Investment Activity
During the first quarter of 2019, Digital Realty closed the previously announced joint venture with Brookfield Infrastructure, an affiliate of Brookfield Asset Management, one of the largest owners and operators of infrastructure assets globally. Brookfield invested approximately $700 million in exchange for approximately 49% of the total equity interests in the joint venture which owns and operates Ascenty, the leading data center provider in Brazil.
During the first quarter of 2019, Digital Realty closed the previously announced 30-year ground lease with Jurong Town Council for two adjacent land parcels in Singapore totaling three acres for an upfront payment of approximately $6 million. These parcels are located less than one block from the company's existing Loyang Way data center, and are expected to support the development of up to 40 megawatts of critical power. Commencement of development will be subject to market demand and delivery will be phased to meet future growth requirements upon build-out and lease-up of the company's existing Loyang Way data center.
As previously disclosed, MC Digital Realty, a 50/50 joint venture between Mitsubishi Corporation and Digital Realty, reached an agreement during the first quarter of 2019 to acquire a five-acre land parcel in Tokyo. The site is located at the center of the Inzai data center cluster, one of the highest-density areas in Japan with a well-established utility and connectivity infrastructure, and home to leading global cloud providers and financial institutions. Demolition of the existing structure on the site will begin immediately after closing and data center development is expected to commence in 2020, subject to planning approvals. The initial facility is expected to deliver up to 35.6 megawatts of total IT capacity. The Tokyo land parcel acquisition is expected to close later this year and is subject to customary closing conditions.
Digital Realty participated in Megaport's March 2019 equity offering, investing approximately $2.6 million to maintain a 7.3% ownership stake.

(1) | Represents the purchase price before contractual purchase price adjustments, transaction expenses, taxes and potential currency fluctuations.

(2) | We calculate the cash capitalization rate on acquisitions, dispositions and joint venture contributions by dividing anticipated annual net operating income by the purchase/sale/contribution price, including assumed debt and related pre-payment penalties. Net operating income represents rental revenue and tenant reimbursement revenue from in-place leases, less rental property operating and maintenance expenses, property taxes and insurance expenses, and is not a financial measure calculated in accordance with GAAP. We caution you not to place undue reliance on our cash capitalization rates because they are based solely on data made available to us in the diligence process in connection with the relevant acquisitions and are calculated on a non-GAAP basis. Our calculation of the cash capitalization rate on acquisitions may change, based on our experience operating the data centers subsequent to closing of the acquisitions. In addition, the actual cash capitalization rates may differ from our expectations based on numerous other factors, including the results of our final purchase price allocation, difficulties collecting anticipated rental revenues, tenant bankruptcies, property tax reassessments and unanticipated expenses at the data centers that we cannot pass on to tenants.

(3) | We estimate the total net rentable square feet available for lease based on a number of factors in addition to contractually leased square feet, including available power, required support space and common area.

(4) | Occupancy excludes space under development and space held for development.

(5) | $700 million contribution by Bookfield for approximately 49% of the equity interest in the joint venture which owns and operates Ascenty, the leading data center provider in Brazil. Contribution price does not include adjustments, transaction expenses, taxes and potential currency fluctuations.

Management Statements on Non-GAAP Measures |  | Financial Supplement
Unaudited | First Quarter 2019

Definitions
Funds From Operations (FFO):
We calculate funds from operations, or FFO, in accordance with the standards established by the National Association of Real Estate Investment Trusts, or 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 real estate transactions, impairment of investment in real estate, real estate related depreciation and amortization (excluding amortization of deferred financing costs), unconsolidated JV real estate related depreciation & amortization, non-controlling interests in operating partnership and after adjustments for unconsolidated partnerships and joint ventures. Management uses FFO as a supplemental performance measure because, in excluding real estate related depreciation and amortization and gains and losses from property dispositions and after adjustments for unconsolidated partnerships and joint ventures, it provides a performance measure that, when compared year over year, captures trends in occupancy rates, rental rates and operating costs. We also believe that, as a widely recognized measure of the performance of REITs, FFO will be used by investors as a basis to compare our operating performance with that of other REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our data centers 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 data centers, 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.
Core Funds from Operations (Core FFO):
We present core funds from operations, or core FFO, as a supplemental operating measure because, in excluding certain items that do not reflect core revenue or expense streams, it provides a performance measure that, when compared year over year, captures trends in our core business operating performance. We calculate core FFO by adding to or subtracting from FFO (i) termination fees and other non-core revenues, (ii) transaction and integration expenses, (iii) loss from early extinguishment of debt, (iv) severance, equity acceleration, and legal expenses, (v) loss on FX revaluation, (vi) gain on contribution to unconsolidated joint venture, net of related tax, and (vii) other non-core expense adjustments. Because certain of these adjustments have a real economic impact on our financial condition and results from operations, the utility of core FFO as a measure of our performance is limited. Other REITs may calculate core FFO differently than we do and accordingly, our core FFO may not be comparable to other REITs' core FFO. Core FFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.
Adjusted Funds from Operations (AFFO):
We present adjusted funds from operations, or AFFO, as a supplemental operating measure because, when compared year over year, it assesses our ability to fund dividend and distribution requirements from our operating activities. We also believe that, as a widely recognized measure of the operations of REITs, AFFO will be used by investors as a basis to assess our ability to fund dividend payments in comparison to other REITs, including on a per share and unit basis. We calculate AFFO by adding to or subtracting from core FFO (i) non-real estate depreciation, (ii) amortization of deferred financing costs, (iii) amortization of debt discount/premium, (iv) non-cash stock-based compensation expense, (v) straight-line rental revenue, (vi) straight-line rental expense, (vii) above- and below-market rent amortization, (viii) deferred tax expense, (ix) leasing compensation and internal lease commissions, and (x) recurring capital expenditures. Other REITs may calculate AFFO differently than we do and accordingly, our AFFO may not be comparable to other REITs’ AFFO. AFFO should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.
EBITDA and Adjusted EBITDA:
We believe that earnings before interest, loss from early extinguishment of debt, income taxes, and depreciation and amortization, or EBITDA, and Adjusted EBITDA (as defined below), are useful supplemental performance measures because they allow investors to view our performance without the impact of non-cash depreciation and amortization or the cost of debt and, with respect to Adjusted EBITDA, severance, equity acceleration, and legal expenses, transaction and integration expenses, (gain) loss on real estate transactions, equity in earnings adjustment for non-core items, other non-core adjustments, net, noncontrolling interests, preferred stock dividends, including undeclared dividends, and issuance costs associated with redeemed preferred stock. Adjusted EBITDA is EBITDA excluding unconsolidated joint venture real estate related depreciation & amortization, severance, equity acceleration, and legal expenses, transaction and integration expenses, gain on sale / deconsolidation, impairment of investments in real estate, other non-core adjustments, net, non-controlling interests, and preferred stock dividends, including undeclared dividends. In addition, we believe EBITDA and Adjusted EBITDA are frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. Because EBITDA and Adjusted EBITDA are calculated before recurring cash charges including interest expense and income taxes, exclude capitalized costs, such as leasing commissions, and are not adjusted for capital expenditures or other recurring cash requirements of our business, their utility as a measure of our performance is limited. Other REITs may calculate EBITDA and Adjusted EBITDA differently than we do and accordingly, our EBITDA and Adjusted EBITDA may not be comparable to other REITs’ EBITDA and Adjusted EBITDA. Accordingly, EBITDA and Adjusted EBITDA should be considered only as supplements to net income computed in accordance with GAAP as a measure of our financial performance.

Net Operating Income (NOI) and Cash NOI:
Net operating income, or NOI, represents rental revenue, tenant reimbursement revenue and interconnection revenue less utilities expense, rental property operating expenses, property taxes and insurance expenses (as reflected in the statement of operations). NOI is commonly used by stockholders, company management and industry analysts as a measurement of operating performance of the company’s rental portfolio. Cash NOI is NOI less straight-line rents and above- and below-market rent amortization. Cash NOI is commonly used by stockholders, company management and industry analysts as a measure of property operating performance on a cash basis. However, because NOI and cash NOI exclude depreciation and amortization and capture neither the changes in the value of our data centers 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 data centers, all of which have real economic effect and could materially impact our results from operations, the utility of NOI and cash NOI as measures of our performance is limited. Other REITs may calculate NOI and cash NOI differently than we do and, accordingly, our NOI and cash NOI may not be comparable to other REITs’ NOI and cash NOI. NOI and cash NOI should be considered only as supplements to net income computed in accordance with GAAP as measures of our performance.
Additional Definitions
Net debt-to-Adjusted EBITDA ratio is calculated using total debt at balance sheet carrying value, plus capital lease obligations, plus our share of JV debt, less unrestricted cash and cash equivalents divided by the product of Adjusted EBITDA (inclusive of our share of JV EBITDA) multiplied by four.
Debt-plus-preferred-to-total enterprise value is mortgage debt and other loans plus preferred stock divided by mortgage debt and other loans plus the liquidation value of preferred stock and the market value of outstanding Digital Realty Trust, Inc. common stock and Digital Realty Trust, L.P. units, assuming the redemption of Digital Realty Trust, L.P. units for shares of Digital Realty Trust, Inc. common stock.
Fixed charge coverage ratio is Adjusted EBITDA divided by the sum of GAAP interest expense, capitalized interest, scheduled debt principal payments and preferred dividends. For the quarter ended March 31, 2019, GAAP interest expense was $102 million, capitalized interest was $11 million and scheduled debt principal payments and preferred dividends was $21 million.
