Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Significant Accounting Policies	Description of Business and Significant Accounting Policies Description of Business Highwoods Properties, Inc. (the “Company”) is a fully integrated real estate investment trust (“REIT”) that provides leasing, management, development, construction and other customer-related services for its properties and for third parties. The Company conducts its activities through Highwoods Realty Limited Partnership (the “Operating Partnership”). At December 31, 2015 , we owned or had an interest in 32.5 million rentable square feet of in-service properties, 1.5 million rentable square feet of properties under development and approximately 500 acres of development land. The Company is the sole general partner of the Operating Partnership. At December 31, 2015 , the Company owned all of the Preferred Units and 95.7 million , or 97.1% , of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.9 million Common Units. In the event the Company issues shares of Common Stock, the net proceeds of the issuance are contributed to the Operating Partnership in exchange for additional Common Units. Generally, the Operating Partnership is obligated to redeem each Common Unit at the request of the holder thereof for cash equal to the value of one share of Common Stock based on the average of the market price for the 10 trading days immediately preceding the notice date of such redemption, provided that the Company, at its option, may elect to acquire any such Common Units presented for redemption for cash or one share of Common Stock. The Common Units owned by the Company are not redeemable. During 2015 , the Company redeemed 37,203 Common Units for a like number of shares of Common Stock. As a result of this activity, in conjunction with the proceeds from issuances of Common Stock (see Note 12), the percentage of Common Units owned by the Company increased from 96.9% at December 31, 2014 to 97.1% at December 31, 2015 . Basis of Presentation Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Our Consolidated Balance Sheets at December 31, 2014 were retrospectively revised from previously reported amounts to reclassify those properties classified as held for sale as of December 31, 2015 . Our Consolidated Statements of Income for the years ended December 31, 2014 and 2013 were retrospectively revised from previously reported amounts to reclassify the operations for those properties classified as discontinued operations. 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 partnerships, joint ventures and limited liability companies when we control the major operating and financial policies of the entity through majority ownership or in our capacity as general partner or managing member. At December 31, 2015 , three of the 50.0% or less owned in-service office properties in a joint venture were consolidated. In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. During 2015 , we acquired three buildings and a land parcel using special purpose entities owned by qualified intermediaries to facilitate a potential Section 1031 reverse exchange under the Internal Revenue Code. To realize the tax deferral available under the Section 1031 exchange, we must complete the Section 1031 exchange, and take title to the to-be-exchanged buildings within 180 days of the acquisition date. We have determined that these entities are variable interest entities of which we are the primary beneficiary; and therefore, we consolidate these entities. As of December 31, 2015 , these variable interest entities had total assets, liabilities and cash flows of $421.3 million , $16.3 million , and $7.1 million , respectively. At December 31, 2014 , we had involvement with, but were not the primary beneficiary in, an entity that we concluded to be a variable interest entity. All intercompany transactions and accounts have been eliminated. 1. Description of Business and Significant Accounting Policies – Continued During the second quarter of 2015, as a result of our partner’s irrevocable exercise of a buy-sell provision in our SF-HIW Harborview Plaza, LP ("Harborview") joint venture agreement, our partner’s right to put its 80.0% equity interest back to us became no longer exercisable. As a result, we recorded the original contribution transaction as a partial sale and recognized $2.2 million of gain. Our investment in this joint venture then qualified for the equity method of accounting, which resulted in the retrospective revision of our Consolidated Balance Sheets and Consolidated Statements of Equity and Capital for all prior periods presented. Such retrospective revision is denoted using "as revised" in our Consolidated Financial Statements and accompanying notes. The effects of the retrospective application of the equity method of accounting to our Consolidated Statements of Income, Comprehensive Income and Cash Flows were not material. The effects of the retrospective application of the equity method of accounting to the Company's December 31, 2014 Balance Sheet were as follows: December 31, Increase/(Decrease) Net real estate assets $ (29,400 ) Investments in and advances to unconsolidated affiliates $ 23,614 Total Assets $ (5,786 ) Financing obligation $ (14,557 ) Distributions in excess of net income available for common stockholders $ 8,771 Total Liabilities, Noncontrolling Interests in the Operating Partnership and Equity $ (5,786 ) 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. Real Estate and Related Assets Real estate and related assets are recorded at cost and stated at cost less accumulated depreciation. Renovations, replacements and other expenditures that improve or extend the life of assets are capitalized and depreciated over their estimated useful lives. Expenditures for ordinary maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful life of 40 years for buildings and depreciable land infrastructure costs, 15 years for building improvements and five to seven years for furniture, fixtures and equipment. Tenant improvements are amortized using the straight-line method over initial fixed terms of the respective leases, which generally are from three to 10 years. Depreciation expense for real estate assets was $ 168.7 million , $ 154.4 million and $ 138.2 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and are stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction. 1. Description of Business and Significant Accounting Policies – Continued Expenditures directly related to the leasing of properties are included in deferred financing and leasing costs and are stated at amortized cost. Such expenditures are part of the investment necessary to execute leases and, therefore, are classified as investment activities in the statement of cash flows. All leasing commissions paid to third parties for new leases or lease renewals are capitalized. Internal leasing costs, which consist primarily of compensation, benefits and other costs, such as legal fees related to leasing activities, that are incurred in connection with successfully obtaining leases of properties are also capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases, which generally are from three to 10 years. Estimated costs related to unsuccessful activities are expensed as incurred. We record liabilities for the performance of asset retirement activities when the obligation to perform such activities is probable even when uncertainty exists about the timing and/or method of settlement. Upon the acquisition of real estate assets, we assess the fair value of acquired tangible assets such as land, buildings and tenant improvements, intangible assets and liabilities such as above and below market leases, acquired in-place leases, customer relationships and other identifiable intangible assets and assumed liabilities. We assess fair value based on estimated cash flow projections that utilize discount and/or capitalization rates as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. The above and below market rate portions of leases acquired in connection with property acquisitions are recorded in deferred financing and 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 financing and leasing costs and are amortized to depreciation and amortization expense over the remaining term of the respective lease. The value of in-place leases is based on our evaluation of the specific characteristics of each customer's lease. Factors considered include estimates of carrying costs during hypothetical expected lease-up periods, current market conditions, the customer's credit quality and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider tenant improvements, leasing commissions and legal and other related expenses. Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the sale of the asset is probable, has been duly approved by the Company, a legally enforceable contract has been executed and the buyer's due diligence period, if any, has expired. Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates With respect to assets classified as held for use, we perform an impairment analysis if events or changes in circumstances indicate that the carrying value may be impaired, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset's carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete. 1. Description of Business and Significant Accounting Policies – Continued If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and are subject to future events that may alter our assumptions, the discounted and/or undiscounted future operating and residual cash flows estimated by us in our impairment analyses or those established by appraisal may not be achieved and we may be required to recognize future impairment losses on properties held for use. We record assets held for sale at the lower of the carrying amount or estimated fair value. Fair value of assets held for sale is equal to the estimated or contracted sales price with a potential buyer, less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value. We also analyze our investments in unconsolidated affiliates for impairment. This analysis consists of determining whether an expected loss in market value of an investment is other than temporary by evaluating the length of time and the extent to which the market value has been less than cost, the financial condition and near-term prospects of the unconsolidated affiliate, and our intent and ability to retain our investment for a period of time sufficient to allow for any anticipated recovery in market value. As the factors used in this analysis are difficult to predict and are subject to future events that may alter our assumptions, we may be required to recognize future impairment losses on our investments in unconsolidated affiliates. Sales of Real Estate For sales transactions meeting the requirements for full profit recognition, 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. For sales transactions with continuing involvement after the sale, if the continuing involvement with the property is limited by the terms of the sales contract, profit is recognized at the time of sale and is reduced by the maximum exposure to loss related to the nature of the continuing involvement. Sales to entities in which we have or receive an interest are accounted for using partial sale accounting. For transactions that do not meet the criteria for a sale, we evaluate the nature of the continuing involvement, including put and call provisions, if present, and account for the transaction as a financing arrangement, profit-sharing arrangement, leasing arrangement or other alternate method of accounting, rather than as a sale, based on the nature and extent of the continuing involvement. Some transactions may have numerous forms of continuing involvement. In those cases, we determine which method is most appropriate based on the substance of the transaction. Rental and Other Revenues Minimum contractual rents from leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Contingent rental revenue, such as percentage rent, is accrued when the contingency is removed. Termination fee income is recognized at the later of when the customer has vacated the space or the lease has expired and a fully executed lease termination agreement has been delivered, the amount of the fee is determinable and collectability of the fee is reasonably assured. Rental revenue reductions related to co-tenancy lease provisions, if any, are accrued when events have occurred that trigger such provisions. 1. Description of Business and Significant Accounting Policies – Continued Cost recovery income is determined on a calendar year and a lease-by-lease basis. The most common types of cost recovery income in our leases are common area maintenance (“CAM”) and real estate taxes, for which a customer typically pays its pro-rata share of operating and administrative expenses and real estate taxes in excess of the costs incurred during a contractually specified base year. The computation of cost recovery income is complex and involves numerous judgments, including the interpretation of lease provisions. Leases are not uniform in dealing with such cost recovery income and there are many variations in the computation. Many customers make monthly fixed payments of CAM, real estate taxes and other cost reimbursement items. We accrue income related to these payments each month. We make quarterly accrual adjustments, positive or negative, to cost recovery income to adjust the recorded amounts to our best estimate of the final annual amounts to be billed and collected. After the end of the calendar year, we compute each customer's final cost recovery income and, after considering amounts paid by the customer during the year, issue a bill or credit for the appropriate amount to the customer. The differences between the amounts billed less previously received payments and the accrual adjustment are recorded as increases or decreases to cost recovery income when the final bills are prepared, which occurs during the first half of the subsequent year. Allowance for Doubtful Accounts Accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable are reduced by an allowance for amounts that may become uncollectible in the future. We regularly evaluate the adequacy of our allowance for doubtful accounts. The evaluation primarily consists of reviewing past due account balances and considering such factors as the credit quality of our customer, historical trends of the customer and changes in customer payment terms. Additionally, with respect to customers in bankruptcy, we estimate the probable recovery through bankruptcy claims and adjust the allowance for amounts deemed uncollectible. If our assumptions regarding the collectability of receivables prove incorrect, we could experience losses in excess of our allowance for doubtful accounts. The allowance and its related receivable are written-off when we have concluded there is a low probability of collection and we have discontinued collection efforts. Discontinued Operations Subsequent to the early adoption of the Financial Accounting Standards Board ("FASB") accounting standards update on the presentation of discontinued operations beginning in April 2014, 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. If the property is sold to a joint venture in which we retain an interest, the property will not be accounted for as a discontinued operation due to our significant ongoing interest in the operations through our joint venture interest. If we are retained to provide property management, leasing and/or other services for the property owner after the sale, the property generally will be accounted for as a discontinued operation because the expected cash flows related to our management and leasing activities generally will not be significant in comparison to the cash flows from the property prior to sale. Lease Incentives Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign a lease, are capitalized in deferred financing and leasing costs and amortized on a straight-line basis over the respective lease terms as a reduction of rental revenues. Investments in Unconsolidated Affiliates We account for our investments in less than majority owned joint ventures, partnerships and limited liability companies 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 entity. These investments are initially recorded at cost in 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. 1. Description of Business and Significant Accounting Policies – Continued 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, escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements and any deposits made with lenders to unencumber secured properties. 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 temporary differences between such income and the amount recognized for tax purposes. Concentration of Credit Risk At December 31, 2015 , properties that we wholly own were leased to 1,910 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Raleigh, NC, Atlanta, GA, Tampa, FL and Nashville, TN. Our customers engage in a wide variety of businesses. No single customer of the properties that we wholly own generated more than 6.0% of our consolidated revenues during 2015 . 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. 1. Description of Business and Significant Accounting Policies – Continued Derivative Financial Instruments We borrow funds at a combination of fixed and variable rates. Borrowings under our revolving credit facility, bridge facility and bank term loans bear interest at variable rates. Our long-term debt typically bears interest at fixed rates. Our interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and to lower our overall borrowing costs. To achieve these objectives, from time to time, we enter into interest rate hedge contracts such as collars, swaps, caps and treasury lock agreements in order to mitigate our interest rate risk with respect to various debt instruments. We generally do not hold or issue these derivative contracts for trading or speculative purposes. The interest rate on all of our variable rate debt is generally adjusted at one or three month intervals, subject to settlements under these interest rate hedge contracts. Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive loss ("AOCL") and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings. We account for terminated derivative instruments by recognizing the related accumulated comprehensive income/loss balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated comprehensive income/loss into earnings over the originally designated hedge period. Earnings Per Share and Per Unit Basic earnings per share of the Company is computed by dividing net income available for common stockholders by the weighted Common Shares outstanding - basic. Diluted earnings per share is computed by dividing net income available to common stockholders plus noncontrolling interests in the Operating Partnership by the weighted Common Shares outstanding - basic plus the dilutive effect of options, warrants and convertible securities outstanding, including Common Units, using the treasury stock method. Weighted Common Shares outstanding - basic includes all unvested restricted stock where dividends received on such restricted stock are non-forfeitable. Basic earnings per unit of the Operating Partnership is computed by dividing net income available for common unitholders by the weighted Common Units outstanding - basic. Diluted earnings per unit is computed by dividing net income available to common unitholders by the weighted Common Units outstanding - basic plus the dilutive effect of options and warrants, using the treasury stock method. Weighted Common Units outstanding - basic includes all of the Company's unvested restricted stock where dividends received on such restricted stock are non-forfeitable. Recently Issued Accounting Standards The FASB recently issued an accounting standards update that requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The accounting standards update is required to be adopted in 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. We are in the process of evaluating this accounting standards update. The FASB recently issued an accounting standards update that amends consolidation requirements. The amendments significantly change the consolidation analysis required under GAAP and will require companies to reevaluate all previous consolidation conclusions. The accounting standards update is required to be adopted in 2016. We are in the process of evaluating this accounting standards update. The FASB recently issued an accounting standards update that requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The accounting standards update is required to be adopted in 2016. Retrospective application is required. We do not expect such adoption to have a material effect on the balance sheet.

Real Estate [Abstract]
Real Estate Assets	Real Estate Assets Acquisitions During 2015, we acquired: • a building in Tampa, FL encompassing 528,000 rentable square feet for a net purchase price of $113.5 million and an adjacent land parcel for a purchase price of $2.2 million; • two buildings in Atlanta, GA encompassing 896,000 rentable square feet for a net purchase price of $290.3 million; • land in Atlanta, GA for a purchase price and related transaction costs of $5.2 million (including contingent consideration of $0.9 million); and • our Highwoods DLF 98/29, LLC joint venture partner’s 77.2% interest in a building in Orlando, FL encompassing 168,000 rentable square feet in exchange for the assumption of secured debt recorded at fair value of $19.3 million (see Note 6). We expensed $1.0 million of acquisition costs (included in general and administrative expenses) in 2015 related to these acquisitions. The assets acquired and liabilities assumed were recorded at fair value as determined by management based on information available at the acquisition date and on current assumptions as to future operations. The following table sets forth a summary of the fair value of the major assets acquired and liabilities assumed relating to the above-referenced acquisition of two buildings in Atlanta, GA during 2015: Total Purchase Price Allocation Real estate assets $ 275,639 Acquisition-related intangible assets (in deferred financing and leasing costs) 23,722 Acquisition-related below market lease liabilities (in accounts payable, accrued expenses and other liabilities) (9,076 ) Total allocation $ 290,285 The following table sets forth the Company's revenues and net income, adjusted for interest expense, straight-line rental income, depreciation and amortization related to purchase price allocations and acquisition costs, assuming the above-referenced acquisition of two buildings in Atlanta, GA during 2015 had been completed as of January 1, 2014: Year Ended December 31, 2015 2014 (unaudited) Pro forma revenues $ 626,067 $ 584,650 Pro forma net income $ 103,485 $ 113,284 Pro forma net income available for common stockholders $ 96,797 $ 105,769 Pro forma earnings per share - basic $ 1.03 $ 1.17 Pro forma earnings per share - diluted $ 1.02 $ 1.17 The above-referenced acquisition of two buildings in Atlanta, GA during 2015 resulted in revenues of $7.3 million and net loss of $1.2 million recorded in the Consolidated Statements of Income for the year ended December 31, 2015. 2. Real Estate Assets - Continued During 2014, we acquired: • a building in Orlando, FL encompassing 246,000 rentable square feet for a purchase price of $67.4 million; • our partner's 50.0% interest in a building owned by our consolidated Highwoods-Markel Associates, LLC joint venture in Richmond, VA encompassing 66,000 rentable square feet for a purchase price of $4.2 million, which is recorded as acquisition of noncontrolling interest in consolidated affiliate; • land in Nashville, TN for a purchase price and related transaction costs of $15.8 million (including contingent consideration of $3.3 million); and • a building in Raleigh, NC encompassing 374,000 rentable square feet for a purchase price of $83.8 million. We expensed $0.5 million of acquisition costs (included in general and administrative expenses) in 2014 related to these acquisitions. The assets acquired and liabilities assumed were recorded at fair value as determined by management based on information available at the acquisition date and on current assumptions as to future operations. During 2013, we acquired: • our joint venture partner's 60.0% interest in our HIW-KC Orlando, LLC joint venture, which owned five buildings in Orlando, FL encompassing 1.3 million rentable square feet, for a net purchase price of $112.8 million. We previously accounted for our 40.0% interest in this joint venture using the equity method of accounting. The assets and liabilities of the joint venture are now wholly owned and are recorded in our Consolidated Financial Statements, including assets recorded at fair value of $188.0 million and secured debt recorded at fair value of $127.9 million, with an effective interest rate of 3.11%. This debt has since been repaid. As a result of acquiring a controlling interest in this joint venture, our previously held equity interest was remeasured at a fair value of $75.2 million resulting in a gain of $7.5 million, which represents the difference between the fair market value of our previously held equity interest and the carrying value of our investment on the date of acquisition. The fair market value of our previously held equity interest was determined by management based on information available at the acquisition date and on current assumptions as to future operations; • a building in Nashville, TN encompassing 520,000 rentable square feet for a net purchase price of $150.1 million; • our Highwoods DLF 97/26 DLF 99/32, LP joint venture partner's 57.0% interest in two buildings in Atlanta, GA encompassing 505,000 rentable square feet for a net purchase price of $44.5 million, including the assumption of secured debt recorded at fair value of $37.6 million, with an effective interest rate of 3.34%. This debt has since been repaid; • a building in Atlanta, GA encompassing 553,000 rentable square feet for a purchase price of $140.1 million; • two buildings in Tampa, FL encompassing 372,000 rentable square feet for a purchase price of $52.5 million; • two buildings in Greensboro, NC encompassing 195,000 rentable square feet for a purchase price of $30.8 million; and • land in Memphis, TN for a purchase price of $4.8 million. We expensed $1.8 million of acquisition costs (included in general and administrative expenses) in 2013 related to these acquisitions. The assets acquired and liabilities assumed were recorded at fair value as determined by management based on information available at the acquisition date and on current assumptions as to future operations. 2. Real Estate Assets - Continued The following table sets forth a summary of the fair value of the major assets acquired and liabilities assumed relating to the above-referenced acquisitions of a building in Orlando, FL and Nashville, TN and the 553,000 rentable square foot building in Atlanta, GA during 2013: Total Purchase Price Allocation Real estate assets $ 445,396 Acquisition-related intangible assets (in deferred financing and leasing costs) 50,595 Mortgages and notes payable (127,891 ) Acquisition-related below market lease liabilities (in accounts payable, accrued expenses and other liabilities) (17,818 ) Total allocation $ 350,282 The following table sets forth the Company's revenues and net income, adjusted for interest expense, straight-line rental income, depreciation and amortization related to purchase price allocations, acquisition costs and equity in earnings of unconsolidated affiliates previously recognized as income assuming the above-referenced acquisitions of buildings in Orlando, FL, Nashville, TN and Atlanta, GA during 2013 had been completed as of January 1, 2012: Year Ended December 31, 2013 (unaudited) Pro forma revenues $ 538,890 Pro forma net income $ 121,754 Pro forma net income available for common stockholders $ 113,606 Pro forma earnings per share - basic $ 1.33 Pro forma earnings per share - diluted $ 1.33 The above-referenced acquisitions of buildings in Orlando, FL, Nashville, TN and Atlanta, GA during 2013 resulted in revenues of $25.0 million and net losses of $0.2 million recorded in the Consolidated Statements of Income for the year ended December 31, 2013. Dispositions During 2015, we sold a total of three buildings and land for an aggregate sale price of $27.8 million and recorded aggregate gains on disposition of property of $9.2 million, net of $0.5 million in taxes payable by our taxable REIT subsidiary. During 2014, we sold a total of 33 buildings and land for an aggregate sale price of $187.3 million (before closing credits to buyer of $8.6 million for unfunded building and tenant improvements and $2.9 million for free rent) and recorded aggregate gains on disposition of property of $44.4 million. During 2013, we sold a total of 47 buildings and land for an aggregate sale price of $260.5 million (before closing credits to buyer of $3.6 million for unfunded tenant improvements and after $2.0 million in closing credits to buyer for free rent) and recorded aggregate gains on disposition of discontinued operations of $62.3 million. Additionally, in connection with the disposition of a building in 2012, we had the right to receive additional cash consideration of up to $1.5 million upon the satisfaction of a certain post-closing requirement. The post-closing requirement was satisfied and the cash consideration was received during 2013. Accordingly, we recognized $1.5 million in additional gain on disposition of discontinued operations in 2013. 2. Real Estate Assets - Continued Impairments During 2014, we recorded an impairment of real estate assets of $0.6 million on a building in Greensboro, NC. During 2013, we recorded impairments of real estate assets of $1.1 million on four buildings in a single office park in Winston-Salem, NC and $1.1 million on seven buildings in Atlanta, GA. These impairments were due to a change in the assumed timing of future dispositions and leasing assumptions, which reduced the future expected cash flows from the impaired properties.

Receivables [Abstract]
Mortgages and Notes Receivable	Mortgages and Notes Receivable Mortgages and notes receivable were $2.1 million and $13.1 million at December 31, 2015 and 2014 , respectively. During 2010, we provided seller financing in conjunction with two disposition transactions. We accounted for these dispositions using the installment method, whereby a gain on disposition of property was deferred until the seller financing was repaid. During 2014 , the $16.5 million of seller financing was fully repaid and the resultant $0.4 million gain on disposition of property was recorded. During 2012, we provided $8.6 million of secured acquisition financing to a third party. We also agreed to loan such third party $8.4 million on a secured basis to fund future infrastructure development. During 2015 , $9.9 million of the secured acquisition financing was repaid, including accrued interest. Previously, we concluded this arrangement to be an interest in a variable interest entity. However, since we did not have the power to direct matters that most significantly impact the activities of the entity, we did not qualify as the primary beneficiary. Accordingly, the entity was not consolidated. Our risk of loss with respect to this arrangement was limited to the carrying value of the mortgage receivable. We evaluate the ability to collect our mortgages and notes receivable by monitoring the leasing statistics and/or market fundamentals of these assets. As of December 31, 2015 , our mortgages and notes receivable were not in default and there were no other indicators of impairment.

As our cost basis was different from the basis reflected at the entity level, we recorded a net impairment charge on our investment of $0.4 million. This charge represented the other-than-temporary decline in the fair value below the carrying value of our investment. Our 49.0% interest in Board of Trade was redeemed in exchange for $4.7 million in cash. - Highwoods KC Glenridge Office, LLC ("KC Glenridge Office") and Highwoods KC Glenridge Land, LLC ("KC Glenridge Land") During 2015, KC Glenridge Office and KC Glenridge Land collectively sold two buildings and land to an unrelated third party for an aggregate sale price of $24.5 million (before closing credits to buyer of $0.3 million for unfunded tenant improvements) and recorded gains on disposition of property of $2.4 million. We recorded $0.9 million as our share of these gains through equity in earnings of unconsolidated affiliates. During 2014, KC Glenridge Office paid at maturity the remaining $14.9 million balance on a secured mortgage loan with an effective interest rate of 4.84%. - HIW-KC Orlando, LLC See Note 2 for a description of our acquisition of our partner's 60.0% equity interest in this joint venture during 2013. 4. Investments in and Advances to Affiliates – Continued - Lofts at Weston, LLC ("Weston Lofts") During 2011, we and Ravin Partners, LLC (“Ravin”) formed Weston Lofts, in which we had a 50.0% ownership interest. We contributed 15.0 acres of land at an agreed upon value of $2.4 million to this joint venture, and Ravin contributed $1.2 million in cash and agreed to guarantee the joint venture's development loan. The joint venture then distributed $1.2 million to us and we recorded a gain of $0.3 million on this transaction. Ravin was the developer, manager and leasing agent and received customary fees from the joint venture, which constructed 215 residential units at a total cost of $25.9 million. During 2013, Weston Lofts sold the 215 residential units to an unrelated third party for gross proceeds of $38.3 million and recorded a gain of $12.2 million. As a result, we received aggregate net distributions of $9.4 million and recorded our share of the gain of $3.2 million, which is net of $1.7 million in taxes incurred by our taxable REIT subsidiary, in equity in earnings of unconsolidated affiliates. Our share of the gain was less than 50.0% due to Ravin's preferred return as the developer. - Highwoods DLF 97/26 DLF 99/32, LP (“DLF II”) During 2015, DLF II sold a building to an unrelated third party for a sale price of $7.0 million and recorded a gain on disposition of property of $2.1 million. We recorded $1.1 million as our share of this gain through equity in earnings of unconsolidated affiliates. See Note 2 for a description of our acquisition of two buildings in Atlanta, GA from DLF II during 2013. During 2013, DLF II sold a building to an unrelated third party for a sale price of $10.1 million (after $0.3 million in closing credits to buyer for free rent) and recorded a gain on disposition of property of less than $0.1 million. As our cost basis was different from the basis reflected at the joint venture level, we recorded $0.4 million of gain through equity in earnings of unconsolidated affiliates. - Kessinger/Hunter & Company, LC ("Kessinger/Hunter") Kessinger/Hunter, which is managed by our joint venture partner, provides leasing services, among other things, to certain buildings that we wholly own in Kansas City, MO in exchange for customary fees from us. Kessinger/Hunter received $ 0.3 million , $ 0.6 million and $ 0.2 million from us for these services in 2015 , 2014 and 2013 , respectively. - Highwoods DLF Forum, LLC (“Forum”) During 2013, Forum obtained a $71.7 million, five-year secured mortgage loan from a third party lender, bearing a floating interest rate of LIBOR plus 190 basis points, which was used by the joint venture to repay a secured loan at maturity to a third party lender. This loan is scheduled to mature in November 2018. - Highwoods DLF 98/29, LLC (“DLF I”) See Note 2 for a description of our acquisition of a building in Orlando, FL from DLF I during 2015. The joint venture recorded a gain on disposition of property of $13.7 million. Our share of $3.1 million was recorded as a reduction to real estate assets. During 2014, DLF I sold a building to an unrelated third party for a sale price of $13.7 million (before $0.4 million in closing credits to buyer for free rent) and recorded a gain on disposition of property of $1.0 million. We recorded $0.2 million as our share of this gain through equity in earnings of unconsolidated affiliates. During 2013, DLF I sold a building to an unrelated third party for a sale price of $5.9 million (after $0.1 million in closing credits to buyer for free rent) and recorded a gain on disposition of discontinued operations of less than $0.1 million. We recorded less than $0.1 million as our share of this gain through equity in earnings of unconsolidated affiliates. 4. Investments in and Advances to Affiliates – Continued During 2013, DLF I recorded impairments of real estate assets of $20.1 million on buildings in Orlando, FL, Atlanta, GA and Charlotte, NC. We recorded $4.5 million as our share of these impairment charges through equity in earnings of unconsolidated affiliates. These impairments were due to a change in the assumed timing of future dispositions and/or leasing assumptions, which reduced the future expected cash flows from the impaired properties. - 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, 2015 , 2014 and 2013 , we recognized $ 1.4 million , $ 1.2 million and $ 2.9 million , respectively, of development/construction, management and leasing fees from our unconsolidated joint ventures. At December 31, 2015 and 2014 , we had receivables of $0.1 million and $0.5 million, respectively, related to these fees in accounts receivable. Consolidated Affiliates The following summarizes our consolidated affiliates: - Highwoods-Markel Associates, LLC (“Markel”) We have a 50.0% ownership interest in Markel. We are the manager and leasing agent for Markel's properties, which are located in Richmond, VA in exchange for customary management and leasing fees. We consolidate Markel since we are the managing member and control the major operating and financial policies of the entity. As controlling member, we have an obligation to cause this property-owning entity to distribute proceeds of liquidation to the noncontrolling interest member in these partially owned properties only if the net proceeds received by the entity from the sale of Markel's assets warrant a distribution as determined by the governing agreement. We estimate the value of noncontrolling interest distributions would have been $ 19.4 million had the entity been liquidated at December 31, 2015 . This estimated settlement value is based on the fair value of the underlying properties which is based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates and costs to operate each property. If the entity's underlying assets are worth less than the underlying liabilities on the date of such liquidation, we would have no obligation to remit any consideration to the noncontrolling interest holder. See Note 2 for a description of our acquisition of the noncontrolling member's 50.0% interest in a building owned by Markel during 2014. - Harborview We had a 20.0% interest in Harborview, which had been accounted for as a financing obligation since our partner had the right to put its 80.0% equity interest back to us any time prior to September 11, 2015. During 2012, we also provided a three-year $20.8 million interest-only secured loan to Harborview that was scheduled to mature in September 2015. During the second quarter of 2015, as a result of our partner’s irrevocable exercise of a buy-sell provision in our Harborview joint venture agreement, our partner’s right to put its 80.0% equity interest back to us became no longer exercisable, which resulted in recording the original contribution transaction as a partial sale. As a result, we were required to begin accounting for Harborview using the equity method of accounting. See Note 1. During the third quarter of 2015, we sold our 20.0% interest in Harborview to our partner for net proceeds of $6.9 million and recorded a $4.2 million gain on disposition of investment in unconsolidated affiliate. The $20.8 million interest-only secured loan previously provided by us to Harborview was paid in full upon consummation of the sale.

(11) As more fully described in Note 7, we entered into floating-to-fixed interest rate swaps that effectively fix LIBOR for the original $225.0 million portion of this loan. Accordingly, the equivalent fixed rate of this amount is 2.78% . The interest rate on the remaining $125.0 million is 1.41% at December 31, 2015 . (12) The interest rate is 1.49% at December 31, 2015 . (13) The interest rate is 1.45% at December 31, 2015 . 6. Mortgages and Notes Payable - Continued The following table sets forth scheduled future principal payments, including amortization, due on our mortgages and notes payable at December 31, 2015 : Years Ending December 31, Principal Amount 2016 $ 396,090 2017 507,345 2018 498,305 2019 199,305 2020 349,305 Thereafter 549,264 $ 2,499,614 Our $ 475.0 million unsecured revolving credit facility is scheduled to mature in January 2018 and includes an accordion feature that allows for an additional $ 75.0 million of borrowing capacity subject to additional lender commitments. Assuming no defaults have occurred, we have an option to extend the maturity for two additional six-month periods. The interest rate at our current credit ratings is LIBOR plus 110 basis points and the annual facility fee is 20 basis points. There was $ 299.0 million and $ 313.7 million outstanding under our revolving credit facility at December 31, 2015 and January 29, 2016 , respectively. At both December 31, 2015 and January 29, 2016 , we had $ 0.2 million of outstanding letters of credit, which reduces the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility at December 31, 2015 and January 29, 2016 was $ 175.8 million and $ 161.1 million , respectively. During 2015, we prepaid without penalty a secured mortgage loan with a fair market value of $5.9 million with an effective interest rate of 7.65% that was originally scheduled to mature in February 2016, the remaining $106.0 million balance on a secured mortgage loan with an effective interest rate of 6.88% that was originally scheduled to mature in January 2016 and the remaining $39.4 million balance on a secured mortgage loan with an effective interest rate of 6.43% that was originally scheduled to mature in November 2015. We recorded aggregate losses on debt extinguishment of $0.2 million related to these prepayments. Real estate assets having a gross book value of approximately $293 million became unencumbered in connection with the payoff of these secured loans. We also paid down $4.9 million of secured loan balances through principal amortization during 2015. During 2015, we obtained a $350.0 million, six-month unsecured bridge facility. The bridge facility is originally scheduled to mature on March 28, 2016. Assuming no defaults have occurred, we have an option to extend the maturity for an additional six-month period. The interest rate on the bridge facility at our current credit ratings is LIBOR plus 110 basis points. There was $350.0 million outstanding under our bridge facility at December 31, 2015. We intend to repay this facility in the first quarter of 2016. During 2015, we amended our $225.0 million, seven-year unsecured bank term loan, which was scheduled to mature in January 2019. We increased the borrowed amount to $350.0 million. The amended term loan is now scheduled to mature in June 2020 and the interest rate, based on our current credit ratings, was reduced from LIBOR plus 175 basis points to LIBOR plus 110 basis points. We incurred $1.3 million of deferred financing fees in connection with this amendment, which will be amortized along with existing unamortized deferred loan fees over the remaining term of the new loan. 6. Mortgages and Notes Payable - Continued During 2015, we acquired our joint venture partner’s 77.2% interest in a building in Orlando, FL. Simultaneously with this acquisition, the joint venture's previously existing mortgage note was restructured into a new $18.0 million first mortgage note and a $10.2 million subordinated note, both of which are scheduled to mature in July 2017. The first mortgage note is interest only with an effective interest rate of 5.36%, payable monthly. The subordinated note has an effective interest rate of 8.6%. Additionally, we deposited $3.0 million into escrow to fund tenant improvements, leasing commissions and building improvements. The first mortgage note and subordinated note can be prepaid at any time commencing October 2016 upon a sale or refinancing of the property. In such event, the subordinated note and any and all accrued interest thereon would be deemed fully satisfied upon payment of a "waterfall payment," if any. Such "waterfall payment" would be a cash payment equal to 50.0% of the amount, if any, by which the net sale proceeds or appraised value in the event of a refinancing exceeds (1) the outstanding principal of the first mortgage note, (2) the funds deposited by us into escrow to fund tenant improvements, leasing commissions and building improvements and (3) a 10.0% return on such funds deposited by us into escrow. The fair value of the first mortgage note was $18.3 million and the fair value of the subordinated note equaled the projected waterfall payment of $1.0 million. During 2014, the Operating Partnership issued $300 million aggregate principal amount of 3.20% Notes due June 15, 2021, less original issue discount of $3.1 million. These notes were priced at 98.983% for an effective yield of 3.363%. Underwriting fees and other expenses were incurred that aggregated $2.4 million; these costs were deferred and will be amortized over the term of the notes. During 2014, we prepaid the remaining $36.9 million balance on a secured mortgage loan with an effective interest rate of 3.34% that was originally scheduled to mature in April 2015. We recorded $0.3 million of loss on debt extinguishment related to this prepayment. We also prepaid without penalty the remaining $123.7 million balance on a secured mortgage loan with an effective interest rate of 3.11% that was originally scheduled to mature in July 2014 and the remaining $7.2 million balance on a secured mortgage loan with an effective interest rate of 3.32% that was originally scheduled to mature in August 2014. We recorded less than $0.1 million of gain on debt extinguishment related to this last prepayment. During 2013, we prepaid without penalty a secured mortgage loan with a fair market value of $67.5 million bearing an effective interest rate of 5.12% that was originally scheduled to mature in January 2014. We also prepaid without penalty the remaining $114.7 million balance on two secured mortgage loans bearing interest at a weighted average rate of 5.75% that were originally scheduled to mature in December 2013. We recorded less than $0.1 million of loss on debt extinguishment related to these prepayments. During 2013, one of our consolidated affiliates also prepaid without penalty the remaining $32.3 million balance on four secured mortgage loans bearing interest at a weighted average rate of 5.79% that were originally scheduled to mature in January 2014. During 2013, we prepaid the remaining $35.0 million balance on a $200.0 million unsecured bank term loan that was originally scheduled to mature in February 2016. We recorded $0.2 million of loss on debt extinguishment related to this prepayment. We are currently in compliance with financial covenants and other requirements with respect to our consolidated debt. Our revolving credit facility, bridge 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. The Operating Partnership has $379.5 million carrying amount of 2017 bonds outstanding, $200.0 million carrying amount of 2018 bonds outstanding, $297.6 million carrying amount of 2021 bonds outstanding and $248.2 million carrying amount of 2023 bonds outstanding. The indenture that governs these outstanding notes requires us to comply with customary operating covenants and various financial ratios. The trustee or the holders of at least 25.0% in principal amount of either series of bonds can accelerate the principal amount of such series upon written notice of a default that remains uncured after 60 days. Capitalized Interest Total interest capitalized to development and significant building and tenant improvement projects was $ 6.9 million , $ 5.3 million and $ 2.7 million for the years ended December 31, 2015 , 2014 and 2013 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We have six floating-to-fixed interest rate swaps through January 2019 each with respect to an aggregate of $225.0 million LIBOR-based borrowings. These swaps effectively fix the underlying LIBOR rate at a weighted average of 1.678% . The counterparties under the swaps are major financial institutions. The swap agreements contain a provision whereby if we default on any of our indebtedness, if greater than $10.0 million , and which default results in repayment of such indebtedness being, or becoming capable of being, accelerated by the lender, then we could also be declared in default on our swaps. These swaps have been designated and accounted for as cash flow hedges with changes in fair value recorded in other comprehensive income/(loss) each reporting period. No gain or loss was recognized related to hedge ineffectiveness or to amounts excluded from effectiveness testing on our cash flow hedges during the year ended December 31, 2015 . We have no collateral requirements related to our interest rate swaps. Amounts reported in AOCL related to derivatives will be reclassified to interest expense as interest payments are made on our variable rate debt. During 2016 , we estimate that $2.3 million will be reclassified to interest expense. The following table sets forth the fair value of our derivatives: December 31, 2015 2014 Derivatives: Derivatives designated as cash flow hedges in accounts payable, accrued expenses and other liabilities: Interest rate swaps $ 3,073 $ 2,412 The following table sets forth the effect of our cash flow hedges on AOCL and interest expense: Year Ended December 31, 2015 2014 2013 Derivatives Designated as Cash Flow Hedges: Amount of unrealized gains/(losses) recognized in AOCL on derivatives (effective portion): Interest rate swaps $ (4,040 ) $ (5,662 ) $ 5,778 Amount of losses reclassified out of AOCL into contractual interest expense (effective portion): Interest rate swaps $ 3,696 $ 3,777 $ 3,370

Financing Arrangement [Abstract]
Financing Arrangement	Financing Arrangement In connection with tax increment financing for a parking garage we constructed in 1999, we are obligated to pay fixed special assessments over a 20-year period ending in 2019 . The net present value of these assessments, discounted at the 6.93% interest rate on the underlying tax increment financing, is recorded as a financing obligation and is classified in liabilities held for sale on our Consolidated Balance Sheets. We receive special tax revenues and property tax rebates recorded in interest and other income, which are intended, but not guaranteed, to provide funds to pay the special assessments. We acquired the related tax increment financing bond in a privately negotiated transaction in 2007 . Under the definitive agreements, dated as of December 21, 2015, relating to the sale of substantially all of our wholly-owned Country Club Plaza assets in Kansas City, MO (which we refer to as the "Plaza assets"), this tax increment financing bond will be assigned to the buyer of the Plaza assets as of the closing date at the agreed upon value of the principal amount and accrued interest, if any, then outstanding. Such value is included as part of the $660.0 million purchase price for the Plaza assets. This tax increment financing bond is classified in liabilities held for sale on our Consolidated Balance Sheets and was $7.4 million and $9.0 million at December 31, 2015 and 2014 , respectively. For additional information about this tax increment financing bond, see Notes 11 and 16.

Commitments and Contingencies	Commitments and Contingencies Operating Ground Leases Certain of our properties are subject to operating ground leases. Rental payments on these leases are adjusted periodically based on either the consumer price index or on a pre-determined schedule. Total rental property expense recorded for operating ground leases was $3.4 million , $3.4 million and $2.8 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. The following table sets forth our scheduled obligations for future minimum payments on operating ground leases at December 31, 2015 : Years Ending December 31, Minimum Payments 2016 $ 3,033 2017 3,067 2018 3,103 2019 3,140 2020 3,179 Thereafter 109,157 $ 124,679 Lease and Contractual Commitments We have $340.0 million of lease and contractual commitments at December 31, 2015 . Lease and contractual commitments represent commitments under signed leases and contracts for operating properties (excluding tenant-funded tenant improvements) and contracts for development/redevelopment projects, of which $55.9 million was recorded on our Consolidated Balance Sheet at December 31, 2015 . Contingent Consideration In 2015, we acquired development land in Atlanta, GA for a purchase price and related transaction costs of $5.2 million, which includes contingent consideration estimated to be $0.9 million. The contingent consideration is payable in cash to a third party thirty days subsequent to stabilization, which is projected to be in the second quarter of 2019, if and to the extent the stabilized value of the building constructed on the development site exceeds the total development cost. In 2014, we acquired development land in Nashville, TN for a purchase price and related transaction costs of $15.8 million, which includes contingent consideration estimated to be $3.3 million. The contingent consideration is payable in cash to a third party no later than the first quarter of 2020 if and to the extent the stabilized value of the building constructed on the development site exceeds the total development cost. Closure of Division Office In the third quarter of 2015, we announced our intent to list for sale the Plaza assets. The Plaza assets consist of 776,000 square feet of in-service retail space, 468,000 square feet of in-service office space and a 28,000 square foot retail redevelopment project. We intend to close our Kansas City division office upon such sale, which is scheduled to occur on March, 1, 2016. In the fourth quarter of 2015, we accrued $1.6 million of the total $2.6 million severance costs expected to be incurred in connection with the sale. 9. Commitments and Contingencies - Continued Environmental Matters Substantially all of our in-service and development properties have been subjected to Phase I environmental assessments and, in certain instances, Phase II environmental assessments. Such assessments and/or updates have not revealed, nor are we aware of, any environmental liability that we believe would have a material adverse effect on our Consolidated Financial Statements. Litigation, Claims and Assessments We are from time to time a party to a variety of legal proceedings, claims and assessments arising in the ordinary course of our business. We regularly assess the liabilities and contingencies in connection with these matters based on the latest information available. For those matters where it is probable that we have incurred or will incur a loss and the loss or range of loss can be reasonably estimated, the estimated loss is accrued and charged to income in our Consolidated Financial Statements. In other instances, because of the uncertainties related to both the probable outcome and amount or range of loss, a reasonable estimate of liability, if any, cannot be made. Based on the current expected outcome of such matters, none of these proceedings, claims or assessments is expected to have a material effect on our business, financial condition, results of operations or cash flows.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Noncontrolling Interests in Consolidated Affiliates At December 31, 2015 , our noncontrolling interests in consolidated affiliates relate to our joint venture partner's 50.0% interest in office properties in Richmond, VA. Our joint venture partner is an unrelated third party. Noncontrolling Interests in the Operating Partnership Noncontrolling interests in the Operating Partnership relate to the ownership of Redeemable Common Units. Net income attributable to noncontrolling interests in the Operating Partnership is computed by applying the weighted average percentage of Redeemable Common Units during the period, as a percent of the total number of outstanding Common Units, to the Operating Partnership’s net income for the period after deducting distributions on Preferred Units. When a noncontrolling unitholder redeems a Common Unit for a share of Common Stock or cash, the noncontrolling interests in the Operating Partnership are reduced and the Company’s share in the Operating Partnership is increased by the fair value of each security at the time of redemption. The following table sets forth the Company's noncontrolling interests in the Operating Partnership: Year Ended December 31, 2015 2014 Beginning noncontrolling interests in the Operating Partnership $ 130,048 $ 106,480 Adjustment of noncontrolling interests in the Operating Partnership to fair value 67 25,275 Conversions of Common Units to Common Stock (1,645 ) (162 ) Redemptions of Common Units — (93 ) Net income attributable to noncontrolling interests in the Operating Partnership 2,918 3,542 Distributions to noncontrolling interests in the Operating Partnership (4,959 ) (4,994 ) Total noncontrolling interests in the Operating Partnership $ 126,429 $ 130,048 10.

Fair Value Disclosures [Abstract]
Disclosure About Fair Value of Financial Instruments	Disclosure About Fair Value of Financial Instruments The following summarizes the three levels of inputs that we use to measure fair value. Level 1. Quoted prices in active markets for identical assets or liabilities. Our Level 1 asset is our investment in marketable securities that we use to pay benefits under our non-qualified deferred compensation plan. Our Level 1 liability is our non-qualified deferred compensation obligation. The Company's Level 1 noncontrolling interests in the Operating Partnership relate to the ownership of Common Units by various individuals and entities other than the Company. Level 2. Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Our Level 2 asset is the fair value of certain 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 LIBOR interest rates (forward curves) derived from observed market LIBOR interest rate curves. In addition, credit valuation adjustments are considered in the fair values to account for potential nonperformance risk, but were concluded to not be significant inputs to the calculation for the periods presented. Level 3. Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Our Level 3 assets include (1) certain of our mortgages and notes receivable, which were estimated by the income approach utilizing internal cash flow projections and market interest rates to estimate the price that would be paid in an orderly transaction between market participants, and (2) our tax increment financing bond, which is not routinely traded but whose fair value is determined by the income approach utilizing contractual cash flows and market-based interest rates to estimate the projected redemption value based on quoted bid/ask prices for similar unrated municipal bonds. 11. Disclosure About Fair Value of Financial Instruments – Continued Our Level 3 liability is the fair value of our financing obligation, which was estimated by the income approach to approximate the price that would be paid in an orderly transaction between market participants, utilizing: (1) contractual cash flows; (2) market-based interest rates; and (3) a number of other assumptions including demand for space, competition for customers, changes in market rental rates, costs of operation and expected ownership periods. The following table sets forth our assets and liabilities and the Company's noncontrolling interests in the Operating Partnership that are measured at fair value within the fair value hierarchy.

Disclosure About Fair Value of Financial Instruments – Continued The following table sets forth the changes in our Level 3 asset, which is recorded at fair value on our Consolidated Balance Sheets: December 31, 2015 2014 Asset: Tax Increment Financing Bond: Beginning balance $ 12,447 $ 13,403 Principal repayment (1,695 ) (1,540 ) Unrealized gains (in AOCL) 445 584 Ending balance $ 11,197 $ 12,447 During 2007, we acquired a tax increment financing bond associated with a parking garage developed by us. This bond amortizes to maturity in 2020 . The estimated fair value at December 31, 2015 was equal to the outstanding principal due on the bond. If the discount rate used to fair value this bond was 100 basis points higher or lower, the fair value of the bond would have been $0.3 million lower or $0.3 million higher, respectively, as of December 31, 2015 . Payment of the principal and interest for the bond is guaranteed by us. We have recorded no credit losses related to the bond during the years ended December 31, 2015 and 2014 . There is no legal right of offset with the liability, which we report as a financing obligation, related to this tax increment financing bond. See Note 8. During 2014, we recorded an impairment of real estate assets on a building, which was subsequently sold during the year, based upon fair value at the time of impairment of $4.9 million . The impaired real estate asset was deemed to be a Level 3 asset and valued based primarily on market-based inputs and our assumptions about the use of the asset, as observable inputs were not available. In the absence of observable inputs, we estimate the fair value of real estate using unobservable data such as estimated discount and capitalization rates. We also utilize local and national industry market data such as comparable sales, sales contracts and appraisals to assist us in our estimation of fair value. Significant increases or decreases in any valuation inputs in isolation would result in a significantly lower or higher fair value measurement. The following table sets forth quantitative information about the unobservable inputs of our Level 3 assets, which were recorded at fair value on our Consolidated Balance Sheets: Valuation Technique Unobservable Input Rate/ Percentage 2015 Asset: Tax increment financing bond Income approach Discount rate 6.93% 2014 Assets: Tax increment financing bond Income approach Discount rate 8.4% Impaired real estate assets Income approach Capitalization rate 9.5% Discount rate 10.0%

Equity	Equity Common Stock Issuances During 2015 and 2014, the Company issued 2,922,905 and 2,500,031 shares, respectively, of Common Stock in public offerings and received net proceeds of $124.9 million and $104.1 million , respectively. At December 31, 2015 , the Company had 103.9 million remaining shares of Common Stock authorized to be issued under its charter. Common Stock Dividends Dividends of the Company declared and paid per share of Common Stock aggregated $1.70 for each of the years ended December 31, 2015 , 2014 and 2013 . The following table sets forth the Company's estimated taxability to the common stockholders of dividends per share for federal income tax purposes: Year Ended December 31, 2015 2014 2013 Ordinary income $ 1.50 $ 1.31 $ 1.28 Capital gains 0.13 0.29 0.26 Return of capital 0.07 0.10 0.16 Total $ 1.70 $ 1.70 $ 1.70 The Company's tax returns have not been examined by the Internal Revenue Service (“IRS”) and, therefore, the taxability of dividends is subject to change.

Warrants At December 31, 2015 and 2014 , 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. Dividend Reinvestment Plan The Company has a Dividend Reinvestment and Stock Purchase Plan (“DRIP”) under which holders of Common Stock may elect to automatically reinvest their dividends in additional shares of Common Stock and make optional cash payments for additional shares of Common Stock. Common Unit Distributions Distributions of the Operating Partnership declared and paid per Common Unit aggregated $1.70 for each of the years ended December 31, 2015 , 2014 and 2013 . 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. 12.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Employee Benefit Plans	Employee Benefit Plans Officer, Management and Director Compensation Programs The officers of the Company participate in an annual non-equity incentive program pursuant to which they are eligible to earn cash payments based on a percentage of their annual base salary in effect for December of the applicable year. Under this component of our executive compensation program, officers are eligible to earn additional cash compensation to the extent specific performance-based metrics are achieved during the most recently completed year. The position held by each officer has a target annual incentive percentage that ranges from 35% to 130% of base salary. The more senior the position, the greater the portion of compensation that varies with performance. The percentage amount an officer may earn under the annual non-equity incentive plan is the product of the target annual incentive percentage times an “actual performance factor,” which can range from zero to 200% . The actual performance factor depends upon the relationship between actual performance in specific areas at each of our divisions and predetermined goals. For corporate officers, the actual performance factor is based on the goals and criteria applied to the Company’s performance as a whole. For officers who oversee our divisions, the actual performance factor is based on the goals and criteria applied partly to that division’s performance and partly to the Company’s performance overall. Payments under our annual non-equity incentive plan are accrued and expensed in the year earned. Certain other employees participate in a similar annual non-equity incentive program. Incentive eligibility ranges from 6% to 30% of annual base salary. The actual incentive payment is determined by a mix of the Company's overall performance, the performance of any applicable division and the individual’s performance during each year. These incentive payments are also accrued and expensed in the year earned. 13. Employee Benefit Plans - Continued The Company's officers generally receive annual grants of stock options and restricted stock under the Company's long-term equity incentive plan on or about March 1 of each year. Restricted stock grants are also made annually to directors and certain other employees. Except as set forth in the next sentence, 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. 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 total return-based restricted stock may be issued at the end of the three-year periods if 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 three-year period since that possibility is reflected in the grant date fair value. The following table sets forth the number of shares of Common Stock reserved for future issuance under the Company's long-term equity incentive plans: December 31, 2015 2014 Outstanding stock options and warrants 702,228 592,321 Possible future issuance under equity incentive plans 3,084,158 1,382,406 3,786,386 1,974,727 Of the possible future issuance under the Company' long-term equity incentive plan at December 31, 2015 , no more than an additional 1.1 million shares can be in the form of restricted stock. During each of the years ended December 31, 2015 , 2014 and 2013 , we recognized $6.9 million of share-based compensation expense. Because REITs generally do not pay income taxes, we do not realize tax benefits on share-based payments. At December 31, 2015 , there was $4.9 million of total unrecognized share-based compensation costs, which will be recognized over a weighted average remaining contractual term of 2.3 years. - Stock Options Stock options issued prior to 2005 and after 2013 vest ratably on an annual basis over four years and expire after 10 years. Stock options issued from 2005 through 2013 vest ratably on an annual basis over four years and expire after seven years. The value of all options as of the date of grant is calculated using the Black-Scholes option-pricing model and is amortized over the respective vesting period or the service period, if shorter, for employees who are or will become eligible under the Company's retirement plan. The weighted average fair values of options granted during 2015 , 2014 and 2013 were $6.19 , $6.75 and $6.50 , respectively, per option. The fair values of the options granted were determined at the grant dates using the following assumptions: 2015 2014 2013 Risk free interest rate (1) 1.7 % 1.8 % 1.0 % Common stock dividend yield (2) 3.7 % 4.5 % 4.7 % Expected volatility (3) 22.4 % 30.3 % 32.4 % Average expected option life (years) (4) 5.75 5.75 5.75 __________ (1) Represents the interest rate as of the grant date on US treasury bonds having the same life as the estimated life of the option grants. (2) The dividend yield is calculated utilizing the dividends paid for the previous one -year period and the per share price of Common Stock on the date of grant. (3) Based on the historical volatility of Common Stock over a period relevant to the related stock option grant. (4) The average expected option life is based on an analysis of the Company's historical data. 13.

(2) The Company had 218,816 options exercisable at December 31, 2015 with a weighted average exercise price of $33.03 , weighted average remaining life of 3.2 years and intrinsic value of $2.3 million . Of these exercisable options, there were no exercise prices higher than the market price of our Common Stock at December 31, 2015 . Cash received or receivable from options exercised was $3.3 million , $11.1 million and $12.5 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. The total intrinsic value of options exercised during the years ended December 31, 2015 , 2014 and 2013 was $0.9 million , $5.0 million and $3.9 million , respectively. The total intrinsic value of options outstanding at December 31, 2015 , 2014 and 2013 was $4.3 million , $5.4 million and $4.3 million , respectively. The Company generally does not permit the net cash settlement of exercised stock options, but does permit net share settlement so long as the shares received are held for at least a year. The Company has a practice of issuing new shares to satisfy stock option exercises. - Time-Based Restricted Stock Shares of time-based restricted stock vest ratably on an annual basis over four years. The value of grants of time-based restricted stock is based on the market value of Common Stock as of the date of grant and is amortized to expense over the respective vesting period or the service period, if shorter, for employees who are or will become eligible under the Company's retirement plan. 13. Employee Benefit Plans - Continued The following table sets forth time-based restricted stock activity: Number of Shares Weighted Average Grant Date Fair Value Restricted shares outstanding at December 31, 2012 222,502 $ 30.31 Awarded and issued (1) 86,144 36.64 Vested (2) (94,037 ) 27.80 Forfeited (1,813 ) 36.01 Restricted shares outstanding at December 31, 2013 212,796 33.96 Awarded and issued (1) 94,932 37.76 Vested (2) (85,660 ) 32.87 Restricted shares outstanding at December 31, 2014 222,068 35.97 Awarded and issued (1) 71,994 45.91 Vested (2) (85,809 ) 35.14 Forfeited (3,533 ) 39.94 Restricted shares outstanding at December 31, 2015 204,720 $ 39.74 __________ (1) The weighted average fair value at grant date of time-based restricted stock issued during the years ended December 31, 2015 , 2014 and 2013 was $3.3 million , $3.6 million and $3.2 million , respectively. (2) The vesting date fair value of time-based restricted stock that vested during the years ended December 31, 2015 , 2014 and 2013 was $3.9 million , $3.2 million and $3.4 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% . Notwithstanding the Company’s absolute total returns, if the Company’s total return exceeds 100% of the peer group total return index, at least 50% of total return-based restricted stock issued in 2013 will vest at the end of the applicable period and at least 75% of total return-based restricted stock issued in 2015 and 2014 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 2015 , 2014 and 2013 was determined to be $43.77 , $35.58 and $31.73 , 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: 2015 2014 2013 Risk free interest rate (1) 1.0 % 0.7 % 0.4 % Common stock dividend yield (2) 3.8 % 4.7 % 4.9 % Expected volatility (3) 43.0 % 43.4 % 43.4 % __________ (1) Represents the interest rate as of the grant date on US treasury bonds having the same life as the estimated life of the total return-based restricted stock grants. (2) The dividend yield is calculated utilizing the dividends paid for the previous one -year period and the average per share price of Common Stock during the three-month period preceding the date of grant. (3) Based on the historical volatility of Common Stock over a period relevant to the related total return-based restricted stock grant. 13.

(2) The vesting date fair value of total return-based restricted stock that vested during the years ended December 31, 2015 and 2013 was $5.9 million and $1.5 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. There were no vested shares of total return-based restricted stock during the year ended December 31, 2014 . (3) The 2015 amounts include 61,860 additional shares from the 2012 plan since the plan's payout was in excess of the initial 100% target. 401(k) Retirement Savings Plan We have a 401(k) Retirement Savings Plan covering substantially all employees who meet certain age and employment criteria. We contribute amounts for each participant at a rate of 75% of the employee’s contribution (up to 6% of each employee’s bi-weekly salary and cash incentives, subject to statutory limits). During the years ended December 31, 2015 , 2014 and 2013 , we contributed $1.3 million , $1.2 million and $1.1 million , respectively, to the 401(k) savings plan. The assets of this qualified plan are not included in our Consolidated Financial Statements since the assets are not owned by us. Retirement Plan The Company has a retirement plan for employees with at least 30 years of continuous service or are at least 55 years old with at least 10 years of continuous service. Subject to advance written notice and a non-compete agreement, eligible retirees would be entitled to receive a pro rata amount of the annual non-equity incentive compensation earned during the year of retirement. 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. 13. Employee Benefit Plans - Continued 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 our non-qualified deferred compensation plan. These investments are recorded at fair value, which aggregated $2.7 million and $3.6 million at December 31, 2015 and 2014 , respectively, and are included in prepaid expenses and other assets, with an offsetting deferred compensation liability recorded in accounts payable, accrued expenses and other liabilities. Deferred amounts ultimately payable to the participants are based on the value of the related mutual fund investments. Accordingly, changes in the value of the unrelated mutual funds are recorded in interest and other income and the corresponding offsetting changes in the deferred compensation liability are recorded in general and administration expense. As a result, there is no effect on our net income. The following table sets forth our deferred compensation liability: Year Ended December 31, 2015 2014 2013 Beginning deferred compensation liability $ 3,635 $ 3,996 $ 3,354 Mark-to-market adjustment to deferred compensation (in general and administrative expenses) (32 ) 235 803 Distributions from deferred compensation plans (867 ) (596 ) (161 ) Total deferred compensation liability $ 2,736 $ 3,635 $ 3,996 Employee Stock Purchase Plan The Company has an Employee Stock Purchase Plan pursuant to which employees may contribute up to 25% of their cash compensation for the purchase of Common Stock. At the end of each quarterly offering period, each participant's account balance, which includes accumulated dividends, is applied to acquire shares of Common Stock at a cost that is calculated at 85% of the average closing price on the New York Stock Exchange on the five consecutive days preceding the last day of the quarter. In the years ended December 31, 2015 , 2014 and 2013 , the Company issued 29,496 , 28,682 and 27,250 shares, respectively, of Common Stock under this Plan. 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 in each of the years ended December 31, 2015 , 2014 and 2013 . As a general rule, shares purchased under the Plan must be held for at least a year.

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. As a REIT, the Company may also be subject to federal excise taxes if it engages in certain types of transactions. The minimum dividend per share of Common Stock required for the Company to maintain its REIT status was $1.31 , $1.13 and $1.08 per share in 2015 , 2014 and 2013 , respectively. Continued qualification as a REIT depends on the Company's ability to satisfy the dividend distribution tests, stock ownership requirements and various other qualification tests. The tax basis of the Company's assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $4.2 billion and $2.6 billion , respectively, at December 31, 2015 and $3.6 billion and $2.2 billion , respectively, at December 31, 2014 . The tax basis of the Operating Partnership's assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $4.2 billion and $2.6 billion , respectively, at December 31, 2015 and $3.6 billion and $2.2 billion , respectively, at December 31, 2014 . During the years ended December 31, 2015 , 2014 and 2013 , 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 following table sets forth the Company's income tax expense/(benefit): Year Ended December 31, 2015 2014 2013 Current tax expense: Federal $ 949 $ 1,480 $ 60 State 351 161 312 1,300 1,641 372 Deferred tax expense/(benefit): Federal (233 ) (1,628 ) 1,479 State (115 ) (305 ) 277 (348 ) (1,933 ) 1,756 Less tax expense netted against gain included in equity in earnings of unconsolidated affiliates — — (1,721 ) Less tax expense netted against gain on disposition of property (518 ) — — Total income tax expense/(benefit) $ 434 $ (292 ) $ 407 The Company's net deferred tax asset/(liability) is $(0.2) million and $0.1 million as of December 31, 2015 and 2014 , respectively. The net deferred tax asset/(liability) is comprised primarily of tax versus book differences related to property (depreciation, amortization and basis differences). For the years ended December 31, 2015 and 2014 , there were no unrecognized tax benefits. The Company is subject to federal, state and local income tax examinations by taxing authorities for 2012 through 2015 .

Segment Reporting [Abstract]
Segment Information	Segment Information Our principal business is the operation, acquisition and development of rental real estate properties. We evaluate our business by product type and by geographic location. Each product type has different customers and economic characteristics as to rental rates and terms, cost per rentable square foot of buildings, the purposes for which customers use the space, the degree of maintenance and customer support required and customer dependency on different economic drivers, among others. The operating results by geographic grouping are also regularly reviewed by our chief operating decision maker for assessing performance and other purposes. There are no material inter-segment transactions. Our accounting policies of the segments are the same as those used in our Consolidated Financial Statements. All operations are within the United States. The following tables summarize the rental and other revenues and net operating income, the primary industry property-level performance metric used by our chief operating decision maker which is defined as rental and other revenues less rental property and other expenses, for each of our reportable segments. Our segment information for the years ended December 31, 2014 and 2013 have been retrospectively revised from previously reported amounts to reflect a change in our reportable segments.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events We entered into an agreement, dated as of January 29, 2016, to sell a 32,000 square foot building for $4.7 million. The buyer, which currently leases 79% of the building, is a family business controlled by a director of the Company. The sale price exceeds the value set forth in an appraisal performed by a reputable commercial real estate services firm that has no relationship with the director or any of his affiliates. We expect to record a gain of approximately $1.0 million upon completion of the sale, which is expected to close in the second quarter of 2016. On January 4, 2016, we announced our agreement to sell the Plaza assets in Kansas City for $660.0 million. The buyer is Country Club Plaza KC Partners LLC, a joint venture between affiliates of Taubman Centers, Inc. (NYSE:TCO) and The Macerich Company (NYSE:MAC). The Plaza assets consist of 18 properties encompassing 776,000 square feet of in-service retail space, 468,000 square feet of in-service office space and a 28,000 square foot retail redevelopment project. The parties have entered into a series of definitive agreements, dated as of December 21, 2015, relating to the sale of the Plaza assets. The sales, which are subject to customary closing conditions, are scheduled to close on March 1, 2016. The buyer’s contractual due diligence investigation period ended on December 31, 2015. The buyer has posted earnest money deposits, held by a third party, totaling $25.0 million that are non-refundable and the buyer would be obligated to pay us an additional $25.0 million in the event of a default, except in limited circumstances.

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”). Our Consolidated Balance Sheets at December 31, 2014 were retrospectively revised from previously reported amounts to reclassify those properties classified as held for sale as of December 31, 2015 . Our Consolidated Statements of Income for the years ended December 31, 2014 and 2013 were retrospectively revised from previously reported amounts to reclassify the operations for those properties classified as discontinued operations. 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 partnerships, joint ventures and limited liability companies when we control the major operating and financial policies of the entity through majority ownership or in our capacity as general partner or managing member. At December 31, 2015 , three of the 50.0% or less owned in-service office properties in a joint venture were consolidated. In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. During 2015 , we acquired three buildings and a land parcel using special purpose entities owned by qualified intermediaries to facilitate a potential Section 1031 reverse exchange under the Internal Revenue Code. To realize the tax deferral available under the Section 1031 exchange, we must complete the Section 1031 exchange, and take title to the to-be-exchanged buildings within 180 days of the acquisition date. We have determined that these entities are variable interest entities of which we are the primary beneficiary; and therefore, we consolidate these entities. As of December 31, 2015 , these variable interest entities had total assets, liabilities and cash flows of $421.3 million , $16.3 million , and $7.1 million , respectively. At December 31, 2014 , we had involvement with, but were not the primary beneficiary in, an entity that we concluded to be a variable interest entity. 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.
Real Estate and Related Assets	Real Estate and Related Assets Real estate and related assets are recorded at cost and stated at cost less accumulated depreciation. Renovations, replacements and other expenditures that improve or extend the life of assets are capitalized and depreciated over their estimated useful lives. Expenditures for ordinary maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful life of 40 years for buildings and depreciable land infrastructure costs, 15 years for building improvements and five to seven years for furniture, fixtures and equipment. Tenant improvements are amortized using the straight-line method over initial fixed terms of the respective leases, which generally are from three to 10 years. Depreciation expense for real estate assets was $ 168.7 million , $ 154.4 million and $ 138.2 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and are stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction. 1. Description of Business and Significant Accounting Policies – Continued Expenditures directly related to the leasing of properties are included in deferred financing and leasing costs and are stated at amortized cost. Such expenditures are part of the investment necessary to execute leases and, therefore, are classified as investment activities in the statement of cash flows. All leasing commissions paid to third parties for new leases or lease renewals are capitalized. Internal leasing costs, which consist primarily of compensation, benefits and other costs, such as legal fees related to leasing activities, that are incurred in connection with successfully obtaining leases of properties are also capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases, which generally are from three to 10 years. Estimated costs related to unsuccessful activities are expensed as incurred. We record liabilities for the performance of asset retirement activities when the obligation to perform such activities is probable even when uncertainty exists about the timing and/or method of settlement. Upon the acquisition of real estate assets, we assess the fair value of acquired tangible assets such as land, buildings and tenant improvements, intangible assets and liabilities such as above and below market leases, acquired in-place leases, customer relationships and other identifiable intangible assets and assumed liabilities. We assess fair value based on estimated cash flow projections that utilize discount and/or capitalization rates as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. The above and below market rate portions of leases acquired in connection with property acquisitions are recorded in deferred financing and 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 financing and leasing costs and are amortized to depreciation and amortization expense over the remaining term of the respective lease. The value of in-place leases is based on our evaluation of the specific characteristics of each customer's lease. Factors considered include estimates of carrying costs during hypothetical expected lease-up periods, current market conditions, the customer's credit quality and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider tenant improvements, leasing commissions and legal and other related expenses. Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the sale of the asset is probable, has been duly approved by the Company, a legally enforceable contract has been executed and the buyer's due diligence period, if any, has expired.
Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates	Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates With respect to assets classified as held for use, we perform an impairment analysis if events or changes in circumstances indicate that the carrying value may be impaired, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset's carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete. 1. Description of Business and Significant Accounting Policies – Continued If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and are subject to future events that may alter our assumptions, the discounted and/or undiscounted future operating and residual cash flows estimated by us in our impairment analyses or those established by appraisal may not be achieved and we may be required to recognize future impairment losses on properties held for use. We record assets held for sale at the lower of the carrying amount or estimated fair value. Fair value of assets held for sale is equal to the estimated or contracted sales price with a potential buyer, less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value. We also analyze our investments in unconsolidated affiliates for impairment. This analysis consists of determining whether an expected loss in market value of an investment is other than temporary by evaluating the length of time and the extent to which the market value has been less than cost, the financial condition and near-term prospects of the unconsolidated affiliate, and our intent and ability to retain our investment for a period of time sufficient to allow for any anticipated recovery in market value. As the factors used in this analysis are difficult to predict and are subject to future events that may alter our assumptions, we may be required to recognize future impairment losses on our investments in unconsolidated affiliates.
Sales of Real Estate	Sales of Real Estate For sales transactions meeting the requirements for full profit recognition, 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. For sales transactions with continuing involvement after the sale, if the continuing involvement with the property is limited by the terms of the sales contract, profit is recognized at the time of sale and is reduced by the maximum exposure to loss related to the nature of the continuing involvement. Sales to entities in which we have or receive an interest are accounted for using partial sale accounting. For transactions that do not meet the criteria for a sale, we evaluate the nature of the continuing involvement, including put and call provisions, if present, and account for the transaction as a financing arrangement, profit-sharing arrangement, leasing arrangement or other alternate method of accounting, rather than as a sale, based on the nature and extent of the continuing involvement. Some transactions may have numerous forms of continuing involvement. In those cases, we determine which method is most appropriate based on the substance of the transaction.
Rental and Other Revenues	Rental and Other Revenues Minimum contractual rents from leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Contingent rental revenue, such as percentage rent, is accrued when the contingency is removed. Termination fee income is recognized at the later of when the customer has vacated the space or the lease has expired and a fully executed lease termination agreement has been delivered, the amount of the fee is determinable and collectability of the fee is reasonably assured. Rental revenue reductions related to co-tenancy lease provisions, if any, are accrued when events have occurred that trigger such provisions. 1. Description of Business and Significant Accounting Policies – Continued Cost recovery income is determined on a calendar year and a lease-by-lease basis. The most common types of cost recovery income in our leases are common area maintenance (“CAM”) and real estate taxes, for which a customer typically pays its pro-rata share of operating and administrative expenses and real estate taxes in excess of the costs incurred during a contractually specified base year. The computation of cost recovery income is complex and involves numerous judgments, including the interpretation of lease provisions. Leases are not uniform in dealing with such cost recovery income and there are many variations in the computation. Many customers make monthly fixed payments of CAM, real estate taxes and other cost reimbursement items. We accrue income related to these payments each month. We make quarterly accrual adjustments, positive or negative, to cost recovery income to adjust the recorded amounts to our best estimate of the final annual amounts to be billed and collected. After the end of the calendar year, we compute each customer's final cost recovery income and, after considering amounts paid by the customer during the year, issue a bill or credit for the appropriate amount to the customer. The differences between the amounts billed less previously received payments and the accrual adjustment are recorded as increases or decreases to cost recovery income when the final bills are prepared, which occurs during the first half of the subsequent year.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts Accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable are reduced by an allowance for amounts that may become uncollectible in the future. We regularly evaluate the adequacy of our allowance for doubtful accounts. The evaluation primarily consists of reviewing past due account balances and considering such factors as the credit quality of our customer, historical trends of the customer and changes in customer payment terms. Additionally, with respect to customers in bankruptcy, we estimate the probable recovery through bankruptcy claims and adjust the allowance for amounts deemed uncollectible. If our assumptions regarding the collectability of receivables prove incorrect, we could experience losses in excess of our allowance for doubtful accounts. The allowance and its related receivable are written-off when we have concluded there is a low probability of collection and we have discontinued collection efforts.
Discontinued Operations	Discontinued Operations Subsequent to the early adoption of the Financial Accounting Standards Board ("FASB") accounting standards update on the presentation of discontinued operations beginning in April 2014, 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. If the property is sold to a joint venture in which we retain an interest, the property will not be accounted for as a discontinued operation due to our significant ongoing interest in the operations through our joint venture interest. If we are retained to provide property management, leasing and/or other services for the property owner after the sale, the property generally will be accounted for as a discontinued operation because the expected cash flows related to our management and leasing activities generally will not be significant in comparison to the cash flows from the property prior to sale.
Lease Incentives	Lease Incentives Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign a lease, are capitalized in deferred financing and leasing costs and amortized on a straight-line basis over the respective lease terms as a reduction of rental revenues.
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates We account for our investments in less than majority owned joint ventures, partnerships and limited liability companies 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 entity. These investments are initially recorded at cost in 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 and Cash Equivalent	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, escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements and any deposits made with lenders to unencumber secured properties.
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 temporary differences between such income and the amount recognized for tax purposes.
Concentration of Credit Risk	Concentration of Credit Risk At December 31, 2015 , properties that we wholly own were leased to 1,910 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Raleigh, NC, Atlanta, GA, Tampa, FL and Nashville, TN. Our customers engage in a wide variety of businesses. No single customer of the properties that we wholly own generated more than 6.0% of our consolidated revenues during 2015 . 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, bridge facility and bank term loans bear interest at variable rates. Our long-term debt typically bears interest at fixed rates. Our interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and to lower our overall borrowing costs. To achieve these objectives, from time to time, we enter into interest rate hedge contracts such as collars, swaps, caps and treasury lock agreements in order to mitigate our interest rate risk with respect to various debt instruments. We generally do not hold or issue these derivative contracts for trading or speculative purposes. The interest rate on all of our variable rate debt is generally adjusted at one or three month intervals, subject to settlements under these interest rate hedge contracts. Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive loss ("AOCL") and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings. We account for terminated derivative instruments by recognizing the related accumulated comprehensive income/loss balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated comprehensive income/loss into earnings over the originally designated hedge period.
Earnings Per Share	Earnings Per Share and Per Unit Basic earnings per share of the Company is computed by dividing net income available for common stockholders by the weighted Common Shares outstanding - basic. Diluted earnings per share is computed by dividing net income available to common stockholders plus noncontrolling interests in the Operating Partnership by the weighted Common Shares outstanding - basic plus the dilutive effect of options, warrants and convertible securities outstanding, including Common Units, using the treasury stock method. Weighted Common Shares outstanding - basic includes all unvested restricted stock where dividends received on such restricted stock are non-forfeitable. Basic earnings per unit of the Operating Partnership is computed by dividing net income available for common unitholders by the weighted Common Units outstanding - basic. Diluted earnings per unit is computed by dividing net income available to common unitholders by the weighted Common Units outstanding - basic plus the dilutive effect of options and warrants, using the treasury stock method. Weighted Common Units outstanding - basic includes all of the Company's unvested restricted stock where dividends received on such restricted stock are non-forfeitable.
Recently Issued Accounting Standards	Recently Issued Accounting Standards The FASB recently issued an accounting standards update that requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The accounting standards update is required to be adopted in 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. We are in the process of evaluating this accounting standards update. The FASB recently issued an accounting standards update that amends consolidation requirements. The amendments significantly change the consolidation analysis required under GAAP and will require companies to reevaluate all previous consolidation conclusions. The accounting standards update is required to be adopted in 2016. We are in the process of evaluating this accounting standards update. The FASB recently issued an accounting standards update that requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The accounting standards update is required to be adopted in 2016. Retrospective application is required. We do not expect such adoption to have a material effect on the balance sheet.
