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 18, 2017, 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, 2017 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, 2017, we owned or had an interest in 32.0 million rentable square feet of in-service properties, 1.2 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, 2017, the Company owned all of the Preferred Units and 102.8 million, or 97.3%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.8 million Common Units. During the six months endedJune 30, 2017, the Company redeemed 6,000 Common Units for a like number of shares of Common Stock.

Common Stock Offerings

During the first quarter of 2017, we entered into separate equity distribution agreements in which the Company may offer and sell up to $300.0 million in aggregate gross sales price of shares of Common Stock. During the three and six months endedJune 30, 2017, the Company issued 1,177,734 and 1,363,919 shares, respectively, of Common Stock under its equity distribution agreements at an average gross sales price of $51.03 and $50.85 per share, respectively, and received net proceeds, after sales commissions, of $59.2 million and $68.3 million, respectively.

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 2016 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.

1.    Description of Business and Significant Accounting Policies – Continued

Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that requires the use of a new five-step model to recognize revenue from customer contracts. 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 will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Upon adoption of the ASU in 2018, we expect to utilize the modified retrospective approach. Our initial analysis of our non-lease related revenue contracts indicates that the adoption of this ASU will impact the financial statement disclosure of these contracts with no material impact on the timing of revenue recognition; however, we are still in the process of evaluating this ASU. We expect additional impact of this ASU upon adoption of the ASU related to accounting for leases discussed below for certain lease revenue streams that will be required to be evaluated as non-lease components using the five-step revenue recognition model.

The FASB issued an ASU that adds to and clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The ASU is required to be adopted in 2018 with retrospective application required. We do not expect such adoption to have a material effect on our Consolidated Statements of Cash Flows.

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. The ASU is required to be adopted in 2018 and applied prospectively. Upon adoption of this ASU, 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. The ASU is required to be adopted in 2018 and applied prospectively. We do not expect such adoption to have a material effect on our Consolidated Financial Statements.

The FASB issued an ASU which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The ASU requires lessors to account for leases using an approach that is substantially equivalent to the existing guidance and is effective for reporting periods beginning in 2019 with early adoption permitted. Our initial analysis of our leases indicates that upon adoption of the ASU, certain lease revenue streams that are currently accounted for using the lease accounting standard will be accounted for as non-lease components using the five-step revenue recognition model discussed above. We are in the process of evaluating this ASU.

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

During the first quarter of 2017, we sold a building for a sale price of $13.0 million (before closing credits to buyer of $1.2 million) and recorded a gain on disposition of property of $5.3 million.

3.    Mortgages and Notes Receivable

Mortgages and notes receivable were $6.8 million and $8.8 million at June 30, 2017 and December 31, 2016, 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, 2017, 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, 2017			December 31, 2016
Secured indebtedness	$	99,856		$	128,204
Unsecured indebtedness	1,913,966			1,826,145
Less-unamortized debt issuance costs	(8,784		)	(6,302		)
Total mortgages and notes payable, net	$	2,005,038		$	1,948,047

At June 30, 2017, our secured mortgage loans were collateralized by real estate assets with an aggregate undepreciated book value of $147.8 million.

Our $475.0 million unsecured revolving credit facility is scheduled to mature in January 2018 and includes an accordion feature that allows for an additional $75.0 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 110 basis points and the annual facility fee is 20 basis points. There was $111.0 million and $97.0 million outstanding under our revolving credit facility at June 30, 2017 and July 18, 2017, respectively. At both June 30, 2017 and July 18, 2017, we had $0.6 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, 2017 and July 18, 2017 was $363.4 million and $377.4 million, respectively.

During the second quarter of 2017, we prepaid without penalty a secured mortgage loan with a fair market value of $108.2 million with an effective interest rate of 4.22% that was originally scheduled to mature in November 2017. We recorded $0.4 million of gain on debt extinguishment related to this prepayment.

5.    Mortgages and Notes Payable - Continued

During 2015, we acquired our joint venture partner’s 77.2% interest in a building in Orlando. Simultaneously with this acquisition, the joint venture's previously existing mortgage note was restructured into a new $18.0 million first mortgage note and a $10.2 million subordinated note, both of which were scheduled to mature in July 2017. The first mortgage and subordinated notes had effective interest rates of 5.36% and 8.6%, respectively. The subordinated note and accrued interest thereon can be satisfied, in certain circumstances, upon payment of a "waterfall payment" equal to a cash payment of 50.0% of the amount by which the net sale proceeds or appraised value at the time of refinancing exceeded (1) the outstanding principal of the first mortgage note, (2) funds deposited by us into escrow to fund tenant improvements, leasing commissions and building improvements and (3) a 10.0% return on such funds deposited by us into escrow. As of the date of such restructuring, the subordinated note was recorded at a projected waterfall payment of $1.0 million. During the second quarter of 2017, both notes were retired upon payment of the $18.0 million principal balance on the first mortgage note and a $0.5 million waterfall payment relating to the subordinated note, which resulted in $0.4 million of gain on debt extinguishment.

During the second quarter of 2017, we obtained a $100.0 million secured mortgage loan from a third party lender with an effective interest rate of 4.0%. This loan is scheduled to mature in May 2029. We incurred $0.8 million of debt issuance costs in connection with this loan, which will be amortized over the term of the loan.

During the first quarter of 2017, the Operating Partnership issued $300.0 million aggregate principal amount of 3.875% notes due 2027, less original issue discount of $4.0 million. These notes were priced to yield 4.038%. Underwriting fees and other expenses were incurred that aggregated $2.5 million; these costs were deferred and will be amortized over the term of the notes.

During the first quarter of 2017, we paid off at maturity $379.7 million principal amount of 5.85% unsecured notes.

During the first quarter of 2017, we amended our $150.0 million unsecured bank term loan that is scheduled to mature in January 2022 by increasing the borrowed amount to $200.0 million. The interest rate on this term loan at our current credit ratings is LIBOR plus 110 basis points. The underlying LIBOR rate with respect to $50.0 million of the unsecured bank term loan has been effectively fixed for the term through floating-to-fixed interest rate swaps as discussed in Note 6. We incurred $0.3 million of debt issuance costs in connection with this amendment, which will be amortized along with existing unamortized debt issuance costs over the remaining term.

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

We have considered our short-term liquidity needs within one year from July 25, 2017 (the date of issuance of the quarterly financial statements) and the adequacy of our estimated cash flows from operating activities and other expected financing sources to meet these needs. In particular, we have considered our scheduled debt maturities during such one-year period, including the $200.0 million principal amount of unsecured notes due April 15, 2018. We have concluded it is probable we will 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 2017, we entered into $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 2.44% with respect to a planned issuance of debt securities by the Operating Partnership expected to occur prior to May 15, 2018.

During the second quarter of 2017, we entered into floating-to-fixed interest rate swaps through January 2022 with respect to an aggregate of $50.0 million LIBOR-based borrowings. These swaps effectively fix the underlying one-month LIBOR rate at a weighted average rate of 1.693%.

During 2016, we entered into $150.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at 1.90% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $300.0 million aggregate principal amount of 3.875% notes due 2027 during the first quarter of 2017, we terminated the forward-starting swaps resulting in an unrealized gain of $7.3 million in accumulated other comprehensive income.

The counterparties under these 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 changes in fair value recorded in other comprehensive income/(loss) each reporting period. No 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, 2017 and 2016. We have no collateral requirements related to our interest rate swaps.

Amounts reported in accumulated other comprehensive income/(loss) related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the period from July 1, 2017 through June 30, 2018, we estimate that $0.4 million will be reclassified as a net increase to interest expense.

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

8. Disclosure About Fair Value of Financial Instruments

The following summarizes the three 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 certain interest rate swaps. Our Level 2 liabilities include the fair value of our mortgages and notes payable and remaining interest rate swaps.

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.

Level 3. Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Our Level 3 asset consisted of our tax increment financing bond, which was not routinely traded but whose fair value was determined by the income approach utilizing contractual cash flows and market-based interest rates to estimate the projected redemption value based on quoted bid/ask prices for similar unrated municipal bonds. Our tax increment financing bond was assigned in conjunction with a sale during the first quarter of 2016. The estimated fair value at the date of sale of $11.2 million was equal to the outstanding principal amount due on the bond.

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 our 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 by our competitors in our existing markets could result in an excessive supply relative to customer demand;

• our markets may suffer declines in economic 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

• the Company could lose key executive officers.

This list of risks and uncertainties, however, is not intended to be exhaustive. You should also review the other cautionary statements we make in “Business – Risk Factors” set forth in our 2016 Annual Report on Form 10-K. Given these uncertainties, you should not place undue reliance on forward-looking statements. We undertake no obligation to publicly release the results of any revisions to these forward-looking statements to reflect any future events or circumstances or to reflect the occurrence of unanticipated events.

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 employment levels in our core markets are and will continue to be important factors 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 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 2016 Annual Report on Form 10-K. Occupancy in our office portfolio was 92.9% at both December 31, 2016 and June 30, 2017 due to a development property being placed in service offset by a scheduled expiration of a large customer, both in our Nashville portfolio. We expect average occupancy for our office portfolio to be approximately 92% for the remainder of 2017.

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 2017 (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)	184,807			390,661			575,468
Average term (in years - rentable square foot weighted)	8.1			4.8			5.8
Base rents (per rentable square foot) (1)	$	29.13		$	25.77		$	26.85
Rent concessions (per rentable square foot) (1)	(0.76		)	(0.32		)	(0.46		)
GAAP rents (per rentable square foot) (1)	$	28.37		$	25.45		$	26.39
Tenant improvements (per rentable square foot) (1)	$	3.36		$	2.43		$	2.73
Leasing commissions (per rentable square foot) (1)	$	0.92		$	0.62		$	0.72

__________

(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 $26.39 per rentable square foot, or 15.1%, higher compared to previous leases in the same office spaces.

31

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, 2017, no customer accounted for more than 3% of our cash revenues other than the Federal Government, which accounted for less than 6% of our cash revenues on an annualized basis.

Operating 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 we depreciate our properties and related building and tenant improvement assets on a straight-line basis over fixed lives. General and administrative expenses consist primarily of management and employee salaries and other personnel costs, 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 from continuing operations was $2.6 million, or 2.5%, higher in the second quarter of 2017 as compared to 2016 due to an increase in same property revenues of $2.7 million. We expect same property NOI to be higher in the remainder of 2017 than 2016 as higher rental revenues, mostly from higher average GAAP rents per rentable square foot, higher cost recovery income and higher termination fees, are expected to more than offset an anticipated increase in same property operating expenses.

In addition to the effect of same property NOI, whether or not NOI from continuing operations increases depends upon whether the NOI from our acquired properties and development properties placed in service exceeds the NOI from sold properties. NOI from continuing operations was $9.1 million, or 8.3%, higher in the second quarter of 2017 as compared to 2016 due to the impact of development properties placed in service and acquisitions, offset by NOI lost from sold properties not classified as discontinued operations. We expect NOI from continuing operations to be higher in the remainder of 2017 than 2016 due to the impact of our net investment activity in such periods.

Cash Flows

In calculating net cash related to operating activities, depreciation and amortization, which are non-cash expenses, are added back to net income. As a result, 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.

32

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 $377.4 million of availability at July 18, 2017. 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 $241 million at June 30, 2017. 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.

We generally expect to grow our company on a leverage-neutral basis. At June 30, 2017, 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 106.1 million diluted shares of Common Stock outstanding.

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, 2017 and 2016

Rental and Other Revenues

Rental and other revenues were $10.4 million, or 6.2%, higher in the second quarter of 2017 as compared to 2016 primarily due to development properties placed in service, higher same property revenues and acquisitions, which increased rental and other revenues by $7.0 million, $2.7 million and $1.5 million, respectively. Same property rental and other revenues were higher primarily due to higher average GAAP rents per rentable square foot. These increases were partly offset by lost revenue of $0.6 million

33

from property dispositions. We expect rental and other revenues for the remainder of 2017 to increase over 2016 due to development properties placed in service, higher same property revenues and acquisitions, partly offset by lost revenue from property dispositions.

Operating Expenses

Rental property and other expenses were $1.3 million, or 2.3%, higher in the second quarter of 2017 as compared to 2016 primarily due to development properties placed in service and acquisitions, which increased operating expenses by $1.2 million and $0.4 million, respectively. These increases were partly offset by a $0.2 million decrease in operating expenses from property dispositions. Same property operating expenses were relatively unchanged in the second quarter of 2017 as compared to 2016. We expect rental property and other expenses for the remainder of 2017 to increase over 2016 due to development properties placed in service, higher same property operating expenses and acquisitions.

Depreciation and amortization was $0.5 million, or 0.9%, higher in the second quarter of 2017 as compared to 2016 primarily due to development properties placed in service and acquisitions, partly offset by property dispositions. We expect depreciation and amortization for the remainder of 2017 to increase over 2016 for similar reasons.

General and administrative expenses were $0.7 million, or 8.7%, higher in the second quarter of 2017 as compared to 2016 primarily due to higher company-wide base salaries, benefits and dead deal costs. We expect general and administrative expenses for the remainder of 2017 to decrease over 2016 primarily due to lower incentive compensation and acquisition costs, partly offset by higher company-wide base salaries and benefits.

Interest Expense

Interest expense was $3.3 million, or 17.1%, lower in the second quarter of 2017 as compared to 2016 primarily due to lower average debt balances, lower average interest rates and higher capitalized interest. We expect interest expense for the remainder of 2017 to remain relatively consistent with 2016.

Other Income

Other income was $0.9 millionhigher in the second quarter of 2017 as compared to 2016 primarily due to gains on debt extinguishment in 2017.

Gains on Disposition of Property

Gains on disposition of property were $5.9 millionlower in the second quarter of 2017 as compared to 2016 due to the net effect of gains on sold properties not classified as discontinued operations in 2016.

Equity in Earnings of Unconsolidated Affiliates

Equity in earnings of unconsolidated affiliates was $0.2 million, or 17.7%, lower in the second quarter of 2017 as compared to 2016 primarily due to lower occupancy in 2017. We expect equity in earnings of unconsolidated affiliates for the remainder of 2017 to decrease over 2016 primarily due to our share of the net effect of the disposition activity by certain unconsolidated affiliates in 2016 and lower occupancy in 2017.

Earnings Per Common Share - Diluted

Diluted earnings per common share was $0.05higher in the second quarter of 2017 as compared to 2016 due to an increase in net income for the reasons discussed above, partly offset by an increase in the weighted average Common Shares outstanding.

Six Months Ended June 30, 2017 and 2016

Rental and Other Revenues

Rental and other revenues were $15.0 million, or 4.5%, higher in the first six months of2017 as compared to 2016 primarily due to development properties placed in service, higher same property revenues and acquisitions, which increased rental and other revenues by $9.7 million, $4.3 million and $2.9 million, respectively. Same property rental and other revenues were higher primarily due to higher average GAAP rents per rentable square foot, partly offset by lower termination fees. These increases were partly offset by lost revenue of $1.5 million from property dispositions.

34

Operating Expenses

Rental property and other expenses were $1.2 million, or 1.0%, higher in the first six months of2017 as compared to 2016 primarily due to development properties placed in service and acquisitions, which increased operating expenses by $1.8 million and $0.8 million, respectively. These increases were partly offset by a $0.8 million decrease in same property operating expenses and a $0.5 million decrease in operating expenses from property dispositions. Same property operating expenses were lower primarily due to lower utilities and property insurance, partly offset by higher property taxes.

Depreciation and amortization was $3.2 million, or 2.9%, higher in the first six months of2017 as compared to 2016 primarily due to development properties placed in service, acquisitions and accelerated depreciation related to properties that are expected to be demolished, partly offset by property dispositions.

General and administrative expenses were $1.1 million, or 5.5%, higher in the first six months of2017 as compared to 2016 primarily due to higher company-wide base salaries, benefits and dead deal costs.

Interest Expense

Interest expense was $6.2 million, or 15.4%, lower in the first six months of2017 as compared to 2016 primarily due to lower average debt balances and higher capitalized interest.

Other Income

Other income was $1.0 millionhigher in the first six months of2017 as compared to 2016 primarily due to gains on debt extinguishment in 2017.

Gains on Disposition of Property and Net Gains on Disposition of Discontinued Operations

Total gains were $419.4 millionlower in the first six months of2017 as compared to 2016 due to the sales of substantially all of our wholly-owned Country Club Plaza assets in Kansas City (which we refer to as the “Plaza assets”) in 2016.

Equity in Earnings of Unconsolidated Affiliates

Equity in earnings of unconsolidated affiliates was $0.5 million, or 22.3%, lower in the first six months of2017 as compared to 2016 primarily due to our share of the net effect of the disposition activity by certain unconsolidated affiliates in 2016 and lower occupancy in 2017.

Income From Discontinued Operations

Income from discontinued operations was $4.1 millionlower in the first six months of2017 as compared to 2016 due to the sales of the Plaza assets in 2016.

Earnings Per Common Share - Diluted

Diluted earnings per common share was $4.10lower in the first six months of2017 as compared to 2016 due to gains from the sales of the Plaza assets in 2016 and an increase in the weighted average Common Shares outstanding, partly offset by increases in income from continuing operations for the reasons discussed above.

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,
	2017			2016			Change
Net Cash Provided By Operating Activities	$	172,115		$	137,805		$	34,310
Net Cash Provided By/(Used In) Investing Activities	(156,627		)	253,815			(410,442		)
Net Cash Used In Financing Activities	(51,632		)	(394,212		)	342,580
Total Cash Flows	$	(36,144	)	$	(2,592	)	$	(33,552	)

The increase in net cash provided by operating activities in the first six months of2017 as compared to 2016 was primarily due to higher net cash from the operations of development properties placed in service, same properties and acquisitions, the timing of cash paid for operating expenses and the settlement of cash flow hedges. We expect net cash related to operating activities for the remainder of 2017 to be higher as compared to 2016 primarily due to the impact of development properties placed in service, same properties and acquisitions, partly offset by non-core dispositions.

The change in net cash provided by/(used in) investing activities in the first six months of2017 as compared to 2016 was primarily due to the net proceeds from the sales of the Plaza assets in 2016 and higher investments in development in-process in 2017. We expect uses of cash for investing activities for the remainder of 2017 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, 2017, we have approximately $241 million left to fund of our previously-announced development activity. We expect these uses of cash for investing activities will be partly offset by proceeds from non-core dispositions for the remainder of 2017.

The decrease in net cash used in financing activities in the first six months of2017 as compared to 2016 was primarily due to higher net debt borrowings in 2017, partly offset by the payment of a special dividend declared in the fourth quarter of 2016 and lower proceeds from the issuance of Common Stock in 2017. Assuming the net effect of our acquisition, disposition and development activity in 2017 results in an increase of our assets, we would expect outstanding debt balances to increase. However, because we generally expect to grow our company on a leverage-neutral basis, we would also expect higher outstanding balances of Common Stock in such event.

Capitalization

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

	June 30, 2017		December 31, 2016
Mortgages and notes payable, net, at recorded book value	$	2,005,038	$	1,948,047
Preferred Stock, at liquidation value	$	28,905	$	28,920
Common Stock outstanding	103,236		101,666
Common Units outstanding (not owned by the Company)	2,833		2,839
Per share stock price at period end	$	50.71	$	51.01
Market value of Common Stock and Common Units	$	5,378,759	$	5,330,800
Total capitalization	$	7,412,702	$	7,307,767

At June 30, 2017, our mortgages and notes payable and outstanding preferred stock represented 27.4% 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, 2017 consisted of $99.9 million of secured indebtedness with a weighted average interest rate of 4.0% and $1,914.0 million of unsecured indebtedness with a weighted average interest rate of 3.47%. The secured indebtedness was collateralized by real estate assets with an aggregate undepreciated book value of $147.8 million. As of June 30, 2017, $596.0 million of our debt does not bear interest at fixed rates or is not protected by interest rate hedge contracts.

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 2016 Annual Report on Form 10-K.

As of June 30, 2017, we were developing 0.9 million rentable square feet of properties. The following table summarizes these announced and in-process developments:

Financing Activity

During the first quarter of 2017, we 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., Comerica Securities, Inc., Fifth Third Securities, Inc., Jefferies LLC, Morgan Stanley & Co. LLC, MUFG Securities Americas Inc. and RBC Capital Markets, 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. During the second quarter of 2017, the Company issued 1,177,734 shares of Common Stock at an average gross sales price of $51.03 per share and received net proceeds, after sales commissions, of $59.2 million. We paid an aggregate of $0.9 million in sales commissions to MUFG Securities Americas Inc., Wells Fargo Securities, LLC and Jefferies LLC during the second quarter of 2017.

During the second quarter of 2017, we prepaid without penalty a secured mortgage loan with a fair market value of $108.2 million with an effective interest rate of 4.22% that was originally scheduled to mature in November 2017. We recorded $0.4 million of gain on debt extinguishment related to this prepayment.

During 2015, we acquired our joint venture partner’s 77.2% interest in a building in Orlando. Simultaneously with this acquisition, the joint venture's previously existing mortgage note was restructured into a new $18.0 million first mortgage note and a $10.2 million subordinated note, both of which were scheduled to mature in July 2017. The first mortgage and subordinated notes had effective interest rates of 5.36% and 8.6%, respectively. The subordinated note and accrued interest thereon can be satisfied, in certain circumstances, upon payment of a "waterfall payment" equal to a cash payment of 50.0% of the amount by which the net sale proceeds or appraised value at the time of refinancing exceeded (1) the outstanding principal of the first mortgage note, (2) funds deposited by us into escrow to fund tenant improvements, leasing commissions and building improvements and (3) a 10.0% return on such funds deposited by us into escrow. As of the date of such restructuring, the subordinated note was recorded at a projected waterfall payment of $1.0 million. During the second quarter of 2017, both notes were retired upon payment

37

of the $18.0 million principal balance on the first mortgage note and a $0.5 million waterfall payment relating to the subordinated note, which resulted in $0.4 million of gain on debt extinguishment.

During the second quarter of 2017, we obtained a $100.0 million secured mortgage loan from a third party lender with an effective interest rate of 4.0%. This loan, which is secured by The Pinnacle at Symphony Place in Nashville, is scheduled to mature in May 2029. We incurred $0.8 million of debt issuance costs in connection with this loan, which will be amortized over the term of the loan.

During the second quarter of 2017, we entered into $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 2.44% with respect to a planned issuance of debt securities by the Operating Partnership expected to occur prior to May 15, 2018. During the second quarter of 2017, we also entered into floating-to-fixed interest rate swaps through January 2022 with respect to an aggregate of $50.0 million LIBOR-based borrowings, which effectively fixes the underlying one-month LIBOR rate at a weighted average rate of 1.693%. The counterparties under our swaps are major financial institutions.

Our $475.0 million unsecured revolving credit facility is scheduled to mature in January 2018 and includes an accordion feature that allows for an additional $75.0 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 110 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 $111.0 million and $97.0 million outstanding under our revolving credit facility at June 30, 2017 and July 18, 2017, respectively. At both June 30, 2017 and July 18, 2017, we had $0.6 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, 2017 and July 18, 2017 was $363.4 million and $377.4 million, respectively.

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 $25.0 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 funding debt maturities, reducing debt or 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,

38

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 2016 Annual Report on Form 10-K.

During the second quarter of 2017, the Company declared and paid a cash dividend of $0.44 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 expected 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, including the $200.0 million principal amount of unsecured notes due April 15, 2018.

We had $13.3 million of cash and cash equivalents as of June 30, 2017. The unused capacity of our revolving credit facility at June 30, 2017 and July 18, 2017 was $363.4 million and $377.4 million, respectively, excluding an accordion feature that allows for an additional $75.0 million of borrowing capacity subject to additional lender commitments. Also, we have recently demonstrated historical experience with our lending partners to obtain additional indebtedness, such as the $350.0 million, six-month unsecured bridge facility we obtained in 2015 for the short-term funding of our acquisition activity, $150.0 million unsecured term loan we obtained in 2016 (which was subsequently expanded by an additional $50.0 million in the first quarter of 2017) to repay amounts outstanding under our revolving credit facility and $100.0 million secured mortgage loan we obtained in the second quarter of 2017.

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.

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 2017, we also expect to sell $105 million to $150 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.

We generally intend to fund the growth of our company, including the $187.8 million of contractual commitments through June 30, 2018 related to our development activity, on a leverage-neutral basis. At June 30, 2017, our leverage ratio was 35.3% and there were 106.1 million diluted shares of Common Stock outstanding.

Critical Accounting Estimates

There were no changes made by management to the critical accounting policies in the six months endedJune 30, 2017. 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 2016 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. 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.

In addition, the Company believes NOI from continuing operations 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 from continuing operations, less rental property and other expenses from continuing operations. 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, 2017, our same property portfolio consisted of 224 in-service properties encompassing 29.0 million rentable square feet that were wholly owned during the entirety of the periods presented (from January 1, 2016 to June 30, 2017). As of December 31, 2016, our same property portfolio consisted of 217 in-service properties encompassing 26.7 million rentable square feet that were wholly owned during the entirety of the periods presented (from January 1, 2015 to December 31, 2016). The change in our same property portfolio was due to the addition of four properties encompassing 1.6 million rentable square feet acquired during 2015 and four newly developed properties encompassing 0.8 million rentable square feet placed in service during 2015. These additions were offset by the removal of one property encompassing 0.1 million rentable square feet that was sold during 2017.

Rental and other revenues related to properties not in our same property portfolio were $12.6 million and $4.8 million for the three months endedJune 30, 2017 and 2016, respectively, and $19.5 million and $8.8 million for the six months endedJune 30, 2017 and 2016, respectively. Rental property and other expenses related to properties not in our same property portfolio were $2.4 million and $1.1 million for the three months endedJune 30, 2017 and 2016, respectively, and $4.1 million and $2.2 million for the six months endedJune 30, 2017 and 2016, 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, 2017, we had $1,142.8 million principal amount of fixed rate debt outstanding, a $111.5 million decrease as compared to December 31, 2016, 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 $1,156.9 million. If interest rates had been 100 basis points higher, the aggregate fair market value of our fixed rate debt would have been $57.3 million lower. If interest rates had been 100 basis points lower, the aggregate fair market value of our fixed rate debt would have been $61.9 million higher.

At June 30, 2017, we had $596.0 million of variable rate debt outstanding, a $121.0 million increase as compared to December 31, 2016, 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 $6.0 million. If the weighted average interest rate on this variable rate debt had been 100 basis points lower, the annual interest expense would decrease $6.0 million.

At June 30, 2017, we had $275.0 million of variable rate debt outstanding with $275.0 million of related floating-to-fixed interest rate swaps (including $50.0 million of swaps we entered into during the second quarter of 2017). These swaps effectively fix the underlying one-month LIBOR rate at a weighted average rate of 1.681%. The weighted average rate of such swaps we held at December 31, 2016 was 1.678%. If the underlying LIBOR interest rates increase or decrease by 100 basis points, the aggregate fair market value of the swaps at June 30, 2017 would increase by $5.4 million or decrease by $5.6 million, respectively.

During the second quarter of 2017, we entered into $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 2.44% with respect to a planned issuance of debt securities by the Operating Partnership expected to occur prior to May 15, 2018. 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, 2017 would increase by $12.7 million or decrease by $14.3 million, respectively.

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.

43

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, 2017 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, 2017 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 2017, 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.

The following table sets forth information related to shares of Common Stock surrendered by employees to satisfy tax withholding obligations in connection with the vesting of restricted stock during the second quarter of 2017:

	Total Number of Shares Purchased	Weighted Average Price Paid per Share
April 1 to April 30	428	$	49.13
May 1 to May 31	141	50.97
June 1 to June 30	—	—
Total	569	$	49.59

ITEM 5. OTHER INFORMATION

As previously reported, at the Company’s annual meeting of stockholders held on May 10, 2017, a substantial majority of the holders of our common stock cast advisory votes supporting the recommendation of the Company’s Board of Directors that stockholders be provided the opportunity to cast advisory votes on our executive compensation programs every year. An advisory vote on executive compensation is referred to as a “say-on-pay vote.” In light of the Board’s recommendation and the preference of our stockholders as expressed at the annual meeting, the Company has decided to hold say-on-pay votes at its annual meeting every year.

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, 2017, we owned or had an interest in 32.0 million rentable square feet of in-service properties, 1.2 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, 2017, the Company owned all of the Preferred Units and 102.8 million, or 97.3%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.8 million Common Units. During the six months endedJune 30, 2017, the Company redeemed 6,000 Common Units for a like number of shares of Common Stock.

Common Stock Offerings

During the first quarter of 2017, we entered into separate equity distribution agreements in which the Company may offer and sell up to $300.0 million in aggregate gross sales price of shares of Common Stock. During the three and six months endedJune 30, 2017, the Company issued 1,177,734 and 1,363,919 shares, respectively, of Common Stock under its equity distribution agreements at an average gross sales price of $51.03 and $50.85 per share, respectively, and received net proceeds, after sales commissions, of $59.2 million and $68.3 million, respectively.

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 2016 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.

1.    Description of Business and Significant Accounting Policies – Continued

Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that requires the use of a new five-step model to recognize revenue from customer contracts. 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 will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Upon adoption of the ASU in 2018, we expect to utilize the modified retrospective approach. Our initial analysis of our non-lease related revenue contracts indicates that the adoption of this ASU will impact the financial statement disclosure of these contracts with no material impact on the timing of revenue recognition; however, we are still in the process of evaluating this ASU. We expect additional impact of this ASU upon adoption of the ASU related to accounting for leases discussed below for certain lease revenue streams that will be required to be evaluated as non-lease components using the five-step revenue recognition model.

The FASB issued an ASU that adds to and clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The ASU is required to be adopted in 2018 with retrospective application required. We do not expect such adoption to have a material effect on our Consolidated Statements of Cash Flows.

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. The ASU is required to be adopted in 2018 and applied prospectively. Upon adoption of this ASU, 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. The ASU is required to be adopted in 2018 and applied prospectively. We do not expect such adoption to have a material effect on our Consolidated Financial Statements.

The FASB issued an ASU which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The ASU requires lessors to account for leases using an approach that is substantially equivalent to the existing guidance and is effective for reporting periods beginning in 2019 with early adoption permitted. Our initial analysis of our leases indicates that upon adoption of the ASU, certain lease revenue streams that are currently accounted for using the lease accounting standard will be accounted for as non-lease components using the five-step revenue recognition model discussed above. We are in the process of evaluating this ASU.

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.

Mortgages and Notes Payable

The following table sets forth our mortgages and notes payable:

	June 30, 2017			December 31, 2016
Secured indebtedness	$	99,856		$	128,204
Unsecured indebtedness	1,913,966			1,826,145
Less-unamortized debt issuance costs	(8,784		)	(6,302		)
Total mortgages and notes payable, net	$	2,005,038		$	1,948,047

At June 30, 2017, our secured mortgage loans were collateralized by real estate assets with an aggregate undepreciated book value of $147.8 million.

Our $475.0 million unsecured revolving credit facility is scheduled to mature in January 2018 and includes an accordion feature that allows for an additional $75.0 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 110 basis points and the annual facility fee is 20 basis points. There was $111.0 million and $97.0 million outstanding under our revolving credit facility at June 30, 2017 and July 18, 2017, respectively. At both June 30, 2017 and July 18, 2017, we had $0.6 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, 2017 and July 18, 2017 was $363.4 million and $377.4 million, respectively.

During the second quarter of 2017, we prepaid without penalty a secured mortgage loan with a fair market value of $108.2 million with an effective interest rate of 4.22% that was originally scheduled to mature in November 2017. We recorded $0.4 million of gain on debt extinguishment related to this prepayment.

5.    Mortgages and Notes Payable - Continued

During 2015, we acquired our joint venture partner’s 77.2% interest in a building in Orlando. Simultaneously with this acquisition, the joint venture's previously existing mortgage note was restructured into a new $18.0 million first mortgage note and a $10.2 million subordinated note, both of which were scheduled to mature in July 2017. The first mortgage and subordinated notes had effective interest rates of 5.36% and 8.6%, respectively. The subordinated note and accrued interest thereon can be satisfied, in certain circumstances, upon payment of a "waterfall payment" equal to a cash payment of 50.0% of the amount by which the net sale proceeds or appraised value at the time of refinancing exceeded (1) the outstanding principal of the first mortgage note, (2) funds deposited by us into escrow to fund tenant improvements, leasing commissions and building improvements and (3) a 10.0% return on such funds deposited by us into escrow. As of the date of such restructuring, the subordinated note was recorded at a projected waterfall payment of $1.0 million. During the second quarter of 2017, both notes were retired upon payment of the $18.0 million principal balance on the first mortgage note and a $0.5 million waterfall payment relating to the subordinated note, which resulted in $0.4 million of gain on debt extinguishment.

During the second quarter of 2017, we obtained a $100.0 million secured mortgage loan from a third party lender with an effective interest rate of 4.0%. This loan is scheduled to mature in May 2029. We incurred $0.8 million of debt issuance costs in connection with this loan, which will be amortized over the term of the loan.

During the first quarter of 2017, the Operating Partnership issued $300.0 million aggregate principal amount of 3.875% notes due 2027, less original issue discount of $4.0 million. These notes were priced to yield 4.038%. Underwriting fees and other expenses were incurred that aggregated $2.5 million; these costs were deferred and will be amortized over the term of the notes.

During the first quarter of 2017, we paid off at maturity $379.7 million principal amount of 5.85% unsecured notes.

During the first quarter of 2017, we amended our $150.0 million unsecured bank term loan that is scheduled to mature in January 2022 by increasing the borrowed amount to $200.0 million. The interest rate on this term loan at our current credit ratings is LIBOR plus 110 basis points. The underlying LIBOR rate with respect to $50.0 million of the unsecured bank term loan has been effectively fixed for the term through floating-to-fixed interest rate swaps as discussed in Note 6. We incurred $0.3 million of debt issuance costs in connection with this amendment, which will be amortized along with existing unamortized debt issuance costs over the remaining term.

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

We have considered our short-term liquidity needs within one year from July 25, 2017 (the date of issuance of the quarterly financial statements) and the adequacy of our estimated cash flows from operating activities and other expected financing sources to meet these needs. In particular, we have considered our scheduled debt maturities during such one-year period, including the $200.0 million principal amount of unsecured notes due April 15, 2018. We have concluded it is probable we will 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 Financial Instruments

Derivative Financial Instruments

During the second quarter of 2017, we entered into $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 2.44% with respect to a planned issuance of debt securities by the Operating Partnership expected to occur prior to May 15, 2018.

During the second quarter of 2017, we entered into floating-to-fixed interest rate swaps through January 2022 with respect to an aggregate of $50.0 million LIBOR-based borrowings. These swaps effectively fix the underlying one-month LIBOR rate at a weighted average rate of 1.693%.

During 2016, we entered into $150.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at 1.90% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $300.0 million aggregate principal amount of 3.875% notes due 2027 during the first quarter of 2017, we terminated the forward-starting swaps resulting in an unrealized gain of $7.3 million in accumulated other comprehensive income.

The counterparties under these 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 changes in fair value recorded in other comprehensive income/(loss) each reporting period. No 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, 2017 and 2016. We have no collateral requirements related to our interest rate swaps.

Amounts reported in accumulated other comprehensive income/(loss) related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the period from July 1, 2017 through June 30, 2018, we estimate that $0.4 million will be reclassified as a net increase to interest expense.

Fair Value Disclosures [Abstract]

Disclosure About Fair Value of Financial Instruments

Disclosure About Fair Value of Financial Instruments

The following summarizes the three 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 certain interest rate swaps. Our Level 2 liabilities include the fair value of our mortgages and notes payable and remaining interest rate swaps.

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.

Level 3. Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Our Level 3 asset consisted of our tax increment financing bond, which was not routinely traded but whose fair value was determined by the income approach utilizing contractual cash flows and market-based interest rates to estimate the projected redemption value based on quoted bid/ask prices for similar unrated municipal bonds. Our tax increment financing bond was assigned in conjunction with a sale during the first quarter of 2016. The estimated fair value at the date of sale of $11.2 million was equal to the outstanding principal amount due on the bond.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation, Policy

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 2016 Annual Report on Form 10-K.

Use of Estimates, Policy

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.

Recently Issued Accounting Standards, Policy

Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that requires the use of a new five-step model to recognize revenue from customer contracts. 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 will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Upon adoption of the ASU in 2018, we expect to utilize the modified retrospective approach. Our initial analysis of our non-lease related revenue contracts indicates that the adoption of this ASU will impact the financial statement disclosure of these contracts with no material impact on the timing of revenue recognition; however, we are still in the process of evaluating this ASU. We expect additional impact of this ASU upon adoption of the ASU related to accounting for leases discussed below for certain lease revenue streams that will be required to be evaluated as non-lease components using the five-step revenue recognition model.

The FASB issued an ASU that adds to and clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The ASU is required to be adopted in 2018 with retrospective application required. We do not expect such adoption to have a material effect on our Consolidated Statements of Cash Flows.

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. The ASU is required to be adopted in 2018 and applied prospectively. Upon adoption of this ASU, 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. The ASU is required to be adopted in 2018 and applied prospectively. We do not expect such adoption to have a material effect on our Consolidated Financial Statements.

The FASB issued an ASU which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The ASU requires lessors to account for leases using an approach that is substantially equivalent to the existing guidance and is effective for reporting periods beginning in 2019 with early adoption permitted. Our initial analysis of our leases indicates that upon adoption of the ASU, certain lease revenue streams that are currently accounted for using the lease accounting standard will be accounted for as non-lease components using the five-step revenue recognition model discussed above. We are in the process of evaluating this ASU.

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.
