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, 2018 , we owned or had an interest in 30.5 million rentable square feet of in-service properties, 1.8 million rentable square feet of properties under development and approximately 350 acres of development land. The Company is the sole general partner of the Operating Partnership. At December 31, 2018 , the Company owned all of the Preferred Units and 103.1 million , or 97.4% , of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.7 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 2018 , the Company redeemed 90,001 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, 2018 , three properties owned through a joint venture investment were consolidated. All intercompany transactions and accounts have been eliminated. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates. Insurance Beginning in 2018, we are primarily self-insured for health care claims for 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, 2018 , a reserve of $0.5 million was recorded to cover estimated reported and unreported claims. 1. Description of Business and Significant Accounting Policies – Continued 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 $ 191.0 million , $ 184.4 million and $ 173.1 million for the years ended December 31, 2018 , 2017 and 2016 , 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. Expenditures directly related to the leasing of 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 for new leases or lease renewals are capitalized. Internal leasing costs, which consist primarily of compensation, benefits and other costs, such as legal fees related to leasing activities, that are incurred in connection with successfully obtaining leases of properties are also capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases, which generally are from three to 10 years. Estimated costs related to unsuccessful activities are expensed as incurred. 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, 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, customer relationships and other identifiable intangible assets and assumed liabilities. We assess fair value 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. 1. Description of Business and Significant Accounting Policies – Continued 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 events or changes in circumstances indicate that the carrying value may be impaired, 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. 1. Description of Business and Significant Accounting Policies – Continued Rental and Other Revenues 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 common area maintenance (“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. Allowance for Doubtful Accounts 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. 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. Lease Incentives 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. 1. Description of Business and Significant Accounting Policies – Continued 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. 1. Description of Business and Significant Accounting Policies – Continued Concentration of Credit Risk At December 31, 2018 , properties that we wholly own were leased to 1,654 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Raleigh, Atlanta, Tampa and Nashville. Our customers engage in a wide variety of businesses. No single customer generated more than 5% of our consolidated revenues during 2018 . 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 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. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income/(loss) and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings. We account for terminated derivative instruments by recognizing the related accumulated 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 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. 1. Description of Business and Significant Accounting Policies – Continued Recently Issued Accounting Standards The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("ASU") that superseded the revenue recognition requirements under previous guidance, which we adopted as of January 1, 2018. Several updates have been issued subsequently that are intended to promote a more consistent interpretation and application of the principles outlined in the ASU. The ASU requires the use of a new five-step model to recognize revenue from contracts with customers. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We are also required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In analyzing our contracts with customers, we determined that the most material potential impact from the adoption of this ASU would be in how revenue is recognized for sales of real estate with post sale involvement. Prior to the adoption of this ASU, profit for such sales transactions was recognized and then reduced by the maximum exposure to loss related to the nature of the post sale involvement at the time of sale. Upon adoption of this ASU, any post sale involvement must be accounted for as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the post sale involvement performance obligation is satisfied, the portion of the sales price allocated to it will be recognized. We had no sales of real estate with continuing involvement during the year ended December 31, 2018 or prior periods; however, we will use such methodology for any future real estate sales with continuing involvement. Our internal controls with respect to accounting for such sales have been updated accordingly. Adoption of this ASU resulted in no other changes with respect to the timing of revenue recognition or internal controls related to contracts such as management, development and construction fees and transient parking income, all of which are not material to our Consolidated Financial Statements. As such, there is no cumulative-effect adjustment from the adoption of this ASU reflected in our Consolidated Financial Statements. The FASB issued an ASU that requires entities to show changes in total cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of period balances rather than presented as transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. We adopted the ASU as of January 1, 2018 with retrospective application to our Consolidated Statements of Cash Flows. Accordingly, our Consolidated Statements of Cash Flows present a reconciliation of the changes in cash and cash equivalents and restricted cash. The effect of the adoption resulted in a $55.9 million decrease in net cash used in investing activities for the year ended December 31, 2017 and a $12.4 million increase in net cash provided by investing activities for the year ended December 31, 2016 . The FASB issued an ASU that clarifies and narrows the definition of a business used in determining whether to account for a transaction as an asset acquisition or business combination. The guidance requires evaluation of the fair value of the assets acquired to determine if it is concentrated in a single identifiable asset or a group of similar identifiable assets. If so, the transferred assets would not be a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs. We adopted the ASU prospectively as of January 1, 2018. We expect that the majority of our future acquisitions would not meet the definition of a business; therefore, the related acquisition costs would be capitalized as part of the purchase price. The FASB issued an ASU that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance requires modification accounting if the value, vesting conditions or classification of the award changes. We adopted the ASU as of January 1, 2018 with no effect on our Consolidated Financial Statements. 1. Description of Business and Significant Accounting Policies – Continued The FASB issued an ASU that sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. In addition, the guidance requires lessors to capitalize and amortize only incremental direct leasing costs. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right of use asset and a lease liability for all leases with a term of greater than a year regardless of their classification. Leases with a term of a year or less will be accounted for in the same manner as operating leases today. The guidance supersedes previously issued guidance under ASC Topic 840 “Leases.” An entity may elect a package of practical expedients, which allows for the following: • An entity need not reassess whether any expired or existing contracts are or contain leases; • An entity need not reassess the lease classification for any expired or existing leases; and • An entity need not reassess initial direct costs for any existing leases. This package of practical expedients is available as a single election that must be consistently applied to all existing leases at the date of adoption. Furthermore, the FASB finalized an amendment that allows entities to present comparative periods, in the year of adoption, under ASC 840, which effectively allows for an initial date of adoption of January 1, 2019. The amendment also provides a practical expedient to lessors that removes the requirement to separate lease and non-lease components, provided certain conditions are met. Our analysis of our leases indicates that the lease component is the predominant component, that the timing and pattern of transfer of our material non-lease components (primarily cost reco

Real Estate [Abstract]
Real Estate Assets	Real Estate Assets Acquisitions 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. During 2016, we acquired a building in Raleigh, which encompasses 243,000 rentable square feet, for a net purchase price of $76.9 million. We expensed $0.3 million of acquisition costs (included in general and administrative expenses) related to this acquisition. The assets acquired and liabilities assumed were recorded at 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 2016, we also acquired: • fee simple title to the land underneath one of our buildings in Pittsburgh that was previously subject to a ground lease for a purchase price of $18.5 million. We expensed $0.5 million of acquisition costs (included in general and administrative expenses) related to this acquisition; • an acre of development land in Raleigh for a purchase price, including capitalized acquisition costs, of $5.8 million; and • 14 acres of development land in Nashville for a purchase price, including capitalized acquisition costs, of $9.1 million. Dispositions 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. During 2016, we sold: • substantially all of our wholly-owned Country Club Plaza assets in Kansas City (which we refer to as the “Plaza assets”) for a sale price of $660.0 million (before closing credits to buyer of $4.8 million). We recorded gains on disposition of discontinued operations of $414.5 million and a gain on disposition of property of $1.3 million related to the land; and 2. Real Estate Assets - Continued • a 32,000 square foot building for a sale price of $4.7 million (before closing credits to buyer of $0.1 million) and recorded a gain on disposition of property of $1.1 million. The buyer, which leased 79% of the building, is a family business controlled by a director of the Company. The sale price exceeded the value set forth in an appraisal performed by a reputable independent commercial real estate services firm that has no relationship with the director or any of his affiliates. During 2016, we also sold two buildings and various land parcels for an aggregate sale price of $31.1 million (before closing credits to buyer of $0.5 million) and recorded aggregate gains on disposition of property of $12.4 million. We deferred $0.4 million of gain related to a land sale for a portion of the sale price that was escrowed for contingent future infrastructure work. Impairments We recorded aggregate impairments of real estate assets of $0.4 million and $1.4 million in 2018 and 2017, 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 $0.6 million and $0.7 million at December 31, 2018 and 2017 , respectively. The following table sets forth our ownership in unconsolidated affiliates at December 31, 2018 : 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% Highwoods DLF 98/29, LLC Orlando 22.8% 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, 2018 , 2017 and 2016 , we recognized $ 0.4 million , $ 1.4 million and $ 0.8 million , respectively, of development/construction, management and leasing fees from our unconsolidated joint ventures. At both December 31, 2018 and 2017 , we had receivables of $0.1 million related to these fees in accounts receivable. Consolidated Affiliates 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, 2018 . 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.

Our new 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 on the new facility 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. The financial and other covenants under the new facility are similar to our previous credit facility. 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 $182.0 million and $191.0 million outstanding under our new revolving credit facility at December 31, 2018 and January 25, 2019 , respectively. At both December 31, 2018 and January 25, 2019 , we had $ 0.2 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, 2018 and January 25, 2019 was $ 417.8 million and $ 408.8 million , respectively. During 2018, we paid off at maturity $200.0 million principal amount of 7.5% unsecured notes. We also paid down $1.8 million of secured loan balances through principal amortization during 2018 . During 2018, the Operating Partnership issued $350.0 million aggregate principal amount of 4.125% notes due 2028, less original issuance discount of $4.1 million. These notes were priced to yield 4.271%. Underwriting fees and other expenses were incurred that aggregated $2.9 million; these costs were deferred and will be amortized over the term of the notes. 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 now 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. 5. Mortgages and Notes Payable - Continued During 2017, the Operating Partnership issued $300.0 million aggregate principal amount of 3.875% notes due 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 is 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 will be 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. We 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. During 2016, we prepaid without penalty the remaining $43.6 million balance on a secured mortgage loan with an effective interest rate of 7.5% that was originally scheduled to mature in August 2016. During 2016, we 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. We previously obtained a $350.0 million, six-month unsecured bridge facility. The interest rate on the bridge facility at our current credit ratings was LIBOR plus 110 basis points. During 2016, we prepaid without penalty the full balance on this unsecured bridge facility. 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. 5. Mortgages and Notes Payable - Continued The Operating Partnership has $298.9 million carrying amount of 2021 notes outstanding, $248.9 million carrying amount of 2023 notes outstanding, $296.7 million carrying amount of 2027 notes outstanding and $346.2 million carrying amount of 2028 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 (some of which debt securities may be hedged to a fixed interest rate pursuant to the forward-starting swaps referred to in Note 6); • issuance of secured debt; • bank term loans; • borrowings under our revolving credit facility; • issuance of equity securities by the Company or the Operating Partnership; and • the disposition of non-core assets. Capitalized Interest Total interest capitalized to development and significant building and tenant improvement projects was $ 6.7 million , $ 8.8 million and $ 8.2 million for the years ended December 31, 2018 , 2017 and 2016 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments During 2018, we entered into an aggregate of $225.0 million notional amount of forward-starting swaps that effectively lock 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 expected to occur prior to June 11, 2019. During 2017, we entered into $150.0 million notional amount of forward-starting swaps that effectively locked the underlying 10 -year treasury rate at 2.44% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $350.0 million aggregate principal amount of 4.125% notes due 2028 during 2018, we terminated the forward-starting swaps and received cash upon settlement. The unrealized gain of $7.0 million in accumulated other comprehensive income will be reclassified to interest expense as interest payments are made on the debt and a gain of $0.2 million of hedge ineffectiveness was recognized in interest expense. During 2017, we also entered into floating-to-fixed interest rate swaps through January 2022 with respect to an aggregate of $50.0 million LIBOR-based borrowings. These swaps effectively fix the underlying one -month LIBOR rate at a weighted average rate of 1.693% . During 2016, we entered into $150.0 million notional amount of forward-starting swaps that effectively locked the underlying 10 -year treasury rate at 1.90% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $300.0 million aggregate principal amount of 3.875% notes due 2027 during 2017, we terminated the forward-starting swaps and received cash upon settlement. The unrealized gain of $7.3 million in accumulated other comprehensive income will be reclassified to interest expense as interest payments are made on the debt. 6. Derivative Financial Instruments - Continued We also had floating-to-fixed interest rate swaps through January 11, 2019 with respect to an aggregate of $225.0 million LIBOR-based borrowings. These swaps effectively fixed the underlying one-month LIBOR rate at a weighted average rate of 1.678% . The counterparties under our swaps are major financial institutions. The swap agreements contain a provision whereby if we default on certain of our indebtedness and which default results in repayment of such indebtedness being, or becoming capable of being, accelerated by the lender, then we could also be declared in default on our swaps. Our interest rate swaps have been designated as and are being accounted for as cash flow hedges with the effective portion of changes in fair value recorded in other comprehensive income each reporting period. No significant gain or loss was recognized related to hedge ineffectiveness or to amounts excluded from effectiveness testing on our cash flow hedges during the years ended December 31, 2018 and 2017 . We have no collateral requirements related to our interest rate swaps. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our debt. During 2019 , we estimate that $1.6 million will be reclassified as a net decrease to interest expense. The following table sets forth the gross fair value of our derivatives: December 31, 2018 2017 Derivatives: Derivatives designated as cash flow hedges in prepaid expenses and other assets: Interest rate swaps $ 1,146 $ 1,286 Derivatives designated as cash flow hedges in accounts payable, accrued expenses and other liabilities: Interest rate swaps $ 3,581 $ — The following table sets forth the effect of our cash flow hedges on accumulated other comprehensive income and interest expense: Year Ended December 31, 2018 2017 2016 Derivatives Designated as Cash Flow Hedges: Amount of unrealized gains recognized in accumulated other comprehensive income on derivatives (effective portion): Interest rate swaps $ 4,161 $ 1,732 $ 5,703 Amount of (gains)/losses reclassified out of accumulated other comprehensive income into contractual interest expense (effective portion): Interest rate swaps $ (2,086 ) $ 1,157 $ 3,057

Lease and contractual commitments represent commitments under signed leases and contracts for operating properties (excluding tenant-funded tenant improvements) and contracts for development/redevelopment projects, of which $60.4 million was recorded on our Consolidated Balance Sheets at December 31, 2018 . Contingent Consideration We had $5.0 million at both December 31, 2018 and 2017 of contingent consideration related to certain parcels of acquired development land in Raleigh, Atlanta and Nashville. 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, 2018 , our noncontrolling interests in consolidated affiliates relate to our joint venture partner's 50.0% interest in office properties in Richmond. Our joint venture partner is an unrelated third party. 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, 2018 2017 Beginning noncontrolling interests in the Operating Partnership $ 144,009 $ 144,802 Adjustment of noncontrolling interests in the Operating Partnership to fair value (33,427 ) (354 ) Conversions of Common Units to Common Stock (4,043 ) (511 ) Net income attributable to noncontrolling interests in the Operating Partnership 4,588 5,059 Distributions to noncontrolling interests in the Operating Partnership (5,167 ) (4,987 ) Total noncontrolling interests in the Operating Partnership $ 105,960 $ 144,009 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, 2018 2017 2016 Net income available for common stockholders $ 169,343 $ 182,873 $ 521,789 Increase in additional paid in capital from conversions of Common Units to Common Stock 4,043 511 3,057 Change from net income available for common stockholders and transfers from noncontrolling interests $ 173,386 $ 183,384 $ 524,846

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 the terms of definitive sales contracts or the sales comparison approach. 9. Disclosure About Fair Value of Financial Instruments - Continued 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.

The impaired real estate assets that were measured in the fourth quarter of 2018 and the third quarter of 2017 at fair values of $10.3 million and $5.9 million , respectively, and deemed to be Level 3 assets were valued based primarily on market-based inputs and our assumptions about the use of the assets, as observable inputs were not available. In the absence of observable inputs, we estimate the fair value of real estate using unobservable local and national industry market data such as comparable sales, sales contracts and appraisals to assist us in our estimation of fair value. Significant increases or decreases in any valuation inputs in isolation would result in a significantly lower or higher fair value measurement.

Warrants At December 31, 2018 and 2017 , 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 $1.85 , $1.76 and $2.50 for the years ended December 31, 2018 , 2017 and 2016 , respectively. Distributions declared in 2016 included a special cash distribution of $0.80 per unit declared in the quarter ended December 31, 2016 and paid January 10, 2017. The principal purpose of the special distribution was to distribute taxable capital gains associated with the sales of the Plaza assets in 2016. 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.

Disclosure of Compensation Related Costs, Share-based Payments [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. In 2018, the mix 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, 2018 2017 Outstanding stock options and warrants 611,518 655,822 Possible future issuance under equity incentive plans 2,188,696 2,404,131 2,800,214 3,059,953 Of the possible future issuance under the Company' long-term equity incentive plans at December 31, 2018 , no more than an additional 0.6 million shares can be in the form of restricted stock. During the years ended December 31, 2018 , 2017 and 2016 , we recognized $7.5 million , $6.7 million and $6.3 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, 2018 , there was $4.7 million of total unrecognized share-based compensation costs, which will be recognized over a weighted average remaining contractual term of 2.2 years. 11. Employee Benefit Plans - Continued - 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 2012 and 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 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 values of options granted during 2017 and 2016 were $6.72 and $4.61 , respectively, per option. The fair values of the options granted were determined at the grant dates using the following assumptions: 2017 2016 Risk free interest rate (1) 2.0 % 1.4 % Common stock dividend yield (2) 3.4 % 3.9 % Expected volatility (3) 19.5 % 19.7 % Average expected option life (years) (4) 5.75 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, 2015 687,228 $ 37.97 Granted 244,664 43.55 Canceled (14,743 ) 42.64 Exercised (330,034 ) 34.26 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 (1) (2) 596,518 $ 45.67 __________ (1) The outstanding options at December 31, 2018 had a weighted average remaining life of 6.8 years. (2) The Company had 303,674 options exercisable at December 31, 2018 with a weighted average exercise price of $43.67 , weighted average remaining life of 6.2 years and intrinsic value of $0.1 million . Of these exercisable options, 217,386 had exercise prices higher than the market price of our Common Stock at December 31, 2018 . 11. Employee Benefit Plans - Continued Cash received or receivable from options exercised was $1.9 million , $5.2 million and $13.4 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. The total intrinsic value of options exercised during the years ended December 31, 2018 , 2017 and 2016 was $0.4 million , $1.3 million and $4.8 million , respectively. The total intrinsic value of options outstanding at December 31, 2018 , 2017 and 2016 was $0.1 million , $3.9 million and $5.1 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 over four years. 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, 2015 204,720 $ 39.74 Awarded and issued (1) 72,698 43.59 Vested (2) (84,212 ) 37.76 Forfeited (4,225 ) 41.96 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 __________ (1) The weighted average fair value at grant date of time-based restricted stock issued during the years ended December 31, 2018 , 2017 and 2016 was $4.1 million , $3.2 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, 2018 , 2017 and 2016 was $3.2 million , $4.1 million and $3.7 million , respectively. Vested shares include those shares surrendered by employees to satisfy tax withholding obligations in connection with such vesting. 11. Employee Benefit Plans - Continued - 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 2018 , 2017 and 2016 was determined to be $40.81 , $49.59 and $41.37 , 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: 2018 2017 2016 Risk free interest rate (1) 2.3 % 1.6 % 0.9 % Common stock dividend yield (2) 3.9 % 3.5 % 4.1 % Expected volatility (3) 41.1 % 42.8 % 43.1 % __________ (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, 2015 195,303 $ 36.66 Awarded and issued (1) (3) 64,701 40.87 Vested (2) (3) (71,617 ) 36.50 Forfeited (4,663 ) 39.91 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 __________ (1) The fair value at grant date of total return-based restricted stock issued during the years ended December 31, 2018 , 2017 and 2016 was $3.2 million , $2.4 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, 2018 , 2017 and 2016 was $1.8 million , $5.6 million and $3.1 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 and 2016 amounts include 34,669 and 6,647 additional shares, respectively, that were issued at the end of the applicable measurement period because actual performance exceeded certain levels of performance. (4) Includes 13,707 shares that were forfeited at the end of the applicable measurement period because the applicable total return did not meet the target level. 11. Employee Benefit Plans - Continued 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, 2018 , 2017 and 2016 , we contributed $1.4 million , $1.4 million and $1.3 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 $1.8 million and $2.4 million at December 31, 2018 and 2017 , 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, 2018 2017 2016 Beginning deferred compensation liability $ 2,388 $ 2,451 $ 2,736 Mark-to-market adjustment to deferred compensation (in general and administrative expenses) (182 ) 492 222 Distributions from deferred compensation plans (357 ) (555 ) (507 ) Total deferred compensation liability $ 1,849 $ 2,388 $ 2,451 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 New York Stock Exchange on the five consecutive days preceding the last day of the quarter. In the years ended December 31, 2018 , 2017 and 2016 , the Company issued 38,951 , 33,278 and 27,773 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 , $0.2 million and $0.2 million in the years ended December 31, 2018 , 2017 and 2016 , 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 $1.26 , $1.37 and $0.99 per share in 2018 , 2017 and 2016 , 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 $4.3 billion and $2.3 billion , respectively, at December 31, 2018 and $4.1 billion and $2.3 billion , respectively, at December 31, 2017 . The tax basis of the Operating Partnership's assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $4.2 billion and $2.3 billion , respectively, at December 31, 2018 and $4.1 billion and $2.3 billion , respectively, at December 31, 2017 . During the years ended December 31, 2018 , 2017 and 2016 , 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, 2018 2017 2016 Current tax expense/(benefit): Federal $ 133 $ (177 ) $ (38 ) State 112 105 89 245 (72 ) 51 Deferred tax expense/(benefit): Federal (95 ) 223 (160 ) State (68 ) (9 ) 87 (163 ) 214 (73 ) Total income tax expense/(benefit) $ 82 $ 142 $ (22 ) The Company's net deferred tax liability was $0.2 million and $0.3 million as of December 31, 2018 and 2017 , 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, 2018 and 2017 , there were no unrecognized tax benefits. The Company is subject to federal, state and local income tax examinations by taxing authorities for 2015 through 2018 . The Company does not expect that the total amount of unrecognized benefits will materially change within the next year.

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, 2018 , three properties owned through a joint venture investment were consolidated. All intercompany transactions and accounts have been eliminated.
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	Beginning in 2018, 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, 2018 , a reserve of $0.5 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 $ 191.0 million , $ 184.4 million and $ 173.1 million for the years ended December 31, 2018 , 2017 and 2016 , 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. Expenditures directly related to the leasing of 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 for new leases or lease renewals are capitalized. Internal leasing costs, which consist primarily of compensation, benefits and other costs, such as legal fees related to leasing activities, that are incurred in connection with successfully obtaining leases of properties are also capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases, which generally are from three to 10 years. Estimated costs related to unsuccessful activities are expensed as incurred. 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, 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, customer relationships and other identifiable intangible assets and assumed liabilities. We assess fair value 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. 1. Description of Business and Significant Accounting Policies – Continued 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 events or changes in circumstances indicate that the carrying value may be impaired, 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
Rental and Other Revenues	Rental and Other Revenues 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 common area maintenance (“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.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts 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.
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.
Lease Incentives	Lease Incentives 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.
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, 2018 , properties that we wholly own were leased to 1,654 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Raleigh, Atlanta, Tampa and Nashville. Our customers engage in a wide variety of businesses. No single customer generated more than 5% of our consolidated revenues during 2018 . 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 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. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income/(loss) and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings. We account for terminated derivative instruments by recognizing the related accumulated 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 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 superseded the revenue recognition requirements under previous guidance, which we adopted as of January 1, 2018. Several updates have been issued subsequently that are intended to promote a more consistent interpretation and application of the principles outlined in the ASU. The ASU requires the use of a new five-step model to recognize revenue from contracts with customers. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We are also required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In analyzing our contracts with customers, we determined that the most material potential impact from the adoption of this ASU would be in how revenue is recognized for sales of real estate with post sale involvement. Prior to the adoption of this ASU, profit for such sales transactions was recognized and then reduced by the maximum exposure to loss related to the nature of the post sale involvement at the time of sale. Upon adoption of this ASU, any post sale involvement must be accounted for as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the post sale involvement performance obligation is satisfied, the portion of the sales price allocated to it will be recognized. We had no sales of real estate with continuing involvement during the year ended December 31, 2018 or prior periods; however, we will use such methodology for any future real estate sales with continuing involvement. Our internal controls with respect to accounting for such sales have been updated accordingly. Adoption of this ASU resulted in no other changes with respect to the timing of revenue recognition or internal controls related to contracts such as management, development and construction fees and transient parking income, all of which are not material to our Consolidated Financial Statements. As such, there is no cumulative-effect adjustment from the adoption of this ASU reflected in our Consolidated Financial Statements. The FASB issued an ASU that requires entities to show changes in total cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, restricted cash and restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning of period and end of period balances rather than presented as transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. We adopted the ASU as of January 1, 2018 with retrospective application to our Consolidated Statements of Cash Flows. Accordingly, our Consolidated Statements of Cash Flows present a reconciliation of the changes in cash and cash equivalents and restricted cash. The effect of the adoption resulted in a $55.9 million decrease in net cash used in investing activities for the year ended December 31, 2017 and a $12.4 million increase in net cash provided by investing activities for the year ended December 31, 2016 . The FASB issued an ASU that clarifies and narrows the definition of a business used in determining whether to account for a transaction as an asset acquisition or business combination. The guidance requires evaluation of the fair value of the assets acquired to determine if it is concentrated in a single identifiable asset or a group of similar identifiable assets. If so, the transferred assets would not be a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs. We adopted the ASU prospectively as of January 1, 2018. We expect that the majority of our future acquisitions would not meet the definition of a business; therefore, the related acquisition costs would be capitalized as part of the purchase price. The FASB issued an ASU that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance requires modification accounting if the value, vesting conditions or classification of the award changes. We adopted the ASU as of January 1, 2018 with no effect on our Consolidated Financial Statements. 1. Description of Business and Significant Accounting Policies – Continued The FASB issued an ASU that sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. In addition, the guidance requires lessors to capitalize and amortize only incremental direct leasing costs. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right of use asset and a lease liability for all leases with a term of greater than a year regardless of their classification. Leases with a term of a year or less will be accounted for in the same manner as operating leases today. The guidance supersedes previously issued guidance under ASC Topic 840 “Leases.” An entity may elect a package of practical expedients, which allows for the following: • An entity need not reassess whether any expired or existing contracts are or contain leases; • An entity need not reassess the lease classification for any expired or existing leases; and • An entity need not reassess initial direct costs for any existing leases. This package of practical expedients is available as a single election that must be consistently applied to all existing leases at the date of adoption. Furthermore, the FASB finalized an amendment that allows entities to present comparative periods, in the year of adoption, under ASC 840, which effectively allows for an initial date of adoption of January 1, 2019. The amendment also provides a practical expedient to lessors that removes the requirement to separate lease and non-lease components, provided certain conditions are met. Our analysis of our leases indicates that the lease component is the predominant component, that the timing and pattern of transfer of our material non-lease components (primarily cost recovery income) are the same as the lease components and the lease component, if it were accounted for separately, would be classified as an operating lease. As such, we believe the adoption of the ASU will not significantly change the accounting or the related internal controls for rental and other revenues from operating leases where we are the lessor, and that such leases will be accounted for in a manner similar to existing standards with the underlying leased asset being reported and recognized as a real estate asset. Upon the adoption of the ASU, we will no longer capitalize and amortize certain leasing related costs and instead will expense these costs as incurred. Such capitalized costs have averaged approximately $2.5 million annually. Leases where we are the lessee include primarily our operating ground leases. We currently believe that existing ground leases executed before the adoption date will continue to be accounted for as operating leases and the new guidance will not have a material impact on our recognition of ground lease expense or our results of operations. However, we will be required to recognize a right of use asset and a lease liability on our Consolidated Balance Sheets equal to the present value of the minimum lease payments required under each ground lease, which we believe will range from $31 million to $36 million . See Note 7 for information regarding our ground lease commitments. We will adopt the new ASU effective January 1, 2019 using the modified retrospective approach and will elect the use of all practical expedients provided by the ASU and related amendments as mentioned above. The FASB issued an ASU that eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item when the hedged item affects earnings. The ASU is required to be adopted in 2019 using a modified retrospective approach. We do not expect such adoption to have a material effect on our Consolidated Financial Statements. 1. Description of Business and Significant Accounting Policies – Continued The FASB issued an ASU that requires, among other things, the use of a new current expected credit loss ("CECL") model in determining our allowances for doubtful accounts with respect to accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable. The FASB recently finalized its proposal to exclude operating lease receivables from the scope of this ASU. As such, we do not expect the adoption of this ASU in 2020 to have a 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.
