		•		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 few differences between the Company and the Operating Partnership, which are reflected in these 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 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 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 consolidated financial statements and as noncontrolling interests in operating partnership within equity in Digital Realty Trust, Inc.’s 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 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 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:
		•		consolidated face financial statements; and
		•		the following notes to the consolidated financial statements:
		•		Debt of the Company and Debt of the Operating Partnership;
		•		Income per Share and Income per Unit;
		•		Equity and Accumulated Other Comprehensive Income (Loss), Net of the Company and Capital and Accumulated Other Comprehensive Income (Loss) of the Operating Partnership; and
		•		Quarterly Financial Information.
	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 consolidated statements of cash flows, we consider short-term investments with original maturities of 90 days or less to be cash equivalents. As of December 31, 2013 and 2012, cash equivalents consist of investments in money market instruments.
	(c) Investments in Real Estate
	Investments in real estate are stated at cost, less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives as follows:
	Acquired ground leases		Terms of the related lease
	Buildings and improvements		5-39 years
	Tenant improvements		Shorter of the estimated useful lives or the terms of the related leases
	Improvements and replacements are capitalized when they extend the useful life, increase capacity, or improve the efficiency of the asset. Repairs and maintenance are charged to expense as incurred.
	(d) Investment in Unconsolidated Joint Ventures
	The Company’s investment in unconsolidated joint ventures is accounted for using the equity method, whereby the investment is increased for capital contributed and our share of the joint ventures’ net income and decreased by distributions we receive and our share of any losses of the joint ventures.
	We amortize the difference between the cost of our investments in unconsolidated joint ventures and the book value of the underlying equity into equity in earnings from unconsolidated affiliates on a straight-line basis consistent with the lives of the underlying assets.
	(e) Impairment of Long-Lived Assets
	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 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. Management believes no impairment in the net carrying value of our investments in real estate has occurred.
	(f) Purchase Accounting for Acquisition of Investments in Real Estate
	Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired from third parties. In accordance with current accounting guidance,  the fair value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and tenant improvements, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases, value of tenant relationships and acquired ground leases, based in each case on their fair values. Loan premiums, in the case of above market rate loans, or loan discounts, in the case of below market loans, are recorded based on the fair value of any loans assumed in connection with acquiring the real estate.
	The fair values of the tangible assets of an acquired property are determined based on comparable land sales for land and replacement costs adjusted for physical and market obsolescence for the improvements. The fair values of the tangible assets of an acquired property are also determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land, building and tenant improvements based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a property based on assumptions that a market participant would use, which is similar to methods used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related costs.
	In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) estimated fair market lease rates from the perspective of a market participant for the corresponding in-place leases, measured, for above-market leases, over a period equal to the remaining non-cancelable term of the lease and, for below-market leases, over a period equal to the initial term plus any below market fixed rate renewal periods. The leases we have acquired do not currently include any below market fixed rate renewal periods. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. The capitalized below-market lease values, also referred to as acquired lease obligations, are amortized as an increase to rental income over the initial terms of the respective leases and any below market fixed rate renewal periods.
	In addition to the intangible value for above market leases and the intangible negative value for below market leases, there is intangible value related to having tenants leasing space in the purchased property, which is referred to as in-place lease value and tenant relationship value. Such value results primarily from the buyer of a leased property avoiding the costs associated with leasing the property and also avoiding rent losses and unreimbursed operating expenses during the lease up period. The estimated avoided costs and avoided revenue losses are calculated and this aggregate value is allocated between in-place lease value and tenant relationships based on management’s evaluation of the specific characteristics of each tenant’s lease; however, the value of tenant relationships has not been separated from in-place lease value for our real estate because such value and its consequence to amortization expense is immaterial for these particular acquisitions. The value of in-place leases exclusive of the value of above-market in-place leases is amortized to expense over the estimated term (including renewal and extension assumptions) of the respective leases. If a lease were to be terminated prior to its estimated term, all unamortized amounts relating to that lease would be written off.
	(g) 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.
	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. During the year ended December 31, 2013, the total incremental amounts capitalized that would have been recorded as rental property operating expense under our previous policies was approximately $9.5 million.
	During the years ended December 31, 2013, 2012 and 2011, we capitalized interest of approximately $26.3 million, $21.5 million and $17.9 million, respectively. During the years ended December 31, 2013, 2012 and 2011, we capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $37.6 million, $31.6 million and $24.7 million, respectively. Cash flows from capitalized leasing costs of $57.5 million, $40.1 million and $28.2 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 years ended December 31, 2013, 2012 and 2011, respectively.
	(h) Deferred Leasing Costs
	Leasing commissions and other direct and indirect costs associated with the acquisition of tenants are capitalized and amortized on a straight line basis over the terms of the related leases.
	(i) Foreign Currency Translation
	Assets and liabilities of our subsidiaries outside the United States with non-U.S. dollar functional currencies are translated into U.S. dollars using exchange rates as of the balance sheet dates. Income and expenses are translated using the average exchange rates for the reporting period. Foreign currency translation adjustments are recorded as a component of other comprehensive income.
	(j) Deferred Financing Costs
	Loan fees and costs are capitalized and amortized over the life of the related loans on a straight-line basis, which approximates the effective interest method. Such amortization is included as a component of interest expense.
	(k) Restricted Cash
	Restricted cash consists of deposits for real estate taxes and insurance and other amounts as required by our loan agreements including funds for leasing costs and improvements related to unoccupied space.
	(l) Offering Costs
	Underwriting commissions and other offering costs are reflected as a reduction in additional paid-in capital, or in the case of preferred stock, as a reduction of the carrying value of preferred stock.
	(m) 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.
	(n) Accounting for Derivative Instruments and Hedging Activities
	We account for our derivative instruments and hedging activities in accordance with the accounting standard for derivative and hedging activities. The accounting standard requires us to measure every derivative instrument (including certain derivative instruments embedded in other contracts) at fair value and record them in the balance sheet as either an asset or liability.
	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. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the years ended December 31, 2013, 2012 and 2011, respectively, there were no ineffective portions to our interest rate swaps.
	We actively manage our ratio of fixed-to-floating rate debt. To manage our fixed and floating rate debt in a cost-effective manner, we, from time to time, enter into interest rate swap agreements as cash flow hedges, under which we agree to exchange various combinations of fixed and/or variable interest rates based on agreed upon notional amounts. We do not enter into derivative instruments for trading purposes.
	(o) 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 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 U.S. 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 December 31, 2013 and 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 consolidated statements of operations. For the years ended December 31, 2013, 2012 and 2011, we had no such interest or penalties. The tax year 2010 and thereafter 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.
(p) 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.
(q) Revenue Recognition
All leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the terms of the leases. The excess of rents recognized over amounts contractually due pursuant to the underlying leases is included in deferred rent in the accompanying consolidated balance sheets and contractually due but unpaid rents are included in accounts and other receivables.
Tenant reimbursements for real estate taxes, common area maintenance, and other recoverable costs are recognized in the period that the expenses are incurred. Lease termination fees, which are included in other income in the accompanying statements of operations, are recognized over the new remaining term of the lease, effective as of the date the lease modification is finalized, and assuming collection is probable.
A provision for loss is made if the collection of the receivable balances related to contractual rent, rent recorded on a straight-line basis, tenant reimbursements and lease termination fees are considered to be doubtful.
(r) 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 December 31, 2013 and December 31, 2012, the amount included in accounts payable and other accrued liabilities on our consolidated balance sheets was approximately $1.7 million and $1.7 million, respectively.
(s) Fee Income
Occasionally, customers engage the company for certain consulting services.  The nature of these services historically involves property management, construction management, and assistance with financing.  The proper revenue recognition of these services can be different, depending on whether the arrangements are service revenue or contractor type revenue.
Service revenues are typically recognized on an equal monthly basis based on the minimum fee to be earned.  The monthly amounts could be adjusted depending on if certain performance milestones are met.
Fee income also includes management fees. These fees arise from contractual agreements with entities in which we have a noncontrolling interest. The management fees are recognized as earned under the respective agreements. Management and other fee income related to partially owned entities are recognized to the extent attributable to the unaffiliated interest.
Contractor type 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 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.
(t) 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.
(u) 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.
(v) Management’s Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates made. On an on-going basis, we evaluate our estimates, including those related to the valuation of our real estate properties, 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.
(w) 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 $1.1  billion, $1.1  billion and $946.0 million and outside the United States were $349.1 million, $228.9 million and $116.7 million for the years ended December 31, 2013, 2012 and 2011, respectively.  We had long-lived assets located in the United States of $5.6 billion, $5.0 billion and $4.3 billion and outside the United States of $2.7 billion, $2.5 billion and $1.0 billion as of December 31, 2013, 2012 and 2011, respectively.
Operating revenues from properties located in the United Kingdom were $197.0 million,  $117.2 million and $43.6 million, or 13.3%, 9.2% and 4.1% of total operating revenues for the years ended December 31, 2013, 2012 and 2011, respectively.  No other foreign country comprised more than 10% of total operating revenues for each of these years.  We had long-lived assets located in the United Kingdom of $1.8 billion, $1.7 billion and $356.0 million, or 21.1%, 22.3% and 6.8% of total long-lived assets as of December 31, 2013, 2012 and 2011, respectively.  No other foreign country comprised more than 10% of total long-lived assets as of each of December 31, 2013, 2012 and 2011.
(x) Recent Accounting Pronouncements
In 2013, the Financial Accounting Standards Board ("FASB") issued new accounting guidance clarifying the accounting for the release of a cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. We do not anticipate that this adoption will have a significant impact on our financial position, results of operations, or cash flows.
In 2013, the FASB issued new accounting guidance clarifying the accounting for obligations resulting from joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. We do not anticipate that this adoption will have a significant impact on our financial position, results of operations, or cash flows.

Summary Of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	(a) Principles of Consolidation and Basis of Presentation
	The accompanying 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 notes to the 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 few differences between the Company and the Operating Partnership, which are reflected in these 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 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 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 consolidated financial statements and as noncontrolling interests in operating partnership within equity in Digital Realty Trust, Inc.’s 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 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 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:
		•		consolidated face financial statements; and
		•		the following notes to the consolidated financial statements:
		•		Debt of the Company and Debt of the Operating Partnership;
		•		Income per Share and Income per Unit;
		•		Equity and Accumulated Other Comprehensive Income (Loss), Net of the Company and Capital and Accumulated Other Comprehensive Income (Loss) of the Operating Partnership; and
		•		Quarterly Financial Information.
	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 consolidated statements of cash flows, we consider short-term investments with original maturities of 90 days or less to be cash equivalents. As of December 31, 2013 and 2012, cash equivalents consist of investments in money market instruments.
	(c) Investments in Real Estate
	Investments in real estate are stated at cost, less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives as follows:
	Acquired ground leases		Terms of the related lease
	Buildings and improvements		5-39 years
	Tenant improvements		Shorter of the estimated useful lives or the terms of the related leases
	Improvements and replacements are capitalized when they extend the useful life, increase capacity, or improve the efficiency of the asset. Repairs and maintenance are charged to expense as incurred.
	(d) Investment in Unconsolidated Joint Ventures
	The Company’s investment in unconsolidated joint ventures is accounted for using the equity method, whereby the investment is increased for capital contributed and our share of the joint ventures’ net income and decreased by distributions we receive and our share of any losses of the joint ventures.
	We amortize the difference between the cost of our investments in unconsolidated joint ventures and the book value of the underlying equity into equity in earnings from unconsolidated affiliates on a straight-line basis consistent with the lives of the underlying assets.
	(e) Impairment of Long-Lived Assets
	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 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. Management believes no impairment in the net carrying value of our investments in real estate has occurred.
	(f) Purchase Accounting for Acquisition of Investments in Real Estate
	Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired from third parties. In accordance with current accounting guidance,  the fair value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and tenant improvements, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases, value of tenant relationships and acquired ground leases, based in each case on their fair values. Loan premiums, in the case of above market rate loans, or loan discounts, in the case of below market loans, are recorded based on the fair value of any loans assumed in connection with acquiring the real estate.
	The fair values of the tangible assets of an acquired property are determined based on comparable land sales for land and replacement costs adjusted for physical and market obsolescence for the improvements. The fair values of the tangible assets of an acquired property are also determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land, building and tenant improvements based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a property based on assumptions that a market participant would use, which is similar to methods used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related costs.
	In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) estimated fair market lease rates from the perspective of a market participant for the corresponding in-place leases, measured, for above-market leases, over a period equal to the remaining non-cancelable term of the lease and, for below-market leases, over a period equal to the initial term plus any below market fixed rate renewal periods. The leases we have acquired do not currently include any below market fixed rate renewal periods. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. The capitalized below-market lease values, also referred to as acquired lease obligations, are amortized as an increase to rental income over the initial terms of the respective leases and any below market fixed rate renewal periods.
	In addition to the intangible value for above market leases and the intangible negative value for below market leases, there is intangible value related to having tenants leasing space in the purchased property, which is referred to as in-place lease value and tenant relationship value. Such value results primarily from the buyer of a leased property avoiding the costs associated with leasing the property and also avoiding rent losses and unreimbursed operating expenses during the lease up period. The estimated avoided costs and avoided revenue losses are calculated and this aggregate value is allocated between in-place lease value and tenant relationships based on management’s evaluation of the specific characteristics of each tenant’s lease; however, the value of tenant relationships has not been separated from in-place lease value for our real estate because such value and its consequence to amortization expense is immaterial for these particular acquisitions. The value of in-place leases exclusive of the value of above-market in-place leases is amortized to expense over the estimated term (including renewal and extension assumptions) of the respective leases. If a lease were to be terminated prior to its estimated term, all unamortized amounts relating to that lease would be written off.
	(g) 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.
	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. During the year ended December 31, 2013, the total incremental amounts capitalized that would have been recorded as rental property operating expense under our previous policies was approximately $9.5 million.
	During the years ended December 31, 2013, 2012 and 2011, we capitalized interest of approximately $26.3 million, $21.5 million and $17.9 million, respectively. During the years ended December 31, 2013, 2012 and 2011, we capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $37.6 million, $31.6 million and $24.7 million, respectively. Cash flows from capitalized leasing costs of $57.5 million, $40.1 million and $28.2 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 years ended December 31, 2013, 2012 and 2011, respectively.
	(h) Deferred Leasing Costs
	Leasing commissions and other direct and indirect costs associated with the acquisition of tenants are capitalized and amortized on a straight line basis over the terms of the related leases.
	(i) Foreign Currency Translation
	Assets and liabilities of our subsidiaries outside the United States with non-U.S. dollar functional currencies are translated into U.S. dollars using exchange rates as of the balance sheet dates. Income and expenses are translated using the average exchange rates for the reporting period. Foreign currency translation adjustments are recorded as a component of other comprehensive income.
	(j) Deferred Financing Costs
	Loan fees and costs are capitalized and amortized over the life of the related loans on a straight-line basis, which approximates the effective interest method. Such amortization is included as a component of interest expense.
	(k) Restricted Cash
	Restricted cash consists of deposits for real estate taxes and insurance and other amounts as required by our loan agreements including funds for leasing costs and improvements related to unoccupied space.
	(l) Offering Costs
	Underwriting commissions and other offering costs are reflected as a reduction in additional paid-in capital, or in the case of preferred stock, as a reduction of the carrying value of preferred stock.
	(m) 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.
	(n) Accounting for Derivative Instruments and Hedging Activities
	We account for our derivative instruments and hedging activities in accordance with the accounting standard for derivative and hedging activities. The accounting standard requires us to measure every derivative instrument (including certain derivative instruments embedded in other contracts) at fair value and record them in the balance sheet as either an asset or liability.
	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. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the years ended December 31, 2013, 2012 and 2011, respectively, there were no ineffective portions to our interest rate swaps.
	We actively manage our ratio of fixed-to-floating rate debt. To manage our fixed and floating rate debt in a cost-effective manner, we, from time to time, enter into interest rate swap agreements as cash flow hedges, under which we agree to exchange various combinations of fixed and/or variable interest rates based on agreed upon notional amounts. We do not enter into derivative instruments for trading purposes.
	(o) 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 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 U.S. 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 December 31, 2013 and 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 consolidated statements of operations. For the years ended December 31, 2013, 2012 and 2011, we had no such interest or penalties. The tax year 2010 and thereafter 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.
(p) 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.
(q) Revenue Recognition
All leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the terms of the leases. The excess of rents recognized over amounts contractually due pursuant to the underlying leases is included in deferred rent in the accompanying consolidated balance sheets and contractually due but unpaid rents are included in accounts and other receivables.
Tenant reimbursements for real estate taxes, common area maintenance, and other recoverable costs are recognized in the period that the expenses are incurred. Lease termination fees, which are included in other income in the accompanying statements of operations, are recognized over the new remaining term of the lease, effective as of the date the lease modification is finalized, and assuming collection is probable.
A provision for loss is made if the collection of the receivable balances related to contractual rent, rent recorded on a straight-line basis, tenant reimbursements and lease termination fees are considered to be doubtful.
(r) 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 December 31, 2013 and December 31, 2012, the amount included in accounts payable and other accrued liabilities on our consolidated balance sheets was approximately $1.7 million and $1.7 million, respectively.
(s) Fee Income
Occasionally, customers engage the company for certain consulting services.  The nature of these services historically involves property management, construction management, and assistance with financing.  The proper revenue recognition of these services can be different, depending on whether the arrangements are service revenue or contractor type revenue.
Service revenues are typically recognized on an equal monthly basis based on the minimum fee to be earned.  The monthly amounts could be adjusted depending on if certain performance milestones are met.
Fee income also includes management fees. These fees arise from contractual agreements with entities in which we have a noncontrolling interest. The management fees are recognized as earned under the respective agreements. Management and other fee income related to partially owned entities are recognized to the extent attributable to the unaffiliated interest.
Contractor type 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 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.
(t) 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.
(u) 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.
(v) Management’s Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates made. On an on-going basis, we evaluate our estimates, including those related to the valuation of our real estate properties, 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.
(w) 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 $1.1  billion, $1.1  billion and $946.0 million and outside the United States were $349.1 million, $228.9 million and $116.7 million for the years ended December 31, 2013, 2012 and 2011, respectively.  We had long-lived assets located in the United States of $5.6 billion, $5.0 billion and $4.3 billion and outside the United States of $2.7 billion, $2.5 billion and $1.0 billion as of December 31, 2013, 2012 and 2011, respectively.
Operating revenues from properties located in the United Kingdom were $197.0 million,  $117.2 million and $43.6 million, or 13.3%, 9.2% and 4.1% of total operating revenues for the years ended December 31, 2013, 2012 and 2011, respectively.  No other foreign country comprised more than 10% of total operating revenues for each of these years.  We had long-lived assets located in the United Kingdom of $1.8 billion, $1.7 billion and $356.0 million, or 21.1%, 22.3% and 6.8% of total long-lived assets as of December 31, 2013, 2012 and 2011, respectively.  No other foreign country comprised more than 10% of total long-lived assets as of each of December 31, 2013, 2012 and 2011.
(x) Recent Accounting Pronouncements
In 2013, the Financial Accounting Standards Board ("FASB") issued new accounting guidance clarifying the accounting for the release of a cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. We do not anticipate that this adoption will have a significant impact on our financial position, results of operations, or cash flows.
In 2013, the FASB issued new accounting guidance clarifying the accounting for obligations resulting from joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. We do not anticipate that this adoption will have a significant impact on our financial position, results of operations, or cash flows.

	(9)    On July 11, 2012, we completed the acquisition of a three-property data center portfolio, totaling approximately 733,000 square feet, located in the greater London area, referred to as the Sentrum Portfolio. The purchase price was £734.6 million (equivalent to approximately $1.1 billion based on the July 11, 2012 exchange rate of £1.00 to $1.55).  In addition, non-cash consideration of £56.5 million (or $87.6 million based on the July 11, 2012 exchange rate of £1.00 to $1.55) was recorded as the expected fair value of contingent consideration as required by prevailing accounting guidance.  There was also a non-cash purchase adjustment related to deferred taxes, which amounted to £68.6 million (or $106.3 million based on the July 11, 2012 exchange rate of £1.00 to $1.55).  The purchase price was paid in cash funded with proceeds from our common stock offering in July 2012 along with borrowings under our global revolving credit facility.
	-10	The Paris Portfolio consists of 1 Rue Jean-Pierre, 127 Rue de Paris and Liet-dit le Christ de Saclay located in the Paris metropolitan area. The Paris Portfolio is considered three properties for our property count.

	Our investment in and share of equity in earnings									$         23,976				$           4,952
	of unconsolidated joint ventures
	Our investment in the 2001 Sixth Avenue unconsolidated joint venture included in our consolidated balance sheet exceeds our equity presented in the joint ventures’ balance sheet since our purchase accounting adjustments are not pushed down to the joint venture.
	In March 2012, we entered into a joint venture with Savvis, Inc., a CenturyLink company. On June 26, 2012, this unconsolidated joint venture acquired a 164,000 square foot property in Hong Kong. The property is located at 33 Chun Choi Street in Hong Kong. As of December 31, 2013, we have contributed approximately $57.4 million to this joint venture.
	PREI ® 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 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 $115.6 million on the sale of the 80% interest in the nine properties during the year ended December 31, 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 the Company’s contributed interest in 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 consolidated income statements.
	The table below presents properties contributed to the PREI® joint venture at their fair value as of the contribution date (dollars in thousands).

	As properties are contributed to the joint venture with PREI®, the net assets are removed from the consolidated financial statements. The table below reflects the carrying values of properties contributed to the joint venture as of the contribution date (in thousands).

	Acquired in place lease value and deferred leasing costs, net		11,459
	Acquired below market leases, net		(483	)
	Net assets contributed	$	193,215
	We amortize the difference between the cost of our investment in the joint venture with PREI® and the book value of the underlying equity into earnings from unconsolidated affilaites on a straight-line basis consistent with the lives of the underlying assets.  The amortization of this difference was approximately $0.1 million for the year ended December 31, 2013.

	of unconsolidated joint ventures
	Our investment in the 2001 Sixth Avenue unconsolidated joint venture included in our consolidated balance sheet exceeds our equity presented in the joint ventures’ balance sheet since our purchase accounting adjustments are not pushed down to the joint venture.
	In March 2012, we entered into a joint venture with Savvis, Inc., a CenturyLink company. On June 26, 2012, this unconsolidated joint venture acquired a 164,000 square foot property in Hong Kong. The property is located at 33 Chun Choi Street in Hong Kong. As of December 31, 2013, we have contributed approximately $57.4 million to this joint venture.
	PREI ® 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 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 $115.6 million on the sale of the 80% interest in the nine properties during the year ended December 31, 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 the Company’s contributed interest in 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 consolidated income statements.
	The table below presents properties contributed to the PREI® joint venture at their fair value as of the contribution date (dollars in thousands).

	Net assets contributed	$	193,215
	We amortize the difference between the cost of our investment in the joint venture with PREI® and the book value of the underlying equity into earnings from unconsolidated affilaites on a straight-line basis consistent with the lives of the underlying assets.  The amortization of this difference was approximately $0.1 million for the year ended December 31, 2013.

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, Japanese yen and Mexican peso denominations. As of December 31, 2013, borrowings under the global revolving credit facility bore interest at an overall blended rate of 1.60% comprised of 1.27% (U.S. dollars), 1.33% (Euros), 3.70% (Australian dollars), 1.31% (Hong Kong dollars), 1.21% (Japanese yen) and 2.32% (Canadian dollars). The interest rates are based on 1-month LIBOR, 1-month EURIBOR, 1-month BBR, 1-month HIBOR, 1-month JPY LIBOR and 1-month CDOR, respectively, plus a margin of 1.10%. The facility also bore a base borrowing rate of 3.35% (USD) which is based on U.S. Prime Rate plus a margin of 0.10%. 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 December 31, 2013, we have capitalized approximately $17.9 million of financing costs related to the global revolving credit facility. As of December 31, 2013, approximately $724.7 million was drawn under this facility and $20.6 million of letters of credit were issued.
The global revolving credit facility contains various restrictive covenants, including limitations on our ability to incur additional indebtedness, make certain investments or merge with another company, and requirements to maintain financial coverage ratios, including with respect to unencumbered assets. In addition, the global revolving credit facility restricts Digital Realty Trust, Inc. from making distributions to its stockholders, or redeeming or otherwise repurchasing shares of its capital stock, after the occurrence and during the continuance of an event of default, except in limited circumstances including as necessary to enable Digital Realty Trust, Inc. to maintain its qualification as a REIT and to minimize the payment of income or excise tax. As of December 31, 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 December 31, 2013, the balance outstanding is approximately $1,021.0 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 December 31, 2013, we were in compliance with all of such covenants. As of December 31, 2013, we have capitalized approximately $8.4 million of financing costs related to the unsecured term loan.
Unsecured Senior Notes
Prudential Shelf Facility
On January 20, 2010, the Operating Partnership closed the sale of $100.0 million aggregate principal amount of its senior unsecured term notes to Prudential Investment Management, Inc. and certain of its affiliates, or, collectively, Prudential, pursuant to a Note Purchase and Private Shelf Agreement, which we refer to as the Prudential shelf facility. The notes were issued in two series referred to as the series D and series E notes. The series D notes have a principal amount of $50.0 million, an interest-only rate of 4.57% per annum and a five-year maturity, and the series E notes have a principal amount of $50.0 million, an interest-only rate of 5.73% per annum and a seven-year maturity. On February 3, 2010, the Operating Partnership closed the sale of an additional $17.0 million aggregate principal amount of its senior unsecured term notes, which we refer to as the series F notes, to Prudential pursuant to the Prudential shelf facility. The series F notes have an interest-only rate of 4.50% per annum and a five-year maturity. We used the proceeds of the series D, series E and series F notes to fund acquisitions, to temporarily repay borrowings under our corporate revolving credit facility, to fund working capital and for general corporate purposes. The sale of the series A ($25.0 million), series B ($33.0 million) and series C ($25.0 million) were completed in July 2008, November 2008 and January 2009, respectively. We may prepay the notes of any series, in whole or in part, at any time at a price equal to the principal amount and accrued interest of the notes being prepaid, plus a make-whole provision. On December 8, 2010, the Operating Partnership and Prudential entered into an amendment to the Note Purchase and Private Shelf Agreement, increasing the capacity of the Prudential shelf facility from $200.0 million to $250.0 million. Our ability to make additional issuances of notes under the Prudential shelf facility expired on July 24, 2011, with $50.0 million remaining unissued under the shelf facility. On July 25, 2011, we repaid the $25.0 million of 7.0% Series A unsecured notes under the Prudential shelf facility at maturity. On November 5, 2013, we repaid the $33.0 million of 9.32% Series B unsecured notes under the Prudential shelf facility at maturity.  As of December 31, 2013 and 2012, there was $142.0 million and $175.0 million of unsecured senior notes outstanding, respectively.
On August 15, 2013, concurrent with the refinancing of the global revolving credit facility, the Operating Partnership and Digital Realty Trust, Inc. and the other subsidiary guarantors set forth therein entered into Amendment No.1 to the Amended and Restated Note Purchase and Private Shelf Agreement with Prudential to conform the restrictive and financial covenants of the original Prudential shelf facility that apply to the outstanding Series B, C, D, E and F Notes under the Prudential shelf facility to those in the global revolving credit facility described above and, subject to the completion of specified conditions, to authorize the potential issuance and sale of up to $50.0 million of additional senior unsecured fixed-rate term notes. The Prudential shelf facility contains restrictive covenants that are identical to those in our global revolving credit facility.

The indenture governing the 2015 Notes contains certain covenants, including (1) a leverage ratio not to exceed 60%, (2) a secured debt leverage ratio not to exceed 40% and (3) an interest coverage ratio of greater than 1.50, and also requires us to maintain total unencumbered assets of not less than 150% of the aggregate principal amount of unsecured debt. At December 31, 2013, we were in compliance with each of these financial covenants.
We entered into a registration rights agreement whereby the Operating Partnership agreed to conduct an offer to exchange the 2015 Notes for a new series of publicly registered notes with substantially identical terms. If the Operating Partnership did not fulfill certain of its obligations under the registration rights agreement, it would have been required to pay liquidated damages to the holders of the 2015 Notes. No separate contingent obligation was recorded as no liquidated damages became probable. We filed a registration statement with the U.S. Securities and Exchange Commission in October 2010 in connection with the exchange offer, which was declared effective in December 2010. We completed the exchange offer on January 19, 2011.
5.875% Notes due 2020
On January 28, 2010, the Operating Partnership issued $500.0 million aggregate principal amount of notes, maturing on February 1, 2020 with an interest rate of 5.875% per annum (the 2020 Notes). The purchase price paid by the initial purchasers was 98.296% of the principal amount. The 2020 Notes are general unsecured senior obligations of the Operating Partnership, rank equally in right of payment with all other senior unsecured indebtedness of the Operating Partnership and are fully and unconditionally guaranteed by Digital Realty Trust, Inc.

Exchangeable Senior Debentures
5.50% Exchangeable Senior Debentures due 2029
On April 20, 2009, the Operating Partnership issued $266.4 million of its 5.50% exchangeable senior debentures due April 15, 2029 (the 2029 Debentures). Costs incurred to issue the 2029 Debentures were approximately $7.8 million. These costs are being amortized over a period of five years, which represents the estimated term of the 2029 Debentures, and are included in deferred financing costs, net in the consolidated balance sheet. The 2029 Debentures are general unsecured senior obligations of the Operating Partnership, rank equally in right of payment with all other senior unsecured indebtedness of the Operating Partnership and are fully and unconditionally guaranteed by Digital Realty Trust, Inc.
Interest is payable on October 15 and April 15 of each year beginning October 15, 2009 until the maturity date of April 15, 2029. The 2029 Debentures bear interest at 5.50% per annum and may be exchanged for shares of Digital Realty Trust, Inc. common stock at an exchange rate that was initially 23.2558 shares per $1,000 principal amount of 2029 Debentures. The exchange rate on the 2029 Debentures is subject to adjustment for certain events, including, but not limited to, certain dividends on Digital Realty Trust, Inc. common stock in excess of $0.33 per share per quarter (the “reference dividend”). Effective December 11, 2013, the exchange rate has been adjusted to 25.5490 shares per $1,000 principal amount of 2029 Debentures as a result of the aggregate dividends in excess of the reference dividend that Digital Realty Trust, Inc. declared and paid on its common stock beginning with the quarter ended September 30, 2013 and through the quarter ended December 31, 2013. Due to the fact that the exchange feature for the 2029 Debentures must be settled in the common stock of Digital Realty Trust, Inc., accounting guidance on convertible debt instruments that requires the principal amount to be settled in cash upon conversion does not apply.

On or after July 15, 2026, the 2026 Debentures would have been exchangeable at the then-applicable exchange rate for cash (up to the principal amount of the 2026 Debentures) and, with respect to any excess exchange value, into cash, shares of Digital Realty Trust, Inc. common stock or a combination of cash and shares of Digital Realty Trust, Inc. common stock. Pursuant to the terms of the Operating Partnership’s agreement of limited partnership, the Operating Partnership would have delivered to Digital Realty Trust, Inc. one common unit for each share of common stock issued upon exchange of the 2026 Debentures. The 2026 Debentures also would have been exchangeable prior to July 15, 2026, but only upon the occurrence of certain specified events, including if the weighted average common stock price exceeded a specified strike price as of the end of a fiscal quarter. Using the treasury method, 370,719 common units contingently issuable upon settlement of the excess exchange value were included as potentially dilutive common units in determining diluted earnings per unit for the year ended December 31, 2011.

	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 consolidated financial statements for the years ended December 31, 2013, 2012 and 2011.
	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 years ended December 31, 2013, 2012 and 2011.
	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 years ended December 31, 2013, 2012 and 2011.   As of December 31, 2013, we had a net deferred tax liability of approximately $146.6 million primarily related to our foreign properties, comprised of a $110.4 million deferred tax asset, net of a $257.0 million deferred tax liability.  The majority of our net deferred tax liability relates to differences between tax 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.

	(d) 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 December 31, 2013 and 2012:
			31-Dec-13					31-Dec-12
			Number of units		Percentage of total			Number of units		Percentage of total
	Digital Realty Trust, Inc.		128,455,350		97.7	%		125,140,783		97.8	%
	Noncontrolling interests consist of:
	Common units held by third parties		1,491,814		1.2			1,515,814		1.2
	Incentive units held by employees and		1,475,207		1.1			1,335,586		1.0
	directors (see note 13)
			131,422,371		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.
	The redemption value of the noncontrolling Operating Partnership common units and the vested incentive units was approximately $124.1 million and $161.5 million based on the closing market price of Digital Realty Trust, Inc. common stock on December 31, 2013 and 2012, respectively.

	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 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.

	(a) Convertible Preferred Units
	5.500% Series D Cumulative Convertible Preferred Units
	On February 6, 2008, the Operating Partnership issued 13,800,000 of its 5.500% series D cumulative convertible preferred units, or the series D preferred units, to the General Partner in conjunction with the General Partner’s issuance of an equivalent number of shares of its 5.500% series D cumulative convertible preferred stock, or the series D preferred stock. Distributions were cumulative on the series D preferred units from the date of original issuance in the amount of $1.375 per unit each year, which was equivalent to 5.500% of the $25.00 liquidation preference per unit. Distributions on the series D preferred units were payable quarterly in arrears. The series D preferred units did not have a stated maturity date and were not subject to any sinking fund. The Operating Partnership was required to redeem the series D units in the event that the General Partner redeemed the series D preferred stock. The General Partner was not allowed to redeem the series D preferred stock except in limited circumstances to preserve the General Partner’s status as a REIT. Upon liquidation, dissolution or winding up, the series D preferred units ranked senior to the common units with respect to the payment of distributions and other amounts and ranked on parity with the Operating Partnership’s series E preferred units and series F preferred units.
	Effective February 26, 2013, the General Partner converted all outstanding shares of its series D preferred stock into shares of its 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 share of the General Partner’s common stock. In connection with this conversion, the Operating Partnership issued 3,054,186 common units to the General Partner upon conversion of 4,802,180 series D cumulative convertible preferred units.  During the years ended December 31, 2013 and 2012, the Operating Partnership issued 3,139,615 and 1,297,675 common units, respectively, to the General Partner upon conversion of 4,936,505 and 2,040,550 series D preferred units in connection with the conversion of 4,936,505 and 2,040,550 shares of the series D preferred stock, respectively.
	(b) Redeemable Preferred Units
	7.000% Series E Cumulative Redeemable Preferred Units
	On September 15, 2011, the Operating Partnership issued 11,500,000 units of its 7.000% series E cumulative redeemable preferred units, or series E 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 7.000% series E cumulative redeemable preferred stock, or the series E preferred stock. Distributions are cumulative on the series E preferred units from the date of original issuance in the amount of $1.750 per unit each year, which is equivalent to 7.000% of the $25.00 liquidation preference per unit. Distributions on the series E preferred units are payable quarterly in arrears. The first distribution paid on the series E preferred units on December 30, 2011 was a pro rata distribution from and including the original issue date to and including December 31, 2011 in the amount of $0.515278 per unit. The series E 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 E units in the event that the General Partner redeems the series E preferred stock. The General Partner is not allowed to redeem the series E preferred stock prior to September 15, 2016 except in limited circumstances to preserve the General Partner’s status as a REIT. On or after September 15, 2016, the General Partner may, at its option, redeem the series E 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 E preferred stock up to but excluding the redemption date. Upon liquidation, dissolution or winding up, the series E preferred units will rank senior to the common units with respect to the payment of distributions and other amounts and rank on parity with the Operating Partnership’s series F and series G preferred units. Except in connection with specified change of control transactions of the General Partner, the series E preferred units are not convertible into or exchangeable for any other property or securities of the Operating Partnership.
	6.625% Series F Cumulative Redeemable Preferred Units

The series F 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 F preferred units in the event that the General Partner redeems the series F preferred stock.  The General Partner is not allowed to redeem the series F preferred stock prior to April 5, 2017 except in limited circumstances to preserve the General Partner’s status as a REIT. On or after April 5, 2017, the General Partner may, at its option, redeem the series F 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 F preferred stock up to but excluding the redemption date. Upon liquidation, dissolution or winding up, the series F preferred units will rank senior to the common units with respect to the payment of distributions and other amounts and rank on parity with the Operating Partnership’s series E and series G preferred units. Except in connection with specified change of control transactions of the General Partner, the series F preferred units are not convertible into or exchangeable for any other property or securities of the Operating Partnership.
	5.875% Series G Cumulative 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 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 and series F 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.
	(c) 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.
	(d) 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 $124.1 million and $161.5 million based on the closing market price of Digital Realty Trust, Inc.’s common stock on December 31, 2013 and 2012, respectively.
	(e) Distributions
	All distributions on our units are at the discretion of Digital Realty Trust, Inc.’s board of directors. We have declared and paid the following distributions on our common and preferred units for the years ended December 31, 2013, 2012 and 2011 (in thousands):

Incentive Plan	'
	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 December 31, 2013, 3,209,240 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 years ended December 31, 2013, 2012 and 2011, certain employees and directors were granted an aggregate of 89,769, 79,237 and 85,910 long-term incentive units, respectively. During the years ended December 31, 2013, 2012 and 2011, certain employees were also granted an aggregate of 95,316, 86,843 and 98,632 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’ Core Funds From Operations, or CFFO, 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 2013, 2012 and 2011 CFFO per diluted share and unit, 75,105 of the 2013 long-term incentive units, net of forfeitures and 78,118 of the 2012 long-term incentive units, net of forfeitures, respectively, and all of the 2011 long-term incentive units, respectively, 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 four years, the current vesting period of the long-term incentive units. 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 years ended December 31, 2013, 2012 and 2011 related to long-term incentive units was approximately $8.9 million, $9.0 million and $8.7 million, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $1.6 million, $1.1 million and $0.8 million for the years ended December 31, 2013, 2012 and 2011, respectively. Unearned compensation representing the unvested portion of the long-term incentive units totaled $12.9 million and $13.3 million as of December 31, 2013 and 2012, respectively. We expect to recognize this unearned compensation over the next 2.5 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 April 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.
	We recognized compensation expense related to the Class C Units subject to the 2007 Grant of $0.5 million and $2.0 million for the years ended December 31, 2012 and 2011, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $0.1 million and $0.3 million for the years ended December 31, 2012 and 2011, respectively.
	(c) Stock Options
	The fair value of each option granted under the Amended and Restated 2004 Incentive Award Plan is estimated on the date of the grant using the Black-Scholes option-pricing model. For the years ended December 31, 2013, 2012 and 2011, no stock options were granted. The fair values are being expensed on a straight-line basis over the vesting period of the options, which ranges from four to five years. All unearned compensation has been recognized as of December 31, 2012.  The expense recorded for the years ended December 31, 2012 and 2011 was approximately $0.2 million and  $0.8 million, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $0.1 million and  $0.2 million for the years ended December 31, 2012 and 2011, respectively.
	The following table summarizes the Amended and Restated 2004 Incentive Award Plan’s stock option activity for the year ended December 31, 2013:

	(d) Restricted Stock
	During the years ended December 31, 2013, 2012 and 2011, certain employees were granted an aggregate of 79,114,  46,617 and 41,220 shares of restricted stock, respectively. During the years ended December 31, 2013, 2012 and 2011, certain employees were also granted an aggregate of 69,995,  52,947 and 50,999 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 CFFO 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 2013, 2012 and 2011 CFFO per diluted share and unit, 50,805 shares of the 2013 restricted stock awards (net of forfeitures) and 49,325 shares of the 2012 restricted stock awards (net of forfeitures) and all of the 2011 restricted stock, respectively, 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 years ended December 31, 2013, 2012 and 2011 related to grants of restricted stock was approximately $2.7 million, $2.9 million and $2.0 million, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $2.5 million, $2.1 million and $1.5 million for the years ended December 31, 2013, 2012 and 2011, respectively. Unearned compensation representing the unvested portion of the restricted stock totaled $8.7 million and $7.4 million as of December 31, 2013 and 2012, respectively. We expect to recognize this unearned compensation over the next 2.8 years on a weighted average basis.
	(e) 401(k) Plan
	We have a 401(k) plan whereby our employees may contribute a portion of their compensation to their respective retirement accounts, in an amount not to exceed the maximum allowed under the Code. The 401(k) Plan complies with Internal Revenue Service requirements as a 401(k) Safe Harbor Plan whereby discretionary contributions made by us are 100% vested. The aggregate cost of our contributions to the 401(k) Plan was approximately $2.4 million, $2.0 million, and $1.5 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Incentive Plan	'
	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 December 31, 2013, 3,209,240 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 years ended December 31, 2013, 2012 and 2011, certain employees and directors were granted an aggregate of 89,769, 79,237 and 85,910 long-term incentive units, respectively. During the years ended December 31, 2013, 2012 and 2011, certain employees were also granted an aggregate of 95,316, 86,843 and 98,632 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’ Core Funds From Operations, or CFFO, 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 2013, 2012 and 2011 CFFO per diluted share and unit, 75,105 of the 2013 long-term incentive units, net of forfeitures and 78,118 of the 2012 long-term incentive units, net of forfeitures, respectively, and all of the 2011 long-term incentive units, respectively, 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 four years, the current vesting period of the long-term incentive units. 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 years ended December 31, 2013, 2012 and 2011 related to long-term incentive units was approximately $8.9 million, $9.0 million and $8.7 million, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $1.6 million, $1.1 million and $0.8 million for the years ended December 31, 2013, 2012 and 2011, respectively. Unearned compensation representing the unvested portion of the long-term incentive units totaled $12.9 million and $13.3 million as of December 31, 2013 and 2012, respectively. We expect to recognize this unearned compensation over the next 2.5 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 April 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.
	We recognized compensation expense related to the Class C Units subject to the 2007 Grant of $0.5 million and $2.0 million for the years ended December 31, 2012 and 2011, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $0.1 million and $0.3 million for the years ended December 31, 2012 and 2011, respectively.
	(c) Stock Options
	The fair value of each option granted under the Amended and Restated 2004 Incentive Award Plan is estimated on the date of the grant using the Black-Scholes option-pricing model. For the years ended December 31, 2013, 2012 and 2011, no stock options were granted. The fair values are being expensed on a straight-line basis over the vesting period of the options, which ranges from four to five years. All unearned compensation has been recognized as of December 31, 2012.  The expense recorded for the years ended December 31, 2012 and 2011 was approximately $0.2 million and  $0.8 million, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $0.1 million and  $0.2 million for the years ended December 31, 2012 and 2011, respectively.

	(d) Restricted Stock
	During the years ended December 31, 2013, 2012 and 2011, certain employees were granted an aggregate of 79,114,  46,617 and 41,220 shares of restricted stock, respectively. During the years ended December 31, 2013, 2012 and 2011, certain employees were also granted an aggregate of 69,995,  52,947 and 50,999 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 CFFO 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 2013, 2012 and 2011 CFFO per diluted share and unit, 50,805 shares of the 2013 restricted stock awards (net of forfeitures) and 49,325 shares of the 2012 restricted stock awards (net of forfeitures) and all of the 2011 restricted stock, respectively, 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 years ended December 31, 2013, 2012 and 2011 related to grants of restricted stock was approximately $2.7 million, $2.9 million and $2.0 million, respectively. We capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $2.5 million, $2.1 million and $1.5 million for the years ended December 31, 2013, 2012 and 2011, respectively. Unearned compensation representing the unvested portion of the restricted stock totaled $8.7 million and $7.4 million as of December 31, 2013 and 2012, respectively. We expect to recognize this unearned compensation over the next 2.8 years on a weighted average basis.
	(e) 401(k) Plan
	We have a 401(k) plan whereby our employees may contribute a portion of their compensation to their respective retirement accounts, in an amount not to exceed the maximum allowed under the Code. The 401(k) Plan complies with Internal Revenue Service requirements as a 401(k) Safe Harbor Plan whereby discretionary contributions made by us are 100% vested. The aggregate cost of our contributions to the 401(k) Plan was approximately $2.4 million, $2.0 million, and $1.5 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Derivative_Instruments

Derivative Instruments	12 Months Ended

Derivative Instruments	'
	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, 2013, 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 December 31, 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 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 2013, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. The fair value of these derivatives was $0.1 million and ($8.7) million at December 31, 2013 and December 31, 2012, respectively.

Derivative Instruments	'
	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, 2013, 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 December 31, 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 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 2013, such derivatives were used to hedge the variable cash flows associated with existing variable-rate debt. The fair value of these derivatives was $0.1 million and ($8.7) million at December 31, 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 years ended December 31, 2013, 2012 and 2011, 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 December 31, 2013, we estimate that an additional $3.1 million will be reclassified as an increase to interest expense during the year ending December 31, 2014, when the hedged forecasted transactions impact earnings.

	We have ground leases on Paul van Vlissingenstraat 16 that expires in 2054, Chemin de l’Epinglier 2 that expires in 2074, Clonshaugh Industrial Estate I and II that expires in 2981, Manchester Technopark that expires in 2125, 29A International Business Park that expires in 2038, Gyroscoopweg 2E-2F, which has a continuous ground lease and will be adjusted on January 1, 2042, and Naritaweg 52, which has a continuous ground lease. In late 2011, we executed a lease for a new location for our headquarters, which began in May 2012, with a lease term of 12 years with an option to extend the lease for an additional five years. We also have operating leases at 111 8th Avenue (2nd and 6th floors), 8100 Boone Boulevard, 111 8th Avenue (3rd and 7th floors) and 410 Commerce Boulevard, which expire in June 2024, September 2017, February 2022 and December 2026, respectively. The lease at 111 8th Avenue (2nd and 6th floors) has an option to extend the lease until June 2034 and the lease at 111 8th Avenue (3rd and 7th floors) has an option to extend the lease until February 2032. The leases at 8100 Boone Boulevard and 410 Commerce Boulevard have no extension options.
	We have a fully prepaid ground lease on 2055 E. Technology Circle that expires in 2083. We have a fully prepaid ground lease on Cateringweg 5 that expires in 2059. The ground lease at Naritaweg 52 has been prepaid through December 2036.
	Rental expense for these leases was approximately $23.1 million, $10.2 million, and $8.5 million for the years ended December 31, 2013, 2012 and 2011 respectively. In 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, $7.5 million of this amount related to prior years. This adjustment was deemed to be immaterial to both the current year and prior year financial statements taken as a whole.
	The minimum commitment under these leases, excluding the fully prepaid ground leases, as of December 31, 2013 was as follows (in thousands):
	2014	$     13,377
	2015	15,381
	2016	14,798

	(b) 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 December 31, 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 December 31, 2013. The maximum amount that could be earned by the seller is $50.0 million SGD (or approximately $39.6 million based on the exchange rate as of December 31, 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 year ended December 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 material 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 December 31, 2013, the fair value of the contingent consideration for Sentrum was £39.2 million (or approximately $64.9 million based on the exchange rate as of December 31, 2013) and is currently accrued in accounts payable and other accrued expenses in the consolidated balance sheet. During the year ended December 31, 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 $1.8 million and $1.1 million for the years ended December 31, 2013 and 2012, 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.
	(c) 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 December 31, 2013, we had open commitments related to construction contracts of approximately $202.1 million.
	(d) Legal Proceedings
	Although the Company is involved in legal proceedings arising in the ordinary course of business, as of December 31, 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.

Principles Of Consolidation And Basis Of Presentation	'
	(a) Principles of Consolidation and Basis of Presentation
	The accompanying 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 notes to the 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 few differences between the Company and the Operating Partnership, which are reflected in these 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 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 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 consolidated financial statements and as noncontrolling interests in operating partnership within equity in Digital Realty Trust, Inc.’s 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 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 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:
		•		consolidated face financial statements; and
		•		the following notes to the consolidated financial statements:
		•		Debt of the Company and Debt of the Operating Partnership;
		•		Income per Share and Income per Unit;
		•		Equity and Accumulated Other Comprehensive Income (Loss), Net of the Company and Capital and Accumulated Other Comprehensive Income (Loss) of the Operating Partnership; and
		•		Quarterly Financial Information.
	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.
Cash Equivalents	'
	(b) Cash Equivalents
	For the purpose of the consolidated statements of cash flows, we consider short-term investments with original maturities of 90 days or less to be cash equivalents. As of December 31, 2013 and 2012, cash equivalents consist of investments in money market instruments.
Investments In Real Estate	'
	(c) Investments in Real Estate
	Investments in real estate are stated at cost, less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives as follows:
	Acquired ground leases		Terms of the related lease
	Buildings and improvements		5-39 years
	Tenant improvements		Shorter of the estimated useful lives or the terms of the related leases
	Improvements and replacements are capitalized when they extend the useful life, increase capacity, or improve the efficiency of the asset. Repairs and maintenance are charged to expense as incurred.
Investment In Unconsolidated Joint Ventures	'
	(d) Investment in Unconsolidated Joint Ventures
	The Company’s investment in unconsolidated joint ventures is accounted for using the equity method, whereby the investment is increased for capital contributed and our share of the joint ventures’ net income and decreased by distributions we receive and our share of any losses of the joint ventures.
	We amortize the difference between the cost of our investments in unconsolidated joint ventures and the book value of the underlying equity into equity in earnings from unconsolidated affiliates on a straight-line basis consistent with the lives of the underlying assets.
Impairment Of Long-Lived Assets	'
	(e) Impairment of Long-Lived Assets
	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 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. Management believes no impairment in the net carrying value of our investments in real estate has occurred.
Purchase Accounting For Acquisition Of Investments In Real Estate	'
	(f) Purchase Accounting for Acquisition of Investments in Real Estate
	Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired from third parties. In accordance with current accounting guidance,  the fair value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and tenant improvements, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases, value of tenant relationships and acquired ground leases, based in each case on their fair values. Loan premiums, in the case of above market rate loans, or loan discounts, in the case of below market loans, are recorded based on the fair value of any loans assumed in connection with acquiring the real estate.
	The fair values of the tangible assets of an acquired property are determined based on comparable land sales for land and replacement costs adjusted for physical and market obsolescence for the improvements. The fair values of the tangible assets of an acquired property are also determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land, building and tenant improvements based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a property based on assumptions that a market participant would use, which is similar to methods used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related costs.
	In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) estimated fair market lease rates from the perspective of a market participant for the corresponding in-place leases, measured, for above-market leases, over a period equal to the remaining non-cancelable term of the lease and, for below-market leases, over a period equal to the initial term plus any below market fixed rate renewal periods. The leases we have acquired do not currently include any below market fixed rate renewal periods. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. The capitalized below-market lease values, also referred to as acquired lease obligations, are amortized as an increase to rental income over the initial terms of the respective leases and any below market fixed rate renewal periods.
	In addition to the intangible value for above market leases and the intangible negative value for below market leases, there is intangible value related to having tenants leasing space in the purchased property, which is referred to as in-place lease value and tenant relationship value. Such value results primarily from the buyer of a leased property avoiding the costs associated with leasing the property and also avoiding rent losses and unreimbursed operating expenses during the lease up period. The estimated avoided costs and avoided revenue losses are calculated and this aggregate value is allocated between in-place lease value and tenant relationships based on management’s evaluation of the specific characteristics of each tenant’s lease; however, the value of tenant relationships has not been separated from in-place lease value for our real estate because such value and its consequence to amortization expense is immaterial for these particular acquisitions. The value of in-place leases exclusive of the value of above-market in-place leases is amortized to expense over the estimated term (including renewal and extension assumptions) of the respective leases. If a lease were to be terminated prior to its estimated term, all unamortized amounts relating to that lease would be written off.
Capitalization Of Costs	'
	(g) 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.
	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. During the year ended December 31, 2013, the total incremental amounts capitalized that would have been recorded as rental property operating expense under our previous policies was approximately $9.5 million.
	During the years ended December 31, 2013, 2012 and 2011, we capitalized interest of approximately $26.3 million, $21.5 million and $17.9 million, respectively. During the years ended December 31, 2013, 2012 and 2011, we capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $37.6 million, $31.6 million and $24.7 million, respectively. Cash flows from capitalized leasing costs of $57.5 million, $40.1 million and $28.2 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 years ended December 31, 2013, 2012 and 2011, respectively.
Deferred Leasing Costs	'
	(h) Deferred Leasing Costs
	Leasing commissions and other direct and indirect costs associated with the acquisition of tenants are capitalized and amortized on a straight line basis over the terms of the related leases.
Foreign Currency Translation	'
	(i) Foreign Currency Translation
	Assets and liabilities of our subsidiaries outside the United States with non-U.S. dollar functional currencies are translated into U.S. dollars using exchange rates as of the balance sheet dates. Income and expenses are translated using the average exchange rates for the reporting period. Foreign currency translation adjustments are recorded as a component of other comprehensive income.
Deferred Financing Costs	'
	(j) Deferred Financing Costs
	Loan fees and costs are capitalized and amortized over the life of the related loans on a straight-line basis, which approximates the effective interest method. Such amortization is included as a component of interest expense.
Restricted Cash	'
	(k) Restricted Cash
	Restricted cash consists of deposits for real estate taxes and insurance and other amounts as required by our loan agreements including funds for leasing costs and improvements related to unoccupied space.
Offering Costs	'
	(l) Offering Costs
	Underwriting commissions and other offering costs are reflected as a reduction in additional paid-in capital, or in the case of preferred stock, as a reduction of the carrying value of preferred stock.
Share Based Compensation	'
	(m) 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.
Accounting For Derivative Instruments And Hedging Activities	'
	(n) Accounting for Derivative Instruments and Hedging Activities
	We account for our derivative instruments and hedging activities in accordance with the accounting standard for derivative and hedging activities. The accounting standard requires us to measure every derivative instrument (including certain derivative instruments embedded in other contracts) at fair value and record them in the balance sheet as either an asset or liability.
	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. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the years ended December 31, 2013, 2012 and 2011, respectively, there were no ineffective portions to our interest rate swaps.
	We actively manage our ratio of fixed-to-floating rate debt. To manage our fixed and floating rate debt in a cost-effective manner, we, from time to time, enter into interest rate swap agreements as cash flow hedges, under which we agree to exchange various combinations of fixed and/or variable interest rates based on agreed upon notional amounts. We do not enter into derivative instruments for trading purposes.
Income Taxes	'
	(o) 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 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 U.S. 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 December 31, 2013 and 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 consolidated statements of operations. For the years ended December 31, 2013, 2012 and 2011, we had no such interest or penalties. The tax year 2010 and thereafter 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.
Presentation Of Transactional-Based Taxes	'
	(p) 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.
Revenue Recognition	'
	(q) Revenue Recognition
	All leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the terms of the leases. The excess of rents recognized over amounts contractually due pursuant to the underlying leases is included in deferred rent in the accompanying consolidated balance sheets and contractually due but unpaid rents are included in accounts and other receivables.
	Tenant reimbursements for real estate taxes, common area maintenance, and other recoverable costs are recognized in the period that the expenses are incurred. Lease termination fees, which are included in other income in the accompanying statements of operations, are recognized over the new remaining term of the lease, effective as of the date the lease modification is finalized, and assuming collection is probable.
	A provision for loss is made if the collection of the receivable balances related to contractual rent, rent recorded on a straight-line basis, tenant reimbursements and lease termination fees are considered to be doubtful.
Asset Retirement Obligations	'
	(r) 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 December 31, 2013 and December 31, 2012, the amount included in accounts payable and other accrued liabilities on our consolidated balance sheets was approximately $1.7 million and $1.7 million, respectively.
Construction Management Revenue	'
	(s) Fee Income
	Occasionally, customers engage the company for certain consulting services.  The nature of these services historically involves property management, construction management, and assistance with financing.  The proper revenue recognition of these services can be different, depending on whether the arrangements are service revenue or contractor type revenue.
	Service revenues are typically recognized on an equal monthly basis based on the minimum fee to be earned.  The monthly amounts could be adjusted depending on if certain performance milestones are met.
	Fee income also includes management fees. These fees arise from contractual agreements with entities in which we have a noncontrolling interest. The management fees are recognized as earned under the respective agreements. Management and other fee income related to partially owned entities are recognized to the extent attributable to the unaffiliated interest.
	Contractor type 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 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.
Assets And Liabilities Measured At Fair Value	'
	(t) 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.
Transactions Expense	'
	(u) 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.
Management's Estimates	'
	(v) Management’s Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates made. On an on-going basis, we evaluate our estimates, including those related to the valuation of our real estate properties, 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.
Segment And Geographic Information	'
	(w) 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 $1.1  billion, $1.1  billion and $946.0 million and outside the United States were $349.1 million, $228.9 million and $116.7 million for the years ended December 31, 2013, 2012 and 2011, respectively.  We had long-lived assets located in the United States of $5.6 billion, $5.0 billion and $4.3 billion and outside the United States of $2.7 billion, $2.5 billion and $1.0 billion as of December 31, 2013, 2012 and 2011, respectively.
	Operating revenues from properties located in the United Kingdom were $197.0 million,  $117.2 million and $43.6 million, or 13.3%, 9.2% and 4.1% of total operating revenues for the years ended December 31, 2013, 2012 and 2011, respectively.  No other foreign country comprised more than 10% of total operating revenues for each of these years.  We had long-lived assets located in the United Kingdom of $1.8 billion, $1.7 billion and $356.0 million, or 21.1%, 22.3% and 6.8% of total long-lived assets as of December 31, 2013, 2012 and 2011, respectively.  No other foreign country comprised more than 10% of total long-lived assets as of each of December 31, 2013, 2012 and 2011.
Recent Accounting Pronouncements	'
	(x) Recent Accounting Pronouncements
	In 2013, the Financial Accounting Standards Board ("FASB") issued new accounting guidance clarifying the accounting for the release of a cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. We do not anticipate that this adoption will have a significant impact on our financial position, results of operations, or cash flows.

Digital Realty Trust, L.P. [Member]	'
Principles Of Consolidation And Basis Of Presentation	'
	(a) Principles of Consolidation and Basis of Presentation
	The accompanying 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 notes to the 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 few differences between the Company and the Operating Partnership, which are reflected in these 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 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 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 consolidated financial statements and as noncontrolling interests in operating partnership within equity in Digital Realty Trust, Inc.’s 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 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 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:
		•		consolidated face financial statements; and
		•		the following notes to the consolidated financial statements:
		•		Debt of the Company and Debt of the Operating Partnership;
		•		Income per Share and Income per Unit;
		•		Equity and Accumulated Other Comprehensive Income (Loss), Net of the Company and Capital and Accumulated Other Comprehensive Income (Loss) of the Operating Partnership; and
		•		Quarterly Financial Information.
	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.
Cash Equivalents	'
	(b) Cash Equivalents
	For the purpose of the consolidated statements of cash flows, we consider short-term investments with original maturities of 90 days or less to be cash equivalents. As of December 31, 2013 and 2012, cash equivalents consist of investments in money market instruments.
Investments In Real Estate	'
	(c) Investments in Real Estate
	Investments in real estate are stated at cost, less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization are recorded on a straight-line basis over the estimated useful lives as follows:
	Acquired ground leases		Terms of the related lease
	Buildings and improvements		5-39 years
	Tenant improvements		Shorter of the estimated useful lives or the terms of the related leases
	Improvements and replacements are capitalized when they extend the useful life, increase capacity, or improve the efficiency of the asset. Repairs and maintenance are charged to expense as incurred.
Investment In Unconsolidated Joint Ventures	'
	(d) Investment in Unconsolidated Joint Ventures
	The Company’s investment in unconsolidated joint ventures is accounted for using the equity method, whereby the investment is increased for capital contributed and our share of the joint ventures’ net income and decreased by distributions we receive and our share of any losses of the joint ventures.
	We amortize the difference between the cost of our investments in unconsolidated joint ventures and the book value of the underlying equity into equity in earnings from unconsolidated affiliates on a straight-line basis consistent with the lives of the underlying assets.
Impairment Of Long-Lived Assets	'
	(e) Impairment of Long-Lived Assets
	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 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. Management believes no impairment in the net carrying value of our investments in real estate has occurred.
Purchase Accounting For Acquisition Of Investments In Real Estate	'
	(f) Purchase Accounting for Acquisition of Investments in Real Estate
	Purchase accounting is applied to the assets and liabilities related to all real estate investments acquired from third parties. In accordance with current accounting guidance,  the fair value of the real estate acquired is allocated to the acquired tangible assets, consisting primarily of land, building and tenant improvements, and identified intangible assets and liabilities, consisting of the value of above-market and below-market leases, other value of in-place leases, value of tenant relationships and acquired ground leases, based in each case on their fair values. Loan premiums, in the case of above market rate loans, or loan discounts, in the case of below market loans, are recorded based on the fair value of any loans assumed in connection with acquiring the real estate.
	The fair values of the tangible assets of an acquired property are determined based on comparable land sales for land and replacement costs adjusted for physical and market obsolescence for the improvements. The fair values of the tangible assets of an acquired property are also determined by valuing the property as if it were vacant, and the “as-if-vacant” value is then allocated to land, building and tenant improvements based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a property based on assumptions that a market participant would use, which is similar to methods used by independent appraisers. Factors considered by management in performing these analyses include an estimate of carrying costs during the expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and other operating expenses and estimates of lost rental revenue during the expected lease-up periods based on current market demand. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related costs.
	In allocating the fair value of the identified intangible assets and liabilities of an acquired property, above-market and below-market in-place lease values are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) estimated fair market lease rates from the perspective of a market participant for the corresponding in-place leases, measured, for above-market leases, over a period equal to the remaining non-cancelable term of the lease and, for below-market leases, over a period equal to the initial term plus any below market fixed rate renewal periods. The leases we have acquired do not currently include any below market fixed rate renewal periods. The capitalized above-market lease values are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. The capitalized below-market lease values, also referred to as acquired lease obligations, are amortized as an increase to rental income over the initial terms of the respective leases and any below market fixed rate renewal periods.
	In addition to the intangible value for above market leases and the intangible negative value for below market leases, there is intangible value related to having tenants leasing space in the purchased property, which is referred to as in-place lease value and tenant relationship value. Such value results primarily from the buyer of a leased property avoiding the costs associated with leasing the property and also avoiding rent losses and unreimbursed operating expenses during the lease up period. The estimated avoided costs and avoided revenue losses are calculated and this aggregate value is allocated between in-place lease value and tenant relationships based on management’s evaluation of the specific characteristics of each tenant’s lease; however, the value of tenant relationships has not been separated from in-place lease value for our real estate because such value and its consequence to amortization expense is immaterial for these particular acquisitions. The value of in-place leases exclusive of the value of above-market in-place leases is amortized to expense over the estimated term (including renewal and extension assumptions) of the respective leases. If a lease were to be terminated prior to its estimated term, all unamortized amounts relating to that lease would be written off.
Capitalization Of Costs	'
	(g) 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.
	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. During the year ended December 31, 2013, the total incremental amounts capitalized that would have been recorded as rental property operating expense under our previous policies was approximately $9.5 million.
	During the years ended December 31, 2013, 2012 and 2011, we capitalized interest of approximately $26.3 million, $21.5 million and $17.9 million, respectively. During the years ended December 31, 2013, 2012 and 2011, we capitalized amounts relating to compensation expense of employees direct and incremental to construction and successful leasing activities of approximately $37.6 million, $31.6 million and $24.7 million, respectively. Cash flows from capitalized leasing costs of $57.5 million, $40.1 million and $28.2 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 years ended December 31, 2013, 2012 and 2011, respectively.
Deferred Leasing Costs	'
	(h) Deferred Leasing Costs
	Leasing commissions and other direct and indirect costs associated with the acquisition of tenants are capitalized and amortized on a straight line basis over the terms of the related leases.
Foreign Currency Translation	'
	(i) Foreign Currency Translation
	Assets and liabilities of our subsidiaries outside the United States with non-U.S. dollar functional currencies are translated into U.S. dollars using exchange rates as of the balance sheet dates. Income and expenses are translated using the average exchange rates for the reporting period. Foreign currency translation adjustments are recorded as a component of other comprehensive income.
Deferred Financing Costs	'
	(j) Deferred Financing Costs
	Loan fees and costs are capitalized and amortized over the life of the related loans on a straight-line basis, which approximates the effective interest method. Such amortization is included as a component of interest expense.
Restricted Cash	'
	(k) Restricted Cash
	Restricted cash consists of deposits for real estate taxes and insurance and other amounts as required by our loan agreements including funds for leasing costs and improvements related to unoccupied space.
Offering Costs	'
	(l) Offering Costs
	Underwriting commissions and other offering costs are reflected as a reduction in additional paid-in capital, or in the case of preferred stock, as a reduction of the carrying value of preferred stock.
Share Based Compensation	'
	(m) 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.
Accounting For Derivative Instruments And Hedging Activities	'
	(n) Accounting for Derivative Instruments and Hedging Activities
	We account for our derivative instruments and hedging activities in accordance with the accounting standard for derivative and hedging activities. The accounting standard requires us to measure every derivative instrument (including certain derivative instruments embedded in other contracts) at fair value and record them in the balance sheet as either an asset or liability.
	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. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the years ended December 31, 2013, 2012 and 2011, respectively, there were no ineffective portions to our interest rate swaps.
	We actively manage our ratio of fixed-to-floating rate debt. To manage our fixed and floating rate debt in a cost-effective manner, we, from time to time, enter into interest rate swap agreements as cash flow hedges, under which we agree to exchange various combinations of fixed and/or variable interest rates based on agreed upon notional amounts. We do not enter into derivative instruments for trading purposes.
Income Taxes	'
	(o) 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 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 U.S. 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 December 31, 2013 and 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 consolidated statements of operations. For the years ended December 31, 2013, 2012 and 2011, we had no such interest or penalties. The tax year 2010 and thereafter 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.
Presentation Of Transactional-Based Taxes	'
	(p) 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.
Revenue Recognition	'
	(q) Revenue Recognition
	All leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the terms of the leases. The excess of rents recognized over amounts contractually due pursuant to the underlying leases is included in deferred rent in the accompanying consolidated balance sheets and contractually due but unpaid rents are included in accounts and other receivables.
	Tenant reimbursements for real estate taxes, common area maintenance, and other recoverable costs are recognized in the period that the expenses are incurred. Lease termination fees, which are included in other income in the accompanying statements of operations, are recognized over the new remaining term of the lease, effective as of the date the lease modification is finalized, and assuming collection is probable.
	A provision for loss is made if the collection of the receivable balances related to contractual rent, rent recorded on a straight-line basis, tenant reimbursements and lease termination fees are considered to be doubtful.
Asset Retirement Obligations	'
	(r) 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 December 31, 2013 and December 31, 2012, the amount included in accounts payable and other accrued liabilities on our consolidated balance sheets was approximately $1.7 million and $1.7 million, respectively.
Construction Management Revenue	'
	(s) Fee Income
	Occasionally, customers engage the company for certain consulting services.  The nature of these services historically involves property management, construction management, and assistance with financing.  The proper revenue recognition of these services can be different, depending on whether the arrangements are service revenue or contractor type revenue.
	Service revenues are typically recognized on an equal monthly basis based on the minimum fee to be earned.  The monthly amounts could be adjusted depending on if certain performance milestones are met.
	Fee income also includes management fees. These fees arise from contractual agreements with entities in which we have a noncontrolling interest. The management fees are recognized as earned under the respective agreements. Management and other fee income related to partially owned entities are recognized to the extent attributable to the unaffiliated interest.
	Contractor type 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 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.
Assets And Liabilities Measured At Fair Value	'
	(t) 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.
Transactions Expense	'
	(u) 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.
Management's Estimates	'
	(v) Management’s Estimates
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates made. On an on-going basis, we evaluate our estimates, including those related to the valuation of our real estate properties, 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.
Segment And Geographic Information	'
	(w) 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 $1.1  billion, $1.1  billion and $946.0 million and outside the United States were $349.1 million, $228.9 million and $116.7 million for the years ended December 31, 2013, 2012 and 2011, respectively.  We had long-lived assets located in the United States of $5.6 billion, $5.0 billion and $4.3 billion and outside the United States of $2.7 billion, $2.5 billion and $1.0 billion as of December 31, 2013, 2012 and 2011, respectively.
	Operating revenues from properties located in the United Kingdom were $197.0 million,  $117.2 million and $43.6 million, or 13.3%, 9.2% and 4.1% of total operating revenues for the years ended December 31, 2013, 2012 and 2011, respectively.  No other foreign country comprised more than 10% of total operating revenues for each of these years.  We had long-lived assets located in the United Kingdom of $1.8 billion, $1.7 billion and $356.0 million, or 21.1%, 22.3% and 6.8% of total long-lived assets as of December 31, 2013, 2012 and 2011, respectively.  No other foreign country comprised more than 10% of total long-lived assets as of each of December 31, 2013, 2012 and 2011.
Recent Accounting Pronouncements	'
	(x) Recent Accounting Pronouncements
	In 2013, the Financial Accounting Standards Board ("FASB") issued new accounting guidance clarifying the accounting for the release of a cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2013. We do not anticipate that this adoption will have a significant impact on our financial position, results of operations, or cash flows.

Acquisition of 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 the final payment of $1.4 million made in December 2013.

[4]

In connection with the acquisition, we assumed a $26.4 million secured mortgage loan.

On JulyB 11, 2012, we completed the acquisition of a three-property data center portfolio, totaling approximately 733,000 square feet, located in the greater London area, referred to as the Sentrum Portfolio. The purchase price was £734.6B million (equivalent to approximately $1.1 billion based on the JulyB 11, 2012 exchange rate of £1.00 to $1.55). In addition, non-cash consideration of £56.5 million (or $87.6 million based on the July 11, 2012 exchange rate of £1.00 to $1.55) was recorded as the expected fair value of contingent consideration as required by prevailing accounting guidance. There was also a non-cash purchase adjustment related to deferred taxes, which amounted to £68.6 million (or $106.3 million based on the July 11, 2012 exchange rate of £1.00 to $1.55). The purchase price was paid in cash funded with proceeds from our common stock offering in July 2012 along with borrowings under our global revolving credit facility.

[9]

The Paris Portfolio consists of 1 Rue Jean-Pierre, 127 Rue de Paris and Liet-dit le Christ de Saclay located in the Paris metropolitan area. The Paris Portfolio is considered three properties for our property count.

Purchase prices are all in U.S. dollars and exclude capitalized closing costs on land acquisitions. Purchase prices for acquisitions outside the United States are based on the exchange rate at the date of acquisition.
