Description of Business and Significant Accounting Policies Description of Business and Significant Accounting Policies

Description of Business
 
Highwoods Properties, Inc. (the “Company”) is a fully integrated real estate investment trust (“REIT”) that provides leasing, management, development, construction and other customer-related services for its properties and for third parties. The Company conducts its activities through Highwoods Realty Limited Partnership (the “Operating Partnership”). At June 30, 2019, we owned or had an interest in 31.1 million rentable square feet of in-service properties, 1.2 million rentable square feet of office properties under development and approximately 325 acres of development land.
 
The Company is the sole general partner of the Operating Partnership. At June 30, 2019, the Company owned all of the Preferred Units and 103.3 million, or 97.4%, of the Common Units in the Operating Partnership. Limited partners owned the remaining 2.7 million Common Units. During the six months ended June 30, 2019, the Company redeemed 8,000 Common Units for a like number of shares of Common Stock.
 
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. 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. In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. At June 30, 2019, we have involvement with, and are the primary beneficiary in, an entity that we concluded to be a variable interest entity (see Note 3). All intercompany transactions and accounts have been eliminated.
 
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 2018 Annual Report on Form 10-K.
 
Certain amounts within the Consolidated Statements of Income for the three and six months ended June 30, 2018 were removed and/or combined to conform to the current year presentation.

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 $50.1 million and $46.9 million for the three months ended June 30, 2019 and 2018, respectively, and $108.4 million and $94.3 million for the six months ended June 30, 2019 and 2018, respectively.
 
Leases
 
See Note 2 for policies and related disclosures with respect to our leases as both a lessee and lessor.

Insurance
 
We are primarily self-insured for health care claims for participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities. At June 30, 2019, a reserve of $0.6 million was recorded to cover estimated reported and unreported claims.

Other Events
 
During the first quarter of 2019, Laser Spine Institute, which leased a 176,000 square foot building with structured parking in Tampa’s Westshore submarket, suddenly ceased operations. As a result of this sudden closure, we incurred $5.6 million of credit losses on operating lease receivables and $2.3 million of write-offs of lease incentives (in rental and other revenues), $4.1 million of write-offs of notes receivable (in other income/(loss)) and $11.6 million of write-offs of tenant improvements and deferred leasing costs (in depreciation and amortization).

Recently Issued Accounting Standards
 
The Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) that eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item when the hedged item affects earnings. We adopted the ASU as of January 1, 2019 with no material effect on our Consolidated Financial Statements.
 
The FASB issued an ASU that changes certain disclosure requirements for fair value measurements. The ASU is required to be adopted in 2020 and applied prospectively. We do not expect such adoption to have a material effect on our Notes to Consolidated Financial Statements.

Leases
 
On January 1, 2019, we adopted Accounting Standards Codification Topic 842 “Leases” (“ASC 842”), which supersedes Accounting Standards Codification Topic 840 “Leases” (“ASC 840”). Information in this Note 2 with respect to our leases and lease related costs as both lessee and lessor and lease related receivables as lessor is presented under ASC 842 as of June 30, 2019 and for the three and six months ended June 30, 2019 and under ASC 840 as of and for the year ended December 31, 2018.
 
We adopted ASC 842 using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2019 as a result of this adoption. ASC 842 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. We operate as both a lessor and a lessee. As a lessor, we are required under ASC 842 to account for leases using an approach that is substantially equivalent to ASC 840's guidance for operating leases and other leases such as sales-type leases and direct financing leases. In addition, ASC 842 requires lessors to capitalize and amortize only incremental direct leasing costs. As a lessee, we are required under the new standard to apply a dual approach, classifying leases, such as ground leases, as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. ASC 842 also requires lessees to record a right of use asset and a lease liability for all leases with a term of greater than a year regardless of their classification. We have also elected the practical expedient not to recognize right of use assets and lease liabilities for leases with a term of a year or less.
 
On adoption of the standard, we elected the package of practical expedients provided for in ASC 842, including:
 
No reassessment of whether any expired or existing contracts were or contained leases;
 
No reassessment of the lease classification for any expired or existing leases; and
 
No reassessment of initial direct costs for any existing leases.
 
The package of practical expedients was made as a single election and was consistently applied to all existing leases as of January 1, 2019. We also elected the practical expedient provided to lessors in a subsequent amendment to ASC 842 that removed the requirement to separate lease and nonlease components, provided certain conditions were met.
 
Information as Lessor Under ASC 842
 
To generate positive cash flow, as a lessor, we lease our office properties to lessees in exchange for fixed monthly payments that cover rent, property taxes, insurance and certain cost recoveries, primarily common area maintenance (“CAM”). Office properties owned by us that are under lease are located in Atlanta, Greensboro, Memphis, Nashville, Orlando, Pittsburgh, Raleigh, Richmond and Tampa and are leased to a wide variety of lessees across many industries. Our leases were determined to be operating leases and generally range from three to 10 years. Payments from customers for CAM are considered nonlease components that are separated from lease components and are generally accounted for in accordance with the revenue recognition standard. However, we qualified for and elected the practical expedient related to combining the components because the lease component is classified as an operating lease and the timing and pattern of transfer of CAM income, which is not the predominant component, is the same as the lease component. As such, consideration for CAM is accounted for as part of the overall consideration in the lease. Payments from customers for property taxes and insurance are considered noncomponents of the lease and therefore no consideration is allocated to them because they do not transfer a good or service to the customer. Fixed contractual payments from our 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.
 
Some of our leases are subject to annual changes in the Consumer Price Index (“CPI”). Although increases in the CPI are not estimated as part of our measurement of straight-line rental revenue, to the extent that actual CPI is greater or less than the CPI at lease commencement, the amount of straight-line rent recognized in a given year is affected accordingly.
 
Some of our leases have termination options and/or extension options. Termination options allow the customer to terminate the lease prior to the end of the lease term under certain circumstances. Termination options generally become effective half way
or further into the original lease term and require advance notification from the customer and payment of a termination fee that reimburses us for a portion of the remaining rent under the original lease term and the undepreciated lease inception costs such as commissions, tenant improvements and lease incentives. 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. Our extension options generally require a re-negotiation with the customer at market rates.
 
Initial direct costs, primarily commissions, related to the leasing of our office 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 and our in-house personnel for new leases or lease renewals are capitalized. Capitalized leasing costs are amortized on a straight-line basis over the initial fixed terms of the respective leases. All other costs to negotiate or arrange a lease are expensed as incurred.
 
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.
 
Lease related receivables, which include accounts receivable and accrued straight-line rents receivable, are reduced for credit losses. Such amounts are recognized as a reduction to rental and other revenues. We regularly evaluate the collectability of our lease related receivables. Our evaluation of collectability 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 reduce the related receivable balance for amounts deemed uncollectible. If our assumptions regarding the collectability of lease related receivables prove incorrect, we could experience credit losses in excess of what was recognized in rental and other revenues.
 
We recognized rental and other revenues related to operating lease payments of $180.7 million and $350.1 million, respectively, during the three and six months ended June 30, 2019, of which variable lease payments were $16.4 million and $31.9 million, respectively.

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.
 
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 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.
  
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.
 
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.
 
Our real estate assets are leased to customers under operating leases. The minimum rental amounts under the leases are generally subject to scheduled fixed increases. Generally, the leases also provide that we receive cost recovery income from customers for increases in certain costs above the costs incurred during a contractually specified base year.

We have 20 properties subject to operating ground leases in Atlanta, Nashville, Orlando, Raleigh and Tampa with a weighted average remaining term of 52 years. Rental payments on these leases are adjusted periodically based on either the CPI or on a pre-determined schedule. The monthly payments on a pre-determined schedule are recognized on a straight-line basis over the terms of the respective leases. Changes in the CPI are not estimated as part of our measurement of straight-line rental expense. Upon initial adoption of ASC 842, we recognized a lease liability of $35.3 million (in accounts payable, accrued expenses and other liabilities) and a related right of use asset of $29.7 million (in prepaid expenses and other assets) on our Consolidated Balance Sheets equal to the present value of the minimum lease payments required under each ground lease. The difference between the recorded lease liability and right of use asset represents the accrued straight-line rent liability previously recognized under ASC 840. We used a discount rate of approximately 4.5%, which was derived from our assessment of the credit quality of the Company and adjusted to reflect secured borrowing, estimated yield curves and long-term spread adjustments over appropriate tenors. Some of our ground leases contain extension options; however, these did not impact our calculation of the right of use asset and liability as they extend beyond the useful life of the properties subject to the operating ground leases. We recognized $0.6 million and $1.2 million of ground lease expense during the three and six months ended June 30, 2019, respectively. Cash payments related to these leases were $0.7 million and $1.2 million during the three and six months ended June 30, 2019, respectively.

During the second quarter of 2019, we and The Bromley Companies formed a joint venture (the "Midtown One joint venture”) to construct Midtown One, a 150,000 square foot, multi-customer office building located in the mixed-use Midtown Tampa project in Tampa’s Westshore submarket. Midtown One has an anticipated total investment of $71.3 million. Construction of Midtown One is projected to begin in the fourth quarter of 2019 with a scheduled completion date in the second quarter of 2021. At closing, we agreed to contribute cash of $20.0 million ($12.8 million of which was funded and/or placed in escrow as of June 30, 2019) in exchange for an 80.0% interest in the Midtown One joint venture and The Bromley Companies contributed land valued at $5.0 million in exchange for the remaining 20.0% interest. We also committed to provide a $46.3 million interest-only secured construction loan to the Midtown One joint venture that is scheduled to mature on the second anniversary of completion. The loan bears interest at LIBOR plus 250 basis points. As of June 30, 2019, no amounts under the loan have been funded.

We determined that we have a variable interest in the Midtown One joint venture primarily because the entity was designed to pass along interest rate risk, equity price risk and operation risk to us as both a debt and an equity holder and The Bromley Companies as an equity holder. The Midtown One joint venture was further determined to be a variable interest entity as it requires additional subordinated financial support in the form of a loan because the initial equity investment provided by us and The Bromley Companies is not sufficient to finance its planned investments and operations. We, as majority owner and managing member and through our control rights as set forth in the joint venture's governance documents, were determined to be the primary beneficiary as we have both the power to direct the activities that most significantly affect the entity (primarily lease rates, property operations and capital expenditures) and significant economic exposure through our equity investment and loan commitment. As such, the Midtown One joint venture was consolidated as of June 30, 2019 and for the period May 29, 2019 through June 30, 2019 and all intercompany transactions and accounts were eliminated. The following table sets forth the assets and liabilities of the Midtown One joint venture included on our Consolidated Balance Sheets:

At June 30, 2019, our secured mortgage loan was collateralized by real estate assets with an undepreciated book value of $146.2 million.
 
Our $600.0 million unsecured revolving credit facility is scheduled to mature in January 2022 and includes an accordion feature that allows for an additional $400.0 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 100 basis points and the annual facility fee is 20 basis points. There was $136.0 million and $121.0 million outstanding under our revolving credit facility at June 30, 2019 and July 16, 2019, respectively. At both June 30, 2019 and July 16, 2019, we had $0.1 million of outstanding letters of credit, which reduces the availability on our revolving credit facility. As a result, the unused capacity of our revolving credit facility at June 30, 2019 and July 16, 2019 was $463.9 million and $478.9 million, respectively.
 
During the first quarter of 2019, we prepaid without penalty our $225.0 million, seven-year unsecured bank term loan, which was scheduled to mature in June 2020. The interest rate on the term loan was LIBOR plus 110 basis points. We recorded $0.4 million of loss on debt extinguishment related to this prepayment.

During the first quarter of 2019, the Operating Partnership issued $350.0 million aggregate principal amount of 4.20% notes due April 2029, less original issuance discount of $1.0 million. These notes were priced to yield 4.234%. Underwriting fees and other expenses were incurred that aggregated $3.1 million; these costs were deferred and will be amortized over the term of the notes.
 
We are currently in compliance with financial covenants with respect to our consolidated debt.
 
We have considered our short-term liquidity needs and the adequacy of our estimated cash flows from operating activities and other available financing sources to meet these needs. We intend to 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;
 
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.

During 2018, we entered into an aggregate of $225.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at a weighted average of 2.86% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $350.0 million aggregate principal amount of 4.20% notes due April 2029 during the first quarter of 2019, we terminated the forward-starting swaps and paid cash upon settlement. The unrealized loss of $5.1 million in accumulated other comprehensive income will be reclassified to interest expense as interest payments are made on the debt.

The counterparties under our 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. We have no collateral requirements related to our interest rate swaps.
 
Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our debt. During the period from July 1, 2019 through June 30, 2020, we estimate that $1.0 million will be reclassified as a net decrease 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 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 assets include any real estate assets recorded at fair value on a non-recurring basis as a result of our quarterly impairment analysis, which are valued using the terms of definitive sales contracts or the sales comparison approach.

The following table sets forth our assets and liabilities and the Company's noncontrolling interests in the Operating Partnership that are measured or disclosed at fair value within the fair value hierarchy.

__________
(1)    Amounts recorded at historical cost on our Consolidated Balance Sheets at June 30, 2019 and December 31, 2018.

The impaired real estate assets that were measured in the second quarter of 2019 and the fourth quarter of 2018 at fair values of $0.7 million and $10.3 million, respectively, and deemed to be Level 3 assets were valued based primarily on market-based inputs and our assumptions about the use of the assets, as observable inputs were not available. In the absence of observable inputs, we estimate the fair value of real estate using unobservable local and national industry market data such as comparable sales, sales contracts and appraisals to assist us in our estimation of fair value. Significant increases or decreases in any valuation inputs in isolation would result in a significantly lower or higher fair value measurement.

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”).

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. In addition, we consolidate those entities deemed to be variable interest entities in which we are determined to be the primary beneficiary. At June 30, 2019, we have involvement with, and are the primary beneficiary in, an entity that we concluded to be a variable interest entity (see Note 3). All intercompany transactions and accounts have been eliminated.
 
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 2018 Annual Report on Form 10-K.
 
Certain amounts within the Consolidated Statements of Income for the three and six months ended June 30, 2018 were removed and/or combined to conform to the current year presentation.

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
Insurance
Insurance
 
We are primarily self-insured for health care claims for participating employees. We have stop-loss coverage to limit our exposure to significant claims on a per claim and annual aggregate basis. We determine our liabilities for claims, including incurred but not reported losses, based on all relevant information, including actuarial estimates of claim liabilities.
Recently Issued Accounting Standards
Recently Issued Accounting Standards
 
The Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) that eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item when the hedged item affects earnings. We adopted the ASU as of January 1, 2019 with no material effect on our Consolidated Financial Statements.
 
The FASB issued an ASU that changes certain disclosure requirements for fair value measurements. The ASU is required to be adopted in 2020 and applied prospectively. We do not expect such adoption to have a material effect on our Notes to Consolidated Financial Statements.
On January 1, 2019, we adopted Accounting Standards Codification Topic 842 “Leases” (“ASC 842”), which supersedes Accounting Standards Codification Topic 840 “Leases” (“ASC 840”). Information in this Note 2 with respect to our leases and lease related costs as both lessee and lessor and lease related receivables as lessor is presented under ASC 842 as of June 30, 2019 and for the three and six months ended June 30, 2019 and under ASC 840 as of and for the year ended December 31, 2018.
 
We adopted ASC 842 using the modified retrospective approach whereby the cumulative effect of adoption was recognized on the adoption date and prior periods were not restated. There was no net cumulative effect adjustment to retained earnings as of January 1, 2019 as a result of this adoption. ASC 842 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. We operate as both a lessor and a lessee. As a lessor, we are required under ASC 842 to account for leases using an approach that is substantially equivalent to ASC 840's guidance for operating leases and other leases such as sales-type leases and direct financing leases. In addition, ASC 842 requires lessors to capitalize and amortize only incremental direct leasing costs. As a lessee, we are required under the new standard to apply a dual approach, classifying leases, such as ground leases, as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. ASC 842 also requires lessees to record a right of use asset and a lease liability for all leases with a term of greater than a year regardless of their classification. We have also elected the practical expedient not to recognize right of use assets and lease liabilities for leases with a term of a year or less.
 
On adoption of the standard, we elected the package of practical expedients provided for in ASC 842, including:
 
No reassessment of whether any expired or existing contracts were or contained leases;
 
No reassessment of the lease classification for any expired or existing leases; and
 
No reassessment of initial direct costs for any existing leases.
 
The package of practical expedients was made as a single election and was consistently applied to all existing leases as of January 1, 2019. We also elected the practical expedient provided to lessors in a subsequent amendment to ASC 842 that removed the requirement to separate lease and nonlease components, provided certain conditions were met.

No reassessment of the lease classification for any expired or existing leases; and
 
No reassessment of initial direct costs for any existing leases.
 
The package of practical expedients was made as a single election and was consistently applied to all existing leases as of January 1, 2019. We also elected the practical expedient provided to lessors in a subsequent amendment to ASC 842 that removed the requirement to separate lease and nonlease components, provided certain conditions were met.
