EQUITY COMMONWEALTH

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1.  Business

Equity Commonwealth, or the Company, is a real estate investment trust, or REIT, formed in 1986 under the laws of the State of Maryland. Our business is primarily the ownership and operation of office properties in the United States.

On November 10, 2016, the Company converted to what is commonly referred to as an umbrella partnership real estate investment trust, or UPREIT. In connection with this conversion, the Company contributed substantially all of its assets to EQC Operating Trust, a Maryland real estate investment trust, or the Operating Trust, and the Operating Trust assumed substantially all of the Company’s liabilities pursuant to a contribution and assignment agreement between the Company and the Operating Trust.

The Company now conducts and intends to continue to conduct substantially all of its activities through the Operating Trust. The Company beneficially owned 99.96% of the outstanding shares of beneficial interest, designated as units, in the Operating Trust, or OP Units, as of September 30, 2019, and the Company is the sole trustee of the Operating Trust.  As the sole trustee, the Company generally has the power under the declaration of trust of the Operating Trust to manage and conduct the business of the Operating Trust, subject to certain limited approval and voting rights of other holders of OP Units.

At September 30, 2019, our portfolio consisted of 7 properties (12 buildings), with a combined 2.5 million square feet. As of September 30, 2019, we had $3.2 billion of cash and cash equivalents.

Note 2.  Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements of EQC have been prepared without audit.  Certain information and footnote 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 appropriate.  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, or our Annual Report, for the year ended December 31, 2018.  Capitalized terms used, but not defined in this Quarterly Report, have the same meanings as in our Annual Report.

In the opinion of our management, all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation, have been included.  All intercompany transactions and balances with or among our subsidiaries have been eliminated.  Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.  Certain reclassifications have been made to the prior year's financial statements to conform to the current year’s presentation.

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 the condensed consolidated financial statements include the assessment of the collectability of rental revenue, purchase price allocations, useful lives of fixed assets and impairment of real estate and intangible assets.

Share amounts are presented in whole numbers, except where noted.

Recent Accounting Pronouncements

In August 2018, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which changes the fair value measurement disclosure requirements of FASB Accounting Standards Codification, or ASC, 820. This update is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. We do not expect the adoption of ASU 2018-13 to have a material impact on our consolidated financial statements.

EQUITY COMMONWEALTH

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for share-based payments granted to nonemployees for goods and services. This update is effective for fiscal years beginning after December 15, 2018, and for interim periods within those fiscal years. We adopted ASU 2018-07 on January 1, 2019, and the adoption did not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires more timely recognition of credit losses associated with financial assets. This update is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. We do not expect the adoption of ASU 2016-13 to have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASU 2016-02 supersedes previous leasing standards. For leases where we are the lessor, we account for these leases using an approach that is substantially equivalent to previous guidance prior to the adoption of ASU 2016-02. Additionally, under ASU 2016-02, lessors may only capitalize incremental direct leasing costs. For leases in which we are the lessee, we recognize a right-of-use asset and a lease liability equal to the present value of the minimum lease payments, with rent expense being recognized on a straight-line basis and the right of use asset being reduced when lease payments are made.

In July 2018, the FASB issued ASU 2018-11 to provide entities with relief from the costs of implementing certain aspects of ASU 2016-02. The amendment to the new leases standard includes a practical expedient that provides lessors an option not to separate lease and non-lease components when certain criteria are met and instead account for those components as a single component under the new leases standard.  The amendment also provides a transition option that permits the application of the new guidance as of the adoption date rather than to all periods presented.  We elected the practical expedient to account for both our lease (primarily base rent) and non-lease (primarily tenant reimbursements) components as a single component under the leases standard and elected the new transition option. We adopted these pronouncements on January 1, 2019, and the adoption did not have a material impact on our consolidated financial statements, both as a lessor and as a lessee.

Certain reclassifications were made to conform the prior period to our presentation of the condensed consolidated statements of operations as a result of adopting ASU 2016-02. Amounts that were previously disclosed as "Tenant reimbursements and other income" are now included in "Rental revenue" and are no longer presented as a separate line item. Parking revenues that do not represent components of leases and were previously disclosed as "Rental income" are now included in "Other revenue." Subsequent to January 1, 2019, provisions for credit losses are included in "Rental revenue." Provisions for credit losses prior to January 1, 2019 were disclosed as "Operating expenses" and were not reclassified to conform prior periods to the current presentation.

Common Share Repurchases:

On March 13, 2019, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares over the twelve months following the date of authorization. During the nine months ended September 30, 2019, we did not repurchase any of our common shares under our share repurchase program. The $150.0 million of remaining authorization available under our share repurchase program as of September 30, 2019 is scheduled to expire on March 13, 2020.

During the nine months ended September 30, 2019 and 2018, certain of our employees surrendered 168,327 and 57,348 common shares owned by them, respectively, to satisfy their statutory tax withholding obligations in connection with the vesting of such common shares.

Note 7.  Noncontrolling Interest

Noncontrolling interest represents the portion of the OP Units not beneficially owned by the Company. The ownership of an OP Unit and a common share of beneficial interest have essentially the same economic characteristics. Distributions with respect to OP Units will generally mirror distributions with respect to the Company’s common shares. Unitholders (other than the Company) generally have the right, commencing six months from the date of issuance of such OP Units, to cause the Operating Trust to redeem their OP Units in exchange for cash or, at the option of the Company, common shares of the Company on a one-for-one basis. As sole trustee, the Company has the sole discretion to elect whether the redemption right will be satisfied by the Company in cash or the Company’s common shares. As a result, the Noncontrolling interest is classified as permanent equity. As of September 30, 2019, the portion of the Operating Trust not beneficially owned by the Company is in the form of OP Units and LTIP Units (see Note 10 for a description of LTIP Units). LTIP Units may be subject to additional vesting requirements.

The following table presents the changes in Equity Commonwealth’s issued and outstanding common shares and units for the nine months ended September 30, 2019:

	Common Shares	OP Units and LTIP Units	Total
Outstanding at January 1, 2019	121,572,155	45,720	121,617,875
Repurchase of shares	(168,327)	—	(168,327)
Restricted share grants, time-based LTIP Unit grants and vested restricted stock units, net of forfeitures	520,371	2,940	523,311
Outstanding at September 30, 2019	121,924,199	48,660	121,972,859
Noncontrolling ownership interest in the Operating Trust			0.04	%

The carrying value of the Noncontrolling interest is allocated based on the number of OP Units and LTIP Units in proportion to the number of OP Units and LTIP Units plus the number of common shares. We adjust the Noncontrolling interest balance at the end of each period to reflect the noncontrolling partners’ interest in the net assets of the Operating Trust. Net income is allocated to the Noncontrolling interest in the Operating Trust based on the weighted average ownership percentage during the period. Equity Commonwealth’s weighted average ownership interest in the Operating Trust was 99.96% and 99.96% for the three and nine months ended September 30, 2019, respectively.

Note 10. Share-Based Compensation

At our annual meeting of shareholders on June 20, 2019, our shareholders approved an amendment to the Equity Commonwealth 2015 Omnibus Incentive Plan to increase the number of common shares of beneficial interest authorized thereunder by 2,500,000.

Recipients of the Company’s restricted shares have the same voting rights as any other common shareholder. During the period of restriction, holders of unvested restricted shares are eligible to receive dividend payments on their shares at the same rate and on the same date as any other common shareholder.  The restricted shares are service based awards and vest over a four-year period.

Recipients of the Company’s restricted stock units, or RSUs, are entitled to receive dividends with respect to the common shares underlying the RSUs if and when the RSUs are earned, at which time the recipient will be entitled to receive an amount in cash equal to the aggregate amount of cash dividends that would have been paid in respect of the common shares underlying the recipient’s earned RSUs had such common shares been issued to the recipient on the first day of the performance period. To the extent that an award does not vest, the dividends related to unvested RSUs will be forfeited. The RSUs are market-based awards with a service condition and recipients may earn RSUs based on the Company’s total shareholder return, or TSR, relative to the TSRs of the companies that comprise the NAREIT Office Index over a three-year performance period.

13

EQUITY COMMONWEALTH

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Following the end of the three-year performance period, the number of earned awards will be determined. The earned awards vest in two tranches with 50% of the earned award vesting following the end of the performance period on the date the Compensation Committee of our Board of Trustees, or the Committee, determines the level of achievement of the performance metric and the remaining 50% of the earned award vesting approximately one year thereafter, subject to the grant recipient’s continued employment. Compensation expense for the RSUs is determined using a Monte Carlo simulation model and is recognized ratably from the grant date to the vesting date of each tranche.

LTIP Units are a class of beneficial interests in the Operating Trust that may be issued to employees, officers or trustees of the Operating Trust, the Company or their subsidiaries. Time-based LTIP Units have the same general characteristics as restricted shares and market-based LTIP Units have the same general characteristics as RSUs. Each LTIP Unit will convert automatically into an OP Unit on a one-for-one basis when the LTIP Unit becomes vested and its capital account is equalized with the per-unit capital account of the OP Units. Holders of LTIP Units generally will be entitled to receive the same per-unit distributions as the other outstanding OP Units in the Operating Trust, except that market-based LTIP Units will not participate in distributions until expiration of the applicable performance period, at which time any earned market-based LTIP Units generally will become entitled to receive a catch-up distribution for the periods prior to such time.

2019 Equity Award Activity

During the nine months ended September 30, 2019, 384,811 RSUs vested, and, as a result, we issued 384,811 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 6).

On June 20, 2019, in accordance with the Company’s compensation plan for independent Trustees, the Committee awarded each of the nine independent Trustees $0.1 million in restricted shares or time-based LTIP Units as part of their compensation for the 2019-2020 year of service on the Board of Trustees. These awards equated to 2,940 shares or time-based LTIP Units per Trustee, for a total of 23,520 shares and 2,940 time-based LTIP Units, valued at $34.01 per share and unit, the closing price of our common shares on the New York Stock Exchange (NYSE) on that day. These shares and time-based LTIP Units vest one year after the date of the award.

On January 29, 2019, the Committee approved grants in the aggregate amount of 112,359 restricted shares and 228,128 RSUs at target (568,609 RSUs at maximum) to the Company’s officers, certain employees and to Mr. Zell, the Chairman of our Board of Trustees, as part of their compensation for fiscal year 2018. The restricted shares granted on January 29, 2019 were valued at $31.77 per share, the closing price of our common shares on the NYSE on that day. The assumptions and fair value for the RSUs granted during the nine months ended September 30, 2019 are included in the following table on a per share basis.

2018 Equity Award Activity

During the nine months ended September 30, 2018, 141,605 RSUs vested, and, as a result, we issued 141,605 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 6).

On June 20, 2018, in accordance with the Company’s compensation plan for independent Trustees, the Committee awarded each of the nine independent Trustees $0.1 million in restricted shares or time-based LTIP Units as part of their compensation for the 2018-2019 year of service on the Board of Trustees. These awards equated to 3,200 shares or time-based LTIP Units per Trustee, for a total of 25,600 shares and 3,200 time-based LTIP Units, valued at $31.25 per share and unit, the closing price of our common shares on the New York Stock Exchange (NYSE) on that day. These shares and time-based LTIP Units vested one year after the date of the award.

On January 29, 2018, the Committee approved grants in the aggregate amount of 125,409 restricted shares and 254,615 RSUs at target (634,628 RSUs at maximum) to the Company’s officers, certain employees and to Mr. Zell, the Chairman of our Board of Trustees, as part of their compensation for fiscal year 2017. The restricted shares were valued at $29.78 per share, the

closing price of our common shares on the NYSE on the grant date. The RSUs were valued at $37.13 per share, their fair value on the grant date.

Outstanding Equity Awards

As of September 30, 2019, the estimated future compensation expense for all unvested restricted shares and time-based LTIP Units was $7.0 million. Compensation expense for the restricted share and time-based LTIP Unit awards is being recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. The weighted average period over which the future compensation expense will be recorded for the restricted shares and time-based LTIP units is approximately 2.3 years.

As of September 30, 2019, the estimated future compensation expense for all unvested RSUs and market-based LTIP Units was $14.0 million. The weighted average period over which the future compensation expense will be recorded for the RSUs and market-based LTIP Units is approximately 2.2 years.

During the three months ended September 30, 2019 and 2018, we recorded $3.4 million and $5.2 million, respectively, and during the nine months ended September 30, 2019 and 2018, we recorded $11.1 million and $15.7 million, respectively, of compensation expense, net of forfeitures, in general and administrative expense for grants to our trustees and employees related to our equity compensation plans. Compensation expense recorded during the nine months ended September 30, 2019 and 2018 includes $0.8 million and $0.4 million, respectively, of accelerated vesting due to staffing reductions. Forfeitures are recognized as they occur. At September 30, 2019, 2,859,628 shares/units remain available for issuance under the Equity Commonwealth 2015 Omnibus Incentive Plan, as amended.

Note 11.  Fair Value of Assets and Liabilities

As of September 30, 2019, we do not have any assets or liabilities measured at fair value.

Financial Instruments

Our financial instruments include our cash and cash equivalents, restricted cash, marketable securities, senior unsecured debt and mortgage note payable.  At September 30, 2019 and December 31, 2018, the fair value of these additional financial instruments were not materially different from their carrying values, except as follows (in thousands):

	September 30, 2019				December 31, 2018
	Principal Balance		Fair Value		Principal Balance		Fair Value
Senior unsecured debt and mortgage note payable	$	25,579	$	26,321	$	276,000	$	283,214

The fair values of our senior notes are based on quoted market prices (level 2 inputs), and the fair value of our mortgage note payable is based on estimates using discounted cash flow analyses and currently prevailing interest rates adjusted by credit risk spreads (level 3 inputs).

Other financial instruments that potentially subject us to concentrations of credit risk consist principally of rents receivable. As of September 30, 2019, we have one tenant that is responsible for 23.0% of our total annualized rents, and no other single tenant of ours is responsible for more than 10.0% of our total annualized rents.

OVERVIEW

We are an internally managed and self-advised REIT primarily engaged in the ownership and operation of office properties in the United States. We were formed in 1986 under Maryland law. The Company operates as what is commonly referred to as an UPREIT, conducting substantially all of its activities through the Operating Trust. As of September 30, 2019, the Company beneficially owned 99.96% of the outstanding OP Units.

At September 30, 2019, our portfolio consisted of 7 properties (12 buildings), with a combined 2.5 million square feet and a total undepreciated book value of $658.3 million, and a depreciated book value of $460.5 million. As of September 30, 2019, we had $3.2 billion of cash and cash equivalents.

As of September 30, 2019, our overall portfolio was 93.5% leased. During the three months ended September 30, 2019, we entered into leases, excluding leasing activity for assets during the quarter in which the asset was sold, for 298,000 square feet, including lease renewals for 182,000 square feet and new leases for 116,000 square feet.  Renewal leases entered into during the three months ended September 30, 2019 had weighted average cash and GAAP rental rates that were approximately 12.7% lower and 8.5% lower, respectively, compared to prior rental rates for the same space, and new leases entered into during the three months ended September 30, 2019 had weighted average cash and GAAP rental rates that were approximately 11.6% higher and 26.4% higher, respectively, than prior rental rates for the same space.  The change in GAAP rents is different than the change in cash rents due to differences in the amount of rent abatements, the magnitude and timing of contractual rent increases over the lease term, and the length of term for the newly executed leases compared to the prior leases.

During the nine months ended September 30, 2019, we sold three properties (six buildings) with a combined 2.7 million square feet for an aggregate gross sales price of $812.1 million, excluding credits and closing costs.  For more information regarding these transactions, see Note 3 to the notes to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. As we have sold assets, our income from operations has declined.

On September 24, 2019, our Board of Trustees declared a special, one-time cash distribution of $3.50 per common share/unit to shareholders/unitholders of record on October 7, 2019. On October 23, 2019, we paid this distribution to such shareholders/unitholders in the aggregate amount of $427.7 million.

We have engaged CBRE, Inc., or CBRE, to provide property management services for our properties. We pay CBRE a property-by-property management fee and may engage CBRE from time-to-time to perform project management services, such as coordinating and overseeing the completion of tenant improvements and other capital projects at the properties. We reimburse CBRE for certain expenses incurred in the performance of its duties, including certain personnel and equipment costs. For the three months ended September 30, 2019 and 2018, we incurred expenses of $1.1 million and $2.1 million, respectively, and for the nine months ended September 30, 2019 and 2018, we incurred expenses of $4.1 million and $7.3 million, respectively, related to our property management agreement with CBRE, for property management fees, typically calculated as a percentage of property revenues, and salary and benefits reimbursements for property personnel, such as property managers, engineers and maintenance staff.  As of September 30, 2019 and December 31, 2018, we had amounts payable pursuant to these services of $0.5 million and $0.8 million, respectively.

We continue to execute our office repositioning strategy to own and acquire at a discount to replacement cost high-quality, multi-tenant office assets in markets and sub-markets with favorable long-term supply and demand fundamentals. We expect our efforts in the office sector to continue to be primarily focused on larger buildings in central business districts and major urban areas that offer an attractive quality of life, including opportunities for tenants to live and play in close proximity to where they work, with a preference for markets that have above average limitations on new supply. We currently target such efforts towards acquiring portfolios of properties or pursuing other large acquisitions as opposed to purchasing individual properties, although we may acquire individual properties if opportunities to do so are consistent with our strategy. The set of opportunities that we pursue in the future may include acquisitions in the office sector as well as other property types in order to create a foundation for long-term growth.

In executing this strategy, we may sell additional properties, depending on market conditions. With the progress we have had executing dispositions, and the strength and liquidity of our balance sheet, we are in a position to increasingly shift our focus to capital allocation. We intend to use our capital to purchase new properties or businesses, repay debt, buy back common shares or make other investments or distributions that further our long-term strategic goals.

We may be unable to identify suitable opportunities. If we do not redeploy capital, we will strive to achieve a sale or liquidation of the Company in a manner that optimizes shareholder value. We are unable to predict if or when we will make a determination to sell or liquidate the Company.

Property Operations

Leased occupancy data for 2019 and 2018 are as follows (square feet in thousands):

	All Properties(1)				Comparable Properties(2)
	As of September 30,				As of September 30,

(1)Excludes properties sold or classified as held for sale as of the end of the period. 

(2)Based on properties owned continuously from January 1, 2018 through September 30, 2019, and excludes properties sold or classified as held for sale as of the end of the period.

(3)Percent leased includes space subject to leases that have commenced, space being fitted out for occupancy pursuant to existing leases, and space that is leased but not occupied or is being offered for sublease by tenants.

The weighted average lease term based on square feet for leases entered into during the three months ended September 30, 2019 was 4.6 years.  Commitments made for leasing expenditures and concessions, such as tenant improvements and leasing commissions, for leases entered into during the three months ended September 30, 2019 totaled $13.2 million, or $44.27 per square foot on average (approximately $9.60 per square foot per year of the lease term).

As of September 30, 2019, approximately 0.8% of our leased square feet and 0.6% of our annualized rental revenue, determined as set forth below, are included in leases scheduled to expire through December 31, 2019.  Renewal and new leases and rental rates at which available space may be relet in the future will depend on prevailing market conditions at the times these leases are negotiated.  We believe that the in-place cash rents for leases expiring for the remainder of 2019, that have not

19

been backfilled, are at market. Lease expirations by year, as of September 30, 2019, are as follows (square feet and dollars in thousands):

(1)Leased Square Feet as of September 30, 2019 includes space subject to leases that have commenced, space being fitted out for occupancy pursuant to existing leases, and space which is leased but is not occupied or is being offered for sublease by tenants. The Leased Square Feet Expiring corresponds to the latest-expiring signed lease for a given suite. Thus, backfilled suites expire in the year stipulated by the new lease. 

(2)Annualized rental revenue is annualized contractual rents from our tenants pursuant to leases which have commenced as of September 30, 2019, plus estimated recurring expense reimbursements. Annualized rental revenue excludes lease value amortization, straight line rent adjustments, abated (free) rent periods and parking revenue. We calculate annualized rental revenue by aggregating the recurring billings outlined above for the most recent month during the quarter reported, adding abated rent, and multiplying the sum by 12 to provide an estimation of near-term potentially-recurring revenues.  Annualized rental revenue is a forward-looking non-GAAP measure.  Annualized rental revenue cannot be reconciled to a comparable GAAP measure without unreasonable efforts, primarily due to the fact that it is calculated from the billings of tenants in the most recent month at the most recent rental rates during the quarter reported, whereas historical GAAP measures include billings from a potentially different group of tenants over multiple months at potentially different rental rates.

The principal source of funds for our operations is rents received from tenants at our properties.  Rents are generally received from our tenants monthly in advance.  As of September 30, 2019, tenants representing 2.0% or more of our total annualized rental revenue were as follows (square feet in thousands):

Tenant		Square Feet(1)	% of Total Leased Square Feet(1)		% of Annualized Rental Revenue(2)		Weighted Average Remaining Lease Term

(3)During the third quarter of 2018, an affiliate of Amazon.com, Inc. entered into a new 16-year lease for 429,012 square feet, including all of the Expedia, Inc. space. The lease commences in 2020.

(4)Georgetown University's leased space includes 111,600 square feet that are sublet to the British International School of Washington. During the fourth quarter of 2017, the British International School of Washington committed to lease the 111,600 square feet space through September 30, 2037 directly from EQC. The lease commenced on October 1, 2019. The 2.0 year weighted average remaining lease term for Georgetown University applies to the 128,875 square feet that Georgetown University continues to occupy after September 30, 2019.

(5)The weighted average remaining lease term including leases that have been backfilled with new tenants is 11.0 years.

Financing Activities

On June 28, 2019, we redeemed all $250.0 million of our 5.875% senior unsecured notes due 2020 and recognized a loss on early extinguishment of debt of $6.4 million for the nine months ended September 30, 2019 from prepayment fees, the write off of unamortized deferred financing fees and the write off of an unamortized discount. As of September 30, 2019, our only debt consists of one $25.6 million mortgage note payable.

(1)Comparable properties consist of 7 properties (12 buildings) we owned continuously from July 1, 2018 to September 30, 2019.

(2)Other properties consist of properties sold or classified as held for sale as of the end of the period.

(3)Certain reclassifications were made to conform the prior period to our presentation of the condensed consolidated statements of operations due to the impact of adopting ASU 2016-02. Amounts that were previously disclosed as "Tenant reimbursements and other income" are now included in "Rental revenue" and are no longer presented as a separate line item. Parking revenues that do not represent components of leases and were previously disclosed as "Rental income" are now included in "Other revenue." Subsequent to January 1, 2019, provisions for credit losses are included in "Rental revenue." Provisions for credit losses prior to January 1, 2019 were disclosed as "Operating expenses" and were not reclassified to conform prior periods to the current presentation.

(4)We define net operating income, or NOI, as shown above, as income from our real estate including lease termination fees received from tenants less our property operating expenses.  NOI excludes amortization of capitalized tenant improvement costs and leasing commissions and corporate level expenses.  For a discussion of why we consider NOI to be an appropriate supplemental measure to net income as well as a reconciliation of NOI to net income, the most directly comparable financial measure under GAAP reported on our consolidated financial statements, please see "- Liquidity and Capital Resources - Property Net Operating Income (NOI)."

Rental revenue. Rental revenue decreased $19.8 million, or 45.2%, in the 2019 period, compared to the 2018 period, primarily due to the properties sold in 2019 and 2018. Rental revenue at the comparable properties increased $0.7 million, or 2.9%, in the 2019 period, compared to the 2018 period, primarily due to leasing activity and a $0.3 million increase in escalations and real estate tax recoveries.

Rental revenue includes (reductions) increases for straight line rent adjustments totaling $(0.5) million in the 2019 period and $1.4 million in the 2018 period, and net increases for amortization of acquired real estate leases and assumed real estate lease obligations totaling $39,000 in the 2019 period and $4,000 in the 2018 period. Rental revenue also includes the recognition of lease termination fees totaling $11,000 in the 2019 period and $0.4 million in the 2018 period.

22

Other revenue. Other revenue, which primarily includes parking revenue, decreased $0.4 million, or 11.7%, in the 2019 period, compared to the 2018 period, primarily due to the properties sold in 2019 and 2018. Other revenue, increased $0.2 million, or 6.5%, at the comparable properties in the 2019 period, compared to the 2018 period, primarily due to increased parking revenue during the 2019 period.

Operating expenses. Operating expenses decreased $10.3 million, or 51.0%, in the 2019 period, compared to the 2018 period, primarily due to the properties sold in 2019 and 2018. Operating expenses at the comparable properties were approximately the same in the 2019 period as compared to the 2018 period. The slight decrease in operating expenses is primarily due to a $0.3 million decrease in utility expense, partially offset by a $0.1 million increase in real estate tax expense and a $0.1 million increase in maintenance and repairs.

Depreciation and amortization. Depreciation and amortization decreased $5.3 million, or 47.4%, in the 2019 period, compared to the 2018 period primarily due to properties sold in 2019 and 2018.

General and administrative. General and administrative expenses decreased $2.4 million, or 21.8%, in the 2019 period, compared to the 2018 period, primarily due to a $1.8 million decrease in share-based compensation expense and a $0.6 million decrease in payroll expenses as a result of a staffing reduction, partially offset by $0.2 million of compensation expenses related to severance expense incurred in the 2019 period.

Interest and other income, net. Interest and other income, net increased $6.8 million, or 53.7% in the 2019 period, compared to the 2018 period, primarily due to $4.7 million of additional interest received on higher invested balances and higher average interest rates in 2019, and a $2.1 million loss on the sale of a real estate mortgage receivable in 2018. This mortgage receivable of $7.7 million represented mortgage financing we provided upon the sale of three properties in 2013.

Interest expense. Interest expense decreased $4.8 million, or 93.7%, in the 2019 period, compared to the 2018 period, primarily due to the termination of our credit agreement in December 2018, the redemption in June 2019 of all $250 million of our 5.875% senior unsecured notes due 2020 and a decrease in amortization of deferred financing fees.

Gain on sale of properties, net. Gain on sale of properties, net decreased $18.9 million, or 90.7%, in the 2019 period, as compared to the 2018 period. Gain on sale of properties, net in the 2019 period primarily related to adjustments to prior period sales. Gain on sale of properties, net in the 2018 period primarily related to the following (dollars in thousands):

Asset	Gain on Sale, Net
777 East Eisenhower Parkway	$	5,321
8750 Bryn Mawr Avenue	15,609
	$	20,930

Income tax benefit (expense). In the 2019 period, we recorded income tax benefit of $0.5 million, and, in the 2018 period, we recorded income tax expense of $0.1 million. The change in income taxes is primarily due to a decrease in state and local taxes as a result of the sale of properties.

Net income attributable to noncontrolling interest. In 2019, 2018 and 2017, we granted LTIP Units to certain of our trustees and employees. The net income attributable to noncontrolling interest of $10,000 in the 2019 period and $13,000 in the 2018 period related to the allocation of net income to the LTIP Unit holders.

(3)Certain reclassifications were made to conform the prior period to our presentation of the condensed consolidated statements of operations due to the impact of adopting ASU 2016-02. Amounts that were previously disclosed as "Tenant reimbursements and other income" are now included in "Rental revenue" and are no longer presented as a separate line item. Parking revenues that do not represent components of leases and were previously disclosed as "Rental income" are now included in "Other revenue." Subsequent to January 1, 2019, provisions for credit losses are included in "Rental revenue." Provisions for credit losses prior to January 1, 2019 were disclosed as "Operating expenses" and were not reclassified to conform prior periods to the current presentation.

(4)See Note 4 on page 22 for further information regarding NOI.

Rental revenue. Rental revenue decreased $51.2 million, or 35.4%, in the 2019 period, compared to the 2018 period, primarily due to the properties sold in 2019 and 2018. Rental revenue at the comparable properties increased $6.2 million, or 9.1%, in the 2019 period, compared to the 2018 period, primarily due to leasing activity, a $2.1 million increase in lease termination fees and a $2.2 million increase in escalations and real estate tax recoveries.

Rental revenue includes increases for straight line rent adjustments totaling $0.3 million in the 2019 period and $4.0 million in the 2018 period, and net increases (reductions) for amortization of acquired real estate leases and assumed real estate lease obligations totaling $0.1 million in the 2019 period and $(0.1) million in the 2018 period. Rental revenue also includes the recognition of lease termination fees totaling $2.2 million in the 2019 period and $2.9 million in the 2018 period.

Other revenue. Other revenue, which primarily includes parking revenue, decreased $1.1 million, or 11.5%, in the 2019 period, compared to the 2018 period, primarily due to the properties sold in 2019 and 2018. Other revenue, increased $0.5 million, or

24

6.5%, at the comparable properties in the 2019 period, compared to the 2018 period primarily due to increased parking revenue during the 2019 period.

Operating expenses. Operating expenses decreased $27.7 million, or 43.0%, in the 2019 period, compared to the 2018 period, primarily due to the properties sold in 2019 and 2018. Operating expenses increased $0.9 million, or 3.2%, at the comparable properties primarily due to a $1.4 million increase in real estate tax expense, partially offset by a $0.8 million decrease in utility expense.

Depreciation and amortization. Depreciation and amortization decreased $16.1 million, or 42.2%, in the 2019 period, compared to the 2018 period, primarily due to the properties sold in 2019 and 2018.

General and administrative. General and administrative expenses decreased $5.3 million, or 15.0%, in the 2019 period, compared to the 2018 period, primarily due to a $5.1 million decrease in share-based compensation expense and a $1.4 million decrease in payroll expenses as a result of a staffing reduction, partially offset by a $1.6 million increase in compensation expenses related to severance from $1.8 million in the 2018 period to $3.4 million in the 2019 period.

Loss on asset impairment. We recorded impairment charges of $12.1 million in the 2018 period related to 777 East Eisenhower Parkway and 97 Newberry Road, based upon the shortening of our expected period of ownership and updated market information in accordance with our impairment analysis procedures. We did not record any impairment charges in the 2019 period.

Interest and other income, net. Interest and other income, net increased $26.8 million, or 86.2%, in the 2019 period, compared to the 2018 period, primarily due to $18.6 million of additional interest received on higher invested balances and higher average interest rates in 2019, a $5.0 million loss on the sale of marketable securities in the 2018 period and a $2.1 million loss on the sale of a real estate mortgage receivable in 2018. This mortgage receivable of $7.7 million represented mortgage financing we provided upon the sale of three properties in 2013.

Interest expense. Interest expense decreased $13.0 million, or 60.1%, in the 2019 period, compared to the 2018 period, primarily due to the prepayment in March 2018 of all $175.0 million of our 5.75% senior unsecured notes due 2042, the redemption at par of the total $400.0 million outstanding under our 5-year and 7-year term loans in May 2018, the termination of our credit agreement in December 2018, the redemption in June 2019 of all $250 million of our 5.875% senior unsecured notes due 2020 and a decrease in amortization of deferred financing fees.

Loss on early extinguishment of debt. The loss on early extinguishment of debt of $6.4 million in the 2019 period reflects the write off of unamortized deferred financing fees, the write off of an unamortized discount and prepayment fees related to the redemption of all $250 million of our 5.875% senior unsecured notes due 2020. The loss on early extinguishment of debt of $6.4 million in the 2018 period reflects the write off of unamortized deferred financing fees related to our redemption at par of the total $400.0 million outstanding under our 5-year and 7-year term loans and the write off of unamortized deferred financing fees related to our repayment at par of all $175 million of our 5.75% senior unsecured notes due 2042.

Gain on sale of properties, net. Gain on sale of properties, net increased $169.1 million, or 66.8%, in the 2019 period, compared to the 2018 period. Gain on sale of properties, net in the 2019 period primarily related to the following (dollars in thousands):

Asset	Gain on Sale, Net
1735 Market Street	$	192,985
600 108th Avenue NE	149,009
Research Park	78,158
	$	420,152

5073, 5075, & 5085 S. Syracuse Street	42,762
1601 Dry Creek Drive	26,979
777 East Eisenhower Parkway	5,321
8750 Bryn Mawr Avenue	15,609
	$	253,060

Income tax expense. Income tax expense decreased $1.5 million, or 57.2%, in the 2019 period, compared to the 2018 period, primarily due to a decrease in state and local taxes as a result of the sale of properties.

Net income attributable to noncontrolling interest. In 2019, 2018 and 2017, we granted LTIP Units to certain of our trustees and employees. The net income attributable to noncontrolling interest of $0.2 million in the 2019 period and $0.1 million in the 2018 period related to the allocation of net income to the LTIP Unit holders.

LIQUIDITY AND CAPITAL RESOURCES

Our Operating Liquidity and Resources

As of September 30, 2019, we had $3.2 billion of cash and cash equivalents.  We expect to use our cash balances, cash flow from our operations and proceeds of any future property sales to fund our operations, make distributions, repurchase our common shares, acquire assets or businesses, fund tenant improvements and leasing costs and for other general business purposes.  We believe our cash balances and the cash flow from our operations will be sufficient to fund our ordinary course activities.

Our future cash flows from operating activities will depend primarily upon our:

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

•ability to control operating and financing expense increases at our properties; and

•ability to purchase additional properties, which produce rents, less property operating expenses, in excess of our costs of acquisition capital.

Volatility in energy costs and real estate taxes may cause our future operating expenses to fluctuate; however, the impact of these fluctuations is expected to be partially offset by the pass through of operating expenses to our tenants pursuant to lease terms, although there can be no assurance that we will be able to successfully offset these expenses or that doing so would not negatively impact our competitive position or business. 

Cash flows provided by (used in) operating, investing and financing activities were $74.1 million, $1.0 billion and $(268.3) million, respectively, for the nine months ended September 30, 2019, and $50.5 million, $943.6 million and $(671.7) million, respectively, for the nine months ended September 30, 2018.  Changes in these three categories of our cash flows between 2019 and 2018 are primarily related to a decrease in property net operating income (as a result of property dispositions), an increase in interest income (as a result of additional interest received on higher invested balances and higher average interest rates in 2019), real estate improvements, dispositions of properties, proceeds from sales and maturities of marketable securities, repayments of debt and repurchase of our common shares.

Our Investment and Financing Liquidity and Resources

On June 28, 2019, we redeemed all $250.0 million of our 5.875% senior unsecured notes due 2020 and recognized a loss on early extinguishment of debt of $6.4 million for the nine months ended September 30, 2019 from prepayment fees, the write off of unamortized deferred financing fees and the write off of an unamortized discount. As of September 30, 2019, our only debt consists of one $25.6 million mortgage note payable.

On September 24, 2019, our Board of Trustees declared a special, one-time cash distribution of $3.50 per common share/unit to shareholders/unitholders of record on October 7, 2019. On October 23, 2019, we paid this distribution to such shareholders/unitholders in the aggregate amount of $427.7 million.

During the nine months ended September 30, 2019, we paid an aggregate of $6.0 million of distributions on our series D preferred shares.  On October 11, 2019, our Board of Trustees declared a dividend of $0.40625 per series D preferred share, which will be paid on November 15, 2019 to shareholders of record on October 31, 2019.

On March 13, 2019, our Board of Trustees authorized the repurchase of up to $150.0 million of our outstanding common shares over the twelve months following the date of authorization. During the nine months ended September 30, 2019, we did not repurchase any of our common shares under our share repurchase program. The $150.0 million of remaining authorization available under our share repurchase program as of September 30, 2019 is scheduled to expire on March 13, 2020.

27

Our outstanding debt maturity and interest rate as of September 30, 2019, were as follows (dollars in thousands):

	Scheduled Principal Payments During Period
Year	Secured Fixed Rate Debt(1)		Interest Rate(2)
2019	$	146	5.7	%
2020	597		5.7	%
2021	24,836		5.7	%
Thereafter	—		—	%
	$	25,579	5.7	%

(1)Total debt outstanding as of September 30, 2019, including net unamortized premiums and net unamortized deferred financing costs, was $25,896.

(2)Contractual interest rate.

For further information about our indebtedness, see Note 5 to the notes to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

As the maturity date of our debt approaches, we may explore alternatives to repay the amount due. Such alternatives may include using our cash balances, incurring additional debt and issuing new equity securities, and entering into a new revolving credit facility. We have an effective shelf registration statement that allows us to issue certain types of public securities on an expedited basis, but it does not apply to debt securities nor does it assure that there will be buyers for any such securities.

We believe that we will have access to various types of financings, including debt or equity offerings, to fund any future acquisitions and to pay our debt and other obligations as they become due. The completion and the costs of any future debt transactions will depend primarily upon market conditions and our credit ratings at such time. We have no control over market conditions. Our credit ratings will depend upon evaluations by credit rating agencies of our business practices and plans and, in particular, whether we appear to have the ability to maintain our earnings, to space 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 foreseeable adverse changes. We intend to conduct our business activities in a manner which will continue to afford us reasonable access to capital for investment and financing activities. However, there can be no assurance regarding our ability to complete any debt or equity offerings or that our cost of any future public or private financings will not increase.

During the nine months ended September 30, 2019, we sold three properties (six buildings) with a combined 2.7 million square feet for an aggregate gross sales price of $812.1 million, excluding credits and closing costs.  For more information regarding these transactions, see Note 3 to the notes to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

During the three and nine months ended September 30, 2019 and 2018, amounts capitalized at our properties, including properties sold or classified as held for sale, for tenant improvements, leasing costs and building improvements were as follows (amounts in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2019		2018		2019		2018
Tenant improvements(1)	$	707	$	11,490	$	5,648	$	36,170
Leasing costs(2)	3,056		11,699		4,273		19,450
Building improvements(3)	804		2,223		4,388		7,110

(1)Tenant improvements include capital expenditures to improve tenants’ spaces.

(2)Leasing costs include leasing commissions and related legal expenses.

(3)Building improvements generally include expenditures to replace obsolete building components and expenditures that extend the useful life of existing assets. Tenant-funded capital expenditures are excluded.

28

During the three months ended September 30, 2019, commitments made for expenditures in connection with leasing space at our properties, excluding leasing activity for assets during the quarter in which the asset was sold or classified as held for sale, were as follows (dollar and square foot measures in thousands):

	New Leases		Renewals		Total
Rentable square feet leased during the period	116		182		298
Tenant improvements and leasing commissions	$	11,549	$	1,647	$	13,196
Tenant improvements and leasing commissions per rentable square foot	$	99.56	$	9.05	$	44.27
Weighted average lease term by square foot (years)	7.3		2.9		4.6
Total tenant improvements and leasing commissions per rentable square foot per year	$	13.55	$	3.15	$	9.60

Debt Covenants

After the redemption of all $250 million of our 5.875% senior unsecured notes due 2020 on June 28, 2019, we no longer have any notes outstanding under the Indenture, and we are no longer required to maintain the financial ratio covenants prescribed in the Indenture. As a result, we are no longer rated by the debt rating agencies.

Off Balance Sheet Arrangements

As of September 30, 2019, we had no off balance sheet arrangements that have had or that we expect would be reasonably likely to have a future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.  We had no swaps or hedges as of September 30, 2019.

Funds from Operations (FFO) and Normalized FFO

We compute FFO in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT. NAREIT defines FFO as net income (loss), calculated in accordance with GAAP, excluding real estate depreciation and amortization, gains (or losses) from sales of depreciable property, impairment of depreciable real estate, and our portion of these items related to equity investees and non-controlling interests.  Our calculation of Normalized FFO differs from NAREIT’s definition of FFO because we exclude certain items that we view as nonrecurring or impacting comparability from period to period.  We consider FFO and Normalized FFO to be appropriate measures of operating performance for a REIT, along with net income, net income attributable to Equity Commonwealth common shareholders and cash flow from operating activities.

We believe that FFO and Normalized FFO provide useful information to investors because by excluding the effects of certain historical amounts, such as depreciation expense, FFO and Normalized FFO may facilitate a comparison of our operating performance between periods and with other REITs.  FFO and Normalized FFO do not represent cash generated by operating activities in accordance with GAAP and should not be considered as alternatives to net income, net income attributable to Equity Commonwealth common shareholders or cash flow from operating activities, determined in accordance with GAAP, or as indicators of our financial performance or liquidity, nor are these measures necessarily indicative of sufficient cash flow to fund all of our needs.  These measures should be considered in conjunction with net income, net income attributable to Equity Commonwealth common shareholders and cash flow from operating activities as presented in our condensed consolidated statements of operations, condensed consolidated statements of comprehensive income and condensed consolidated statements of cash flows.  Other REITs and real estate companies may calculate FFO and Normalized FFO differently than we do.

The following table provides a reconciliation of net income to FFO attributable to Equity Commonwealth common shareholders and unitholders and a calculation to Normalized FFO attributable to Equity Commonwealth common shareholders and unitholders (in thousands):

Property Net Operating Income (NOI)

We use property net operating income, or NOI, to evaluate the performance of our properties. We define NOI as income from our real estate including lease termination fees received from tenants less our property operating expenses. NOI excludes amortization of capitalized tenant improvement costs and leasing commissions and corporate level expenses.

The following table includes the reconciliation of NOI to net income, the most directly comparable financial measure under GAAP reported in our consolidated financial statements.  We consider NOI to be an appropriate supplemental measure to net income because it may help to understand the operations of our properties.  We use NOI internally to evaluate property level performance, and we believe that NOI provides useful information to investors regarding our results of operations because it reflects only those income and expense items that are incurred at the property level and may facilitate comparisons of our operating performance between periods and with other REITs.  NOI does not represent cash generated by operating activities in accordance with GAAP and should not be considered as an alternative to net income, net income attributable to Equity Commonwealth common shareholders or cash flow from operating activities, determined in accordance with GAAP, or as an indicator of our financial performance or liquidity, nor is this measure necessarily indicative of sufficient cash flow to fund all of our needs.  This measure should be considered in conjunction with net income, net income attributable to Equity Commonwealth common shareholders and cash flow from operating activities as presented in our consolidated statements of operations, consolidated statements of comprehensive income and consolidated statements of cash flows.  Other REITs and real estate companies may calculate NOI differently than we do.

Business

Business

Equity Commonwealth, or the Company, is a real estate investment trust, or REIT, formed in 1986 under the laws of the State of Maryland. Our business is primarily the ownership and operation of office properties in the United States.

On November 10, 2016, the Company converted to what is commonly referred to as an umbrella partnership real estate investment trust, or UPREIT. In connection with this conversion, the Company contributed substantially all of its assets to EQC Operating Trust, a Maryland real estate investment trust, or the Operating Trust, and the Operating Trust assumed substantially all of the Company’s liabilities pursuant to a contribution and assignment agreement between the Company and the Operating Trust.

The Company now conducts and intends to continue to conduct substantially all of its activities through the Operating Trust. The Company beneficially owned 99.96% of the outstanding shares of beneficial interest, designated as units, in the Operating Trust, or OP Units, as of September 30, 2019, and the Company is the sole trustee of the Operating Trust.  As the sole trustee, the Company generally has the power under the declaration of trust of the Operating Trust to manage and conduct the business of the Operating Trust, subject to certain limited approval and voting rights of other holders of OP Units.

At September 30, 2019, our portfolio consisted of 7 properties (12 buildings), with a combined 2.5 million square feet. As of September 30, 2019, we had $3.2 billion of cash and cash equivalents.

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying condensed consolidated financial statements of EQC have been prepared without audit.  Certain information and footnote 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 appropriate.  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, or our Annual Report, for the year ended December 31, 2018.  Capitalized terms used, but not defined in this Quarterly Report, have the same meanings as in our Annual Report.

In the opinion of our management, all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation, have been included.  All intercompany transactions and balances with or among our subsidiaries have been eliminated.  Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.  Certain reclassifications have been made to the prior year's financial statements to conform to the current year’s presentation.

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 the condensed consolidated financial statements include the assessment of the collectability of rental revenue, purchase price allocations, useful lives of fixed assets and impairment of real estate and intangible assets.

Share amounts are presented in whole numbers, except where noted.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In August 2018, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which changes the fair value measurement disclosure requirements of FASB Accounting Standards Codification, or ASC, 820. This update is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. We do not expect the adoption of ASU 2018-13 to have a material impact on our consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for share-based payments granted to nonemployees for goods and services. This update is effective for fiscal years beginning after December 15, 2018, and for interim periods within those fiscal years. We adopted ASU 2018-07 on January 1, 2019, and the adoption did not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires more timely recognition of credit losses associated with financial assets. This update is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. We do not expect the adoption of ASU 2016-13 to have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASU 2016-02 supersedes previous leasing standards. For leases where we are the lessor, we account for these leases using an approach that is substantially equivalent to previous guidance prior to the adoption of ASU 2016-02. Additionally, under ASU 2016-02, lessors may only capitalize incremental direct leasing costs. For leases in which we are the lessee, we recognize a right-of-use asset and a lease liability equal to the present value of the minimum lease payments, with rent expense being recognized on a straight-line basis and the right of use asset being reduced when lease payments are made.

In July 2018, the FASB issued ASU 2018-11 to provide entities with relief from the costs of implementing certain aspects of ASU 2016-02. The amendment to the new leases standard includes a practical expedient that provides lessors an option not to separate lease and non-lease components when certain criteria are met and instead account for those components as a single component under the new leases standard.  The amendment also provides a transition option that permits the application of the new guidance as of the adoption date rather than to all periods presented.  We elected the practical expedient to account for both our lease (primarily base rent) and non-lease (primarily tenant reimbursements) components as a single component under the leases standard and elected the new transition option. We adopted these pronouncements on January 1, 2019, and the adoption did not have a material impact on our consolidated financial statements, both as a lessor and as a lessee.

Certain reclassifications were made to conform the prior period to our presentation of the condensed consolidated statements of operations as a result of adopting ASU 2016-02. Amounts that were previously disclosed as "Tenant reimbursements and other income" are now included in "Rental revenue" and are no longer presented as a separate line item. Parking revenues that do not represent components of leases and were previously disclosed as "Rental income" are now included in "Other revenue." Subsequent to January 1, 2019, provisions for credit losses are included in "Rental revenue." Provisions for credit losses prior to January 1, 2019 were disclosed as "Operating expenses" and were not reclassified to conform prior periods to the current presentation.

Marketable Securities

our marketable securities consisted of United States Treasury notes and were classified as available-for-sale. The United States Treasury notes matured in January and February 2019, and as of September 30, 2019, we do not have any marketable securities.

Share-Based Compensation

9 Months Ended

Sep. 30, 2019

Share-based Payment Arrangement [Abstract]

Share-Based Compensation

Share-Based Compensation

At our annual meeting of shareholders on June 20, 2019, our shareholders approved an amendment to the Equity Commonwealth 2015 Omnibus Incentive Plan to increase the number of common shares of beneficial interest authorized thereunder by 2,500,000.

Recipients of the Company’s restricted shares have the same voting rights as any other common shareholder. During the period of restriction, holders of unvested restricted shares are eligible to receive dividend payments on their shares at the same rate and on the same date as any other common shareholder.  The restricted shares are service based awards and vest over a four-year period.

Recipients of the Company’s restricted stock units, or RSUs, are entitled to receive dividends with respect to the common shares underlying the RSUs if and when the RSUs are earned, at which time the recipient will be entitled to receive an amount in cash equal to the aggregate amount of cash dividends that would have been paid in respect of the common shares underlying the recipient’s earned RSUs had such common shares been issued to the recipient on the first day of the performance period. To the extent that an award does not vest, the dividends related to unvested RSUs will be forfeited. The RSUs are market-based awards with a service condition and recipients may earn RSUs based on the Company’s total shareholder return, or TSR, relative to the TSRs of the companies that comprise the NAREIT Office Index over a three-year performance period.

Following the end of the three-year performance period, the number of earned awards will be determined. The earned awards vest in two tranches with 50% of the earned award vesting following the end of the performance period on the date the Compensation Committee of our Board of Trustees, or the Committee, determines the level of achievement of the performance metric and the remaining 50% of the earned award vesting approximately one year thereafter, subject to the grant recipient’s continued employment. Compensation expense for the RSUs is determined using a Monte Carlo simulation model and is recognized ratably from the grant date to the vesting date of each tranche.

LTIP Units are a class of beneficial interests in the Operating Trust that may be issued to employees, officers or trustees of the Operating Trust, the Company or their subsidiaries. Time-based LTIP Units have the same general characteristics as restricted shares and market-based LTIP Units have the same general characteristics as RSUs. Each LTIP Unit will convert automatically into an OP Unit on a one-for-one basis when the LTIP Unit becomes vested and its capital account is equalized with the per-unit capital account of the OP Units. Holders of LTIP Units generally will be entitled to receive the same per-unit distributions as the other outstanding OP Units in the Operating Trust, except that market-based LTIP Units will not participate in distributions until expiration of the applicable performance period, at which time any earned market-based LTIP Units generally will become entitled to receive a catch-up distribution for the periods prior to such time.

2019 Equity Award Activity

During the nine months ended September 30, 2019, 384,811 RSUs vested, and, as a result, we issued 384,811 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 6).

On June 20, 2019, in accordance with the Company’s compensation plan for independent Trustees, the Committee awarded each of the nine independent Trustees $0.1 million in restricted shares or time-based LTIP Units as part of their compensation for the 2019-2020 year of service on the Board of Trustees. These awards equated to 2,940 shares or time-based LTIP Units per Trustee, for a total of 23,520 shares and 2,940 time-based LTIP Units, valued at $34.01 per share and unit, the closing price of our common shares on the New York Stock Exchange (NYSE) on that day. These shares and time-based LTIP Units vest one year after the date of the award.

On January 29, 2019, the Committee approved grants in the aggregate amount of 112,359 restricted shares and 228,128 RSUs at target (568,609 RSUs at maximum) to the Company’s officers, certain employees and to Mr. Zell, the Chairman of our Board of Trustees, as part of their compensation for fiscal year 2018. The restricted shares granted on January 29, 2019 were valued at $31.77 per share, the closing price of our common shares on the NYSE on that day. The assumptions and fair value for the RSUs granted during the nine months ended September 30, 2019 are included in the following table on a per share basis.

	2019
Fair value of RSUs granted	$	39.65
Expected term (years)	4
Expected volatility	13.98		%
Risk-free rate	2.52		%

2018 Equity Award Activity

During the nine months ended September 30, 2018, 141,605 RSUs vested, and, as a result, we issued 141,605 common shares, prior to certain employees surrendering their common shares to satisfy tax withholding obligations (see Note 6).

On June 20, 2018, in accordance with the Company’s compensation plan for independent Trustees, the Committee awarded each of the nine independent Trustees $0.1 million in restricted shares or time-based LTIP Units as part of their compensation for the 2018-2019 year of service on the Board of Trustees. These awards equated to 3,200 shares or time-based LTIP Units per Trustee, for a total of 25,600 shares and 3,200 time-based LTIP Units, valued at $31.25 per share and unit, the closing price of our common shares on the New York Stock Exchange (NYSE) on that day. These shares and time-based LTIP Units vested one year after the date of the award.

On January 29, 2018, the Committee approved grants in the aggregate amount of 125,409 restricted shares and 254,615 RSUs at target (634,628 RSUs at maximum) to the Company’s officers, certain employees and to Mr. Zell, the Chairman of our Board of Trustees, as part of their compensation for fiscal year 2017. The restricted shares were valued at $29.78 per share, the

closing price of our common shares on the NYSE on the grant date. The RSUs were valued at $37.13 per share, their fair value on the grant date.

Outstanding Equity Awards

As of September 30, 2019, the estimated future compensation expense for all unvested restricted shares and time-based LTIP Units was $7.0 million. Compensation expense for the restricted share and time-based LTIP Unit awards is being recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. The weighted average period over which the future compensation expense will be recorded for the restricted shares and time-based LTIP units is approximately 2.3 years.

As of September 30, 2019, the estimated future compensation expense for all unvested RSUs and market-based LTIP Units was $14.0 million. The weighted average period over which the future compensation expense will be recorded for the RSUs and market-based LTIP Units is approximately 2.2 years.

During the three months ended September 30, 2019 and 2018, we recorded $3.4 million and $5.2 million, respectively, and during the nine months ended September 30, 2019 and 2018, we recorded $11.1 million and $15.7 million, respectively, of compensation expense, net of forfeitures, in general and administrative expense for grants to our trustees and employees related to our equity compensation plans. Compensation expense recorded during the nine months ended September 30, 2019 and 2018 includes $0.8 million and $0.4 million, respectively, of accelerated vesting due to staffing reductions. Forfeitures are recognized as they occur. At September 30, 2019, 2,859,628 shares/units remain available for issuance under the Equity Commonwealth 2015 Omnibus Incentive Plan, as amended.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements of EQC have been prepared without audit.  Certain information and footnote 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 appropriate.  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, or our Annual Report, for the year ended December 31, 2018.  Capitalized terms used, but not defined in this Quarterly Report, have the same meanings as in our Annual Report.

In the opinion of our management, all adjustments, which include only normal recurring adjustments considered necessary for a fair presentation, have been included.  All intercompany transactions and balances with or among our subsidiaries have been eliminated.  Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year.  Certain reclassifications have been made to the prior year's financial statements to conform to the current year’s presentation.

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 the condensed consolidated financial statements include the assessment of the collectability of rental revenue, purchase price allocations, useful lives of fixed assets and impairment of real estate and intangible assets.

Share amounts are presented in whole numbers, except where noted.

Recent Accounting Pronouncements

In August 2018, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which changes the fair value measurement disclosure requirements of FASB Accounting Standards Codification, or ASC, 820. This update is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. We do not expect the adoption of ASU 2018-13 to have a material impact on our consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for share-based payments granted to nonemployees for goods and services. This update is effective for fiscal years beginning after December 15, 2018, and for interim periods within those fiscal years. We adopted ASU 2018-07 on January 1, 2019, and the adoption did not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires more timely recognition of credit losses associated with financial assets. This update is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. We do not expect the adoption of ASU 2016-13 to have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASU 2016-02 supersedes previous leasing standards. For leases where we are the lessor, we account for these leases using an approach that is substantially equivalent to previous guidance prior to the adoption of ASU 2016-02. Additionally, under ASU 2016-02, lessors may only capitalize incremental direct leasing costs. For leases in which we are the lessee, we recognize a right-of-use asset and a lease liability equal to the present value of the minimum lease payments, with rent expense being recognized on a straight-line basis and the right of use asset being reduced when lease payments are made.

In July 2018, the FASB issued ASU 2018-11 to provide entities with relief from the costs of implementing certain aspects of ASU 2016-02. The amendment to the new leases standard includes a practical expedient that provides lessors an option not to separate lease and non-lease components when certain criteria are met and instead account for those components as a single component under the new leases standard.  The amendment also provides a transition option that permits the application of the new guidance as of the adoption date rather than to all periods presented.  We elected the practical expedient to account for both our lease (primarily base rent) and non-lease (primarily tenant reimbursements) components as a single component under the leases standard and elected the new transition option. We adopted these pronouncements on January 1, 2019, and the adoption did not have a material impact on our consolidated financial statements, both as a lessor and as a lessee.

Certain reclassifications were made to conform the prior period to our presentation of the condensed consolidated statements of operations as a result of adopting ASU 2016-02. Amounts that were previously disclosed as "Tenant reimbursements and other income" are now included in "Rental revenue" and are no longer presented as a separate line item. Parking revenues that do not represent components of leases and were previously disclosed as "Rental income" are now included in "Other revenue." Subsequent to January 1, 2019, provisions for credit losses are included in "Rental revenue." Provisions for credit losses prior to January 1, 2019 were disclosed as "Operating expenses" and were not reclassified to conform prior periods to the current presentation.

Noncontrolling Interest [Abstract]

Noncontrolling Interest

Noncontrolling Interest

Noncontrolling interest represents the portion of the OP Units not beneficially owned by the Company. The ownership of an OP Unit and a common share of beneficial interest have essentially the same economic characteristics. Distributions with respect to OP Units will generally mirror distributions with respect to the Company’s common shares. Unitholders (other than the Company) generally have the right, commencing six months from the date of issuance of such OP Units, to cause the Operating Trust to redeem their OP Units in exchange for cash or, at the option of the Company, common shares of the Company on a one-for-one basis. As sole trustee, the Company has the sole discretion to elect whether the redemption right will be satisfied by the Company in cash or the Company’s common shares. As a result, the Noncontrolling interest is classified as permanent equity. As of September 30, 2019, the portion of the Operating Trust not beneficially owned by the Company is in the form of OP Units and LTIP Units (see Note 10 for a description of LTIP Units). LTIP Units may be subject to additional vesting requirements.

The following table presents the changes in Equity Commonwealth’s issued and outstanding common shares and units for the nine months ended September 30, 2019:

	Common Shares	OP Units and LTIP Units	Total
Outstanding at January 1, 2019	121,572,155	45,720	121,617,875
Repurchase of shares	(168,327)	—	(168,327)
Restricted share grants, time-based LTIP Unit grants and vested restricted stock units, net of forfeitures	520,371	2,940	523,311
Outstanding at September 30, 2019	121,924,199	48,660	121,972,859
Noncontrolling ownership interest in the Operating Trust			0.04	%

The carrying value of the Noncontrolling interest is allocated based on the number of OP Units and LTIP Units in proportion to the number of OP Units and LTIP Units plus the number of common shares. We adjust the Noncontrolling interest balance at the end of each period to reflect the noncontrolling partners’ interest in the net assets of the Operating Trust. Net income is allocated to the Noncontrolling interest in the Operating Trust based on the weighted average ownership percentage during the period. Equity Commonwealth’s weighted average ownership interest in the Operating Trust was 99.96% and 99.96% for the three and nine months ended September 30, 2019, respectively.

Fair Value of Assets and Liabilities

Fair Value of Assets and Liabilities

As of September 30, 2019, we do not have any assets or liabilities measured at fair value.

Financial Instruments

Our financial instruments include our cash and cash equivalents, restricted cash, marketable securities, senior unsecured debt and mortgage note payable.  At September 30, 2019 and December 31, 2018, the fair value of these additional financial instruments were not materially different from their carrying values, except as follows (in thousands):

	September 30, 2019				December 31, 2018
	Principal Balance		Fair Value		Principal Balance		Fair Value
Senior unsecured debt and mortgage note payable	$	25,579	$	26,321	$	276,000	$	283,214

The fair values of our senior notes are based on quoted market prices (level 2 inputs), and the fair value of our mortgage note payable is based on estimates using discounted cash flow analyses and currently prevailing interest rates adjusted by credit risk spreads (level 3 inputs).

Other financial instruments that potentially subject us to concentrations of credit risk consist principally of rents receivable. As of September 30, 2019, we have one tenant that is responsible for 23.0% of our total annualized rents, and no other single tenant of ours is responsible for more than 10.0% of our total annualized rents.
