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”). As of December 31, 2023, we owned or had an interest in 28.4 million rentable square feet of in-service properties, 1.6 million rentable square feet of office properties under development and development land with approximately 5.2 million rentable square feet of potential office build out. The Company is the sole general partner of the Operating Partnership. As of December 31, 2023, the Company owned all of the Preferred Units and 105.3 million, or 98.0%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.2 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 unitholder 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 2023, the Company redeemed 193,907 Common Units for a like number of shares of Common Stock and 7,294 Common Units for cash. These redemptions increased the percentage of Common Units owned by the Company from 97.8% as of December 31, 2022 to 98.0% as of December 31, 2023. 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. In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. As of December 31, 2023, we are involved with six entities we determined to be variable interest entities, one of which we are the primary beneficiary and is consolidated and five of which we are not the primary beneficiary and are not consolidated. We also own three properties through a joint venture investment that were deconsolidated effective January 1, 2023 (see Note 4). 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 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. As of December 31, 2023, 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 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 three Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy and capitalize only those costs associated with the portion under construction. We record liabilities for the performance of asset retirement activities when the obligation to perform such activities is probable even when uncertainty exists about the timing and/or method of settlement. Upon the acquisition of real estate assets accounted for as asset acquisitions, we assess the fair value of acquired tangible assets such as land, buildings and tenant improvements, intangible assets and liabilities such as above and below market leases, acquired in-place leases and other identifiable intangible assets and assumed liabilities. We allocate fair value on a relative basis based on estimated cash flow projections that utilize discount and/or capitalization rates as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. The above and below market rate portions of leases acquired in connection with property acquisitions are recorded in deferred leasing costs and in accounts payable, accrued expenses and other liabilities, respectively, at fair value and amortized into rental revenue over the remaining term of the respective leases as described below. Fair value is calculated as the present value of the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) our estimate of fair market lease rates for each corresponding in-place lease, using a discount rate that reflects the risks associated with the leases acquired and measured over a period equal to the remaining initial term of the lease for above-market leases and the remaining initial term plus the term of any renewal option that the customer would be economically compelled to exercise for below-market leases. In-place leases acquired are recorded at fair value in deferred leasing costs and 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. Assumed debt, if any, is recorded at fair value based on the present value of the expected future payments. Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the sale of the asset is probable, has been duly approved by the Company, a legally enforceable contract has been executed and the buyer’s due diligence period, if any, has expired. Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates With respect to assets classified as held for use, we perform an impairment analysis if our evaluation of events or changes in circumstances indicate that the carrying value may not be recoverable, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset’s carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete. If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and 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 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 determined an enforceable contract exists and collection of the consideration to which we are entitled in exchange for transferring the real estate is probable, 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 a separate performance obligation and the allocable sales price is recognized when the separate performance obligation is satisfied. Leases We generally lease our office properties to lessees in exchange for fixed monthly payments that cover rent, property taxes, insurance and certain cost recoveries, primarily common area maintenance (“CAM”). Our office properties that are under lease are primarily located in Atlanta, Charlotte, Dallas, Nashville, Orlando, Raleigh, Richmond and Tampa and are leased to a wide variety of lessees across many industries. Our leases are operating leases and mostly range from three line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Some of our leases are subject to annual changes in the Consumer Price Index (“CPI”). Although increases in the CPI are not estimated as part of our measurement of straight-line rental revenue, to the extent that actual CPI is greater or less than the CPI at lease commencement, the amount of rent recognized in a given year is affected accordingly. Some of our leases have termination and/or extension options. Termination options allow the customer to terminate the lease prior to the end of the lease term under certain circumstances. Termination options generally become effective halfway or further into the original lease term and require advance notification from the customer and payment of a termination fee that reimburses us for a portion of the remaining rent under the original lease term and the undepreciated lease inception costs such as commissions, tenant improvements and lease incentives. Termination fee income is recognized on a straight-line basis from the date of the executed termination agreement through lease expiration when the amount of the fee is determinable and collectability of the fee is reasonably assured. Our extension options generally require a re-negotiation with the customer at market rates. Initial direct costs, primarily commissions, related to the leasing of our office properties are included in deferred leasing costs and are stated at amortized cost. Such expenditures are part of the investment necessary to execute leases and are, therefore, classified as investment activities in the statement of cash flows. All leasing commissions paid to third parties and our in-house personnel for new leases or lease renewals are capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases. All other costs to negotiate or arrange a lease are expensed as incurred. Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign a lease, are capitalized in deferred leasing costs and amortized on a straight-line basis over the respective lease terms as a reduction of rental revenues. Lease related receivables, which include accounts receivable and accrued straight-line rents receivable, are reduced for credit losses. Such amounts are recognized as a reduction to rental and other revenues. We regularly evaluate the collectability of our lease related receivables. Our evaluation of collectability primarily consists of reviewing the credit quality of our customer, historical trends of the customer and changes in customer payment terms. We do not maintain a general reserve to estimate amounts that may not be collectible. If our assumptions regarding the collectability of lease related receivables prove incorrect, we could experience credit losses in excess of what was recognized in rental and other revenues. Discontinued Operations Properties that are sold or classified as held for sale are classified as discontinued operations provided that the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results. Interest expense is included in discontinued operations if a related loan securing the sold property is to be paid off or assumed by the buyer in connection with the sale. Investments in Unconsolidated Affiliates We account for our joint venture investments using the equity method of accounting when our interests represent a general partnership interest but substantive participating rights or substantive kick out rights have been granted to the limited partners or when our interests do not represent a general partnership interest and we do not control the major operating and financial policies of the investment. These investments are initially recorded at cost as investments in unconsolidated affiliates and are subsequently adjusted for our share of earnings and cash contributions and distributions. To the extent our cost basis at formation of the joint venture is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related assets and included in our share of equity in earnings of unconsolidated affiliates. Cash Equivalents We consider highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Restricted Cash Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as construction-related escrows, property disposition proceeds set aside and designated or intended to fund future tax-deferred exchanges of qualifying real estate investments and escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements. Redeemable Common Units and Preferred Units Limited partners holding Common Units other than the Company (“Redeemable Common Units”) have the right to put any and all of the Common Units to the Operating Partnership and the Company has the right to put any and all of the Preferred Units to the Operating Partnership in exchange for their liquidation preference plus accrued and unpaid distributions in the event of a corresponding redemption by the Company of the underlying Preferred Stock. Consequently, these Redeemable Common Units and Preferred Units are classified outside of permanent partners’ capital in the Operating Partnership’s accompanying balance sheets. The recorded value of the Redeemable Common Units is based on fair value at the balance sheet date as measured by the closing price of Common Stock on that date multiplied by the total number of Redeemable Common Units outstanding. The recorded value of the Preferred Units is based on their redemption value. Income Taxes The Company has elected and expects to continue to qualify as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”). A corporate REIT is a legal entity that holds real estate assets and, through the payment of dividends to stockholders, is generally permitted to reduce or avoid the payment of federal and state income taxes at the corporate level. To maintain qualification as a REIT, the Company is required to pay dividends to its stockholders equal to at least 90.0% of its annual REIT taxable income, excluding net capital gains. The partnership agreement requires the Operating Partnership to pay economically equivalent distributions on outstanding Common Units at the same time that the Company pays dividends on its outstanding Common Stock. Other than income taxes related to its taxable REIT subsidiary, the Operating Partnership does not reflect any federal income taxes in its financial statements since, as a partnership, the taxable effects of its operations are attributed to its partners. The Operating Partnership does record state income tax for states that tax partnership income directly. We conduct certain business activities through a taxable REIT subsidiary, as permitted under the Code. The taxable REIT subsidiary is subject to federal, state and local income taxes on its taxable income. We record provisions for income taxes based on its income recognized for financial statement purposes, including the effects of differences between such income and the amount recognized for tax purposes. Concentration of Credit Risk As of December 31, 2023, our consolidated properties were leased to approximately 1,500 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Atlanta, Charlotte, Nashville, Raleigh and Tampa . Our customers engage in a wide variety of businesses. No single customer generated more than 4% of our consolidated revenues during 2023. We maintain our cash and cash equivalents and our restricted cash at financial or other intermediary institutions. The combined account balances at each institution may exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. Additionally, from time to time in connection with tax-deferred 1031 transactions, our restricted cash balances may be commingled with other funds being held by any such intermediary institution, which would subject our balance to the credit risk of the institution. Derivative Financial Instruments We borrow funds at a combination of fixed and variable rates. Borrowings under our revolving credit facility and bank term loans bear interest at variable rates. Our long-term debt, which consists of secured and unsecured long-term financings, typically bears interest at fixed rates. Our interest rate risk management objectives are to generally limit 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 Interest rate swaps involve the receipt of variable rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income/(loss) and are subsequently reclassified into interest expense as interest payments are made on our debt. We account for terminated derivative instruments by recognizing the related accumulated other comprehensive income/(loss) balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated other comprehensive income/(loss) into interest expense 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 for 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 for common unitholders by the weighted Common Units outstanding - basic plus the dilutive effect of options and warrants, using the treasury stock method. Weighted Common Units outstanding - basic includes all of the Company’s unvested restricted stock where distributions received on such restricted stock are non-forfeitable. Recently Issued Accounting Standards The Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) that provides temporary optional expedients and exceptions to ease the financial reporting burdens related to the market transition from LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). These optional expedients and exceptions provide guidance on contract modifications and hedge accounting. We have completed the transition to SOFR rates for our applicable outstanding debt instruments with no material impact to our Consolidated Financial Statements. The FASB issued an ASU that will require enhanced segment disclosures, primarily regarding significant segment expenses. The ASU is required to be adopted in our 2024 Annual Report and applied retrospectively to all prior periods presented in the financial statements. We do not expect such adoption to have a material effect on our Notes to Consolidated Financial Statements.

Real Estate [Abstract]
Real Estate Assets	Real Estate Assets Acquisitions During 2023, we acquired land in Raleigh for a purchase price, including capitalized acquisition costs, of $2.7 million. During 2022, we acquired SIX50 at Legacy Union, a 367,000 square foot trophy office building in Charlotte’s Uptown CBD submarket, for a net purchase price of $198.0 million. The assets acquired and liabilities assumed were recorded at relative fair value as determined by management, with the assistance of third party specialists, based on information available at the acquisition date and on current assumptions as to future operations. During 2022, we also acquired land in Charlotte for an aggregate purchase price, including capitalized acquisition costs, of $27.0 million. During 2021, we acquired a portfolio of real estate assets from PAC. The portfolio consists of the following assets: Asset Market Submarket/BBD Square Footage 150 Fayetteville Raleigh CBD 560,000 CAPTRUST Towers Raleigh North Hills 300,000 Capitol Towers Charlotte SouthPark 479,000 Morrocroft Centre Charlotte SouthPark 291,000 Galleria 75 Redevelopment Site Atlanta Cumberland/Galleria Our total purchase price, net of closing credits and cash acquired, was $653.6 million, including $4.5 million of capitalized acquisition costs. The acquisition included the assumption of four secured loans (see Note 6). The assets acquired and liabilities assumed were recorded at relative fair value as determined by management, with the assistance of third party specialists, based on information available at the acquisition date and on current assumptions as to future operations. The following table sets forth a summary of the relative fair value of the material assets acquired and liabilities assumed relating to this acquisition: Amount Recorded at Acquisition Real estate assets (1) $ 593,039 Acquisition-related intangible assets (in deferred financing and leasing costs) (1) $ 61,126 Right of use asset (in prepaid expenses and other assets) (1) $ 8,440 Mortgages and notes payable $ (403,000) Debt issuance costs (in mortgages and notes payable) (1) $ 3,473 Acquisition-related intangible liabilities (in accounts payable, accrued expenses and other liabilities) (1) $ (7,174) Lease liability (in accounts payable, accrued expenses and other liabilities) (1) $ (5,310) __________ (1) Included in purchase price. During 2021, we acquired various development land parcels in Nashville for an aggregate purchase price, including capitalized acquisition costs, of $74.1 million. The $16.0 million purchase price for one of the acquired parcels was fully paid in or prior to the second quarter of 2023. Duri ng 2021, we also acquired our joint venture partner’s 75.0% interest in our Highwoods DLF Forum, LLC joint venture (the “Forum”), which owned five buildings in Raleigh encompassing 636,000 rentable square feet, for a purchase price of $131.3 million. We previously accounted for our 25.0% interest in this joint venture using the equity method of accounting. The assets and liabilities of the joint venture are now wholly owned and we have determined the acquisition constitutes an asset purchase. As such, because the Forum is not a variable interest entity, we allocated our previously held equity interest at historical cost along with the consideration paid and acquisition costs to the assets acquired and liabilities assumed. The assets acquired and liabilities assumed were recorded at relative fair value as determined by management, with the assistance of third party specialists, based on information available at the acquisition date and on current assumptions as to future operations. Dispositions During 2023, we sold a total of four buildings and various land parcels in Nashville, Raleigh and Tampa for an aggregate sales price of $103.8 million and recorded aggregate gains on disposition of property of $47.8 million. During 2022, we sold a total of five office buildings and various land parcels in Atlanta, Greensboro, Richmond and Tampa for an aggregate sales price of $133.5 million (before closing credits to buyers of $1.1 million) and recorded aggregate gains on disposition of property of $63.5 million. During 2021, we sold a total of 13 office buildings and various land parcels in Atlanta, Memphis, Raleigh, Richmond and Tampa for an aggregate sales price of $384.6 million (before closing credits to buyers of $6.9 million) and recorded aggregate gains on disposition of property of $172.8 million. Seller Financed Transaction During 2023, we sold a land parcel in Tampa for an aggregate sales price of $21.0 million. In connection with this disposition, we received cash of $2.0 million and provided $19.0 million of non-recourse seller financing in the form of a two-year, interest-only first mortgage that bears interest at SOFR plus 100 basis points. We have deemed repayment of the mortgage to be not probable primarily because the seller financing represents a significant portion of the aggregate sales price and, since the seller financing is non-recourse, our only remedy in the event of a default would be to foreclose on the asset. As a result, the disposition does not meet the contract criteria to be recognized as a sale. Until such time as the contract criteria are met, we will continue to account for the land parcel as land held for development on our Consolidated Balance Sheets, and the mortgage associated with the seller financing will not be recorded on our Consolidated Balance Sheets. The cash received at closing is recorded as a nonrefundable deposit in accounts payable, accrued expenses and other liabilities on our Consolidated Balance Sheets as of December 31, 2023. Impairments We recorded the following impairment charges in 2022: • During the third quarter of 2022, we recorded an impairment charge of $1.5 million to lower the carrying amount of a land parcel to its estimated fair value less costs to sell; and •

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 $18.9 million and $2.7 million as of December 31, 2023 and 2022, respectively. The following table sets forth our ownership in unconsolidated affiliates as of December 31, 2023: Joint Venture Location Ownership Highwoods-Markel Associates, LLC Richmond 50.0% Granite Park Six JV, LLC Dallas 50.0% GPI 23 Springs JV, LLC Dallas 50.0% M+O JV, LLC Dallas 50.0% Midtown East Tampa, LLC Tampa 50.0% Brand/HRLP 2827 Peachtree, LLC Atlanta 50.0% Plaza Colonnade, Tenant-in-Common Kansas City 50.0% Kessinger/Hunter & Company, LC Kansas City 26.5% - Highwoods-Markel Associates, LLC (“Markel joint venture”) In 1999, we formed a joint venture with Markel Corporation in which we own a 50.0% interest. The Markel joint venture was consolidated as of December 31, 2022 because we controlled the major operating and financial policies of the entity. Effective January 1, 2023, the agreement governing the joint venture was modified to require the consent of both partners for major operating and financial policies of the entity. As a result, the Markel joint venture was deconsolidated effective January 1, 2023, and this joint venture is now accounted for using the equity method of accounting. We recognized a gain on deconsolidation of $11.8 million related to adjusting our retained interest in the joint venture to fair value. The assets of the Markel joint venture can only be used to settle obligations of the joint venture, and its creditors have no recourse to our wholly owned assets. During 2021, prior to the deconsolidation, the Markel joint venture sold land in Richmond for a sale price of $3.0 million and recorded gain on disposition of property of $1.3 million. - Granite Park Six JV, LLC/ GPI 23 Springs JV, LLC (“Granite Park Six joint venture”/“23Springs joint venture”) During 2022, we entered the Dallas market through the formation of two joint ventures with Granite Properties (“Granite”) to develop Granite Park Six and 23Springs. In connection with the formation, we agreed to contribute our 50.0% share of the equity required to fund each development project. The Granite Park Six joint venture has an anticipated total investment of $200.0 million and the 23Springs joint venture has an anticipated total investment of $460.0 million. As of December 31, 2023, we have fully funded our share of the equity for the Granite Park Six joint venture and have funded $75.6 million of our share of the equity for the 23Springs joint venture. The Granite Park Six joint venture obtained a construction loan for $115.0 million, with an interest rate of SOFR plus 394 basis points and a maturity date of January 2026. In connection with this loan, the Granite Park Six joint venture obtained an interest rate hedge contract that effectively caps the underlying SOFR rate at 3.5% with respect to $95.2 million of any outstanding amounts. The cap expires in July 2024. As of December 31, 2023, $54.9 million was drawn on this loan. The 23Springs joint venture obtained a construction loan for $265.0 million, with an interest rate of SOFR plus 355 basis points and a maturity date of March 2026. In connection with this loan, the 23Springs joint venture obtained an interest rate hedge contract that effectively caps the underlying SOFR rate at 3.5% with respect to $83.0 million of any outstanding amounts. The cap expires in April 2024. As of December 31, 2023, no amounts were drawn on this loan. We determined that we have a variable interest in both the Granite Park Six and 23Springs joint ventures primarily because the entities were designed to pass along interest rate risk, equity price risk and operation risk to us and Granite as equity holders. The joint ventures were further determined to be variable interest entities as they require additional subordinated financial support in the form of loans because the initial equity investments provided by us and Granite are not sufficient to finance the planned investments and operations. We concluded we do not have the power to direct matters that most significantly impact the activities of either entity and therefore do not qualify as the primary beneficiary. Accordingly, the entities are not consolidated. As of December 31, 2023, our risk of loss with respect to these arrangements was limited to the carrying value of each investment balance. Our investment balances were $41.9 million and $78.7 million as of December 31, 2023 for the Granite Park Six and 23Springs joint ventures, respectively. The assets of the Granite Park Six and 23Springs joint ventures can only be used to settle obligations of the respective joint venture, and their creditors have no recourse to our wholly owned assets. - M+O JV, LLC (“McKinney & Olive joint venture”) During 2022, we expanded our Dallas market presence by acquiring McKinney & Olive through the formation of another joint venture with Granite in which we own a 50.0% interest. The McKinney & Olive joint venture has an anticipated total investment of $394.7 million. As part of the transaction, the McKinney & Olive joint venture assumed a secured loan recorded at fair value of $137.0 million, with a stated interest rate of 4.5% and an effective interest rate of 5.3%, that is scheduled to mature in July 2024. The remainder of the purchase price paid by the McKinney & Olive joint venture was funded with $80.0 million of short-term preferred equity contributed by us and $86.4 million of common equity contributed by each of Granite and us. During 2023, we and Granite each contributed an additional $40.0 million of common equity to the McKinney & Olive joint venture. Such proceeds were then used by the joint venture to redeem our $80.0 million short-term preferred equity investment in full. Prior to the redemption, we received monthly distributions on the preferred equity at a rate of SOFR plus 350 basis points. We determined that we have a variable interest in the McKinney & Olive joint venture primarily because the entity was designed to pass along interest rate risk, equity price risk and operation risk to us and Granite as equity holders. The McKinney & Olive joint venture was further determined to be a variable interest entity as it requires additional subordinated financial support in the form of a loan because the initial equity investments by us and Granite, including the additional preferred equity provided by us, are not sufficient to finance its planned investments and operations. We concluded we do not have the power to direct matters that most significantly impact the activities of the entity and therefore do not qualify as the primary beneficiary. Accordingly, the entity is not consolidated. As of December 31, 2023, our risk of loss with respect to this arrangement was $118.6 million, which represents the carrying value of our investment balance. The redemption of the preferred equity during 2023 was a reconsideration event that did not change our initial conclusion that the McKinney & Olive joint venture is a variable interest entity of which were are not the primary beneficiary. As such, the entity remains unconsolidated. The assets of the McKinney & Olive joint venture can only be used to settle obligations of the joint venture, and its creditors have no recourse to our wholly owned assets. - Midtown East Tampa, LLC (“Midtown East joint venture”) During 2022, we formed a joint venture with The Bromley Companies (“Bromley”) in which we own a 50.0% interest to construct Midtown East, a multi-customer office development project located in the mixed-use Midtown Tampa project in Tampa’s Westshore submarket. Upon completion, the Midtown East joint venture will own 143,000 square feet of an overall 432,000 square foot tower. The rest of Midtown East will be owned by and serve as the future headquarters of Tampa Electric and Peoples Gas. The total anticipated investment for the Midtown East joint venture’s share of the overall project is $83.0 million. In connection with the formation, we agreed to contribute our 50.0% share of the equity required to fund the development project, $13.7 million of which was funded as of December 31, 2023. We also committed to provide a $52.3 million interest-only secured construction loan to the Midtown East joint venture that is scheduled to mature on the third anniversary of completion. The loan bears interest at SOFR plus 450 basis points. As of December 31, 2023, no amounts were drawn on this loan. We determined that we have a variable interest in the Midtown East joint venture primarily because the entity was designed to pass along interest rate risk, equity price risk and operation risk to us, both as a debt and an equity holder, and to Bromley as an equity holder. The Midtown East joint venture was further determined to be a variable interest entity as it requires additional subordinated financial support in the form of a loan because the initial equity investments provided by us and Bromley are not sufficient to finance its planned investments and operations. We concluded we do not have the power to direct matters that most significantly impact the activities of the entity and therefore do not qualify as the primary beneficiary. Accordingly, the entity is not consolidated. As of December 31, 2023, our risk of loss with respect to this arrangement was limited to the carrying value of the investment balance of $13.6 million as no amounts were outstanding under the loan. The assets of the Midtown East joint venture can only be used to settle obligations of the joint venture, and its creditors have no recourse to our wholly owned assets. - Brand/HRLP 2827 Peachtree LLC (“2827 Peachtree joint venture”) During 2021, we formed a joint venture with Brand Properties, LLC (“Brand”) to construct 2827 Peachtree, a 135,000 square foot, multi-customer office building located in Atlanta’s Buckhead submarket. The 2827 Peachtree joint venture has an anticipated total investment of $79.0 million. At closing, we agreed to contribute cash of $13.3 million, which has been fully funded, in exchange for a 50.0% interest in the 2827 Peachtree joint venture. Brand contributed land valued at $7.7 million and cash of $5.6 million in exchange for the remaining 50.0% interest. We have provided a $52.8 million interest-only secured construction loan to the 2827 Peachtree joint venture that is scheduled to mature in December 2024 with an option to extend for one year. The loan bears interest at SOFR plus 310 basis points. As of December 31, 2023, $46.9 million was drawn on this loan. We determined that we have a variable interest in the 2827 Peachtree joint venture primarily because the entity was designed to pass along interest rate risk, equity price risk and operation risk to us, both as a debt and an equity holder, and to Brand as an equity holder. The 2827 Peachtree joint venture was further determined to be a variable interest entity as it requires additional subordinated financial support in the form of a loan because the initial equity investments provided by us and Brand are not sufficient to finance its planned investments and operations. We concluded we do not have the power to direct matters that most significantly impact the activities of the entity and therefore do not qualify as the primary beneficiary. Accordingly, the entity is not consolidated. As of December 31, 2023, our risk of loss with respect to this arrangement was $60.3 million, which consists of the $13.4 million carrying value of our investment balance plus the $46.9 million outstanding balance of the loan. The outstanding balance on the loan is recorded in investments in and advances to unconsolidated affiliates on our Consolidated Balance Sheets. The assets of the 2827 Peachtree joint venture can only be used to settle obligations of the joint venture, and its creditors have no recourse to our wholly owned assets. - Other Activities 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, 2023, 2022 and 2021, we recognized $1.0 million, $0.6 million and $1.6 million, respectively, of development/construction, management and leasing fees from our unconsolidated joint ventures. Consolidated Affiliate - HRLP MTW, LLC (“Midtown West joint venture”) In 2019, we and Bromley formed a joint venture to construct Midtown West, a 152,000 square foot, multi-customer office building located in the mixed-use Midtown Tampa project in Tampa’s Westshore submarket. At closing, we agreed to contribute cash of $20.0 million, which has been fully funded, in exchange for an 80.0% interest in the Midtown West joint venture, and Bromley contributed land valued at $5.0 million in exchange for the remaining 20.0% interest. We also provided a $46.3 million interest-only secured construction loan to the Midtown West joint venture. All of the amounts outstanding under this loan were repaid in the fourth quarter of 2023. During 2023, the Midtown West joint venture obtained a $45.0 million, five-year secured mortgage loan from a third party lender, with an effective fixed rate of 7.29%. This loan is scheduled to mature in November 2028. The joint venture incurred $0.8 million of debt issuance costs, which will be amortized over the term of the loan. The net proceeds were used by the joint venture to repay in full the secured construction loan we provided, as discussed above. We determined that we have a variable interest in the Midtown West joint venture primarily because the entity was designed to pass along interest rate risk, equity price risk and operation risk to us, both as a debt and an equity holder, and to Bromley as an equity holder. The Midtown West joint venture was further determined to be a variable interest entity as it requires additional subordinated financial support in the form of a loan because the initial equity investments provided by us and Bromley are not sufficient to finance its planned investments and operations. We, as majority owner and managing member and through our control rights as set forth in the joint venture’s governance documents, were determined to be the primary beneficiary as we have both the power to direct the activities that most significantly affect the entity (primarily lease rates, property operations and capital expenditures) and significant economic exposure through our equity investment. The joint venture obtaining a loan from a third party during 2023, as discussed above, was a reconsideration event that did not change our initial conclusion that the Midtown West joint venture is a variable interest entity of which we are the primary beneficiary. As such, the entity remains consolidated and all intercompany transactions and accounts are eliminated. The following table sets forth the assets and liabilities of the Midtown West joint venture included on our Consolidated Balance Sheets: December 31, 2023 2022 Net real estate assets $ 60,410 $ 59,854 Cash and cash equivalents $ 1,096 $ 1,009 Restricted cash $ 2,260 $ — Accounts receivable $ 31 $ 1,490 Accrued straight-line rents receivable $ 5,041 $ 1,921 Deferred leasing costs, net $ 2,783 $ 2,677 Prepaid expenses and other assets $ 124 $ 153 Mortgages and notes payable, net $ 44,192 $ — Accounts payable, accrued expenses and other liabilities $ 2,872 $ 1,212 The assets of the Midtown West joint venture can only be used to settle obligations of the joint venture, and its creditors have no recourse to our wholly owned assets. Joint Venture Rights and Obligations With respect to some of our joint ventures, we have a right to buy, and our joint venture partner has a right to sell to us, such joint venture partner’s interest under certain circumstances for fair market value (less estimated costs to sell) during various timeframes in the future. For our Granite Park Six joint venture, such rights are exercisable during the two-year period commencing on the 10th anniversary of the completion date. For each of our 23Springs and McKinney & Olive joint ventures, such rights are exercisable during the two-year period commencing on the 12th anniversary of the stabilization date of 23Springs. For our 2827 Peachtree joint venture, such rights are exercisable during the two-year period commencing on the earlier of: (1) the stabilization date; (2) the seventh anniversary of the completion date; and (3) the maturity of the loan provided by us to the joint venture. For our Midtown West joint venture, our right to buy our partner’s interest is exercisable during the two-year period commencing on the seventh anniversary of the completion date, and our partner’s right to sell its interest to us is exercisable during the period commencing on the stabilization date and ending on the ninth anniversary of the completion date. In addition to the foregoing, with respect to our Granite Park Six, 23Springs and Midtown West joint ventures, our joint venture partner has the right to receive additional consideration from us or the joint venture under certain circumstances if and to the extent the internal rate of return on the applicable development project exceeds certain thresholds.

The following table sets forth scheduled future principal payments, including amortization, due on our mortgages and notes payable as of December 31, 2023: Years Ending December 31, Amount 2024 $ 6,944 2025 27,156 2026 206,922 2027 458,976 2028 699,168 Thereafter 1,831,779 Less-unamortized debt issuance costs (17,739) $ 3,213,206 As of December 31, 2023,our $750.0 million unsecured revolving credit facility was scheduled to mature in March 2025. The interest rate on our revolving credit facility was SOFR plus a related spread adjustment of 10 basis points and a borrowing spread of 85 basis points, based on current credit ratings. The annual facility fee was 20 basis points. The interest rate and facility fee were based on the higher of the publicly announced ratings from Moody’s Investors Service or Standard & Poor’s Ratings Services. We were entitled to a temporary reduction in the interest rate of one basis point provided we meet certain sustainability goals with respect to the ongoing reduction of greenhouse gas emissions. As of December 31, 2023, there was $20.0 million outstanding under our revolving credit facility and $0.9 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 as of December 31, 2023 was $729.1 million. During 2023, the Operating Partnership issued $350.0 million aggregate principal amount of 7.650% notes due February 2034, less original issuance discount of $4.6 million. These notes were priced to yield 7.836%. Previously during 2023, we obtained an aggregate of $200.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at 4.498%. Upon the subsequent issuance of the notes, we terminated the forward-starting swaps and paid cash upon settlement. The unrealized loss of $0.5 million will be classified to interest expense as interest payments are made on the debt. Underwriting fees and other expenses totaled $3.2 million and will be amortized over the term of the notes. The net proceeds from the issuance were used: (1) to prepay, without penalty, a $200.0 million unsecured bank term loan that was scheduled to mature in October 2024; (2) to repay amounts outstanding under our revolving credit facility; and (3) for general corporate purposes. We recorded $0.6 million of loss on debt extinguishment related to the term loan prepayment. During 2023, we obtained a $200.0 million, five-year secured mortgage loan from a third party lender, with an effective fixed interest rate of 5.69%. This loan is scheduled to mature in April 2028. We incurred $1.3 million of debt issuance costs, which will be amortized over the term of the loan. During 2022, we obtained a $200.0 million, two-year unsecured bank term loan that was originally scheduled to mature in October 2024. This loan was prepaid in full without penalty during the fourth quarter of 2023. The interest rate, based on current credit ratings, was SOFR plus a related spread adjustment of 10 basis points and a borrowing spread of 95 basis points. The interest rate was based on the higher of the publicly announced ratings from Moody’s Investors Service or Standard & Poor’s Ratings Services. We were entitled to a temporary reduction in the interest rate of one basis point provided we met certain sustainability goals with respect to the ongoing reduction of greenhouse gas emissions. We used the additional $200.0 million of borrowings, together with available cash and borrowings under our revolving credit facility, to prepay without penalty $250.0 million principal amount of 3.625% unsecured notes that were scheduled to mature in January 2023. During 2022, we modified our other $200.0 million unsecured bank term loan to extend the maturity date from November 2022 to May 2026. As part of this modification, we also obtained a $150.0 million delayed-draw term loan, which was drawn in its entirety in the third quarter of 2022, that is scheduled to mature in May 2027. The interest rate, based on current credit ratings, is SOFR plus a related spread adjustment of 10 basis points and a borrowing spread of 95 basis points. The interest rate is based on the higher of the publicly announced ratings from Moody’s Investors Service or Standard & Poor’s Ratings Services. Subject to written consent of the lenders, we may elect to amend this term loan no later than May 15, 2024 to provide that the interest rate may be adjusted upward or downward by up to 2.5 basis points subject to satisfaction of certain to-be-determined sustainability goals with respect to the ongoing reduction of greenhouse gas emissions. We incurred $2.7 million of debt issuance costs, which are being amortized along with certain existing unamortized debt issuance costs over the remaining term of our modified term loan. During 2021, in conjunction with the acquisition of real estate assets from PAC, we assumed four secured mortgage loans recorded at fair value of $403 million in the aggregate, with a weighted average effective interest rate of 3.54% and a weighted average maturity of 10.7 years. We incurred $3.5 million of debt issuance costs related to these assumptions, which will be amortized over the remaining terms of the loans. During 2021, we also obtained a $200.0 million, six six During 2021, we prepaid without penalty the remaining $150.0 million principal amount of 3.20% unsecured notes that was scheduled to mature in June 2021. We recorded $0.1 million of loss on debt extinguishment related to this prepayment. We previously 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 fixed the underlying one-month LIBOR rate at a weighted average rate of 1.693%. During 2022, these interest rate swaps expired. We are currently in compliance with financial covenants with respect to our consolidated debt. 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 $35.0 million with respect to other loans in some circumstances. The Operating Partnership has $2,140.2 million carrying amount of various notes outstanding as detailed in the table above. 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 within one year from February 6, 2024 (the date of issuance of the annual financial statements) and the adequacy of our estimated cash flows from operating activities and other available financing sources to meet these needs. Importantly, we have no scheduled debt maturities during such one-year period. We have concluded it is probable we will meet these short-term liquidity requirements through a combination of the following: • available cash and cash equivalents; • cash flows from operating activities; • issuance of debt securities by the Operating Partnership; • 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 wholly-owned and joint venture development and significant building and tenant improvement projects was $9.0 million, $4.0 million and $9.6 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Lease and Contractual Commitments We have $204.3 million of lease and contractual commitments as of December 31, 2023. Lease and contractual commitments represent commitments under signed leases and contracts for operating properties (excluding tenant-funded tenant improvements), contracts for development/redevelopment projects and unfunded joint venture equity contributions agreed to at formation, of which $50.7 million was recorded on our Consolidated Balance Sheet as of December 31, 2023. Contingent Consideration We had $0.8 million of contingent consideration related to a parcel of acquired development land as of both December 31, 2023 and 2022. The contingent consideration 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 in our Consolidated Financial Statements. Litigation, Claims and Assessments From time to time, we are 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 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. Joint Venture Buyout Rights and Obligations With respect to certain of our joint ventures, we have a right to buy, and our joint venture partner has a right to sell to us, such joint venture partner's interest under certain circumstances for fair market value (less estimated costs to sell) at various timeframes in the future. See Note 4. In addition, with respect to certain of our joint ventures, our joint venture partner has a right to receive additional consideration from us or the joint venture under certain circumstances if and to the extent the internal rate of return on the applicable development project exceeds certain thresholds. See Note 4.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Noncontrolling Interests in Consolidated Affiliates As of December 31, 2023, our noncontrolling interests in consolidated affiliates relate to our joint venture partner’s 20.0% interest in the Midtown West joint venture. See Note 4. 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, 2023 2022 Beginning noncontrolling interests in the Operating Partnership $ 65,977 $ 111,689 Adjustment of noncontrolling interests in the Operating Partnership to fair value (10,152) (39,502) Conversions of Common Units to Common Stock (4,795) (1,251) Redemptions of Common Units (163) (3,763) Net income attributable to noncontrolling interests in the Operating Partnership 3,164 3,670 Distributions to noncontrolling interests in the Operating Partnership (4,511) (4,866) Total noncontrolling interests in the Operating Partnership $ 49,520 $ 65,977 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, 2023 2022 2021 Net income available for common stockholders $ 146,230 $ 156,572 $ 310,791 Increase in additional paid in capital from conversions of Common Units to Common Stock 4,795 1,251 15,076 Redemptions of Common Units 163 3,763 — Change from net income available for common stockholders and transfers from noncontrolling interests $ 151,188 $ 161,586 $ 325,867

Disclosure About Fair Value of Financial Instruments	Dec. 31, 2023
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. Our Level 2 liabilities include the fair value of our mortgages and notes payable and 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 are significant to the fair value of the assets or liabilities. Our Level 3 assets include any real estate assets recorded at fair value on a non-recurring basis as a result of our quarterly impairment analysis, which are valued using unobservable local and national industry market data such as comparable sales, appraisals, brokers’ opinions of value and/or the terms of definitive sales contracts. Significant increases or decreases in any valuation inputs in isolation would result in a significantly lower or higher fair value measurement. The following table sets forth our assets and liabilities and the Company’s noncontrolling interests in the Operating Partnership that are measured or disclosed at fair value within the fair value hierarchy: Level 1 Level 2 Total Quoted Prices Significant Observable Inputs Fair Value as of December 31, 2023: Assets: Mortgages and notes receivable, at fair value (1) $ 4,795 $ — $ 4,795 Marketable securities of non-qualified deferred compensation plan (in prepaid expenses and other assets) 2,294 2,294 — Total Assets $ 7,089 $ 2,294 $ 4,795 Noncontrolling Interests in the Operating Partnership $ 49,520 $ 49,520 $ — Liabilities: Mortgages and notes payable, net, at fair value (1) $ 2,927,330 $ — $ 2,927,330 Non-qualified deferred compensation obligation (in accounts payable, accrued expenses and other liabilities) 2,294 2,294 — Total Liabilities $ 2,929,624 $ 2,294 $ 2,927,330 Fair Value as of December 31, 2022: Assets: Mortgages and notes receivable, at fair value (1) $ 1,051 $ — $ 1,051 Marketable securities of non-qualified deferred compensation plan (in prepaid expenses and other assets) 2,564 2,564 — Total Assets $ 3,615 $ 2,564 $ 1,051 Noncontrolling Interests in the Operating Partnership $ 65,977 $ 65,977 $ — Liabilities: Mortgages and notes payable, net, at fair value (1) $ 2,832,973 $ — $ 2,832,973 Non-qualified deferred compensation obligation (in accounts payable, accrued expenses and other liabilities) 2,564 2,564 — Total Liabilities $ 2,835,537 $ 2,564 $ 2,832,973 __________ (1) Amounts are not recorded at fair value on our Consolidated Balance Sheets as of December 31, 2023 and 2022. At various points throughout 2022, there were Level 3 impaired real estate assets resulting from the shortened hold period assumptions for certain assets in Pittsburgh, which included the following: • a land parcel measured at a fair value of $1.7 million in the third quarter of 2022. This impairment resulted from the changes in our assumptions about the use of the asset as a result of our plan to exit the Pittsburgh market and was calculated using broker opinions of value, as observable inputs were not available; and • EQT Plaza, an in-service office building measured at a fair value of $57.4 million in the second quarter of 2022. This impairment resulted from the shortened hold period assumptions for the asset as a result of our plan to exit the Pittsburgh market. The estimated fair value was calculated using broker opinions of value, which incorporate an income approach, as observable inputs were not available. Key assumptions used in the impairment calculation were estimated selling costs of 3.5% (including seller’s share of anticipated transfer taxes), the high end of an estimated discount rate ranging from 13.2% to 16.2% and an estimated terminal capitalization rate of 8.0%.

Equity [Abstract]
Equity	Equity Common Stock Issuances During 2023, we entered into separate equity distribution agreements in which the Company may offer and sell up to $300.0 million in aggregate gross sales price of shares of Common Stock. There were no shares issued under these agreements in 2023. During 2022, the Company issued 130,011 shares of Common Stock under its equity distribution agreements at an average gross sales price of $46.50 per share and received net proceeds, after sales commissions, of $6.0 million. As of December 31, 2023, the Company had 94.3 million remaining shares of Common Stock authorized to be issued under its charter. Common Stock Dividends Dividends of the Company declared per share of Common Stock were $2.00, $2.00 and $1.96 for the years ended December 31, 2023, 2022 and 2021, respectively. The following table sets forth the Company’s estimated taxability to the common stockholders of dividends per share for federal income tax purposes: Year Ended December 31, 2023 2022 2021 Ordinary dividend $ 1.58 $ 1.82 $ 1.87 Capital gains 0.42 0.18 0.09 Total $ 2.00 $ 2.00 $ 1.96 The Company’s tax returns have not been examined by the Internal Revenue Service (“IRS”) and, therefore, the taxability of dividends is subject to change.

Warrants As of both December 31, 2023 and 2022, 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 were $2.00, $2.00 and $1.96 for the years ended December 31, 2023, 2022 and 2021, respectively. Redeemable Common Units Generally, the Operating Partnership is obligated to redeem each Redeemable Common Unit at the request of the holder thereof for cash equal to the value of one share of Common Stock based on the average of the market price for the 10 trading days immediately preceding the notice date of such redemption, provided that the Company, at its option, may elect to acquire any such Redeemable Common Unit presented for redemption for cash or one share of Common Stock. When a holder redeems a Redeemable Common Unit for a share of Common Stock or cash, the Company’s share in the Operating Partnership will be increased. The Common Units owned by the Company are not redeemable.

Share-Based Payment Arrangement [Abstract]
Employee Benefit Plans	Employee Benefit Plans Officer, Management and Director Compensation Programs Officers of the Company participate in an annual non-equity incentive program pursuant to which they are eligible to earn cash payments based on a percentage of their annual base salary in effect for December of the applicable year. Under this component of our executive compensation program, officers are eligible to earn additional cash compensation generally 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 140% 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%. 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 5% to 30% of annual base salary. These amounts are also accrued and expensed in the year earned, but are typically paid early in the following year. The Company’s officers are eligible to receive a mix of long-term equity incentive awards on or about March 1 of each year. Prior to 2018, the mix generally consisted of stock options, time-based restricted stock and total return-based restricted stock. Since 2018, the mix has consisted of time-based restricted stock and total return-based restricted stock. Time-based restricted stock grants are also made annually to directors and certain other employees. Dividends received on restricted stock are non-forfeitable and are paid at the same rate and on the same date as on shares of Common Stock, except that, with respect to shares of total return-based restricted stock issued to the Company’s chief executive officer, dividends accumulate and are payable only if and to the extent the shares vest. Dividends paid on subsequently forfeited shares are expensed. Additional shares of total return-based restricted stock may be issued at the end of the applicable measurement periods if and to the extent actual performance exceeds certain levels of performance. Such additional shares, if any, would be fully vested when issued. No expense is recorded for additional shares of total return-based restricted stock that may be issued at the end of the applicable measurement period since that possibility is reflected in the grant date fair value. The following table sets forth the number of shares of Common Stock reserved for future issuance under the Company’s long-term equity incentive plans: December 31, 2023 2022 Outstanding stock options and warrants 527,067 527,067 Possible future issuance under equity incentive plans 2,537,816 2,817,293 3,064,883 3,344,360 Of the possible future issuance under the Company’s long-term equity incentive plans as of December 31, 2023, no more than an additional 0.5 million shares can be in the form of restricted stock. During the years ended December 31, 2023, 2022 and 2021, we recognized share-based compensation expense of $7.0 million, $7.6 million and $8.6 million, respectively. Because REITs generally do not pay income taxes, we do not realize tax benefits on share-based payments. As of December 31, 2023, there was $4.0 million of total unrecognized share-based compensation costs, which will be recognized over a weighted average remaining contractual term of 2.0 years. - Stock Options Outstanding stock options vest ratably on an annual basis over four years and expire after 10 years. All stock options have an exercise price equal to the last reported stock price of our Common Stock on the New York Stock Exchange (“NYSE”) on the last trading day prior to grant. The value of all options as of the date of grant is calculated using the Black-Scholes option-pricing model and is amortized over the respective vesting period or the service period, if shorter, for employees who are or will become eligible under the Company’s retirement plan. The following table sets forth stock option activity: Options Outstanding Number of Options Weighted Average Exercise Price Stock options outstanding as of December 31, 2020 537,373 $ 46.07 Exercised (25,306) 43.76 Stock options outstanding as of December 31, 2021 (1) 512,067 46.18 __________ (1) There were no options granted, canceled, exercised or forfeited during the years ended December 31, 2023 and 2022. The Company had 512,067 options exercisable as of December 31, 2023, 2022 and 2021, respectively, with a weighted average exercise price of $46.18 at each date. As of December 31, 2023 and 2022, these options had a weighted average remaining life of 2.0 years and 3.0 years, respectively, and all had exercise prices higher than the market price of our common stock. No options were exercised during the years ended December 31, 2023 and 2022 , respectively . Cash received or receivable from options exercised was $1.1 million for the year ended December 31, 2021. The total intrinsic value of options exercised during the year ended December 31, 2021 was $0.1 million. The total intrinsic value of options outstanding as of December 31, 2021 was $0.6 million. The Company generally does not permit the net cash settlement of exercised stock options, but does permit net share settlement so long as the shares received are held for at least a year. The Company has a practice of issuing new shares to satisfy stock option exercises. - Time-Based Restricted Stock Shares of time-based restricted stock vest ratably on an annual basis generally over four years. Beginning in 2019, shares of time-based restricted stock granted to non-employee directors vest on the first anniversary of the grant date. The value of grants of time-based restricted stock is based on the market value of Common Stock as of the date of grant and is amortized to expense over the respective vesting period or the service period, if shorter, for employees who are or will become eligible under the Company’s retirement plan. The following table sets forth time-based restricted stock activity: Number of Shares Weighted Average Grant Date Fair Value Restricted shares outstanding as of December 31, 2020 209,190 $ 45.34 Awarded and issued (1) 103,120 39.99 Vested (2) (89,264) 45.90 Forfeited (3,327) 43.13 Restricted shares outstanding as of December 31, 2021 219,719 42.63 Awarded and issued (1) 99,975 43.58 Vested (2) (101,082) 42.80 Forfeited (779) 42.37 Restricted shares outstanding as of December 31, 2022 217,833 43.00 Awarded and issued (1) 155,717 26.42 Vested (2) (95,423) 43.57 Forfeited (1,819) 34.11 Restricted shares outstanding as of December 31, 2023 276,308 $ 33.51 __________ (1) The weighted average fair value at grant date of time-based restricted stock issued during the years ended December 31, 2023, 2022 and 2021 was $4.1 million, $4.4 million and $4.1 million, respectively. (2) The vesting date fair value of time-based restricted stock that vested during the years ended December 31, 2023, 2022 and 2021 was $2.5 million, $4.4 million and $3.6 million, respectively. Vested shares include those shares surrendered by employees to satisfy tax withholding obligations in connection with such vesting. - Total Return-Based Restricted Stock Shares of total return-based restricted stock vest to the extent the Company’s absolute total returns for certain pre-determined three-year periods exceed predetermined goals. The amount subject to vesting ranges from zero to 150%. For total return-based restricted stock issued prior to 2022, notwithstanding the Company’s absolute total return, if the Company’s total return exceeds 100% of the average peer group total return index, 100% of total return-based restricted stock issued will vest at the end of the applicable period. For total return-based restricted stock issued since 2022, notwithstanding the Company’s absolute total return, if the Company’s total return is in the 50th percentile or greater as compared to all of the companies included in the FTSE NAREIT Equity Office Index, 100% 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 2023, 2022 and 2021 was determined to be $27.06, $41.94 and $36.41, 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: 2023 2022 2021 Risk free interest rate (1) 4.4 % 1.6 % 0.3 % Common stock dividend yield (2) 6.9 % 4.5 % 4.8 % Expected volatility (3) 27.2 % 25.8 % 26.8 % __________ (1) Represents the interest rate as of the grant date on US treasury bonds having the same life as the estimated life of the total return-based restricted stock grants. (2) The dividend yield is calculated utilizing the then current regular dividend rate for a one-year period and the average per share price of Common Stock during the three-month period preceding the date of grant. (3) Based on the historical volatility of Common Stock over a period relevant to the related total return-based restricted stock grant. The following table sets forth total return-based restricted stock activity: Number of Shares Weighted Average Grant Date Fair Value Restricted shares outstanding as of December 31, 2020 225,184 $ 39.53 Awarded and issued (1) 81,464 36.41 Vested (2) (55,452) 43.01 Forfeited (3) (21,904) 42.33 Restricted shares outstanding as of December 31, 2021 229,292 38.00 Awarded and issued (1) 81,832 41.94 Vested (2) (62,985) 45.90 Forfeited (3) (20,995) 45.90 Restricted shares outstanding as of December 31, 2022 227,144 38.93 Awarded and issued (1) 126,736 27.06 Vested (2) (65,140) 44.88 Forfeited (3) (2,148) 35.83 Restricted shares outstanding as of December 31, 2023 286,592 $ 34.03 __________ (1) The fair value at grant date of total return-based restricted stock issued during the years ended December 31, 2023, 2022 and 2021 was $3.4 million, $3.4 million and $2.9 million, respectively, at target. (2) The vesting date fair value of total return-based restricted stock that vested during the years ended December 31, 2023, 2022 and 2021 was $1.7 million, $2.7 million and $2.2 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 2022 and 2021 amounts include 20,995 and 18,484 shares, respectively, that were forfeited at the end of the applicable measurement period because the applicable total return did not meet targeted levels. No shares were forfeited in 2023. 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, 2023, 2022 and 2021, 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 $2.3 million and $2.6 million as of December 31, 2023 and 2022, 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, 2023 2022 2021 Beginning deferred compensation liability $ 2,564 $ 2,866 $ 2,573 Mark-to-market adjustment to deferred compensation (in general and administrative expenses) 243 (302) 293 Distributions from deferred compensation plans (513) — — Total deferred compensation liability $ 2,294 $ 2,564 $ 2,866 Employee Stock Purchase Plan The Company has an Employee Stock Purchase Plan (“ESPP”) pursuant to which employees may contribute up to 25% of their cash compensation for the purchase of Common Stock. At the end of each quarter, each participant’s account balance, which includes accumulated dividends, is applied to acquire shares of Common Stock at a cost that is calculated at 85% of the average closing price on the NYSE on the five

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 $1.42, $1.60 and $1.61 per share in 2023, 2022 and 2021, 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 $5.6 billion and $3.5 billion, respectively, as of December 31, 2023 and $5.6 billion and $3.5 billion, respectively, as of December 31, 2022. The tax basis of the Operating Partnership’s assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $5.4 billion and $3.5 billion, respectively, as of December 31, 2023 and $5.4 billion and $3.5 billion, respectively, as of December 31, 2022. During the years ended December 31, 2023, 2022 and 2021, 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. The Company had no net deferred tax asset or liability as of December 31, 2023 or December 31, 2022.

Segment Information	Segment Information Our principal business is the operation, acquisition and development of rental office properties. We evaluate our business by geographic location. The operating results by geographic grouping are regularly reviewed by our chief operating decision maker for assessing performance and other purposes. There are no material inter-segment transactions. Our accounting policies of the segments are the same as those used in our Consolidated Financial Statements. All operations are within the United States. The following tables summarize rental and other revenues, net operating income and total assets for our office properties. Net operating income is the primary industry property-level performance metric used by our chief operating decision maker and is defined as rental and other revenues less rental property and other expenses.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Our $750.0 million unsecured revolving credit facility was modified on January 25, 2024 and is now scheduled to mature in January 2028 (but can be extended for two additional six-month periods at our option assuming no defaults have occurred). The interest rate on our newly modified revolving credit facility remains SOFR plus a related spread adjustment of 10 basis points and a borrowing spread of 85 basis points, based on current credit ratings and the annual facility fee remains 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. Subject to written consent of the lenders, we may elect to amend the newly modified revolving credit facility no later than May 15, 2024 to provide that the interest rate may be adjusted upward or downward by up to 2.5 basis points subject to satisfaction of certain to-be-determined sustainability goals with respect to the ongoing reduction of greenhouse gas emissions. The financial and other covenants under our newly modified facility are substantially similar to our previous credit facility. We expect to incur $7.9 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 expect to record $0.2 million of loss on debt extinguishment. As of January 26, 2024, there was $36.0 million outstanding under our revolving credit facility and $0.9 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 as of January 26, 2024 was $713.1 million. On January 31, 2024, the Company declared a cash dividend of $0.50 per share of Common Stock, which is payable on March 12, 2024 to stockholders of record as of February 20, 2024.

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. In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. As of December 31, 2023, we are involved with six entities we determined to be variable interest entities, one of which we are the primary beneficiary and is consolidated and five of which we are not the primary beneficiary and are not consolidated. We also own three properties through a joint venture investment that were deconsolidated effective January 1, 2023 (see Note 4). 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	Insurance We are primarily self-insured for health care claims for participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities. As of December 31, 2023, 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 three Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy and capitalize only those costs associated with the portion under construction. We record liabilities for the performance of asset retirement activities when the obligation to perform such activities is probable even when uncertainty exists about the timing and/or method of settlement. Upon the acquisition of real estate assets accounted for as asset acquisitions, we assess the fair value of acquired tangible assets such as land, buildings and tenant improvements, intangible assets and liabilities such as above and below market leases, acquired in-place leases and other identifiable intangible assets and assumed liabilities. We allocate fair value on a relative basis based on estimated cash flow projections that utilize discount and/or capitalization rates as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. The above and below market rate portions of leases acquired in connection with property acquisitions are recorded in deferred leasing costs and in accounts payable, accrued expenses and other liabilities, respectively, at fair value and amortized into rental revenue over the remaining term of the respective leases as described below. Fair value is calculated as the present value of the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) our estimate of fair market lease rates for each corresponding in-place lease, using a discount rate that reflects the risks associated with the leases acquired and measured over a period equal to the remaining initial term of the lease for above-market leases and the remaining initial term plus the term of any renewal option that the customer would be economically compelled to exercise for below-market leases. In-place leases acquired are recorded at fair value in deferred leasing costs and 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. Assumed debt, if any, is recorded at fair value based on the present value of the expected future payments.
Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates	Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates With respect to assets classified as held for use, we perform an impairment analysis if our evaluation of events or changes in circumstances indicate that the carrying value may not be recoverable, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset’s carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete. If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and 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 subject to future events that may alter our assumptions, we may be required to recognize future impairment losses on our investments in unconsolidated affiliates.
Sales of Real Estate	Sales of Real Estate For sales of real estate where we have determined an enforceable contract exists and collection of the consideration to which we are entitled in exchange for transferring the real estate is probable, 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 a separate performance obligation and the allocable sales price is recognized when the separate performance obligation is satisfied.
Leases	Leases We generally lease our office properties to lessees in exchange for fixed monthly payments that cover rent, property taxes, insurance and certain cost recoveries, primarily common area maintenance (“CAM”). Our office properties that are under lease are primarily located in Atlanta, Charlotte, Dallas, Nashville, Orlando, Raleigh, Richmond and Tampa and are leased to a wide variety of lessees across many industries. Our leases are operating leases and mostly range from three line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Some of our leases are subject to annual changes in the Consumer Price Index (“CPI”). Although increases in the CPI are not estimated as part of our measurement of straight-line rental revenue, to the extent that actual CPI is greater or less than the CPI at lease commencement, the amount of rent recognized in a given year is affected accordingly. Some of our leases have termination and/or extension options. Termination options allow the customer to terminate the lease prior to the end of the lease term under certain circumstances. Termination options generally become effective halfway or further into the original lease term and require advance notification from the customer and payment of a termination fee that reimburses us for a portion of the remaining rent under the original lease term and the undepreciated lease inception costs such as commissions, tenant improvements and lease incentives. Termination fee income is recognized on a straight-line basis from the date of the executed termination agreement through lease expiration when the amount of the fee is determinable and collectability of the fee is reasonably assured. Our extension options generally require a re-negotiation with the customer at market rates. Initial direct costs, primarily commissions, related to the leasing of our office properties are included in deferred leasing costs and are stated at amortized cost. Such expenditures are part of the investment necessary to execute leases and are, therefore, classified as investment activities in the statement of cash flows. All leasing commissions paid to third parties and our in-house personnel for new leases or lease renewals are capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases. All other costs to negotiate or arrange a lease are expensed as incurred. Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign a lease, are capitalized in deferred leasing costs and amortized on a straight-line basis over the respective lease terms as a reduction of rental revenues. Lease related receivables, which include accounts receivable and accrued straight-line rents receivable, are reduced for credit losses. Such amounts are recognized as a reduction to rental and other revenues. We regularly evaluate the collectability of our lease related receivables. Our evaluation of collectability primarily consists of reviewing the credit quality of our customer, historical trends of the customer and changes in customer payment terms. We do not maintain a general reserve to estimate amounts that may not be collectible. If our assumptions regarding the collectability of lease related receivables prove incorrect, we could experience credit losses in excess of what was recognized in rental and other revenues.
Discontinued Operations	Discontinued Operations Properties that are sold or classified as held for sale are classified as discontinued operations provided that the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results. Interest expense is included in discontinued operations if a related loan securing the sold property is to be paid off or assumed by the buyer in connection with the sale.
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates We account for our joint venture investments using the equity method of accounting when our interests represent a general partnership interest but substantive participating rights or substantive kick out rights have been granted to the limited partners or when our interests do not represent a general partnership interest and we do not control the major operating and financial policies of the investment. These investments are initially recorded at cost as investments in unconsolidated affiliates and are subsequently adjusted for our share of earnings and cash contributions and distributions. To the extent our cost basis at formation of the joint venture is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related assets and included in our share of equity in earnings of unconsolidated affiliates.
Cash Equivalents	Cash Equivalents We consider highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
Restricted Cash	Restricted Cash Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as construction-related escrows, property disposition proceeds set aside and designated or intended to fund future tax-deferred exchanges of qualifying real estate investments and escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements.
Redeemable Common Units and Preferred Units	Redeemable Common Units and Preferred Units Limited partners holding Common Units other than the Company (“Redeemable Common Units”) have the right to put any and all of the Common Units to the Operating Partnership and the Company has the right to put any and all of the Preferred Units to the Operating Partnership in exchange for their liquidation preference plus accrued and unpaid distributions in the event of a corresponding redemption by the Company of the underlying Preferred Stock. Consequently, these Redeemable Common Units and Preferred Units are classified outside of permanent partners’ capital in the Operating Partnership’s accompanying balance sheets. The recorded value of the Redeemable Common Units is based on fair value at the balance sheet date as measured by the closing price of Common Stock on that date multiplied by the total number of Redeemable Common Units outstanding. The recorded value of the Preferred Units is based on their redemption value.
Income Tax	Income Taxes The Company has elected and expects to continue to qualify as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”). A corporate REIT is a legal entity that holds real estate assets and, through the payment of dividends to stockholders, is generally permitted to reduce or avoid the payment of federal and state income taxes at the corporate level. To maintain qualification as a REIT, the Company is required to pay dividends to its stockholders equal to at least 90.0% of its annual REIT taxable income, excluding net capital gains. The partnership agreement requires the Operating Partnership to pay economically equivalent distributions on outstanding Common Units at the same time that the Company pays dividends on its outstanding Common Stock. Other than income taxes related to its taxable REIT subsidiary, the Operating Partnership does not reflect any federal income taxes in its financial statements since, as a partnership, the taxable effects of its operations are attributed to its partners. The Operating Partnership does record state income tax for states that tax partnership income directly. We conduct certain business activities through a taxable REIT subsidiary, as permitted under the Code. The taxable REIT subsidiary is subject to federal, state and local income taxes on its taxable income. We record provisions for income taxes based on its income recognized for financial statement purposes, including the effects of differences between such income and the amount recognized for tax purposes.
Concentration of Credit Risk	Concentration of Credit Risk As of December 31, 2023, our consolidated properties were leased to approximately 1,500 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Atlanta, Charlotte, Nashville, Raleigh and Tampa . Our customers engage in a wide variety of businesses. No single customer generated more than 4% of our consolidated revenues during 2023. We maintain our cash and cash equivalents and our restricted cash at financial or other intermediary institutions. The combined account balances at each institution may exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. Additionally, from time to time in connection with tax-deferred 1031 transactions, our restricted cash balances may be commingled with other funds being held by any such intermediary institution, which would subject our balance to the credit risk of the institution.
Derivative Financial Instruments	Derivative Financial Instruments We borrow funds at a combination of fixed and variable rates. Borrowings under our revolving credit facility and bank term loans bear interest at variable rates. Our long-term debt, which consists of secured and unsecured long-term financings, typically bears interest at fixed rates. Our interest rate risk management objectives are to generally limit 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 Interest rate swaps involve the receipt of variable rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income/(loss) and are subsequently reclassified into interest expense as interest payments are made on our debt. We account for terminated derivative instruments by recognizing the related accumulated other comprehensive income/(loss) balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated other comprehensive income/(loss) into interest expense 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 for 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 for 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 provides temporary optional expedients and exceptions to ease the financial reporting burdens related to the market transition from LIBOR and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). These optional expedients and exceptions provide guidance on contract modifications and hedge accounting. We have completed the transition to SOFR rates for our applicable outstanding debt instruments with no material impact to our Consolidated Financial Statements. The FASB issued an ASU that will require enhanced segment disclosures, primarily regarding significant segment expenses. The ASU is required to be adopted in our 2024 Annual Report and applied retrospectively to all prior periods presented in the financial statements. We do not expect such adoption to have a material effect on our Notes to Consolidated Financial Statements.
