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 March 31, 2016, we owned or had an interest in 31.2 million rentable square feet of in-service properties, 1.3 million rentable square feet of properties under development and approximately 500 acres of development land.
 
The Company is the sole general partner of the Operating Partnership. At March 31, 2016, the Company owned all of the Preferred Units and 97.0 million, or 97.1%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.9 million Common Units.

Common Stock Offerings
 
During the three months ended March 31, 2016, the Company issued 1,054,496 shares of Common Stock under its equity distribution agreements at an average gross sales price of $45.86 per share and received net proceeds, after sales commissions, of $47.6 million.

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 three months ended March 31, 2015 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. In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. At March 31, 2016, we had involvement with, but are not the primary beneficiary in, an entity that we concluded to be a variable interest entity. 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 2015 Annual Report on Form 10-K.

During 2015, as a result of our partner’s irrevocable exercise of a buy-sell provision in our SF-HIW Harborview Plaza, LP 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. Such retrospective revision is denoted using "as revised" on our Consolidated Statements of Equity and Capital as of March 31, 2015.

1.    Description of Business and Significant Accounting Policies – Continued

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") recently issued an accounting standards update that requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The accounting standards update is required to be adopted in 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. We are in the process of evaluating this accounting standards update.
 
The FASB recently issued an accounting standards update that 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 accounting standards update as of January 1, 2016 and there was no impact to consolidated entities included in our Consolidated Financial Statements. However, in reevaluating our previous consolidation conclusions upon adoption of the accounting standards update, we determined our 12.5% equity interest in an unconsolidated affiliate to be an interest in a variable interest entity because certain of its limited partners do not have substantive kick-out or participating rights. We do not qualify as the primary beneficiary since our obligation to absorb losses and receive benefits of the variable interest entity is less than that of the other general partner. Accordingly, the entity is not consolidated. Our maximum exposure to loss with respect to this arrangement is limited to the $1.6 million carrying value of our 12.5% investment in the unconsolidated affiliate.
 
The FASB recently issued an accounting standards update 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 accounting standards update 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.

The FASB recently issued an accounting standards update which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors.  The accounting standards update requires lessors to account for leases using an approach that is substantially equivalent to the existing guidance and is effective for reporting periods beginning after December 15, 2018 with early adoption permitted.  We are in the process of evaluating this accounting standards update.

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; and

a building for a sale price of $6.4 million (before closing credits to buyer of $0.5 million) and recorded a gain on disposition of property of $2.0 million.

Mortgages and notes receivable were $9.7 million and $2.1 million at March 31, 2016 and December 31, 2015, 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 March 31, 2016, our mortgages and notes receivable were not in default and there were no other indicators of impairment.

During the first quarter of 2016, Concourse Center Associates, LLC 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 secured debt.

During the first quarter of 2016, 4600 Madison Associates, LP sold land to an unrelated third party for a sale price of $3.4 million and recorded a gain on disposition of property of $1.0 million. We recorded $0.1 million as our share of this gain through equity in earnings of unconsolidated affiliates. Simultaneously with the sale, the joint venture used all of the proceeds to pay down $3.4 million on its secured mortgage loan with an effective interest rate of 6.85%.

At March 31, 2016, our secured mortgage loans were collateralized by real estate assets with an aggregate undepreciated book value of $315.8 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 $258.0 million and $257.0 million outstanding under our revolving credit facility at March 31, 2016 and April 19, 2016, respectively. At both March 31, 2016 and April 19, 2016, we had $0.2 million of outstanding letters of credit, which reduces the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility at March 31, 2016 and April 19, 2016 was $216.8 million and $217.8 million, respectively.

During the first quarter of 2016, we prepaid without penalty the $350.0 million balance on our unsecured bridge facility that was originally scheduled to mature in March 2016.

We are currently in compliance with financial covenants and other requirements with respect to our consolidated debt.

Derivative Financial Instruments
 
During the first quarter of 2016, we obtained $150.0 million notional amount of forward-starting swaps that effectively lock the underlying treasury rate at 1.90% with respect to a forecasted debt issuance expected to occur between June 15, 2016 and March 15, 2017. The counterparties under the 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 three months ended March 31, 2016 and 2015. We have no collateral requirements related to our interest rate swaps.

Amounts reported in accumulated other comprehensive loss ("AOCL") related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the period from April 1, 2016 through March 31, 2017, we estimate that $3.3 million will be reclassified to interest expense.

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

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

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

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

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

Our Level 2 asset is the fair value of our mortgages and notes receivable. Our Level 2 liabilities include the fair value of our mortgages and notes payable and interest rate swaps.

The fair value of mortgages and notes receivable and mortgages and notes payable is estimated by the income approach utilizing contractual cash flows and market-based interest rates to approximate the price that would be paid in an orderly transaction between market participants. The fair value of interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments of interest rate swaps are based on the expectation of future 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 included 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 was 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.

Share-Based Payments
 
During the three months ended March 31, 2016, the Company granted 244,664 stock options with an exercise price equal to the closing market price of a share of Common Stock on 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 $4.61. During the three months ended March 31, 2016, the Company also granted 66,486 shares of time-based restricted stock and 56,346 shares of total return-based restricted stock with weighted average grant date fair values per share of $43.19 and $41.25, respectively. We recorded share-based compensation expense of $3.6 million and $3.9 million during the three months ended March 31, 2016 and 2015, respectively. At March 31, 2016, there was $7.8 million of total unrecognized share-based compensation costs, which will be recognized over a weighted average remaining contractual term of 2.7 years.

Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Accounting, Policy [Policy Text Block]
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 three months ended March 31, 2015 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. In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. At March 31, 2016, we had involvement with, but are not the primary beneficiary in, an entity that we concluded to be a variable interest entity. 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 2015 Annual Report on Form 10-K.

During 2015, as a result of our partner’s irrevocable exercise of a buy-sell provision in our SF-HIW Harborview Plaza, LP 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. Such retrospective revision is denoted using "as revised" on our Consolidated Statements of Equity and Capital as of March 31, 2015.
Use of Estimates, Policy [Policy Text Block]
Use of Estimates

The preparation of consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. Actual results could differ from those estimates.
Recently Issued Accounting Standards, Policy [Policy Text Block]
Recently Issued Accounting Standards

The Financial Accounting Standards Board ("FASB") recently issued an accounting standards update that requires the use of a new five-step model to recognize revenue from customer contracts. The five-step model requires that we identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when we satisfy the performance obligations. We will also be required to disclose information regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The accounting standards update is required to be adopted in 2018. Retrospective application is required either to all periods presented or with the cumulative effect of initial adoption recognized in the period of adoption. We are in the process of evaluating this accounting standards update.
 
The FASB recently issued an accounting standards update that 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 accounting standards update as of January 1, 2016 and there was no impact to consolidated entities included in our Consolidated Financial Statements. However, in reevaluating our previous consolidation conclusions upon adoption of the accounting standards update, we determined our 12.5% equity interest in an unconsolidated affiliate to be an interest in a variable interest entity because certain of its limited partners do not have substantive kick-out or participating rights. We do not qualify as the primary beneficiary since our obligation to absorb losses and receive benefits of the variable interest entity is less than that of the other general partner. Accordingly, the entity is not consolidated. Our maximum exposure to loss with respect to this arrangement is limited to the $1.6 million carrying value of our 12.5% investment in the unconsolidated affiliate.
 
The FASB recently issued an accounting standards update 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 accounting standards update 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.

The FASB recently issued an accounting standards update which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors.  The accounting standards update requires lessors to account for leases using an approach that is substantially equivalent to the existing guidance and is effective for reporting periods beginning after December 15, 2018 with early adoption permitted.  We are in the process of evaluating this accounting standards update.
