Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Significant Accounting Policies	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 December 31, 2019 , we owned or had an interest in 31.7 million rentable square feet of in-service properties, 1.2 million rentable square feet of office properties under development and approximately 275 acres of development land. The Company is the sole general partner of the Operating Partnership. At December 31, 2019 , the Company owned all of the Preferred Units and 103.3 million , or 97.4% , of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.7 million Common Units. In the event the Company issues shares of Common Stock, the net proceeds of the issuance are contributed to the Operating Partnership in exchange for additional Common Units. Generally, the Operating Partnership is obligated to redeem each Common Unit at the request of the holder thereof for cash equal to the value of one share of Common Stock based on the average of the market price for the 10 trading days immediately preceding the notice date of such redemption, provided that the Company, at its option, may elect to acquire any such Common Units presented for redemption for cash or one share of Common Stock. The Common Units owned by the Company are not redeemable. During 2019 , the Company redeemed 15,000 Common Units for a like number of shares of Common Stock. Basis of Presentation Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company's Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership's Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. We consolidate joint venture investments, such as interests in partnerships and limited liability companies, when we control the major operating and financial policies of the investment through majority ownership, in our capacity as a general partner or managing member or through some other contractual right. At December 31, 2019 , three properties owned through a joint venture investment were consolidated. We also consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. At December 31, 2019 , we have involvement with, and are the primary beneficiary in, an entity that we concluded to be a variable interest entity (see Note 4). In addition, during 2019, we acquired a building using a special purpose entity owned by a qualified intermediary to facilitate a potential Section 1031 reverse exchange under the Internal Revenue Code. To realize the tax deferral available under the Section 1031 exchange, we must complete the Section 1031 exchange, and take title to the to-be-exchanged building within 180 days of the acquisition date. We have determined that this entity is a variable interest entity of which we are the primary beneficiary and therefore, we consolidate this entity. As of December 31, 2019 , this variable interest entity had total assets, liabilities and cash flows of $425.0 million , $24.0 million and $2.5 million , respectively. All intercompany transactions and accounts have been eliminated. Certain amounts within the Consolidated Statements of Income for the years ended December 31, 2018 and 2017 were removed and/or combined to conform to the current year presentation. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates. Insurance We are primarily self-insured for health care claims for participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities. At December 31, 2019 , a reserve of $0.6 million was recorded to cover estimated reported and unreported claims. Other Events During the third quarter of 2019, we announced a series of planned investment activities. First, during the fourth quarter of 2019, we acquired Bank of America Tower at Legacy Union in Charlotte’s uptown CBD submarket for a total investment of $436 million . Bank of America Tower at Legacy Union is a trophy, LEED gold-registered office building encompassing 841,000 square feet with structured parking that delivered in 2019. Second, we have a two -phased plan to exit the Greensboro and Memphis markets. The first phase consists of selling a select portfolio of assets in Greensboro and Memphis by mid-2020 with a total sales price that approximates the $436 million total investment for Bank of America Tower at Legacy Union (with the intent of executing a reverse 1031 exchange) and closing the division offices. In 2020 , we sold 35 buildings and land in Greensboro for an aggregate sale price of $193.4 million . We can provide no assurances, however, that we will dispose of the remainder of these assets on favorable terms, or at all. The second phase is the planned sale of the remaining assets in both markets. There is no pre-determined timetable for the second phase. As a result of the announced plan to exit the Greensboro and Memphis markets and close our division offices, we recorded $1.8 million of severance costs in 2019. During the first quarter of 2019, Laser Spine Institute, which leased a 176,000 square foot building with structured parking in Tampa’s Westshore submarket, suddenly ceased operations. As a result of this sudden closure, we incurred $5.6 million of credit losses on operating lease receivables and $2.3 million of write-offs of lease incentives (in rental and other revenues), $4.1 million of write-offs of notes receivable (in other income/(loss)) and $11.6 million of write-offs of tenant improvements and deferred leasing costs (in depreciation and amortization). Real Estate and Related Assets Real estate and related assets are recorded at cost and stated at cost less accumulated depreciation. Renovations, replacements and other expenditures that improve or extend the life of assets are capitalized and depreciated over their estimated useful lives. Expenditures for ordinary maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful life of 40 years for buildings and depreciable land infrastructure costs, 15 years for building improvements and five to seven years for furniture, fixtures and equipment. Tenant improvements are amortized using the straight-line method over initial fixed terms of the respective leases, which generally are from three to 10 years. Depreciation expense for real estate assets was $ 214.7 million , $ 191.0 million and $ 184.4 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and are stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy and capitalize only those costs associated with the portion under construction. We record liabilities for the performance of asset retirement activities when the obligation to perform such activities is probable even when uncertainty exists about the timing and/or method of settlement. Upon the acquisition of real estate assets accounted for as asset acquisitions, we assess the fair value of acquired tangible assets such as land, buildings and tenant improvements, intangible assets and liabilities such as above and below market leases, acquired in-place leases and other identifiable intangible assets and assumed liabilities. We allocate fair value on a relative basis based on estimated cash flow projections that utilize discount and/or capitalization rates as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. The above and below market rate portions of leases acquired in connection with property acquisitions are recorded in deferred leasing costs and in accounts payable, accrued expenses and other liabilities, respectively, at fair value and amortized into rental revenue over the remaining term of the respective leases as described below. Fair value is calculated as the present value of the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) our estimate of fair market lease rates for each corresponding in-place lease, using a discount rate that reflects the risks associated with the leases acquired and measured over a period equal to the remaining initial term of the lease for above-market leases and the remaining initial term plus the term of any renewal option that the customer would be economically compelled to exercise for below-market leases. In-place leases acquired are recorded at fair value in deferred leasing costs and are amortized to depreciation and amortization expense over the remaining term of the respective lease. The value of in-place leases is based on our evaluation of the specific characteristics of each customer's lease. Factors considered include estimates of carrying costs during hypothetical expected lease-up periods, current market conditions, the customer's credit quality and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider tenant improvements, leasing commissions and legal and other related expenses. Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the sale of the asset is probable, has been duly approved by the Company, a legally enforceable contract has been executed and the buyer's due diligence period, if any, has expired. Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates With respect to assets classified as held for use, we perform an impairment analysis if our evaluation of events or changes in circumstances indicate that the carrying value may not be recoverable, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset's carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete. If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and are subject to future events that may alter our assumptions, the discounted and/or undiscounted future operating and residual cash flows estimated by us in our impairment analyses or those established by appraisal may not be achieved and we may be required to recognize future impairment losses on properties held for use. We record assets held for sale at the lower of the carrying amount or estimated fair value. Fair value of assets held for sale is equal to the estimated or contracted sales price with a potential buyer, less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value. We also analyze our investments in unconsolidated affiliates for impairment. This analysis consists of determining whether an expected loss in market value of an investment is other than temporary by evaluating the length of time and the extent to which the market value has been less than cost, the financial condition and near-term prospects of the investment, and our intent and ability to retain our investment for a period of time sufficient to allow for any anticipated recovery in market value. As the factors used in this analysis are difficult to predict and are subject to future events that may alter our assumptions, we may be required to recognize future impairment losses on our investments in unconsolidated affiliates. Sales of Real Estate For sales of real estate where we have collected the consideration to which we are entitled in exchange for transferring the real estate, the related assets and liabilities are removed from the balance sheet and the resultant gain or loss is recorded in the period the transaction closes. Any post sale involvement is accounted for as separate performance obligations and when the separate performance obligations are satisfied, the sales price allocated to each is recognized. Leases See Note 2 for significant accounting policies and related disclosures with respect to revenue recognition for our leases, accounting for initial direct costs and lease incentive costs and credit losses on operating lease receivables as a result of the lease standard adoption effective January 1, 2019. Discontinued Operations Properties that are sold or classified as held for sale are classified as discontinued operations provided that the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results. Interest expense is included in discontinued operations if a related loan securing the sold property is to be paid off or assumed by the buyer in connection with the sale. Investments in Unconsolidated Affiliates We account for our joint venture investments using the equity method of accounting when our interests represent a general partnership interest but substantive participating rights or substantive kick out rights have been granted to the limited partners or when our interests do not represent a general partnership interest and we do not control the major operating and financial policies of the investment. These investments are initially recorded at cost as investments in unconsolidated affiliates and are subsequently adjusted for our share of earnings and cash contributions and distributions. To the extent our cost basis at formation of the joint venture is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related assets and included in our share of equity in earnings of unconsolidated affiliates. Cash Equivalents We consider highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Restricted Cash Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as construction-related escrows, property disposition proceeds set aside and designated or intended to fund future tax-deferred exchanges of qualifying real estate investments and escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements. Redeemable Common Units and Preferred Units Limited partners holding Common Units other than the Company (“Redeemable Common Units”) have the right to put any and all of the Common Units to the Operating Partnership and the Company has the right to put any and all of the Preferred Units to the Operating Partnership in exchange for their liquidation preference plus accrued and unpaid distributions in the event of a corresponding redemption by the Company of the underlying Preferred Stock. Consequently, these Redeemable Common Units and Preferred Units are classified outside of permanent partners’ capital in the Operating Partnership's accompanying balance sheets. The recorded value of the Redeemable Common Units is based on fair value at the balance sheet date as measured by the closing price of Common Stock on that date multiplied by the total number of Redeemable Common Units outstanding. The recorded value of the Preferred Units is based on their redemption value. Income Taxes The Company has elected and expects to continue to qualify as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”). A corporate REIT is a legal entity that holds real estate assets and, through the payment of dividends to stockholders, is generally permitted to reduce or avoid the payment of federal and state income taxes at the corporate level. To maintain qualification as a REIT, the Company is required to pay dividends to its stockholders equal to at least 90.0% of its annual REIT taxable income, excluding net capital gains. The partnership agreement requires the Operating Partnership to pay economically equivalent distributions on outstanding Common Units at the same time that the Company pays dividends on its outstanding Common Stock. Other than income taxes related to its taxable REIT subsidiary, the Operating Partnership does not reflect any federal income taxes in its financial statements, since as a partnership the taxable effects of its operations are attributed to its partners. The Operating Partnership does record state income tax for states that tax partnership income directly. We conduct certain business activities through a taxable REIT subsidiary, as permitted under the Code. The taxable REIT subsidiary is subject to federal, state and local income taxes on its taxable income. We record provisions for income taxes based on its income recognized for financial statement purposes, including the effects of differences between such income and the amount recognized for tax purposes. Concentration of Credit Risk At December 31, 2019 , properties that we wholly own were leased to 1,785 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Atlanta, Nashville, Raleigh and Tampa. Our customers engage in a wide variety of businesses. No single customer generated more than 5% of our consolidated revenues during 2019 . We maintain our cash and cash equivalents and our restricted cash at financial or other intermediary institutions. The combined account balances at each institution may exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. Additionally, from time to time in connection with tax-deferred 1031 transactions, our restricted cash balances may be commingled with other funds being held by any such intermediary institution, which would subject our balance to the credit risk of the institution. Derivative 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 existing and prospective debt instruments. We generally do not hold or issue these derivative contracts for trading or speculative purposes. The interest rate on all of our variable rate debt is generally adjusted at one or three month intervals, subject to settlements under these interest rate hedge contracts. Interest rate swaps involve the receipt of variable rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income/(loss) and are subsequently reclassified into interest expense as interest payments are made on our debt. We account for terminated derivative instruments by recognizing the related accumulated other comprehensive income/(loss) balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated other comprehensive income/(loss) into earnings over the originally designated hedge period. Earnings Per Share and Per Unit Basic earnings per share of the Company is computed by dividing net income available for common stockholders by the weighted Common Shares outstanding - basic. Diluted earnings per share is computed by dividing net income available to common stockholders (inclusive of noncontrolling interests in the Operating Partnership) by the weighted Common Shares outstanding - basic plus the dilutive effect of options, warrants and convertible securities outstanding, including Common Units, using the treasury stock method. Weighted Common Shares outstanding - basic includes all unvested restricted stock where dividends received on such restricted stock are non-forfeitable. Basic earnings per unit of the Operating Partnership is computed by dividing net income available for common unitholders by the weighted Common Units outstanding - basic. Diluted earnings per unit is computed by dividing net income available to common unitholders by the weighted Common Units outstanding - basic plus the dilutive effect of options and warrants, using the treasury stock method. Weighted Common Units outstanding - basic includes all of the Company's unvested restricted stock where distributions received on such restricted stock are non-forfeitable. Recently Issued Accounting Standards The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item when the hedged item affects earnings. We adopted the ASU as of January 1, 2019 with no material effect on our Consolidated Financial Statements. The FASB issued an ASU that changes certain disclosure requirements for fair value measurements. The ASU is required to be adopted in 2020 and applied prospectively. We do not expect such adoption to have a material effect on our Notes to Consolidated Financial Statements.

Leases [Abstract]
Leases	Leases On January 1, 2019, we adopted Accounting Standards Codification Topic 842 “Leases” (“ASC 842”), which supersedes Accounting Standards Codification Topic 840 “Leases” (“ASC 840”). Information in this Note 2 with respect to our leases and lease related costs as both lessee and lessor and lease related receivables as lessor is presented under ASC 842 as of and for the year ended December 31, 2019 and under ASC 840 as of and for the year ended December 31, 2018 . We adopted ASC 842 using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2019 as a result of this adoption. ASC 842 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. We operate as both a lessor and a lessee. As a lessor, we are required under ASC 842 to account for leases using an approach that is substantially equivalent to ASC 840's guidance for operating leases and other leases such as sales-type leases and direct financing leases. In addition, ASC 842 requires lessors to capitalize and amortize only incremental direct leasing costs. As a lessee, we are required under the new standard to apply a dual approach, classifying leases, such as ground leases, as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. ASC 842 also requires lessees to record a right of use asset and a lease liability for all leases with a term of greater than a year regardless of their classification. We have also elected the practical expedient not to recognize right of use assets and lease liabilities for leases with a term of a year or less. On adoption of the standard, we elected the package of practical expedients provided for in ASC 842, including: • No reassessment of whether any expired or existing contracts were or contained leases; • No reassessment of the lease classification for any expired or existing leases; and • No reassessment of initial direct costs for any existing leases. The package of practical expedients was made as a single election and was consistently applied to all existing leases as of January 1, 2019. We also elected the practical expedient provided to lessors in a subsequent amendment to ASC 842 that removed the requirement to separate lease and nonlease components, provided certain conditions were met. Information as Lessor Under ASC 842 To generate positive cash flow, as a lessor, we generally lease our office properties to lessees in exchange for fixed monthly payments that cover rent, property taxes, insurance and certain cost recoveries, primarily common area maintenance (“CAM”). Office properties owned by us that are under lease are primarily located in Atlanta, Charlotte, Nashville, Orlando, Pittsburgh, Raleigh, Richmond and Tampa and are leased to a wide variety of lessees across many industries. Our leases were determined to be operating leases and mostly range from three to 10 years. Payments from customers for CAM are considered nonlease components that are separated from lease components and are generally accounted for in accordance with the revenue recognition standard. However, we qualified for and elected the practical expedient related to combining the components because the lease component is classified as an operating lease and the timing and pattern of transfer of CAM income, which is not the predominant component, is the same as the lease component. As such, consideration for CAM is accounted for as part of the overall consideration in the lease. Payments from customers for property taxes and insurance are considered noncomponents of the lease and therefore no consideration is allocated to them because they do not transfer a good or service to the customer. Fixed contractual payments from our leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Some of our leases are subject to annual changes in the Consumer Price Index (“CPI”). Although increases in the CPI are not estimated as part of our measurement of straight-line rental revenue, to the extent that actual CPI is greater or less than the CPI at lease commencement, the amount of straight-line rent recognized in a given year is affected accordingly. Some of our leases have termination options and/or extension options. Termination options allow the customer to terminate the lease prior to the end of the lease term under certain circumstances. Termination options generally become effective half way or further into the original lease term and require advance notification from the customer and payment of a termination fee that reimburses us for a portion of the remaining rent under the original lease term and the undepreciated lease inception costs such as commissions, tenant improvements and lease incentives. Termination fee income is recognized on a straight-line basis from the date of the executed termination agreement through lease expiration when the amount of the fee is determinable and collectability of the fee is reasonably assured. Our extension options generally require a re-negotiation with the customer at market rates. Initial direct costs, primarily commissions, related to the leasing of our office properties are included in deferred leasing costs and are stated at amortized cost. Such expenditures are part of the investment necessary to execute leases and, therefore, are classified as investment activities in the statement of cash flows. All leasing commissions paid to third parties and our in-house personnel for new leases or lease renewals are capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases. All other costs to negotiate or arrange a lease are expensed as incurred. Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign a lease, are capitalized in deferred leasing costs and amortized on a straight-line basis over the respective lease terms as a reduction of rental revenues. Lease related receivables, which include accounts receivable and accrued straight-line rents receivable, are reduced for credit losses. Such amounts are recognized as a reduction to rental and other revenues. We regularly evaluate the collectability of our lease related receivables. Our evaluation of collectability primarily consists of reviewing past due account balances and considering such factors as the credit quality of our customer, historical trends of the customer and changes in customer payment terms. Additionally, with respect to customers in bankruptcy, we estimate the probable recovery through bankruptcy claims and reduce the related receivable balance for amounts deemed uncollectible. If our assumptions regarding the collectability of lease related receivables prove incorrect, we could experience credit losses in excess of what was recognized in rental and other revenues. We recognized rental and other revenues related to operating lease payments of $723.1 million during the year ended December 31, 2019 , of which variable lease payments were $65.4 million . The following table sets forth the undiscounted cash flows for future minimum base rents to be received from customers for leases in effect at December 31, 2019 for the properties that we wholly own: 2020 $ 647,558 2021 621,080 2022 596,698 2023 537,225 2024 474,258 Thereafter 2,213,294 $ 5,090,113 Information as Lessor Under ASC 840 Minimum contractual rents from leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Contingent rental revenue, such as percentage rent, is accrued when the contingency is removed. Termination fee income is recognized at the later of when the customer has vacated the space or the lease has expired and a fully executed lease termination agreement has been delivered, the amount of the fee is determinable and collectability of the fee is reasonably assured. Cost recovery income is determined on a calendar year and a lease-by-lease basis. The most common types of cost recovery income in our leases are CAM and real estate taxes, for which a customer typically pays its pro-rata share of operating and administrative expenses and real estate taxes in excess of the costs incurred during a contractually specified base year. The computation of cost recovery income is complex and involves numerous judgments, including the interpretation of lease provisions. Leases are not uniform in dealing with such cost recovery income and there are many variations in the computation. Many customers make monthly fixed payments of CAM, real estate taxes and other cost reimbursement items. We accrue income related to these payments each month. We make quarterly accrual adjustments, positive or negative, to cost recovery income to adjust the recorded amounts to our best estimate of the final annual amounts to be billed and collected. After the end of the calendar year, we compute each customer's final cost recovery income and, after considering amounts paid by the customer during the year, issue a bill or credit for the appropriate amount to the customer. The differences between the amounts billed less previously received payments and the accrual adjustment are recorded as increases or decreases to cost recovery income when the final bills are prepared, which occurs during the first half of the subsequent year. Accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable are reduced by an allowance for amounts that may become uncollectible in the future. We regularly evaluate the adequacy of our allowance for doubtful accounts. The evaluation primarily consists of reviewing past due account balances and considering such factors as the credit quality of our customer, historical trends of the customer and changes in customer payment terms. Additionally, with respect to customers in bankruptcy, we estimate the probable recovery through bankruptcy claims and adjust the allowance for amounts deemed uncollectible. If our assumptions regarding the collectability of receivables prove incorrect, we could experience losses in excess of our allowance for doubtful accounts. The allowance and its related receivable are written-off when we have concluded there is a low probability of collection and we have discontinued collection efforts. The following table sets forth the activity of allowance for doubtful accounts: Balance at December 31, 2017 Additions Deductions Balance at December 31, 2018 Allowance for Doubtful Accounts - Straight-Line Rent $ 819 $ 599 $ (777 ) $ 641 Allowance for Doubtful Accounts - Accounts Receivable 753 969 (556 ) 1,166 Allowance for Doubtful Accounts - Notes Receivable 72 — (28 ) 44 Totals $ 1,644 $ 1,568 $ (1,361 ) $ 1,851 Balance at December 31, 2016 Additions Deductions Balance at December 31, 2017 Allowance for Doubtful Accounts - Straight-Line Rent $ 692 $ 1,503 $ (1,376 ) $ 819 Allowance for Doubtful Accounts - Accounts Receivable 624 500 (371 ) 753 Allowance for Doubtful Accounts - Notes Receivable 105 — (33 ) 72 Totals $ 1,421 $ 2,003 $ (1,780 ) $ 1,644 Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign a lease, are capitalized in deferred leasing costs and amortized on a straight-line basis over the respective lease terms as a reduction of rental revenues. Our real estate assets are leased to customers under operating leases. The minimum rental amounts under the leases are generally subject to scheduled fixed increases. Generally, the leases also provide that we receive cost recovery income from customers for increases in certain costs above the costs incurred during a contractually specified base year. The following table sets forth our scheduled future minimum base rents to be received from customers for leases in effect at December 31, 2018 for the properties that we wholly own: 2019 $ 618,014 2020 581,399 2021 524,381 2022 488,157 2023 428,461 Thereafter 2,068,891 $ 4,709,303 Information as Lessee Under ASC 842 We have 20 properties subject to operating ground leases in Atlanta, Nashville, Orlando, Raleigh and Tampa with a weighted average remaining term of 52 years. Rental payments on these leases are adjusted periodically based on either the CPI or on a pre-determined schedule. The monthly payments on a pre-determined schedule are recognized on a straight-line basis over the terms of the respective leases. Changes in the CPI are not estimated as part of our measurement of straight-line rental expense. Upon initial adoption of ASC 842, we recognized a lease liability of $35.3 million (in accounts payable, accrued expenses and other liabilities) and a related right of use asset of $29.7 million (in prepaid expenses and other assets) on our Consolidated Balance Sheets equal to the present value of the minimum lease payments required under each ground lease. The difference between the recorded lease liability and right of use asset represents the accrued straight-line rent liability previously recognized under ASC 840. We used a discount rate of approximately 4.5% , which was derived from our assessment of the credit quality of the Company and adjusted to reflect secured borrowing, estimated yield curves and long-term spread adjustments over appropriate tenors. Some of our ground leases contain extension options; however, these did not impact our calculation of the right of use asset and liability as they extend beyond the useful life of the properties subject to the operating ground leases. We recognized $2.5 million of ground lease expense, of which $2.2 million was paid in cash, during the year ended December 31, 2019 . The following table sets forth the undiscounted cash flows of our scheduled obligations for future minimum payments on operating ground leases at December 31, 2019 and a reconciliation of those cash flows to the operating lease liability at December 31, 2019 : 2020 $ 2,086 2021 2,127 2022 2,169 2023 2,167 2024 2,123 Thereafter 83,697 94,369 Discount (59,470 ) Lease liability $ 34,899 Information as Lessee Under ASC 840 Certain of our properties are subject to operating ground leases. Rental payments on these leases are adjusted periodically based on either the CPI or on a pre-determined schedule. Total rental property expense recorded for operating ground leases was $2.5 million for each the years ended December 31, 2018 and 2017 . The following table sets forth our scheduled obligations for future minimum payments on operating ground leases at December 31, 2018 : 2019 $ 2,184 2020 2,223 2021 2,263 2022 2,305 2023 2,308 Thereafter 86,577 $ 97,860

Real Estate [Abstract]
Real Estate Assets	Real Estate Assets Acquisitions During 2019, we acquired a building in the central business district of Charlotte, which delivered in 2019 and encompasses 841,000 rentable square feet, for a net purchase price of $399.1 million . The assets acquired and liabilities assumed were recorded at relative fair value as determined by management, with the assistance of third party specialists, based on information available at the acquisition date and on current assumptions as to future operations. During 2019, we also acquired four development parcels totaling approximately 10 acres in Raleigh, Richmond and Pittsburgh for an aggregate purchase price, including capitalized acquisition costs, of $12.4 million . During 2018, we acquired two development parcels totaling approximately nine acres in Nashville for an aggregate purchase price, including capitalized acquisition costs, of $50.6 million . During 2017, we acquired fee simple title to land in Raleigh that was previously subject to a ground lease for a purchase price, including capitalized acquisition costs and contingent consideration, of $2.6 million . Dispositions During 2019, we sold a total of six buildings and various land parcels for an aggregate sale price of $136.4 million and recorded aggregate gains on disposition of property of $39.5 million . During 2018, we sold a total of three buildings and various land parcels for an aggregate sale price of $90.6 million and recorded aggregate gains on disposition of property of $37.6 million . During 2017, we sold a total of 15 buildings and land for an aggregate sale price of $135.6 million (before closing credits to buyer of $3.7 million ) and recorded aggregate gains on disposition of property of $54.2 million . Impairments During 2019, we recorded aggregate impairments of real estate assets of $5.8 million as a result of shortened hold periods from classifying all of our assets in Greensboro and Memphis as non-core and changes in market-based inputs and our assumptions about the use of the assets. During 2018 and 2017, we recorded aggregate impairments of real estate assets of $0.4 million and $1.4 million , respectively. These impairments resulted from changes in market-based inputs and our assumptions about the use of the assets.

Equity Method Investments and Joint Ventures [Abstract]
Investments In and Advances To Affiliates	Investments in and Advances to Affiliates Unconsolidated Affiliates We have equity interests of up to 50.0% in various joint ventures with unrelated third parties that are accounted for using the equity method of accounting because we have the ability to exercise significant influence over the operating and financial policies of the joint venture investment. The difference between the cost of these investments and the net book value of the underlying net assets was $0.7 million and $0.6 million at December 31, 2019 and 2018 , respectively. The following table sets forth our ownership in unconsolidated affiliates at December 31, 2019 : Joint Venture Location Ownership Interest Plaza Colonnade, Tenant-in-Common Kansas City 50.0% Kessinger/Hunter & Company, LC Kansas City 26.5% Highwoods DLF Forum, LLC Raleigh 25.0% We receive development, management and leasing fees for services provided to certain of our joint ventures. These fees are recognized in income to the extent of our respective joint venture partner's interest. During the years ended December 31, 2019 , 2018 and 2017 , we recognized $ 0.5 million , $ 0.4 million and $ 1.4 million , respectively, of development/construction, management and leasing fees from our unconsolidated joint ventures. At both December 31, 2019 and 2018 , we had receivables of $0.1 million related to these fees in accounts receivable. Consolidated Variable Interest Entity During the second quarter of 2019, we and The Bromley Companies formed a joint venture (the "Midtown One joint venture”) to construct Midtown One, a 150,000 square foot, multi-customer office building located in the mixed-use Midtown Tampa project in Tampa’s Westshore submarket. Midtown One has an anticipated total investment of $71.3 million . Construction of Midtown One began in the third quarter of 2019 with a scheduled completion date in the second quarter of 2021. At closing, we agreed to contribute cash of $20.0 million ( $15.9 million of which was funded and/or placed in escrow as of December 31, 2019 ) in exchange for an 80.0% interest in the Midtown One joint venture and The Bromley Companies contributed land valued at $5.0 million in exchange for the remaining 20.0% interest. We also committed to provide a $46.3 million interest-only secured construction loan to the Midtown One joint venture that is scheduled to mature on the second anniversary of completion. The loan bears interest at LIBOR plus 250 basis points . As of December 31, 2019 , no amounts under the loan have been funded. We determined that we have a variable interest in the Midtown One joint venture primarily because the entity was designed to pass along interest rate risk, equity price risk and operation risk to us as both a debt and an equity holder and The Bromley Companies as an equity holder. The Midtown One joint venture was further determined to be a variable interest entity as it requires additional subordinated financial support in the form of a loan because the initial equity investment provided by us and The Bromley Companies is not sufficient to finance its planned investments and operations. We, as majority owner and managing member and through our control rights as set forth in the joint venture's governance documents, were determined to be the primary beneficiary as we have both the power to direct the activities that most significantly affect the entity (primarily lease rates, property operations and capital expenditures) and significant economic exposure through our equity investment and loan commitment. As such, the Midtown One joint venture was consolidated as of December 31, 2019 and for the period May 29, 2019 through December 31, 2019 and all intercompany transactions and accounts were eliminated. The following table sets forth the assets and liabilities of the Midtown One joint venture included on our Consolidated Balance Sheets: December 31, Development in-process $ 22,380 Accounts payable, accrued expenses and other liabilities $ 1,162 The assets of the Midtown One joint venture can be used only to settle obligations of the joint venture and its creditors have no recourse to our wholly owned assets. Other Consolidated Affiliate We have a 50.0% ownership interest in Highwoods-Markel Associates, LLC (“Markel”), a consolidated joint venture. We are the manager and leasing agent for Markel's properties, which are located in Richmond in exchange for customary management and leasing fees. We consolidate Markel since we are the managing member and control the major operating and financial policies of the entity. As controlling member, we have an obligation to cause this property-owning entity to distribute proceeds of liquidation to the noncontrolling interest member in these partially owned properties only if the net proceeds received by the entity from the sale of any of Markel's assets warrant a distribution as determined by the agreement governing the joint venture. We estimate the value of such noncontrolling interest distributions would have been $ 30.1 million had the entity been liquidated at December 31, 2019 . This estimated settlement value is based on the fair value of the underlying properties which is based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates and costs to operate each property. If the entity's underlying assets are worth less than the underlying liabilities on the date of such liquidation, we would have no obligation to remit any consideration to the noncontrolling interest holder.

(8) This debt was repaid in 2019 . (9) As more fully described in Note 7, we entered into floating-to-fixed interest rate swaps that effectively fix LIBOR for $50.0 million of this loan through January 2022. Accordingly, the equivalent fixed rate of this amount is 2.79% . The interest rate on the remaining $50.0 million was 2.81% at December 31, 2019 . (10) The interest rate was 2.90% at December 31, 2019 . (11) The interest rate was 2.73% at December 31, 2019 . The following table sets forth scheduled future principal payments, including amortization, due on our mortgages and notes payable at December 31, 2019 : Years Ending December 31, Principal Amount 2020 $ 248 2021 300,560 2022 521,842 2023 251,180 2024 1,281 Thereafter 1,481,617 Less-unamortized debt issuance costs (13,018 ) $ 2,543,710 During 2017, we entered into a $600.0 million unsecured revolving credit facility, which replaced our previously existing $475.0 million revolving credit facility, and includes an accordion feature that allows for an additional $400.0 million of borrowing capacity subject to additional lender commitments. Our revolving credit facility is scheduled to mature in January 2022. Assuming no defaults have occurred, we have an option to extend the maturity for two additional six-month periods. The interest rate at our current credit ratings is LIBOR plus 100 basis points and the annual facility fee is 20 basis points. The interest rate and facility fee are based on the higher of the publicly announced ratings from Moody's Investors Service or Standard & Poor’s Ratings Services. We incurred $3.5 million of debt issuance costs, which will be amortized along with certain existing unamortized debt issuance costs over the remaining term of our new revolving credit facility. We recorded $0.1 million of loss on debt extinguishment. There was $221.0 million and $225.0 million outstanding under our revolving credit facility at December 31, 2019 and January 24, 2020 , respectively. At both December 31, 2019 and January 24, 2020 , we had $ 0.1 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 December 31, 2019 and January 24, 2020 was $ 378.9 million and $ 374.9 million , respectively. During 2019, the Operating Partnership issued $400.0 million aggregate principal amount of 3.050% notes due February 2030, less original issuance discount of $1.0 million . These notes were priced to yield 3.079% . Underwriting fees and other expenses were incurred that aggregated $3.4 million ; these costs were deferred and will be amortized over the term of the notes. During 2019, the Operating Partnership issued $350.0 million aggregate principal amount of 4.20% notes due April 2029, less original issuance discount of $1.0 million . These notes were priced to yield 4.234% . Underwriting fees and other expenses were incurred that aggregated $3.1 million ; these costs were deferred and will be amortized over the term of the notes. During 2018, we paid off at maturity $200.0 million principal amount of 7.5% unsecured notes. During 2018, the Operating Partnership issued $350.0 million aggregate principal amount of 4.125% notes due March 2028, less original issuance discount of $4.1 million . These notes were priced to yield 4.271% . Underwriting fees and other expenses were incurred that aggregated $2.9 million ; these costs were deferred and will be amortized over the term of the notes. During 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% . We recorded $0.4 million of gain on debt extinguishment related to this prepayment. During 2017, we modified our $200.0 million , five-year unsecured bank term loan, which was originally scheduled to mature in January 2019. The modified term loan is scheduled to mature in November 2022 and the interest rate, based on current credit ratings, was reduced from LIBOR plus 120 basis points to LIBOR plus 110 basis points . We incurred $1.1 million of debt issuance costs, which will be amortized along with certain existing unamortized debt issuance costs over the remaining term of the modified loan. We recorded $0.4 million of loss on debt extinguishment. During 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 2017, the Operating Partnership issued $300.0 million aggregate principal amount of 3.875% notes due March 2027, less original issuance 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 2017, we paid off at maturity $379.7 million principal amount of 5.85% unsecured notes. We previously amended our $225.0 million , seven-year unsecured bank term loan, which was scheduled to mature in January 2019. We increased the borrowed amount to $350.0 million . The amended term loan was scheduled to mature in June 2020 and the interest rate, based on our current credit ratings, was reduced from LIBOR plus 175 basis points to LIBOR plus 110 basis points . We incurred $1.3 million of debt issuance costs in connection with this amendment, which was amortized along with existing unamortized debt issuance costs over the remaining term of the new loan. During 2017, we prepaid without penalty $125.0 million on this $350.0 million unsecured bank term loan and recorded $0.4 million of loss on debt extinguishment related to this prepayment. During 2019, we prepaid without penalty the remaining $225.0 million and recorded $0.4 million of loss on debt extinguishment related to this prepayment. We previously 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 was satisfied upon payment of a "waterfall payment." During 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. We previously borrowed an aggregate of $150.0 million under an unsecured bank term loan that is originally scheduled to mature in January 2022. The interest rate on the term loan at our current credit ratings is LIBOR plus 110 basis points . During 2017, we amended our $150.0 million unsecured bank term loan by increasing the borrowed amount to $200.0 million . 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. During 2019, we prepaid without penalty $100.0 million on this $200.0 million unsecured bank term loan. We recorded $0.3 million of loss on debt extinguishment related to this prepayment. Our revolving credit facility and bank term loans require us to comply with customary operating covenants and various financial requirements. Upon an event of default on the revolving credit facility, the lenders having at least 51.0% of the total commitments under the revolving credit facility can accelerate all borrowings then outstanding, and we could be prohibited from borrowing any further amounts under our revolving credit facility, which would adversely affect our ability to fund our operations. In addition, certain of our unsecured debt agreements contain cross-default provisions giving the unsecured lenders the right to declare a default if we are in default under more than $30.0 million with respect to other loans in some circumstances. We are currently in compliance with financial covenants with respect to our consolidated debt. The Operating Partnership has $299.4 million carrying amount of 2021 notes outstanding, $249.2 million carrying amount of 2023 notes outstanding, $297.1 million carrying amount of 2027 notes outstanding, $346.6 million carrying amount of 2028 notes outstanding, $349.1 million carrying amount of 2029 notes outstanding and $399.0 million carrying amount of 2030 notes outstanding. The indenture that governs these outstanding 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 have considered our short-term liquidity needs and the adequacy of our estimated cash flows from operating activities and other available financing sources to meet these needs. We intend to meet these short-term liquidity requirements through a combination of the following: • available cash and cash equivalents; • cash flows from operating activities; • issuance of debt securities by the Operating Partnership; • 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. Capitalized Interest Total interest capitalized to development and significant building and tenant improvement projects was $ 5.6 million , $ 6.7 million and $ 8.8 million for the years ended December 31, 2019 , 2018 and 2017 , respectively.

Upon the subsequent issuance of the $400.0 million aggregate principal amount of 3.050% notes due February 2030 during 2019, we terminated the forward-starting swaps and paid cash upon settlement. The unrealized loss of $6.6 million in accumulated other comprehensive income/(loss) will be reclassified to interest expense as interest payments are made on the debt. During 2018, we entered into an aggregate of $225.0 million notional amount of forward-starting swaps that effectively locked the underlying 10 -year treasury rate at a weighted average of 2.86% with respect to a planned issuance of debt securities by the Operating Partnership.

These swaps effectively fixed the underlying one -month LIBOR rate at a weighted average rate of 1.678% . During 2019, these interest rate swaps expired. The counterparties under our swaps are major financial institutions. The swap agreements contain a provision whereby if we default on certain of our indebtedness and which default results in repayment of such indebtedness being, or becoming capable of being, accelerated by the lender, then we could also be declared in default on our swaps. Our interest rate swaps have been designated as and are being accounted for as cash flow hedges with changes in fair value recorded in other comprehensive income/(loss) each reporting period. 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 debt.

The contingent consideration for each is payable in cash to a third party if and to the extent future development milestones as outlined in the purchase agreements are met. Environmental Matters Substantially all of our in-service and development properties have been subjected to Phase I environmental assessments and, in certain instances, Phase II environmental assessments. Such assessments and/or updates have not revealed, nor are we aware of, any environmental liability that we believe would have a material adverse effect on our Consolidated Financial Statements. Litigation, Claims and Assessments We are from time to time a party to a variety of legal proceedings, claims and assessments arising in the ordinary course of our business. We regularly assess the liabilities and contingencies in connection with these matters based on the latest information available. For those matters where it is probable that we have incurred or will incur a loss and the loss or range of loss can be reasonably estimated, the estimated loss is accrued and charged to income in our Consolidated Financial Statements. In other instances, because of the uncertainties related to both the probable outcome and amount or range of loss, a reasonable estimate of liability, if any, cannot be made. Based on the current expected outcome of such matters, none of these proceedings, claims or assessments is expected to have a material effect on our business, financial condition, results of operations or cash flows.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Noncontrolling Interests in Consolidated Affiliates At December 31, 2019 , our noncontrolling interests in consolidated affiliates relate to our joint venture partners' 50.0% interest in office properties in Richmond and 20.0% interest in an office development property in Tampa. Our joint venture partners are unrelated third parties. Noncontrolling Interests in the Operating Partnership Noncontrolling interests in the Operating Partnership relate to the ownership of Redeemable Common Units. Net income attributable to noncontrolling interests in the Operating Partnership is computed by applying the weighted average percentage of Redeemable Common Units during the period, as a percent of the total number of outstanding Common Units, to the Operating Partnership’s net income for the period after deducting distributions on Preferred Units. When a noncontrolling unitholder redeems a Common Unit for a share of Common Stock or cash, the noncontrolling interests in the Operating Partnership are reduced and the Company’s share in the Operating Partnership is increased by the fair value of each security at the time of redemption. The following table sets forth the Company's noncontrolling interests in the Operating Partnership: Year Ended December 31, 2019 2018 Beginning noncontrolling interests in the Operating Partnership $ 105,960 $ 144,009 Adjustment of noncontrolling interests in the Operating Partnership to fair value 29,557 (33,427 ) Conversions of Common Units to Common Stock (663 ) (4,043 ) Net income attributable to noncontrolling interests in the Operating Partnership 3,551 4,588 Distributions to noncontrolling interests in the Operating Partnership (5,189 ) (5,167 ) Total noncontrolling interests in the Operating Partnership $ 133,216 $ 105,960 The following table sets forth net income available for common stockholders and transfers from the Company's noncontrolling interests in the Operating Partnership: Year Ended December 31, 2019 2018 2017 Net income available for common stockholders $ 134,430 $ 169,343 $ 182,873 Increase in additional paid in capital from conversions of Common Units to Common Stock 663 4,043 511 Change from net income available for common stockholders and transfers from noncontrolling interests $ 135,093 $ 173,386 $ 183,384

Fair Value Disclosures [Abstract]
Disclosure About Fair Value of Financial Instruments	Disclosure About Fair Value of Financial Instruments The following summarizes the levels of inputs that we use to measure fair value. Level 1. Quoted prices in active markets for identical assets or liabilities. Our Level 1 asset is our investment in marketable securities that we use to pay benefits under our non-qualified deferred compensation plan. Our Level 1 liability is our non-qualified deferred compensation obligation. The Company's Level 1 noncontrolling interests in the Operating Partnership relate to the ownership of Common Units by various individuals and entities other than the Company. Level 2. Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Our Level 2 assets include the fair value of our mortgages and notes receivable and 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 assets include any real estate assets recorded at fair value on a non-recurring basis as a result of our quarterly impairment analysis, which are valued using unobservable local and national industry market data such as comparable sales, appraisals, brokers' opinions of value and/or the terms of definitive sales contracts. Significant increases or decreases in any valuation inputs in isolation would result in a significantly lower or higher fair value measurement. The following table sets forth our assets and liabilities and the Company's noncontrolling interests in the Operating Partnership that are measured or disclosed at fair value within the fair value hierarchy. Level 1 Level 2 Level 3 Total Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Observable Inputs Significant Unobservable Inputs Fair Value at December 31, 2019: Assets: Mortgages and notes receivable, at fair value (1) $ 1,501 $ — $ 1,501 $ — Marketable securities of non-qualified deferred compensation plan (in prepaid expenses and other assets) 2,345 2,345 — — Total Assets $ 3,846 $ 2,345 $ 1,501 $ — Noncontrolling Interests in the Operating Partnership $ 133,216 $ 133,216 $ — $ — Liabilities: Mortgages and notes payable, net, at fair value (1) $ 2,615,776 $ — $ 2,615,776 $ — Interest rate swaps (in accounts payable, accrued expenses and other liabilities) 154 — 154 — Non-qualified deferred compensation obligation (in accounts payable, accrued expenses and other liabilities) 2,345 2,345 — — Total Liabilities $ 2,618,275 $ 2,345 $ 2,615,930 $ — Fair Value at December 31, 2018: Assets: Mortgages and notes receivable, at fair value (1) $ 5,599 $ — $ 5,599 $ — Interest rate swaps (in prepaid expenses and other assets) 1,146 — 1,146 — Marketable securities of non-qualified deferred compensation plan (in prepaid expenses and other assets) 1,849 1,849 — — Impaired real estate assets 10,252 — — 10,252 Total Assets $ 18,846 $ 1,849 $ 6,745 $ 10,252 Noncontrolling Interests in the Operating Partnership $ 105,960 $ 105,960 $ — $ — Liabilities: Mortgages and notes payable, net, at fair value (1) $ 2,056,248 $ — $ 2,056,248 $ — Interest rate swaps (in accounts payable, accrued expenses and other liabilities) 3,581 — 3,581 — Non-qualified deferred compensation obligation (in accounts payable, accrued expenses and other liabilities) 1,849 1,849 — — Total Liabilities $ 2,061,678 $ 1,849 $ 2,059,829 $ — __________ (1) Amounts recorded at historical cost on our Consolidated Balance Sheets at December 31, 2019 and 2018 . The Level 3 impaired real estate assets measured at a fair value of $7.6 million in the third quarter of 2019 include an office building and land held for development. The aggregate impairments resulted from a change in our assumptions about the use of the assets and were calculated using brokers’ opinions of value and comparable sales as observable inputs were not available. The Level 3 impaired real estate assets measured at fair values of $0.7 million and $10.3 million in the second quarter of 2019 and fourth quarter of 2018, respectively, include land held for development. The impairments resulted from a change in our assumptions about the use of the assets and were calculated using the terms of definitive sales contracts as observable inputs were not available.

Equity	Equity Common Stock Issuances At December 31, 2019 , the Company had 96.2 million remaining shares of Common Stock authorized to be issued under its charter. Common Stock Dividends Dividends of the Company declared per share of Common Stock aggregated $1.90 , $1.85 and $1.76 for the years ended December 31, 2019 , 2018 and 2017 , respectively. The following table sets forth the Company's estimated taxability to the common stockholders of dividends per share for federal income tax purposes: Year Ended December 31, 2019 2018 2017 Ordinary dividend $ 1.64 $ 1.48 $ 1.50 Capital gains 0.13 0.31 0.32 Return of capital 0.13 0.06 — Total $ 1.90 $ 1.85 $ 1.82 The Company's tax returns have not been examined by the Internal Revenue Service (“IRS”) and, therefore, the taxability of dividends is subject to change.

Warrants At December 31, 2019 and 2018 , we had 15,000 warrants outstanding with an exercise price of $32.50 per share. Upon exercise of a warrant, the Company will contribute the exercise price to the Operating Partnership in exchange for Common Units. Therefore, the Operating Partnership accounts for such warrants as if issued by the Operating Partnership. These warrants have no expiration date. Common Unit Distributions Distributions of the Operating Partnership declared per Common Unit aggregated $1.90 , $1.85 and $1.76 for the years ended December 31, 2019 , 2018 and 2017 , respectively. Redeemable Common Units Generally, the Operating Partnership is obligated to redeem each Redeemable Common Unit at the request of the holder thereof for cash equal to the value of one share of Common Stock based on the average of the market price for the 10 trading days immediately preceding the notice date of such redemption, provided that the Company, at its option, may elect to acquire any such Redeemable Common Unit presented for redemption for cash or one share of Common Stock. When a holder redeems a Redeemable Common Unit for a share of Common Stock or cash, the Company’s share in the Operating Partnership will be increased. The Common Units owned by the Company are not redeemable.

Employee Benefit Plans

Employee Benefit Plans	12 Months Ended

Share-based Payment Arrangement [Abstract]
Employee Benefit Plans	Employee Benefit Plans Officer, Management and Director Compensation Programs Officers of the Company participate in an annual non-equity incentive program pursuant to which they are eligible to earn cash payments based on a percentage of their annual base salary in effect for December of the applicable year. Under this component of our executive compensation program, officers are eligible to earn additional cash compensation to the extent specific performance-based metrics are achieved during the most recently completed year. The position held by each officer has a target annual incentive percentage that ranges from 35% to 135% of base salary. The more senior the position, the greater the portion of compensation that varies with performance. The percentage amount an officer may earn under the annual non-equity incentive plan is the product of the target annual incentive percentage times an “actual performance factor,” which can range from zero to 200% . The actual performance factor depends upon the relationship between actual performance in specific areas at each of our divisions and predetermined goals. For corporate officers, the actual performance factor is based on the goals and criteria applied to the Company’s performance as a whole. For officers who oversee our divisions, the actual performance factor is based on the goals and criteria applied partly to that division’s performance and partly to the Company’s performance overall. Amounts under our annual non-equity incentive plan are accrued and expensed in the year earned, but are typically paid early in the following year. Certain other employees participate in a similar annual non-equity incentive program. Incentive eligibility ranges from 6% to 30% of annual base salary. The actual incentive payment is determined by a mix of the Company's overall performance, the performance of any applicable division and the individual’s performance during each year. These amounts are also accrued and expensed in the year earned, but are typically paid early in the following year. The Company's officers are eligible to receive a mix of long-term equity incentive awards on or about March 1 of each year. Prior to 2018, the mix generally consisted of stock options, time-based restricted stock and total return-based restricted stock. Since 2018, the mix has consisted of time-based restricted stock and total return-based restricted stock. Time-based restricted stock grants are also made annually to directors and certain other employees. Dividends received on restricted stock are non-forfeitable and are paid at the same rate and on the same date as on shares of Common Stock, except that, with respect to shares of total return-based restricted stock issued to the Company's chief executive officer, dividends accumulate and are payable only if and to the extent the shares vest. Dividends paid on subsequently forfeited shares are expensed. Additional shares of total return-based restricted stock may be issued at the end of the applicable measurement periods if and to the extent actual performance exceeds certain levels of performance. Such additional shares, if any, would be fully vested when issued. No expense is recorded for additional shares of total return-based restricted stock that may be issued at the end of the applicable measurement period since that possibility is reflected in the grant date fair value. The following table sets forth the number of shares of Common Stock reserved for future issuance under the Company's long-term equity incentive plans: December 31, 2019 2018 Outstanding stock options and warrants 599,902 611,518 Possible future issuance under equity incentive plans 2,016,659 2,188,696 2,616,561 2,800,214 Of the possible future issuance under the Company' long-term equity incentive plans at December 31, 2019 , no more than an additional 0.4 million shares can be in the form of restricted stock. During the years ended December 31, 2019 , 2018 and 2017 , we recognized $7.2 million , $7.5 million and $6.7 million , respectively, of share-based compensation expense. Because REITs generally do not pay income taxes, we do not realize tax benefits on share-based payments. At December 31, 2019 , there was $5.2 million of total unrecognized share-based compensation costs, which will be recognized over a weighted average remaining contractual term of 2.1 years. - Stock Options Stock options issued from 2014 through 2017 vest ratably on an annual basis over four years and expire after 10 years. Stock options issued in 2013 vest ratably on an annual basis over four years and expire after seven years . All stock options have an exercise price equal to the last reported stock price of our Common Stock on the New York Stock Exchange ("NYSE") on the last trading day prior to grant. The value of all options as of the date of grant is calculated using the Black-Scholes option-pricing model and is amortized over the respective vesting period or the service period, if shorter, for employees who are or will become eligible under the Company's retirement plan. The weighted average fair value of options granted during 2017 was $6.72 per option. The fair value of the options granted was determined at the grant date using the following assumptions: 2017 Risk free interest rate (1) 2.0 % Common stock dividend yield (2) 3.4 % Expected volatility (3) 19.5 % Average expected option life (years) (4) 5.75 __________ (1) Represents the interest rate as of the grant date on US treasury bonds having the same life as the estimated life of the option grants. (2) The dividend yield is calculated utilizing the then current regular dividend rate for a one-year period and the per share price of Common Stock on the date of grant. (3) Based on the historical volatility of Common Stock over a period relevant to the related stock option grant. (4) The average expected option life is based on an analysis of the Company's historical data. The following table sets forth stock option activity: Options Outstanding Number of Options Weighted Average Exercise Price Stock options outstanding at December 31, 2016 587,115 $ 42.26 Granted 168,748 52.49 Exercised (115,041 ) 40.41 Stock options outstanding at December 31, 2017 640,822 45.29 Exercised (44,304 ) 40.15 Stock options outstanding at December 31, 2018 596,518 45.67 Exercised (9,026 ) 39.53 Forfeited (2,590 ) 48.79 Stock options outstanding at December 31, 2019 (1) (2) 584,902 $ 45.75 __________ (1) The outstanding options at December 31, 2019 had a weighted average remaining life of 5.8 years. (2) The Company had 443,783 options exercisable at December 31, 2019 with a weighted average exercise price of $44.78 , weighted average remaining life of 5.6 years and intrinsic value of $2.1 million . Of these exercisable options, 84,374 had exercise prices higher than the market price of our Common Stock at December 31, 2019 . Cash received or receivable from options exercised was $0.4 million , $1.9 million and $5.2 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. The total intrinsic value of options exercised during the years ended December 31, 2019 , 2018 and 2017 was $0.1 million , $0.4 million and $1.3 million , respectively. The total intrinsic value of options outstanding at December 31, 2019 , 2018 and 2017 was $2.4 million , $0.1 million and $3.9 million , respectively. The Company generally does not permit the net cash settlement of exercised stock options, but does permit net share settlement so long as the shares received are held for at least a year. The Company has a practice of issuing new shares to satisfy stock option exercises. - Time-Based Restricted Stock Shares of time-based restricted stock vest ratably on an annual basis generally over four years . Beginning in 2019, shares of time-based restricted stock granted to non-employee directors vest on the first anniversary of the grant date. The value of grants of time-based restricted stock is based on the market value of Common Stock as of the date of grant and is amortized to expense over the respective vesting period or the service period, if shorter, for employees who are or will become eligible under the Company's retirement plan. The following table sets forth time-based restricted stock activity: Number of Shares Weighted Average Grant Date Fair Value Restricted shares outstanding at December 31, 2016 188,981 $ 42.06 Awarded and issued (1) 61,404 52.49 Vested (2) (78,139 ) 40.55 Restricted shares outstanding at December 31, 2017 172,246 46.46 Awarded and issued (1) 94,984 43.01 Vested (2) (73,307 ) 44.19 Forfeited (2,684 ) 45.89 Restricted shares outstanding at December 31, 2018 191,239 45.62 Awarded and issued (1) 103,590 45.98 Vested (2) (73,036 ) 45.79 Forfeited (3,642 ) 46.07 Restricted shares outstanding at December 31, 2019 218,151 $ 45.73 __________ (1) The weighted average fair value at grant date of time-based restricted stock issued during the years ended December 31, 2019 , 2018 and 2017 was $4.8 million , $4.1 million and $3.2 million , respectively. (2) The vesting date fair value of time-based restricted stock that vested during the years ended December 31, 2019 , 2018 and 2017 was $3.3 million , $3.2 million and $4.1 million , respectively. Vested shares include those shares surrendered by employees to satisfy tax withholding obligations in connection with such vesting. - Total Return-Based Restricted Stock Shares of total return-based restricted stock vest to the extent the Company's absolute total returns for certain pre-determined three-year periods exceed predetermined goals. The amount subject to vesting ranges from zero to 150% . Notwithstanding the Company’s absolute total return, if the Company’s total return exceeds 100% of the average peer group total return index, at least 75% of total return-based restricted stock issued will vest at the end of the applicable period. The weighted average grant date fair value of such shares of total return-based restricted stock issued in 2019 , 2018 and 2017 was determined to be $39.42 , $40.81 and $49.59 , respectively, and is amortized over the respective three-year period or the service period, if shorter, for employees who are or will become eligible under the Company's retirement plan. The fair values of the total return-based restricted stock granted were determined at the grant dates using a Monte Carlo simulation model and the following assumptions: 2019 2018 2017 Risk free interest rate (1) 2.4 % 2.3 % 1.6 % Common stock dividend yield (2) 4.4 % 3.9 % 3.5 % Expected volatility (3) 27.3 % 41.1 % 42.8 % __________ (1) Represents the interest rate as of the grant date on US treasury bonds having the same life as the estimated life of the total return-based restricted stock grants. (2) The dividend yield is calculated utilizing the then current regular dividend rate for a one-year period and the average per share price of Common Stock during the three-month period preceding the date of grant. (3) Based on the historical volatility of Common Stock over a period relevant to the related total return-based restricted stock grant. The following table sets forth total return-based restricted stock activity: Number of Shares Weighted Average Grant Date Fair Value Restricted shares outstanding at December 31, 2016 183,724 $ 39.82 Awarded and issued (1) (3) 84,013 44.76 Vested (2) (3) (107,013 ) 37.88 Restricted shares outstanding at December 31, 2017 160,724 44.72 Awarded and issued (1) 77,456 40.81 Vested (2) (41,160 ) 45.61 Forfeited (4) (16,926 ) 45.24 Restricted shares outstanding at December 31, 2018 180,094 43.34 Awarded and issued (1) 87,344 39.42 Vested (2) (45,901 ) 43.68 Forfeited (4) (12,689 ) 43.58 Restricted shares outstanding at December 31, 2019 208,848 $ 42.22 __________ (1) The fair value at grant date of total return-based restricted stock issued during the years ended December 31, 2019 , 2018 and 2017 was $3.4 million , $3.2 million and $2.4 million , respectively, at target. (2) The vesting date fair value of total return-based restricted stock that vested during the years ended December 31, 2019 , 2018 and 2017 was $2.1 million , $1.8 million and $5.6 million , respectively, based on the performance of the specific plans. Vested shares include those shares surrendered by employees to satisfy tax withholding obligations in connection with such vesting. (3) The 2017 amount includes 34,669 additional shares that were issued at the end of the applicable measurement period because actual performance exceeded certain levels of performance. (4) The 2019 and 2018 amounts include 9,521 and 13,707 shares, respectively, that were forfeited at the end of the applicable measurement period because the applicable total return did not meet the target level. 401(k) Retirement Savings Plan We have a 401(k) Retirement Savings Plan covering substantially all employees who meet certain age and employment criteria. We contribute amounts for each participant at a rate of 75% of the employee’s contribution (up to 6% of each employee’s bi-weekly salary and cash incentives, subject to statutory limits). During the years ended December 31, 2019 , 2018 and 2017 , we contributed $1.5 million , $1.4 million and $1.4 million , respectively, to the 401(k) savings plan. The assets of this qualified plan are not included in our Consolidated Financial Statements since the assets are not owned by us. Retirement Plan The Company has a retirement plan for employees with at least 30 years of continuous service or are at least 55 years old with at least 10 years of continuous service. Subject to advance written notice and a non-compete agreement, eligible retirees would be entitled to receive a pro rata amount of any annual non-equity incentive compensation earned during the year of retirement and stock options and time-based restricted stock would be non-forfeitable and vest according to the terms of their original grants. Eligible retirees would also be entitled to retain any total return-based restricted stock that subsequently vests after the retirement date according to the terms of their original grants. For employees who meet the age and service eligibility requirements, 100% of their annual grants are expensed at the grant date as if fully vested. For employees who will meet the age and service eligibility requirements within the normal vesting periods, the grants are amortized over the shorter service period. Deferred Compensation Prior to 2010, officers could elect to defer all or a portion of their cash compensation, which was then invested in unrelated mutual funds under a non-qualified deferred compensation plan. These investments are recorded at fair value, which aggregated $2.3 million and $1.8 million at December 31, 2019 and 2018 , respectively, and are included in prepaid expenses and other assets, with an offsetting deferred compensation liability recorded in accounts payable, accrued expenses and other liabilities. Deferred amounts ultimately payable to the participants are based on the value of the related mutual fund investments. Accordingly, changes in the value of the unrelated mutual funds are recorded in interest and other income and the corresponding offsetting changes in the deferred compensation liability are recorded in general and administrative expense. As a result, there is no effect on our net income. The following table sets forth our deferred compensation liability: Year Ended December 31, 2019 2018 2017 Beginning deferred compensation liability $ 1,849 $ 2,388 $ 2,451 Mark-to-market adjustment to deferred compensation (in general and administrative expenses) 496 (182 ) 492 Distributions from deferred compensation plans — (357 ) (555 ) Total deferred compensation liability $ 2,345 $ 1,849 $ 2,388 Employee Stock Purchase Plan The Company has an Employee Stock Purchase Plan ("ESPP") pursuant to which employees may contribute up to 25% of their cash compensation for the purchase of Common Stock. At the end of each quarter, each participant's account balance, which includes accumulated dividends, is applied to acquire shares of Common Stock at a cost that is calculated at 85% of the average closing price on the NYSE on the five consecutive days preceding the last day of the quarter. In the years ended December 31, 2019 , 2018 and 2017 , the Company issued 38,618 , 38,951 and 33,278 shares, respectively, of Common Stock under the ESPP. The 15% discount on newly issued shares, which is taxable income to the participants and is recorded by us as additional compensation expense, aggregated $0.3 million , $0.3 million and $0.2 million in the years ended December 31, 2019 , 2018 and 2017 , respectively. Generally, shares purchased under the ESPP must be held at least one year. The Company satisfies its ESPP obligations by issuing additional shares of Common Stock.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our Consolidated Financial Statements include the operations of the Company's taxable REIT subsidiary, which is not entitled to the dividends paid deduction and is subject to federal, state and local income taxes on its taxable income. The minimum dividend per share of Common Stock required for the Company to maintain its REIT status was $1.44 , $1.26 and $1.37 per share in 2019 , 2018 and 2017 , respectively. Continued qualification as a REIT depends on the Company's ability to satisfy the dividend distribution tests, stock ownership requirements and various other qualification tests. The tax basis of the Company's assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $4.7 billion and $2.9 billion , respectively, at December 31, 2019 and $4.3 billion and $2.3 billion , respectively, at December 31, 2018 . The tax basis of the Operating Partnership's assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $4.7 billion and $2.9 billion , respectively, at December 31, 2019 and $4.2 billion and $2.3 billion , respectively, at December 31, 2018 . During the years ended December 31, 2019 , 2018 and 2017 , the Company qualified as a REIT and incurred no federal income tax expense; accordingly, the only federal income taxes included in the accompanying Consolidated Financial Statements relate to activities of the Company's taxable REIT subsidiary. Due to the passage of federal legislation commonly known as the "Tax Cuts and Jobs Act," which was signed into law on December 22, 2017, the taxable REIT subsidiary was required to decrease the deferred tax asset balance, which resulted in an increase to tax expense of $0.1 million in 2017. The following table sets forth the Company's income tax expense/(benefit): Year Ended December 31, 2019 2018 2017 Current tax expense/(benefit): Federal $ 202 $ 133 $ (177 ) State 148 112 105 350 245 (72 ) Deferred tax expense/(benefit): Federal 14 (95 ) 223 State (120 ) (68 ) (9 ) (106 ) (163 ) 214 Total income tax expense $ 244 $ 82 $ 142 The Company's net deferred tax liability was $0.1 million and $0.2 million as of December 31, 2019 and 2018 , respectively. The net deferred tax liability is comprised primarily of tax versus book differences related to property (depreciation, amortization and basis differences). For the years ended December 31, 2019 and 2018 , there were no unrecognized tax benefits. The Company is subject to federal, state and local income tax examinations by taxing authorities for 2016 through 2019

Segment Reporting [Abstract]
Segment Information	Segment Information Our principal business is the operation, acquisition and development of rental real estate properties. We evaluate our business by geographic location. The operating results by geographic grouping are regularly reviewed by our chief operating decision maker for assessing performance and other purposes. There are no material inter-segment transactions. Our accounting policies of the segments are the same as those used in our Consolidated Financial Statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company's Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership's Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. We consolidate joint venture investments, such as interests in partnerships and limited liability companies, when we control the major operating and financial policies of the investment through majority ownership, in our capacity as a general partner or managing member or through some other contractual right. At December 31, 2019 , three properties owned through a joint venture investment were consolidated. We also consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. At December 31, 2019 , we have involvement with, and are the primary beneficiary in, an entity that we concluded to be a variable interest entity (see Note 4). In addition, during 2019, we acquired a building using a special purpose entity owned by a qualified intermediary to facilitate a potential Section 1031 reverse exchange under the Internal Revenue Code. To realize the tax deferral available under the Section 1031 exchange, we must complete the Section 1031 exchange, and take title to the to-be-exchanged building within 180 days of the acquisition date. We have determined that this entity is a variable interest entity of which we are the primary beneficiary and therefore, we consolidate this entity. As of December 31, 2019 , this variable interest entity had total assets, liabilities and cash flows of $425.0 million , $24.0 million and $2.5 million , respectively. All intercompany transactions and accounts have been eliminated. Certain amounts within the Consolidated Statements of Income for the years ended December 31, 2018 and 2017 were removed and/or combined to conform to the current year presentation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
Insurance	Insurance We are primarily self-insured for health care claims for participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities. At December 31, 2019 , a reserve of $0.6 million was recorded to cover estimated reported and unreported claims.
Real Estate and Related Assets	Real Estate and Related Assets Real estate and related assets are recorded at cost and stated at cost less accumulated depreciation. Renovations, replacements and other expenditures that improve or extend the life of assets are capitalized and depreciated over their estimated useful lives. Expenditures for ordinary maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful life of 40 years for buildings and depreciable land infrastructure costs, 15 years for building improvements and five to seven years for furniture, fixtures and equipment. Tenant improvements are amortized using the straight-line method over initial fixed terms of the respective leases, which generally are from three to 10 years. Depreciation expense for real estate assets was $ 214.7 million , $ 191.0 million and $ 184.4 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and are stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy and capitalize only those costs associated with the portion under construction. We record liabilities for the performance of asset retirement activities when the obligation to perform such activities is probable even when uncertainty exists about the timing and/or method of settlement. Upon the acquisition of real estate assets accounted for as asset acquisitions, we assess the fair value of acquired tangible assets such as land, buildings and tenant improvements, intangible assets and liabilities such as above and below market leases, acquired in-place leases and other identifiable intangible assets and assumed liabilities. We allocate fair value on a relative basis based on estimated cash flow projections that utilize discount and/or capitalization rates as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. The above and below market rate portions of leases acquired in connection with property acquisitions are recorded in deferred leasing costs and in accounts payable, accrued expenses and other liabilities, respectively, at fair value and amortized into rental revenue over the remaining term of the respective leases as described below. Fair value is calculated as the present value of the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) our estimate of fair market lease rates for each corresponding in-place lease, using a discount rate that reflects the risks associated with the leases acquired and measured over a period equal to the remaining initial term of the lease for above-market leases and the remaining initial term plus the term of any renewal option that the customer would be economically compelled to exercise for below-market leases. In-place leases acquired are recorded at fair value in deferred leasing costs and are amortized to depreciation and amortization expense over the remaining term of the respective lease. The value of in-place leases is based on our evaluation of the specific characteristics of each customer's lease. Factors considered include estimates of carrying costs during hypothetical expected lease-up periods, current market conditions, the customer's credit quality and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider tenant improvements, leasing commissions and legal and other related expenses. Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the sale of the asset is probable, has been duly approved by the Company, a legally enforceable contract has been executed and the buyer's due diligence period, if any, has expired.
Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates	Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates With respect to assets classified as held for use, we perform an impairment analysis if our evaluation of events or changes in circumstances indicate that the carrying value may not be recoverable, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset's carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete. If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and are subject to future events that may alter our assumptions, the discounted and/or undiscounted future operating and residual cash flows estimated by us in our impairment analyses or those established by appraisal may not be achieved and we may be required to recognize future impairment losses on properties held for use. We record assets held for sale at the lower of the carrying amount or estimated fair value. Fair value of assets held for sale is equal to the estimated or contracted sales price with a potential buyer, less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value. We also analyze our investments in unconsolidated affiliates for impairment. This analysis consists of determining whether an expected loss in market value of an investment is other than temporary by evaluating the length of time and the extent to which the market value has been less than cost, the financial condition and near-term prospects of the investment, and our intent and ability to retain our investment for a period of time sufficient to allow for any anticipated recovery in market value. As the factors used in this analysis are difficult to predict and are subject to future events that may alter our assumptions, we may be required to recognize future impairment losses on our investments in unconsolidated affiliates.
Sales of Real Estate	Sales of Real Estate For sales of real estate where we have collected the consideration to which we are entitled in exchange for transferring the real estate, the related assets and liabilities are removed from the balance sheet and the resultant gain or loss is recorded in the period the transaction closes. Any post sale involvement is accounted for as separate performance obligations and when the separate performance obligations are satisfied, the sales price allocated to each is recognized.
Discontinued Operations	Discontinued Operations Properties that are sold or classified as held for sale are classified as discontinued operations provided that the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results. Interest expense is included in discontinued operations if a related loan securing the sold property is to be paid off or assumed by the buyer in connection with the sale.
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates We account for our joint venture investments using the equity method of accounting when our interests represent a general partnership interest but substantive participating rights or substantive kick out rights have been granted to the limited partners or when our interests do not represent a general partnership interest and we do not control the major operating and financial policies of the investment. These investments are initially recorded at cost as investments in unconsolidated affiliates and are subsequently adjusted for our share of earnings and cash contributions and distributions. To the extent our cost basis at formation of the joint venture is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related assets and included in our share of equity in earnings of unconsolidated affiliates.
Cash Equivalents	Cash Equivalents We consider highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
Restricted Cash	Restricted Cash Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as construction-related escrows, property disposition proceeds set aside and designated or intended to fund future tax-deferred exchanges of qualifying real estate investments and escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements.
Redeemable Common Units and Preferred Units	Redeemable Common Units and Preferred Units Limited partners holding Common Units other than the Company (“Redeemable Common Units”) have the right to put any and all of the Common Units to the Operating Partnership and the Company has the right to put any and all of the Preferred Units to the Operating Partnership in exchange for their liquidation preference plus accrued and unpaid distributions in the event of a corresponding redemption by the Company of the underlying Preferred Stock. Consequently, these Redeemable Common Units and Preferred Units are classified outside of permanent partners’ capital in the Operating Partnership's accompanying balance sheets. The recorded value of the Redeemable Common Units is based on fair value at the balance sheet date as measured by the closing price of Common Stock on that date multiplied by the total number of Redeemable Common Units outstanding. The recorded value of the Preferred Units is based on their redemption value.
Income Tax	Income Taxes The Company has elected and expects to continue to qualify as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”). A corporate REIT is a legal entity that holds real estate assets and, through the payment of dividends to stockholders, is generally permitted to reduce or avoid the payment of federal and state income taxes at the corporate level. To maintain qualification as a REIT, the Company is required to pay dividends to its stockholders equal to at least 90.0% of its annual REIT taxable income, excluding net capital gains. The partnership agreement requires the Operating Partnership to pay economically equivalent distributions on outstanding Common Units at the same time that the Company pays dividends on its outstanding Common Stock. Other than income taxes related to its taxable REIT subsidiary, the Operating Partnership does not reflect any federal income taxes in its financial statements, since as a partnership the taxable effects of its operations are attributed to its partners. The Operating Partnership does record state income tax for states that tax partnership income directly. We conduct certain business activities through a taxable REIT subsidiary, as permitted under the Code. The taxable REIT subsidiary is subject to federal, state and local income taxes on its taxable income. We record provisions for income taxes based on its income recognized for financial statement purposes, including the effects of differences between such income and the amount recognized for tax purposes.
Concentration of Credit Risk	Concentration of Credit Risk At December 31, 2019 , properties that we wholly own were leased to 1,785 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Atlanta, Nashville, Raleigh and Tampa. Our customers engage in a wide variety of businesses. No single customer generated more than 5% of our consolidated revenues during 2019 . We maintain our cash and cash equivalents and our restricted cash at financial or other intermediary institutions. The combined account balances at each institution may exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. Additionally, from time to time in connection with tax-deferred 1031 transactions, our restricted cash balances may be commingled with other funds being held by any such intermediary institution, which would subject our balance to the credit risk of the institution.
Derivative Financial Instruments	Derivative 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 existing and prospective debt instruments. We generally do not hold or issue these derivative contracts for trading or speculative purposes. The interest rate on all of our variable rate debt is generally adjusted at one or three month intervals, subject to settlements under these interest rate hedge contracts. Interest rate swaps involve the receipt of variable rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income/(loss) and are subsequently reclassified into interest expense as interest payments are made on our debt. We account for terminated derivative instruments by recognizing the related accumulated other comprehensive income/(loss) balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated other comprehensive income/(loss) into earnings over the originally designated hedge period.
Earnings Per Share and Per Unit	Earnings Per Share and Per Unit Basic earnings per share of the Company is computed by dividing net income available for common stockholders by the weighted Common Shares outstanding - basic. Diluted earnings per share is computed by dividing net income available to common stockholders (inclusive of noncontrolling interests in the Operating Partnership) by the weighted Common Shares outstanding - basic plus the dilutive effect of options, warrants and convertible securities outstanding, including Common Units, using the treasury stock method. Weighted Common Shares outstanding - basic includes all unvested restricted stock where dividends received on such restricted stock are non-forfeitable. Basic earnings per unit of the Operating Partnership is computed by dividing net income available for common unitholders by the weighted Common Units outstanding - basic. Diluted earnings per unit is computed by dividing net income available to common unitholders by the weighted Common Units outstanding - basic plus the dilutive effect of options and warrants, using the treasury stock method. Weighted Common Units outstanding - basic includes all of the Company's unvested restricted stock where distributions received on such restricted stock are non-forfeitable.
Recently Issued Accounting Standards	Recently Issued Accounting Standards The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item when the hedged item affects earnings. We adopted the ASU as of January 1, 2019 with no material effect on our Consolidated Financial Statements. The FASB issued an ASU that changes certain disclosure requirements for fair value measurements. The ASU is required to be adopted in 2020 and applied prospectively. We do not expect such adoption to have a material effect on our Notes to Consolidated Financial Statements. On January 1, 2019, we adopted Accounting Standards Codification Topic 842 “Leases” (“ASC 842”), which supersedes Accounting Standards Codification Topic 840 “Leases” (“ASC 840”). Information in this Note 2 with respect to our leases and lease related costs as both lessee and lessor and lease related receivables as lessor is presented under ASC 842 as of and for the year ended December 31, 2019 and under ASC 840 as of and for the year ended December 31, 2018 . We adopted ASC 842 using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2019 as a result of this adoption. ASC 842 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. We operate as both a lessor and a lessee. As a lessor, we are required under ASC 842 to account for leases using an approach that is substantially equivalent to ASC 840's guidance for operating leases and other leases such as sales-type leases and direct financing leases. In addition, ASC 842 requires lessors to capitalize and amortize only incremental direct leasing costs. As a lessee, we are required under the new standard to apply a dual approach, classifying leases, such as ground leases, as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. ASC 842 also requires lessees to record a right of use asset and a lease liability for all leases with a term of greater than a year regardless of their classification. We have also elected the practical expedient not to recognize right of use assets and lease liabilities for leases with a term of a year or less. On adoption of the standard, we elected the package of practical expedients provided for in ASC 842, including: • No reassessment of whether any expired or existing contracts were or contained leases; • No reassessment of the lease classification for any expired or existing leases; and • No reassessment of initial direct costs for any existing leases. The package of practical expedients was made as a single election and was consistently applied to all existing leases as of January 1, 2019. We also elected the practical expedient provided to lessors in a subsequent amendment to ASC 842 that removed the requirement to separate lease and nonlease components, provided certain conditions were met.

Recently Issued Accounting Standards	Recently Issued Accounting Standards The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item when the hedged item affects earnings. We adopted the ASU as of January 1, 2019 with no material effect on our Consolidated Financial Statements. The FASB issued an ASU that changes certain disclosure requirements for fair value measurements. The ASU is required to be adopted in 2020 and applied prospectively. We do not expect such adoption to have a material effect on our Notes to Consolidated Financial Statements. On January 1, 2019, we adopted Accounting Standards Codification Topic 842 “Leases” (“ASC 842”), which supersedes Accounting Standards Codification Topic 840 “Leases” (“ASC 840”). Information in this Note 2 with respect to our leases and lease related costs as both lessee and lessor and lease related receivables as lessor is presented under ASC 842 as of and for the year ended December 31, 2019 and under ASC 840 as of and for the year ended December 31, 2018 . We adopted ASC 842 using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2019 as a result of this adoption. ASC 842 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. We operate as both a lessor and a lessee. As a lessor, we are required under ASC 842 to account for leases using an approach that is substantially equivalent to ASC 840's guidance for operating leases and other leases such as sales-type leases and direct financing leases. In addition, ASC 842 requires lessors to capitalize and amortize only incremental direct leasing costs. As a lessee, we are required under the new standard to apply a dual approach, classifying leases, such as ground leases, as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. ASC 842 also requires lessees to record a right of use asset and a lease liability for all leases with a term of greater than a year regardless of their classification. We have also elected the practical expedient not to recognize right of use assets and lease liabilities for leases with a term of a year or less. On adoption of the standard, we elected the package of practical expedients provided for in ASC 842, including: • No reassessment of whether any expired or existing contracts were or contained leases; • No reassessment of the lease classification for any expired or existing leases; and • No reassessment of initial direct costs for any existing leases. The package of practical expedients was made as a single election and was consistently applied to all existing leases as of January 1, 2019. We also elected the practical expedient provided to lessors in a subsequent amendment to ASC 842 that removed the requirement to separate lease and nonlease components, provided certain conditions were met.
