WASHINGTON REAL ESTATE INVESTMENT TRUST AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2017

(UNAUDITED)

NOTE 1:NATURE OF BUSINESS

Washington Real Estate Investment Trust (“Washington REIT”), a Maryland real estate investment trust, is a self-administered equity real estate investment trust, successor to a trust organized in 1960. Our business consists of the ownership and operation of income producing real estate properties in the greater Washington metro region. We own a diversified portfolio of office buildings, multifamily buildings and retail centers.

Federal Income Taxes

We believe that we qualify as a Real Estate Investment Trust (“REIT”) under Sections 856-860 of the Internal Revenue Code and intend to continue to qualify as such. To maintain our status as a REIT, we are, among other things, required to distribute 90% of our REIT taxable income (which is, generally, our ordinary taxable income, with certain modifications), excluding any net capital gains and any deductions for dividends paid to our shareholders on an annual basis. When selling a property, we generally have the option of (a) reinvesting the sales proceeds of property sold, in a way that allows us to defer recognition of some or all taxable gain realized on the sale, (b) distributing gains to the shareholders with no tax to us or (c) treating net long-term capital gains as having been distributed to our shareholders, paying the tax on the gain deemed distributed and allocating the tax paid as a credit to our shareholders.

Generally, and subject to our ongoing qualification as a REIT, no provisions for income taxes are necessary except for taxes on undistributed taxable income and taxes on the income generated by our taxable REIT subsidiaries (“TRSs”). Our TRSs are subject to corporate federal and state income tax on their taxable income at regular statutory rates, or as calculated under the alternative minimum tax, as appropriate. As of September 30, 2017 and December 31, 2016, our TRSs had deferred tax assets of $0.6 million and $0.5 million, respectively, net of valuation allowances of $2.7 million and $2.9 million, respectively. During the 2017 Period (as defined below), we recognized a deferred tax liability of $0.6 million in connection with the acquisition of Watergate 600 (see note 3). As of September 30, 2017 and December 31, 2016, we had net deferred tax liabilities of $1.0 million and $0.4 million, respectively. The deferred tax liabilities are primarily related to temporary differences in the timing of the recognition of revenue, amortization and depreciation.

NOTE 2:SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATIONS

Significant Accounting Policies

We have prepared our consolidated financial statements using the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2016.

Pronouncements Not Yet Adopted

In August 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging:Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update, or alternatively requires adoption for fiscal years beginning after December 15, 2018. This adoption method will require us to recognize the cumulative effect of initially applying the ASU, if any, as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. While we continue to assess all potential impacts of the standard, we do not expect adoption to have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting, which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The new standard is effective for all entities for fiscal years beginning after December 15, 2017 and for interim periods therein. Early adoption is permitted. We do not expect the new standard to have a material impact on our consolidated financial statements.

10

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash,which requires that restricted cash and cash equivalents be included with cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the consolidated statements of cash flows. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein, with early adoption permitted. We are currently evaluating the impact the new standard may have on Washington REIT’s consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments,which provides specific guidance on how cash receipts and payments should be presented and classified in the statement of cash flows for eight specific issues. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein, with early adoption permitted. We are currently evaluating the impact the new standard may have on Washington REIT’s consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments,which requires financial assets measured at an amortized cost basis, including trade receivables, to be presented at the net amount expected to be collected. The new standard is effective for public entities for fiscal years beginning after December 15, 2019 and for interim periods therein with adoption one year earlier permitted. We are currently evaluating the impact the new standard may have on Washington REIT’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”), which amends existing accounting standards for lease accounting, including by requiring lessees to recognize most leases on the balance sheet and making certain changes to lessor accounting. The new standard is effective for public entities for fiscal years beginning after December 15, 2018 and for interim periods therein with early adoption permitted. Upon adoption, for leases in which we are the lessor, the lease contract will be separated into lease and non-lease components in accordance with the provisions outlined within ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The lease component of the contract will be recognized on a straight-line basis in accordance with ASU 2016-02, while the non-lease component will be recognized under the provisions of ASU 2014-09. For lease contracts with a duration of more than one year in which we are the lessee, the present value of future lease payments will be recognized on our balance sheet as a right-of-use asset and a corresponding lease liability. Also, only direct leasing costs may be capitalized under the new standard, while current accounting standards allow for the capitalization of indirect leasing costs. We are currently evaluating the impact ASU 2016-02 may have on Washington REIT’s consolidated financial statements.

In June 2014, the FASB issued ASU 2014-09, which creates a single source of revenue guidance. The new standard provides accounting guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to their customers (unless the contracts are in the scope of other U.S. generally accepted accounting principles (“GAAP”) requirements, such as the leasing literature). The guidance also provides a model for the measurement and recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein. Early adoption is permitted for public entities beginning after December 15, 2016. We intend to adopt the new standard using the modified retrospective method. Upon adoption of ASU 2016-02, the majority of our revenue will be subject to the allocation provisions outlined within the revenue standard. We are currently evaluating the specific implementation requirements for allocating the consideration within our contracts in accordance with ASU 2014-09. We do not expect the new standard to have a material impact on the measurement and recognition of gains and losses on the sale of properties.

Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements include the consolidated accounts of Washington REIT, our majority-owned subsidiaries and entities in which Washington REIT has a controlling interest, including where Washington REIT has been determined to be a primary beneficiary of a variable interest entity (“VIE”). See note 3 for additional information on the property for which there is a noncontrolling interest. All intercompany balances and transactions have been eliminated in consolidation.

We have prepared the accompanying unaudited financial statements pursuant to the rules and regulations of the Securities and Exchange Commission “SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although we believe that the disclosures made are adequate to make the information presented not misleading. In addition, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results for the periods presented have been included. These unaudited financial statements should be read in conjunction with the financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2016.

11

Within these notes to the financial statements, we refer to the three months ended September 30, 2017 and September 30, 2016 as the “2017 Quarter” and the “2016 Quarter,” respectively and the nine months ended September 30, 2017 and September 30, 2016 as the "2017 Period" and "2016 Period," respectively.

Use of Estimates in the Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

NOTE 3:REAL ESTATE

Acquisition

Our current strategy is focused on properties inside the Washington metro region’s Beltway, near major transportation nodes and in areas with strong employment drivers and superior growth demographics. We seek to upgrade our portfolio with acquisitions as appropriate opportunities arise. We acquired the following property during the 2017 Period (the “2017 acquisition”):

Acquisition Date	Property	Type	Net Rentable Square Feet	Contract Purchase Price (In thousands)
April 4, 2017	Watergate 600	Office	293,000	$	135,000

The results of operations from the 2017 acquisition are included in the consolidated statements of income from the acquisition date and are as follows (in thousands):

	Three Months Ended September 30, 2017		Nine Months Ended September 30, 2017
Real estate rental revenue	$	4,831	$	9,733
Net income	356		1,320

We accounted for the acquisition of Watergate 600 as an asset acquisition. Accordingly, we capitalized $2.8 million of costs directly associated with the acquisition. We measured the value of the acquired physical assets (land and building), in-place leases (tenant origination costs, leasing commissions, absorption costs and lease intangible assets/liabilities), and any other liabilities by allocating the total cost of the acquisition on a relative fair value basis.

We have recorded the total cost of the 2017 acquisition as follows (in thousands):

Land	$	45,981
Building	66,241
Tenant origination costs	12,084
Leasing commissions/absorption costs	23,161
Lease intangible assets	498
Lease intangible liabilities	(9,585		)
Deferred tax liability	(560		)
Total	$	137,820

The weighted remaining average life for the 2017 acquisition components above, other than land, building and deferred tax liability, are 92 months for tenant origination costs, 85 months for leasing commissions/absorption costs, 16 months for net lease intangible assets and 105 months for net lease intangible liabilities.

The difference in the total contract purchase price of $135.0 million for the 2017 acquisition and cash paid for the acquisition per the consolidated statements of cash flows of $138.4 million is primarily due to capitalized acquisition-related costs ($2.8 million) and a net credit to the buyer for certain expenditures ($1.0 million), partially offset by the issuance of 12,124 operating partnership units (“Operating Partnership Units”) as part of the consideration ($0.4 million). The Operating Partnership Units are units in WashREIT Watergate 600 OP LP, a consolidated subsidiary of Washington REIT. These Operating Partnership Units may be

12

redeemed for either cash equal to the fair market value of a share of Washington REIT common stock at the time of redemption (based on a 20-day average price) or, at the option of Washington REIT, one registered or unregistered share of Washington REIT common stock. In connection with the 2017 acquisition, we granted registration rights to the two contributors of the Watergate 600 property relating to the resale of any shares issued upon exchange of Operating Partnership Units pursuant to a shelf registration statement that we have an obligation to make available to the contributors approximately one year after the issuance of the Operating Partnership Units.

Development/Redevelopment

We have properties under development/redevelopment and held for current or future development as of September 30, 2017. In the office segment, we have a redevelopment project at the Army Navy Building, an office property in Washington, DC, to upgrade its common areas and add significant amenities in order to make the property more competitive within its sub-market. As of September 30, 2017, we had invested $4.4 million in the redevelopment and have placed $4.3 million of the project into service. We have substantially completed the additional amenities and common areas and expect to place 11th floor common areas into service by the end of 2017.

In the multifamily segment, we have The Trove, a multifamily development adjacent to The Wellington, and own land held for future multifamily development adjacent to Riverside Apartments. As of September 30, 2017, we had invested $27.3 million and $19.0 million, including the costs of acquired land, in The Trove and the development adjacent to Riverside Apartments, respectively.

In the retail segment, we currently have a redevelopment project to add rentable space at Spring Valley Village. As of September 30, 2017, we had invested $2.5 million in the redevelopment.

Variable Interest Entity

In June 2011, we executed a joint venture operating agreement with a real estate development company to develop The Maxwell, a mid-rise multifamily property at 650 North Glebe Road in Arlington, Virginia. Major construction activities at The Maxwell ended during December 2014, and the building became available for occupancy during the first quarter of 2015. Washington REIT was the 90% owner of the joint venture. The real estate development company owned 10% of the joint venture and was responsible for the development and construction of the property. Subsequent to the end of the 2017 Quarter, we purchased the remaining 10% of the joint venture from the real estate development company for a contract purchase price of $4.1 million. Upon the completion of this transaction, the joint venture was dissolved and Washington REIT became sole owner of The Maxwell.

We determined that, prior to completion of this transaction, The Maxwell joint venture was a VIE primarily based on the fact that the equity investment at risk was not sufficient to permit the entity to finance its activities without additional financial support. We also determined that Washington REIT was the primary beneficiary of the VIE due to the fact that Washington REIT was determined to have a controlling financial interest in the entity. In January 2016, Washington REIT exercised its right to purchase at par The Maxwell’s construction loan from the original third-party lender. Upon the purchase, the construction loan became an intercompany loan payable from the consolidated VIE to Washington REIT that is eliminated in consolidation. Subsequent to the 2017 Quarter, the intercompany loan payable was extinguished as part of the Washington REIT’s purchase of the joint venture partner’s 10%interest.

As of September 30, 2017 and December 31, 2016, The Maxwell’s assets were as follows (in thousands):

	September 30, 2017			December 31, 2016
Land	$	12,851		$	12,851
Income producing property	37,960			37,949
Accumulated depreciation and amortization	(6,255		)	(4,571		)
Other assets	1,016			456
	$	45,572		$	46,685

As of September 30, 2017 and December 31, 2016, The Maxwell’s liabilities were as follows (in thousands):

	September 30, 2017		December 31, 2016
Mortgage notes payable (1)	$	31,580	$	31,869
Accounts payable and other liabilities	395		186
Tenant security deposits	94		99
	$	32,069	$	32,154

⁽¹⁾ The mortgage notes payable balances as of September 30, 2017 and December 31, 2016 are eliminated in consolidation due to the purchase of the loan by Washington REIT in January 2016.

Properties Sold and Held for Sale

We intend to hold our properties for investment with a view to long-term appreciation, to engage in the business of acquiring, developing and owning our properties, and to make occasional sales of the properties that no longer meet our long-term strategy or return objectives and where market conditions for sale are favorable. The proceeds from the sales may be reinvested into other properties, used to fund development operations or to support other corporate needs, or distributed to our shareholders. Depreciation on these properties is discontinued when classified as held for sale, but operating revenues, other operating expenses and interest continue to be recognized until the date of sale.

During the 2017 Quarter, we entered into negotiations to sell Braddock Metro Center, a 356,000 square foot office property in Alexandria, Virginia. Subsequent to the 2017 Quarter, we executed a letter of intent with a potential buyer for the property and are in the process of negotiating a purchase and sale agreement. Due to the negotiations to sell the property, we evaluated Braddock Metro Center for impairment. We recognized a $5.0 million impairment charge for the 2017 Quarter in order to reduce the carrying value of the property to its estimated fair value. We based this fair valuation on the expected net proceeds from a potential sale. There are few observable market transactions for similar properties. This fair valuation falls into Level 2 of the fair value hierarchy due to its reliance on a quoted price in a market that is not active. Braddock Metro Center does not meet the criteria for classification as held for sale as of September 30, 2017.

During the second quarter of 2017, we executed a purchase and sale agreement for the sale of Walker House Apartments, a multifamily property in Gaithersburg, Maryland, for a contract sale price of $32.2 million. We determined that the property met the criteria for classification as held for sale as of June 30, 2017, and the property continues to meet the criteria for classification as held for sale as of September 30, 2017. We closed on the sale on October 23, 2017.

We sold the following properties in 2016:

Disposition Date	Property Name	Segment	Number of Units/ Rentable Square Feet	Contract Sales  Price (in thousands)		Gain on Sale (in thousands)
May 26, 2016	Dulles Station II (1)	Office	N/A	$	12,100	$	527

September 22, 2016	Maryland Office Portfolio Transaction II (3)	Office	491,000	128,500		77,592
	Total 2016		1,183,000	$	252,100	$	101,704

⁽¹⁾  Land held for future development and an interest in a parking garage.

⁽²⁾  Maryland Office Portfolio Transaction I consists of 6110 Executive Boulevard, 600 Jefferson Plaza, Wayne Plaza and West Gude Drive.

⁽³⁾  Maryland Office Portfolio Transaction II consists of 51 Monroe Street and One Central Plaza.

While the sale of the Maryland Office Portfolio, in the aggregate, constituted an individually significant disposition, the Maryland Office Portfolio does not qualify for presentation and disclosure as a discontinued operation as it does not represent a strategic shift in our operations. Real estate rental revenue and net income for the Maryland Office Portfolio for the three and nine months endedSeptember 30, 2017 and 2016 are as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2017		2016		2017		2016
Real estate rental revenue	$	—	$	3,689	$	—	$	20,266
Net income	—		2,474		—		9,376

We do not have significant continuing involvement in the operations of the disposed properties.

NOTE 4:MORTGAGE NOTES PAYABLE

In February 2017, we prepaid without penalty the remaining $49.6 million of the mortgage note secured by the Army Navy Building.

NOTE 5:UNSECURED LINES OF CREDIT PAYABLE

We have a $600.0 million unsecured revolving credit agreement (“Revolving Credit Facility”) that matures in June 2019, unless extended pursuant to one or both of the twosix months extension options. The Revolving Credit Facility has an accordion feature, which we utilized a portion of in September 2015, as described below, that allows us to increase the facility to $1.0 billion, subject to the extent the lenders agree to provide additional revolving loan commitments or term loans. In September 2015, we entered into a $150.0 million unsecured term loan (“2015 Term Loan”) by executing a portion of the accordion feature under the Revolving Credit Facility. The 2015 Term Loan has a 5.5 year term and currently has an interest rate of one month LIBOR plus 110 basis points, based on Washington REIT’s current unsecured debt ratings. We entered into two interest rate swaps to effectively fix the interest rate at 2.7% (see note 7).

The Revolving Credit Facility bears interest at a rate of either one month LIBOR plus a margin ranging from 0.875% to 1.55% or the base rate plus a margin ranging from 0.0% to 0.55% (in each case depending upon Washington REIT’s credit rating). The base rate is the highest of the administrative agent’s prime rate, the federal funds rate plus 0.50% and the LIBOR market index rate plus 1.0%. In addition, the Revolving Credit Facility requires the payment of a facility fee ranging from 0.125% to 0.30% (depending on Washington REIT’s credit rating) on the $600.0 million committed capacity, without regard to usage. As of September 30, 2017, the interest rate on the facility is one month LIBOR plus 1.00% and the facility fee is 0.20%.

The amount of the Revolving Credit Facility’s unsecured line of credit unused and available at September 30, 2017 is as follows (in thousands):

Committed capacity	$	600,000
Borrowings outstanding	(189,000		)
Unused and available	$	411,000

We executed borrowings and repayments on the Revolving Credit Facility during the 2017 Period as follows (in thousands):

	Revolving Credit Facility
Balance at December 31, 2016	$	120,000
Borrowings	259,000
Repayments	(190,000		)
Balance at September 30, 2017	$	189,000

NOTE 6:NOTES PAYABLE

During 2016, we entered into a seven year, $150.0 million unsecured term loan (“2016 Term Loan”) maturing on July 21, 2023 with a deferred draw period of up to six months commencing on July 22, 2016. The 2016 Term Loan bears interest at a rate of either LIBOR plus a margin ranging from 1.50% to 2.45% or the base rate plus a margin ranging from 0.5% to 1.45% (in each case depending upon Washington REIT’s credit rating). The base rate is the highest of the administrative agent’s prime rate, the federal funds rate plus 0.50% and one-month LIBOR plus 1.0%. The 2016 Term Loan currently has an interest rate of one month LIBOR plus 165 basis points, based on Washington REIT’s current unsecured debt ratings. We borrowed $100.0 million on the term loan in the fourth quarter of 2016, and borrowed the remaining $50.0 million during the first quarter of 2017. We have also previously entered into forward interest rate swaps commencing on March 31, 2017 to effectively fix the interest rate on the 2016 Term Loan at 2.9% (see note 7).

NOTE 7:DERIVATIVE INSTRUMENTS

On September 15, 2015, we entered into two interest rate swap arrangements with a total notional amount of $150.0 million to swap the floating interest rate under the 2015 Term Loan (see note 5) to an all-in fixed interest rate of 2.7% starting on October 15, 2015 and extending until the maturity of the 2015 Term Loan on March 15, 2021. On July 22, 2016, we entered into two forward interest rate swap arrangements with a total notional amount of $150.0 million to swap the floating interest rate under the 2016

15

Term Loan (see note 6) to an all-in fixed interest rate of 2.9% starting on March 31, 2017 and extending until the maturity of the 2016 Term Loan on July 21, 2023.

The interest rate swaps qualify as cash flow hedges and are recorded at fair value in accordance with GAAP, based on discounted cash flow methodologies and observable inputs. We record the effective portion of changes in fair value of the cash flow hedges in other comprehensive income. The resulting unrealized gain (loss) on the effective portions of the cash flow hedges was the only activity in other comprehensive income during the periods presented in our consolidated financial statements. We assess the effectiveness of our cash flow hedges both at inception and on an ongoing basis. The cash flow hedges were effective for the 2017 Quarter and 2017 Period and 2016 Quarter and 2016 Period, and therefore hedge ineffectiveness did not impact earnings during the 2017 Quarter and 2017 Period and 2016 Quarter and 2016 Period.

The fair values of the interest rate swaps as of September 30, 2017 and December 31, 2016, are as follows (in thousands):

					Fair Value
					Asset Derivatives
Derivative Instrument	Aggregate Notional Amount		Effective Date	Maturity Date	September 30, 2017		December 31, 2016
Interest rate swaps	$	150,000	October 15, 2015	March 15, 2021	$	747	$	417
Interest rate swaps	150,000		March 31, 2017	July 21, 2023	6,101		7,194
	$	300,000			$	6,848	$	7,611

We record interest rate swaps on our consolidated balance sheets with prepaid expenses and other assets when in a net asset position and with accounts payable and other liabilities when in a net liability position. The interest rate swaps have been effective since inception. The net gains or losses on the effective swaps are recognized in other comprehensive income, as follows (in thousands):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2017			2016		2017			2016
Unrealized (loss) gain on interest rate hedges	$	(9	)	$	739	$	(763	)	$	(4,320	)

Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the next twelve months, we estimate that an additional $0.1 million will be reclassified as decrease to interest expense.

We have agreements with each of our derivative counterparties that contain a provision whereby we could be declared in default on our derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness. As of September 30, 2017, the fair value of derivatives is in a net asset position of $6.8 million, which includes accrued interest but excludes any adjustment for nonperformance risk. As of September 30, 2017, we have not posted any collateral related to these agreements.

Derivative instruments expose us to credit risk in the event of non-performance by the counterparty under the terms of the interest rate hedge agreement. We believe that we minimize our credit risk on these transactions by dealing with major, creditworthy financial institutions. We monitor the credit ratings of counterparties and our exposure to any single entity, thus minimizing our credit risk concentration.

NOTE 8:FAIR VALUE DISCLOSURES

Assets and Liabilities Measured at Fair Value

For assets and liabilities measured at fair value on a recurring basis, quantitative disclosures about the fair value measurements are required to be disclosed separately for each major category of assets and liabilities, as follows:

Level 1: Quoted prices in active markets for identical assets

Level 2: Significant other observable inputs

Level 3: Significant unobservable inputs

The only assets or liabilities we had at September 30, 2017 and December 31, 2016 that are recorded at fair value on a recurring basis are the assets held in the Supplemental Executive Retirement Plan (“SERP”), which primarily consist of investments in mutual funds, and the interest rate swaps (see note 7).

16

We base the valuations related to the SERP on assumptions derived from significant other observable inputs and accordingly these valuations fall into Level 2 in the fair value hierarchy.

The valuation of the interest rate swaps is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each interest rate swap. This analysis reflects the contractual terms of the interest rate swaps, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with the provisions of ASC 820, we incorporate credit valuation adjustments in the fair value measurements to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk. These credit valuation adjustments were concluded to not be significant inputs for the fair value calculations for the periods presented. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as the posting of collateral, thresholds, mutual puts and guarantees. The valuation of interest rate swaps fall into Level 2 in the fair value hierarchy.

The fair values of these assets and liabilities at September 30, 2017 and December 31, 2016 were as follows (in thousands):

	September 30, 2017								December 31, 2016
	Fair Value		Level 1		Level 2		Level 3		Fair Value		Level 1		Level 2		Level 3
Assets:
SERP	$	1,727	$	—	$	1,727	$	—	$	1,407	$	—	$	1,407	$	—
Interest rate swaps	6,848		—		6,848		—		7,611		—		7,611		—

Financial Assets and Liabilities Not Measured at Fair Value

The following disclosures of estimated fair value were determined by management using available market information and established valuation methodologies, including discounted cash flow. Many of these estimates involve significant judgment. The estimated fair value disclosed may not necessarily be indicative of the amounts we could realize on disposition of the financial instruments. The use of different market assumptions or estimation methodologies could have an effect on the estimated fair value amounts. In addition, fair value estimates are made at a point in time and thus, estimates of fair value subsequent to September 30, 2017 may differ significantly from the amounts presented.

Following is a summary of significant methodologies used in estimating fair values and a schedule of fair values at September 30, 2017 and December 31, 2016.

Cash and Cash Equivalents and Restricted Cash

Cash and cash equivalents and restricted cash include cash and commercial paper with original maturities of less than 90 days, which are valued at the carrying value, which approximates fair value due to the short maturity of these instruments (Level 1 inputs).

Notes Receivable

We acquired a note receivable (“2445 M Street note”) in 2008 with the purchase of 2445 M Street. We estimate the fair value of the 2445 M Street note based on a discounted cash flow methodology using market discount rates (Level 3 inputs).

Debt

Mortgage notes payable consist of instruments in which certain of our real estate assets are used for collateral. We estimate the fair value of the mortgage notes payable by discounting the contractual cash flows at a rate equal to the relevant treasury rates (with respect to the timing of each cash flow) plus credit spreads estimated through independent comparisons to real estate assets or loans with similar characteristics. Lines of credit payable consist of our bank facility which we use for various purposes including working capital, acquisition funding and capital improvements. The lines of credit advances and term loans with floating interest rates are priced at a specified rate plus a spread. We estimate the market value based on a comparison of the spreads of the advances to market given the adjustable base rate. We estimate the fair value of the notes payable by discounting the contractual cash flows

17

at a rate equal to the relevant treasury rates (with respect to the timing of each cash flow) plus credit spreads derived using the relevant securities’ market prices. We classify these fair value measurements as Level 3 as we use significant unobservable inputs and management judgment due to the absence of quoted market prices.

As of September 30, 2017 and December 31, 2016, the carrying values and estimated fair values of our financial instruments were as follows (in thousands):

	September 30, 2017				December 31, 2016
	Carrying Value		Fair Value		Carrying Value		Fair Value
Cash and cash equivalents	$	11,326	$	11,326	$	11,305	$	11,305
Restricted cash	1,442		1,442		6,317		6,317
2445 M Street note receivable	2,005		2,194		2,089		2,173
Mortgage notes payable, net	96,045		98,892		148,540		149,997
Lines of credit	189,000		189,000		120,000		120,000
Notes payable, net	894,103		932,766		843,084		873,516

NOTE 9:STOCK BASED COMPENSATION

Washington REIT maintains short-term (“STIP”) and long-term (“LTIP”) incentive plans that allow for stock based awards to officers and non-officer employees. Stock based awards are provided to officers and non-officer employees, as well as trustees, under the Washington Real Estate Investment Trust 2016 Omnibus Incentive Plan which allows for awards in the form of restricted shares, restricted share units, options and other awards up to an aggregate of 2,400,000 shares over the ten-year period in which the plan will be in effect. Restricted share units are converted into shares of our stock upon full vesting through the issuance of new shares.

Total Compensation Expense

Total compensation expense recognized in the consolidated financial statements for all outstanding share based awards was $1.2 million and $0.3 million for the 2017 Quarter and 2016 Quarter, respectively, and $3.6 million and $2.7 million for the 2017 Period and 2016 Period, respectively.

Restricted Share Awards

The total fair values of restricted share awards vested was $2.0 million and $2.5 million for the 2017 Period and 2016 Period, respectively.

The total unvested restricted share awards at September 30, 2017 was 355,120 shares, which had a weighted average grant date fair value of $30.86 per share. As of September 30, 2017, the total compensation cost related to unvested restricted share awards was $7.4 million, which we expect to recognize over a weighted average period of 37 months.

NOTE 10:EARNINGS PER COMMON SHARE

We determine “Basic earnings per share” using the two-class method as our unvested restricted share awards and units have non-forfeitable rights to dividends, and are therefore considered participating securities. We compute basic earnings per share by dividing net income attributable to the controlling interest less the allocation of undistributed earnings to unvested restricted share awards and units by the weighted-average number of common shares outstanding for the period.

We also determine “Diluted earnings per share” as the more dilutive of the two-class method or the treasury stock method with respect to the unvested restricted share awards. We further evaluate any other potentially dilutive securities at the end of the period and adjust the basic earnings per share calculation for the impact of those securities that are dilutive. Our diluted earnings per share calculation includes the dilutive impact of our share based awards with performance conditions prior to the grant date and awards with market conditions under the contingently issuable method. The dilutive earnings per share calculation also considers the Operating Partnership Units issued in connection with the 2017 acquisition, which were not dilutive for any of the periods presented.

The computations of basic and diluted earnings per share for the three and nine months ended September 30, 2017 and 2016 were as follows (in thousands, except per share data):

NOTE 11:SEGMENT INFORMATION

We have three reportable segments: office, multifamily and retail. Office properties provide office space for various types of businesses and professions. Multifamily properties provide rental housing for individuals and families throughout the greater Washington metro region. Retail properties are typically grocery store-anchored neighborhood centers that include other small shop tenants or regional power centers with several junior box tenants.

We evaluate performance based upon net operating income from the combined properties in each segment. Our reportable operating segments are consolidations of similar properties. GAAP requires that segment disclosures present the measure(s) used by the chief operating decision maker for purposes of assessing segments’ performance. Net operating income is a key measurement of our segment profit and loss. Net operating income is defined as segment real estate rental revenue less segment real estate expenses.

19

The following tables present revenues, net operating income, capital expenditures and total assets for the three and nine months ended September 30, 2017 and 2016 from these segments, and reconcile net operating income of reportable segments to net income attributable to the controlling interests as reported (in thousands):

NOTE 12:SHAREHOLDERS' EQUITY

On June 23, 2015, we entered into four separate equity distribution agreements (collectively, the “Equity Distribution Agreements”) with each of Wells Fargo Securities, LLC, BNY Mellon Capital Markets, LLC, Citigroup Global Markets Inc. and RBC Capital Markets, LLC relating to the issuance of up to $200.0 million of our common shares from time to time. Issuances of our common shares are made at market prices prevailing at the time of issuance. We may use net proceeds from the issuance of common shares under this program for general corporate purposes, including, without limitation, working capital, the acquisition, renovation, expansion, improvement, development or redevelopment of income producing properties or the repayment of debt. During the 2017 Quarter, we issued 1.5 million common shares under the Equity Distribution Agreements at an average price of $32.89 per share, raising $49.3 million in net proceeds. During the 2017 Period, we issued 3.6 million common shares under the Equity Distribution Agreements at an average price of $32.06 per share, raising $113.2 million in net proceeds.

We have a dividend reinvestment program, whereby shareholders may use their dividends and optional cash payments to purchase common shares. The common shares sold under this program may either be common shares issued by us or common shares

21

purchased in the open market. During the 2017 Quarter, we issued 20,884 common shares under this program at a weighted average price of $32.79 per share, raising $0.7 million in net proceeds. During the 2017 Period, we issued 0.1 million common shares under the dividend reinvestment program at a weighted average price of $32.24 per share, raising $2.5 million in net proceeds.

General

Introductory Matters

We provide our Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) in addition to the accompanying consolidated financial statements and notes to assist readers in understanding our results of operations and financial condition. We organize the MD&A as follows:

• Overview. Discussion of our business outlook, operating results, investment activity, financing activity and capital requirements to provide context for the remainder of MD&A.

• Results of Operations. Discussion of our financial results comparing the 2017 Quarter to the 2016 Quarter and the 2017 Period to the 2016 Period.

• Liquidity and Capital Resources. Discussion of our financial condition and analysis of changes in our capital structure and cash flows.

• Funds From Operations. Calculation of NAREIT Funds From Operations (“NAREIT FFO”), a non-GAAP supplemental measure to net income.

• Critical Accounting Policies and Estimates. Descriptions of accounting policies that reflect significant judgments and estimates used in the preparation of our consolidated financial statements.

When evaluating our financial condition and operating performance, we focus on the following financial and non-financial indicators:

• Net operating income (“NOI”), calculated as real estate rental revenue less real estate expenses, is a non-GAAP measure. NOI is calculated as net income, less non-real estate revenue and the results of discontinued operations (including the gain on sale, if any), plus interest expense, depreciation and amortization, general and administrative expenses, acquisition costs, real estate impairment and gain or loss on extinguishment of debt.

• NAREIT FFO, calculated as set forth below under the caption “Funds from Operations.”

• Ending occupancy, calculated as occupied square footage as a percentage of total square footage as of the last day of that period.

23

• Leased percentage, calculated as the percentage of available physical net rentable area leased for our office and retail segments and percentage of apartments leased for our multifamily segment.

• Rental rates.

• Leasing activity, including new leases, renewals and expirations.

For purposes of evaluating comparative operating performance, we categorize our properties as “same-store”, “non-same-store” or discontinued operations.A “same-store” property is one that was owned for the entirety of 2017 and the prior year, and excludes properties under redevelopment or development and properties purchased or sold at any time during 2017 or the prior year. A “non-same-store” property is one that was acquired, under redevelopment or development, or placed into service during 2017 or the prior year. We define redevelopment properties as those for which we expect to spend significant development and construction costs on existing or acquired buildings pursuant to a formal plan which has a current impact on operating results, occupancy and the ability to lease space with the intended result of a higher economic return on the property. Properties under redevelopment or development are included with the non-same-store properties beginning in the period during which redevelopment or development activities commence. We consider properties to no longer be under redevelopment or development upon substantial completion of redevelopment or development activities, and the earlier of achieving 90% occupancy or two years after substantial completion.

Overview

Business Outlook

Our revenues are derived primarily from the ownership and operation of income producing properties in the greater Washington metro region. As of September 30, 2017, we owned a diversified portfolio of 50 properties, totaling approximately 6.4 million square feet of commercial space and 4,480 multifamily units, and land held for development. These 50 properties consisted of 20 office properties, 16 retail centers and 14 multifamily properties. On October 23, 2017, we sold Walker House Apartments, a 212-unit multifamily property in Gaithersburg, Maryland, for a contract sale price of $32.2 million.

Operating Results

Net income attributable to the controlling interests, NOI and NAREIT FFO for the three months ended September 30, 2017 and 2016 were as follows (in thousands):

	Three Months Ended September 30,
	2017		2016		$ Change			% Change
Net income attributable to the controlling interests	$	2,833	$	79,674	$	(76,841	)	(96.4	)%
NOI (1)	$	53,173	$	50,606	$	2,567		5.1	%
NAREIT FFO (2)	$	35,754	$	32,975	$	2,779		8.4	%
(1) See page 26 of the MD&A for a reconciliation of NOI to net income.
(2) See page 35 of the MD&A for a reconciliation of NAREIT FFO to net income.

The lower net income attributable to the controlling interests is primarily due to gains on sale of real estate during the 2016 Quarter ($77.6 million), a real estate impairment charge during the 2017 Quarter ($5.0 million) and higher general and administrative expenses ($0.8 million), partially offset by lower depreciation and amortization expenses ($3.0 million), higher NOI ($2.6 million) and lower interest expense ($1.0 million).

The increase in NOI is primarily due to the Watergate 600 acquisition ($3.3 million) and higher NOI from same-store properties ($1.1 million) and Army Navy Building ($0.2 million), which substantially completed redevelopment activities during the 2017 Quarter. These were partially offset by the property sales during 2016 ($2.5 million). The higher same-store NOI is explained in further detail beginning on page 26 (Results of Operations - 2017 Quarter Compared to 2016 Quarter). Same-store ending occupancy increased to 93.8% as of September 30, 2017, from 93.6% one year ago, primarily due to higher occupancy in the office segment.

The higher NAREIT FFO is primarily attributable to the higher NOI ($2.6 million) and lower interest expense ($1.0 million), partially offset by higher general and administrative expenses ($0.8 million).

24

Investment Activity

Significant investment transactions during the 2017 Period included the following:

• The acquisition of Watergate 600, which we refer to as the 2017 acquisition, a 293,000 net rentable square foot office building in Washington, DC, for a contract purchase price of $135.0 million in a transaction that was structured to include the issuance of 12,124 operating partnership units in WashREIT Watergate 600 OP LP, a consolidated subsidiary of Washington REIT (“Operating Partnership Units”), representing $0.4 million of the purchase price. We incurred $2.8 million of acquisition costs related to this transaction.

Financing Activity

Significant financing transactions during the 2017 Period included the following:

• The prepayment at par of the remaining $49.6 million of the mortgage note secured by the Army Navy Building in February 2017.

• The draw of the remaining $50.0 million on the seven year, $150 million unsecured term loan agreement maturing on July 21, 2023. We used the borrowing to refinance maturing secured debt.

• The issuance of approximately 3.6 million common shares under our ATM program at an average price to the public of $32.06 per share, for net proceeds of approximately $113.2 million.

As of September 30, 2017, the interest rate on the Revolving Credit Facility was one month LIBOR plus 1.00% and the facility fee was 0.20%. As of October 26, 2017, our Revolving Credit Facility has a borrowing capacity of $431.0 million.

Capital Requirements

We do not have any other debt maturities during 2017. We expect to have additional capital requirements as set forth on page 32 (Liquidity and Capital Resources - Capital Requirements).

Results of Operations

The discussion that follows is based on our consolidated results of operations for the 2017 Quarter and 2017 Period and 2016 Quarter and 2016 Period. The ability to compare one period to another is significantly affected by acquisitions completed and dispositions made during 2016 and 2017 (see note 3 to the consolidated financial statements).

Net Operating Income

NOI is a non-GAAP measure defined as net income, less non-real estate revenue and the results of discontinued operations (including the gain on sale, if any), plus interest expense, depreciation and amortization, general and administrative expenses, acquisition costs, real estate impairment and gain or loss on extinguishment of debt. NOI is the primary performance measure we use to assess the results of our operations at the property level. We believe that NOI is useful as a performance measure because, when compared across periods, NOI reflects the impact on operations of trends in occupancy rates, rental rates and operating costs on an unleveraged basis, providing perspective not immediately apparent from net income. NOI excludes certain components from net income in order to provide results more closely related to a property’s results of operations. For example, interest expense is not necessarily linked to the operating performance of a real estate asset. In addition, depreciation and amortization, because of historical cost accounting and useful life estimates, may distort operating performance at the property level. As a result of the foregoing, we provide NOI as a supplement to net income, calculated in accordance with GAAP. NOI does not represent net income or income from continuing operations, in either case calculated in accordance with GAAP. As such, it should not be considered an alternative to these measures as an indication of our operating performance. A reconciliation of NOI to net income follows.

25

2017 Quarter Compared to 2016 Quarter

The following tables reconcile NOI to net income (loss) attributable to the controlling interests and provide the basis for our discussion of our consolidated results of operations and NOI in the 2017 Quarter compared to the 2016 Quarter. All amounts are in thousands, except percentage amounts.

Real Estate Rental Revenue

Real estate rental revenue is comprised of (a) minimum base rent, which includes rental revenues recognized on a straight-line basis, (b) revenue from the recovery of operating expenses from our tenants, (c) provisions for doubtful accounts in the same quarter that we established the receivable, which include provisions for straight-line receivables, (d) revenue from the collection of lease termination fees and (e) parking and other tenant charges such as percentage rents.

Real estate rental revenue for same-store properties for the three months ended September 30,2017 and 2016 was as follows (in thousands):

	Three Months Ended September 30,
	2017			2016			$ Change			% Change
Minimum base rent	$	57,940		$	56,154		$	1,786		3.2	%

Total same-store real estate rental revenue	$	68,230		$	66,788		$	1,442		2.2	%

• Minimum base rent: Increase primarily due to higher rental income ($2.0 million), partially offset by higher rent abatements ($0.3 million).

• Recoveries from tenants: Decrease primarily due to lower reimbursements for real estate taxes ($0.2 million) and operating expenses ($0.1 million).

• Provision for doubtful accounts: Increase primarily due to higher provisions in the retail segment.

26

• Lease termination fees: Decrease primarily due to lower fees in the office segment ($0.4 million), partially offset by higher fees in the retail segment ($0.2 million).

• Parking and other tenant charges: Increase primarily due to higher parking income ($0.2 million), primarily in the office segment.

Real estate rental revenue from same-store properties by segment was as follows (in thousands):

	Three Months Ended September 30,
	2017		2016		$ Change		% Change
Office	$	34,026	$	33,071	$	955	2.9	%
Multifamily	18,600		18,313		287		1.6	%
Retail	15,604		15,404		200		1.3	%
Total same-store real estate rental revenue	$	68,230	$	66,788	$	1,442	2.2	%

• Office: Increase primarily due to higher rental ($1.7 million) and parking ($0.1 million) income, partially offset by higher rent abatements ($0.4 million) and lower lease termination fees ($0.4 million).

• Multifamily: Increase primarily due to higher rental income ($0.3 million).

• Retail: Increase primarily due to higher lease termination fees ($0.2 million).

Real estate rental revenue from acquisitions increased due to the acquisition of Watergate 600 ($4.8 million) in the second quarter of 2017 and higher rental income at Riverside Apartments ($0.2 million).

Real estate rental revenue from development/redevelopment properties increased primarily due to higher rental income ($0.4 million) at Army Navy Building, which substantially completed redevelopment activities during the 2017 Quarter.

Ending occupancy represents occupied square footage indicated as a percentage of total square footage as of the last day of that period. Ending occupancy by segment for the 2017 Quarter and 2016 Quarter was as follows:

	September 30, 2017						September 30, 2016						Increase (decrease)
Segment	Same-Store		Non-Same-Store		Total		Same-Store		Non-Same-Store		Total		Same-Store		Non-Same-Store		Total
Office	93.4	%	92.5	%	93.2	%	91.0	%	86.4	%	90.5	%	2.4	%	6.1	%	2.7	%

Total	93.8	%	93.7	%	93.8	%	93.6	%	90.5	%	93.2	%	0.2	%	3.2	%	0.6	%

• Office: The increase in same-store ending occupancy was primarily due to higher ending occupancy at Silverline Center and 1776 G Street, partially offset by lower ending occupancy at Quantico Corporate Center.

• Multifamily: The decrease in same-store ending occupancy was primarily due to lower ending occupancy at 3801 Connecticut Avenue and The Kenmore.

• Retail: The decrease in same-store ending occupancy was primarily due to lower ending occupancy at Frederick Crossing and Concord Center, partially offset by higher ending occupancy at Randolph Shopping Center.

During the 2017 Quarter, we executed new and renewal leases in our office and retail segments as follows:

	Square Feet (in thousands)	Average Rental Rate (per square foot)		% Rental Rate Increase (Decrease)		Leasing Costs (1) (per square foot)		Free Rent (weighted average months)	Retention Rate
Office	56	$	60.34	19.6	%	$	94.11	6.3	6.8	%
Retail	48	27.87		5.0	%	7.47		0.4	95.8	%
Total	104	45.38		15.0	%	54.18		4.5	27.1	%

⁽¹⁾ Consists of tenant improvements and leasing commissions.

The low retention rate in the office segment is primarily due to the non-renewal of a large tenant at Braddock Metro Center. We have executed a lease with a new tenant for that space, with the lease expected to commence in 2018.

27

Real Estate Expenses

Real estate expenses as a percentage of revenue for the 2017 Quarter and 2016 Quarter were 35.8% and 36.6%, respectively.

Real estate expenses from same-store properties by segment were as follows (in thousands):

	Three Months Ended September 30,
	2017		2016		$ Change		% Change
Office	$	13,057	$	12,860	$	197	1.5	%
Multifamily	7,451		7,443		8		0.1	%
Retail	3,687		3,570		117		3.3	%
Total same-store real estate expenses	$	24,195	$	23,873	$	322	1.3	%

• Office: Increase primarily due to higher real estate tax ($0.1 million) and custodial ($0.1 million) expenses.

• Multifamily: Increase primarily due to higher real estate taxes ($0.1 million), partially offset by lower utilities expenses ($0.1 million).

• Retail: Increase primarily due to higher real estate tax expense ($0.1 million).

Other Income and Expenses

Depreciation and Amortization: Decrease primarily due to lower amortization of acquired lease assets at Riverside Apartments ($4.6 million) and lower depreciation and amortization at same-store properties ($1.1 million), partially offset by the Watergate 600 acquisition ($2.6 million). The lower same-store depreciation and amortization is primarily due to lower amortization of leasing commissions and acquired intangible lease assets.

General and administrative expenses: Increase primarily due to higher share-based compensation ($0.9 million) primarily due to a higher volume of forfeitures during the 2016 Quarter.

Real estate impairment: Impairment charge during the 2017 Quarter to write down the carrying value of Braddock Metro Center to its estimated fair value (see note 3 to the consolidated financial statements).

Gain on sale of real estate: Decrease due to completion of the sales of 51 Monroe Street and One Central Plaza during the 2016 Quarter.

Interest Expense: Interest expense by debt type for the three months ended September 30,2017 and 2016 was as follows (in thousands):

	Three Months Ended September 30,
Debt Type	2017			2016			$ Change			% Change
Notes payable	$	9,446		$	8,364		$	1,082		12.9	%
Mortgage notes payable	1,163			3,419			(2,256		)	(66.0	)%
Lines of credit	1,798			1,578			220			13.9	%
Capitalized interest	(231		)	(188		)	(43		)	22.9	%
Total	$	12,176		$	13,173		$	(997	)	(7.6	)%

• Notes payable: Increase primarily due to executing the $150.0 million term loan in 2016, which has a floating interest rate effectively fixed at 2.9% by interest rate swaps. We borrowed $100.0 million on the term loan in the fourth quarter of 2016, and borrowed the remaining $50.0 million during the first quarter of 2017.

• Mortgage notes payable: Decrease primarily due to the repayment of the mortgage notes secured by John Marshall II, 3801 Connecticut Avenue, Bethesda Hill Apartments, Walker House Apartments, 2445 M Street and the Army Navy Building in 2017 and 2016.

• Lines of credit: Increase primarily due to a weighted average interest rate of 2.3% during the 2017 Quarter, as compared to 1.5% during the 2016 Quarter.

• Capitalized interest: Increase primarily due to capitalization of interest on spending related to the Trove, the multifamily development adjacent to The Wellington.

Real Estate Rental Revenue

Real estate rental revenue is comprised of (a) minimum base rent, which includes rental revenues recognized on a straight-line basis, (b) revenue from the recovery of operating expenses from our tenants, (c) provisions for doubtful accounts in the same quarter that we established the receivable, which include provisions for straight-line receivables, (d) revenue from the collection of lease termination fees and (e) parking and other tenant charges such as percentage rents.

Real estate rental revenue for same-store properties for the nine months ended September 30,2017 and 2016 was as follows (in thousands):

	Nine Months Ended September 30,
	2017			2016			$ Change			% Change
Minimum base rent	$	173,494		$	165,110		$	8,384		5.1	%
Recoveries from tenants	23,667			23,104			563			2.4	%
Provision for doubtful accounts	(992		)	(679		)	(313		)	(46.1	)%
Lease termination fees	1,624			917			707			77.1	%
Parking and other tenant charges	7,577			7,020			557			7.9	%
Total same-store real estate rental revenue	$	205,370		$	195,472		$	9,898		5.1	%

• Minimum base rent: Increase primarily due to higher rental income ($9.4 million), partially offset by higher abatements ($1.0 million).

29

• Recoveries from tenants:Increase primarily due to higher periodic settlements of tenant recoveries ($0.5 million) and higher reimbursements for real estate taxes ($0.1 million).

• Provision for doubtful accounts:Increase primarily due to higher provisions in the retail segment ($0.3 million).

• Lease termination fees: Increase primarily due to higher fees in the office ($0.5 million) and retail ($0.2 million) segments.

• Parking and other tenant charges: Increase primarily due to higher parking income ($0.5 million).

Real estate rental revenue from same-store properties by segment was as follows (in thousands):

	Nine Months Ended September 30,
	2017		2016		$ Change		% Change
Office	$	103,289	$	95,253	$	8,036	8.4	%
Multifamily	55,260		54,355		905		1.7	%
Retail	46,821		45,864		957		2.1	%
Total same-store real estate rental revenue	$	205,370	$	195,472	$	9,898	5.1	%

• Office: Increase primarily due to higher rental income ($7.9 million), lease termination fees ($0.5 million), periodic settlements of tenant recoveries ($0.5 million) and parking income ($0.4 million), partially offset by higher rent abatements ($1.3 million).

• Multifamily: Increase primarily due to higher rental income ($0.9 million).

• Retail: Increase primarily due to higher rental income ($0.7 million), tenant reimbursements for income taxes ($0.3 million), lease termination fees ($0.2 million) and parking income ($0.1 million), partially offset by higher provisions for bad debt ($0.3 million).

Real estate rental revenue from acquisitions increased due to the acquisitions of Watergate 600 ($9.7 million) in the 2017 Period and Riverside Apartments ($8.7 million) in the 2016 Period.

Real estate rental revenue from development/redevelopment properties decreased primarily due to lower tenant reimbursements ($0.7 million) at Army Navy Building, which substantially completed redevelopment activities during the 2017 Quarter.

During the 2017 Period, we executed new and renewal leases in our office and retail segments as follows:

	Square Feet (in thousands)	Average Rental Rate (per square foot)		% Rental Rate Increase		Leasing Costs (1) (per square foot)		Free Rent (weighted average months)	Retention Rate
Office	411	$	44.53	8.0	%	$	88.74	10.3	48.0	%
Retail	255	29.00		17.7	%	13.26		1.4	68.6	%
Total	666	38.57		10.6	%	59.77		7.7	56.2	%

⁽¹⁾ Consists of tenant improvements and leasing commissions.

The low retention rate in the office segment is primarily due to the non-renewal of a large tenant at Braddock Metro Center. We have executed a lease with a new tenant for that space, with the lease expected to commence in 2018. Retail’s retention rate was negatively impacted by the bankruptcy of a large tenant at Frederick Crossing.

Real Estate Expenses

Real estate expenses as a percentage of revenue for the 2017 Period and 2016 Period were 35.4% and 36.4%, respectively.

Real estate expenses from same-store properties by segment were as follows (in thousands):

	Nine Months Ended September 30,
	2017		2016		$ Change			% Change
Office	$	38,533	$	37,017	$	1,516		4.1	%
Multifamily	21,633		21,725		(92		)	(0.4	)%
Retail	11,147		11,660		(513		)	(4.4	)%
Total same-store real estate expenses	$	71,313	$	70,402	$	911		1.3	%

• Office: Increase primarily due to higher real estate tax ($0.7 million), administrative ($0.3 million) and custodial ($0.3 million) expenses.

30

• Multifamily: Decrease primarily due to lower utilities ($0.3 million) and snow removal ($0.1 million) expenses, partially offset by higher real estate taxes ($0.3 million).

• Retail: Decrease primarily due to lower snow removal ($0.3 million) and bad debt ($0.3 million) expenses.

Other Income and Expenses

Depreciation and Amortization: Increase primarily due to the Watergate 600 acquisition ($4.8 million), partially offset by lower amortization of acquired intangible lease assets at Riverside Apartments ($1.9 million) and same-store properties ($1.8 million).

Acquisition Costs: The acquisition costs in 2016 are related to the acquisition of Riverside Apartments during the 2016 Period. We capitalized the costs associated with the acquisition of Watergate 600 in the 2017 Period due to accounting for the transaction as an asset acquisition in accordance with the adoption of ASU No. 2017-01, Business Combinations (Topic 805) - Clarifying the Definition of a Business.

General and Administrative Expenses: Increase primarily due to higher share based compensation expense ($0.9 million) due to a higher volume of forfeitures in 2016 and higher estimated STI compensation ($0.8 million) due to improved forecasted operating results.

Casualty gain: The casualty gain in the 2016 Period represents the gain recognized upon the receipt of insurance proceeds related to damage from a fire at Bethesda Hill Towers during the first quarter of 2015 that damaged four units.

Real estate impairment: Impairment charge during the 2017 Period to write down the carrying value of Braddock Metro Center to its estimated fair value (see note 3 to the consolidated financial statements).

Gain on sale of real estate: Decrease due to completion of the sales of Dulles Station II, 6110 Executive Boulevard, 51 Monroe Street, 600 Jefferson Plaza, West Gude Drive, 51 Monroe Street and One Central Plaza during the 2016 Period.

Interest Expense: Interest expense by debt type for the nine months ended September 30,2017 and 2016 were as follows (in thousands):

	Nine Months Ended September 30,
Debt Type	2017			2016			$ Change			% Change
Notes payable	$	28,042		$	24,946		$	3,096		12.4	%
Mortgage notes payable	3,651			12,628			(8,977		)	(71.1	)%
Lines of credit	4,617			4,255			362			8.5	%
Capitalized interest	(676		)	(476		)	(200		)	42.0	%
Total	$	35,634		$	41,353		$	(5,719	)	(13.8	)%

• Notes payable: Increase primarily due to executing the $150.0 million term loan in 2016, which has a floating interest rate effectively fixed at 2.9% by interest rate swaps. We borrowed $100.0 million on the term loan in the fourth quarter of 2016, and borrowed the remaining $50.0 million during the first quarter of 2017.

• Mortgage notes payable: Decrease primarily due to the repayment of the mortgage notes secured by John Marshall II, 3801 Connecticut Avenue, Bethesda Hill Apartments, Walker House Apartments, 2445 M Street and the Army Navy Building in 2017 and 2016.

• Lines of credit: Increase primarily due to a weighted average interest rate of 2.1% during the 2017 Period, as compared to 1.5% during the 2016 Period.

• Capitalized interest: Increase primarily due to capitalization of interest on spending related to the Trove, the multifamily development adjacent to The Wellington.

Income tax benefit: The income tax benefit in the 2016 Period resulted from a reduction of the valuation allowance on a deferred tax asset at one of our taxable REIT subsidiaries due to a net operating loss as a result of the sale of Dulles Station II. We further reduced the valuation allowance in the 2017 Period due to an increase in anticipated income at the TRS and corresponding usage of the net operating loss. We have concluded that there is sufficient positive evidence as of September 30, 2017 that it is more likely than not that a portion of the deferred tax asset related to the net operating loss is realizable.

Liquidity and Capital Resources

Capital Requirements

As of the end of the third quarter of 2017, we summarize our full-year 2017 capital requirements as follows:

• Funding dividends and distributions to our shareholders;

• $49.6 million to repay a secured note during the first quarter of 2017;

• Approximately $75 - $80 million to invest in our existing portfolio of operating assets, including approximately $25 - $30 million to fund tenant-related capital requirements and leasing commissions;

• Approximately $20 - $25 million to invest in our development and redevelopment projects; and

• Funding for potential property acquisitions during 2017, offset by proceeds from potential property dispositions.

Debt Financing

Our total debt at September 30, 2017 and December 31, 2016 was as follows (in thousands):

	September 30, 2017			December 31, 2016
Mortgage notes payable	$	92,671		$	144,485
Lines of credit	189,000			120,000

Debt issuance costs, net	(4,450		)	(5,244		)
Total	$	1,179,148		$	1,111,624

Mortgage Notes Payable

At September 30, 2017, our mortgage notes payable bore an effective weighted average fair value interest rate of 4.5% and had an estimated weighted average maturity of 3.7 years. We may either initiate secured mortgage debt or assume mortgage debt from time-to-time in conjunction with property acquisitions.

Our mortgage notes contain covenants with which we must comply. Failure to comply with any of the covenants under our mortgage notes could result in a default under one or more of our debt instruments. This could cause our debt holders to accelerate the timing of payments and would therefore have a material adverse effect on our business, operations, financial condition and liquidity. As of September 30, 2017, we were in compliance with our mortgage notes covenants.

Lines of Credit and Term Loan

Our primary source of liquidity is our Revolving Credit Facility, a $600.0 million unsecured credit agreement that matures in June 2019, unless extended pursuant to one or both of the two six-month extension options. The Revolving Credit Facility has an accordion feature that allows us to increase the facility to $1.0 billion, subject to the extent the lenders agree to provide additional revolving loan commitments or term loans. In September 2015, we entered into a $150.0 million unsecured term loan by exercising a portion of the accordion feature under the Revolving Credit Facility (as discussed below). The $600.0 million committed capacity of the unsecured line of credit under the Revolving Credit Facility was not changed as a result of the incurrence of the term loan. The Revolving Credit Facility bears interest at a rate of either one month LIBOR plus a margin ranging from 0.875% to 1.55% (depending on our credit rating) or the base rate plus a margin ranging from 0.0% to 0.55% (based upon our credit rating). The base rate is the highest of the administrative agent’s prime rate, the federal funds rate plus 0.50% and the one month LIBOR market index rate plus 1.0%. In addition, the Revolving Credit Facility requires the payment of a facility fee ranging from 0.125% to 0.30% (depending on our credit rating) on the $600.0 million committed capacity, without regard to usage. As of September 30, 2017, the interest rate on the facility is one month LIBOR plus 1.00% and the facility fee is 0.20%. We had $189.0 million in borrowings outstanding as of September 30, 2017.

During the third quarter of 2015, we executed a $150.0 million unsecured term loan by exercising a portion of the accordion feature under the Revolving Credit Facility. The term loan has a 5.5 year term scheduled to mature onMarch 15, 2021and currently has an interest rate of one month LIBOR plus 110 basis points, based on our current unsecured debt ratings. We entered into two interest rate swap arrangements with a total notional amount of $150.0 million to swap the floating interest rate under the term loan to an all-in fixed interest rate of 2.7% starting on October 15, 2015 and extending until the maturity of the term loan on March 15, 2021.

32

The Revolving Credit Facility contains financial and other covenants with which we must comply. Failure to comply with any of the covenants under the Revolving Credit Facility or other debt instruments could result in a default under one or more of our debt instruments. This could cause our lenders to accelerate the timing of payments and could therefore have a material adverse effect on our business, operations, financial condition and liquidity. In addition, our ability to draw on the Revolving Credit Facility or incur other unsecured debt in the future could be restricted by the loan covenants. As of September 30, 2017, we were in compliance with our loan covenants.

Notes Payable

We generally issue unsecured notes to fund our real estate assets long-term. In issuing future unsecured notes, we intend to ladder the maturities of our debt to mitigate exposure to interest rate risk in future years.

During the third quarter of 2016, we entered into a seven year, $150.0 million unsecured term loan (“2016 Term Loan”) maturing on July 21, 2023 with a deferred draw period of up to six months commencing on July 22, 2016. The 2016 Term Loan bears interest at a rate of either LIBOR plus a margin ranging from 1.50% to 2.45% or the base rate plus a margin ranging from 0.5% to 1.45% (in each case depending upon our credit rating). The base rate is the highest of the administrative agent’s prime rate, the federal funds rate plus 0.50% and one-month LIBOR plus 1.0%. The 2016 Term Loan currently has an interest rate of one month LIBOR plus 165 basis points, based on our current unsecured debt ratings. We borrowed $100.0 million on the term loan in the fourth quarter of 2016, and borrowed the remaining $50.0 million during the first quarter of 2017. We used the proceeds to refinance maturing secured debt. We also entered into forward interest rate swaps commencing on March 31, 2017 to effectively fix the interest rate on the 2016 Term Loan at 2.9% (see note 7 to the consolidated financial statements).

Our unsecured notes contain covenants with which we must comply. Failure to comply with any of the covenants under our unsecured notes could result in a default under one or more of our debt instruments. This could cause our debt holders to accelerate the timing of payments and would therefore have a material adverse effect on our business, operations, financial condition and liquidity. As of September 30, 2017, we were in compliance with our unsecured notes covenants. In addition, our ability to draw on our Revolving Credit Facility or incur other unsecured debt in the future could be restricted by our unsecured note covenants.

From time to time, we may seek to repurchase and cancel our outstanding notes through open market purchases, privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors.

Common Equity

We have authorized for issuance 100.0 million common shares, of which 78.5 million shares were outstanding at September 30, 2017.

On June 23, 2015, we entered into four separate equity distribution agreements (collectively, the “Equity Distribution Agreements”) with each of Wells Fargo Securities, LLC, BNY Mellon Capital Markets, LLC, Citigroup Global Markets Inc. and RBC Capital Markets, LLC relating to the issuance of up to $200.0 million of our common shares from time to time. Issuances of our common shares are made at market prices prevailing at the time of issuance. We may use net proceeds from the issuance of common shares under this program for general corporate purposes, including, without limitation, working capital, the acquisition, renovation, expansion, improvement, development or redevelopment of income producing properties or the repayment of debt. During the 2017 Period, we issued 3.6 million common shares under the Equity Distribution Agreements at an average price of $32.06 per share, raising $113.2 million in net proceeds.

We have a dividend reinvestment program, whereby shareholders may use their dividends and optional cash payments to purchase common shares. The common shares sold under this program may either be common shares issued by us or common shares purchased in the open market. During the 2017 Period, we issued 77,153 common shares under this program at a weighted average price of $32.24 per share, raising $2.5 million in net proceeds.

Preferred Equity

Washington REIT’s board of trustees can, at its discretion, authorize the issuance of up to 10.0 million preferred shares. The ability to issue preferred equity provides Washington REIT an additional financing tool that may be used to raise capital for future acquisitions or other business purposes. As of September 30, 2017, no preferred shares had been issued.

33

Dividends

We currently declare dividends quarterly at a rate of $0.30 per share. The maintenance of our dividend level is subject to various factors reviewed by the board of trustees in its discretion. These factors include our results of operations, the availability of cash and the REIT distribution requirements, which require at least 90% of our REIT taxable income to be distributed to shareholders on an annual basis. When setting the dividend level, our board of trustees looks in particular at trends in our level of funds from operations, together with associated recurring capital improvements, tenant improvements, leasing commissions and incentives, and adjustments to straight-line rents to reflect cash rents received.

Our dividend and distribution payments for the three and nine months ended September 30, 2017 and 2016 are as follows (in thousands):

	Three Months Ended September 30,				Change					Nine Months Ended September 30,				Change
	2017		2016		$			%		2017		2016		$			%
Common dividends	$	23,493	$	22,365	$	1,128		5.0	%	$	91,666	$	85,648	$	6,018		7.0	%
Distributions to noncontrolling interests	8		33		(25		)	(75.8	)%	67		143		(76		)	(53.1	)%
	$	23,501	$	22,398	$	1,103		4.9	%	$	91,733	$	85,791	$	5,942		6.9	%

Dividends paid during the 2017 Quarter and 2017 Period increased primarily due to the issuance of 6.2 million common shares during 2016 and 3.6 million common shares during 2017.

Historical Cash Flows

Cash flows from operations are an important factor in our ability to sustain our dividend at its current rate. If our cash flows from operations were to decline significantly from current levels, we may have to reduce our dividend. Consolidated cash flow information is summarized as follows (in thousands):

	Nine Months Ended September 30,						Change
	2017			2016			$			%
Net cash provided by operating activities	$	94,271		$	85,764		$	8,507		9.9	%
Net cash used in investing activities	(184,504		)	(39,097		)	(145,407		)	(371.9	)%
Net cash provided by (used in) financing activities	90,254			(61,904		)	152,158			245.8	%

Cash provided by operating activities increased primarily due to the acquisitions of Riverside Apartments and Watergate 600 and lower interest payments, partially offset by property sales during the 2016 Period.

Cash used in investing activities increased primarily due to proceeds from properties sold in the 2016 Period, partially offset by lower expenditures on acquisitions in the 2017 Period.

Cash provided by financing activities increased primarily due to paying off a larger volume of mortgage notes in the 2016 Period, higher net borrowing on our Revolving Credit Facility during the 2017 Period and drawing the remaining $50.0 million on a term loan during the 2017 Period, partially offset by lower proceeds from equity issuances during the 2017 Period.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements as of September 30, 2017 that are reasonably likely to have a current or future material effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Funds From Operations

NAREIT FFO is a widely used measure of operating performance for real estate companies. We provide NAREIT FFO as a supplemental measure to net income calculated in accordance with GAAP. Although NAREIT FFO is a widely used measure of operating performance for REITs, NAREIT FFO does not represent net income calculated in accordance with GAAP. As such, it should not be considered an alternative to net income as an indication of our operating performance. In addition, NAREIT FFO does not represent cash generated from operating activities in accordance with GAAP, nor does it represent cash available to pay distributions and should not be considered as an alternative to cash flow from operating activities, determined in accordance with GAAP, as a measure of our liquidity. In its April, 2002 White Paper, the National Association of Real Estate Investment Trusts, Inc. (“NAREIT”) defines NAREIT FFO as net income (computed in accordance with GAAP) excluding gains (or losses) associated with sales of properties, impairments of depreciable real estate, and real estate depreciation and amortization. We consider NAREIT FFO to be a standard supplemental measure for REITs because it facilitates an understanding of the operating performance of our properties without giving effect to real estate depreciation and amortization, which historically assumes that the value of real estate assets diminishes predictably over time. Since real estate values have instead historically risen or fallen with market conditions, we believe that NAREIT FFO more accurately provides investors an indication of our ability to incur and service debt, make capital expenditures and fund other needs. Our NAREIT FFO may not be comparable to FFO reported by other REITs. These other REITs may not define the term in accordance with the current NAREIT definition or may interpret the current NAREIT definition differently. NAREIT FFO is a non-GAAP measure.

The following table provides the calculation of our NAREIT FFO and a reconciliation of NAREIT FFO to net income for the three months ended September 30,2017 and 2016 (in thousands):

	Three Months Ended September 30,					Nine Months Ended September 30,

Critical Accounting Policies and Estimates

We base the discussion and analysis of our financial condition and results of operations upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. We discuss the most critical estimates in our Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on February 21, 2017.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The principal material financial market risk to which we are exposed is interest rate risk. Our exposure to market risk for changes in interest rates relates primarily to refinancing long-term fixed rate obligations, the opportunity cost of fixed rate obligations in a falling interest rate environment and our variable rate lines of credit.

The table below presents principal, interest and related weighted average fair value interest rates by year of maturity, with respect to debt outstanding on September 30, 2017.

⁽¹⁾ Includes two separate $150.0 million term loans with floating interest rates that are effectively fixed at 2.7% and 2.9% by interest rate swap arrangements.

⁽²⁾ Excludes net discounts of $3.6 million and net unamortized debt issuance costs of $0.2 million at September 30, 2017.

On September 15, 2015, we entered into two interest rate swap arrangements with a total notional amount of $150.0 million to swap the floating interest rate under our new $150.0 million term loan to an all-in fixed interest rate of 2.7% starting on October 15, 2015 and extending until the maturity of the term loan on March 15, 2021. On July 22, 2016, we entered into two forward interest rate swap arrangements with a total notional amount of $150.0 million to swap the floating interest rate under the 2016 Term Loan (see note 6 to the consolidated financial statements) to an all-in fixed interest rate of 2.9%, starting on March 31, 2017 and extending until the maturity of the 2016 Term Loan on July 21, 2023 (see note 7 to the consolidated financial statements).

We entered into the interest rate swap arrangements designated and qualifying as cash flow hedges to reduce our exposure to the variability in future cash flows attributable to changes in interest rates. Derivative instruments expose us to credit risk in the event of non-performance by the counterparty under the terms of the interest rate hedge agreement. We believe that we minimize our credit risk on these transactions by dealing with major, creditworthy financial institutions. As part of our ongoing control procedures, we monitor the credit ratings of counterparties and our exposure to any single entity, thus minimizing our credit risk concentration.

We enter into debt obligations primarily to support general corporate purposes including acquisition of real estate properties, capital improvements and working capital needs.

As the majority of our outstanding debt is long-term, fixed rate debt, our interest rate risk has not changed significantly from what was disclosed in our Annual Report on Form 10-K for the year ended December 31, 2016 filed with the SEC on February 21, 2017. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Debt Financing.”

ITEM 4: CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer and Controller, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer and Controller, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer and Controller concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

During the third quarter of 2017, we implemented upgrades to our accounting information systems. The implementation of our upgraded systems was not made in response to any identified deficiency or weakness in our internal controls over financial reporting. The implementation was subject to various testing and review procedures prior to and after execution. We have updated our internal controls over financial reporting, as necessary, to accommodate any modifications to our business processes or accounting procedures due to the implementation. Management does not believe that the implementation of the upgraded systems has had an adverse effect on our internal controls over financial reporting and will continue to monitor, test and evaluate the systems during the post-implementation period to ensure that adequate controls over financial reporting continue to be maintained.

There have not been any other changes in Washington REIT’s internal control over financial reporting (as defined by Rule 13a-15(f)) that occurred during the period covered by the report that have materially affected, or are reasonably likely to materially affect, Washington REIT’s internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature of Business

NATURE OF BUSINESS

Washington Real Estate Investment Trust (“Washington REIT”), a Maryland real estate investment trust, is a self-administered equity real estate investment trust, successor to a trust organized in 1960. Our business consists of the ownership and operation of income producing real estate properties in the greater Washington metro region. We own a diversified portfolio of office buildings, multifamily buildings and retail centers.

Federal Income Taxes

We believe that we qualify as a Real Estate Investment Trust (“REIT”) under Sections 856-860 of the Internal Revenue Code and intend to continue to qualify as such. To maintain our status as a REIT, we are, among other things, required to distribute 90% of our REIT taxable income (which is, generally, our ordinary taxable income, with certain modifications), excluding any net capital gains and any deductions for dividends paid to our shareholders on an annual basis. When selling a property, we generally have the option of (a) reinvesting the sales proceeds of property sold, in a way that allows us to defer recognition of some or all taxable gain realized on the sale, (b) distributing gains to the shareholders with no tax to us or (c) treating net long-term capital gains as having been distributed to our shareholders, paying the tax on the gain deemed distributed and allocating the tax paid as a credit to our shareholders.

Generally, and subject to our ongoing qualification as a REIT, no provisions for income taxes are necessary except for taxes on undistributed taxable income and taxes on the income generated by our taxable REIT subsidiaries (“TRSs”). Our TRSs are subject to corporate federal and state income tax on their taxable income at regular statutory rates, or as calculated under the alternative minimum tax, as appropriate. As of September 30, 2017 and December 31, 2016, our TRSs had deferred tax assets of $0.6 million and $0.5 million, respectively, net of valuation allowances of $2.7 million and $2.9 million, respectively. During the 2017 Period (as defined below), we recognized a deferred tax liability of $0.6 million in connection with the acquisition of Watergate 600 (see note 3). As of September 30, 2017 and December 31, 2016, we had net deferred tax liabilities of $1.0 million and $0.4 million, respectively. The deferred tax liabilities are primarily related to temporary differences in the timing of the recognition of revenue, amortization and depreciation.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATIONS

Significant Accounting Policies

We have prepared our consolidated financial statements using the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2016.

Pronouncements Not Yet Adopted

In August 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging:Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update, or alternatively requires adoption for fiscal years beginning after December 15, 2018. This adoption method will require us to recognize the cumulative effect of initially applying the ASU, if any, as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. While we continue to assess all potential impacts of the standard, we do not expect adoption to have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting, which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The new standard is effective for all entities for fiscal years beginning after December 15, 2017 and for interim periods therein. Early adoption is permitted. We do not expect the new standard to have a material impact on our consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash,which requires that restricted cash and cash equivalents be included with cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the consolidated statements of cash flows. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein, with early adoption permitted. We are currently evaluating the impact the new standard may have on Washington REIT’s consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments,which provides specific guidance on how cash receipts and payments should be presented and classified in the statement of cash flows for eight specific issues. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein, with early adoption permitted. We are currently evaluating the impact the new standard may have on Washington REIT’s consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments,which requires financial assets measured at an amortized cost basis, including trade receivables, to be presented at the net amount expected to be collected. The new standard is effective for public entities for fiscal years beginning after December 15, 2019 and for interim periods therein with adoption one year earlier permitted. We are currently evaluating the impact the new standard may have on Washington REIT’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”), which amends existing accounting standards for lease accounting, including by requiring lessees to recognize most leases on the balance sheet and making certain changes to lessor accounting. The new standard is effective for public entities for fiscal years beginning after December 15, 2018 and for interim periods therein with early adoption permitted. Upon adoption, for leases in which we are the lessor, the lease contract will be separated into lease and non-lease components in accordance with the provisions outlined within ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The lease component of the contract will be recognized on a straight-line basis in accordance with ASU 2016-02, while the non-lease component will be recognized under the provisions of ASU 2014-09. For lease contracts with a duration of more than one year in which we are the lessee, the present value of future lease payments will be recognized on our balance sheet as a right-of-use asset and a corresponding lease liability. Also, only direct leasing costs may be capitalized under the new standard, while current accounting standards allow for the capitalization of indirect leasing costs. We are currently evaluating the impact ASU 2016-02 may have on Washington REIT’s consolidated financial statements.

In June 2014, the FASB issued ASU 2014-09, which creates a single source of revenue guidance. The new standard provides accounting guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to their customers (unless the contracts are in the scope of other U.S. generally accepted accounting principles (“GAAP”) requirements, such as the leasing literature). The guidance also provides a model for the measurement and recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein. Early adoption is permitted for public entities beginning after December 15, 2016. We intend to adopt the new standard using the modified retrospective method. Upon adoption of ASU 2016-02, the majority of our revenue will be subject to the allocation provisions outlined within the revenue standard. We are currently evaluating the specific implementation requirements for allocating the consideration within our contracts in accordance with ASU 2014-09. We do not expect the new standard to have a material impact on the measurement and recognition of gains and losses on the sale of properties.

Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements include the consolidated accounts of Washington REIT, our majority-owned subsidiaries and entities in which Washington REIT has a controlling interest, including where Washington REIT has been determined to be a primary beneficiary of a variable interest entity (“VIE”). See note 3 for additional information on the property for which there is a noncontrolling interest. All intercompany balances and transactions have been eliminated in consolidation.

We have prepared the accompanying unaudited financial statements pursuant to the rules and regulations of the Securities and Exchange Commission “SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although we believe that the disclosures made are adequate to make the information presented not misleading. In addition, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results for the periods presented have been included. These unaudited financial statements should be read in conjunction with the financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Within these notes to the financial statements, we refer to the three months ended September 30, 2017 and September 30, 2016 as the “2017 Quarter” and the “2016 Quarter,” respectively and the nine months ended September 30, 2017 and September 30, 2016 as the "2017 Period" and "2016 Period," respectively.

Use of Estimates in the Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

REAL ESTATE

Acquisition

Our current strategy is focused on properties inside the Washington metro region’s Beltway, near major transportation nodes and in areas with strong employment drivers and superior growth demographics. We seek to upgrade our portfolio with acquisitions as appropriate opportunities arise. We acquired the following property during the 2017 Period (the “2017 acquisition”):

Acquisition Date	Property	Type	Net Rentable Square Feet	Contract Purchase Price (In thousands)
April 4, 2017	Watergate 600	Office	293,000	$	135,000

The results of operations from the 2017 acquisition are included in the consolidated statements of income from the acquisition date and are as follows (in thousands):

	Three Months Ended September 30, 2017		Nine Months Ended September 30, 2017
Real estate rental revenue	$	4,831	$	9,733
Net income	356		1,320

We accounted for the acquisition of Watergate 600 as an asset acquisition. Accordingly, we capitalized $2.8 million of costs directly associated with the acquisition. We measured the value of the acquired physical assets (land and building), in-place leases (tenant origination costs, leasing commissions, absorption costs and lease intangible assets/liabilities), and any other liabilities by allocating the total cost of the acquisition on a relative fair value basis.

We have recorded the total cost of the 2017 acquisition as follows (in thousands):

Land	$	45,981
Building	66,241
Tenant origination costs	12,084
Leasing commissions/absorption costs	23,161
Lease intangible assets	498
Lease intangible liabilities	(9,585		)
Deferred tax liability	(560		)
Total	$	137,820

The weighted remaining average life for the 2017 acquisition components above, other than land, building and deferred tax liability, are 92 months for tenant origination costs, 85 months for leasing commissions/absorption costs, 16 months for net lease intangible assets and 105 months for net lease intangible liabilities.

The difference in the total contract purchase price of $135.0 million for the 2017 acquisition and cash paid for the acquisition per the consolidated statements of cash flows of $138.4 million is primarily due to capitalized acquisition-related costs ($2.8 million) and a net credit to the buyer for certain expenditures ($1.0 million), partially offset by the issuance of 12,124 operating partnership units (“Operating Partnership Units”) as part of the consideration ($0.4 million). The Operating Partnership Units are units in WashREIT Watergate 600 OP LP, a consolidated subsidiary of Washington REIT. These Operating Partnership Units may be redeemed for either cash equal to the fair market value of a share of Washington REIT common stock at the time of redemption (based on a 20-day average price) or, at the option of Washington REIT, one registered or unregistered share of Washington REIT common stock. In connection with the 2017 acquisition, we granted registration rights to the two contributors of the Watergate 600 property relating to the resale of any shares issued upon exchange of Operating Partnership Units pursuant to a shelf registration statement that we have an obligation to make available to the contributors approximately one year after the issuance of the Operating Partnership Units.

Development/Redevelopment

We have properties under development/redevelopment and held for current or future development as of September 30, 2017. In the office segment, we have a redevelopment project at the Army Navy Building, an office property in Washington, DC, to upgrade its common areas and add significant amenities in order to make the property more competitive within its sub-market. As of September 30, 2017, we had invested $4.4 million in the redevelopment and have placed $4.3 million of the project into service. We have substantially completed the additional amenities and common areas and expect to place 11th floor common areas into service by the end of 2017.

In the multifamily segment, we have The Trove, a multifamily development adjacent to The Wellington, and own land held for future multifamily development adjacent to Riverside Apartments. As of September 30, 2017, we had invested $27.3 million and $19.0 million, including the costs of acquired land, in The Trove and the development adjacent to Riverside Apartments, respectively.

In the retail segment, we currently have a redevelopment project to add rentable space at Spring Valley Village. As of September 30, 2017, we had invested $2.5 million in the redevelopment.

Variable Interest Entity

In June 2011, we executed a joint venture operating agreement with a real estate development company to develop The Maxwell, a mid-rise multifamily property at 650 North Glebe Road in Arlington, Virginia. Major construction activities at The Maxwell ended during December 2014, and the building became available for occupancy during the first quarter of 2015. Washington REIT was the 90% owner of the joint venture. The real estate development company owned 10% of the joint venture and was responsible for the development and construction of the property. Subsequent to the end of the 2017 Quarter, we purchased the remaining 10% of the joint venture from the real estate development company for a contract purchase price of $4.1 million. Upon the completion of this transaction, the joint venture was dissolved and Washington REIT became sole owner of The Maxwell.

We determined that, prior to completion of this transaction, The Maxwell joint venture was a VIE primarily based on the fact that the equity investment at risk was not sufficient to permit the entity to finance its activities without additional financial support. We also determined that Washington REIT was the primary beneficiary of the VIE due to the fact that Washington REIT was determined to have a controlling financial interest in the entity. In January 2016, Washington REIT exercised its right to purchase at par The Maxwell’s construction loan from the original third-party lender. Upon the purchase, the construction loan became an intercompany loan payable from the consolidated VIE to Washington REIT that is eliminated in consolidation. Subsequent to the 2017 Quarter, the intercompany loan payable was extinguished as part of the Washington REIT’s purchase of the joint venture partner’s 10%interest.

As of September 30, 2017 and December 31, 2016, The Maxwell’s assets were as follows (in thousands):

	September 30, 2017			December 31, 2016
Land	$	12,851		$	12,851
Income producing property	37,960			37,949
Accumulated depreciation and amortization	(6,255		)	(4,571		)
Other assets	1,016			456
	$	45,572		$	46,685

As of September 30, 2017 and December 31, 2016, The Maxwell’s liabilities were as follows (in thousands):

	September 30, 2017		December 31, 2016
Mortgage notes payable (1)	$	31,580	$	31,869
Accounts payable and other liabilities	395		186
Tenant security deposits	94		99
	$	32,069	$	32,154

⁽¹⁾ The mortgage notes payable balances as of September 30, 2017 and December 31, 2016 are eliminated in consolidation due to the purchase of the loan by Washington REIT in January 2016.

Properties Sold and Held for Sale

We intend to hold our properties for investment with a view to long-term appreciation, to engage in the business of acquiring, developing and owning our properties, and to make occasional sales of the properties that no longer meet our long-term strategy or return objectives and where market conditions for sale are favorable. The proceeds from the sales may be reinvested into other properties, used to fund development operations or to support other corporate needs, or distributed to our shareholders. Depreciation on these properties is discontinued when classified as held for sale, but operating revenues, other operating expenses and interest continue to be recognized until the date of sale.

During the 2017 Quarter, we entered into negotiations to sell Braddock Metro Center, a 356,000 square foot office property in Alexandria, Virginia. Subsequent to the 2017 Quarter, we executed a letter of intent with a potential buyer for the property and are in the process of negotiating a purchase and sale agreement. Due to the negotiations to sell the property, we evaluated Braddock Metro Center for impairment. We recognized a $5.0 million impairment charge for the 2017 Quarter in order to reduce the carrying value of the property to its estimated fair value. We based this fair valuation on the expected net proceeds from a potential sale. There are few observable market transactions for similar properties. This fair valuation falls into Level 2 of the fair value hierarchy due to its reliance on a quoted price in a market that is not active. Braddock Metro Center does not meet the criteria for classification as held for sale as of September 30, 2017.

During the second quarter of 2017, we executed a purchase and sale agreement for the sale of Walker House Apartments, a multifamily property in Gaithersburg, Maryland, for a contract sale price of $32.2 million. We determined that the property met the criteria for classification as held for sale as of June 30, 2017, and the property continues to meet the criteria for classification as held for sale as of September 30, 2017. We closed on the sale on October 23, 2017.

We sold the following properties in 2016:

Disposition Date	Property Name	Segment	Number of Units/ Rentable Square Feet	Contract Sales  Price (in thousands)		Gain on Sale (in thousands)
May 26, 2016	Dulles Station II (1)	Office	N/A	$	12,100	$	527
June 27, 2016	Maryland Office Portfolio Transaction I (2)	Office	692,000	111,500		23,585
September 22, 2016	Maryland Office Portfolio Transaction II (3)	Office	491,000	128,500		77,592
	Total 2016		1,183,000	$	252,100	$	101,704

⁽¹⁾  Land held for future development and an interest in a parking garage.

⁽²⁾  Maryland Office Portfolio Transaction I consists of 6110 Executive Boulevard, 600 Jefferson Plaza, Wayne Plaza and West Gude Drive.

⁽³⁾  Maryland Office Portfolio Transaction II consists of 51 Monroe Street and One Central Plaza.

While the sale of the Maryland Office Portfolio, in the aggregate, constituted an individually significant disposition, the Maryland Office Portfolio does not qualify for presentation and disclosure as a discontinued operation as it does not represent a strategic shift in our operations. Real estate rental revenue and net income for the Maryland Office Portfolio for the three and nine months endedSeptember 30, 2017 and 2016 are as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2017		2016		2017		2016
Real estate rental revenue	$	—	$	3,689	$	—	$	20,266
Net income	—		2,474		—		9,376

We do not have significant continuing involvement in the operations of the disposed properties.

Unsecured Lines of Credit Payable

UNSECURED LINES OF CREDIT PAYABLE

We have a $600.0 million unsecured revolving credit agreement (“Revolving Credit Facility”) that matures in June 2019, unless extended pursuant to one or both of the twosix months extension options. The Revolving Credit Facility has an accordion feature, which we utilized a portion of in September 2015, as described below, that allows us to increase the facility to $1.0 billion, subject to the extent the lenders agree to provide additional revolving loan commitments or term loans. In September 2015, we entered into a $150.0 million unsecured term loan (“2015 Term Loan”) by executing a portion of the accordion feature under the Revolving Credit Facility. The 2015 Term Loan has a 5.5 year term and currently has an interest rate of one month LIBOR plus 110 basis points, based on Washington REIT’s current unsecured debt ratings. We entered into two interest rate swaps to effectively fix the interest rate at 2.7% (see note 7).

The Revolving Credit Facility bears interest at a rate of either one month LIBOR plus a margin ranging from 0.875% to 1.55% or the base rate plus a margin ranging from 0.0% to 0.55% (in each case depending upon Washington REIT’s credit rating). The base rate is the highest of the administrative agent’s prime rate, the federal funds rate plus 0.50% and the LIBOR market index rate plus 1.0%. In addition, the Revolving Credit Facility requires the payment of a facility fee ranging from 0.125% to 0.30% (depending on Washington REIT’s credit rating) on the $600.0 million committed capacity, without regard to usage. As of September 30, 2017, the interest rate on the facility is one month LIBOR plus 1.00% and the facility fee is 0.20%.

The amount of the Revolving Credit Facility’s unsecured line of credit unused and available at September 30, 2017 is as follows (in thousands):

Committed capacity	$	600,000
Borrowings outstanding	(189,000		)
Unused and available	$	411,000

We executed borrowings and repayments on the Revolving Credit Facility during the 2017 Period as follows (in thousands):

During 2016, we entered into a seven year, $150.0 million unsecured term loan (“2016 Term Loan”) maturing on July 21, 2023 with a deferred draw period of up to six months commencing on July 22, 2016. The 2016 Term Loan bears interest at a rate of either LIBOR plus a margin ranging from 1.50% to 2.45% or the base rate plus a margin ranging from 0.5% to 1.45% (in each case depending upon Washington REIT’s credit rating). The base rate is the highest of the administrative agent’s prime rate, the federal funds rate plus 0.50% and one-month LIBOR plus 1.0%. The 2016 Term Loan currently has an interest rate of one month LIBOR plus 165 basis points, based on Washington REIT’s current unsecured debt ratings. We borrowed $100.0 million on the term loan in the fourth quarter of 2016, and borrowed the remaining $50.0 million during the first quarter of 2017. We have also previously entered into forward interest rate swaps commencing on March 31, 2017 to effectively fix the interest rate on the 2016 Term Loan at 2.9% (see note 7).

DERIVATIVE INSTRUMENTS

On September 15, 2015, we entered into two interest rate swap arrangements with a total notional amount of $150.0 million to swap the floating interest rate under the 2015 Term Loan (see note 5) to an all-in fixed interest rate of 2.7% starting on October 15, 2015 and extending until the maturity of the 2015 Term Loan on March 15, 2021. On July 22, 2016, we entered into two forward interest rate swap arrangements with a total notional amount of $150.0 million to swap the floating interest rate under the 2016 Term Loan (see note 6) to an all-in fixed interest rate of 2.9% starting on March 31, 2017 and extending until the maturity of the 2016 Term Loan on July 21, 2023.

The interest rate swaps qualify as cash flow hedges and are recorded at fair value in accordance with GAAP, based on discounted cash flow methodologies and observable inputs. We record the effective portion of changes in fair value of the cash flow hedges in other comprehensive income. The resulting unrealized gain (loss) on the effective portions of the cash flow hedges was the only activity in other comprehensive income during the periods presented in our consolidated financial statements. We assess the effectiveness of our cash flow hedges both at inception and on an ongoing basis. The cash flow hedges were effective for the 2017 Quarter and 2017 Period and 2016 Quarter and 2016 Period, and therefore hedge ineffectiveness did not impact earnings during the 2017 Quarter and 2017 Period and 2016 Quarter and 2016 Period.

The fair values of the interest rate swaps as of September 30, 2017 and December 31, 2016, are as follows (in thousands):

					Fair Value
					Asset Derivatives
Derivative Instrument	Aggregate Notional Amount		Effective Date	Maturity Date	September 30, 2017		December 31, 2016
Interest rate swaps	$	150,000	October 15, 2015	March 15, 2021	$	747	$	417
Interest rate swaps	150,000		March 31, 2017	July 21, 2023	6,101		7,194
	$	300,000			$	6,848	$	7,611

We record interest rate swaps on our consolidated balance sheets with prepaid expenses and other assets when in a net asset position and with accounts payable and other liabilities when in a net liability position. The interest rate swaps have been effective since inception. The net gains or losses on the effective swaps are recognized in other comprehensive income, as follows (in thousands):

	Three Months Ended September 30,					Nine Months Ended September 30,
	2017			2016		2017			2016
Unrealized (loss) gain on interest rate hedges	$	(9	)	$	739	$	(763	)	$	(4,320	)

Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the next twelve months, we estimate that an additional $0.1 million will be reclassified as decrease to interest expense.

We have agreements with each of our derivative counterparties that contain a provision whereby we could be declared in default on our derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness. As of September 30, 2017, the fair value of derivatives is in a net asset position of $6.8 million, which includes accrued interest but excludes any adjustment for nonperformance risk. As of September 30, 2017, we have not posted any collateral related to these agreements.

Derivative instruments expose us to credit risk in the event of non-performance by the counterparty under the terms of the interest rate hedge agreement. We believe that we minimize our credit risk on these transactions by dealing with major, creditworthy financial institutions. We monitor the credit ratings of counterparties and our exposure to any single entity, thus minimizing our credit risk concentration.

Fair Value Disclosures [Abstract]

Fair Value Disclosures

FAIR VALUE DISCLOSURES

Assets and Liabilities Measured at Fair Value

For assets and liabilities measured at fair value on a recurring basis, quantitative disclosures about the fair value measurements are required to be disclosed separately for each major category of assets and liabilities, as follows:

Level 1: Quoted prices in active markets for identical assets

Level 2: Significant other observable inputs

Level 3: Significant unobservable inputs

The only assets or liabilities we had at September 30, 2017 and December 31, 2016 that are recorded at fair value on a recurring basis are the assets held in the Supplemental Executive Retirement Plan (“SERP”), which primarily consist of investments in mutual funds, and the interest rate swaps (see note 7).

We base the valuations related to the SERP on assumptions derived from significant other observable inputs and accordingly these valuations fall into Level 2 in the fair value hierarchy.

The valuation of the interest rate swaps is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each interest rate swap. This analysis reflects the contractual terms of the interest rate swaps, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with the provisions of ASC 820, we incorporate credit valuation adjustments in the fair value measurements to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk. These credit valuation adjustments were concluded to not be significant inputs for the fair value calculations for the periods presented. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as the posting of collateral, thresholds, mutual puts and guarantees. The valuation of interest rate swaps fall into Level 2 in the fair value hierarchy.

The fair values of these assets and liabilities at September 30, 2017 and December 31, 2016 were as follows (in thousands):

	September 30, 2017								December 31, 2016
	Fair Value		Level 1		Level 2		Level 3		Fair Value		Level 1		Level 2		Level 3
Assets:
SERP	$	1,727	$	—	$	1,727	$	—	$	1,407	$	—	$	1,407	$	—
Interest rate swaps	6,848		—		6,848		—		7,611		—		7,611		—

Financial Assets and Liabilities Not Measured at Fair Value

The following disclosures of estimated fair value were determined by management using available market information and established valuation methodologies, including discounted cash flow. Many of these estimates involve significant judgment. The estimated fair value disclosed may not necessarily be indicative of the amounts we could realize on disposition of the financial instruments. The use of different market assumptions or estimation methodologies could have an effect on the estimated fair value amounts. In addition, fair value estimates are made at a point in time and thus, estimates of fair value subsequent to September 30, 2017 may differ significantly from the amounts presented.

Following is a summary of significant methodologies used in estimating fair values and a schedule of fair values at September 30, 2017 and December 31, 2016.

Cash and Cash Equivalents and Restricted Cash

Cash and cash equivalents and restricted cash include cash and commercial paper with original maturities of less than 90 days, which are valued at the carrying value, which approximates fair value due to the short maturity of these instruments (Level 1 inputs).

Notes Receivable

We acquired a note receivable (“2445 M Street note”) in 2008 with the purchase of 2445 M Street. We estimate the fair value of the 2445 M Street note based on a discounted cash flow methodology using market discount rates (Level 3 inputs).

Debt

Mortgage notes payable consist of instruments in which certain of our real estate assets are used for collateral. We estimate the fair value of the mortgage notes payable by discounting the contractual cash flows at a rate equal to the relevant treasury rates (with respect to the timing of each cash flow) plus credit spreads estimated through independent comparisons to real estate assets or loans with similar characteristics. Lines of credit payable consist of our bank facility which we use for various purposes including working capital, acquisition funding and capital improvements. The lines of credit advances and term loans with floating interest rates are priced at a specified rate plus a spread. We estimate the market value based on a comparison of the spreads of the advances to market given the adjustable base rate. We estimate the fair value of the notes payable by discounting the contractual cash flows at a rate equal to the relevant treasury rates (with respect to the timing of each cash flow) plus credit spreads derived using the relevant securities’ market prices. We classify these fair value measurements as Level 3 as we use significant unobservable inputs and management judgment due to the absence of quoted market prices.

As of September 30, 2017 and December 31, 2016, the carrying values and estimated fair values of our financial instruments were as follows (in thousands):

	September 30, 2017				December 31, 2016
	Carrying Value		Fair Value		Carrying Value		Fair Value
Cash and cash equivalents	$	11,326	$	11,326	$	11,305	$	11,305

Share-based Compensation [Abstract]

Stock Based Compensation

STOCK BASED COMPENSATION

Washington REIT maintains short-term (“STIP”) and long-term (“LTIP”) incentive plans that allow for stock based awards to officers and non-officer employees. Stock based awards are provided to officers and non-officer employees, as well as trustees, under the Washington Real Estate Investment Trust 2016 Omnibus Incentive Plan which allows for awards in the form of restricted shares, restricted share units, options and other awards up to an aggregate of 2,400,000 shares over the ten-year period in which the plan will be in effect. Restricted share units are converted into shares of our stock upon full vesting through the issuance of new shares.

Total Compensation Expense

Total compensation expense recognized in the consolidated financial statements for all outstanding share based awards was $1.2 million and $0.3 million for the 2017 Quarter and 2016 Quarter, respectively, and $3.6 million and $2.7 million for the 2017 Period and 2016 Period, respectively.

Restricted Share Awards

The total fair values of restricted share awards vested was $2.0 million and $2.5 million for the 2017 Period and 2016 Period, respectively.

The total unvested restricted share awards at September 30, 2017 was 355,120 shares, which had a weighted average grant date fair value of $30.86 per share. As of September 30, 2017, the total compensation cost related to unvested restricted share awards was $7.4 million, which we expect to recognize over a weighted average period of 37 months.

Earnings per Common Share

Earnings Per Share [Abstract]

Earnings per Common Share

EARNINGS PER COMMON SHARE

We determine “Basic earnings per share” using the two-class method as our unvested restricted share awards and units have non-forfeitable rights to dividends, and are therefore considered participating securities. We compute basic earnings per share by dividing net income attributable to the controlling interest less the allocation of undistributed earnings to unvested restricted share awards and units by the weighted-average number of common shares outstanding for the period.

We also determine “Diluted earnings per share” as the more dilutive of the two-class method or the treasury stock method with respect to the unvested restricted share awards. We further evaluate any other potentially dilutive securities at the end of the period and adjust the basic earnings per share calculation for the impact of those securities that are dilutive. Our diluted earnings per share calculation includes the dilutive impact of our share based awards with performance conditions prior to the grant date and awards with market conditions under the contingently issuable method. The dilutive earnings per share calculation also considers the Operating Partnership Units issued in connection with the 2017 acquisition, which were not dilutive for any of the periods presented.

The computations of basic and diluted earnings per share for the three and nine months ended September 30, 2017 and 2016 were as follows (in thousands, except per share data):

Segment Reporting [Abstract]

Segment Information

SEGMENT INFORMATION

We have three reportable segments: office, multifamily and retail. Office properties provide office space for various types of businesses and professions. Multifamily properties provide rental housing for individuals and families throughout the greater Washington metro region. Retail properties are typically grocery store-anchored neighborhood centers that include other small shop tenants or regional power centers with several junior box tenants.

We evaluate performance based upon net operating income from the combined properties in each segment. Our reportable operating segments are consolidations of similar properties. GAAP requires that segment disclosures present the measure(s) used by the chief operating decision maker for purposes of assessing segments’ performance. Net operating income is a key measurement of our segment profit and loss. Net operating income is defined as segment real estate rental revenue less segment real estate expenses.

The following tables present revenues, net operating income, capital expenditures and total assets for the three and nine months ended September 30, 2017 and 2016 from these segments, and reconcile net operating income of reportable segments to net income attributable to the controlling interests as reported (in thousands):

Equity [Abstract]

Shareholders' Equity

SHAREHOLDERS' EQUITY

On June 23, 2015, we entered into four separate equity distribution agreements (collectively, the “Equity Distribution Agreements”) with each of Wells Fargo Securities, LLC, BNY Mellon Capital Markets, LLC, Citigroup Global Markets Inc. and RBC Capital Markets, LLC relating to the issuance of up to $200.0 million of our common shares from time to time. Issuances of our common shares are made at market prices prevailing at the time of issuance. We may use net proceeds from the issuance of common shares under this program for general corporate purposes, including, without limitation, working capital, the acquisition, renovation, expansion, improvement, development or redevelopment of income producing properties or the repayment of debt. During the 2017 Quarter, we issued 1.5 million common shares under the Equity Distribution Agreements at an average price of $32.89 per share, raising $49.3 million in net proceeds. During the 2017 Period, we issued 3.6 million common shares under the Equity Distribution Agreements at an average price of $32.06 per share, raising $113.2 million in net proceeds.

We have a dividend reinvestment program, whereby shareholders may use their dividends and optional cash payments to purchase common shares. The common shares sold under this program may either be common shares issued by us or common shares purchased in the open market. During the 2017 Quarter, we issued 20,884 common shares under this program at a weighted average price of $32.79 per share, raising $0.7 million in net proceeds. During the 2017 Period, we issued 0.1 million common shares under the dividend reinvestment program at a weighted average price of $32.24 per share, raising $2.5 million in net proceeds.

Accounting Policies [Abstract]

Fiscal Period

Significant Accounting Policies

We have prepared our consolidated financial statements using the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2016.

New Accounting Pronouncements

Pronouncements Not Yet Adopted

In August 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2017-12, Derivatives and Hedging:Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update, or alternatively requires adoption for fiscal years beginning after December 15, 2018. This adoption method will require us to recognize the cumulative effect of initially applying the ASU, if any, as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. While we continue to assess all potential impacts of the standard, we do not expect adoption to have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting, which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The new standard is effective for all entities for fiscal years beginning after December 15, 2017 and for interim periods therein. Early adoption is permitted. We do not expect the new standard to have a material impact on our consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash,which requires that restricted cash and cash equivalents be included with cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the consolidated statements of cash flows. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein, with early adoption permitted. We are currently evaluating the impact the new standard may have on Washington REIT’s consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments,which provides specific guidance on how cash receipts and payments should be presented and classified in the statement of cash flows for eight specific issues. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein, with early adoption permitted. We are currently evaluating the impact the new standard may have on Washington REIT’s consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments,which requires financial assets measured at an amortized cost basis, including trade receivables, to be presented at the net amount expected to be collected. The new standard is effective for public entities for fiscal years beginning after December 15, 2019 and for interim periods therein with adoption one year earlier permitted. We are currently evaluating the impact the new standard may have on Washington REIT’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”), which amends existing accounting standards for lease accounting, including by requiring lessees to recognize most leases on the balance sheet and making certain changes to lessor accounting. The new standard is effective for public entities for fiscal years beginning after December 15, 2018 and for interim periods therein with early adoption permitted. Upon adoption, for leases in which we are the lessor, the lease contract will be separated into lease and non-lease components in accordance with the provisions outlined within ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The lease component of the contract will be recognized on a straight-line basis in accordance with ASU 2016-02, while the non-lease component will be recognized under the provisions of ASU 2014-09. For lease contracts with a duration of more than one year in which we are the lessee, the present value of future lease payments will be recognized on our balance sheet as a right-of-use asset and a corresponding lease liability. Also, only direct leasing costs may be capitalized under the new standard, while current accounting standards allow for the capitalization of indirect leasing costs. We are currently evaluating the impact ASU 2016-02 may have on Washington REIT’s consolidated financial statements.

In June 2014, the FASB issued ASU 2014-09, which creates a single source of revenue guidance. The new standard provides accounting guidance for all revenue arising from contracts with customers and affects all entities that enter into contracts to provide goods or services to their customers (unless the contracts are in the scope of other U.S. generally accepted accounting principles (“GAAP”) requirements, such as the leasing literature). The guidance also provides a model for the measurement and recognition of gains and losses on the sale of certain nonfinancial assets, such as property and equipment, including real estate. The new standard is effective for public entities for fiscal years beginning after December 15, 2017 and for interim periods therein. Early adoption is permitted for public entities beginning after December 15, 2016. We intend to adopt the new standard using the modified retrospective method. Upon adoption of ASU 2016-02, the majority of our revenue will be subject to the allocation provisions outlined within the revenue standard. We are currently evaluating the specific implementation requirements for allocating the consideration within our contracts in accordance with ASU 2014-09. We do not expect the new standard to have a material impact on the measurement and recognition of gains and losses on the sale of properties.

Principles of Consolidation and Basis of Presentation

Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements include the consolidated accounts of Washington REIT, our majority-owned subsidiaries and entities in which Washington REIT has a controlling interest, including where Washington REIT has been determined to be a primary beneficiary of a variable interest entity (“VIE”). See note 3 for additional information on the property for which there is a noncontrolling interest. All intercompany balances and transactions have been eliminated in consolidation.

Basis of Accounting

We have prepared the accompanying unaudited financial statements pursuant to the rules and regulations of the Securities and Exchange Commission “SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules and regulations, although we believe that the disclosures made are adequate to make the information presented not misleading. In addition, in the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results for the periods presented have been included. These unaudited financial statements should be read in conjunction with the financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Within these notes to the financial statements, we refer to the three months ended September 30, 2017 and September 30, 2016 as the “2017 Quarter” and the “2016 Quarter,” respectively and the nine months ended September 30, 2017 and September 30, 2016 as the "2017 Period" and "2016 Period," respectively

Use of Estimates in the Financial Statements

Use of Estimates in the Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
