Description of Business

Highwoods Properties, Inc., together with its consolidated subsidiaries (the “Company”), is a fully-integrated, self-administered and self-managed equity 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 virtually all of its activities through Highwoods Realty Limited Partnership (the “Operating Partnership”). At December 31, 2011, the Company and/or the Operating Partnership wholly owned: 303 in-service office, industrial and retail properties, comprising 29.3 million square feet; 96 rental residential units; 17 for-sale residential condominiums; 586 acres of undeveloped land suitable for future development, of which 524 acres are considered core assets; one office property under development; and one office property that is considered completed but not yet stabilized. In addition, we owned interests (50.0% or less) in 35 in-service office properties, one rental residential property under development and 11 acres of undeveloped land suitable for future development, which includes a 12.5% interest in a 261,000 square foot office property directly owned by the Company (not included in the Operating Partnership’s Consolidated Financial Statements).

The Company is the sole general partner of the Operating Partnership. At December 31, 2011, the Company owned all of the Preferred Units and 72.2 million, or 95.1%, of the Common Units in the Operating Partnership. Limited partners, including one officer and two directors of the Company, own the remaining 3.7 million Common Units. In the event the Company issues shares of Common Stock, the proceeds of the issuance are contributed to the Operating Partnership in exchange for additional Common Units. Generally, the Operating Partnership is required to redeem each Common Unit at the request of the holder thereof for cash equal to the value of one share of the Company’s Common Stock, $0.01 par value, 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 2011, the Company redeemed 64,469 Common Units for a like number of shares of Common Stock. The redemptions, in conjunction with the proceeds from issuances of Common Stock contributed to the Operating Partnership in exchange for additional Common Units, increased the percentage of Common Units owned by the Company from 95.0% at December 31, 2010 to 95.1% at December 31, 2011.

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 Sheet at December 31, 2010 was revised from previously reported amounts to reflect in real estate and other assets, net, held for sale those properties which qualified as held for sale during 2011. Our Consolidated Statements of Income for the years ended December 31, 2010 and 2009 were revised from previously reported amounts to reflect in discontinued operations the operations for those properties sold or held for sale subsequent to those respective years.

The Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those subsidiaries in which we own a majority voting interest with the ability to control operations of the subsidiaries and where no substantive participating rights or substantive kick out rights have been granted to the noncontrolling interests. 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 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, 2011, we had involvement with no entities that we concluded to be variable interest entities. All significant 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.

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 $120.8 million, $117.6 million and $115.6 million for the years ended December 31, 2011, 2010 and 2009, 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 one 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 securing 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. 

1.    Description of Business and Significant Accounting Policies – Continued

The above and below market rate portions of leases acquired in connection with property acquisitions are recorded in deferred financing and leasing costs and in accounts payable, accrued expenses and other liabilities, respectively, at fair value and amortized into rental revenue over the remaining term of the respective leases as described below. Fair value is calculated as the present value of the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) our estimate of fair market lease rates for each corresponding in-place lease, using a discount rate that reflects the risks associated with the leases acquired and measured over a period equal to the remaining initial term of the lease for above-market leases and the remaining initial term plus the term of any renewal option that the customer would be economically compelled to exercise for below-market leases.

In-place leases acquired are recorded at fair value in deferred financing and leasing costs and are amortized to depreciation and amortization expense over the remaining term of the respective lease. The value of in-place leases is based on our evaluation of the specific characteristics of each customer's lease. Factors considered include estimates of carrying costs during hypothetical expected lease-up periods, current market conditions, the customer's credit quality and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider tenant improvements, leasing commissions and legal and other related expenses.
 
Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the Company's Board of Directors, or its Investment Committee, has approved the sale of the asset, a legally enforceable contract has been executed and the buyer's due diligence period has expired.

Impairment of Long-Lived 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 impacts 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 our properties held for use.
 
We record assets held for sale, including for-sale residential condominiums, 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.


1.    Description of Business and Significant Accounting Policies – Continued

Sales of Real Estate
 
For sales transactions meeting the requirements for full profit recognition, the related assets and liabilities are removed from the balance sheet and the resultant gain or loss is recorded in the period the transaction closes. For sales transactions with continuing involvement after the sale, if the continuing involvement with the property is limited by the terms of the sales contract, profit is recognized at the time of sale and is reduced by the maximum exposure to loss related to the nature of the continuing involvement. Sales to entities in which we have or receive an interest are accounted for using partial sale accounting.
 
For transactions that do not meet the criteria for a sale, we evaluate the nature of the continuing involvement, including put and call provisions, if present, and account for the transaction as a financing arrangement, profit-sharing arrangement, leasing arrangement or other alternate method of accounting, rather than as a sale, based on the nature and extent of the continuing involvement. Some transactions may have numerous forms of continuing involvement. In those cases, we determine which method is most appropriate based on the substance of the transaction.

Rental and Other Revenues
 
Minimum contractual rents from leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Contingent rental revenue, such as percentage rent, is accrued when the contingency is removed. Termination fee income is recognized at the later of when the customer has vacated the space or the lease has expired and a fully executed lease termination agreement has been delivered, the amount of the fee is determinable and collectability of the fee is reasonably assured. Rental revenue reductions related to co-tenancy lease provisions, if any, are accrued when events have occurred that trigger such provisions.

Property operating cost recovery revenues from customers (“cost reimbursements”) are determined on a calendar year and a lease-by-lease basis. The most common types of cost reimbursements 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 a base year amount. The computation of cost reimbursements 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 reimbursements 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 with respect to the cost reimbursements. After the end of the calendar year, we compute each customer's final cost reimbursements 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.


1.    Description of Business and Significant Accounting Policies – Continued

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 the property is sold to a joint venture in which we retain an interest, the property will not be accounted for as a discontinued operation due to our significant ongoing interest in the operations through our joint venture interest. If we are retained to provide property management, leasing and/or other services for the property owner after the sale, the property generally will be accounted for as a discontinued operation because the expected cash flows related to our management and leasing activities generally will not be significant in comparison to the cash flows from the property prior to sale.
 
Lease Incentives
 
Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign 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.

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 security deposits from sales contracts on for-sale residential condominiums, 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 given to lenders to unencumber secured properties.
 

1.    Description of Business and Significant Accounting Policies – Continued

Income Taxes
 
We have elected and expect 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, we are required to pay dividends to our stockholders equal to at least 90.0% of our annual REIT taxable income, excluding net capital gains.
 
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, 2011, our Wholly Owned Properties were leased to 1,722 customers. The geographic locations that comprise greater than 10.0% of our annualized cash rental revenue are Raleigh, NC, Tampa, FL, Atlanta, GA and Nashville, TN. Our customers engage in a wide variety of businesses. No single customer of the Wholly Owned Properties generated more than 10.0% of our consolidated revenues during 2011.

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, construction facility and bank term loans bear interest at variable rates. Our long-term debt, which consists of secured and unsecured long-term financings and the issuance of unsecured debt securities, typically bears interest at fixed rates although some loans bear interest at variable rates. Our interest rate risk management objectives are to limit 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 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. We also enter into treasury lock and similar agreements from time to time in order to limit our exposure to an increase in interest rates with respect to future debt offerings.
 
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 and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings. Interest rate hedge contracts typically contain a provision whereby if we default on any of our indebtedness, we could also be declared in default on our hedge contracts.

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.

1.    Description of Business and Significant Accounting Policies – Continued

Earnings Per Share
 
Basic earnings per share 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 since dividends received on such restricted stock are non-forfeitable.
 
Recently Issued Accounting Standards
 
Beginning with our Quarterly Report on Form 10-Q for the three months ended March 31, 2012, we will be required to enhance our disclosure of assets and liabilities measured at fair value. This includes disclosing any significant transfers between Levels 1 and 2 of the fair value hierarchy, additional quantitative and qualitative information regarding fair value measurements categorized as Level 3 of the fair value hierarchy and the hierarchy classification for items whose fair value is not recorded on our Consolidated Balance Sheets but is disclosed in our Notes to Consolidated Financial Statements. Additionally, we will be required to present comprehensive income on the face of our Consolidated Statements of Income, which is currently disclosed in our Notes to Consolidated Financial Statements.

Description of Business and Significant Accounting Policies

Highwoods Properties, Inc., together with its consolidated subsidiaries (the “Company”), is a fully-integrated, self-administered and self-managed equity 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 virtually all of its activities through Highwoods Realty Limited Partnership (the “Operating Partnership”). At December 31, 2011, the Company and/or the Operating Partnership wholly owned: 303 in-service office, industrial and retail properties, comprising 29.3 million square feet; 96 rental residential units; 17 for-sale residential condominiums; 586 acres of undeveloped land suitable for future development, of which 524 acres are considered core assets; one office property under development; and one office property that is considered completed but not yet stabilized. In addition, we owned interests (50.0% or less) in 35 in-service office properties, one rental residential property under development and 11 acres of undeveloped land suitable for future development, which includes a 12.5% interest in a 261,000 square foot office property directly owned by the Company (not included in the Operating Partnership’s Consolidated Financial Statements).

The Company is the sole general partner of the Operating Partnership. At December 31, 2011, the Company owned all of the Preferred Units and 72.2 million, or 95.1%, of the Common Units in the Operating Partnership. Limited partners, including one officer and two directors of the Company, own the remaining 3.7 million Common Units. In the event the Company issues shares of Common Stock, the proceeds of the issuance are contributed to the Operating Partnership in exchange for additional Common Units. Generally, the Operating Partnership is required to redeem each Common Unit at the request of the holder thereof for cash equal to the value of one share of the Company’s Common Stock, $0.01 par value, 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 2011, the Company redeemed 64,469 Common Units for a like number of shares of Common Stock. The redemptions, in conjunction with the proceeds from issuances of Common Stock contributed to the Operating Partnership in exchange for additional Common Units, increased the percentage of Common Units owned by the Company from 95.0% at December 31, 2010 to 95.1% at December 31, 2011.

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 Sheet at December 31, 2010 was revised from previously reported amounts to reflect in real estate and other assets, net, held for sale those properties which qualified as held for sale during 2011. Our Consolidated Statements of Income for the years ended December 31, 2010 and 2009 were revised from previously reported amounts to reflect in discontinued operations the operations for those properties sold or held for sale subsequent to those respective years.

The Consolidated Financial Statements include wholly owned subsidiaries and those subsidiaries in which we own a majority voting interest with the ability to control operations of the subsidiaries and where no substantive participating rights or substantive kick out rights have been granted to the noncontrolling interests. 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 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, 2011, we had involvement with no entities that we concluded to be variable interest entities. All significant intercompany transactions and accounts have been eliminated.

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 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 $120.8 million, $117.6 million and $115.6 million for the years ended December 31, 2011, 2010 and 2009, 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 one 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.

The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. 

1.    Description of Business and Significant Accounting Policies – Continued

The above and below market rate portions of leases acquired in connection with property acquisitions are recorded in deferred financing and leasing costs and in accounts payable, accrued expenses and other liabilities, respectively, at fair value and amortized into rental revenue over the remaining term of the respective leases as described below. Fair value is calculated as the present value of the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) our estimate of fair market lease rates for each corresponding in-place lease, using a discount rate that reflects the risks associated with the leases acquired and measured over a period equal to the remaining initial term of the lease for above-market leases and the remaining initial term plus the term of any renewal option that the customer would be economically compelled to exercise for below-market leases.

In-place leases acquired are recorded at fair value in deferred financing and leasing costs and are amortized to depreciation and amortization expense over the remaining term of the respective lease. The value of in-place leases is based on our evaluation of the specific characteristics of each customer's lease. Factors considered include estimates of carrying costs during hypothetical expected lease-up periods, current market conditions, the customer's credit quality and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider tenant improvements, leasing commissions and legal and other related expenses.
 
Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the Company's Board of Directors, or its Investment Committee, has approved the sale of the asset, a legally enforceable contract has been executed and the buyer's due diligence period has expired.

Impairment of Long-Lived 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 impacts 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 our properties held for use.
 
We record assets held for sale, including for-sale residential condominiums, 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.

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.

Property operating cost recovery revenues from customers (“cost reimbursements”) are determined on a calendar year and a lease-by-lease basis. The most common types of cost reimbursements 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 a base year amount. The computation of cost reimbursements 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 reimbursements 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 with respect to the cost reimbursements. After the end of the calendar year, we compute each customer's final cost reimbursements 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.


1.    Description of Business and Significant Accounting Policies – Continued

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 the property is sold to a joint venture in which we retain an interest, the property will not be accounted for as a discontinued operation due to our significant ongoing interest in the operations through our joint venture interest. If we are retained to provide property management, leasing and/or other services for the property owner after the sale, the property generally will be accounted for as a discontinued operation because the expected cash flows related to our management and leasing activities generally will not be significant in comparison to the cash flows from the property prior to sale.
 
Lease Incentives
 
Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign 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.

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 security deposits from sales contracts on for-sale residential condominiums, 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 given to 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 accompanying balance sheet. The recorded value of the Redeemable Common Units is based on fair value at the balance sheet date as measured by the closing price of Common Stock on that date multiplied by the total number of Redeemable Common Units outstanding. The recorded value of the Preferred Units is based on their redemption value.

Income Taxes

The Company has elected and expects to continue to qualify as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”). A corporate REIT is a legal entity that holds real estate assets and, through the payment of dividends to stockholders, is generally permitted to reduce or avoid the payment of federal and state income taxes at the corporate level. To maintain qualification as a REIT, the Company is required to pay dividends to its stockholders equal to at least 90.0% of its annual REIT taxable income, excluding net capital gains. The partnership agreement requires the Operating Partnership to pay economically equivalent distributions on outstanding Common Units at the same time that the Company pays dividends on its outstanding Common Stock.

Other than income taxes related to its taxable REIT subsidiary, the Operating Partnership does not reflect any federal income taxes in its financial statements, since as a partnership the taxable effects of its operations are attributed to its partners. The Operating Partnership does record state income tax for states that tax partnership income directly.

Concentration of Credit Risk
  
At December 31, 2011, our Wholly Owned Properties were leased to 1,722 customers. The geographic locations that comprise greater than 10.0% of our annualized cash rental revenue are Raleigh, NC, Tampa, FL, Atlanta, GA and Nashville, TN. Our customers engage in a wide variety of businesses. No single customer of the Wholly Owned Properties generated more than 10.0% of our consolidated revenues during 2011.

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, construction facility and bank term loans bear interest at variable rates. Our long-term debt, which consists of secured and unsecured long-term financings and the issuance of unsecured debt securities, typically bears interest at fixed rates although some loans bear interest at variable rates. Our interest rate risk management objectives are to limit 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 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. We also enter into treasury lock and similar agreements from time to time in order to limit our exposure to an increase in interest rates with respect to future debt offerings.
 

1.    Description of Business and Significant Accounting Policies – Continued

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 and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings. Interest rate hedge contracts typically contain a provision whereby if we default on any of our indebtedness, we could also be declared in default on our hedge contracts.

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 Unit
 
Basic earnings per unit 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 include all of the Company's unvested restricted stock since dividends received on such restricted stock are non-forfeitable.

Recently Issued Accounting Standards
 
Beginning with our Quarterly Report on Form 10-Q for the three months ended March 31, 2012, we will be required to enhance our disclosure of assets and liabilities measured at fair value. This includes disclosing any significant transfers between Levels 1 and 2 of the fair value hierarchy, additional quantitative and qualitative information regarding fair value measurements categorized as Level 3 of the fair value hierarchy and the hierarchy classification for items whose fair value is not recorded on our Consolidated Balance Sheets but is disclosed in our Notes to Consolidated Financial Statements. Additionally, we will be required to present comprehensive income on the face of our Consolidated Statements of Income, which is currently disclosed in our Notes to Consolidated Financial Statements.

Acquisitions

In 2011, we acquired a six-building, 1.54 million square foot office complex in Pittsburgh, PA for a purchase price of $188.5 million. The purchase price included the assumption of secured debt recorded at fair value of $124.5 million, with an effective interest rate of 4.27%, including amortization of deferred financing costs. This debt matures in November 2017. We expensed $4.0 million of costs related to this acquisition, which are included in general and administrative expense. Additionally, we acquired a 503,000 square foot office building in Atlanta, GA for a purchase price of $78.3 million. The purchase price included the assumption of secured debt recorded at fair value of $67.9 million, with an effective interest rate of 5.45%, including amortization of deferred financing costs. This debt matures in January 2014. We expensed $0.3 million of costs related to this acquisition.

In 2011, we also acquired a 48,000 square foot medical office property in Raleigh, NC for approximately $8.9 million in cash and incurred $0.1 million of acquisition-related costs, which are included in general and administrative expense.

In 2010, we acquired a 336,000 square foot office property in Memphis, TN for a purchase price of $52.6 million. The purchase price included the assumption of secured debt recorded at fair value of $40.3 million, with an effective interest rate of 6.43%. This debt matures in November 2015. We incurred $0.4 million of acquisition-related costs. We also acquired a 117,000 square foot office property and 32.6 acres of development land in Tampa, FL for a purchase price of $12.0 million. We incurred $0.2 million of acquisition-related costs. Lastly, we acquired our partner’s interest in a joint venture that owned for-sale residential condominiums for a purchase price of $0.5 million.

In 2009, we acquired a 220,000 square foot office building in Tampa, FL for a purchase price of $22.3 million. We expensed $0.1 million of costs related to this acquisition.

Dispositions

In 2011, we sold an office property and adjacent land parcel in a single transaction in Winston-Salem, NC for gross proceeds of $15.0 million. We recorded gain on disposition of discontinued operations of $2.6 million related to the office property and gain on disposition of property of $0.3 million related to the land.

In 2010, we sold seven office properties in Winston Salem, NC and six industrial properties in Greensboro, NC in two separate transactions for gross proceeds of $24.9 million. In the aggregate, we received cash of $7.9 million. provided seller financing of $17.0 million and committed to lend up to an additional $1.7 million for tenant improvements and lease commissions, of which $0.2 million was funded as of December 31, 2011. We have accounted for these dispositions using the installment method, whereby the $0.4 million gain on disposition of property related to the office properties has been deferred and will be recognized when the seller financing is repaid, and recorded impairment of $0.3 million related to the industrial properties. In 2010, we also recorded a completed sale in connection with the disposition of an office property in Raleigh, NC in the fourth quarter of 2009 where the buyer's limited right to compel us to repurchase the property expired and recorded a gain of $0.2 million.

In 2009, we sold 517,000 square feet of non-core retail and office properties for gross proceeds of $78.2 million and recorded gains of $21.7 million.

Impairments

In 2011, we recorded impairment of assets held for use of $2.4 million on two office properties located in Orlando, FL due to a change in the assumed timing of future disposition, which reduced the future expected cash flows from the properties.


2.     Real Estate Assets - Continued

In 2009, we recorded impairment of assets held for use of $2.6 million on four office properties located in Winston-Salem, NC and recorded impairment of $11.0 million on the office, industrial and retail properties in Winston-Salem and Greensboro, NC that were sold in 2010 and required discontinued operations presentation. These impairments were also due to a change in the assumed timing of future disposition, which reduced the future expected cash flows from the properties.

Our mortgages and notes receivable consist primarily of seller financing issued in conjunction with two disposition transactions in 2010 (see Note 2). This seller financing is evidenced by first mortgages secured by the assignment of rents and the underlying real estate assets. We conclude on the credit quality of the receivables by monitoring the leasing statistics and market fundamentals of these assets. As of December 31, 2011, the payments on both mortgages receivable were current and there were no other indications of impairment on the receivables. We may be required to take impairment charges in the future if and to the extent the underlying collateral diminishes in value.

We may be required to take impairment charges in the future if and to the extent the underlying collateral diminishes in value.

The following summarizes additional information related to certain of our unconsolidated affiliates:

- Lofts at Weston, LLC

In 2011, we and Ravin Partners, LLC (“Ravin”) formed Lofts at Weston, LLC, in which we have a 50.00% 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 is constructing 215 rental residential units at a total cost of approximately $25.9 million. Ravin is the developer, manager and leasing agent and will receive customary fees from the joint venture.

- Highwoods DLF 97/26 DLF 99/32, L.P. (“DLF II”)
 
In 2009, DLF II sold an office property for gross proceeds of $7.1 million and recorded an impairment charge of $0.5 million. We recorded $0.2 million as our proportionate share of this impairment charge through equity in earnings of unconsolidated affiliates.
 
- Kessinger/Hunter, LLC
 
Kessinger/Hunter, LLC, which is managed by our joint venture partner, provides leasing services to certain of our Wholly Owned Properties in Kansas City, MO in exchange for customary fees from us. These services were reduced by us to only leasing-related services in 2009. Kessinger/Hunter, LLC received $2.1 million, $0.8 million and $0.5 million from us for these services in 2011, 2010 and 2009, respectively.
 
- 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.
 
In 2011, we provided a $38.3 million interest-only secured loan to DLF I that is scheduled to mature in March 2012, which was used to repay a secured loan before maturity to a third party lender. The loan bears interest at LIBOR plus 500 basis points, which may be reduced by up to 50 basis points upon the use of proceeds from the sale of certain assets by the joint venture to repay the loan. We recorded $1.3 million of interest income from this loan in interest and other income during the year ended December 31, 2011.

In 2009, DLF I sold an office property for gross proceeds of $14.8 million and recorded a gain of $3.4 million. We recorded $0.8 million as our proportionate share of this gain through equity in earnings of unconsolidated affiliates.
 
- Des Moines, IA Joint Ventures
 
In 2010, we sold our equity interests in a series of unconsolidated joint ventures relating to properties in Des Moines, IA. The assets in the joint ventures included 1.7 million square feet of office, 788,000 square feet of industrial and 45,000 square feet of retail properties, as well as 418 apartment units. In connection with the closing, we received $15.0 million in cash. We had a negative book basis in certain of the joint ventures, primarily as a result of prior cash distributions to the partners. As a result, we recorded gain on disposition of investment in unconsolidated affiliates of $25.3 million.
 
- HIW Development B, LLC
 
In 2011, our joint venture partner exercised its option to acquire our 10.0% equity interest in the HIW Development B, LLC joint venture, which 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.

4.    Investments in and Advances to Affiliates – Continued

- 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. In the years ended December 31, 2011, 2010 and 2009, we recognized $3.1 million, $2.7 million and $2.1 million, respectively, of development, management and leasing fees from our unconsolidated joint ventures. At December 31, 2011 and 2010, we had receivables of $1.0 million and $0.6 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 located in Richmond, VA and receive 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. The organizational documents of Markel require the entity to be liquidated through the sale of its assets upon reaching December 31, 2100. 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 our assets warrant a distribution as determined by the agreement. We estimate the value of noncontrolling interest distributions would have been approximately $14.8 million had the entity been liquidated at December 31, 2011. 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.

- 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 located 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 interest back to us in the future.
 
- Plaza Residential, LLC (“Plaza Residential”)
 
In 2009, our taxable REIT subsidiary formed the Plaza Residential joint venture with an unrelated party to develop and sell 139 for-sale residential condominiums constructed above a wholly owned office property in Raleigh, NC. We initially had a 93.0% interest in Plaza Residential. In 2010, we acquired our partner's 7.0% ownership interest for $0.5 million. During the years ended December 31, 2011, 2010 and 2009, we received $3.2 million, $5.3 million and $13.0 million, respectively, in gross proceeds and recorded $3.5 million, $5.0 million and $12.1 million, respectively, of cost of assets sold from condominium sales, including impairment charges, if any.

In 2011, we obtained a $475.0 million unsecured revolving credit facility, which is scheduled to mature on June 27, 2015 and includes an accordion feature that allows for an additional $75.0 million of borrowing capacity subject to additional lender commitments. Assuming no defaults have occurred, we have an option to extend the maturity for an additional year. The interest rate at our current credit ratings is LIBOR plus 150 basis points and the annual facility fee is 35 basis points. The interest rate and facility fee are based on the higher of the publicly announced ratings from Moody's Investors Service or Standard & Poor's Ratings Services. We use our revolving credit facility for working capital purposes and for the short-term funding of our development and acquisition activity and, in certain instances, the repayment of other debt. Continuing ability to borrow under the revolving credit facility allows us to quickly capitalize on strategic opportunities at short-term interest rates. There was $362.0 million and $148.0 million outstanding under our revolving credit facility at December 31, 2011 and February 1, 2012, respectively. At both December 31, 2011 and February 1, 2012, we had $0.2 million of outstanding letters of credit, which reduces the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility at December 31, 2011 and February 1, 2012 was $112.8 million and $326.8 million, respectively.

In 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. The proceeds were used to pay off at maturity a $137.5 million unsecured bank term loan bearing interest of LIBOR plus 110 basis points, pay off amounts then outstanding under our revolving credit facility and for general corporate purposes.

In 2010, we repaid $10.0 million of our $20.0 million, three-year unsecured term loan. Additionally, we repaid the $5.8 million remaining balance outstanding on the mortgage payable secured by our 96 rental residential units to unencumber these assets for a planned development project. We incurred a penalty of $0.6 million related to this early repayment, which is included in loss on debt extinguishment.

In 2009, we paid off at maturity $50.0 million of unsecured notes bearing interest of 8.125% and retired the remaining $107.2 million principal amount of a two-tranched secured loan bearing interest of 7.80%. We also obtained a $20.0 million, three-year unsecured term loan bearing interest of 3.90%, a $115.0 million, six and a half-year secured loan bearing interest of 6.88% and a $47.3 million, seven-year secured loan bearing interest of 7.50%. Lastly, we repurchased $8.2 million principal amount of unsecured notes due March 2017 bearing interest of 5.85%.

We are currently in compliance with the debt covenants and other requirements with respect to our outstanding debt.

6.    Mortgages and Notes Payable - Continued

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 66.7% 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 $391.2 million carrying amount of 2017 bonds outstanding and $200.0 million carrying amount of 2018 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.

Derivative Financial Instruments

In 2011, we entered into six forward-starting, floating-to-fixed interest rate swaps for seven-year periods each with respect to an aggregate of $225.0 million LIBOR-based borrowings associated with forecasted issuance of debt. These swaps effectively fix the underlying LIBOR rate at a weighted average of 1.678%. The counterparties under the swaps are major financial institutions. 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, 2011.

Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the next year, we estimate that $2.4 million will be reclassified as an increase to interest expense.

Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the next year, we estimate that $2.4 million will be reclassified as an increase to interest expense.

Harborview
 
Our joint venture partner in Harborview 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 Harborview LP's assets and liabilities, less 3.0%, which amount was intended to cover the normal costs of a sale transaction. Because of the put option, this transaction is accounted for as a financing transaction. Accordingly, the assets, liabilities and operations related to Harborview Plaza, the office property owned by Harborview LP 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 the other partner. 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 initial financing obligation 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 $6.2 million and $10.2 million at December 31, 2011 and 2010, 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 construction of a parking garage, 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 bond 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 underlying 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.
 
Capitalized Ground Lease Obligation
 
The capitalized ground lease obligation represents an obligation to the lessor of land on which we constructed a wholly owned office property. We are obligated to make fixed payments to the lessor through October 2022. The lease provides for fixed price purchase options in the ninth and tenth years of the lease. We initially recorded the land and associated financing obligation at the net present value of the fixed rental payments and purchase option through the ninth year at the inception of the lease using a discount rate of 7.10%. The liability accretes as interest expense until it equals the amount of the purchase option.

Operating Ground Leases
 
Certain Wholly Owned 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 on the straight-line basis for operating ground leases was $1.4 million, $1.5 million and $1.6 million for the years ended December 31, 2011, 2010 and 2009, respectively.

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 $10.3 million was recorded on the Consolidated Balance Sheet at December 31, 2011.
 
Des Moines Joint Ventures

As of the closing date of the 2010 disposition of our interests in the Des Moines, IA joint ventures, the joint ventures had approximately $170.0 million of secured debt, which was non-recourse to us except in the case of customary exceptions pertaining to matters such as misuse of funds, borrower bankruptcy, unpermitted transfers, environmental conditions and material misrepresentations. We have no ongoing lender liability relating to such customary exceptions to non-recourse liability with respect to most, but not all, of the debt. The buyer has agreed to indemnify and hold us harmless from any and all future losses that we suffer as a result of our prior investment in the joint ventures, except for losses directly resulting from our acts or omissions. In the event we are exposed to any such future loss, our financial condition and operating results would not be adversely affected unless the buyer defaults on its indemnification obligation.

Rent Guarantees

In connection with the disposition of six industrial properties in Piedmont Triad, NC in the second quarter of 2010, we entered into a limited rent guarantee agreement with the buyer relating to an existing 237,500 square foot lease with one customer, who has leased space in the properties for 14 years. This agreement guarantees the payment of rent for an approximate two-year period from March 2011 through June 2013 in the event the customer exercises its limited termination right. As of December 31, 2011, our maximum exposure under this rent guarantee agreement was approximately $0.3 million. No accrual was recorded for this guarantee because we have concluded that a loss was not probable.

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 are 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 $0.6 million were made in each of the years ended December 31, 2011, 2010 and 2009. The balance at December 31, 2011 and 2010 was $0.8 million and $1.2 million, respectively, which is included in accounts payable, accrued expenses and other liabilities.
 
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 the Operating Partnership

Noncontrolling interests in the Operating Partnership relate to the ownership of Common Units by various individuals and entities other than the Company. Net income attributable to noncontrolling interests in the Operating Partnership is computed by applying the weighted average percentage of Common Units not owned by the Company 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.

Disclosure About Fair Value of Financial Instruments

The following summarizes the three levels of inputs that we use to measure fair value, as well as the assets, noncontrolling interests in the Operating Partnership and liabilities that we recognize at fair value using those levels of inputs.

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 noncontrolling interests in the Operating Partnership relate to the ownership of Common Units by various individuals and entities other than the Company. Our Level 1 liability is our non-qualified deferred compensation obligation.

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 liabilities are interest rate swaps that were outstanding at December 31, 2011 whose fair value 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 are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves. In addition, credit valuation adjustments are incorporated in the fair values to account for potential nonperformance risk.

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 are our tax increment financing bond, which is not routinely traded but whose fair value is determined using the income approach to estimate the projected redemption value based on quoted bid/ask prices for similar unrated municipal bond and real estate assets and for-sale residential condominiums recorded at fair value on a non-recurring basis as a result of our quarterly impairment analyses, which were valued using broker opinion of value and substantiated by internal cash flow projections.

The following tables set forth the assets, noncontrolling interests in the Operating Partnership and liabilities that we measure at fair value by level within the fair value hierarchy. We determine the level based on the lowest level of substantive input used to determine fair value.

In 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, 2011 was $2.3 million below the outstanding principal due on the bond. If the yield-to-maturity used to fair value this bond was 100 basis points higher or lower, the fair value of the bond would have been $0.6 million lower or $0.6 million higher, respectively, as of December 31, 2011. Currently, 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 and, therefore, we have recorded no credit losses related to the bond in the years ended December 31, 2011 and 2010. There is no legal right of offset with the liability, which we report as a financing obligation, related to this tax increment financing bond.

In 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, 2011 was $2.3 million below the outstanding principal due on the bond. If the yield-to-maturity used to fair value this bond was 100 basis points higher or lower, the fair value of the bond would have been $0.6 million lower or $0.6 million higher, respectively, as of December 31, 2011. Currently, 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 and, therefore, we have recorded no credit losses related to the bond in the years ended December 31, 2011 and 2010. There is no legal right of offset with the liability, which we report as a financing obligation, related to this tax increment financing bond.

The carrying values of our cash and cash equivalents, restricted cash, accounts receivable, marketable securities of non-qualified deferred compensation plan, tax increment financing bond, non-qualified deferred compensation obligation and noncontrolling interests in the Operating Partnership are equal to or approximate fair value. The fair values of our mortgages and notes receivable, mortgages and notes payable and financing obligations were estimated using the income or market approaches to approximate the price that would be paid in an orderly transaction between market participants on the respective measurement dates.

Warrants
 
Warrants to acquire Common Stock were issued in 1997 and 1999 in connection with property acquisitions. In 2011, 2010 and 2009, there were no warrants exercised. At December 31, 2011 and 2010, there were 15,000 warrants outstanding with an exercise price of $32.50. These warrants have no expiration date.
 
Dividend Reinvestment Plan
 
We have 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. We 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 declared and paid per Common Unit aggregated $1.70 for each of the years ended December 31, 2011, 2010 and 2009.

Redeemable Common Units

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.

Preferred Units
 
In 2011, we redeemed the remaining 2.1 million outstanding 8.0% Series B Cumulative Redeemable Preferred Units for an aggregate redemption price of $52.5 million, excluding accrued distributions. In connection with this redemption, the $1.9 million excess of the redemption cost over the net carrying amount of the redeemed units was recorded as a reduction to net income available for common unitholders.

Warrants

Warrants to acquire Common Stock were issued in 1997 and 1999 in connection with property acquisitions. 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. In 2011, 2010 and 2009, there were no warrants exercised. At December 31, 2011 and 2010, there were 15,000 warrants outstanding with an exercise price of $32.50. These warrants have no expiration date.

Officer, Management and Director Compensation Programs

Our officers participate in an annual non-equity incentive program whereby they are eligible for incentive cash payments based on a percentage of their annual base salary. Each officer has a target annual non-equity incentive payment percentage that ranges from 30% to 130% of base salary depending on the officer’s position. The officer’s actual incentive payment for the year is the product of the target annual incentive payment percentage times a “performance factor,” which can range from zero to 200%. This performance factor depends upon the relationship between how various performance criteria compare with 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. Incentive payments are accrued and expensed in the year earned and are generally paid in the first quarter of the following year.

Certain other employees participate in an annual non-equity incentive program whereby a target annual cash incentive payment is established based upon the job responsibilities of their position. Incentive payment 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 and are generally paid in the first quarter of the following year.

Our 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. 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. 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 already reflected in the grant date fair value. The following table sets forth the number of shares of Common Stock reserved for future issuance:

Employee Benefit Plans - Continued

Of the possible future issuance under equity incentive plans at December 31, 2011, no more than 0.7 million can be in the form of restricted stock. At December 31, 2011, we had 127.4 million remaining shares of Common Stock authorized to be issued under our charter.

During the years ended December 31, 2011, 2010 and 2009, we recognized $6.1 million, $6.6 million and $6.6 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, 2011, there was $5.6 million of total unrecognized share-based compensation costs, which will be recognized over vesting periods that have a weighted average remaining term of 2.1 years.

- Stock Options

Stock options issued prior to 2005 vest ratably over four years and remain outstanding for 10 years. Stock options issued beginning in 2005 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 or service period. The fair values of options granted during 2011, 2010 and 2009 were $6.47, $4.96 and $1.82, respectively, per option. The fair values of the options granted were determined at the grant dates using the following assumptions:

We have 646,029 options exercisable at December 31, 2011 with weighted average exercise price of $31.01, weighted average remaining life of 2.4 years and intrinsic value of $1.1 million. Of these exercisable options, 252,277 had exercise prices higher than the market price of our Common Stock at December 31, 2011.

Cash received or receivable from options exercised was $11.9 million, $4.4 million and $7.4 million for the years ended December 31, 2011, 2010 and 2009, respectively. The total intrinsic value of options exercised during the years ended December 31, 2011, 2010 and 2009 was $3.0 million, $1.7 million and $2.0 million, respectively. The total intrinsic value of options outstanding at December 31, 2011, 2010 and 2009 was $3.3 million, $7.2 million and $10.3 million, respectively. We generally do not permit the net cash settlement of exercised stock options, but do permit net share settlement so long as the shares received are held for at least one year. We have 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 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 or service periods.

- Total Return-Based Restricted Stock

During 2011, 2010 and 2009, we issued shares of total return-based restricted stock to officers that will vest from zero to 250% based on (1) our absolute total returns for the three-year periods ended December 31, 2012, 2013 and 2014, respectively, relative to defined target returns and (2) whether our total return exceeds the average total returns of a selected group of peer companies. The grant date fair value of such shares of total return-based restricted stock was determined to be $41.02, $29.05 and $15.01, respectively, of the market value of a share of Common Stock as of the grant date and is amortized over the respective three-year period.

Retirement Plan

We have adopted a retirement plan applicable to all employees, including officers, 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 retirement notice and execution of a non-compete agreement with us, eligible retirees are entitled to receive a pro rata amount of the annual incentive payment earned during the year of retirement. Stock options and restricted stock granted by us to such eligible retiree during his or her employment would be non-forfeitable and vest according to the terms of their original grants. For employees who meet the age and service eligibility requirements, 100% of their annual grants are deemed fully vested at the grant date.

Deferred Compensation

We have a non-qualified deferred compensation plan pursuant to which each officer and director could elect to defer a portion of their base salary and/or annual non-equity incentive payment (or director fees) which are invested in unrelated mutual funds. These investments are recorded at fair value which aggregated $3.1 million and $3.5 million at December 31, 2011 and 2010, 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. Such deferred compensation is expensed in the period earned by the officers and directors. Deferred amounts ultimately payable to the officers and directors are based on the value of the related mutual fund investments. Accordingly, changes in the value of the marketable mutual fund investments 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 subsequent to the time the compensation is deferred and fully funded. Prior to 2006, as part of the non-qualified deferred compensation plan, officers and directors could elect to defer cash compensation for investment in units of phantom stock. At the end of each calendar quarter, any person who deferred compensation into phantom stock was credited with units of phantom stock at a 15% discount. Dividends on the phantom units were assumed to be issued in additional units of phantom stock at a 15% discount. By the terms of the plan, the cash value of all phantom stock outstanding under the plan was reinvested in unrelated mutual funds as of December 31, 2011.

401(k) Savings Plan

We have a 401(k) 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, 2011, 2010 and 2009, we contributed $1.1 million, $1.0 million and $1.0 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.

Employee Stock Purchase Plan

We have an Employee Stock Purchase Plan pursuant to which employees generally may contribute up to 25% of their base and annual non-equity incentive compensation for the purchase of Common Stock. At the end of each three-month offering period, the contributions in each participant's account balance, which includes accrued dividends, is applied to acquire shares of Common Stock at a cost that was calculated during 2011 at 85% of the average closing price on the New York Stock Exchange on the five days preceding the last day of the quarter and during 2010 and 2009 at 85% of the lower of the average closing price on the New York Stock Exchange on the five consecutive days preceding the first day of the quarter or the five days preceding the last day of the quarter. In the years ended December 31, 2011, 2010 and 2009, the Company issued 30,826, 27,378 and 37,287 shares, respectively, of Common Stock under the Employee Stock Purchase Plan. The discount on newly issued shares is expensed by us as additional compensation and aggregated $0.2 million, $0.1 million and $0.3 million in the years ended December 31, 2011, 2010 and 2009, respectively.

Officer, Management and Director Compensation Programs

The officers of the Company, which is the sole general partner of the Operating Partnership, participate in an annual non-equity incentive program whereby they are eligible for incentive cash payments based on a percentage of their annual base salary. Each officer has a target annual non-equity incentive payment percentage that ranges from 30% to 130% of base salary depending on the officer’s position. The officer’s actual incentive payment for the year is the product of the target annual incentive payment percentage times a “performance factor,” which can range from zero to 200%. This performance factor depends upon the relationship between how various performance criteria compare with 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. Incentive payments are accrued and expensed in the year earned and are generally paid in the first quarter of the following year.

Certain other employees participate in an annual non-equity incentive program whereby a target annual cash incentive payment is established based upon the job responsibilities of their position. Incentive payment 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 and are generally paid in the first quarter of the following year.

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. 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. 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 already reflected in the grant date fair value. The following table sets forth the number of shares of Common Stock reserved for future issuance:

Of the possible future issuance under equity incentive plans at December 31, 2011, no more than 0.7 million can be in the form of restricted stock. At December 31, 2011, the Company had 127.4 million remaining shares of Common Stock authorized to be issued under our charter.

During the years ended December 31, 2011, 2010 and 2009, we recognized $6.1 million, $6.6 million and $6.6 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, 2011, there was $5.6 million of total unrecognized share-based compensation costs, which will be recognized over vesting periods that have a weighted average remaining term of 2.1 years.

- Stock Options

Stock options issued prior to 2005 vest ratably over four years and remain outstanding for 10 years. Stock options issued beginning in 2005 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 or service period. The fair values of options granted during 2011, 2010 and 2009 were $6.47, $4.96 and $1.82, respectively, per option. The fair values of the options granted were determined at the grant dates using the following assumptions:

- Total Return-Based Restricted Stock

During 2011, 2010 and 2009, we issued shares of total return-based restricted stock to officers that will vest from zero to 250% based on (1) our absolute total returns for the three-year periods ended December 31, 2012, 2013 and 2014, respectively, 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.

Our Consolidated Financial Statements include the operations of our taxable REIT subsidiary, which is subject to federal, state and local income taxes on its taxable income. As a REIT, we 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 us to maintain our REIT status was $1.01, $0.32 and $0.89 per share in 2011, 2010 and 2009, respectively. Continued qualification as a REIT depends on our ability to satisfy the dividend distribution tests, stock ownership requirements and various other qualification tests prescribed in the Code. The tax basis of our assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $2.7 billion and $2.0 billion, respectively, at December 31, 2011 and $2.4 billion and $1.6 billion, respectively, at December 31, 2010.

No provision has been made for federal income taxes during the years ended December 31, 2011, 2010 and 2009 because the Company qualified as a REIT, distributed the necessary amount of taxable income and, therefore, incurred no federal income tax expense during the periods. We recorded state income tax expense in rental property and other expenses of $0.1 million, $0.1 million and $0.6 million for the years ended December 31, 2011, 2010 and 2009, respectively. The taxable REIT subsidiary has operated at a cumulative taxable loss through December 31, 2011 of approximately $5.3 million. In addition to the $2.0 million deferred tax asset for these cumulative tax loss carryforwards, the taxable REIT subsidiary also had net deferred tax liabilities of approximately $1.6 million comprised primarily of tax versus book basis differences in certain investments and depreciable assets held by the taxable REIT subsidiary. Because the future tax benefit of the cumulative losses is not assured, the approximate $0.4 million net deferred tax asset position of the taxable REIT subsidiary has been fully reserved as management does not believe that it is more likely than not that the net deferred tax asset will be realized. The tax benefit of the cumulative losses could be recognized for financial reporting purposes in future periods to the extent the taxable REIT subsidiary generates sufficient taxable income.

We are subject to federal, state and local income tax examinations by tax authorities for 2008 through 2011.

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. The taxable REIT subsidiary has operated at a cumulative taxable loss through December 31, 2011 of approximately $5.3 million and has paid no income taxes since its formation. In addition to the $2.0 million deferred tax asset for these cumulative tax loss carryforwards, the taxable REIT subsidiary also had net deferred tax liabilities of approximately $1.6 million comprised primarily of tax versus book basis differences in certain investments and depreciable assets held by the taxable REIT subsidiary. Because the future tax benefit of the cumulative losses is not assured, the approximate $0.4 million net deferred tax asset position of the taxable REIT subsidiary has been fully reserved as management does not believe that it is more likely than not that the net deferred tax asset will be realized. The tax benefit of the cumulative losses could be recognized for financial reporting purposes in future periods to the extent the taxable REIT subsidiary generates sufficient taxable income. Other than income taxes related to its taxable REIT subsidiary, the Operating Partnership recorded state income tax expense in rental property and other expenses of $0.1 million, $0.1 million and $0.5 million for the years ended December 31, 2011, 2010 and 2009, respectively.

The minimum dividend per share of Common Stock required for the Company to maintain its REIT status was $1.01, $0.32 and $0.89 per share in 2011, 2010 and 2009, 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 Company is subject to federal, state and local income tax examinations by tax authorities for 2008 through 2011.
Segment Information
Segment Information 
Segment Information

Our principal business is the operation, acquisition and development of rental real estate properties. We evaluate our business by product type and by geographic location. Each product type has different customers and economic characteristics as to rental rates and terms, cost per 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, 2011, no single customer of the Wholly Owned Properties generated more than 10.0% of our consolidated revenues on an annualized basis.

The following table summarizes the rental and other revenues and net operating income, the primary industry property-level performance metric which is defined as rental and other revenues less rental property and other expenses, for each reportable segment:

Segment Information 
Segment Information

Our principal business is the operation, acquisition and development of rental real estate properties. We evaluate our business by product type and by geographic location. Each product type has different customers and economic characteristics as to rental rates and terms, cost per 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, 2011, no single customer of the Wholly Owned Properties generated more than 10.0% of our consolidated revenues on an annualized basis.

The following table summarizes the rental and other revenues and net operating income, the primary industry property-level performance metric which is defined as rental and other revenues less rental property and other expenses, for each reportable segment:

Description of Business and Significant Accounting Policies Significant Accounting Policies (Policies)
Use of Estimates, Policy [Policy Text Block] 
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, Policy [Policy Text Block] 
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 $120.8 million, $117.6 million and $115.6 million for the years ended December 31, 2011, 2010 and 2009, 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 one 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 securing 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. 

1.    Description of Business and Significant Accounting Policies – Continued

The above and below market rate portions of leases acquired in connection with property acquisitions are recorded in deferred financing and leasing costs and in accounts payable, accrued expenses and other liabilities, respectively, at fair value and amortized into rental revenue over the remaining term of the respective leases as described below. Fair value is calculated as the present value of the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) our estimate of fair market lease rates for each corresponding in-place lease, using a discount rate that reflects the risks associated with the leases acquired and measured over a period equal to the remaining initial term of the lease for above-market leases and the remaining initial term plus the term of any renewal option that the customer would be economically compelled to exercise for below-market leases.

In-place leases acquired are recorded at fair value in deferred financing and leasing costs and are amortized to depreciation and amortization expense over the remaining term of the respective lease. The value of in-place leases is based on our evaluation of the specific characteristics of each customer's lease. Factors considered include estimates of carrying costs during hypothetical expected lease-up periods, current market conditions, the customer's credit quality and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider tenant improvements, leasing commissions and legal and other related expenses.
 
Real estate and other assets are classified as long-lived assets held for use or as long-lived assets held for sale. Real estate is classified as held for sale when the Company's Board of Directors, or its Investment Committee, has approved the sale of the asset, a legally enforceable contract has been executed and the buyer's due diligence period has expired.
Impairment of Long-Lived Assets and Investments in Unconsolidated Affiliates, Policy [Policy Text Block] 
Impairment of Long-Lived Assets and Investments in Unconsolidated Affiliates

Sales of Real Estate, Policy [Policy Text Block] 
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, Policy [Policy Text Block] 
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.

Allowance for Doubtful Accounts, Policy [Policy Text Block] 
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, Policy [Policy Text Block] 
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 the property is sold to a joint venture in which we retain an interest, the property will not be accounted for as a discontinued operation due to our significant ongoing interest in the operations through our joint venture interest. If we are retained to provide property management, leasing and/or other services for the property owner after the sale, the property generally will be accounted for as a discontinued operation because the expected cash flows related to our management and leasing activities generally will not be significant in comparison to the cash flows from the property prior to sale.
Lease Incentives, Policy [Policy Text Block] 
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, Policy [Policy Text Block] 
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.
Investments in Unconsolidated Affiliates, Policy [Policy Text Block] 
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, Policy [Policy Text Block] 
Cash Equivalents
 
We consider highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
Restricted Cash, Policy [Policy Text Block] 
Restricted Cash
 
Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as security deposits from sales contracts on for-sale residential condominiums, 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 given to lenders to unencumber secured properties.
Income Tax, Policy [Policy Text Block] 
Income Taxes
 
We have elected and expect 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, we are required to pay dividends to our stockholders equal to at least 90.0% of our annual REIT taxable income, excluding net capital gains.
 
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, Policy [Policy Text Block] 
Concentration of Credit Risk
 
At December 31, 2011, our Wholly Owned Properties were leased to 1,722 customers. The geographic locations that comprise greater than 10.0% of our annualized cash rental revenue are Raleigh, NC, Tampa, FL, Atlanta, GA and Nashville, TN. Our customers engage in a wide variety of businesses. No single customer of the Wholly Owned Properties generated more than 10.0% of our consolidated revenues during 2011.

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, Policy [Policy Text Block] 
Derivative Financial Instruments
 
We borrow funds at a combination of fixed and variable rates. Borrowings under our revolving credit facility, construction facility and bank term loans bear interest at variable rates. Our long-term debt, which consists of secured and unsecured long-term financings and the issuance of unsecured debt securities, typically bears interest at fixed rates although some loans bear interest at variable rates. Our interest rate risk management objectives are to limit 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 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. We also enter into treasury lock and similar agreements from time to time in order to limit our exposure to an increase in interest rates with respect to future debt offerings.
 
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 and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings. Interest rate hedge contracts typically contain a provision whereby if we default on any of our indebtedness, we could also be declared in default on our hedge contracts.

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, Policy [Policy Text Block] 
Earnings Per Share
 
Basic earnings per share 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 since dividends received on such restricted stock are non-forfeitable.

Our 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. 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. 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 already reflected in the grant date fair value.
