DIVERSIFIED HEALTHCARE TRUST
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
(dollar amounts in thousands, except per share data or as otherwise stated)
Note 1. Basis of Presentation
The accompanying condensed consolidated financial statements of Diversified Healthcare Trust and its subsidiaries, or 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, 2019, or our 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. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.
The preparation of 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 our condensed consolidated financial statements include purchase price allocations, useful lives of fixed assets and impairments of real estate and intangible assets. We have made reclassifications to the financial statements of prior periods to conform to the current period presentation. These reclassifications had no effect on net income (loss) or equity.
We have a joint venture arrangement with an institutional investor for one of our life science properties located in Boston, Massachusetts. The investor owns a 45% equity interest in the joint venture, and we own the remaining 55% equity interest in the joint venture. We have determined that this joint venture is a variable interest entity, or VIE, as defined under the Consolidation Topic of the Financial Accounting Standards Board, or FASB, Accounting Standards Codification. We concluded that we must consolidate this VIE because we are the entity with the power to direct the activities that most significantly impact the VIE's economic performance and we have the obligation to absorb losses of, and the right to receive benefits from, the VIE that could be significant to the VIE, and therefore are the primary beneficiary of the VIE. The assets of this VIE were $991,730 and $1,015,661 as of June 30, 2020 and December 31, 2019, respectively, and consist primarily of the net real estate owned by the joint venture. The liabilities of this VIE were $699,761 and $704,344 as of June 30, 2020 and December 31, 2019, respectively, and consist primarily of the secured debts on the property. The investor's interest in this consolidated entity is reflected as a noncontrolling interest in our condensed consolidated financial statements. See Note 7 for further information about this joint venture.
Note 2. Recent Accounting Pronouncements
In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires that entities use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for credit losses. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. We adopted this standard which was effective as of January 1, 2020 using the modified retrospective approach. The implementation of this standard did not have a material impact in our condensed consolidated financial statements.
Note 3. Real Estate Properties
As of June 30, 2020, we owned 412 properties located in 38 states and Washington, D.C., including 21 properties classified as held for sale and one life science property owned in a joint venture arrangement in which we own a 55% equity interest.
We regularly evaluate our assets for indicators of impairment. Impairment indicators may include declining tenant or resident occupancy, weak or declining profitability from the property, decreasing tenant cash flows or liquidity, our decision to dispose of an asset before the end of its estimated useful life, and legislative, market or industry changes that could permanently reduce the value of an asset. If indicators of impairment are present, we evaluate the carrying value of the affected assets by comparing it to the expected future cash flows to be generated from those assets. The future cash flows are subjective and are

Table of Contents
DIVERSIFIED HEALTHCARE TRUST
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
(dollar amounts in thousands, except per share data or as otherwise stated)
based in part on assumptions regarding hold periods, market rents and terminal capitalization rates. If the sum of these expected future cash flows is less than the carrying value, we reduce the net carrying value of the asset to its estimated fair value.
Acquisition Activities:
In January 2020, we acquired a vacant land parcel adjacent to a property we own in our portfolio of medical office and life science properties, or our Office Portfolio, segment located in Tempe, Arizona for $2,600, excluding acquisition costs.
Disposition Activities:
During the six months ended June 30, 2020, we sold 12 properties for an aggregate sales price of $68,154, excluding closing costs, as presented in the table below. The sales of these properties do not represent significant dispositions individually or in the aggregate, nor do we believe they represent a strategic shift in our business. As a result, the results of the operation for these properties are included in continuing operations through the date of sale of such properties in our condensed consolidated statements of comprehensive income (loss).

Date of Sale |  | Location |  | Type of Property |  | Number of Properties |  | Square Feet or Number of Units |  |  | Sales Price (1) |  | Gain (loss) on Sale |  | Impairment of Assets
January 2020 |  | Louisiana |  | Medical Office |  | 6 |  | 40,575 |  | sq. ft. |  | $ | 5,925 |  |  | $ | (81 | ) |  | $ | — |

April 2020 |  | California |  | Managed Senior Living |  | 3 |  | 599 |  | units |  | 47,000 |  |  | (168 | ) |  | 5,465 |

|  |  |  |  |  | 12 |  |  |  |  | $ | 68,154 |  |  | $ | 2,614 |  |  | $ | 8,171 |

(1) | Sales price excludes closing costs.

As of June 30, 2020, we had 21 properties classified as held for sale in our condensed consolidated balance sheet as follows:

Type of Property |  | Number of Properties |  | Undepreciated Carrying Value |  | Impairment of Assets(1)
Managed Senior Living |  | 15 |  | $ | 52,563 |  |  | $ | 30,752 |
Medical Office |  | 3 |  | 11,832 |  |  | 415 |
Triple Net Leased, Senior Living |  | 3 |  | 48,236 |  |  | — |
|  | 21 |  | $ | 112,631 |  |  | $ | 31,167 |

(1) | We recorded an aggregate of $31,167 impairment of real estate during the six months ended June 30, 2020 to adjust the carrying values of certain of these properties to their estimated fair values less costs to sell.

Subsequent to June 30, 2020, two of the three medical office properties and two of the 15 managed senior living communities classified as held for sale in the table above were sold for an aggregate sales price of $5,197, excluding closing costs.
We also recorded impairment charges of $3,071 related to seven medical office properties and two senior living communities that were classified as held for sale during the three months ended March 31, 2020. These properties were subsequently reclassified to held and used as of June 30, 2020.
As of August 3, 2020, we had 24 properties under agreements to sell for an aggregate sales price of approximately $231,725, excluding closing costs. We may not complete the sales of any or all of the properties we currently plan to sell. Also, we may sell some or all of these properties at amounts that are less than currently expected and/or less than the carrying values of such properties and we may incur losses on any such sales as a result.

Note 4. Leases
We are a lessor of medical office and life science properties, senior living communities and other healthcare related properties. Our leases provide our tenants with the contractual right to use and economically benefit from all of the premises demised under the leases; therefore, we have determined to evaluate our leases as lease arrangements.
Certain of 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.
We increased rental income to record revenue on a straight line basis by $1,385 and $430 for the three months ended June 30, 2020 and 2019, respectively, and $2,538 and $2,364 for the six months ended June 30, 2020 and 2019, respectively. Rents receivable, excluding properties classified as held for sale, include $107,178 and $99,297 of straight line rent receivables at June 30, 2020 and December 31, 2019, respectively, and are included in other assets, net in our condensed consolidated balance sheets.
We do not include in our measurement of our lease receivables certain variable payments, including 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. We recognized such payments totaling $18,263 and $19,525 for the three months ended June 30, 2020 and 2019, respectively, of which tenant reimbursements totaled $1,074 and $1,203, respectively, and $38,291 and $38,370 for the six months ended June 30, 2020 and 2019, respectively, of which tenant reimbursements totaled $2,094 and $2,400, respectively.
As a result of the COVID-19 pandemic, some of our tenants have requested relief from their obligations to pay rent due to us. As of August 3, 2020, we granted requests for certain of our tenants to defer rent payments totaling $5,474. These tenants are obligated to pay, in most cases, the deferred rents in 12 equal monthly installments commencing in September 2020. We have elected to use the FASB relief package regarding the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. The FASB relief package provides entities with the option to account for lease concessions resulting from the COVID-19 pandemic outside of the existing lease modification guidance if the resulting cash flows from the modified lease are substantially the same as the original lease. Because the majority of the deferred rents referenced above will generally be repaid over a 12-month period, the cash flows from the respective leases are substantially the same as before the rent deferrals. These deferred amounts did not negatively impact our results for the three and six months ended June 30, 2020 and, as of June 30, 2020, we recognized an increase in our accounts receivable related to these deferred amounts of $3,504.
Right of Use Asset and Lease Liability. For leases where we are the lessee, we recognized a right of use asset and a lease liability equal to the present value of the minimum lease payments with rental payments being applied to the lease liability and the right of use asset being amortized over the term of the lease. The value of the right of use asset and related liability representing our future obligation under the lease arrangement for which we are the lessee were $4,278 and $4,437, respectively, as of June 30, 2020, and $4,319 and $4,461, respectively, as of December 31, 2019. The right of use asset and related lease liability are included within other assets, net and other liabilities, respectively, within our condensed consolidated balance sheets. In addition, we lease equipment at certain of our managed senior living communities. These leases are short term in nature, are cancelable with no fee or do not result in an annual expense in excess of our capitalization policy and, as a result, are not recorded on our condensed consolidated balance sheets.

Note 5. Indebtedness
Our principal debt obligations at June 30, 2020 were: (1) $2,650,000 outstanding principal amount of senior unsecured notes; (2) $200,000 outstanding principal amount under our term loan; and (3) $685,428 aggregate principal amount of mortgage notes (excluding premiums, discounts and net debt issuance costs) secured by seven properties, of which $620,000 is related to a joint venture arrangement in which we own a 55% equity interest. These seven mortgaged properties had a gross book value of real estate assets at cost plus certain acquisition costs, before depreciation and purchase price allocations and less impairment write downs of $1,258,457 at June 30, 2020. We also had two properties subject to finance leases with lease obligations totaling $8,352 at June 30, 2020; these two properties had gross book value of real estate assets of $35,708 at June 30, 2020, and the finance leases expire in 2026.
We have a $1,000,000 unsecured revolving credit facility that is available for general business purposes. The maturity date of our revolving credit facility is January 15, 2022, and, subject to the payment of an extension fee and meeting other conditions, we have the option to extend the maturity date of the facility for an additional year. Our revolving credit facility provides that we can borrow, repay and re-borrow funds available under our revolving credit facility until maturity, and no principal repayment is due until maturity. As of June 30, 2020, our revolving credit facility required interest to be paid on borrowings at the annual rate of 2.6%, plus a facility fee of 30 basis points per annum on the total amount of lending commitments under the facility.
The weighted average annual interest rates for borrowings under our revolving credit facility were 1.8% and 3.6% for the three months ended June 30, 2020 and 2019, respectively, and 2.2% and 3.6% for the six months ended June 30, 2020 and 2019, respectively. The interest rate premium and facility fee are each subject to adjustment based upon changes to our credit ratings. As of June 30, 2020 and August 3, 2020, we had no outstanding borrowings and $1,000,000 available for borrowing under our revolving credit facility.
We have a $200,000 unsecured term loan that matures in September 2022 and is prepayable without penalty at any time. At June 30, 2020, the annual interest rate payable on amounts outstanding under this term loan was 2.4%. The weighted average annual interest rate for amounts outstanding under this term loan was 2.3% and 3.9% for the three months ended June 30, 2020 and 2019, respectively, and 2.7% and 3.9% for the six months ended June 30, 2020 and 2019, respectively. The interest rate premium is subject to adjustment based upon changes to our credit ratings.
In February 2020, we prepaid a mortgage note secured by one of our life science properties with an outstanding principal balance of approximately $1,554, a maturity date in March 2026 and an annual interest rate of 6.25%. As a result of this prepayment, we recorded a loss on early extinguishment of debt of $246 for the six months ended June 30, 2020. We prepaid this mortgage using cash on hand and borrowings under our revolving credit facility.
In April 2020, we redeemed all of our outstanding 6.75% senior notes due 2020 for a redemption price equal to the principal amount of $200,000 plus accrued and unpaid interest of $6,750. We funded this redemption with cash on hand and borrowings under our revolving credit facility.
In May 2020, we prepaid a mortgage note secured by one of our medical office properties with an outstanding principal balance of approximately $1,213, a maturity date in January 2022 and an annual interest rate of 7.49%. As a result of the prepayment of this mortgage note, we recorded a loss on early extinguishment of debt of $155 for both the three and six months ended June 30, 2020. We prepaid this mortgage using cash on hand and borrowings under our revolving credit facility.
In June 2020, we issued $1,000,000 aggregate principal amount of our 9.75% senior notes due 2025 in an underwritten public offering raising net proceeds of $983,500, after deducting estimated offering expenses and underwriters' discounts. These notes are guaranteed by all of our subsidiaries, except for certain excluded subsidiaries, and require semi-annual interest payments through maturity. Prior to June 15, 2022, we may, at our option, redeem all or a portion of these notes at a redemption price equal to the outstanding principal amount of these notes, plus accrued and unpaid interest, plus the make-whole amount set forth in the indenture which governs these notes, as supplemented, or our 2025 Notes Indenture. Prior to June 15, 2022, we may also, at our option, redeem up to 40% of the aggregate principal amount of these notes with the net proceeds of certain equity offerings at the redemption price set forth in the 2025 Notes Indenture, so long as at least 50% of the original aggregate principal amount of these notes remains outstanding after each such redemption. In addition, we have the option to redeem all or a portion of these notes at any time on or after June 15, 2022 at the redemption prices set forth in the 2025 Notes Indenture. We used the net proceeds from this offering to prepay in full our $250,000 unsecured term loan which was scheduled to mature

in June 2020 and to reduce amounts outstanding under our revolving credit facility. The weighted average interest rate under our $250,000 senior unsecured term loan was 1.9% and 2.4% for the periods from April 1, 2020 to June 2, 2020 and January 1, 2020 to June 2, 2020, respectively. As a result of the repayment of our $250,000 senior unsecured term loan, we recorded a loss on early extinguishment of debt of $26 for the three and six months ended June 30, 2020.
In June 2020, we amended the agreements governing our $1,000,000 unsecured revolving credit facility and $200,000 unsecured term loan, or collectively, our credit and term loan agreements. The amendments modify certain of the financial covenants under our credit and term loan agreements through June 30, 2021, or the Amendment Period, during which, subject to certain conditions, we will continue to have access to undrawn amounts under our revolving credit facility. We have the right to terminate the Amendment Period prior to June 30, 2021, subject to certain conditions.
During the Amendment Period:

• | our interest rate premium over LIBOR under our revolving credit facility and term loan increased by 50 basis points;

• | we will generally be required to apply the net cash proceeds from the disposition of assets, capital markets transactions, debt financings or COVID-19 government stimulus programs, if allowed, to the repayment of outstanding loans under the revolving credit facility, if any;

• | we will be subject to certain additional covenants, including additional restrictions on our ability to incur indebtedness (with exceptions for borrowings under our revolving credit facility and certain other categories of secured and unsecured indebtedness), and to acquire real property or make other investments (with exceptions for, among other things, certain categories of capital expenditures and costs);

• | we will be required to maintain unrestricted liquidity (unrestricted cash and undrawn availability under our revolving credit facility) of not less than $200,000; and

• | our ability to pay distributions on our common shares will be limited to paying a cash dividend of $0.01 per common share per quarter and amounts required to maintain our qualification for taxation as a real estate investment trust, or REIT, and to avoid the payment of certain income and excise taxes.

Our credit and term loan agreements and our 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 and term loan agreements, a change of control of us, as defined, which includes The RMR Group LLC, or RMR LLC, ceasing to act as our business and property manager. Our credit and term loan agreements and our senior unsecured notes indentures and their supplements also contain covenants, including covenants that restrict our ability to incur debts, and generally require us to maintain certain financial ratios, and our credit and term loan agreements 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 and term loan agreements and our senior unsecured notes indentures and their supplements at June 30, 2020. Although we have taken steps to enhance our ability to maintain sufficient liquidity, as noted elsewhere in this Quarterly Report on Form 10-Q, a protracted negative economic impact resulting from the COVID-19 pandemic may cause increased pressure on our ability to satisfy financial and other covenants.

Note 6. Fair Value of Assets and Liabilities
The following table presents certain of our assets that are measured at fair value at June 30, 2020, categorized by the level of inputs as defined in the fair value hierarchy under GAAP, used in the valuation of each asset.

|  |  |  | Fair Value at Reporting Date Using

Real estate properties held for sale (2) |  | $ | 52,957 |  |  | $ | — |  |  | $ | 52,957 |  |  | $ | — |

(1) | Our 10,691,658 shares of common stock of Five Star Senior Living Inc., or Five Star, are included in other assets, net in our condensed consolidated balance sheets, and are reported at fair value, which is based upon quoted market prices on The Nasdaq Stock Market LLC, or Nasdaq, (Level 1 inputs). On April 1, 2019, we entered into a transaction agreement with Five Star, or the Transaction Agreement, to restructure our business arrangements with Five Star, or the Restructuring Transaction. Pursuant to the Transaction Agreement, on January 1, 2020, Five Star issued 10,268,158 Five Star common shares to us. The fair value and initial cost basis of the Five Star common shares issued to us on January 1, 2020 was $38,095. Our adjusted cost basis inclusive of the 423,500 Five Star common shares we owned as of December 31, 2019 and the 10,268,158 Five Star common shares issued to us on January 1, 2020 was $44,448 as of June 30, 2020. During the three and six months ended June 30, 2020, we recorded unrealized gains of $11,974 and $2,031, respectively, which is included in gains and losses on equity securities, net in our condensed consolidated statements of comprehensive income (loss), to adjust the carrying value of our investment in Five Star common shares to their fair value. See Note 12 for further information about our investment in Five Star.

(2) | We have assets in our condensed consolidated balance sheets that are measured at fair value on a nonrecurring basis. During the six months ended June 30, 2020, we recorded impairment charges of $267 to reduce the carrying value of one medical office property that is classified as held for sale to its estimated sales price, less estimated costs to sell of $84, based on the sales price under a purchase and sale agreement that we have entered into with a third party buyer for this medical office property of $625. We also recorded impairment charges of $30,752 to reduce the carrying value of 15 senior living communities that are classified as held for sale to their estimated sales price, less estimated costs to sell of $1,184, based on the aggregate sales prices under the purchase and sale agreements that we have entered into with third party buyers for these senior living communities of $53,600. See Note 3 for further information about impairment charges and these and other properties we have classified as held for sale.

In addition to the assets described in the table above, our financial instruments at June 30, 2020 and December 31, 2019 included cash and cash equivalents, restricted cash, other assets, our revolving credit facility, term loans, senior unsecured notes, secured debt and finance leases and other unsecured obligations and liabilities. The fair values of these financial instruments approximated their carrying values in our condensed consolidated financial statements as of such dates, except as follows:

|  | As of June 30, 2020 |  | As of December 31, 2019
Description |  | Carrying Amount (1) |  | Estimated Fair Value |  | Carrying Amount (1) |  | Estimated Fair Value

(2) | We assumed certain of these secured debts in connection with our acquisition of certain properties. We recorded the assumed mortgage notes at estimated fair value on the date of acquisition and we are amortizing the fair value adjustments, if any, to interest expense over the respective terms of the mortgage notes to adjust interest expense to the estimated market interest rates as of the date of acquisition.

We estimated the fair value of our two issuances of senior unsecured notes due 2042 and 2046 based on the closing price on Nasdaq (Level 1 input) as of June 30, 2020. We estimated the fair values of our four issuances of senior unsecured notes due 2021, 2024, 2025 and 2028 using an average of the bid and ask price on Nasdaq on or about June 30, 2020 (Level 2 inputs as defined in the fair value hierarchy under GAAP). We estimated the fair values of our secured debts by using discounted cash flows analyses and currently prevailing market terms as of the measurement date (Level 3 inputs as defined in the fair value hierarchy under GAAP). Because Level 3 inputs are unobservable, our estimated fair values may differ materially from the actual fair values.
Realized and unrealized gains and losses for our equity securities for the three and six months ended June 30, 2020 and 2019 were as follows:

|  | Three Months Ended June 30, |  | Six Months Ended June 30,
|  | 2020 |  | 2019 |  | 2020 |  | 2019
Realized gains and losses on equity securities sold (1) |  | $ | — |  |  | $ | (62,272 | ) |  | $ | — |  |  | $ | (41,436 | )
Unrealized gains and losses on equity securities held |  | 11,974 |  |  | (2,176 | ) |  | 2,031 |  |  | (80 | )
Gains and losses on equity securities, net |  | $ | 11,974 |  |  | $ | (64,448 | ) |  | $ | 2,031 |  |  | $ | (41,516 | )

(1) | This amount relates to our sale of our former investment in The RMR Group Inc., or RMR Inc., on July 1, 2019. For further information about our former investment in RMR Inc. see our Annual Report.

Note 7. Noncontrolling Interest
We have a joint venture arrangement with an institutional investor for one of our life science properties located in Boston, Massachusetts. The investor owns a 45% equity interest in the joint venture, and we own the remaining 55% equity interest in the joint venture. We continue to control this property and therefore continue to account for this property on a consolidated basis in our condensed consolidated financial statements under the VIE model. The portion of the joint venture's net income and comprehensive income not attributable to us, or $1,330 and $1,413 for the three months ended June 30, 2020 and 2019, respectively, and $2,738 and $2,835 for the six months ended June 30, 2020 and 2019, respectively, is reported as a noncontrolling interest in our condensed consolidated statements of comprehensive income (loss). The joint venture made aggregate cash distributions to the other joint venture investor of $5,616 and $5,684 for the three months ended June 30, 2020 and 2019, respectively, and $11,383 and $11,187 for the six months ended June 30, 2020 and 2019, respectively, which are reflected as a decrease in total equity attributable to noncontrolling interest in our condensed consolidated balance sheets. As of June 30, 2020, this joint venture held real estate assets with an aggregate net book value of $714,906, subject to mortgage notes of $620,000.
In assessing whether we have a controlling interest in this joint venture arrangement and are required to consolidate the accounts of the joint venture entity, we considered the members' rights to residual gains and obligations to absorb losses, which activities most significantly impact the economic performance of the entity and which member has the power to direct those activities.

Note 8. Shareholders' Equity
Common Share Awards:
On May 19, 2020, in accordance with our Trustee compensation arrangements, we awarded to each of our six Trustees 10,000 of our common shares, valued at $2.94 per share, the closing price of our common shares on Nasdaq on that day.
Common Share Purchases:
During the six months ended June 30, 2020, we purchased our common shares from certain former officers and employees of RMR LLC in satisfaction of tax withholding and payment obligations in connection with the vesting of awards of our common shares, valued at the closing price of our common shares on Nasdaq on the purchase dates, as follows:

Date Purchased |  | Number of Shares |  | Price per Share
1/9/2020 |  | 1,938 |  |  | $ | 8.10 |
3/13/2020 |  | 1,500 |  |  | $ | 3.79 |
6/30/2020 |  | 1,757 |  |  | $ | 4.43 |

Distributions:
During the six months ended June 30, 2020, we declared and paid quarterly distributions to common shareholders as follows:

Record Date |  | Payment Date |  | Distribution Per Share |  | Total Distributions
January 27, 2020 |  | February 20, 2020 |  | $ | 0.15 |  |  | $ | 35,684 |
April 13, 2020 |  | May 21, 2020 |  | $ | 0.01 |  |  | $ | 2,379 |

As described in Note 10, pursuant to the Transaction Agreement, on January 1, 2020, Five Star issued an aggregate of 16,118,849 of its common shares, with a value of $59,801, to our shareholders of record as of December 13, 2019. We recorded this issuance as a non-cash distribution in our condensed consolidated financial statements.
On July 16, 2020, we declared a quarterly distribution payable to our common shareholders of record on July 27, 2020 in the amount of $0.01 per share, or approximately $2,380. We expect to pay this distribution on or about August 20, 2020.
Note 9. Segment Reporting
We operate in, and report financial information for, the following two segments: Office Portfolio and senior housing operating portfolio, or SHOP. We aggregate each of these two reporting segments based on their similar operating and economic characteristics. Our Office Portfolio segment consists of medical office properties leased to medical providers and other medical related businesses, as well as life science properties leased to biotech laboratories and other similar tenants. Our SHOP segment consists of managed senior living communities that provide short term and long term residential living and in some instances care and other services for residents where we pay fees to the operator to manage the communities for our account. In addition, prior to January 1, 2020, our SHOP segment included triple net leased senior living communities that provided short term and long term residential living and in some instances care and other services for residents and from which we received rents from Five Star. Pursuant to the Restructuring Transaction, effective January 1, 2020, our previously existing master leases and management and pooling agreements with Five Star were terminated and replaced with new management and related agreements, or collectively, the New Management Agreements, for all of our senior living communities operated by Five Star. Prior periods have been recast to reflect these reportable segments for all periods presented.
We also report “non-segment” operations, which consists of triple net leased senior living communities, which are leased to operators other than Five Star from which we receive rents, and wellness centers, which we do not consider to be sufficiently

Under the Coronavirus Aid, Relief, and Economic Security Act, or the CARES Act, the U.S. Department of Health and Human Services, or HHS, established the Provider Relief Fund. Retention and use of the funds received under the CARES Act are subject to certain terms and conditions. The terms and conditions require that the funds be utilized to compensate for lost revenues that are attributable to the COVID-19 pandemic and for eligible costs to prevent, prepare for and respond to the COVID-19 pandemic that are not covered by other sources. Further, fund recipients are required to be participating in Medicare at the time of distribution and are subject to certain other terms and conditions, including quarterly reporting requirements. In addition, fund recipients are required to have billed Medicare during 2019 and to continue to provide care after January 31, 2020 for diagnosis, testing or care for individuals with possible or actual COVID-19 cases. Any funds not used in accordance with the terms and conditions must be returned to HHS. As of June 30, 2020, we had received $10,133 in funds from the Provider Relief Fund to be used to support the operations of our managed senior living communities; we have currently determined that $7,346 of such funds meet the required terms and conditions and have therefore recognized such amount as other income with respect to our SHOP segment for the three and six months ended June 30, 2020. We currently expect to return the remaining $2,787 of such funds to HHS in August 2020 unless we determine that such funds meet the required terms and conditions and have therefore included that amount in other liabilities in our condensed consolidated financial statements as of June 30, 2020.

Note 10. Leases and Management Agreements with Five Star
As of December 31, 2019, we leased 166 senior living communities to Five Star. As of that date, we also leased to our taxable REIT subsidiaries, or TRSs, 78 communities that we owned and that were managed by Five Star for our account.
Restructuring of our Business Arrangements with Five Star
The Transaction Agreement with Five Star. Pursuant to the Transaction Agreement, effective January 1, 2020, or the Conversion Time:

• | our previously existing master leases with Five Star for all of our senior living communities that Five Star leased, as well as our previously existing management agreements and pooling agreements with Five Star for our senior living communities that Five Star managed, were terminated and replaced, or the Conversion, with the New Management Agreements;

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
(dollar amounts in thousands, except per share data or as otherwise stated)

• | Five Star issued to us 10,268,158 Five Star common shares and an aggregate of 16,118,849 Five Star common shares to our shareholders of record as of December 13, 2019; and

• | as consideration for these share issuances, we provided Five Star with $75,000 of additional consideration by assuming certain of Five Star's working capital liabilities and through cash payments, resulting in a gain on lease termination of $22,896 for the six months ended June 30, 2020 in our condensed consolidated statements of comprehensive income (loss).

Also pursuant to the Transaction Agreement: (1) commencing February 1, 2019, the aggregate amount of monthly minimum rent payable to us by Five Star under our previously existing master leases with Five Star was set at $11,000 as of February 1, 2019, subject to adjustment, and subsequently reduced in accordance with the Transaction Agreement as a result of our subsequent sales of certain of the leased senior living communities, and no additional rent was payable to us by Five Star from such date until the Conversion Time; and (2) as of April 1, 2019, we purchased from Five Star $49,155 of unencumbered Qualifying PP&E (as defined in the Transaction Agreement) related to our senior living communities leased and operated by Five Star.
Pursuant to the New Management Agreements, Five Star receives a management fee equal to 5% of the gross revenues realized at the applicable senior living communities plus reimbursement for its direct costs and expenses related to such communities, as well as an annual incentive fee equal to 15% of the amount by which the annual earnings before interest, taxes, depreciation and amortization, or EBITDA, of all communities on a combined basis exceeds the target EBITDA for all communities on a combined basis for such calendar year, provided that in no event shall the incentive fee be greater than 1.5% of the gross revenues realized at all communities on a combined basis for such calendar year.
The New Management Agreements expire in 2034, subject to Five Star's right to extend for two consecutive five year terms if Five Star achieves certain performance targets for the combined managed communities portfolio, unless earlier terminated. The New Management Agreements also provide us with the right to terminate the New Management Agreement for any community that does not earn 90% of the target EBITDA for such community for two consecutive calendar years or in any two of three consecutive calendar years, with the measurement period commencing January 1, 2021 (and the first termination not possible until the beginning of calendar year 2023), provided we may not in any calendar year terminate communities representing more than 20% of the combined revenues for all communities for the calendar year prior to such termination. Pursuant to a guaranty agreement dated as of January 1, 2020 made by Five Star in favor of our applicable subsidiaries, Five Star has guaranteed the payment and performance of each of its applicable subsidiary's obligations under the applicable New Management Agreements.
On April 1, 2019, we concluded that the Restructuring Transaction constituted a reconsideration event requiring us to assess whether we held a controlling financial interest in Five Star. As a result of this assessment, we determined that Five Star was a VIE effective as of the date of the Transaction Agreement. We determined not to consolidate Five Star in our condensed consolidated financial statements, as we do not have the power to direct the activities of Five Star that most significantly impact Five Star's economic performance and therefore are not the primary beneficiary of Five Star. Effective January 1, 2020, we determined that Five Star is not a VIE and we will account for our 33.9% investment in Five Star using the equity method of accounting because we are deemed to exert significant influence, but not control, over Five Star's most significant activities. We have elected to use the fair value option to account for our investment in Five Star.
Our Senior Living Communities Formerly Leased by Five Star. Prior to the Conversion Time, we leased senior living communities to Five Star pursuant to five master leases with Five Star, each of which was terminated as of January 1, 2020 pursuant to the Transaction Agreement.
Under our previously existing leases with Five Star, Five Star paid us annual rent plus percentage rent equal to 4.0% of the increase in gross revenues at certain of our senior living communities over base year gross revenues as specified in the applicable leases. We recognized rental income payable by Five Star of $33,400 and $72,713 (including percentage rent of $538 for each applicable period) for the three and six months ended June 30, 2019, respectively. Rental income from Five Star represented 12.7% and 13.8% of our total revenues for the three and six months ended June 30, 2019, respectively, and the properties Five Star leased from us represented 26.4%, excluding properties held for sale, of our real estate investments, at cost, as of June 30, 2019. Pursuant to the Transaction Agreement, commencing February 1, 2019, no percentage rent was payable to us by Five Star. We previously determined percentage rent due under these leases annually and recognized it when all contingencies were met, which was typically at year end.

Our previously existing leases with Five Star were “triple net” leases, which generally required Five Star to pay rent and all property operating expenses, to indemnify us from liability which may arise by reason of our ownership of the properties, to maintain the properties at Five Star's expense, to remove and dispose of hazardous substances on the properties in compliance with applicable law and to maintain insurance on the properties for Five Star's and our benefit.
For the six months ended June 30, 2019, we funded $86,288 of improvements to communities leased to Five Star, including $49,155 of fixed assets and improvements that we purchased pursuant to the Transaction Agreement as discussed above. Also pursuant to the Transaction Agreement, Five Star's rent did not increase as a result of these purchases.
Our Senior Living Communities Managed by Five Star. Five Star managed 241 and 77 senior living communities for our account as of June 30, 2020 and 2019, respectively. We lease our senior living communities that are managed by Five Star to our TRSs, and Five Star manages these communities pursuant to long term management agreements. As described above, pursuant to the Transaction Agreement, effective January 1, 2020, we replaced our long term management and pooling agreements with Five Star with the New Management Agreements, the terms of which are described above.
We incurred management fees payable to Five Star of $15,262 and $3,871 for the three months ended June 30, 2020 and 2019, respectively, and $31,850 and $7,660 for the six months ended June 30, 2020 and 2019, respectively. These amounts are included in property operating expenses or have been capitalized, as appropriate, in our condensed consolidated financial statements.

In addition to providing management services to us, Five Star also provides certain other services to residents at some of the senior living communities it manages for us, such as rehabilitation services. At senior living communities Five Star manages for us where Five Star provides rehabilitation services on an outpatient basis, the residents, third party payers or government programs pay Five Star for those rehabilitation services. At senior living communities Five Star manages for us where Five Star provides both inpatient and outpatient rehabilitation services, we generally pay Five Star for those rehabilitation services and charges for these services are included in amounts charged to residents, third party payers or government programs. We incurred fees of $5,814 and $1,513 for the three months ended June 30, 2020 and 2019, respectively, and $13,871 and $3,188 for the six months ended June 30, 2020 and 2019, respectively, with respect to rehabilitation services Five Star provided at senior living communities it manages for us that are payable by us. These amounts are included in property operating expenses in our condensed consolidated statements of comprehensive income (loss).
Since January 1, 2020, we sold certain senior living communities that were then managed by Five Star. We and Five Star terminated our management agreements for these senior living communities in connection with these sales. We have also identified additional senior living communities for sale that are currently managed by Five Star. If these sales are consummated, we and Five Star will terminate the management agreements for these senior living communities. See Note 3 for further information regarding these sales.
We lease to Five Star space at certain of our senior living communities that Five Star manages, which it uses to provide certain inpatient and outpatient rehabilitation and wellness services. We recognized rental income of $488 and $782 for the three and six months ended June 30, 2020, respectively, with respect to these leases.

AIC. Until its dissolution in February 2020, we, ABP Trust, Five Star and four other companies to which RMR LLC provides management services owned Affiliates Insurance Company, or AIC, an Indiana insurance company, in equal amounts.

We and the other AIC shareholders historically participated in a combined property insurance program arranged and insured or reinsured in part by AIC.

These amounts are included in other assets, net in our condensed consolidated balance sheets. In June 2020, we received an additional liquidating distribution of approximately $287 from AIC in connection with its dissolution. We did not recognize any income related to our investment in AIC for the three and six months ended June 30, 2020 and recognized $130 and $534 related to our investment in AIC for the three and six months ended June 30, 2019, respectively. These amounts are presented as equity in earnings of an investee in our condensed consolidated statements of comprehensive income (loss). Our other comprehensive income included our proportionate share of unrealized gains on securities that were owned by AIC, related to our investment in AIC.
For further information about these and other such relationships and certain other related person transactions, see our Annual Report.
Note 13. Income Taxes
We have elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended, and, as such, are generally not subject to federal and most state income taxation on our operating income provided we distribute our taxable income to our shareholders and meet certain organization and operating requirements. We do, however, lease our managed senior living communities to our wholly owned TRSs that, unlike most of our subsidiaries, file a separate consolidated federal corporate income tax return and are subject to federal and state income taxes. Our consolidated income tax provision includes the income tax provision related to the operations of our TRSs and certain state income taxes we incur despite our taxation as a REIT. During the three months ended June 30, 2020 and 2019, we recognized income tax expense of $1,126 and benefit of $35, respectively, and during the six months ended June 30, 2020 and 2019, we recognized income tax expense of $683 and $99, respectively.
Note 14. Weighted Average Common Shares
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, and the related

impact on earnings, are considered when calculating diluted earnings per share. For the three months ended June 30, 2020 and 2019, 346 and 68 unvested common shares, respectively, and for the six months ended June 30, 2020 and 2019, 234 and 18 unvested common shares, respectively, were not included in the calculation of diluted earnings per share because to do so would have been antidilutive.
Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion should be read in conjunction with our condensed consolidated financial statements and notes thereto included in this Quarterly Report on Form 10-Q and with our Annual Report.
Impact of COVID-19
In March 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic and, in response to the outbreak, the U.S. Health and Human Services Secretary declared a public health emergency in the United States and many states and municipalities declared public health emergencies. The virus that causes COVID-19 has continued to spread throughout the United States and the world. Various governmental and market responses attempting to contain and mitigate the spread of the virus have negatively impacted, and continue to negatively impact, the global economy, including the U.S. economy. As a result, most market observers believe the global economy and the U.S. economy are in a recession. States and municipalities across the United States have been allowing certain businesses to re-open and easing certain restrictions they had previously implemented in response to the COVID-19 pandemic, often in stages that are phased in over time. Recently, economic data have indicated that the U.S. economy has improved since the lowest periods experienced in March and April 2020. However, certain areas of the United States have experienced increased numbers of COVID-19 infections following the re-openings of their economies and easing of restrictions or otherwise and, in some cases, certain states have imposed or re-imposed closings of certain business activities and other restrictions in response. It is unclear whether the increases in the number of COVID-19 infections will continue or amplify or whether any “second wave” of COVID-19 infection outbreaks will occur in the United States or elsewhere and, if so, what the impact of that would be on human health and safety, the economy, our manager and tenants or our business.
Our business is focused on healthcare related properties, including medical office and life science properties, senior living communities, wellness centers and other medical and healthcare related properties. We believe that the healthcare sector and many of our tenants provide essential services across the United States. Due to restrictions intended to prevent the spread of the virus that causes COVID-19, certain of our medical office and wellness center tenants, which include physician practices that had discontinued non-essential surgeries and procedures and fitness centers, that had been ordered closed by state executive orders have experienced disruptions to their businesses. Our senior living operators have also experienced disruptions, including limitations on in-person tours and new admissions, and are experiencing challenges in attracting new residents to their communities in addition to experiencing increased expense levels due to increased labor costs and higher costs and consumption of supplies, including personal protective equipment. There will be lasting impacts of the COVID-19 pandemic, even as states and municipalities re-open their economies. Our tenants and their businesses may become increasingly negatively impacted, which may result in our tenants seeking assistance from us regarding their rent obligations owed to us, their being unable or unwilling to pay us rent, their ceasing to pay us rent and their ceasing to continue as going concerns. We expect that our senior living operators will be operating our communities at lower average occupancy with higher operating expenses, which will likely lead to decreased returns to us as a result of this pandemic. As of July 31, 2020, we have been notified that 4.5% of residents in our senior living communities have tested positive for COVID-19 since the pandemic began. Our operators continue to follow federal, state and local health department guidelines and their own infection prevention protocols but we expect to see additional cases of COVID-19 in our senior living communities.
We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business, including:

• | our tenants and their ability to withstand the current economic conditions and continue to pay us rent;

• | our senior living community operators' ability to operate our communities, mitigate and contain the spread of the virus that causes COVID-19 at our communities and to keep the residents and our operators' employees at our communities safe and healthy;

• | our operations, liquidity and capital needs and resources;

22

Table of Contents

• | conducting financial modeling and sensitivity analyses;

• | actively communicating with our tenants, our operators and other key constituents and stakeholders in order to help assess market conditions, opportunities, best practices and mitigate risks and potential adverse impacts; and

• | monitoring, with the assistance of counsel and other specialists, possible government relief funding sources and other programs that may be available to us, our tenants, or our operators to enable us and them to operate through the current economic conditions and enhance our tenants' ability to pay us rent or our operators' ability to operate our communities.

We believe that our current financial position and recent financing activities will enable us to withstand the COVID-19 pandemic and its aftermath due in part to the following:

• | On June 2, 2020, we issued $1.0 billion aggregate principal amount of our 9.75% senior notes due 2025. We used the net proceeds from this offering to prepay in full our $250.0 million unsecured term loan that was scheduled to mature on June 12, 2020 and to reduce amounts outstanding under our revolving credit facility;

• | Beginning in the second quarter of 2020, we reduced our quarterly cash distribution rate on our common shares to $0.01 per share, conserving approximately $33.3 million of cash per calendar quarter compared to our prior quarterly distribution rate;

• | As of August 3, 2020, we had $1.0 billion of availability under our revolving credit facility; and

• | Our next debt maturity does not occur until our $300.0 million senior unsecured notes mature in December 2021.

In light of the above actions, resources, expectations and conditions, we believe that we are well positioned to weather the present disruptions facing the real estate industry and, in particular, the real estate healthcare industry, including senior living. However, as a result of the COVID-19 pandemic, some of our tenants have requested relief from their obligations to pay rent due to us. While the number and value of these monthly requests have been declining, we continue to evaluate these requests as they are made on a tenant-by-tenant basis. As of August 3, 2020, we granted requests to 106 of our tenants to defer rent payments totaling $5.5 million with respect to leases that represent, as of June 30, 2020, approximately 9.4% of our annualized rental income. Those 106 of our tenants consist of 104 tenants in our Office Portfolio segment, one wellness center tenant and one triple net senior living tenant. As of June 30, 2020, we recognized an increase in our accounts receivable balance related to these deferred rent payments of $3.5 million. These tenants are obligated to pay, in most cases, the deferred rents in 12 equal monthly installments commencing in September 2020. For the three months ended June 30, 2020, we collected approximately 99% of our contractual rents due from tenants in our Office Portfolio segment. These deferred amounts did not negatively impact our results for the three and six months ended June 30, 2020. However, the deferred rents have temporarily reduced our operating cash flows.
We do not have any employees and the personnel and various services we require to operate our business are provided to us by RMR LLC pursuant to our business and property management agreements with RMR LLC for our Office Portfolio. RMR LLC has implemented enhanced cleaning protocols and social distancing guidelines at its corporate headquarters and regional offices, as well as business continuity plans to ensure that RMR LLC employees remain safe and able to support us and other companies managed by RMR LLC or its subsidiaries, including providing appropriate information technology such as notebook computers, smart phones, computer applications, information technology security applications and technology support.
With respect to our properties where property management is provided by RMR LLC, RMR LLC has implemented enhanced cleaning protocols and has taken measures to reduce the possibility of persons gathering in groups and in close proximity to each other, for the purpose of mitigating the potential for the spread of COVID-19 infections. Included among these protocols and measures are the following:

• | focusing on sanitizing high touch points in common areas and restrooms;

• | shutting down certain building amenities; and

• | prudently managing the execution or deferment of tenant work orders to limit RMR LLC staff and tenant interactions at our properties.

23

Table of Contents
All RMR LLC property management and engineering personnel have been trained on COVID-19 precaution procedures. As states and local communities across the country moved to stay at home orders, RMR LLC worked to reduce and optimize our operating costs at our properties by:

• | deferring non-emergency work;

• | implementing energy reduction protocols for lighting and HVAC systems;

• | reducing non-essential building services and staff; and

• | reducing the frequency of trash removal.

RMR LLC's property management teams have also established business continuity plans to ensure operational stability at our properties. As stay at home orders have been lifted or loosened across the United States, RMR LLC has implemented additional procedures at our properties that RMR LLC manages based on recommended guidelines from the U.S. Centers for Disease Control and Prevention and other regulatory agencies. For example:

• | installing signage throughout our managed properties with social distancing reminders;

• | making changes to certain building HVAC systems and equipment, including adjusting indoor air control programs to increase the amount of outside air delivered to interior spaces and to adjust control sequences to maintain relative humidity levels in order to help minimize the concentration of the virus that causes COVID-19;

• | flushing domestic water systems to prepare for re-occupancy;

• | performing service calls and preventative maintenance after business hours to limit social interactions;

• | requiring vendors to follow best practices under COVID-19 pandemic conditions, including providing RMR LLC with documented preventative measures for their employees and requiring that staff wear appropriate personal protective equipment when working at our properties; and

• | altering cleaning schedules to perform vacuuming at times intended to reduce the potential airborne spread of the virus.

RMR LLC has significantly reduced non-essential work travel and its regional leadership personnel have not been allowed to work in the same locations at the same time. RMR LLC also requires its employees who work at our properties to use personal protective equipment and business continuity bonus payments have been provided to certain essential workers at our properties. RMR LLC regional management offices are currently limiting walk-in visitors and maintain maximum office occupancy limits as required by state and local guidelines, including weekly rotations of employees as needed.
With respect to our SHOP segment, Five Star has taken a number of proactive measures to protect the health and safety of their staff and our residents and patients, including barring all nonessential visitors from our senior living communities and, in certain cases, limiting new resident admissions, enhancing their established flu and infectious disease prevention and control protocols and providing additional training for their staff in infectious disease prevention and control. Additionally, federal, state or local health departments may ban or limit admissions to our senior living communities as a precautionary measure.
We also believe that we, Five Star and our impacted tenants may benefit from provisions of the CARES Act, signed into law in March 2020, or other federal or state relief programs allowing them to continue or resume business activity. During the three and six months ended June 30, 2020, we recognized other income of $7.3 million related to funds received under the CARES Act.
There are extensive uncertainties surrounding the COVID-19 pandemic and its aftermath. These uncertainties include, among others:

• | the duration and severity of the negative economic impact;

• | the strength and sustainability of any economic recovery;

24

Table of Contents

• | the timing and process for how federal, state and local governments and other market participants may oversee and conduct the return of economic activity when the COVID-19 pandemic abates, such as what continuing restrictions and protective measures may remain in place or be added and what restrictions and protective measures may be lifted or reduced in order to foster a return of increased economic activity in the United States; and

• | whether, following a recommencing of more normal levels of economic activities, the United States or other countries experience any “second wave” of COVID-19 infection outbreaks and, if so, the responses of governments, businesses and the general public to those events.

As a result of these uncertainties, we are unable to determine what the ultimate impact will be on our, our tenants', our operators' and other stakeholders' businesses, operations, financial results and financial position. For further information and risks relating to the COVID-19 pandemic and its aftermath on us and our business, see Part II, Item 1A, “Risk Factors” of this Quarterly Report on Form 10-Q.
OVERVIEW
We are a REIT organized under Maryland law and own medical office and life science properties, senior living communities and other healthcare related properties throughout the United States. As of June 30, 2020, we owned 412 properties, including 21 properties classified as held for sale, located in 38 states and Washington, D.C., including one life science property owned in a joint venture arrangement in which we own a 55% equity interest. At June 30, 2020, the gross book value of our real estate assets at cost plus certain acquisition costs, before depreciation and purchase price allocations and less impairment write downs, was $8.3 billion, including $112.6 million of gross book value classified as held for sale in our condensed consolidated balance sheet. For the three months ended June 30, 2020, substantially all of our net operating income, or NOI, came from properties where a majority of the revenues are derived from our tenants' and residents' private resources.
RESTRUCTURING OF BUSINESS ARRANGEMENTS WITH FIVE STAR
As of December 31, 2019, Five Star operated 244 of our senior living communities in our SHOP segment, of which 166 communities were leased to Five Star and 78 communities were managed by Five Star for our account. Pursuant to the Restructuring Transaction, effective January 1, 2020, our previously existing master leases and management and pooling agreements with Five Star were terminated and replaced with the New Management Agreements for all of our senior living communities operated by Five Star. The Conversion was a significant change in our historical arrangements with Five Star and has resulted, and likely will continue to result in future periods, in our realizing significantly different operating results from our senior living communities, including increased variability. As of June 30, 2020, Five Star managed 241 senior living communities for our account.
For further information regarding the Restructuring Transaction, the Transaction Agreement and our other business arrangements with Five Star, see Notes 10 and 12 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Amounts include $112,631 of gross book value of 21 properties classified as held for sale as of June 30, 2020, which amounts are included in assets of properties held for sale in our condensed consolidated balance sheet.

(2) | Represents gross book value of real estate assets divided by number of rentable square feet or living units, as applicable, at June 30, 2020.

(3) | Includes $301 of revenues and $(573) of NOI from properties that we sold and $16,683 of revenues and $(1,062) of NOI from properties classified as held for sale in our condensed consolidated balance sheet as of June 30, 2020.

(4) | We calculate our NOI on a consolidated basis and by reportable segment. Our definition of NOI and our reconciliation of net income (loss) to NOI are included below under the heading “Non-GAAP Financial Measures.”

(5) | Our medical office and life science property leases include some triple net leases where, in addition to paying fixed rents, the tenants assume the obligation to operate and maintain the properties at their expense, and some net and modified gross leases where we are responsible for the operation and maintenance of the properties and we charge tenants for some or all of the property operating costs. A small percentage of our medical office and life science property leases are full-service leases where we receive fixed rent from our tenants and no reimbursement for our property operating costs.

(6) | Medical office and life science property occupancy data is as of June 30, 2020 and 2019 and includes (i) out of service assets undergoing redevelopment, (ii) space which is leased but is not occupied or is being offered for sublease by tenants and (iii) space being fitted out for occupancy.

(7) | Excludes data for periods prior to our ownership of certain properties, data for properties sold or classified as held for sale and data for which there was a transfer of operations during the periods presented.

(8) | Operating data for other triple net leased senior living communities leased to third party operators other than Five Star and wellness centers are presented based upon the operating results provided by our tenants for the 12 months ended March 31, 2020 and 2019, or the most recent prior period for which tenant operating results are made available to us. We have not independently verified tenant operating data.

Due to the COVID-19 pandemic, we anticipate that leasing activity may remain slow in our Office Portfolio and that we may continue to be prevented from, or impeded in, pursuing or accepting additional residents at our senior living communities due to restrictions intended to prevent the spread of the virus that causes COVID-19, including restricting nonessential visitors from some of our senior living communities. As a result, we expect to experience further decreases in occupancy at our senior living communities. Further, as noted above, we expect to continue to incur higher operating costs at our senior living communities as a result of the COVID-19 pandemic. These expected declines in occupancy and increases in operating costs at our senior living communities are expected to result in further decreases in income or returns from those properties.
During the three months ended June 30, 2020, we entered into lease renewals for 51,772 square feet and new leases for 7,550 square feet at our medical office and life science properties. The weighted average annual rental rate for leases entered during the quarter was $37.70 per square foot, which was 5.18% higher than the previous weighted average annual rental rate for the same space. Weighted (by annualized rental income) average lease term for leases entered during the second quarter of 2020 was 6.0 years. Commitments for tenant improvements, leasing commission costs and concessions for leases we entered during the second quarter of 2020 totaled $0.7 million, or $12.16 per square foot on average (approximately $2.02 per square foot per year of the lease term).

(1) | Annualized rental income is based on rents pursuant to existing leases as of June 30, 2020, including straight line rent adjustments, estimated recurring expense reimbursements for certain net and modified gross leases and excluding lease value amortization at certain of our medical office and life science properties. Annualized rental income also includes 100% of rental income as reported under GAAP from our life science property owned in a joint venture arrangement in which we own a 55% equity interest.

Lease expiration data for our other triple net leased senior living communities leased to third party operators and wellness centers has not been provided because there were no changes to the lease expiration schedules from those reported in our Annual Report. As a result of the COVID-19 pandemic's impact on operations at wellness centers, we are evaluating our options with respect to a tenant of six of our wellness centers. Annualized rental income from our leases with the tenant of these wellness centers totals approximately $7.9 million and, as of June 30, 2020, the applicable tenant was in default on its obligations to us under the applicable leases.
RESULTS OF OPERATIONS (dollars and square feet in thousands, unless otherwise noted)
We operate in, and report financial information for, the following two segments: Office Portfolio and SHOP. We aggregate each of these two reporting segments based on their similar operating and economic characteristics. Our Office Portfolio segment consists of medical office properties leased to medical providers and other medical related businesses, as well as life science properties leased to biotech laboratories and other similar tenants. Our SHOP segment consists of managed senior living communities that provide short term and long term residential living and in some instances care and other services for residents where we pay fees to the operator to manage the communities for our account. In addition, prior to January 1, 2020, our SHOP segment included triple net leased senior living communities that provided short term and long term residential living and in some instances care and other services for residents and from which we received rents from Five Star. Pursuant to the Restructuring Transaction, effective January 1, 2020, our previously existing master leases and management and pooling agreements with Five Star were terminated and replaced with the New Management Agreements for all of our senior living communities operated by Five Star. Prior periods have been recast to reflect these reportable segments for all periods presented.
We also report “non-segment” operations, which consists of triple net leased senior living communities that are leased to operators other than Five Star from which we receive rents and wellness centers, which we do not consider to be sufficiently material to constitute a separate reporting segment, and any other income or expenses that are not attributable to a specific reporting segment.

Rental income. Rental income decreased primarily due to our disposition of 24 properties since April 1, 2019 and a decrease in rental income at our comparable properties. Rental income decreased at our comparable properties primarily due to reduced parking revenue and occupancy at certain of our comparable properties related to the COVID-19 pandemic, partially offset by higher average rents achieved from our new and renewal leasing activity at certain of our comparable properties.
Property operating expenses. Property operating expenses consist of real estate taxes, utility expenses, insurance, management fees, salaries and benefit costs of property level personnel, repairs and maintenance expense, cleaning expense and other direct costs of operating these properties. The decrease in property operating expenses is primarily due to our disposition of 24 properties since April 1, 2019 and a decrease in property operating expenses at our comparable properties. Property operating expenses at our comparable properties decreased primarily due to decreases in utility expenses and other direct costs, partially offset by increases in real estate taxes and insurance expense at certain of our comparable properties.
Net operating income. The change in NOI reflects the net changes in rental income and property operating expenses described above.

(1) | Consists of senior living communities that we have owned and which have been operated by the same operator continuously since April 1, 2019; excludes communities classified as held for sale, if any.

Rental income. Rental income decreased due to the termination of our previously existing master leases with Five Star. Pursuant to the Restructuring Transaction, effective January 1, 2020, our previously existing master leases and management and pooling agreements with Five Star were terminated and replaced with the New Management Agreements for all of our senior living communities operated by Five Star. See Note 10 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for information regarding the Restructuring Transaction.
Residents fees and services. Residents fees and services are the revenues earned at our managed senior living communities. We recognize these revenues as services are provided and related fees are accrued. Residents fees and services increased primarily due to the Restructuring Transaction and the resulting change to our management arrangement with Five Star for all of our senior living communities that it operates and our acquisition of one active adult rental property since April 1, 2019, partially offset by decreases in occupancy and average monthly rates primarily due to the impact of the COVID-19 pandemic at both comparable and non-comparable properties for the three months ended June 30, 2020 compared to the three months ended June 30, 2019. We expect to experience continued downward pressure on our occupancy and average monthly rates as normal resident move-outs may not be replaced by new resident move-ins and potential residents may increasingly delay or forgo moving into senior living communities as a result of the COVID-19 pandemic.
Property operating expenses. Property operating expenses consist of real estate taxes, utility expenses, insurance, salaries and benefit costs of property level personnel, repairs and maintenance expense, management fees, cleaning expense and other direct costs of operating these communities. Property operating expenses increased primarily due to the Restructuring Transaction and the resulting change to our management arrangement with Five Star for all of our senior living communities that it operates, our acquisition of one active adult rental property since April 1, 2019 and increased costs associated with staffing and supplies due to the COVID-19 pandemic at both comparable and non-comparable properties for the three months ended June 30, 2020 compared to the three months ended June 30, 2019. As a result of the COVID-19 pandemic, we expect to continue experiencing higher operating expenses primarily driven by increased labor costs and increased cost and consumption of supplies, including personal protective equipment.
Net operating income. The change in NOI reflects the net changes in rental income, residents fees and services and property operating expenses described above.

(1) | Consists of properties that we have owned and which have been leased to the same operator continuously since April 1, 2019; excludes properties classified as held for sale, if any.

Rental income. Rental income decreased primarily due to the sale of 11 senior living communities leased to private operators since April 1, 2019 and a decrease in rental income at our comparable properties, partially offset by increased rents resulting from our purchase of improvements at our comparable properties since April 1, 2019. Rental income decreased at our comparable properties primarily due to a tenant default under leases for six of our wellness centers. As a result of the COVID-19 pandemic, many of our wellness centers have been ordered closed by state or local executive orders. In April 2020, we agreed to defer rent payments for four wellness centers in the second quarter of 2020 in exchange for the tenant agreeing to pay the deferred rents in 12 equal monthly installments beginning later in 2020. We continue to evaluate our options for our wellness centers operated by tenants in default of their lease obligations.
Net operating income. The change in NOI reflects the net changes in rental income described above.
Consolidated:
References to changes in the income and expense categories below relate to the comparison of consolidated results for the three months ended June 30, 2020, compared to the three months ended June 30, 2019.
Depreciation and amortization expense. Depreciation and amortization expense decreased primarily due to our disposition of 56 properties, certain depreciable leasing related assets becoming fully depreciated and certain of our acquired resident agreements becoming fully amortized since April 1, 2019, partially offset by our acquisition of an active adult rental property and the purchase of capital improvements at certain of our properties since April 1, 2019.
General and administrative expense. General and administrative expense consists of fees paid to RMR LLC under our business management agreement, legal and accounting fees, fees and expenses of our Trustees, equity compensation expense and other costs relating to our status as a publicly traded company. General and administrative expense decreased primarily due to a decrease in our business management fees expense as a result of lower trading prices for our common shares during the three months ended June 30, 2020 compared to the three months ended June 30, 2019.
Acquisition and certain other transaction related costs. Acquisition and certain other transaction related costs primarily represent costs incurred in connection with the Restructuring Transaction.
Impairment of assets. For further information about our asset impairment charges, see Note 3 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
(Loss) gain on sale of properties. (Loss) gain on sale of properties is the result of our sale of certain senior living communities and medical office properties during the three months ended June 30, 2020 and 2019. For further information regarding (loss) gain on sale of properties, see Note 3 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Dividend income. The decrease in dividend income is the result of our sale on July 1, 2019 of all of the RMR Inc. class A common stock that we owned.
31

Gains and losses on equity securities, net. Gains and losses on equity securities, net, represent the net unrealized gains and losses to adjust our investment in Five Star and former investment in RMR Inc. to their fair values.
Interest and other income. The increase in interest and other income is primarily due to $7,346 of funds we received from the U.S. Government pursuant to the CARES Act during the three months ended June 30, 2020.
Interest expense. Interest expense increased primarily due to an increase in average borrowings under our revolving credit facility and our issuance in June 2020 of $1,000,000 aggregate principal amount of our 9.75% senior notes due in 2025. These increases were partially offset by our redemption in May 2019 of all $400,000 of our 3.25% senior notes due 2019, our prepayment in December 2019 of our $350,000 term loan, a lower interest rate on our new $250,000 term loan we obtained in December 2019, which we subsequently repaid in June 2020, and decreases in LIBOR, resulting in a decrease in interest expense with respect to our floating rate debt.
Loss on early extinguishment of debt. We recorded a loss on early extinguishment of debt in connection with our prepayment of our $250,000 term loan and of a mortgage note during the three months ended June 30, 2020. We recorded a loss on early extinguishment of debt in connection with our prepayment of mortgage notes during the three months ended June 30, 2019.
Income tax (expense) benefit. Income tax (expense) benefit is the result of operating income we earned in certain jurisdictions where we are subject to state income taxes.
Equity in earnings of an investee. Equity in earnings of an investee represents our proportionate share of earnings from our investment in AIC. The decrease in equity in earnings of an investee is due to the dissolution of AIC in February 2020.

Rental income. Rental income decreased primarily due to our disposition of 26 properties since January 1, 2019, partially offset by an increase in rental income at our comparable properties. Rental income increased at our comparable properties primarily due to increases in tax escalation income and other expense reimbursement income and higher average rents achieved from our new and renewal leasing activity at certain of our comparable properties, partially offset by reduced parking revenue and occupancy related to the COVID-19 pandemic.
Property operating expenses. The decrease in property operating expenses is primarily due to our disposition of 26 properties since January 1, 2019, partially offset by increases in property operating expenses at our comparable properties. Property operating expenses at our comparable properties increased primarily due to increases in real estate taxes, insurance expense and other direct costs, partially offset by decreases in utility expenses at certain of our comparable properties.
Net operating income. The change in NOI reflects the net changes in rental income and property operating expenses described above.

Rental income. Rental income decreased due to the termination of our previously existing master leases with Five Star. Pursuant to the Restructuring Transaction, effective January 1, 2020, our previously existing master leases and management and pooling
34

agreements with Five Star were terminated and replaced with the New Management Agreements for all of our senior living communities operated by Five Star. See Note 10 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for information regarding the Restructuring Transaction.
Residents fees and services. Residents fees and services are the revenues earned at our managed senior living communities. We recognize these revenues as services are provided and related fees are accrued. Residents fees and services increased primarily due to the Restructuring Transaction and the resulting change to our management arrangement with Five Star for all of our senior living communities that it operates and our acquisition of one active adult rental property since January 1, 2019, partially offset by decreases in occupancy and average monthly rates primarily due to the impact of the COVID-19 pandemic at both comparable and non-comparable properties for the six months ended June 30, 2020 compared to the six months ended June 30, 2019. We expect to experience continued downward pressure on our occupancy and average monthly rates as normal resident move-outs may not be replaced by new resident move-ins and potential residents may increasingly delay or forgo moving into senior living communities as a result of the COVID-19 pandemic.
Property operating expenses. Property operating expenses increased primarily due to the Restructuring Transaction and the resulting change to our management arrangement with Five Star for all of our senior living communities that it operates, our acquisition of one active adult rental property since January 1, 2019 and increased costs associated with staffing and supplies due to the COVID-19 pandemic at both comparable and non-comparable properties for the six months ended June 30, 2020 compared to the six months ended June 30, 2019. As a result of the COVID-19 pandemic, we expect to continue experiencing higher operating expenses primarily driven by increased labor costs and increased cost and consumption of supplies, including personal protective equipment.
Net operating income. The change in NOI reflects the net changes in rental income, residents fees and services and property operating expenses described above.

Rental income. Rental income decreased primarily due to the sale of 11 senior living communities leased to private operators, the transfer of one senior living community we own from a triple net leased senior living community to a managed senior living community now included in our SHOP segment since January 1, 2019 and a decrease in rental income at our comparable properties, partially offset by increased rents resulting from our purchase of improvements at our comparable properties since January 1, 2019. Rental income decreased at our comparable properties primarily due to a tenant default under leases for six of our wellness centers. As a result of the COVID-19 pandemic, many of our wellness centers have been ordered closed by state or local executive orders. In April 2020, we agreed to defer rent payments for four wellness centers in the second quarter of 2020 in exchange for the tenant agreeing to pay the deferred rents in 12 equal monthly installments beginning later in 2020. We continue to evaluate our options for our wellness centers operated by tenants in default of their lease obligations.
Net operating income. The change in NOI reflects the net changes in rental income described above.
Consolidated:
References to changes in the income and expense categories below relate to the comparison of consolidated results for the six months ended June 30, 2020, compared to the six months ended June 30, 2019.
Depreciation and amortization expense. Depreciation and amortization expense decreased primarily due to our disposition of 58 properties, certain depreciable leasing related assets becoming fully depreciated and certain of our acquired resident agreements becoming fully amortized since January 1, 2019, partially offset by our acquisition of an active adult rental property and the purchase of capital improvements at certain of our properties since January 1, 2019.
General and administrative expense. General and administrative expense decreased primarily due to a decrease in our business management fees expense as a result of lower trading prices for our common shares during the six months ended June 30, 2020 compared to the six months ended June 30, 2019.
Acquisition and certain other transaction related costs. Acquisition and certain other transaction related costs primarily represent costs incurred in connection with the Restructuring Transaction.
Impairment of assets. For further information about our asset impairment charges, see Note 3 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Gain on sale of properties. Gain on sale of properties is the net result of our sale of certain senior living communities and office properties during the six months ended June 30, 2020 and 2019. For further information regarding gain on sale of properties, see Note 3 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Dividend income. The decrease in dividend income is the result of our sale on July 1, 2019 of all of the RMR Inc. class A common stock that we owned.
Gains and losses on equity securities, net. Gains and losses on equity securities, net, represent the net unrealized gains and losses to adjust our investment in Five Star and former investment in RMR Inc. to their fair values.
Interest and other income. The increase in interest and other income is primarily due to $7,346 of funds we received from the U.S. Government pursuant to the CARES Act during the six months ended June 30, 2020.
Interest expense. Interest expense decreased primarily due to our redemption in May 2019 of all $400,000 of our 3.25% senior notes due 2019, our prepayment in December 2019 of our $350,000 term loan, a lower interest rate on our new $250,000 term loan we obtained in December 2019, which we subsequently repaid in June 2020, and decreases in LIBOR, resulting in a decrease in interest expense with respect to our floating rate debt. These decreases were partially offset by an increase in average borrowings under our revolving credit facility and our issuance in June 2020 of $1,000,000 aggregate principal amount of our 9.75% senior notes due in 2025.
Gain on lease termination. Gain on lease termination represents the gain recognized in connection with the Restructuring Transaction. For information regarding the Restructuring Transaction, see Note 10 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
36

Loss on early extinguishment of debt. We recorded a loss on early extinguishment of debt in connection with our prepayment of our $250,000 term loan and mortgage notes during the six months ended June 30, 2020. We recorded a loss on early extinguishment of debt in connection with our prepayment of mortgage notes during the six months ended June 30, 2019.
Income tax expense. Income tax expense is the result of operating income we earned in certain jurisdictions where we are subject to state income taxes.
Equity in earnings of an investee. Equity in earnings of an investee represents our proportionate share of earnings from our investment in AIC. The decrease in equity in earnings of an investee is due to the dissolution of AIC in February 2020.
Non-GAAP Financial Measures (dollars in thousands, except per share amounts)
We present certain "non-GAAP financial measures" within the meaning of applicable rules of the Securities and Exchange Commission, or SEC, including funds from operations attributable to common shareholders, or FFO attributable to common shareholders, normalized funds from operations attributable to common shareholders, or Normalized FFO attributable to common shareholders, and NOI for the three and six months ended June 30, 2020 and 2019. These measures do not represent cash generated by operating activities in accordance with GAAP and should not be considered alternatives to net income (loss) or net income (loss) attributable to common shareholders as indicators of our operating performance or as measures of our liquidity. These measures should be considered in conjunction with net income (loss) and net income (loss) attributable to common shareholders 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) and net income (loss) attributable to common shareholders. We believe these measures provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation and amortization, 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.
Funds From Operations and Normalized Funds From Operations Attributable to Common Shareholders
We calculate FFO attributable to common shareholders and Normalized FFO attributable to common shareholders as shown below. FFO attributable to common shareholders is calculated on the basis defined by the National Association of Real Estate Investment Trusts, which is net income (loss) attributable to common shareholders, calculated in accordance with GAAP, excluding any gain or loss on sale of properties, loss on impairment of real estate assets and gains or losses on equity securities, net, if any, plus real estate depreciation and amortization and minus FFO adjustments attributable to noncontrolling interest, as well as certain other adjustments currently not applicable to us. In calculating Normalized FFO attributable to common shareholders, we adjust for the 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 attributable to common shareholders and Normalized FFO attributable to common shareholders 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 the agreements governing our debt, 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. O ther real estate companies and REITs may calculate FFO attributable to common shareholders and Normalized FFO attributable to common shareholders differently than we do.
Our calculations of FFO attributable to common shareholders and Normalized FFO attributable to common shareholders for the three and six months ended June 30, 2020 and 2019 and reconciliations of net income (loss) attributable to common shareholders, the most directly comparable financial measure under GAAP reported in our condensed consolidated financial statements, to FFO attributable to common shareholders and Normalized FFO attributable to common shareholders appear in the following table. This table also provides a comparison of distributions to shareholders, FFO attributable to common shareholders and Normalized FFO attributable to common shareholders and net income (loss) attributable to common shareholders per share for these periods.

Property Net Operating Income (NOI)
We calculate NOI as shown below. 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 define NOI as income from our 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. 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.

LIQUIDITY AND CAPITAL RESOURCES
Our principal sources of cash to meet operating and capital expenses, pay debt service obligations and make distributions to our shareholders are the operating cash flows we generate as rental income from our leased properties, residents fees and services revenues from our managed communities, borrowings under our revolving credit facility and proceeds from the disposition of certain properties. We believe that these sources 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 receive rents from our tenants in light of the COVID-19 pandemic and generally;

• | our ability to maintain or increase the occupancy of, and the rental rates at, our properties or reduce the extent of the declines in occupancy and rental rates in response to the COVID-19 pandemic, particularly at our senior living communities;

• | our ability to control operating expenses and capital expenses at our properties, including increased operating expenses in response to the COVID-19 pandemic; and

• | our manager's ability to operate our managed senior living communities during the COVID-19 pandemic and generally so as to maintain or increase our returns or, during the COVID-19 pandemic, to reduce the extent of the declines in our returns.

We continue to carefully monitor the developments of the COVID-19 pandemic and its impact on our tenants, operators and other stakeholders, including at our senior living communities.

In response to the operating challenges and uncertain economic challenges as a result of the COVID-19 pandemic, in June 2020, we issued $1.0 billion aggregate principal amount of our 9.75% senior notes due 2025. We used the net proceeds from this offering to prepay in full our $250.0 million unsecured term loan that was scheduled to mature on June 12, 2020 and to reduce amounts outstanding under our revolving credit facility. Additionally, beginning in the second quarter of 2020, we reduced our quarterly cash distribution rate on our common shares to $0.01 per share. As of August 3, 2020, we granted requests for certain of our tenants to defer rent payments totaling $5.5 million with respect to leases that represent, as of June 30, 2020, approximately 9.4% of our annualized rental income. These tenants are obligated to pay, in most cases, the deferred rents in 12 equal monthly installments commencing in September 2020. For the three months ended June 30, 2020, we collected approximately 99% of our contractual rents due from tenants in our Office Portfolio segment.
During the six months ended June 30, 2020, we sold 12 properties for an aggregate sales price of $68.2 million, excluding closing costs. In July and August 2020, we sold four properties for an aggregate sales price of $5.2 million, excluding closing costs, and as of August 3, 2020, we had 24 properties under agreements to sell for an aggregate sales price of approximately $231.7 million, excluding closing costs. The impact of the COVID-19 pandemic and the resulting economic conditions is likely to cause many of these property sales to be delayed or occur over a protracted period of time or not at all. The measures noted above and anticipated sales of our properties may not sufficiently offset the decrease in cash flows from operations and essential capital investments we make during the COVID-19 pandemic, which may negatively impact our liquidity and result in increased borrowings under our revolving credit facility.
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 (dollars in thousands):

|  | Six Months Ended June 30,
|  | 2020 |  | 2019
Cash and cash equivalents and restricted cash at beginning of period |  | $ | 52,224 |  |  | $ | 70,071 |
Net cash provided by (used in): |  |  |  |
Operating activities |  | 110,673 |  |  | 125,874 |
Investing activities |  | (7,397 | ) |  | (101,634 | )
Financing activities |  | (61,732 | ) |  | (33,145 | )
Cash and cash equivalents and restricted cash at end of period |  | $ | 93,768 |  |  | $ | 61,166 |

Our Operating Liquidity and Resources
We generally receive minimum rents from our tenants monthly or quarterly, we receive residents fees and services revenues, net of expenses, from our managed senior living communities monthly and we receive percentage rents from certain of our senior living community tenants monthly, quarterly or annually.
The decrease in cash provided by operating activities for the six months ended June 30, 2020 compared to the prior period was primarily due to the Restructuring Transaction and the results from the converted managed communities for the 2020 period being less than our rental income for these communities in the 2019 period, as well as reduced NOI as a result of dispositions of properties during 2019 and 2020 and resulting changes in our working capital assets and liabilities from the converted managed communities which are now included in our condensed consolidated balance sheets commencing in the 2020 period. Pursuant to the Restructuring Transaction, effective January 1, 2020, our previously existing master leases and management and pooling agreements with Five Star were terminated and replaced with the New Management Agreements for all of our senior living communities operated by Five Star, as described in Note 10 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. The decreases noted above are partially offset by a decrease in business management fee expenses in the 2020 period compared to the 2019 period, particularly as a result of no business management incentive fee expense having been paid in the 2020 period.
As noted elsewhere in this Quarterly Report on Form 10-Q, the COVID-19 pandemic has had a substantial adverse impact on the global economy. Depending on the duration and severity of this pandemic and the resulting economic downturn, our tenants' and operators' businesses may become significantly adversely impacted, which may result in their failing to pay rent to us or to renew their leases upon expiration, and we will realize decreased returns from our senior living communities. We have granted requests for certain of our tenants to defer rent payments totaling $5.5 million. These tenants are obligated to pay, in most cases, the deferred rents in 12 equal monthly installments commencing in September 2020. For the three months ended June 30, 2020, we collected approximately 99% of our contractual rents due from tenants in our Office Portfolio segment. As of June 30, 2020, we recognized an increase in our accounts receivable balance related to these deferred rent payments of $3.5 million. We are handling requests from our tenants for relief on an individual basis. We also believe that, other than in our SHOP segment, overall tenant retention levels may increase as a result of the COVID-19 pandemic.

Our Investing Liquidity and Resources
The decrease in cash used in investing activities for the six months ended June 30, 2020 compared to the prior year period was primarily due to higher proceeds from the sale of real estate properties in the 2020 period compared to the 2019 period.
The following is a summary of cash used for capital expenditures, development, redevelopment and other activities for the periods presented (dollars in thousands):

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

(1) | Office Portfolio segment lease related costs generally include capital expenditures to improve tenants' space or amounts paid directly to tenants to improve their space and other leasing related costs, such as brokerage commissions and tenant inducements.

(2) | Office Portfolio segment building improvements generally include expenditures to replace obsolete building components that extend the useful life of existing assets or other improvements to increase the marketability of the property.

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

(4) | Prior period includes capital improvements for communities that were previously leased to Five Star.

During the three and six months ended June 30, 2020, we invested $0.5 million and $0.8 million, respectively, in revenue producing capital improvements at certain of our triple net leased senior living communities leased to private operators, and, as a result, annual rents payable to us increased by approximately $0.02 million and $0.04 million, respectively, pursuant to the terms of the applicable leases. We used cash on hand and borrowings under our revolving credit facility to fund these purchases. These capital improvement amounts are not included in the table above.
During the three months ended June 30, 2020, commitments made for expenditures in connection with leasing space in our medical office and life science properties, such as tenant improvements and leasing costs, were as follows (dollars and square feet in thousands, except per square foot amounts):

|  | New Leases |  | Renewals |  | Total

We plan to continue investing essential capital in our senior living communities to better position these communities in their respective markets in order to increase our returns in future years but certain projects have been delayed and may continue
41

Table of Contents
to be delayed in the future due to COVID-19 related community access restrictions and other state and local ordinances that may limit our ability to proceed with these projects on a timely basis.
As of June 30, 2020, we have estimated unspent leasing related obligations at our triple net leased senior living communities and our medical office and life science properties of approximately $18.9 million.
We are currently in the process of redeveloping four properties in our Office Portfolio located in Tempe, AZ, San Diego, CA, Lexington, MA and Washington D.C. These redevelopment projects may require significant capital expenditures and time to complete. We have continued to progress on these redevelopments during 2020.
We expect disruptions to future disposition activity due to uncertain market conditions as a result of the COVID-19 pandemic and resulting economic conditions. For further information regarding our acquisitions and dispositions, see Note 3 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Pursuant to the Restructuring Transaction, on January 1, 2020, Five Star issued 10,268,158 Five Star common shares to us and an aggregate of 16,118,849 Five Star common shares to our shareholders of record as of December 13, 2019. In consideration of these share issuances, we provided Five Star with $75.0 million of additional consideration. For further information regarding the Restructuring Transaction, see Note 10 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Our Financing Liquidity and Resources
The increase in cash used in financing activities for the six months ended June 30, 2020 compared to the prior period was primarily due to our repayment in June 2020 of our $250.0 million senior unsecured term loan and increased repayments of borrowings under our revolving credit facility in the 2020 period compared to the 2019 period, partially offset by net proceeds from our issuance in June 2020 of $1.0 billion aggregate principal amount of our 9.75% senior notes and a reduction in distributions paid to our shareholders in the 2020 period.
As of June 30, 2020, we had $78.5 million of cash and cash equivalents and $1.0 billion available to borrow under our revolving credit facility. We typically use cash balances, borrowings under our revolving credit facility, net proceeds from offerings of debt or equity securities, net proceeds from the disposition of assets and the cash flows from our operations to fund our operations, debt repayments, distributions, property acquisitions, capital expenditures and other general business purposes.
In order to fund acquisitions and to meet cash needs that may result from timing differences between our receipt of rents and our desire or need to make distributions or pay operating or capital expenses, we maintain a $1.0 billion unsecured revolving credit facility. The maturity date of our revolving credit facility is January 15, 2022, and, subject to the payment of an extension fee and meeting other conditions, we have the option to extend the maturity date of the facility for an additional year. Our revolving credit facility provides that we can borrow, repay and re-borrow funds available under our revolving credit facility until maturity, and no principal repayment is due until maturity. The facility also includes a feature pursuant to which, following the termination of the Amendment Period, in certain circumstances maximum borrowings under the facility may be increased to up to $2.0 billion. At June 30, 2020, our revolving credit facility required interest to be paid on borrowings at the annual rate of 2.6%, plus a facility fee of 30 basis points per annum on the total amount of lending commitments under the facility. The interest rate premium and facility fee are each subject to adjustment based upon changes to our credit ratings. As of June 30, 2020 and August 3, 2020, we had no outstanding borrowings under our revolving credit facility.
In June 2020, we amended our credit and term loan agreements. The amendments modify certain of the financial covenants under these agreements through the Amendment Period, during which, subject to certain conditions, we will continue to have access to undrawn amounts under our revolving credit facility. We have the right to terminate the Amendment Period prior to June 30, 2021, subject to certain conditions. During the Amendment Period:

• | our interest rate premium over LIBOR under our revolving credit facility and term loan increased by 50 basis points;

• | we will generally be required to apply the net cash proceeds from the disposition of assets, capital markets transactions, debt financings or COVID-19 government stimulus programs, if allowed, to the repayment of outstanding loans under our revolving credit facility, if any;

• | we will be subject to certain additional covenants, including additional restrictions on our ability to incur indebtedness (with exceptions for borrowings under our revolving credit facility and certain other categories of secured and

42

Table of Contents
unsecured indebtedness), and to acquire real property or make other investments (with exceptions for, among other things, certain categories of capital expenditures and costs);

• | we will be required to maintain unrestricted liquidity (unrestricted cash and undrawn availability under our revolving credit facility) of not less than $200.0 million; and

• | our ability to pay distributions on our common shares will be limited to paying a cash dividend of $0.01 per common share per quarter and amounts required to maintain our qualification for taxation as a REIT and to avoid the payment of certain income and excise taxes.

When significant amounts are outstanding under our revolving credit facility, or as the maturities of our indebtedness approach, we intend to explore refinancing alternatives. Such alternatives may include incurring additional debt, selling certain properties and issuing new equity securities. In addition, we may also seek to participate in joint ventures or other arrangements that may provide us additional sources of financing. 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. We may also assume debt in connection with our acquisitions of properties or place new debt on properties we own.
We have a $200.0 million unsecured term loan that matures on September 28, 2022. This term loan includes a feature under which maximum borrowings may be increased to up to $400.0 million in certain circumstances. At June 30, 2020, this term loan required interest to be paid at the annual rate of 2.4%. The interest rate premium is subject to adjustment based upon changes to our credit ratings.
During the six months ended June 30, 2020, we paid quarterly cash distributions to our shareholders totaling approximately $38.1 million using existing cash balances and borrowings under our revolving credit facility. On July 16, 2020, we declared a quarterly distribution payable to common shareholders of record on July 27, 2020, of $0.01 per share, or approximately $2.4 million. We expect to pay this distribution on or about August 20, 2020 using cash on hand. For further information regarding the distribution we paid during 2020, see Note 8 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
We believe we will have access to various types of financings, including debt or equity offerings, to fund our future acquisitions and to pay our debts and other obligations as they become due. Our ability to complete, and the costs associated with, future debt transactions depends primarily upon credit market conditions and our then creditworthiness. We have no control over market conditions. Our credit and debt ratings, which were recently downgraded, depend upon evaluations by credit rating agencies of our business practices and plans, including our ability to maintain our earnings, to stagger our debt maturities and to balance our use of debt and equity capital so that our financial performance 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 activities in a manner which 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 that intention. As noted elsewhere in this Quarterly Report on Form 10-Q, it is uncertain what the duration and severity of the current economic downturn resulting from the COVID-19 pandemic will be. A protracted economic downturn may have various negative consequences including a decline in financing availability and increased costs for financing. Further, such conditions could also disrupt capital markets and limit our access to financing from public sources, particularly if the global financial markets experience significant disruptions.
In February 2020, we prepaid a mortgage note secured by one of our life science properties with an outstanding principal balance of approximately $1.6 million, a maturity date in March 2026 and an annual interest rate of 6.25%. We prepaid this mortgage using cash on hand and borrowings under our revolving credit facility.
In March 2020, our issuer credit rating was downgraded from BB+ to BB by S&P Global, or S&P, following our fourth quarter 2019 earnings release and the beginning of the awareness of the possible impact of the COVID-19 pandemic in the United States. Our unsecured debt rating was downgraded below BBB- by S&P and, as a result, the interest rate premiums under our revolving credit facility and then existing term loans increased effective April 1, 2020.
In April 2020, we redeemed all of our outstanding 6.75% senior notes due 2020 for a redemption price equal to the principal amount of $200.0 million plus accrued and unpaid interest of $6.75 million. We funded this redemption with cash on hand and borrowings under our revolving credit facility.
43

Table of Contents
In May 2020, Moody's Investors Service, or Moody's, downgraded our senior unsecured debt rating from Ba1 to Ba2. However, Moody's assigned a Ba1 rating to our recently issued 9.75% senior notes due 2025.
Also in May 2020, we prepaid a mortgage note secured by one of our medical office properties with an outstanding principal balance of approximately $1.2 million, a maturity date in January 2022 and an annual interest rate of 7.49%. We prepaid this mortgage using cash on hand and borrowings under our revolving credit facility.
In June 2020, we issued $1.0 billion aggregate principal amount of our 9.75% senior notes due 2025 in an underwritten public offering. These notes are guaranteed by all of our subsidiaries, except for certain excluded subsidiaries. We used the net proceeds from this offering to prepay in full our $250.0 million unsecured term loan that was scheduled to mature on June 12, 2020 and to reduce amounts outstanding under our revolving credit facility.
For further information regarding our outstanding debt, see Note 5 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Except for the limitations in the amendments to our credit and term loan agreements described above, our strategy related to property acquisitions and dispositions is materially unchanged from that disclosed in our Annual Report. Our plans for particular properties and other strategic considerations may cause us to change our acquisition and disposition strategies, and we may do so at any time and without shareholder approval. Further, such plans may continue to be impacted by the scope and duration of the COVID-19 pandemic.
Off Balance Sheet Arrangements
As of June 30, 2020, 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
Our principal debt obligations at June 30, 2020 were: (1) $2.7 billion outstanding principal amount of senior unsecured notes; (2) $200.0 million outstanding principal amount under our term loan; and (3) $685.4 million aggregate principal amount of mortgage notes (excluding premiums, discounts and net debt issuance costs) secured by seven properties. For further information regarding our indebtedness, see Note 5 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Our senior unsecured notes are governed by our senior unsecured notes indentures and their supplements. Our credit and term loan agreements 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 and term loan agreements, a change of control of us, as defined, which includes RMR LLC ceasing to act as our business and property manager. Our senior unsecured notes indentures and their supplements and our credit and term loan agreements also contain covenants that restrict our ability to incur debts, including debts secured by mortgages on our properties, in excess of calculated amounts and require us to maintain various financial ratios, and our credit and term loan agreements contain covenants that restrict our ability to make distributions to our shareholders in certain circumstances. As of June 30, 2020, we believe we were in compliance with all of the covenants under our senior unsecured notes indentures and their supplements, our credit and term loan agreements and our other debt obligations. Although we have taken steps to enhance our ability to maintain sufficient liquidity, as noted elsewhere in this Quarterly Report on Form 10-Q, a protracted negative economic impact resulting from the COVID-19 pandemic may cause increased pressure on our ability to satisfy financial and other covenants. If we believe we would not be able to satisfy our financial or other covenants, we would seek waivers or amendments prior to any covenant violation, which may lead to increased costs and interest rates, additional restrictive covenants or other lender protections. We can provide no assurance that we would be able to obtain these waivers or amendments or repay the related debt facilities, which would lead to an event of default or potential acceleration of amounts due on our outstanding debt.
Neither our senior unsecured notes indentures and their supplements, nor our credit and term loan agreements, contain provisions for acceleration which could be triggered by our debt ratings. However, under our credit and term loan agreements, our senior unsecured debt ratings are used to determine the fees and interest rates we pay. Accordingly, following our debt ratings downgrades, our interest expense and related costs under our credit and term loan agreements have increased. See "—Our Financing Liquidity and Resources" above for information regarding recent downgrades of our issuer credit rating and senior unsecured debt rating that resulted in a change in the interest rate premiums under our revolving credit facility and term loan.

Table of Contents
Our senior unsecured notes indentures and their supplements contain cross default provisions to any other debts of more than $20.0 million ($50.0 million or more in the case of our senior unsecured notes indentures and supplements entered in February 2016, February 2018 and June 2020). Similarly, our credit and term loan agreements have cross default provisions to other indebtedness that is recourse of $25.0 million or more and indebtedness that is non-recourse of $75.0 million or more.
The loan agreements governing the aggregate $620.0 million secured debt financing on the property owned by our joint venture contain customary covenants and provide for acceleration of payment of all amounts due thereunder upon the occurrence and continuation of certain events of default.
Supplemental Guarantor Information
In March 2020, the SEC released Release No. 33-10762, Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates Whose Securities Collateralize a Registrant's Securities, or Release 33-10762. Release 33-10762 amends the disclosure requirements related to certain registered securities under SEC Regulation S-X, Rules 3-10 and 3-16, permitting registrants to provide certain alternative financial disclosures and non-financial disclosures in lieu of separate consolidating financial statements for subsidiary issuers and guarantors of registered debt securities if certain conditions are met. The amendments in Release 33-10762 are generally effective for filings on or after January 4, 2021, with early adoption permitted. We adopted the new disclosure requirements permitted under Release 33-10762 effective for the period ended March 31, 2020.
All $1.0 billion of our 9.75% senior notes due 2025 are fully and unconditionally guaranteed, on a joint and several basis and on a senior unsecured basis, by all of our subsidiaries, except for certain excluded subsidiaries. The notes and the guarantees will be effectively subordinated to all of our and the subsidiary guarantors' secured indebtedness, respectively, to the extent of the value of the collateral securing such secured indebtedness, and will be structurally subordinated to all indebtedness and other liabilities and any preferred equity of any of our subsidiaries that do not guarantee the notes. Our remaining $1.85 billion of senior unsecured notes do not have the benefit of any guarantees.
A subsidiary guarantor's guarantee of our 9.75% senior notes due 2025 and all other obligations of such subsidiary guarantor under the indenture governing the notes will automatically terminate and such subsidiary guarantor will automatically be released from all of its obligations under such subsidiary guarantee and the indenture under certain circumstances, including on or after the date (a) the notes have an investment grade rating from two rating agencies and one of such investment grade ratings is a mid-BBB investment grade rating and (b) no default or event of default has occurred and is continuing under the indenture. Our non-guarantor subsidiaries are separate and distinct legal entities and will have no obligation, contingent or otherwise, to pay any amounts due on our 9.75% senior notes due 2025 or the guarantees, or to make any funds available therefor, whether by dividend, distribution, loan or other payments. The rights of holders of our 9.75% senior notes due 2025 to benefit from any of the assets of our non-guarantor subsidiaries are subject to the prior satisfaction of claims of those subsidiaries' creditors and any preferred equity holders. As a result, our 9.75% senior notes due 2025 and the guarantees will be structurally subordinated to all indebtedness, guarantees and other liabilities of our subsidiaries that do not guarantee our 9.75% senior notes due 2025, including guarantees of other indebtedness of ours, payment obligations under lease agreements, trade payables and preferred equity.

Related Person Transactions
We have relationships and historical and continuing transactions with RMR LLC, RMR Inc., Five Star and others related to them. For example: we have no employees and the personnel and various services we require to operate our business are provided to us by RMR LLC pursuant to our business and property management agreements with RMR LLC; RMR Inc. is the managing member of RMR LLC; Adam Portnoy, the Chair of our Board of Trustees and one of our Managing Trustees, is the sole trustee, an officer and the controlling shareholder of ABP Trust, which is the controlling shareholder of RMR Inc., and he is also a managing director and the president and chief executive officer of RMR Inc., an officer and employee of RMR LLC and the chair of the board of directors and a managing director of Five Star; Jennifer Clark, our other Managing Trustee and our Secretary, is a managing director and the executive vice president, general counsel and secretary of RMR Inc., an officer and employee of RMR LLC, an officer of ABP Trust and a managing director and the secretary of Five Star; and each of our officers is also an officer and employee of RMR LLC. We have relationships and historical and continuing transactions with other companies to which RMR LLC or its subsidiaries provide management services, and some of which have trustees, directors or officers who are also trustees, directors or officers of us, RMR LLC or RMR Inc. and some of our Trustees and officers serve as trustees, directors or officers of these companies. For example, Five Star is our former subsidiary and former largest tenant, and it currently manages most of our senior living communities and we and Five Star restructured our business arrangements as of January 1, 2020. We and Adam Portnoy, directly and indirectly through ABP Trust and its subsidiaries, are significant stockholders of Five Star, owning, as of June 30, 2020, 33.9% and 6.4%, respectively, of outstanding Five Star common shares.
For further information about these and other such relationships and related person transactions, see Notes 10, 11 and 12 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q, our Annual Report, our definitive Proxy Statement for our 2020 Annual Meeting of Shareholders and our other filings with the SEC. In addition, see the section captioned “Risk Factors” of our Annual Report and in this Quarterly Report on Form 10-Q for a description of risks that may arise as a result of these and other related person transactions and relationships.

Impact of Government Reimbursement
For the six months ended June 30, 2020, substantially all of our NOI was generated from properties where a majority of the revenues are derived from our tenants' and residents' private resources, and the remainder of our NOI was generated from properties where a majority of the revenues are derived from Medicare and Medicaid payments. Nonetheless, we own, and our tenants and manager operate, facilities in many states that participate in federal and state healthcare payment programs, including the federal Medicare and state Medicaid programs and other federal and state healthcare payment programs. Also, some of our medical office and life science property tenants participate in federal Medicare and state Medicaid programs and other government healthcare payment programs.
For more information regarding the government healthcare funding and regulation of our business, please see the section captioned “Business—Government Regulation and Reimbursement” in our Annual Report and the section captioned “Management's Discussion and Analysis of Financial Condition and Results of Operations—Impact of Government Reimbursement” in our Annual Report.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
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, 2019. 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.
Although we have no present plans to do so, we may in the future enter into hedge arrangements or derivative contracts from time to time to mitigate our exposure to changes in interest rates.
Fixed Rate Debt
At June 30, 2020, our outstanding fixed rate debt included the following (dollars in thousands):

|  |  |  | Annual |  | Annual |  |  |  |
|  | Principal |  | Interest |  | Interest |  |  |  | Interest
Debt |  | Balance (1) |  | Rate (1) |  | Expense |  | Maturity |  | Payments Due
Senior unsecured notes |  | $ | 300,000 |  |  | 6.75 | % |  | $ | 20,250 |  |  | 2021 |  | Semi-Annually
Senior unsecured notes |  | 250,000 |  |  | 4.75 | % |  | 11,875 |  |  | 2024 |  | Semi-Annually
Senior unsecured notes |  | 1,000,000 |  |  | 9.75 | % |  | 97,500 |  |  | 2025 |  | Semi-Annually
Senior unsecured notes |  | 500,000 |  |  | 4.75 | % |  | 23,750 |  |  | 2028 |  | Semi-Annually
Senior unsecured notes |  | 350,000 |  |  | 5.63 | % |  | 19,705 |  |  | 2042 |  | Quarterly
Senior unsecured notes |  | 250,000 |  |  | 6.25 | % |  | 15,625 |  |  | 2046 |  | Quarterly
Mortgage note |  | 12,181 |  |  | 6.28 | % |  | 765 |  |  | 2022 |  | Monthly
Mortgage note |  | 10,843 |  |  | 4.85 | % |  | 526 |  |  | 2022 |  | Monthly
Mortgage note |  | 15,970 |  |  | 5.75 | % |  | 918 |  |  | 2022 |  | Monthly
Mortgage note |  | 15,854 |  |  | 6.64 | % |  | 1,053 |  |  | 2023 |  | Monthly
Mortgage notes (2) |  | 620,000 |  |  | 3.53 | % |  | 21,886 |  |  | 2026 |  | Monthly
Mortgage note |  | 10,580 |  |  | 4.44 | % |  | 470 |  |  | 2043 |  | Monthly

(1) | The principal balances and 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 assumed certain of these debts. This table does not include obligations under finance leases.

(2) | The life science property encumbered by these mortgages is owned in a joint venture arrangement in which we own a 55% equity interest. The principal amounts listed in the table for these debts have not been adjusted to reflect the equity interest in the joint venture that we do not own.

No principal repayments are due under our unsecured notes until maturity. Our mortgage notes generally require principal and interest payments through maturity pursuant to amortization schedules. Because these debts require interest to be paid at a
47

Table of Contents
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 $33.4 million.
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, 2020, and discounted cash flows 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 $35.9 million.
Our senior unsecured notes and certain of our mortgages contain provisions that 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 noteholder. In the past, we have repurchased and retired some of our outstanding debts and we may do so again in the future. These prepayment rights and our ability to repurchase and retire outstanding debt may afford us opportunities to mitigate the risk of refinancing our debts at maturity at higher rates by refinancing prior to maturity.
Floating Rate Debt
At June 30, 2020, our floating rate debt obligations consisted of our $1.0 billion revolving credit facility, under which we had no outstanding borrowings, and our $200.0 million term loan. Our revolving credit facility matures in January 2022, and, subject to our payment of an extension fee and our meeting other conditions, we have the option to extend the stated maturity date by one year to January 2023. Generally, no principal repayments are required under our revolving credit facility prior to maturity, and we can borrow, repay and re-borrow funds available, subject to conditions, at any time without penalty. Our $200.0 million term loan matures in September 2022 and is prepayable without penalty at any time.
Borrowings under our revolving credit facility and term loan are in U.S. dollars and interest is required to be paid at the rate of LIBOR plus premiums that are subject to adjustment based upon changes to our credit ratings. Accordingly, we are exposed to interest rate risk for 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 or our term loan, 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, 2020 (dollars in thousands except per share amounts):

|  | Impact of Changes in Interest Rates
|  |  |  | Outstanding |  | Total Interest |  | Annual Earnings
|  | Interest Rate (1) |  | Floating Rate Debt |  | Expense Per Year |  | Per Share Impact (2)
At June 30, 2020 |  | 2.43 | % |  | $ | 200,000 |  |  | $ | 4,860 |  |  | $ | 0.02 |
One percentage point increase |  | 3.43 | % |  | $ | 200,000 |  |  | $ | 6,860 |  |  | $ | 0.03 |

(1) | Weighted based on the respective interest rates and outstanding borrowings under our credit facility and term loan as of June 30, 2020.

(2) | Based on weighted average number of shares outstanding (basic and diluted) for the six months ended June 30, 2020.

Table of Contents
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, 2020 if we were fully drawn on our revolving credit facility and our term loan remained outstanding (dollars in thousands except per share amounts):

|  | Impact of Changes in Interest Rates
|  |  |  | Outstanding |  | Total Interest |  | Annual Earnings
|  | Interest Rate (1) |  | Floating Rate Debt |  | Expense Per Year |  | Per Share Impact (2)
At June 30, 2020 |  | 2.53 | % |  | $ | 1,200,000 |  |  | $ | 30,360 |  |  | $ | 0.13 |
One percentage point increase |  | 3.53 | % |  | $ | 1,200,000 |  |  | $ | 42,360 |  |  | $ | 0.18 |

(1) | Weighted based on the respective interest rates and outstanding borrowings under our credit facility (assuming fully drawn) and term loan as of June 30, 2020.

(2) | Based on weighted average number of shares outstanding (basic and diluted) for the six months ended June 30, 2020.

The foregoing tables show the impact of an immediate increase in floating interest rates. 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 amount of our borrowings outstanding under our revolving credit facility or other floating rate debt.
LIBOR Phase Out
LIBOR is currently expected to be phased out in 2021. We are required to pay interest on borrowings under our revolving credit facility and term loan at floating rates based on LIBOR. 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 credit facility and term loan agreements would be revised as provided under the 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, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

• | Whether the aging U.S. population and increasing life spans of seniors will increase the demand for senior living communities and other medical and healthcare related properties and healthcare services,

• | Our ability to retain our existing tenants, attract new tenants and maintain or increase current rental rates on terms as favorable to us as our prior leases,

Table of Contents

• | 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 attributable to common shareholders, Normalized FFO attributable to common shareholders, NOI, cash flows, liquidity and prospects include, but are not limited to:

• | The impact of the COVID-19 pandemic and its aftermath on us and our tenants' and operators' businesses,

• | The impact of conditions in the economy and the capital markets on us and our tenants and operators,

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

• | 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,

• | Competition within the healthcare and real estate industries, particularly in those markets in which our properties are located,

• | Actual and potential conflicts of interest with our related parties, including our Managing Trustees, Five Star, RMR LLC, RMR Inc. and others affiliated with them, and

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

For example:

• | If the severity of the COVID-19 pandemic continues for an extended period or if business activity and the economy fail to sufficiently improve if and when the substantial adverse impacts of the COVID-19 pandemic abate, we may realize sustained losses and liquidity challenges. Further, we may incur increased operating expenses, particularly at our senior living communities, for supplies and personnel to address the current COVID-19 pandemic and we may be prevented from accepting additional residents at certain of our senior living communities if we become restricted from doing so due to the COVID-19 pandemic. In addition, under the current economic conditions, our tenants and operators may not be able to profitably operate their businesses at our properties, our tenants may become unable or unwilling to pay rent owed to us, or the manager of our senior living communities may be unable to generate our minimum returns for sustained periods. Additionally, our ability to borrow under our credit facility is subject to us satisfying financial and other covenants, and if we default under our credit facility or other debt obligations due to the impact of the COVID-19 pandemic or otherwise, we may be required to repay our outstanding borrowings and other debt. Further, although we have taken steps to enhance our ability to maintain sufficient liquidity, unanticipated events, such as emergencies in addition to, or as an expansion of, the current impact of the COVID-19 pandemic, may require us to expend amounts not currently planned,

• | The Conversion was a significant change in our business arrangements with Five Star and has resulted, and will likely continue to result in the future, in our realizing significantly different operating results from our senior living communities managed by Five Star, including increased variability in such results,

• | If Five Star fails to provide quality services at our senior living communities, the NOI generated by these communities may be adversely affected,

• | Five Star, the manager of our managed senior living communities, has experienced significant operating and financial challenges, resulting from a number of factors, some of which are beyond Five Star's control, and which challenges directly impact our operating results from our managed senior living communities, including, but not limited to:

• | The impact of the COVID-19 pandemic,

• | Increases in Five Star's labor costs or in costs Five Star pays for goods and services,

51

Table of Contents

• | Competition within the senior living industry,

• | Seniors delaying or forgoing moving into senior living communities or purchasing healthcare services that Five Star provides,

• | The impact of changes in the economy and the capital markets on Five Star and its residents and other customers,

• | Changes in Medicare or Medicaid policies and regulations or the possible future repeal, replacement or modification of these or other existing or proposed legislation or regulations,

• | Increases in compliance costs,

• | Continued efforts by third party payers to reduce healthcare costs,

• | Increases in tort and insurance liability costs, and

• | Five Star's exposure to litigation and regulatory and government proceedings due to the nature of its business.

• | If Five Star's other operations are not profitable or if it does not operate our managed senior living communities successfully, it could become insolvent,

• | We own a significant number of Five Star common shares and we expect to own these shares for the foreseeable future. However, we may sell some or all of our Five Star common shares, or our ownership interest in Five Star may otherwise be diluted in the future,

• | Beginning in the second quarter of 2020, we reduced our quarterly cash distribution rate on our common shares to $0.01 per share ($0.04 per common share annually) due to the operating challenges and uncertain economic challenges as a result of the COVID-19 pandemic. Our distribution rate may be set and reset from time to time by our Board of Trustees. Our Board of Trustees will consider many factors when setting or resetting our distribution rate, including our historical and projected net income, Normalized FFO, our then current and expected needs and availability of cash to pay our obligations, distributions which we may be required to pay to maintain our qualification for taxation as a REIT, limitations in the agreements governing our debt and other factors deemed relevant by our Board of Trustees in its discretion. Further, our projected cash available for distribution may change and may vary from our expectations. Accordingly, future distributions to our shareholders may be increased or decreased and we cannot be sure as to the rate at which future distributions will be paid,

• | 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 future earnings, the capital costs we incur to lease and operate 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,

• | We plan to selectively sell certain properties from time to time to fund future acquisitions, subject to limitations on acquisitions in agreements governing our debt, and to strategically update, rebalance and reposition our investment portfolio, which we refer to as our capital recycling program. In addition, to reduce our leverage, we have sold properties and other assets and have identified additional properties to sell. We expect that the pace of our future asset sales will slow considerably because of current market conditions related to the COVID-19 pandemic. We cannot be sure we will sell any of these properties or what the terms or timing of any such sales may be. In addition, in the case of our capital recycling program, we cannot be sure that we will acquire replacement properties that improve the quality of our portfolio or our ability to increase our distributions to shareholders, and, we may sell properties at prices that are less than expected and less than their carrying values and therefore incur losses,

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

• | The essential capital investments we are making at our senior living communities and our plan to invest additional capital into our senior living communities to better position them in their respective markets in order to increase our future returns may not be successful and may not achieve our expected results. Our senior living communities may not

52

Table of Contents
be competitive, despite these capital investments, or these capital investments may be delayed due to the COVID-19 pandemic,

• | Our redevelopment projects may not be successful and may cost more or take longer to complete than we currently expect. In addition, we may not realize the returns we expect from these projects and we may incur losses from these projects,

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

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

• | Our tenants may experience losses and default on their rent obligations to us,

• | Some of our tenants may not renew expiring leases, and we may be unable to obtain new tenants to maintain or increase the historical occupancy rates of, or rents from, our properties,

• | Our ability to grow our business and maintain or increase our distributions to shareholders depends in large part upon our ability to buy properties and arrange for their profitable operation or lease them for rents, less their property operating expenses, that exceed our capital costs. We may be unable to identify properties that we want to acquire, and are currently subject to limitations from making acquisitions under the agreements governing our debt, and we may fail to reach agreement with the sellers and complete the purchase of any properties we do want to acquire. In addition, any properties we may acquire may not provide us with rents or revenues less property operating costs that exceed our capital costs or achieve our expected returns. If our cash flows are reduced and our leverage increases, we may need to sell additional properties,

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

• | We expect to enter into additional management arrangements with Five Star for additional senior living communities that we own or may acquire in the future. However, we cannot be sure that we will enter into any additional management or other arrangements with Five Star,

• | 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 or other floating rate debt will be higher than LIBOR plus a premium because of fees and expenses associated with such debt,

• | The maximum borrowing availability under our revolving credit facility and our $200.0 million term loan may be increased to up to $2.4 billion on a combined basis in certain circumstances. However, increasing the maximum borrowing availability under our revolving credit facility and this term loan 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,

• | The premiums used to determine the interest rate payable on our revolving credit facility and term loan and the facility fee payable on our revolving credit facility are based on our credit ratings. In March 2020, our issuer credit rating was downgraded as a result of which our revolving credit facility and term loan premiums and facility fee increased,

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

• | 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,

• | For the three months ended June 30, 2020, substantially all of our NOI was generated from properties where a majority of the revenues are derived from our tenants' and residents' private resources. This may imply that we will maintain or increase the percentage of our NOI generated from private resources at our senior living communities.

53

Table of Contents
However, our residents and patients may become unable to fund our charges with private resources and we may be required or may elect for business reasons to accept or pursue revenues from government sources, which could result in an increased part of our NOI and revenue being generated from government payments and our becoming more dependent on government payments,

• | Circumstances that adversely affect the ability of seniors or their families to pay for our manager's and other operators' services, such as economic downturns, weak housing market conditions, higher levels of unemployment among our residents' family members, lower levels of consumer confidence, stock market volatility and/or changes in demographics generally could affect the profitability of our senior living communities,

• | It is difficult to accurately estimate tenant space preparation costs. Our unspent leasing related obligations may cost more or less and may take longer to complete than we currently expect, and we may incur increasing amounts for these and similar purposes in the future,

• | Our senior living communities are subject to extensive government regulation, licensure and oversight. We sometimes experience deficiencies in the operation of our senior living communities and some of our communities may be prohibited from admitting new residents or our license to continue operations at a community may be revoked. Also, operating deficiencies or a license revocation at one or more of our senior living communities may have an adverse impact on our ability to obtain licenses for or attract residents to our other communities,

• | We believe that our relationships with our related parties, including Five Star, RMR LLC, RMR Inc., ABP Trust 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

• | 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.

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, new legislation or regulations affecting our business or the businesses of our tenants or operators, changes in our tenants' or operators' revenues or costs, worsening or lack of improvement of Five Star's financial condition or changes in our other tenants' financial conditions, deficiencies in operations by a tenant or manager of one or more of our senior living communities, changed Medicare or Medicaid rates, acts of terrorism, pandemics, natural disasters or changes in capital markets or the economy generally.

PART II. Other Information
Item 1A. Risk Factors.
Our business faces many risks, a number of which are described under the caption “Risk Factors” in our Annual Report. The COVID-19 pandemic may subject us to additional risks that are described below. The risks described in our Annual Report and below may not be the only risks we face. Other risks of which we are not yet aware, or that we currently believe are not material, may also materially and adversely impact our business operations or financial results. If any of the events or circumstances described in the risk factors contained in our Annual Report or described below occurs, our business, financial condition or results of operations could be adversely impacted and the value of an investment in our securities could decline. Investors and prospective investors should consider the risks described in our Annual Report and below, and the information contained under the caption “Warning Concerning Forward-Looking Statements” and elsewhere in this Quarterly Report on Form 10-Q before deciding whether to invest in our securities.
Our business, operations, financial results and liquidity have been materially and adversely impacted by the COVID-19 pandemic, and it is not known what the duration of this pandemic will be or what its ultimate adverse impact on us and our business will be, but we expect it will be substantial.
COVID-19 has been declared a pandemic by the World Health Organization, and in response to the outbreak, the U.S. Health and Human Services Secretary has declared a public health emergency in the United States. The COVID-19 pandemic has had a substantial adverse impact on the global economy, including the U.S. economy, and has resulted in a global economic recession. These conditions have materially and adversely impacted our and many of our tenants' and our senior living communities' manager's businesses, results of operations and liquidity.
Our senior living communities have experienced increased operating costs. These increased costs result from staffing, including overtime, particularly if a community experiences a reduction in available personnel due to illness or otherwise, the increased need and cost for supplies, including personal protective equipment, adopting enhanced disinfection measures and/or implementing quarantines for residents. In addition, our senior living communities are experiencing downward pressures on occupancy as a result of restrictions on allowing outside persons to enter senior living communities due to social distancing and other containment measures, limitations on prospective residents being able to visit our senior living communities and perceptions that senior living communities are unsafe during a pandemic or other widespread illness. The occupancy at our senior living communities has declined since the start of the pandemic and we expect occupancy to continue to decline as a result of the pandemic and economic downturn, and the costs for operating those senior living communities have increased and we expect they may continue to increase during the COVID-19 pandemic and its aftermath, and these declines in occupancy and increases in operating costs may be significant. Those conditions would reduce the returns we realize from our senior living communities and the fees earned by the manager of our senior living communities, and these conditions may result in residents at our senior living communities being unable or unwilling to pay us rent and resident fees. Further, our manager and tenants may be limited in operating our senior living communities if they are unable to obtain the necessary staffing and supplies, such as a result of illness of staff, shortages of supplies due to supply chain or production challenges, or for other reasons. Additionally, downturns or stagnation in the U.S. housing market as a result of an economic downturn could adversely affect the ability, or perceived ability, of seniors to afford the resident fees and services at our senior living communities as prospective residents may use the proceeds from the sale of their homes to cover the cost of such fees.
In addition, economic downturns and recessions in the United States have historically negatively impacted the commercial office real estate market, including increased tenant defaults, decreased occupancies and reduced rental rates. The current economic conditions have had, and we expect that they will continue to have, similar negative impacts on our Office Portfolio and we expect that the extent of those negative consequences will depend to a large extent on the duration and depth of the economic recession in the United States and the strength and sustainability of any economic recovery that may follow.
We cannot predict the extent and duration of the COVID-19 pandemic or the severity and duration of its economic impact, but we expect it will be substantial.
Further, the extent and strength of any economic recovery after the COVID-19 pandemic abates, including following any "second wave" or other intensifying of the pandemic, are uncertain and subject to various factors and conditions. Our, the manager of our senior living communities and our tenants' businesses, operations and financial positions may continue to be negatively impacted after the COVID-19 pandemic abates and may remain at depressed levels compared to prior to the outbreak of the COVID-19 pandemic and those conditions may continue for an extended period.

Table of Contents
We have taken several actions in an attempt to address the operating and financial impact from the COVID-19 pandemic, and we continue to assess and explore other actions, but those actions and plans may not be sufficient to avoid continued and potentially increased substantial harm to our business, operations and financial condition.
We have taken several actions in an attempt to address the operating and financial impact from the COVID-19 pandemic, including:

• | we reduced our quarterly cash distribution rate on our common shares to $0.01 per share payable;

• | we amended certain financial covenants under our credit and term loan agreements through June 30, 2021 in order to provide us with additional flexibility;

• | we have been in regular, frequent contact with our senior living communities' manager to adopt measures to minimize losses, preserve liquidity and maintain operations; and

• | we have communicated with many of our medical office, life science and other tenants regarding their operation of or at our properties in the current challenging economic conditions, and we have agreed to provide deferrals of approximately $5.5 million of rent owed to us that are generally required to be repaid in installments beginning later this year.

There can be no assurance that these actions or others that we may take will be successful or that they will enable us to maintain sufficient liquidity and withstand the current economic challenges.
We recently reduced our quarterly cash distribution rate on our common shares to $0.01 per share; future distributions may remain at this level for an indefinite period or be eliminated and the form of payment could change.
Beginning in the second quarter of 2020, we reduced our quarterly cash distributions on our common shares to $0.01 per share. We currently intend to continue to make quarterly distributions to our shareholders at this rate for at least the Amendment Period, subject to applicable REIT tax requirements. However:

• | our ability to make or sustain the rate of distributions may continue to be adversely affected by the negative impact of the COVID-19 pandemic and its aftermath on our business, results of operations and liquidity;

• | our making of distributions is subject to restrictions contained in our credit and term loan agreements, including being limited to amounts required to maintain our qualification for taxation as a REIT and $0.01 per common share per quarter during the Amendment Period, and may be subject to restrictions in future debt obligations we may incur; during the continuance of any event of default under our credit and term loan agreements, we may be limited or in some cases prohibited from making distributions to our shareholders; and

• | the timing and amount of any distributions will be determined at the discretion of our Board of Trustees and will depend on various factors that our Board of Trustees deems relevant, including our historical and projected net income, Normalized FFO, our then current and expected needs and availability of cash to pay our obligations, distributions which we may be required to pay to maintain our qualification for taxation as a REIT, limitations in the agreements governing our debt and other factors deemed relevant by our Board of Trustees in its discretion.

For these reasons, among others, our distribution rate may not increase for an indefinite period and could be eliminated.
In order to preserve liquidity, we may elect to pay distributions to our shareholders, in part, in a form other than cash, such as issuing additional common shares of ours to our shareholders, as permitted by the applicable tax rules.
Our investment activities, other than maintenance and any urgent capital expenditures at our existing properties, have been significantly curtailed and we expect that to continue for an indefinite period.
We are not actively pursuing acquisitions at this time. In addition, we have reduced our expectations for capital spending significantly. In addition, our credit and term loan agreements limit our ability to make acquisitions and capital expenditures. As a result, we will be limited in pursuing investments, which may limit our ability to grow and to act upon opportunities we believe would benefit us. Further, to the extent we defer capital expenditures, we may be required to make increased capital expenditures in later periods as a result and some of the expenditures may be greater in scope and amount than they may have been if made sooner.

We expect that the sale of assets that we previously announced an intention to sell will be delayed and could be changed or abandoned.
We expect that the sales of some of our assets that we had previously identified for sale will be delayed until 2021 as a result of current market conditions. However, any sales of these assets may be delayed beyond our current expectations, they may not occur or, if they do occur, they may be sold at prices less than previously expected and we may realize losses from those assets. Our ability to sell these assets, and the prices we receive upon a sale, may continue to be affected by the impact of the COVID-19 pandemic, and we may be unable to execute our strategy.
Some of our tenants have requested relief from their obligations to pay rent due to us as a result of market disruptions due to the COVID-19 pandemic and we expect to receive additional similar requests in the future; we have provided certain limited relief in response to these requests and may determine to grant additional relief in the future if we determine it prudent or appropriate to do so.
The current economic conditions resulting from the COVID-19 pandemic have negatively impacted our tenants' businesses, operations and liquidity. As a result of market disruptions due to the COVID-19 pandemic, some of our tenants have requested relief from their obligations to pay rent due to us. As of August 3, 2020, we granted requests for certain of our tenants to defer rent payments totaling $5.5 million. These tenants are obligated to pay, in most cases, the deferred rents in 12 equal monthly installments commencing in September 2020. We expect to receive additional similar requests in the future, and we may determine to grant additional relief in the future, which may vary from the type of relief we have granted to date, and could include more substantial relief, if we determine it prudent or appropriate to do so. If conditions do not sufficiently and sustainably improve for these tenants, they may be unable to pay deferred or future rent owed to us when due or otherwise. In addition, if our tenants and senior living communities' manager are unable to continue as going concerns as a result of the current economic conditions or otherwise, we will experience a reduction in rents and returns received and we may be unable to find suitable replacement tenants and managers for an extended period or at all and the terms of our agreements with those replacement tenants and managers may not be as favorable to us as the terms of our agreements with our existing tenants and manager.
We may need waivers or amendments from our lenders in order to avoid defaulting under our revolving credit facility.
We may need to obtain waivers or amendments from our lenders under our revolving credit facility in the future in order to avoid failing to satisfy certain financial covenants under our credit and term loan agreements, but our lenders are not required to grant any such waivers and may determine not to do so. If we fail to receive any required waiver, we may default under our credit and term loan agreements and the lenders could terminate the credit facility and require us to pay our then outstanding borrowings under our credit facility. Any future waiver we may obtain may impose restrictions, which may limit our ability to pay distributions to our shareholders, make investments that we believe we should make and could reduce our ability to pursue business opportunities, grow our business and improve our operating results.
We do not expect to reduce our debt leverage in accordance with the timing contemplated by our previous plans and our debt leverage may remain at or above current levels for an indefinite period.
We previously announced an intention to reduce our debt leverage from proceeds from the planned sales of certain of our assets. As noted elsewhere in this Quarterly Report on Form 10-Q, we expect that the sale of some of these assets will be delayed, they may not occur and, if they do occur, they may be sold at prices less than previously expected. We expect the delay in these sales will also delay our ability to reduce our debt leverage. Further, if we realize a lower amount of proceeds from any asset sales than we previously expected, any corresponding reduction in our debt leverage would be similarly reduced. In addition, we may elect to incur additional debt in order to try to ensure that we have sufficient liquidity to manage through the current economic conditions and any extended economic downturn or recession that may result.
The COVID-19 pandemic may have significant impacts on workplace practices and those changes could be detrimental to our business.
Temporary closures of businesses and stay in place orders and the resulting remote working arrangements for nonessential personnel in response to the COVID-19 pandemic may result in long-term changed work practices that could negatively impact us and our business. For example, the increased adoption of and familiarity with remote work practices could result in decreased demand for office space, which could materially adversely impact our Office Portfolio and the values of our office properties. In addition, certain of our tenants' businesses depend on people gathering in close proximity, including fitness centers, among others. To the extent that social distancing practices that have been adopted in response to the COVID-19

pandemic become sustained practices, those tenants' businesses may be materially adversely impacted, which will reduce their ability to pay us rent, increase the likelihood they will default in paying us rent and likely reduce the value of those properties.
The high levels of infected COVID-19 patients and deaths at senior living communities and resulting negative publicity may have a long term significant detrimental impact on the senior living industry, including us, even if our senior living communities do not experience similar levels of COVID-19 infections and deaths as others in the industry.
COVID-19 has proven to be particularly harmful to seniors and persons with other pre-existing health conditions. If the senior living industry continues to experience high levels of residents infected with COVID-19 and related deaths, and news accounts emphasize these experiences, seniors may increasingly delay or forgo moving into senior living communities or using other services provided by senior living operators. These trends could be realized across the senior living industry and not discriminate among owners and operators that have higher or lower levels of residents experiencing COVID-19 infections and related deaths. As a result, our operating results from our senior living communities, and the values of those communities, may experience a long term significant detrimental impact.
