ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2018

Cash, Cash Equivalents, and Short-Term Investments

Cash, Cash Equivalents, and Short‑Term Investments: Short‑term investments that have a maturity of ninety days or less when purchased are considered cash equivalents. Variable rate demand notes are classified as cash equivalents, as the investments may be redeemed on a daily basis with the original issuer. Short‑term investments consist of FDIC‑insured certificates of deposit and U.S. Treasury securities with original maturities greater than ninety days and remaining maturities less than one year. Interest and dividends related to cash, cash equivalents, and short‑term investments are included in interest and dividend income.

Certificates of deposit are valued at cost plus accrued interest, which approximates fair value. Held-to-maturity U.S. Treasury securities are recorded at amortized cost with interest and amortization of premiums and discounts included in interest income. Quarterly, the Company evaluates held-to-maturity securities for any other-than-temporary impairments related to any intention to sell or requirement to sell before its amortized costs are recovered. If a security is considered to be other-than-temporarily impaired, the difference between amortized cost and the amount that is determined to be recoverable is recorded in earnings.

Restricted Cash

Restricted Cash: Restricted cash consisted of cash deposits at December 31, 2016. Cash that was pledged as collateral, primarily for the Company’s outstanding letters of credit, was classified as restricted. The Company’s letters of credit were primarily issued in support of certain workers’ compensation and third‑party casualty claims liabilities in various states in which the Company is self‑insured. The restricted cash was classified consistent with the classification of the liabilities to which it related and in accordance with the duration of the letters of credit.

Concentration of Credit Risk

Concentration of Credit Risk: The Company is potentially subject to concentrations of credit risk related to the portion of its cash, cash equivalents, and short‑term investments which is not federally insured, as further discussed in Note C.

The Company’s services are provided primarily to customers throughout the United States and, to a lesser extent, Canada, Mexico, and other international locations. On a consolidated basis, the Company had no single customer representing more than 5% of its revenues in 2018, 2017, or 2016 or more than 6% of its accounts receivable balance at December 31, 2018 and 2017. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. Historically, credit losses have been within management’s expectations.

Allowances

Allowances: The Company maintains allowances for doubtful accounts and revenue adjustments. The Company’s allowance for doubtful accounts represents an estimate of potential accounts receivable write‑offs associated with recognized revenue based on historical trends and factors surrounding the credit risk of specific customers. Accounts receivable are written off against the allowance for doubtful accounts and revenue adjustments when accounts are turned over to a collection agency or when the accounts are determined to be uncollectible. The Company’s allowance for revenue adjustments represents an estimate of potential adjustments associated with recognized revenue based upon historical trends and current information regarding trends and business changes.

Property, Plant and Equipment, Including Repairs and Maintenance

Property, Plant and Equipment, Including Repairs and Maintenance: Purchases of property, plant and equipment are recorded at cost. For financial reporting purposes, property, plant and equipment is depreciated principally by the straight‑line method, using the following useful lives: structures – primarily 15 to 60 years; revenue equipment – 3 to 14 years; and other equipment – 2 to 15 years. The Company utilizes tractors and trailers in its operations. Tractors and trailers are commonly referred to as “revenue equipment” in the transportation business. The Company periodically reviews and adjusts, as appropriate, the residual values and useful lives of revenue equipment and other equipment. For tax reporting purposes, accelerated depreciation or cost recovery methods are used. Gains and losses on asset sales are reflected in the year of disposal. Exchanges of nonmonetary assets that have commercial substance are measured based on the fair value of the assets exchanged. Tires purchased with revenue equipment are capitalized as a part of the cost of such equipment, with replacement tires being expensed when placed in service. Repair and maintenance costs associated with property, plant and equipment are expensed as incurred if the costs do not extend the useful life of the asset. If such costs do extend the useful life of the asset, the costs are capitalized and depreciated over the appropriate remaining useful life.

Computer Software Developed or Obtained for Internal Use, Including Web Site Development Costs

Computer Software Developed or Obtained for Internal Use, Including Web Site Development Costs: The Company capitalizes the costs of software acquired from third parties and qualifying internal computer software costs incurred during the application development stage. Costs incurred in the preliminary project stage and postimplementation-operation stage, which includes maintenance and training costs, are expensed as incurred. For financial reporting purposes, capitalized software costs are amortized by the straight‑line method generally over 2 to 7 years. The amount of costs capitalized within any period is dependent on the nature of software development activities and projects in each period.

Impairment Assessment of Long-Lived Assets

Impairment Assessment of Long‑Lived Assets: The Company reviews its long‑lived assets, including property, plant and equipment and capitalized software, which are held and used in its operations, for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If such an event or change in circumstances is present, the Company will estimate the undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. If the sum of the undiscounted future cash flows is less than the carrying amount of the related asset, the Company will recognize an impairment loss. The Company records impairment losses in operating income.

Assets to be disposed of are reclassified as assets held for sale at the lower of their carrying amount or fair value less cost to sell. Assets held for sale primarily represent Asset-Based segment nonoperating properties, older revenue equipment, and other equipment. Adjustments to write down assets to fair value less the amount of costs to sell are reported in operating income. Assets held for sale are expected to be disposed of by selling the assets within the next 12 months. Gains and losses on property and equipment are reported in operating income. Assets held for sale of $0.7 million and $1.4 million are reported within other noncurrent assets as of December 31, 2018 and 2017, respectively. At December 31, 2018 and 2017, management was not aware of any events or circumstances indicating the Company’s long‑lived assets would not be recoverable.

Goodwill and Intangible Assets

Goodwill and Intangible Assets: Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. Goodwill is not amortized, but rather is evaluated for impairment annually or more frequently if indicators of impairment exist. The Company’s measurement of goodwill impairment involves a comparison of the estimated fair value of a reporting unit to its carrying value. Fair value is derived using a combination of valuation methods, including earnings before interest, taxes, depreciation, and amortization (EBITDA) and revenue multiples (market approach) and the present value of discounted cash flows (income approach). For annual and interim impairment tests, the Company is required to record an impairment charge, if any, by the amount a reporting unit’s fair value is exceeded by the carrying value of the reporting unit, limited to the carrying value of goodwill included in the reporting unit. The Company’s annual impairment testing is performed as of October 1.

Indefinite‑lived intangible assets are also not amortized but rather are evaluated for impairment annually or more frequently if indicators of impairment exist. If the carrying amount of the intangible asset exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess. Fair values are determined based on a discounted cash flow model, similar to the goodwill analysis.

The Company amortizes finite‑lived intangible assets over their respective estimated useful lives. Finite‑lived intangible assets are also evaluated for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. In reviewing finite‑lived intangible assets for impairment, the carrying amount of the asset is compared to the estimated undiscounted future cash flows expected from the use of the asset and its eventual disposition. If such cash flows are not sufficient to support the recorded value, an impairment loss to reduce the carrying value of the asset to its estimated fair value shall be recognized in operating income.

Income Taxes

Income Taxes: The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities, which are recorded as noncurrent by jurisdiction, are recognized based on the temporary differences between the book value and the tax basis of certain assets and liabilities and the tax effect of operating loss and tax credit carryforwards. Deferred income taxes relate principally to asset and liability basis differences resulting from the timing of depreciation deductions and to temporary differences in the recognition of certain revenues and expenses. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date. The Company classifies any interest and penalty amounts related to income tax matters as operating expenses.

Management applies considerable judgment in determining the consolidated income tax provision, including valuation allowances on deferred tax assets. The valuation allowance for deferred tax assets is determined by evaluating whether it is more likely than not that the benefits of deferred tax assets will be realized through future reversal of existing taxable temporary differences, taxable income in carryback years in jurisdictions in which they are allowable, projected future taxable income, or tax‑planning strategies. Uncertain tax positions, which also require significant judgment, are measured to determine the amounts to be recognized in the financial statements. The income tax provision and valuation allowances are complicated by complex and frequently changing rules administered in multiple jurisdictions, including U.S. federal, state, and foreign governments.

The Company’s income taxes for the years ended December 31, 2018 and 2017 were impacted by the recognition of the effects of the Tax Cuts and Jobs Act (the “Tax Reform Act”) that was signed into law on December 22, 2017 (see Note E).

Book Overdrafts

Book Overdrafts: Issued checks that have not cleared the bank as of December 31 result in book overdraft balances for accounting purposes which are classified within accounts payable in the accompanying consolidated balance sheets. Book overdrafts amounted to $17.5 million and $17.2 million for the year ended December 31, 2018 and 2017, respectively. The change in book overdrafts is reported as a component of financing activities within the statement of cash flows.

Insurance Reserves

Insurance Reserves: The Company is self‑insured up to certain limits for workers’ compensation, certain third‑party casualty claims, and cargo loss and damage claims. Amounts in excess of the self‑insured limits are fully insured to levels which management considers appropriate for the Company’s operations. The Company’s claims liabilities have not been discounted.

Liabilities for self‑insured workers’ compensation and third‑party casualty claims are based on the case reserve amounts plus an estimate of loss development and incurred but not reported (“IBNR”) claims, which is developed from an independent actuarial analysis. The process of determining reserve requirements utilizes historical trends and involves an evaluation of claim frequency and severity, claims management, and other factors. Case reserves are evaluated as loss experience develops and new information becomes available. Adjustments to previously estimated aggregate reserves are reflected in financial results in the periods in which they are made. Aggregate reserves represent an estimate of the costs of claims incurred, and it is possible that the ultimate liability may differ significantly from such estimates.

The Company develops an estimate of self‑insured cargo loss and damage claims liabilities based on historical trends and certain event‑specific information. Claims liabilities are recorded in accrued expenses and are not offset by insurance receivables which are reported in other accounts receivable.

Long-Term Debt

Long‑Term Debt: Long-term debt consists of borrowings outstanding under the Company’s revolving credit facility and accounts receivable securitization program, minimum principal payments due under notes payable for the financing of revenue equipment, other equipment, and software; and the present values of net minimum lease payments under capital lease obligations. The Company’s long-term debt and financing arrangements are further described in Note G.

Contingent Consideration

Contingent Consideration: The Company records the estimated fair value of contingent consideration at the acquisition date as part of the purchase price consideration for an acquisition. The fair value of the Company’s contingent consideration liability, which is further described in Note C, was determined by assessing Level 3 inputs with a discounted cash flow approach using various probability-weighted scenarios. The fair value of the outstanding contingent consideration is recorded in accrued expenses or other long-term liabilities, based on when expected payouts become due. Amounts held in escrow for contingent consideration are recorded in other current assets or other long-term assets, consistent with the classification of the related liability. The liability for contingent consideration is remeasured at each quarterly reporting period and any change in fair value as a result of the recurring assessments is recognized in operating income.

Interest Rate Swap Derivative Instruments

Interest Rate Swap Derivative Instruments: The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. The Company has interest rate swap agreements designated as a cash flow hedges. The effective portion of the gain or loss on the interest rate swap instruments is reported as unrealized gain or loss as a component of accumulated other comprehensive income or loss, net of tax, in stockholders’ equity and the change in the unrealized gain or loss on the interest rate swaps is reported in other comprehensive income or loss, net of tax, in the consolidated statements of comprehensive income. The unrealized gain or loss is reclassified out of accumulated other comprehensive loss into income in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the interest rate swap instruments, if any, is recognized in current income. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions.

Leases

Leases: The Company leases, under capital and operating lease arrangements, certain facilities, revenue equipment, and certain other equipment used primarily in Asset-Based segment service center operations. Certain of these leases contain fluctuating or escalating payments. The related rent expense is recorded on a straight‑line basis over the lease term. The cumulative excess of rent expense over rent payments is accounted for as a deferred lease obligation. For financial reporting purposes, assets held under capital leases are depreciated over their estimated useful lives on the same basis as owned assets and leasehold improvements associated with assets utilized under capital or operating leases are amortized by the straight‑line method over the shorter of the remaining lease term or the asset’s useful life. Amortization of assets under capital leases is included in depreciation expense. Obligations under the capital lease arrangements are included in long‑term debt, net of the current portion due, which is classified in current liabilities.

Nonunion Defined Benefit Pension, Supplemental Benefit, and Postretirement Health Benefit Plans

Nonunion Defined Benefit Pension, Supplemental Benefit, and Postretirement Health Benefit Plans: The Company recognizes the funded status (the difference between the fair value of plan assets and the benefit obligation) of its nonunion defined benefit pension plan, supplemental benefit plan (“SBP”), and postretirement health benefit plan in the consolidated balance sheet and recognizes changes in the funded status, net of tax, in the year in which they occur as a component of other comprehensive income or loss. Amounts recognized in other comprehensive income or loss are subsequently expensed as components of net periodic benefit cost by amortizing unrecognized net actuarial losses over the average remaining active service period of the plan participants and amortizing unrecognized prior service credits over the remaining years of service until full eligibility of the active participants at the time of the plan amendment which created the prior service credit. A corridor approach is not used for determining the amounts of net actuarial losses to be amortized.

The service cost component of net periodic benefit cost for the postretirement health benefit plan is included in operating expenses. The components of net periodic benefit cost other than service cost, including pension settlement expense, for the nonunion defined benefit pension plan, the SBP, and the postretirement health benefit plan are recorded within the other, net line item of other income (costs).

The expense and liability related to the Company’s nonunion defined benefit pension plan, SBP, and postretirement health benefit plan are measured based upon a number of assumptions and using the services of a third‑party actuary. The discount rates used to discount the plans’ obligations, and the expected rate of return applied to the fair value of plan assets for the nonunion defined benefit pension plan, impact the Company’s expense for these plans. For ongoing plans, the discount rate is determined by matching projected cash distributions with appropriate high‑quality corporate bond yields in a yield curve analysis. For the nonunion defined benefit pension plan, the Company establishes the expected rate of return on plan assets by considering the historical and expected returns for the plan’s current investment mix. Assumptions are also made regarding expected retirement age, mortality, employee turnover, and, for the postretirement health benefit plan, future increases in health care costs.

The assumptions used directly impact the net periodic benefit cost for a particular year. An actuarial gain or loss results when actual experience varies from the assumptions or when there are changes in actuarial assumptions. Actuarial gains and losses are not included in net periodic benefit cost in the period when they arise but are recognized as a component of other comprehensive income or loss and subsequently amortized as a component of net periodic benefit cost.

The Company uses December 31 as the measurement date for its nonunion defined benefit pension plan, SBP, and postretirement health benefit plan. Plan obligations are also remeasured upon curtailment and upon settlement.

The Company records quarterly pension settlement expense related to the nonunion defined benefit pension plan when qualifying distributions determined to be settlements are expected to exceed the estimated total annual interest cost of the plan. Benefit distributions under the SBP individually exceed the annual interest cost of the plan, and the Company records the related settlement expense when the amount of the benefit to be distributed is fixed, which is generally upon an employee’s termination of employment. Pension settlement expense for the nonunion defined benefit pension and SBP plans is presented in Note I.

In November 2017, an amendment was executed to terminate the nonunion defined benefit pension plan with a termination date of December 31, 2017. In September 2018, the plan received a favorable determination letter from the U.S. Internal Revenue Service (the “IRS”) regarding qualification of the plan termination. Following receipt of the determination letter, the plan’s actuarial assumptions were updated to remeasure the benefit obligation on a plan termination basis as of September 30, 2018 in connection with recognition of the quarterly pension settlement charge. The Company made assumptions for participant benefit elections, rate of return, and discount rates, including the annuity contract interest rate. These assumptions were updated as of December 31, 2018. For plan termination assumptions, the Company utilized a short-term discount rate which represents the Company’s current borrowing rate and an annuity contract interest rate based on current published rates.

The nonunion defined benefit pension plan began making lump sum distributions related to the plan termination in fourth quarter 2018. In first quarter 2019, the plan will settle remaining obligations for deferred benefits with the purchase of nonparticipating annuity contracts from insurance companies, and the Company will make a cash contribution to the plan for the amount required to fund benefit distributions and annuity contract purchases in excess of plan assets.

Revenue Recognition

Revenue Recognition: Revenues are recognized when or as control of the promised services is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services.

Asset-Based Segment

Asset-Based segment revenues consist primarily of less-than-truckload freight delivery. Performance obligations are satisfied upon final delivery of the freight to the specified destination. Revenue is recognized based on the relative transit time in each reporting period with expenses recognized as incurred. A bill-by-bill analysis is used to establish estimates of revenue in transit for recognition in the appropriate period. Because the bill-by-bill methodology utilizes the approximate location of the shipment in the delivery process to determine the revenue to recognize, management believes it to be a reliable method.

Certain contracts may provide for volume-based or other discounts which are accounted for as variable consideration. The Company estimates these amounts based on a historical expectation of discounts to be earned by customers, and revenue is recognized based on the estimates. Revenue adjustments may also occur due to rating or other billing adjustments. The Company estimates revenue adjustments based on historical information and revenue is recognized accordingly at the time of shipment. Management believes that actual amounts will not vary significantly from estimates of variable consideration.

Revenue, purchased transportation expense, and third-party service expenses are reported on a gross basis for certain shipments and services where the Company utilizes a third-party carrier for pickup, linehaul, delivery of freight, or performance of services but remains primarily responsible for fulfilling delivery to the customer and maintains discretion in setting the price for the services.

ArcBest Segment

ArcBest segment revenues consist primarily of asset-light logistics services using third-party vendors to provide transportation services. ArcBest segment revenue is generally recognized based on the relative transit time in each reporting period using estimated standard delivery times for freight in transit at the end of the reporting period. Purchased transportation expense is recognized as incurred consistent with the recognition of revenue.

Prior to the adoption of ASC Topic 606, Revenue from Contracts with Customers, on January 1, 2018, as further discussed in Adopted Accounting Pronouncements within this Note, ArcBest segment revenue was recognized based on the delivery of the shipment to the customer-designated location.

Revenue and purchased transportation expense are reported on a gross basis for shipments and services where the Company utilizes a third-party carrier for pickup and delivery but remains primarily responsible to the customer for delivery and maintains discretion in setting the price for the service.

FleetNet Segment

FleetNet segment revenues consist of service fee revenue, roadside repair revenue and routine maintenance services revenue. Service fee revenue for the FleetNet segment is recognized upon response to the service event. Repair and routine maintenance service revenue for the FleetNet segment is recognized upon completion of the service by third-party vendors.

Revenue and expense from repair and maintenance services performed by third-party vendors are reported on a gross basis as FleetNet controls the services prior to transfer to the customer and remains primarily responsible to the customer for completion of the services.

Other Recognition and Disclosure

The Company records deferred revenue when cash payments are received or due in advance of performance under the contract. Deferred revenues totaled $0.5 million and $0.6 million at December 31, 2018 and 2017, respectively, and are recorded in accrued expenses in the consolidated balance sheets.

Payment terms with customers may vary depending on the service provided, location or specific agreement with the customer. The term between invoicing and when payment is due is not significant. For certain services, payment is required before the services are provided to the customer.

The Company expenses sales commissions when incurred because the amortization period is one year or less.

The Company has elected to apply the practical expedient to not disclose the value of unsatisfied performance obligations for contracts with an original length of one year or less or contracts for which revenue is recognized at the amount to which the Company has the right to invoice for services performed.

Comprehensive Income or Loss

Comprehensive Income or Loss: Comprehensive income or loss consists of net income and other comprehensive income or loss, net of tax. Other comprehensive income or loss refers to revenues, expenses, gains, and losses that are not included in net income, but rather are recorded directly to stockholders’ equity. The Company reports the components of other comprehensive income or loss, net of tax, by their nature and discloses the tax effect allocated to each component in the consolidated statements of comprehensive income. The accumulated balance of other comprehensive income or loss is displayed separately in the consolidated statements of stockholders’ equity and the components of the balance are reported in Note J. The changes in accumulated other comprehensive income or loss, net of tax, and the significant reclassifications out of accumulated other comprehensive income or loss are disclosed, by component, in Note J. The Company elected to reclassify the stranded income tax effects resulting from the Tax Reform Act from accumulated other comprehensive loss to retained earnings as of January 1, 2018 (see Adopted Accounting Pronouncements within this Note).

Earnings Per Share

Earnings Per Share: The Company uses the two‑class method for calculating earnings per share due to certain equity awards being deemed participating securities. The two-class method is an earnings allocation method under which earnings per share is calculated for each class of common stock and participating security considering both dividends declared and participation rights in undistributed earnings as if all such earnings had been distributed during the period. The calculation uses the net income based on the two-class method and the weighted‑average number of common shares (basic earnings per share) or common equivalent shares outstanding (diluted earnings per share) during the applicable period. The dilutive effect of common stock equivalents is excluded from basic earnings per common share and included in the calculation of diluted earnings per common share.

Share-Based Compensation

Share‑Based Compensation: The fair value of restricted stock awards is determined based upon the closing market price of the Company’s common stock on the date of grant. The restricted stock units generally vest at the end of a five‑year period following the date of grant for restricted stock units awarded prior to 2018 and at the end of a four-year period following the date of grant for subsequent grants. Awards granted to non‑employee directors typically vest at the end of a one‑year period for awards granted on or after January 1, 2016 and at the end of a three‑year period for previous grants, subject to accelerated vesting due to death, disability, retirement, or change‑in‑control provisions. When restricted stock units become vested, the Company issues new shares which are subsequently distributed. Dividends or dividend equivalents are paid on certain restricted stock units during the vesting period. The Company recognizes the income tax benefits of dividends on share‑based payment awards as income tax expense or benefit in the consolidated statements of operations when awards vest or are settled.

Share‑based awards are amortized to compensation expense on a straight‑line basis over the vesting period of awards or over the period to which the recipient first becomes eligible for retirement, whichever is shorter, with vesting accelerated upon death or disability. The Company recognizes forfeitures as they occur. As a result of applying the provisions of an amendment to ASC Topic 718, Compensation – Stock Compensation, which requires the income tax effects of awards to be recognized in the statement of operations when awards vest or are settled, the Company recognized a cumulative effect adjustment to the December 31, 2016 opening balances of retained earnings, additional paid-in capital, and deferred income tax liability of $0.2 million, and $0.4 million, and $0.2 million, respectively.

Fair Value Measurements

Fair Value Measurements: The Company discloses the fair value measurements of its financial assets and liabilities. Fair value measurements for investments held in trust for the Company’s nonunion defined benefit pension plan are also disclosed. Fair value measurements are disclosed in accordance with the following hierarchy of valuation approaches based on whether the inputs of market data and market assumptions used to measure fair value are observable or unobservable:

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

Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3 – Unobservable inputs (Company’s market assumptions) that are significant to the valuation model.

Environmental Matters

Environmental Matters: The Company expenses environmental costs related to existing conditions resulting from past or current operations and from which no current or future benefit is discernible. Expenditures which extend the life of the related property or mitigate or prevent future environmental contamination are capitalized. Amounts accrued reflect management’s best estimate of the future undiscounted exposure related to identified properties based on current environmental regulations, management’s experience with similar environmental matters, and testing performed at certain sites. The estimated liability is not reduced for possible recoveries from insurance carriers or other third parties.

Exit or Disposal Activities

Exit or Disposal Activities: The Company recognizes liabilities for costs associated with exit or disposal activities when the liability is incurred.

Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Adopted

Adopted Accounting Pronouncements

ASC Topic 606, Revenue from Contracts with Customers, (“ASC Topic 606”) provides a single comprehensive revenue recognition model for all contracts with customers and contains principles to apply to determine the measurement of revenue and the timing of when it is recognized. On January 1, 2018, the Company adopted ASC Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the Company’s historic method of accounting under ASC Topic 605, Revenue Recognition, (“ASC Topic 605”). The Company’s major service lines for presentation of disaggregated revenues from contracts with customers are consistent with the Company’s reportable operating segments as presented in Note M. The primary impact of adopting ASC Topic 606 was to recognize ArcBest segment revenue over time instead of at final delivery of the shipment. As a result, revenue will generally be recorded earlier under ASC Topic 606 compared to ASC Topic 605. Asset-Based and FleetNet segment revenues were not impacted. The Company recorded a net increase to opening retained earnings of $0.4 million as of January 1, 2018 due to the cumulative impact of adopting ASC Topic 606. The impact to revenues for year ended December 31, 2018 was an increase of $0.7 million and the impact to purchased transportation expense was an increase of $0.7 million, as a result of applying ASC Topic 606.

Effective January 1, 2018, the Company adopted an amendment to ASC Topic 715, Compensation – Retirement Benefits, (“ASC Topic 715”) which requires changes to the financial statement presentation of certain components of net periodic benefit cost related to pension and other postretirement benefits accounted for under ASC Topic 715. The amendment requires the service cost component of net periodic benefit cost to continue to be included in the same line item as other compensation costs arising from services rendered by the related employees, but requires the other components of net periodic benefit cost, including pension settlement expense, to be presented separately from the service cost component and outside of the subtotal of income from operations. The provisions of the amendment are required to be applied retrospectively and were effective for the Company beginning January 1, 2018.

The Company has not incurred service cost under its nonunion defined benefit pension plan or its supplemental benefit plan (“SBP”) since the accrual of benefits under the plans was frozen on July 1, 2013 and December 31, 2009, respectively; however, the Company incurs service cost under its postretirement health benefit plan which will continue to be reported within operating expenses in the consolidated statements of operations. The other components of net periodic benefit cost (including pension settlement charges) of the nonunion defined benefit pension plan, the SBP, and the postretirement health benefit plan are reported within the other line item of other income (costs). As a result of retrospectively applying the provisions of the amendment to ASC Topic 715, $7.8 million and $5.1 million was reclassified from operating expenses to other income (costs) for the year ended December 31, 2017 and 2016, respectively. There was no change to consolidated net income or earnings per share as a result of the change in presentation under the new standard.

In February 2018, the Financial Accounting Standards Board (the “FASB”) issued an amendment to ASC Topic 220, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, (“ASC Topic 220”) which allows a reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects resulting from the Tax Reform Act. The Company early adopted this amendment for first quarter 2018 and adjusted the tax effect of items within accumulated other comprehensive income to reflect the appropriate tax rate under the Tax Reform Act in the period of adoption. As a result of applying the provisions of the amendment, the Company elected to reclassify $3.6 million of stranded income tax effects from accumulated other comprehensive loss to retained earnings as of January 1, 2018.

Effective January 1, 2018, the Company early adopted an amendment to ASC Topic 350, Intangibles – Goodwill and Other, Simplifying the Test of Goodwill Impairment, which removes Step 2 of the goodwill impairment test. For annual and interim impairment tests, the Company is required to record an impairment charge, if any, by the amount a reporting unit’s fair value is exceeded by the carrying value of the reporting unit, limited to the carrying value of goodwill included in the reporting unit. The adoption of the amendment did not have an impact on the consolidated financial statements for the year ended December 31, 2018.

The U.S. Securities and Exchange Commission issued Final Rule 33-10532, Disclosure Update and Simplification, in August 2018. The Company adopted the annual disclosure requirements of the final rule for this Annual Report on Form 10‑K for the year ended December 31, 2018 and will modify its consolidated statement of stockholders’ equity for interim periods, beginning with its first quarter 2019 Quarterly Form on 10-Q, to include changes in stockholders’ equity for each current and comparative quarterly period presented. The final rule did not have a significant impact on the Company’s financial statement disclosures.

ASC Subtopic 715-20, Compensation – Retirement Benefits – Defined Benefit Plans, was amended to eliminate certain disclosure requirements related to defined benefit plans. The Company early adopted these amendments for this Annual Report on Form 10‑K for the year ended December 31, 2018. The changes did not have a significant impact on the Company’s financial statement disclosures.

Accounting Pronouncements Not Yet Adopted

ASC Topic 842, Leases, (“ASC Topic 842”) which is effective for the Company beginning January 1, 2019, requires lessees to recognize right-of-use assets and lease liabilities for operating leases with terms greater than 12 months on the balance sheet. The standard also requires additional qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. In July 2018, the FASB issued an amendment to ASC Topic 842 which provides an optional transition method that will give companies the option to use the effective date as the date of initial application upon transition. The Company will elect this transition method and, as a result, will not adjust comparative period financial information or make the new required lease disclosures for periods before the effective date. The Company will exclude short-term leases from accounting under ASC Topic 842 and will elect the package of practical expedients upon transition that will retain lease classification and other accounting conclusions made in the assessment of existing lease contracts. Management expects the adoption of the new standard to result in a consolidated right-of-use asset and lease liability balance of approximately $60 million. This estimate does not include significant lease contracts that have been executed but not yet commenced as of January 1, 2019, which are projected to have a right-of-use asset and lease liability balance of approximately $17 million upon commencement.
