Overview

During the six months ended June 30, 2021, we:



•finished the period with our office and data center shell portfolio 93.5%
occupied and 94.3% leased;
•placed into service 243,000 square feet in four newly-developed office
properties that were 77.7% leased as of June 30, 2021;
•refinanced certain unsecured senior notes issuances with a new unsecured senior
note issuance by:
•issuing $600.0 million of 2.75% Notes at an initial offering price of 98.95% of
their face value on March 11, 2021. The proceeds from this issuance, after
deducting underwriting discounts but before other offering expenses, were
$589.8 million; and
•purchasing or redeeming $350.0 million of 3.60% Notes (52.7% of such notes
effective March 11, 2021 and the remaining notes on April 12, 2021) and $250.0
million of 5.25% Notes (58.2% of such notes effective March 11, 2021 and the
remaining notes on April 12, 2021) for $373.1 million and $282.4 million,
respectively, plus accrued interest. In connection with these purchases, we
recognized a loss on early extinguishment of debt in the three months and six
months ended June 30, 2021 of $25.2 million and $58.4 million, respectively.
We used borrowings under our Revolving Credit Facility to fund the net cash
outlay resulting from this refinancing; and
•sold a 90% interest in two data center shell properties in Northern Virginia on
June 2, 2021 based on an aggregate property value of $118.8 million and retained
a 10% interest in the properties through B RE COPT DC JV III LLC, a newly-formed
joint venture. Our partner in the joint venture acquired the 90% interest from
us for $106.9 million, which was used by us to repay borrowings under our
Revolving Credit Facility.

With regard to our operating portfolio square footage, occupancy and leasing
statistics included below and elsewhere in this Quarterly Report on Form 10-Q,
amounts disclosed include information pertaining to properties owned through
unconsolidated real estate joint ventures.

We discuss significant factors contributing to changes in our net income in the
section below entitled "Results of Operations." In addition, the section below
entitled "Liquidity and Capital Resources" includes discussions of, among other
things:

•how we expect to generate cash for short and long-term capital needs; and •our commitments and contingencies.

forward-looking statements are based on reasonable assumptions at the time made,
we can give no assurance that these expectations, estimates and projections will
be achieved. Future events and actual results may differ materially from those
discussed in the forward-looking statements. Important factors that may affect
these expectations, estimates and projections include, but are not limited to:

affect office property and data center demand and rents, tenant
creditworthiness, interest rates, financing availability, construction costs and
property values;

similar pandemics, along with restrictive measures instituted to prevent spread,
on our business, the real estate industry and national, regional and local
economic conditions;
•governmental actions and initiatives, including risks associated with the
impact of a prolonged government shutdown or budgetary reductions or impasses,
such as a reduction in rental revenues, non-renewal of leases and/or reduced or
delayed demand for additional space by our strategic customers;
•our ability to borrow on favorable terms;
                                       30
--------------------------------------------------------------------------------

•risks of real estate acquisition and development activities, including, among
other things, risks that development projects may not be completed on schedule,
that tenants may not take occupancy or pay rent or that development or operating
costs may be greater than anticipated;
•risks of investing through joint venture structures, including risks that our
joint venture partners may not fulfill their financial obligations as investors
or may take actions that are inconsistent with our objectives;
•changes in our plans for properties or views of market economic conditions or
failure to obtain development rights, either of which could result in
recognition of significant impairment losses;
•our ability to satisfy and operate effectively under Federal income tax rules
relating to real estate investment trusts and partnerships;
•possible adverse changes in tax laws;
•the dilutive effects of issuing additional common shares;
•our ability to achieve projected results;

Effects of COVID-19



As of the date of this filing, spread of the coronavirus, or COVID-19, continues
world- and nation-wide. To date, the United States has made significant progress
with the pandemic relative to the beginning of the year, with significantly
lower new case volumes and a significant increase in the proportion of the
population that has been vaccinated. With this progress, most restrictive
measures previously instituted to control spread have been gradually lifted and
an increasing proportion of the population has resumed a return to normal
activities. However, there continues to be significant uncertainty regarding the
duration and extent of the pandemic due to factors such as the continuing spread
of the virus (including recent increases in new case volumes in much of the
United States), the pace of vaccination efforts (including potential future
booster shots) and vaccine efficacy in terms of duration and against variants of
the virus.

While the pandemic has impacted the operations of much of the commercial real
estate industry, we believe that we have been less susceptible to such impact
due to our portfolio's significant concentration in Defense/IT Locations. As a
result, our results of operations were not significantly affected by the
pandemic. For the three and six months ended June 30, 2021, our:

•Same Properties NOI from real estate operations increased for the three and six
months ended June 30, 2021 relative to the comparable 2020 periods by $2.1
million and $1.1 million, respectively, and was only minimally affected by the
pandemic-related net effect of lower provisions for collectability losses,
offset in part by lower parking revenue, in the 2021 periods relative to the
2020 periods; and
•lease revenue collections were not significantly affected by the pandemic.
After agreeing to deferred payment arrangements for approximately $2.6 million
in lease receivables last year (most of which was repaid by June 30, 2021), we
did not agree to significant additional arrangements to date in 2021.

While we do not currently expect that the pandemic will significantly affect our
future results of operations, financial condition or cash flows, we believe that
the impact will be dependent on future developments, including the duration and
extent of the pandemic, the prevalence, strength and duration of restrictive
measures and the resulting effects on our tenants, potential future tenants, the
commercial real estate industry and the broader economy, all of which are
uncertain and difficult to predict. Nevertheless, we believe at this time that
there is more inherent risk associated with the operations of our Regional
Office properties than our Defense/IT Locations.

While we do not believe that our development leasing and ability to renew leases
scheduled to expire have been significantly affected by the pandemic, we do
believe that the impact of the restrictive measures and the economic uncertainty
caused by the pandemic has impacted our timing and volume of vacant space
leasing, and may continue to do so in the future.

The pandemic enhances the risk of us being able to stay on pace to complete
development and begin operations on schedule due to the potential for delays
from: jurisdictional permitting and inspections; factories' ability to provide
materials; and possible labor shortages. These types of issues have not
significantly affected us to date but could in the future, depending on pandemic
related developments.

We do not expect that we will be required to incur significant additional capital expenditures on existing properties as a result of the pandemic.

During the six months ended June 30, 2021, we completed 1.7 million square feet
of leasing, including: renewed leases on 815,000 square feet, representing 78.3%
of the square footage of our lease expirations (including the effect of early
renewals and excluding vacated space removed from service for
redevelopment); 205,000 square feet of vacant space; and 641,000 square feet of
development space.

Wholesale Data Center

Our 19.25 megawatt wholesale data center was 86.7% leased as of June 30, 2021 and December 31, 2020. An 11.25 megawatt lease that expired in August 2020 remains in place until renewed by both parties or terminated by either party.

Results of Operations



We evaluate the operating performance of our properties using NOI from real
estate operations, our segment performance measure, which includes: real estate
revenues and property operating expenses; and the net of revenues and property
operating expenses of real estate operations owned through unconsolidated real
estate joint ventures ("UJVs") that is allocable to our ownership interest ("UJV
NOI allocable to COPT").  We view our NOI from real estate operations as
comprising the following primary categories:

•office and data center shell properties: •stably owned and 100% operational throughout the current and prior year reporting periods being compared. We define these as changes from "Same Properties";


                                       32
--------------------------------------------------------------------------------

•developed or redeveloped and placed into service that were not 100% operational
throughout the current and prior year reporting periods; and
•disposed; and
•our wholesale data center.

In addition to owning properties, we provide construction management and other
services. The primary manner in which we evaluate the operating performance of
our construction management and other service activities is through a measure we
define as NOI from service operations, which is based on the net of the revenues
and expenses from these activities.  The revenues and expenses from these
activities consist primarily of subcontracted costs that are reimbursed to us by
customers along with a management fee.  The operating margins from these
activities are small relative to the revenue.  We believe NOI from service
operations is a useful measure in assessing both our level of activity and our
profitability in conducting such operations.

Since both of the measures discussed above exclude certain items includable in
net income, reliance on these measures has limitations; management compensates
for these limitations by using the measures simply as supplemental measures that
are considered alongside other GAAP and non-GAAP measures. A reconciliation of
NOI from real estate operations and NOI from service operations to net income
reported on our consolidated statements of operations is provided in Note 14 to
our consolidated financial statements.

Our Same Properties pool consisted of 158 properties, comprising 81.9% of our
office and data center shell portfolio's square footage as of June 30, 2021.
This pool of properties changed from the pool used for purposes of comparing
2020 and 2019 in our 2020 Annual Report on Form 10-K due to the: addition of
eight properties placed in service and 100% operational
                                       34

on or before January 1, 2020 and nine properties owned through an unconsolidated
real estate joint venture that was formed in 2019; and removal of two properties
in which we sold a 90% interest and one property reclassified as redevelopment.

Regarding the changes in NOI from real estate operations reported above:



•the increase for our Same Properties pool was due primarily to lower provisions
for collectability losses and higher lease termination revenue in the current
period;
•developed and redeveloped properties placed in service reflects the effect of
15 properties placed in service in 2020 and 2021; and
•dispositions, net of retained interest in newly-formed UJVs reflects the effect
of our decrease in ownership of eight data center shells in 2020 and two in
2021.

Construction contract and other service revenue and expenses increased due primarily to a higher volume of construction activity in connection with several of our tenants. Construction contract activity is inherently subject to significant variability depending on the volume and nature of projects undertaken by us primarily on behalf of tenants. Service operations are an ancillary component of our overall operations that typically contribute an insignificant amount of income relative to our real estate operations.

Depreciation and amortization associated with real estate operations

The increase in depreciation and amortization associated with real estate operations was mostly attributable to newly-developed properties placed in service.

Gain on sales of real estate

The gain on sales of real estate was due to our sale of a 90% interest in two data center shell properties in the current period.

Loss on extinguishment of debt



The loss on early extinguishment of debt recognized in the current period was
attributable to our redemption of the remaining 3.60% Notes and 5.25% Notes in
the current period.

Regarding the changes in NOI from real estate operations reported above:



•the increase for our Same Properties pool was due primarily to: higher rent per
occupied square foot in the current period due to an increase in rental rates
(mostly from leases of renewed or previously-vacant space) and lower provisions
for
                                       37

collectability losses; and higher lease termination revenue in the current
period; offset in part by higher snow removal costs and lower parking revenue in
the current period;
•developed and redeveloped properties placed in service reflects the effect of
15 properties placed in service in 2020 and 2021; and
•dispositions, net of retained interest in newly-formed UJVs reflects the effect
of our decrease in ownership of eight data center shells in 2020 and two in
2021.

$ 1,085 $ 586

Construction contract and other service revenue and expenses increased due primarily to a higher volume of construction activity in connection with several of our tenants.

Depreciation and amortization associated with real estate operations

The increase in depreciation and amortization associated with real estate operations was mostly attributable to newly-developed properties placed in service.

Gain on sales of real estate

The gain on sales of real estate was due to our sale of a 90% interest in two data center shell properties in the current period.

Loss on extinguishment of debt

The loss on early extinguishment of debt recognized in the current period was attributable to our purchase and redemption of 3.60% Notes and 5.25% Notes.

Funds from Operations



Funds from operations ("FFO") is defined as net income computed using GAAP,
excluding gains on sales and impairment losses of real estate (net of associated
income tax) and real estate-related depreciation and amortization. FFO also
includes adjustments to net income for the effects of the items noted above
pertaining to UJVs that were allocable to our ownership interest in the UJVs. We
believe that we use the National Association of Real Estate Investment Trusts
("Nareit") definition of FFO, although others may interpret the definition
differently and, accordingly, our presentation of FFO may differ from those of
other REITs.  We believe that FFO is useful to management and investors as a
supplemental measure of operating performance because, by excluding gains on
sales and impairment losses of real estate and investments in unconsolidated
real estate joint ventures (net of associated income tax), and real
estate-related depreciation and amortization, FFO can help one compare our
operating performance between periods.  In addition, since most equity REITs
provide FFO information to the investment community, we believe that FFO is
useful to investors as a supplemental measure for comparing our results to those
of other equity REITs.  We believe that net income is the most directly
comparable GAAP measure to FFO.

Since FFO excludes certain items includable in net income, reliance on the
measure has limitations; management compensates for these limitations by using
the measure simply as a supplemental measure that is weighed in balance with
other GAAP and non-GAAP measures. FFO is not necessarily an indication of our
cash flow available to fund cash needs.  Additionally, it should not be used as
an alternative to net income when evaluating our financial performance or to
cash flow from operating, investing and financing activities when evaluating our
liquidity or ability to make cash distributions or pay debt service.

Basic FFO available to common share and common unit holders ("Basic FFO") is FFO
adjusted to subtract (1) preferred share dividends, (2) income attributable to
noncontrolling interests through ownership of preferred units in the Operating
Partnership or interests in other consolidated entities not owned by us,
(3) depreciation and amortization allocable to noncontrolling interests in other
consolidated entities and (4) Basic FFO allocable to share-based compensation
awards.  With
                                       38
--------------------------------------------------------------------------------

these adjustments, Basic FFO represents FFO available to common shareholders and
common unitholders.  Common units in the Operating Partnership are substantially
similar to our common shares and are exchangeable into common shares, subject to
certain conditions.  We believe that Basic FFO is useful to investors due to the
close correlation of common units to common shares.  We believe that net income
is the most directly comparable GAAP measure to Basic FFO.  Basic FFO has
essentially the same limitations as FFO; management compensates for these
limitations in essentially the same manner as described above for FFO.

Diluted FFO available to common share and common unit holders ("Diluted FFO") is
Basic FFO adjusted to add back any changes in Basic FFO that would result from
the assumed conversion of securities that are convertible or exchangeable into
common shares.  We believe that Diluted FFO is useful to investors because it is
the numerator used to compute Diluted FFO per share, discussed below.  We
believe that net income is the most directly comparable GAAP measure to Diluted
FFO.  Since Diluted FFO excludes certain items includable in the numerator to
diluted EPS, reliance on the measure has limitations; management compensates for
these limitations by using the measure simply as a supplemental measure that is
weighed in the balance with other GAAP and non-GAAP measures.  Diluted FFO is
not necessarily an indication of our cash flow available to fund cash needs.
Additionally, it should not be used as an alternative to net income when
evaluating our financial performance or to cash flow from operating, investing
and financing activities when evaluating our liquidity or ability to make cash
distributions or pay debt service.

Diluted FFO available to common share and common unit holders, as adjusted for
comparability is defined as Diluted FFO adjusted to exclude: operating property
acquisition costs; gain or loss on early extinguishment of debt; FFO associated
with properties securing non-recourse debt on which we have defaulted and which
we have extinguished, or expect to extinguish, via conveyance of such
properties, including property NOI, interest expense and gains on debt
extinguishment (discussed further below); loss on interest rate derivatives;
demolition costs on redevelopment and nonrecurring improvements; executive
transition costs; issuance costs associated with redeemed preferred shares;
allocations of FFO to holders on noncontrolling interests resulting from capital
events; and certain other expenses that we believe are not closely correlated
with our operating performance.  This measure also includes adjustments for the
effects of the items noted above pertaining to UJVs that were allocable to our
ownership interest in the UJVs. We believe this to be a useful supplemental
measure alongside Diluted FFO as it excludes gains and losses from certain
investing and financing activities and certain other items that we believe are
not closely correlated to (or associated with) our operating performance. We
believe that net income is the most directly comparable GAAP measure to this
non-GAAP measure.  This measure has essentially the same limitations as Diluted
FFO, as well as the further limitation of not reflecting the effects of the
excluded items; we compensate for these limitations in essentially the same
manner as described above for Diluted FFO.

Diluted FFO per share is (1) Diluted FFO divided by (2) the sum of the
(a) weighted average common shares outstanding during a period, (b) weighted
average common units outstanding during a period and (c) weighted average number
of potential additional common shares that would have been outstanding during a
period if other securities that are convertible or exchangeable into common
shares were converted or exchanged.  We believe that Diluted FFO per share is
useful to investors because it provides investors with a further context for
evaluating our FFO results in the same manner that investors use earnings per
share ("EPS") in evaluating net income available to common shareholders.  In
addition, since most equity REITs provide Diluted FFO per share information to
the investment community, we believe that Diluted FFO per share is a useful
supplemental measure for comparing us to other equity REITs. We believe that
diluted EPS is the most directly comparable GAAP measure to Diluted FFO per
share. Diluted FFO per share has most of the same limitations as Diluted FFO
(described above); management compensates for these limitations in essentially
the same manner as described above for Diluted FFO.

Diluted FFO per share, as adjusted for comparability is (1) Diluted FFO, as
adjusted for comparability divided by (2) the sum of the (a) weighted average
common shares outstanding during a period, (b) weighted average common units
outstanding during a period and (c) weighted average number of potential
additional common shares that would have been outstanding during a period if
other securities that are convertible or exchangeable into common shares were
converted or exchanged.  We believe that this measure is useful to investors
because it provides investors with a further context for evaluating our FFO
results.  We believe this to be a useful supplemental measure alongside Diluted
FFO per share as it excludes gains and losses from certain investing and
financing activities and certain other items that we believe are not closely
correlated to (or associated with) our operating performance. We believe that
diluted EPS is the most directly comparable GAAP measure to this per share
measure.  This measure has most of the same limitations as Diluted FFO
(described above) as well as the further limitation of not reflecting the
effects of the excluded items; we compensate for these limitations in
essentially the same manner as described above for Diluted FFO.

The computations for all of the above measures on a diluted basis assume the
conversion of common units in COPLP but do not assume the conversion of other
securities that are convertible into common shares if the conversion of those
securities would increase per share measures in a given period.

Property Additions

The table below sets forth the major components of our additions to properties for the six months ended June 30, 2021 (in thousands): Development

$  96,308

Tenant improvements on operating properties (1) 12,275 Capital improvements on operating properties 10,398

$ 118,981

(1)Tenant improvement costs incurred on newly-developed properties are classified in this table as development and redevelopment.

Cash Flows



Net cash flow from operating activities increased $1.5 million when comparing
the six months ended June 30, 2021 and 2020 due to an increase in cash flow from
real estate operations resulting from the growth of our property portfolio,
which was partially offset by a decrease associated with the timing of cash flow
from third-party construction projects.

Net cash flow used in investing activities decreased $196.7 million when
comparing the six months ended June 30, 2021 and 2020 due primarily to $114.4
million in property disposition proceeds mostly from our sale in 2021 of a 90%
interest in two data center shells and a $74.4 million decrease in cash outlays
for development and redevelopment of properties.

Net cash flow used in financing activities in the six months ended June 30, 2021 was $107.7 million, and included the following:



•net cash outlays from debt borrowings of $37.4 million, which included the net
decrease from our purchase and redemption of 3.60% Notes and 5.25% Notes (and

•net proceeds from debt borrowings of $179.3 million; offset in part by •dividends to common shareholders of $61.7 million.

Supplemental Guarantor Information



As of June 30, 2021, COPLP had several series of unsecured senior notes
outstanding that were issued in transactions registered with the SEC under the
Securities Act of 1933, as amended. These notes are COPLP's direct, senior
unsecured and unsubordinated obligations and rank equally in right of payment
with all of COPLP's existing and future senior unsecured and unsubordinated
indebtedness. However, these notes are effectively subordinated in right of
payment to COPLP's existing and future secured indebtedness. The notes are also
effectively subordinated in right of payment to all existing and future
liabilities and other indebtedness, whether secured or unsecured, of COPLP's
subsidiaries. COPT fully and unconditionally guarantees COPLP's obligations
under these notes. COPT's guarantees of these notes are senior unsecured
obligations that rank equally in right of payment with other senior unsecured
obligations of, or guarantees by, COPT. COPT itself does not hold any
indebtedness, and its only material asset is its investment in COPLP.

In March 2020, the SEC adopted amendments to Rule 3-10 of Regulation S-X and
adopted Rule 13-01 of Regulation S-X to simplify disclosure requirements related
to certain registered securities that became effective on January 4, 2021. As a
result of these amendments, subsidiary issuers of obligations guaranteed by the
parent are not required to provide separate financial statements, provided that
the subsidiary obligor is consolidated into the parent company's consolidated
financial statements, the parent guarantee is "full and unconditional" and the
alternative disclosure required by Rule 13-01 is provided, which includes
narrative disclosure and, subject to certain exceptions, summarized financial
information. Accordingly, we no longer present separate consolidated financial
statements for the Operating Partnership. Furthermore, as permitted under Rule
13-01(a)(4)(vi), we have excluded summarized financial information for the
Operating Partnership since: the assets, liabilities, and results of operations
of the Company and the Operating Partnership are not materially different than
the corresponding amounts presented in the consolidated financial statements of
the Company; and we believe that inclusion of such summarized financial
information would be repetitive and not provide incremental value to investors.

Liquidity and Capital Resources



Our primary cash requirements are for operating expenses, debt service,
development of new properties, improvements to existing properties and dividends
to our shareholders.  We expect to continue to use cash flow provided by
operations as the primary source to meet our short-term capital needs, including
property operating expenses, general and administrative expenses, interest
expense, scheduled principal amortization of debt, dividends to our
shareholders, distributions to COPLP's unitholders and improvements to existing
properties.  As of June 30, 2021, we had $17.2 million in cash and cash
equivalents.

Our senior unsecured debt is currently rated investment grade by the three major
rating agencies. We aim to maintain an investment grade rating to enable us to
use debt comprised of unsecured, primarily fixed-rate debt (including the effect
of interest rate swaps) from public markets and banks. We also use secured
nonrecourse debt from institutional lenders and banks primarily for joint
venture financings. In addition, we periodically raise equity when we access the
public equity markets by issuing common and/or preferred shares.

We use our Revolving Credit Facility to initially finance much of our investing
activities.  We subsequently pay down the facility using cash available from
operations and proceeds from long-term borrowings, equity issuances and sales of
interests in properties. The lenders' aggregate commitment under the facility
is $800.0 million, with the ability for us to increase the lenders' aggregate
commitment to $1.25 billion, provided that there is no default under the
facility and subject to the approval of the lenders. The facility matures in
March 2023, and may be extended by two six-month periods at our option, provided
that there is no default under the facility and we pay an extension fee
of 0.075% of the total availability under the facility for each extension
period. As of June 30, 2021, the maximum borrowing capacity under this facility
totaled $800.0 million, of which $631.0 million was available.

We have a program in place under which we may offer and sell common shares in
at-the-market stock offerings having an aggregate gross sales price of up to
$300 million. Under this program, we may also, at our discretion, sell common
shares under forward equity sales agreements. The use of a forward equity sales
agreement would enable us to lock in a price on a sale of common shares when the
agreement is executed but defer receiving the proceeds from the sale until a
later date.

We believe that our liquidity and capital resources are adequate for our
near-term and longer-term requirements without necessitating property sales.
However, we may dispose of interests in properties opportunistically or when
market conditions otherwise warrant. In addition, we believe that we have the
ability to raise additional equity by selling interests in data center shells
through joint ventures.

(1)The contractual obligations set forth in this table exclude contracts for
property operations and certain other contracts entered into in the normal
course of business. Also excluded are accruals and payables incurred and
interest rate derivative liabilities, which are reflected in our reported
liabilities (although debt and lease liabilities are included on the table).
(2)Represents scheduled principal amortization payments and maturities only and
therefore excludes net debt discounts and deferred financing costs of $21.4
million. As of June 30, 2021, maturities in 2023 included $169.0 million that
may be extended to 2024, subject to certain conditions.
(3)We expect to pay these items using cash flow from operations.
(4)Represents interest costs for our outstanding debt as of June 30, 2021 for
the terms of such debt.  For variable rate debt, the amounts reflected above
used June 30, 2021 interest rates on variable rate debt in computing interest
costs for the terms of such debt. We expect to pay these items using cash flow
from operations.
(5)Represents contractual obligations pertaining to new development and
redevelopment activities.
(6)Due to the long-term nature of certain development and construction contracts
and leases included in these lines, the amounts reported in the table represent
our estimate of the timing for the related obligations being payable.
(7)Represents contractual obligations pertaining to projects for which we are
acting as construction manager on behalf of unrelated parties who are our
clients.  We expect to be reimbursed in full for these costs by our clients.

We expect to spend approximately $150 million on development costs and
approximately $55 million on improvements and leasing costs for operating
properties (including the commitments set forth in the table above) during the
remainder of 2021.  We expect to fund the development costs initially using
primarily borrowings under our Revolving Credit Facility.  We expect to fund
improvements to existing operating properties using cash flow from operating
activities.

Certain of our debt instruments require that we comply with a number of
restrictive financial covenants, including maximum leverage ratio, unencumbered
leverage ratio, minimum net worth, minimum fixed charge coverage, minimum
unencumbered interest coverage ratio, minimum debt service and maximum secured
indebtedness ratio.  As of June 30, 2021, we were compliant with these
covenants.

Off-Balance Sheet Arrangements

We had no material off-balance sheet arrangements during the six months ended June 30, 2021.



Inflation

Most of our tenants are obligated to pay their share of a property's operating
expenses to the extent such expenses exceed amounts established in their leases,
which are based on historical expense levels.  Some of our tenants are obligated
to pay their full share of a building's operating expenses.  These arrangements
somewhat reduce our exposure to increases in such costs resulting from
inflation.
