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 June 30, 2017, we owned or had an interest in 32.0 million rentable square feet of in-service properties, 1.2 million rentable square feet of properties under development and approximately 400 acres of development land.
 
The Company is the sole general partner of the Operating Partnership. At June 30, 2017, the Company owned all of the Preferred Units and 102.8 million, or 97.3%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.8 million Common Units. During the six months ended June 30, 2017, the Company redeemed 6,000 Common Units for a like number of shares of Common Stock.

Common Stock Offerings
 
During the first quarter of 2017, we entered into separate equity distribution agreements in which the Company may offer and sell up to $300.0 million in aggregate gross sales price of shares of Common Stock. During the three and six months ended June 30, 2017, the Company issued 1,177,734 and 1,363,919 shares, respectively, of Common Stock under its equity distribution agreements at an average gross sales price of $51.03 and $50.85 per share, respectively, and received net proceeds, after sales commissions, of $59.2 million and $68.3 million, respectively.

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

The Company's Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership's Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. All intercompany transactions and accounts have been eliminated.

The unaudited interim consolidated financial statements and accompanying unaudited consolidated financial information, in the opinion of management, contain all adjustments (including normal recurring accruals) necessary for a fair presentation of our financial position, results of operations and cash flows. We have condensed or omitted certain notes and other information from the interim Consolidated Financial Statements presented in this Quarterly Report as permitted by SEC rules and regulations. These Consolidated Financial Statements should be read in conjunction with our 2016 Annual Report on Form 10-K.

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.

Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("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. Upon adoption of the ASU in 2018, we expect to utilize the modified retrospective approach. Our initial analysis of our non-lease related revenue contracts indicates that the adoption of this ASU will impact the financial statement disclosure of these contracts with no material impact on the timing of revenue recognition; however, we are still in the process of evaluating this ASU. We expect additional impact of this ASU upon adoption of the ASU related to accounting for leases discussed below for certain lease revenue streams that will be required to be evaluated as non-lease components using the five-step revenue recognition model.
 
The FASB 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 issued an ASU that clarifies and narrows the definition of a business used in determining whether to account for a transaction as an asset acquisition or business combination. The guidance requires evaluation of the fair value of the assets acquired to determine if it is concentrated in a single identifiable asset or a group of similar identifiable assets. If so, the transferred assets would not be a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs. The ASU is required to be adopted in 2018 and applied prospectively. Upon adoption of this ASU, we expect that the majority of our future acquisitions would not meet the definition of a business; therefore, the related acquisition costs would be capitalized as part of the purchase price.

The FASB issued an ASU that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance requires modification accounting if the value, vesting conditions or classification of the award changes. The ASU is required to be adopted in 2018 and applied prospectively. We do not expect such adoption to have a material effect on our Consolidated Financial Statements.

The FASB 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. Our initial analysis of our leases indicates that upon adoption of the ASU, certain lease revenue streams that are currently accounted for using the lease accounting standard will be accounted for as non-lease components using the five-step revenue recognition model discussed above. We are in the process of evaluating this ASU.

The FASB 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.

Mortgages and notes receivable were $6.8 million and $8.8 million at June 30, 2017 and December 31, 2016, respectively. 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 June 30, 2017, our mortgages and notes receivable were not in default and there were no other indicators of impairment.

At June 30, 2017, our secured mortgage loans were collateralized by real estate assets with an aggregate undepreciated book value of $147.8 million.

Our $475.0 million unsecured revolving credit facility is scheduled to mature in January 2018 and includes an accordion feature that allows for an additional $75.0 million of borrowing capacity subject to additional lender commitments. Assuming no defaults have occurred, we have an option to extend the maturity for two additional six-month periods. The interest rate at our current credit ratings is LIBOR plus 110 basis points and the annual facility fee is 20 basis points. There was $111.0 million and $97.0 million outstanding under our revolving credit facility at June 30, 2017 and July 18, 2017, respectively. At both June 30, 2017 and July 18, 2017, we had $0.6 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 June 30, 2017 and July 18, 2017 was $363.4 million and $377.4 million, respectively.
 
During the second quarter of 2017, we prepaid without penalty a secured mortgage loan with a fair market value of $108.2 million with an effective interest rate of 4.22% that was originally scheduled to mature in November 2017. We recorded $0.4 million of gain on debt extinguishment related to this prepayment.
 
5.    Mortgages and Notes Payable - Continued
 
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 were scheduled to mature in July 2017. The first mortgage and subordinated notes had effective interest rates of 5.36% and 8.6%, respectively. The subordinated note and accrued interest thereon can be satisfied, in certain circumstances, upon payment of a "waterfall payment" equal to a cash payment of 50.0% of the amount by which the net sale proceeds or appraised value at the time of refinancing exceeded (1) the outstanding principal of the first mortgage note, (2) 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 subordinated note was recorded at a projected waterfall payment of $1.0 million. During the second quarter of 2017, both notes were retired upon payment of the $18.0 million principal balance on the first mortgage note and a $0.5 million waterfall payment relating to the subordinated note, which resulted in $0.4 million of gain on debt extinguishment.
 
During the second quarter of 2017, we obtained a $100.0 million secured mortgage loan from a third party lender with an effective interest rate of 4.0%. This loan is scheduled to mature in May 2029. We incurred $0.8 million of debt issuance costs in connection with this loan, which will be amortized over the term of the loan.
 
During the first quarter of 2017, the Operating Partnership issued $300.0 million aggregate principal amount of 3.875% notes due 2027, less original issue discount of $4.0 million. These notes were priced to yield 4.038%. Underwriting fees and other expenses were incurred that aggregated $2.5 million; these costs were deferred and will be amortized over the term of the notes.
 
During the first quarter of 2017, we paid off at maturity $379.7 million principal amount of 5.85% unsecured notes.
 
During the first quarter of 2017, we amended our $150.0 million unsecured bank term loan that is scheduled to mature in January 2022 by increasing the borrowed amount to $200.0 million. The interest rate on this term loan at our current credit ratings is LIBOR plus 110 basis points. The underlying LIBOR rate with respect to $50.0 million of the unsecured bank term loan has been effectively fixed for the term through floating-to-fixed interest rate swaps as discussed in Note 6. We incurred $0.3 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.
 
We are currently in compliance with financial covenants and other requirements with respect to our consolidated debt.
 
We have considered our short-term liquidity needs within one year from July 25, 2017 (the date of issuance of the quarterly financial statements) 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 during such one-year period, including the $200.0 million principal amount of unsecured notes due April 15, 2018. We have concluded it is probable we will meet these short-term liquidity requirements through a combination of the following:
 
available cash and cash equivalents;
 
cash flows from operating activities;
 
issuance of debt securities by the Operating Partnership (some of which debt securities may be hedged to a fixed interest rate pursuant to the forward-starting swaps referred to in Note 6);
 
issuance of secured debt;
 
bank term loans;
 
borrowings under our revolving credit facility;
 
issuance of equity securities by the Company or the Operating Partnership; and
 
the disposition of non-core assets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

During the second quarter of 2017, we entered into $150.0 million notional amount of forward-starting swaps that effectively lock the underlying 10-year treasury rate at 2.44% with respect to a planned issuance of debt securities by the Operating Partnership expected to occur prior to May 15, 2018.

During the second quarter of 2017, we entered into floating-to-fixed interest rate swaps through January 2022 with respect to an aggregate of $50.0 million LIBOR-based borrowings. These swaps effectively fix the underlying one-month LIBOR rate at a weighted average rate of 1.693%.

During 2016, we entered into $150.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at 1.90% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $300.0 million aggregate principal amount of 3.875% notes due 2027 during the first quarter of 2017, we terminated the forward-starting swaps resulting in an unrealized gain of $7.3 million in accumulated other comprehensive income.

The counterparties under these swaps are major financial institutions. The swap agreements contain a provision whereby if we default on certain of our 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.

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 six months ended June 30, 2017 and 2016. 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 the period from July 1, 2017 through June 30, 2018, we estimate that $0.4 million will be reclassified as a net increase to interest expense.

Jun. 30, 2017
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 interest rate swaps. Our Level 2 liabilities include the fair value of our mortgages and notes payable and remaining 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 tax increment financing bond was assigned in conjunction with a sale during the first quarter of 2016. The estimated fair value at the date of sale of $11.2 million was equal to the outstanding principal amount due on the bond.

During the six months ended June 30, 2017, the Company granted 168,748 stock options with an exercise price equal to the last reported stock price of our Common Stock on the New York Stock Exchange on the last trading day prior to the date of grant. The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model, which resulted in a weighted average grant date fair value per share of $6.72. During the six months ended June 30, 2017, the Company also granted 61,404 shares of time-based restricted stock and 49,344 shares of total return-based restricted stock with weighted average grant date fair values per share of $52.49 and $49.59, respectively. We recorded share-based compensation expense of $1.1 million and $1.0 million during the three months ended June 30, 2017 and 2016, respectively, and $4.8 million and $4.6 million during the six months ended June 30, 2017 and 2016, respectively. At June 30, 2017, there was $7.0 million of total unrecognized share-based compensation costs, which will be recognized over a weighted average remaining contractual term of 2.5 years.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Presentation, Policy
Basis of Presentation
 
Our Consolidated Financial Statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).

The Company's Consolidated Financial Statements include the Operating Partnership, wholly owned subsidiaries and those entities in which the Company has the controlling interest. The Operating Partnership's Consolidated Financial Statements include wholly owned subsidiaries and those entities in which the Operating Partnership has the controlling interest. All intercompany transactions and accounts have been eliminated.

The unaudited interim consolidated financial statements and accompanying unaudited consolidated financial information, in the opinion of management, contain all adjustments (including normal recurring accruals) necessary for a fair presentation of our financial position, results of operations and cash flows. We have condensed or omitted certain notes and other information from the interim Consolidated Financial Statements presented in this Quarterly Report as permitted by SEC rules and regulations. These Consolidated Financial Statements should be read in conjunction with our 2016 Annual Report on Form 10-K.

Use of Estimates, Policy
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.
Recently Issued Accounting Standards, Policy
Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") issued an accounting standards update ("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. Upon adoption of the ASU in 2018, we expect to utilize the modified retrospective approach. Our initial analysis of our non-lease related revenue contracts indicates that the adoption of this ASU will impact the financial statement disclosure of these contracts with no material impact on the timing of revenue recognition; however, we are still in the process of evaluating this ASU. We expect additional impact of this ASU upon adoption of the ASU related to accounting for leases discussed below for certain lease revenue streams that will be required to be evaluated as non-lease components using the five-step revenue recognition model.
 
The FASB 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 issued an ASU that clarifies and narrows the definition of a business used in determining whether to account for a transaction as an asset acquisition or business combination. The guidance requires evaluation of the fair value of the assets acquired to determine if it is concentrated in a single identifiable asset or a group of similar identifiable assets. If so, the transferred assets would not be a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs. The ASU is required to be adopted in 2018 and applied prospectively. Upon adoption of this ASU, we expect that the majority of our future acquisitions would not meet the definition of a business; therefore, the related acquisition costs would be capitalized as part of the purchase price.

The FASB issued an ASU that clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The guidance requires modification accounting if the value, vesting conditions or classification of the award changes. The ASU is required to be adopted in 2018 and applied prospectively. We do not expect such adoption to have a material effect on our Consolidated Financial Statements.

The FASB 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. Our initial analysis of our leases indicates that upon adoption of the ASU, certain lease revenue streams that are currently accounted for using the lease accounting standard will be accounted for as non-lease components using the five-step revenue recognition model discussed above. We are in the process of evaluating this ASU.

The FASB 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.
