Description of Business

Highwoods Properties, Inc. (the “Company”) is a fully integrated real estate investment trust (“REIT”) that provides leasing, management, development, construction and other customer-related services for its properties and for third parties. The Company conducts its activities through Highwoods Realty Limited Partnership (the “Operating Partnership”). At December 31, 2016, we owned or had an interest in 31.1 million rentable square feet of in-service properties, 1.1 million rentable square feet of office properties under development and approximately 400 acres of development land.

The Company is the sole general partner of the Operating Partnership. At December 31, 2016, the Company owned all of the Preferred Units and 101.3 million, or 97.3%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.8 million Common Units. In the event the Company issues shares of Common Stock, the net proceeds of the issuance are contributed to the Operating Partnership in exchange for additional Common Units. Generally, the Operating Partnership is obligated to redeem each Common Unit at the request of the holder thereof for cash equal to the value of one share of Common Stock based on the average of the market price for the 10 trading days immediately preceding the notice date of such redemption, provided that the Company, at its option, may elect to acquire any such Common Units presented for redemption for cash or one share of Common Stock. The Common Units owned by the Company are not redeemable. During 2016, the Company redeemed 61,048 Common Units for a like number of shares of Common Stock. These redemptions, in conjunction with the proceeds from issuances of Common Stock (see Note 12), increased the percentage of Common Units owned by the Company from 97.1% at December 31, 2015 to 97.3% at December 31, 2016.

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 Statements of Income for the year ended December 31, 2014 were retrospectively revised from previously reported amounts to reclassify the operations for those properties classified as discontinued operations.

The Company's Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership's Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. We consolidate joint venture investments, such as interests in partnerships and limited liability companies, when we control the major operating and financial policies of the investment through majority ownership, in our capacity as a general partner or managing member or through some other contractual right. At December 31, 2016, three properties owned through a joint venture investment were consolidated.

In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. During 2015, we acquired three buildings and a land parcel using special purpose entities owned by qualified intermediaries to facilitate a potential Section 1031 reverse exchange under the Internal Revenue Code. We determined that these entities were variable interest entities of which we were the primary beneficiary; therefore, we consolidated these entities as of December 31, 2015. At such time, these variable interest entities had total assets, liabilities and cash flows of $421.3 million, $16.3 million, and $7.1 million, respectively. During 2016, we subsequently acquired such special purpose entities and therefore own direct title to these buildings.

All intercompany transactions and accounts have been eliminated.

1.    Description of Business and Significant Accounting Policies – Continued

During 2015, as a result of our partner’s irrevocable exercise of a buy-sell provision in our SF-HIW Harborview Plaza, LP ("Harborview") joint venture agreement, our partner’s right to put its 80.0% equity interest back to us became no longer exercisable. As a result, we recorded the original contribution transaction as a partial sale. Our investment in this joint venture then qualified for the equity method of accounting, which resulted in the retrospective revision of our Consolidated Balance Sheets and Consolidated Statements of Equity and Capital for prior periods.

Use of Estimates

The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.

Real Estate and Related Assets

Real estate and related assets are recorded at cost and stated at cost less accumulated depreciation. Renovations, replacements and other expenditures that improve or extend the life of assets are capitalized and depreciated over their estimated useful lives. Expenditures for ordinary maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful life of 40 years for buildings and depreciable land infrastructure costs, 15 years for building improvements and five to seven years for furniture, fixtures and equipment. Tenant improvements are amortized using the straight-line method over initial fixed terms of the respective leases, which generally are from three to 10 years. Depreciation expense for real estate assets was $173.1 million, $168.7 million and $154.4 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and are stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction.

Expenditures directly related to the leasing of properties are included in deferred leasing costs and are stated at amortized cost. Such expenditures are part of the investment necessary to execute leases and, therefore, are classified as investment activities in the statement of cash flows. All leasing commissions paid to third parties for new leases or lease renewals are capitalized. Internal leasing costs, which consist primarily of compensation, benefits and other costs, such as legal fees related to leasing activities, that are incurred in connection with successfully obtaining leases of properties are also capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases, which generally are from three to 10 years. Estimated costs related to unsuccessful activities are expensed as incurred.

We record liabilities for the performance of asset retirement activities when the obligation to perform such activities is probable even when uncertainty exists about the timing and/or method of settlement.

Upon the acquisition of real estate assets, we assess the fair value of acquired tangible assets such as land, buildings and tenant improvements, intangible assets and liabilities such as above and below market leases, acquired in-place leases, customer relationships and other identifiable intangible assets and assumed liabilities. We assess fair value based on estimated cash flow projections that utilize discount and/or capitalization rates as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. 

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

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

Impairments of Real Estate Assets and Investments in Unconsolidated Affiliates

With respect to assets classified as held for use, we perform an impairment analysis if events or changes in circumstances indicate that the carrying value may be impaired, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset's carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete.

If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and are subject to future events that may alter our assumptions, the discounted and/or undiscounted future operating and residual cash flows estimated by us in our impairment analyses or those established by appraisal may not be achieved and we may be required to recognize future impairment losses on properties held for use.
 
We record assets held for sale at the lower of the carrying amount or estimated fair value. Fair value of assets held for sale is equal to the estimated or contracted sales price with a potential buyer, less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value.
 
We also analyze our investments in unconsolidated affiliates for impairment. This analysis consists of determining whether an expected loss in market value of an investment is other than temporary by evaluating the length of time and the extent to which the market value has been less than cost, the financial condition and near-term prospects of the investment, and our intent and ability to retain our investment for a period of time sufficient to allow for any anticipated recovery in market value. As the factors used in this analysis are difficult to predict and 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.

Cost recovery income is determined on a calendar year and a lease-by-lease basis. The most common types of cost recovery income in our leases are common area maintenance (“CAM”) and real estate taxes, for which a customer typically pays its pro-rata share of operating and administrative expenses and real estate taxes in excess of the costs incurred during a contractually specified base year. The computation of cost recovery income is complex and involves numerous judgments, including the interpretation of lease provisions. Leases are not uniform in dealing with such cost recovery income and there are many variations in the computation. Many customers make monthly fixed payments of CAM, real estate taxes and other cost reimbursement items. We accrue income related to these payments each month. We make quarterly accrual adjustments, positive or negative, to cost recovery income to adjust the recorded amounts to our best estimate of the final annual amounts to be billed and collected. After the end of the calendar year, we compute each customer's final cost recovery income and, after considering amounts paid by the customer during the year, issue a bill or credit for the appropriate amount to the customer. The differences between the amounts billed less previously received payments and the accrual adjustment are recorded as increases or decreases to cost recovery income when the final bills are prepared, which occurs during the first half of the subsequent year.
 
Allowance for Doubtful Accounts
 
Accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable are reduced by an allowance for amounts that may become uncollectible in the future. We regularly evaluate the adequacy of our allowance for doubtful accounts. The evaluation primarily consists of reviewing past due account balances and considering such factors as the credit quality of our customer, historical trends of the customer and changes in customer payment terms. Additionally, with respect to customers in bankruptcy, we estimate the probable recovery through bankruptcy claims and adjust the allowance for amounts deemed uncollectible. If our assumptions regarding the collectability of receivables prove incorrect, we could experience losses in excess of our allowance for doubtful accounts. The allowance and its related receivable are written-off when we have concluded there is a low probability of collection and we have discontinued collection efforts.

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 the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results. Interest expense is included in discontinued operations if a related loan securing the sold property is to be paid off or assumed by the buyer in connection with the sale.

Lease Incentives
 
Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign a lease, are capitalized in deferred leasing costs and amortized on a straight-line basis over the respective lease terms as a reduction of rental revenues.

Investments in Unconsolidated Affiliates
 
We account for our joint venture investments using the equity method of accounting when our interests represent a general partnership interest but substantive participating rights or substantive kick out rights have been granted to the limited partners or when our interests do not represent a general partnership interest and we do not control the major operating and financial policies of the investment. These investments are initially recorded at cost as investments in unconsolidated affiliates and are subsequently adjusted for our share of earnings and cash contributions and distributions. To the extent our cost basis at formation of the joint venture is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related assets and included in our share of equity in earnings of unconsolidated affiliates.

Cash Equivalents

We consider highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

Restricted Cash
 
Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as construction-related escrows, property disposition proceeds set aside and designated or intended to fund future tax-deferred exchanges of qualifying real estate investments, escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements and any deposits made with lenders to unencumber secured properties.

Redeemable Common Units and Preferred Units
 
Limited partners holding Common Units other than the Company (“Redeemable Common Units”) have the right to put any and all of the Common Units to the Operating Partnership and the Company has the right to put any and all of the Preferred Units to the Operating Partnership in exchange for their liquidation preference plus accrued and unpaid distributions in the event of a corresponding redemption by the Company of the underlying Preferred Stock. Consequently, these Redeemable Common Units and Preferred Units are classified outside of permanent partners’ capital in the Operating Partnership's accompanying balance sheets. The recorded value of the Redeemable Common Units is based on fair value at the balance sheet date as measured by the closing price of Common Stock on that date multiplied by the total number of Redeemable Common Units outstanding. The recorded value of the Preferred Units is based on their redemption value.

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

1.    Description of Business and Significant Accounting Policies – Continued

Other than income taxes related to its taxable REIT subsidiary, the Operating Partnership does not reflect any federal income taxes in its financial statements, since as a partnership the taxable effects of its operations are attributed to its partners. The Operating Partnership does record state income tax for states that tax partnership income directly.
 
We conduct certain business activities through a taxable REIT subsidiary, as permitted under the Code. The taxable REIT subsidiary is subject to federal, state and local income taxes on its taxable income. We record provisions for income taxes based on its income recognized for financial statement purposes, including the effects of temporary differences between such income and the amount recognized for tax purposes.
 
Concentration of Credit Risk
 
At December 31, 2016, properties that we wholly own were leased to 1,741 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Raleigh, Atlanta, Tampa and Nashville. Our customers engage in a wide variety of businesses. No single customer generated more than 6% of our consolidated revenues during 2016.
 
We maintain our cash and cash equivalents and our restricted cash at financial or other intermediary institutions. The combined account balances at each institution may exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. Additionally, from time to time in connection with tax-deferred 1031 transactions, our restricted cash balances may be commingled with other funds being held by any such intermediary institution, which would subject our balance to the credit risk of the institution.

Derivative Financial Instruments
 
We borrow funds at a combination of fixed and variable rates. Borrowings under our revolving credit facility and bank term loans bear interest at variable rates. Our long-term debt typically bears interest at fixed rates. Our interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and lower our overall borrowing costs. To achieve these objectives, from time to time, we enter into interest rate hedge contracts such as collars, swaps, caps and treasury lock agreements in order to mitigate our interest rate risk with respect to various debt instruments. We generally do not hold or issue these derivative contracts for trading or speculative purposes. The interest rate on all of our variable rate debt is generally adjusted at one or three month intervals, subject to settlements under these interest rate hedge contracts.

Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income/(loss) and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings.
 
We account for terminated derivative instruments by recognizing the related accumulated comprehensive income/(loss) balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated comprehensive income/(loss) into earnings over the originally designated hedge period.

Earnings Per Share and Per Unit
 
Basic earnings per share of the Company is computed by dividing net income available for common stockholders by the weighted Common Shares outstanding - basic. Diluted earnings per share is computed by dividing net income available to common stockholders plus noncontrolling interests in the Operating Partnership by the weighted Common Shares outstanding - basic plus the dilutive effect of options, warrants and convertible securities outstanding, including Common Units, using the treasury stock method. Weighted Common Shares outstanding - basic includes all unvested restricted stock where dividends received on such restricted stock are non-forfeitable.

1.    Description of Business and Significant Accounting Policies – Continued

Basic earnings per unit of the Operating Partnership is computed by dividing net income available for common unitholders by the weighted Common Units outstanding - basic. Diluted earnings per unit is computed by dividing net income available to common unitholders by the weighted Common Units outstanding - basic plus the dilutive effect of options and warrants, using the treasury stock method. Weighted Common Units outstanding - basic includes all of the Company's unvested restricted stock where distributions received on such restricted stock are non-forfeitable.
 
Recently Issued Accounting Standards
 
The Financial Accounting Standards Board (“FASB”) recently issued an accounting standards update (“ASU”) that amended consolidation requirements. The amendments significantly change the consolidation analysis required under GAAP and require companies to reevaluate all previous consolidation conclusions. We adopted the ASU as of January 1, 2016 and there was no impact to consolidated entities included in our Consolidated Financial Statements.
 
The FASB recently issued an ASU that requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability to which they relate, consistent with debt discounts, as opposed to being presented as assets. For debt issuance costs related to revolving credit facilities, the FASB allows the presentation of debt issuance costs as an asset. We adopted the ASU as of January 1, 2016 with retrospective application to our December 31, 2015 Consolidated Balance Sheets. The effect of the adoption was to reclassify debt issuance costs from deferred financing and leasing costs, net of accumulated amortization, as follows: $7.8 million to a contra account as a deduction from the related mortgages and notes payable; and $2.1 million to prepaid expenses and other assets. There was no effect on our Consolidated Statements of Income or Consolidated Statements of Cash Flows.

The FASB recently issued an ASU that requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The ASU is required to be adopted in 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. Our initial analysis of our non-lease related revenue contracts indicates that the adoption of this ASU will not have a material effect on our Consolidated Financial Statements; however, we are still in the process of evaluating this ASU.

The FASB recently issued an ASU that adds to and clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The ASU is required to be adopted in 2018 with retrospective application required. We do not expect such adoption to have a material effect on our Consolidated Statements of Cash Flows.
 
The FASB recently issued an ASU which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The ASU requires lessors to account for leases using an approach that is substantially equivalent to the existing guidance and is effective for reporting periods beginning in 2019 with early adoption permitted. We are in the process of evaluating this ASU.

The FASB recently issued an ASU that requires, among other things, the use of a new current expected credit loss ("CECL") model in determining our allowances for doubtful accounts with respect to accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable. The CECL model requires that we estimate our lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. We will also be required to disclose information about how we developed the allowances, including changes in the factors (e.g., portfolio mix, credit trends, unemployment, gross domestic product, etc.) that influenced our estimate of expected credit losses and the reasons for those changes. We will apply the ASU’s provisions as a cumulative-effect adjustment to retained earnings upon adoption in 2020. We are in the process of evaluating this ASU.

The FASB recently issued an ASU that requires management of all entities to evaluate whether there are conditions and events that raise substantial doubt about the entity's ability to continue as a going concern within one year after the financial statements are issued. We adopted the ASU as of December 31, 2016. We added additional disclosures in Note 6 as a result of the adoption of this ASU.

Acquisitions

During 2016, we acquired a building in Raleigh, which encompasses 243,000 rentable square feet, for a net purchase price of $76.9 million. We expensed $0.3 million of acquisition costs (included in general and administrative expenses) related to this acquisition. The assets acquired and liabilities assumed were recorded at fair value as determined by management, with the assistance of third party specialists, based on information available at the acquisition date and on current assumptions as to future operations.

During 2016, we also acquired:

•
fee simple title to the land underneath one of our buildings in Pittsburgh that was previously subject to a ground lease for a purchase price of $18.5 million. We expensed $0.5 million of acquisition costs (included in general and administrative expenses) related to this acquisition;

•
an acre of development land in Raleigh for a purchase price, including capitalized acquisition costs, of $5.8 million; and

•
14 acres of development land in Nashville for a purchase price, including capitalized acquisition costs, of $9.1 million.

During 2014, we acquired:

•
a building in Orlando encompassing 246,000 rentable square feet for a purchase price of $67.4 million;

•
our partner's 50.0% interest in a building owned by our consolidated Highwoods-Markel Associates, LLC joint venture in Richmond encompassing 66,000 rentable square feet for a purchase price of $4.2 million, which is recorded as acquisition of noncontrolling interest in consolidated affiliate;

•
land in Nashville for a purchase price and related transaction costs of $15.8 million (including contingent consideration of $3.3 million); and

•
a building in Raleigh encompassing 374,000 rentable square feet for a purchase price of $83.8 million.

We expensed $0.5 million of acquisition costs (included in general and administrative expenses) in 2014 related to these acquisitions. The assets acquired and liabilities assumed were recorded at fair value as determined by management, with the assistance of third party specialists, based on information available at the acquisition date and on current assumptions as to future operations.

Dispositions

During 2016, we sold:

•
substantially all of our wholly-owned Country Club Plaza assets in Kansas City (which we refer to as the “Plaza assets”) for a sale price of $660.0 million (before closing credits to buyer of $4.8 million). We recorded gains on disposition of discontinued operations of $414.5 million and a gain on disposition of property of $1.3 million related to the land; and
 
•
a 32,000 square foot building for a sale price of $4.7 million (before closing credits to buyer of $0.1 million) and recorded a gain on disposition of property of $1.1 million. The buyer, which leased 79% of the building, is a family business controlled by a director of the Company. The sale price exceeded the value set forth in an appraisal performed by a reputable independent commercial real estate services firm that has no relationship with the director or any of his affiliates.

During 2016, we also sold two buildings and various land parcels for an aggregate sale price of $31.1 million (before closing credits to buyer of $0.5 million) and recorded aggregate gains on disposition of property of $12.4 million. We deferred $0.4 million of gain related to a land sale for a portion of the sale price that was escrowed for contingent future infrastructure work.


2.     Real Estate Assets - Continued

During 2015, we sold a total of three buildings and various land parcels for an aggregate sale price of $27.8 million and recorded aggregate gains on disposition of property of $9.2 million, net of $0.5 million in taxes payable by our taxable REIT subsidiary.

During 2014, we sold a total of 33 buildings and various land parcels for an aggregate sale price of $187.3 million (before closing credits to buyer of $8.6 million for unfunded building and tenant improvements and $2.9 million for free rent) and recorded aggregate gains on disposition of property of $44.4 million.

Impairments

During 2014, we recorded an impairment of real estate assets of $0.6 million on a building in Greensboro. This impairment was due to a change in the assumed timing of future disposition and leasing assumptions, which reduced the future expected cash flows from the impaired property.

Mortgages and Notes Receivable

Mortgages and notes receivable were $8.8 million and $2.1 million at December 31, 2016 and 2015, respectively.

During 2010, we provided seller financing in conjunction with two disposition transactions. We accounted for these dispositions using the installment method, whereby a gain on disposition of property was deferred until the seller financing was repaid. During 2014, the $16.5 million of seller financing was fully repaid and the resultant $0.4 million gain on disposition of property was recorded.

During 2012, we provided $8.6 million of secured acquisition financing to a third party. We also agreed to loan such third party $8.4 million on a secured basis to fund future infrastructure development. During 2015, $9.9 million of the secured acquisition financing was repaid, including accrued interest. Previously, we concluded this arrangement to be an interest in a variable interest entity. However, since we did not have the power to direct matters that most significantly impact the activities of the entity, we did not qualify as the primary beneficiary. Accordingly, the entity was not consolidated. Our risk of loss with respect to this arrangement was limited to the carrying value of the mortgage receivable.

We evaluate the ability to collect our mortgages and notes receivable by monitoring the leasing statistics and/or market fundamentals of these assets. As of December 31, 2016, our mortgages and notes receivable were not in default and there were no other indicators of impairment.

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

- Concourse Center Associates, LLC ("Concourse")

During 2016, Concourse (a joint venture in which we owned a 50.0% interest) sold two buildings and land to an unrelated third party for an aggregate sale price of $11.0 million and recorded losses on disposition of property of $0.1 million. As our cost basis was different from the basis reflected at the joint venture level, we recorded $0.4 million of gains through equity in earnings of unconsolidated affiliates. Simultaneously with the sale, the joint venture repaid all $6.6 million of its debt.

4.    Investments in and Advances to Affiliates – Continued

- Highwoods DLF 97/26 DLF 99/32, LP (“DLF II”)
 
During 2015, DLF II sold a building to an unrelated third party for a sale price of $7.0 million and recorded a gain on disposition of property of $2.1 million. We recorded $1.1 million as our share of this gain through equity in earnings of unconsolidated affiliates.

- Kessinger/Hunter & Company, LC ("Kessinger/Hunter")
 
Kessinger/Hunter, which is managed by our joint venture partner, provides leasing services, among other things, to certain buildings that we currently own and/or previously owned in Kansas City in exchange for customary fees from us. Kessinger/Hunter received $0.4 million, $0.3 million and $0.6 million from us for these services in 2016, 2015 and 2014, respectively.
 
- Highwoods DLF 98/29, LLC (“DLF I”)

See Note 2 for a description of our acquisition of a building in Orlando from DLF I during 2015. The joint venture recorded a gain on disposition of property of $13.7 million. Our share of $3.1 million was recorded as a reduction to real estate assets.

During 2014, DLF I sold a building to an unrelated third party for a sale price of $13.7 million (before $0.4 million in closing credits to buyer for free rent) and recorded a gain on disposition of property of $1.0 million. We recorded $0.2 million as our share of this gain through equity in earnings of unconsolidated affiliates.

- 4600 Madison Associates, LP ("4600 Madison")

During 2016, 4600 Madison (a joint venture in which we owned a 12.5% interest) sold a building and land in separate transactions to unrelated third parties for an aggregate sale price of $36.1 million and recorded gains on disposition of property of $22.3 million. As our cost basis was different from the basis reflected at the joint venture level, we recorded $1.9 million of gains through equity in earnings of unconsolidated affiliates. Simultaneously with the sales, the joint venture repaid all $9.7 million of its debt.

- Board of Trade Investment Company ("Board of Trade")

During 2014, Board of Trade (a joint venture in which we owned a 49.0% interest) sold a building to an unrelated third party for gross proceeds of $8.3 million and recorded a gain of $1.9 million. As our cost basis was different from the basis reflected at the entity level, we recorded a net impairment charge on our investment of $0.4 million. This charge represented the other-than-temporary decline in the fair value below the carrying value of our investment. Our interest in Board of Trade was redeemed in exchange for $4.7 million in cash.

- Highwoods KC Glenridge Office, LLC ("KC Glenridge Office") and Highwoods KC Glenridge Land, LLC ("KC Glenridge Land")

During 2015, KC Glenridge Office (a joint venture in which we owned a 40.0% interest) and KC Glenridge Land (a joint venture in which we owned a 39.9% interest) collectively sold two buildings and land to an unrelated third party for an aggregate sale price of $24.5 million (before closing credits to buyer of $0.3 million for unfunded tenant improvements) and recorded gains on disposition of property of $2.4 million. We recorded $0.9 million as our share of these gains through equity in earnings of unconsolidated affiliates.

During 2014, KC Glenridge Office paid at maturity the remaining $14.9 million balance on a secured mortgage loan with an effective interest rate of 4.84%.

- Other Activities
 
We receive development, management and leasing fees for services provided to certain of our joint ventures. These fees are recognized in income to the extent of our respective joint venture partner's interest. During the years ended December 31, 2016, 2015 and 2014, we recognized $0.8 million, $1.4 million and $1.2 million, respectively, of development/construction, management and leasing fees from our unconsolidated joint ventures. At both December 31, 2016 and 2015, we had receivables of $0.1 million related to these fees in accounts receivable.
 
Consolidated Affiliates
 
The following summarizes our consolidated affiliates:

- Highwoods-Markel Associates, LLC (“Markel”)

We have a 50.0% ownership interest in Markel. We are the manager and leasing agent for Markel's properties, which are located in Richmond in exchange for customary management and leasing fees. We consolidate Markel since we are the managing member and control the major operating and financial policies of the entity. As controlling member, we have an obligation to cause this property-owning entity to distribute proceeds of liquidation to the noncontrolling interest member in these partially owned properties only if the net proceeds received by the entity from the sale of any of Markel's assets warrant a distribution as determined by the agreement governing the joint venture. We estimate the value of such noncontrolling interest distributions would have been $24.8 million had the entity been liquidated at December 31, 2016. This estimated settlement value is based on the fair value of the underlying properties which is based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates and costs to operate each property. If the entity's underlying assets are worth less than the underlying liabilities on the date of such liquidation, we would have no obligation to remit any consideration to the noncontrolling interest holder.

See Note 2 for a description of our acquisition of the noncontrolling member's 50.0% interest in a building owned by Markel during 2014.

- Harborview
 
We had a 20.0% interest in Harborview, which had been accounted for as a financing obligation since our partner had the right to put its 80.0% equity interest back to us any time prior to September 11, 2015. During 2012, we also provided a three-year $20.8 million interest-only secured loan to Harborview that was scheduled to mature in September 2015.

During the second quarter of 2015, as a result of our partner’s irrevocable exercise of a buy-sell provision in our Harborview joint venture agreement, our partner’s right to put its 80.0% equity interest back to us became no longer exercisable, which resulted in recording the original contribution transaction as a partial sale. As a result, we were required to begin accounting for Harborview using the equity method of accounting. See Note 1.

During the third quarter of 2015, we sold our 20.0% interest in Harborview to our partner for net proceeds of $6.9 million and recorded a $4.2 million gain on disposition of investment in unconsolidated affiliate. The $20.8 million interest-only secured loan previously provided by us to Harborview was paid in full upon consummation of the sale.

Our $475.0 million unsecured revolving credit facility is scheduled to mature in January 2018 and includes an accordion feature that allows for an additional $75.0 million of borrowing capacity subject to additional lender commitments. Assuming no defaults have occurred, we have an option to extend the maturity for two additional six-month periods. The interest rate at our current credit ratings is LIBOR plus 110 basis points and the annual facility fee is 20 basis points. There were no amounts outstanding under our revolving credit facility at December 31, 2016 and $48.8 million outstanding at January 27, 2017. At both December 31, 2016 and January 27, 2017, 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, 2016 and January 27, 2017 was $474.8 million and $426.0 million, respectively.

During 2016, we prepaid without penalty the remaining $43.6 million balance on a secured mortgage loan with an effective interest rate of 7.5% that was originally scheduled to mature in August 2016. Real estate assets having a gross book value of approximately $73 million became unencumbered in connection with the payoff of this secured loan. We also paid down $2.4 million of secured loan balances through principal amortization during 2016.

During 2016, we borrowed an aggregate of $150.0 million under an unsecured bank term loan that is originally scheduled to mature in January 2022. The interest rate on the term loan at our current credit ratings is LIBOR plus 110 basis points.

During 2015, we prepaid without penalty a secured mortgage loan with a fair market value of $5.9 million with an effective interest rate of 7.65% that was originally scheduled to mature in February 2016, the remaining $106.0 million balance on a secured mortgage loan with an effective interest rate of 6.88% that was originally scheduled to mature in January 2016 and the remaining $39.4 million balance on a secured mortgage loan with an effective interest rate of 6.43% that was originally scheduled to mature in November 2015. We recorded aggregate losses on debt extinguishment of $0.2 million related to these prepayments.

During 2015, we obtained a $350.0 million, six-month unsecured bridge facility. The interest rate on the bridge facility at our current credit ratings was LIBOR plus 110 basis points. There was $350.0 million outstanding under our bridge facility at December 31, 2015. During 2016, we prepaid without penalty the full balance on this unsecured bridge facility.
 
6.    Mortgages and Notes Payable - Continued
 
During 2015, we amended our $225.0 million, seven-year unsecured bank term loan, which was scheduled to mature in January 2019. We increased the borrowed amount to $350.0 million. The amended term loan is now scheduled to mature in June 2020 and the interest rate, based on our current credit ratings, was reduced from LIBOR plus 175 basis points to LIBOR plus 110 basis points. We incurred $1.3 million of debt issuance costs in connection with this amendment, which will be amortized along with existing unamortized debt issuance costs over the remaining term of the new loan.
 
During 2015, we acquired our joint venture partner’s 77.2% interest in a building in Orlando. Simultaneously with this acquisition, the joint venture's previously existing mortgage note was restructured into a new $18.0 million first mortgage note and a $10.2 million subordinated note, both of which are scheduled to mature in July 2017. Assuming no defaults have occurred, we have an option to extend the maturity for an additional year. The first mortgage note is interest only with an effective interest rate of 5.36%, payable monthly. The subordinated note has an effective interest rate of 8.6%. Additionally, we deposited $3.0 million into escrow to fund tenant improvements, leasing commissions and building improvements. The first mortgage note and subordinated note can now be prepaid at any time upon a sale or refinancing of the property. In such event, the subordinated note and any and all accrued interest thereon would be deemed fully satisfied upon payment of a "waterfall payment," if any. Such "waterfall payment" would be a cash payment equal to 50.0% of the amount, if any, by which the net sale proceeds or appraised value in the event of a refinancing exceeds (1) the outstanding principal of the first mortgage note, (2) the funds deposited by us into escrow to fund tenant improvements, leasing commissions and building improvements and (3) a 10.0% return on such funds deposited by us into escrow. As of the date of such restructuring, the fair value of the first mortgage note was $18.3 million and the fair value of the subordinated note equaled the projected waterfall payment of $1.0 million.
 
During 2014, the Operating Partnership issued $300 million aggregate principal amount of 3.20% Notes due June 15, 2021, less original issue discount of $3.1 million. These notes were priced at 98.983% for an effective yield of 3.363%. Underwriting fees and other expenses were incurred that aggregated $2.4 million; these costs were deferred and will be amortized over the term of the notes.
 
During 2014, we prepaid the remaining $36.9 million balance on a secured mortgage loan with an effective interest rate of 3.34% that was originally scheduled to mature in April 2015. We recorded $0.3 million of loss on debt extinguishment related to this prepayment. We also prepaid without penalty the remaining $123.7 million balance on a secured mortgage loan with an effective interest rate of 3.11% that was originally scheduled to mature in July 2014 and the remaining $7.2 million balance on a secured mortgage loan with an effective interest rate of 3.32% that was originally scheduled to mature in August 2014. We recorded less than $0.1 million of gain on debt extinguishment related to this last prepayment.
 
We are currently in compliance with financial covenants and other requirements with respect to our consolidated debt.
 
Our revolving credit facility and bank term loans require us to comply with customary operating covenants and various financial requirements. Upon an event of default on the revolving credit facility, the lenders having at least 51.0% of the total commitments under the revolving credit facility can accelerate all borrowings then outstanding, and we could be prohibited from borrowing any further amounts under our revolving credit facility, which would adversely affect our ability to fund our operations. In addition, certain of our unsecured debt agreements contain cross-default provisions giving the unsecured lenders the right to declare a default if we are in default under more than $25.0 million with respect to other loans in some circumstances.
 
The Operating Partnership has $379.7 million carrying amount of 2017 notes outstanding, $200.0 million carrying amount of 2018 notes outstanding, $298.1 million carrying amount of 2021 notes outstanding and $248.4 million carrying amount of 2023 notes 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 any series of notes can accelerate the principal amount of such series upon written notice of a default that remains uncured after 60 days.
 

6.    Mortgages and Notes Payable - Continued
 
We have considered our short-term (one year or less) liquidity needs and the adequacy of our estimated cash flows from operating activities and other expected financing sources to meet these needs. In particular, we have considered our scheduled debt maturities in 2017, including $379.7 million principal amount of unsecured notes due March 15, 2017 and the $109.1 million secured loan due November 1, 2017. We expect to meet these short-term liquidity requirements, including the repayment of such unsecured notes and secured loan, through a combination of the following:
 
•
available cash and cash equivalents;
 
•
cash flows from operating activities;
 
•
issuance of debt securities by the Operating Partnership (some of which debt securities may be hedged to a fixed interest rate pursuant to the forward-starting swaps discussed below);
 
•
issuance of secured debt (including the anticipated $100.0 million fixed-rate loan discussed below);
 
•
bank term loans (including the anticipated $50.0 million expansion of an existing term loan);
 
•
borrowings under our revolving credit facility;
 
•
issuance of other secured debt;
 
•
issuance of equity securities by the Company or the Operating Partnership; and
 
•
the disposition of non-core assets.
 
To limit the risks associated with interest rate changes, during 2016, we obtained $150.0 million notional amount of forward-starting swaps that expire on March 15, 2017 and effectively lock the underlying 10-year treasury rate at 1.90% with respect to a planned issuance of debt securities by the Operating Partnership.
 
We expect to obtain an approximate $100.0 million fixed-rate secured loan with a term of at least 10 years. This planned secured loan is expected to close no later than May 1, 2017, which is the date on which we can prepay without penalty the $109.1 million secured loan that is scheduled to mature on November 1, 2017. The new secured loan is subject to formal lender commitment, definitive documentation and customary conditions.
 
We expect to borrow an additional $50.0 million under the unsecured bank term loan we obtained in 2016 that is scheduled to mature in January 2022. This planned expansion of the term loan, which will bear interest at LIBOR plus 110 basis points based on our current credit ratings, is expected to close no later than March 31, 2017.

Derivative Financial Instruments

During 2016, we obtained $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 1.90% with respect to a forecasted debt issuance expected to occur prior to March 15, 2017.

We also have six floating-to-fixed interest rate swaps through January 2019 each with respect to an aggregate of $225.0 million LIBOR-based borrowings. These swaps effectively fix the underlying LIBOR rate at a weighted average of 1.678%. The swap agreements contain a provision whereby if we default on more than $25.0 million of indebtedness and which default results in repayment of such indebtedness being, or becoming capable of being, accelerated by the lender, then we could also be declared in default on our swaps.

The counterparties under these swaps are major financial institutions. Our interest rate swaps have been designated as and are being accounted for as cash flow hedges with changes in fair value recorded in other comprehensive income/(loss) each reporting period. No gain or loss was recognized related to hedge ineffectiveness or to amounts excluded from effectiveness testing on our cash flow hedges during the years ended December 31, 2016 and 2015. We have no collateral requirements related to our interest rate swaps.

Amounts reported in accumulated other comprehensive income/(loss) related to derivatives will be reclassified to interest expense as interest payments are made on our variable rate debt. During 2017, we estimate that $2.3 million will be reclassified to interest expense.

In connection with tax increment financing for a parking garage we constructed in 1999, we were obligated to pay fixed special assessments over a 20-year period ending in 2019. The net present value of these assessments, discounted at the 6.93% interest rate on the underlying tax increment financing, was recorded as a financing obligation and $7.4 million was classified in liabilities held for sale on our Consolidated Balance Sheets at December 31, 2015.

Lease and contractual commitments represent commitments under signed leases and contracts for operating properties (excluding tenant-funded tenant improvements) and contracts for development/redevelopment projects, of which $73.6 million was recorded on our Consolidated Balance Sheets at December 31, 2016.
 
Contingent Consideration
 
In 2015, we acquired development land in Atlanta for a purchase price and related transaction costs of $5.2 million, which includes contingent consideration estimated to be $0.9 million. The contingent consideration is payable in cash to a third party 30 days subsequent to stabilization, which is projected to be in the second quarter of 2019, if and to the extent the stabilized value of the building constructed on the development site exceeds the total development cost.
 
In 2014, we acquired development land in Nashville for a purchase price and related transaction costs of $15.8 million, which includes contingent consideration estimated to be $3.3 million. The contingent consideration is payable in cash to a third party no later than the first quarter of 2020 if and to the extent the stabilized value of the building constructed on the development site exceeds the total development cost.
 
Environmental Matters
 
Substantially all of our in-service and development properties have been subjected to Phase I environmental assessments and, in certain instances, Phase II environmental assessments. Such assessments and/or updates have not revealed, nor are we aware of, any environmental liability that we believe would have a material adverse effect on our Consolidated Financial Statements.
 
Litigation, Claims and Assessments
 
We are from time to time a party to a variety of legal proceedings, claims and assessments arising in the ordinary course of our business. We regularly assess the liabilities and contingencies in connection with these matters based on the latest information available. For those matters where it is probable that we have incurred or will incur a loss and the loss or range of loss can be reasonably estimated, the estimated loss is accrued and charged to income in our Consolidated Financial Statements. In other instances, because of the uncertainties related to both the probable outcome and amount or range of loss, a reasonable estimate of liability, if any, cannot be made. Based on the current expected outcome of such matters, none of these proceedings, claims or assessments is expected to have a material effect on our business, financial condition, results of operations or cash flows.

Noncontrolling Interests

Noncontrolling Interests in Consolidated Affiliates

At December 31, 2016, our noncontrolling interests in consolidated affiliates relate to our joint venture partner's 50.0% interest in office properties in Richmond. Our joint venture partner is an unrelated third party.

Noncontrolling Interests in the Operating Partnership

Noncontrolling interests in the Operating Partnership relate to the ownership of Redeemable Common Units. Net income attributable to noncontrolling interests in the Operating Partnership is computed by applying the weighted average percentage of Redeemable Common Units during the period, as a percent of the total number of outstanding Common Units, to the Operating Partnership’s net income for the period after deducting distributions on Preferred Units. When a noncontrolling unitholder redeems a Common Unit for a share of Common Stock or cash, the noncontrolling interests in the Operating Partnership are reduced and the Company’s share in the Operating Partnership is increased by the fair value of each security at the time of redemption.

Fair Value Disclosures [Abstract]  
Disclosure About Fair Value of Financial Instruments
Disclosure About Fair Value of Financial Instruments

The following summarizes the three levels of inputs that we use to measure fair value.

Level 1. Quoted prices in active markets for identical assets or liabilities.

Our Level 1 asset is our investment in marketable securities that we use to pay benefits under our non-qualified deferred compensation plan. Our Level 1 liability is our non-qualified deferred compensation obligation. The Company's Level 1 noncontrolling interests in the Operating Partnership relate to the ownership of Common Units by various individuals and entities other than the Company.

Level 2. Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.

Our Level 2 assets include the fair value of our mortgages and notes receivable and certain of our interest rate swaps. Our Level 2 liabilities include the fair value of our mortgages and notes payable and the remainder of our interest rate swaps.

The fair value of mortgages and notes receivable and mortgages and notes payable is estimated by the income approach utilizing contractual cash flows and market-based interest rates to approximate the price that would be paid in an orderly transaction between market participants. The fair value of interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments of interest rate swaps are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves. In addition, credit valuation adjustments are considered in the fair values to account for potential nonperformance risk, but were concluded to not be significant inputs to the calculation for the periods presented.
 
Level 3. Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
 
Our Level 3 asset consisted of our tax increment financing bond, which was not routinely traded but whose fair value was determined by the income approach utilizing contractual cash flows and market-based interest rates to estimate the projected redemption value based on quoted bid/ask prices for similar unrated municipal bonds.
 
Our Level 3 liability consisted of the fair value of our financing obligation, which was estimated by the income approach to approximate the price that would be paid in an orderly transaction between market participants, utilizing: (1) contractual cash flows; (2) market-based interest rates; and (3) a number of other assumptions including demand for space, competition for customers, changes in market rental rates, costs of operation and expected ownership periods.

Redeemable Common Units
 
Generally, the Operating Partnership is obligated to redeem each Redeemable Common Unit at the request of the holder thereof for cash equal to the value of one share of Common Stock based on the average of the market price for the 10 trading days immediately preceding the notice date of such redemption, provided that the Company, at its option, may elect to acquire any such Redeemable Common Unit presented for redemption for cash or one share of Common Stock. When a holder redeems a Redeemable Common Unit for a share of Common Stock or cash, the Company’s share in the Operating Partnership will be increased.

Officer, Management and Director Compensation Programs
 
The officers of the Company participate in an annual non-equity incentive program pursuant to which they are eligible to earn cash payments based on a percentage of their annual base salary in effect for December of the applicable year. Under this component of our executive compensation program, officers are eligible to earn additional cash compensation to the extent specific performance-based metrics are achieved during the most recently completed year. The position held by each officer has a target annual incentive percentage that ranges from 35% to 130% of base salary. The more senior the position, the greater the portion of compensation that varies with performance.
 
The percentage amount an officer may earn under the annual non-equity incentive plan is the product of the target annual incentive percentage times an “actual performance factor,” which can range from zero to 200%. The actual performance factor depends upon the relationship between actual performance in specific areas at each of our divisions and predetermined goals. For corporate officers, the actual performance factor is based on the goals and criteria applied to the Company’s performance as a whole. For officers who oversee our divisions, the actual performance factor is based on the goals and criteria applied partly to that division’s performance and partly to the Company’s performance overall. Amounts under our annual non-equity incentive plan are accrued and expensed in the year earned, but are typically paid early in the succeeding year.
 
Certain other employees participate in a similar annual non-equity incentive program. Incentive eligibility ranges from 6% to 30% of annual base salary. The actual incentive payment is determined by a mix of the Company's overall performance, the performance of any applicable division and the individual’s performance during each year. These amounts are also accrued and expensed in the year earned, but are typically paid early in the succeeding year.
 
The Company's officers generally receive annual grants of stock options and restricted stock under the Company's long-term equity incentive plan on or about March 1 of each year. Restricted stock grants are also made annually to directors and certain other employees. Dividends received on restricted stock are non-forfeitable and are paid at the same rate and on the same date as on shares of Common Stock, except that, with respect to shares of total return-based restricted stock issued to the Company's chief executive officer, dividends accumulate and are payable only if and to the extent the shares vest. Dividends paid on subsequently forfeited shares are expensed. Additional shares of total return-based restricted stock may be issued at the end of the applicable measurement periods if and to the extent actual performance exceeds certain levels of performance. Such additional shares, if any, would be fully vested when issued. No expense is recorded for additional shares of total return-based restricted stock that may be issued at the end of the applicable measurement period since that possibility is reflected in the grant date fair value. The following table sets forth the number of shares of Common Stock reserved for future issuance under the Company's long-term equity incentive plans:

Of the possible future issuance under the Company' long-term equity incentive plans at December 31, 2016, no more than an additional 1.0 million shares can be in the form of restricted stock.

During the years ended December 31, 2016, 2015 and 2014, we recognized $6.3 million, $6.9 million and $6.9 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, 2016, there was $5.1 million of total unrecognized share-based compensation costs, which will be recognized over a weighted average remaining contractual term of 2.2 years.

The value of all options as of the date of grant is calculated using the Black-Scholes option-pricing model and is amortized over the respective vesting period or the service period, if shorter, for employees who are or will become eligible under the Company's retirement plan. The weighted average fair values of options granted during 2016, 2015 and 2014 were $4.61, $6.19 and $6.75, respectively, per option. The fair values of the options granted were determined at the grant dates using the following assumptions:

Cash received or receivable from options exercised was $13.4 million, $3.3 million and $11.1 million for the years ended December 31, 2016, 2015 and 2014, respectively. The total intrinsic value of options exercised during the years ended December 31, 2016, 2015 and 2014 was $4.8 million, $0.9 million and $5.0 million, respectively. The total intrinsic value of options outstanding at December 31, 2016, 2015 and 2014 was $5.1 million, $4.3 million and $5.4 million, respectively. The Company generally does not permit the net cash settlement of exercised stock options, but does permit net share settlement so long as the shares received are held for at least a year. The Company has a practice of issuing new shares to satisfy stock option exercises.

- Time-Based Restricted Stock

Shares of time-based restricted stock vest ratably on an annual basis over four years. The value of grants of time-based restricted stock is based on the market value of Common Stock as of the date of grant and is amortized to expense over the respective vesting period or the service period, if shorter, for employees who are or will become eligible under the Company's retirement plan.

- Total Return-Based Restricted Stock
 
Shares of total return-based restricted stock vest to the extent the Company's absolute total returns for certain pre-determined three-year periods exceed predetermined goals. The amount subject to vesting ranges from zero to 150%. Notwithstanding the Company’s absolute total return, if the Company’s total return exceeds 100% of the peer group total return index, at least 75% of total return-based restricted stock issued will vest at the end of the applicable period. The weighted average grant date fair value of such shares of total return-based restricted stock issued in 2016, 2015 and 2014 was determined to be $41.37, $43.77 and $35.58, respectively, and is amortized over the respective three-year period or the service period, if shorter, for employees who are or will become eligible under the Company's retirement plan.

Employee Benefit Plans - Continued

401(k) Retirement Savings Plan
 
We have a 401(k) Retirement Savings Plan covering substantially all employees who meet certain age and employment criteria. We contribute amounts for each participant at a rate of 75% of the employee’s contribution (up to 6% of each employee’s bi-weekly salary and cash incentives, subject to statutory limits). During the years ended December 31, 2016, 2015 and 2014, we contributed $1.3 million, $1.3 million and $1.2 million, respectively, to the 401(k) savings plan. The assets of this qualified plan are not included in our Consolidated Financial Statements since the assets are not owned by us.

Retirement Plan

The Company has a retirement plan for employees with at least 30 years of continuous service or are at least 55 years old with at least 10 years of continuous service. Subject to advance written notice and a non-compete agreement, eligible retirees would be entitled to receive a pro rata amount of the annual non-equity incentive compensation earned during the year of retirement and stock options and time-based restricted stock would be non-forfeitable and vest according to the terms of their original grants. Eligible retirees would also be entitled to retain any total return-based restricted stock that subsequently vests after the retirement date according to the terms of their original grants. For employees who meet the age and service eligibility requirements, 100% of their annual grants are expensed at the grant date as if fully vested. For employees who will meet the age and service eligibility requirements within the normal vesting periods, the grants are amortized over the shorter service period.

Deferred Compensation

Prior to 2010, officers could elect to defer all or a portion of their cash compensation, which was then invested in unrelated mutual funds under our non-qualified deferred compensation plan. These investments are recorded at fair value, which aggregated $2.5 million and $2.7 million at December 31, 2016 and 2015, respectively, and are included in prepaid expenses and other assets, with an offsetting deferred compensation liability recorded in accounts payable, accrued expenses and other liabilities. Deferred amounts ultimately payable to the participants are based on the value of the related mutual fund investments. Accordingly, changes in the value of the unrelated mutual funds are recorded in interest and other income and the corresponding offsetting changes in the deferred compensation liability are recorded in general and administration expense. As a result, there is no effect on our net income.

The following table sets forth our deferred compensation liability:

Employee Stock Purchase Plan

The Company has an Employee Stock Purchase Plan ("ESPP") pursuant to which employees may contribute up to 25% of their cash compensation for the purchase of Common Stock. At the end of each quarterly offering period, each participant's account balance, which includes any and all accumulated dividends, is applied to acquire shares of Common Stock at a cost that is calculated at 85% of the average closing price on the New York Stock Exchange on the five consecutive days preceding the last day of the quarter. In the years ended December 31, 2016, 2015 and 2014, the Company issued 27,773, 29,496 and 28,682 shares, respectively, of Common Stock under this Plan. The 15% discount on newly issued shares, which is taxable income to the participants and is recorded by us as additional compensation expense, aggregated $0.2 million in each of the years ended December 31, 2016, 2015 and 2014. As a general rule, shares purchased under the Plan must be held for at least a year. The Company satisfies its ESPP obligations by issuing additional shares of Common Stock.

Income Tax Disclosure [Abstract]  
Income Taxes
Income Taxes

Our Consolidated Financial Statements include the operations of the Company's taxable REIT subsidiary, which is not entitled to the dividends paid deduction and is subject to federal, state and local income taxes on its taxable income. As a REIT, the Company may also be subject to federal excise taxes if it engages in certain types of transactions.

The minimum dividend per share of Common Stock required for the Company to maintain its REIT status was $0.99, $1.31 and $1.13 per share in 2016, 2015 and 2014, respectively. Continued qualification as a REIT depends on the Company's ability to satisfy the dividend distribution tests, stock ownership requirements and various other qualification tests. The tax basis of the Company's assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $4.0 billion and $2.3 billion, respectively, at December 31, 2016 and $4.2 billion and $2.6 billion, respectively, at December 31, 2015. The tax basis of the Operating Partnership's assets (net of accumulated tax depreciation and amortization) and liabilities was approximately $4.0 billion and $2.3 billion, respectively, at December 31, 2016 and $4.2 billion and $2.6 billion, respectively, at December 31, 2015.

During the years ended December 31, 2016, 2015 and 2014, the Company qualified as a REIT and incurred no federal income tax expense; accordingly, the only federal income taxes included in the accompanying Consolidated Financial Statements relate to activities of the Company's taxable REIT subsidiary.

The following table sets forth the Company's income tax expense/(benefit):

The Company's net deferred tax liability was $0.1 million and $0.2 million as of December 31, 2016 and 2015, respectively. The net deferred tax liability is comprised primarily of tax versus book differences related to property (depreciation, amortization and basis differences).

For the years ended December 31, 2016 and 2015, there were no unrecognized tax benefits. The Company is subject to federal, state and local income tax examinations by taxing authorities for 2013 through 2016. The Company does not expect that the total amount of unrecognized benefits will materially change within the next year.

Segment Reporting [Abstract]  
Segment Information
Segment Information

Our principal business is the operation, acquisition and development of rental real estate properties. We evaluate our business by product type and by geographic location. Each product type has different customers and economic characteristics as to rental rates and terms, cost per rentable square foot of buildings, the purposes for which customers use the space, the degree of maintenance and customer support required and customer dependency on different economic drivers, among others. The operating results by geographic grouping are also regularly reviewed by our chief operating decision maker for assessing performance and other purposes. There are no material inter-segment transactions.

Our accounting policies of the segments are the same as those used in our Consolidated Financial Statements. All operations are within the United States.

The following tables summarize the rental and other revenues and net operating income, the primary industry property-level performance metric used by our chief operating decision maker which is defined as rental and other revenues less rental property and other expenses, for each of our reportable segments. Our segment information for the year ended December 31, 2014 has been retrospectively revised from previously reported amounts to reflect a change in our reportable segments.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Presentation
Basis of Presentation

Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Our Consolidated Statements of Income for the year ended December 31, 2014 were retrospectively revised from previously reported amounts to reclassify the operations for those properties classified as discontinued operations.

The Company's Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership's Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. We consolidate joint venture investments, such as interests in partnerships and limited liability companies, when we control the major operating and financial policies of the investment through majority ownership, in our capacity as a general partner or managing member or through some other contractual right. At December 31, 2016, three properties owned through a joint venture investment were consolidated.

In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. During 2015, we acquired three buildings and a land parcel using special purpose entities owned by qualified intermediaries to facilitate a potential Section 1031 reverse exchange under the Internal Revenue Code. We determined that these entities were variable interest entities of which we were the primary beneficiary; therefore, we consolidated these entities as of December 31, 2015. At such time, these variable interest entities had total assets, liabilities and cash flows of $421.3 million, $16.3 million, and $7.1 million, respectively. During 2016, we subsequently acquired such special purpose entities and therefore own direct title to these buildings.

All intercompany transactions and accounts have been eliminated.

1.    Description of Business and Significant Accounting Policies – Continued

During 2015, as a result of our partner’s irrevocable exercise of a buy-sell provision in our SF-HIW Harborview Plaza, LP ("Harborview") joint venture agreement, our partner’s right to put its 80.0% equity interest back to us became no longer exercisable. As a result, we recorded the original contribution transaction as a partial sale. Our investment in this joint venture then qualified for the equity method of accounting, which resulted in the retrospective revision of our Consolidated Balance Sheets and Consolidated Statements of Equity and Capital for prior periods.
Use of Estimates
Use of Estimates

The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
Real Estate and Related Assets
Real Estate and Related Assets

Real estate and related assets are recorded at cost and stated at cost less accumulated depreciation. Renovations, replacements and other expenditures that improve or extend the life of assets are capitalized and depreciated over their estimated useful lives. Expenditures for ordinary maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful life of 40 years for buildings and depreciable land infrastructure costs, 15 years for building improvements and five to seven years for furniture, fixtures and equipment. Tenant improvements are amortized using the straight-line method over initial fixed terms of the respective leases, which generally are from three to 10 years. Depreciation expense for real estate assets was $173.1 million, $168.7 million and $154.4 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Expenditures directly related to the development and construction of real estate assets are included in net real estate assets and are stated at depreciated cost. Development expenditures include pre-construction costs essential to the development of properties, development and construction costs, interest costs on qualifying assets, real estate taxes, development personnel salaries and related costs and other costs incurred during the period of development. Interest and other carrying costs are capitalized until the building is ready for its intended use, but not later than a year from cessation of major construction activity. We consider a construction project as substantially completed and ready for its intended use upon the completion of tenant improvements. We cease capitalization on the portion that is substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction.

Expenditures directly related to the leasing of properties are included in deferred leasing costs and are stated at amortized cost. Such expenditures are part of the investment necessary to execute leases and, therefore, are classified as investment activities in the statement of cash flows. All leasing commissions paid to third parties for new leases or lease renewals are capitalized. Internal leasing costs, which consist primarily of compensation, benefits and other costs, such as legal fees related to leasing activities, that are incurred in connection with successfully obtaining leases of properties are also capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases, which generally are from three to 10 years. Estimated costs related to unsuccessful activities are expensed as incurred.

We record liabilities for the performance of asset retirement activities when the obligation to perform such activities is probable even when uncertainty exists about the timing and/or method of settlement.

Upon the acquisition of real estate assets, we assess the fair value of acquired tangible assets such as land, buildings and tenant improvements, intangible assets and liabilities such as above and below market leases, acquired in-place leases, customer relationships and other identifiable intangible assets and assumed liabilities. We assess fair value based on estimated cash flow projections that utilize discount and/or capitalization rates as well as available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. 

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

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

With respect to assets classified as held for use, we perform an impairment analysis if events or changes in circumstances indicate that the carrying value may be impaired, such as a significant decline in occupancy, identification of materially adverse legal or environmental factors, change in our designation of an asset from core to non-core, which may impact the anticipated holding period, or a decline in market value to an amount less than cost. This analysis is generally performed at the property level, except when an asset is part of an interdependent group such as an office park, and consists of determining whether the asset's carrying amount will be recovered from its undiscounted estimated future operating and residual cash flows. These cash flows are estimated based on a number of assumptions that are subject to economic and market uncertainties including, among others, demand for space, competition for customers, changes in market rental rates, costs to operate each property and expected ownership periods. For properties under development, the cash flows are based on expected service potential of the asset or asset group when development is substantially complete.

If the carrying amount of a held for use asset exceeds the sum of its undiscounted future operating and residual cash flows, an impairment loss is recorded for the difference between estimated fair value of the asset and the carrying amount. We generally estimate the fair value of assets held for use by using discounted cash flow analyses. In some instances, appraisal information may be available and is used in addition to a discounted cash flow analysis. As the factors used in generating these cash flows are difficult to predict and are subject to future events that may alter our assumptions, the discounted and/or undiscounted future operating and residual cash flows estimated by us in our impairment analyses or those established by appraisal may not be achieved and we may be required to recognize future impairment losses on properties held for use.
 
We record assets held for sale at the lower of the carrying amount or estimated fair value. Fair value of assets held for sale is equal to the estimated or contracted sales price with a potential buyer, less costs to sell. The impairment loss is the amount by which the carrying amount exceeds the estimated fair value.
 
We also analyze our investments in unconsolidated affiliates for impairment. This analysis consists of determining whether an expected loss in market value of an investment is other than temporary by evaluating the length of time and the extent to which the market value has been less than cost, the financial condition and near-term prospects of the investment, and our intent and ability to retain our investment for a period of time sufficient to allow for any anticipated recovery in market value. As the factors used in this analysis are difficult to predict and are subject to future events that may alter our assumptions, we may be required to recognize future impairment losses on our investments in unconsolidated affiliates.
Sales of Real Estate
Sales of Real Estate
 
For sales transactions meeting the requirements for full profit recognition, the related assets and liabilities are removed from the balance sheet and the resultant gain or loss is recorded in the period the transaction closes. For sales transactions with continuing involvement after the sale, if the continuing involvement with the property is limited by the terms of the sales contract, profit is recognized at the time of sale and is reduced by the maximum exposure to loss related to the nature of the continuing involvement. Sales to entities in which we have or receive an interest are accounted for using partial sale accounting.

For transactions that do not meet the criteria for a sale, we evaluate the nature of the continuing involvement, including put and call provisions, if present, and account for the transaction as a financing arrangement, profit-sharing arrangement, leasing arrangement or other alternate method of accounting, rather than as a sale, based on the nature and extent of the continuing involvement. Some transactions may have numerous forms of continuing involvement. In those cases, we determine which method is most appropriate based on the substance of the transaction.
Rental and Other Revenues
Rental and Other Revenues
 
Minimum contractual rents from leases are recognized on a straight-line basis over the terms of the respective leases. This means that, with respect to a particular lease, actual amounts billed in accordance with the lease during any given period may be higher or lower than the amount of rental revenue recognized for the period. Straight-line rental revenue is commenced when the customer assumes control of the leased premises. Accrued straight-line rents receivable represents the amount by which straight-line rental revenue exceeds rents currently billed in accordance with lease agreements. Contingent rental revenue, such as percentage rent, is accrued when the contingency is removed. Termination fee income is recognized at the later of when the customer has vacated the space or the lease has expired and a fully executed lease termination agreement has been delivered, the amount of the fee is determinable and collectability of the fee is reasonably assured. Rental revenue reductions related to co-tenancy lease provisions, if any, are accrued when events have occurred that trigger such provisions.

Cost recovery income is determined on a calendar year and a lease-by-lease basis. The most common types of cost recovery income in our leases are common area maintenance (“CAM”) and real estate taxes, for which a customer typically pays its pro-rata share of operating and administrative expenses and real estate taxes in excess of the costs incurred during a contractually specified base year. The computation of cost recovery income is complex and involves numerous judgments, including the interpretation of lease provisions. Leases are not uniform in dealing with such cost recovery income and there are many variations in the computation. Many customers make monthly fixed payments of CAM, real estate taxes and other cost reimbursement items. We accrue income related to these payments each month. We make quarterly accrual adjustments, positive or negative, to cost recovery income to adjust the recorded amounts to our best estimate of the final annual amounts to be billed and collected. After the end of the calendar year, we compute each customer's final cost recovery income and, after considering amounts paid by the customer during the year, issue a bill or credit for the appropriate amount to the customer. The differences between the amounts billed less previously received payments and the accrual adjustment are recorded as increases or decreases to cost recovery income when the final bills are prepared, which occurs during the first half of the subsequent year.
Allowance for Doubtful Accounts
Allowance for Doubtful Accounts
 
Accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable are reduced by an allowance for amounts that may become uncollectible in the future. We regularly evaluate the adequacy of our allowance for doubtful accounts. The evaluation primarily consists of reviewing past due account balances and considering such factors as the credit quality of our customer, historical trends of the customer and changes in customer payment terms. Additionally, with respect to customers in bankruptcy, we estimate the probable recovery through bankruptcy claims and adjust the allowance for amounts deemed uncollectible. If our assumptions regarding the collectability of receivables prove incorrect, we could experience losses in excess of our allowance for doubtful accounts. The allowance and its related receivable are written-off when we have concluded there is a low probability of collection and we have discontinued collection efforts.
Discontinued Operations
Discontinued Operations
 
Properties that are sold or classified as held for sale are classified as discontinued operations provided that the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results. Interest expense is included in discontinued operations if a related loan securing the sold property is to be paid off or assumed by the buyer in connection with the sale.
Lease Incentives
Lease Incentives
 
Lease incentive costs, which are payments made to or on behalf of a customer as an incentive to sign a lease, are capitalized in deferred leasing costs and amortized on a straight-line basis over the respective lease terms as a reduction of rental revenues.
Investments in Unconsolidated Affiliates
Investments in Unconsolidated Affiliates
 
We account for our joint venture investments using the equity method of accounting when our interests represent a general partnership interest but substantive participating rights or substantive kick out rights have been granted to the limited partners or when our interests do not represent a general partnership interest and we do not control the major operating and financial policies of the investment. These investments are initially recorded at cost as investments in unconsolidated affiliates and are subsequently adjusted for our share of earnings and cash contributions and distributions. To the extent our cost basis at formation of the joint venture is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related assets and included in our share of equity in earnings of unconsolidated affiliates.
Cash and Cash Equivalent
Cash Equivalents

We consider highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.
Restricted Cash
Restricted Cash
 
Restricted cash represents cash deposits that are legally restricted or held by third parties on our behalf, such as construction-related escrows, property disposition proceeds set aside and designated or intended to fund future tax-deferred exchanges of qualifying real estate investments, escrows and reserves for debt service, real estate taxes and property insurance established pursuant to certain mortgage financing arrangements and any deposits made with lenders to unencumber secured properties.
Redeemable Common Units and Preferred Units
Redeemable Common Units and Preferred Units
 
Limited partners holding Common Units other than the Company (“Redeemable Common Units”) have the right to put any and all of the Common Units to the Operating Partnership and the Company has the right to put any and all of the Preferred Units to the Operating Partnership in exchange for their liquidation preference plus accrued and unpaid distributions in the event of a corresponding redemption by the Company of the underlying Preferred Stock. Consequently, these Redeemable Common Units and Preferred Units are classified outside of permanent partners’ capital in the Operating Partnership's accompanying balance sheets. The recorded value of the Redeemable Common Units is based on fair value at the balance sheet date as measured by the closing price of Common Stock on that date multiplied by the total number of Redeemable Common Units outstanding. The recorded value of the Preferred Units is based on their redemption value.
Income Tax
Income Taxes
 
The Company has elected and expects to continue to qualify as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”). A corporate REIT is a legal entity that holds real estate assets and, through the payment of dividends to stockholders, is generally permitted to reduce or avoid the payment of federal and state income taxes at the corporate level. To maintain qualification as a REIT, the Company is required to pay dividends to its stockholders equal to at least 90.0% of its annual REIT taxable income, excluding net capital gains. The partnership agreement requires the Operating Partnership to pay economically equivalent distributions on outstanding Common Units at the same time that the Company pays dividends on its outstanding Common Stock.

1.    Description of Business and Significant Accounting Policies – Continued

Other than income taxes related to its taxable REIT subsidiary, the Operating Partnership does not reflect any federal income taxes in its financial statements, since as a partnership the taxable effects of its operations are attributed to its partners. The Operating Partnership does record state income tax for states that tax partnership income directly.
 
We conduct certain business activities through a taxable REIT subsidiary, as permitted under the Code. The taxable REIT subsidiary is subject to federal, state and local income taxes on its taxable income. We record provisions for income taxes based on its income recognized for financial statement purposes, including the effects of temporary differences between such income and the amount recognized for tax purposes.
Concentration of Credit Risk
Concentration of Credit Risk
 
At December 31, 2016, properties that we wholly own were leased to 1,741 customers. The geographic locations that comprise greater than 10.0% of our rental and other revenues are Raleigh, Atlanta, Tampa and Nashville. Our customers engage in a wide variety of businesses. No single customer generated more than 6% of our consolidated revenues during 2016.
 
We maintain our cash and cash equivalents and our restricted cash at financial or other intermediary institutions. The combined account balances at each institution may exceed FDIC insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. Additionally, from time to time in connection with tax-deferred 1031 transactions, our restricted cash balances may be commingled with other funds being held by any such intermediary institution, which would subject our balance to the credit risk of the institution.
Derivative Financial Instruments
Derivative Financial Instruments
 
We borrow funds at a combination of fixed and variable rates. Borrowings under our revolving credit facility and bank term loans bear interest at variable rates. Our long-term debt typically bears interest at fixed rates. Our interest rate risk management objectives are to limit generally the impact of interest rate changes on earnings and cash flows and lower our overall borrowing costs. To achieve these objectives, from time to time, we enter into interest rate hedge contracts such as collars, swaps, caps and treasury lock agreements in order to mitigate our interest rate risk with respect to various debt instruments. We generally do not hold or issue these derivative contracts for trading or speculative purposes. The interest rate on all of our variable rate debt is generally adjusted at one or three month intervals, subject to settlements under these interest rate hedge contracts.

Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income/(loss) and is subsequently reclassified into interest expense in the period that the hedged forecasted transaction affects earnings.
 
We account for terminated derivative instruments by recognizing the related accumulated comprehensive income/(loss) balance in current earnings, unless the hedged forecasted transaction continues as originally planned, in which case we continue to amortize the accumulated comprehensive income/(loss) into earnings over the originally designated hedge period.
Earnings Per Share
Earnings Per Share and Per Unit
 
Basic earnings per share of the Company is computed by dividing net income available for common stockholders by the weighted Common Shares outstanding - basic. Diluted earnings per share is computed by dividing net income available to common stockholders plus noncontrolling interests in the Operating Partnership by the weighted Common Shares outstanding - basic plus the dilutive effect of options, warrants and convertible securities outstanding, including Common Units, using the treasury stock method. Weighted Common Shares outstanding - basic includes all unvested restricted stock where dividends received on such restricted stock are non-forfeitable.

1.    Description of Business and Significant Accounting Policies – Continued

Basic earnings per unit of the Operating Partnership is computed by dividing net income available for common unitholders by the weighted Common Units outstanding - basic. Diluted earnings per unit is computed by dividing net income available to common unitholders by the weighted Common Units outstanding - basic plus the dilutive effect of options and warrants, using the treasury stock method. Weighted Common Units outstanding - basic includes all of the Company's unvested restricted stock where distributions received on such restricted stock are non-forfeitable.
Recently Issued Accounting Standards
Recently Issued Accounting Standards
 
The Financial Accounting Standards Board (“FASB”) recently issued an accounting standards update (“ASU”) that amended consolidation requirements. The amendments significantly change the consolidation analysis required under GAAP and require companies to reevaluate all previous consolidation conclusions. We adopted the ASU as of January 1, 2016 and there was no impact to consolidated entities included in our Consolidated Financial Statements.
 
The FASB recently issued an ASU that requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying amount of the debt liability to which they relate, consistent with debt discounts, as opposed to being presented as assets. For debt issuance costs related to revolving credit facilities, the FASB allows the presentation of debt issuance costs as an asset. We adopted the ASU as of January 1, 2016 with retrospective application to our December 31, 2015 Consolidated Balance Sheets. The effect of the adoption was to reclassify debt issuance costs from deferred financing and leasing costs, net of accumulated amortization, as follows: $7.8 million to a contra account as a deduction from the related mortgages and notes payable; and $2.1 million to prepaid expenses and other assets. There was no effect on our Consolidated Statements of Income or Consolidated Statements of Cash Flows.

The FASB recently issued an ASU that requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The ASU is required to be adopted in 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. Our initial analysis of our non-lease related revenue contracts indicates that the adoption of this ASU will not have a material effect on our Consolidated Financial Statements; however, we are still in the process of evaluating this ASU.

The FASB recently issued an ASU that adds to and clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The ASU is required to be adopted in 2018 with retrospective application required. We do not expect such adoption to have a material effect on our Consolidated Statements of Cash Flows.
 
The FASB recently issued an ASU which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The ASU requires lessors to account for leases using an approach that is substantially equivalent to the existing guidance and is effective for reporting periods beginning in 2019 with early adoption permitted. We are in the process of evaluating this ASU.

The FASB recently issued an ASU that requires, among other things, the use of a new current expected credit loss ("CECL") model in determining our allowances for doubtful accounts with respect to accounts receivable, accrued straight-line rents receivable and mortgages and notes receivable. The CECL model requires that we estimate our lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. We will also be required to disclose information about how we developed the allowances, including changes in the factors (e.g., portfolio mix, credit trends, unemployment, gross domestic product, etc.) that influenced our estimate of expected credit losses and the reasons for those changes. We will apply the ASU’s provisions as a cumulative-effect adjustment to retained earnings upon adoption in 2020. We are in the process of evaluating this ASU.

The FASB recently issued an ASU that requires management of all entities to evaluate whether there are conditions and events that raise substantial doubt about the entity's ability to continue as a going concern within one year after the financial statements are issued. We adopted the ASU as of December 31, 2016. We added additional disclosures in Note 6 as a result of the adoption of this ASU.

[1] Our secured mortgage loans were collateralized by real estate assets with an aggregate undepreciated book value of $251.9 million at December 31, 2016. Our fixed rate mortgage loans generally are either locked out to prepayment for all or a portion of their term or are prepayable subject to certain conditions including prepayment penalties.
[2] This debt was repaid in 2016.
[3] Net of unamortized fair market value premium of $0.8 million and $1.7 million as of December 31, 2016 and 2015, respectively.
[4] Net of unamortized fair market value premium of $0.1 million and $0.2 million as of December 31, 2016 and 2015, respectively.

[8] The interest rate was 1.82% at December 31, 2016.
[9] As more fully described in Note 7, we entered into floating-to-fixed interest rate swaps that effectively fix LIBOR for the original $225.0 million portion of this loan. Accordingly, the equivalent fixed rate of this amount is 2.78%. The interest rate on the remaining $125.0 million was 1.77% at December 31, 2016.
[10] The interest rate was 1.72% at December 31, 2016.
[11] There were no amounts outstanding on the revolving credit facility at December 31, 2016.
