OFFICE PROPERTIES INCOME TRUST

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(dollars in thousands, except per share data)

(unaudited)

Note 1. Basis of Presentation

The accompanying condensed consolidated financial statements of Office Properties Income Trust and its subsidiaries, or OPI, we, us or our, are unaudited. Certain information and disclosures required by U.S. generally accepted accounting principles, or GAAP, for complete financial statements have been condensed or omitted. We believe the disclosures made are adequate to make the information presented not misleading. However, the accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2020, or our 2020 Annual Report. In the opinion of management, all adjustments, consisting of normal recurring accruals considered necessary for a fair statement of results for the interim period have been included. All intercompany transactions and balances with or among our consolidated subsidiaries have been eliminated. Our operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.

The preparation of these financial statements in conformity with GAAP requires us to make estimates and assumptions that affect reported amounts. Actual results could differ from those estimates. Significant estimates in the condensed consolidated financial statements include purchase price allocations, useful lives of fixed assets and assessment of impairment of real estate and the related intangibles.

Note 2. Per Common Share Amounts

We calculate basic earnings per common share by dividing net income (loss) by the weighted average number of our common shares outstanding during the period. We calculate diluted earnings per share using the more dilutive of the two class method or the treasury stock method. Unvested share awards and other potentially dilutive common shares, together with the related impact on earnings, are considered when calculating diluted earnings per share. For the three and six months ended June 30, 2021 and 2020, there were 0 dilutive common shares and certain unvested common shares were not included in the calculation of diluted earnings per share because to do so would have been antidilutive.

Note 3. Real Estate Properties

As of June 30, 2021, our wholly owned properties were comprised of 181 properties containing a combined approximately 24,091,000 rentable square feet. The aggregate undepreciated carrying value of our wholly owned properties as of June 30, 2021 was $3,889,200, including $41,236 classified as held for sale, and we had noncontrolling ownership interests of 51% and 50% in 2 unconsolidated joint ventures that own 3 properties containing a combined approximately 444,000 rentable square feet. We generally lease space at our properties on a gross lease, modified gross lease or net lease basis pursuant to fixed term contracts expiring between 2021 and 2053. Some of our leases generally require us to pay all or some property operating expenses and to provide all or most property management services. During the three months ended June 30, 2021, we entered into 25 leases for approximately 548,000 rentable square feet for a weighted (by rentable square feet) average lease term of 16.6 years and we made commitments for approximately $76,702 of leasing related costs. During the six months ended June 30, 2021, we entered into 45 leases for approximately 1,123,000 rentable square feet for a weighted (by rentable square feet) average lease term of 10.9 years and we made commitments for approximately $83,847 of leasing related costs. As of June 30, 2021, we had estimated unspent leasing related obligations of $113,099.

We regularly evaluate whether events or changes in circumstances have occurred that could indicate an impairment in the value of our long lived assets. If there is an indication that the carrying value of an asset is not recoverable, we estimate the projected undiscounted cash flows to determine if an impairment loss should be recognized. The future net undiscounted cash flows are subjective and are based in part on assumptions regarding hold periods, market rents and terminal capitalization rates. We determine the amount of any impairment loss by comparing the historical carrying value to estimated fair value. We estimate fair value through an evaluation of recent financial performance and projected discounted cash flows using standard industry valuation techniques. In addition to the consideration of impairment upon the events or changes in circumstances described above, we regularly evaluate the remaining lives of our long lived assets. If we change our estimate of the remaining lives, we allocate the carrying value of the affected assets over their revised remaining lives.

Acquisition Activities

During the six months ended June 30, 2021, we acquired 2 properties containing a combined approximately 877,000 rentable square feet for an aggregate purchase price of $548,933, including net purchase price adjustments of $1,761 and

OFFICE PROPERTIES INCOME TRUST

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(dollars in thousands, except per share data)

(unaudited)

acquisition related costs of $694. These acquisitions were accounted for as asset acquisitions. We allocated the purchase prices of these acquisitions based on the relative estimated fair values of the acquired assets and assumed liabilities as follows:

Acquisition Date	Location	Number of Properties	Rentable Square Feet	Purchase Price		Land		Buildings and Improvements		Acquired Real Estate Leases		Assumed Real Estate Lease Obligations
June 2021	Chicago, IL (1)	1	531,000	$	368,331	$	42,935	$	258,348	$	76,136	$	(9,088)
June 2021	Atlanta, GA	1	346,000	180,602		13,040		135,459		32,103		0
		2	877,000	$	548,933	$	55,975	$	393,807	$	108,239	$	(9,088)

(1)Purchase price includes an adjustment of $13,031 to record an estimated real estate tax liability as of the acquisition date.

As of July 28, 2021, we have entered into an agreement to acquire a property adjacent to a property we own in Boston, MA containing approximately 49,000 rentable square feet for $26,975, excluding acquisition related costs. This acquisition is expected to occur before the end of the third quarter. However, this acquisition is subject to conditions; accordingly, we cannot be sure that we will complete this acquisition or that this acquisition will not be delayed or the terms will not change.

Disposition Activities

During the six months ended June 30, 2021, we sold 2 properties and a warehouse facility adjacent to a property we own containing a combined approximately 1,692,000 rentable square feet for an aggregate sales price of $169,845, excluding closing costs. The sales of these properties, as presented in the table below, do not represent significant dispositions, individually or in the aggregate, nor do they represent a strategic shift in our business. As a result, the results of operations of these properties are included in continuing operations through the date of sale in our condensed consolidated statements of comprehensive income (loss).

Date of Sale	Number of Properties	Location	Rentable Square Feet	Gross  Sales Price (1)		Gain (Loss) on Sale of Real Estate		Loss on Impairment of Real Estate
January 2021	0	Kansas City, MO (2)	10,000	$	845	$	(63)	$	0

	2		1,692,000	$	169,845	$	54,118	$	5,371

(1)Gross sales price is the gross contract price, includes purchase price adjustments, if any, and excludes closing costs.

(2)Consists of a warehouse facility adjacent to a property we own in Kansas City, MO.

As of June 30, 2021, we had 3 properties under agreement to sell for an aggregate sales price of $21,920, excluding closing costs. These properties were classified as held for sale in our condensed consolidated balance sheet as of June 30, 2021 and are summarized below:

Date of Sale Agreement	Number of Properties	Location	Rentable Square Feet	Gross  Sales Price (1)		Loss on Impairment of Real Estate
April 2021	1	Liverpool, NY (2)	38,000	$	650	$	0

As of June 30, 2021, we also had an additional 4 properties with approximately 546,000 rentable square feet classified as held for sale in our condensed consolidated balance sheet. We recorded a $16,569 loss on impairment of real estate during the six months ended June 30, 2021, including $14,280 recorded during the three months ended June 30, 2021, to adjust the carrying value of these properties to their estimated fair values less cost to sell.

Unconsolidated Joint Ventures

We own interests in 2 joint ventures that own 3 properties. We account for these investments under the equity method of accounting. As of June 30, 2021 and December 31, 2020, our investments in unconsolidated joint ventures consisted of the following:

		OPI Carrying Value of Investments at

The following table provides a summary of the mortgage debt of our 2 unconsolidated joint ventures:

Joint Venture	Interest Rate (1)	Maturity Date	Principal Balance at June 30, 2021 and December 31, 2020 (2)
Prosperity Metro Plaza	4.09%	12/1/2029	$	50,000

Weighted Average / Total	3.93%		$	82,000

(1)Includes the effect of mark to market purchase accounting.

(2)Reflects the entire balance of the debt secured by the properties and is not adjusted to reflect the interests in the joint ventures we do not own. None of the debt is recourse to us.

At June 30, 2021, the aggregate unamortized basis difference of our 2 unconsolidated joint ventures of $7,220 is primarily attributable to the difference between the amount we paid to purchase our interest in these joint ventures, including transaction costs, and the historical carrying value of the net assets of these joint ventures. This difference is being amortized over the remaining useful life of the related properties and the resulting amortization expense is included in equity in net losses of investees in our condensed consolidated statements of comprehensive income (loss).

Note 4. Leases

Our leases provide for base rent payments and in addition may include variable payments. Rental income from operating leases, including any payments derived by index or market-based indices, is recognized on a straight line basis over the lease term when we have determined that the collectability of substantially all of the lease payments is probable. Some of our leases have options to extend or terminate the lease exercisable at the option of our tenants, which are considered when determining the lease term. In certain circumstances, some leases provide the tenant with the right to terminate if the legislature or other funding authority does not appropriate the funding necessary for the tenant to meet its lease obligations; we have determined the fixed non-cancelable lease term of these leases to be the full term of the lease because we believe the occurrence of early terminations to be a remote contingency based on both our historical experience and our assessments of the likelihood of lease cancellation on a separate lease basis.

We increased rental income to record revenue on a straight line basis by $3,847 and $3,468 for the three months ended June 30, 2021 and 2020, respectively, and $9,204 and $9,051 for the six months ended June 30, 2021 and 2020, respectively. Rents receivable, excluding properties classified as held for sale, include $74,674 and $68,824 of straight line rent receivables at June 30, 2021 and December 31, 2020, respectively.

We do not include in our measurement of our lease receivables certain variable payments, including payments determined by changes in the index or market-based indices after the inception of the lease, certain tenant reimbursements and other income until the specific events that trigger the variable payments have occurred. Such payments totaled $17,488 and $36,348 for the

three and six months ended June 30, 2021, respectively, of which tenant reimbursements totaled $16,639 and $34,442, respectively. For the three and six months ended June 30, 2020, such payments totaled $18,302 and $38,048, respectively, of which tenant reimbursements totaled $17,229 and $35,851, respectively.

Note 5. Concentration 

Tenant and Credit Concentration 

We define annualized rental income as the annualized contractual base rents from our tenants pursuant to our lease agreements as of the measurement date, plus straight line rent adjustments and estimated recurring expense reimbursements to be paid to us, and excluding lease value amortization. As of June 30, 2021, the U.S. government, 11 state governments and 4 other government tenants combined were responsible for approximately 31.9% of our annualized rental income. As of June 30, 2020, the U.S. government, 11 state governments and 2 other government tenants combined were responsible for approximately 35.1% of our annualized rental income. The U.S. government is our largest tenant by annualized rental income and represented approximately 22.0% and 25.2% of our annualized rental income as of June 30, 2021 and 2020, respectively. 

Geographic Concentration 

At June 30, 2021, our 181 wholly owned properties were located in 34 states and the District of Columbia. Properties located in California, Virginia, the District of Columbia, Illinois and Georgia were responsible for 12.1%, 12.1%, 9.4%, 9.0% and 7.9% of our annualized rental income as of June 30, 2021, respectively.

Note 6. Indebtedness

Our principal debt obligations at June 30, 2021 were: (1) $385,000 of outstanding borrowings under our $750,000 unsecured revolving credit facility; (2) $2,062,000 aggregate outstanding principal amount of senior unsecured notes; and (3) $98,903 aggregate outstanding principal amount of mortgage notes.

Our $750,000 revolving credit facility is governed by a credit agreement, or our credit agreement, with a syndicate of institutional lenders that includes a feature under which the maximum aggregate borrowing availability may be increased to up to $1,950,000 in certain circumstances. Our revolving credit facility is available for general business purposes, including acquisitions. The maturity date of our revolving credit facility is January 31, 2023 and, subject to our payment of an extension fee and meeting certain other conditions, we have the option to extend the stated maturity date of our revolving credit facility by 2 additional six month periods. We can borrow, repay and reborrow funds available under our revolving credit facility until maturity and no principal repayment is due until maturity. We are required to pay interest at a rate of LIBOR plus a premium, which was 110 basis points per annum at June 30, 2021, on the amount outstanding under our revolving credit facility, if any. We also pay a facility fee on the total amount of lending commitments under our revolving credit facility, which was 25 basis points per annum at June 30, 2021. Both the interest rate premium and facility fee are subject to adjustment based upon changes to our credit ratings. As of June 30, 2021 and December 31, 2020, the annual interest rate payable on borrowings under our revolving credit facility was 1.2%. The weighted average annual interest rate for borrowings under our revolving credit facility was 1.2% and 1.3% for the three months ended June 30, 2021 and 2020, respectively, and 1.2% and 2.1% for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021 and July 28, 2021, we had $385,000 and $380,000, respectively, outstanding under our revolving credit facility, and $365,000 and $370,000, respectively, available for borrowing.

Our credit agreement and senior unsecured notes indentures and their supplements provide for acceleration of payment of all amounts due thereunder upon the occurrence and continuation of certain events of default, such as, in the case of our credit agreement, a change of control of us, which includes The RMR Group LLC, or RMR LLC, ceasing to act as our business and property manager. Our credit agreement and senior unsecured notes indentures and their supplements also contain covenants, including covenants that restrict our ability to incur debts, require us to comply with certain financial covenants and, in the case of our credit agreement, restrict our ability to make distributions under certain circumstances. We believe we were in compliance with the terms and conditions of the respective covenants under our credit agreement and senior unsecured notes indentures and their supplements at June 30, 2021.

In May 2021, we issued $300,000 of 2.650% senior unsecured notes due 2026 in an underwritten public offering, raising net proceeds of $296,758, after deducting underwriters’ discounts and offering expenses. These notes require semi-annual payments of interest only through maturity on June 15, 2026 and may be repaid at par plus accrued and unpaid interest on or after May 15, 2026.

In June 2021, we redeemed, at par plus accrued interest, all $310,000 of our 5.875% senior unsecured notes due 2046. As a result of this redemption, we recognized a loss on early extinguishment of debt of $8,581 during the six months ended June 30, 2021, from the write off of unamortized debt issuance costs.

Also in June 2021, we prepaid, at a premium plus accrued interest, a mortgage note secured by 3 properties with an outstanding principal balance of $71,000, an annual interest rate of 3.55% and a maturity date in May 2023. As a result of the prepayment of this mortgage note, we recognized a loss on early extinguishment of debt of $3,213 during the six months ended June 30, 2021, from a prepayment penalty and the write off of unamortized discounts.

At June 30, 2021, 3 of our properties with an aggregate net book value of $190,969 were encumbered by mortgage notes with an aggregate principal amount of $98,903. Our mortgage notes are non-recourse, subject to certain limited exceptions and do not contain any material financial covenants.

We estimated the fair value of our senior unsecured notes (except for our senior unsecured notes due 2046 and 2050) using an average of the bid and ask price of the notes (Level 2 inputs as defined in the fair value hierarchy under GAAP) as of the measurement date. We estimated the fair value of our senior unsecured notes due 2046 and 2050 based on the closing price on The Nasdaq Stock Market LLC, or Nasdaq, (Level 1 inputs as defined in the fair value hierarchy under GAAP) as of the measurement date. We estimated the fair values of our mortgage notes payable using discounted cash flow analyses and currently prevailing market rates (Level 3 inputs as defined in the fair value hierarchy under GAAP) as of the measurement date. Because Level 3 inputs are unobservable, our estimated fair values may differ materially from the actual fair values.

Note 8. Shareholders’ Equity

Share Awards

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following information should be read in conjunction with our condensed consolidated financial statements and accompanying notes included in Part I, Item 1 of this Quarterly Report on Form 10-Q and with our 2020 Annual Report.

OVERVIEW (dollars in thousands, except per share and per square foot data)

We are a real estate investment trust, or REIT, organized under Maryland law. As of June 30, 2021, our wholly owned properties were comprised of 181 properties and we had noncontrolling ownership interests of 51% and 50% in two unconsolidated joint ventures that own three properties containing a combined approximately 444,000 rentable square feet. As of June 30, 2021, our properties are located in 34 states and the District of Columbia and contain approximately 24,091,000 rentable square feet. As of June 30, 2021, our properties were leased to 345 different tenants with a weighted average remaining lease term (based on annualized rental income) of approximately 5.9 years. The U.S. government is our largest tenant, representing approximately 22.0% of our annualized rental income as of June 30, 2021. The term annualized rental income as used herein is defined as the annualized contractual base rents from our tenants pursuant to our lease agreements as of June 30, 2021, plus straight line rent adjustments and estimated recurring expense reimbursements to be paid to us, and excluding lease value amortization.

COVID-19 Pandemic

The COVID-19 pandemic and the various governmental and market responses intended to contain and mitigate the spread of the virus and its detrimental public health impact have had a significant impact on the global economy, including the U.S. economy. Many of the restrictions that had been imposed in the United States during the pandemic have since been lifted and commercial activity in the United States has increasingly returned to pre-pandemic practices and operations. We are continuing to closely monitor the impact of the COVID-19 pandemic on all aspects of our business. To date, the COVID-19 pandemic has not had a significant impact on our business and we believe that our current financial resources, the characteristics of our portfolio, including the diversity of our tenant base, both geographically and by industry, and the financial strength and resources of our tenants, will enable us to withstand the COVID-19 pandemic. However, we have received requests from some of our tenants for rent assistance. As of July 27, 2021, we have granted temporary rent assistance totaling $2,483 to 18 tenants who represent approximately 3.1% of our annualized rental income as of June 30, 2021. This assistance generally entails a deferral of, in most cases, one month of rent pursuant to deferred payment plans which require the deferred rent amounts be payable over a 12-month period, all of which have commenced. As of July 27, 2021, we have collected $2,259, or 91.0%, of our granted rent deferrals.

There remains uncertainty as to the ultimate duration and severity of the COVID-19 pandemic, including risks that may arise from mutations or related strains of the virus, the ability to successfully administer vaccinations to a sufficient number of persons or attain immunity to the virus by natural or other means to achieve herd immunity, and the impact on the U.S. economy that may result from the inability of other countries to administer vaccinations to their citizens or their citizens’ ability to otherwise achieve immunity to the virus. As a result, we are unable to determine what the ultimate impact will be on our, our tenants’ and other stakeholders’ businesses, operations, financial results and financial position. For more information and risks relating to the COVID-19 pandemic on us and our business, see Part I, Item 1, “Business—COVID-19 Pandemic” and Part I, Item 1A, “Risk Factors”, of our 2020 Annual Report.

During the three and six months ended June 30, 2021 and 2020, amounts capitalized at our properties for lease related costs, building improvements and development, redevelopment and other activities were as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020
Lease related costs (1)	$	11,215	$	11,921	$	18,185	$	19,034
Building improvements (2)	7,765		10,005		12,291		19,235
Recurring capital expenditures	18,980		21,926		30,476		38,269
Development, redevelopment and other activities (3)	12,738		2,578		17,644		5,739
Total capital expenditures	$	31,718	$	24,504	$	48,120	$	44,008

(1)Lease related costs generally include capital expenditures used to improve tenants’ space or amounts paid directly to tenants to improve their space and leasing related costs, such as brokerage commissions and other tenant inducements.

(2)Building improvements generally include expenditures to replace obsolete building components and expenditures that extend the useful life of existing assets.

(3)Development, redevelopment and other activities generally include capital expenditure projects that reposition a property or result in new sources of revenue.

As of June 30, 2021, we have estimated unspent leasing related obligations of $113,099, of which we expect to spend $67,272 over the next 12 months.

As of June 30, 2021, we had leases at our properties totaling approximately 1,897,000 rentable square feet that were scheduled to expire through June 30, 2022. As of July 28, 2021, we expect tenants with leases totaling approximately 923,000 rentable square feet that are scheduled to expire through June 30, 2022, to not renew their leases upon expiration and we cannot be sure as to whether other tenants will renew their leases upon expiration. Of the approximately 923,000 rentable square feet that are expiring and expected to not renew, properties containing approximately 532,000 rentable square feet have been sold, resulting in a net approximately 391,000 rentable square feet, or approximately 1.6% of our total rentable square feet as of June 30, 2021, that are expiring through June 30, 2022 which we expect to not renew. As a result of the COVID-19 pandemic and its economic impact, overall leasing activity has been volatile during 2021 and may remain so until office property market conditions meaningfully improve and stabilize for a sustained period. However, we remain focused on proactive dialogues with our existing tenants and overall tenant retention. Prevailing market conditions and government and other tenants’ needs at the time we negotiate and enter leases or lease renewals will generally determine rental rates and demand for leased space at our properties, and market conditions and our tenants’ needs are beyond our control. Whenever we renew or enter into new leases for our properties, we intend to seek rents which are equal to or higher than our historical rents for the same properties; however, our ability to maintain or increase the rents for our current properties will depend in large part upon market conditions, which are beyond our control. We cannot be sure of the rental rates which will result from our ongoing negotiations regarding lease renewals or any new or renewed leases we may enter; also, we may experience material declines in our rental income due to vacancies upon lease expirations or early terminations. Additionally, we may incur significant costs to renew our leases with current tenants or lease our properties to new tenants.

As of June 30, 2021, our lease expirations by year are as follows (square feet in thousands):

Year (1)	Number of Leases Expiring	Leased Square Feet Expiring (2)	Percent of Total		Cumulative Percent of Total		Annualized Rental Income Expiring		Percent of Total		Cumulative Percent of Total

(1)The year of lease expiration is pursuant to current contract terms. Some of our leases allow the tenants to vacate the leased premises before the stated expirations of their leases with little or no liability. As of June 30, 2021, tenants occupying approximately 7.2% of our rentable square feet and responsible for approximately 7.9% of our annualized rental income as of June 30, 2021 currently have exercisable rights to terminate their leases before the stated terms of their leases expire. Also, in 2021, 2022, 2023, 2024, 2025, 2026, 2027, 2028, 2029, and 2035, early termination rights become exercisable by other tenants who currently occupy an additional approximately 0.4%, 2.9%, 2.5%, 1.2%, 2.1%, 1.2%, 0.7%, 2.7%, 0.1%, and 0.3% of our rentable square feet, respectively, and contribute an additional approximately 0.4%, 3.0%, 3.5%, 1.7%, 3.3%, 1.4%, 1.1%, 4.9%, 0.2%, and 0.4% of our annualized rental income, respectively, as of June 30, 2021. In addition, as of June 30, 2021, pursuant to leases with 13 of our tenants, these tenants have rights to terminate their leases if their respective legislature or other funding authority does not appropriate rent amounts in their respective annual budgets. These 13 tenants occupy approximately 5.2% of our rentable square feet and contribute approximately 5.7% of our annualized rental income as of June 30, 2021.

(2)Leased square feet is pursuant to leases existing as of June 30, 2021, and includes (i) space being fitted out for tenant occupancy pursuant to our lease agreements, if any, and (ii) space which is leased, but is not occupied or is being offered for sublease by tenants, if any. Square feet measurements are subject to changes when space is remeasured or reconfigured for new tenants.

We generally will seek to renew or extend the terms of leases in our single tenant properties when they expire. Because of the capital many of the tenants in these properties have invested in the properties and because many of these properties appear to be of strategic importance to the tenants’ businesses, we believe that it is likely that these tenants will renew or extend their leases prior to when they expire. If we are unable to extend or renew our leases, it may be time consuming and expensive to relet some of these properties.

We believe that recent government budgetary and spending priorities and enhancements in technology have resulted in a decrease in government office use for employees. Furthermore, over the past several years, government tenants have reduced their space utilization per employee and consolidated government tenants into existing government owned properties. This activity has reduced the demand for government leased space. Our historical experience with respect to properties of the type we own that are majority leased to government tenants has been that government tenants frequently renew leases to avoid the costs and disruptions that may result from relocating their operations. However, efforts to manage space utilization rates may result in our tenants exercising early termination rights under our leases, vacating our properties upon expiration of our leases in order to relocate, or renewing their leases for less space than they currently occupy. Also, our government tenants’ desire to reconfigure leased office space to manage utilization per employee may require us to spend significant amounts for tenant improvements, and tenant relocations are often more prevalent in those circumstances. Increasing uncertainty with respect to government agency budgets and funding to implement relocations, consolidations and reconfigurations has resulted in delayed decisions by some of our government tenants and their reliance on short term lease renewals; however, activity prior to the outbreak of the COVID-19 pandemic suggested that the U.S. government had begun to shift its leasing strategy to include longer term leases and was actively exploring 10 to 20 year lease terms at renewal, in some instances. It is also possible that as a result of the COVID-19 pandemic, government tenants may seek to manage space utilization rates in order to provide greater physical distancing for employees, mostly through lease renewals, which may require us to spend significant amounts for tenant improvements. However, the COVID-19 pandemic and its aftermath have had negative impacts on government budgets and resources, although there are indications that to date, certain of those impacts may not have been as negative as originally expected, and it is unclear what the effect of these impacts will be on government demand for leasing office space. In addition, the new presidential administration may result in a change in the federal government’s policy priorities, which may impact

20

leasing at our government leased properties. Given the significant uncertainties, including as to the COVID-19 pandemic, its economic impact and its aftermath and the new presidential administration, we are unable to reasonably project what the financial impact of market conditions or changing government circumstances will be on our financial results for future periods.

As of June 30, 2021, we derive 21.8% of our annualized rental income from our properties located in the metropolitan Washington, D.C. market area, which includes Washington, D.C., Northern Virginia and suburban Maryland. A downturn in economic conditions in this area, including as a result of the COVID-19 pandemic, could result in reduced demand from tenants for our properties or reduce the rents that our tenants in this area are willing to pay when our leases expire or terminate and when renewal or new terms are negotiated. Additionally, in recent years there has been a decrease in demand for new leased office space by the U.S. government in the metropolitan Washington, D.C. market area, and that could increase competition for government tenants and adversely affect our ability to retain government tenants when our leases expire.

Our manager, RMR LLC, employs a tenant review process for us. RMR LLC assesses tenants on an individual basis based on various applicable credit criteria. In general, depending on facts and circumstances, RMR LLC evaluates the creditworthiness of a tenant based on information concerning the tenant that is provided by the tenant and, in some cases, information that is publicly available or obtained from third party sources. RMR LLC also often uses a third party service to monitor the credit ratings, both actual and implied, of our existing tenants. We consider investment grade tenants to include: (a) investment grade rated tenants; (b) tenants with investment grade rated parent entities that guarantee the tenant’s lease obligations; and/or (c) tenants with investment grade rated parent entities that do not guarantee the tenant’s lease obligations. As of June 30, 2021, tenants contributing 54.1% of annualized rental income were investment grade rated (or their payment obligations were guaranteed by an investment grade rated parent) and tenants contributing an additional 9.2% of annualized rental income were subsidiaries of an investment grade rated parent (although these parent entities were not liable for the payment of rents).

(1)Comparable properties consists of 169 properties we owned on June 30, 2021 and which we owned continuously since April 1, 2020 and excludes properties classified as held for sale and properties undergoing significant redevelopment, if any, and three properties owned by two unconsolidated joint ventures in which we own 51% and 50% interests.

(2)Our definition of net operating income, or NOI, and our reconciliation of net income (loss) to NOI are included below under the heading “Non-GAAP Financial Measures.”

References to changes in the income and expense categories below relate to the comparison of consolidated results for the three months ended June 30, 2021, compared to the three months ended June 30, 2020.

Rental income. The decrease in rental income reflects decreases in rental income of $4,681 as a result of property disposition activities, $4,180 for properties undergoing significant redevelopment and $1,121 related to comparable properties, offset by an increase in rental income of $1,478 related to acquired properties. The decrease in rental income for properties undergoing significant redevelopment is primarily due to the reduction in occupied space at a property located in Washington, D.C. that began a redevelopment project during the 2021 period. The decrease in rental income for comparable properties is primarily due to reductions in occupied space at certain of our properties in the 2021 period. Rental income includes non-cash straight line rent adjustments totaling $3,847 in the 2021 period and $3,468 in the 2020 period, and amortization of acquired real estate leases and assumed real estate lease obligations totaling ($667) in the 2021 period and ($1,405) in the 2020 period.

24

Real estate taxes. The increase in real estate taxes primarily reflects increases in real estate taxes of $436 for comparable properties, $139 related to acquired properties and $29 related to property disposition activities, offset by a decrease of $473 for properties undergoing significant redevelopment. Real estate taxes for comparable properties increased primarily due to refunds received in the 2020 period at certain of our properties as a result of successful real estate tax appeals, as well as the effect of a higher valuation assessment at certain of our properties in the 2021 period.

Utility expenses. The increase in utility expenses reflects increases in utility expenses of $308 for comparable properties and $11 for acquired properties, offset by a decrease in utility expenses of $163 for properties undergoing significant redevelopment and $47 related to property disposition activities. The increase in utility expenses for comparable properties is primarily related to utility expenses previously being paid by one of our tenants that are now being paid by us pursuant to a lease amendment with that tenant effective in January 2021.

Other operating expenses. Other operating expenses consist of salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense, other direct costs of operating our properties and property management fees. The decrease in other operating expenses primarily reflects a decrease of $541 related to property disposition activities, $377 for properties undergoing significant redevelopment and $79 for comparable properties, offset by an increase in other operating expenses of $108 for acquired properties.

Depreciation and amortization. The decrease in depreciation and amortization primarily reflects decreases of $7,006 for comparable properties and $2,597 related to property disposition activities, offset by an increase of $804 for acquired properties. Depreciation and amortization for comparable properties declined due to certain leasing related assets becoming fully depreciated after April 1, 2020.

Loss on impairment of real estate. We recorded a $48,197 loss on impairment of real estate in the 2021 period to reduce the carrying value of five properties to their estimated fair values less costs to sell, which includes $33,917 related to a property in Fresno, CA containing approximately 532,000 square feet that was sold in July 2021 and $14,280 related to four properties containing approximately 546,000 rentable square feet that were classified as held for sale as of June 30, 2021.

General and administrative. General and administrative expenses consist of fees pursuant to our business management agreement, equity compensation expense, legal and accounting fees, Trustees’ fees and expenses, securities listing and transfer agency fees and other costs relating to our status as a publicly traded company. The increase in general and administrative expenses is primarily the result of $5,911 of estimated business management incentive fees recorded in the 2021 period and an increase in base business management fees resulting from an increase in average total market capitalization in the 2021 period compared to the 2020 period, partially offset by the expiration of an office lease in January 2021 for which we were the lessee.

Gain on sale of real estate. Gain on sale of real estate reflects activity related to property sales during the 2021 and 2020 periods.

Interest and other income. The decrease in interest and other income is primarily due to the June 2020 payoff of a mortgage note receivable in connection with a property we sold in 2016 and lower returns on cash invested in the 2021 period compared to the 2020 period.

Interest expense. The increase in interest expense is primarily due to the issuance of $162,000 of 6.375% senior unsecured notes in June and July 2020, the issuance of $250,000 of our 4.50% senior unsecured notes in September 2020 and the issuance of $300,000 of 2.650% senior unsecured notes in May 2021, partially offset by the redemption of all $310,000 of our 5.875% senior unsecured notes in June 2021, lower interest expense incurred as a result of having a lower average balance outstanding under our revolving credit facility during the 2021 period compared to the 2020 period and the repayment of one mortgage note with a principal balance of $39,635 in August 2020.

Loss on early extinguishment of debt. We recorded a loss on early extinguishment of debt of $11,794 in the 2021 period from prepayment fees incurred and the write off of unamortized discounts and debt issuance costs associated with the prepayment of one mortgage note and the redemption of our senior unsecured notes due 2046. In the 2020 period, we recorded a loss on early extinguishment of debt of $557 resulting from a loss on the settlement of a mortgage note receivable related to a property sold in 2016, partially offset by the write off of unamortized premiums associated with the prepayment of a mortgage note.

Income tax (expense) benefit. Income tax (expense) benefit is primarily the result of operating income or losses in jurisdictions where we are subject to state income taxes.

25

Equity in net losses of investees. Equity in net losses of investees represents our proportionate share of losses from our investments in two unconsolidated joint ventures.

Net income (loss). Net income (loss) and net income (loss) per basic and diluted common share decreased in the 2021 period compared to the 2020 period primarily as a result of the changes noted above.

(1)Comparable properties consists of 168 properties we owned on June 30, 2021 and which we owned continuously since January 1, 2020 and excludes properties classified as held for sale and properties undergoing significant redevelopment, if any, and three properties owned by two unconsolidated joint ventures in which we own 51% and 50% interests.

(2)Our definition of NOI and our reconciliation of net income (loss) to NOI are included below under the heading “Non-GAAP Financial Measures.”

References to changes in the income and expense categories below relate to the comparison of consolidated results for the six months ended June 30, 2021, compared to the six months ended June 30, 2020.

Rental income. The decrease in rental income reflects decreases in rental income of $10,920 related to property disposition activities, $4,242 for properties undergoing significant redevelopment and $1,068 for comparable properties, offset by an increase in rental income of $2,365 for acquired properties. The decrease in rental income for properties undergoing significant redevelopment is primarily due to the reduction in occupied space at a property located in Washington, D.C. that began a redevelopment project during the 2021 period. The decrease in rental income for comparable properties is primarily due to

26

decreased parking revenue at certain of our properties in the 2021 period due to lower parking activity resulting from the COVID-19 pandemic and reductions in occupied space at certain of our properties in the 2021 period. Rental income includes non-cash straight line rent adjustments totaling $9,204 in the 2021 period and $9,051 in the 2020 period, and amortization of acquired leases and assumed lease obligations totaling $(1,389) in the 2021 period and $(2,837) in the 2020 period.

Real estate taxes. The decrease in real estate taxes primarily reflects decreases in real estate taxes of $664 related to property disposition activities and $635 for properties undergoing significant redevelopment, offset by increases in real estate taxes of $630 for comparable properties and $147 for acquired properties. Real estate taxes for comparable properties increased primarily due to refunds received in the 2020 period at certain of our properties as a result of successful real estate tax appeals, as well as the effect of higher real estate tax rates and valuation assessments at certain of our properties in the 2021 period.

Utility expenses. The decrease in utility expenses reflects decreases in utility expenses of $264 related to property disposition activities, $134 for properties undergoing significant redevelopment and $88 for comparable properties, offset by an increase in utility expenses of $15 for acquired properties. Utility expenses for comparable properties declined primarily due to a decrease in electricity and water usage resulting from cost savings initiatives implemented by our manager, RMR LLC, in response to decreased space utilization at our properties as a result of the COVID-19 pandemic, partially offset by an increase related to utility expenses in the 2021 period previously paid directly by one of our tenants that are now being paid by us pursuant to a lease amendment with that tenant effective in January 2021.

Other operating expenses. The decrease in other operating expenses primarily reflects decreases in other operating expenses of $1,517 related to property disposition activities and $449 for properties undergoing significant redevelopment, offset by increases in other operating expenses of $453 for comparable properties and $183 for acquired properties. Other operating expenses for comparable properties increased primarily due to higher snow removal and insurance costs in the 2021 period, partially offset by lower parking garage costs due to lower parking activity at certain of our properties resulting from the COVID-19 pandemic and lower cleaning costs resulting from cost savings initiatives implemented by our manager, RMR LLC, in response to decreased space utilization at our properties as a result of the COVID-19 pandemic.

Depreciation and amortization. The decrease in depreciation and amortization primarily reflects decreases of $6,528 for comparable properties and $2,331 related to property disposition activities, offset by increases of $1,158 for acquired properties and $46 for properties undergoing significant redevelopment. Depreciation and amortization for comparable properties decreased due to certain leasing related assets becoming fully depreciated after January 1, 2020.

Loss on impairment of real estate. We recorded a $55,857 loss on impairment of real estate in the 2021 period to reduce the carrying value of six properties to their estimated fair values less costs to sell, which includes $5,371 related to a property in Huntsville, AL containing approximately 1,371,000 rentable square feet that was sold in April 2021, $33,917 related to a property in Fresno, CA containing approximately 532,000 rentable square feet that was sold in July 2021 and $16,569 related to four properties containing approximately 546,000 rentable square feet that were classified as held for sale as of June 30, 2021.

General and administrative. The increase in general and administrative expenses is primarily the result of $11,111 of estimated business management incentive fees recorded in the 2021 period, partially offset by the expiration of an office lease in January 2021 for which we were the lessee, lower accounting and legal costs and a decrease in base business management fees resulting from decreases in our share price in the 2021 period compared to the 2020 period.

Gain on sale of real estate. We recorded a $54,118 net gain on sale of real estate resulting from the sale of two properties during the 2021 period. We recorded a $10,822 net gain on sale of real estate resulting from the sale of six properties during the 2020 period.

Interest and other income. The decrease in interest and other income is primarily due to a settlement payment we received in the 2020 period resulting from a dispute with a vendor, the June 2020 payoff of a mortgage note receivable in connection with a property we sold in 2016 and the effect of lower returns on cash invested in the 2021 period compared to the 2020 period.

Interest expense. The increase in interest expense is primarily due to the issuance of $162,000 of 6.375% senior unsecured notes in June and July 2020, the issuance of $250,000 of our 4.50% senior unsecured notes in September 2020 and the issuance of $300,000 of 2.650% senior unsecured notes in May 2021, partially offset by the redemption of all $310,000 of our 5.875% senior unsecured notes in June 2021, lower interest expense incurred as a result of having a lower average balance outstanding under our revolving credit facility during the 2021 period compared to the 2020 period, lower average interest rates on amounts outstanding and the repayment of four mortgage notes with an aggregate principal balance of $152,187 in 2020.

27

Loss on early extinguishment of debt. We recorded a loss on early extinguishment of debt of $11,794 in the 2021 period from prepayment fees incurred and the write off of unamortized discounts and debt issuance costs associated with the prepayment of one mortgage note and the redemption of our senior unsecured notes due 2046. In the 2020 period, we recorded a loss on early extinguishment of debt of $3,839 from prepayment fees incurred, the write off of unamortized discounts, premiums and debt issuance costs associated with the prepayment of three mortgage notes and a loss on the settlement of a mortgage note receivable related to a property sold in 2016.

Income tax expense. Income tax expense primarily reflects operating income earned in jurisdictions where we are subject to state income taxes.

Equity in net losses of investees. Equity in net losses of investees represents our proportionate share of losses from our investments in two unconsolidated joint ventures.

Net income (loss). Our net income (loss) and net income (loss) per basic and diluted common share decreased in the 2021 period compared to the 2020 period primarily as a result of the changes noted above.

Non-GAAP Financial Measures

We present certain “non-GAAP financial measures” within the meaning of the applicable rules of the Securities and Exchange Commission, or SEC, including the calculations below of NOI, funds from operations, or FFO, and normalized funds from operations, or Normalized FFO. These measures do not represent cash generated by operating activities in accordance with GAAP and should not be considered alternatives to net income (loss) as indicators of our operating performance or as measures of our liquidity. These measures should be considered in conjunction with net income (loss) as presented in our condensed consolidated statements of comprehensive income (loss). We consider these non-GAAP measures to be appropriate supplemental measures of operating performance for a REIT, along with net income (loss). We believe these measures provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation and amortization expense, they may facilitate a comparison of our operating performance between periods and with other REITs and, in the case of NOI, reflecting only those income and expense items that are generated and incurred at the property level may help both investors and management to understand the operations of our properties.

Net Operating Income

The calculation of NOI excludes certain components of net income (loss) in order to provide results that are more closely related to our property level results of operations. We calculate NOI as shown below. We define NOI as income from our rental of real estate less our property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions that we record as depreciation and amortization expense. We use NOI to evaluate individual and company-wide property level performance. Other real estate companies and REITs may calculate NOI differently than we do.

The following table presents the reconciliation of net income (loss) to NOI for the three and six months ended June 30, 2021 and 2020.

	Three Months Ended June 30,				Six Months Ended June 30,
	2021		2020		2021		2020

Funds From Operations and Normalized Funds From Operations

We calculate FFO and Normalized FFO as shown below. FFO is calculated on the basis defined by The National Association of Real Estate Investment Trusts, which is net income (loss), calculated in accordance with GAAP, plus real estate depreciation and amortization of consolidated properties and our proportionate share of the real estate depreciation and amortization of unconsolidated joint venture properties, but excluding impairment charges on real estate assets and any gain or loss on sale of real estate, as well as certain other adjustments currently not applicable to us. In calculating Normalized FFO, we adjust for the other items shown below and include business management incentive fees, if any, only in the fourth quarter versus the quarter when they are recognized as an expense in accordance with GAAP due to their quarterly volatility not necessarily being indicative of our core operating performance and the uncertainty as to whether any such business management incentive fees will be payable when all contingencies for determining such fees are known at the end of the calendar year. FFO and Normalized FFO are among the factors considered by our Board of Trustees when determining the amount of distributions to our shareholders. Other factors include, but are not limited to, requirements to maintain our qualification for taxation as a REIT, limitations in our credit agreement and public debt covenants, the availability to us of debt and equity capital, our expectation of our future capital requirements and operating performance and our expected needs for and availability of cash to pay our obligations. Other real estate companies and REITs may calculate FFO and Normalized FFO differently than we do.

The following table presents the reconciliation of net income (loss) to FFO and Normalized FFO for the three and six months ended June 30, 2021 and 2020.

	Three Months Ended June 30,				Six Months Ended June 30,

LIQUIDITY AND CAPITAL RESOURCES

Our Operating Liquidity and Resources (dollar amounts in thousands, except per share amounts)

Our principal sources of funds to meet operating and capital expenses, pay debt service obligations and make distributions to our shareholders are the operating cash flows we generate from our properties, net proceeds from property sales and borrowings under our revolving credit facility. We believe that these sources of funds will be sufficient to meet our operating and capital expenses, pay debt service obligations and make distributions to our shareholders for the next 12 months and for the foreseeable future thereafter. Our future cash flows from operating activities will depend primarily upon:

•our ability to collect rent from our tenants;

•our ability to maintain or increase the occupancy of, and the rental rates at, our properties;

•our ability to control operating and capital expenses at our properties;

•our ability to successfully sell properties that we market for sale;

•our ability to develop or redevelop properties to produce cash flows in excess of our cost of capital; and

29

•our ability to purchase additional properties which produce cash flows from operations in excess of our cost of acquisition capital and property operating and capital expenses.

On July 15, 2021, we announced a regular quarterly cash distribution of $0.55 per common share ($2.20 per common share per year). We determine our distribution payout ratio with consideration for our expected capital expenditures as well as cash flows from operations and debt obligations.

We expect to accretively grow our property portfolio through our capital recycling program, pursuant to which we plan to sell certain properties from time to time to fund future acquisitions and to maintain leverage consistent with our current investment grade ratings with a goal of (1) improving the asset quality of our portfolio by reducing the average age of our properties, lengthening the weighted average term of our leases and increasing the likelihood of retaining our tenants and (2) increasing our cash available for distribution. During the six months ended June 30, 2021, we acquired two properties for an aggregate purchase price of $550,000, excluding purchase price adjustments and acquisition related costs, and we sold two properties and a warehouse facility adjacent to a property we own for an aggregate sales price of $169,845, excluding closing costs. Since July 1, 2021, we have sold two properties for an aggregate sales price of $6,650, excluding closing costs. In addition, we have entered into an agreement to sell one property for a sales price of $15,270, excluding closing costs, and entered into an agreement to acquire a property adjacent to a property we own in Boston, MA for $26,975, excluding acquisition related costs. Given the current economic conditions, we continue to carefully consider our capital allocation strategy and believe we are well positioned to opportunistically recycle and deploy capital.

Our future purchases of properties cannot be accurately projected because such purchases depend upon purchase opportunities which come to our attention and our ability to successfully complete the acquisitions. We generally do not intend to purchase “turn around” properties, or properties which do not generate positive cash flows.

The following is a summary of our sources and uses of cash flows for the periods presented, as reflected in our condensed consolidated statements of cash flows:

	Six Months Ended June 30,
	2021		2020
Cash, cash equivalents and restricted cash at beginning of period	$	56,855	$	100,696
Net cash provided by (used in):
Operating activities	117,376		111,190
Investing activities	(400,467)		40,934
Financing activities	246,317		(222,719)
Cash, cash equivalents and restricted cash at end of period	$	20,081	$	30,101

The increase in cash provided by operating activities for the 2021 period compared to the 2020 period was a result of favorable changes in working capital in the 2021 period compared to the 2020 period, partially offset by a decline in NOI as a result of property sales. The increase in cash used in investing activities in the 2021 period compared to the 2020 period is primarily due to higher acquisition activity in the 2021 period compared to the 2020 period, partially offset by higher cash proceeds from our sales of properties. The increase in cash provided by financing activities in the 2021 period compared to the 2020 period is primarily due to the issuance of $300,000 of 2.650% senior unsecured notes due 2026 and net borrowing activity under our revolving credit facility to fund acquisition activity in the 2021 period, partially offset by the redemption of our 5.875% senior unsecured notes due 2046, compared to net debt repayment activity in the 2020 period that included the redemption of all $400,000 of our 3.60% senior unsecured notes due 2020 and the repayment of mortgage notes totaling approximately $113,000, which was partially offset by the issuance of $162,000 of 6.375% senior unsecured notes due 2050 and borrowings under our revolving credit facility to facilitate certain of these repayments.

Our Investment and Financing Liquidity and Resources (dollar amounts in thousands, except per share amounts)

In order to fund acquisitions and to meet cash needs that may result from our desire or need to make distributions or pay operating or capital expenses, we maintain a $750,000 revolving credit facility. The maturity date of our revolving credit facility is January 31, 2023 and, subject to our payment of an extension fee and meeting certain other conditions, we have the option to extend the stated maturity date of our revolving credit facility by two additional six month periods. We can borrow, repay and reborrow funds available under our revolving credit facility until maturity, and no principal repayment is due until maturity. We are required to pay interest at a rate of LIBOR plus a premium, which was 110 basis points per annum at June 30, 2021, on the amount outstanding under our revolving credit facility, if any. We also pay a facility fee on the total amount of

30

lending commitments under our revolving credit facility, which was 25 basis points per annum at June 30, 2021. Both the interest rate premium and facility fee are subject to adjustment based upon changes to our credit ratings. As of June 30, 2021, the annual interest rate payable on borrowings under our revolving credit facility was 1.2%. As of June 30, 2021 and July 28, 2021, we had $385,000 and $380,000, respectively, outstanding under our revolving credit facility, and $365,000 and $370,000, respectively, available for borrowing.

Our credit agreement includes a feature under which the maximum borrowing availability may be increased to up to $1,950,000 in certain circumstances.

Our credit agreement provides that, with certain exceptions, a subsidiary of ours is required to guaranty our obligations under our $750,000 revolving credit facility only if that subsidiary has separately incurred debt (other than nonrecourse debt), within the meaning specified in our credit agreement, or provided a guarantee of debt incurred by us or any of our other subsidiaries.

In May 2021, we issued $300,000 of 2.650% senior unsecured notes due 2026 in an underwritten public offering, raising net proceeds of $296,758, after deducting underwriters’ discounts and offering expenses. These notes require semi-annual payments of interest only through maturity on June 15, 2026 and may be repaid at par plus accrued and unpaid interest on or after May 15, 2026.

In June 2021, we redeemed, at par plus accrued interest, all $310,000 of our 5.875% senior unsecured notes due 2046 using cash on hand and the net proceeds from the issuance of our 2.650% senior unsecured notes due 2026.

Also in June 2021, we prepaid, at a premium plus accrued interest, a mortgage note secured by three properties with an outstanding principal balance of $71,000, an annual interest rate of 3.55% and a maturity date in May 2023 using cash on hand and borrowings under our revolving credit facility.

As of June 30, 2021, our debt maturities (other than our revolving credit facility), consisting of senior unsecured notes and mortgage notes, are as follows:

Year	Debt Maturities
2021	$	601
2022	625,518
2023	72,784
2024	350,000
2025	650,000
Thereafter	462,000
Total	$	2,160,903

None of our unsecured debt obligations require sinking fund payments prior to their maturity dates. Our $98,903 in mortgage debts generally require monthly payments of principal and interest through maturity.

In addition to our debt obligations, as of June 30, 2021, we have estimated unspent leasing related obligations of $113,099, of which we expect to spend $67,272 over the next 12 months.

We are currently in the process of redeveloping a property located in Washington, D.C. We currently estimate the total project costs associated with this redevelopment will be approximately $200,000 and completion of the redevelopment in the first quarter of 2023. As of June 30, 2021, we have incurred approximately $14,700 related to this project. In June 2021, we entered into a 30-year lease for approximately 230,000 rentable square feet at this property that is approximately 25.1% higher than the prior rental rate for the same space, making the redevelopment project 54% pre-leased.

We currently expect to use cash balances, borrowings under our revolving credit facility, net proceeds from property sales, incurrences or assumptions of mortgage debt and net proceeds from offerings of debt or equity securities to fund our future operations, capital expenditures, distributions to our shareholders and property acquisitions. When significant amounts are outstanding under our revolving credit facility or the maturities of our indebtedness approach, we expect to explore refinancing alternatives. Such alternatives may include incurring term debt, issuing debt or equity securities, extending the maturity date of our revolving credit facility and entering into a new revolving credit facility. We may assume additional mortgage debt in connection with our acquisitions or elect to place new mortgages on properties we own as a source of financing. We may also seek to participate in additional joint venture or other arrangements that may provide us with additional sources of financing.

31

Although we cannot be sure that we will be successful in consummating any particular type of financing, we believe that we will have access to financing, such as debt and equity offerings, to fund future acquisitions and capital expenditures and to pay our obligations. We currently have an effective shelf registration statement that allows us to issue public securities on an expedited basis, but it does not assure that there will be buyers for such securities.

Our ability to obtain, and the costs of, our future debt financings will depend primarily on credit market conditions and our creditworthiness. We have no control over market conditions. Potential investors and lenders likely will evaluate our ability to pay distributions to shareholders, fund required debt service and repay debts when they become due by reviewing our business practices and plans to balance our use of debt and equity capital so that our financial profile and leverage ratios afford us flexibility to withstand any reasonably anticipated adverse changes. Similarly, our ability to raise equity capital in the future will depend primarily upon equity capital market conditions and our ability to conduct our business to maintain and grow our operating cash flows. We intend to conduct our business in a manner that will afford us reasonable access to capital for investment and financing activities, but we cannot be sure that we will be able to successfully carry out this intention. For instance, it is uncertain what the duration and severity of the COVID-19 pandemic and its ultimate economic impact will be. A protracted and extensive economic downturn may cause a decline in financing availability and increased costs for financings. Further, such conditions could also disrupt capital markets and limit our access to financing from public sources.

During the six months ended June 30, 2021, we paid quarterly distributions to our shareholders totaling $53,150 using cash on hand. On July 15, 2021, we declared a regular quarterly distribution payable to shareholders of record on July 26, 2021 of $0.55 per share, or approximately $26,600. We expect to pay this distribution on or about August 19, 2021 using cash on hand and borrowings under our revolving credit facility. For more information regarding the distributions we paid and declared during 2021, see Note 8 to the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

We own 51% and 50% interests in two unconsolidated joint ventures which own three properties. The properties owned by these joint ventures are encumbered by an aggregate $82,000 principal amount of mortgage indebtedness, none of which is recourse to us. We do not control the activities that are most significant to these joint ventures and, as a result, we account for our investments in these joint ventures under the equity method of accounting. For more information on the financial condition and results of operations of these joint ventures, see Note 3 to the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. Other than these joint ventures, as of June 30, 2021, we had no off balance sheet arrangements that have had or that we expect would be reasonably likely to have a material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Debt Covenants (dollars in thousands)

Our principal debt obligations at June 30, 2021 consisted of $385,000 of outstanding borrowings under our $750,000 unsecured revolving credit facility, an aggregate outstanding principal balance of $2,062,000 of public issuances of senior unsecured notes and mortgage notes with an aggregate outstanding principal balance of $98,903, that were assumed in connection with certain of our acquisitions. Also, the three properties owned by two joint ventures in which we own 51% and 50% interests secure two additional mortgage notes. Our publicly issued senior unsecured notes are governed by indentures and their supplements. Our credit agreement and our senior unsecured notes indentures and their supplements provide for acceleration of payment of all amounts outstanding upon the occurrence and continuation of certain events of default, such as, in the case of our credit agreement, a change of control of us, which includes RMR LLC ceasing to act as our business and property manager. Our credit agreement and our senior unsecured notes indentures and their supplements also contain a number of covenants, including those that restrict our ability to incur debts, including debts secured by mortgages on our properties, in excess of calculated amounts, require us to comply with certain financial covenants and, in the case of our credit agreement, restrict our ability to make distributions to our shareholders under certain circumstances. As of June 30, 2021, we believe we were in compliance with the terms and conditions of our respective covenants under our credit agreement and senior unsecured notes indentures and their supplements. Our mortgage notes are non-recourse, subject to certain limited exceptions, and do not contain any material financial covenants.

Neither our credit agreement nor our senior unsecured notes indentures and their supplements contain provisions for acceleration which could be triggered by our credit ratings. However, under our credit agreement our highest senior credit rating is used to determine the fees and interest rates we pay. Accordingly, if that credit rating is downgraded, our interest expense and related costs under our credit agreement would increase.

Our credit agreement has cross default provisions to other indebtedness that is recourse of $25,000 or more and indebtedness that is non-recourse of $50,000 or more. Similarly, our senior unsecured notes indentures and their supplements contain cross default provisions to any other debts of more than $25,000 (or up to $50,000 in certain circumstances).

Related Person Transactions

We have relationships and historical and continuing transactions with RMR LLC, RMR Inc. and others related to them. For more information about these and other such relationships and related person transactions, see Notes 9 and 10 to the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q, our 2020 Annual Report, our definitive Proxy Statement for our 2021 Annual Meeting of Shareholders and our other filings with the SEC. In addition, see the section captioned “Risk Factors” of our 2020 Annual Report for a description of risks that may arise as a result of these and other related person transactions and relationships. We may engage in additional transactions with related persons, including businesses to which RMR LLC or its subsidiaries provide management services.

Item 3. Quantitative and Qualitative Disclosures About Market Risk (dollar amounts in thousands, except per share data)

We are exposed to risks associated with market changes in interest rates. We manage our exposure to this market risk by monitoring available financing alternatives. Our strategy to manage exposure to changes in interest rates has not materially changed since December 31, 2020. Other than as described below, we do not currently foresee any significant changes in our exposure to fluctuations in interest rates or in how we manage this exposure in the near future.

Fixed Rate Debt

At June 30, 2021, our outstanding fixed rate debt consisted of the following:

Debt	Principal Balance (1)		Annual Interest Rate (1)	Annual Interest Expense (1)		Maturity	Interest Payments Due
Senior unsecured notes	$	300,000	4.150%	$	12,450	2022	Semi-annually
Senior unsecured notes	300,000		4.000%	12,000		2022	Semi-annually
Senior unsecured notes	350,000		4.250%	14,875		2024	Semi-annually
Senior unsecured notes	650,000		4.500%	29,250		2025	Semi-annually
Senior unsecured notes	300,000		2.650%	7,950		2026	Semi-annually
Senior unsecured notes	162,000		6.375%	10,328		2050	Quarterly
Mortgage note (one property in Washington, D.C.)	25,433		4.220%	1,073		2022	Monthly
Mortgage note (one property in Chicago, IL)	50,000		3.700%	1,850		2023	Monthly
Mortgage note (one property in Washington, D.C.)	23,470		4.800%	1,127		2023	Monthly
Total	$	2,160,903		$	90,903

(1)The principal balances and annual interest rates are the amounts stated in the applicable contracts. In accordance with GAAP, our carrying values and recorded interest expense may differ from these amounts because of market conditions at the time we issued or assumed these debts. For more information, see Notes 6 and 7 to the Notes to Condensed Consolidated Financial Statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Our senior unsecured notes require semi-annual or quarterly interest payments through maturity. Our mortgages generally require principal and interest payments through maturity pursuant to amortization schedules. Because these debts require interest to be paid at a fixed rate, changes in market interest rates during the term of these debts will not affect our interest obligations. If these debts were refinanced at interest rates which are one percentage point higher or lower than shown above, our annual interest cost would increase or decrease by approximately $21,609.

Changes in market interest rates also would affect the fair value of our fixed rate debt obligations; increases in market interest rates decrease the fair value of our fixed rate debt, while decreases in market interest rates increase the fair value of our fixed rate debt. Based on the balances outstanding at June 30, 2021, and discounted cash flow analyses through the respective maturity dates, and assuming no other changes in factors that may affect the fair value of our fixed rate debt obligations, a hypothetical immediate one percentage point increase in interest rates would change the fair value of those obligations by approximately $76,870.

Some of our fixed rate secured debt arrangements allow us to make repayments earlier than the stated maturity date. In some cases, we are not allowed to make early repayment prior to a cutoff date and we are generally allowed to make prepayments only at a premium equal to a make whole amount, as defined, which is generally designed to preserve a stated yield to the note holder. These prepayment rights may afford us opportunities to mitigate the risk of refinancing our debts at maturity at higher rates by refinancing prior to maturity.

33

At June 30, 2021, we owned 51% and 50% interests in two joint venture arrangements which own three properties that are secured by fixed rate debt consisting of the following mortgage notes:

Debt	Our JV Ownership Interest	Principal Balance (1)(2)		Annual Interest Rate (1)	Annual Interest Expense (1)		Maturity	Interest Payments Due
Mortgage note (two properties in Fairfax, VA)	51%	$	50,000	4.090%	$	2,045	2029	Monthly
Mortgage note (one property in Washington, D.C.)	50%	32,000		3.690%	1,181		2024	Monthly
Total		$	82,000		$	3,226

(1)The principal balances and annual interest rates are the amounts stated in the applicable contracts. In accordance with GAAP, the joint ventures’ recorded interest expense may differ from these amounts because of market conditions at the time they incurred the debt.

(2)Reflects the entire balance of the debt secured by the properties and is not adjusted to reflect the interests in the joint ventures we do not own. None of the debt is recourse to us.

Floating Rate Debt

At June 30, 2021, we had $385,000 of outstanding floating rate debt under our revolving credit facility. Our revolving credit facility matures on January 31, 2023 and, subject to the payment of an extension fee and meeting certain other conditions, we have the option to extend the stated maturity by two six month periods. No principal repayments are required under our revolving credit facility prior to maturity, and we can borrow, repay and reborrow funds available under our revolving credit facility, subject to conditions, at any time without penalty.

Borrowings under our revolving credit facility are in U.S. dollars and require interest to be paid at a rate of LIBOR plus premiums that are subject to adjustment based upon changes to our credit ratings. Accordingly, we are vulnerable to changes in U.S. dollar based short term rates, specifically LIBOR, and to changes in our credit ratings. In addition, upon renewal or refinancing of our revolving credit facility, we are vulnerable to increases in interest rate premiums due to market conditions or our perceived credit characteristics. Generally, a change in interest rates would not affect the value of our floating rate debt but would affect our operating results.

The following table presents the impact a one percentage point increase in interest rates would have on our annual floating rate interest expense as of June 30, 2021:

	Impact of an Increase in Interest Rates
	Annual Interest Rate (1)		Outstanding Debt		Total Interest Expense Per Year		Annual Earnings Per Share Impact (2)
At June 30, 2021	1.2	%	$	385,000	$	4,620	$	0.10
One percentage point increase	2.2	%	$	385,000	$	8,470	$	0.18

(1)Weighted based on the interest rates and outstanding borrowings under our revolving credit facility as of June 30, 2021. 

(2)Based on the weighted average shares outstanding (diluted) for the six months ended June 30, 2021.

The following table presents the impact a one percentage point increase in interest rates would have on our annual floating rate interest expense as of June 30, 2021 if we were fully drawn on our revolving credit facility:

	Impact of an Increase in Interest Rates
	Annual Interest Rate (1)		Outstanding Debt		Total Interest Expense Per Year		Annual Earnings Per Share Impact (2)
At June 30, 2021	1.2	%	$	750,000	$	9,000	$	0.19
One percentage point increase	2.2	%	$	750,000	$	16,500	$	0.34

(1)Weighted based on the interest rates and outstanding borrowings under our revolving credit facility (assuming fully drawn) as of June 30, 2021. 

(2)Based on the weighted average shares outstanding (diluted) for the six months ended June 30, 2021.

The foregoing tables show the impact of an immediate increase in floating interest rates as of June 30, 2021. If interest rates were to increase gradually over time, the impact would be spread over time. Our exposure to fluctuations in floating interest rates will increase or decrease in the future with increases or decreases in the outstanding amount under our revolving credit facility or our other floating rate debt, if any. Although we have no present plans to do so, we may in the future enter into hedge arrangements from time to time to mitigate our exposure to changes in interest rates.

34

LIBOR Phase Out

LIBOR is currently expected to be phased out for new contracts by December 31, 2021 and for pre-existing contracts by June 30, 2023. We are required to pay interest on borrowings under our revolving credit facility at a floating rate based on LIBOR. Interest we may pay on any future debt that we may incur may also require that we pay interest based upon LIBOR. We currently expect that the determination of interest under our revolving credit facility would be revised as provided under our credit agreement or amended as necessary to provide for an interest rate that approximates the existing interest rate as calculated in accordance with LIBOR. Despite our current expectations, we cannot be sure that, if LIBOR is phased out or transitioned, the changes to the determination of interest under our agreements would approximate the current calculation in accordance with LIBOR. We do not know what standard, if any, will replace LIBOR if it is phased out or transitioned.

Item 4. Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, our management carried out an evaluation, under the supervision and with the participation of our Managing Trustees, our President and Chief Operating Officer and our Chief Financial Officer and Treasurer, of the effectiveness of our disclosure controls and procedures pursuant to Rules 13a-15 and 15d-15 under the Securities Exchange Act of 1934, as amended. Based upon that evaluation, our Managing Trustees, our President and Chief Operating Officer and our Chief Financial Officer and Treasurer concluded that our disclosure controls and procedures are effective.

There have been no changes in our internal control over financial reporting during the quarter ended June 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Warning Concerning Forward-Looking Statements

This Quarterly Report on Form 10-Q contains statements that constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and other securities laws. Also, whenever we use words such as “believe”, “expect”, “anticipate”, “intend”, “plan”, “estimate”, “will”, “may” and negatives or derivatives of these or similar expressions, we are making forward-looking statements. These forward-looking statements are based upon our present intent, beliefs or expectations, but forward-looking statements are not guaranteed to occur and may not occur. Forward-looking statements in this Quarterly Report on Form 10-Q relate to various aspects of our business, including:

•The duration and severity of the COVID-19 pandemic and its impact on us and our tenants and our tenants’ ability and willingness to pay us rent,

•Our expectations about the financial strength of our tenants,

•The likelihood that our rents will increase when we renew or extend our leases or enter new leases,

•Our belief that we are in a position to opportunistically recycle and deploy capital,

•Our expectations that the diversity and other characteristics of our property portfolio and our financial resources will result in our ability to successfully withstand the current economic conditions,

•The likelihood that our tenants will renew or extend their leases and not exercise early termination options pursuant to their leases or that we will obtain replacement tenants, on terms as favorable to us as our prior leases,

•The likelihood that our tenants will be negatively affected by cyclical economic conditions or government budget constraints and, if so, the impact that may have on their ability and willingness to lease our properties and pay us rent,

•Our ability to successfully execute our capital recycling program,

•The expectation that, as a result of the COVID-19 pandemic, leasing activity may remain volatile until office property market conditions meaningfully improve and stabilize,

•Our ability to pay distributions to our shareholders and to maintain or increase the amount of such distributions,

•Our expectations regarding occupancy at our properties,

•Our expectations regarding our future financial performance including FFO, Normalized FFO or NOI,

•Our expectations regarding demand for leased space,

35

•Our expectations regarding capital expenditures,

•Our expectation that there will be opportunities for us to acquire, and that we will acquire, additional properties primarily leased to single tenants and tenants with high credit quality characteristics such as government entities,

•Our expectations regarding the costs and timing of our redevelopment projects,

•Our ability to compete for acquisitions and tenancies effectively,

•Our sales and acquisitions of properties,

•Our policies and plans regarding investments, financings and dispositions,

•Our ability to appropriately balance our use of debt and equity capital,

•The future availability of borrowings under our revolving credit facility,

•Our ability to raise debt or equity capital,

•Our ability to pay interest on and principal of our debt,

•Our ability to maintain sufficient liquidity during the duration of the COVID-19 pandemic and any resulting economic downturn,

•Our credit ratings,

•Our expectation that we benefit from our relationships with RMR LLC,

•The credit qualities of our tenants,

•Our qualification for taxation as a REIT,

•Changes in federal or state tax laws, and

•Other matters.

Our actual results may differ materially from those contained in or implied by our forward-looking statements. Forward-looking statements involve known and unknown risks, uncertainties and other factors, some of which are beyond our control. Risks, uncertainties and other factors that could have a material adverse effect on our forward-looking statements and upon our business, results of operations, financial condition, FFO, Normalized FFO, NOI, cash flows, liquidity and prospects include, but are not limited to:

•The impact of conditions in the economy, including the COVID-19 pandemic and its aftermath, and the capital markets on us and our tenants,

•Competition within the real estate industry, particularly in those markets in which our properties are located,

•The impact of changes in the real estate needs and financial conditions of our tenants,

•Compliance with, and changes to, federal, state and local laws and regulations, accounting rules, tax laws and similar matters,

•The impact of any U.S. government shutdown on our ability to collect rents or pay our operating expenses, debt obligations and distributions to shareholders on a timely basis,

•Actual and potential conflicts of interest with our related parties, including our Managing Trustees, RMR LLC, Sonesta and others affiliated with them,

•Limitations imposed on our business and our ability to satisfy complex rules in order for us to maintain our qualification for taxation as a REIT for U.S. federal income tax purposes, and

•Acts of terrorism, outbreaks of pandemics, including the COVID-19 pandemic, or other manmade or natural disasters beyond our control.

36

For example:

•Our ability to make future distributions to our shareholders and to make payments of principal and interest on our indebtedness depends upon a number of factors, including our receipt of rent from our tenants, our future earnings, the capital costs we incur to lease our properties and our working capital requirements. We may be unable to pay our debt obligations or to maintain our current rate of distributions on our common shares and future distributions may be reduced or eliminated,

•Our ability to grow our business and increase our distributions depends in large part upon our ability to buy properties and lease them for rents, less their property operating costs, that exceed our capital costs. We may be unable to identify properties that we want to acquire, and we may fail to reach agreement with the sellers and complete the purchases of any properties we want to acquire. In addition, any properties we may acquire may not provide us with rents less property operating costs that exceed our capital costs or achieve our expected returns,

•We may fail to maintain, or we may elect to change our distribution rate. Our Board of Trustees considers many factors when setting distribution rates, including our historical and projected income, Normalized FFO, CAD, the then current and expected needs and availability of cash to pay our obligations and fund our investments, distributions which may be required to be paid to maintain our qualification for taxation as a REIT and other factors deemed relevant by our Board of Trustees. Accordingly, future distribution rates may be increased or decreased and there is no assurance as to the rate at which future distributions will be paid,

•We expect to selectively sell properties from time to time when we determine our continued ownership or ongoing required capital expenditures will not achieve desired returns or when we believe we can successfully pursue more desirable opportunities than retaining those properties. We cannot be sure we will sell any of these properties or what the terms of any sales may be or that we will acquire replacement properties that improve our asset quality or our ability to increase our distributions to shareholders,

•We may not succeed in maintaining our leverage consistent with our current investment grade ratings or levels that the market or credit rating agencies believe are appropriate,

•Some of our tenants may not renew expiring leases or they may exercise their rights, if any, to vacate their space before the stated expirations of their leases, and we may be unable to obtain new tenants to maintain or increase the historical occupancy rates of, or rents from, our properties,

•Rents that we can charge at our properties may decline upon renewals or expirations because of changing market conditions or otherwise,

•Leasing for some of our properties depends on a private sector single tenant and we may be adversely affected by the bankruptcy, insolvency, a downturn of business or a lease termination of such single tenant,

•Our belief that there is a likelihood that tenants may renew or extend our leases prior to their expirations whenever they have made significant investments in the leased properties, or because those properties may be of strategic importance to them, may not be realized,

•Overall new leasing volume may decrease more than we currently expect. In addition, if the COVID-19 pandemic and any resulting economic downturn continue for an extended period or worsen, our tenants may become unable to pay rent or they may elect to not renew their leases with us. Further, some of our government leases provide the tenant with certain rights to terminate their lease early. Budgetary and other fiscal pressures may result in some governmental tenants terminating their leases early or not renewing their leases. In addition, the COVID-19 pandemic has caused changes in workplace practices, including increased remote work arrangements. To the extent those practices become permanent or increased, leasing demand for office space may decline. As a result of these factors, our tenant retention levels could decline and we may experience reduced rent or incur increased costs under future new or renewal leases,

•Our belief that we are well positioned to opportunistically recycle and deploy capital may not be realized. We may fail to identify and execute on opportunities to deploy capital and any deployment of capital we may make may not result in the returns that we expect,

•Our perception that, as a result of the COVID-19 pandemic, government tenants may seek to manage space utilization rates in order to provide greater physical distancing for employees, may prove incorrect,

37

•Our perception that activity prior to the outbreak of the COVID-19 pandemic suggested that the government had begun to shift its leasing strategy to include longer term leases and that the government was actively exploring 10 to 20 year lease terms at renewal, in some instances, may mistakenly imply that these activities are indicative of a trend or broader change in government leasing strategy or practices that will recommence after the COVID-19 pandemic ends. Further, even if such a trend or change were to recommence, that trend or change may not be sustained by the government,

•Contingencies in our acquisition and sale agreements may not be satisfied and any expected acquisitions and sales and any related lease arrangements we expect to enter may not occur, may be delayed or the terms of such transactions or arrangements may change,

•We expect to pursue accretively growing our property portfolio. However, we may not succeed in making acquisitions that are accretive and future acquisitions could be dilutive,

•The competitive advantages we believe we have may not in fact exist or provide us with the advantages we expect. We may fail to maintain any of these advantages or our competition may obtain or increase their competitive advantages relative to us,

•We intend to conduct our business activities in a manner that will afford us reasonable access to capital for investment and financing activities. However, we may not succeed in this regard and we may not have reasonable access to capital,

•Continued availability of borrowings under our revolving credit facility is subject to our satisfying certain financial covenants and other credit facility conditions that we may be unable to satisfy,

•Actual costs under our revolving credit facility will be higher than LIBOR plus a premium because of fees and expenses associated with such debt,

•The interest rates payable under our floating rate debt obligations depend upon our credit ratings. If our credit ratings are downgraded, our borrowing costs will increase,

•Our ability to access debt capital and the cost of our debt capital will depend in part on our credit ratings. If our credit ratings are downgraded, we may not be able to access debt capital or the debt capital we can access may be expensive,

•We may be unable to repay our debt obligations when they become due,

•The maximum borrowing availability under our revolving credit facility may be increased to up to $1.95 billion in certain circumstances; however, increasing the maximum borrowing availability under our revolving credit facility is subject to our obtaining additional commitments from lenders, which may not occur,

•We have the option to extend the maturity date of our revolving credit facility upon payment of a fee and meeting other conditions; however, the applicable conditions may not be met,

•We may incur significant costs to prepare a property for tenancy, particularly for single tenant properties,

•We may spend more for capital expenditures than we currently expect,

•We may fail to obtain development rights or entitlements that we may seek for development and other projects we may wish to conduct at our properties,

•Our existing joint venture arrangements and any other joint venture arrangements that we may enter may not be successful,

•Any redevelopment projects we undertake may be unsuccessful, may require greater capital expenditures or other costs than we project or may take significant time to complete,

•We believe that we are well positioned to weather the present disruptions of the COVID-19 pandemic facing the real estate industry. However, the full extent of the future impact of the COVID-19 pandemic is unknown and we may not realize similar or better operating results in the future,

•We believe that the near term impact of the COVID-19 pandemic to us will not be material due to the strength of our tenant base. However, if the COVID-19 pandemic and any resulting economic downturn continue for an extended

38

period of time or worsen, our tenants may be significantly adversely impacted, which may result in those tenants seeking relief from their rent obligations, their inability to pay rent, the termination of their leases or our tenants not renewing their leases or renewing their leases for less space. Therefore, the impact we experience in the near term may be worse than we currently expect and our results of operations and financial position may be negatively affected,

•We have granted requests to some of our tenants to defer payments over, in most cases, a 12-month period, all of which have commenced. However, current market and economic conditions may deteriorate further and the rent assistance granted by us may not be sufficient to ensure that tenants will be able to meet their rent payment obligations under their leases with us, which may result in an increase in tenant defaults and terminations,

•The business and property management agreements between us and RMR LLC have continuing 20 year terms. However, those agreements permit early termination in certain circumstances. Accordingly, we cannot be sure that these agreements will remain in effect for continuing 20 year terms,

•We believe that our relationships with our related parties, including RMR LLC, Sonesta and others affiliated with them, may benefit us and provide us with competitive advantages in operating and growing our business. However, the advantages we believe we may realize from these relationships may not materialize, and

•It is difficult to accurately estimate leasing related obligations and costs of property repositioning, development, redevelopment and tenant improvement costs. Our unspent leasing related obligations and development or redevelopment costs may cost more and may take longer to complete than we currently expect, and we may incur increased amounts for these and similar purposes in the future.

Currently unexpected results could occur due to many different circumstances, some of which are beyond our control, such as the COVID-19 pandemic and its aftermath, changes in our tenants’ needs for leased space, the ability of the U.S. and state governments to approve spending bills to fund their obligations, acts of terrorism, natural disasters or changes in capital markets or the economy generally.
