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, 2024, we owned or had an interest in 27.8 million rentable square feet of in-service properties, 1.6 million rentable square feet of office properties under development and development land with approximately 4.9 million rentable square feet of potential office build out.

The Company is the sole general partner of the Operating Partnership. As of December 31, 2024, the Company owned all of the Preferred Units and 107.2 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 2024, the Company redeemed 5,385 Common Units for a like number of shares of Common Stock.

Basis of Presentation

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

The Company’s Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership’s Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. We consolidate joint venture investments, such as interests in partnerships and limited liability companies, when we control the major operating and financial policies of the investment through majority ownership, in our capacity as a general partner or managing member or through some other contractual right. 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, 2024, 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.

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. To limit our exposure to significant claims, we have stop-loss coverage on a per claim and annual aggregate basis. We use all relevant information to determine our liabilities for claims, including actuarial estimates of claim liabilities. When determining our liabilities, we include claims for
incurred losses, even if they are unreported. As of December 31, 2024, 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 to seven years for furniture, fixtures and equipment. Tenant improvements are amortized using the straight-line method over the initial fixed terms of the respective leases, which generally range from three to 10 years. Depreciation expense for real estate assets was $256.0 million, $253.2 million and $240.3 million for the years ended December 31, 2024, 2023 and 2022, respectively.

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 to 10 years. Payments from customers for CAM are considered nonlease components that are separated from lease components and are generally accounted for in accordance with the revenue recognition standard. However, we qualified for and elected the practical expedient related to combining the components because the lease component is classified as an operating lease and the timing and pattern of transfer of CAM income, which is not the predominant component, is the same as the lease component. As such, consideration for CAM is accounted for as part of the overall consideration in the lease. Payments from customers for property taxes and insurance are considered noncomponents of the lease and therefore no consideration is allocated to them because they do not transfer a good or service to the customer. Fixed contractual payments from our leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements.
Some of our leases are subject to annual changes in the Consumer Price Index (“CPI”). Although increases in the CPI are not estimated as part of our measurement of straight-line rental revenue, to the extent that actual CPI is greater or less than the CPI at lease commencement, the amount of 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 when the amount recorded is determined, in management’s judgement, to not be probable of collection. 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, 2024, 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 2024.

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 or three month intervals, subject to settlements under these interest rate hedge contracts.

Interest rate swaps involve the receipt of variable rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Changes in the fair value of
derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income/(loss) and are subsequently reclassified into interest expense as interest payments are made on our debt.

We account for terminated derivative instruments by recognizing the related accumulated other comprehensive income/(loss) balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated other comprehensive income/(loss) into 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 requires enhanced segment disclosures, primarily regarding significant segment expenses. We have adopted this ASU and applied the new requirements retrospectively to all prior periods presented in the financial statements. Accordingly, our segment disclosures now include rental property and other expenses for each of our reportable segments. See Note 15.

The FASB issued an ASU that requires disaggregated disclosure of income statement expenses. Certain expense captions will be disaggregated into specified categories in disclosures within the Notes to Consolidated Financial Statements. The ASU is required to be adopted in our 2027 Annual Report. We do not expect this adoption to have a material effect on our Consolidated Financial Statements.

Information as Lessee

We have office assets encompassing 1.2 million rentable square feet subject to operating ground leases in Nashville, Orlando, Raleigh and Tampa with a weighted average remaining term of 50 years. Rental payments on these leases are adjusted periodically based on either the CPI or on a pre-determined schedule. The monthly payments on a pre-determined schedule are recognized on a straight-line basis over the terms of the respective leases. Changes in the CPI are not estimated as part of our measurement of straight-line rental expense. We recognized $2.6 million of ground lease expense during each of the years ended December 31, 2024, 2023, and 2022, and we paid $2.5 million, $2.4 million and $2.4 million in cash during 2024, 2023 and 2022, respectively.

Acquisitions

During 2024, we acquired fee simple title to the land underneath our Century Center assets in Atlanta for a purchase price, including capitalized acquisition costs, of $50.8 million. We previously held most of our buildings in Century Center, a 12-building office park encompassing 1.7 million square feet and 13 acres of developable land, pursuant to a long-term ground lease with a third party who owned fee simple title to the land.

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.

Dispositions

During 2024, we sold a total of 10 buildings in Raleigh and land in Greensboro for an aggregate sales price of $105.3 million and recorded aggregate gains on disposition of property of $46.8 million. The land sale completed our exit from the Greensboro market.

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.

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.

Impairments

During 2024, we recorded an impairment charge of $24.6 million to lower the carrying amount of EQT Plaza, a 616,000 square foot non-core building in CBD Pittsburgh, to its estimated fair value.

During 2022, we recorded the following impairment charges:

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; and
During the second quarter of 2022, we recorded an impairment charge of $35.0 million to lower the carrying amount of EQT Plaza to its estimated fair value.

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 $21.3 million and $18.9 million as of December 31, 2024 and 2023, respectively.

- 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.

- 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, 2024, we have funded $76.2 million of our share of the equity for the Granite Park Six joint venture and $94.0 million of our share of the equity for the 23Springs joint venture.

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 were 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.

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 interest rate hedge contracts that effectively cap the underlying SOFR rate at 3.5%. The initial contract capped the rate with respect to $95.2 million of any outstanding amounts and expired in July 2024. The new contract caps the rate with respect to $38.8 million of any outstanding amounts and expires in July 2025. During 2024, we and Granite each contributed $35.5
million to the Granite Park Six joint venture to pay down the outstanding $70.9 million balance of the construction loan. This reconsideration event did not change our initial conclusion that the Granite Park Six joint venture is a variable interest entity of which we are not the primary beneficiary. As such, the entity remains unconsolidated. As of December 31, 2024, $1.9 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 interest rate hedge contracts that effectively cap the underlying SOFR rate at 3.5%. The initial contract capped the rate with respect to $83.0 million of any outstanding amounts and expired in April 2024. The new contract caps the rate with respect to $134.0 million of any outstanding amounts and expires in April 2025. As of December 31, 2024, $94.6 million was drawn on this loan.

As of December 31, 2024, our risk of loss with respect to these arrangements was limited to the carrying value of each investment balance. Our investment balances were $76.8 million and $101.5 million as of December 31, 2024 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. 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%. 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.

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, were 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.

During 2024, the McKinney & Olive joint venture paid off at maturity the remaining $134.3 million balance on the secured mortgage loan. In connection with this loan payoff, we and Granite each contributed $62.1 million to the joint venture.

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.

These reconsideration events did not change our initial conclusion that the McKinney & Olive joint venture is a variable interest entity of which we are not the primary beneficiary. As such, the entity remains unconsolidated.

As of December 31, 2024, our risk of loss with respect to this arrangement was limited to the carrying value of our investment balance of $182.1 million. 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, $14.2 million of which was funded as of December 31, 2024. 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, 2024, $21.4 million was 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 as both a debt and 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 were 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, 2024, our risk of loss with respect to this arrangement was $35.5 million, which consists of the $14.1 million carrying value of our investment balance plus the $21.4 million outstanding balance of the loan we have provided to the joint venture. 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 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 also committed to provide a $52.8 million interest-only secured construction loan to the 2827 Peachtree joint venture that was originally scheduled to mature in December 2024 with an option to extend for one year. During 2024, the joint venture exercised the option to extend the loan for one year. The loan bears interest at SOFR plus 310 basis points. As of December 31, 2024, $48.2 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 as both a debt and 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 were 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, 2024, our risk of loss with respect to this arrangement was $60.7 million, which consists of the $12.5 million carrying value of our investment balance plus the $48.2 million outstanding balance of the loan we have provided to the joint venture. 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, 2024, 2023 and 2022, we recognized $0.9 million, $1.0 million and $0.6 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 2023.

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 and Bromley as equity holders. 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 were 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. As such, the Midtown West joint venture is consolidated and all intercompany transactions and accounts are eliminated.

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. This reconsideration event 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:

Our $750.0 million unsecured revolving credit facility was modified during the first quarter of 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 revolving credit facility is 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 is 20 basis points. The interest rate and facility fee are based on the higher of the publicly announced ratings from Moody’s Investors Service or Standard & Poor’s Ratings Services. We incurred $7.7 million of debt issuance costs during the first quarter of 2024, which will be amortized along with certain existing unamortized debt issuance costs over the remaining term of our new revolving credit facility and recorded $0.2 million of loss on debt extinguishment. During the second quarter of 2024, we modified the revolving credit facility to provide that the interest rate may be adjusted upward or downward by 2.5 basis points depending upon whether or not we achieve certain pre-determined sustainability goals with respect to the ongoing reduction of greenhouse gas emissions. There was $104.0 million and $119.0 million outstanding under our revolving credit facility as of December 31, 2024 and January 31, 2025, respectively. As of both December 31, 2024 and January 31, 2025, we had $0.1 million of outstanding letters of credit, which reduce the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility as of December 31, 2024 and January 31, 2025 was $645.9 million and $630.9 million, respectively.

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%. 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.

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 had $2,141.8 million carrying amount of various notes outstanding as of December 31, 2024, 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 11, 2025 (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 $8.5 million, $9.0 million and $4.0 million for the years ended December 31, 2024, 2023 and 2022, respectively.

Lease and Contractual Commitments

We had $232.6 million of lease and contractual commitments as of December 31, 2024. 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 $59.7 million was recorded on our Consolidated Balance Sheets as of December 31, 2024.

Contingent Consideration

We had $0.8 million of contingent consideration related to a parcel of acquired development land as of both December 31, 2024 and 2023. The contingent consideration is payable in cash to a third party if and to the extent future development milestones as outlined in the purchase agreement 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 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.

As of December 31, 2024, our noncontrolling interest in consolidated affiliates relates 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.

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:

The Level 3 impaired real estate assets measured at a fair value of $26.7 million in the fourth quarter of 2024 included EQT Plaza, a non-core office building in CBD Pittsburgh. This impairment resulted from a change in our assumptions about the use of the asset. We estimated the fair value using a discounted cash flow analysis. We also used information from a broker’s opinion of value, which incorporates an income approach, as observable inputs were not available. Key assumptions used in the impairment calculation were an estimated discount rate ranging from 16.7% to 19.9% and an estimated terminal capitalization rate of 9.5%.

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. During 2024, the Company issued 1.6 million shares of Common Stock under its equity distribution agreements at an average gross sales price of $32.71 per share and received net proceeds, after sales commissions, of $51.3 million. There were no shares issued under these agreements in 2023. As of December 31, 2024, the Company had 92.4 million remaining shares of Common Stock authorized to be issued under its charter.

The Company’s tax returns have not been examined by the IRS and, therefore, the taxability of dividends is subject to change.
Warrants

As of both December 31, 2024 and 2023, 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 for each of the years ended December 31, 2024, 2023 and 2022.

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 20% 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:

Possible future issuance under equity incentive plans2,242,360 2,537,816 
2,709,651 3,064,883 

Of the possible future issuance under the Company’s long-term equity incentive plans as of December 31, 2024, no more than an additional 0.2 million shares can be in the form of restricted stock.

During the years ended December 31, 2024, 2023 and 2022, we recognized share-based compensation expense of $8.0 million, $7.0 million and $7.6 million, respectively. Because REITs generally do not pay income taxes, we do not realize tax benefits on share-based payments. As of December 31, 2024, there was $4.1 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.

(1)There were no options granted, canceled, exercised, expired or forfeited during the years ended December 31, 2023 and 2022.
(2)The Company had 452,291 options exercisable as of December 31, 2024 with a weighted average exercise price of $47.30 and a weighted average remaining life of 1.3 years. As of December 31, 2024, all of these options had exercise prices higher than the market price of our common stock.

No options were exercised during the years ended December 31, 2024, 2023 and 2022. 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 granted to employees 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.

(2)The vesting date fair value of time-based restricted stock that vested during the years ended December 31, 2024, 2023 and 2022 was $2.8 million, $2.5 million and $4.4 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 2024, 2023 and 2022 was determined to be $25.22, $27.06 and $41.94, 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:

(2)The vesting date fair value of total return-based restricted stock that vested during the years ended December 31, 2024, 2023 and 2022 was $1.9 million, $1.7 million and $2.7 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 amount includes 20,995 shares that were forfeited at the end of the applicable measurement period because the applicable total return did not meet targeted levels. No such 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 each of the years ended December 31, 2024, 2023 and 2022, we contributed $1.4 million 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 who 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 as of both December 31, 2024 and 2023, 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:

Employee Stock Purchase Plan

The Company has an Employee Stock Purchase Plan (“ESPP”) pursuant to which employees may contribute up to 25% of their cash compensation for the purchase of Common Stock. At the end of each quarter, each participant’s account balance, which includes accumulated dividends, is applied to acquire shares of Common Stock at a cost that is calculated at 85% of the average closing price on the NYSE on the five consecutive days preceding the last day of the quarter. In the years ended December 31, 2024, 2023 and 2022, the Company issued 51,711, 77,086 and 46,656 shares, respectively, of Common Stock under the ESPP. The 15% discount on newly issued shares, which is taxable income to the participants and is recorded by us as additional compensation expense, aggregated $0.2 million, $0.3 million and $0.2 million in the years ended December 31, 2024, 2023 and 2022, respectively. Generally, shares purchased under the ESPP must be held for at least one year. The Company satisfies its ESPP obligations by issuing additional shares of Common Stock.

Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes
Our Consolidated Financial Statements include the operations of the Company’s taxable REIT subsidiary, which is not entitled to the dividends paid deduction and is subject to federal, state and local income taxes on its taxable income.

The minimum dividend per share of Common Stock required for the Company to maintain its REIT status was $1.42, $1.42 and $1.60 per share in 2024, 2023 and 2022, 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 $5.7 billion and $3.6 billion, respectively, as of December 31, 2024 and $5.6 billion and $3.5 billion, respectively, as of December 31, 2023. The tax basis of the Operating Partnership’s assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $5.6 billion and $3.6 billion, respectively, as of December 31, 2024 and $5.4 billion and $3.5 billion, respectively, as of December 31, 2023.

During the years ended December 31, 2024, 2023 and 2022, 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, 2024 or December 31, 2023.
For each of the years ended December 31, 2024 and 2023, there were no unrecognized tax benefits. The Company is subject to federal, state and local income tax examinations by taxing authorities for 2021 through 2024. The Company does not expect that the total amount of unrecognized benefits will materially change within the next year.

Segment Reporting [Abstract]  
Segment Information Segment Information
Our principal business is the operation, acquisition and development of rental office properties. We evaluate our business by geographic location, which is why our primary geographic locations are included as reportable segments below. The operating results by geographic grouping are regularly reviewed by our chief operating decision maker for assessing performance and other purposes. Our chief executive officer is our chief operating decision maker. 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, rental property and other expenses, net operating income and total assets for each of our reportable segments. 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. Our chief operating decision maker uses net operating income to help assess segment performance and decide how to allocate resources accordingly.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
We face risks associated with security breaches through cyber attacks, cyber intrusions or otherwise, and other significant disruptions of information technology networks and related systems. See also “Item 1A. Risk Factors – Risks Related to our Operations – We face risks associated with security breaches through cyber attacks, cyber intrusions, ransomware or otherwise, as well as other significant disruptions of our information technology (“IT”) networks and related systems.” We have never experienced any cybersecurity incidents that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations or financial condition. With the assistance of a third party technology consulting firm, we have adopted and implemented an approach to identify and mitigate cybersecurity risks. For example, we have adopted and implemented, or are in the process of adopting and implementing, many of the voluntary practices recommended under the National Institute of Standards and Technology cybersecurity framework 2.0, which we believe is a best practice for U.S.-based real estate companies.

Management’s information technology steering committee, which is led by the chief information officer and includes all of our executive officers, is responsible for assessing and managing material risks from cybersecurity threats from our own information technology networks and systems we use that are owned by third party service providers. Ryan Hunt has served as our chief information officer since June 2021. Mr. Hunt joined us in 1997 and quickly transitioned his focus to technology. He began his technology career on the IT help desk, served in various other roles within the technology department and most recently served in the role of senior director of application development. Mr. Hunt earned his Bachelor of Science degree in Management Information Systems from North Carolina State University.

Under the direction of our chief information officer with oversight from management’s steering committee, the Company has implemented a cybersecurity incident response plan that sets forth a process for detecting and responding to cybersecurity incidents, determining their scope and risk, developing an appropriate response to mitigate and remediate the incident, communicating effectively to all stakeholders and participants and reducing the likelihood of similar future incidents. In the event of a real or perceived cybersecurity incident, the chief information officer would, as soon as practicable, inform management’s steering committee, the members of which would then collaborate with the chief information officer to manage material risks.

In the event of a real or perceived cybersecurity incident, the chief information officer would, as soon as practicable, inform management’s steering committee, the members of which would then collaborate with the chief information officer to manage material risks.
As part of our overall enterprise risk management processes and to better evaluate our cybersecurity risks, we have conducted a business impact analysis by leveraging our annual company-wide enterprise risk management assessment to understand the relationship between our critical business operations and our information technology systems. We partner with a
third party service provider to assist us on a real-time basis with detecting advanced threats, streamline and collaborate on investigations and recommend actions to further strengthen our systems and, if and when necessary, respond to incidents. In addition, we regularly engage independent third parties to test our cybersecurity processes and systems through consulting, independent audits and penetration testing. We also have a cyber risk insurance policy designed to help us mitigate risk exposure by offsetting costs involved with recovery and remediation after a cybersecurity breach or similar event.

We regularly conduct cybersecurity training to ensure all employees are aware of cybersecurity risks and to enable them to take steps to mitigate such risks. For example, all employees are required to successfully complete a cybersecurity risk module and assessment on a quarterly basis. As part of this program, we also take reasonable steps to ensure any employee who may come into possession of confidential financial or health information has received appropriate cybersecurity awareness training and, if applicable, payment card industry (PCI) training.

The audit committee of the Company’s Board of Directors is responsible for overseeing management’s information technology steering committee as well as management’s risk assessment and risk management processes designed to monitor and control cybersecurity threats. Management’s steering committee, led by the Company’s chief information officer, regularly briefs the audit committee on cybersecurity matters. These briefings generally occur on a quarterly basis. In the event we experience a cybersecurity incident that could materially affect us, including our business strategy, results of operations or financial condition, the Company’s chief information officer and other members of management’s steering committee (which include executive officers who are also part of our disclosure committee) would review the incident with the audit committee to consider whether and to what extent disclosure is required under Item 1.05 of Form 8-K.

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, 2024, 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.

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. To limit our exposure to significant claims, we have stop-loss coverage on a per claim and annual aggregate basis. We use all relevant information to determine our liabilities for claims, including actuarial estimates of claim liabilities. When determining our liabilities, we include claims for
incurred losses, even if they are unreported. As of December 31, 2024, a reserve of $0.5 million was recorded to cover estimated reported and unreported claims.
Real Estate and Related Assets
Real Estate and Related Assets

Real estate and related assets are recorded at cost and stated at cost less accumulated depreciation. Renovations, replacements and other expenditures that improve or extend the life of assets are capitalized and depreciated over their estimated useful lives. Expenditures for ordinary maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful life of 40 years for buildings and depreciable land infrastructure costs, 15 years for building improvements and five to seven years for furniture, fixtures and equipment. Tenant improvements are amortized using the straight-line method over the initial fixed terms of the respective leases, which generally range from three to 10 years. Depreciation expense for real estate assets was $256.0 million, $253.2 million and $240.3 million for the years ended December 31, 2024, 2023 and 2022, respectively.

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
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 to 10 years. Payments from customers for CAM are considered nonlease components that are separated from lease components and are generally accounted for in accordance with the revenue recognition standard. However, we qualified for and elected the practical expedient related to combining the components because the lease component is classified as an operating lease and the timing and pattern of transfer of CAM income, which is not the predominant component, is the same as the lease component. As such, consideration for CAM is accounted for as part of the overall consideration in the lease. Payments from customers for property taxes and insurance are considered noncomponents of the lease and therefore no consideration is allocated to them because they do not transfer a good or service to the customer. Fixed contractual payments from our leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements.
Some of our leases are subject to annual changes in the Consumer Price Index (“CPI”). Although increases in the CPI are not estimated as part of our measurement of straight-line rental revenue, to the extent that actual CPI is greater or less than the CPI at lease commencement, the amount of 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 when the amount recorded is determined, in management’s judgement, to not be probable of collection. 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, 2024, 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 2024.

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 or three month intervals, subject to settlements under these interest rate hedge contracts.

Interest rate swaps involve the receipt of variable rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Changes in the fair value of
derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income/(loss) and are subsequently reclassified into interest expense as interest payments are made on our debt.

We account for terminated derivative instruments by recognizing the related accumulated other comprehensive income/(loss) balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated other comprehensive income/(loss) into 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 requires enhanced segment disclosures, primarily regarding significant segment expenses. We have adopted this ASU and applied the new requirements retrospectively to all prior periods presented in the financial statements. Accordingly, our segment disclosures now include rental property and other expenses for each of our reportable segments. See Note 15.

The FASB issued an ASU that requires disaggregated disclosure of income statement expenses. Certain expense captions will be disaggregated into specified categories in disclosures within the Notes to Consolidated Financial Statements. The ASU is required to be adopted in our 2027 Annual Report. We do not expect this adoption to have a material effect on our Consolidated Financial Statements.
