Forward-Looking Statements


This Quarterly Report on Form 10-Q (this "Quarterly Report"), together with
other statements and information publicly disseminated by our company, contains
certain forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995 ("PSLRA"), namely Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"). We intend such forward-looking statements to be
covered by the safe harbor provisions for forward-looking statements contained
in the PSLRA and include this statement for purposes of complying with these
safe harbor provisions.



In particular, statements pertaining to our capital resources, portfolio
performance, business strategies and results of operations contain
forward-looking statements. You can identify forward-looking statements by the
use of forward-looking terminology such as "believes," "expects," "may," "will,"
"should," "seeks," "intends," "plans," "pro forma" or "anticipates" or the
negative of these words and phrases or similar words or phrases that are
predictions of or indicate future events or trends and that do not relate solely
to historical matters. You can also identify forward-looking statements by
discussions of strategy, plans or intentions. Such statements are subject to
risks, uncertainties and assumptions and are not guarantees of future
performance, which may be affected by known and unknown risks, trends,
uncertainties and factors that are beyond our control. Should one or more of
these risks or uncertainties materialize, or should underlying assumptions prove
incorrect, actual results may vary materially from those anticipated, estimated
or projected. The following factors, among others, could cause actual results
and future events to differ materially from those set forth or contemplated in
the forward-looking statements: (i) the geographic concentration of our data
centers in certain markets and any adverse developments in local economic
conditions or the amount of supply of or demand for data center space in these
markets; (ii) fluctuations in interest rates and increased operating costs;
(iii) difficulties in identifying properties to acquire and completing
acquisitions; (iv) the significant competition in our industry, including
indirect competition from cloud service providers, and an inability to lease
vacant space, renew existing leases or release space as leases expire; (v) lack
of sufficient customer demand to realize expected returns on our investments to
expand our property portfolio; (vi) decreased revenue from costs and disruptions
associated with any failure of our physical infrastructure or services;
(vii) our ability to develop and lease available space to existing or new
customers; (viii) our failure to obtain necessary outside financing; (ix) our
ability to service existing debt; (x) our failure to qualify or maintain our
status as a real estate investment trust ("REIT"); (xi) financial market
fluctuations; (xii) changes in real estate and zoning laws and increases in real
estate taxes; (xiii) the effects on our business operations, demand for our
services and general economic conditions resulting from the "COVID-19" pandemic
in our markets, as well as orders, directives and legislative action by local,
state and federal governments in response to the COVID-19 pandemic; (xiv) delays
or disruptions in third-party network connectivity; (xv) service failures or
price increases by third party power suppliers; (xvi) inability to renew net
leases on the data center properties we lease; and (xvii) other factors
affecting the real estate or technology industries generally.



While forward-looking statements reflect our good faith beliefs, they are not
guarantees of future performance. We disclaim any obligation to publicly update
or revise any forward-looking statement to reflect changes in underlying
assumptions or factors, of new information, data or methods, future events or
other changes, except as required by applicable law. The risks included here are
not exhaustive, and additional factors could adversely affect our business and
financial performance, including factors and risks included in other sections of
this Quarterly Report, including in Item 1A. "Risk Factors" of this Quarterly
Report. Additional information concerning these and other risks and
uncertainties is contained in our other periodic filings with the United States
Securities and Exchange Commission ("SEC") pursuant to the Exchange Act. We
discussed a number of material risks in Item 1A. "Risk Factors" of our Annual
Report on   Form 10-K   for the year ended December 31, 2020. Those risks
continue to be relevant to our performance and financial condition. Given these
risks and uncertainties, investors should not place undue reliance on
forward-looking statements as a prediction of actual results.

  Table of Contents

We are engaged in the business of ownership, acquisition, construction and operation of strategically located data centers in some of the largest and fastest growing data center markets in the United States, including the San Francisco Bay area, Los Angeles, the Northern Virginia area (including Washington D.C.), the New York area, Chicago, Boston, Denver and Miami.


We deliver secure, reliable, high-performance data center, cloud access and
interconnection solutions to a growing customer ecosystem across eight key North
American communication markets. More than 1,370 customers, including many of the
world's leading enterprises, network operators, cloud providers, and supporting
service providers, choose us to connect, protect and optimize their
performance-sensitive data, applications and computing workloads.



Our focus is to bring together a network and cloud community to support the
needs of enterprises, and create a diverse customer ecosystem. Our growth
strategy includes (i) increasing cash flow from in-place data center space,
(ii) capitalizing on embedded expansion opportunities within existing data
centers, (iii) selectively pursuing acquisition and development opportunities in
existing and new markets, (iv) expanding existing customer relationships, and
(v) attracting new customers.



Our Portfolio



As of September 30, 2021, our property portfolio included 25 operating data
center facilities, office and light-industrial space and multiple potential
development projects that collectively comprise over 4.6 million net rentable
square feet ("NRSF"), of which over 2.7 million NRSF is existing data center
space. The approximately 1.5 million NRSF of development projects includes space
available for development and construction of new data center facilities. We
expect that this development potential plus any incremental investment into
existing or new markets will enable us to accommodate existing and future
customer demand and position us to continue to increase our operating cash
flows.



The following table provides an overview of our property portfolio as of
September 30, 2021:

This table presents NRSF at each market that is currently occupied or readily

available for lease as data center space and pre-stabilized data center

space. Both occupied and available data center NRSF includes a factor based

on management's estimate to account for a customer's proportionate share of (1) the required data center support space (such as the mechanical,

telecommunications and utility rooms) and building common areas, which may be

updated on a periodic basis to reflect the most current build-out of our

properties. Operating data center NRSF may require investment of Deferred

Expansion Capital (see definition on page 28).

Pre-stabilized NRSF represents projects or facilities that recently have been (2) developed and are in the initial lease-up phase. Pre-stabilized projects or


    facilities become stabilized operating properties at the earlier of
    achievement of 85% occupancy or 24 months after development completion.

"Annualized Rent" represents the monthly contractual rent under existing

commenced customer leases as of September 30, 2021, multiplied by 12. This

amount reflects total annualized base rent before any one-time or

non-recurring rent abatements and excludes power revenue, interconnection

revenue and operating expense reimbursement. We use annualized rent as a (3) supplemental performance measure because, when compared quarter over quarter

or year over year, it captures profitability of our assets. We offer this

measure because we recognize that annualized base rent will be used by

investors to compare our profitability with that of other REITs. On a gross

basis, our total portfolio annualized rent was approximately $344.3 million

as of September 30, 2021, which includes $6.8 million in operating expense


    reimbursements under modified gross and triple-net leases.

  Table of Contents

"Percent Occupied" represents customer leases that have commenced and are

occupied as of September 30, 2021. The percent occupied is determined based

on occupied square feet as a proportion of total operating NRSF as of

September 30, 2021. We use percent occupied as a supplemental performance

measure because, when compared year-over-year, it captures trends in market

demand for our assets. We offer this measure because we recognize that (4) percent occupied will be used by investors as a basis to compare our

operating performance with that of other REITs. The percent occupied for

stabilized data center space would have been 88.4%, rather than 86.2%, if all

leases signed in the current and prior periods had commenced. The percent

occupied for our total portfolio, including stabilized data center space,

pre-stabilized space and office and light-industrial space, would have been

85.3%, rather than 83.3%, if all leases signed in current and prior periods

had commenced.

Represents incremental data center capacity currently vacant in existing

facilities in our portfolio that requires significant capital investment in

order to develop into data center facilities. Includes NRSF under (5) construction for which substantial activities are ongoing to prepare the

property for its intended use following development and NRSF in

pre-construction, which are projects in the design and permitting stages. The

NRSF reflects management's estimate of engineering drawings and required

support space and is subject to change based on final demising of space.

Due to our decision to exit and vacate our leased data center space at LA4 (6) and two computer rooms at LA1 by the end of 2021, we have excluded these

leased spaces from the reported Los Angeles market operating property

portfolio.

(7) Included within our Northern Virginia market is held for development space is

49,799 NRSF that is currently operating as office and light-industrial space.

Represents space that is currently occupied or readily available for lease as (8) space other than data center space, which typically is offered for office or


    light-industrial uses.




"Same-Store" statistics are based on space within each data center facility that
was leased or available to be leased as of December 31, 2019, excluding space
for which development was completed and became available to be leased after
December 31, 2019. We track Same-Store space leased or available to be leased at
the computer room level within each data center facility. We use Same-Store
statistics as a supplemental performance measure because they provide a
performance comparison for the computer rooms that have been operating for two
years or longer. We offer this measure because we recognize that Same-Store
statistics will be used by investors as a basis to compare operating performance
of our established computer rooms, excluding the impact of new computer rooms
placed into service within the past two years, to that of other REITs. The
following table shows the September 30, 2021, Same-Store operating statistics.
For comparison purposes, the operating activity totals as of December 31, 2020,
and 2019, for this space are provided at the bottom of this table.

The percent occupied for data center space, office and light-industrial (1) space, and total space would have been 87.1%, 83.6% and 86.7%, respectively,


    if all leases signed in the current and prior periods had commenced.




Same-Store annualized rent increased to $318.9 million at September 30, 2021,
compared to $314.7 million at December 31, 2020. The increase of $4.2 million is
primarily due to the commencement of new and expansion leases at SV8 and LA2.

Represents NRSF for which substantial construction activities are ongoing to (1) prepare the property for its intended use following development. The NRSF

reflects management's estimate of engineering drawings and required support

space and is subject to change based on final demising of space.

Represents estimated incremental data center capacity currently vacant in (2) existing facilities or on vacant land in our portfolio that requires


    significant capital investment in order to develop into data center
    facilities.

The NRSF for these facilities reflect management's estimates based on our (3) current construction plans and expectations regarding entitlements. These

estimates are subject to change based on current economic conditions, final

zoning approvals, and the supply and demand dynamics of the market.

In addition to our development opportunities disclosed within this table, we

have land adjacent to our NY2 facility, in the form of an existing parking (4) lot. By utilizing this land, we believe that we could develop 100,000 NRSF on

our available acreage in Secaucus, New Jersey, upon receipt of necessary


    entitlements.

During the nine months ended September 30, 2021, we incurred approximately
$103.3 million of capital expenditures, of which approximately $77.4 million
related to data center expansion activities, including new data center
construction, the development of capacity within existing data centers and other
revenue generating investments. As we construct data center capacity, we work to
optimize both the amount of capital we deploy on power and cooling
infrastructure and the

                                       27

timing of that capital deployment. As such, we generally construct our power and
cooling infrastructure supporting our data center NRSF based on our estimate of
customer utilization. This practice can result in our investment at a later time
in "Deferred Expansion Capital". We define Deferred Expansion Capital as our
estimate of the incremental capital we may invest in the future to add power or
cooling infrastructure to support existing or anticipated future customer
utilization of NRSF within our operating data centers.



The following table sets forth capital expenditures spent during the nine months
ended September 30, 2021 for data center expansion activities, including NRSF
under construction as of September 30, 2021.

ongoing to prepare the property for its intended use following development.

Of the $6.3 million of capital expenditures spent at CH1 during the nine

(2) months ended September 30, 2021, $4.7 million relates to the acquisition of a


     parking lot adjacent to the data center property.



During the nine months ended September 30, 2021, we incurred approximately $1.9 million in non-recurring investments, of which $0.1 million was a result of internal information technology software development and the remaining $1.8 million was a result of other non-recurring investments, such as remodel or upgrade projects.


During the nine months ended September 30, 2021, we incurred approximately $7.2
million in tenant improvements, which related to tenant-specific space build-out
and power installations at various properties.



During the nine months ended September 30, 2021, we incurred approximately $16.8
million of recurring capital expenditures within our portfolio, which includes
required equipment upgrades at our various facilities that have a future
economic benefit. We incurred approximately $13.2 million of recurring capital
related to various data center spaces within our portfolio and another $3.6
million related to an office and light-industrial customer lease that commenced
in the second quarter of 2021.



Factors that May Influence our Results of Operations





A complete discussion of factors that may influence our results of operations
can be found in our Annual Report on   Form 10-K   for the year ended December
31, 2020, filed with the SEC on February 5, 2021, which is accessible on the
SEC's website at www.sec.gov.



The ongoing COVID-19 pandemic has caused severe disruption in the U.S. and
global economies, and we, our customers and vendors have been impacted to
varying degrees. As of the date of this Quarterly Report, we have not seen a
significantly adverse overall impact on the demand for data center space or on
our ability to operate our business. See Item 1A. "Risk Factors-General Risks -
Pandemics or disease outbreaks, such as the novel coronavirus ("COVID-19"), may
disrupt our business, as a result of, among other things, increased customer
defaults, increased customer bankruptcies or insolvencies, delays in the
development and lease-up of our properties, and severe disruption in the U.S.
and global economies, which may further disrupt financial markets and could
materially adversely impact our financial condition, operations, and liquidity"
in our Annual Report on   Form 10-K   for the year ended December 31, 2020.



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. We have 279 and
1,236 data center leases representing approximately 7.2% and 17.8% of the NRSF
in our

                                       28

  Table of Contents

operating property portfolio which are scheduled to expire during the remainder
of 2021 and the year ending December 31, 2022, respectively. These leases
represent current annualized rent of $30.8 million, or 9.2% of total annualized
rent, and $88.2 million, or 26.1% of total annualized rent, with annualized
rental rates of $135 per NRSF and $157 per NRSF at expiration during the
remainder of 2021 and the year ending December 31, 2022, respectively.



Results of operations may be affected by the amount of pre-stabilized properties
in our portfolio. As we placed new development projects into service, such as
LA3, SV8, CH2, and VA3 during 2020, the initial investment returns may be lower
compared to stabilized properties due to operating expenses being less dependent
on occupancy levels than revenues. We expect property operating expenses to
increase as we place new data center NRSF into service and as projects become
stabilized, we expect the investment returns to increase. During the nine months
ended September 30, 2021, we did not place additional pre-stabilized data center
space into service.



The amount of revenue generated by the properties in our portfolio depends on
several factors, including our ability to lease available unoccupied and under
construction space at attractive rental rates. As of September 30, 2021, we had
approximately 550,000 NRSF of unoccupied or under construction data center space
of which approximately 49,000 NRSF is leased with a future commencement date.



The loss of multiple significant customers could have a material adverse effect
on our results of operations because our top ten customers in the aggregate
account for 32.6% of our total operating NRSF and 40.5% of our total annualized
rent as of September 30, 2021. One of our previously reported top ten customers
had $5.1 million of annualized rent that expired at the end of the third quarter
and an additional $1.7 million will expire early in the fourth quarter of 2021,
neither of which will be renewed. We are actively working to re-lease this
space; however, there may be a period of time between the expiration of the
current customer lease and a future customer backfill during which we will not
earn revenue on this particular data center space.



The following table summarizes our leasing activity during the nine months ended
September 30, 2021:

(1) Number of leases represents each agreement with a customer; a lease agreement

could include multiple spaces and a customer could have multiple leases.

GAAP annualized rent represents the monthly average contractual rent as (2) stated on customer contracts, multiplied by 12. This amount is inclusive of

any one-time or non-recurring rent abatements and excludes power revenue,

interconnection revenue and operating reimbursement.

Total leased NRSF is determined based on contractually leased square feet, (3) including required data center support space (such as the mechanical,

telecommunications and utility rooms) and building common areas.

GAAP rental rates represent GAAP annualized rent divided by leased NRSF. We

use GAAP annualized rent and GAAP rental rates as supplemental performance (4) measures because, when compared quarter over quarter or year over year, they

provide a performance measure that captures sales volume and pricing trends.

We offer these measures because we recognize they will be used by investors

to compare our sales volume and pricing trends to those of other REITs.

GAAP rent growth represents the increase in rental rates on renewed leases (5) commencing during the period, as compared with the previous period's rental


    rates for the same space.

(6) On October 7, 2021, we signed a large scale lease at SV7 with annualized GAAP


    rent of $1.7 million and approximately 11,800 NRSF.

Operating Revenue


Operating revenue during the three months ended September 30, 2021, and 2020, was as follows (in thousands):






                                         Three Months Ended September 30,
                                            2021                  2020           $ Change     % Change
Data center revenue:

Interconnection revenue                         22,994                21,144         1,850         8.7
Total data center revenue                      161,089               151,444         9,645         6.4
Office, light-industrial and other               2,769                 2,537           232
revenue                                                                                            9.1
Total operating revenues              $        163,858      $        153,981    $    9,877         6.4 %




The increase in operating revenues was primarily due to a $7.8 million, or 6.0%,
increase in data center rental, power, and related revenue during the three
months ended September 30, 2021, compared to the 2020 period. Data center
rental, power, and related revenue increased due to the organic growth of our
customer revenue base through favorable renewals, new customer leases and lease
expansions into new and existing space, and increased power consumption by our
customers within their deployments. Most notably, data center rental, power, and
related revenue at SV8, LA3, NY2, and VA1, where we have placed into service
large contiguous data center NRSF within the last two years, has increased $3.5
million, $2.6 million, $1.6 million, and $0.8 million, respectively, compared to
the three months ended September 30, 2020. These increases were primarily due to
the commencement of large scale and hyperscale customer leases throughout the
past twelve months, which generate variable revenue growth as customers deploy
their information technology equipment and increase their power consumption.
This activity was offset partially by a customer move-out of 39,950 NRSF at SV7
during the fourth quarter of 2020 and customer service-level agreement payments
of approximately $1.1 million during the three months ended September 30, 2021,
as well as, other customer move-outs across various properties.



In addition, interconnection revenue increased $1.9 million, or 8.7%, during the
three months ended September 30, 2021, compared to the 2020 period. The increase
is primarily a result of a net increase in the volume of cross connects from new
and existing customers during the three months ended September 30, 2021, and
revenue increases resulting from customers migrating to our higher priced fiber
and logical cross connect products.

Property operating and maintenance expense increased $5.0 million, or 11.0%,
during the three months ended September 30, 2021, compared to the 2020 period,
primarily as a result of an increase in utilities expense due to increased
electricity utilization related to the commencement of new and expansion
customer leases, net of customer move-outs, and new operations at LA3.



Real estate taxes and insurance expense decreased $0.8 million, or 13.4%, during
the three months ended September 30, 2021 as compared with the 2020 period
primarily due to the recognition of a net $1.5 million property tax refund
during the three months ended September 30, 2021. This decrease was slightly
offset by the completion of LA3 Phase 1 during the three months ended December
31, 2020, which caused an increase to real estate tax assessments and insurance,
and ceased capitalization of expenses.



Depreciation and amortization expense increased $3.3 million, or 7.9%, during
the three months ended September 30, 2021, compared to the 2020 period,
primarily as a result of an increase in depreciation expense from placing LA3
Phase 1 into service during the three months ended December 31, 2020, with
approximately 50,000 NRSF and a cost basis of approximately $72.5 million.



General and administrative expense increased $1.3 million, or 12.1%, compared to
the three months ended September 30, 2020, primarily related to an increased
headcount, resulting in higher salaries and non-cash compensation, partially
offset by reduced legal expenses in the current quarter as a result of no
operating partnership unit redemptions in the current period as compared to
2020.



Rent expense increased by $0.3 million, or 3.6%, during the three months ended
September 30, 2021, compared to the 2020 period primarily due to increased
straight-line rent expense as a result of our decision to exit the LA4 property
at the end of 2021 prior to our contractual lease term date of July 2023.

Total interest expense increased $0.5 million, or 4.5%, during the three months
ended September 30, 2021, compared to the 2020 period, primarily as a result of
decreased capitalized interest due to placing LA3 Phase 1 into service during
the twelve months ended September 30, 2021. In addition, the weighted average
principal debt outstanding was $1.8 billion and $1.7 billion during the three
months ended September 30, 2021, and 2020, respectively. This increase was

offset by a decrease in our daily weighted average interest rate to 3.04% during
the three months ended September 30, 2021 from 3.19% during the three months
ended September 30, 2020.

Operating Revenue



Operating revenue during the nine months ended September 30, 2021, and 2020, was
as follows (in thousands):




                                         Nine Months Ended September 30,

The increase in operating revenues was primarily due to a $26.0 million, or
6.8%, increase in data center rental, power, and related revenue during the nine
months ended September 30, 2021, compared to the 2020 period. Data center
rental, power, and related revenue increased due to the organic growth of our
customer revenue base through favorable renewals, new customer leases and lease
expansions into new and existing space, and increased power consumption by our
customers within their deployments. Most notably, data center rental, power, and
related revenue at SV8, LA3, LA2, NY2, and VA3, where we have placed into
service large contiguous data center NRSF within the last two years, has
increased $10.0 million, $7.3 million, $4.2 million, $3.9 million, and $3.0
million, respectively, compared to the nine months ended September 30, 2020.
These increases were primarily due to the commencement of large scale and
hyperscale customer leases throughout the past twelve months, which generate
variable revenue growth as customers deploy their information technology
equipment and increase their power consumption. This activity was offset
partially by a customer move-out of 39,950 NRSF at SV7 during the fourth quarter
of 2020 and customer service-level agreement payments of approximately $2.0
million during the nine months ended September 30, 2021, as well as, other
customer move-outs across various properties.



In addition, interconnection revenue increased $5.6 million, or 9.1%, during the
nine months ended September 30, 2021, compared to the 2020 period. The increase
is primarily a result of a net increase in the volume of cross connects from new
and existing customers during the nine months ended September 30, 2021, and
revenue increases resulting from customers migrating to our higher priced fiber
and logical cross connect products.

Property operating and maintenance expense increased $12.3 million, or 9.8%,
during the nine months ended September 30, 2021, compared to the 2020 period,
primarily as a result of an increase in utilities expense due to increased
customer electricity utilization related to the commencement of new and
expansion leases, net of customer move-outs, and new operations at SV8, CH2, and
LA3, as well as, increased costs related to building out customer requirements
for their data center deployments.



Real estate taxes and insurance expense increased $1.1 million, or 6.5%, during
the nine months ended September 30, 2021 as compared with the 2020 period,
primarily due to the completion of CH2 Phase 1, SV8 Phase 3, and LA3 Phase 1
during the year ended December 31, 2020, which caused an increase to real estate
tax assessments and insurance, and ceased capitalization of expenses. This
increase was offset by the recognition of a net $1.5 million property tax refund
during the nine months ended September 30, 2021.



Depreciation and amortization expense increased $10.5 million, or 8.5%, during
the nine months ended September 30, 2021, compared to the 2020 period, primarily
as a result of recognizing a full nine months of depreciation expense related to
the development projects completed throughout 2020, including CH2 Phase 1, SV8
Phase 3, and LA3 Phase 1. These projects comprised approximately 157,000 NRSF
placed into service with a cost basis of approximately $196.9 million.



General and administrative expense increased $1.7 million, or 5.2%, compared to
the nine months ended September 30, 2020, primarily related to increased
headcount, resulting in higher salaries and non-cash compensation, partially
offset by savings from reduced legal expenses related to operating partnership
unit redemptions during 2020, and reduced travel and events due to the COVID-19
pandemic.



Rent expense increased by $1.0 million, or 3.8%, during the nine months ended
September 30, 2021, compared to the 2020 period, primarily due to increased
straight-line rent expense as a result of our decision to exit the LA4 property
at the end of 2021 prior to our contractual lease term date of July 2023.



Other Income



Other income was $3.1 million during the nine months ended September 30, 2021 as
the result of a one-time benefit recorded due to the release of a tax liability
that is no longer expected to be incurred. There was no other income during

the
2020 period.

Percent capitalized                               18.6 %                23.1 %




Total interest expense increased $2.8 million, or 8.6%, during the nine months
ended September 30, 2021, compared to the 2020 period, primarily as a result of
decreased capitalized interest due to placing CH2 Phase 1, SV8 Phase 3, and LA3
Phase 1 into service during the twelve months ended December 31, 2020. In
addition, the weighted average principal debt outstanding was $1.8 billion and
$1.7 billion during the nine months ended September 30, 2021, and 2020,
respectively. This increase was partially offset by a decrease in our daily
weighted average interest rate to 3.06% during the nine months ended September
30, 2021 from 3.23% during the nine months ended September 30, 2020.



Liquidity and Capital Resources





Discussion of Cash Flows


Nine Months Ended September 30, 2021, Compared to the Nine Months Ended September 30, 2020





Operating Activities



Net cash provided by operating activities was $206.8 million for the nine months
ended September 30, 2021, compared to $194.8 million for the nine months ended
September 30, 2020. The increase of $12.0 million, or 6.2%, was driven by
organic growth of our operating cash flows as a result of leasing activity
within spaces recently placed into service, including SV8 Phase 3 and LA3 Phase
1, and at our LA2 and VA3 data centers. The increase was partially offset by the
timing of vendor payments and customer receipts.



Investing Activities



Net cash used in investing activities decreased by $133.7 million, or 59.7%, to
$90.4 million for the nine months ended September 30, 2021, compared to
$224.1 million for the nine months ended September 30, 2020. This decrease was
primarily due to lower construction expenditures after placing SV8 Phase 3, CH2
Phase 1, and LA3 Phase 1 into service during the year ended December 31, 2020.



Financing Activities


Net cash used in financing activities was $118.6 million during the nine months ended September 30, 2021, compared to $29.1 million provided by financing activities during the nine months ended September 30, 2020.


During the nine months ended September 30, 2021, we received cash proceeds, net
of payments, of $63.5 million from borrowings under the revolving credit
facility. During the nine months ended September 30, 2020, we received cash
proceeds, net of payments, of $57.5 million from borrowings under the revolving
credit facility.


During the nine months ended September 30, 2020, we received $150.0 million of cash proceeds from the issuance of the 2027 senior unsecured notes.





We paid $182.1 million in dividends and distributions on our common stock and
Operating Partnership units during the nine months ended September 30, 2021,
compared to $177.6 million during the nine months ended September 30, 2020, as a
result of an increase in our quarterly dividend to $3.73 per share or unit paid
during the nine months ended September 30, 2021, from $3.66 per share or unit
paid during the nine months ended 2020.

Analysis of Liquidity and Capital Resources





We have an effective shelf registration statement that allows us to offer for
sale various unspecified classes of equity and debt securities. As circumstances
warrant, we may issue debt and/or equity securities from time to time on an
opportunistic basis, dependent upon market conditions and available pricing. We
make no assurance that we can issue and sell such securities on acceptable

terms
or at all.



Our short-term liquidity requirements primarily consist of funds needed for
interest expense, operating costs, including utilities, site maintenance costs,
real estate and personal property taxes, insurance, rental expenses, sales and
marketing and general and administrative expenses, certain capital expenditures,
including for the development of data center space, discussed below, and future
distributions to common stockholders and holders of our common Operating
Partnership units during the next twelve months.



Our anticipated capital investment over the next twelve months includes the remaining estimated capital expenditures required to fund our current expansion projects under construction as of September 30, 2021, shown in the table below:






                                                                         Costs (in thousands)

We expect to meet our short-term liquidity requirements, including our
anticipated development activity over the next twelve months, primarily through
net cash on hand, cash provided by operations, and borrowing on our revolving
credit facility. As of September 30, 2021, we had $231.9 million available for
us to borrow under our revolving credit facility. In addition, we anticipate
addressing our April 2022 Term Loan maturity within the next three to six
months. Timing, pricing, and the type of debt is dependent on market conditions.
We provide no assurances that we can access the debt capital markets on
acceptable terms or at all.



Our long-term liquidity requirements primarily consist of the costs to fund the
Reston Campus Expansion, the ground up construction of new data center
buildings, Deferred Expansion Capital, additional phases of our current projects
held for development, future development of other space in our portfolio not
currently scheduled, property acquisitions, future distributions to common
stockholders and holders of our common Operating Partnership units, scheduled
debt maturities and other capital expenditures. We expect to meet our long-term
liquidity requirements through net cash provided by operations, and by incurring
long-term indebtedness, such as drawing on our revolving credit facility,
exercising our senior unsecured term loan accordion features or entering into
new debt agreements with our bank group or existing and new accredited
investors. We also may raise capital in the future through the issuance of
additional equity or debt securities, subject to prevailing market conditions,
and/or through the issuance of common Operating Partnership units. However,
there is no assurance that we will be able to successfully raise additional
capital on acceptable terms or at all.



On March 5, 2021, the Financial Conduct Authority ("FCA") announced that USD
LIBOR will no longer be published after June 30, 2023. This announcement has
several implications, including setting the spread that may be used to
automatically convert contracts from LIBOR to the Secured Overnight Financing
Rate ("SOFR"), which the Alternative Reference Rates Committee ("ARRC") and the
Internal Swaps and Derivatives Association ("ISDA") have both identified as the
preferred alternative rate for USD-LIBOR. Additionally, banking regulators are
encouraging banks to discontinue new LIBOR debt issuances by December 31, 2021.



While we expect LIBOR to be available in substantially its current form until at
least the end of June 30, 2023, it is possible that LIBOR will become
unavailable prior to that point. In the event that USD-LIBOR is not available,
each of our financial instrument contracts contain fallback provisions to
determine the applicable replacement base rate. We anticipate managing the
transition to an alternative rate using the language set out in our agreements
and through potentially modifying our debt and derivative instruments. However,
future market conditions may not allow immediate implementation of our desired
modifications and we may incur significant associated costs in doing so. We will
continue to monitor and evaluate the potential impact any such event could have
on our financial results. As of September 30, 2021, we have $912.0 million of
USD-LIBOR based variable-rate debt and $700.0 million of notional derivative
contracts.

As of September 30, 2021, we were in compliance with the financial covenants
under our revolving credit facility, senior unsecured term loans and senior
unsecured notes. For additional information with respect to our outstanding
indebtedness as of September 30, 2021, and December 31, 2020, as well as the
available borrowing capacity under our existing revolving credit facility, debt
covenant requirements, and future debt maturities, refer to Note 7 Debt, to the
condensed consolidated financial statements.



Funds From Operations



We consider funds from operations ("FFO"), a non-generally accepted accounting
principles ("GAAP") measure, to be a supplemental measure of our performance
which should be considered along with, but not as an alternative to, net income
and cash provided by operating activities as a measure of operating performance.
We calculate FFO in accordance with the standards established by the National
Association of Real Estate Investment Trusts ("Nareit"). Nareit defined FFO
represents net income (computed in accordance with GAAP), excluding gains (or
losses) from sales of property and undepreciated land and impairment write-downs
of depreciable real estate, plus real estate related depreciation and
amortization (excluding amortization of deferred financing costs) and after
adjustments for unconsolidated partnerships and joint ventures. During the three
and nine months ended September 30, 2021, we reported FFO, as adjusted, which
excludes from FFO a one-time, non-cash benefit of $3.1 million as a result of
the release of a tax liability during the second quarter of 2021 that is no
longer expected to be incurred.



We use FFO as a supplemental performance measure because, in excluding real
estate related depreciation and amortization and gains and losses from property
dispositions, it provides a performance measure that, when compared year over
year, captures trends in occupancy rates, rental rates and operating costs.



We offer this measure because we recognize that FFO will be used by investors as
a basis to compare our operating performance with that of other REITs. However,
because FFO excludes real estate related 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. FFO is a non-GAAP measure and should not
be considered a measure of liquidity, an alternative to net income, cash
provided by operating activities or any other

performance measure determined in accordance with GAAP, nor is it indicative of
funds available to fund our cash needs, including our ability to pay dividends
or make distributions. In addition, our calculations of FFO are not necessarily
comparable to FFO as calculated by other REITs that do not use the same
definition or implementation guidelines or interpret the Nareit standards
differently from us. Investors in our securities should not rely on these
measures as a substitute for any GAAP measure, including net income. The
following table provides a reconciliation of our net income to FFO (in
thousands, except per share data):

Distribution Policy



In order to comply with the REIT requirements of the Code, we generally are
required to make annual distributions to our stockholders of at least 90% of our
net taxable income. Our common stock distribution policy is to distribute as
dividends, at a minimum, a percentage of our cash flow that ensures that we will
meet the distribution requirements of the Code and any subsequent increases
and/or anticipated increases are correlated to increases in our growth of cash
flow.



We have made distributions every quarter since the completion of our initial
public offering in 2010. During the nine months ended September 30, 2021, we
declared three quarterly dividends totaling $3.77 per share of common stock and
Operating Partnership unit. While we plan to continue to make quarterly
distributions, no assurances can be made as to the frequency or amounts of any
future distributions. The payment of common stock distributions is dependent
upon, among other things, restriction in agreements governing out indebtedness,
our financial condition, operating results and REIT distribution requirements
and may be adjusted at the discretion of our Board of Directors during the year.



The following table summarizes the taxability of our common stock dividends per share for the years ended December 31, 2020, and 2019:
