced customer leases as of March 31, 2017, multiplied by 12. This amount reflects total annualized base rent before any one-time or non-recurring rent abatements and excludes power revenue, interconnection revenue and operating expense reimbursement. On a gross basis, our total portfolio annualized rent was approximately $260.1 million as of March 31, 2017, which includes $6.9 million in operating expense reimbursements under modified gross and triple-net leases. See footnote (6) below for more information regarding annualized rent for the Santa Clara campus.

(5)

Includes customer leases that have commenced and are occupied as of March 31, 2017. The percent occupied is determined based on occupied square feet as a proportion of total operating NRSF as of March 31, 2017. The percent occupied for stabilized data center space would have been 95.0%, rather than 94.7%, if all leases signed in the current and prior periods had commenced. The percent occupied for our total portfolio, including stabilized data center space, pre-stabilized space and office and light-industrial space, would have been 89.1%, rather than 87.8% if all leases signed in current and prior periods had commenced.

(6)

The annualized rent for the Santa Clara campus includes amounts associated with a restructured lease agreement involving a customer that has vacated its leased space and is paying discounted rent payments that may be applied to new lease arrangements elsewhere in our portfolio on a dollar-for-dollar basis until the original lease term expires. The $4.1 million payable pursuant to this agreement is scheduled to expire in the second quarter of 2017.

(7)

Represents space that is currently occupied or readily available for lease as space other than data center space, which typically is offered for office or light-industrial uses.

(8)

Based upon our expectations regarding entitlements for the Reston Campus Expansion, we may build approximately 611,000 NRSF of incremental data center capacity across multiple phases. Currently, 178,712 NRSF and 48,928 NRSF is operating office and light-industrial space and powered shell data center space, respectively. In the second quarter of 2017, a customer is scheduled to vacate its 28,337 NRSF office lease, which will result in a decrease of $0.8 million to annualized rent. This office space will not be re-leased based on our development plans.

In addition to our development opportunities disclosed within this table, we have entitled and unentitled land adjacent to our NY2 and LA2 facilities, in the form of existing parking lots. By utilizing existing parking lots, we believe that we could develop 100,000 NRSF and 200,000 NRSF buildings at NY2 and LA2, respectively, upon receipt of necessary entitlements.

Capital Expenditures

The following table sets forth information regarding capital expenditures during the three months ended March 31, 2017 (in thousands):


	Three Months Ended
	March 31, 2017
Data center expansion	$	22,644
Non-recurring investments		3,301
Tenant improvements		1,848
Recurring capital expenditures		2,582
Total capital expenditures	$	30,375

During the three months ended March 31, 2017, we incurred approximately $30.4 million of capital expenditures, of which approximately $22.6 million related to data center expansion activities, including new data center construction, the development of capacity within existing data centers and other revenue generating investments. As we construct data center capacity, we work to optimize both the amount of the capital we deploy on power and cooling infrastructure and the timing of that capital deployment; as such, we generally construct our power and cooling infrastructure supporting

our data center NRSF based on our estimate of customer utilization. This practice can result in our investment at a later time in “Deferred Expansion Capital”. We define Deferred Expansion Capital as our estimate of the incremental capital we may invest in the future to add power or cooling infrastructure to support existing or anticipated future customer utilization of NRSF within our operating data centers.

During the three months ended March 31, 2017, we completed development of one computer room placed into service at LA2. The following table sets forth capital expenditures spent on data center NRSF placed into service during the three months ended March 31, 2017, or under construction as of March 31, 2017:


			NRSF
	Data Center		Placed into	Under

Other		8,265	—	41,385
Total	$	22,644	4,726	116,212

During the three months ended March 31, 2017, we incurred approximately $3.3 million in non-recurring investments, of which $2.2 million is a result of internal IT software development and the remaining $1.1 million is a result of other non-recurring investments, such as remodel or upgrade projects.

During the three months ended March 31, 2017, we incurred approximately $1.8 million in tenant improvements, which relates to numerous small tenant improvement projects at various properties.

During the three months ended March 31, 2017, we incurred approximately $2.6 million of recurring capital expenditures within our portfolio for required equipment upgrades that have a future economic benefit.

Factors that May Influence our Results of Operations

A complete discussion of factors that may influence our results of operations can be found in our Annual Report on Form 10-K for the year ended December 31, 2016, filed with the SEC on February 10, 2017, which is accessible on the SEC’s website at www.sec.gov.

Our ability to re-lease expiring space at rental rates equal to or in excess of current rental rates will impact our results of operations. In addition to approximately 336,000 NRSF of data center and office and light-industrial space currently unoccupied in our total portfolio, 815 and 706 data center leases representing approximately 13.0% and 14.3% of the NRSF in our operating data center portfolio with current average annualized rental rates of $152 per NRSF and $152 per NRSF are scheduled to expire during the remainder of 2017 and the year ending December 31, 2018, respectively.

The amount of revenue generated by the properties in our portfolio depends on several factors, including our ability to maintain or improve the occupancy rates of currently leased space and to lease currently available space. As of March 31, 2017, we had approximately 262,000 NRSF of unoccupied data center space of which approximately 35,000 NRSF is leased with a future commencement date. The loss of one or more significant customers could have a material adverse effect on our results of operations. During the three months ended March 31, 2017, we entered into new and expansion

Total operating revenues	$	114,921	$	92,480	$	22,441	24.3	%

A majority of the increase in operating revenues was due to a $19.2 million increase in data center rental and power revenue during the three months ended March 31, 2017, compared to the 2016 period. The increase in data center rental and power revenue is due primarily to the commencement of new and expansion leases of approximately 435,000 NRSF at an average rental rate of $139 per NRSF during the twelve months ended March 31, 2017. The increase in operating revenues was also attributable to the renewal of approximately 294,000 NRSF at a rent growth rate of 6.6% and the

Table of Contents

acquisition of the Reston Campus expansion during twelve months ended March 31, 2017. This increase was partially offset by the move-out of customer leases totaling approximately 69,000 NRSF at an average rental rate of $186 per NRSF during the twelve months ended March 31, 2017.

In addition, interconnection revenue increased $1.8 million, or 13.9%, during the three months ended March 31, 2017, compared to the 2016 period, primarily as a result of an increase in the volume of cross connects from new and existing customers. During the twelve months ended March 31, 2017, total cross connect volume grew 10.3%.

Operating Expenses

Operating expenses during the three months ended March 31, 2017, and 2016, were as follows (in thousands):

Transaction costs		—		3		(3)	(100.0)
Total operating expenses	$	84,657	$	70,859	$	13,798	19.5	%

Property operating and maintenance expense increased $4.6 million, or 18.5%, primarily as a result of an increase in power expense due to increased customer consumption as a result of the commencement of new and expansion leases during the twelve months ended March 31, 2017, that resulted in a 30.7% increase in occupied data center NRSF from 1,503,235 NRSF as of March 31, 2016, to 1,965,323 NRSF as of March 31, 2017. In addition, payroll and benefits expense increased due to an increase in facilities and operations headcount associated with increased occupied data center NRSF.

Real estate taxes and insurance increased $1.4 million, or 46.9%, during the three months ended March 31, 2017, compared to the 2016 period, primarily as a result of decreased capitalized real estate taxes due to SV6, SV7, and computer rooms at LA2 and VA2 being placed into service and increased tax assessments at our Los Angeles properties. We also realized real estate tax expense related to our Reston Campus Expansion, which we did not own during the three months ended March 31, 2016.

Depreciation and amortization expense increased $7.6 million during the three months ended March 31, 2017, compared to the 2016 period, as a result of an increase in depreciation expense from approximately 460,000 NRSF of new data center expansion projects placed into service with a cost basis of approximately $319.5 million.

Interest Expense

Interest expense increased $3.1 million during the three months ended March 31, 2017, compared to the 2016 period, primarily as a result of the increase in overall debt outstanding during the three months ended March 31, 2017. The total principal debt outstanding was $723.0 million and $461.0 million as of March 31, 2017, and 2016, respectively. A summary of interest expense for the three months ended March 31, 2017, and 2016, is as follows (in thousands):

Liquidity and Capital Resources

Discussion of Cash Flows

Three Months Ended March 31, 2017, Compared to Three Months Ended March 31, 2016

Net cash provided by operating activities was $50.9 million for the three months ended March 31, 2017, compared to $26.3 million for the three months ended March 31, 2016. The increase of $24.6 million, or 93% was primarily due to the commencement of new and expansion leases of approximately 435,000 NRSF at an average rental rate of $139 per NRSF, the renewal of approximately 294,000 NRSF at a rent growth rate of 6.6%, and growth in cash receipts from data center rental, power and interconnection services from existing customers.

Net cash used in investing activities decreased by $26.2 million, or 37%, to $45.2 million for the three months ended March 31, 2017, compared to $71.4 million for the three months ended March 31, 2016. This decrease was due primarily to construction spend on our SV6 and SV7 properties at our Santa Clara campus during the three months ended March 31, 2016.

Net cash used in financing activities was $7.8 million for the three months ended March 31, 2017, compared to $41.4 million provided by financing activities for the three months ended March 31, 2016. The $49.2 million change in financing activities was primarily a result of net cash proceeds from the revolving credit facility of $29.0 million during the three months ended March 31, 2017, compared to cash proceeds from the 2021 Term Loan of $100 million and net cash payments on the revolving credit facility of $31.3 million during the three months ended March 31, 2016. There was also an increase of $13.6 million in dividends and distributions paid on our common stock and Operating Partnership units during the three months ended March 31, 2017, as a result of an increase in the quarterly dividend from $0.53 per share or unit paid during the three months ended March 31, 2016, to $0.80 per share or unit paid during the three months ended March 31, 2017.

Analysis of Liquidity and Capital Resources

We have an effective shelf registration statement that allows us to offer for sale various unspecified classes of equity and debt securities. As circumstances warrant, we may issue debt and/or equity securities from time to time on an opportunistic basis, dependent upon market conditions and available pricing. We make no assurance that we can issue and sell such securities on acceptable terms or at all.

Our short-term liquidity requirements primarily consist of funds needed for interest expense, operating costs including utilities, site maintenance costs, real estate and personal property taxes, insurance, rental expenses, sales and marketing and general and administrative expenses, certain capital expenditures, including for the development of data center space and future distributions to common and preferred stockholders and holders of our common Operating Partnership units during the next twelve months. As of March 31, 2017, we had $2.4 million of cash and cash equivalents. Subject to our ability to obtain capital upon favorable terms, we estimate our anticipated development activity over the next twelve months will require approximately $230 million to $250 million of capital investment to expand our operating data center portfolio.

Turn-Key Data Center (“TKD”) estimated development costs includes two components: (1) general construction to ready the NRSF as data center space and (2) power, cooling and other infrastructure to provide the designed amount of power capacity for the project. Following development completion, incremental capital, referred to as Deferred Expansion Capital, may be invested to support existing or anticipated future customer utilization of NRSF within our operating data centers.

(2)

Includes a portion of the cost of infrastructure to support later phases of the development.

We expect to meet our short-term liquidity requirements, including our anticipated development activity over the next twelve months, through net cash provided by operations and by incurring additional indebtedness.

In June 2015, our Operating Partnership and certain subsidiary co-borrowers entered into a third amended and restated credit agreement (the “Credit Agreement”), which provides a total commitment of $600.0 million, including a $350.0 million revolving credit facility and $250.0 million of term loans. The total amount available for borrowing under our revolving credit facility is equal to the lesser of $350.0 million or the availability calculated on our unencumbered asset pool. As of March 31, 2017, $223.0 million was borrowed and outstanding, $4.5 million was outstanding under letters of credit and therefore $122.5 million remained available for us to borrow under our revolving credit facility. Our Credit Agreement contains an accordion feature which allows our Operating Partnership to increase the total commitment by $200.0 million under specified circumstances, including securing capital from new or existing lenders. Our indebtedness maturity schedule is summarized below.

On April 19, 2017, our Operating Partnership and certain subsidiaries amended our $100 million senior unsecured term loan entered into in January 2014 (the “2019 Term Loan”) to (i) exercise the accordion feature to increase the total commitments to $200 million and (ii) extend the maturity of the facility from January 31, 2019, to April 19, 2022. Additionally, on April 20, 2017, our Operating Partnership issued an aggregate principal amount of $175 million, 3.91% senior unsecured notes due April 20, 2024 (the “2024 Notes”) in a private placement to certain accredited investors. The proceeds from these two transactions were used to pay down the revolving credit facility and increase our short-term liquidity. Including the subsequent repayment of the revolving credit facility, we have the ability to borrow approximately $345.5 million under the revolving credit facility. Refer to Item 1. Financial Statements — Note 5 — Debt for additional information.

Our long-term liquidity requirements primarily consist of the costs to fund the Reston Campus Expansion, Deferred Expansion Capital, additional phases of our current projects under construction, future development of other space in our portfolio not currently scheduled, property acquisitions, future distributions to common and preferred stockholders and holders of our common Operating Partnership units, scheduled debt maturities and other capital expenditures. We expect to meet our long-term liquidity requirements through net cash provided by operations, after payment of dividends, and by incurring long-term indebtedness, such as drawing on our revolving credit facility, exercising our senior unsecured

term loan accordion features or entering into new debt agreements with our bank group or certain accredited investors. We also may raise capital in the future through the issuance of additional equity or debt securities, subject to prevailing market conditions, and/or through the issuance of common Operating Partnership units. However, there is no assurance that we will be able to successfully raise additional capital on acceptable terms or at all.

Financial Statements — Note 5 — Debt.

Funds From Operations

We consider funds from operations (“FFO”), a non-GAAP measure, to be a supplemental measure of our performance which should be considered along with, but not as an alternative to, net income 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”). NAREIT defined FFO represents net income (computed in accordance with GAAP), excluding gains (or losses) from sales of property and undepreciated land and impairment write-downs of depreciable real estate, plus real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. FFO attributable to common shares and units represents FFO less preferred stock dividends declared during the period.

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.

We offer this measure because we recognize that FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes real estate related depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. FFO is a non-GAAP measure and should not be considered a measure of liquidity, an alternative to net income, 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 pay dividends or make distributions. In addition, our calculations of FFO are not necessarily comparable to FFO as calculated by other REITs that do not use the same definition or implementation guidelines or interpret the NAREIT standards differently from us. Investors in our securities should not rely on these

measures as a substitute for any GAAP measure, including net income. The following table provides a reconciliation of our net income to FFO:


	Three Months Ended March 31,
(in thousands)	2017		2016
Net income	$	25,060	$	19,606
Real estate depreciation and amortization		31,029		23,385
FFO		56,089		42,991
Preferred stock dividends		(2,084)		(2,084)
FFO attributable to common shares and units	$	54,005	$	40,907
FFO per common share and OP unit - diluted	$	1.13	$	0.86

Distribution Policy

In order to comply with the REIT requirements of the Internal Revenue Code of 1986, as amended (the “Code”), we are generally required to make annual distributions to our stockholders of at least 90% of our net taxable income. Our common share distribution policy is to distribute a percentage of our cash flow to ensure that we will, at a minimum, meet the distribution requirements of the Code while considering other cash requirements, such as capital improvements, investment activities and other capital needs.

We have made distributions every quarter since our initial public offering. During the three months ended March 31, 2017, we declared a dividend of $0.80 per common share and Operating Partnership Unit as of March 31, 2017. While we plan to continue to make quarterly distributions, no assurances can be made as to the frequency or amounts of any future distributions. The payment of common share distributions is dependent upon our financial condition, operating results and REIT distribution requirements and may be adjusted at the discretion of our Board of Directors during the year.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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. Our future income, cash flows and fair values relevant to financial instruments are dependent upon prevalent market interest rates. 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, 2017, we had $573.0 million of consolidated principal debt outstanding that bore variable interest based on one month LIBOR. As of March 31, 2017, we have two interest rate swap agreements in place to fix the interest rate on $175.0 million of our one month LIBOR variable rate debt. Our interest rate risk not covered by an interest rate swap agreement is $398.0 million of variable rate debt outstanding as of March 31, 2017. See additional discussion in Item 1. Financial Statements — Note 6 — Derivatives and Hedging Activities.

We monitor our market interest rate risk exposures using a sensitivity analysis. Our sensitivity analysis estimates the exposure to market interest rate risk sensitive instruments assuming a hypothetical 1% change in interest rates on our $398.0 million unhedged variable rate debt. If interest rates were to increase or decrease by 1%, the corresponding increase or decrease, as applicable, in interest expense on our variable rate debt would increase or decrease, as applicable, future earnings and cash flows by approximately $4.0 million per year.

These analyses do not consider the effect of any change in overall economic activity that could impact interest rates. Further, in the event of an increase in interest rates of significant 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

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed in our reports under the Exchange Act is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and regulations and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As of March 31, 2017, we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and our Chief Financial Officer, regarding the effectiveness of our disclosure controls and procedures. Based on the foregoing, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2017.

Changes in Internal Control over Financial Reporting

During the three months ended March 31, 2017, we implemented certain billing and procurement components of our new accounting and financial reporting information technology system. There were no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15(d)-15(f) under the Exchange Act) that occurred during the three months ended March 31, 2017, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION
