EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the quarter ended September 30, 2013 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, 2013, Digital Realty Trust, Inc. owned an approximate 97.7% common general partnership interest in Digital Realty Trust, L.P. The remaining approximate 2.3% common limited partnership interests are owned by non-affiliated investors and certain directors and officers of Digital Realty Trust, Inc. As of September 30, 2013, 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. 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, 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 of the company and Capital and Accumulated Other Comprehensive Loss of the operating partnership;

•

Liquidity and Capital Resources in Management’s Discussion and Analysis of Financial Condition and Results of Operations; and

•

Unregistered Sales of Equity Securities and Use of Proceeds.

This report also includes separate 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 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.

Digital Realty Trust, Inc. through its controlling interest in Digital Realty Trust, L.P. (the Operating Partnership) and the subsidiaries of the Operating Partnership (collectively, we, our, us, the General Partner or the Company) is engaged in the business of owning, acquiring, developing and managing technology-related real estate. The Company is focused on providing customer driven datacenter solutions for domestic and international tenants across a variety of industry verticals ranging from financial services, cloud and information technology services, to manufacturing, energy, health care and consumer products. As of September 30, 2013, our portfolio consisted of 130 properties, including 12 properties held as investments in unconsolidated joint ventures and developable land, of which 103 are located throughout North America, 22 are located in Europe, three are located in Australia and two are located in Asia. We are diversified in major markets where corporate datacenter and technology tenants are concentrated, including the Boston, Chicago, Dallas, Los Angeles, New York Metro, Northern Virginia, Phoenix, San Francisco and Silicon Valley metropolitan areas in the U.S., Amsterdam, Dublin, London and Paris markets in Europe and Singapore, Sydney, Melbourne and Osaka markets in the Asia Pacific region. The portfolio consists of Internet gateway and corporate datacenter properties, technology manufacturing properties and regional or national headquarters of technology companies.

The Operating Partnership was formed on July 21, 2004 in anticipation of Digital Realty Trust, Inc.’s initial public offering (IPO) on November 3, 2004 and commenced operations on that date. As of September 30, 2013, Digital Realty Trust, Inc. owns a 97.7% common interest and a 100% preferred interest in the Operating Partnership. As sole general partner of the Operating Partnership, Digital Realty Trust, Inc. has the full, exclusive and complete responsibility for the Operating Partnership’s day-to-day management and control. The limited partners of the Operating Partnership do not have rights to replace Digital Realty Trust, Inc. as the general partner nor do they have participating rights, although they do have certain protective rights.

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, 2012.

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. does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

(unaudited)

unsecured debt of the Operating Partnership and certain of its subsidiaries. Digital Realty Trust, Inc. itself does not hold any indebtedness but guarantees the unsecured debt of the Operating Partnership and certain of its subsidiaries, 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 generates the capital required by the Company’s business through the Operating Partnership’s operations, by the Operating Partnership’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 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.

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 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, 2013, cash equivalents consist of investments in money market instruments.

(c) Share Based Compensation

We account for share based compensation using the fair value method of accounting. The estimated fair value of restricted stock granted by us is being amortized on a straight-line basis over the vesting period. The estimated fair value of the long-term incentive units and Class C Units (discussed in note 13) granted by us is being amortized on a straight-line basis over the expected service period.

For share based compensation awards with performance conditions, we estimate the fair value of the award for each of the possible performance condition outcomes and amortize the compensation cost based on management’s projected performance outcome. In the instance management’s projected performance outcome changes prior to the final measurement date, compensation cost is adjusted accordingly.

(d) Income Taxes

Digital Realty Trust, Inc. (the Parent Company) has elected to be treated and believes that it has been organized and has operated in a manner that has enabled the Parent Company to qualify as a REIT for federal income tax purposes. As a REIT, the Parent Company generally is not required to pay federal corporate income taxes on its taxable income to the extent it is currently distributed to its stockholders.

However, qualification and taxation as a REIT depend upon the Parent Company’s ability to meet the various qualification tests imposed under the Internal Revenue Code of 1986, as amended (the Code), including tests related to annual operating results, asset composition, distribution levels and diversity of stock ownership. Accordingly, no assurance can be given that the Parent Company has been organized or has operated or will continue to operate in a manner so as to qualify or remain qualified as a REIT. If the Parent Company fails to qualify as a REIT in any taxable year, it will be subject to federal income tax (including any applicable alternative minimum tax) on its taxable income at regular corporate tax rates.

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.

Even if the Parent Company and the Operating Partnership are not subject to federal income taxes, the Company is subject to foreign, state and local income taxes in the jurisdictions in which it conducts business. The Company’s US consolidated taxable REIT subsidiary is subject to both federal and state income taxes to the extent there is taxable income. Accordingly, the Company recognizes and accrues income taxes for its taxable REIT subsidiaries, certain states 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, 2013 and December 31, 2012, we have 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, 2013 and 2012, we had no such interest or penalties. The tax years 2010 through 2012 remain open to examination by the major taxing jurisdictions with which the Parent Company and its subsidiaries file tax returns.

See Note 10 for further discussion on income taxes.

(e) 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.

(f) Asset Retirement Obligations

We record accruals for estimated retirement obligations as required by current accounting guidance. The amount of asset retirement obligations relates primarily to estimated asbestos removal costs at the end of the economic life of properties that were built before 1984. As of September 30, 2013 and December 31, 2012, the amount included in accounts payable and other accrued liabilities on our condensed consolidated balance sheets was approximately $1.7 million.

(g) Construction Management Revenue

Construction management revenue for long-term contracts is recognized under the percentage-of-completion method of accounting. Revenues are determined by measuring the percentage of total costs incurred to date to estimated total costs for each construction management contract based on current estimates of costs to complete. Contract costs include all labor and benefits, materials, subcontracts, and an allocation of indirect costs related to contract performance. Indirect costs are allocated to projects based upon labor hours charged. Third party costs are included in construction management expense and their reimbursements are included in

DIGITAL REALTY TRUST, L.P. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

September 30, 2013 and 2012

(unaudited)

construction management revenue to the extent that the Company is the primary obligor for the third party costs. Otherwise, construction management revenue and expense is reflected net of third party costs. As long-term design-build projects extend over one or more years, revisions in cost and estimated earnings during the course of the work are reflected in the accounting period in which the facts which require the revision become known. At the time a loss on a design-build project becomes known, the entire amount of the estimated loss is recognized in the condensed consolidated financial statements. Change orders are recognized when they are approved by the client.

Costs and estimated earnings in excess of billings on uncompleted construction management projects are included in other assets in the condensed consolidated balance sheets. Billings in excess of costs and estimated earnings on uncompleted construction management projects are included in accounts payable and other accrued liabilities in the condensed consolidated balance sheets. Customers are billed on a monthly basis at the end of each month, which can be in advance of work performed.

(h) 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 level in the fair-value hierarchy within which the entire fair-value measurement falls is based on the lowest level input that is significant to the fair-value measurement in its entirety. 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.

(i) Transactions Expense

Transactions expense includes acquisition-related expenses and other business development expenses, which are expensed as incurred. Acquisition-related expenses include closing costs, broker commissions and other professional fees, including legal and accounting fees related to acquisitions and potential acquisitions.

(j) 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. We cease cost capitalization if activities necessary for the development of the property have been suspended. Capitalized costs are allocated to the specific components of a project that are benefited.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

September 30, 2013 and 2012

(unaudited)

During the three months ended September 30, 2013 and 2012, we capitalized interest of approximately $6.9 million and $4.5 million, respectively, and $18.8 million and $13.6 million during the nine months ended September 30, 2013 and 2012, respectively. During the three months ended September 30, 2013 and 2012, we capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $9.7 million and $8.0 million, respectively, and $29.4 million and $23.3 million during the nine months ended September 30, 2013 and 2012, respectively. Cash flows from capitalized leasing costs of $36.4 million and $26.5 million are included in improvements to and advances for investments in real estate in cash flows from investing activities in the consolidated statements of cash flows for the nine months ended September 30, 2013 and 2012, respectively.

(k) 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 condensed 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, contingent consideration, accounts receivable and deferred rent receivable, performance-based equity compensation plans, the completeness of accrued liabilities and Digital Realty Trust, Inc.’s qualification as a REIT. 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.

(l) Segment and Geographic Information

All of our properties generate similar revenues and expenses related to tenant rent and reimbursements and operating expenses. The 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. Consequently, our properties qualify for aggregation into one reporting segment.

Operating revenues from properties in the United States were $294.1 million and $270.2 million and outside the United States were $85.4 million and $72.3 million for the three months ended September 30, 2013 and 2012, respectively. Operating revenues from properties in the United States were $845.0 million and $778.3 million and outside the United States were $256.3 million and $151.0 million for the nine months ended September 30, 2013 and 2012, respectively. We had long-lived assets located in the United States of $5.4 billion and $5.0 billion and outside the United States of $2.6 billion and $2.5 billion as of September 30, 2013 and December 31, 2012, respectively.

Operating revenues from properties located in England were $48.0 million and $43.1 million, or 12.7% and 12.6% of total operating revenues, for the three months ended September 30, 2013 and 2012, respectively. Operating revenues from properties located in England were $144.0 million and $67.9 million, or 13.1% and 7.3% of total operating revenues, for the nine months ended September 30, 2013 and 2012, respectively. No other foreign country comprised more than 10% of total operating revenues for each of these periods. We had long-lived assets located in England of $1.7 billion and $1.7 billion, or 21.2% and 22.3% of total long-lived assets, as of September 30, 2013 and December 31, 2012, respectively. No other foreign country comprised more than 10% of total long-lived assets as of September 30, 2013 and December 31, 2012.

(m) Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (ASU 2013-02). The amendments in this update require an entity to provide information about the amounts reclassified from accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the income statement or in the notes, significant amounts reclassified from accumulated other comprehensive income by the net income line item. ASU 2013-02 was effective and adopted by the Company in the first quarter of 2013. ASU 2013-02 has impacted the Company’s disclosures, but otherwise did not impact the Company’s condensed consolidated financial position, results of operations or cash flows.

(n) Leasehold Interest Adjustment

During the three months ended September 30, 2013, a $10.0 million non-cash straight-line rent expense adjustment related to the Company’s leasehold interest at 111 8th Avenue in New York was recorded. In September 2010, the Company executed an extension and modification of this leasehold interest, which had been previously scheduled to expire in June 2014, and extended the expiration of the leasehold for another 10 years to June 2024. The Company determined that it should have adjusted the straight-line rent expense recorded on this leasehold interest when the modification was executed in September 2010. The $10.0 million adjustment recorded during the third quarter of 2013 represents a catch-up of the non-cash straight-line rent expense that should have been recorded from the fourth quarter of 2010 through the third quarter of 2013 at a run-rate of approximately $830,000 per quarter. The cumulative effect of the adjustment was deemed to be immaterial to the consolidated financial statements in the current period and the effect in the prior periods was deemed to be immaterial to the prior years impacted.

4. Unconsolidated Joint Venture

On September 27, 2013, we formed a joint venture with an investment fund managed by Prudential Real Estate Investors (PREI^®). We contributed nine Powered Base Building^® data centers valued at approximately $366.4 million plus 20% of $2.8 million of closing costs. The PREI^®-managed fund contributed cash equal to their 80% interest in the joint venture assets at fair value and we retained a 20% interest. The joint venture is structured to provide a current annual preferred return from cash flow first to the PREI^®-managed interest, then to our interest, after which a portion of any excess cash flows is shared by the partners based on their respective interests and the remaining portion is paid to us as a promote interest. We will perform the day-to-day accounting and property management functions for the joint venture and, as such, will earn a management fee. Although we are the managing member of the joint venture and manage the day-to-day activities, all significant decisions, including approval of annual budgets, require approval of the PREI-managed member. Thus, we concluded we do not own a controlling interest and will account for our interest in the joint venture as an equity method investment.

The joint venture has arranged a $185.0 million five-year unsecured bank loan at LIBOR plus 180 basis points, representing a loan-to-value ratio of approximately 50%. Proceeds from the debt offset the contribution amounts required of the partners. The transaction generated approximately $328.6 million of net proceeds to us, comprised of our share of the initial draw-down on the bank loan in addition to the PREI^® fund’s equity contribution, less our share of closing costs and accordingly we recognized a gain of approximately $115.1 million on the sale of the 80% interest in the nine properties during the three months ended September 30, 2013.

The operations of properties that we contributed to the joint venture are not recorded as discontinued operations because of our continuing involvement with these investment properties. Differences between the Company’s investment in the joint venture and the amount of the underlying equity in net assets of the joint venture are due to basis differences resulting from the Company’s equity investment recorded at its historical basis versus the fair value of certain of the Company’s contributions to the joint venture. Our proportionate share of the earnings or losses related to this unconsolidated joint venture is reflected as equity in earnings of unconsolidated joint ventures on the accompanying condensed consolidated income statements.

Global Revolving Credit Facility

On August 15, 2013, the Operating Partnership refinanced its revolving credit facility, which we refer to as the global revolving credit facility, increasing its total borrowing capacity to $2.0 billion from $1.8 billion. The global revolving credit facility has an accordion feature that would enable us to increase the borrowing capacity of the credit facility to $2.55 billion, subject to the receipt of lender commitments and other conditions precedent. The refinanced facility matures on November 3, 2017, with two six-month extension options. The interest rate for borrowings under the expanded facility equals the applicable index plus a margin which is based on the credit rating of our long-term debt and is currently 110 basis points. An annual facility fee on the total commitment amount of the facility, based on the credit rating of our long-term debt and 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, Swiss franc and Japanese yen denominations. As of September 30, 2013, borrowings under the global revolving credit facility bore interest at a blended rate of 1.66% comprised of 1.36% (U.S. dollars), 1.60% (British pound sterling), 1.23% (Euros), 3.66% (Australian dollars), 1.31% (Hong Kong dollars), 1.22% (Japanese yen) and 2.32% (Canadian dollars). The interest rates are based on 1-month LIBOR, 1-month GBP LIBOR, 1-month EURIBOR, 1-month BBR, 1-month HIBOR, 1-month JPY LIBOR and 1-month CAD LIBOR, respectively, plus a margin of 1.10%. We have used and intend to use available borrowings under the global revolving credit facility to acquire additional properties, fund development opportunities and to provide for working capital and other corporate purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or preferred equity securities. As of September 30, 2013, we have capitalized approximately $17.6 million of financing costs related to the global revolving credit facility. As of September 30, 2013, approximately $498.1 million was drawn under this facility and $20.3 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, 2013, we were in compliance with all of such covenants.

Unsecured Term Loan

On August 15, 2013, we refinanced the senior unsecured multi-currency term loan facility, increasing its total borrowing capacity to $1.0 billion from $750.0 million, and pursuant to the accordion feature total commitments can be increased up to $1.1 billion, subject to the receipt of lender commitments and other conditions precedent. The facility matures on April 16, 2017, with two six-month extension options. Interest rates are based on our senior unsecured debt ratings and are currently 120 basis points over the applicable index for floating rate advances. Funds may be drawn in U.S, Singapore and Australian dollars, as well as Euro and British pound sterling denominations with the option to add Hong Kong dollars and Japanese yen upon an accordion exercise. Based on exchange rates in effect at September 30, 2013, the balance outstanding is approximately $950.2 million. We have used borrowings under the term loan for acquisitions, repayment of indebtedness, development, working capital and general corporate purposes. The covenants under this loan are consistent with our global revolving credit facility and, as of September 30, 2013, we were in compliance with all of such covenants. As of September 30, 2013, we have capitalized approximately $8.4 million of financing costs related to the unsecured term loan.

10. Income Taxes

Digital Realty Trust, Inc. (the Parent Company) has elected to be taxed as a REIT and believes that it has complied with the REIT requirements of the Code. As a REIT, the Parent Company is generally not subject to corporate level federal income taxes on taxable income to the extent it is currently distributed to its stockholders. Since inception, the Parent Company has distributed at least 100% of its taxable income annually and intends to do so for the tax year ending December 31, 2013. As such, no provision for federal income taxes has been included in the accompanying condensed consolidated financial statements for the three and nine months ended September 30, 2013 and 2012.

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 and 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, 2013 and 2012.

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 income. 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, 2013 and 2012. As of September 30, 2013, we had a net deferred tax liability of approximately $144.8 million primarily related to our foreign properties, comprised of a $87.8 million deferred tax asset, net of a $232.6 million deferred tax liability. The majority of our net deferred tax liability relates to differences between the tax basis and book basis of the assets acquired in the Sentrum Portfolio acquisition during 2012. In July 2013, we made certain immaterial measurement period adjustments to the provisional amounts initially recorded for the net deferred tax liability recorded as part of the Sentrum acquisition, which closed in July 2012.

11. Equity and Accumulated Other Comprehensive Loss, Net

(a) Equity Distribution Agreements

On June 29, 2011, Digital Realty Trust, Inc. entered into new equity distribution agreements, 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 will be made in “at the market” offerings as defined in Rule 415 of the Securities Act. For the nine months ended September 30, 2012, Digital Realty Trust, Inc. generated net proceeds of approximately $62.7 million from the issuance of approximately 1.0 million common shares under the 2011 Equity Distribution Agreements at an average price of $66.19 per share after payment of approximately $0.6 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, 2013. As of September 30, 2013, shares of common stock having an aggregate offering price of $53.8 million remained available for offer and sale under the program.

(b) Redeemable Preferred Stock

On April 9, 2013, Digital Realty Trust, Inc. issued an aggregate of 10,000,000 shares of its 5.875% series G cumulative redeemable preferred stock, or the series G preferred stock, for gross proceeds of $250.0 million. Dividends are cumulative on the series G preferred stock from the date of original issuance in the amount of $1.46875 per share each year, which is equivalent to 5.875% of the $25.00 liquidation preference per share. Dividends on the series G preferred stock are payable quarterly in arrears. The first dividend paid on the series G preferred stock on June 28, 2013 was a pro rata dividend from and including the original issue date to and including September 30, 2013 in the amount of $0.334550 per share. The series G preferred stock does not have a stated maturity date and is not subject to any sinking fund or mandatory redemption provisions. Upon liquidation, dissolution or winding up, the series G preferred stock will rank senior to Digital Realty Trust, Inc. common stock and rank on parity with Digital Realty Trust, Inc.’s series E

cumulative redeemable and series F cumulative redeemable preferred stock with respect to the payment of distributions and other amounts. Digital Realty Trust, Inc. is not allowed to redeem the series G preferred stock before April 9, 2018, except in limited circumstances to preserve its status as a REIT. On or after April 9, 2018, Digital Realty Trust, Inc. may, at its option, redeem the series G preferred stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends on such series G preferred stock up to but excluding the redemption date. Holders of the series G preferred stock generally have no voting rights except for limited voting rights if Digital Realty Trust, Inc. fails to pay dividends for six or more quarterly periods (whether or not consecutive) and in certain other circumstances. Upon the occurrence of specified changes of control, as a result of which neither Digital Realty Trust, Inc.’s common stock nor the common securities of the acquiring or surviving entity (or American Depositary Receipts representing such securities) is listed on the New York Stock Exchange, or NYSE, the NYSE MKT, LLC, or NYSE MKT, or the NASDAQ Stock Market or listed or quoted on a successor exchange or quotation system, each holder of series G preferred stock will have the right (unless, prior to the change of control conversion date specified in the Articles Supplementary governing the series G preferred stock, Digital Realty Trust, Inc. has provided or provides notice of its election to redeem the series G preferred stock) to convert some or all of the series G preferred stock held by it into a number of shares of Digital Realty Trust, Inc.’s common stock per share of series G preferred stock to be converted equal to the lesser of:

•

the quotient obtained by dividing (i) the sum of the $25.00 liquidation preference plus the amount of any accrued and unpaid dividends to, but not including, the change of control conversion date (unless the change of control conversion date is after a record date for a series G preferred stock dividend payment and prior to the corresponding series G preferred stock dividend payment date, in which case no additional amount for such accrued and unpaid dividend will be included in this sum) by (ii) the common stock price specified in the Articles Supplementary governing the series G preferred stock; and

•

0.7532, or the share cap, subject to certain adjustments;

subject, in each case, to provisions for the receipt of alternative consideration as described in the Articles Supplementary governing the series G preferred stock. Except in connection with specified change of control transactions, the series G preferred stock is not convertible into or exchangeable for any other property or securities of Digital Realty Trust, Inc.

(c) 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 interest in the Operating Partnership as of September 30, 2013 and December 31, 2012:


	September 30, 2013					December 31, 2012
	Number of units		Percentage of total			Number of units		Percentage of total
Digital Realty Trust, Inc.		128,438,970		97.7	%		125,140,783		97.8	%
Noncontrolling interests consist of:
Common units held by third parties		1,500,814		1.2			1,515,814		1.2
Incentive units held by employees and directors (see note 13)		1,481,217		1.1			1,335,586		1.0

		131,421,001		100.0	%		127,992,183		100.0	%

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 and incentive Operating Partnership units met the criteria to be classified within equity.

(1)	This redemption was recorded as a reduction to noncontrolling interests in the Operating Partnership and an increase to common stock and additional paid in capital based on the book value per unit in the accompanying condensed consolidated balance sheet of Digital Realty Trust, Inc.

Under the terms of certain third parties’ (the eXchange parties) contribution agreements signed in the third quarter of 2004, we agreed to indemnify each eXchange party against adverse tax consequences in the event the Operating Partnership directly or indirectly sold, exchanged or otherwise disposed of (whether by way of merger, sale of assets or otherwise) in a taxable transaction any interest in 200 Paul Avenue 1-4 or 1100 Space Park Drive until the earlier of November 3, 2013 or the date on which these contributors or certain transferees hold less than 25% of the Operating Partnership common units issued to them in the formation transactions consummated concurrently with the IPO. Under the eXchange parties’ amended contribution agreement, the Operating Partnership agreed to make approximately $17.8 million of indebtedness available for guaranty by the eXchange parties until the earlier of November 3, 2013 and the date on which these contributors or certain transferees hold less than 25% of the Operating Partnership common units issued to them in the formation transactions consummated concurrently with the IPO, and we agreed to indemnify each eXchange party against adverse tax consequences if the Operating Partnership does not provide such indebtedness to guarantee.

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 on an annual basis, however, in the future we may also need to utilize borrowings under the global revolving credit facility to fund all distributions.

12. Capital and Accumulated Other Comprehensive Loss

(a) Redeemable Preferred Units

On April 9, 2013, the Operating Partnership issued a total of 10,000,000 of its 5.875% series G cumulative redeemable preferred units, or series G preferred units, to Digital Realty Trust, Inc. (the General Partner) in conjunction with the General Partner’s issuance of an equivalent number of shares of its 5.875% series G cumulative redeemable preferred stock, or the series G preferred stock. Distributions are cumulative on the series G preferred units from the date of original issuance in the amount of $1.46875 per unit each year, which is equivalent to 5.875% of the $25.00 liquidation preference per unit. Distributions on the series G preferred units are payable quarterly in arrears. The first distribution paid on the series G preferred units on June 28, 2013 was a pro rata distribution from and including the original issue date to and including June 30, 2013 in the amount of $0.334550 per unit. The series G preferred units do not have a stated maturity date and are not subject to any sinking fund. The Operating Partnership is required to redeem the series G preferred units in the event that the General Partner redeems the series G preferred stock. The General Partner is not allowed to redeem the series G preferred stock prior to April 9, 2018 except in limited circumstances to preserve the General Partner’s status as a REIT. On or after April 9, 2018, the General Partner may, at its option, redeem the series G preferred stock, in whole or in part, at any time or from time to time, for cash at a redemption price of $25.00 per share, plus all accrued and unpaid dividends on such series G preferred stock up to but excluding the redemption date. Upon liquidation, dissolution or winding up, the series G preferred units will rank senior to the Operating Partnership’s common units with respect to the payment of distributions and other amounts and rank on parity with the Operating Partnership’s series E cumulative redeemable preferred units and series F cumulative redeemable preferred units. Except in connection with specified change of control transactions of the General Partner, the series G preferred units are not convertible into or exchangeable for any other property or securities of the Operating Partnership.

(b) 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 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.

(c) Partnership Units

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 the General Partner’s common stock at the time of redemption. Alternatively, the General Partner may elect to acquire those common units in exchange for shares of the General Partner’s 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, the Operating Partnership 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 limited partners’ common units and the vested incentive units. Based on the results of this analysis, the Operating Partnership concluded that the common and vested incentive Operating Partnership units met the criteria to be classified within capital.

The redemption value of the limited partners’ common units and the vested incentive units was approximately $134.9 million and $161.5 million based on the closing market price of Digital Realty Trust, Inc.’s common stock on September 30, 2013 and December 31, 2012, respectively.

13. Incentive Plan

Our Amended and Restated 2004 Incentive Award Plan (as defined below) provides for the grant of incentive awards to employees, directors and consultants. Awards issuable under the Amended and Restated 2004 Incentive Award Plan include stock options, restricted stock, dividend equivalents, stock appreciation rights, long-term incentive units, cash performance bonuses and other incentive awards. Only employees are eligible to receive incentive stock options under the Amended and Restated 2004 Incentive Award Plan. Initially, we had reserved a total of 4,474,102 shares of common stock for issuance pursuant to the 2004 Incentive Award Plan, subject to certain adjustments set forth in the 2004 Incentive Award Plan. On May 2, 2007, Digital Realty Trust, Inc.’s stockholders approved the First Amended and Restated Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2004 Incentive Award Plan (as amended, the Amended and Restated 2004 Incentive Award Plan). The Amended and Restated 2004 Incentive Award Plan increases the aggregate number of shares of stock which may be issued or transferred under the plan by 5,000,000 shares to a total of 9,474,102 shares, and provides that the maximum number of shares of stock with respect to awards granted to any one participant during a calendar year will be 1,500,000 and the maximum amount that may be paid in cash during any calendar year with respect to any performance-based award not denominated in stock or otherwise for which the foregoing limitation would not be an effective limitation for purposes of Section 162(m) of the Code will be $10.0 million.

As of September 30, 2013, 3,210,610 shares of common stock or awards convertible into or exchangeable for common stock remained available for future issuance under the Amended and Restated 2004 Incentive Award Plan. Each long-term incentive unit and Class C Unit issued under the Amended and Restated 2004 Incentive Award Plan will count as one share of common stock for purposes of calculating the limit on shares that may be issued under the Amended and Restated 2004 Incentive Award Plan and the individual award limit discussed above.

(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, whether vested or not, will receive the same quarterly per unit distributions as Operating Partnership common units, which equal 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 of common units of the Operating Partnership, including redemption rights.

In order to achieve full parity with common units, long-term incentive units must be fully vested and the holder’s capital account balance in respect of such long-term incentive units must be equal to the capital account balance of a holder of an equivalent number of common units. The capital account balance attributable to each common unit is generally expected to be the same, in part because of the amount credited to a partner’s capital account upon the partner’s contribution of property to the Operating Partnership, and in part because the partnership agreement provides, in most cases, that allocations of income, gain, loss and deduction (which will adjust the partner’s capital accounts) are to be made to the common units on a proportionate basis. As a result, with respect to a number of long-term incentive units, it is possible to determine the capital account balance of an equivalent number of common units by multiplying the number of long-term incentive units by the capital account balance with respect to a common unit.

A partner’s initial capital account balance is equal to the amount the partner paid (or contributed to the Operating Partnership) for the partner’s units and is subject to subsequent adjustments, including with respect to the partner’s share of income, gain or loss of the Operating Partnership. Because a holder of long-term incentive units generally will not pay for the long-term incentive units, the initial capital account balance attributable to such long-term incentive units will be zero. However, the Operating Partnership is required to allocate income, gain, loss and deduction to the partner’s capital accounts in accordance with the terms of the partnership agreement, subject to applicable Treasury Regulations. The partnership agreement provides that holders of long-term incentive units will receive special allocations of gain in the event of a sale or “hypothetical sale” of assets of the Operating Partnership prior to the allocation of gain to Digital Realty Trust, Inc. or other limited partners with respect to their common units. The amount of such allocation will, to the extent of any such gain, be equal to the difference between the capital account balance of a holder of long-term incentive units attributable to such units and the capital account balance attributable to an equivalent number of common units. If and when such gain allocation is fully made, a holder of long-term incentive units will have achieved full parity with holders of common units. To the extent that, upon an actual sale or a “hypothetical sale” of the Operating Partnership’s assets as described above, there is not sufficient gain to allocate to a holder’s capital account with respect to long-term incentive units, or if such sale or “hypothetical sale” does not occur, such units will not achieve parity with common units.

The term “hypothetical sale” refers to circumstances that are not actual sales of the Operating Partnership’s assets but that require certain adjustments to the value of the Operating Partnership’s assets and the partners’ capital account balances. Specifically, the partnership agreement provides that, from time to time, in accordance with applicable Treasury Regulations, the Operating Partnership will adjust the value of its assets to equal their respective fair market values, and adjust the partners’ capital accounts, in accordance with the terms of the partnership agreement, as if the Operating Partnership sold its assets for an amount equal to their value. Times for making such adjustments generally include the liquidation of the Operating Partnership, the acquisition of an additional interest in the Operating Partnership by a new or existing partner in exchange for more than a de minimis capital contribution, the distribution by the Operating Partnership to a partner of more than a de minimis amount of partnership property as consideration for an interest in the Operating Partnership, in connection with the grant of an interest in the Operating Partnership (other than a de minimis interest) as consideration for the performance of services to or for the benefit of the Operating Partnership (including the grant of a long-term incentive unit), and at such other times as may be desirable or required to comply with the Treasury Regulations.

During the nine months ended September 30, 2013 and 2012, certain employees and directors were granted an aggregate of 89,769 and 79,237 long-term incentive units, respectively. During the nine months ended September 30, 2013 and 2012, certain employees were also granted an aggregate of 95,316 and 86,843 long-term incentive units, respectively, which, in addition to a service condition, are subject to a performance condition that impacts the number of units which ultimately vests. The performance condition is based upon our achievement of the respective fiscal years’ Funds From Operations, or FFO, per share targets. Upon evaluating the results of the performance condition, the final number of units is determined and such units vest based on satisfaction of the service conditions. The service conditions of the awards provide for 20% vesting on each of the first and second anniversaries of the grant date and 30% vesting on each of the third and fourth anniversaries of the grant date, provided the grantee continues employment on each anniversary date. Based on our 2012 FFO per diluted share and unit, 78,118 of the 2012 long-term incentive units, net of forfeitures, satisfied the performance condition. The grant date fair values, which equal the market price of Digital Realty Trust, Inc. common stock, are being expensed on a straight-line basis for service awards over the vesting period of the long-term incentive units, which ranges from three to five years. For performance based awards, we expense the fair value using an accelerated method with each vesting tranche valued as a separate award.

The expense recorded for each of the three months ended September 30, 2013 and 2012 related to long-term incentive units was approximately $2.1 million and approximately $7.2 million for each of the nine months ended September 30, 2013 and 2012. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $0.4 million for each of the three months ended September 30, 2013 and 2012 and approximately $1.3 million and $0.8 million for the nine months ended September 30, 2013 and 2012, respectively. Unearned compensation representing the unvested portion of the long-term incentive units totaled $16.3 million and $13.3 million as of September 30, 2013 and December 31, 2012, respectively. We expect to recognize this unearned compensation over the next 2.7 years on a weighted average basis.

(b) Class C Profits Interest Units

On May 2, 2007, we granted awards of Class C Profits Interest Units of the Operating Partnership or similar stock-based performance awards, which we refer to collectively as the Class C Units, under the Amended and Restated 2004 Incentive Award Plan (2007 Grant) to each of our named executive officers and certain other officers and employees.

The Class C Units subject to this award were subject to vesting based on the achievement of a total stockholder return (which we refer to as the market condition) as measured on November 1, 2008 (which we refer to as the first measurement date) and May 1, 2010 (which we refer to as the second measurement date).

We previously determined that the market condition with respect to the first measurement date was not achieved. On May 1, 2010, we determined that 593,316 of the Class C Units and 20,169 shares of restricted stock subject to the 2007 Grant satisfied the market condition on the second measurement date (May 1, 2010), with the value of these units equal to the maximum amount of the award pool payable pursuant to the 2007 Grant on the second measurement date. Of the Class C Units that satisfied the market condition on May 1, 2010, 60% vested on May 1, 2010 and the remaining 40% vested ratably each month through June 30, 2012.

The fair value of the 2007 Grant was measured on the grant date using a Monte Carlo simulation to estimate the probability of the multiple market conditions being satisfied. The Monte Carlo simulation uses a statistical formula underlying the Black-Scholes and binomial formulas, and such simulation was run approximately 100,000 times. For each simulation, the value of the payoff was calculated at the settlement date and was then discounted to the grant date at a risk-free interest rate. The expected value of the Class C Units on the grant date was determined by multiplying the average of the values over all simulations by the number of outstanding shares of Digital Realty Trust, Inc. common stock and Operating Partnership units. The valuation was performed in a risk-neutral framework, so no assumption was made with respect to an equity risk premium. Other significant assumptions used in the valuation included an expected term of 36 months, expected stock price volatility of 23%, a risk-free interest rate of 4.6%, and a dividend growth rate of 5.0%. The fixed award limit under the plan was $17 million for the first market condition and $40 million for the second market condition, and there were 69.2 million shares of Digital Realty Trust, Inc. common stock and Operating Partnership units outstanding as of the 2007 grant date. The grant date fair value of these awards of approximately $11.8 million was recognized as compensation expense on a straight-line basis over the expected service period of five years, which ended during the three months ended June 30, 2012.

(d) Restricted Stock

During the nine months ended September 30, 2013 and 2012, certain employees were granted an aggregate of 69,423 and 45,184 shares of restricted stock, respectively. During the nine months ended September 30, 2013 and 2012, certain employees were also granted an aggregate of 69,995 and 52,947 shares of restricted stock, respectively, which, in addition to a service condition, are subject to a performance condition that impacts the number of shares which ultimately vests. The performance condition is based upon our achievement of the respective year’s FFO per share targets. Upon evaluating the results of the performance condition, the final number of shares is determined and such shares vest based on satisfaction of the service conditions. The service conditions of the awards provide for 20% vesting on each of the first and second anniversaries of the grant date and 30% vesting on each of the third and fourth anniversaries of the grant date provided the grantee continues employment on each anniversary date. Based on our 2012 FFO per diluted share and unit, 49,325 of the 2012 restricted stock, net of forfeitures, satisfied the performance condition.

The grant date fair values, which equal the market price of Digital Realty Trust, Inc. common stock, are being expensed on a straight-line basis for service awards over the vesting period of the restricted stock, which ranges from three to four years. For performance based awards, we expense the fair value using an accelerated method with each vesting tranche valued as a separate award.

The expense recorded for the three months ended September 30, 2013 and 2012 related to grants of restricted stock was approximately $0.8 million and approximately $0.6 million, respectively, and approximately $2.2 million and approximately $2.1 million for the nine months ended September 30, 2013 and 2012, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $0.7 million and $0.6 million for the three months ended September 30, 2013 and 2012, respectively, and approximately $1.9 million and $1.5 million for the nine months ended September 30, 2013 and 2012, respectively. Unearned compensation representing the unvested portion of the restricted stock totaled $10.9 million and $7.4 million as of September 30, 2013 and December 31, 2012, respectively. We expect to recognize this unearned compensation over the next 2.9 years on a weighted average basis.

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 December 31, 2012, 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, 2013 or December 31, 2012.

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 US LIBOR, GBP LIBOR and EURIBOR based mortgage loans as well as the U.S. LIBOR and SGD-SOR based tranches of the unsecured term loan. 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 current and pervasive disruptions in the financial markets have heightened the risks to these institutions.

Our agreements with some of our derivative counterparties provide that (1) we could be declared in default on our derivative obligations if repayment of any of our indebtedness over $75.0 million is accelerated by the lender due to our default on the indebtedness and (2) we could be declared in default on a certain derivative obligation if we default on any of our indebtedness, including a default where repayment of underlying indebtedness has not been accelerated by the lender.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the three and nine months ended September 30, 2013 and 2012, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. The fair value of these derivatives was ($0.6) million and ($8.7) million at September 30, 2013 and December 31, 2012, respectively. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the three and nine months ended September 30, 2013 and 2012, there were no ineffective portions to our interest rate swaps.

Amounts reported in accumulated other comprehensive loss related to interest rate swaps will be reclassified to interest expense as interest payments are made on our debt. As of September 30, 2013, we estimate that an additional $3.3 million will be reclassified as an increase to interest expense during the twelve months ending September 30, 2014, as the hedged forecasted transactions impact earnings.

As of September 30, 2013 and December 31, 2012, we had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk (in thousands):

15. Fair Value of Instruments

We disclose fair value information about all financial instruments, whether or not recognized in the condensed consolidated balance sheets, for which it is practicable to estimate fair value. Current accounting guidance requires the 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, 2013 and December 31, 2012 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, the interest rate swaps are recorded at fair value.

We calculate the fair value of our mortgage loans, unsecured term loan, unsecured senior notes and exchangeable senior debentures 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 debt. The carrying value of our global revolving credit facility approximates fair value, due to the variability of interest rates.

As of September 30, 2013 and December 31, 2012, the aggregate estimated fair value and carrying value of our global revolving credit facility, unsecured term loan, unsecured senior notes, exchangeable senior debentures and mortgage loans were as follows (in thousands):


	Categorization under the fair value hierarchy		As of September 30, 2013				As of December 31, 2012

16. Related Party Transactions

In December 2006, we entered into ten leases with tel(x) pursuant to which tel(x) provides enhanced meet-me-room services to our customers. The initial terms of these leases expire in 2026, and tel(x) has options to extend them through 2046. tel(x) was acquired by GI Partners Fund II, LLP in November 2006, which, collectively with GI Partners Side Fund II, L.P., owned the majority of the outstanding stock of tel(x). Richard Magnuson, our former director and Chairman who served until our 2012 Annual Meeting of Stockholders, or the 2012 Annual Meeting, is the chief executive officer of the advisor to GI Partners Fund II, LLP and GI Partners Side Fund II, L.P. During the year ended December 31, 2011, GI Partners Fund II, LLP and GI Partners Side Fund II, L.P completed the sale of tel(x) to an unrelated third party. Our condensed consolidated income statements include rental revenues of approximately $15.6 million and $12.0 million from tel(x) for the three months ended September 30, 2013 and 2012, respectively, and approximately $44.0 million and $33.7 million for the nine months ended September 30, 2013 and 2012, respectively. In connection with the lease agreements, we entered into an operating agreement with tel(x), effective as of December 1, 2006, with respect to joint sales and marketing efforts, designation of representatives to manage the national relationship between us and tel(x) and future meet-me-room facilities. As of September 30, 2013 and December 31, 2012, tel(x) leased from us 331,002 square feet under 51 lease agreements and 288,940 square feet under 44 lease agreements, respectively; all but ten leases for 76,684 square feet were entered into prior to the sale of tel(x) to an unrelated third party in September 2011.

We also entered into an agreement with tel(x), effective as of December 1, 2006, with respect to percentage rent arising out of potential future lease agreements for rentable space in buildings covered by the meet-me-room lease agreements. Percentage rent earned during the three months ended September 30, 2013 and 2012 amounted to approximately $2.0 million and $1.7 million, respectively, and approximately $3.9 million and $3.1 million during the nine months ended September 30, 2013 and 2012, respectively. In addition, in connection with the lease agreements, we entered into a management agreement with tel(x), effective as of December 1, 2007, pursuant to which tel(x) agreed to provide us with certain management services in exchange for a management fee of one percent of rents actually collected by tel(x).

We are party to nine leases with SoftLayer, all of which are in place as of September 30, 2013. The initial terms of these leases expire from 2013 to 2025, and SoftLayer has options to extend them from 2018 through 2035. On August 3, 2010, GI Partners Fund III, L.P. acquired a controlling interest in SoftLayer. Richard Magnuson, our former director and Chairman who served until our 2012 Annual Meeting, is also a manager of the general partner to GI Partners Fund III, L.P. Our condensed consolidated income statements include rental revenues of approximately $14.9 million and $19.4 million from SoftLayer for the three months ended September 30, 2013 and 2012, respectively, and approximately $40.6 million and $41.2 million for the nine months ended September 30, 2013 and 2012, respectively. In July 2013, SoftLayer was acquired by IBM.

Mr. Magnuson did not stand for re-election to our Board of Directors at our 2012 Annual Meeting. His term as a member of our Board of Directors and our Chairman ended effective April 23, 2012, the date of the 2012 Annual Meeting.

17. Commitments and Contingencies

(a) Contingent liabilities

As part of the acquisition of 29A International Business Park, the seller could earn additional consideration based on future net operating income growth in excess of certain performance targets, as defined. As of September 30, 2013, construction is not complete and none of the leases executed subsequent to purchase would cause an amount to become probable of payment and therefore no amount is accrued as of September 30, 2013. The maximum amount that could be earned by the seller is $50.0 million SGD (or approximately $39.8 million based on the exchange rate as of September 30, 2013). The earnout contingency expires in November 2020.

One of the tenants at our Convergence Business Park property has an option to expand as part of their lease agreement, which expires in April 2017. As part of this option, development activities are not permitted on specifically identified expansion space within the property until April 2014. If the tenant elects to take this option, we can elect one of two options. The first option is to construct and develop an additional shell building on the expansion space. Concurrent with this obligation, the tenant would execute an amendment to the existing lease to reflect the expansion of the space and include the additional shell building. The second option is to sell the existing building and the expansion space to the tenant for a price of approximately $24.0 million and $225,000 per square acre, respectively, plus additional adjustments as provided in the lease.

As part of the acquisition of the Sentrum Portfolio, the seller could earn additional consideration based on future net returns on vacant space to be developed, but not currently leased, as defined in the purchase agreement for the acquisition. The initial estimate of fair value of contingent consideration was approximately £56.5 million (or approximately $87.6 million based on the exchange rate as of July 11, 2012, the acquisition date). During the three months ended March 31, 2013, we made certain immaterial corrections to the initial measurement of the accrued contingent consideration that resulted in an additional $5.8 million of purchase price allocated to investments in real estate. These corrections had no impact on reported net income for the period. We have adjusted the contingent consideration to fair value at each reporting date with changes in fair value recognized in operating income. At September 30, 2013, the fair value of the contingent consideration for Sentrum was £45.2 million (or approximately $73.1 million based on the exchange rate as of September 30, 2013) and is currently accrued in accounts payable and other accrued expenses in the condensed consolidated balance sheet. During the nine months ended September 30, 2013, we have made earnout payments of approximately £16.9 million (or approximately $25.8 million based on the exchange rates as of the date of each payment). Change in fair value of contingent consideration for Sentrum was an increase to operating income of approximately $0.9 million and $13.0 thousand for the three and nine months ended September 30, 2013, respectively. The earn-out contingency expires in July 2015. This amount will be reassessed on a quarterly basis, with any changes being recognized in earnings. Increases or decreases in the fair value of the contingent consideration can result from changes in discount periods, discount rates and probabilities that contingencies will be met.

(b) Construction Commitments

Our properties require periodic investments of capital for tenant-related capital expenditures and for general capital improvements and from time to time in the normal course of our business, we enter into various construction contracts with third parties that may obligate us to make payments. At September 30, 2013, we had open commitments related to construction contracts of approximately $191.7 million.

(c) Legal Proceedings

Although the Company is involved in legal proceedings arising in the ordinary course of business, as of September 30, 2013, the Company is not currently a party to any legal proceedings, nor, to its knowledge, is any legal proceeding threatened against it that it believes would have a material adverse effect on its financial position, results of operations or liquidity.

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 our capital resources, expected use of proceeds from our equity distribution program and other securities offerings, expected use of borrowings under our credit facility, portfolio performance, leverage policy, acquisition and capital expenditure plans, supply and demand for data center space, capitalization rates 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 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: the impact of the recent deterioration in global economic, credit and market conditions, including the downgrade of the U.S. government’s credit rating; current local economic conditions in our geographic markets; decreases in information technology spending, including as a result of economic slowdowns or recession; 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); our dependence upon significant tenants; bankruptcy or insolvency of a major tenant or a significant number of smaller tenants; defaults on or non-renewal of leases by tenants; our failure to obtain necessary debt and equity financing; increased interest rates and operating costs; 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; financial market fluctuations; changes in foreign currency exchange rates; our inability to manage our growth effectively; difficulty acquiring or operating properties in foreign jurisdictions; the suitability of our properties and data center infrastructure, delays or disruptions in connectivity, failure of our physical infrastructure or services or availability of power; our failure to successfully integrate and operate acquired or developed properties or businesses; risks related to joint venture investments, including as a result of our lack of control of such investments; delays or unexpected costs in development of properties; decreased rental rates or increased vacancy rates; increased competition or available supply of data center space; our inability to successfully develop and lease new properties and space held for development; difficulties in identifying properties to acquire and completing acquisitions; our inability to acquire off-market properties; our inability to comply with the rules and regulations applicable to reporting companies; Digital Realty Trust, Inc.’s failure to maintain its status as a REIT for federal income tax purposes; possible adverse changes to tax laws; restrictions on our ability to engage in certain business activities; environmental uncertainties and risks related to natural disasters; losses in excess of our insurance coverage; changes in foreign laws and regulations, including those related to taxation and real estate ownership and operation; and changes in local, state and federal regulatory requirements, including changes in real estate and zoning laws and increases in real property tax rates.

While forward-looking statements reflect our good faith beliefs, they are not guaranties 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 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.

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 and (ii) cash flow and returns to our stockholders and our operating partnership’s unitholders through the payment of distributions. We expect to achieve our objectives by focusing on our core business of investing in and developing technology-related real estate. A significant component of our current and future internal growth is anticipated through the development of our existing space held for development and new properties. We target high quality, strategically located properties containing applications and operations critical to the day-to-day operations of corporate enterprise datacenter and technology industry tenants and properties that may be developed for such use. Most of our properties contain fully redundant electrical supply systems, multiple power feeds, above-standard precision cooling systems, raised floor areas, extensive in-building communications cabling and high-level security systems. We focus solely on technology-related real estate because we believe that the growth in corporate datacenter adoption and the technology-related real estate industry generally will continue to be superior to that of the overall economy.

As of September 30, 2013, we owned an aggregate of 130 technology-related real estate properties, including 12 properties held as investments in unconsolidated joint ventures, with approximately 24.0 million rentable square feet including approximately 2.8 million square feet of space held for development. The 12 properties held as investments in unconsolidated joint ventures have an aggregate of approximately 1,512,000 rentable square feet. In addition, we own 11 parcels of developable land comprised of approximately 158 acres. At September 30, 2013, approximately 1,533,000 square feet was under construction for Turn-Key Flex^SM, Powered Base Building^® and Custom Solutions (formerly referred to as Build-to-Suit) products, all of which are expected to be income producing on or after completion, in 10 U.S. domestic markets, two European markets, one Canadian market and one Australian market, consisting of approximately 691,000 square feet of space under development projects and 842,000 square feet of land under development projects.

We have developed detailed, standardized procedures for evaluating acquisitions to ensure that they meet our financial, technical and other criteria. We expect to continue to acquire additional assets as a part of our growth strategy. We intend to aggressively manage and lease our assets to increase their cash flow. We intend to continue to build out our development portfolio when justified by anticipated 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 currently intend to limit our indebtedness to 60% of our total enterprise value and, based on the closing price of Digital Realty Trust, Inc. common stock on September 30, 2013 of $53.10, our ratio of debt to total enterprise value was approximately 38%. 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), excluding options issued under our company’s incentive award plan, 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. common stock and excluding long-term incentive units and Class C units), plus the book value of our total consolidated indebtedness.

Revenue base. As of September 30, 2013, we owned 130 properties through our operating partnership, including 12 properties held as investments in unconsolidated joint ventures and developable land. These properties are mainly located throughout the U.S., with 22 properties located in Europe, three properties in Australia, two properties in Canada and two properties in Asia. We, through our predecessor, acquired our first portfolio property in January 2002 and have added properties as follows:

(1)

Excludes properties sold: 100 Technology Center Drive (March 2007), 4055 Valley View Lane (March 2007) and 7979 East Tufts Avenue (July 2006). Also excludes a leasehold interest acquired in March 2007 related to an acquisition made in 2006. Includes ten properties held in our managed portfolio of unconsolidated joint ventures consisting of 4650 Old Ironsides Drive (Silicon Valley), 2950 Zanker Road (Silicon Valley), 4700 Old Ironsides Drive (Silicon Valley), 444 Toyama Drive (Silicon Valley), 43790 Devin Shafron Drive (Northern Virginia), 21551 Beaumeade Circle (Northern Virginia), 7505 Mason King Court (Northern Virginia), 14901 FAA Boulevard (Dallas), 900 Dorothy Drive (Dallas) and 33 Chun Choi Street (Hong Kong); and two unconsolidated non-managed joint ventures: 2001 Sixth Avenue (Seattle) and 2020 Fifth Avenue (Seattle).

(2)

Current net rentable square feet as of September 30, 2013, 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 tenants’ proportional share of common areas but excludes space held for development.

(3)

Space held for development is unoccupied space that requires significant capital investment in order to develop datacenter facilities that are ready for use. In certain circumstances this may include datacenter space that requires a large capital investment in order to build out the space. The amounts included in this table represent development space as of September 30, 2013 in the properties acquired during the relevant period.

(4)	Includes three developed buildings (43915 Devin Shafron Drive, 43830 Devin Shafron Drive and 43790 Devin Shafron Drive) placed into service in 2010 and 2011 that are being included with a property (Devin Shafron buildings) that was acquired in 2007.

(5)	Includes a developed building (21551 Beaumeade Circle) placed into service in 2011 that is being included with a property (Beaumeade Circle Portfolio) that was acquired in 2009.

(6)	Includes four developed buildings (43940 Digital Loudoun Plaza in Northern Virginia, 3825 NW Aloclek Place in Portland, Oregon, 98 Radnor Drive in Melbourne, Australia and 1-23 Templar Road in Sydney, Australia) placed into service in 2013 and 2012 that were acquired in 2011.

(7)

43790 Devin Shafron Drive and 21551 Beaumeade Circle, which were previously included as part of the Devin Shafron buildings and Beaumeade Portfolio, respectively, are now each separately included in the property count because they were separately contributed to an unconsolidated joint venture in September 2013.

In May 2008, we acquired 701 & 717 Leonard Street, a parking garage in Dallas, Texas; however, we exclude the acquisition from our property count because it is located adjacent to our internet gateway datacenter located at 2323 Bryan Street and is not considered a separate property.

On September 27, 2013, we formed a joint venture with an investment fund managed by Prudential Real Estate Investors (PREI^®). We contributed nine Powered Base Building^® data centers totaling 1.06 million square feet and valued at approximately $366.4 million (excluding $2.8 million of closing costs). The PREI^®-managed fund took an 80% interest in the joint venture and we retained a 20% interest. The joint venture is structured to provide a current annual preferred return from cash flow first to the PREI^®-managed interest, then to our interest, after which a portion of any excess cash flows is shared by the partners based on their respective interests and the remaining portion is paid to us as a promote interest. We will perform the day-to-day accounting and property management functions for the joint venture and, as such, will earn a management fee for the services provided. Although we are the managing member of the joint venture and manage the day-to-day activities, all significant decisions, including approval of annual budgets and setting the amount of our management fees require approval of the PREI^® member. Thus we concluded we do not own a controlling interest and will account for our interest in the joint venture as an equity method investment, which will result in a reduction in same-store revenues and net income from these properties on our income statement relative to historical periods.

As of September 30, 2013, the properties in our portfolio were approximately 92.6% leased excluding 2.8 million square feet of space held for development and 12 properties held as investments in unconsolidated joint ventures. 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, 2013, our original average lease term was approximately 12 years, with an average of approximately seven years remaining. Our lease expirations through December 31, 2014 are 8.5% of rentable square feet, excluding space held for development as of September 30, 2013.

Factors Which May Influence Future Results of Operations

Global market and economic conditions

In the United States and globally, market and economic conditions have been unprecedented over the past few years and challenging with tighter credit conditions and slower economic growth in all markets in which we own properties and conduct our operations. The U.S. and global economies have experienced a recession and face continued concerns about the systemic impact of adverse economic conditions, such as high energy costs, geopolitical issues, the availability and cost of credit, unstable global financial and mortgage markets, high corporate, consumer and governmental debt levels, ongoing sovereign debt and economic issues in European countries, concerns regarding the U.S. budget deficit, debt ceiling, spending cuts and the possibility of further downgrades to the U.S. government’s credit rating, high unemployment and declining residential and commercial real estate markets. The European debt crisis, particularly most recently in Greece, Italy, Ireland, Portugal and Spain, has raised concerns regarding the debt burden of certain countries using the euro as their currency and their ability to meet future financial obligations, the overall stability of the euro and the suitability of the euro as a single currency given the diverse economic and political circumstances in individual eurozone countries. These concerns could lead to the re-introduction of individual currencies in one or more eurozone countries, or, in more extreme circumstances, the possible dissolution of the euro currency entirely. Should the euro be dissolved entirely, the legal and contractual consequences for parties to euro-denominated contracts are uncertain and would be determined by laws in effect at such time. These potential developments, or market perceptions concerning these and related issues, could adversely affect our leasing and financing activities, rents we receive, potential acquisitions and development projects in Europe.

As a result of these conditions, general economic conditions and the cost and availability of capital have been and may again be adversely affected in some or all of the markets in which we own properties and conduct our operations. Renewed or increased turbulence in the U.S., European, Asia Pacific and other international financial markets and economies may adversely affect our ability, and the ability of our tenants, 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 tenants’, financial condition and results of operations.

In addition, our access to funds under our global revolving credit facility and other lines of credit depend 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 properties possibly on disadvantageous terms or entering into or renewing leases on less favorable terms than we otherwise would.

Rental income. The amount of rental income generated by the properties in our portfolio depends on several factors, including our ability to maintain or improve the occupancy rates of currently leased space and to lease currently available space and space available from lease terminations. Excluding 2.8 million square feet of space held for development and 12 properties held as investments in unconsolidated joint ventures, as of September 30, 2013, the occupancy rate of the properties in our portfolio was approximately 92.6% of our net rentable square feet.

As of September 30, 2013, we had 2,103 leases with a total of 639 tenants in our portfolio, including the ten properties held in our managed portfolio of unconsolidated joint ventures. As of September 30, 2013, approximately 85% 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 19.5 million net rentable square feet, excluding space held for development and 12 properties held as investments in unconsolidated joint ventures, at September 30, 2013 is approximately 571,000 square feet of datacenter space with extensive installed tenant improvements available for lease. Since our IPO, we have leased approximately 3,414,000 square feet of similar space, including Turn-Key Flex^SM space. Our Turn-Key Flex^SM product is an effective solution for tenants who prefer to utilize a partner with the expertise or capital budget to provide extensive datacenter infrastructure and security. Our expertise in datacenter construction and operations enables us to lease space to these tenants at a premium over other uses. In addition, as of September 30, 2013, we had approximately 2.8 million square feet of space held for development, or approximately 13% of the total rentable space in our portfolio, including three vacant properties comprising approximately 444,000 square feet and excluding 12 properties 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 datacenter 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 tenant 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 markets or downturns in the technology-related real estate 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 tenants 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 1.5 million square feet of available space in our portfolio, which excludes approximately 2.8 million square feet of space held for development as of September 30, 2013 and 12 properties held as investments in unconsolidated joint ventures, leases representing approximately 1.6% and 6.9% of the net rentable square footage of our portfolio are scheduled to expire during the three months ending December 31, 2013 and the year ending December 31, 2014, respectively.

During the nine months ended September 30, 2013, we signed new leases totaling approximately 846,000 square feet of space and renewal leases totaling approximately 1,127,000 square feet of space. The following table summarizes our leasing activity in the nine months ended September 30, 2013:

(1)	The number of leases represents the leased-unit count; a lease could include multiple units.

(2)	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.

(3)	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.

(4)	Excludes short term leases.

(5)	Commencement dates for the leases signed range from 2013 to 2018.

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 markets for datacenter space and, subject to the supply of available datacenter space in these markets, expect the rental rates we are likely to achieve on any new, re-leased or renewed datacenter space leases for 2013 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 flat on a cash basis. For the nine months ended September 30, 2013, rents on renewed space increased by an average of 2.7% on a GAAP basis on our Turn-Key Flex^SM space compared to the expiring

rents and increased by an average of 38.9% 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 properties 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 market 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 datacenter space, competition from other datacenter developers or operators, the condition of the property and whether the property, or space within the property, has been developed.

Market concentration. We depend on the market for technology-based real estate in specific geographic regions and significant changes in these regional markets can impact our future results. As of September 30, 2013, our portfolio was geographically concentrated in the following metropolitan markets:


Metropolitan Market	Percentage of September 30, 2013 total annualized rent ⁽¹⁾
London, England		12.0	%
Northern Virginia		9.8	%
Dallas		9.3	%
New York Metro		9.1	%
Silicon Valley		8.9	%
Chicago		7.3	%
San Francisco		7.3	%
Phoenix		6.8	%
Boston		4.5	%
Los Angeles		3.8	%
Seattle		3.2	%
Paris, France		2.7	%
Other		15.3	%

		100.0	%

(1)	Annualized rent is monthly contractual rent (defined as cash base rent before abatements) under existing leases as of September 30, 2013 multiplied by 12. The aggregate amount of abatements for the nine months ended September 30, 2013 was approximately $24.5 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 datacenter operations contained in them. Many of our leases contain provisions under which the tenants reimburse us for a portion of property operating expenses and real estate taxes incurred by us. However, we generally are not entitled to reimbursement of property operating expenses, other than utility expense, and real estate taxes under our leases for Turn-Key Flex^SM 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, 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, create new clean energy jobs and enhance the energy independence of the United States, which included a cap-and-trade program for GHG emissions. 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. As a result, action to reduce GHG emissions likely will be focused on regulatory agencies, primarily the U.S. Environmental Protection Agency, or EPA, and state actions. EPA has been moving aggressively to regulate GHG emissions from automobiles and large stationary sources, including electricity producers, using its own authority under the Clean Air Act. EPA made an endangerment finding in 2009 that allows it to create regulations imposing emission 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 known until all regulations are finalized.

EPA has already finalized its GHG “reporting rule,” which requires that certain emitters, including electricity generators, monitor and report GHG emissions. The EPA has also finalized its “tailoring rule,” which imposes 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, NSR PSD or Title V permits issued after January 2, 2011, for new or modified electricity generating and other facilities may need to address GHG emissions, including by requiring the installation of Best Available Control Technology. Some of those regulations have been finalized and currently are in litigation. Courts have rejected certain legal challenges to the endangerment findings, the tailoring rule, and other regulations but other legal challenges are pending. In addition, EPA proposed in April 2012 a rule that would set a GHG emission standard applicable to new electricity generating units, and EPA re-proposed the rule in September. The Obama Administration issued a plan in June 2013 under which EPA is to issue a final rule by 2015 regulating GHG emissions from existing electricity generating units. 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 addition, since 2005 the European Union (including the United Kingdom) has been operating under a cap-and-trade program, which directly affects the largest emitters of GHGs, including electricity producers from whom we purchase power. 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 U.S. EPA has proposed or finalized, (iii) regulations under legislation that states have passed or may pass, or (iv) any further reductions in the EU program could significantly increase our costs, and we may not be able to effectively pass all of these costs on to our tenants.

Interest rates. As of September 30, 2013, we had approximately $639.7 million of variable rate debt subject to interest rate swap agreements, including $77.9 million of mortgage debt and $561.8 million on our unsecured term loan, along with $498.1 million and $388.4 million of variable rate debt that was outstanding on the global revolving credit facility and the unswapped portion of the unsecured term loan, respectively. The availability of debt and equity capital may decrease as a result of the circumstances described above under “Global market and economic conditions.” 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 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 datacenter space. Our portfolio of properties consists primarily of technology-related real estate and datacenter real estate in particular. A decrease in the demand for, or increase in supply of, datacenter 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 tenant base or less specialized use. Over the past two years, we have made a significant investment in building out additional inventory primarily in what we anticipate will be our active major markets prior to having executed leases with respect to this space. We believe that demand continues to exceed supply in most markets in which we operate, particularly in Northern Virginia, Dallas, Amsterdam and London, whereas we anticipate that our Silicon Valley market may be at risk of significant over-supply. However, until this inventory is leased up, which will depend on a number of factors, including available datacenter space in these markets, 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 datacenter, 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 datacenter space. Reduced demand could also result from business relocations, including to markets 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 datacenter 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 tenants’ 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 datacenter space in our properties, or the rates at which we lease space, may be adversely impacted either across our portfolio or in specific markets as a result of an increase in the number of competitors, or the amount of space being offered in our markets and other markets 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 note 2 to our condensed consolidated financial statements included elsewhere in this report. 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 tenants, 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, 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 in place leases is recorded as an 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 condensed consolidated statements of operations.

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 activities, including development of plans, process of obtaining permits from governmental authorities and physical construction that are necessary to get the asset ready for its intended use are in progress and costs have been incurred. 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. We cease cost capitalization if activities necessary for the development of the property have been suspended. Capitalized costs are allocated to the specific components of a project that are benefited.

During the second quarter of 2013, in accordance with U.S. GAAP, we refined our capitalization practice related to operating expenditures which could have been capitalized, but had been expensed. Previously, operating expenditures totaling $10,000 or less that could have been capitalized had been expensed as incurred for efficiency purposes. Under our refined capitalization practice, retrospective to January 1, 2013, such expenses are now capitalized. Additionally, we conformed the construction period completion date, which is when capitalization of construction period operating costs ceases, with our construction period interest capitalization policy. Previously, capitalization of construction period operating costs ceased upon the commissioning date. Retrospective to January 1, 2013, capitalization of construction period operating costs now ceases on receipt of the certificate of occupancy, among other factors. The total incremental amounts capitalized during the second quarter of 2013 that would have been recorded as rental property operating expense under our previous policies was approximately $3.4 million, of which approximately $1.5 million related to the first quarter. This first quarter amount reduced rental property operating expense in the second quarter as reflected in our consolidated income statement included elsewhere in this report. During the three months ended September 30, 2013, the total incremental amounts capitalized that would have been recorded as rental property operating expense under our previous policies was approximately $2.5 million.

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 significant adverse change in the extent or manner in which the property is being used in its physical condition 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. No such impairment losses have been recognized to date.

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.

Revenue Recognition

Rental income is recognized using the straight-line method over the terms of the tenant leases. Deferred rents included in our condensed consolidated balance sheets represent the aggregate excess of rental revenue recognized to date on a straight-line basis versus the contractual rental payments under the terms of the leases. Many of our leases contain provisions under which the tenants reimburse us for a portion of property operating expenses and real estate taxes incurred by us. However, we generally are not entitled to reimbursement of property operating expenses, other than utility expense, and real estate taxes under our leases for Turn-Key Flex^SM facilities. Such reimbursements 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, tenant concentrations, tenant creditworthiness and current economic trends when evaluating the adequacy of the allowance for bad debts. These estimates have a direct impact on our net income because a higher bad debt allowance would result in lower net income, and recognizing rental revenue as earned in one period versus another would result in higher or lower net income for a particular period.

Share-Based Awards

We recognize compensation expense related to share-based awards. We generally amortize this compensation expense over the vesting period of the award. The calculation of the fair value of share-based awards is subjective and requires several assumptions over such items as expected stock volatility, dividend payments and future company results. These assumptions have a direct impact on our net income because a higher share-based awards amount would result in lower net income for a particular period.

Results of Operations

The discussion below relates to our financial condition and results of operations for the three and nine months ended September 30, 2013 and 2012. A summary of our operating results for the three and nine months ended September 30, 2013 and 2012 is as follows (in thousands).

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 resulting both from the new property additions to our portfolio, as well as on a “same store” property basis (new properties are properties that were acquired after December 31, 2011 along with the nine properties that were contributed to our joint venture with the PREI^®-managed fund in September 2013). The following table identifies each of the properties in our portfolio acquired from January 1, 2012 through September 30, 2013.

(1)	Space held for development is unoccupied space that requires significant capital investment in order to develop datacenter facilities that are ready for use. In certain circumstances this may include datacenter space that requires a large capital investment in order to build out the space.

(2)

Net rentable square feet at a building represents the current square feet at that building under lease as specified in the lease agreements plus management’s estimate of space available for lease based on engineering drawings. Net rentable square feet includes tenants’ proportional share of common areas but excludes space held for development.

(3)	Occupancy rates exclude space held for development. For some of our properties, we calculate occupancy based on factors in addition to contractually leased square feet, including available power, required support space and common area.

Comparison of the Three Months Ended September 30, 2013 to the Three Months Ended September 30, 2012 and the Nine Months Ended September 30, 2013 to the Nine Months Ended September 30, 2012

Portfolio

As of September 30, 2013, our portfolio consisted of 130 properties, including 12 properties held as investments in unconsolidated joint ventures and developable land, with an aggregate of 24.0 million rentable square feet, including 2.8 million square feet of space held for development, compared to a portfolio consisting of 115 properties, including three properties held as investments in unconsolidated joint ventures and developable land, with an aggregate of 21.6 million rentable square feet, including 2.2 million square feet of space held for development as of September 30, 2012. We acquired 11 properties and developed four properties (land was acquired prior to September 30, 2012) during the twelve months ended September 30, 2013. On September 27, 2013, we contributed nine properties to an unconsolidated joint venture with a PREI-managed fund, which did not materially impact our results of operations for the three and nine months ended September 30, 2013.

As shown by the same store and new properties table below, the increases in rental revenues and tenant reimbursement revenues in the three and nine months ended September 30, 2013 compared to the same periods in 2012 were due to new leasing at our same store properties, including completed and leased development space, and acquisitions of properties. Other revenues changes in the periods presented were primarily due to tenant termination revenues. We acquired 11 properties during the twelve months ended September 30, 2013.

The following tables show total operating revenues for same store properties and new properties (in thousands).

Same store rental revenues increased for the three and nine months ended September 30, 2013 compared to the same periods in 2012 primarily as a result of new leases at our properties during the twelve months ended September 30, 2013, including leases of completed development space, the largest of which was for space in 29A International Business Park, 3825 NW Aloclek Place and 98 Radnor Drive. Same store growth was driven by the delivery of approximately 425,000 square feet of leased data center space from within our same store development platform during the last 12 months. In our same store

portfolio, we calculate the change in rental rates on renewals signed during the quarter as compared to the previous rent on that same space. During the twelve months ended September 30, 2013, the percentage increase was 16.7% on a GAAP basis. Same store rental revenues increased for the three and nine months ended September 30, 2013 as compared to the same periods in 2012 as a result of the increase in rentable square feet of leased data center space. During the twelve months ended September 30, 2013, we also delivered approximately 323,000 square feet of un-leased data center space which was one of the drivers impacting occupancy which decreased slightly to 91.8% as of September 30, 2013 from 93.2% as of September 30, 2012. Rental revenue included amounts earned from leases with The tel(x) Group, Inc., or tel(x), which was sold to an unrelated third party in 2011, of approximately $15.6 million and $12.0 million for the three months ended September 30, 2013 and 2012, respectively, and approximately $44.0 million and $33.7 million for the nine months ended September 30, 2013 and 2012, respectively. Same store tenant reimbursement revenues increased for the three and nine months ended September 30, 2013 as compared to the same periods in 2012 primarily as a result of new leasing and higher utility and operating expenses being billed to our tenants, the largest occurrences of which were at 29A International Business Park, 365 South Randolphville Road and 350 East Cermak Road.

New properties revenue increases were caused by properties acquired during the period from January 1, 2012 to September 30, 2013. For the three and nine months ended September 30, 2013, the Sentrum Portfolio, the Paris Portfolio, 400 S. Akard, 11900 East Cornell and 1500 Towerview Road contributed $11.4 million, or approximately 71%, and $96.1 million, or approximately 88%, respectively, of the new properties increase in rental revenues and tenant reimbursements compared to the same periods in 2012.

As shown in the same store and new properties table below, total expenses for the three and nine months ended September 30, 2013 increased compared to the same periods in 2012 primarily as a result of higher utility rates in several of our properties along with development projects being placed into service leading to higher utility expense in 2013. The following table shows expenses for new properties (properties that were acquired after December 31, 2011) and same store properties (all other properties) (in thousands).

Same store rental property operating and maintenance expenses increased in the three and nine months ended September 30, 2013 compared to the same periods in 2012 primarily as a result of higher consumption and utility rates in several of our properties along with development projects being placed into service leading to higher utility expense in 2013. During the three months ended September 30, 2013, a non-cash $10.0 million straight-line rent expense adjustment was recorded in rental property operating and maintenance expenses related to a lease amendment executed in September 2010. This cumulative adjustment had an approximate quarterly impact of $830,000 to our earnings. This adjustment is deemed to be immaterial to the financial statements taken as a whole from a cumulative basis, as well as on a per period basis.

Same store property taxes increased by approximately $5.6 million and $9.6 million, respectively, in the three and nine months ended September 30, 2013 compared to the same periods in 2012, primarily as a result of additional personal property tax assessments in our Santa Clara, California and Texas properties in the quarter ended September 30, 2013.

During the three months ended September 30, 2013 and 2012, we capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $9.7 million and $8.0 million, respectively, and $29.4 million and $23.3 million during the nine months ended September 30, 2013 and 2012, respectively.

Same store depreciation and amortization expense increased in the three and nine months ended September 30, 2013 compared to the same periods in 2012, principally because of depreciation of development projects that were placed into service in late 2012 and during 2013.

General and administrative expenses for the three and nine months ended September 30, 2013 increased compared to the same periods in 2012 primarily due to the growth of our company, which resulted in more employees, additional incentive compensation, and higher professional fees and marketing expenses.

Same store interest expense increased for the three and nine months ended September 30, 2013 as compared to the same periods in 2012 primarily as a result of the issuance of our 3.625% Notes due 2022 (2022 Notes) in September 2012 offset by lower average outstanding mortgage debt balances during 2013 compared to 2012 primarily due to the paydown of the following loans: 114 Rue Ambroise Croizat (January 2012), Unit 9, Blanchardstown Corporate Park (January 2012), 1201 Comstock Street (April 2012), 2805 Lafayette Street (May 2012), 2805 Lafayette Street Mezzanine (May 2012), 1350 Duane Avenue/3080 Raymond Street (September 2012) Clonshaugh Industrial Estate II (June 2013), 1500 Space Park Drive (July 2013), Paul van Vlissingenstraat 16 (July 2013) and Chemin de l’Epinglier 2 (July 2013). During the three months ended September 30, 2013 and 2012, we capitalized interest of approximately $6.9 million and $4.5 million, respectively, and $18.8 million and $13.6 million during the nine months ended September 30, 2013 and 2012, respectively.

New properties increases were caused by properties acquired during the period from January 1, 2012 to September 30, 2013. For the three and nine months ended September 30, 2013, the Sentrum Portfolio, 400 S. Akard and 9333, 9355 and 9377 Grand Avenue contributed $3.5 million, or approximately 31%, and $54.7 million, or approximately 78%, of the total new properties increase in total operating expenses (excluding construction management) compared to the same periods in 2012.

New properties interest expense increased for the three and nine months ended September 30, 2013 as compared to the same periods in 2012 primarily as a result of the issuance of Digital Stout Holding, LLC’s 4.250% Notes due 2025 in January 2013.

Transactions expense decreased in the three and nine months ended September 30, 2013 compared to the same periods in 2012, principally because of expenses related to the Sentrum Portfolio acquisition in 2012.

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 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 shares. 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 April 23, 2012 that allows our parent company to register unspecified various classes of equity securities. As 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 be generally 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 preferred 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’, 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 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 its ability to make 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.

On June 29, 2011, our parent company commenced an At-the-Market equity distribution program under which it can issue and sell up to $400.0 million of its common stock through, at its discretion, any 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 as its sales agents. For the nine months ended September 30, 2012, our parent company generated net proceeds of approximately $62.7 million from the issuance of approximately 1.0 million shares of common stock under the program at an average price of $66.19 per share after payment of approximately $0.6 million of commissions to the sales agents. The proceeds from the issuances were contributed to our operating partnership in exchange for the issuance of approximately 1.0 million common units to our parent company. No sales were made under the program during the nine months ended September 30, 2013. The sales of common stock under the equity distribution program will be made in “at the market” offerings as defined in Rule 415 of the Securities Act. As of September 30, 2013, shares of common stock having an aggregate offering price of $53.8 million remained available for offer and sale under the program.

On January 18, 2013, Digital Stout Holding, LLC, a wholly-owned subsidiary of Digital Realty Trust, L.P., issued £400.0 million (or approximately $634.8 million based on the exchange rate of £1.00 to $1.59 on January 18, 2013) aggregate principal amount of its 4.250% Guaranteed Notes due 2025, or the 2025 notes. The 2025 Notes are senior unsecured obligations of Digital Stout Holding, LLC and are fully and unconditionally guaranteed by the parent company and our operating partnership. Interest on the 2025 notes is payable semiannually in arrears at a rate of 4.250% per annum. The net proceeds from the offering after deducting the original issue discount of approximately $4.8 million and underwriting commissions and estimated expenses of approximately $5.8 million was approximately $624.2 million. We used the net proceeds from this offering to temporarily repay borrowings under our global revolving credit facility.

Effective February 26, 2013, our parent company converted all outstanding shares of its series D preferred stock into shares of our parent company’s common stock in accordance with the terms of the series D preferred stock. Each share of series D preferred stock was converted into 0.6360 shares of our parent company’s common stock. In connection with this conversion, our operating partnership issued 3,054,186 common units to our parent company upon conversion of 4,802,180 series D cumulative convertible preferred units.

On April 9, 2013, our parent company issued an aggregate of 10.0 million shares of its 5.875% Series G Cumulative Redeemable Preferred Stock for total net proceeds, after underwriting discounts and estimated offering expenses, of $241.6 million, including the proceeds from the partial exercise of the underwriters’ over-allotment option. We have used the net proceeds from the offering to temporarily repay borrowings under our global revolving credit facility.

On October 23, 2013, our parent company’s board of directors authorized a share repurchase program under which our parent company may repurchase up to $500.0 million of its outstanding common stock, which our parent company may use to opportunistically reacquire shares on the open market or in privately negotiated transactions or otherwise, based on the then-current share price and capital allocation alternatives.

Future Uses of Cash

Our parent company may from time to time seek to retire, redeem or repurchase its preferred equity or the debt securities of our operating partnership 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. The exchange rate on the operating partnership’s 5.50% exchangeable senior debentures due 2029 (2029 Debentures) is subject to adjustment for certain events, including, but not limited to, certain dividends on our parent company’s common stock in excess of $0.33 per share per quarter. Therefore, the declaration and payment of quarterly dividends by our parent company in excess of these thresholds may increase the dilutive impact of the 2029 Debentures on our parent company’s common stockholders.

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 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 operating partnership’s 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, 2013 (in thousands):


Date dividend declared	Dividend payable date	Series E Preferred Stock ⁽¹⁾		Series F Preferred Stock ⁽²⁾		Series G Preferred Stock⁽³⁾			Common Stock ⁽⁴⁾
February 12, 2013	March 29, 2013	$	5,031	$	3,023	$	—		$	100,165
May 1, 2013	June 28, 2013		5,031		3,023		3,345	⁽⁵⁾		100,169
July 23, 2013	September 30, 2013		5,031		3,023		3,672			100,180

		$	15,093	$	9,069	$	7,017		$	300,514

(1)	$1.750 annual rate of dividend per share.

(2)	$1.656 annual rate of dividend per share.

(3)	$1.469 annual rate of dividend per share.

(4)	$3.120 annual rate of dividend per share.

(5)	Represents a pro rata dividend from and including the original issue date to and including June 30, 2013.

Distributions out of our current or accumulated earnings and profits are generally classified as ordinary income whereas distributions in excess of our 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 the sole general partner of our operating partnership 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, 2013, we had $55.1 million of cash and cash equivalents, excluding $42.5 million of restricted cash. Restricted cash primarily consists of interest-bearing cash deposits required by the terms of several of our mortgage loans for a variety of purposes, including real estate taxes, insurance, anticipated or contractually obligated tenant improvements, as well as capital expenditures.

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 in our operating partnership, capital expenditures, debt service on our loans 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 August 15, 2013, the Operating Partnership refinanced its revolving credit facility, which we refer to as the global revolving credit facility, increasing its total borrowing capacity to $2.0 billion from $1.8 billion. The global revolving credit facility has an accordion feature that would enable us to increase the borrowing capacity of the credit facility to $2.55 billion, subject to the receipt of lender commitments and other conditions precedent. The refinanced facility matures on November 3, 2017, with two six-month extension options. The interest rate for borrowings under the expanded facility equals the applicable index plus a margin which is based on the credit rating of our long-term debt and is currently 110 basis points. An annual facility fee on the total commitment amount of the facility, based on the credit rating of our long-term debt and currently 20 basis points, is payable quarterly. In the event our current credit ratings are downgraded, we may incur higher borrowing costs. Funds may be drawn in U.S., Canadian, Singapore, Australian and Hong Kong dollars, as well as Euro, British pound sterling, Swiss franc and Japanese yen denominations. As of September 30, 2013, borrowings under the global revolving credit facility bore interest at a blended rate of 1.66% comprised of 1.36% (U.S. dollars), 1.60% (British pound sterling), 1.23% (Euros), 3.66% (Australian dollars), 1.31% (Hong Kong dollars), 1.22% (Japanese yen) and 2.32% (Canadian dollars). The interest rates are based on 1-month LIBOR, 1-month GBP LIBOR, 1-month EURIBOR, 1-month BBR, 1-month HIBOR, 1-month JPY LIBOR and 1-month CAD LIBOR, respectively, plus a margin of 1.10%. We have used and intend to use available borrowings under the global revolving credit facility to acquire additional properties, fund development opportunities and to provide for working capital and other corporate purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or preferred equity securities. As of September 30, 2013, we have capitalized approximately $17.6 million of financing costs related to the global revolving credit facility. As of September 30, 2013, approximately $498.1 million was drawn under this facility and $20.3 million of letters of credit were issued, leaving approximately $1.5 billion available for use.

On August 15, 2013, we refinanced the senior unsecured multi-currency term loan facility, increasing its total borrowing capacity to $1.0 billion from $750.0 million, and pursuant to the accordion feature total commitments can be increased up to $1.1 billion, subject to the receipt of lender commitments and other conditions precedent. The facility matures on April 16, 2017, with two six-month extension options. Interest rates are based on our senior unsecured debt ratings and are currently 120 basis points over the applicable index for floating rate advances. In the event our current credit ratings are downgraded, we may incur higher borrowing costs. Funds may be drawn in U.S, Singapore and Australian dollars, as well as Euro and British pound sterling denominations with the option to add Hong Kong dollars and Japanese yen upon an accordion exercise. Based on exchange rates in effect at September 30, 2013, the balance outstanding is approximately $950.2 million. We have used borrowings under the term loan for acquisitions, repayment of indebtedness, development, working capital and general corporate purposes. The covenants under this loan are consistent with our global revolving credit facility and, as of September 30, 2013, we were in compliance with all of such covenants. As of September 30, 2013, we have capitalized approximately $8.4 million of financing costs related to the unsecured term loan.

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.

On June 29, 2011, our parent company commenced its new At-the-Market equity distribution program discussed under “Liquidity and Capital Resources of the Parent Company” above. For the nine months ended September 30, 2012, our parent company generated net proceeds of approximately $62.7 million from the issuance of approximately 1.0 million shares of common stock under the program at an average price of $66.19 per share after payment of approximately $0.6 million of commissions to the sales agents. The proceeds from the issuances were contributed to us in exchange for the issuance of approximately 1.0 million common units to our parent company. No sales were made under the program during the nine months ended September 30, 2013. As of September 30, 2013, shares of common stock having an aggregate offering price of $53.8 million remained available for offer and sale under the program.

On January 18, 2013, Digital Stout Holding, LLC, a wholly-owned subsidiary of our operating partnership, issued £400.0 million (or approximately $634.8 million based on the exchange rate of £1.00 to $1.59 on January 18, 2013) aggregate principal amount of its 4.250% Guaranteed Notes due 2025, or the 2025 notes. The 2025 Notes are senior unsecured obligations of Digital Stout Holding, LLC and are fully and unconditionally guaranteed by our parent company and our operating partnership. Interest on the 2025 notes is payable semiannually in arrears at a rate of 4.250% per annum. The net proceeds from the offering after deducting the original issue discount of approximately $4.8 million and underwriting commissions and estimated expenses of approximately $5.8 million was approximately $624.2 million. We used the net proceeds from this offering to temporarily repay borrowings under our global revolving credit facility.

On January 31, 2013, we completed the acquisition of two properties for an aggregate purchase price of $32.5 million. One property is a 61,750 square foot data center and is located in the Dallas metropolitan area. The other property consists of three buildings totaling approximately 227,000 square feet and is located in the Phoenix metropolitan area. Two of the buildings are non-technical single tenant sale-leasebacks and the third building will be developed. The acquisitions were financed with borrowings under our global revolving credit facility.

On March 11, 2013, we made an initial investment of $12.5 million in a data center, network and IT services company in Mexico. This investment represents our entrance into the Mexican market. An additional investment of approximately $4.7 million was made in April 2013. The investments were financed with borrowings under our global revolving credit facility.

On March 12, 2013, we completed the acquisition of a 120,000 square foot data center development property for C$8.65 million (or approximately $8.4 million based on the March 12, 2013 exchange rate of $1.00 to C$1.03). The property is located in the Toronto metropolitan area. The acquisition was financed with borrowings under our global revolving credit facility.

On March 27, 2013, we completed the acquisition of a 329,000 square foot data center for $37.0 million. The property is located in the Minneapolis metropolitan area and is structured as a sale-leaseback transaction. The acquisition was financed with borrowings under our global revolving credit facility.

On April 2, 2013, we acquired a three-acre land site in London for a previously signed build-to-suit agreement for a purchase price of $3.6 million. The acquisition was financed with borrowings under our global revolving credit facility.

On May 20, 2013, we completed the acquisition of a six-building portfolio consisting of operating data centers and flex office space totaling approximately 337,000 square feet for $31.9 million. The property is located in the Austin metropolitan area. The acquisition was financed with borrowings under our global revolving credit facility.

On June 27, 2013, we completed a sale leaseback transaction for a partially-built data center in Groningen, Netherlands for a purchase price of $3.9 million. We paid an additional $2.6 million in October 2013 upon completion of construction by the tenant with a final payment of $1.3 million expected to be paid in November 2013. This initial development will total approximately 16,800 square feet of space. The acquisition was financed with borrowings under our global revolving credit facility.

On August 9, 2013, we acquired a 3.7 acre land site in Osaka, Japan for a purchase price of $9.6 million. The acquisition was financed with borrowings under our global revolving credit facility.

On September 23, 2013, we acquired an 11.8 acre land site in London for a previously signed build-to-suit agreement for a purchase price of $19.2 million. The acquisition was financed with borrowings under our global revolving credit facility.

On September 24, 2013, we acquired a 5.4 acre land site in Amsterdam for a purchase price of $6.7 million. The acquisition was financed with borrowings under our global revolving credit facility.

The weighted average cash capitalization rate on income-producing properties, excluding development projects, acquired during the nine months ended September 30, 2013 was 10.0%. We calculate the cash capitalization rate on acquisitions by dividing anticipated annual net operating income by the purchase price (including assumed debt). Net operating income represents rental revenue and tenant reimbursement revenue from in place leases less rental property operating and maintenance expenses, property taxes and insurance expenses and is not a financial measure calculated in accordance with GAAP. Our calculation of the weighted average cash capitalization rate for acquisitions may change based on our experience operating the properties following the closing of the acquisitions. The growing acceptance by private institutional investors of the data center asset class has generally pushed capitalization rates lower, as such private investors typically have lower return expectations than us. As a result, we anticipate that near-term acquisitions activity will comprise a smaller percentage of our growth until seller price expectations realign with our return requirements.

On September 27, 2013, we formed a joint venture with an investment fund managed by Prudential Real Estate Investors (PREI^®). We contributed nine Powered Base Building^® data centers totaling 1.06 million square feet and valued at approximately $366.4 million (excluding $2.8 million of closing costs). The PREI^®-managed fund took an 80% interest in the joint venture and we retained a 20% interest. The joint venture is structured to provide a current annual preferred return from cash flow first to the PREI^®-managed interest, then to our interest, after which a portion of any excess cash flows is shared by the partners based on their respective interests and the remaining portion is paid to us as a promote interest. We will perform the day-to-day accounting and property management functions for the joint venture and, as such, will earn a management fee for the services provided. Although we are the managing member of the joint venture and manage the day-to-day activities, all significant decisions, including approval of annual budgets and setting the amount of our management fees require approval of the PREI^® member. Thus we concluded we do not own a controlling interest and will account for our interest in the joint venture as an equity method investment.

Construction

As of September 30, 2013, the balance of construction work in progress was $909.5 million, which included 1.5 million square feet of Turn Key Flex^SM, Custom Solutions and Powered Base Buildings^® construction projects with a cost including accruals of $266.7 million. Cost of work on buildings, sites, and other improvements associated with specific space under construction was $301.8 million. The expected cost to complete the work on the 1.5 million square feet of specific space and associated building, site, and other improvement projects under construction is $561.1 million for a total expected cost of approximately $1.1 billion with completion expected in the next twelve months. Including the proportionate acquisition cost, capitalized interest, and capitalized general and administrative costs, the expected total cost of work associated with the delivery of the above projects is approximately $2.0 billion.

As of December 31, 2012, the balance of construction work in progress was $641.7 million, which included 1.4 million square feet of Turn Key Flex^SM, Custom Solutions and Powered Base Buildings^® construction projects with a cost including accruals of $135.4 million. Cost of work on buildings, sites, and other improvements associated with specific space under construction was $156.6 million. The expected cost to complete the work on the 1.4 million square feet of specific space and associated building, site, and other improvement projects under construction was $599.0 million for a total expected cost of $891.0 million. Including the proportionate acquisition cost, capitalized interest, and capitalized general and administrative costs, the expected total cost of work associated with the delivery of the above projects was approximately $1.6 billion.

In May 2013, we received insurance settlement proceeds of approximately $8.6 million related to disputed construction costs, a portion of which has been recorded as a gain on settlement in our condensed consolidated income statement included elsewhere in this report.

Future Uses of Cash

At September 30, 2013, approximately 1,533,000 square feet was under construction for Turn-Key Flex^SM, Powered Base Building^® and Custom Solutions (formerly referred to as Build-to-Suit) products, all of which are expected to be income producing on or after completion, in 10 U.S. markets, two European markets, one Canadian market and one Australian market, consisting of approximately 691,000 square feet of space under development projects and 842,000 square feet of land under development projects. At September 30, 2013, we had commitments under construction contracts for approximately $191.7 million. We currently expect to incur approximately $250.0 million to $325.0 million of capital expenditures for our development programs during the three months ending December 31, 2013, although this amount may increase or decrease, potentially by a material amount, based on numerous factors, including changes in demand, leasing results and availability of debt or equity capital.

Our operating properties require periodic investments of capital for enhancement and improvement including tenant-related capital expenditures. As of September 30, 2013, we had approximately 2.8 million square feet of space held for development and we also owned approximately 571,000 square feet of datacenter space with extensive installed tenant improvements available for lease. Depending on demand for additional Turn-Key Flex^SM space, we expect to incur significant tenant improvement costs to build out and develop this type of space. Turn-Key Flex^SM space is move-in-ready space for the placement of computer and network equipment required to provide a datacenter environment.

Historical Capital Expenditures (Cash Basis)


	Nine Months Ended September 30,
	2013		2012
Development projects	$	721,718	$	452,464
Enhancement and improvements		78,730		78,092
Recurring capital expenditures		36,184		26,998

Total capital expenditures (excluding indirect costs)	$	836,632	$	557,554

For the nine months ended September 30, 2013, total capital expenditures increased $279.1 million to $836.6 million from the nine months ended September 30, 2012. Capital expenditures on our development projects plus our enhancement and improvements projects for the nine months ended September 30, 2013 were approximately $800.4 million, which reflects an increase of approximately 51% from the same period in 2012. This increase was primarily due to increased spending for ground-up Custom Solutions projects, Turn-Key Flex^SM and base building improvements. Our development capital expenditures are generally funded by our available cash and equity and debt capital.

Indirect costs, including capitalized interest, capitalized in the nine months ended September 30, 2013 and September 30, 2012 were $48.2 million and $36.9 million, respectively. Capitalized interest comprised approximately $18.8 million and $13.6 million, respectively, of the total indirect costs capitalized for the nine months ended September 30, 2013 and September 30, 2012. Capitalized interest in the nine months ended September 30, 2013 increased compared to the same period in 2012 due to an increase in the value of qualifying activities in progress during the nine months ended September 30, 2013 as compared to the nine months ended September 30, 2012. Excluding capitalized interest, the increase in indirect costs in the nine months ended September 30, 2013 compared to the same period in 2012 was primarily due to capitalized amounts relating to compensation expense of employees directly engaged in construction and leasing activities. See “—Future Uses of Cash” for a discussion of the amount of capital expenditures we expect to incur during the year ending December 31, 2013.

We are in the process of analyzing the extent of the environmental cleanup work required at the 47700 Kato Road and 1055 Page Avenue property. We intend to seek recovery of costs related to this work from a prior tenant of the building and/or performance by the prior tenant of the required work. We cannot at this time estimate the magnitude of these costs, the likelihood of recovery or the impact on our financial condition and results of operations, however, the amounts are not expected to be material.

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, 2013 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 preferred 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- and long-term liquidity requirements, including to pay for scheduled debt maturities and to fund property 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- and long-term liquidity requirements, including property 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.

Commitments and Contingencies

As part of the acquisition of the Sentrum Portfolio, the seller could earn additional consideration based on future net returns on vacant space to be developed, but not currently leased, as defined in the purchase agreement for the acquisition. The initial estimate of fair value of contingent consideration was approximately £56.5 million (or approximately $87.6 million based on the exchange rate as of July 11, 2012, the acquisition date). During the three months ended March 31, 2013, we made certain immaterial corrections to the initial measurement of the accrued contingent consideration that resulted in an additional $5.8 million of purchase price allocated to investments in real estate. These corrections had no impact on reported net income for the period. We have adjusted the contingent consideration to fair value at each reporting date with changes in fair value recognized in operating income. At September 30, 2013, the fair value of the contingent consideration for Sentrum was £45.2 million (or approximately $73.1 million based on the exchange rate as of September 30, 2013) and is currently accrued in accounts payable and other accrued expenses in the condensed consolidated balance sheet. During the nine months ended September 30, 2013, we have made earnout payments of approximately £16.9 million (or approximately $25.8 million based on the exchange rates as of the date of each payment). Change in fair value of contingent consideration for Sentrum was an increase to operating income of approximately $0.9 million and $13,000 for the three and nine months ended September 30, 2013, respectively. The earn-out contingency expires in July 2015. This amount will be reassessed on a quarterly basis, with any changes being recognized in earnings. Increases or decreases in the fair value of the contingent consideration can result from changes in discount periods, discount rates and probabilities that contingencies will be met.

As of September 30, 2013, we were a party to interest rate swap agreements which hedge variability in cash flows related to LIBOR, GBP LIBOR and EURIBOR based mortgage loans as well as the U.S. LIBOR and SGD-SOR based tranches of the unsecured term loan. Under these swaps, we pay variable-rate amounts in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying principal amounts. See Item 3 “Quantitative and Qualitative Disclosures about Market Risk.”

(1)	Excludes impact of deferred financing cost amortization.

As of September 30, 2013, we had approximately $4.8 billion of outstanding consolidated long-term debt as set forth in the table above. Our ratio of debt to total enterprise value was approximately 38% (based on the closing price of Digital Realty Trust, Inc.’s common stock on September 30, 2013 of $53.10). 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), excluding options issued under our incentive award plan, 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 and Class C 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, SIBOR, BBR, HIBOR, JPY LIBOR and CAD LIBOR rates, depending on the respective agreement governing the debt, including our global revolving credit facility and unsecured term loan. Assuming maturity of the 2029 Debentures at its first redemption date in April 2014, as of September 30, 2013, our debt had a weighted average term to initial maturity of approximately 5.0 years (approximately 5.3 years assuming exercise of extension options).

Off-Balance Sheet Arrangements

As of September 30, 2013, we were party to interest rate swap agreements related to $639.7 million of outstanding principal on our variable rate debt. See Item 3 “Quantitative and Qualitative Disclosures about Market Risk.”

As of September 30, 2013, our pro-rata share of mortgage debt of unconsolidated joint ventures was approximately $113.7 million.

Cash Flows

The following summary discussion of our cash flows is based on the consolidated statements of cash flows and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.

Comparison of Nine Months Ended September 30, 2013 to Nine Months Ended September 30, 2012

The following table shows cash flows and ending cash and cash equivalent balances for the nine months ended September 30, 2013 and 2012 (in thousands).


	Nine Months Ended September 30,
	2013			2012			Change
Net cash provided by operating activities	$	454,080		$	356,536		$	97,544
Net cash used in investing activities		(732,501	)		(2,084,928	)		1,352,427
Net cash provided by financing activities		277,258			1,763,876			(1,486,618	)

Net (decrease) increase in cash and cash equivalents	$	(1,163	)	$	35,484		$	(36,647	)

The increase in net cash provided by operating activities was due to increased cash flows from new leasing at our same store properties, completed and leased development space and our acquisition of new operating properties, which was partially offset by increased operating and interest expenses. Net cash used in investing activities decreased for the nine months ended September 30, 2013, as we had a decrease in cash paid for acquisitions for the nine months ended September 30, 2013 ($154.8 million) as compared to the same period in 2012 ($1.5 billion), along with proceeds from the contribution of nine properties to our joint venture with a PREI-managed fund ($328.6 million), which was partially offset by an increase in cash paid for capital expenditures for the nine months ended September 30, 2013 ($882.3 million) as compared to the same period in 2012 ($596.6 million).

Net cash flows from financing activities for the company consisted of the following amounts (in thousands).


	Nine Months Ended September 30,
	2013			2012			Change
Proceeds from borrowings, net of repayments	$	(136,938	)	$	799,070		$	(936,008	)
Net proceeds from issuance of common and preferred stock, including exercise of stock options		241,188			1,040,155			(798,967	)
Net proceeds from 2025 Notes		630,026			—			630,026
Net proceeds from 2022 Notes		—			296,052			(296,052	)
Dividend and distribution payments		(432,132	)		(363,351	)		(68,781	)
Other		(24,886	)		(8,050	)		(16,836	)

Net cash provided by financing activities	$	277,258		$	1,763,876		$	(1,486,618	)

The decrease in net cash provided by financing activities was primarily due to net borrowings during the nine months ended September 30, 2012 (net proceeds of $799.1 million) as compared to the nine months ended September 30, 2013 (net payments of $136.9 million), the issuance of Digital Realty Trust, Inc.’s common stock in its underwritten public offering in July 2012 (net proceeds of $797.2 million) along with the issuance of our 2022 Notes (net proceeds of $296.1 million) in September 2012 offset by the issuance of our 2025 Notes in January 2013 (net proceeds of $630.0 million). The increase in dividend and distribution payments for the nine months ended September 30, 2013 as compared to the same period in 2012 was due to an increase in the number of shares outstanding and dividend amount per share of common stock in 2013 as compared to 2012 and the payment of dividends on our series F and series G preferred stock during the nine months ended September 30, 2013, whereas these series of preferred stock were not outstanding during the entire nine months ended September 30, 2012.

Net cash flows from financing activities for the operating partnership consisted of the following amounts (in thousands).


	Nine Months Ended September 30,
	2013			2012			Change
Proceeds from borrowings, net of repayments	$	(136,938	)	$	799,070		$	(936,008	)
General partner contributions, net		241,188			1,040,155			(798,967	)
Net proceeds from 2025 Notes		630,026			—			630,026
Net proceeds from 2022 Notes		—			296,052			(296,052	)
Distribution payments		(432,132	)		(363,351	)		(68,781	)
Other		(24,886	)		(8,050	)		(16,836	)

Net cash provided by financing activities	$	277,258		$	1,763,876		$	(1,486,618	)

The decrease in net cash provided by financing activities was primarily due to net borrowings during the nine months ended September 30, 2012 (net proceeds of $799.1 million) as compared to the nine months ended September 30, 2013 (net payments of $136.9 million), general partner contributions in connection with Digital Realty Trust, Inc.’s common stock offering in July 2012 (net contributions of $797.2 million) and the issuance of our 2022 Notes (net proceeds of $296.1 million) in September 2012 offset by the issuance of the 2025 Notes (net proceeds of $630.0 million) in January 2013. The increase in distribution payments for the nine months ended September 30, 2013 as compared to the same period in 2012 was due to an increase in the number of units outstanding and distribution amount per common unit in 2013 as compared to 2012 and the payment of distributions on our series F and series G preferred units during the nine months ended September 30, 2013, whereas these series of preferred units were not outstanding during the entire nine months ended September 30, 2012.

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, 2013, amounted to 2.3% of our operating partnership common units. In conjunction with our formation, GI Partners received common units, in exchange for contributing ownership interests in properties to our operating partnership. Also, our operating partnership issued common units to third party sellers in connection with our acquisition of real estate interests from such third parties. In addition, executives and directors receive equity awards in the form of common units.

Limited partners who acquired common units in connection with our formation 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. Pursuant to registration rights agreements we entered into with GI Partners and the other third party contributors, we filed a shelf registration statement covering the issuance of the shares of our common stock issuable upon redemption of the common units, and the resale of those shares of common stock by the holders. As of March 31, 2007, GI Partners no longer had an ownership interest in our operating partnership.

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) available to common stockholders (computed in accordance with U.S. GAAP), excluding gains (or losses) from sales of property, impairment charges, 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, 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 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. Accordingly, FFO should be considered only as a supplement to net income 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, 2013, our consolidated debt was as follows (in millions):


	Carrying Value		Estimated Fair Value
Fixed rate debt	$	3,254.2	$	3,464.6
Variable rate debt subject to interest rate swaps		639.7		640.0

Total fixed rate debt (including interest rate swaps)		3,893.9		4,104.6
Variable rate debt		886.5		886.5

Total outstanding debt	$	4,780.4	$	4,991.1

Interest rate swaps and their fair values as of September 30, 2013 and December 31, 2012 were as follows (in thousands):


Notional Amount															Fair Value at Significant Other Observable Inputs (Level 2)
As of September 30, 2013			As of December 31, 2012			Type of Derivative		Strike Rate		Effective Date		Expiration Date			As of September 30, 2013			As of December 31, 2012

(1)	Translation to U.S. dollars is based on exchange rate of $1.62 to £1.00 as of September 30, 2013 and $1.63 to £1.00 as of December 31, 2012.

(2)	Translation to U.S. dollars is based on exchange rate of $1.35 to €1.00 as of September 30, 2013 and $1.32 to €1.00 as of December 31, 2012.

(3)	Represents the U.S. dollar tranche of the unsecured term loan.

(4)	Represents the Singapore dollar tranche of the unsecured term loan. Translation to U.S. dollars is based on exchange rate of $0.80 to 1.00 SGD as of September 30, 2013 and $0.82 to 1.00 SGD as of December 31, 2012.

(5)	The swap agreements were terminated as the mortgage loans were paid in full in July 2013.

(6)	The swap agreement was terminated as the mortgage loan was paid in full in June 2013.

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, 2013:


Assumed event	Interest rate change (basis points)			Change ($ millions)
Increase in fair value of interest rate swaps following an assumed 10% increase in interest rates		8		$	1.4
Decrease in fair value of interest rate swaps following an assumed 10% decrease in interest rates		(8	)		(1.4	)
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		8			0.7
Decrease in annual interest expense on our debt that is variable rate and not subject to swapped interest following a 10% decrease in interest rates		(8	)		(0.7	)
Increase in fair value of fixed rate debt following a 10% decrease in interest rates		(8	)		12.2
Decrease in fair value of fixed rate debt following a 10% increase in interest rates		8			(11.8	)

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 three and nine months ended September 30, 2013 and 2012, we had foreign operations in the United Kingdom, Ireland, France, The Netherlands, Switzerland, Canada, Singapore, Australia and Hong Kong as well as Japan in the three months ended September 30, 2013, 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, Swiss franc, 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, 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 and the amount of stockholders’ equity. For the three months ended September 30, 2013 and 2012, operating revenues from properties outside the United States contributed $85.4 million and $72.3 million, respectively, which represented 22.5% and 21.1% of our operating revenues, respectively, and for the nine months ended September 30, 2013 and 2012, operating revenues from properties outside the United States contributed $256.3 million and $151.0 million, respectively, which represented 23.3% and 16.2% of our operating revenues, respectively. Net investment in properties outside the United States was $2.6 billion and $2.5 billion as of September 30, 2013 and December 31, 2012, 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. Also, the company has investments in certain unconsolidated entities, which are accounted for using the equity method of accounting. As the company does not control or manage these entities, its disclosure controls and procedures with respect to such entities may be substantially more limited than those it maintains with respect to its consolidated subsidiaries.

As required by Rule 13a-15(b) or Rule 15d-15(b) of the Securities Exchange Act of 1934, as amended, management of the company carried out an evaluation, under the supervision and with participation of its chief executive officer and chief financial officer, of the effectiveness of the design and operation of its disclosure controls and procedures that were in effect as of the end of the quarter covered by this report. Based on the foregoing, the company’s chief executive officer and chief financial officer each concluded that its disclosure controls and procedures were effective at the reasonable assurance level.

There have been no changes in the company’s internal control over financial reporting during its most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
