EXPLANATORY NOTE
This report combines the quarterly reports on Form 10-Q for the quarter ended September 30, 2018 of Digital Realty Trust, Inc., a Maryland corporation, and Digital Realty Trust, L.P., a Maryland limited partnership, of which Digital Realty Trust, Inc. is the sole general partner. Unless otherwise indicated or unless the context requires otherwise, all references in this report to “we,” “us,” “our,” “our Company” or “the Company” refer to Digital Realty Trust, Inc. together with its consolidated subsidiaries, including Digital Realty Trust, L.P. Unless otherwise indicated or unless the context requires otherwise, all references to “our Operating Partnership” or “the Operating Partnership” refer to Digital Realty Trust, L.P. together with its consolidated subsidiaries.
Digital Realty Trust, Inc. is a real estate investment trust, or REIT, and the sole general partner of Digital Realty Trust, L.P. As of September 30, 2018, Digital Realty Trust, Inc. owned an approximate 96.1% common general partnership interest in Digital Realty Trust, L.P. The remaining approximate 3.9% of the common limited partnership interests of Digital Realty Trust, L.P. are owned by non-affiliated third parties and certain directors and officers of Digital Realty Trust, Inc. As of September 30, 2018, Digital Realty Trust, Inc. owned all of the preferred limited partnership interests of Digital Realty Trust, L.P. As the sole general partner of Digital Realty Trust, L.P., Digital Realty Trust, Inc. has the full, exclusive and complete responsibility for the Operating Partnership’s day-to-day management and control.

We believe combining the quarterly reports on Form 10-Q of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. into this single report results in the following benefits:

enhancing investors’ understanding of our Company and our Operating Partnership by enabling investors to view the business as a whole in the same manner as management views and operates the business;

eliminating duplicative disclosure and providing a more streamlined and readable presentation since a substantial portion of the disclosure applies to both our Company and our Operating Partnership; and

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

There are a few differences between our Company and our Operating Partnership, which are reflected in the disclosure in this report. We believe it is important to understand the differences between our Company and our Operating Partnership in the context of how we operate as an interrelated consolidated company. Digital Realty Trust, Inc. is a REIT, whose only material asset is its ownership of partnership interests of Digital Realty Trust, L.P. As a result, Digital Realty Trust, Inc. does not conduct business itself, other than acting as the sole general partner of Digital Realty Trust, L.P., issuing public equity from time to time and guaranteeing certain unsecured debt of Digital Realty Trust, L.P. and certain of its subsidiaries and affiliates. Digital Realty Trust, Inc. itself does not issue any indebtedness but guarantees the unsecured debt of Digital Realty Trust, L.P. and certain of its subsidiaries and affiliates, as disclosed in this report. Digital Realty Trust, L.P. holds substantially all the assets of the Company and holds the ownership interests in the Company’s joint ventures. Digital Realty Trust, L.P. conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from public equity issuances by Digital Realty Trust, Inc., which are generally contributed to Digital Realty Trust, L.P. in exchange for partnership units, Digital Realty Trust, L.P. generates the capital required by the Company’s business through Digital Realty Trust, L.P.’s operations, by Digital Realty Trust, L.P.’s direct or indirect incurrence of indebtedness or through the issuance of partnership units.
The presentation of noncontrolling interests in operating partnership, stockholders’ equity and partners’ capital are the main areas of difference between the condensed consolidated financial statements of Digital Realty Trust, Inc. and those of Digital Realty Trust, L.P. The common limited partnership interests held by the limited partners in Digital Realty Trust, L.P. are presented as limited partners’ capital within partners’ capital in Digital Realty Trust, L.P.’s condensed consolidated financial statements and as noncontrolling interests in operating partnership within equity in Digital Realty Trust, Inc.’s condensed consolidated financial statements. The common and preferred partnership interests held by Digital Realty Trust, Inc. in Digital Realty Trust, L.P. are presented as general partner’s capital within partners’ capital in Digital Realty Trust, L.P.’s condensed consolidated financial statements and as preferred stock, common stock, additional paid-in capital and accumulated dividends in excess of earnings within stockholders’ equity in Digital Realty Trust, Inc.’s condensed consolidated financial statements. The differences in the presentations between stockholders’ equity and partners’ capital result from the differences in the equity issued at the Digital Realty Trust, Inc. and the Digital Realty Trust, L.P. levels.

To help investors understand the significant differences between the Company and the Operating Partnership, this report presents the following separate sections for each of the Company and the Operating Partnership:

Condensed consolidated financial statements;

the following notes to the condensed consolidated financial statements:

"Debt of the Company" and "Debt of the Operating Partnership";

"Income per Share" and "Income per Unit"; and

"Equity and Accumulated Other Comprehensive Loss, Net" and "Capital and Accumulated Other Comprehensive Loss";

Part I, Item 2. "Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources of the Parent Company" and "—Liquidity and Capital Resources of the Operating Partnership"; and

Part II, Item 2. "Unregistered Sales of Equity Securities and Use of Proceeds".
This report also includes separate Part I, Item 4. "Controls and Procedures" sections and separate Exhibit 31 and 32 certifications for each of the Company and the Operating Partnership in order to establish that the Chief Executive Officer and the Chief Financial Officer of each entity during the period covered by this report have made the requisite certifications and that the Company and the Operating Partnership are compliant with Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934 and 18 U.S.C. §1350.
In order to highlight the differences between the Company and the Operating Partnership, the separate sections in this report for the Company and the Operating Partnership specifically refer to the Company and the Operating Partnership. In the sections that combine disclosure of the Company and the Operating Partnership, this report refers to actions or holdings as being actions or holdings of the Company. Although the Operating Partnership is generally the entity that enters into contracts and joint ventures and holds assets and debt, reference to the Company is appropriate because the business is one enterprise and the Company operates the business through the Operating Partnership.

As general partner with control of the Operating Partnership, Digital Realty Trust, Inc. consolidates the Operating Partnership for financial reporting purposes, and it does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. are the same on their respective condensed consolidated financial statements. The separate discussions of Digital Realty Trust, Inc. and Digital Realty Trust, L.P. in this report should be read in conjunction with each other to understand the results of the Company on a consolidated basis and how management operates the Company.

2. Summary of Significant Accounting Policies
(a) Principles of Consolidation and Basis of Presentation
The accompanying interim condensed consolidated financial statements include all of the accounts of Digital Realty Trust, Inc., the Operating Partnership and the subsidiaries of the Operating Partnership. Intercompany balances and transactions have been eliminated.
The accompanying interim condensed consolidated financial statements are unaudited, but have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) for interim financial information and in compliance with the rules and regulations of the United States Securities and Exchange Commission. Accordingly, they do not include all of the disclosures required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments necessary for a fair presentation have been included. All such adjustments are considered to be of a normal recurring nature, except as otherwise indicated. The results of operations for the interim periods are not necessarily indicative of the results to be obtained for the full fiscal year. These 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, 2017.
The notes to the condensed consolidated financial statements of Digital Realty Trust, Inc. and the Operating Partnership have been combined to provide the following benefits:
enhancing investors’ understanding of the Company and the Operating Partnership by enabling investors to view the business as a whole in the same manner as management views and operates the business;
eliminating duplicative disclosure and providing a more streamlined and readable presentation since a substantial portion of the disclosure applies to both the Company and the Operating Partnership; and
creating time and cost efficiencies through the preparation of one set of notes instead of two separate sets of notes.

There are a few differences between the Company and the Operating Partnership, which are reflected in these condensed consolidated financial statements. We believe it is important to understand the differences between the Company and the Operating Partnership in the context of how we operate as an interrelated consolidated company. Digital Realty Trust, Inc.’s only material asset is its ownership of partnership interests of the Operating Partnership. As a result, Digital Realty Trust, Inc. generally does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing public securities from time to time and guaranteeing certain unsecured debt of the Operating Partnership and certain of its subsidiaries and affiliates. Digital Realty Trust, Inc. itself has not issued any indebtedness but guarantees the unsecured debt of the Operating Partnership and certain of its subsidiaries and affiliates, as disclosed in these notes.

The Operating Partnership holds substantially all the assets of the Company and holds the ownership interests in the Company’s joint ventures. The Operating Partnership conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from public equity issuances by Digital Realty Trust, Inc., which are generally contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generally generates the capital required by the Company’s business primarily through the Operating Partnership’s operations, by the Operating Partnership’s or its affiliates' direct or indirect incurrence of indebtedness or through the issuance of partnership units.
The presentation of noncontrolling interests in operating partnership, stockholders’ equity and partners’ capital are the main areas of difference between the condensed consolidated financial statements of Digital Realty Trust, Inc. and those of the Operating Partnership. The common limited partnership interests held by the limited partners in the Operating Partnership are presented as limited partners’ capital within partners’ capital in the Operating Partnership’s condensed consolidated financial statements and as noncontrolling interests in operating partnership within equity in Digital Realty Trust, Inc.’s condensed consolidated financial statements. The common and preferred partnership interests held by Digital Realty Trust, Inc. in the Operating Partnership are presented as general partner’s capital within partners’ capital in the Operating Partnership’s condensed consolidated financial statements and as preferred stock, common stock, additional paid-in capital and accumulated dividends in excess of earnings within stockholders’ equity in Digital Realty Trust, Inc.’s condensed consolidated financial statements. The differences in the presentations between stockholders’ equity and partners’ capital result from the differences in the equity issued at the Digital Realty Trust, Inc. and the Operating Partnership levels.

DIGITAL REALTY TRUST, INC. AND SUBSIDIARIES
DIGITAL REALTY TRUST, L.P. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
September 30, 2018 and 2017

To help investors understand the significant differences between the Company and the Operating Partnership, these consolidated financial statements present the following separate sections for each of the Company and the Operating Partnership:
condensed consolidated face financial statements; and
the following notes to the condensed consolidated financial statements:
"Debt of the Company" and "Debt of the Operating Partnership";
"Income per Share" and "Income per Unit"; and
"Equity and Accumulated Other Comprehensive Loss, Net of the Company" and "Capital and Accumulated Other Comprehensive Loss of the Operating Partnership".
In the sections that combine disclosure of Digital Realty Trust, Inc. and the Operating Partnership, these notes refer to actions or holdings as being actions or holdings of the Company. Although the Operating Partnership is generally the entity that enters into contracts and joint ventures and holds assets and debt, reference to the Company is appropriate because the business is one enterprise and the Company generally operates the business through the Operating Partnership.
(b) Cash Equivalents
For the purpose of the condensed consolidated statements of cash flows, we consider short-term investments with original maturities of 90 days or less to be cash equivalents. As of September 30, 2018, cash equivalents consist of investments in money market instruments.
(c) Investments in Unconsolidated Joint Ventures
The Company’s investments in unconsolidated joint ventures are accounted for using the equity method, whereby our investment is increased for capital contributed and our share of the joint venture's net income and decreased by distributions we receive and our share of any losses of the joint ventures. We do not record losses of the joint ventures in excess of our investment balances unless we are liable for the obligations of the joint venture or are otherwise committed to provide financial support to the joint venture. Likewise, and as long as we have no explicit or implicit obligations to the joint venture, we will suspend equity method accounting to the extent that cash distributions exceed our investment balances until those unrecorded earnings exceed the excess distributions previously recognized in income. In this case, we will apply cost accounting concepts which tie income recognition to the receipt of cash.  Cost basis accounting concepts will apply until earnings exceed the excess distributions previously recognized in income.
We amortize the difference between the cost of our investments in the joint ventures and the book value of the underlying equity into income on a straight-line basis consistent with the lives of the underlying assets. The amortization of this difference was immaterial for the three and nine months ended September 30, 2018 and 2017, respectively.

(d) Capitalization of Costs

Direct and indirect project costs that are clearly associated with the development of properties are capitalized as incurred. Project costs include all costs directly associated with the development of a property, including construction costs, interest, property taxes, insurance, legal fees and costs of personnel working on the project. Indirect costs that do not clearly relate to the projects under development are not capitalized and are charged to expense as incurred.

Capitalization of costs begins when the activities necessary to get the development project ready for its intended use begins, which include costs incurred before the beginning of construction. Capitalization of costs ceases when the development project is substantially complete and ready for its intended use. Determining when a development project commences and when it is substantially complete and ready for its intended use involves a degree of judgment. We generally consider a development project to be substantially complete and ready for its intended use upon receipt of a certificate of occupancy. If and when development of a property is suspended pursuant to a formal change in the planned use of the property, we will evaluate whether the accumulated costs exceed the estimated value of the project and write off the amount of any such excess accumulated costs. For a development project that is suspended for reasons other than a formal change in the planned use of such property, the accumulated project costs are evaluated for impairment consistent with our impairment policies for long-lived assets. Capitalized costs are allocated to the specific components of a project that are benefited.

DIGITAL REALTY TRUST, INC. AND SUBSIDIARIES
DIGITAL REALTY TRUST, L.P. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
September 30, 2018 and 2017

During the three months ended September 30, 2018 and 2017, we capitalized interest of approximately $9.7 million and $5.3 million, respectively. We capitalized interest of approximately $25.3 million and $13.7 million during the nine months ended September 30, 2018 and 2017, respectively. We capitalized amounts relating to compensation and other overhead expense of employees direct and incremental to construction and successful leasing activities of approximately $19.5 million and $20.8 million during the three months ended September 30, 2018 and 2017, respectively, and approximately $55.1 million and $58.4 million during the nine months ended September 30, 2018 and 2017, respectively. In addition to capitalized cash compensation, approximately $6.4 million and $11.1 million of capitalized costs primarily related to external leasing commissions are included in improvements to and advances for investments in real estate in cash flows from investing activities in the condensed consolidated statements of cash flows for the nine months ended September 30, 2018 and 2017, respectively.
(e) Goodwill

Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired and tangible and intangible liabilities assumed in a business combination. Goodwill is not amortized.  We perform an annual impairment test for goodwill and between annual tests, we evaluate goodwill for impairment whenever events or changes in circumstances occur that would more likely than not reduce the fair value of a reporting unit below its carrying value.  In our impairment tests of goodwill, we first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If based on this assessment, we determine that the fair value of the reporting unit is not less than its carrying value, then performing the additional two-step impairment test is unnecessary. If our qualitative
assessment indicates that goodwill impairment is more likely than not, we perform a two-step impairment test. We test goodwill for impairment under the two-step impairment test by first comparing the book value of net assets including goodwill to the fair value of the reporting unit. If the fair value is determined to be less than the book value of the net assets, including goodwill, a second step is performed to compute the amount of impairment as the difference between the implied fair value of goodwill and its carrying value. We estimate the fair value of the reporting units using discounted cash flows. If the carrying value of goodwill exceeds its implied fair value, an impairment charge is recognized. We have not recognized any goodwill impairments since our inception. Since some of the goodwill is denominated in foreign currencies, changes to the goodwill balance occur over time due to changes in foreign exchange rates.

(f) Share-Based Compensation
The Company measures all share-based compensation awards at fair value on the date they are granted to employees and directors, and recognizes compensation cost, net of forfeitures, over the requisite service period for awards with only a service condition. The estimated fair value of the long-term incentive units and Class D units (discussed in Note 13) granted by us is being amortized on a straight-line basis over the expected service period.

The fair value of share-based compensation awards that contain a market condition is measured using a Monte Carlo simulation method and not adjusted based on actual achievement of the market condition.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
September 30, 2018 and 2017

(g) Assets and Liabilities Measured at Fair Value

Fair value under U.S. GAAP is a market-based measurement, not an entity-specific measurement. Therefore, our fair value measurements are 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, we use a fair-value hierarchy 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 lowest level input that is significant would be used to determine the fair-value measurement in its entirety. Our assessment of the significance of a particular input to the fair-value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
(h) Derivative Instruments

Derivative financial instruments are employed to manage risks, including foreign currency and interest rate exposures and are not used for trading or speculative purposes. As part of the Company’s risk management program, a variety of financial instruments, such as interest rate swaps and foreign exchange contracts, may be used to mitigate interest rate exposure and foreign currency exposure. The Company recognizes all derivative instruments in the balance sheet at fair value.

Changes in the fair value of derivatives are recognized periodically either in earnings or in stockholders’ equity as a component of accumulated other comprehensive income (loss), depending on whether the derivative financial instrument is undesignated or qualifies for hedge accounting, and if so, whether it represents a fair value, cash flow, or net investment hedge. Gains and losses on derivatives designated as cash flow hedges, to the extent they are included in the assessment of effectiveness, are recorded in other comprehensive income (loss) and subsequently reclassified to earnings to offset the impact of the hedged items when they occur. In the event it becomes probable the forecasted transaction to which a cash flow hedge relates will not occur, the derivative would be terminated and the amount in other comprehensive income (loss) would be recognized in earnings. Changes in the fair value of derivatives that are designated and qualify as a hedge of the net investment in foreign operations, to the extent they are included in the assessment of effectiveness, are reported in other comprehensive income (loss) and are deferred until disposal of the underlying assets. Gains and losses representing components excluded from the assessment of effectiveness for cash flow and fair value hedges are recognized in earnings on a straight-line basis in the same caption as the hedged item over the term of the hedge. Gains and losses representing components excluded from the assessment of effectiveness for net investment hedges are recognized in earnings on a straight-line basis over the term of the hedge.

The net interest paid or received on interest rate swaps is recognized as interest expense. Gains and losses resulting from the early termination of interest rate swap agreements are deferred and amortized as adjustments to interest expense over the remaining period of the debt originally covered by the terminated swap.
See Note 14 for further discussion on derivative instruments.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)
September 30, 2018 and 2017

(i) Income Taxes
Digital Realty Trust, Inc. has elected to be treated as a real estate investment trust (a “REIT”) for federal income tax purposes. As a REIT, Digital Realty Trust, Inc. generally is not required to pay federal corporate income tax to the extent taxable income is currently distributed to its stockholders. If Digital Realty Trust, Inc. fails to qualify as a REIT in any taxable year, it will be subject to federal income tax (including any applicable alternative minimum tax for taxable years prior to 2018) on its taxable income.

The Company is subject to foreign, state and local income taxes in the jurisdictions in which it conducts business. The Company’s taxable REIT subsidiaries are subject to federal, state and foreign income taxes to the extent there is taxable income. Accordingly, the Company recognizes current and deferred income taxes for its taxable REIT subsidiaries, including federal, state and non-U.S. jurisdictions, as appropriate.
We assess our significant tax positions in accordance with U.S. GAAP for all open tax years and determine whether we have any material unrecognized liabilities from uncertain tax benefits. If a tax position is not considered “more-likely-than-not” to be sustained solely on its technical merits, no benefits of the tax position are to be recognized (for financial statement purposes). As of September 30, 2018 and December 31, 2017, we had no assets or liabilities for uncertain tax positions. We classify interest and penalties from significant uncertain tax positions as interest expense and operating expense, respectively, in our condensed consolidated income statements. For the three and nine months ended September 30, 2018 and 2017, we had no such interest or penalties. The tax year 2015 and thereafter remain open to examination by the major taxing jurisdictions with which the Company files tax returns.
See Note 10 for further discussion on income taxes.
 
(j) Presentation of Transactional-based Taxes
We account for transactional-based taxes, such as value added tax, or VAT, for our international properties on a net basis.

(k) Redeemable Noncontrolling Interests

Redeemable noncontrolling interests include amounts related to partnership units issued by consolidated subsidiaries of the Company in which redemption for equity is outside the control of the Company.  Partnership units which are determined to be contingently redeemable for cash under the Financial Accounting Standards Board’s "Distinguishing Liabilities from Equity" guidance are classified as redeemable noncontrolling interests and presented in the mezzanine section between total liabilities and stockholder’s equity on the Company’s condensed consolidated balance sheets. The amounts of consolidated net income attributable to the Company and to the noncontrolling interests are presented on the Company’s condensed consolidated income statements.
(l) Revenue Recognition

The majority of our revenue is derived from lease arrangements, which we account for in accordance with “Leases (Topic 840)”. We account for the non-lease components within our lease arrangements, as well as other sources of revenue, in accordance with “Revenue from Contracts with Customers (Topic 606)”. Revenue recognized as a result of applying Topic 840 was 97% and Topic 606 was 3% of total operating revenue for the three and nine months ended September 30, 2018.

Our leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the terms of the leases, which may span multiple years. The excess of rents recognized over amounts contractually due pursuant to the underlying leases is included in deferred rent in the accompanying condensed consolidated balance sheets and contractually due but unpaid rents are included in accounts and other receivables.
 
Tenant reimbursements for real estate taxes, common area maintenance, and other recoverable costs under our leases are recognized in the period that the expenses are incurred. Lease termination fees are recognized over the remaining term of the lease, effective as of the date the lease modification is finalized, assuming collection is not considered doubtful. As discussed above, we recognize amortization of the value of acquired above or below-market tenant leases as a reduction of rental revenue in the case of above-market leases or an increase to rental revenue in the case of below-market leases.

Interconnection services are included in rental and other services on the condensed consolidated income statements and are generally provided on a month-to-month, one-year or multi-year term. Interconnection services include port and cross-connect services. Port services are typically sold on a one-year or multi-year term and revenue is recognized on a recurring monthly basis (straight-line). The Company bills customers on a monthly basis and recognizes the revenue over the period the service is provided. Revenue for cross-connect installations is generally recognized in the period the cross-connect is installed. Interconnection services that are not specific to a particular space are accounted for under Topic 606 and have terms that are generally one year or less.

Occasionally, customers engage the Company for certain services. The nature of these services historically involves property management and construction management. The proper revenue recognition of these services can be different, depending on whether the arrangements are service revenue or contractor type revenue.

Service revenues are typically recognized on an equal monthly basis based on the minimum fee to be earned. The monthly amounts could be adjusted depending on if certain performance milestones are met.

Fee income arises primarily from contractual management agreements with entities in which we have a noncontrolling interest. The management fees are recognized as earned under the respective agreements. Management and other fee income related to partially owned noncontrolled entities are recognized to the extent attributable to the unaffiliated interest.

We make subjective estimates as to when our revenue is earned and the collectability of our accounts receivable related to minimum rent, deferred rent, expense reimbursements, lease termination fees and other income. We specifically analyze accounts receivable and historical bad debts, customer concentrations, customer creditworthiness and current economic trends when evaluating the adequacy of the allowance for bad debts. These estimates have a direct impact on our net revenue because a higher bad debt allowance would result in lower net revenue, and recognizing rental revenue as earned in one period versus another would result in higher or lower net revenue for a particular period.

(m) Transaction and Integration Expense
Transaction and integration expense includes business combination expenses, other business development expenses and other expenses to integrate newly acquired investments, which are expensed as incurred. Transaction expenses include closing costs, broker commissions and other professional fees, including legal and accounting fees related to business combinations or acquisitions that were not consummated. Integration costs include transition costs associated with organizational restructuring (such as severance and retention payments and recruiting expenses), third-party consulting expenses directly related to the integration of acquired companies (in areas such as cost savings and synergy realization, technology and systems work), and internal costs such as training, travel and labor, reflecting time spent by Company personnel on integration activities and projects. Recurring costs are recorded in general and administrative expense. 

(n) Gains on Sale of Properties

As of January 1, 2018, we began accounting for the sale of real estate properties under Financial Accounting Standards Board, or FASB, Accounting Standards Update, or ASU, No. 2017-05, Other Income—Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20), which provides for revenue recognition based on transfer of ownership. All properties were non-financial real estate assets and thus not businesses which were sold to noncustomers with no performance obligations subsequent to transfer of ownership. During the nine months ended September 30, 2018, the Company sold real estate properties for gross proceeds of $291.7 million, and a recorded net gain of $80.4 million.

(o) Management’s 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 and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates made. On an on-going basis, we evaluate our estimates, including those related to the valuation of our real estate properties, tenant relationship value, goodwill, contingent consideration, accounts receivable and deferred rent receivable, performance-based equity compensation plans and the completeness of accrued liabilities. We base our estimates on historical experience, current market conditions, and various other assumptions that are believed to be reasonable under the circumstances. Actual results may vary from those estimates and those estimates could vary under different assumptions or conditions.
(p) Segment and Geographic Information
All of our properties generate similar revenues and expenses related to tenant rent and services and reimbursements and operating expenses. The sale and delivery of our products is consistent across all properties and although services are provided to a wide range of customers, the types of real estate services provided to them are standardized throughout the portfolio. As such, the properties in our portfolio have similar economic characteristics and the nature of the products and services provided to our customers and the method to distribute such services are consistent throughout the portfolio. In addition, the chief operating decision makers evaluate operating performance and make resource allocation decisions for the portfolio as a whole, rather than by property type or revenue stream. Consequently, our properties qualify for aggregation into one reporting segment.
Operating revenues from properties in the United States were $629.3 million and $478.2 million and outside the United States were $139.7 million and $131.7 million for the three months ended September 30, 2018 and 2017, respectively. Operating revenues from properties in the United States were $1.8 billion and $1.3 billion and outside the United States were $421.3 million and $380.0 million for the nine months ended September 30, 2018 and 2017, respectively. We had investments in real estate located in the United States of $10.8 billion and $10.5 billion, and outside the United States of $3.3 billion and $3.1 billion, as of September 30, 2018 and December 31, 2017, respectively.
Operating revenues from properties located in the United Kingdom were $72.6 million and $70.1 million, or 9.4% and 11.5% of total operating revenues, for the three months ended September 30, 2018 and 2017, respectively. Operating revenues from properties located in the United Kingdom were $221.9 million and $202.8 million, or 9.8% and 11.7% of total operating revenues, for the nine months ended September 30, 2018 and 2017, respectively. No other foreign country comprised more than 10% of total operating revenues for each of these periods. We had investments in real estate located in the United Kingdom of $1.6 billion and $1.7 billion, or 11.6% and 12.1% of total long-lived assets, as of September 30, 2018 and December 31, 2017, respectively. No other foreign country comprised more than 10% of total long-lived assets as of September 30, 2018 and December 31, 2017.

(q) New Accounting Pronouncements
New Accounting Standards Adopted

In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities". The new standard amends the hedge accounting recognition and presentation requirements in Accounting Standards Codification, or ASC, 815. As permitted by ASU No. 2017-12, the Company early adopted this standard in the first quarter of 2018 on a prospective basis. Refer to Note 2(h), Derivative Instruments, for our policy related to the adoption of this standard.

In January 2016, the FASB issued ASU No. 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities". The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and to record changes in instruments specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. The principal effect of ASU No. 2016-01 on our condensed consolidated financial statements is that, prior to adoption of ASU No. 2016-01, changes in the fair values of investments in equity securities with readily determinable fair values or redemption values were recognized in other comprehensive income until realized, while under ASU No. 2016-01 all changes in the fair values of these equity securities are

recognized in current earnings. The update is effective for fiscal years beginning after December 15, 2017, and for interim periods therein. We adopted this standard in the first quarter of 2018 and the adoption did not have a material impact on our condensed consolidated financial statements. 
In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)", and since that date has issued several additional ASUs intended to clarify certain aspects of ASU No. 2014-09 and to provide for certain practical expedients entities may elect upon adoption. Collectively, these ASUs outline a single comprehensive model for entities to use in accounting for revenues arising from contracts with customers. We adopted Topic 606 in the first quarter of 2018 using the modified retrospective transition method and applied Topic 606 to those contracts that were not completed as of January 1, 2018. The results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be presented under Topic 605. Our financial statements did not recognize a material effect from the cumulative impact of adopting Topic 606 as the new accounting standard does not impact lessor accounting. Refer to Note 2(l), Revenue Recognition, for the updated policy related to the adoption of this standard.
New Accounting Standards Issued but not yet Adopted
In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)", which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Accounting for leases with a term of 12 months or less will be similar to existing guidance for operating leases today. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases.
ASU No. 2016-02 is expected to impact the Company’s consolidated financial statements for leases where the Company is a lessee, primarily for the Company’s data center operating leases, ground leases and administrative office leases, and the Company will be required to record a lease liability and a right of use asset on its condensed consolidated balance sheet at fair value upon adoption. ASU No. 2016-02 also limits the capitalization of leasing costs to initial direct costs, which will likely result in a reduction to our capitalized leasing costs and an increase in expenses, though the amount of such change is highly dependent upon the leasing compensation structures in place at the time of adoption.
ASU No. 2016-02 supersedes the previous leases standard, Leases (Topic 840). The standard is effective on January 1, 2019, with early adoption permitted. The new leasing standard requires modified retrospective transition. In March 2018, the FASB affirmed a proposed ASU that would allow entities to elect a simplified transition approach which would require applying the provisions of the new guidance at the effective date as opposed to the earliest period presented under the modified retrospective approach.
A set of practical expedients for implementation, which must be elected as a package and for all leases, may also be elected. These practical expedients include relief from re-assessing lease classification at the adoption date for expired or existing leases, although a right-of-use asset and lease liability would still be recorded for such leases. In March 2018, the FASB affirmed a proposed ASU that would include creating a practical expedient that would provide lessors an option not to separate lease and non-lease components when certain criteria are met and instead account for those components as a single component.
In July 2018, the FASB issued ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements.” This ASU permits an entity to elect an additional transition method to the existing modified retrospective transition requirements. Under the new transition method, an entity could adopt the provisions of ASU No. 2016-02 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption without adjustment to the financial statements for periods prior to adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard will continue to be in accordance with the previous lease guidance in Topic 840.

We are in the process of finalizing our review of our lease agreements in light of Topic 842 guidance, implementing a financial lease accounting system, evaluating internal control changes to support management in the accounting for and disclosure of leasing activities, and assessing available transition practical expedients. While we are still in the process of

completing our implementation evaluation of ASU No. 2016-02, we currently believe the most significant changes to our financial statements relate to the recognition of a lease liability and offsetting right-of-use asset in our consolidated balance sheet for operating leases. ASU No. 2016-02 will be effective for us as of January 1, 2019.

In January 2017, the FASB issued guidance codified in ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". ASU No. 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 ASU No. 2017-04 to have a material impact on our consolidated financial statements.

In June 2018, the FASB issued ASU No. 2018-07, “Improvements to Nonemployee Share-Based Payment Accounting,” which more closely aligns the accounting for employee and nonemployee share-based payments. The standard will be effective for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. We do not expect the provisions of ASU No. 2018-07 to have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU amends existing fair value measurement disclosure requirements by adding, changing, or removing certain disclosures. ASU No. 2018-13 will be effective for us as of January 1, 2020, and earlier adoption is permitted. We are currently reviewing the impact this ASU will have on our financial statements.

The amounts reflected in the tables above, except for our investment in and share of equity in earnings of unconsolidated joint ventures, are based on the historical financial information of the individual joint ventures. The debt of our unconsolidated joint ventures generally are non-recourse to us, except for customary exceptions pertaining to such matters as intentional misuse of funds, environmental conditions, and material misrepresentations.

Differences between the Company’s investment in the joint ventures and the amount of the underlying equity in net assets of the joint ventures are due to basis differences resulting from the Company’s equity investment recorded at its historical basis versus the fair value of the Company’s contributed interest in the joint ventures. Our proportionate share of the earnings or losses related to these unconsolidated joint ventures is reflected as equity in earnings of unconsolidated joint ventures on the accompanying condensed consolidated income statements.

 Global Revolving Credit Facility
On January 15, 2016, we refinanced our global revolving credit facility and entered into a global senior credit agreement for a $2.0 billion senior unsecured revolving credit facility, which we refer to as the global revolving credit facility, that replaced the $2.0 billion revolving credit facility executed on August 15, 2013, as amended. The global revolving credit facility has an accordion feature that enables us to increase the borrowing capacity of the credit facility to up to $2.5 billion, subject to the receipt of lender commitments and other conditions precedent. The refinanced facility matures on January 15, 2020, with two six-month extension options available. The interest rate for borrowings under the global revolving credit facility equals the applicable index plus a margin which is based on the credit ratings of our long-term debt and is currently 100 basis points. An annual facility fee on the total commitment amount of the facility, based on the credit ratings of our long-term debt, currently 20 basis points, is payable quarterly. Funds may be drawn in U.S., Canadian, Singapore, Australian and Hong Kong dollars, as well as Euro, British pound sterling and Japanese yen. As of September 30, 2018, interest rates are based on 1-month LIBOR, 1-month EURIBOR, 1-month BBR, 1-month HIBOR, 1-month JPY LIBOR, 1-month SOR and 1-month CDOR, plus a margin of 1.00%. We have used and intend to use available borrowings under the global revolving credit facility to acquire additional properties, fund development opportunities and for general working capital and other corporate purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or equity securities. As of September 30, 2018, approximately $44.6 million of letters of credit were issued.
The global revolving credit facility contains various restrictive covenants, including limitations on our ability to incur additional indebtedness, make certain investments or merge with another company, and requirements to maintain financial coverage ratios, including with respect to unencumbered assets. In addition, the global revolving credit facility restricts Digital Realty Trust, Inc. from making distributions to its stockholders, or redeeming or otherwise repurchasing shares of its capital

stock, after the occurrence and during the continuance of an event of default, except in limited circumstances including as necessary to enable Digital Realty Trust, Inc. to maintain its qualification as a REIT and to minimize the payment of income or excise tax. As of September 30, 2018, we were in compliance with all of such covenants.
Unsecured Term Loans

On January 15, 2016, we refinanced our senior unsecured multi-currency term loan facility and entered into a term loan agreement, which governs (i) a $1.25 billion 5-year senior unsecured term loan, which we refer to as the 5-Year Term Loan, and (ii) a $300 million 7-year senior unsecured term loan, which we refer to as the 7-Year Term Loan. The 2016 term loan agreement replaced the $1.0 billion term loan agreement executed on April 16, 2012, as amended. The 5-Year Term Loan matures on January 15, 2021 and the 7-Year Term Loan matures on January 15, 2023. In addition, we have the ability from time to time to increase the aggregate size of lending under the 2016 term loan agreement from $1.55 billion to up to $1.8 billion, subject to receipt of lender commitments and other conditions precedent. Interest rates are based on our senior unsecured debt ratings and are currently 110 basis points and 155 basis points over the applicable index for floating rate advances for the 5-Year Term Loan and the 7-Year Term Loan, respectively. Funds may be drawn in U.S., Canadian, Singapore, Australian and Hong Kong dollars, as well as Euro, British pound sterling and Japanese yen. Based on exchange rates in effect at September 30, 2018, the balance outstanding is approximately $1.4 billion, excluding deferred financing costs. We have used borrowings under the term loans for acquisitions, repayment of indebtedness, development, working capital and general corporate purposes. The covenants under the term loans are consistent with our global revolving credit facility and, as of September 30, 2018, we were in compliance with all of such covenants.

3.750% Notes due 2030

On October 17, 2018, Digital Stout Holding, LLC, a wholly owned subsidiary of Digital Realty Trust, L.P., issued and sold £400.0 million (approximately $524.6 million based on the exchange rate on October 17, 2018) aggregate principal amount of 3.750% Guaranteed Notes due 2030, or the 2030 Notes. The 2030 Notes are senior unsecured obligations of Digital Stout Holding, LLC and are fully and unconditionally guaranteed by Digital Realty Trust, Inc. and Digital Realty Trust, L.P. Net proceeds from the offering were approximately £393.5 million (approximately $516.1 million based on the exchange rate on October 17, 2018) after deducting managers’ discounts and estimated offering expenses. We intend to use the net proceeds from the offering of the 2030 Notes to repay borrowings outstanding under the operating partnership’s global credit facilities, acquire additional properties or businesses, fund development opportunities, and to provide for working capital and other general corporate purposes, including potentially for the repayment of other debt or the repurchase, redemption, or retirement of outstanding debt securities, or a combination of the foregoing. The indenture governing the 2030 Notes contains certain covenants, including (1) a leverage ratio not to exceed 60%, (2) a secured debt leverage ratio not to exceed 40% and (3) an interest coverage ratio of greater than 1.50, and also requires us to maintain total unencumbered assets of not less than 150% of the aggregate principal amount of unsecured debt.

10. Income Taxes
Digital Realty Trust, Inc. has elected to be treated and believes that it has been organized and has operated in a manner that has enabled it to qualify as a REIT for federal income tax purposes. As a REIT, Digital Realty Trust, Inc. is generally not subject to corporate level federal income taxes on taxable income distributed currently to its stockholders. Since inception, Digital Realty Trust, Inc. has distributed at least 100% of its taxable income annually and intends to do so for the tax year ending December 31, 2018. As such, no provision for federal income taxes has been included in the Company's accompanying condensed consolidated financial statements for the three and nine months ended September 30, 2018 and 2017.
The Operating Partnership is a partnership and is not required to pay federal income tax. Instead, taxable income is allocated to its partners, who include such amounts on their federal income tax returns. As such, no provision for federal income taxes has been included in the Operating Partnership’s accompanying condensed consolidated financial statements.
We have elected taxable REIT subsidiary (“TRS”) status for some of our consolidated subsidiaries. In general, a TRS may provide services that would otherwise be considered impermissible for REITs to provide and may hold assets that REITs cannot hold directly. Income taxes for TRS entities were accrued, as necessary, for the three and nine months ended September 30, 2018 and 2017.
For our TRS entities and foreign subsidiaries that are subject to U.S. federal, state and foreign income taxes, deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the temporary differences reverse. A valuation allowance for deferred tax assets is provided if we believe it is more likely than not that the deferred tax asset may not be realized, based on available evidence at the time the determination is made. An increase or decrease in the valuation allowance that results from the change in circumstances that causes a change in our judgment about the realizability of the related deferred tax asset is included in the income statement. Deferred tax assets (net of valuation allowance) and liabilities for our TRS entities and foreign subsidiaries were accrued, as necessary, for the three and nine months ended September 30, 2018 and 2017. As of September 30, 2018 and December 31, 2017, we had deferred tax liabilities net of deferred tax assets of approximately $158.3 million and $167.0 million, respectively, primarily related to our foreign properties, classified in accounts payable and other accrued expenses in the condensed consolidated balance sheet. The majority of our net deferred tax liability relates to differences between tax basis and book basis of the assets acquired in the Sentrum portfolio acquisition during 2012 and the European portfolio acquisition in July 2016. The valuation allowance against the deferred tax assets at September 30, 2018 and December 31, 2017 relate primarily to net operating loss carryforwards attributable to certain foreign jurisdictions and from the acquisition of Telx, that we do not expect to utilize, and deferred tax assets resulting from certain foreign real estate acquisition costs, which are not depreciated for tax purposes, but are deductible upon ultimate sale of the property. Given the indefinite holding period associated with these assets, realization of these deferred tax assets is not more-likely-than-not as of September 30, 2018 and December 31, 2017.

The federal tax legislation enacted on December 22, 2017, commonly known as the Tax Cuts and Jobs Act (the “2017 Tax Legislation”), reduced the corporate federal tax rate in the U.S. to 21%, effective upon January 1, 2018. As such, deferred tax assets and liabilities are remeasured using the lower corporate federal tax rate at December 31, 2017. While we do not expect other material impacts, the new tax rules are complex and lack developed administrative guidance. We continue to work with our tax advisors to analyze and determine the full impact that the 2017 Tax Legislation as a whole will have on us.

11. Equity and Accumulated Other Comprehensive Loss, Net

(a) Forward Equity Sale

On September 27, 2018, Digital Realty Trust, Inc. completed an underwritten public offering of 9,775,000 shares of its common stock (including 1,275,000 shares from the exercise in full of the underwriters' option to purchase additional shares), all of which were offered in connection with forward sale agreements it entered into with certain financial institutions acting as forward purchasers. The forward purchasers borrowed and sold an aggregate of 9,775,000 shares of Digital Realty Trust, Inc.’s common stock in the public offering. Digital Realty Trust, Inc. did not receive any proceeds from the sale of our common stock by the forward purchasers in the public offering. The Company expects to receive net proceeds of approximately $1.1 billion (net of fees and estimated expenses) upon full physical settlement of the forward sale agreements, which is anticipated to be no later than September 27, 2019.

(b) Noncontrolling Interests in Operating Partnership
Noncontrolling interests in the Operating Partnership relate to the interests that are not owned by Digital Realty Trust, Inc. The following table shows the ownership interests in the Operating Partnership as of September 30, 2018 and December 31, 2017:

Limited partners have the right to require the Operating Partnership to redeem part or all of their common units for cash based on the fair market value of an equivalent number of shares of Digital Realty Trust, Inc. common stock at the time of redemption. Alternatively, Digital Realty Trust, Inc. may elect to acquire those common units in exchange for shares of Digital Realty Trust, Inc. common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events. Pursuant to authoritative accounting guidance, Digital Realty Trust, Inc. evaluated whether it controls the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the share settlement of the noncontrolling Operating Partnership common and incentive units. Based on the results of this analysis, we concluded that the common units and incentive units of the Operating Partnership met the criteria to be classified within equity, except for certain common units issued to certain former unitholders in DuPont Fabros Technology, L.P. ("DFT Operating Partnership") in the DuPont Fabros Technology merger ("DFT Merger"), which are subject to certain restrictions and, accordingly, are not presented as permanent equity in the condensed consolidated balance sheet.

In connection with the initial public offering of DuPont Fabros Technology, Inc. ("DFT") in 2007, DFT, the DFT Operating Partnership and certain DFT Operating Partnership unitholders entered into a tax protection agreement to assist such unitholders in deferring certain U.S. federal income tax liabilities that may have otherwise resulted from the contribution transactions undertaken in connection with the initial public offering and the ownership of interests in the DFT Operating Partnership and to set forth certain agreements with respect to other tax matters. In connection with the DFT Merger, certain DFT Operating Partnership unitholders entered into a new tax protection agreement with Digital Realty Trust, Inc. and the Operating Partnership that replaced and superseded the DFT tax protection agreement, effective as of the closing

of the DFT Merger. Pursuant to the new tax protection agreement, such DFT Operating Partnership unitholders entered into a guarantee of certain debt of a subsidiary of the Operating Partnership. The Operating Partnership must offer such DFT Operating Partnership unitholders a new guarantee opportunity in the event any guaranteed debt is repaid prior to March 1, 2023. If the Operating Partnership fails to offer the guarantee opportunity or to allocate guaranteed debt to any such DFT Operating Partnership unitholder as required under the new tax protection agreement, the Operating Partnership generally would be required to indemnify each such DFT Operating Partnership unitholder for the tax liability resulting from such failure, as determined under the new tax protection agreement.
The redemption value of the noncontrolling Operating Partnership common units and the vested incentive units was approximately $891.0 million and $887.0 million based on the closing market price of Digital Realty Trust, Inc. common stock on September 30, 2018 and December 31, 2017, respectively.

Distributions out of Digital Realty Trust, Inc.’s current or accumulated earnings and profits are generally classified as dividends whereas distributions in excess of its current and accumulated earnings and profits, to the extent of a stockholder’s U.S. federal income tax basis in Digital Realty Trust, Inc.’s stock, are generally classified as a return of capital. Distributions in excess of a stockholder’s U.S. federal income tax basis in Digital Realty Trust, Inc.’s stock are generally characterized as capital gain. Cash provided by operating activities has generally been sufficient to fund all distributions, however, in the future we may also need to utilize borrowings under the global revolving credit facility to fund all or a portion of distributions.

12. Capital and Accumulated Other Comprehensive Loss
(a) Allocations of Net Income and Net Losses to Partners
Except for special allocations to holders of profits interest units described below in Note 13(a) under the heading “Incentive Plan—Long-Term Incentive Units,” the Operating Partnership’s net income will generally be allocated to Digital Realty Trust, Inc. (the General Partner) to the extent of the accrued preferred return on its preferred units, and then to the General Partner and the Operating Partnership’s limited partners in accordance with the respective percentage interests in the common units issued by the Operating Partnership. Net loss will generally be allocated to the General Partner and the Operating Partnership’s limited partners in accordance with the respective common percentage interests in the Operating Partnership until the limited partner’s capital is reduced to zero and any remaining net loss would be allocated to the General Partner. However, in some cases, losses may be disproportionately allocated to partners who have guaranteed our debt. The allocations described above are subject to special allocations relating to depreciation deductions and to compliance with the provisions of Sections 704(b) and 704(c) of the Code, and the associated Treasury Regulations.

13. Incentive Plan
On April 28, 2014, our stockholders approved the Digital Realty Trust, Inc., Digital Services, Inc., and Digital Realty Trust, L.P. 2014 Incentive Award Plan (as amended, the 2014 Incentive Award Plan). The 2014 Incentive Award Plan became effective and replaced the Amended and Restated 2004 Incentive Award Plan, as amended, as of the date of such stockholder approval. The material features of the 2014 Incentive Award Plan are described in our definitive Proxy Statement filed on March 19, 2014 in connection with the 2014 Annual Meeting, which description is incorporated herein by reference. Effective as of September 14, 2017, the 2014 Incentive Award Plan was amended to provide that shares which remained available for issuance under DFT’s Amended and Restated 2011 Equity Incentive Plan immediately prior to the closing of the DFT Merger (as adjusted and converted into shares of Digital Realty Trust, Inc.’s common stock) may be used for awards under the 2014 Incentive Award Plan and will not reduce the shares authorized for grant under the 2014 Incentive Award Plan, to the extent that using such shares is permitted without stockholder approval under applicable stock exchange rules. In connection with the amendment to the 2014 Incentive Award Plan, on September 22, 2017, Digital Realty Trust, Inc. registered an additional 3.7 million shares that may be issued pursuant to the 2014 Incentive Award Plan.
As of September 30, 2018, approximately 7.1 million shares of common stock, including awards convertible into or exchangeable for shares of common stock, remained available for future issuance under the 2014 Incentive Award Plan. Each long-term incentive unit and each Class D unit issued under the 2014 Incentive Award Plan counts as one share of common stock for purposes of calculating the limit on shares that may be issued under the 2014 Incentive Award Plan and the individual award limits set forth therein.
Below is a summary of our compensation expense for the three and nine months ended September 30, 2018 and 2017 and our unearned compensation as of September 30, 2018 and December 31, 2017 (in millions):

(a) Long-Term Incentive Units

Long-term incentive units, which are also referred to as profits interest units, may be issued to eligible participants for the performance of services to or for the benefit of the Operating Partnership. Long-term incentive units (other than Class D units), whether vested or not, will receive the same quarterly per unit distributions as Operating Partnership common units, which equal the per share distributions on Digital Realty Trust, Inc. common stock. Initially, long-term incentive units do not have full parity with common units with respect to liquidating distributions. If such parity is reached, vested long-term incentive units may be converted into an equal number of common units of the Operating Partnership at any time, and thereafter enjoy all the rights and privileges of common units of the Operating Partnership, including redemption rights. For a discussion of how long-term incentive units achieve parity with common units, see Note 14(a) to our consolidated financial statements for the fiscal year ended December 31, 2017, included in our Annual Report on 10-K for the year ended December 31, 2017.

The grant date fair values, which equal the market price of Digital Realty Trust, Inc. common stock on the applicable grant date(s), are being expensed on a straight-line basis for service awards between two and four years, the current vesting period of the long-term incentive units.

(b) Market Performance-Based Awards
During the nine months ended September 30, 2018 and 2017, the Compensation Committee of the Board of Directors of Digital Realty Trust, Inc. approved the grant of market performance-based Class D units of the Operating Partnership and market performance-based restricted stock units, or RSUs, covering shares of Digital Realty Trust, Inc.’s common stock (collectively, the “awards”), under the 2014 Incentive Award Plan to officers and employees of the Company.
The awards, which were determined to contain a market condition, utilize total shareholder return, or TSR, over a three-year measurement period as the market performance metric. Awards will vest based on Digital Realty Trust, Inc.’s TSR relative to the MSCI US REIT Index, or RMS, over a three-year market performance period, or the Market Performance Period, commencing in January 2018 or January 2017, as applicable (or, if earlier, ending on the date on which a change in control of the Company occurs), subject to continued services. Vesting with respect to the market condition is measured based on the difference between Digital Realty Trust, Inc.’s TSR percentage and the TSR percentage of the RMS, or the RMS Relative Market Performance. In the event that the RMS Relative Market Performance during the Market Performance Period is achieved at the “threshold,” “target” or “high” level as set forth below, the awards will become vested as to the market condition with respect to the percentage of Class D units or RSUs, as applicable, set forth below:

0%
Threshold Level

25%
Target Level

50%
High Level
> 500 basis points
100%
If the RMS Relative Market Performance falls between the levels specified above, the percentage of the award that will vest with respect to the market condition will be determined using straight-line linear interpolation between such levels.

In January 2018, following the completion of the applicable Market Performance Period, the Compensation Committee determined that the high level had been achieved for the 2015 awards and, accordingly, 363,193 class D units (including 36,246 distribution equivalent units that immediately vested on December 31, 2017 upon the high level being achieved) and 49,707 RSUs performance vested, subject to service-based vesting. On February 27, 2018, 50% of the 2015 awards vested and the remaining 50% will vest on February 27, 2019, subject to continued employment through each applicable vesting date.
Following the completion of the applicable Market Performance Period, the 2017 awards that satisfy the market condition, if any, will vest 50% on February 27, 2020 and 50% on February 27, 2021, subject to continued employment through each applicable vesting date. Following the completion of the applicable Market Performance Period, the 2018 awards that satisfy

the market condition, if any, will vest 50% on February 27, 2021 and 50% on February 27, 2022, subject to continued employment through each applicable vesting date.
In the event of a change in control, termination of employment by the Company without cause, or termination of employment by the award recipient for good reason, death, disability or retirement, service-based vesting will be accelerated, in full or on a pro rata basis in any case prior to the completion of the Market Performance Period. However, vesting with respect to the market condition will continue to be measured based on RMS Relative Market Performance during the three-year Market Performance Period (or, in the case of a change in control, shortened Market Performance Period).
The fair values of the 2018 awards and 2017 awards granted were measured using a Monte Carlo simulation to estimate the probability of the market vesting condition being satisfied. Digital Realty Trust, Inc.’s achievement of the market vesting condition is contingent on its TSR over a three-year market performance period, relative to the total shareholder return of the RMS. The Monte Carlo simulation is a probabilistic technique based on the underlying theory of the Black-Scholes formula, which was run for 100,000 trials to determine the fair value of the awards. For each trial, the payoff to an award is calculated at the settlement date and is then discounted to the grant date at a risk-free interest rate. The total expected value of the awards on the grant date was determined by multiplying the average value per award over all trials by the number of awards granted. Assumptions used in the valuations are summarized as follows:
Award Date
 
Expected Stock Price Volatility
 
Risk-Free Interest rate
January 1, 2017
 
25%
 
1.49%
February 28, 2017

March 1, 2018
 
22%
 
2.34%
March 9, 2018
 
22%
 
2.42%
These valuations were performed in a risk-neutral framework, so no assumption was made with respect to an equity risk premium.
As of September 30, 2018, 2,165,692 Class D units and 590,569 market performance-based RSUs had been awarded to our executive officers and other employees. The number of units granted reflects the maximum number of Class D units or market performance-based RSUs, as applicable, which will become vested assuming the achievement of the highest level of RMS Relative Market Performance under the awards and, in the case of the Class D units, also includes distribution equivalent units. The fair value of these awards of approximately $96.7 million will be recognized as compensation expense on a straight-line basis over the expected service period of approximately four years. If the market conditions are not met, at the end of the applicable performance periods, the unamortized amount will be recognized as an expense at that time.

14. Derivative Instruments

Currently, we use interest rate swaps to manage our interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

To comply with the provisions of fair value accounting guidance, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, 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 us and our counterparties. However, as of September 30, 2018, 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 adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. We do not have any fair value measurements on a recurring basis using significant unobservable inputs (Level 3) as of September 30, 2018 or December 31, 2017.

The Company presents its interest rate derivatives in its condensed consolidated balance sheets on a gross basis as interest rate swap assets (recorded in other assets) and interest rate swap liabilities (recorded in accounts payable and other accrued liabilities). As of September 30, 2018, there was no impact from netting arrangements as the Company did not have any derivatives in liability positions.

Cash Flow Hedges of Interest Rate Risk

Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements related to certain floating rate debt obligations. 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-rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

We record all our interest rate swaps on the condensed consolidated balance sheet at fair value. In determining the fair value of our interest rate swaps, we consider the credit risk of our counterparties. These counterparties are generally larger financial institutions engaged in providing a variety of financial services. These institutions generally face similar risks regarding adverse changes in market and economic conditions, including, but not limited to, fluctuations in interest rates, exchange rates, equity and commodity prices and credit spreads. The recent and pervasive disruptions in the financial markets have heightened the risks to these institutions.

Foreign Currency Net Investment Hedges

During the three months ended June 30, 2016, we entered into a series of forward contracts pursuant to which we agreed to sell an amount of foreign currency for an agreed upon amount of U.S. dollars. These forward contracts were executed to manage foreign currency exposures associated with certain transactions. As of June 30, 2016, the forward contracts did not meet the criteria for hedge accounting under GAAP and had a fair value of approximately $37.8 million. On July 1, 2016, the four forward contracts still in place met the criteria for net investment hedge accounting. During the year ended December 31, 2017, we terminated the four forward contracts with a notional amount of GBP 357.3 million. In connection with the settlement, we received approximately $64.0 million in proceeds and the related amount of approximately $26.2 million of accumulated other comprehensive income (AOCI) will remain in AOCI until the Company sells or liquidates its GBP-denominated investments, which has not occurred as of September 30, 2018.

Credit-risk-related Contingent Features

We have agreements with each of our derivative counterparties that contain a provision where we could be declared in default on our derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness. As of September 30, 2018, we did not have any derivatives in a net liability position, and have not posted any collateral related to these agreements.

Company to disclose fair value information about all financial instruments, whether or not recognized in the balance sheets, for which it is practicable to estimate fair value.
The Company’s disclosures of estimated fair value of financial instruments at September 30, 2018 and December 31, 2017 were determined using available market information and appropriate valuation methods. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts.
The carrying amounts for cash and cash equivalents, restricted cash, accounts and other receivables, accounts payable and other accrued liabilities, accrued dividends and distributions, security deposits and prepaid rents approximate fair value because of the short-term nature of these instruments. As described in Note 14 "Derivative Instruments", the interest rate swaps are recorded at fair value.
We calculate the fair value of our mortgage loans, unsecured term loan and unsecured senior notes based on currently available market rates assuming the loans are outstanding through maturity and considering the collateral and other loan terms. In determining the current market rate for fixed rate debt, a market spread is added to the quoted yields on federal government treasury securities with similar maturity dates to our debt. The carrying value of our global revolving credit facility approximates fair value, due to the variability of interest rates.
As of September 30, 2018 and December 31, 2017, the aggregate estimated fair value and carrying value of our global revolving credit facility, unsecured term loans, unsecured senior notes and mortgage loans were as follows (in thousands):

17. Subsequent Events

On October 24, 2018, we refinanced our global revolving credit facility and entered into a global senior credit agreement for a $2.35 billion senior unsecured revolving credit facility, which we refer to as the 2018 global revolving credit facility, that replaced the $2.0 billion revolving credit facility executed on January 15, 2016. The 2018 global revolving credit facility provides for borrowings in Australian dollars, British pounds sterling, Canadian dollars, Euros, Hong Kong dollars, Japanese yen, Singapore dollars, and U.S. dollars, and includes the ability to add additional currencies in the future. The 2018 global revolving credit facility matures on January 24, 2023 with two six-month extension options. In addition, we have the ability from time to time to increase the size of the global revolving credit facility and the unsecured term loans (discussed below), in any combination, by up to $1.25 billion, subject to receipt of lender commitments and other conditions precedent.

On October 24, 2018, we refinanced our senior unsecured multi-currency term loan facility and entered into an amended and restated term loan agreement, which we refer to as the 2018 term loan agreement, which governs (i) a $300.0 million 5-year senior unsecured term loan, which we refer to as the 2023 Term Loan and (ii) an approximately $512.0 million 5-year senior unsecured term loan, which we refer to as the 2024 Term Loan. The 2018 term loan agreement replaced the $1.55 billion term loan agreement executed on January 15, 2016. The 2018 term loan agreement provides for borrowings in Australian dollars, Canadian dollars, Hong Kong dollars, Singapore dollars and U.S. dollars. In addition, we have the ability from time to time to increase the aggregate size of lending under the 2018 term loan agreement and the global revolving credit facility (discussed above), in any combination, by up to $1.25 billion, subject to receipt of lender commitments and other conditions precedent. The maturity date of the 2023 Term Loan is January 15, 2023. The maturity date of the 2024 Term Loan is January 24, 2023 with two six-month extension options.

On October 24, 2018, we entered into a credit agreement for a ¥33.3 billion (approximately $296.5 million based on the exchange rate on October 24, 2018) senior unsecured revolving credit facility, which we refer to as the Yen revolving credit facility. The Yen revolving credit facility provides for borrowings in Japanese yen. In addition, we have the ability from time to time to increase the size of the Yen revolving credit facility to up to ¥93.3 billion (approximately $831.1 million based on the exchange rate on October 24, 2018), subject to receipt of lender commitments and other conditions precedent. The Yen revolving credit facility matures on January 24, 2024.

On October 24, 2018, the Operating Partnership, together with its subsidiary Quill Equity LLC as borrowers, entered into Amendment No. 1 to the Senior Secured Term Loan, which we refer to (as so amended) as the secured term loan agreement, which among other things amended the financial covenants therein to correspond with the financial covenants in the 2018 global senior credit agreement and the 2018 term loan agreement, decreased the applicable rate for eurodollar rate advances, and decreased the applicable rate for base rate advances. As of October 24, 2018, the applicable rate for eurodollar rate advances is the applicable index plus 100 basis points and the applicable rate for base rate advances is the applicable index plus 0 basis points. An annual agency fee is payable quarterly in respect of the commitments under the secured term loan agreement. We are also required to pay certain fees to the administrative agent under the secured term loan agreement.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion should be read in conjunction with the condensed consolidated financial statements and notes thereto appearing elsewhere in this report. This report contains forward-looking statements within the meaning of the federal securities laws. In particular, statements pertaining to the Ascenty acquisition and related financings, the proposed joint venture with Brookfield, expected physical settlement of the forward sale agreements and use of proceeds from any such settlement, our capital resources, expected use of borrowings under our credit facility, litigation matters, portfolio performance, leverage policy, acquisition and capital expenditure plans, capital recycling program, returns on invested capital, supply and demand for data center space, capitalization rates, rents to be received in future periods and expected rental rates on new or renewed data center space, as well as our discussion of “Factors Which May Influence Future Results of Operations,” contain forward-looking statements. Likewise, all of our statements regarding anticipated market conditions, demographics and results of operations are forward-looking statements. You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “pro forma,” “estimates” or “anticipates” or the negative of these words and phrases or similar words or phrases which are predictions of or indicate future events or trends and discussions which do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or intentions. Forward-looking statements involve numerous risks and

54


uncertainties and you should not rely on them as predictions of future events. Forward-looking statements depend on assumptions, data or methods that may be incorrect or imprecise and that we may not be able to realize. 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: reduced demand for data centers or decreases in information technology spending; decreased rental rates, increased operating costs or increased vacancy rates; increased competition or available supply of data center space; the suitability of our data centers and data center infrastructure, delays or disruptions in connectivity or availability of power, or failures or breaches of our physical and information security infrastructure or services; our dependence upon significant customers, bankruptcy or insolvency of a major customer or a significant number of smaller customers, or defaults on or non-renewal of leases by customers; breaches of our obligations or restrictions under our contracts with our customers; our inability to successfully develop and lease new properties and development space, and delays or unexpected costs in development of properties; the impact of current global and local economic, credit and market conditions; our inability to retain data center space that we lease or sublease from third parties; difficulty acquiring or operating properties in foreign jurisdictions; our failure to realize the intended benefits from, or disruptions to our plans and operations or unknown or contingent liabilities related to, our recent acquisitions; our failure to successfully integrate and operate acquired or developed properties or businesses, including Ascenty; difficulties in identifying properties to acquire and completing acquisitions; risks related to joint venture investments (including the proposed joint venture with Brookfield), including as a result of our lack of control of such investments; risks associated with using debt to fund our business activities, including re-financing and interest rate risks, our failure to repay debt when due, adverse changes in our credit ratings or our breach of covenants or other terms contained in our loan facilities and agreements; our failure to obtain necessary debt and equity financing, and our dependence on external sources of capital; financial market fluctuations and changes in foreign currency exchange rates; adverse economic or real estate developments in our industry or the industry sectors that we sell to, including risks relating to decreasing real estate valuations and impairment charges and goodwill and other intangible asset impairment charges; our inability to manage our growth effectively; losses in excess of our insurance coverage; environmental liabilities and risks related to natural disasters; our inability to comply with rules and regulations applicable to our company; Digital Realty Trust, Inc.'s failure to maintain its status as a REIT for federal income tax purposes; Digital Realty Trust, L.P.'s failure to qualify as a partnership for federal income tax purposes; restrictions on our ability to engage in certain business activities; and changes in local, state, federal and international laws and regulations, including related to taxation, 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, new information, data or methods, future events or other changes.

The risks included here are not exhaustive, and additional factors could adversely affect our business and financial performance, including factors and risks included in our annual report on Form 10-K for the year ended December 31, 2017, our current report on Form 8-K filed on September 24, 2018 and in other sections of this report, including under Part II, Item 1A, Risk Factors. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can we assess the impact of all such risk factors on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, you should not place undue reliance on forward-looking statements as a prediction of actual results.
Occupancy percentages included in the following discussion, for some of our properties, are calculated based on factors in addition to contractually leased square feet, including available power, required support space and common area.

Overview
Our company. Digital Realty Trust, Inc. completed its initial public offering of common stock, or our IPO, on November 3, 2004. We believe that we have operated in a manner that has enabled us to qualify, and have elected to be treated, as a REIT under Sections 856 through 860 of the Code. Our Company was formed on March 9, 2004. During the period from our formation until we commenced operations in connection with the completion of our IPO, we did not have any corporate activity other than the issuance of shares of Digital Realty Trust, Inc. common stock in connection with the initial capitalization of the Company. Our Operating Partnership was formed on July 21, 2004.

On September 14, 2017, we completed the acquisition of DuPont Fabros Technology, Inc., in an all-stock merger, which we refer to as the DFT Merger, for equity consideration of approximately $6.2 billion. We believe this transaction expanded our reach with a complementary footprint in top U.S. metropolitan areas while enhancing our ability to meet the growing demand for hyper-scale and public cloud solutions and solidifying our blue-chip customer base. As part of the DFT Merger, we acquired 15 data centers, 14 of which are located in the United States and one is located in Canada.
Business and strategy. Our primary business objectives are to maximize: (i) sustainable long-term growth in earnings and funds from operations per share and unit, (ii) cash flow and returns to our stockholders and our operating partnership’s unitholders through the payment of distributions and (iii) return on invested capital. We expect to accomplish our objectives by achieving superior risk-adjusted returns, prudently allocating capital, diversifying our product offerings and driving revenue growth and operating efficiencies. We plan to focus on our core business of investing in and developing and operating data centers. A significant component of our current and future internal growth is anticipated through the development of our existing space held for development, acquisition of land for future development and acquisition of new properties. We target high quality, strategically located properties containing the physical and connectivity infrastructure that supports the applications and operations of data center and technology industry customers and properties that may be developed for such use. Most of our data center properties contain fully redundant electrical supply systems, multiple power feeds, above-standard cooling systems, raised floor areas, extensive in-building communications cabling and high-level security systems. We focus exclusively on owning, acquiring, developing and operating data centers because we believe that the growth in data center demand and the technology-related real estate industry generally will continue to outpace the overall economy.
As of September 30, 2018, our portfolio included 198 data centers, including 18 data centers held as investments in unconsolidated joint ventures, with approximately 33.4 million rentable square feet including approximately 3.6 million square feet of space under active development and approximately 1.8 million square feet of space held for development. The 18 data centers held as investments in unconsolidated joint ventures have an aggregate of approximately 2.5 million rentable square feet. The 24 parcels of developable land we own as of September 30, 2018 comprised approximately 527 acres. At September 30, 2018, approximately 3.6 million square feet was under construction for Turn-Key Flex® and Powered Base Building® products, all of which are expected to be income producing on or after completion, in seven U.S. metropolitan areas, four European metropolitan areas, three Asian metropolitan areas, two Australian metropolitan areas and one Canadian metropolitan area, consisting of approximately 2.0 million square feet of base building construction and 1.6 million square feet of data center construction.
We have developed detailed, standardized procedures for evaluating new real estate investments to ensure that they meet our financial, technical and other criteria. We expect to continue to acquire additional assets as part of our growth strategy. We intend to aggressively manage and lease our assets to increase their cash flow. We may continue to build out our development portfolio when justified by anticipated demand and returns.
We may acquire properties subject to existing mortgage financing and other indebtedness or we may incur new indebtedness in connection with acquiring or refinancing these properties. Debt service on such indebtedness will have a priority over any cash dividends with respect to Digital Realty Trust, Inc.’s common stock and preferred stock. We are committed to maintaining a conservative capital structure. We target a debt-to-Adjusted EBITDA ratio at or less than 5.5x, fixed charge coverage of greater than three times, and floating rate debt at less than 20% of total outstanding debt. In addition, we strive to maintain a well-laddered debt maturity schedule, and we seek to maximize the menu of our available sources of capital, while minimizing the cost.

Revenue base. As of September 30, 2018, we operated 198 data centers through our Operating Partnership, including 18 data centers held as investments in unconsolidated joint ventures. These data centers are mainly located throughout North America, with 38 located in Europe, seven in Asia and five in Australia.

The following table presents an overview of our portfolio of data centers, including the 18 data centers held as investments in unconsolidated joint ventures, and developable land, based on information as of September 30, 2018.

Current net rentable square feet as of September 30, 2018, which represents the current square feet under lease as specified in the applicable lease agreements plus management’s estimate of space available for lease based on engineering drawings. Includes customers’ proportional share of common areas but excludes space under active development and space held for development.
(2)
Space under active development includes current base building and data center projects in progress, and excludes space held for development. For additional information on the current and future investment for space under active development, see “—Liquidity and Capital Resources of the Operating Partnership—Construction”.
(3)
Space held for development includes space held for future data center development, and excludes space under active development. For additional information on the current investment for space held for development, see “—Liquidity and Capital Resources of the Operating Partnership—Construction”.

As of September 30, 2018, our portfolio, including the 18 data centers held as investments in unconsolidated joint ventures, were approximately 89.5% leased excluding approximately 3.6 million square feet of space under active development and approximately 1.8 million square feet of space held for development. Due to the capital-intensive and long-term nature of the operations being supported, our lease terms are generally longer than standard commercial leases. As of September 30, 2018, our average remaining lease term is approximately five years. Our scheduled lease expirations through December 31, 2019 are 17.7% of rentable square feet excluding month-to-month leases, space under active development and space held for development as of September 30, 2018.
Factors Which May Influence Future Results of Operations

Global market and economic conditions. General economic conditions and the cost and availability of capital may be adversely affected in some or all of the metropolitan areas in which we own properties and conduct our operations. In June 2016, a majority of voters in the United Kingdom elected to withdraw from the European Union in a national referendum. The terms of any withdrawal are subject to ongoing negotiations. Nevertheless, the referendum has created significant uncertainty about the future relationship between the United Kingdom and the European Union, and has given rise to calls for the governments of other European Union member states to consider withdrawal. Instability in the U.S., European, Asia Pacific and other international financial markets and economies may adversely affect our ability, and the ability of our customers, to replace or renew maturing liabilities on a timely basis, access the capital markets to meet liquidity and capital expenditure requirements and may result in adverse effects on our, and our customers’, financial condition and results of operations.

In addition, our access to funds under our global revolving credit facility depends on the ability of the lenders that are parties to such facilities to meet their funding commitments to us. We cannot assure you that long-term disruptions in the global economy and the return of tighter credit conditions among, and potential failures or nationalizations of, third party financial institutions as a result of such disruptions will not have an adverse effect on our lenders. If our lenders are not able to meet their funding commitments to us, our business, results of operations, cash flows and financial condition could be adversely affected.

If we do not have sufficient cash flow to continue operating our business and are unable to borrow additional funds, access our existing lines of credit or raise equity or debt capital, we may need to source alternative ways to increase our liquidity. Such alternatives may include, without limitation, curtailing development activity, disposing of one or more of our

58


properties possibly on disadvantageous terms or entering into or renewing leases on less favorable terms than we otherwise would.
Foreign currency exchange risk. For the nine months ended September 30, 2018 and 2017, we had foreign operations in the United Kingdom, Ireland, France, the Netherlands, Germany, Switzerland, Canada, Singapore, Australia, Japan and Hong Kong, and, as such, are subject to risk from the effects of exchange rate movements of foreign currencies, which may affect future costs and cash flows. Our foreign operations are conducted in the British pound sterling, Euro, Canadian dollar, Singapore dollar, Australian dollar, Japanese Yen and the Hong Kong dollar. Our primary currency exposures are to the British pound sterling, the Euro and the Singapore dollar. The possible exit of the United Kingdom (or any other country) from the European Union, or prolonged periods of uncertainty relating to any of these possibilities, could result in increased foreign currency exchange volatility. We attempt to mitigate a portion of the risk of currency fluctuation by financing our investments in the local currency denominations, although there can be no assurance that this will be effective. As a result, changes in the relation of any such foreign currency to U.S. dollars may affect our revenues, operating margins and distributions and may also affect the book value of our assets, the book value of our debt and the amount of stockholders’ equity.
Rental income. The amount of rental income generated by the data centers 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 and space available from lease terminations. Excluding approximately 3.6 million square feet of space under active development and approximately 1.8 million square feet of space held for development as of September 30, 2018, the occupancy rate of our portfolio, including the 18 data centers held as investments in unconsolidated joint ventures, was approximately 89.5% of our net rentable square feet.
As of September 30, 2018, we had over 2,300 customers in our data center portfolio, including the 13 data centers held in our managed portfolio of unconsolidated joint ventures. As of September 30, 2018, approximately 89% of our leases (on a rentable square footage basis) contained base rent escalations that were either fixed (generally ranging from 2% to 4%) or indexed based on a consumer price index or other similar inflation-related index. We cannot assure you that these escalations will cover any increases in our costs or will otherwise keep rental rates at or above market rates.
The amount of rental income generated by us also depends on maintaining or increasing rental rates at our properties, which in turn depends on several factors, including supply and demand and market rates for data center space. Included in our approximately 25.5 million net rentable square feet, excluding space under active development and space held for development and 18 data centers held as investments in unconsolidated joint ventures, at September 30, 2018 is approximately 1.6 million square feet of data center space with extensive installed tenant improvements available for lease. Our Turn-Key Flex® product is an effective solution for customers who prefer to utilize a partner with the expertise or capital budget to provide extensive data center infrastructure and security. Our expertise in data center construction and operations enables us to lease space to these customers at a premium over other uses. In addition, as of September 30, 2018, we had approximately 3.6 million square feet of space under active development and approximately 1.8 million square feet of space held for development, or approximately 16% of the total rentable space in our portfolio, including the 18 data centers held as investments in unconsolidated joint ventures. Our ability to grow earnings depends in part on our ability to develop space and lease development space at favorable rates, which we may not be able to obtain. Development space requires significant capital investment in order to develop data center facilities that are ready for use and, in addition, we may require additional time or encounter delays in securing tenants for development space. We may purchase additional vacant properties and properties with vacant development space in the future. We will require additional capital to finance our development activities, which may not be available or may not be available on terms acceptable to us, including as a result of the conditions described above under “Global market and economic conditions.”

In addition, the timing between when we sign a new lease with a customer and when that lease commences and we begin to generate rental income may be significant and may not be easily predictable. Certain leases may provide for staggered commencement dates for additional space, the timing of which may be delayed significantly.

Economic downturns, including as a result of the conditions described above under “Global market and economic conditions,” or regional downturns affecting our metropolitan areas or downturns in the data center industry that impair our ability to lease or renew or re-lease space, or otherwise reduce returns on our investments or the ability of our customers to fulfill their lease commitments, as in the case of tenant bankruptcies, could adversely affect our ability to maintain or increase rental rates at our properties.
Scheduled lease expirations. 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 2.8 million square feet of available space in our portfolio, which excludes approximately 3.6 million square feet of space under active development and approximately 1.8 million square feet of space held for development as of September 30, 2018 and the five data centers held as investments in our

59


non-managed unconsolidated joint ventures, leases representing approximately 2.6% and 15.1% of the net rentable square footage of our portfolio are scheduled to expire during the three months ending December 31, 2018 and the year ending December 31, 2019, respectively.

During the nine months ended September 30, 2018, we signed renewal leases totaling approximately 1.1 million square feet of space and new leases totaling approximately 1.7 million square feet of space.

For some of our properties, we calculate square footage based on factors in addition to contractually leased square feet, including power, required support space and common area.
(2)
Rental rates represent annual estimated cash rent per rentable square foot adjusted for straight-line rents in accordance with GAAP. GAAP rental rates are inclusive of tenant concessions, if any.
(3)
Excludes short-term leases.
(4)
Commencement dates for the leases signed range from 2018 to 2021.
(5)
Includes leases signed for new and re-leased space.
Our ability to re-lease or renew expiring space at rental rates equal to or in excess of current rental rates will impact our results of operations. We continue to see strong demand in most of our key metropolitan areas for data center space and, subject to the supply of available data center space in these metropolitan areas, expect the rental rates we are likely to achieve on re-leased or renewed data center space leases for 2018 expirations on an average aggregate basis will generally be higher than the rates currently being paid for the same space on a GAAP basis and slightly down on a cash basis. For the nine months ended September 30, 2018, rents on renewed space increased by an average of 8.6% on a GAAP basis on our Turn-Key Flex® space compared to the expiring rents and increased by an average of 16.1% on a GAAP basis on our Powered Base Building® space compared to the expiring rents. Our past performance may not be indicative of future results, and we cannot assure you that leases will be renewed or that our data centers will be re-leased at all or at rental rates equal to or above the current average rental rates. Further, re-leased/renewed rental rates in a particular metropolitan area may not be consistent with rental rates across our portfolio as a whole and may fluctuate from one period to another due to a number of factors, including local real estate conditions, local supply and demand for data center space, competition from other data center developers or operators, the condition of the property and whether the property, or space within the property, has been developed.

Geographic concentration. We depend on the market for data centers in specific geographic regions and significant changes in these regional metropolitan areas can impact our future results. As of September 30, 2018, our portfolio, including the 18 data centers held as investments in unconsolidated joint ventures, was geographically concentrated in the following metropolitan areas.

Annualized rent is monthly contractual rent (defined as cash base rent before abatements) under existing leases as of September 30, 2018 multiplied by 12. The aggregate amount of abatements for the nine months ended September 30, 2018 was approximately $32.8 million.
Operating expenses. Our operating expenses generally consist of utilities, property and ad valorem taxes, property management fees, insurance and site maintenance costs, as well as rental expenses on our ground and building leases. In particular, our buildings require significant power to support the data center operations contained in them. Many of our leases contain provisions under which the tenants reimburse us for all or a portion of property operating expenses and real estate taxes incurred by us. However, in some cases we are not entitled to reimbursement of property operating expenses, other than utility expense, and real estate taxes under our leases for Turn-Key Flex® facilities. We also incur general and administrative expenses, including expenses relating to our asset management function, as well as significant legal, accounting and other expenses related to corporate governance, Securities Exchange Commission, or the SEC, reporting and compliance with the various provisions of the Sarbanes-Oxley Act. Increases or decreases in such operating expenses will impact our overall performance. We expect to incur additional operating expenses as we continue to expand.
Climate change legislation. In June 2009, the U.S. House of Representatives approved comprehensive clean energy and climate change legislation intended to cut greenhouse gas, or GHG, emissions, via a cap-and-trade program. The U.S. Senate did not subsequently pass similar legislation. New climate change legislation was introduced in the U.S. Senate in 2013, but significant opposition to federal climate change legislation exists.
In the absence of comprehensive federal climate change legislation, over the past several years, regulatory agencies, primarily the U.S. Environmental Protection Agency, or EPA, and states took the lead in regulating GHG emissions in the U.S. Under the Obama administration, the EPA moved aggressively to regulate GHG emissions from automobiles and large stationary sources, including electricity producers, using its own authority under the Clean Air Act. The Trump administration has moved to eliminate or modify certain of the EPA’s GHG emissions regulations and refocus the EPA’s mission away from such regulation.

The EPA made an endangerment finding in 2009 that allows it to create regulations imposing emissions reporting, permitting, control technology installation, and monitoring requirements applicable to certain emitters of GHGs, including facilities that provide electricity to our data centers, although the materiality of the impacts will not be fully known until all regulations are finalized and legal challenges are resolved. Under the Obama administration, the EPA finalized rules imposing

61


permitting and control technology requirements upon certain newly-constructed or modified facilities which emit GHGs under the Clean Air Act New Source Review Prevention of Significant Deterioration, or NSR PSD, and Title V permitting programs. As a result, newly-issued NSR PSD and Title V permits for new or modified electricity generating units (EGUs) and other facilities may need to address GHG emissions, including by requiring the installation of “Best Available Control Technology.” The EPA implemented in December 2015 the “Clean Power Plan” regulating carbon dioxide (CO2) emissions from new and existing coal-fired and natural gas EGUs. Existing EGUs are subject to statewide CO2 emissions reduction targets, an effort designed to achieve a thirty-two percent reduction in nationwide existing EGU CO2 emissions by 2030 (in comparison to 2005 levels). New, modified, and reconstructed EGUs are subject to “New Source Performance Standards” that include both technological requirements and numeric emission limits. However, twenty-four states and a number of industry groups challenged the Clean Power Plan in federal court, and in February 2016 the U.S. Supreme Court issued a stay of the Clean Power Plan until the legal challenges have been decided. In March 2017, President Trump ordered the EPA to review and if appropriate revise or rescind the Clean Power Plan, and the EPA proposed to repeal the Clean Power Plan in October 2017. In August 2018, the EPA proposed the “Affordable Clean Energy Rule” to replace the Clean Power Plan. In August 2018, EPA also proposed weakening Obama-era limitations on GHG emissions from automobiles. Separately, the EPA’s GHG “reporting rule” requires that certain emitters, including electricity generators, monitor and report GHG emissions. The Trump administration may seek to revise or reverse these regulations.

As a result, states may drive near-term regulation to reduce GHG emissions in the United States. At the state level, California implemented a GHG cap-and-trade program that began imposing compliance obligations on industrial sectors, including electricity generators and importers, in January 2013. In September 2016, California adopted legislation calling for a further reduction in GHG emissions to 40% below 1990 levels by 2030, and in July 2017, California extended its cap-and-trade program through 2030. In September 2018, California adopted legislation that will require all of the state’s electricity to come from carbon-free sources by 2045. As another example of state action, in January 2018, New Jersey announced that it would re-join nine other eastern states in the Regional Greenhouse Gas Initiative (RGGI), a market-based program aimed at reducing GHG emissions from power plants. Several other states have announced that they are actively pursuing new GHG reduction programs.

Outside the United States, the European Union, or EU (including the United Kingdom), has been operating since 2005 under a cap-and-trade program, which directly affects the largest emitters of GHGs, including electricity producers from whom we purchase power, and the EU has taken a number of other climate change-related initiatives, including a directive targeted at improving energy efficiency (which introduces energy efficiency auditing requirements).  The Paris Agreement, which was adopted by the United States and 194 other countries and looks to prevent global average temperatures from increasing by more than 2 degrees Celsius above preindustrial levels officially went into force on November 4, 2016. President Trump announced in June 2017 that he will initiate the process to withdraw the United States from the Paris Agreement; however, a number of states have formed groups supporting the Paris Agreement and pledging to fulfill its goals at the state level. National legislation may also be implemented independently by members of the EU.  For example, in the United Kingdom, the implementation of the CRC Energy Efficiency Scheme introduced a mandatory reporting and pricing scheme that is designed to incentivize energy efficiency and cut emissions by large energy users. It is not yet clear how Brexit will impact the United Kingdom’s (or the EU’s) approach to climate change regulation. In Canada, GHG cap and trade programs are in operation or have been announced in Quebec and Nova Scotia. Climate change regulations are in various stages of implementation in other nations as well, including nations where we operate, such as Japan, Singapore, and Australia.

The cost of electric power comprises a significant component of our operating expenses. Any additional taxation or regulation of energy use, including as a result of (i) new legislation that Congress may pass, (ii) the regulations that the EPA has proposed or finalized, (iii) regulations under legislation that states have passed or may pass, or (iv) any further legislation or regulations in the EU or other regions where we operate could significantly increase our costs, and we may not be able to effectively pass all of these costs on to our customers. These matters could adversely impact our business, results of operations, or financial condition.
Interest rates. As of September 30, 2018, we had approximately $1.0 billion of variable rate debt subject to interest rate swap agreements on certain tranches of our unsecured term loans, along with $595.0 million, $452.7 million and $145.1 million of variable rate debt that was outstanding on the global revolving credit facility, the unswapped portion of the unsecured term loans and the floating rate notes due 2019, or the 2019 Notes, respectively. The availability of debt and equity capital may decrease or be on unfavorable terms as a result of the circumstances described above under “Global market and economic conditions” or other factors. The effects on commercial real estate mortgages, if available, include, but may not be limited to: higher loan spreads, tightened loan covenants, reduced loan-to-value ratios resulting in lower borrower proceeds and higher principal payments. Potential future increases in interest rates and credit spreads may increase our interest expense and fixed charges and negatively affect our financial condition and results of operations, potentially impacting our future access to the debt and equity capital markets. Increased interest rates may also increase the risk that the counterparties to our swap

62


agreements will default on their obligations, which could further increase our interest expense. If we cannot obtain capital from third party sources, we may not be able to acquire or develop properties when strategic opportunities exist, satisfy our debt service obligations or pay the cash dividends to Digital Realty Trust, Inc.’s stockholders necessary to maintain its qualification as a REIT.
Demand for data center space. Our portfolio consists primarily of data centers. A decrease in the demand for, or increase in supply of, data center space, Internet gateway facilities or other technology-related real estate would have a greater adverse effect on our business and financial condition than if we owned a portfolio with a more diversified customer base or less specialized use. We have invested in building out additional inventory primarily in what we anticipate will be our active major metropolitan areas prior to having executed leases with respect to this space. We believe that demand in key metropolitan areas such as Northern Virginia, Dallas, Singapore and London is largely in line with supply. We also continue to see strong demand in other key metropolitan areas across our portfolio. However, until this inventory is leased up, which will depend on a number of factors, including available data center space in these metropolitan areas, our return on invested capital is negatively impacted. Our development activities make us particularly susceptible to general economic slowdowns, including recessions and the other circumstances described above under “Global market and economic conditions,” as well as adverse developments in the corporate data center, Internet and data communications and broader technology industries. Any such slowdown or adverse development could lead to reduced corporate IT spending or reduced demand for data center space. Reduced demand could also result from business relocations, including to metropolitan areas that we do not currently serve. Changes in industry practice or in technology, such as virtualization technology, more efficient computing or networking devices, or devices that require higher power densities than today’s devices, could also reduce demand for the physical data center space we provide or make the tenant improvements in our facilities obsolete or in need of significant upgrades to remain viable. In addition, the development of new technologies, the adoption of new industry standards or other factors could render many of our customers’ current products and services obsolete or unmarketable and contribute to a downturn in their businesses, thereby increasing the likelihood that they default under their leases, become insolvent or file for bankruptcy. In addition, demand for data center space, or the rates at which we lease space, may be adversely impacted either across our portfolio or in specific metropolitan areas as a result of an increase in the number of competitors, or the amount of space being offered in our metropolitan areas and other metropolitan areas by our competitors.
Critical Accounting Policies
Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses in the reporting period. Our actual results may differ from these estimates. We have provided a summary of our significant accounting policies in Item 1, Note 2 “Summary of Significant Accounting Policies” in the Notes to Condensed Consolidated Financial Statements. We describe below those accounting policies that require material subjective or complex judgments and that have the most significant impact on our financial condition and consolidated results of operations. Our management evaluates these estimates on an ongoing basis, based upon information currently available and on various assumptions management believes are reasonable as of the date on the front cover of this report.
Investments in Real Estate
Acquisition of real estate. The price that we pay to acquire a property is impacted by many factors including the condition of the property and improvements, the occupancy of the building, the term and rate of in-place leases, the creditworthiness of the customers, favorable or unfavorable financing, above- or below-market ground leases and numerous other factors.
Accordingly, we are required to make subjective assessments to allocate the purchase price paid to acquire investments in real estate among the identifiable assets including intangibles and liabilities assumed based on our estimate of the fair value of such assets and liabilities. This includes determining the value of the property and improvements, land, ground leases, if any, and tenant improvements. Additionally, we evaluate the value of in-place leases on occupancy and market rent, the value of the tenant relationships, the value (or negative value) of above (or below) market leases, any debt or deferred taxes assumed from the seller or loans made by the seller to us and any building leases assumed from the seller. Each of these estimates requires a great deal of judgment and some of the estimates involve complex calculations. These allocation assessments have a direct impact on our results of operations. For example, if we were to allocate more value to land, there would be no depreciation with respect to such amount. If we were to allocate more value to the property as opposed to allocating to the value of in-place tenant leases, this amount would be recognized as an expense over a much longer period of time. This potential effect occurs because the amounts allocated to property are depreciated over the estimated lives of the property whereas amounts allocated to in-place tenant leases are amortized over the estimated term (including renewal and extension assumptions) of the leases. Additionally, the amortization of the value (or negative value) assigned to above (or below) market rate leases is recorded as an

63


adjustment to rental revenue as compared to amortization of the value of in-place tenant leases and tenant relationships, which is included in depreciation and amortization in our consolidated income statements.
From time to time, we will receive offers from third parties to purchase our properties, either solicited or unsolicited. For those offers that we accept, the prospective buyers will usually require a due diligence period before consummation of the transactions. It is not unusual for matters to arise that result in the withdrawal or rejection of the offer during this process. We classify real estate as “held for sale” when all criteria under the GAAP guidance have been met.
Useful lives of assets. We are required to make subjective assessments as to the useful lives of our properties for purposes of determining the amount of depreciation to record on an annual basis with respect to our investments in real estate. These assessments have a direct impact on our net income because if we were to shorten the expected useful lives of our investments in real estate we would depreciate such investments over fewer years, resulting in more depreciation expense and lower net income on an annual basis.
Asset impairment evaluation. We review each of our properties for indicators that its carrying amount may not be recoverable. Examples of such indicators may include a significant decrease in the market price of the property, a change in the expected holding period for the property, a significant adverse change in how the property is being used or expected to be used based on the underwriting at the time of acquisition, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of the property, or a history of operating or cash flow losses of the property. When such impairment indicators exist, we review an estimate of the future undiscounted net cash flows (excluding interest charges) expected to result from the real estate investment’s use and eventual disposition and compare that estimate to the carrying value of the property. We consider factors such as future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If our future undiscounted net cash flow evaluation indicates that we are unable to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property. These losses have a direct impact on our net income because recording an impairment loss results in an immediate negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. Since cash flows on properties considered to be long-lived assets to be held and used are considered on an undiscounted basis to determine whether the carrying value of a property is recoverable, our strategy of holding properties over the long-term directly decreases the likelihood of their carrying values not being recoverable and therefore requiring the recording of an impairment loss. If our strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized and such loss could be material. If we determine that the asset fails the recoverability test, the affected assets must be reduced to their fair value.
We generally estimate the fair value of rental properties utilizing a discounted cash flow analysis that includes projections of future revenues, expenses and capital improvement costs that a market participant would use based on the highest and best use of the asset, which is similar to the income approach that is commonly utilized by appraisers. In certain cases, we may supplement this analysis by obtaining outside broker opinions of value.

Goodwill impairment evaluation. We perform an annual impairment test for goodwill and between annual tests, we evaluate goodwill for impairment whenever events or changes in circumstances occur that would more likely than not reduce the fair value of a reporting unit below its carrying value.  In our impairment tests of goodwill, we first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value.  If based on this assessment, we determine that the fair value of the reporting unit is not less than its carrying value, then performing the additional two-step impairment test is unnecessary. If our qualitative assessment indicates that goodwill impairment is more likely than not, we perform a two-step impairment test. We test goodwill for impairment under the two-step impairment test by first comparing the book value of net assets including goodwill to the fair value of the reporting unit. If the fair value is determined to be less than the book value of the net assets, including goodwill, a second step is performed to compute the amount of impairment as the difference between the implied fair value of goodwill and its carrying value. We estimate the fair value of the reporting units using discounted cash flows. If the carrying value of goodwill exceeds its implied fair value, an impairment charge is recognized. 
Revenue Recognition
The majority of our revenue is derived from lease arrangements, which we account for in accordance with “Leases (Topic 840)”. We account for the non-lease components within our lease arrangements, as well as other sources of revenue, in accordance with “Revenue from Contracts with Customers (Topic 606)”. Revenue recognized as a result of applying Topic 840 was 97% and Topic 606 was 3% of total operating revenue for the nine months ended September 30, 2018.

64


Our leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the terms of the leases, which may span multiple years. The excess of rents recognized over amounts contractually due pursuant to the underlying leases is included in deferred rent in the accompanying condensed consolidated balance sheets and contractually due but unpaid rents are included in accounts and other receivables.
Tenant reimbursements for real estate taxes, common area maintenance, and other recoverable costs under our leases are recognized in the period that the expenses are incurred. Lease termination fees are recognized over the remaining term of the lease, effective as of the date the lease modification is finalized, assuming collection is not considered doubtful. As discussed above, we recognize amortization of the value of acquired above or below-market tenant leases as a reduction of rental revenue in the case of above-market leases or an increase to rental revenue in the case of below-market leases.
We must make subjective estimates as to when our revenue is earned and the collectability of our accounts receivable related to minimum rent, deferred rent, expense reimbursements, lease termination fees and other income. We specifically analyze accounts receivable and historical bad debts, customer concentrations, customer creditworthiness and current economic trends when evaluating the adequacy of the allowance for bad debts. These estimates have a direct impact on our net revenue because a higher bad debt allowance would result in lower net revenue, and recognizing rental revenue as earned in one period versus another would result in higher or lower net revenue for a particular period.

Our property portfolio has experienced consistent and significant growth since the first property acquisition in January 2002. As a result of this growth, our period-to-period comparison of our financial performance focuses on the impact on our revenues and expenses on a stabilized portfolio basis. Our stabilized portfolio includes properties owned as of December 31, 2016 with less than 5% of total rentable square feet under development and excludes properties that were undergoing, or were expected to undergo, development activities in 2017-2018 and properties sold or contributed to joint ventures. Our pre-stabilized pool includes the results of the newly acquired operating properties, newly delivered properties that were previously under development and properties acquired as part of the DFT Merger in September 2017.
Comparison of the Three and Nine Months Ended September 30, 2018 to the Three and Nine Months Ended September 30, 2017
Portfolio
As of September 30, 2018, our portfolio consisted of 198 data centers, including 18 data centers held as investments in unconsolidated joint ventures, with an aggregate of 33.4 million rentable square feet including 3.6 million square feet of space under active development and 1.8 million square feet of space held for development compared to a portfolio consisting of 202 data centers, including nine data centers held-for-sale and 15 data centers held as investments in unconsolidated joint ventures, with an aggregate of 31.5 million rentable square feet including 2.8 million square feet of space under active development and 1.7 million square feet of space held for development as of September 30, 2017.

Stabilized rental and other services revenue decreased $1.5 million for the three months ended September 30, 2018, compared to the same period in 2017 as a result of expiring leases at certain properties in the stabilized portfolio partially offset by an increase in revenues from colocation services. Stabilized rental and other services revenue increased $7.2 million for the nine months ended September 30, 2018, compared to the same period in 2017 primarily as a result of new leasing and early renewals at our properties during the twelve months ended September 30, 2018, the largest of which was for space at 350 E. Cermak Road, 56 Marietta Street and 29A International Business Park, partially offset by expiring leases at certain properties in the stabilized portfolio. Stabilized tenant reimbursement revenue increased $3.4 million and $7.9 million for the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017, primarily due to higher utility reimbursements driven by increased power consumption and new leasing.

Pre-stabilized and other revenues increased $157.0 million and $525.3 million for the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017 primarily as a result of the properties acquired in the DFT Merger, which contributed approximately $136.5 million ($90.3 million of rental and other services revenue and $46.2 million of tenant reimbursements) and $454.4 million ($298.7 million of rental and other services revenue and $155.8 million of tenant reimbursements) to the increases, respectively, along with a contribution of $5.8 million and $17.3 million for the three and nine months ended September 30, 2018, respectively, to rental and other services revenue from 505 North Railroad Avenue, which was acquired in December 2017, and new leases at our properties during the twelve months ended September 30, 2018. These increases were offset partially by a decrease in revenues as a result of properties sold during the twelve months ended September 30, 2018.

Stabilized rental property operating and maintenance expenses increased approximately $5.9 million and $7.2 million in the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017. The increase was primarily related to higher utility costs offset by reduced labor costs and cost containment measures across the portfolio.
Stabilized property taxes decreased by approximately $0.8 million and $3.1 million in the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017. The decrease was primarily due to a refund at one of our properties in our stabilized portfolio.
Pre-stabilized and other rental property operating and maintenance expenses increased by approximately $50.0 million and $160.6 million in the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017 primarily as a result of the properties acquired in the DFT Merger, which contributed approximately $39.1 million and $129.0 million, respectively.
Pre-stabilized and other property tax expense increased approximately $3.1 million and $12.8 million in the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017, primarily as a result of the properties acquired in the DFT Merger, which contributed approximately $4.7 million and $15.1 million, respectively, offset partially by a reduction in property tax liabilities at certain properties in our London metropolitan area.

Depreciation and Amortization

Depreciation and amortization expense increased by approximately $94.0 million and $333.0 million in the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017, principally because of the properties acquired in the DFT Merger, which contributed approximately $89.8 million and $303.8 million, respectively, along with depreciation on development projects that were placed into service during the twelve months ended September 30, 2018.

General and Administrative

General and administrative expenses decreased by approximately $2.1 million and increased by approximately $8.3 million in the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017. The decrease for the three-month period is primarily due to higher severance payments in 2017 as compared to 2018. The increase for the nine-month period is primarily due to an increase in headcount from 2017 to 2018 to support the Company's continued growth.


68


Transactions and Integration Expenses

Transactions and integration expense decreased by approximately $33.2 million and $41.0 million in the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017, principally due to expenses incurred for the DFT Merger, which was completed in September 2017.

Interest Expense

Interest expense increased by approximately $9.2 million and $52.0 million in the three and nine months ended September 30, 2018, respectively, compared to the same periods in 2017, primarily due to the issuance of the 2019 Notes in May 2017, the issuance of the 2.750% 2024 Notes and the 2029 Notes in July 2017, the issuance of the 2.750% 2023 Notes and the 2027 Notes in August 2017 and the issuance of the 2028 Notes in June 2018.

Other Income (Expense)

Gain on Sale of Properties

During the nine months ended September 30, 2018, we recognized a gain on sale of properties of $80.0 million primarily related to the disposition of (i) 200 Quannapowitt Parkway, which sold for $15.0 million in January 2018, (ii) 34551 Ardenwood Boulevard, which sold for $73.3 million in February 2018, (iii) 3065 Gold Camp Drive, which sold for $14.2 million in March 2018, (iv) 11085 Sun Center Drive, which sold for $36.8 million in March 2018, (v) the Austin Portfolio, which sold for $47.6 million in April 2018, (vi) 2010 East Centennial Circle, which sold for $5.5 million in May 2018, (vii) 1125 Energy Park Drive, which sold for $7.0 million in May 2018 and (viii) 360 Spear Street, which sold for $92.3 million in September 2018. During the nine months ended September 30, 2017, we recognized a gain on sale of properties of $9.8 million primarily related to the disposition of 8025 North Interstate 35, which sold for $20.2 million in August 2017.
    
Liquidity and Capital Resources of the Parent Company
In this “Liquidity and Capital Resources of the Parent Company” section and in the “Liquidity and Capital Resources of the Operating Partnership” section below, the term our “Parent Company” refers to Digital Realty Trust, Inc. on an unconsolidated basis, excluding our Operating Partnership.
Analysis of Liquidity and Capital Resources
Our Parent Company’s business is operated primarily through our Operating Partnership, of which our Parent Company is the sole general partner and which it consolidates for financial reporting purposes. Because our Parent Company operates on a consolidated basis with our Operating Partnership, the section entitled “Liquidity and Capital Resources of the Operating Partnership” should be read in conjunction with this section to understand the liquidity and capital resources of our Parent Company on a consolidated basis and how our Company is operated as a whole.

Our Parent Company issues public equity from time to time, but generally does not otherwise generate any capital itself or conduct any business itself, other than incurring certain expenses in operating as a public company which are fully reimbursed by the Operating Partnership. Our Parent Company itself does not hold any indebtedness other than guarantees of the indebtedness of our Operating Partnership and certain of its subsidiaries, and its only material asset is its ownership of partnership interests of our Operating Partnership. Therefore, the consolidated assets and liabilities and the consolidated revenues and expenses of our Parent Company and our Operating Partnership are the same on their respective financial statements, except for immaterial differences related to cash, other assets and accrued liabilities that arise from public company expenses paid by our Parent Company. However, all debt is held directly or indirectly at the Operating Partnership level. Our Parent Company’s principal funding requirement is the payment of dividends on its common and preferred stock. Our Parent Company’s principal source of funding for its dividend payments is distributions it receives from our Operating Partnership.

As the sole general partner of our Operating Partnership, our Parent Company has the full, exclusive and complete responsibility for our Operating Partnership’s day-to-day management and control. Our Parent Company causes our Operating Partnership to distribute such portion of its available cash as our Parent Company may in its discretion determine, in the manner provided in our Operating Partnership’s partnership agreement. Our Parent Company receives proceeds from its equity issuances from time to time, but is generally required by our Operating Partnership’s partnership agreement to contribute the proceeds from its equity issuances to our Operating Partnership in exchange for partnership units of our Operating Partnership.

Our Parent Company is a well-known seasoned issuer with an effective shelf registration statement filed on September 22, 2017, which allows our Parent Company to register an unspecified amount of various classes of equity securities. As

69


circumstances warrant, our Parent Company may issue equity from time to time on an opportunistic basis, dependent upon market conditions and available pricing. Any proceeds from such equity issuances would generally be contributed to our Operating Partnership in exchange for additional equity interests in our Operating Partnership. Our Operating Partnership may use the proceeds to acquire additional properties, to fund development opportunities and for general working capital purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or equity securities.

The liquidity of our Parent Company is dependent on our Operating Partnership’s ability to make sufficient distributions to our Parent Company. The primary cash requirement of our Parent Company is its payment of dividends to its stockholders. Our Parent Company also guarantees our Operating Partnership’s, as well as certain of its subsidiaries’ and affiliates’, unsecured debt. If our Operating Partnership or such subsidiaries fail to fulfill their debt requirements, which trigger Parent Company guarantee obligations, then our Parent Company will be required to fulfill its cash payment commitments under such guarantees. However, our Parent Company’s only material asset is its investment in our Operating Partnership.

We believe our Operating Partnership’s sources of working capital, specifically its cash flow from operations, and funds available under its global revolving credit facility are adequate for it to make its distribution payments to our Parent Company and, in turn, for our Parent Company to make its dividend payments to its stockholders. However, we cannot assure you that our Operating Partnership’s sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including making distribution payments to our Parent Company. The lack of availability of capital could adversely affect our Operating Partnership’s ability to pay its distributions to our Parent Company, which would in turn, adversely affect our Parent Company’s ability to pay cash dividends to its stockholders.
Our Parent Company entered into equity distribution agreements in June 2011, which we refer to as the 2011 Equity Distribution Agreements, with each of Merrill Lynch, Pierce, Fenner & Smith Incorporated, Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Deutsche Bank Securities Inc. and Morgan Stanley & Co. LLC, or the Agents, under which it can issue and sell shares of its common stock having an aggregate offering price of up to $400.0 million from time to time through, at its discretion, any of the Agents as its sales agents. The sales of common stock made under the 2011 Equity Distribution Agreements were, and will be, made in “at the market” offerings as defined in Rule 415 of the Securities Act. Cumulatively through September 30, 2018, Digital Realty Trust, Inc. has generated net proceeds of approximately $342.7 million from the issuance of approximately 5.7 million common shares under the 2011 Equity Distribution Agreements at an average price of $60.35 per share after payment of approximately $3.5 million of commissions to the sales agents and before offering expenses. No sales were made under the program during the nine months ended September 30, 2018 and 2017. As of September 30, 2018, shares of common stock having an aggregate offering price of $53.8 million remained available for offer and sale under the program.

On June 21, 2018, the Operating Partnership issued $650.0 million in aggregate principal amount of notes, maturing on July 15, 2028 with an interest rate of 4.450% per annum, which we refer to as the 2028 Notes. The purchase price paid by the initial purchasers was 99.852% of the principal amount. The 2028 Notes are general unsecured senior obligations of the Operating Partnership, rank equally in right of payment with all other senior unsecured indebtedness of the Operating Partnership and are fully and unconditionally guaranteed by our Parent Company. Interest on the 2028 Notes is payable on January 15 and July 15 of each year, beginning on January 15, 2019. The net proceeds from the offering after deducting the original issue discount of approximately $1.0 million and underwriting commissions and expenses of approximately $5.7 million was approximately $643.3 million. We used the net proceeds from this offering to temporarily repay borrowings under our global revolving credit facility and for general corporate purposes.

On September 27, 2018, our Parent Company completed an underwritten public offering of 9,775,000 shares of its common stock (including 1,275,000 shares from the exercise in full of the underwriters' option to purchase additional shares), all of which were offered in connection with forward sale agreements it entered into with certain financial institutions acting as forward purchasers. The forward purchasers borrowed and sold an aggregate of 9,775,000 shares of our Parent Company’s common stock in the public offering. We did not receive any proceeds from the sale of our common stock by the forward purchasers in the public offering. We expect to receive net proceeds of approximately $1.1 billion (net of fees and estimated expenses) upon full physical settlement of the forward sale agreements, which is anticipated to be no later than September 27, 2019.

On October 17, 2018, Digital Stout Holding, LLC, a wholly owned subsidiary of the Operating Partnership, issued and sold £400.0 million (approximately $524.6 million based on the exchange rate on October 17, 2018) aggregate principal amount of 3.750% Guaranteed Notes due 2030, or the 2030 Notes. The 2030 Notes are senior unsecured obligations of Digital Stout Holding, LLC and are fully and unconditionally guaranteed by the Parent Company and the Operating Partnership. Net proceeds from the offering were approximately £393.5 million (approximately $516.1 million based on the exchange rate on October 17, 2018) after deducting managers’ discounts and estimated offering expenses. We intend to use the net proceeds from

70


the offering of the 2030 Notes to repay borrowings outstanding under the Operating Partnership’s global credit facilities, acquire additional properties or businesses, fund development opportunities, and to provide for working capital and other general corporate purposes, including potentially for the repayment of other debt or the repurchase, redemption, or retirement of outstanding debt securities, or a combination of the foregoing.
Future Uses of Cash
Our Parent Company may from time to time seek to retire, redeem or repurchase its equity or the debt securities of our Operating Partnership or its subsidiaries through cash purchases and/or exchanges for equity securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases, redemptions or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions or other factors. The amounts involved may be material.
We are also subject to the commitments discussed below under “Dividends and Distributions.”
Dividends and Distributions
Our Parent Company is required to distribute 90% of its taxable income (excluding capital gains) on an annual basis in order for it to continue to qualify as a REIT for federal income tax purposes. Accordingly, our Parent Company intends to make, but is not contractually bound to make, regular quarterly distributions to its common stockholders from cash flow from our Operating Partnership’s operating activities. While historically our Parent Company has satisfied this distribution requirement by making cash distributions to its stockholders, it may choose to satisfy this requirement by making distributions of cash or other property. All such distributions are at the discretion of our Parent Company’s board of directors. Our Parent Company considers market factors and our Operating Partnership’s performance in addition to REIT requirements in determining distribution levels. Our Parent Company has distributed at least 100% of its taxable income annually since inception to minimize corporate level federal income taxes. Amounts accumulated for distribution to stockholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, which are consistent with our intention to maintain our Parent Company’s status as a REIT.
As a result of this distribution requirement, our Operating Partnership cannot rely on retained earnings to fund its on-going operations to the same extent that other companies whose parent companies are not REITs can. Our Parent Company may need to continue to raise capital in the debt and equity markets to fund our Operating Partnership’s working capital needs, as well as potential developments at new or existing properties, acquisitions or investments in existing or newly created joint ventures. In addition, our Parent Company may be required to use borrowings under our global revolving credit facility, if necessary, to meet REIT distribution requirements and maintain our Parent Company’s REIT status.

Our Parent Company has declared and paid the following dividends on its common and preferred stock for the nine months ended September 30, 2018 (in thousands, except per share amounts):

Distributions out of our Parent Company’s current or accumulated earnings and profits are generally classified as ordinary income whereas distributions in excess of our Parent Company’s current and accumulated earnings and profits, to the extent of a stockholder’s U.S. federal income tax basis in our Parent Company’s stock, are generally classified as a return of capital. Distributions in excess of a stockholder’s U.S. federal income tax basis in our Parent Company’s stock are generally characterized as capital gain. Cash provided by operating activities has been generally sufficient to fund distributions on an annual basis, however, we may also need to utilize borrowings under the global revolving credit facility to fund distributions.

Liquidity and Capital Resources of the Operating Partnership
In this “Liquidity and Capital Resources of the Operating Partnership” section, the terms “we”, “our” and “us” refer to our Operating Partnership together with its consolidated subsidiaries or our Operating Partnership and our Parent Company together with their consolidated subsidiaries, as the context requires.
Analysis of Liquidity and Capital Resources
Our Parent Company is our sole general partner and consolidates our results of operations for financial reporting purposes. Because we operate on a consolidated basis with our Parent Company, the section entitled “Liquidity and Capital Resources of the Parent Company” should be read in conjunction with this section to understand our liquidity and capital resources on a consolidated basis.
As of September 30, 2018, we had $46.2 million of cash and cash equivalents, excluding $8.1 million of restricted cash. Restricted cash primarily consists of contractual capital expenditures plus other deposits.

Our short-term liquidity requirements primarily consist of operating expenses, development costs and other expenditures associated with our properties, distributions to our Parent Company in order for it to make dividend payments on its preferred stock, distributions to our Parent Company in order for it to make dividend payments to its stockholders required to maintain its REIT status, distributions to the unitholders of common limited partnership interests in Digital Realty Trust, L.P., capital expenditures, debt service on our loans and senior notes, and, potentially, acquisitions. We expect to meet our short-term liquidity requirements through net cash provided by operations, restricted cash accounts established for certain future payments and by drawing upon our global revolving credit facility.

On January 15, 2016, we refinanced our global revolving credit facility and entered into a global senior credit agreement for a $2.0 billion senior unsecured revolving credit facility, which we refer to as the global revolving credit facility, that replaced the $2.0 billion revolving credit facility executed on August 15, 2013, as amended. The global revolving credit facility has an accordion feature that enables us to increase the borrowing capacity of the credit facility to up to $2.5 billion, subject to the receipt of lender commitments and other conditions precedent. The refinanced facility matures on January 15, 2020, with two six-month extension options available. The interest rate for borrowings under the global revolving credit facility equals the applicable index plus a margin which is based on the credit ratings of our long-term debt and is currently 100 basis points. An annual facility fee on the total commitment amount of the facility, based on the credit ratings of our long-term debt, currently 20 basis points, is payable quarterly. Funds may be drawn in U.S., Canadian, Singapore, Australian and Hong Kong dollars, as well as Euro, British pound sterling and Japanese yen. As of September 30, 2018, borrowings under the global revolving credit facility bore interest at an overall blended rate of 2.35% comprised of 3.23% (U.S. dollars), 0.62% (Euro), 2.85% (Australian dollars), 2.91% (Hong Kong dollars), 0.90% (Japanese yen), 2.61% (Singapore dollars) and 2.82% (Canadian dollars). The interest rates are based on 1-month LIBOR, 1-month EURIBOR, 1-month BBR, 1-month HIBOR, 1-month JPY LIBOR, 1-month SOR and 1-month CDOR, respectively, plus a margin of 1.00%. We have used and intend to use available borrowings under the global revolving credit facility to acquire additional properties, fund development opportunities and for general working capital and other corporate purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or equity securities. As of September 30, 2018, we have capitalized approximately $4.7 million of financing costs, net of accumulated amortization, related to the global revolving credit facility. As of September 30, 2018, approximately $595.0 million was drawn under the global revolving credit facility and $44.6 million of letters of credit were issued, leaving approximately $1.4 billion available for use.

On January 15, 2016, we refinanced the senior unsecured multi-currency term loan facility and entered into a term loan agreement, which governs (i) a $1.25 billion 5-year senior unsecured term loan, which we refer to as the 5-Year Term Loan, and (ii) a $300 million 7-year senior unsecured term loan, which we refer to as the 7-Year Term Loan. The 2016 term loan agreement replaced the $1.0 billion term loan agreement executed on April 16, 2012, as amended. The 5-Year Term Loan matures on January 15, 2021 and the 7-Year Term Loan matures on January 15, 2023. In addition, we have the ability from time to time to increase the aggregate size of lending under the 2016 term loan agreement from $1.55 billion to up to $1.8 billion, subject to receipt of lender commitments and other conditions precedent. Interest rates are based on our senior unsecured debt ratings and are currently 110 basis points and 155 basis points over the applicable index for floating rate advances for the 5-Year Term Loan and the 7-Year Term Loan, respectively. Funds may be drawn in U.S., Canadian, Singapore, Australian and Hong Kong dollars, as well as Euro, British pound sterling and Japanese yen. Based on exchange rates in effect at September 30, 2018, the balance outstanding is approximately $1.4 billion, excluding deferred financing costs. We have used borrowings under the term loans for acquisitions, repayment of indebtedness, development, working capital and general corporate purposes. As of September 30, 2018, we have capitalized approximately $3.7 million of financing costs, net of accumulated amortization, related to the 2016 unsecured term loans.

On June 21, 2018, we issued $650.0 million in aggregate principal amount of notes, maturing on July 15, 2028 with an interest rate of 4.450% per annum, which we refer to as the 2028 Notes. The purchase price paid by the initial purchasers was 99.852% of the principal amount. The 2028 Notes are our general unsecured senior obligations, rank equally in right of payment with all our other senior unsecured indebtedness of the and are fully and unconditionally guaranteed by Digital Realty Trust, Inc. Interest on the 2028 Notes is payable on January 15 and July 15 of each year, beginning on January 15, 2019. The net proceeds from the offering after deducting the original issue discount of approximately $1.0 million and underwriting commissions and expenses of approximately $5.7 million was approximately $643.3 million. We used the net proceeds from this offering to temporarily repay borrowings under our global revolving credit facility and for general corporate purposes.

On October 17, 2018, Digital Stout Holding, LLC, a wholly owned subsidiary of the Operating Partnership, issued and sold £400.0 million (approximately $524.6 million based on the exchange rate on October 17, 2018) aggregate principal amount of 3.750% Guaranteed Notes due 2030, or the 2030 Notes. The 2030 Notes are senior unsecured obligations of Digital Stout Holding, LLC and are fully and unconditionally guaranteed by the Parent Company and the Operating Partnership. Net proceeds from the offering were approximately £393.5 million (approximately $516.1 million based on the exchange rate on October 17, 2018) after deducting managers’ discounts and estimated offering expenses. We intend to use the net proceeds from the offering of the 2030 Notes to repay borrowings outstanding under the Operating Partnership’s global credit facilities, acquire additional properties or businesses, fund development opportunities, and to provide for working capital and other general corporate purposes, including potentially for the repayment of other debt or the repurchase, redemption, or retirement of outstanding debt securities, or a combination of the foregoing.

On October 24, 2018, we refinanced our global revolving credit facility and entered into a global senior credit agreement for a $2.35 billion senior unsecured revolving credit facility, which we refer to as the 2018 global revolving credit facility, that replaced the $2.0 billion revolving credit facility executed on January 15, 2016. The 2018 global revolving credit facility provides for borrowings in Australian dollars, British pounds sterling, Canadian dollars, Euros, Hong Kong dollars, Japanese yen, Singapore dollars, and U.S. dollars, and includes the ability to add additional currencies in the future. The 2018 global revolving credit facility matures on January 24, 2023 with two six-month extension options. In addition, we have the ability from time to time to increase the size of the global revolving credit facility and the unsecured term loans (discussed below), in any combination, by up to $1.25 billion, subject to receipt of lender commitments and other conditions precedent.

On October 24, 2018, we refinanced our senior unsecured multi-currency term loan facility and entered into an amended and restated term loan agreement, which we refer to as the 2018 term loan agreement, which governs (i) a $300.0 million 5-year senior unsecured term loan, which we refer to as the 2023 Term Loan and (ii) an approximately $512.0 million 5-year senior unsecured term loan, which we refer to as the 2024 Term Loan. The 2018 term loan agreement replaced the $1.55 billion term loan agreement executed on January 15, 2016. The 2018 term loan agreement provides for borrowings in Australian dollars, Canadian dollars, Hong Kong dollars, Singapore dollars and U.S. dollars. In addition, we have the ability from time to time to increase the aggregate size of lending under the 2018 term loan agreement and the global revolving credit facility (discussed above), in any combination, by up to $1.25 billion, subject to receipt of lender commitments and other conditions precedent. The maturity date of the 2023 Term Loan is January 15, 2023. The maturity date of the 2024 Term Loan is January 24, 2023 with two six-month extension options.

On October 24, 2018, we entered into a credit agreement for a ¥33.3 billion (approximately $296.5 million based on the exchange rate on October 24, 2018) senior unsecured revolving credit facility, which we refer to as the Yen revolving credit facility. The Yen revolving credit facility provides for borrowings in Japanese yen. In addition, we have the ability from time to time to increase the size of the Yen revolving credit facility to up to ¥93.3 billion (approximately $831.1 million based on the exchange rate on October 24, 2018), subject to receipt of lender commitments and other conditions precedent. The Yen revolving credit facility matures on January 24, 2024.

On October 24, 2018, the Operating Partnership, together with its subsidiary Quill Equity LLC as borrowers, entered into Amendment No. 1 to the Senior Secured Term Loan, which we refer to (as so amended) as the secured term loan agreement, which among other things amended the financial covenants therein to correspond with the financial covenants in the 2018 global senior credit agreement and the 2018 term loan agreement, decreased the applicable rate for eurodollar rate advances, and decreased the applicable rate for base rate advances. As of October 24, 2018, the applicable rate for eurodollar rate advances is the applicable index plus 100 basis points and the applicable rate for base rate advances is the applicable index plus 0 basis points. An annual agency fee is payable quarterly in respect of the commitments under the secured term loan agreement. We are also required to pay certain fees to the administrative agent under the secured term loan agreement.

For a discussion of the potential impact of current global economic and market conditions on our liquidity and capital resources, see “—Factors Which May Influence Future Results of Operations—Global market and economic conditions” above.
Our Parent Company commenced its At-the-Market equity distribution program in June 2011, which is discussed under “Liquidity and Capital Resources of the Parent Company” above. To date, our Parent Company has generated net proceeds of approximately $342.7 million from the issuance of approximately 5.7 million shares of common stock under the program at an average price of $60.35 per share after payment of approximately $3.5 million of commissions to the sales agents before offering expenses. The proceeds from the issuances were contributed to us in exchange for the issuance of approximately 5.7 million common units to our Parent Company. No sales were made under the program during the nine months ended September 30, 2018 and 2017. As of September 30, 2018, shares of common stock having an aggregate offering price of $53.8 million remained available for offer and sale under the program.

The growing acceptance by private institutional investors of the data center asset class has generally pushed capitalization rates lower, as such private investors may often have lower return expectations than us. As a result, we anticipate near-term single asset acquisitions activity to comprise a smaller percentage of our growth while this market dynamic persists.

Land inventory and space held for development reflect cumulative cost spent pending future development. Base building construction consists of ongoing improvements to building infrastructure in preparation for future datacenter fit-out. Data center construction includes 1.6 million square feet of Turn Key Flex® and Powered Base Building® product with a cost to date of approximately $806.0 million. Generally, we expect to deliver the space within 12 months; however, lease commencement dates may significantly impact final delivery schedules. Equipment pool and other inventory represent the value of long-lead equipment and materials required for timely deployment and delivery of datacenter construction fit-out. Campus, tenant

improvements and other costs include the value of development work which benefits space recently converted to our operating portfolio and is composed primarily of shared infrastructure projects and first-generation tenant improvements.
Future Uses of Cash
Our properties require periodic investments of capital for tenant-related capital expenditures and for general capital improvements. As of September 30, 2018, we had approximately 3.6 million square feet of space under active development and approximately 1.8 million square feet of space held for development. Turn-Key Flex® space is move-in-ready space for the placement of computer and network equipment required to provide a data center environment. Depending on demand for additional Turn-Key Flex® space, we expect to incur significant tenant improvement costs to build out and develop these types of spaces. At September 30, 2018, the approximate 3.6 million square feet of space under active development was under construction for Turn-Key Flex® and Powered Base Building® products, all of which are expected to be income producing on or after completion, in seven U.S. metropolitan areas, four European metropolitan areas, three Asian metropolitan areas, two Australian metropolitan areas and one Canadian metropolitan area, consisting of approximately 2.0 million square feet of base building construction and 1.6 million square feet of data center construction. At September 30, 2018, we had open commitments, including amounts reimbursable of approximately $5.7 million, related to construction contracts of approximately $428.3 million.
We currently expect to incur approximately $0.2 billion to $0.4 billion of capital expenditures for our development programs during the three months ending December 31, 2018, although this amount may increase or decrease, potentially materially, based on numerous factors, including changes in demand, leasing results and availability of debt or equity capital.

On September 21, 2018, a subsidiary of the Operating Partnership entered into a definitive agreement to acquire Ascenty, a leading data center provider in Brazil, from private equity firm Great Hill Partners in a transaction valued at approximately $1.8 billion. The transaction is expected to close in the fourth quarter of 2018 and is subject to customary closing conditions. We separately entered into an independent bilateral equity commitment letter with Brookfield Infrastructure, an affiliate of Brookfield Asset Management, one of the largest owners and operators of infrastructure assets globally, under which Brookfield has committed to fund half of the required initial equity investment, currently estimated to be approximately $0.6 billion, excluding Brookfield’s share of the transaction costs, in exchange for 49% of the total equity interests in a joint venture entity expected to ultimately own Ascenty. The closing of Brookfield's investment in the joint venture entity is subject to customary closing conditions and receipt by Brookfield of Brazilian regulatory approvals and is expected to close by the first quarter of 2019. The Operating Partnership intends to fund its portion of the acquisition of Ascenty, including transaction expenses, with net proceeds contributed by the Parent Company from the settlement of the forward sale agreements. Our Operating Partnership intends to use the balance of such net proceeds, if any, to repay borrowings outstanding under its global revolving credit facility and for general corporate purposes, including, the repayment of other outstanding indebtedness, the repurchase, redemption or retirement of outstanding debt or preferred equity securities, future capital contributions to the joint venture and the funding of development and acquisition opportunities.

Historical Capital Expenditures (Cash Basis)

For the nine months ended September 30, 2018, total capital expenditures increased $171.6 million to approximately $866.1 million from $694.5 million for the same period in 2017. Capital expenditures on our development projects plus our enhancement and improvements projects for the nine months ended September 30, 2018 were approximately $781.8 million, which reflects an increase of approximately 30% from the same period in 2017. This increase was primarily due to increased spending for ground-up development projects (including development projects acquired in the DFT Merger), Turn-Key Flex space development and base building improvements. Our development capital expenditures are generally funded by our available cash and equity and debt capital.

75


Indirect costs, including capitalized interest, capitalized in the nine months ended September 30, 2018 and 2017 were $80.0 million and $69.4 million, respectively. Capitalized interest comprised approximately $25.3 million and $13.7 million, respectively, of the total indirect costs capitalized for the nine months ended September 30, 2018 and 2017. Capitalized interest in the nine months ended September 30, 2018 increased compared to the same period in 2017 due to an increase in qualifying activities. Excluding capitalized interest, indirect costs in the nine months ended September 30, 2018 increased compared to the same period in 2017 due primarily to capitalized amounts relating to compensation expense of employees directly engaged in construction activities. See “—Future Uses of Cash” above for a discussion of the amount of capital expenditures we expect to incur during the year ending December 31, 2018.
We are also subject to the commitments discussed below under “Commitments and Contingencies,” “Off-Balance Sheet Arrangements” and “Distributions.”
Consistent with our growth strategy, we actively pursue opportunities for potential acquisitions, with due diligence and negotiations often at different stages at different times. The dollar value of acquisitions for the year ending December 31, 2018 will be based on numerous factors, including tenant demand, leasing results, availability of debt or equity capital and acquisition opportunities.
We may from time to time seek to retire or repurchase our outstanding debt or the equity of our Parent Company through cash purchases and/or exchanges for equity securities of our Parent Company in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions or other factors. The amounts involved may be material.
We expect to meet our short-term and long-term liquidity requirements, including to pay for scheduled debt maturities and to fund acquisitions and non-recurring capital improvements, with net cash from operations, future long-term secured and unsecured indebtedness and the issuance of equity and debt securities and the proceeds of equity issuances by our Parent Company. We also may fund future short-term and long-term liquidity requirements, including acquisitions and non-recurring capital improvements, using our global revolving credit facility pending permanent financing. If we are not able to obtain additional financing on terms attractive to us, or at all, including as a result of the circumstances described above under “Factors Which May Influence Future Results of Operations—Global market and economic conditions”, we may be required to reduce our acquisition or capital expenditure plans, which could have a material adverse effect upon our business and results of operations.

Excludes impact of deferred financing cost amortization.
As of September 30, 2018, we had approximately $9.2 billion of outstanding consolidated long-term debt as set forth in the table above, which excludes deferred financing costs. Our ratio of debt to total enterprise value was approximately 27% (based on the closing price of Digital Realty Trust, Inc.’s common stock on September 30, 2018 of $112.48). For this purpose, our total enterprise value is defined as the sum of the market value of Digital Realty Trust, Inc.’s outstanding common stock (which may decrease, thereby increasing our debt to total enterprise value ratio), plus the liquidation value of Digital Realty Trust, Inc.’s preferred stock, plus the aggregate value of our Operating Partnership’s units not held by Digital Realty Trust, Inc. (with the per unit value equal to the market value of one share of Digital Realty Trust, Inc.’s common stock and excluding long-term incentive units, Class C units and Class D units), plus the book value of our total consolidated indebtedness.
The variable rate debt shown above bears interest at interest rates based on various one-month LIBOR, EURIBOR, GBP LIBOR, SOR, BBR, HIBOR, JPY LIBOR and CDOR rates, depending on the respective agreement governing the debt, including our global revolving credit facility and unsecured term loans. As of September 30, 2018, our debt had a weighted average term to initial maturity of approximately 5.0 years (or approximately 5.1 years assuming exercise of extension options).

Off-Balance Sheet Arrangements
As of September 30, 2018, we were party to interest rate swap agreements related to $1.0 billion of outstanding principal on our variable rate debt. See Item 3. “Quantitative and Qualitative Disclosures about Market Risk.”
As of September 30, 2018, our pro-rata share of mortgage debt of unconsolidated joint ventures was approximately $264.5 million, of which $10.2 million is subject to interest rate swap agreements.

The increase in cash used in financing activities was due to repayments of borrowings, net of proceeds, decreasing during the nine months ended September 30, 2018 as compared to the nine months ended September 30, 2017 offset by higher proceeds in 2017 from the issuance of the 2019 Notes, 2.750% 2024 Notes, 2029 Notes, 2.750% 2023 Notes and 2027 Notes as compared to the proceeds in 2018 from the issuance of the 2028 Notes. The increase in dividend and distribution payments for the nine months ended September 30, 2018 as compared to the same period in 2017, which was a result of an increase in the number of shares outstanding due to the DFT Merger and increased dividend amount per share of common stock in the nine months ended September 30, 2018 as compared to the same period in 2017.

The increase in cash used in financing activities was due to repayments of borrowings, net of proceeds, decreasing during the nine months ended September 30, 2018 as compared to the nine months ended September 30, 2017 offset by higher proceeds in 2017 from the issuance of the 2019 Notes, 2.750% 2024 Notes, 2029 Notes, 2.750% 2023 Notes and 2027 Notes as compared to the proceeds in 2018 from the issuance of the 2028 Notes. The increase in distribution payments for the nine months ended September 30, 2018 as compared to the same period in 2017, which was a result of an increase in the number of units outstanding due to the DFT Merger and increased distribution amount per common unit in the nine months ended September 30, 2018 as compared to the same period in 2017.
Noncontrolling Interests in Operating Partnership
Noncontrolling interests relate to the common units in our Operating Partnership that are not owned by Digital Realty Trust, Inc., which, as of September 30, 2018, amounted to 3.9% of our Operating Partnership common units. Historically, our Operating Partnership has issued common units to third party sellers in connection with our acquisition of real estate interests from such third parties.
Limited partners have the right to require our Operating Partnership to redeem part or all of their common units for cash based upon the fair market value of an equivalent number of shares of Digital Realty Trust, Inc. common stock at the time of the redemption. Alternatively, we may elect to acquire those common units in exchange for shares of Digital Realty Trust, Inc. common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events. In connection with the DFT Merger, approximately 0.2 million common units of the Operating Partnership were issued to certain former unitholders in DuPont Fabros Technology, L.P., which are subject to certain restrictions and, accordingly, are not presented as permanent capital in the condensed consolidated balance sheet.
Inflation
Many of our leases provide for separate real estate tax and operating expense escalations. In addition, many of the leases provide for fixed base rent increases. We believe that inflationary increases may be at least partially offset by the contractual rent increases and expense escalations described above.
Funds from Operations

We calculate funds from operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts, or NAREIT. FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of property, excluding a gain from a pre-existing relationship, impairment charges and real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions and after adjustments for unconsolidated partnerships and joint ventures, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes 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. Other REITs may not calculate FFO in accordance with the NAREIT definition and, accordingly, our FFO may not be comparable to such other REITs’ FFO. FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Our future income, cash flows and fair values relevant to financial instruments depend upon prevalent market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. We do not use derivatives for trading or speculative purposes and only enter into contracts with major financial institutions based on their credit rating and other factors.
Analysis of Debt between Fixed and Variable Rate
We use interest rate swap agreements and fixed rate debt to reduce our exposure to interest rate movements. As of September 30, 2018, our consolidated debt was as follows (in millions):

Sensitivity to Changes in Interest Rates
The following table shows the effect if assumed changes in interest rates occurred, based on fair values and interest expense as of September 30, 2018:
 
Assumed event
 
Change ($ millions)
Increase in fair value of interest rate swaps following an assumed 10% increase in interest rates
 
$
4.6

Decrease in fair value of interest rate swaps following an assumed 10% decrease in interest rates
 
(4.6

Increase in annual interest expense on our debt that is variable rate and not subject to swapped interest following a 10% increase in interest rates

)
Increase in fair value of fixed rate debt following a 10% decrease in interest rates
 
88.8

Decrease in fair value of fixed rate debt following a 10% increase in interest rates
 
(82.6
)
Interest risk amounts were determined by considering the impact of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in overall economic activity that could occur in that environment. Further, in the event of a change of that magnitude, we may take 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.
Foreign Currency Exchange Risk
For the nine months ended September 30, 2018 and 2017, we had foreign operations in the United Kingdom, Ireland, France, Germany, the Netherlands, Switzerland, Canada, Singapore, Australia, Japan and Hong Kong. As such, we are subject to risk from the effects of exchange rate movements of foreign currencies, which may affect future costs and cash flows. Our foreign operations are conducted in the British pound sterling, Euro, Australian dollar, Singapore dollar, Canadian dollar, Hong Kong dollar and the Japanese yen. Our primary currency exposures are to the British pound sterling, Euro and the Singapore dollar. We attempt to mitigate a portion of the risk of currency fluctuation by financing our investments in the local currency denominations and we may also hedge well-defined transactional exposures with foreign currency forwards or options, although there can be no assurances that these will be effective. As a result, changes in the relation of any such foreign currency to U.S. dollars may affect our revenues, operating margins and distributions and may also affect the book value of our assets and the amount of stockholders’ equity. For the three months ended September 30, 2018 and 2017, operating revenues from properties outside the United States contributed $139.7 million and $131.7 million, respectively, which represented 18.2% and 21.6% of our total operating revenues, respectively. For the nine months ended September 30, 2018 and 2017, operating revenues from properties outside the United States contributed $421.3 million and $380.0 million, respectively, which represented 18.6% and 22.0% of our total operating revenues, respectively. Net investment in properties outside the United States was $3.3 billion and $3.1 billion as of September 30, 2018 and December 31, 2017, respectively. Net assets in foreign operations were approximately $0.2 billion and $0.3 billion as of September 30, 2018 and December 31, 2017, respectively.

ITEM 4. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures (Digital Realty Trust, Inc.)

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to its management, including its chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, the Company’s 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 its management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
