Business Overview and Strategy
Digital Realty Trust, Inc. , through its controlling interest inDigital Realty Trust, L.P. and its subsidiaries, delivers comprehensive space, power, and interconnection solutions that enable its customers and partners to connect with each other and service their own customers on a global technology and real estate platform. We are a leading global provider of data center, colocation and interconnection solutions for customers across a variety of industry verticals ranging from cloud and information technology services, social networking and communications to financial services, manufacturing, energy, healthcare, and consumer products.Digital Realty Trust, Inc. operates as a REIT for federal income tax purposes, and ourOperating Partnership is the entity through which we conduct our business and own our assets.
Our primary business objectives are to maximize:
(i) sustainable long-term growth in earnings and funds from operations per share
and unit;
(ii) cash flow and returns to our stockholders and our
unitholders through the payment of distributions; and
(iii) return on invested capital.
We expect to accomplish our objectives by achieving superior risk-adjusted returns, prudently allocating capital, diversifying our product offerings, accelerating our global reach and scale, and driving revenue growth and operating efficiencies. A significant component of our current and future internal growth is anticipated through the development of our existing space held for development, acquisition of land for future development, and acquisition of new properties.
We target high-quality, strategically located properties containing the physical and connectivity infrastructure that supports the applications and operations of data center and technology industry customers and properties that may be developed for such use. Most of our data center properties contain fully redundant electrical supply systems, multiple power feeds, above-standard cooling systems, raised floor areas, extensive in-building communications cabling and high-level security systems. We focus exclusively on owning, acquiring, developing and operating data centers because we believe that the growth in data center demand and the technology-related real estate industry generally will continue to outpace the overall economy. 39
Table of Contents
We have developed detailed, standardized procedures for evaluating new real estate investments to ensure that they meet our financial, technical and other criteria. We expect to continue to acquire additional assets as part of our growth strategy. We intend to aggressively manage and lease our assets to increase their cash flow. We may continue to build out our development portfolio when justified by anticipated demand and returns. We may acquire properties subject to existing mortgage financing and other indebtedness or we may incur new indebtedness in connection with acquiring or refinancing these properties. Debt service on such indebtedness will have a priority over any cash dividends with respect toDigital Realty Trust, Inc.'s common stock and preferred stock. We are committed to maintaining a conservative capital structure. We target a debt-to-Adjusted EBITDA ratio at or less than 5.5x, fixed charge coverage of greater than three times, and floating rate debt at less than 20% of total outstanding debt. In addition, we strive to maintain a well-laddered debt maturity schedule, and we seek to maximize the menu of our available sources of capital, while minimizing the cost.
Revenue Base
The majority of revenue consists of rental income generated by the data centers in our portfolio. Our ability to generate and grow revenue depends on several factors, including our ability to maintain or improve occupancy rates. As ofJune 30, 2021 andDecember 31, 2020 , our portfolio (excluding space under development or held for development) was 84.7% and 86.3% leased, respectively. A summary of our data center portfolio and related square feet occupied as ofJune 30, 2021 is shown below. Unconsolidated portfolios shown below consist of assets owned by unconsolidated entities in which we have invested. We often provide management services for these entities under management agreements and receive management fees. These are shown as Managed Unconsolidated Portfolio. Entities for which we do not provide such services are shown as Non-Managed Unconsolidated Portfolio.

Net rentable square feet represents the current square feet under lease as
specified in the applicable lease agreement plus management's estimate of (1) space available for lease based on engineering drawings. The amount includes
customers' proportional share of common areas but excludes space held for the
intent of or under active development.
Space under active development includes current base building and data center
projects in progress, and excludes space held for development. For additional (2) information on the current and future investment for space under active
development, see "-Liquidity and Capital Resources of theOperating Partnership-Construction ".
Space held for development includes space held for future data center (3) development, and excludes space under active development. For additional
information on the current investment for space held for development, see
"-Liquidity and Capital Resources of theOperating Partnership-Construction ". 40 Table of Contents Leasing Activities Due to the capital-intensive and long-term nature of the operations we support, our lease terms with customers are generally longer than standard commercial leases. As ofJune 30, 2021 , our average remaining lease term was approximately five years. Our ability to re-lease expiring space at rental rates equal to or in excess of current rental rates will impact our results of operations. The following table summarizes our leasing activity in the six months endedJune 30, 2021 : TI's/Lease Weighted Commissions Average Lease Rentable Expiring New Rental Rate Per Square Terms Square Feet (1) Rates (2) Rates (2) Changes Foot (years)

For some of our properties, we calculate square footage based on factors in (1) addition to contractually leased square feet, including power, required
support space and common area.
Rental rates represent average annual estimated base cash rent per rentable
square foot - calculated for each contract based on total cash base rent (2) divided by the total number of years in the contract (including any tenant
concessions). All rates were calculated in the local currency of each
contract and then converted to USD based on average exchange rates for the
six months ended
(3) Excludes short-term leases.
(4) Commencement dates for the leases signed range from 2021 to 2022.
(5) Includes leases signed for new and re-leased space.
(6) Other includes
office space within fully improved data center facilities.
We continue to see strong demand in most of our key metropolitan areas for data center space and, subject to the supply of available data center space in these metropolitan areas, we expect average aggregate rental rates on re-leased or renewed data center leases for 2021 expirations to generally be consistent with the rates currently being paid for the same space on a GAAP basis and on a cash basis. Our past performance may not be indicative of future results, and we cannot assure you that leases will be renewed or that our data centers will be re-leased at all or at rental rates equal to or above the current average rental rates. Further, re-leased/renewed rental rates in a particular metropolitan area may not be consistent with rental rates across our portfolio as a whole and may fluctuate from one period to another due to a number of factors, including local economic conditions, local supply and demand for data center space, competition from other data center developers or operators, the condition of the property and whether the property, or space within the property, has been developed.
41 Table of Contents Geographic concentration
We depend on the market for data centers in specific geographic regions and significant changes in these regional or metropolitan areas can impact our future results. The following table shows the geographic concentration of annualized rent from our portfolio, including data centers held as investments in unconsolidated entities.

Operating expenses
Our operating expenses primarily consist of utilities, property and ad valorem taxes, property management fees, insurance and site maintenance costs, and rental expenses on our ground and building leases. Our buildings require significant power to support data center operations and the cost of electric power and other utilities is a significant component of operating expenses. Many of our leases contain provisions under which tenants reimburse us for all or a portion of property operating expenses and real estate taxes incurred by us. However, in some cases we are not entitled to reimbursement of property operating expenses, other than utility expense, and real estate taxes under our leases for Turn-Key Flex® facilities. We expect to incur additional operating expenses as we continue to expand.
Costs pertaining to our asset management function, legal, accounting, corporate governance, reporting and compliance are categorized as general and administrative costs within operating expenses.
Other key components of operating expenses include: depreciation of our fixed assets, amortization of intangible assets, and transaction and integration costs.
Other Income / (Expenses)
Equity in earnings of unconsolidated entities, interest expense, and income tax expense make up the majority of other income/(expense). Equity in earnings of unconsolidated entities represents our share of the income/(loss) of entities 42 Table of Contents
in which we invest, but do not consolidate underU.S. GAAP. The largest of these investments is currently Ascenty which is located primarily inBrazil . We also hold investments in multiple other unconsolidated entities across the globe. Given that many of these entities transact in currencies other than theU.S. Dollar, results of these entities can be significantly impacted by changes in foreign currency exchange rates. Interest expense pertains primarily to unsecured senior notes, the majority of which are issued at fixed rates. The Company is subject to foreign, state and local taxes in the jurisdictions in which it operates and income tax expense can be impacted by changes in tax rates in these various jurisdictions.
Factors Which May Influence Future Results of Operations
COVID-19. We continue to closely monitor the impact of the COVID-19 pandemic on our global business and operations, including the impact on our customers, suppliers and business partners. As of the date of this report, all of our facilities have been and continue to be fully operational and operating in accordance with our business continuity and pandemic response plans. Across our portfolio, our facilities have been deemed essential operations, allowing us to remain staffed with critical personnel in place to continue to provide services and support for our customers. While we did not experience significant disruptions from the COVID-19 pandemic during the six months endedJune 30, 2021 nor as of the date of this report, we cannot predict the impact that the COVID-19 pandemic will have on our future financial condition, results of operations and cash flows due to numerous uncertainties. Rental Income. As ofJune 30, 2021 , most of our leases (on a rentable square footage basis) contained base rent escalations that were either fixed (generally ranging from 2% to 4%) or indexed based on a consumer price index or other similar inflation-related index. We cannot assure you that these escalations will cover all the increases in our costs or will otherwise keep rental rates at or above market rates. Our ability to increase revenue depends in part on our ability to develop and lease capacity at favorable rates, which we may not be able to obtain. Significant capital investment is required in order to develop data center facilities that are ready for use and, in addition, we may require additional time or encounter delays in securing customers for development projects. We may purchase additional vacant properties and properties with vacant development capacity in the future. We will require additional capital to finance our development activities, which may not be available or may not be available on terms acceptable to us. In addition to approximately 5.0 million square feet of available space in our portfolio, which excludes approximately 7.1 million square feet of space under active development and approximately 1.0 million square feet of space held for development as ofJune 30, 2021 and the 28 data centers held as investments in our non-managed unconsolidated entities, leases representing approximately 6.5% and 13.0% of the net rentable square footage of our portfolio are scheduled to expire during the six months endingDecember 31, 2021 and the year endingDecember 31, 2022 , respectively. 43 Table of Contents Results of Operations
As a result of the consistent and significant growth in our business since the first property acquisition in 2002, we evaluate period-to-period results for revenue and property level operating expenses on a stabilized, rather than non-stabilized portfolio basis.
Stabilized: The stabilized portfolio includes properties owned as of the beginning of all periods presented with less than 5% of total rentable square feet under development.
Non-stabilized: The non-stabilized portfolio includes: 1) properties that were undergoing, or were expected to undergo, development activities during any of the periods presented, 2) any properties contributed to joint ventures, sold, or held for sale during the periods presented, and 3) any properties that were acquired or delivered at any point during the periods presented.
Comparison of the Three and Six Months Ended
Revenues Total operating revenues increased by approximately$100.2 million and$367.2 million in the three and six months endedJune 30, 2021 , respectively, compared to the same periods in 2020, driven primarily by growth in non-stabilized rental and other services revenue. Non-stabilized rental and other services revenue increased primarily due to the Interxion Combination which contributed$50.1 million and$238.9 million to the increases for the three-month and six-month periods, respectively, along with new leasing activity related to our development assets. This increase was partially offset by properties sold in 2020 and 2021. Stabilized rental and other services revenue increased$7.6 million and$23.8 million in the three and six months endedJune 30, 2021 , respectively, compared to the same periods in 2020 due to new leasing and renewals, net of expirations as well as increased tenant reimbursements associated with higher utility costs inTexas due to winter storm Uri.

Operating Expenses - Property Level
Property level operating expenses include costs to operate and maintain the locations as well as taxes and insurance. Stabilized property operating and maintenance expenses increased by approximately$15.1 million and$42.1 million in the three and six months endedJune 30, 2021 , respectively, compared to the same periods in 2020, primarily related to higher utility consumption at certain properties in the stabilized portfolio. Non-stabilized property operating and maintenance expenses increased largely due to the Interxion Combination, which contributed$22.4 million and$92.7 million to the increases for the three-month and six-month periods, respectively, primarily due to increased utility costs associated with higher business volume at Interxion properties. Leasing activity at non-stabilized properties during the twelve months endedJune 30, 2021 offset by properties sold in 2020 and 2021 also contributed to the increase.

A comparison of other operating expenses for the three and six months endedJune 30, 2021 and 2020 is shown below. The increase in all categories of other operating expenses for the 2021 periods shown is primarily driven by the Interxion Combination, which closed inMarch 2020 . The primary driver of increased other operating expenses for the three-month period endedJune 30, 2021 , as compared to the same period in 2020, was a$19.8 million increase in depreciation and amortization expense associated with additional investments in properties as part of normal growth of the business.

The term "Operating Partnership" refers toDigital Realty Trust, L.P. on a consolidated basis.
Analysis of Liquidity and Capital Resources - Parent
Our Parent does not conduct business itself, other than acting as the sole general partner of theOperating Partnership , issuing public equity from time to time, and guaranteeing certain unsecured debt of theOperating Partnership and certain of its subsidiaries and affiliates. If ourOperating Partnership or such subsidiaries fail to fulfill their debt requirements, which trigger Parent guarantee obligations, then our Parent will be required to fulfill its cash payment commitments under such guarantees. Our Parent's only material asset is its investment in ourOperating Partnership .
Our Parent's principal funding requirement is the payment of dividends on its
common and preferred stock. Our Parent's principal source of funding is the
distributions it receives from our
As the sole general partner of ourOperating Partnership , our Parent has the full, exclusive and complete responsibility for ourOperating Partnership's day-to-day management and control. Our Parent causes ourOperating Partnership to distribute such portion of its available cash as our Parent may in its discretion determine, in the manner provided in ourOperating Partnership's partnership agreement. As circumstances warrant, our Parent may issue equity from time to time on an opportunistic basis, dependent upon market conditions and available pricing. Any proceeds from such equity issuances would generally be contributed to ourOperating Partnership in exchange for additional equity interests in ourOperating Partnership . OurOperating Partnership may use the proceeds to acquire additional properties, to fund development opportunities and for general working capital purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or equity securities. Our Parent and ourOperating Partnership are parties to an at-the-market (ATM) equity offering sales agreement datedJanuary 4, 2019 , as amended in 2020 (the "Sales Agreement").

Our Parent has used and intends to use the net proceeds from the program to temporarily repay borrowings under ourOperating Partnership's global revolving credit facilities, to acquire additional properties or businesses, to fund development opportunities and for working capital and other general corporate purposes, including potentially for the repayment of other debt or the repurchase, redemption or retirement of outstanding debt securities.

We believe ourOperating Partnership's sources of working capital, specifically its cash flow from operations, and funds available under its global revolving credit facility are adequate for it to make its distribution payments to our Parent and, in turn, for our Parent to make its dividend payments to its stockholders. However, we cannot assure you that ourOperating Partnership's sources of capital will continue to be available at all or in amounts sufficient to meet its needs, including making distribution payments to our Parent. The lack of availability of capital could adversely affect ourOperating Partnership's ability to pay its distributions to our Parent, which would in turn, adversely affect our Parent's ability to pay cash dividends to its stockholders.
Future Uses of Cash - Parent
Our Parent may from time to time seek to retire, redeem or repurchase its equity or the debt securities of ourOperating Partnership or its subsidiaries through cash purchases and/or exchanges for equity securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases, redemptions or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions or other factors. The amounts involved may be material.
Dividends and Distributions - Parent
Our Parent is required to distribute 90% of its taxable income (excluding capital gains) on an annual basis to continue to qualify as a REIT for federal income tax purposes. Our Parent intends to make, but is not contractually bound to make, regular quarterly distributions to its common stockholders from cash flow from ourOperating Partnership's operating activities. While historically our Parent has satisfied this distribution requirement by making cash distributions to its stockholders, it may choose to satisfy this requirement by making distributions of cash or other property. All such distributions are at the discretion of our Parent's Board of Directors. Our Parent considers market factors and ourOperating Partnership's performance in addition to REIT requirements in determining distribution levels. Our Parent has distributed at least 100% of its taxable income annually since inception to minimize corporate level federal income taxes. Amounts accumulated for distribution to stockholders are invested primarily in interest-bearing accounts and short-term interest-bearing securities, which are consistent with our intention to maintain our Parent's status as a REIT. As a result of this distribution requirement, ourOperating Partnership cannot rely on retained earnings to fund its ongoing operations to the same extent that other companies whose parent companies are not REITs can. Our Parent may need to continue to raise capital in the debt and equity markets to fund ourOperating Partnership's working capital needs, as well as potential developments at new or existing properties, acquisitions or investments in existing or newly created joint ventures. In addition, our Parent may be required to use borrowings under theOperating Partnership's global revolving credit facility (which is guaranteed by our Parent), if necessary, to meet REIT distribution requirements and maintain our Parent's REIT status. Distributions out of our Parent's current or accumulated earnings and profits are generally classified as ordinary income whereas distributions in excess of our Parent's current and accumulated earnings and profits, to the extent of a stockholder'sU.S. federal income tax basis in our Parent's stock, are generally classified as a return of capital. Distributions in excess of a stockholder'sU.S. federal income tax basis in our Parent's stock are generally characterized as capital gain. Cash provided by operating activities has been generally sufficient to fund distributions on an annual basis. However, we may also need to utilize borrowings under the global revolving credit facility to fund distributions. 47 Table of Contents For additional information regarding dividends declared and paid by our Parent on its common and preferred stock for the six months endedJune 30, 2021 , see Note 10 to our condensed consolidated financial statements contained herein.
Analysis of Liquidity and Capital Resources - Operating Partnership
As ofJune 30, 2021 , we had$120.5 million of cash and cash equivalents, excluding$8.0 million of restricted cash. Restricted cash primarily consists of contractual capital expenditures plus other deposits. Our liquidity requirements primarily consist of: ? operating expenses,
? development costs and other expenditures associated with our properties,
? distributions to our Parent to enable it to make dividend payments,
? distributions to unitholders of common limited partnership interests inDigital Realty Trust, L.P. , ? capital expenditures, ? debt service, and, ? potentially, acquisitions. Future Uses of Cash
Our properties require periodic investments of capital for customer-related
capital expenditures and for general capital improvements. Depending upon
customer demand, we expect to incur significant improvement costs to build out
and develop additional capacity. At

Data center construction includes 7.1 million square feet of Turn Key Flex® and Powered Base Building® product. Generally, we expect to deliver the space within 12 months; however, lease commencement dates may significantly impact final delivery schedules. Equipment pool and other inventory represent the value of long-lead equipment and materials required for timely deployment and delivery of data center construction fit-out. Campus, tenant improvements and other costs include the value of development work which benefits space recently converted to our operating portfolio and is composed primarily of shared infrastructure projects and first-generation tenant improvements.
Capital Expenditures (Cash Basis)

Total capital expenditures (excluding indirect costs)
For the six months endedJune 30, 2021 , total capital expenditures increased$217.5 million to approximately$1,024.6 million from$807.1 million for the same period in 2020. Capital expenditures on our development projects 49
Table of Contents
plus our enhancement and improvements projects for the six months endedJune 30, 2021 were approximately$945.9 million , which reflects an increase of approximately 29% from the same period in 2020. This increase was primarily due to development activity at properties acquired in the Interxion Combination. Our development capital expenditures are generally funded by our available cash and equity and debt capital. Indirect costs, including capitalized interest, capitalized in the six months endedJune 30, 2021 and 2020 were$56.8 million and$47.8 million , respectively. Capitalized interest comprised approximately$23.0 million and$23.1 million of the total indirect costs capitalized for the six months endedJune 30, 2021 and 2020, respectively. Capitalized interest in the six months endedJune 30, 2021 decreased, compared to the same period in 2020, due to lower interest rates in 2021. Excluding capitalized interest, indirect costs in the six months endedJune 30, 2021 increased compared to the same period in 2020 due primarily to capitalized amounts relating to compensation expense of employees directly engaged in construction activities. See "-Future Uses of Cash" below for a discussion of the amount of capital expenditures we expect to incur during the year endingDecember 31, 2021 . Consistent with our growth strategy, we actively pursue potential acquisition opportunities, with due diligence and negotiations often at different stages at different times. The dollar value of acquisitions for the year endingDecember 31, 2021 will depend upon numerous factors, including customer demand, leasing results, availability of debt or equity capital and acquisition opportunities. Further, the growing acceptance by private institutional investors of the data center asset class has generally pushed capitalization rates lower, as such private investors may often have lower return expectations than us. As a result, we anticipate near-term single asset acquisitions activity to comprise a smaller percentage of our growth while this market dynamic persists. We may from time to time seek to retire or repurchase our outstanding debt or the equity of our Parent through cash purchases and/or exchanges for equity securities of our Parent in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend upon prevailing market conditions, our liquidity requirements, contractual restrictions or other factors. The amounts involved may be material.
Sources of Cash
We expect to meet our short-term and long-term liquidity requirements, including payment of scheduled debt maturities and funding of acquisitions and non-recurring capital improvements, with net cash from operations, future long-term secured and unsecured indebtedness and the issuance of equity and debt securities and the proceeds of equity issuances by our Parent. We also may fund future short-term and long-term liquidity requirements, including acquisitions and non-recurring capital improvements, using our global revolving credit facilities pending permanent financing. As ofAugust 4, 2021 , we had approximately$2.1 billion of borrowings available under our global revolving credit facilities. Our global revolving credit facility provides for borrowings up to$2.35 billion . We have the ability from time to time to increase the size of the global revolving credit facility by up to$1.25 billion , subject to the receipt of lender commitments and other conditions precedent. The global revolving credit facility matures onJanuary 24, 2023 , with two six-month extension options available. We have used and intend to use available borrowings under the global revolving credit facility to fund our liquidity requirements from time to time. For additional information regarding our global revolving credit facility, see Note 8 to our condensed consolidated financial statements contained herein. Subsequent toJune 30, 2021 ,Digital Intrepid Holding B.V ., an indirect wholly owned subsidiary of theOperating Partnership , issued and sold the following notes:

We intend to allocate an amount equal to the net proceeds from the offering of the Swiss Franc Notes to finance or refinance, in whole or in part, Eligible Green Projects, including the development and redevelopment of such projects. Pending the allocation of an amount equal to the net proceeds of the Swiss Franc Notes to Eligible Green Projects, all or a portion of an amount equal to the net proceeds from the Swiss Franc Notes were used to temporarily repay borrowings outstanding under theOperating Partnership's global credit facility and for other general corporate purposes.
Distributions
All distributions on our units are at the discretion of our Parent's Board of Directors. For additional information regarding distributions paid on our common and preferred units for the six months endedJune 30, 2021 , see Note 10 to our condensed consolidated financial statements contained herein.

Our ratio of debt to total enterprise value was approximately 24% (based on the closing price ofDigital Realty Trust, Inc.'s common stock onJune 30, 2021 of$150.46 ). For this purpose, our total enterprise value is defined as the sum of the market value ofDigital Realty Trust, Inc.'s outstanding common stock (which may decrease, thereby increasing our debt to total enterprise value ratio), plus the liquidation value ofDigital Realty Trust, Inc.'s preferred stock, plus the aggregate value of ourOperating Partnership's units not held byDigital Realty Trust, Inc. (with the per unit value equal to the market value of one share ofDigital Realty Trust, Inc.'s common stock and excluding long-term incentive units, Class C units and Class D units), plus the book value of our total consolidated indebtedness. The variable rate debt shown above bears interest at interest rates based on various one-month LIBOR, EURIBOR, SOR, JPY LIBOR, HIBOR, BBR and CDOR rates, depending on the respective agreement governing the debt, including our global revolving credit facilities. As ofJune 30, 2021 , our debt had a weighted average term to initial maturity of approximately 6.2 years (or approximately 6.3 years assuming exercise of extension options).
Off-Balance Sheet Arrangements
As ofJune 30, 2021 , we were party to interest rate swap agreements related to$104.0 million of outstanding principal on our variable rate debt. See Item 3. "Quantitative and Qualitative Disclosures about Market Risk." 51

Noncontrolling Interests in
Noncontrolling interests in theOperating Partnership relate to the common units in ourOperating Partnership that are not owned byDigital Realty Trust, Inc. , which, as ofJune 30, 2021 , amounted to 2.4% of ourOperating Partnership common units. Historically, ourOperating Partnership has issued common units to third party sellers in connection with our acquisition of real estate interests from such third parties. Limited partners have the right to require ourOperating Partnership to redeem part or all of their common units for cash based upon the fair market value of an equivalent number of shares ofDigital Realty Trust, Inc. common stock at the time of the redemption. Alternatively, we may elect to acquire those common units in exchange for shares ofDigital Realty Trust, Inc. common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, issuance of stock rights, specified extraordinary distributions and similar events. As ofJune 30, 2021 , approximately 0.2 million common units of theOperating Partnership that were issued to certain former unitholders ofDuPont Fabros Technology, L.P. in connection with the Company's acquisition ofDuPont Fabros Technology, Inc. were outstanding, which are subject to certain restrictions and, accordingly, are not presented as permanent capital in the condensed consolidated balance sheet.
Inflation
Many of our leases provide for separate real estate tax and operating expense escalations. In addition, many of the leases provide for fixed base rent increases. We believe that inflationary increases may be at least partially offset by the contractual rent increases and expense escalations described above.
Funds from Operations
We calculate funds from operations, or FFO, in accordance with the standards established by theNational Association of Real Estate Investment Trusts (Nareit) in the Nareit Funds From Operations White Paper - 2018 Restatement. FFO represents net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of property, a gain from a pre-existing relationship, impairment charges and real estate related depreciation and amortization (excluding amortization of deferred financing costs) and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate 53
Table of Contents
related depreciation and amortization and gains and losses from property dispositions and after adjustments for unconsolidated partnerships and joint ventures, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions, nor the level of capital expenditures and capitalized leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our financial condition and results from operations, the utility of FFO as a measure of our performance is limited. Other REITs may not calculate FFO in accordance with the Nareit definition and, accordingly, our FFO may not be comparable to other REITs' FFO. FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.
