EXPLANATORY NOTE

We refer to Highwoods Properties, Inc. as the “Company,” Highwoods Realty Limited Partnership as the “Operating Partnership,” the Company’s common stock as “Common Stock” or “Common Shares,” the Company’s preferred stock as “Preferred Stock” or “Preferred Shares,” the Operating Partnership’s common partnership interests as “Common Units” and the Operating Partnership’s preferred partnership interests as “Preferred Units.” References to “we” and “our” mean the Company and the Operating Partnership, collectively, unless the context indicates otherwise.

The Company conducts its activities through the Operating Partnership and is its sole general partner. The partnership agreement provides that the Operating Partnership will assume and pay when due, or reimburse the Company for payment of, all costs and expenses relating to the ownership and operations of, or for the benefit of, the Operating Partnership. The partnership agreement further provides that all expenses of the Company are deemed to be incurred for the benefit of the Operating Partnership.

Certain information contained herein is presented as of July 17, 2018, the latest practicable date for financial information prior to the filing of this Quarterly Report.

This report combines the Quarterly Reports on Form 10-Q for the period ended June 30, 2018 of the Company and the Operating Partnership. We believe combining the quarterly reports into this single report results in the following benefits:

• combined reports better reflect how management and investors view the business as a single operating unit;

• combined reports enhance investors' understanding of the Company and the Operating Partnership by enabling them to view the business as a whole and in the same manner as management;

• combined reports are more efficient for the Company and the Operating Partnership and result in savings in time, effort and expense; and

• combined reports are more efficient for investors by reducing duplicative disclosure and providing a single document for their review.

To help investors understand the significant differences between the Company and the Operating Partnership, this report presents the following separate sections for each of the Company and the Operating Partnership:

• Consolidated Financial Statements;

• Note 12 to Consolidated Financial Statements - Earnings Per Share and Per Unit;

• Item 4 - Controls and Procedures; and

• Item 6 - Certifications of CEO and CFO Pursuant to Sections 302 and 906 of the Sarbanes-Oxley Act.

1.    Description of Business and Significant Accounting Policies

Description of Business

Highwoods Properties, Inc. (the “Company”) is a fully integrated real estate investment trust (“REIT”) that provides leasing, management, development, construction and other customer-related services for its properties and for third parties. The Company conducts its activities through Highwoods Realty Limited Partnership (the “Operating Partnership”). At June 30, 2018, we owned or had an interest in 30.5 million rentable square feet of in-service properties, 2.0 million rentable square feet of properties under development and approximately 400 acres of development land.

The Company is the sole general partner of the Operating Partnership. At June 30, 2018, the Company owned all of the Preferred Units and 103.1 million, or 97.4%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.8 million Common Units. During the six months endedJune 30, 2018, the Company redeemed 23,196 Common Units for a like number of shares of Common Stock.

Basis of Presentation

Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).

The Company's Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership's Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. All intercompany transactions and accounts have been eliminated.

The unaudited interim consolidated financial statements and accompanying unaudited consolidated financial information, in the opinion of management, contain all adjustments (including normal recurring accruals) necessary for a fair presentation of our financial position, results of operations and cash flows. We have condensed or omitted certain notes and other information from the interim Consolidated Financial Statements presented in this Quarterly Report as permitted by SEC rules and regulations. These Consolidated Financial Statements should be read in conjunction with our 2017 Annual Report on Form 10-K.

Use of Estimates

The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.

Insurance

Beginning in 2018, we are primarily self-insured for health care claims for eligible participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities. At June 30, 2018, a reserve of $0.7 million was recorded to cover estimated reported and unreported claims.

Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that superseded the revenue recognition requirements under previous guidance, which we adopted as of January 1, 2018. Several updates have been issued subsequently which were intended to promote a more consistent interpretation and application of the principles outlined in the ASU. The ASU requires the use of a new five-step model to recognize revenue from contracts with customers. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We are also required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In analyzing our contracts with customers, we determined that the most material potential impact from the adoption of this ASU would be in how revenue is recognized for sales of real estate with continuing involvement. Prior to the adoption of this ASU, profit for such sales transactions was recognized and then reduced by the maximum exposure to loss related to the nature of the continuing involvement at the time of sale. Upon adoption of this ASU, any continuing involvement must be analyzed as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the continuing involvement performance obligation is satisfied, the sales price allocated to it will be recognized. We had no sales of real estate with continuing involvement during the first six months of2018 or prior periods; however, we will use such methodology for any future real estate sales with continuing involvement. Our internal controls with respect to accounting for such sales have been updated accordingly. The adoption of this ASU resulted in no other changes with respect to the timing of revenue recognition or internal controls related to our other contracts with customers which include primarily management, development and construction fees and transient parking income, all of which are not material to our Consolidated Financial Statements. As such, there is no cumulative-effect adjustment from the adoption of this ASU reflected in our Consolidated Financial Statements.

The FASB issued an ASU that requires entities to show changes in total cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of period balances rather than presented as transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. We adopted the ASU as of January 1, 2018 with retrospective application to our Consolidated Statements of Cash Flows. Accordingly, our Consolidated Statements of Cash Flows present a reconciliation of the changes in cash and cash equivalents and restricted cash. The effect of the adoption resulted in an $8.5 million increase in net cash used in investing activities for the six months endedJune 30, 2017. Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as construction-related escrows, property disposition proceeds set aside and designated or intended to fund future tax-deferred exchanges of qualifying real estate investments, escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements and any deposits made with lenders to unencumber secured properties.

The FASB issued an ASU that clarifies and narrows the definition of a business used in determining whether to account for a transaction as an asset acquisition or business combination. The guidance requires evaluation of the fair value of the assets acquired to determine if it is concentrated in a single identifiable asset or a group of similar identifiable assets. If so, the transferred assets would not be a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs. We adopted the ASU prospectively as of January 1, 2018. We expect that the majority of our future acquisitions would not meet the definition of a business; therefore, the related acquisition costs would be capitalized as part of the purchase price.

The FASB issued an ASU that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance requires modification accounting if the value, vesting conditions or classification of the award changes. We adopted the ASU as of January 1, 2018 with no effect on our Consolidated Financial Statements.

1.    Description of Business and Significant Accounting Policies – Continued

The FASB issued an ASU that sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. We are continuing to refine our analysis of the impact of the guidance on our Consolidated Financial Statements and the related internal controls and have an active project team working on the evaluation and implementation of the guidance. We continue to monitor FASB activity with respect to possible amendments to this ASU, particularly the FASB’s recent vote to finalize an amendment providing an optional practical expedient to lessors that removes the requirement to separate lease and non-lease components when the pattern of recognition of those components are the same and, when combined as a single unit, those would be classified as operating leases. Should the proposed amendment be issued, we expect to elect the practical expedient as our initial analysis of our leases indicates that the pattern of recognition of our material non-lease components (primarily cost recovery income) are the same as the lease components and will not require the use of the five-step revenue recognition model discussed above. We currently believe that the adoption of the ASU will not significantly change the accounting or the related internal controls for rental and other revenues from operating leases where we are the lessor, and that such leases will be accounted for in a manner similar to existing standards with the underlying leased asset being reported and recognized as a real estate asset. In addition, the guidance requires lessors to capitalize and amortize only incremental direct leasing costs. As a result, upon the adoption of the ASU, we will no longer be able to capitalize and amortize certain leasing related costs and instead will expense these costs as incurred. We are in the process of evaluating the impact to our results of operations of expensing such costs and any necessary changes to our related internal controls. The ASU is required to be adopted in 2019 using a modified retrospective approach which requires a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Leases where we are the lessee include primarily our operating ground leases. We expect to record right of use assets and the related liabilities for certain of these ground leases. We will continue to refine our evaluation and finalize our implementation plan throughout the remainder of 2018.

The FASB issued an ASU that eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item when the hedged item affects earnings. The ASU is required to be adopted in 2019 using a modified retrospective approach. We do not expect such adoption to have a material effect on our Consolidated Financial Statements.

The FASB issued an ASU that requires, among other things, the use of a new current expected credit loss ("CECL") model in determining our allowances for doubtful accounts with respect to accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable. The CECL model requires that we estimate our lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. We will also be required to disclose information about how we developed the allowances, including changes in the factors (e.g., portfolio mix, credit trends, unemployment, gross domestic product, etc.) that influenced our estimate of expected credit losses and the reasons for those changes. We will apply the ASU’s provisions as a cumulative-effect adjustment to retained earnings upon adoption in 2020. We are in the process of evaluating this ASU.

2.    Real Estate Assets

Acquisitions

During the first quarter of 2018, we acquired two development parcels totaling approximately nine acres in Nashville for an aggregate purchase price, including capitalized acquisition costs, of $50.6 million.

Dispositions

During the second quarter of 2018, we sold a building and various land parcels for an aggregate sale price of $34.0 million and recorded aggregate gains on disposition of property of $17.0 million.

3.    Mortgages and Notes Receivable

Mortgages and notes receivable were $5.9 million and $6.4 million at June 30, 2018 and December 31, 2017, respectively. We evaluate the ability to collect our mortgages and notes receivable by monitoring the leasing statistics and/or market fundamentals of these assets. As of June 30, 2018, our mortgages and notes receivable were not in default and there were no other indicators of impairment.

5.    Mortgages and Notes Payable

The following table sets forth our mortgages and notes payable:

	June 30, 2018			December 31, 2017
Secured indebtedness	$	98,089		$	98,981
Unsecured indebtedness	1,967,062			1,923,513
Less-unamortized debt issuance costs	(10,147		)	(8,161		)
Total mortgages and notes payable, net	$	2,055,004		$	2,014,333

At June 30, 2018, our secured mortgage loans were collateralized by real estate assets with an aggregate undepreciated book value of $147.4 million.

Our $600.0 million unsecured revolving credit facility is scheduled to mature in January 2022 and includes an accordion feature that allows for an additional $400.0 million of borrowing capacity subject to additional lender commitments. Assuming no defaults have occurred, we have an option to extend the maturity for two additional six-month periods. The interest rate at our current credit ratings is LIBOR plus 100 basis points and the annual facility fee is 20 basis points. There was $142.0 million and $136.0 million outstanding under our revolving credit facility at June 30, 2018 and July 17, 2018, respectively. At both June 30, 2018 and July 17, 2018, we had $0.4 million of outstanding letters of credit, which reduces the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility at June 30, 2018 and July 17, 2018 was $457.6 million and $463.6 million, respectively.

During the second quarter of 2018, we paid off at maturity $200.0 million principal amount of 7.5% unsecured notes.

During the first quarter of 2018, the Operating Partnership issued $350.0 million aggregate principal amount of 4.125% notes due 2028, less original issuance discount of $4.1 million. These notes were priced to yield 4.271%. Underwriting fees and other expenses were incurred that aggregated $2.9 million; these costs were deferred and will be amortized over the term of the notes.

We are currently in compliance with financial covenants with respect to our consolidated debt.

We have considered our short-term liquidity needs and the adequacy of our estimated cash flows from operating activities and other available financing sources to meet these needs. We intend to meet these short-term liquidity requirements through a combination of the following:

• available cash and cash equivalents;

• cash flows from operating activities;

• issuance of debt securities by the Operating Partnership (some of which debt securities may be hedged to a fixed interest rate pursuant to the forward-starting swaps referred to in Note 6);

• issuance of secured debt;

• bank term loans;

• borrowings under our revolving credit facility;

• issuance of equity securities by the Company or the Operating Partnership; and

• the disposition of non-core assets.

6. Derivative Financial Instruments

During the second quarter of 2018, we entered into $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 2.91% with respect to a planned issuance of debt securities by the Operating Partnership expected to occur prior to June 11, 2019.

During 2017, we entered into $150.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at 2.44% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $350.0 million aggregate principal amount of 4.125% notes due 2028 during the first quarter of 2018, we terminated the forward-starting swaps resulting in an unrealized gain of $7.0 million in accumulated other comprehensive income and a gain of $0.2 million of hedge ineffectiveness in interest expense.

The counterparties under our swaps are major financial institutions. The swap agreements contain a provision whereby if we default on certain of our indebtedness and which default results in repayment of such indebtedness being, or becoming capable of being, accelerated by the lender, then we could also be declared in default on our swaps.

Our interest rate swaps have been designated as and are being accounted for as cash flow hedges with the effective portion of changes in fair value recorded in other comprehensive income each reporting period. No significant gain or loss was recognized related to hedge ineffectiveness or to amounts excluded from effectiveness testing on our cash flow hedges during the six months endedJune 30, 2018 and 2017. We have no collateral requirements related to our interest rate swaps.

Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our debt. During the period from July 1, 2018 through June 30, 2019, we estimate that $2.5 million will be reclassified as a decrease to interest expense.

The following table sets forth the fair value of our derivatives:

	June 30, 2018		December 31, 2017
Derivatives:
Derivatives designated as cash flow hedges in prepaid expenses and other assets:
Interest rate swaps	$	2,871	$	1,286

8. Disclosure About Fair Value of Financial Instruments

The following summarizes the levels of inputs that we use to measure fair value.

Level 1.  Quoted prices in active markets for identical assets or liabilities.

Our Level 1 asset is our investment in marketable securities that we use to pay benefits under our non-qualified deferred compensation plan. Our Level 1 liability is our non-qualified deferred compensation obligation. The Company's Level 1 noncontrolling interests in the Operating Partnership relate to the ownership of Common Units by various individuals and entities other than the Company.

Level 2. Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.

Our Level 2 assets include the fair value of our mortgages and notes receivable and interest rate swaps. Our Level 2 liabilities include the fair value of our mortgages and notes payable.

8. Disclosure About Fair Value of Financial Instruments - Continued

The fair value of mortgages and notes receivable and mortgages and notes payable is estimated by the income approach utilizing contractual cash flows and market-based interest rates to approximate the price that would be paid in an orderly transaction between market participants. The fair value of interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments of interest rate swaps are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves. In addition, credit valuation adjustments are considered in the fair values to account for potential nonperformance risk, but were concluded to not be significant inputs to the calculation for the periods presented.

The following table sets forth our assets and liabilities and the Company's noncontrolling interests in the Operating Partnership that are measured or disclosed at fair value within the fair value hierarchy.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The Company is a fully integrated office real estate investment trust ("REIT") that owns, develops, acquires, leases and manages properties primarily in the best business districts (BBDs) of Atlanta, Greensboro, Memphis, Nashville, Orlando, Pittsburgh, Raleigh, Richmond and Tampa. The Company conducts its activities through the Operating Partnership. The Operating Partnership is managed by the Company, its sole general partner. Additional information about us can be found on our website at www.highwoods.com. Information on our website is not part of this Quarterly Report.

You should read the following discussion and analysis in conjunction with the accompanying Consolidated Financial Statements and related notes contained elsewhere in this Quarterly Report.

Disclosure Regarding Forward-Looking Statements

Some of the information in this Quarterly Report may contain forward-looking statements. Such statements include, in particular, statements about our plans, strategies and prospects under this section. You can identify forward-looking statements by our use of forward-looking terminology such as “may,” “will,” “expect,” “anticipate,” “estimate,” “continue” or other similar words. Although we believe that our plans, intentions and expectations reflected in or suggested by such forward-looking statements are reasonable, we cannot assure you that our plans, intentions or expectations will be achieved. When considering such forward-looking statements, you should keep in mind the following important factors that could cause our actual results to differ materially from those contained in any forward-looking statement:

• the financial condition of our customers could deteriorate;

• we may not be able to lease or re-lease second generation space, defined as previously occupied space that becomes available for lease, quickly or on as favorable terms as old leases;

• we may not be able to lease newly constructed buildings as quickly or on as favorable terms as originally anticipated;

• we may not be able to complete development, acquisition, reinvestment, disposition or joint venture projects as quickly or on as favorable terms as anticipated;

• development activity in our existing markets could result in an excessive supply relative to customer demand;

• our markets may suffer declines in economic and/or office employment growth;

• unanticipated increases in interest rates could increase our debt service costs;

• unanticipated increases in operating expenses could negatively impact our operating results;

• we may not be able to meet our liquidity requirements or obtain capital on favorable terms to fund our working capital needs and growth initiatives or repay or refinance outstanding debt upon maturity; and

Executive Summary

Our Strategic Plan focuses on:

• owning high-quality, differentiated office buildings in the BBDs of our core markets;

• improving the operating results of our properties through concentrated leasing, asset management, cost control and customer service efforts;

• developing and acquiring office buildings in BBDs that improve the overall quality of our portfolio and generate attractive returns over the long term for our stockholders;

• disposing of properties no longer considered to be core assets primarily due to location, age, quality and/or overall strategic fit; and

• maintaining a balance sheet with ample liquidity to meet our funding needs and growth prospects.

Revenues

Our operating results depend heavily on successfully leasing and operating the office space in our portfolio. Economic growth and office employment levels in our core markets are important factors, among others, in predicting our future operating results.

The key components affecting our rental and other revenues are average occupancy, rental rates, cost recovery income, new developments placed in service, acquisitions and dispositions. Average occupancy generally increases during times of improving economic growth, as our ability to lease space outpaces vacancies that occur upon the expirations of existing leases. Average occupancy generally declines during times of slower or negative economic growth, when new vacancies tend to outpace our ability to lease space. Asset acquisitions, dispositions and new developments placed in service directly impact our rental revenues and could impact our average occupancy, depending upon the occupancy rate of the properties that are acquired, sold or placed in service. A further indicator of the predictability of future revenues is the expected lease expirations of our portfolio. As a result, in addition to seeking to increase our average occupancy by leasing current vacant space, we also concentrate our leasing efforts on renewing existing leases prior to expiration. For more information regarding our lease expirations, see "Properties - Lease Expirations" in our 2017 Annual Report on Form 10-K. Occupancy in our office portfolio decreased from 92.9% at December 31, 2017 to 91.5% at June 30, 2018. We expect average occupancy for our office portfolio to be approximately 91% for the remainder of 2018.

Whether or not our rental revenue tracks average occupancy proportionally depends upon whether GAAP rents under signed new and renewal leases are higher or lower than the GAAP rents under expiring leases. Annualized rental revenues from second generation leases expiring during any particular year are typically less than 15% of our total annual rental revenues. The following table sets forth information regarding second generation office leases signed during the second quarter of 2018 (we define second generation office leases as leases with new customers and renewals of existing customers in office space that has been previously occupied under our ownership and leases with respect to vacant space in acquired buildings):

	New			Renewal			All Office
Leased space (in rentable square feet)	188,522			928,472			1,116,994
Average term (in years - rentable square foot weighted)	6.7			6.7			6.7
Base rents (per rentable square foot) (1)	$	28.91		$	27.23		$	27.51
Rent concessions (per rentable square foot) (1)	(0.77		)	(0.50		)	(0.55		)
GAAP rents (per rentable square foot) (1)	$	28.14		$	26.73		$	26.96
Tenant improvements (per rentable square foot) (1)	$	4.41		$	2.12		$	2.51
Leasing commissions (per rentable square foot) (1)	$	1.06		$	0.56		$	0.64

__________

(1) Weighted average per rentable square foot on an annual basis over the lease term.

Annual combined GAAP rents for new and renewal leases signed in the second quarter were $26.96 per rentable square foot, or 18.2%, higher compared to previous leases in the same office spaces.

28

We strive to maintain a diverse, stable and creditworthy customer base. We have an internal guideline whereby customers that account for more than 3% of our revenues are periodically reviewed with the Company's Board of Directors. As of June 30, 2018, no customer accounted for more than 3% of our cash revenues other than the Federal Government, which accounted for 5% of our cash revenues on an annualized basis. Upon completion of the MetLife III development project in Raleigh, which is scheduled for delivery in the second quarter of 2019, it is expected that MetLife will account for approximately 3.5% of our revenues based on annualized cash revenues for June 2018.

Expenses

Our expenses primarily consist of rental property expenses, depreciation and amortization, general and administrative expenses and interest expense. From time to time, expenses also include impairments of real estate assets. Rental property expenses are expenses associated with our ownership and operation of rental properties and include expenses that vary somewhat proportionately to occupancy levels, such as janitorial services and utilities, and expenses that do not vary based on occupancy, such as property taxes and insurance. Depreciation and amortization is a non-cash expense associated with the ownership of real property and generally remains relatively consistent each year, unless we buy, place in service or sell assets, since our properties and related building and tenant improvement assets are depreciated on a straight-line basis over fixed lives. General and administrative expenses consist primarily of management and employee salaries and benefits, corporate overhead and short and long-term incentive compensation.

Net Operating Income

Whether or not we record increasing same property net operating income (“NOI”) depends upon our ability to garner higher rental revenues, whether from higher average occupancy, higher GAAP rents per rentable square foot or higher cost recovery income, that exceed any corresponding growth in operating expenses. Same property NOI was relatively unchanged in the second quarter of 2018 as compared to 2017 due to an increase in same property revenues of $1.3 million offset by an increase of $1.2 million in same property expenses. We expect same property NOI to be higher in the remainder of 2018 as compared to 2017 as higher rental revenues, mostly from higher average GAAP rents per rentable square foot and higher parking income, are expected to more than offset lower expected average occupancy and an anticipated increase in same property operating expenses.

In addition to the effect of same property NOI, whether or not NOI increases depends upon whether the NOI from our acquired properties and development properties placed in service exceeds the NOI from sold properties. NOI was $0.7 million, or 0.6%, higher in the second quarter of 2018 as compared to 2017 due to the impact of development properties placed in service and a restoration fee, offset by NOI lost from sold properties. We expect NOI to remain relatively consistent for the remainder of 2018 as compared to 2017.

Cash Flows

In calculating net cash related to operating activities, depreciation and amortization, which are non-cash expenses, are added back to net income. We have historically generated a positive amount of cash from operating activities. From period to period, cash flow from operations depends primarily upon changes in our net income, as discussed more fully below under “Results of Operations,” changes in receivables and payables and net additions or decreases in our overall portfolio.

Net cash related to investing activities generally relates to capitalized costs incurred for leasing and major building improvements and our acquisition, development, disposition and joint venture activity. During periods of significant net acquisition and/or development activity, our cash used in such investing activities will generally exceed cash provided by investing activities, which typically consists of cash received upon the sale of properties and distributions from our joint ventures.

Net cash related to financing activities generally relates to distributions, incurrence and repayment of debt, and issuances, repurchases or redemptions of Common Stock, Common Units and Preferred Stock. We use a significant amount of our cash to fund distributions. Whether or not we have increases in the outstanding balances of debt during a period depends generally upon the net effect of our acquisition, disposition, development and joint venture activity. We generally use our revolving credit facility for daily working capital purposes, which means that during any given period, in order to minimize interest expense, we may record significant repayments and borrowings under our revolving credit facility.

Liquidity and Capital Resources

We intend to maintain a conservative and flexible balance sheet with access to multiple sources of debt and equity capital and sufficient availability under our revolving credit facility that allows us to capitalize on favorable development and acquisition opportunities as they arise.

29

Rental and other revenues are our principal source of funds to meet our short-term liquidity requirements. Other sources of funds for short-term liquidity needs include available working capital and borrowings under our revolving credit facility, which had $463.6 million of availability at July 17, 2018. Our short-term liquidity requirements primarily consist of operating expenses, interest and principal amortization on our debt, distributions and capital expenditures, including building improvement costs, tenant improvement costs and lease commissions. Building improvements are capital costs to maintain or enhance existing buildings not typically related to a specific customer. Tenant improvements are the costs required to customize space for the specific needs of customers. We anticipate that our available cash and cash equivalents and cash provided by operating activities and planned financing activities, including borrowings under our revolving credit facility, will be adequate to meet our short-term liquidity requirements. We use our revolving credit facility for working capital purposes and for the short-term funding of our development and acquisition activity and, in certain instances, the repayment of other debt. The continued ability to borrow under the revolving credit facility allows us to quickly capitalize on strategic opportunities at short-term interest rates.

Our long-term liquidity uses generally consist of the retirement or refinancing of debt upon maturity, funding of building improvements, new building developments and land infrastructure projects and funding acquisitions of buildings and development land. Our expected future capital expenditures for started and/or committed new development projects were approximately $368 million at June 30, 2018. Additionally, we may, from time to time, retire some or all of our remaining outstanding Preferred Stock and/or unsecured debt securities through redemptions, open market repurchases, privately negotiated acquisitions or otherwise.

We expect to meet our long-term liquidity needs through a combination of:

• cash flow from operating activities;

• bank term loans and borrowings under our revolving credit facility;

• the issuance of unsecured debt;

• the issuance of secured debt;

• the issuance of equity securities by the Company or the Operating Partnership; and

• the disposition of non-core assets.

At June 30, 2018, our leverage ratio, as measured by the ratio of our mortgages and notes payable and outstanding preferred stock to the undepreciated book value of our assets, was 35.3% and there were 106.3 million diluted shares of Common Stock outstanding.

For a discussion regarding dividends and distributions, see "Liquidity and Capital Resources - Dividends and Distributions."

Investment Activity

As noted above, a key tenet of our strategic plan is to continuously upgrade the quality of our office portfolio through acquisitions, dispositions and development. We generally seek to acquire and develop office buildings that improve the average quality of our overall portfolio and deliver consistent and sustainable value for our stockholders over the long-term. Whether or not an asset acquisition or new development results in higher per share net income or funds from operations ("FFO") in any given period depends upon a number of factors, including whether the NOI for any such period exceeds the actual cost of capital used to finance the acquisition or development. Additionally, given the length of construction cycles, development projects are not placed in service until, in some cases, several years after commencement. Sales of non-core assets could result in lower per share net income or FFO in any given period in the event the resulting use of proceeds does not exceed the capitalization rate on the sold properties.

Results of Operations

Three Months Ended June 30, 2018 and 2017

Rental and Other Revenues

Rental and other revenues were $1.5 million, or 0.9%, higher in the second quarter of 2018 as compared to 2017 primarily due to development properties placed in service, a restoration fee and higher same property revenues, which increased rental and

30

other revenues by $3.3 million, $1.9 million and $1.3 million, respectively. Same property rental and other revenues were higher primarily due to higher average GAAP rents per rentable square foot and higher cost recovery income, partly offset by lower average occupancy. These increases were partly offset by lost revenue of $4.6 million from property dispositions. We expect rental and other revenues to be higher for the remainder of 2018 as compared to 2017 due to development properties placed in service and higher same property revenues, partly offset by lost revenue from property dispositions.

Operating Expenses

Rental property and other expenses were $0.8 million, or 1.4%, higher in the second quarter of 2018 as compared to 2017 primarily due to development properties placed in service and higher same property operating expenses, which increased operating expenses by $1.4 million and $1.2 million, respectively. Same property operating expenses were higher primarily due to higher contract services, repairs and maintenance and property taxes, partly offset by lower utilities. These increases were partly offset by a $1.8 million decrease in operating expenses from property dispositions. We expect rental property and other expenses to be higher for the remainder of 2018 as compared to 2017 due to higher same property operating expenses and development properties placed in service, partly offset by lower operating expenses due to property dispositions.

Depreciation and amortization was $0.9 million, or 1.6%, higher in the second quarter of 2018 as compared to 2017 primarily due to development properties placed in service, partly offset by property dispositions. We expect depreciation and amortization to be lower for the remainder of 2018 as compared to 2017 due to fully amortized acquisition-related intangible assets and property dispositions, partly offset by development properties placed in service.

General and administrative expenses were $0.5 million, or 5.4%, higher in the second quarter of 2018 as compared to 2017 primarily due to higher company-wide base salaries and expensed pre-development costs. We expect general and administrative expenses to be similar for the remainder of 2018 as compared to 2017 as higher company-wide base salaries and benefits are expected to be offset by lower incentive compensation.

Interest Expense

Interest expense was $1.7 million, or 10.7%, higher in the second quarter of 2018 as compared to 2017 primarily due to lower capitalized interest, higher average debt balances and higher average interest rates. We expect interest expense to be higher for the remainder of 2018 as compared to 2017 due to higher average debt balances, partly offset by lower average interest rates and higher capitalized interest.

Other Income

Other income was $0.9 millionlower in the second quarter of 2018 as compared to 2017 primarily due to gains on debt extinguishment in 2017.

Gains on Disposition of Property

Gains on disposition of property were $17.0 millionhigher in the second quarter of 2018 as compared to 2017 due to no disposition activity in 2017.

Equity in Earnings of Unconsolidated Affiliates

Equity in earnings of unconsolidated affiliates was $0.2 million, or 27.7%, lower in the second quarter of 2018 as compared to 2017 primarily due to our share of the net effect of the disposition activity by certain unconsolidated affiliates in 2017 and lower average occupancy. We expect equity in earnings of unconsolidated affiliates to be lower for the remainder of 2018 as compared to 2017 due to our share of the net effect of the disposition activity in 2017.

Earnings Per Common Share - Diluted

Diluted earnings per common share was $0.12higher in the second quarter of 2018 as compared to 2017 due to an increase in net income for the reasons discussed above, partly offset by an increase in the weighted average Common Shares outstanding.

31

Six Months Ended June 30, 2018 and 2017

Rental and Other Revenues

Rental and other revenues were $12.5 million, or 3.6%, higher in the first six months of2018 as compared to 2017 primarily due to development properties placed in service, higher same property revenues and a restoration fee, which increased rental and other revenues by $11.8 million, $5.9 million and $3.8 million, respectively. Same property rental and other revenues were higher primarily due to higher average GAAP rents per rentable square foot, higher cost recovery income and higher termination fees, partly offset by lower average occupancy. These increases were partly offset by lost revenue of $8.6 million from property dispositions.

Operating Expenses

Rental property and other expenses were $2.8 million, or 2.4%, higher in the first six months of2018 as compared to 2017 primarily due to development properties placed in service and higher same property operating expenses, which increased operating expenses by $3.3 million and $2.9 million, respectively. Same property operating expenses were higher primarily due to higher contract services, repairs and maintenance and property taxes. These increases were partly offset by a $3.5 million decrease in operating expenses from property dispositions.

Depreciation and amortization was $2.3 million, or 2.1%, higher in the first six months of2018 as compared to 2017 primarily due to development properties placed in service and higher same property lease-related depreciation and amortization, partly offset by property dispositions and accelerated depreciation in 2017 related to properties that are expected to be demolished.

General and administrative expenses were $0.8 million, or 3.8%, higher in the first six months of2018 as compared to 2017 primarily due to higher company-wide base salaries and long-term equity incentive compensation.

Interest Expense

Interest expense was $2.3 million, or 6.6%, higher in the first six months of2018 as compared to 2017 primarily due to lower capitalized interest, partly offset by lower average debt balances and lower average interest rates.

Other Income

Other income was $1.2 millionlower in the first six months of2018 as compared to 2017 primarily due to gains on debt extinguishment in 2017 and lower income from deferred compensation plan investments in 2018.

Gains on Disposition of Property

Gains on disposition of property were $11.6 millionhigher in the first six months of2018 as compared to 2017 due to the net effect of the disposition activity in such periods.

Equity in Earnings of Unconsolidated Affiliates

Equity in earnings of unconsolidated affiliates was $0.6 million, or 37.5%, lower in the first six months of2018 as compared to 2017 primarily due to our share of the net effect of the disposition activity by certain unconsolidated affiliates in 2017 and lower average occupancy.

Earnings Per Common Share - Diluted

Diluted earnings per common share was $0.12higher in the first six months of2018 as compared to 2017 due to an increase in net income for the reasons discussed above, partly offset by an increase in the weighted average Common Shares outstanding.

Liquidity and Capital Resources

Statements of Cash Flows

We report and analyze our cash flows based on operating activities, investing activities and financing activities. The following table sets forth the changes in the Company’s cash flows ($ in thousands):

	Six Months Ended June 30,
	2018			2017			Change
Net Cash Provided By Operating Activities	$	183,958		$	172,115		$	11,843
Net Cash Used In Investing Activities	(201,839		)	(165,156		)	(36,683		)
Net Cash Used In Financing Activities	(60,534		)	(51,632		)	(8,902		)
Total Cash Flows	$	(78,415	)	$	(44,673	)	$	(33,742	)

The increase in net cash provided by operating activities in the first six months of2018 as compared to 2017 was primarily due to higher net cash from the operations of development properties placed in service and same properties and the timing of cash paid for operating expenses. We expect net cash related to operating activities for the remainder of 2018 to be higher as compared to 2017 primarily due to the impact of development properties placed in service, partly offset by non-core dispositions.

The increase in net cash used in investing activities in the first six months of2018 as compared to 2017 was primarily due to acquisition activity in 2018, partly offset by higher net proceeds from disposition activity in 2018. We expect uses of cash for investing activities for the remainder of 2018 to be primarily driven by whether or not we acquire and commence development of additional office buildings in the BBDs of our markets. Additionally, as of June 30, 2018, we have approximately $368 million left to fund of our previously-announced development activity in 2018 and future years. We expect these uses of cash for investing activities will be partly offset by proceeds from non-core dispositions for the remainder of 2018.

The increase in net cash used in financing activities in the first six months of2018 as compared to 2017 was primarily due to higher proceeds from the issuance of Common Stock in 2017 and higher net debt borrowings in 2017, partly offset by the payment of a special dividend in 2017. Assuming the net effect of our acquisition, disposition and development activity in 2018 results in an increase of our assets, we would expect outstanding debt and/or Common Stock balances to increase.

Capitalization

The following table sets forth the Company’s capitalization (in thousands, except per share amounts):

	June 30, 2018		December 31, 2017
Mortgages and notes payable, net, at recorded book value	$	2,055,004	$	2,014,333
Preferred Stock, at liquidation value	$	28,887	$	28,892
Common Stock outstanding	103,459		103,267
Common Units outstanding (not owned by the Company)	2,806		2,829
Per share stock price at period end	$	50.73	$	50.91
Market value of Common Stock and Common Units	$	5,390,823	$	5,401,347
Total capitalization	$	7,474,714	$	7,444,572

At June 30, 2018, our mortgages and notes payable and outstanding preferred stock represented 27.9% of our total capitalization and 35.3% of the undepreciated book value of our assets. See also "Executive Summary - Liquidity and Capital Resources."

Our mortgages and notes payable as of June 30, 2018 consisted of $98.1 million of secured indebtedness with a weighted average interest rate of 4.0% and $1,967.1 million of unsecured indebtedness with a weighted average interest rate of 3.45%. The secured indebtedness was collateralized by real estate assets with an aggregate undepreciated book value of $147.4 million. As of June 30, 2018, $502.0 million of our debt does not bear interest at fixed rates or is not protected by interest rate hedge contracts.

33

Investment Activity

In the normal course of business, we regularly evaluate potential acquisitions. As a result, from time to time, we may have one or more potential acquisitions under consideration that are in varying stages of evaluation, negotiation or due diligence, including potential acquisitions that are subject to non-binding letters of intent or enforceable contracts. Consummation of any transaction is subject to a number of contingencies, including the satisfaction of customary closing conditions. No assurances can be provided that we will acquire any properties in the future. See "Item 1A. Risk Factors - Recent and future acquisitions and development properties may fail to perform in accordance with our expectations and may require renovation and development costs exceeding our estimates" in our 2017 Annual Report on Form 10-K.

During the second quarter of 2018, we sold a building and various land parcels for an aggregate sale price of $34.0 million and recorded aggregate gains on disposition of property of $17.0 million.

As of June 30, 2018, we were developing 1.3 million rentable square feet of office properties. The following table summarizes these announced and in-process office developments:

Property	Market	Rentable Square Feet	Anticipated Total Investment (1)		Investment As Of June 30, 2018 (1)		Pre Leased %		Estimated Completion	Estimated Stabilization

__________

(1) Includes deferred lease commissions which are classified in deferred leasing costs on our Consolidated Balance Sheets.

(2) Recorded on our Consolidated Balance Sheets in land held for development, not development in-process.

Financing Activity

We have entered into separate equity distribution agreements with each of Wells Fargo Securities, LLC, Robert W. Baird & Co. Incorporated, BB&T Capital Markets, a division of BB&T Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, BTIG, LLC, Capital One Securities, Inc., Fifth Third Securities, Inc., Jefferies LLC and J.P. Morgan Securities LLC. Under the terms of the equity distribution agreements, the Company may offer and sell up to $300.0 million in aggregate gross sales price of shares of Common Stock from time to time through such firms, acting as agents of the Company or as principals. Sales of the shares, if any, may be made by means of ordinary brokers’ transactions on the New York Stock Exchange or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices or as otherwise agreed with any of such firms.

Our $600.0 million unsecured revolving credit facility is scheduled to mature in January 2022 and includes an accordion feature that allows for an additional $400.0 million of borrowing capacity subject to additional lender commitments. Assuming no defaults have occurred, we have an option to extend the maturity for two additional six-month periods. The interest rate at our current credit ratings is LIBOR plus 100 basis points and the annual facility fee is 20 basis points. The interest rate and facility fee are based on the higher of the publicly announced ratings from Moody's Investors Service or Standard & Poor's Ratings Services. There was $142.0 million and $136.0 million outstanding under our revolving credit facility at June 30, 2018 and July 17, 2018, respectively. At both June 30, 2018 and July 17, 2018, we had $0.4 million of outstanding letters of credit, which reduces the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility at June 30, 2018 and July 17, 2018 was $457.6 million and $463.6 million, respectively.

During the second quarter of 2018, we paid off at maturity $200.0 million principal amount of 7.5% unsecured notes.

34

During the second quarter of 2018, we entered into $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 2.91% with respect to a planned issuance of debt securities by the Operating Partnership expected to occur prior to June 11, 2019. The counterparties under our swaps are major financial institutions.

We are currently in compliance with financial covenants and other requirements with respect to our consolidated debt. Although we expect to remain in compliance with these covenants and ratios for at least the next year, depending upon our future operating performance, property and financing transactions and general economic conditions, we cannot assure you that we will continue to be in compliance.

Our revolving credit facility and bank term loans require us to comply with customary operating covenants and various financial requirements. Upon an event of default on the revolving credit facility, the lenders having at least 51.0% of the total commitments under the revolving credit facility can accelerate all borrowings then outstanding, and we could be prohibited from borrowing any further amounts under our revolving credit facility, which would adversely affect our ability to fund our operations. In addition, certain of our unsecured debt agreements contain cross-default provisions giving the unsecured lenders the right to declare a default if we are in default under more than $30.0 million with respect to other loans in some circumstances.

The indenture that governs the Operating Partnership's outstanding unsecured notes requires us to comply with customary operating covenants and various financial ratios. The trustee or the holders of at least 25.0% in principal amount of any series of notes can accelerate the principal amount of such series upon written notice of a default that remains uncured after 60 days.

We may not be able to repay, refinance or extend any or all of our debt at maturity or upon any acceleration. If any refinancing is done at higher interest rates, the increased interest expense could adversely affect our cash flow and ability to pay distributions. Any such refinancing could also impose tighter financial ratios and other covenants that restrict our ability to take actions that could otherwise be in our best interest, such as funding new development activity, making opportunistic acquisitions, repurchasing our securities or paying distributions.

Dividends and Distributions

To maintain its qualification as a REIT, the Company must pay dividends to stockholders that are at least 90.0% of its annual REIT taxable income, excluding net capital gains. The partnership agreement requires the Operating Partnership to distribute at least enough cash for the Company to be able to pay such dividends. The Company's REIT taxable income, as determined by the federal tax laws, does not equal its net income under accounting principles generally accepted in the United States of America (“GAAP”). In addition, although capital gains are not required to be distributed to maintain REIT status, capital gains, if any, are subject to federal and state income tax unless such gains are distributed to stockholders.

Cash dividends and distributions reduce the amount of cash that would otherwise be available for other business purposes, including reducing debt or funding future growth initiatives. The amount of future distributions that will be made is at the discretion of the Company's Board of Directors. For a discussion of the factors that will affect such cash flows and, accordingly, influence the decisions of the Company’s Board of Directors regarding dividends and distributions, see "Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities" in our 2017 Annual Report on Form 10-K.

During the second quarter of 2018, the Company declared and paid a cash dividend of $0.4625 per share of Common Stock.

Current and Future Cash Needs

We anticipate that our available cash and cash equivalents, cash flows from operating activities and other available financing sources, including the issuance of debt securities by the Operating Partnership, the issuance of secured debt, bank term loans, borrowings under our revolving credit facility, the issuance of equity securities by the Company or the Operating Partnership and the disposition of non-core assets, will be adequate to meet our short-term liquidity requirements.

We had $4.2 million of cash and cash equivalents as of June 30, 2018. The unused capacity of our revolving credit facility at June 30, 2018 and July 17, 2018 was $457.6 million and $463.6 million, respectively, excluding an accordion feature that allows for an additional $400.0 million of borrowing capacity subject to additional lender commitments.

We have a currently effective automatic shelf registration statement on Form S-3 with the SEC pursuant to which, at any time and from time to time, in one or more offerings on an as-needed basis, the Company may sell an indefinite amount of common stock, preferred stock and depositary shares and the Operating Partnership may sell an indefinite amount of debt securities, subject to our ability to effect offerings on satisfactory terms based on prevailing market conditions.

35

The Company from time to time enters into equity distribution agreements with a variety of firms pursuant to which the Company may offer and sell shares of common stock from time to time through such firms, acting as agents of the Company or as principals. Sales of the shares, if any, may be made by means of ordinary brokers’ transactions on the NYSE or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices or as otherwise agreed with any of such firms (which may include block trades).

During the remainder of 2018, we also expect to sell an additional $30 million to $105 million of properties no longer considered to be core assets due to location, age, quality and/or overall strategic fit. We can make no assurance, however, that we will sell any non-core assets or, if we do, what the timing or terms of any such sale will be.

Critical Accounting Estimates

There were no changes made by management to the critical accounting policies in the six months endedJune 30, 2018 other than the new revenue recognition standard adoption effective January 1, 2018. For a description of our critical accounting estimates, see “Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Estimates” in our 2017 Annual Report on Form 10-K.

Non-GAAP Information

The Company believes that FFO, FFO available for common stockholders and FFO available for common stockholders per share are beneficial to management and investors and are important indicators of the performance of any equity REIT. Because these FFO calculations exclude such factors as depreciation, amortization and impairments of real estate assets and gains or losses from sales of operating real estate assets, which can vary among owners of identical assets in similar conditions based on historical cost accounting and useful life estimates, they facilitate comparisons of operating performance between periods and between other REITs. Management believes that historical cost accounting for real estate assets in accordance with GAAP implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values have historically risen or fallen with market conditions, management believes the use of FFO, FFO available for common stockholders and FFO available for common stockholders per share, together with the required GAAP presentations, provides a more complete understanding of the Company's performance relative to its competitors and a more informed and appropriate basis on which to make decisions involving operating, financing and investing activities.

FFO, FFO available for common stockholders and FFO available for common stockholders per share are non-GAAP financial measures and therefore do not represent net income or net income per share as defined by GAAP. Net income and net income per share as defined by GAAP are the most relevant measures in determining the Company's operating performance because these FFO measures include adjustments that investors may deem subjective, such as adding back expenses such as depreciation, amortization and impairments. Furthermore, FFO available for common stockholders per share does not depict the amount that accrues directly to the stockholders' benefit. Accordingly, FFO, FFO available for common stockholders and FFO available for common stockholders per share should never be considered as alternatives to net income, net income available for common stockholders, or net income available for common stockholders per share as indicators of the Company's operating performance.

The Company's presentation of FFO is consistent with FFO as defined by the National Association of Real Estate Investment Trusts, which is calculated as follows:

• Net income/(loss) computed in accordance with GAAP;

• Less net income attributable to noncontrolling interests in consolidated affiliates;

• Plus depreciation and amortization of depreciable operating properties;

• Less gains, or plus losses, from sales of depreciable operating properties, plus impairments on depreciable operating properties and excluding items that are classified as extraordinary items under GAAP;

• Plus or minus our share of adjustments, including depreciation and amortization of depreciable operating properties, for unconsolidated joint venture investments (to reflect funds from operations on the same basis); and

• Plus or minus adjustments for depreciation and amortization and gains/(losses) on sales of depreciable operating properties, plus impairments on depreciable operating properties, and noncontrolling interests in consolidated affiliates related to discontinued operations.

In calculating FFO, the Company includes net income attributable to noncontrolling interests in the Operating Partnership, which the Company believes is consistent with standard industry practice for REITs that operate through an UPREIT structure.

36

The Company believes that it is important to present FFO on an as-converted basis since all of the Common Units not owned by the Company are redeemable on a one-for-one basis for shares of its Common Stock.

The following table sets forth the Company's FFO, FFO available for common stockholders and FFO available for common stockholders per share ($ in thousands, except per share amounts):

__________

(1) Includes assumed conversion of all potentially dilutive Common Stock equivalents.

In addition, the Company believes NOI and same property NOI are useful supplemental measures of the Company’s property operating performance because such metrics provide a performance measure of the revenues and expenses directly involved in owning real estate assets and a perspective not immediately apparent from net income or FFO. The Company defines NOI as rental and other revenues less rental property and other expenses. The Company defines cash NOI as NOI less lease termination fees, straight-line rent, amortization of lease incentives and amortization of acquired above and below market leases. Other REITs may use different methodologies to calculate NOI, same property NOI and cash NOI.

As of June 30, 2018, our same property portfolio consisted of 212 in-service properties encompassing 28.4 million rentable square feet that were wholly owned during the entirety of the periods presented (from January 1, 2017 to June 30, 2018). As of December 31, 2017, our same property portfolio consisted of 210 in-service properties encompassing 28.0 million rentable square feet that were wholly owned during the entirety of the periods presented (from January 1, 2016 to December 31, 2017). The change in our same property portfolio was due to the addition of one property encompassing 0.2 million rentable square feet acquired during 2016 and two newly developed properties encompassing 0.3 million rentable square feet placed in service during 2016. These additions were offset by the removal of one property encompassing 0.2 million rentable square feet that was sold during 2018.

Rental and other revenues related to properties not in our same property portfolio were $13.5 million and $13.2 million for the three months endedJune 30, 2018 and 2017, respectively, and $27.5 million and $20.8 million for the six months endedJune 30, 2018 and 2017, respectively. Rental property and other expenses related to properties not in our same property portfolio were $2.8 million and $3.3 million for the three months endedJune 30, 2018 and 2017, respectively, and $6.1 million and $6.2 million for the six months endedJune 30, 2018 and 2017, respectively.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The effects of potential changes in interest rates are discussed below. Our market risk discussion includes “forward-looking statements” and represents an estimate of possible changes in fair value or future earnings that would occur assuming hypothetical future movements in interest rates. Actual future results may differ materially from those presented. See “Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources” and the Notes to Consolidated Financial Statements for a description of our accounting policies and other information related to these financial instruments.

We borrow funds at a combination of fixed and variable rates. Borrowings under our revolving credit facility and bank term loans bear interest at variable rates. Our long-term debt, which consists of secured and unsecured long-term financings, typically bears interest at fixed rates. Our interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and lower our overall borrowing costs. To achieve these objectives, from time to time we enter into interest rate hedge contracts such as collars, swaps, caps and treasury lock agreements in order to mitigate our interest rate risk with respect to various debt instruments. We generally do not hold or issue these derivative contracts for trading or speculative purposes.

At June 30, 2018, we had $1,288.2 million principal amount of fixed rate debt outstanding, a $145.7 millionincrease as compared to December 31, 2017, excluding debt with a variable rate that is effectively fixed by related interest rate hedge contracts. The estimated aggregate fair market value of this debt was $1,258.7 million. If interest rates had been 100 basis points higher, the aggregate fair market value of our fixed rate debt would have been $72.7 million lower. If interest rates had been 100 basis points lower, the aggregate fair market value of our fixed rate debt would have been $78.8 million higher.

At June 30, 2018, we had $502.0 million of variable rate debt outstanding, a $103.0 milliondecrease as compared to December 31, 2017, not protected by interest rate hedge contracts. If the weighted average interest rate on this variable rate debt had been 100 basis points higher, the annual interest expense would increase $5.0 million. If the weighted average interest rate on this variable rate debt had been 100 basis points lower, the annual interest expense would decrease $5.0 million.

At June 30, 2018, we had $275.0 million of variable rate debt outstanding with $275.0 million of related floating-to-fixed interest rate swaps. These swaps effectively fix the underlying one-month LIBOR rate at a weighted average rate of 1.681%. If the underlying LIBOR interest rates increase or decrease by 100 basis points, the aggregate fair market value of the swaps at June 30, 2018 would increase by $2.7 million or decrease by $2.8 million, respectively.

During the second quarter of 2018, we entered into $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 2.91% with respect to a planned issuance of debt securities by the Operating Partnership expected to occur prior to June 11, 2019. If the underlying treasury rate was to increase or decrease by 100 basis points, the aggregate fair market value of the swaps at June 30, 2018 would increase by $12.3 million or decrease by $13.7 million, respectively, due to the 10-year term of such swaps.

We are exposed to certain losses in the event of nonperformance by the counterparties, which are major financial institutions, under the swaps. We regularly evaluate the financial condition of our counterparties using publicly available information. Based on this review, we currently expect the counterparties to perform fully under the swaps. However, if a counterparty defaults on its obligations under a swap, we could be required to pay the full rates on the applicable debt, even if such rates were in excess of the rate in the contract.

ITEM 4. CONTROLS AND PROCEDURES

SEC rules require us to maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our annual and periodic reports filed with the SEC 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 to allow for timely decisions regarding required disclosure. The Company's CEO and CFO have concluded that the disclosure controls and procedures of the Company and the Operating Partnership were each effective at the end of the period covered by this Quarterly Report.

SEC rules also require us to establish and maintain internal control over financial reporting designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. There were no changes in internal control over financial reporting during the three months endedJune 30, 2018 that materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting. There were also no changes in internal control over financial reporting during the three months endedJune 30, 2018 that materially affected, or are reasonably likely to materially affect, the Operating Partnership's internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

During the second quarter of 2018, the Company issued an aggregate of 4,000 shares of Common Stock to holders of Common Units in the Operating Partnership upon the redemption of a like number of Common Units in private offerings exempt from the registration requirements pursuant to Section 4(2) of the Securities Act. Each of the holders of Common Units was an accredited investor under Rule 501 of the Securities Act. The resale of such shares was registered by the Company under the Securities Act.

ITEM 5. OTHER INFORMATION

On July 19, 2018, the limited partnership agreement of the Operating Partnership was amended in response to changes to the Internal Revenue Code enacted by the Bipartisan Budget Act of 2015 (the “BBA”). Among other things, the amendment specifies that the Company, in its capacity as general partner of the Operating Partnership, shall serve as the so-called “partnership representative” under the BBA’s new partnership audit and adjustment procedures for tax years beginning in 2018.

The tax matters partner is authorized, but not required:

2

(1)to enter into any settlement with the IRS with respect to any administrative or judicial proceedings for the adjustment of Partnership items required to be taken into account by a Partner for income tax purposes (such administrative proceedings being referred to as a “tax audit” and such judicial proceedings being referred to as “judicial review”), and in the settlement agreement the tax matters partner may expressly state that such agreement shall bind all Partners, except that such settlement agreement shall not bind any Partner (i) who (within the time prescribed pursuant to the Code and Regulations) files a statement with the IRS providing that the tax matters partner shall not have the authority to enter into a settlement agreement on behalf of such Partner or (ii) who is a “notice partner” (as defined in Section 6231(a)(8) of the Code) or a member of a “notice group” (as defined in Section 6223(b)(2) of the Code);

(2)in the event that a notice of a final administrative adjustment at the Partnership level of any item required to be taken into account by a Partner for tax purposes (a “final adjustment”) is mailed to the tax matters partner, to seek judicial review of such final adjustment, including the filing of a petition for readjustment with the Tax Court or the filing of a complaint for refund with the United States Claims Court or the District Court of the United States for the district in which the Partnership’s principal place of business is located;

(3)to intervene in any action brought by any other Partner for judicial review of a final adjustment;

(4)to file a request for an administrative adjustment with the IRS and, if any part of such request is not allowed by the IRS, to file an appropriate pleading (petition or complaint) for judicial review with respect to such request;

(5)to enter into an agreement with the IRS to extend the period for assessing any tax which is attributable to any item required to be taken into account by a Partner for tax purposes, or an item affected by such item; and

(6)to take any other action on behalf of the Partners or the Partnership in connection with any tax audit or judicial review proceeding to the extent permitted by applicable law or regulations.

The taking of any action and the incurring of any expense by the tax matters partner in connection with any such proceeding, except to the extent required by law, is a matter in the sole and absolute discretion of the tax matters partner and the provisions relating to indemnification of the General Partner set forth in Section 7.7 of this Agreement shall be fully applicable to the tax matters partner in its capacity as such.

B.Designation of Partnership Representative; Scope of Duties and Authority.

(1)For tax periods for which any of the Partnership Tax Audit Rules are in effect with respect to the Partnership, the “partnership representative” (within the meaning of Section 6223(a) of the Code) (the “Partnership Representative”) of the Partnership shall be the General Partner (unless the General Partner is not authorized under the Partnership Tax Audit Rules to serve as the Partnership Representative, resigns as the Partnership Representative or is found by a court of competent

3

jurisdiction upon entry of a final judgment to have engaged in fraud, willful misconduct, or gross negligence as the Partnership Representative, in which case a Person so authorized and selected by the Partners in accordance with Section 14.2 shall be the Partnership Representative. The Partnership Representative is authorized to and shall represent the Partnership (at the Partnership’s expense) in connection with all examinations of the Partnership’s affairs by any federal, state, or local tax authorities, including resulting administrative and judicial proceedings (each a “Tax Audit” and collectively, “Tax Audits”), and to expend Partnership funds for professional services and costs associated therewith.

(2)In its capacity as such, the Partnership Representative shall have the authority and discretion to exercise any and all authority of the Partnership Representative under the Code, including, without limitation, (i) binding the Partnership and its Partners with respect to tax matters, including, but not limited to, by entering into any settlement offer, agreeing to extend statutes of limitation, and initiating litigation and, (ii) if the IRS, in connection with a Tax Audit governed by the Partnership Tax Audit Rules, proposes a Covered Audit Adjustment, determining, in its sole discretion, whether, to the extent that such election is available under the Partnership Tax Audit Rules, to make a Push-Out Election.

(3)If the Partnership Representative changes its address, the Partnership Representative shall promptly notify the IRS of such occurrence. If the Partnership Representative is replaced pursuant to Section 10.3.B(1), the outgoing Partnership Representative shall take all actions required by the Partnership Tax Audit Rules to revoke or resign its prior designation as the Partnership Representative.

C.Election Out.

(1)To the extent that the Election Out is available to the Partnership under the Partnership Tax Audit Rules, the General Partner may make the Election Out.

(2)If the Partnership Representative makes an Election Out, the Partnership shall, within thirty (30) days of receipt of a written request, make available to any Partner, at such Partner’s expense, any information such Partner reasonably requests in connection with any Tax Audit relating to such Partner’s interest in the Partnership. Each Partner shall inform the Partnership of any Covered Audit Adjustments to Partnership items that result from any Tax Audit of such Partner within thirty (30) days of the close of such Tax Audit.

D.Push-Out Election; Imputed Underpayment Modifications.

(1)If the Partnership Representative makes a Push-Out Election with respect to a Covered Audit Adjustment, each Partner (including transferees or successors of any Partner) covenants and agrees that it shall (1) pay any and all resulting taxes, additions to tax, penalties and interest in a timely fashion and (2) cooperate with the Partnership and the Partnership Representative in good faith. Notwithstanding the foregoing, if the Partnership is required to pay any tax, addition to tax, penalty, or interest following a Push-Out Election because any portion of the applicable Covered Audit Adjustment would otherwise be subject to withholding by the Partnership under Chapters 3 or 4 of Subtitle A of the Code, any such amounts shall be considered

4

Partnership Level Taxes with respect to the applicable Partners subject to the provisions of Section 10.5.

(2)To the extent that the Partnership Representative does not make a Push-Out Election with respect to a Covered Audit Adjustment, the Partnership Representative may make Imputed Underpayment Modifications (taking into account whether the Partnership Representative has received all requisite information on a timely basis from the Partners), and each Partner shall, as requested by the Partnership Representative, take such actions as may be necessary or prudent for the Partnership Representative to seek an Imputed Underpayment Modification (including, for the avoidance of doubt, filing an amended federal income tax return or following an alternative procedure to filing an amended federal income tax return, as described in Section 6225(c)(2) of the Code, paying any and all resulting federal income taxes in a timely fashion, providing all necessary information to the Partnership to support the modification of the tax rate applicable to any Imputed Underpayment Modification pursuant to Section 6225(c)(4) of the Code, and providing an affidavit to the Partnership Representative that such actions have been taken). If not otherwise sought by the Partnership Representative and if reasonably requested by a Partner, the Partnership Representative shall use commercially reasonable efforts to provide to such Partner information allowing such Partner to file an amended federal income tax return or to follow an alternative procedure to filing an amended federal income tax return, as described in Section 6225(c)(2) of the Code, to the extent that such amended return or alternative procedure and payment of any related taxes, additions to tax, penalties, and interest would reduce any Partnership Level Taxes attributable to the Covered Audit Adjustment.

(3)To the extent that the Partnership Representative does not make a Push-Out Election with respect to a Covered Audit Adjustment, the Partnership Representative is authorized, pursuant to Section 7.1, to obtain a loan on behalf of the Partnership to pay any Partnership Level Taxes.

E.Cooperation. Each Partner agrees to cooperate with the Partnership Representative and to do or refrain from doing any or all things reasonably requested by the Partnership Representative in connection with any Tax Audit. If reasonably requested by the Partnership Representative, each Partner shall deliver to the Partnership Representative: (i) any certificates, forms, affidavits, or instruments reasonably requested by the Partnership Representative relating to such Partner’s status under any tax laws, (including, but limited to, evidence of the filing of tax returns and/or payment of tax and an affirmative statement that such Partner’s tax status does not make the Partnership ineligible for an Election Out), and (ii) any information reasonably requested by the Partnership Representative in connection with the Partnership Tax Audit Rules (including, but not limited to, upper-tier shareholder specific information if a Partner is or becomes an S corporation for federal income tax purposes, upper-tier partner specific information if a Partner is or becomes a partnership for federal income tax purposes, tax returns, information regarding the character of income as capital gain or qualified dividend income, and information regarding passive activity losses).

F.Indemnification. To the maximum extent permitted by applicable law, the Partnership Representative will not be liable for, and will be indemnified and held harmless by the Partnership from and against, any and all loss, liability, damage, cost or expense, including reasonable attorneys’ and accountants’ fees, suffered or incurred in defense of any

demands, claims or lawsuits against the Partnership Representative in or as a result of or relating to his or its capacity, actions or omissions as the Partnership Representative, or concerning the Partnership or any activities undertaken on behalf of the Partnership; provided that the acts or omissions of the Partnership Representative are not found by a court of competent jurisdiction upon entry of a final judgment to have been the result of fraud or willful misconduct or, with respect to criminal matters, that the Partnership Representative had reason to believe that his conduct was unlawful.

G.Miscellaneous.

(1)Notwithstanding anything herein to the contrary, nothing in this Agreement shall obligate the Partnership Representative to provide notice to the Partners regarding any Tax Audit other than as required by the Partnership Tax Audit Rules. The Partners shall have no right to participate in any Tax Audit, unless the Partnership Representative gives its written consent otherwise.

(2)Each Partner agrees to promptly update and supplement its contact information as necessary to keep such information up-to-date, even if such Partner’s interest in the Partnership is transferred or terminated.

(3)The provisions of this Section 10.3, including the Partnership Representative’s authority under this Section 10.3, shall survive the termination, dissolution, liquidation and winding up of the Partnership and the termination or transfer of any Partner’s interest in the Partnership and shall remain binding on each Partner for the period of time necessary to resolve any Tax Audit involving or related to the Partnership.

H.Compensation. Neither the tax matters partner nor the Partnership Representative shall receive any compensation for its services. All third-party costs and expenses incurred by the tax matters partner or the Partnership Representative in performing its duties as such (including legal and accounting fees and expenses) shall be borne by the Partnership. Nothing herein shall be construed to restrict the Partnership from engaging an accounting firm to assist the tax matters partner or Partnership Representative in discharging its duties hereunder, so long as the compensation paid by the Partnership for such services is reasonable.

6.    Amendment of Section 10.5. Section 10.5 is hereby deleted in its entirety and replaced in full as follows:

A.General Provisions Regarding Withholding and Other Tax Payments by the Partnership. Each of the Partnership and its Subsidiaries may withhold from distributions, allocations or portions thereof (1) if it is required to do so by any applicable rule, regulation or law or, (2) in its discretion, as reasonably necessary to satisfy expected future withholding tax obligations following the redemption of Partnership Units, and each Partner hereby authorizes the Partnership and its Subsidiaries to withhold or pay on behalf of or with respect to such Partner any amount of federal, state, provincial, local or foreign taxes that the General Partner determines, in good faith, that the Partnership or any of its Subsidiaries is required to withhold or pay with respect to any amount distributable or allocable to such Partner pursuant to this Agreement. To the extent that any tax is paid by the Partnership or any of its Subsidiaries and the General Partner determines, in good faith, that such tax (including any Partnership

6

Level Tax) relates to one or more specific Partners, such tax shall be treated as an amount of taxes paid with respect to such Partner pursuant to this Section 10.5. Any determinations made by the General Partner pursuant to this Section 10.5.A shall be binding upon the Partners. Notwithstanding any provision to the contrary in this Section 10.5.A, the payment by the Partnership of Partnership Level Taxes shall, consistent with the Partnership Tax Audit Rules, be treated as the payment of a Partnership obligation and shall be treated as paid with respect to a Partner to the extent the deduction with respect to such payment is allocated to such Partner pursuant to Section 6.2.C, and such payment shall not be treated as a withholding from distributions, allocations, or portions thereof with respect to a Partner.

B.Tax Treatment of Withholding and Other Tax Payments by the Partnership.

(1)Tax Offset. For all purposes under this Agreement, any amounts withheld or paid with respect to a Partner pursuant to this Section 10.5 (other than the payment of Partnership Level Taxes) may be offset against any distributions to which such Partner is entitled concurrently with such withholding or payment (a “Tax Offset”); provided that the amount of any distribution subject to a Tax Offset shall be treated as having been distributed to such Partner pursuant to Section 5.1 at the time such Tax Offset is made.

(2)Tax Contribution Obligation. To the extent that (I) the amount of such Tax Offset exceeds the distributions to which such Partner is entitled concurrently with such withholding or payment (an “Excess Tax Amount”) or (II) there is a payment of Partnership Level Taxes relating to a Partner, the amount of such (A) Excess Tax Amount or (B) Partnership Level Taxes, as applicable, shall, in the General Partner’s sole discretion, (a) give rise to an interest-bearing obligation of such Partner to make a capital contribution to the Partnership (a “Tax Contribution Obligation”) and/or (b) be offset against future distributions to which such Partner is entitled until such Excess Tax Amount or Partnership Level Taxes, as applicable and, in each case, with interest accrued thereon, is reduced to zero.

(i)If requested by the General Partner, a Partner shall promptly contribute the amount of its Tax Contribution Obligation to the Partnership. To the extent a Partner does not promptly contribute the amount of its Tax Contribution Obligation to the Partnership, the Partnership shall offset such amount (plus interest accruing at the applicable underpayment rate for such period, as specified in Section 6621 of the Code) against distributions to which such Partner would otherwise be subsequently entitled until the Partner’s Tax Contribution Obligation (including any interest accrued thereon) has been satisfied in full. For the avoidance of doubt, the interest on any Tax Contribution Obligation paid by a Partner to the Partnership (whether directly or by offset) under this Section 10.5.B shall be taxable income to the Partnership.

(ii)To the extent, and at the time(s), that a Partner makes a payment to satisfy such Partner’s Tax Contribution Obligation (including any accrued but unpaid interest thereon), such payment shall be applied first to any accrued but unpaid interest owed by such Partner, and any remaining portion shall satisfy such Partner’s Tax

7

Contribution Obligation and such remaining portion shall increase such Partner’s Capital Account but shall not reduce the amount that a Partner is otherwise obligated to contribute to the Partnership. Amounts recovered by the Partnership through any offset against distributions pursuant to this Section 10.5.B shall be applied first to any accrued but unpaid interest owed by such Partner, and thereafter offset the amount of such Partner’s Tax Contribution Obligation, and such Partner’s Capital Account shall not be reduced to the extent such offset was against the amount of such Partner’s Tax Contribution Obligation.

(3)Security Interest. Each Partner hereby unconditionally and irrevocably grants to the Partnership a security interest in such Partner’s Partnership Units to secure such Partner’s Tax Contribution Obligation. Each Partner shall take such actions as the Partnership may request in order to perfect or enforce the security interest created hereunder.

(4)Indemnification by Partner. Each Partner hereby agrees to indemnify and hold harmless the Partnership, the other Partners, the Partnership Representative and the General Partner from and against any liability (including any liability for Partnership Level Taxes) with respect to income attributable to or distributions or other payments to such Partner.

C.Continued Obligations of Former Partners. For the avoidance of doubt, any Person who ceases to be a Partner shall be deemed to be a Partner for purposes of this Section 10.5, and the obligations of a Partner pursuant to this Section 10.5 shall survive indefinitely with respect to any taxes withheld or paid by the Partnership that relate to the period during which such Person was actually a Partner, regardless of whether such taxes are assessed, withheld or otherwise paid during such period.

D.Discretion Regarding Recovery of Taxes. Notwithstanding the foregoing, the General Partner may choose to not recover an amount of Partnership Level Taxes or other taxes withheld or paid with respect to a Partner under this Section 10.5 if the General Partner determines, in its reasonable discretion, that such an decision would be in the best interests of the Partnership (e.g., where the cost of recovering the amount of taxes withheld or paid with respect to such Partner is not justified in light of the amount that may be recovered from such Partner).

7.    Entire Agreement. Together with the Partnership Agreement (and the Exhibits thereto), this Amendment contains the entire understanding and agreement among the Partners with respect to the subject matter hereof and supersedes all prior written or oral understandings or agreements among them with respect thereto.

8.    Headings. The headings of the sections of this Amendment are inserted for convenience only and shall not constitute a part hereof nor affect in any way the meaning or interpretation of this Amendment.

9.    Partnership Continuation; Partnership Agreement Ratified and Confirmed. This Amendment shall not dissolve the Partnership, and the business of the Partnership shall be deemed to have continued notwithstanding this Amendment, and notwithstanding any contrary rights and privileges which may be contained in the Partnership Agreement. Except as amended by this Amendment, the Partnership Agreement

8

is hereby ratified and confirmed in all other respects and shall otherwise remain unmodified and in full force and effect.

IN WITNESS WHEREOF, the General Partner has executed this Amendment as of the date first written above.

Description of Business

Highwoods Properties, Inc. (the “Company”) is a fully integrated real estate investment trust (“REIT”) that provides leasing, management, development, construction and other customer-related services for its properties and for third parties. The Company conducts its activities through Highwoods Realty Limited Partnership (the “Operating Partnership”). At June 30, 2018, we owned or had an interest in 30.5 million rentable square feet of in-service properties, 2.0 million rentable square feet of properties under development and approximately 400 acres of development land.

The Company is the sole general partner of the Operating Partnership. At June 30, 2018, the Company owned all of the Preferred Units and 103.1 million, or 97.4%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.8 million Common Units. During the six months endedJune 30, 2018, the Company redeemed 23,196 Common Units for a like number of shares of Common Stock.

Basis of Presentation

Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).

The Company's Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership's Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. All intercompany transactions and accounts have been eliminated.

The unaudited interim consolidated financial statements and accompanying unaudited consolidated financial information, in the opinion of management, contain all adjustments (including normal recurring accruals) necessary for a fair presentation of our financial position, results of operations and cash flows. We have condensed or omitted certain notes and other information from the interim Consolidated Financial Statements presented in this Quarterly Report as permitted by SEC rules and regulations. These Consolidated Financial Statements should be read in conjunction with our 2017 Annual Report on Form 10-K.

Use of Estimates

The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.

Insurance

Beginning in 2018, we are primarily self-insured for health care claims for eligible participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities. At June 30, 2018, a reserve of $0.7 million was recorded to cover estimated reported and unreported claims.

Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that superseded the revenue recognition requirements under previous guidance, which we adopted as of January 1, 2018. Several updates have been issued subsequently which were intended to promote a more consistent interpretation and application of the principles outlined in the ASU. The ASU requires the use of a new five-step model to recognize revenue from contracts with customers. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We are also required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In analyzing our contracts with customers, we determined that the most material potential impact from the adoption of this ASU would be in how revenue is recognized for sales of real estate with continuing involvement. Prior to the adoption of this ASU, profit for such sales transactions was recognized and then reduced by the maximum exposure to loss related to the nature of the continuing involvement at the time of sale. Upon adoption of this ASU, any continuing involvement must be analyzed as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the continuing involvement performance obligation is satisfied, the sales price allocated to it will be recognized. We had no sales of real estate with continuing involvement during the first six months of2018 or prior periods; however, we will use such methodology for any future real estate sales with continuing involvement. Our internal controls with respect to accounting for such sales have been updated accordingly. The adoption of this ASU resulted in no other changes with respect to the timing of revenue recognition or internal controls related to our other contracts with customers which include primarily management, development and construction fees and transient parking income, all of which are not material to our Consolidated Financial Statements. As such, there is no cumulative-effect adjustment from the adoption of this ASU reflected in our Consolidated Financial Statements.

The FASB issued an ASU that requires entities to show changes in total cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of period balances rather than presented as transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. We adopted the ASU as of January 1, 2018 with retrospective application to our Consolidated Statements of Cash Flows. Accordingly, our Consolidated Statements of Cash Flows present a reconciliation of the changes in cash and cash equivalents and restricted cash. The effect of the adoption resulted in an $8.5 million increase in net cash used in investing activities for the six months endedJune 30, 2017. Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as construction-related escrows, property disposition proceeds set aside and designated or intended to fund future tax-deferred exchanges of qualifying real estate investments, escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements and any deposits made with lenders to unencumber secured properties.

The FASB issued an ASU that clarifies and narrows the definition of a business used in determining whether to account for a transaction as an asset acquisition or business combination. The guidance requires evaluation of the fair value of the assets acquired to determine if it is concentrated in a single identifiable asset or a group of similar identifiable assets. If so, the transferred assets would not be a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs. We adopted the ASU prospectively as of January 1, 2018. We expect that the majority of our future acquisitions would not meet the definition of a business; therefore, the related acquisition costs would be capitalized as part of the purchase price.

The FASB issued an ASU that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance requires modification accounting if the value, vesting conditions or classification of the award changes. We adopted the ASU as of January 1, 2018 with no effect on our Consolidated Financial Statements.

1.    Description of Business and Significant Accounting Policies – Continued

The FASB issued an ASU that sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. We are continuing to refine our analysis of the impact of the guidance on our Consolidated Financial Statements and the related internal controls and have an active project team working on the evaluation and implementation of the guidance. We continue to monitor FASB activity with respect to possible amendments to this ASU, particularly the FASB’s recent vote to finalize an amendment providing an optional practical expedient to lessors that removes the requirement to separate lease and non-lease components when the pattern of recognition of those components are the same and, when combined as a single unit, those would be classified as operating leases. Should the proposed amendment be issued, we expect to elect the practical expedient as our initial analysis of our leases indicates that the pattern of recognition of our material non-lease components (primarily cost recovery income) are the same as the lease components and will not require the use of the five-step revenue recognition model discussed above. We currently believe that the adoption of the ASU will not significantly change the accounting or the related internal controls for rental and other revenues from operating leases where we are the lessor, and that such leases will be accounted for in a manner similar to existing standards with the underlying leased asset being reported and recognized as a real estate asset. In addition, the guidance requires lessors to capitalize and amortize only incremental direct leasing costs. As a result, upon the adoption of the ASU, we will no longer be able to capitalize and amortize certain leasing related costs and instead will expense these costs as incurred. We are in the process of evaluating the impact to our results of operations of expensing such costs and any necessary changes to our related internal controls. The ASU is required to be adopted in 2019 using a modified retrospective approach which requires a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Leases where we are the lessee include primarily our operating ground leases. We expect to record right of use assets and the related liabilities for certain of these ground leases. We will continue to refine our evaluation and finalize our implementation plan throughout the remainder of 2018.

The FASB issued an ASU that eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item when the hedged item affects earnings. The ASU is required to be adopted in 2019 using a modified retrospective approach. We do not expect such adoption to have a material effect on our Consolidated Financial Statements.

The FASB issued an ASU that requires, among other things, the use of a new current expected credit loss ("CECL") model in determining our allowances for doubtful accounts with respect to accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable. The CECL model requires that we estimate our lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. We will also be required to disclose information about how we developed the allowances, including changes in the factors (e.g., portfolio mix, credit trends, unemployment, gross domestic product, etc.) that influenced our estimate of expected credit losses and the reasons for those changes. We will apply the ASU’s provisions as a cumulative-effect adjustment to retained earnings upon adoption in 2020. We are in the process of evaluating this ASU.

Total mortgages and notes payable, net	$	2,055,004		$	2,014,333

At June 30, 2018, our secured mortgage loans were collateralized by real estate assets with an aggregate undepreciated book value of $147.4 million.

Our $600.0 million unsecured revolving credit facility is scheduled to mature in January 2022 and includes an accordion feature that allows for an additional $400.0 million of borrowing capacity subject to additional lender commitments. Assuming no defaults have occurred, we have an option to extend the maturity for two additional six-month periods. The interest rate at our current credit ratings is LIBOR plus 100 basis points and the annual facility fee is 20 basis points. There was $142.0 million and $136.0 million outstanding under our revolving credit facility at June 30, 2018 and July 17, 2018, respectively. At both June 30, 2018 and July 17, 2018, we had $0.4 million of outstanding letters of credit, which reduces the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility at June 30, 2018 and July 17, 2018 was $457.6 million and $463.6 million, respectively.

During the second quarter of 2018, we paid off at maturity $200.0 million principal amount of 7.5% unsecured notes.

During the first quarter of 2018, the Operating Partnership issued $350.0 million aggregate principal amount of 4.125% notes due 2028, less original issuance discount of $4.1 million. These notes were priced to yield 4.271%. Underwriting fees and other expenses were incurred that aggregated $2.9 million; these costs were deferred and will be amortized over the term of the notes.

We are currently in compliance with financial covenants with respect to our consolidated debt.

We have considered our short-term liquidity needs and the adequacy of our estimated cash flows from operating activities and other available financing sources to meet these needs. We intend to meet these short-term liquidity requirements through a combination of the following:

• available cash and cash equivalents;

• cash flows from operating activities;

• issuance of debt securities by the Operating Partnership (some of which debt securities may be hedged to a fixed interest rate pursuant to the forward-starting swaps referred to in Note 6);

• issuance of secured debt;

• bank term loans;

• borrowings under our revolving credit facility;

• issuance of equity securities by the Company or the Operating Partnership; and

• the disposition of non-core assets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

During the second quarter of 2018, we entered into $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 2.91% with respect to a planned issuance of debt securities by the Operating Partnership expected to occur prior to June 11, 2019.

During 2017, we entered into $150.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at 2.44% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $350.0 million aggregate principal amount of 4.125% notes due 2028 during the first quarter of 2018, we terminated the forward-starting swaps resulting in an unrealized gain of $7.0 million in accumulated other comprehensive income and a gain of $0.2 million of hedge ineffectiveness in interest expense.

The counterparties under our swaps are major financial institutions. The swap agreements contain a provision whereby if we default on certain of our indebtedness and which default results in repayment of such indebtedness being, or becoming capable of being, accelerated by the lender, then we could also be declared in default on our swaps.

Our interest rate swaps have been designated as and are being accounted for as cash flow hedges with the effective portion of changes in fair value recorded in other comprehensive income each reporting period. No significant gain or loss was recognized related to hedge ineffectiveness or to amounts excluded from effectiveness testing on our cash flow hedges during the six months endedJune 30, 2018 and 2017. We have no collateral requirements related to our interest rate swaps.

Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our debt. During the period from July 1, 2018 through June 30, 2019, we estimate that $2.5 million will be reclassified as a decrease to interest expense.

Disclosure About Fair Value of Financial Instruments

Disclosure About Fair Value of Financial Instruments

The following summarizes the levels of inputs that we use to measure fair value.

Level 1.  Quoted prices in active markets for identical assets or liabilities.

Our Level 1 asset is our investment in marketable securities that we use to pay benefits under our non-qualified deferred compensation plan. Our Level 1 liability is our non-qualified deferred compensation obligation. The Company's Level 1 noncontrolling interests in the Operating Partnership relate to the ownership of Common Units by various individuals and entities other than the Company.

Level 2. Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.

Our Level 2 assets include the fair value of our mortgages and notes receivable and interest rate swaps. Our Level 2 liabilities include the fair value of our mortgages and notes payable.

8. Disclosure About Fair Value of Financial Instruments - Continued

The fair value of mortgages and notes receivable and mortgages and notes payable is estimated by the income approach utilizing contractual cash flows and market-based interest rates to approximate the price that would be paid in an orderly transaction between market participants. The fair value of interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments of interest rate swaps are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves. In addition, credit valuation adjustments are considered in the fair values to account for potential nonperformance risk, but were concluded to not be significant inputs to the calculation for the periods presented.

The following table sets forth our assets and liabilities and the Company's noncontrolling interests in the Operating Partnership that are measured or disclosed at fair value within the fair value hierarchy.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).

The Company's Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership's Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. All intercompany transactions and accounts have been eliminated.

The unaudited interim consolidated financial statements and accompanying unaudited consolidated financial information, in the opinion of management, contain all adjustments (including normal recurring accruals) necessary for a fair presentation of our financial position, results of operations and cash flows. We have condensed or omitted certain notes and other information from the interim Consolidated Financial Statements presented in this Quarterly Report as permitted by SEC rules and regulations. These Consolidated Financial Statements should be read in conjunction with our 2017 Annual Report on Form 10-K.

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.

Insurance

Insurance

Beginning in 2018, we are primarily self-insured for health care claims for eligible participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities. At June 30, 2018, a reserve of $0.7 million was recorded to cover estimated reported and unreported claims.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that superseded the revenue recognition requirements under previous guidance, which we adopted as of January 1, 2018. Several updates have been issued subsequently which were intended to promote a more consistent interpretation and application of the principles outlined in the ASU. The ASU requires the use of a new five-step model to recognize revenue from contracts with customers. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We are also required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In analyzing our contracts with customers, we determined that the most material potential impact from the adoption of this ASU would be in how revenue is recognized for sales of real estate with continuing involvement. Prior to the adoption of this ASU, profit for such sales transactions was recognized and then reduced by the maximum exposure to loss related to the nature of the continuing involvement at the time of sale. Upon adoption of this ASU, any continuing involvement must be analyzed as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the continuing involvement performance obligation is satisfied, the sales price allocated to it will be recognized. We had no sales of real estate with continuing involvement during the first six months of2018 or prior periods; however, we will use such methodology for any future real estate sales with continuing involvement. Our internal controls with respect to accounting for such sales have been updated accordingly. The adoption of this ASU resulted in no other changes with respect to the timing of revenue recognition or internal controls related to our other contracts with customers which include primarily management, development and construction fees and transient parking income, all of which are not material to our Consolidated Financial Statements. As such, there is no cumulative-effect adjustment from the adoption of this ASU reflected in our Consolidated Financial Statements.

The FASB issued an ASU that requires entities to show changes in total cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of period balances rather than presented as transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. We adopted the ASU as of January 1, 2018 with retrospective application to our Consolidated Statements of Cash Flows. Accordingly, our Consolidated Statements of Cash Flows present a reconciliation of the changes in cash and cash equivalents and restricted cash. The effect of the adoption resulted in an $8.5 million increase in net cash used in investing activities for the six months endedJune 30, 2017. Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as construction-related escrows, property disposition proceeds set aside and designated or intended to fund future tax-deferred exchanges of qualifying real estate investments, escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements and any deposits made with lenders to unencumber secured properties.

The FASB issued an ASU that clarifies and narrows the definition of a business used in determining whether to account for a transaction as an asset acquisition or business combination. The guidance requires evaluation of the fair value of the assets acquired to determine if it is concentrated in a single identifiable asset or a group of similar identifiable assets. If so, the transferred assets would not be a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs. We adopted the ASU prospectively as of January 1, 2018. We expect that the majority of our future acquisitions would not meet the definition of a business; therefore, the related acquisition costs would be capitalized as part of the purchase price.

The FASB issued an ASU that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance requires modification accounting if the value, vesting conditions or classification of the award changes. We adopted the ASU as of January 1, 2018 with no effect on our Consolidated Financial Statements.

1.    Description of Business and Significant Accounting Policies – Continued

The FASB issued an ASU that sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. We are continuing to refine our analysis of the impact of the guidance on our Consolidated Financial Statements and the related internal controls and have an active project team working on the evaluation and implementation of the guidance. We continue to monitor FASB activity with respect to possible amendments to this ASU, particularly the FASB’s recent vote to finalize an amendment providing an optional practical expedient to lessors that removes the requirement to separate lease and non-lease components when the pattern of recognition of those components are the same and, when combined as a single unit, those would be classified as operating leases. Should the proposed amendment be issued, we expect to elect the practical expedient as our initial analysis of our leases indicates that the pattern of recognition of our material non-lease components (primarily cost recovery income) are the same as the lease components and will not require the use of the five-step revenue recognition model discussed above. We currently believe that the adoption of the ASU will not significantly change the accounting or the related internal controls for rental and other revenues from operating leases where we are the lessor, and that such leases will be accounted for in a manner similar to existing standards with the underlying leased asset being reported and recognized as a real estate asset. In addition, the guidance requires lessors to capitalize and amortize only incremental direct leasing costs. As a result, upon the adoption of the ASU, we will no longer be able to capitalize and amortize certain leasing related costs and instead will expense these costs as incurred. We are in the process of evaluating the impact to our results of operations of expensing such costs and any necessary changes to our related internal controls. The ASU is required to be adopted in 2019 using a modified retrospective approach which requires a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. Leases where we are the lessee include primarily our operating ground leases. We expect to record right of use assets and the related liabilities for certain of these ground leases. We will continue to refine our evaluation and finalize our implementation plan throughout the remainder of 2018.

The FASB issued an ASU that eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item when the hedged item affects earnings. The ASU is required to be adopted in 2019 using a modified retrospective approach. We do not expect such adoption to have a material effect on our Consolidated Financial Statements.

The FASB issued an ASU that requires, among other things, the use of a new current expected credit loss ("CECL") model in determining our allowances for doubtful accounts with respect to accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable. The CECL model requires that we estimate our lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. We will also be required to disclose information about how we developed the allowances, including changes in the factors (e.g., portfolio mix, credit trends, unemployment, gross domestic product, etc.) that influenced our estimate of expected credit losses and the reasons for those changes. We will apply the ASU’s provisions as a cumulative-effect adjustment to retained earnings upon adoption in 2020. We are in the process of evaluating this ASU.
