Except for net proceeds from public equity issuances by the Parent, which are generally contributed to the OP in exchange for partnership units, the OP generally generates the capital required by the Company’s business primarily through the OP’s operations, by the OP’s or its affiliates’ direct or indirect incurrence of indebtedness or through the issuance of partnership units. Accounting Principles and Basis of Presentation. ​ Management Estimates and Assumptions . U.S. GAAP requires us to make estimates and assumptions that affect reported amounts of revenue and expenses during the reporting period, reported amounts for assets and liabilities as of the date of the financial statements, and disclosures of contingent assets and liabilities as of the date of the financial statements. Although we believe the estimates and assumptions we made are reasonable and appropriate, as discussed in the applicable sections throughout the consolidated financial statements, different assumptions and estimates could materially impact our reported results. Actual results and outcomes may differ from our assumptions.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Consolidation We consolidate all entities that are wholly owned as well as all partially-owned entities that we control. In addition, we consolidate any variable interest entities (“VIEs”) for which we are the primary beneficiary. We evaluate whether or not an entity is a VIE (and we are the primary beneficiary) through consideration of substantive terms in the arrangement to identify which enterprise has the power to direct the activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses/receive benefits from the entity. For entities that do not meet the definition of VIEs, we first consider if we are the general partner or a limited partner (or the equivalent in investments not structured as partnerships). We consolidate entities in which we are the general partner and the limited partners do not have rights that would preclude control. For entities in which we are the general partner, but the limited partners hold substantive participating or kick-out rights that prohibit our ability to control the entity, we apply the equity method of accounting since, as the general partner, we have the ability to exercise significant influence over the operating and financial policies of the entities. For entities in which we are a limited partner, or that are not structured similar to a partnership, we consider factors such as ownership interest, voting control, authority to make decisions and contractual and substantive participating rights of the partners. When factors indicate we have a controlling financial interest in an entity, we consolidate the entity. Foreign Operations and Foreign Currencies. The functional currency of each of our consolidated subsidiaries and unconsolidated entities operating in other countries is the principal currency in which each entity’s assets, liabilities, income and expenses are denominated, which may be different from the local currency of incorporation or the currency with which the entities conduct their operations. The primary functional currencies impacting our business include the Euro, Japanese yen, British pound sterling, Singapore dollar, South African rand and Brazilian real. For our consolidated subsidiaries whose functional currency is not the U.S. dollar, we translate financial statements into U.S. dollars at the time we consolidate these subsidiaries’ financial statements. Generally, assets and liabilities are translated at the exchange rate in effect at the balance sheet date. Certain balance sheet items, such as equity and capital-related accounts are reflected at historical exchange rates. Income statement accounts are generally translated at the average exchange rates for the reporting periods. We and certain of our consolidated subsidiaries have intercompany and third-party debt that is not denominated in the functional currency of the entities. When debt is denominated in a currency other than the functional currency of an entity, a gain or loss can result. The associated adjustment is reflected in other (expenses) income, net, in the consolidated income statements, unless it is intercompany debt that is deemed to be long-term in nature or third-party debt that has been designated as a nonderivative net investment hedge – in which case the associated adjustments are reflected as a cumulative translation adjustments as a component of other comprehensive income. In the statement of cash flows, cash flows denominated in foreign currencies are translated using the exchange rates in effect at the time of the respective cash flows or at average exchange rates for the period, depending on the nature of the cash flow items. Acquisition Accounting . We evaluate whether or not substantially all of the value of acquired assets is concentrated in a single identifiable asset or group of identifiable assets to determine whether a transaction is accounted for as an asset acquisition or a business combination. For asset acquisitions: (1) transaction costs are included in the total costs of the acquisition and are allocated on a pro-rata basis to the carrying value of the assets and liabilities acquired, (2) real estate assets acquired are measured based on their cost or total consideration exchanged with any excess consideration or bargain purchase amount allocated to real estate properties and their associated intangibles such as above and below-market leases, in-place leases, acquired ground leases, and customer relationship value and (3) all other assets and liabilities assumed, including any debt, are recorded at fair value. For business combinations: (1) transaction costs are expensed as incurred, (2) all acquired tangible and identifiable intangible assets are recognized at fair value, (3) the amount of any purchase consideration that exceeds the fair value of the tangible and identifiable intangible assets acquired is recognized as goodwill, and (4) to the extent the purchase consideration is less than the fair value of the tangible and identifiable intangible assets acquired, a gain on bargain purchase is recognized. When we obtain control of an unconsolidated entity that we previously held as an equity method investment and the acquisition qualifies as a business combination, we remeasure our previously held interest in the unconsolidated entity at its acquisition-date fair value, derecognize the book value associated with that interest, and recognize any resulting gain or loss in earnings. We allocate purchase price primarily using Level 2 and Level 3 inputs (further defined in Fair Value Measurements) as follows: Real Estate Lease Intangibles. ● Above and below market leases: We use a discounted cash flow approach to determine the estimated present value of any difference between contractual rents for acquired in-place leases as compared to current market rents. If rents on acquired in-place leases are higher than current market rents, we record an intangible asset for the favorable rents. If rents on acquired in-place leases are lower than current market rents, we record a liability for the unfavorable rents. Favorable rent assets are amortized as a reduction to rental income over the remaining non-cancelable term of the lease. Unfavorable rent liabilities are amortized as an increase to rental income over the initial lease term plus any below-market fixed rate renewal periods. ● In-place lease value: Since the as-if-vacant model is used to determine the value of acquired operating properties, the value of such properties does not include the value associated with having existing tenants who are leasing space in the purchased properties. Having in-place tenants allows buyers to avoid costs associated with leasing the property as well as any rent losses and unreimbursed operating expenses during the lease-up period. An asset for such benefits is recorded separately as in-place lease value. In-place lease value is determined based on estimated carrying costs during hypothetical expected lease-up periods as well as costs to execute similar leases. We determine expected carrying costs and costs to execute similar leases in the same manner as described in the previous discussion of the valuation of operating properties using the as-if-vacant model. The value of in-place leases is amortized to expense over the remaining initial terms of the respective leases. ● Customer relationship value: In some transactions, customers acquired are expected to generate recurring revenues beyond existing in-place lease terms. We utilize the multi-period excess earnings method to determine value customer relationship value, if any. Key factors reflected in this approach include: (1) projected revenue growth from existing customers, (2) historical customer lease renewals and attrition rates, (3) rental renewal probabilities and related market terms, (4) estimated operating costs, and (5) discount rate. Customer relationship value is amortized to expense ratably over the anticipated life of substantially all of the acquired customer relationships that are expected to generate excess earnings. Debt. Noncontrolling interests. Other acquired assets and liabilities. Fair Value Measurements. Fair value is intended to reflect the price that would be received for the sale of an asset or paid for the transfer of a liability in an orderly transaction between market participants at the measurement date (the exit price). We estimate fair value using available market information and valuation methods we believe to be appropriate for these purposes. Given the significant amount of judgement and subjectivity involved in the determination of fair value, estimated fair value is not necessarily indicative of amounts that would be realized on disposition. There are three levels in the fair value hierarchy under US GAAP, which are: ● Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that an entity can access at the measurement date. ● Level 2 – Inputs that are directly or indirectly observable for the associated asset or liability, but which do not qualify as Level 1 inputs. ● Level 3 – Unobservable inputs for the asset or liability. In instances where inputs from multiple different levels of the fair value hierarchy are used to determine fair value, the lowest level input that is significant is used to determine the fair-value measurement in its entirety. Our assessment of the significance of a particular input to a fair-value measurement requires judgment and considers factors specific to the asset or liability. We utilize fair value measurements on a recurring basis to determine the fair value of: marketable equity securities, share-based compensation awards, derivative instruments, and outstanding debt. Such measurements are also regularly utilized in assessing whether or not impairments may exist on intangible assets (including goodwill). In addition, we utilize fair value measurements on a non-recurring basis to determine the fair value associated with assets held for sale, acquisitions of assets, and acquisitions of businesses. ​ Investments in Unconsolidated Entities. Investments in unconsolidated entities as reflected on the consolidated balance sheets includes all investments accounted for using the equity method. We use the equity method to account for these investments, because we have the ability to exercise significant influence over their operating and financial policies, but do not control them. Equity method investments are initially recognized at our cost. Transaction costs related to the formation of equity method investments are also capitalized. We subsequently adjust these balances to reflect: (1) our proportionate share of net earnings/losses of the entities and accumulated other comprehensive income or loss, (2) distributions received, (3) contributions made, (4) sales and redemptions of our investments, and (5) certain other adjustments, as appropriate. When circumstances indicate there may have been a reduction in the value of an equity method investment, we evaluate whether or not the loss in value is other than temporary. If we determine that a loss in value is other than temporary, we recognize an impairment charge to reflect the equity investment at fair value. With regard to the cash flow classifications of distributions from unconsolidated entities, we have elected the nature of the distribution approach as the information is available to us to determine the nature of the underlying activity that generated the distributions. In accordance with this approach, cash flows generated from the operations of an unconsolidated entity are classified as a return on investment (cash inflow from operating activities) and cash flows that are generated from property sales, debt refinancing or sales and redemptions of our investments are classified as a return of investment (cash inflow from investing activities). The Company has a negligible value of investments accounted for under the cost-method. These investments are included in Other Assets on the consolidated balance sheets. Cash, Cash Equivalents and Restricted Cash. Restricted Cash . Assets Held for Sale. Investments in Real Estate. Investments in real estate are stated at cost, less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization is recorded on a straight-line basis over the estimated useful lives of the respective assts. Depreciable lives of assets are stated below. ​ ​ Investments in Real Estate. ​ ​ Acquired ground leases Terms of the related lease Buildings and improvements ​ 5-39 years Machinery and equipment ​ 7-15 years Furniture and fixtures ​ 3-5 years Leasehold improvements ​ Shorter of the estimated useful lives or the terms of the related leases 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. Capitalization of Costs. Development costs Leasing commissions ​ Recoverability of Real Estate Assets. We assess the carrying value of our properties whenever events or circumstances indicate carrying amounts of these assets may not be fully recoverable (“triggering events"). Triggering events typically relate to a change in the expected holding period of a property, an adverse change in expected future cash flows of the property, or a trend of past cash flow losses that is expected to continue in the future. If our assessment of triggering events indicates the carrying value of a property or asset group might not be recoverable, we estimate the future undiscounted net cash flows expected to be generated by the assets and compare that amount to the book value of the assets. If our future undiscounted net cash flow evaluation indicates we are unable to recover the carrying value of a property or asset group, we record an impairment loss to the extent the carrying value of the property or asset group exceeds fair value. We generally estimate fair value of rental properties using a discounted cash flow analysis that includes projections of future revenues, expenses, and capital improvements that a market participant would use. In certain cases, we may supplement this analysis by obtaining outside broker opinions of value. When determining undiscounted future cash flows, we consider factors such as future operating income trends and prospects as well as the effects of leasing demand, competition and other factors. Goodwill and Other Acquired Intangible Assets. Other acquired intangible assets consist primarily of customer relationship value and in-place lease value. All of our other acquired intangible assets have finite useful lives. If impairment indicators arise with respect to these finite-lived intangible assets, we evaluate for impairment by comparing the carrying amount of the assets to the estimated future undiscounted net cash flows expected to be generated by the assets. If estimated future undiscounted cash flows exceed the carrying value of the assets, we record an impairment charge equal to the amount by which the carrying value exceeds the estimated fair value of the assets. We have no indefinite-lived intangible assets other than goodwill. Share-Based Compensation. Derivative Instruments. Changes in the fair value of derivatives are recognized periodically either in earnings or in other comprehensive income (loss), depending on whether the derivative financial instrument is undesignated or qualifies for hedge accounting, and if so, whether it represents a fair value, cash flow, or net investment hedge. Gains and losses on derivatives designated as cash flow hedges, to the extent they are included in the assessment of effectiveness, are recorded in other comprehensive income (loss) and subsequently reclassified to earnings to offset the impact of the hedged items when they occur. In the event it becomes probable the forecasted transaction to which a cash flow hedge relates will not occur, the derivative would be terminated and the amount in other comprehensive income (loss) would be recognized in earnings. ​ Gains and losses representing components excluded from the assessment of effectiveness for cash flow and fair value hedges are recognized in earnings on a straight-line basis in the same caption as the hedged item over the term of the hedge. Gains and losses representing components excluded from the assessment of effectiveness for net investment hedges are recognized in earnings on a straight-line basis over the term of the hedge. ​ Interest Rate Swaps Interest rate derivatives are presented on a gross basis on the consolidated balance sheets – with interest rate swap assets presented in other assets, and interest rate swap liabilities presented in accounts payable and other accrued liabilities. As of December 31, 2022, there was no impact from netting arrangements, because the Company had no derivatives in liability positions. Net interest paid or received on interest rate swaps is recognized as interest expense. Gains and losses resulting from the early termination of interest rate swap agreements are deferred and amortized as adjustments to interest expense over the remaining period of the debt originally covered by the terminated swap. Foreign Currency Contracts Hedge of Net Investment in Foreign Operations Cross-Currency Interest Rate Swaps – See Note 17. “Derivative Instruments” for further discussion on the Company’s outstanding derivative instruments. Income Taxes. Digital Realty Trust, Inc. has elected to be treated as a real estate investment trust (a “REIT”) for federal income tax purposes. As a REIT, Digital Realty Trust, Inc. generally is not required to pay U.S. federal corporate income tax to the extent taxable income is currently distributed to its stockholders. If Digital Realty Trust, Inc. were to fail to qualify as a REIT in any taxable year, it would be subject to U.S. federal and state income taxes (including any applicable alternative minimum tax) on its taxable income. The Company is subject to foreign, state and local income taxes in the jurisdictions in which it conducts business. The Company’s taxable REIT subsidiaries are subject to federal, state, local and foreign income taxes to the extent there is taxable income. Accordingly, the Company recognizes current and deferred income taxes for the Company and its taxable REIT subsidiaries, including for U.S. federal, state, local and foreign jurisdictions, as applicable. 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, 2022 and 2021, 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 income statements. For the years ended December 31, 2022, 2021 and 2020, we had no such interest or penalties. We are open to examination by the major taxing jurisdictions for the tax years that are within the statute of limitations for those jurisdictions. See Note 13. “Income Taxes” for further discussion on income taxes. Transactional-based Taxes. Noncontrolling Interests and Redeemable Noncontrolling Interests. Noncontrolling interests represent the share of consolidated entities owned by third parties. We recognize each noncontrolling holder’s share of the fair value of the respective entity’s net assets as noncontrolling interest on our consolidated balance sheets at the date of formation or acquisition. Noncontrolling interest balances are adjusted for the noncontrolling holder’s share of additional contributions, distributions, and net earnings or losses. ​ Partnership units which are contingently redeemable for cash are classified as redeemable noncontrolling interests and presented in the mezzanine section of the Company’s consolidated balance sheets between total liabilities and stockholder’s equity. Redeemable noncontrolling interests include amounts related to partnership units issued by consolidated subsidiaries of the Company in which redemption for equity is outside the control of the Company. The amounts of consolidated net income attributable to noncontrolling interests and redeemable noncontrolling interests are presented on the Company’s consolidated income statements as income (or loss) attributable to noncontrolling interests. ​ Revenue Recognition. Rental And Other Services Revenue – We generate the majority of our revenue by leasing our properties to customers under operating lease agreements, which are accounted for under Accounting Standards Codification 842, Leases (“ASC 842”). We recognize the total minimum lease payments provided for under the leases on a straight-line basis over the lease term if we determine it is probable that substantially all of the lease payments will be collected over the lease term. We commence recognition of revenue from rentals at the date the property is ready for its intended use by the tenant and the tenant takes possession, or controls the physical use of the leased asset. The excess of rents recognized as revenue over amounts contractually due pursuant to the underlying leases is included in deferred rent. Rental payments received in excess of revenue recognized are classified as accounts payable and other accrued liabilities. Unpaid rents that are contractually due are included in accounts and other receivables. We estimate the probability of collection of lease payments based on customer creditworthiness, outstanding accounts receivable balances, and historical bad debts – as well as current economic trends. If collection of substantially all lease payments over the lease term is not probable, rental revenue is recognized when payment is received, and we record a full valuation allowance on the balance of any rent receivable, less the balance of any security deposits or letters of credit. If collection is subsequently determined to be probable, we: 1). resume recognizing rental revenue on a straight-line basis, 2). record incremental revenue such that the cumulative amount recognized is equal to the amount that would have been recorded on a straight-line basis since inception of the lease, and 3). reverse the allowance for bad debt recorded on outstanding receivables. Generally, under the terms of our leases, the majority of our rental expenses, including common area maintenance, real estate taxes and insurance, are recovered from our customers. We record amounts reimbursable by customers (“tenant recoveries”) as revenue in the period the applicable expenses are incurred – which is generally on a ratable basis through the term of the lease. ​ We account for and present rental revenue and tenant recoveries as a single component under rental and other services as the timing of recognition is the same, the pattern with which we transfer the right of use of the property and related services to the lessee are both on a straight-line basis and our leases qualify as operating leases. ​ Interconnection services include port and cross-connect services generally provided on a month-to-month, one-year or multi-year term. We bill for these services on a monthly basis and recognizes the revenue over the period the service is provided. Revenue for cross-connect installations is generally recognized in the period the cross-connect is installed. Interconnection services that are not specific to a particular leased space are accounted for under Topic 606 and have terms that are generally one year or less. ​ Fee Income And Other – We utilize the practical expedient in ASC 842 that allows us to account for lease and non-lease components associated with each lease as a single lease component recorded within rental and other services, instead of accounting for such items separately under Accounting Standards Codification 606, Revenue (“ASC 606”). We recognize revenue for items that do not qualify for revenue recognition under ASC 842 under ASC 606. Revenue recognized as a result of applying ASC 606 was less than 8% of total rental and other services revenue for the years ended December 31, 2022, 2021 and 2020. ​ Transaction and Integration Expense. Transaction expenses include closing costs, broker commissions and other professional fees, including legal and accounting fees related to business combinations or acquisitions that were not consummated. Integration costs include transition costs associated with organizational restructuring (such as severance and retention payments and recruiting expenses), third-party consulting expenses directly related to the integration of acquired companies (in areas such as cost savings and synergy realization, technology and systems work), and internal costs such as training, travel and labor, reflecting time spent by Company personnel on integration activities and projects. Recurring costs are recorded in general and administrative expense. ​ Gains on Disposition of Properties. We recognize gains on the disposition of real estate when the recognition criteria have been met, generally at the time the risks and rewards and title have transferred, and we no longer have substantial continuing involvement with the real estate sold. We recognize losses from the disposition of real estate when known. ​ New Accounting Pronouncements. Reference Rate Reform ​ In March 2020, the FASB issued an Accounting Standard Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting The first practical expedient within the ASU allows companies to elect to not apply certain modification accounting requirements to debt, derivative, and lease contracts affected by reference rate reform if certain criteria are met. The second practical expedient allows companies to change the reference rate and other critical terms related to the reference rate reform in derivative hedge documentation without having to designate the hedging relationship – allowing companies to continue applying hedge accounting to existing cash flow and net investment hedges. The ASU was effective on a prospective basis beginning January 1, 2020 and may be elected over time as reference rate reform activities occur. We will continue to evaluate debt, derivative, and lease contracts that are modified in the future to ensure they are eligible for modification relief and apply the available practical expedients as needed. Also, in December 2022, the FASB issued ASU 2022-06, Deferral of the Sunset Date of Topic 848 Business Combinations We determined that all other recently issued accounting pronouncements that have yet to be adopted by the Company will not have a material impact on our consolidated financial statements or do not apply to our operations.

Business Combinations On August 1, 2022, we completed the acquisition of a 61.1% indirect controlling interest in Teraco, a leading carrier-neutral data center and interconnection services provider in South Africa (the “Teraco Acquisition”). The total purchase price was $1.7 billion cash, funded by our global revolving credit facility and partial settlement of our forward equity sale agreements described under Note 14. “Equity and Capital—Forward Equity Sale.” Teraco controls (and consolidates) the Teraco Connect Trust (“the Trust”) that was created as part of the Broad Based Black Economic Empowerment Program in South Africa. The Trust owns a ​ The following table summarizes the amounts recorded at the acquisition date (in thousands): ​ ​ ​ ​ ​ ​ Final Amounts Building and improvements ​ $ 1,376,128 Construction in progress and space held for development ​ ​ 521,153 Operating lease right-of-use assets ​ ​ 2,784 Assumed cash and cash equivalents ​ ​ 5,528 Goodwill ​ 1,625,994 Customer relationship value and other intangibles (weighted-average amortization life of 14 years) ​ 720,126 Debt assumed ​ ​ (355,688) Operating lease liabilities ​ (4,031) Deferred tax liabilities, net ​ ​ (632,841) Redeemable noncontrolling interests ​ ​ (1,530,090) Working capital assets, net ​ ​ 1,112 Total purchase consideration ​ $ 1,730,175 ​ Goodwill ​ The Teraco acquisition was not material and neither the investment in the assets nor the results of operations of the acquisition was significant to the Company’s consolidated financial position or results of operations, and thus pro forma information is not required to be presented. Redeemable Noncontrolling Interest (“Redeemable NCI”) — ​ Since the Rollover Shareholders can redeem the put right at their discretion and such redemption, which could be in cash, is outside the Company’s control, the Company recorded the noncontrolling interest as Redeemable NCI and classified it in temporary equity within its consolidated balance sheets. The Redeemable NCI was initially recorded at its acquisition-date fair value and will be adjusted each reporting period for income (or loss) attributable to the noncontrolling interest (a $4.8 million net loss for the period from August 1, 2022 to December 31, 2022). If the contractual redemption value of the Redeemable NCI is greater than its carrying value, an adjustment is made to reflect Redeemable NCI at the higher of its contractual redemption value or its carrying value each reporting period. Changes to the redemption value are recognized immediately in the period the change occurs. If the redemption value of the Redeemable NCI is equal to or less than the fair market value of the Remaining Teraco Interest, the change in the redemption value will be adjusted through Additional Paid in Capital. If the redemption value is greater than the fair market value of the Remaining Teraco Interest, the change in redemption value will be adjusted through Retained Earnings. These adjustments are not reflected on the Company’s income statement, but are instead reflected as adjustments to the net income component of the Company’s earnings per share calculations. When calculating earnings per share attributable to Digital Realty Trust, Inc., the Company adjusts net income attributable to Digital Realty Trust, Inc. to the extent the redemption value exceeds the fair value of the Redeemable NCI on a cumulative basis. For the period from August 1, 2022 to December 31, 2022, no such adjustment was required.

The manner in which we recognize these transactions in our financial statements is described in Note 2. “Summary of Significant Accounting Policies—Revenue Recognition” to these consolidated financial statements. ​ A summary of minimum lease payments due from our customers under operating leases of land, prestabilized development properties, and operating properties with lease periods of greater than one year at December 31, 2022 (in thousands) is shown below. These amounts do not reflect future rental revenues from renewal or replacement of existing leases unless we are reasonably certain we will exercise the option or the lessee has the sole ability to exercise the option.

Leases for our data centers expire on various dates through 2069. Certain of our data centers, primarily in Europe and Singapore, are subject to ground leases. As of December 31, 2022, the termination dates of these ground leases ranged from 2027 to 2108. In addition, our corporate headquarters along with several regional office locations are subject to leases with termination dates ranging from 2023 to 2033. ​ The leases generally require us to make fixed rental payments that increase at defined intervals during the term of the lease plus pay our share of common area, real estate and utility expenses as incurred. The leases do not contain residual value guarantees and do not impose material restrictions or covenants on us. Further, the leases have been classified and accounted for as either operating or finance leases. Rent expense related to operating leases included in rental property operating and maintenance expense in the consolidated income statements amounted to approximately $144.0 million, $145.7 million and $120.5 million for the years ended December 31, 2022, 2021 and 2020, respectively. ​ As of December 31, 2022, the weighted average remaining lease term for our operating leases and finance leases was 12 years and 16 years, respectively. We do not include renewal options in the lease term for calculating the lease liability unless we are reasonably certain we will exercise the option or the lessor has the sole ability to exercise the option. The weighted average incremental borrowing rate was 3.0% for operating leases and 1.8% for finance leases at December 31, 2022. We assigned a collateralized interest rate to each lease based on the term of the lease and the currency in which the lease is denominated. ​ ​ ​ Maturities of lease liabilities as of December 31, 2022 were as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ Operating Finance ​ ​ lease liabilities ​ lease liabilities (1) 2023 ​ $ 190,279 ​ $ 36,905 2024 ​ 193,379 ​ 20,423 2025 ​ 195,002 ​ 20,468 2026 ​ 191,457 ​ 20,516 2027 ​ 187,873 ​ 21,003 Thereafter ​ 840,640 ​ 281,633 Total undiscounted future cash flows ​ 1,798,630 ​ 400,948 Less: Imputed interest ​ (327,586) ​ (75,720) Present value of undiscounted future cash flows ​ $ 1,471,044 ​ $ 325,228 (1) Included in accounts payable and other accrued liabilities on the consolidated balance sheet.

Acquisitions and Dispositions of Properties	7. Acquisitions and Dispositions of Properties ​ Acquisitions of Properties ​ For the years ended December 31, 2022, 2021 and 2020, acquisitions of properties that did not qualify as business combinations were immaterial to our financial statements – both individually and in the aggregate. ​ Disposition of Properties to Digital Core REIT ​ On December 6, 2021, we completed the listing of Digital Core REIT as a standalone real estate investment trust publicly traded on the Singapore Exchange (“SGX”) under the ticker symbol: DCRU. Hereafter, Digital Core REIT and its associated subsidiaries are collectively referred to as the Singapore REIT (“SREIT”). In connection with the listing, the Company contributed a portfolio of 10 operating data center properties to the SREIT. The fair value of these properties was determined to be approximately $1.4 billion based on two separate third party appraisal reports. In exchange for the contribution of these properties, the Company received: 1). $919 million cash and 2). a 39.4% equity interest in the publicly-traded Digital Core REIT entity, while retaining a 10% direct interest in the operating properties that were contributed by the Company to the SREIT. In addition, the Company received approximately $13 million of acquisition fees paid to the Company by Digital Core REIT in the form of additional units in Digital Core REIT. ​ The Company determined the fair market value of its 10% retained investment in the properties contributed to the SREIT based on its retained ownership percentage applied to the appraised value of the properties. This approach was deemed appropriate because the Company determined that a discount for lack of marketability and/or lack of control associated with its 10% direct interest in the properties was not warranted. ​ As a result of this transaction, the Company recognized a gain on sale of assets ​ ​ ​ ​ ​ ​ Cash received ​ $ 919.1 ​ Fair market value of retained investment in SREIT ​ ​ 521.4 ​ Acquisition fees paid in Digital Core REIT units ​ ​ 13.0 ​ Tax on acquisition fees ​ ​ (3.0) ​ Net book value of assets contributed ​ ​ (439.3) ​ Gain on disposition of properties ​ $ 1,011.2 ​ ​ The Company provides property management and other services to the SREIT in exchange for contractual fees that are payable to the Company in cash or in additional units of the SREIT. The Company’s retained investment in the SREIT is accounted for as an equity method investment, based on the conclusion that the Company has significant influence over (but does not control) the SREIT. On December 13, 2022, we completed the sale of a 25% interest in a data center facility in Frankfurt, Germany to the SREIT for total consideration of approximately $146 million. Because the Company still controls this asset, no gain or loss was recorded on this 25% interest. In connection with this transaction, the SREIT loaned the consolidated subsidiary that owns the data center $79.8 million. The assets and liabilities sold to the SREIT were not representative of a significant component of our portfolio, nor did the sale represent a significant shift in our strategy. Disposition of Other Properties The Company sold the following other real estate properties during the years ended December 31, 2022, 2021 and 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross Proceeds / Fair Value ​ Gain on Sale / contribution Location / Portfolio ​ Metro Area ​ Date Sold ​ (in millions) ​ (in millions) Non-core building ​ Dallas ​ Aug 8, 2022 ​ $ 203.0 ​ $ 174.0 Other ​ Various ​ 2022 ​ ​ 2.8 ​ ​ 2.8 European Portfolio ​ Various ​ Mar 16, 2021 ​ ​ 680.0 ​ ​ 332.0 Other ​ Various ​ 2021 ​ ​ 109.6 ​ ​ 37.7 Naritaweg 52 ​ Amsterdam ​ Dec 30, 2020 ​ ​ 6.1 ​ ​ — Liverpoolweg 10 ​ Amsterdam ​ Jul 17, 2020 ​ ​ 21.5 ​ ​ 10.4 Mapletree portfolio ​ Various ​ Jan 14, 2020 ​ ​ 557.0 ​ ​ 306.5 ​ Non-core Building - gain ​ European Portfolio gain ​ Mapletree Portfolio gain gain

The Company’s 35% interest in DCRU consists of 396 million units and 390 million units as of December 31, 2022 and December 31, 2021, respectively. Based on the closing price per unit of $0.55 and $1.16 as of December 31, 2022 and 2021, the fair value of the units the Company owns in DCRU was approximately $218 million and $453 million as of December 31, 2022 and 2021, respectively. ​ These values do not include the value of the Company’s 10% interest in the North American operating properties and 75% interest in the German operating property of DCRU, because the associated ownership interests are not publicly traded. The Company accounts for its investment in DCREIT as an equity method investment (and not at fair value) based on the significant influence it is able to exert on DCREIT. The Company determined that the decline in fair value of the investment in DCRU as compared to the Company’s book basis as of December 31, 2022 was temporary in nature. ​ Pursuant to contractual agreements with DCRU and its operating properties, the Company will earn fees for asset and property management services as well as fees for aiding in future acquisition, disposition and development activities. Certain of these fees are payable to the Company in the form of additional units in DCRU or in cash. During the years ended December 31, 2022 and 2021, the Company earned fees pursuant to these contractual agreements of approximately $10.6 million and $0.5 million, respectively, which is recorded as fee income and other on the consolidated income statement.

Goodwill	9. Goodwill Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired in a business combination. Changes in the value of goodwill at December 31, 2022 as compared to December 31, 2021 were primarily driven by the acquisition of an indirect majority interest in Teraco in August 2022 and changes in exchange rates associated with goodwill balances denominated in foreign currencies – primarily the devaluation of the Euro as compared to the U.S. dollar.

Global Revolving Credit Facility We have a global revolving senior credit facility (“global revolving credit facility”) under which we may draw up to $3.75 billion on a revolving basis (subject to currency fluctuations). The global revolving credit facility can be drawn in Australian dollars, British pounds sterling, Canadian dollars, Euros, Hong Kong dollars, Japanese yen, Singapore dollars, Indonesian rupiah, Swiss francs, Korean won and U.S. dollars (with the ability to add other currencies in the future). On April 5, 2022, we entered into an amendment (the “Amendment”) to the Second Amended and Restated Global Senior Credit Agreement (the “Credit Agreement”). The Amendment provided for, among other things: (1) an increase in the size of the global revolving credit facility from $3.0 billion to $3.75 billion and (2) the transition from U.S. dollar London Interbank Offered Rate (LIBOR) to Term Secured Overnight Financing Rate (SOFR) for floating rate borrowings denominated in U.S. dollars for all purposes under the Credit Agreement. We have the ability to increase the size of the global revolving credit facility by up to $750 million, subject to the receipt of lender commitments and other conditions precedent. Other key terms of the global revolving credit facility are as follows: ● Maturity date: January 24, 2026, with two six-month extension options available. The bank group is obligated to grant the extension options provided we give proper notice, we make certain representations and warranties and no default exists under the global revolving credit facilities. ● Interest rate: the applicable index plus a margin which is based on the credit ratings of our long-term debt and is currently 85 basis points. ● Annual facility fee: based on the total commitment amount of the facility and the credit ratings of our long-term debt is currently 20 basis points and is payable quarterly. ● Sustainability-linked pricing component: pricing can increase by up to 5 basis points or decrease by up to 5 basis points depending on whether or not the OP or its subsidiaries meet certain sustainability performance targets. Yen Revolving Credit Facility In addition to the global revolving credit facility, we have a revolving credit facility that provides for borrowings in Japanese Yen of up to ¥33.3 billion (approximately $253.9 million based on the exchange rate on December 31, 2022), hereafter referred to as the “Yen revolving credit facility”). We have the ability from time to time to increase the size of the Yen revolving credit facility to up to ¥93.3 billion (approximately $711.5 million based on the exchange rate on December 31, 2022), subject to receipt of lender commitments and other conditions precedent. Other key terms of the Yen revolving credit facility are as follows: ● Maturity date: January 24, 2026, with two six-month extension options available. The bank group is obligated to grant the extension options provided we give proper notice, we make certain representations and warranties and no default exists under the global revolving credit facilities. ● Interest rate: the applicable index plus a margin which is based on the credit ratings of our long-term debt and is currently 50 basis points. ● Quarterly unused commitment fee: currently is 10 basis points, calculated using the average daily unused revolving credit commitment and is based on the credit ratings of our long-term debt ● Sustainability-linked pricing component: pricing can increase by up to 5 basis points or decrease by up to 5 basis points depending on whether or not the OP or its subsidiaries meet certain sustainability performance targets. Restrictive Covenants in Global Revolving Credit Facility and Yen Revolving Credit Facility The global revolving credit facility and the Yen revolving credit facility both contain various restrictive covenants, including limitations on our ability to incur additional indebtedness, make certain investments, or merge with another company. In addition, we are required to maintain financial coverage ratios, including with ratios respect to unencumbered assets. After the occurrence of and during the continuance of any event of default, these credit facilities restrict the Parent’s ability to make distributions to stockholders or redeem or otherwise repurchase shares of its capital stock, except in limited circumstances (such as those 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, 2022, we were in compliance with all of such covenants for both of these revolving credit facilities.

The covenants also require us to maintain total unencumbered assets of not less than 150% of the aggregate principal amount of unsecured debt.

Early Extinguishment of Unsecured Senior Notes We recognized the following losses on early extinguishment of unsecured notes: ● During the year ended December 31, 2022 : $51.1 million primarily due to redemption of the 4.750% Notes due 2025 in February 2022. ● During the year ended December 31, 2021: $18.3 million primarily due to redemption of the 2.750% Notes due 2023 in February 2021. ● During the year ended December 31, 2020: $103.2 million primarily due to redemption of: o 3.950% Notes due 2022 and 3.625% Notes due 2022 in August 2020; and o 4.750% Notes due 2023 in October 2020 ​ Euro Term Loan Agreement On August 11, 2022, Digital Dutch Finco B.V., a wholly owned subsidiary of the Operating Partnership, entered into a term loan agreement (the “Euro Term Loan Agreement”) which governs (i) a €375.0 million three-year senior unsecured term loan facility (the “2025 Term Facility”), the entire amount of which was funded on the closing date, and (ii) a €375.0 million five-year senior unsecured term loan facility (the “2025-27 Term Facility” and, together with the 2025 Term Facility, the “Euro Term Facilities”), comprised of €125.0 million of initial term loans, the entire amount of which was funded on the closing date, and €250.0 million of delayed draw term loan commitments that were not funded on the closing date, and were funded on September 9, 2022.

Income Taxes	13. Income Taxes Digital Realty Trust, Inc. has elected to be treated and believes that it has been organized and has operated in a manner that has enabled it to qualify as a REIT for federal income tax purposes. As a REIT, Digital Realty Trust, Inc. is generally not subject to corporate level federal income taxes on taxable income distributed currently to its stockholders. Since inception, Digital Realty Trust, Inc. has distributed at least 100% of its taxable income annually. As such, no provision for federal income taxes has been included in the Company’s accompanying consolidated financial statements for the years ended December 31, 2022, 2021 and 2020. 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. We have elected taxable REIT subsidiary (“TRS”) status for some of our consolidated subsidiaries. In general, a TRS may provide services that would otherwise be considered impermissible for REITs to provide and may hold assets that REITs cannot hold directly. Income taxes for TRS entities were accrued, as necessary, for the years ended December 31, 2022, 2021 and 2020. For our TRS entities and foreign subsidiaries that are subject to U.S. federal, state, local and foreign income taxes, deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the temporary differences reverse. A valuation allowance for deferred tax assets is provided if we believe it is more likely than not that the deferred tax asset may not be realized, based on available evidence at the time the determination is made. An increase or decrease in the valuation allowance that results from the change in circumstances that causes a change in our judgment about the realizability of the related deferred tax asset is included in the income statement. Deferred tax assets (net of valuation allowance) and liabilities for our TRS entities and foreign subsidiaries were accrued, as necessary, for the years ended December 31, 2022, 2021 and 2020. As of December 31, 2022 and 2021, we had deferred tax liabilities net of deferred tax assets of approximately $1,184.6 million and $658.8 million, respectively, primarily related to our foreign properties, classified in accounts payable and other accrued expenses in the consolidated balance sheet. The majority of our net deferred tax liability relates to differences between foreign tax basis and book basis of the assets acquired in the Teraco Acquisition in August 2022, Interxion Combination in March 2020, the European Portfolio Acquisition in July 2016 and the Sentrum portfolio acquisition in 2012. The valuation allowance against the deferred tax assets at December 31, 2022 and 2021 relate primarily to net operating loss carryforwards that we do not expect to utilize attributable to certain foreign jurisdictions. Deferred income tax assets and liabilities as of December 31, 2022 and 2021 were as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ 2022 2021 Gross deferred income tax assets: ​ ​ ​ ​ Net operating loss carryforwards ​ $ 175,935 ​ $ 155,152 Basis difference - real estate property ​ 14,027 ​ 9,078 Basis difference - intangibles ​ 7,682 ​ 2,357 Basis difference - equity investments ​ ​ 5,694 ​ ​ — Straight-line rent ​ ​ — ​ ​ 8,097 Other - temporary differences ​ 132,578 ​ 175,766 Total gross deferred income tax assets ​ 335,916 ​ 350,450 Valuation allowance ​ (125,491) ​ (130,893) Total deferred income tax assets, net of valuation allowance ​ 210,425 ​ 219,557 Gross deferred income tax liabilities: ​ ​ Basis difference - real estate property ​ 1,160,412 ​ 798,640 Basis difference - equity investments ​ ​ — ​ ​ 3,543 Basis difference - intangibles ​ 219,653 ​ 63,222 Straight-line rent ​ 9,215 ​ 10,942 Other - temporary differences ​ 5,744 ​ 1,976 Total gross deferred income tax liabilities ​ 1,395,024 ​ 878,323 Net deferred income tax liabilities (1) ​ $ 1,184,599 ​ $ 658,766 ​ (1) Net of deferred tax assets of $8.2 million and $7.7 million for the year ended December 31, 2022 and 2021, respectively . ​ ​ ​ ​

Equity and Capital Equity Distribution Agreement Digital Realty Trust, Inc. and Digital Realty Trust, L.P. are parties to an at-the-market (ATM) equity offering sales agreement dated April 1, 2022 (the “Sales Agreement”). Pursuant to the Sales Agreement, Digital Realty Trust, Inc. can issue and sell common stock having an aggregate offering price of up to $1.5 billion through various named agents from time to time. For the year ended December 31, 2022, we had no sales under the Sales Agreement and $1.5 billion is still available. Forward Equity Sale On September 13, 2021, the Parent completed an underwritten public offering of 6,250,000 shares of its common stock, all of which were offered in connection with forward sale agreements it entered into with certain financial institutions acting as forward purchasers. The forward purchasers borrowed and sold an aggregate of 6,250,000 shares of the Parent’s common stock in the public offering. The Parent did not receive any proceeds from the sale of common stock by the forward purchasers in the public offering. During the year ended December 31, 2022, we settled the forward sale agreements in full by issuing approximately 6.3 million shares, resulting in proceeds of approximately $939.0 million.

Incentive Plans	​ ​ ​ 16. Incentive Plans ​ 2014 Incentive Award Plan ​ The Company provides incentive awards in the form of common stock or awards convertible into common stock pursuant to the Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2014 Incentive Award Plan, as amended (the “Incentive Plan”). The major categories of awards that can be issued under the Incentive Plan include: ​ Long-Term Incentive Units (“LTIP Units”) : ​ Service-Based Restricted Stock Units : ​ Market Performance-Based Awards (“the Performance Awards”) : ​ Market-Based Performance Awards. The market performance criterion compares the Company’s total shareholder return (“TSR”) relative to the MSCI US REIT Index (“RMS”) over a three-year performance period (“Market Performance Period”), subject to continued service, in order to determine the percentage of the total eligible pool of units that qualifies to be awarded. Following the completion of the Market Performance Period, the awards then have a time-based vesting element that allows for 50% of the performance-vested units to fully vest in the February immediately following the end of the Market Performance Period and 50% of the performance-vested units to fully vest in the subsequent February. Vesting with respect to the market condition is measured based on the difference between Digital Realty Trust, Inc.’s TSR percentage and the TSR percentage of the RMS as is shown in the subsequent table (the “RMS Relative Market Performance”). ​ ​ ​ ​ ​ ​ ​ ​ ​ Market ​ ​ ​ Performance ​ RMS Relative ​ Vesting Level Market Performance ​ Percentage Below Threshold Level ≤ -500 basis points ​ 0 % Threshold Level -500 basis points ​ 25 % Target Level 0 basis points ​ 50 % High Level ≥ 500 basis points ​ 100 % ​ If the RMS Relative Market Performance falls between the levels specified in the above table, the percentage of the award that will vest with respect to the market condition will be determined using straight-line linear interpolation between such levels. Following the completion of the applicable Market Performance Period, the Compensation Committee made the following determinations regarding the vesting of these awards. ​ 2020 Awards ● In January 2023, the RMS Relative Market Performance fell between the threshold and target level for the 2020 awards and accordingly, 72,230 Class D units and 7,083 Restricted Stock Units performance vested and qualified for time-based vesting. ● The Class D units included 5,841 distribution equivalent units that immediately vested on December 31, 2022. ● On February 27, 2023, 50% of the 2020 awards will vest and the remaining 50% will vest on February 27, 2024, subject to continued employment through the applicable vesting date. ​ 2019 Awards ● In January 2022, the RMS Relative Market Performance fell between the target and high level for the 2019 awards and accordingly, 239,436 Class D units and 70,721 Restricted Stock Units performance vested and qualified for time-based vesting. ● The Class D units included 18,966 distribution equivalent units that immediately vested on December 31, 2021. ● On February 27, 2022, 50% of the 2019 awards vested and the remaining 50% will vest on February 27, 2023, subject to continued employment through the applicable vesting date. ​ 2018 Awards ● In January 2021, the high level of the performance metric was determined to have been achieved and, accordingly, 240,377 Class D units and 63,498 Restricted Stock Units performance vested and qualified for time-based vesting. ● The Class D units included 20,725 distribution equivalent units that immediately vested on December 31, 2020. ● On February 27, 2021, 50% of the 2018 awards vested and the remaining 50% vested on February 27, 2022, subject to continued employment through the applicable vesting date. ​ ​ ​ ​ ​ ​ Financial-Based Performance Awards. ​ On March 4, 2022, the Company granted Financial-Based Performance Awards, based on growth in core funds from operation (“Core FFO”) during the three-year period commencing on January 1, 2022. The awards then have a time-based vesting element consistent with the Market-Based Performance Awards discussed above. For these awards, fair value is based on market value on the date of grant and compensation cost is recognized based on the probable achievement of the performance condition at each reporting period. The grant date fair value of these awards is $12.3 million, based on the Company’s closing stock price at the grant date. ​ Fair Value of Market Performance-Based Awards ​ The fair values of the Performance Awards granted were measured using a Monte Carlo simulation to estimate the probability of the market vesting condition being satisfied. The Monte Carlo simulation is a probabilistic technique based on the underlying theory of the Black-Scholes formula, which was run for 100,000 trials to determine the fair value of the awards. For each trial, the payoff to an award is calculated at the settlement date and is then discounted to the grant date at a risk-free interest rate. The total expected value of the awards on the grant date was determined by multiplying the average value per award over all trials by the number of awards granted. Assumptions used in the valuations are summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ Expected Stock Price Risk-Free Interest ​ Award Date Volatility rate ​ February 19, 2020 ​ 22 % 1.39 % February 20, 2020 ​ 22 % 1.35 % January 1, 2021 ​ 27 % 0.17 % February 25, 2021 ​ 26 % 0.31 % January 1, 2022 ​ 26 % 0.97 % ​ The expected stock price volatility assumption is calculated based on our historical volatility, which is calculated over a period of time commensurate with the expected term of the awards being valued. The expected dividend yield assumption used in the Monte Carlo simulation represents the percent of return to a stock that is available to the holder of an award. Because the holders of the awards receive dividend equivalents, an expected dividend yield assumption of 0.00% was used in the valuation. These valuations were performed in a risk-neutral framework, and no assumption was made with respect to an equity risk premium. ​ The grant date fair value of the Performance Awards was approximately $12.3 million, $25.0 million and $17.2 million for the years ended years ended December 31, 2022, 2021 and 2020, respectively. We will recognize compensation expense on a straight-line basis over the expected service period of approximately four years. ​ The aggregate intrinsic value of the Performance Awards that vested in 2022, 2021 and 2020 was $41.2 million, $28.6 million and $24.3 million, respectively. ​ Other Items : In addition to the LTIP Units, service-based Restricted Stock Units and Performance Awards described above, one-time grants of time and/or performance-based Class D units and Restricted Stock Units were issued in connection with the Interxion Combination.

Derivative Instruments Derivatives Designated as Hedging Instruments Net Investment Hedges ​ In September 2022, we entered into cross-currency interest rate swaps, which effectively convert a portion of our U.S. dollar-denominated fixed-rate debt to foreign currency-denominated fixed-rate debt in order to hedge the currency exposure associated with our net investment in foreign subsidiaries. As of December 31, 2022, we had cross-currency interest rate swaps outstanding with notional amounts of $1.67 billion and maturity dates ranging through 2028. We had no such instruments outstanding as of December 31, 2021. ​ The effect of these net investment hedges on accumulated other comprehensive income and the consolidated income statements for the years ended December 31, 2022, 2021 and 2020 was as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ ​ 2022 2021 2020 Cross-currency interest rate swaps (included component) (1) ​ $ 116,550 ​ $ — ​ $ — Cross-currency interest rate swaps (excluded component) (2) ​ ​ (7,929) ​ ​ — ​ ​ — Total ​ $ 108,621 ​ $ — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ ​ ​ Location of gain or (loss) ​ ​ 2022 2021 2020 Cross-currency interest rate swaps (excluded component) (2) ​ ​ Interest expense ​ ​ $ 6,260 ​ $ — ​ $ — (1) Included component represents foreign exchange spot rates.

Amounts reported in accumulated other comprehensive loss related to interest rate swaps are reclassified to interest expense as interest payments are made on our debt. As of December 31, 2022, we had no material interest rate swap agreements outstanding. On December 13, 2021, in connection with the paydown of our secured note due March 2023, we terminated interest rate swap agreements with notional amounts in the aggregate of $104.0 million and, as a result of the termination, the accumulated fair value of the interest rate swap will be ratably reclassified from accumulated other comprehensive income to interest expense on the accompanying consolidated income statement over the original term of the interest rate swap. On September 24, 2020, in connection with the paydown of our Term Loan maturing in 2023, we terminated interest rate swap agreements with notional amounts in the aggregate of $300.0 million, as a result of the termination, the accumulated fair value of the interest rate swap was reclassified from accumulated other comprehensive income to interest expense ​ Fair Value of Derivative Instruments ​ The subsequent table presents the fair value of derivative instruments recognized in our consolidated balance sheets as of December 31, 2022 and 2021 (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2022 ​ December 31, 2021 ​ Assets (1) Liabilities (2) Assets (1) Liabilities (2) Cross-currency interest rate swaps ​ $ — ​ $ 108,621 ​ $ — ​ $ — (1) As presented in our consolidated balance sheets within other assets.

Fair Value of Financial Instruments
Fair Value of Financial Instruments	18. Fair Value of Financial Instruments We disclose fair value information for all financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practicable to estimate fair value. Considerable judgment is necessary to interpret market data in order to estimate the fair value of financial instruments. The use of different market assumptions or estimation methods may have a material effect on the estimated fair value amounts. ​ The carrying amounts for cash and cash equivalents, restricted cash, accounts and other receivables, accounts payable and other accrued liabilities, accrued dividends and distributions, security deposits and prepaid rents approximate fair value because of the short-term nature of these instruments. The carrying value of our global revolving credit facilities and unsecured term loans approximates estimated fair value, because these liabilities have variable interest rates and our credit ratings have remained stable. Differences between the carrying value and fair value of our unsecured senior notes and secured and other debt are caused by differences in interest rates or borrowing spreads that were available to us on December 31, 2022 and 2021 as compared to those in effect when the debt was issued or assumed. As described in Note 17. "Derivative Instruments", outstanding derivative contracts are recorded at fair value. ​ We calculate the fair value of our secured and other debt and unsecured senior notes based on currently available market rates assuming the loans are outstanding through maturity and considering the collateral and other loan terms. In determining the current market rate for fixed rate debt, a market spread is added to the quoted yields on federal government treasury securities with similar maturity dates to our debt. ​ The aggregate estimated fair value and carrying value of our global revolving credit facilities, unsecured term loans, unsecured senior notes and secured debt as of the respective periods is shown below (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Categorization ​ As of December 31, 2022 ​ As of December 31, 2021 ​ ​ under the fair value ​ Estimated Fair ​ ​ ​ ​ Estimated Fair ​ ​ ​ ​ hierarchy Value Carrying Value Value Carrying Value Global revolving credit facilities Level 2 ​ $ 2,167,889 ​ $ 2,167,889 ​ $ 415,116 ​ $ 415,116 Unsecured term loans (1) Level 2 ​ ​ 802,875 ​ ​ 802,875 ​ ​ — ​ ​ — Unsecured senior notes (2) Level 2 ​ ​ 11,331,989 ​ ​ 13,220,961 ​ 13,580,262 ​ 13,000,042 Secured and other debt (2) Level 2 ​ ​ 517,226 ​ ​ 532,130 ​ 152,511 ​ 147,082 ​ ​ ​ ​ $ 14,819,979 ​ $ 16,723,855 ​ $ 14,147,889 ​ $ 13,562,240 (1) The carrying value of our unsecured term loans approximates estimated fair value, due to the variability of interest rates and the stability of our credit ratings.

General
Organization and Description of Business	Organization and Description of Business. The Parent’s only material asset is its ownership of partnership interests of the OP. The Parent generally does not conduct business itself, other than acting as the sole general partner of the OP, issuing public securities from time to time and guaranteeing certain unsecured debt of the OP and certain of its subsidiaries and affiliates. The Parent has not issued any debt but guarantees the unsecured debt of the OP and certain of its subsidiaries and affiliates. The OP holds substantially all the assets of the Company. The OP conducts the operations of the business and has no publicly traded equity. Except for net proceeds from public equity issuances by the Parent, which are generally contributed to the OP in exchange for partnership units, the OP generally generates the capital required by the Company’s business primarily through the OP’s operations, by the OP’s or its affiliates’ direct or indirect incurrence of indebtedness or through the issuance of partnership units.
Accounting Principles and Basis of Presentation	Accounting Principles and Basis of Presentation.
Management Estimates and Assumptions	Management Estimates and Assumptions . U.S. GAAP requires us to make estimates and assumptions that affect reported amounts of revenue and expenses during the reporting period, reported amounts for assets and liabilities as of the date of the financial statements, and disclosures of contingent assets and liabilities as of the date of the financial statements. Although we believe the estimates and assumptions we made are reasonable and appropriate, as discussed in the applicable sections throughout the consolidated financial statements, different assumptions and estimates could materially impact our reported results. Actual results and outcomes may differ from our assumptions.
Consolidation	Consolidation We consolidate all entities that are wholly owned as well as all partially-owned entities that we control. In addition, we consolidate any variable interest entities (“VIEs”) for which we are the primary beneficiary. We evaluate whether or not an entity is a VIE (and we are the primary beneficiary) through consideration of substantive terms in the arrangement to identify which enterprise has the power to direct the activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses/receive benefits from the entity. For entities that do not meet the definition of VIEs, we first consider if we are the general partner or a limited partner (or the equivalent in investments not structured as partnerships). We consolidate entities in which we are the general partner and the limited partners do not have rights that would preclude control. For entities in which we are the general partner, but the limited partners hold substantive participating or kick-out rights that prohibit our ability to control the entity, we apply the equity method of accounting since, as the general partner, we have the ability to exercise significant influence over the operating and financial policies of the entities. For entities in which we are a limited partner, or that are not structured similar to a partnership, we consider factors such as ownership interest, voting control, authority to make decisions and contractual and substantive participating rights of the partners. When factors indicate we have a controlling financial interest in an entity, we consolidate the entity.
Foreign Operations and Foreign Currencies	Foreign Operations and Foreign Currencies. The functional currency of each of our consolidated subsidiaries and unconsolidated entities operating in other countries is the principal currency in which each entity’s assets, liabilities, income and expenses are denominated, which may be different from the local currency of incorporation or the currency with which the entities conduct their operations. The primary functional currencies impacting our business include the Euro, Japanese yen, British pound sterling, Singapore dollar, South African rand and Brazilian real. For our consolidated subsidiaries whose functional currency is not the U.S. dollar, we translate financial statements into U.S. dollars at the time we consolidate these subsidiaries’ financial statements. Generally, assets and liabilities are translated at the exchange rate in effect at the balance sheet date. Certain balance sheet items, such as equity and capital-related accounts are reflected at historical exchange rates. Income statement accounts are generally translated at the average exchange rates for the reporting periods. We and certain of our consolidated subsidiaries have intercompany and third-party debt that is not denominated in the functional currency of the entities. When debt is denominated in a currency other than the functional currency of an entity, a gain or loss can result. The associated adjustment is reflected in other (expenses) income, net, in the consolidated income statements, unless it is intercompany debt that is deemed to be long-term in nature or third-party debt that has been designated as a nonderivative net investment hedge – in which case the associated adjustments are reflected as a cumulative translation adjustments as a component of other comprehensive income. In the statement of cash flows, cash flows denominated in foreign currencies are translated using the exchange rates in effect at the time of the respective cash flows or at average exchange rates for the period, depending on the nature of the cash flow items.
Acquisition Accounting	Acquisition Accounting . We evaluate whether or not substantially all of the value of acquired assets is concentrated in a single identifiable asset or group of identifiable assets to determine whether a transaction is accounted for as an asset acquisition or a business combination. For asset acquisitions: (1) transaction costs are included in the total costs of the acquisition and are allocated on a pro-rata basis to the carrying value of the assets and liabilities acquired, (2) real estate assets acquired are measured based on their cost or total consideration exchanged with any excess consideration or bargain purchase amount allocated to real estate properties and their associated intangibles such as above and below-market leases, in-place leases, acquired ground leases, and customer relationship value and (3) all other assets and liabilities assumed, including any debt, are recorded at fair value. For business combinations: (1) transaction costs are expensed as incurred, (2) all acquired tangible and identifiable intangible assets are recognized at fair value, (3) the amount of any purchase consideration that exceeds the fair value of the tangible and identifiable intangible assets acquired is recognized as goodwill, and (4) to the extent the purchase consideration is less than the fair value of the tangible and identifiable intangible assets acquired, a gain on bargain purchase is recognized. When we obtain control of an unconsolidated entity that we previously held as an equity method investment and the acquisition qualifies as a business combination, we remeasure our previously held interest in the unconsolidated entity at its acquisition-date fair value, derecognize the book value associated with that interest, and recognize any resulting gain or loss in earnings. We allocate purchase price primarily using Level 2 and Level 3 inputs (further defined in Fair Value Measurements) as follows: Real Estate Lease Intangibles. ● Above and below market leases: We use a discounted cash flow approach to determine the estimated present value of any difference between contractual rents for acquired in-place leases as compared to current market rents. If rents on acquired in-place leases are higher than current market rents, we record an intangible asset for the favorable rents. If rents on acquired in-place leases are lower than current market rents, we record a liability for the unfavorable rents. Favorable rent assets are amortized as a reduction to rental income over the remaining non-cancelable term of the lease. Unfavorable rent liabilities are amortized as an increase to rental income over the initial lease term plus any below-market fixed rate renewal periods. ● In-place lease value: Since the as-if-vacant model is used to determine the value of acquired operating properties, the value of such properties does not include the value associated with having existing tenants who are leasing space in the purchased properties. Having in-place tenants allows buyers to avoid costs associated with leasing the property as well as any rent losses and unreimbursed operating expenses during the lease-up period. An asset for such benefits is recorded separately as in-place lease value. In-place lease value is determined based on estimated carrying costs during hypothetical expected lease-up periods as well as costs to execute similar leases. We determine expected carrying costs and costs to execute similar leases in the same manner as described in the previous discussion of the valuation of operating properties using the as-if-vacant model. The value of in-place leases is amortized to expense over the remaining initial terms of the respective leases. ● Customer relationship value: In some transactions, customers acquired are expected to generate recurring revenues beyond existing in-place lease terms. We utilize the multi-period excess earnings method to determine value customer relationship value, if any. Key factors reflected in this approach include: (1) projected revenue growth from existing customers, (2) historical customer lease renewals and attrition rates, (3) rental renewal probabilities and related market terms, (4) estimated operating costs, and (5) discount rate. Customer relationship value is amortized to expense ratably over the anticipated life of substantially all of the acquired customer relationships that are expected to generate excess earnings. Debt. Noncontrolling interests. Other acquired assets and liabilities.
Fair Value Measurements	Fair Value Measurements. Fair value is intended to reflect the price that would be received for the sale of an asset or paid for the transfer of a liability in an orderly transaction between market participants at the measurement date (the exit price). We estimate fair value using available market information and valuation methods we believe to be appropriate for these purposes. Given the significant amount of judgement and subjectivity involved in the determination of fair value, estimated fair value is not necessarily indicative of amounts that would be realized on disposition. There are three levels in the fair value hierarchy under US GAAP, which are: ● Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that an entity can access at the measurement date. ● Level 2 – Inputs that are directly or indirectly observable for the associated asset or liability, but which do not qualify as Level 1 inputs. ● Level 3 – Unobservable inputs for the asset or liability. In instances where inputs from multiple different levels of the fair value hierarchy are used to determine fair value, the lowest level input that is significant is used to determine the fair-value measurement in its entirety. Our assessment of the significance of a particular input to a fair-value measurement requires judgment and considers factors specific to the asset or liability. We utilize fair value measurements on a recurring basis to determine the fair value of: marketable equity securities, share-based compensation awards, derivative instruments, and outstanding debt. Such measurements are also regularly utilized in assessing whether or not impairments may exist on intangible assets (including goodwill). In addition, we utilize fair value measurements on a non-recurring basis to determine the fair value associated with assets held for sale, acquisitions of assets, and acquisitions of businesses.
Investments in Unconsolidated Entities	Investments in Unconsolidated Entities. Investments in unconsolidated entities as reflected on the consolidated balance sheets includes all investments accounted for using the equity method. We use the equity method to account for these investments, because we have the ability to exercise significant influence over their operating and financial policies, but do not control them. Equity method investments are initially recognized at our cost. Transaction costs related to the formation of equity method investments are also capitalized. We subsequently adjust these balances to reflect: (1) our proportionate share of net earnings/losses of the entities and accumulated other comprehensive income or loss, (2) distributions received, (3) contributions made, (4) sales and redemptions of our investments, and (5) certain other adjustments, as appropriate. When circumstances indicate there may have been a reduction in the value of an equity method investment, we evaluate whether or not the loss in value is other than temporary. If we determine that a loss in value is other than temporary, we recognize an impairment charge to reflect the equity investment at fair value. With regard to the cash flow classifications of distributions from unconsolidated entities, we have elected the nature of the distribution approach as the information is available to us to determine the nature of the underlying activity that generated the distributions. In accordance with this approach, cash flows generated from the operations of an unconsolidated entity are classified as a return on investment (cash inflow from operating activities) and cash flows that are generated from property sales, debt refinancing or sales and redemptions of our investments are classified as a return of investment (cash inflow from investing activities). The Company has a negligible value of investments accounted for under the cost-method. These investments are included in Other Assets on the consolidated balance sheets.

Investments in Real Estate	Investments in Real Estate. Investments in real estate are stated at cost, less accumulated depreciation and amortization. Land is not depreciated. Depreciation and amortization is recorded on a straight-line basis over the estimated useful lives of the respective assts. Depreciable lives of assets are stated below. ​ ​ Investments in Real Estate. ​ ​ Acquired ground leases Terms of the related lease Buildings and improvements ​ 5-39 years Machinery and equipment ​ 7-15 years Furniture and fixtures ​ 3-5 years Leasehold improvements ​ Shorter of the estimated useful lives or the terms of the related leases 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.
Capitalization of Costs	Capitalization of Costs. Development costs Leasing commissions ​
Recoverability of Real Estate Assets	Recoverability of Real Estate Assets. We assess the carrying value of our properties whenever events or circumstances indicate carrying amounts of these assets may not be fully recoverable (“triggering events"). Triggering events typically relate to a change in the expected holding period of a property, an adverse change in expected future cash flows of the property, or a trend of past cash flow losses that is expected to continue in the future. If our assessment of triggering events indicates the carrying value of a property or asset group might not be recoverable, we estimate the future undiscounted net cash flows expected to be generated by the assets and compare that amount to the book value of the assets. If our future undiscounted net cash flow evaluation indicates we are unable to recover the carrying value of a property or asset group, we record an impairment loss to the extent the carrying value of the property or asset group exceeds fair value. We generally estimate fair value of rental properties using a discounted cash flow analysis that includes projections of future revenues, expenses, and capital improvements that a market participant would use. In certain cases, we may supplement this analysis by obtaining outside broker opinions of value. When determining undiscounted future cash flows, we consider factors such as future operating income trends and prospects as well as the effects of leasing demand, competition and other factors.
Goodwill and Other Acquired Intangible Assets	Goodwill and Other Acquired Intangible Assets. Other acquired intangible assets consist primarily of customer relationship value and in-place lease value. All of our other acquired intangible assets have finite useful lives. If impairment indicators arise with respect to these finite-lived intangible assets, we evaluate for impairment by comparing the carrying amount of the assets to the estimated future undiscounted net cash flows expected to be generated by the assets. If estimated future undiscounted cash flows exceed the carrying value of the assets, we record an impairment charge equal to the amount by which the carrying value exceeds the estimated fair value of the assets. We have no indefinite-lived intangible assets other than goodwill.
Share-Based Compensation	Share-Based Compensation.
Derivative Instruments	Derivative Instruments. Changes in the fair value of derivatives are recognized periodically either in earnings or in other comprehensive income (loss), depending on whether the derivative financial instrument is undesignated or qualifies for hedge accounting, and if so, whether it represents a fair value, cash flow, or net investment hedge. Gains and losses on derivatives designated as cash flow hedges, to the extent they are included in the assessment of effectiveness, are recorded in other comprehensive income (loss) and subsequently reclassified to earnings to offset the impact of the hedged items when they occur. In the event it becomes probable the forecasted transaction to which a cash flow hedge relates will not occur, the derivative would be terminated and the amount in other comprehensive income (loss) would be recognized in earnings. ​ Gains and losses representing components excluded from the assessment of effectiveness for cash flow and fair value hedges are recognized in earnings on a straight-line basis in the same caption as the hedged item over the term of the hedge. Gains and losses representing components excluded from the assessment of effectiveness for net investment hedges are recognized in earnings on a straight-line basis over the term of the hedge. ​ Interest Rate Swaps Interest rate derivatives are presented on a gross basis on the consolidated balance sheets – with interest rate swap assets presented in other assets, and interest rate swap liabilities presented in accounts payable and other accrued liabilities. As of December 31, 2022, there was no impact from netting arrangements, because the Company had no derivatives in liability positions. Net interest paid or received on interest rate swaps is recognized as interest expense. Gains and losses resulting from the early termination of interest rate swap agreements are deferred and amortized as adjustments to interest expense over the remaining period of the debt originally covered by the terminated swap. Foreign Currency Contracts Hedge of Net Investment in Foreign Operations Cross-Currency Interest Rate Swaps – See Note 17. “Derivative Instruments” for further discussion on the Company’s outstanding derivative instruments.
Income Taxes	Income Taxes. Digital Realty Trust, Inc. has elected to be treated as a real estate investment trust (a “REIT”) for federal income tax purposes. As a REIT, Digital Realty Trust, Inc. generally is not required to pay U.S. federal corporate income tax to the extent taxable income is currently distributed to its stockholders. If Digital Realty Trust, Inc. were to fail to qualify as a REIT in any taxable year, it would be subject to U.S. federal and state income taxes (including any applicable alternative minimum tax) on its taxable income. The Company is subject to foreign, state and local income taxes in the jurisdictions in which it conducts business. The Company’s taxable REIT subsidiaries are subject to federal, state, local and foreign income taxes to the extent there is taxable income. Accordingly, the Company recognizes current and deferred income taxes for the Company and its taxable REIT subsidiaries, including for U.S. federal, state, local and foreign jurisdictions, as applicable. 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, 2022 and 2021, 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 income statements. For the years ended December 31, 2022, 2021 and 2020, we had no such interest or penalties. We are open to examination by the major taxing jurisdictions for the tax years that are within the statute of limitations for those jurisdictions. See Note 13. “Income Taxes” for further discussion on income taxes.
Transactional-based Taxes	Transactional-based Taxes.
Noncontrolling Interests and Redeemable Noncontrolling Interests	Noncontrolling Interests and Redeemable Noncontrolling Interests. Noncontrolling interests represent the share of consolidated entities owned by third parties. We recognize each noncontrolling holder’s share of the fair value of the respective entity’s net assets as noncontrolling interest on our consolidated balance sheets at the date of formation or acquisition. Noncontrolling interest balances are adjusted for the noncontrolling holder’s share of additional contributions, distributions, and net earnings or losses. ​ Partnership units which are contingently redeemable for cash are classified as redeemable noncontrolling interests and presented in the mezzanine section of the Company’s consolidated balance sheets between total liabilities and stockholder’s equity. Redeemable noncontrolling interests include amounts related to partnership units issued by consolidated subsidiaries of the Company in which redemption for equity is outside the control of the Company. The amounts of consolidated net income attributable to noncontrolling interests and redeemable noncontrolling interests are presented on the Company’s consolidated income statements as income (or loss) attributable to noncontrolling interests. ​
Revenue Recognition	Revenue Recognition. Rental And Other Services Revenue – We generate the majority of our revenue by leasing our properties to customers under operating lease agreements, which are accounted for under Accounting Standards Codification 842, Leases (“ASC 842”). We recognize the total minimum lease payments provided for under the leases on a straight-line basis over the lease term if we determine it is probable that substantially all of the lease payments will be collected over the lease term. We commence recognition of revenue from rentals at the date the property is ready for its intended use by the tenant and the tenant takes possession, or controls the physical use of the leased asset. The excess of rents recognized as revenue over amounts contractually due pursuant to the underlying leases is included in deferred rent. Rental payments received in excess of revenue recognized are classified as accounts payable and other accrued liabilities. Unpaid rents that are contractually due are included in accounts and other receivables. We estimate the probability of collection of lease payments based on customer creditworthiness, outstanding accounts receivable balances, and historical bad debts – as well as current economic trends. If collection of substantially all lease payments over the lease term is not probable, rental revenue is recognized when payment is received, and we record a full valuation allowance on the balance of any rent receivable, less the balance of any security deposits or letters of credit. If collection is subsequently determined to be probable, we: 1). resume recognizing rental revenue on a straight-line basis, 2). record incremental revenue such that the cumulative amount recognized is equal to the amount that would have been recorded on a straight-line basis since inception of the lease, and 3). reverse the allowance for bad debt recorded on outstanding receivables. Generally, under the terms of our leases, the majority of our rental expenses, including common area maintenance, real estate taxes and insurance, are recovered from our customers. We record amounts reimbursable by customers (“tenant recoveries”) as revenue in the period the applicable expenses are incurred – which is generally on a ratable basis through the term of the lease. ​ We account for and present rental revenue and tenant recoveries as a single component under rental and other services as the timing of recognition is the same, the pattern with which we transfer the right of use of the property and related services to the lessee are both on a straight-line basis and our leases qualify as operating leases. ​ Interconnection services include port and cross-connect services generally provided on a month-to-month, one-year or multi-year term. We bill for these services on a monthly basis and recognizes the revenue over the period the service is provided. Revenue for cross-connect installations is generally recognized in the period the cross-connect is installed. Interconnection services that are not specific to a particular leased space are accounted for under Topic 606 and have terms that are generally one year or less. ​ Fee Income And Other – We utilize the practical expedient in ASC 842 that allows us to account for lease and non-lease components associated with each lease as a single lease component recorded within rental and other services, instead of accounting for such items separately under Accounting Standards Codification 606, Revenue (“ASC 606”). We recognize revenue for items that do not qualify for revenue recognition under ASC 842 under ASC 606. Revenue recognized as a result of applying ASC 606 was less than 8% of total rental and other services revenue for the years ended December 31, 2022, 2021 and 2020. ​
Transaction and Integration Expense	Transaction and Integration Expense. Transaction expenses include closing costs, broker commissions and other professional fees, including legal and accounting fees related to business combinations or acquisitions that were not consummated. Integration costs include transition costs associated with organizational restructuring (such as severance and retention payments and recruiting expenses), third-party consulting expenses directly related to the integration of acquired companies (in areas such as cost savings and synergy realization, technology and systems work), and internal costs such as training, travel and labor, reflecting time spent by Company personnel on integration activities and projects. Recurring costs are recorded in general and administrative expense. ​
Gains on Disposition of Properties	Gains on Disposition of Properties. We recognize gains on the disposition of real estate when the recognition criteria have been met, generally at the time the risks and rewards and title have transferred, and we no longer have substantial continuing involvement with the real estate sold. We recognize losses from the disposition of real estate when known. ​
New Accounting Pronouncements	New Accounting Pronouncements. Reference Rate Reform ​ In March 2020, the FASB issued an Accounting Standard Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting The first practical expedient within the ASU allows companies to elect to not apply certain modification accounting requirements to debt, derivative, and lease contracts affected by reference rate reform if certain criteria are met. The second practical expedient allows companies to change the reference rate and other critical terms related to the reference rate reform in derivative hedge documentation without having to designate the hedging relationship – allowing companies to continue applying hedge accounting to existing cash flow and net investment hedges. The ASU was effective on a prospective basis beginning January 1, 2020 and may be elected over time as reference rate reform activities occur. We will continue to evaluate debt, derivative, and lease contracts that are modified in the future to ensure they are eligible for modification relief and apply the available practical expedients as needed. Also, in December 2022, the FASB issued ASU 2022-06, Deferral of the Sunset Date of Topic 848 Business Combinations We determined that all other recently issued accounting pronouncements that have yet to be adopted by the Company will not have a material impact on our consolidated financial statements or do not apply to our operations.
