	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, 2013, we owned or had an interest in 32.2 million rentable square feet of in-service office, industrial and retail properties, 0.9 million rentable square feet of office properties under development and approximately 600 acres of development land.
	The Company is the sole general partner of the Operating Partnership. At December 31, 2013, the Company owned all of the Preferred Units and 89.5 million, or 96.8%, of the Common Units in the Operating Partnership. Limited partners own 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 2013, the Company redeemed 789,144 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 95.6% at December 31, 2012 to 96.8% at December 31, 2013.
	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, 2012 were retrospectively revised from previously reported amounts to reflect in real estate and other assets, net, held for sale those properties classified as held for sale during 2013. Our Consolidated Statements of Income for the years ended December 31, 2012 and 2011 were retrospectively revised from previously reported amounts to reflect in discontinued operations 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. Five of the 50.0% or less owned in-service office properties in two joint ventures are consolidated. In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. At December 31, 2013 and 2012, we had involvement with, but are not the primary beneficiary in, an entity that we concluded to be a variable interest entity (see Note 3). All intercompany transactions and accounts have been eliminated.
	Use of Estimates
	The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
	1.    Description of Business and Significant Accounting Policies – Continued
	Real Estate and Related Assets
	Real estate and related assets are recorded at cost and stated at cost less accumulated depreciation. Renovations, replacements and other expenditures that improve or extend the life of assets are capitalized and depreciated over their estimated useful lives. Expenditures for ordinary maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful life of 40 years for buildings and depreciable land infrastructure costs, 15 years for building improvements and five to seven years for furniture, fixtures and equipment. Tenant improvements are amortized using the straight-line method over initial fixed terms of the respective leases, which generally are from three to 10 years. Depreciation expense for real estate assets was $138.2 million, $118.2 million and $106.8 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and are stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction.
	Expenditures directly related to the leasing of properties are included in deferred 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 include primarily compensation, benefits and other costs, such as legal fees related to leasing activities, that are incurred in connection with successfully obtaining leases of properties. 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.
	1.    Description of Business and Significant Accounting Policies – Continued
	Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the sale of the asset has been duly approved by the Company, a legally enforceable contract has been executed and the buyer's due diligence period has expired.
	Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates
	With respect to assets classified as held for use, we perform an impairment analysis if events or changes in circumstances indicate that the carrying value may be impaired, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset's carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete.
	If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and are subject to future events that may alter our assumptions, the discounted and/or undiscounted future operating and residual cash flows estimated by us in our impairment analyses or those established by appraisal may not be achieved and we may be required to recognize future impairment losses on properties held for use.
	We record assets held for sale at the lower of the carrying amount or estimated fair value. Fair value of assets held for sale is equal to the estimated or contracted sales price with a potential buyer, less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value.
	We also analyze our investments in unconsolidated affiliates for impairment. This analysis consists of determining whether an expected loss in market value of an investment is other than temporary by evaluating the length of time and the extent to which the market value has been less than cost, the financial condition and near-term prospects of the investee, 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.
	1.    Description of Business and Significant Accounting Policies – Continued
	Rental and Other Revenues
	Minimum contractual rents from leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Contingent rental revenue, such as percentage rent, is accrued when the contingency is removed. Termination fee income is recognized at the later of when the customer has vacated the space or the lease has expired and a fully executed lease termination agreement has been delivered, the amount of the fee is determinable and collectability of the fee is reasonably assured. Rental revenue reductions related to co-tenancy lease provisions, if any, are accrued when events have occurred that trigger such provisions.
	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 the customer 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 terms and other customer lease provisions. Leases are not uniform in dealing with such cost recovery income and there are many variations in the computation. Many customers make monthly fixed payments of CAM, real estate taxes and other cost reimbursement items. We accrue income related to these payments each month. We make quarterly accrual adjustments, positive or negative, to cost recovery income to adjust the recorded amounts to our best estimate of the final annual amounts to be billed and collected. After the end of the calendar year, we compute each customer's final cost recovery income and, after considering amounts paid by the customer during the year, issue a bill or credit for the appropriate amount to the customer. The differences between the amounts billed less previously received payments and the accrual adjustment are recorded as increases or decreases to cost recovery income when the final bills are prepared, which occurs during the first half of the subsequent year.
	Allowance for Doubtful Accounts
	Accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable are reduced by an allowance for amounts that may become uncollectible in the future. We regularly evaluate the adequacy of our allowance for doubtful accounts. The evaluation primarily consists of reviewing past due account balances and considering such factors as the credit quality of our customer, historical trends of the customer and changes in customer payment terms. Additionally, with respect to customers in bankruptcy, we estimate the probable recovery through bankruptcy claims and adjust the allowance for amounts deemed uncollectible. If our assumptions regarding the collectability of receivables prove incorrect, we could experience losses in excess of our allowance for doubtful accounts. The allowance and its related receivable are written-off when we have concluded there is a low probability of collection and we have discontinued collection efforts.
	Discontinued Operations
	Properties that are sold or classified as held for sale are classified as discontinued operations provided that (1) the operations and cash flows of the property will be eliminated from our ongoing operations and (2) we will not have any significant continuing involvement in the operations of the property after it is sold. Interest expense is included in discontinued operations if the related loan securing the sold property is to be paid off or assumed by the buyer in connection with the sale. 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. If the property is contributed 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.
	1.    Description of Business and Significant Accounting Policies – Continued
	Lease Incentives
	Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign the 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.
	For-Sale Residential Condominiums
	For-sale residential condominiums include completed, but unsold, condominium inventory. We initially record receipts of earnest money deposits in accounts payable, accrued expenses and other liabilities in accordance with the deposit method. We then record completed sales when units close and the remaining net cash is received. All for-sale residential condominiums were sold as of December 31, 2012.
	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 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.
	1.    Description of Business and Significant Accounting Policies – Continued
	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, 2013, properties that we wholly own were leased to 1,793 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Raleigh, NC, Atlanta, GA, Tampa, FL, Nashville, TN and Pittsburgh, PA. Our customers engage in a wide variety of businesses. No single customer of the properties that we wholly own generated more than 10.0% of our consolidated revenues during 2013.
	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 subjects our balance to the credit risk of the institution.
	Derivative Financial Instruments
	We borrow funds at a combination of fixed and variable rates. Borrowings under our revolving credit facility and bank term loans bear interest at variable rates. Our long-term debt typically bears interest at fixed rates. Our interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and 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.

	Acquisitions
	During 2013, we acquired:
	•	our joint venture partner's 60.0% interest in our HIW-KC Orlando, LLC joint venture, which owned five office properties 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 matures in July 2014. 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;
	•	an office property in Nashville, TN encompassing 520,000 rentable square feet for a net purchase price of $150.1 million;

During 2011, we recorded impairments of real estate assets of $2.4 million on two office properties in Orlando, FL. 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.

	Mortgages and notes receivable, net	$	26,409		$	25,472
	During 2010, we provided seller financing in conjunction with two disposition transactions. The seller financing is evidenced by first mortgages secured by the assignment of rents and the underlying real estate assets.
	During 2012, we provided an $8.6 million loan to a third party, which was used by such third party to fund a portion of the purchase price to acquire 77 acres of mixed-use development land adjacent to our 68-acre office development parcel in Nashville, TN. Initially, the loan is scheduled to mature in December 2015 and bears interest at 5.0% per year. The loan can be extended by the third party for up to three additional years, subject to applicable increases in the interest rate. We also agreed to loan such third party $8.4 million on a secured basis to fund future infrastructure development securitized by the 77 acres. As of December 31, 2013, $0.3 million has been funded to the third party for infrastructure development. We concluded this arrangement to be an interest in a variable interest entity. However, since we do not have the power to direct matters that most significantly impact the activities of the entity, we do not qualify as the primary beneficiary. Accordingly, the entity is not consolidated. Our risk of loss with respect to this arrangement is limited to the carrying value of the mortgage receivable and the future infrastructure development funding commitment.
	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, 2013, our mortgages and notes receivable were not in default and there were no other indicators of impairment.
	The following table sets forth our notes receivable allowance, which relates only to promissory notes:

The following summarizes additional information related to certain of our unconsolidated affiliates:
- 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.
- Lofts at Weston, LLC ("Weston Lofts")
During 2011, we and Ravin Partners, LLC (“Ravin”) formed Weston Lofts, in which we have 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 manages and operates this joint venture, which constructed 215 residential units at a total cost of $25.9 million. Ravin was the developer, manager and leasing agent and received customary fees from the joint venture. 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”)
See Note 2 for a description of our acquisition of two office properties in Atlanta, GA from DLF II during 2013.
During 2013, DLF II sold an office property 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.
During 2012, DLF II obtained a $50.0 million, three-year secured mortgage loan from a third party lender, bearing a fixed interest rate of 3.5% on $39.1 million of the loan and a floating interest rate of LIBOR plus 250 basis points on $10.9 million of the loan, which was used by the joint venture to repay a secured loan at maturity to a third party lender. During 2013, this loan was assumed by us in connection with the acquisition discussed in Note 2.
- Kessinger/Hunter, LLC
Kessinger/Hunter, LLC, which is managed by our joint venture partner, provides leasing services, among other things, to certain office properties that we wholly own in Kansas City, MO in exchange for customary fees from us. Kessinger/Hunter, LLC received $0.2 million, $1.1 million and $2.1 million from us for these services in 2013, 2012 and 2011, 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”)
At the formation of this joint venture in 1999, our partner contributed excess cash to the venture that was distributed to us under the joint venture agreements. We are required to repay this excess cash to our partner over time, as discussed in Note 9.
During 2013, DLF I sold an office property 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 office properties 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.
During 2012, DLF I sold two office properties to third parties for $15.5 million and recorded gains on disposition of property of $4.9 million. We recorded $1.1 million as our proportionate share of these gains through equity in earnings of unconsolidated affiliates.
During 2012, we recorded $1.0 million as our share of impairments of real estate assets on two office properties in DLF I, due to a decline in projected occupancy and a change in the assumed holding period of those assets, which reduced the expected future cash flows from the properties.
During 2011, we provided a $38.3 million interest-only secured loan to DLF I that was initially scheduled to mature in March 2012. During 2012, the outstanding balance of the loan was repaid as a result of our acquisition of an office property from the joint venture and through application of the net proceeds from the joint venture's sale of two office properties to third parties as noted above. We recorded $0.9 million and $1.3 million of interest income from this loan in interest and other income during the years ended December 31, 2012 and 2011, respectively.

During 2011, our joint venture partner exercised its option to acquire our 10.0% equity interest in the HIW Development B, LLC joint venture, which had recently completed construction of a build-to-suit office property in Charlotte, NC. As a result, we received gross proceeds of $4.8 million and recorded a gain on disposition of investment in unconsolidated affiliate related to this merchant build project of $2.3 million.
- 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, 2013, 2012 and 2011, we recognized $2.9 million, $2.4 million and $3.1 million, respectively, of development, management and leasing fees from our unconsolidated joint ventures. At December 31, 2013 and 2012, we had receivables of $0.5 million and $0.9 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 general partner and control the major operating and financial policies of the joint venture. As controlling partner, we have an obligation to cause this property-owning entity to distribute proceeds of liquidation to the noncontrolling interest partner 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 $33.4 million had the entity been liquidated at December 31, 2013. 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.
4.    Investments in and Advances to Affiliates – Continued
- SF-HIW Harborview Plaza, LP (“Harborview”)
We have a 20.0% interest in Harborview. We are the manager and leasing agent for Harborview's property in Tampa, FL and receive customary management and leasing fees. As further described in Note 8, we account for this joint venture as a financing obligation since our partner has the right to put its 80.0% equity interest back to us during the one-year period commencing September 11, 2014.
During 2012, we provided a three-year, $20.8 million interest-only secured loan to Harborview that is scheduled to mature in September 2015, which the joint venture used to repay a secured loan at maturity to a third party lender. This new loan bears interest at LIBOR plus 500 basis points, subject to a LIBOR floor of 0.5%. Because Harborview is a consolidated joint venture, this loan and related interest income and expense are eliminated in consolidatio

	During 2013, we entered into an amended and restated $475.0 million unsecured revolving credit facility, which replaced our previously existing revolving credit facility, and includes an accordion feature that allows for an additional $75.0 million of borrowing capacity subject to additional lender commitments. Our new revolving credit facility is scheduled to mature in January 2018. Assuming no defaults have occurred, we have an option to extend the maturity for two additional six-month periods. The interest rate on the new facility at our current credit ratings is LIBOR plus 110 basis points and the annual facility fee is 20 basis points. The interest rate and facility fee are based on the higher of the publicly announced ratings from Moody's Investors Service or Standard & Poor's Ratings Services. The financial and other covenants under the new facility are similar to our previous credit facility. There was $215.7 million and $223.0 million outstanding under our revolving credit facility at December 31, 2013 and January 31, 2014, respectively. At both December 31, 2013 and January 31, 2014, we had $0.1 million of outstanding letters of credit, which reduces the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility at December 31, 2013 and January 31, 2014 was $259.2 million and $251.9 million, respectively. We simultaneously amended and restated our $200.0 million, five-year unsecured bank term loan which, from a previous modification, was scheduled to mature in January 2018. The loan is now scheduled to mature in January 2019 and the interest rate, based on our current credit ratings, was reduced to LIBOR plus 120 basis points. We incurred $0.4 million of deferred financing fees in connection with the recent modification, which will be amortized along with existing unamortized deferred loan fees over the remaining term of the new loan.
	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. Real estate assets having a gross book value of approximately $147 million became unencumbered in connection with the payoff of these secured loans. We also paid down $11.7 million of secured loan balances through principal amortization during 2013.
	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.
	During 2012, we repaid the remaining balances of $52.1 million of our variable rate, secured construction loan bearing interest of 1.07% and a $123.0 million secured mortgage loan bearing interest of 6.03% that was scheduled to mature in March 2013. One of our consolidated affiliates also repaid a $20.8 million secured loan that bore interest at 6.06% and matured in October 2012. We incurred no penalties related to these repayments.
	6.    Mortgages and Notes Payable - Continued
	During 2012, the Operating Partnership issued $250.0 million aggregate principal amount of 3.625% Notes due January 15, 2023, less original issue discount of $2.7 million. These notes were priced at 98.94% for an effective yield of 3.752%. Underwriting fees and other expenses were incurred that aggregated $2.1 million; these costs were deferred and will be amortized over the term of the notes.
	During 2012, we modified our $200.0 million, five-year unsecured bank term loan, as discussed above, whereby the original maturity date of February 2016 was extended to January 2018 and the original interest rate was reduced from LIBOR plus 220 basis points to LIBOR plus 165 basis points. We incurred $0.9 million of deferred financing fees in connection with this previous modification, which was amortized along with existing unamortized deferred loan fees over the remaining term of the loan. Proceeds from two new participants, aggregating $35.0 million, were used to reduce amounts outstanding under our revolving credit facility. Two of the original participants, which held an aggregate $35.0 million of the principal balance under the original term loan, were fully paid off in February 2013.
	During 2012, we repurchased $12.1 million principal amount of unsecured notes due March 2017 bearing interest of 5.85% for a purchase price of 107.5% of par value. We recorded $1.0 million of loss on debt extinguishment related to this repurchase.
	During 2012, we obtained a $225.0 million, seven-year unsecured bank term loan bearing interest of LIBOR plus 190 basis points. The underlying LIBOR rate has been effectively fixed for the entire seven-year term through floating-to-fixed interest rate swaps discussed in Note 7. The counterparties under the swaps are the same financial institutions that participated in the term loan.
	During 2011, we repaid the remaining balance of $184.2 million of a secured mortgage loan bearing interest of 7.05% that was scheduled to mature in January 2012 and the remaining $10.0 million of a three-year unsecured term loan bearing interest of 3.90% that was scheduled to mature in February 2012. We incurred no penalties related to these early repayments. We also obtained a $200.0 million, five-year unsecured bank term loan bearing interest of LIBOR plus 220 basis points; this loan has been modified as described above.
	We are currently in compliance with financial covenants and other requirements with respect to our consolidated debt.
	Our revolving credit facility and bank term loans require us to comply with customary operating covenants and various financial requirements. Upon an event of default on the revolving credit facility, the lenders having at least 51.0% of the total commitments under the revolving credit facility can accelerate all borrowings then outstanding, and we could be prohibited from borrowing any further amounts under our revolving credit facility, which would adversely affect our ability to fund our operations.
	The Operating Partnership has $379.3 million carrying amount of 2017 bonds outstanding, $200.0 million carrying amount of 2018 bonds outstanding and $247.6 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 $2.7 million, $1.0 million and $0.6 million for the years ended December 31, 2013, 2012 and 2011, respectively.

	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 defaults 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 derivative obligations. These swaps have been designated as and are being accounted for as cash flow hedges with changes in fair value recorded in other comprehensive income 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, 2013. 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 2014, we estimate that $3.3 million will be reclassified to interest expense.

	Harborview
	In 2002, we contributed Harborview Plaza, a 205,000 rentable square foot office building to our Harborview joint venture. We retained a 20.0% equity interest in the joint venture. Our joint venture partner has the right to put its 80.0% equity interest in the joint venture to us in exchange for cash at any time during the one-year period commencing September 11, 2014. The value of the 80.0% equity interest will be determined at the time that our partner elects to exercise its put right, if ever, based upon the then fair market value of the joint venture's assets and liabilities. The fair value of the real estate assets will be reduced by 3.0%, which is intended to represent the hypothetical costs of a sale transaction. Because of the put option, this transaction has been accounted for as a financing transaction. Accordingly, the assets, liabilities and operations of Harborview Plaza, which is the sole property owned by Harborview, remain in our Consolidated Financial Statements.
	As a result, we initially established a gross financing obligation equal to the $12.7 million equity contributed by our joint venture partner. During 2012, our joint venture partner contributed an additional $1.8 million of equity to the joint venture. During each period, we increase the gross financing obligation for 80.0% of the net income before depreciation of Harborview Plaza, which is recorded as interest expense on financing obligation, and decrease the gross financing obligation for distributions made to our joint venture partner. At the end of each reporting period, the balance of the gross financing obligation is adjusted to equal the greater of the equity contributed by our joint venture partner or the current fair value of the put option, which is recorded as a valuation allowance. The valuation allowance is amortized on a straight-line basis prospectively through September 2014 as interest expense on financing obligation. The fair value of the put option was $12.8 million and $12.7 million at December 31, 2013 and 2012, respectively. We continue to depreciate Harborview Plaza and record all of the depreciation on our books. At such time as the put option expires or is otherwise terminated, we will record the transaction as a partial sale and recognize gain accordingly.
	Tax Increment Financing Bond
	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. 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, which is recorded in prepaid and other assets, in a privately negotiated transaction in 2007. For additional information about this tax increment financing bond, see Note 11.

	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 $2.8 million, $1.5 million and $1.4 million for the years ended December 31, 2013, 2012 and 2011, respectively.

	Lease and Contractual Commitments
	We have $233.8 million of lease and contractual commitments at December 31, 2013. 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 $25.9 million was recorded on the Consolidated Balance Sheet at December 31, 2013.
	DLF I Obligation
	At the formation of DLF I, the amount our partner contributed in cash to the venture and subsequently distributed to us was determined to be $7.2 million in excess of the amount required based on its ownership interest and the agreed-upon value of the real estate assets. We were required to repay this amount over 14 years, beginning in the first quarter of 1999. The $7.2 million was discounted to net present value of $3.8 million using a discount rate of 9.62% specified in the agreement. Payments of $0.2 million, $0.6 million and $0.6 million were made in the years ended December 31, 2013, 2012 and 2011, respectively. The balance at December 31, 2012 was $0.2 million, which was included in accounts payable, accrued expenses and other liabilities. During 2013, the obligation was fully paid.
	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 Interests
	Noncontrolling Interests in Consolidated Affiliates
	At December 31, 2013, our noncontrolling interests in consolidated affiliates relates 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:

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 assets are investments in marketable securities that we use to pay benefits under our non-qualified deferred compensation plan. Our Level 1 liability is our non-qualified deferred compensation obligation. The Company's Level 1 noncontrolling interests in the Operating Partnership relate to the ownership of Common Units by various individuals and entities other than the Company.
	Level 2. Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.
	Our Level 2 assets include the fair value of certain of our mortgages and notes receivable and certain of our interest rate swaps. Our Level 2 liabilities include the fair value of our mortgages and notes payable and the remainder of our 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 incorporated 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, (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, and (3) any real estate assets recorded at fair value on a non-recurring basis as a result of our quarterly impairment analysis, which were valued using the terms of definitive sales contracts or the sales comparison approach and substantiated with internal cash flow projections.
	Our Level 3 liabilities include the fair value of our contingent consideration to acquire real estate assets and financing obligations, which were 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.

	Ending balance	$	—		$	563
	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, 2013 was $1.0 million below 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 $0.5 million lower or $0.5 million higher, respectively, as of December 31, 2013. We intend to hold this bond and have concluded that we will not be required to sell this bond before recovery of the bond principal. 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, 2013 and 2012. There is no legal right of offset with the liability, which we report as a financing obligation, related to this tax increment financing bond.
During 2013, we recorded impairment charges on certain real estate assets, which were subsequently sold during the year, based upon aggregate fair values at the time of impairment of $14.9 million. These impaired real estate assets were deemed to be Level 3 assets and valued based primarily on market-based inputs and our assumptions about the use of the assets, as observable inputs were not available. In the absence of observable inputs, we estimate the fair value of real estate using unobservable 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 are recorded at fair value on our Consolidated Balance Sheets :
	Valuation		Unobservable	Rate/ Percentage
	Technique		Input
Assets:
Tax increment financing bond	Income approach		Discount rate	9.30%
Impaired real estate assets	Income approach		Capitalization rate	8.5%-10.5%

	Warrants
	At December 31, 2013 and 2012, 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. The Company may elect to satisfy DRIP obligations by issuing additional shares of Common Stock or instructing the DRIP administrator to purchase Common Stock in the open market.
	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, 2013, 2012 and 2011.
	Redeemable Common Units
	Generally, the Operating Partnership is obligated to redeem each Redeemable Common Unit at the request of the holder thereof for cash equal to the value of one share of Common Stock based on the average of the market price for the 10 trading days immediately preceding the notice date of such redemption, provided that the Company at its option may elect to acquire any such Redeemable Common Unit presented for redemption for cash or one share of Common Stock. When a holder redeems a Redeemable Common Unit for a share of Common Stock or cash, the Company’s share in the Operating Partnership will be increased. The Common Units owned by the Company are not redeemable.

	Employee Benefit Plans
	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 30% to 130% of base salary. The more senior the position within the Company, 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 an officer who has division responsibilities, goals for certain performance criteria are based partly on the division’s actual performance relative to that division’s established goals and partly on actual total performance. 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 10% to 30% of annual base salary. The actual incentive payment is determined by our overall performance 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 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 restricted stock issued to the Company's chief executive officer in 2012 and 2013, 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:
		December 31,
		2013			2012
	Outstanding stock options and warrants	889,382			1,144,309
	Possible future issuance under equity incentive plans	1,742,237			2,047,550
		2,631,619			3,191,859
	Of the possible future issuance under equity incentive plans at December 31, 2013, no more than 0.4 million can be in the form of restricted stock. At December 31, 2013, the Company had 110.1 million remaining shares of Common Stock authorized to be issued under its charter.
	During the years ended December 31, 2013, 2012 and 2011, we recognized $6.9 million, $7.6 million and $6.1 million, respectively, of share-based compensation expense. Because REITs generally do not pay income taxes, we do not realize tax benefits on share-based payments. At December 31, 2013, there was $4.0 million of total unrecognized share-based compensation costs, which will be recognized over a weighted average remaining contractual term of 2.3 years.
	- Stock Options
	Stock options issued prior to 2005 vest ratably over four years and remain outstanding for 10 years. Stock options issued from 2005 through 2013 vest ratably over a four-year period and remain outstanding for 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 fair values of options granted during 2013, 2012 and 2011 were $6.50, $5.47 and $6.47, respectively, per option. The fair values of the options granted were determined at the grant dates using the following assumptions:
		2013			2012			2011
	Risk free interest rate (1)	1	%		1.1	%		2.4	%
	Common stock dividend yield (2)	4.7	%		5.3	%		5	%
	Expected volatility (3)	32.4	%		33.4	%		32.5	%
	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.

Of these exercisable options, 134,628 had exercise prices higher than the market price of our Common Stock at December 31, 2013.
	Cash received or receivable from options exercised was $12.5 million, $7.4 million and $11.9 million for the years ended December 31, 2013, 2012 and 2011, respectively. The total intrinsic value of options exercised during the years ended December 31, 2013, 2012 and 2011 was $3.9 million, $1.9 million and $3.0 million, respectively. The total intrinsic value of options outstanding at December 31, 2013, 2012 and 2011 was $4.3 million, $5.0 million and $3.3 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 one year. The Company has a policy of issuing new shares to satisfy stock option exercises.
	- Time-Based Restricted Stock
	Shares of time-based restricted stock issued to officers and certain employees generally vest 25% on the first, second, third and fourth anniversary dates, respectively. Shares of time-based restricted stock issued to directors generally vest 25% on January 1 of each successive year after the grant date. The value of grants of time-based restricted stock is based on the market value of Common Stock as of the date of grant and is amortized to expense over the respective vesting period or the service period, if shorter, for employees who are or will become eligible under the Company's retirement plan.

Vested shares include those shares surrendered by employees to satisfy tax withholding obligations in connection with such vesting.
- Total Return-Based Restricted Stock
During 2013, 2012 and 2011, the Company issued shares of total return-based restricted stock to officers that will vest based on (1) the Company's absolute total returns for certain pre-determined three-year periods relative to defined target returns and (2) whether the Company's total return exceeds the average total returns of a selected group of peer companies. The amount subject to vesting ranges from zero to 150% with respect to total return-based restricted stock issued in 2013 and from zero to 250% with respect to total return-based restricted stock issued in 2012 and 2011. The grant date fair value of such shares of total return-based restricted stock was determined to be $31.73, $38.71 and $41.02, 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:
	2013			2012			2011
Risk free interest rate (1)	0.4	%		0.4	%		1	%
Common stock dividend yield (2)	4.9	%		5.4	%		5.4	%
Expected volatility (3)	43.4	%		43.7	%		42.8	%
__________
-1	Represents the interest rate as of the grant date on US treasury bonds having the same life as the estimated life of the total return-based restricted stock grants.
-2	The dividend yield is calculated utilizing the 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.

-1	The fair value at grant date of total return-based restricted stock issued during the years ended December 31, 2013, 2012 and 2011 was $2.1 million, $2.6 million and $2.4 million, respectively.
-2	The vesting date fair value of total return-based restricted stock that vested during the years ended December 31, 2013, 2012 and 2011 was $1.5 million, $1.1 million and $2.0 million, respectively. Vested shares include those shares surrendered by employees to satisfy tax withholding obligations in connection with such vesting.
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, 2013, 2012 and 2011, we contributed $1.1 million, $1.0 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. Administrative expenses of the plan are paid by us.
Retirement Plan
The Company has adopted a retirement plan applicable to all employees who, at the time of retirement, have at least 30 years of continuous qualified service or are at least 55 years old and have at least 10 years of continuous qualified service. Subject to advance written notice and compliance with a non-compete agreement with us, 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 granted to such eligible retiree during his or her employment 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 originally granted to such eligible retiree during his or her employment that subsequently vests after the retirement date according to the terms of their original grants. For employees who meet the age and service eligibility requirements, 100% of their annual grants are expensed at the grant date as if fully vested. For employees who will meet the age and service eligibility requirements within the normal vesting periods, the grants are amortized over the shorter service period.

Deferred Compensation
Prior to 2010, officers could elect to defer all or a portion of their cash compensation, which was then invested in unrelated mutual funds under our non-qualified deferred compensation plan. These investments are recorded at fair value, which aggregated $4.0 million and $3.4 million at December 31, 2013 and 2012, 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,
	2013				2012				2011
Beginning deferred compensation liability	$	3,354			$	3,149			$	4,091

Total deferred compensation liability	$	3,996			$	3,354			$	3,149
Employee Stock Purchase Plan
The Company has an Employee Stock Purchase Plan pursuant to which employees generally 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 cash contributions and cash received from dividends on shares held under the Plan, are used 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, 2013, 2012 and 2011, the Company issued 27,250, 34,126 and 30,826 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, 2013, 2012 and 2011. As a general rule, shares purchased under the Plan must be held for at least one year.

	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 we engage in certain types of transactions.
	The minimum dividend per share of Common Stock required for the Company to maintain its REIT status was $1.08, $1.07 and $1.01 per share in 2013, 2012 and 2011, 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 prescribed in the Code. The tax basis of the Company's assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $3.4 billion and $2.1 billion, respectively, at December 31, 2013 and $2.9 billion and $2.0 billion, respectively, at December 31, 2012. The tax basis of the Operating Partnership's assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $3.4 billion and $2.1 billion, respectively, at December 31, 2013 and $2.9 billion and $2.0 billion, respectively, at December 31, 2012.
	During the years ended December 31, 2013, 2012 and 2011, the Company qualified as a REIT, distributed the necessary amount of taxable income and, therefore, 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.
	At December 31, 2013 and 2012, the taxable REIT subsidiary had net deferred tax liabilities of $1.8 million and $2.2 million, respectively, comprised primarily of tax versus book basis differences in certain investments held by the taxable REIT subsidiary. At December 31, 2012, the taxable REIT subsidiary had a $2.1 million net deferred tax asset for cumulative tax loss carryforwards that was realized in 2013 in conjunction with recording our share of the gain recognized by Weston Lofts upon the sale of 215 residential units. The taxable REIT subsidiary incurred $2.1 million of income tax expense in 2013, including $1.7 million netted against the gain included in equity in earnings of unconsolidated affiliates. Income taxes are not material to our operating results or financial position.
	The Company is subject to federal, state and local income tax examinations by tax authorities for 2010 through 2013.

	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 and, at December 31, 2013, no single customer generated more than 10.0% of our consolidated revenues on an annualized basis.
	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:

	During 2010, we sold seven office properties in Winston Salem, NC for gross proceeds of $12.9 million. In connection with this disposition, we received cash of $4.5 million and provided seller financing of $8.4 million (recorded at fair value of $8.4 million in mortgages and notes receivable) and committed to lend up to an additional $1.7 million for tenant improvements and lease commissions, of which $0.8 million was funded as of December 31, 2013. We accounted for this disposition using the installment method, whereby the $0.4 million gain on disposition of property was deferred until the seller financing is repaid. On January 8, 2014, the $9.2 million outstanding amount was fully repaid. Accordingly, the related $0.4 million gain will be recorded in the first quarter of 2014.

Description of Business and Significant Accounting Policies [Line Items]	'
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 the 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 $138.2 million, $118.2 million and $106.8 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and are stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction.
	Expenditures directly related to the leasing of properties are included in deferred 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 include primarily compensation, benefits and other costs, such as legal fees related to leasing activities, that are incurred in connection with successfully obtaining leases of properties. 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.
	1.    Description of Business and Significant Accounting Policies – Continued
	Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the sale of the asset has been duly approved by the Company, a legally enforceable contract has been executed and the buyer's due diligence period has expired.
Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates	'
	Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates
	With respect to assets classified as held for use, we perform an impairment analysis if events or changes in circumstances indicate that the carrying value may be impaired, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset's carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete.
	If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and are subject to future events that may alter our assumptions, the discounted and/or undiscounted future operating and residual cash flows estimated by us in our impairment analyses or those established by appraisal may not be achieved and we may be required to recognize future impairment losses on properties held for use.
	We record assets held for sale at the lower of the carrying amount or estimated fair value. Fair value of assets held for sale is equal to the estimated or contracted sales price with a potential buyer, less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value.
	We also analyze our investments in unconsolidated affiliates for impairment. This analysis consists of determining whether an expected loss in market value of an investment is other than temporary by evaluating the length of time and the extent to which the market value has been less than cost, the financial condition and near-term prospects of the investee, 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.
	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 the customer 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 terms and other customer lease provisions. Leases are not uniform in dealing with such cost recovery income and there are many variations in the computation. Many customers make monthly fixed payments of CAM, real estate taxes and other cost reimbursement items. We accrue income related to these payments each month. We make quarterly accrual adjustments, positive or negative, to cost recovery income to adjust the recorded amounts to our best estimate of the final annual amounts to be billed and collected. After the end of the calendar year, we compute each customer's final cost recovery income and, after considering amounts paid by the customer during the year, issue a bill or credit for the appropriate amount to the customer. The differences between the amounts billed less previously received payments and the accrual adjustment are recorded as increases or decreases to cost recovery income when the final bills are prepared, which occurs during the first half of the subsequent year.
Allowance for Doubtful Accounts	'
	Allowance for Doubtful Accounts
	Accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable are reduced by an allowance for amounts that may become uncollectible in the future. We regularly evaluate the adequacy of our allowance for doubtful accounts. The evaluation primarily consists of reviewing past due account balances and considering such factors as the credit quality of our customer, historical trends of the customer and changes in customer payment terms. Additionally, with respect to customers in bankruptcy, we estimate the probable recovery through bankruptcy claims and adjust the allowance for amounts deemed uncollectible. If our assumptions regarding the collectability of receivables prove incorrect, we could experience losses in excess of our allowance for doubtful accounts. The allowance and its related receivable are written-off when we have concluded there is a low probability of collection and we have discontinued collection efforts.
Discontinued Operations	'
	Discontinued Operations
	Properties that are sold or classified as held for sale are classified as discontinued operations provided that (1) the operations and cash flows of the property will be eliminated from our ongoing operations and (2) we will not have any significant continuing involvement in the operations of the property after it is sold. Interest expense is included in discontinued operations if the related loan securing the sold property is to be paid off or assumed by the buyer in connection with the sale. 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. If the property is contributed 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.
Lease Incentives	'
	Lease Incentives
	Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign the 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.
For Sale Residential Condominiums	'
	For-Sale Residential Condominiums
	For-sale residential condominiums include completed, but unsold, condominium inventory. We initially record receipts of earnest money deposits in accounts payable, accrued expenses and other liabilities in accordance with the deposit method. We then record completed sales when units close and the remaining net cash is received. All for-sale residential condominiums were sold as of December 31, 2012.
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.
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.
	1.    Description of Business and Significant Accounting Policies – Continued
	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, 2013, properties that we wholly own were leased to 1,793 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Raleigh, NC, Atlanta, GA, Tampa, FL, Nashville, TN and Pittsburgh, PA. Our customers engage in a wide variety of businesses. No single customer of the properties that we wholly own generated more than 10.0% of our consolidated revenues during 2013.
	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 subjects our balance to the credit risk of the institution.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	We borrow funds at a combination of fixed and variable rates. Borrowings under our revolving credit facility and bank term loans bear interest at variable rates. Our long-term debt typically bears interest at fixed rates. Our interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and 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.
	1.    Description of Business and Significant Accounting Policies – Continued
	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.

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 fair values of options granted during 2013, 2012 and 2011 were $6.50, $5.47 and $6.47, respectively, per option. The fair values of the options granted were determined at the grant dates using the following assumptions:

[1]	For the year ended December 31, 2013, as a result of acquiring our joint venture partner's 60.0% interest in 2013, we consolidated a joint venture previously accounted for under the equity method of accounting.
[2]	Our share of scheduled future principal payments, including amortization, due on mortgages and notes payable at December 31, 2013 is as follows:2014$11,011201599220161,062201727,082201819,397Thereafter4,880 $64,424 All of this joint venture debt is non-recourse to us except in the case of customary exceptions pertaining to such matters as misuse of funds, environmental conditions, material misrepresentations and voluntary or uncontested involuntary bankruptcy events.
[3]	This amount represents the aggregate difference between our historical cost basis and the basis reflected at the joint venture level, which is depreciated over the life of the related asset.
