ARCBEST CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

NOTE A – ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION

ArcBest Corporation^TM (the “Company”) is the parent holding company of businesses providing integrated logistics solutions. The Company’s operations are conducted through its three reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries; ArcBest^®, the Company’s asset-light logistics operation; and FleetNet^®. References to the Company in this Quarterly Report on Form 10-Q are primarily to the Company and its subsidiaries on a consolidated basis.

The Asset-Based segment represented approximately 71% of the Company’s total revenues before other revenues and intercompany eliminations for the six months ended June 30, 2019. As of June 2019, approximately 82% of the Asset-Based segment’s employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “2018 ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which will remain in effect through June 30, 2023.

Financial Statement Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) pertaining to interim financial information. Accordingly, these interim financial statements do not include all information or footnote disclosures required by accounting principles generally accepted in the United States for complete financial statements and, therefore, should be read in conjunction with the audited financial statements and accompanying notes included in the Company’s 2018 Annual Report on Form 10-K and other current filings with the SEC. In the opinion of management, all adjustments (which are of a normal and recurring nature) considered necessary for a fair presentation have been included.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts may differ from those estimates.

Accounting Policies

The Company’s accounting policies are described in Note B to the consolidated financial statements included in Part II, Item 8 of the Company’s 2018 Annual Report on Form 10-K. The following policies have been updated during the six months ended June 30, 2019 for the adoption of accounting standard updates disclosed within this Note.

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 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. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions.

Leases: The Company leases, under finance and operating lease arrangements, certain facilities used primarily in the Asset-Based segment service center operations, certain revenue equipment used in the ArcBest segment operations, and certain other office equipment. The Company adopted Accounting Standards Codification (“ASC”) Topic 842, Leases, (“ASC Topic 842”) effective January 1, 2019. In accordance with ASC Topic 842, right-of-use assets and lease liabilities for operating leases are recorded on the balance sheet and the related lease expense is recorded on a straight-line basis over

8

the lease term in operating expenses. Included in lease expense are any variable lease payments incurred in the period that were not included in the initial lease liability. For financial reporting purposes, right-of-use assets held under finance leases are amortized over their estimated useful lives on the same basis as owned assets, and leasehold improvements associated with assets utilized under finance 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 finance leases is included in depreciation expense. Obligations under the finance lease arrangements are included in long-term debt.

The short-term lease exemption was elected under ASC Topic 842 for all classes of assets to include real property, revenue equipment, and service, office, and other equipment. The Company adopted the policy election as a lessee for all classes of assets to account for each lease component and its related non-lease component(s) as a single lease component. In determining the discount rate, the Company uses the rate implicit in the lease if that rate is readily determinable when entering into a lease as a lessee. If the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate, determined by the price of a fully collateralized loan with similar terms based on current market rates.

For contracts entered into on or after the effective date, an assessment is made as to whether the contract is, or contains, a lease at the inception of a contract. The assessment is based on: (1) whether the contract involves the use of a distinct identified asset; (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period; and (3) whether the Company has the right to direct the use of the asset. For all operating leases that meet the scope of ASC Topic 842, a right-of-use asset and a lease liability are recognized. The right-of-use asset is measured as the initial amount of the lease liability, plus any initial direct costs incurred, less any prepayments prior to commencement or lease incentives received. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s secured incremental borrowing rate for the same term as the underlying lease. Lease payments included in the measurement of the lease liability are comprised of the following: (1) the fixed noncancelable lease payments, (2) payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and (3) payments for early termination options unless it is reasonably certain the lease will not be terminated early. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement and included in the measurement of the initial lease liability. Additional payments based on the change in an index or rate are recorded as a period expense when incurred. Lease modifications result in remeasurement of the lease liability.

Adopted Accounting Pronouncements

ASC Topic 842, which was adopted by the Company effective 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. The Company elected the modified retrospective method of applying the transition provisions at the beginning of the period of adoption and, as a result, has not adjusted comparative period financial information and has not included the new lease disclosures for periods before the effective date. Prior period amounts continue to be reported under the Company’s historical accounting in accordance with the previous lease guidance included in ASC Topic 840.

The Company has excluded short-term leases from accounting under ASC Topic 842 and has elected the package of practical expedients as permitted under the transition guidance, which allowed the Company to not reassess: (1) whether contracts are, or contain, leases; (2) lease classification; and (3) capitalization of initial direct costs. For contracts entered into on or after the effective date, an assessment is made as to whether the contract is, or contains, a lease at the inception of a contract. Consistent with the package of practical expedients elected, leases entered into prior to January 1, 2019, are accounted for under ASC Topic 840 and were not reassessed. For all classes of assets, the policy election was made to account for each lease component and its related non-lease component(s) as a single lease component. The election to not recognize right-of-use assets and lease liabilities for short-term leases that have a term of 12 months or less did not have a material effect on the right-of-use assets and lease liabilities.

The majority of the Company’s lease portfolio consists of real property operating leases related to facilities used in the Asset-Based segment service center operations. The lease portfolio also includes operating leases related to certain revenue equipment used in the ArcBest segment operations as well as a small number of office equipment finance leases. Management has recorded the right-of-use assets and associated lease liabilities for operating leases on the consolidated

9

balance sheet as of June 30, 2019 in accordance with ASC Topic 842. Finance leases are not material to the consolidated financial statements.

The most significant impact of adopting ASC Topic 842 was the recognition of right-of-use assets and lease liabilities on the balance sheet for operating leases of $58.7 million as of January 1, 2019. The accounting for finance leases (formerly referred to as capital leases prior to the adoption of ASC Topic 842) remained substantially unchanged. The expense recognition for operating leases and finance leases under ASC Topic 842 is substantially consistent with ASC Topic 840 and the impact of the new standard is non-cash in nature. As a result, there is no significant impact on the Company’s results of operations or cash flows presented in the Company’s consolidated financial statements.

ASC Topic 815, Derivatives and Hedging, which was adopted by the Company on January 1, 2019, was amended to change the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results to simplify hedge accounting treatment and better align an entity’s risk management activities and financial reporting for hedging relationships. ASC Topic 815, as amended, also allows for the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a U.S. benchmark interest rate. The amendment did not have an impact on the consolidated financial statements.

The U.S. Securities and Exchange Commission (the “SEC”) issued Final Rule 33-10618, FAST Act Modernization and Simplification of Regulation S-K, (“Final Rule 33-10618”) in March 2019 to modernize and simplify certain disclosure requirements in Regulation S-K and the related rules and forms. Effective April 2, 2019, the final rule allows registrants to redact confidential information from most exhibits filed with the SEC without filing a confidential treatment request. Effective May 2, 2019, the final rule requires registrants to include the trading symbol for each class of registered securities on the cover page of certain SEC forms. The eXtensible Business Reporting Language (“XBRL”) reporting requirements of the final rule for tagging data on the cover page of certain SEC filings and the use of hyperlinks for information that is incorporated by reference and available on EDGAR became effective for the Company with this Quarterly Report on Form 10-Q.

Accounting Pronouncements Not Yet Adopted

Final Rule 33-10618 includes certain provisions to simplify certain annual disclosure requirements within the Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), Risk Factors, and Properties sections of Form 10-K. These provisions, which the Company will adopt for its 2019 Annual Report on Form 10-K, are not expected to have a significant impact on the Company’s consolidated financial statement disclosures.

ASC Subtopic 350-40, Intangibles – Goodwill and Other – Internal-Use Software: Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, (“ASC Subtopic 350-40”) was amended by the FASB in August 2018 and is effective for the Company beginning January 1, 2020. The amendments to ASC Subtopic 350-40 clarify the accounting treatment for implementation costs incurred by the customer in a cloud computing software arrangement. The amendments allow implementation costs of cloud computing arrangements to be capitalized using the same method prescribed by ASC Subtopic 350-40, Internal-Use Software. The amendments to ASC Subtopic 350-40 will be adopted on a prospective basis and are not expected to have an impact on the Company’s consolidated financial statements.

ASC Topic 820, Fair Value Measurement, was amended to modify the disclosure requirements of fair value measurements, primarily impacting the disclosures for Level 3 fair value measurements. The amendment is effective for the Company beginning January 1, 2020 and is not expected to have a significant impact on the Company’s financial statement disclosures.

ASC Topic 326, Financial Instruments – Credit Losses, (“ASC Topic 326”), was amended to improve the measurement of credit losses on financial instruments, including trade accounts receivable. The amendment is effective for the Company beginning January 1, 2020 and is not expected to have a significant impact on the Company’s consolidated financial statements.

Management believes there is no other new accounting guidance issued but not yet effective that is relevant to the Company’s current financial statements.

(1) Recorded at cost plus accrued interest, which approximates fair value.

(2) Amounts may be redeemed on a daily basis with the original issuer.

(3) Recorded at fair value as determined by quoted market prices (see amounts presented in the table of financial assets and liabilities measured at fair value within this Note).

(4) Recorded at amortized cost plus accrued interest, which approximates fair value. U.S. Treasury securities with a maturity date within 90 days of the purchase date are classified as cash equivalents. U.S. Treasury securities included in short-term investments are held-to-maturity investments with maturity dates of less than one year.

The Company’s long-term financial instruments are presented in the table of financial assets and liabilities measured at fair value within this Note.

Concentrations of Credit Risk of Financial Instruments

The Company is potentially subject to concentrations of credit risk related to its cash, cash equivalents, and short-term investments. The Company reduces credit risk by maintaining its cash deposits primarily in FDIC-insured accounts and placing its short-term investments primarily in FDIC-insured certificates of deposit. However, certain cash deposits and certificates of deposit may exceed federally insured limits. At June 30, 2019 and December 31, 2018, cash, cash equivalents, and short-term investments totaling $68.9 million and $94.7 million, respectively, were neither FDIC insured nor direct obligations of the U.S. government.

Fair Value Disclosure of Financial Instruments

Fair value disclosures are made in accordance with the following hierarchy of valuation techniques 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.

	$	282,054	$	285,456	$	291,409	$	291,560

(1) The revolving credit facility (the “Credit Facility”) carries a variable interest rate based on LIBOR, plus a margin, that is considered to be priced at market for debt instruments having similar terms and collateral requirements (Level 2 of the fair value hierarchy).

(2) Borrowings under the Company’s accounts receivable securitization program carry a variable interest rate based on LIBOR, plus a margin. The borrowings are considered to be priced at market for debt instruments having similar terms and collateral requirements (Level 2 of the fair value hierarchy).

(3) Fair value of the notes payable was determined using a present value income approach based on quoted interest rates from lending institutions with which the Company would enter into similar transactions (Level 2 of the fair value hierarchy).

Included in other long-term assets, with a corresponding liability reported within other long-term liabilities.

(3) Included in other long-term assets or other long-term liabilities. The fair values of the interest rate swaps were determined by discounting future cash flows and receipts based on expected interest rates observed in market interest rate curves adjusted for estimated credit valuation considerations reflecting nonperformance risk of the Company and the counterparty, which are considered to be in Level 3 of the fair value hierarchy. The Company assessed Level 3 inputs as insignificant to the valuation at June 30, 2019 and December 31, 2018 and considers the interest rate swap valuations in Level 2 of the fair value hierarchy.

(4) Included in accrued expenses. At December 31, 2018, the fair value of the contingent consideration for an earn-out agreement related to the September 2016 acquisition of LDS represents the final accrued payment and was based on calculations performed for the earn-out period which ended August 31, 2018. In January 2019, final payment of the contingent consideration was released from an escrow account reported in other current assets in the consolidated balance sheets.

NOTE C – GOODWILL AND INTANGIBLE ASSETS

Goodwill represents the excess of cost over the fair value of net identifiable tangible and intangible assets acquired. Goodwill by reportable operating segment consisted of $107.7 million and $0.6 million reported in the ArcBest and FleetNet segments, respectively, for both June 30, 2019 and December 31, 2018.

NOTE D – INCOME TAXES

On December 22, 2017, H.R. 1/Public Law 115-97 which includes tax legislation titled Tax Cuts and Jobs Act (the “Tax Reform Act”) was signed into law. Effective January 1, 2018, the Tax Reform Act reduced the U.S. federal corporate tax rate from 35% to 21%. As a result of the Tax Reform Act, the Company recorded a provisional reduction of net deferred income tax liabilities of approximately $24.5 million at December 31, 2017, pursuant to the provisions of ASC Topic 740, Income Taxes, which requires the impact of tax law changes to be recognized in the period in which the legislation is enacted. An additional provisional reduction of net deferred income tax liabilities of $0.1 million and $2.6 million was recognized in the three and six months ended June 30, 2018, respectively, related to the reversal of temporary differences through the Company’s fiscal tax year end of February 28, 2018. State tax rates vary among states and average approximately 6.0% to 6.5%, although some state rates are higher and a small number of states do not impose an income tax. The effective tax rate was 27.4% and 27.1% for the three and six months ended June 30, 2019, respectively, and the effective tax benefit rate was 68.0% and 15.0% for the three and six months ended June 30, 2018, respectively.

In addition to the provisional effect on net deferred tax liabilities, the Company recorded a provisional reduction in current income tax expense of $1.3 million and $0.1 million at December 31, 2017 and June 30, 2018, respectively, as a result of the Tax Reform Act, to reflect the Company’s use of a fiscal year rather than a calendar year for U.S. income tax filing. Due to the fact that the Company’s fiscal tax year included the effective date of the rate change under the Tax Reform Act, taxes were required to be calculated by applying a blended rate to the taxable income for the taxable year ended February 28, 2018. The blended rate is calculated based on the ratio of days in the fiscal year prior to and after the effective date of the rate change. In computing total tax expense for the three and six months ended June 30, 2018, a 32.74% blended federal statutory rate was applied to the two months ended February 28, 2018, and a 21.0% federal statutory rate was

14

applied to the months of March 2018 through June 2018. A federal statutory rate of 21.0% was applied to the three and six months ended June 30, 2019.

The accounting for the income tax effects of the Tax Reform Act was completed as of December 31, 2018, and all amounts recorded were considered final.

For the three and six months ended June 30, 2019, the difference between the Company’s effective tax rate and the federal statutory rate primarily resulted from state income taxes, nondeductible expenses, changes in the cash surrender value of life insurance, and tax expense from the vesting of stock awards. For the six months ended June 30, 2018, the difference between the Company’s effective tax rate and the federal statutory rate primarily resulted from the $2.6 million provisional reduction of net deferred income tax liabilities, as previously discussed, and the $1.2 million alternative fuel tax credit related to the year ended December 31, 2017 which was recognized in first quarter 2018 due to the February 2018 passage of the Bipartisan Budget Act of 2018 which retroactively reinstated the alternative fuel tax credit that had previously expired on December 31, 2016. The difference between the Company’s effective tax rate and the federal statutory rate for the three and six months ended June 30, 2018 also resulted from state income taxes, nondeductible expenses, changes in tax valuation allowances, the tax benefit from the vesting of stock awards, and changes in the cash surrender value of life insurance.

As of June 30, 2019, the Company’s deferred tax liabilities, which will reverse in future years, exceeded the deferred tax assets. The Company evaluated the total deferred tax assets at June 30, 2019 and concluded that, other than for certain deferred tax assets related to state contribution carryforwards, the assets did not exceed the amount for which realization is more likely than not. In making this determination, the Company considered the future reversal of existing taxable temporary differences, future taxable income, and tax planning strategies. Valuation allowances for deferred tax assets totaled $0.1 million at June 30, 2019 and December 31, 2018.

The Company had reserves for uncertain tax positions of $1.0 million at June 30, 2019 and December 31, 2018.

In first quarter of 2019, the Company recorded a deferred tax asset of approximately $19.0 million related to operating lease liabilities and recorded a deferred tax liability of approximately $19.0 million related to operating lease right-of-use assets due to the adoption of ASC Topic 842.

The Company paid federal, state, and foreign income taxes of $8.9 million during the six months ended June 30, 2019, and paid $2.5 million of foreign and state income taxes during the six months ended June 30, 2018. The Company received refunds of less than $0.1 million of state income taxes and refunds of $1.1 million of federal and state income taxes that were paid in prior years during the six months ended June 30, 2019 and 2018, respectively.

NOTE E – LEASES

The Company leases, under finance and operating lease arrangements, certain facilities used primarily in the Asset-Based segment service center operations, certain revenue equipment used in the ArcBest segment operations, and certain other office equipment. Operating leases have remaining terms of less than 10 years, some of which include one or more options to renew, with renewal option terms up to five years, and some of which include options to terminate the leases within the next three years. The right-of-use assets and lease liabilities as of June 30, 2019 do not assume the option to early terminate any of the Company’s leases, and all renewal options that have been exercised or are reasonably certain to be exercised as of June 30, 2019 are included in the right-of-use assets and lease liabilities. Variable lease cost for operating leases consists of subsequent changes in CPI index, rent payments that are based on usage, and other lease related payments subject to change and not considered fixed payments. All fixed lease and non-lease component payments are combined in determining the right-of-use asset and lease liability.

The Company has a small number of finance leases recorded in property, plant and equipment and long-term debt related to structures and office equipment that are immaterial to the consolidated financial statements.

Financing Arrangements

Credit Facility

The Company has a revolving credit facility (the “Credit Facility”) under its Second Amended and Restated Credit Agreement (the “Credit Agreement”) with an initial maximum credit amount of $200.0 million, including a swing line facility in an aggregate amount of up to $20.0 million and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $20.0 million. The Company may request additional revolving commitments or incremental term loans thereunder up to an aggregate additional amount of $100.0 million, subject to certain additional conditions as provided in the Credit Agreement. As of June 30, 2019, the Company had available borrowing capacity of $130.0 million under the Credit Facility.

Principal payments under the Credit Facility are due upon maturity of the facility on July 7, 2022; however, borrowings may be repaid, at the Company’s discretion, in whole or in part at any time, without penalty, subject to required notice periods and compliance with minimum prepayment amounts. Borrowings under the Credit Agreement can either be, at the Company’s election: (i) at an alternate base rate (as defined in the Credit Agreement) plus a spread; or (ii) at a Eurodollar rate (as defined in the Credit Agreement) plus a spread. The applicable spread is dependent upon the Company’s Adjusted Leverage Ratio (as defined in the Credit Agreement). The Credit Agreement contains conditions, representations and

18

warranties, events of default, and indemnification provisions that are customary for financings of this type, including, but not limited to, a minimum interest coverage ratio, a maximum adjusted leverage ratio, and limitations on incurrence of debt, investments, liens on assets, certain sale and leaseback transactions, transactions with affiliates, mergers, consolidations, purchases and sales of assets, and certain restricted payments. The Company was in compliance with the covenants under the Credit Agreement at June 30, 2019.

Interest Rate Swaps

The Company has a five-year interest rate swap agreement with a $50.0 million notional amount maturing on January 2, 2020. The Company receives floating-rate interest amounts based on one-month LIBOR in exchange for fixed-rate interest payments of 1.85% over the life of the agreement. The interest rate swap mitigates interest rate risk by effectively converting $50.0 million of borrowings under the Credit Facility from variable-rate interest to fixed-rate interest with a per annum rate of 3.10% based on the margin of the Credit Facility as of June 30, 2019. The fair value of the interest rate swap of $0.1 million and $0.3 million was recorded in other long-term assets in the consolidated balance sheet at June 30, 2019 and December 31, 2018, respectively.

In June 2017, the Company entered into a forward-starting interest rate swap agreement with a $50.0 million notional amount which will start on January 2, 2020 upon maturity of the current interest rate swap agreement, and mature on June 30, 2022. The Company will receive floating-rate interest amounts based on one-month LIBOR in exchange for fixed-rate interest payments of 1.99% over the life of the agreement. The interest rate swap mitigates interest rate risk by effectively converting $50.0 million of borrowings under the Credit Facility from variable-rate interest to fixed-rate interest with a per annum rate of 3.24% based on the margin of the Credit Facility as of June 30, 2019. The fair value of the interest rate swap of $0.5 million was recorded in other long-term liabilities and $0.5 million was recorded in other long-term assets in the consolidated balance sheet at June 30, 2019 and December 31, 2018, respectively.

The unrealized gain on the interest rate swap instruments was reported as a component of accumulated other comprehensive loss, net of tax, in stockholders’ equity at June 30, 2019 and December 31, 2018, and the change in the unrealized income on the interest rate swaps for the three months and six months ended June 30, 2019 and 2018 was reported in other comprehensive loss, net of tax, in the consolidated statements of comprehensive income. The interest rate swaps are subject to certain customary provisions that could allow the counterparty to request immediate settlement of the fair value liability or asset upon violation of any or all of the provisions. The Company was in compliance with all provisions of the interest rate swap agreements at June 30, 2019.

Accounts Receivable Securitization Program

The Company’s accounts receivable securitization program, which matures on October 1, 2021, allows for cash proceeds of $125.0 million to be provided under the program and has an accordion feature allowing the Company to request additional borrowings up to $25.0 million, subject to certain conditions. Under this program, certain subsidiaries of the Company continuously sell a designated pool of trade accounts receivables to a wholly owned subsidiary which, in turn, may borrow funds on a revolving basis. This wholly owned consolidated subsidiary is a separate bankruptcy-remote entity, and its assets would be available only to satisfy the claims related to the lender’s interest in the trade accounts receivables. Borrowings under the accounts receivable securitization program bear interest based upon LIBOR, plus a margin, and an annual facility fee. The securitization agreement contains representations and warranties, affirmative and negative covenants, and events of default that are customary for financings of this type, including a maximum adjusted leverage ratio covenant. As of June 30, 2019, $40.0 million was borrowed under the program. The Company was in compliance with the covenants under the accounts receivable securitization program at June 30, 2019.

The accounts receivable securitization program includes a provision under which the Company may request and the letter of credit issuer may issue standby letters of credit, primarily in support of workers’ compensation and third-party casualty claims liabilities in various states in which the Company is self-insured. The outstanding standby letters of credit reduce the availability of borrowings under the program. As of June 30, 2019, standby letters of credit of $14.9 million have been issued under the program, which reduced the available borrowing capacity to $70.1 million.

19

Letter of Credit Agreements and Surety Bond Programs

As of June 30, 2019, the Company had letters of credit outstanding of $15.5 million (including $14.9 million issued under the accounts receivable securitization program). The Company has programs in place with multiple surety companies for the issuance of surety bonds in support of its self-insurance program. As of June 30, 2019, surety bonds outstanding related to the self-insurance program totaled $48.6 million.

Notes Payable

The Company has financed the purchase of certain revenue equipment, other equipment, and software through promissory note arrangements, including $20.5 million for revenue equipment and other equipment during the three months ended June 30, 2019.

Subsequent to June 30, 2019, the Company financed the purchase of an additional $17.2 million of revenue equipment through promissory note arrangements as of August 1, 2019.

Nonunion Defined Benefit Pension Plan

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 IRS regarding qualification of the plan termination. Benefit election forms were provided to plan participants during the fourth quarter of 2018 and participants could elect any form of payment allowed by the plan for immediate commencement of payment or defer payment until a later date. The plan began distributing immediate lump sum benefit payments related to the plan termination in fourth quarter 2018 and continued making these distributions during 2019. The plan received an extension from the Pension Benefit Guaranty Corporation (the “PBGC”) to allow additional time for the plan to administer the settlement of the remaining obligation for deferred benefits through the purchase of a nonparticipating annuity contract from an insurance company. The Company will make a cash contribution to the plan for the amount, if any, required to fund benefit distributions and annuity contract purchases in excess of plan assets.

The Company recognized pension settlement expense as a component of net periodic benefit cost of the nonunion defined benefit pension plan for the three and six months ended June 30, 2019 of $0.3 million (pre-tax), or $0.2 million (after-tax), and $1.6 million (pre-tax), or $1.2 million (after-tax), respectively, related to $3.0 million and $17.9 million of lump-sum benefit distributions from the plan for the three and six months ended June 30, 2019, respectively. For the three and six months ended June 30, 2018, pension settlement expense of $0.4 million (pre-tax), or $0.3 million (after-tax), and $1.1 million (pre-tax), or $0.8 million (after-tax), respectively, was recognized related to $3.7 million and $8.5 million of lump-sum distributions from the plan for the three and six months ended June 30, 2018, respectively. Pension settlement charges related to the plan termination, including those related to an annuity contract purchase are expected to occur in 2019.

In August 2019, the nonunion defined benefit pension plan received a preliminary bid for a nonparticipating annuity contract from an insurance company to settle the pension obligation related to the vested benefits of the remaining participants who were receiving monthly benefit payments from the plan or who did not elect to receive a lump sum benefit upon plan termination. Based on the most recently available actuarial information, including the preliminary bid received in August, nonunion pension settlement expense for the second half of 2019 is estimated to be approximately $2.0 million, or $1.5 million after-tax, and the Company could expect to make a cash contribution to the plan of approximately $7.0 million, which would be deductible for income tax purposes, to fund an annuity contract purchase and the remaining benefit distributions expected to be made from the plan in excess of plan assets. However, there can be no assurances in regards to the required cash funding or pension settlement charges, as the actual amounts are dependent on various factors and will be determined using updated actuarial data. Liquidation of plan assets and settlement of plan obligations for the nonunion defined benefit pension plan is expected to be completed in 2019.

The Company’s short-term rate of return assumption, net of estimated expenses expected to be paid from plan assets, utilized in determining nonunion defined benefit pension expense was lowered from 1.4% for first quarter 2019 to 0.0% for the second and third quarters of 2019, as estimated expenses expected to be paid from plan assets are expected to offset investment returns on plan assets which were held in money market mutual funds as of June 30, 2019.

The following table discloses the changes in benefit obligations and plan assets of the nonunion defined benefit pension plan for the six months ended June 30, 2019:

	Nonunion Defined

(1) The plan recognized an actuarial gain on lump-sum distributions related to benefit elections for plan termination which had been included in the actuarial estimate for the annuity contract purchase as of the December 31, 2018 measurement date.

(2) Recognized within current portion of pension and postretirement liabilities in the accompanying consolidated balance sheet at June 30, 2019.

Multiemployer Plans

ABF Freight System, Inc. and certain other subsidiaries reported in the Company’s Asset-Based operating segment (“ABF Freight”) contribute to multiemployer pension and health and welfare plans, which have been established pursuant to the Taft-Hartley Act, to provide benefits for its contractual employees. ABF Freight’s contributions generally are based on the time worked by its contractual employees, in accordance with the 2018 ABF NMFA and other related supplemental agreements. ABF Freight recognizes as expense the contractually required contributions for each period and recognizes as a liability any contributions due and unpaid.

The 25 multiemployer pension plans to which ABF Freight contributes vary greatly in size and in funded status. Contribution obligations to these plans are generally specified in the 2018 ABF NMFA, which will remain in effect through June 30, 2023. The funding obligations to the pension plans are intended to satisfy the requirements imposed by the Pension Protection Act of 2006, which was permanently extended by the Multiemployer Pension Reform Act (the “Reform Act”) included in the Consolidated and Further Continuing Appropriations Act of 2015. Provisions of the Reform Act include, among others, providing qualifying plans the ability to self-correct funding issues, subject to various requirements and restrictions, including applying to the U.S. Department of the Treasury for the reduction of certain accrued benefits. Through the term of its current collective bargaining agreement, ABF Freight’s contribution obligations generally will be satisfied by making the specified contributions when due. However, the Company cannot determine with any certainty the contributions that will be required under future collective bargaining agreements for ABF Freight’s contractual employees. If ABF Freight was to completely withdraw from certain multiemployer pension plans, under current law, ABF Freight would have material liabilities for its share of the unfunded vested liabilities of each such plan.

22

Approximately one half of ABF Freight’s total contributions to multiemployer pension plans are made to the Central States, Southeast and Southwest Areas Pension Plan (the “Central States Pension Plan”). As set forth in the 2018 Annual Funding Notice for the Central States Pension Plan, the funded percentage of the plan was 27.2% as of January 1, 2018. ABF Freight received a Notice of Critical and Declining Status for the Central States Pension Plan dated March 29, 2019, in which the plan’s actuary certified that, as of January 1, 2019, the plan is in critical and declining status, as defined by the Reform Act. Critical and declining status is applicable to critical status plans that are projected to become insolvent anytime within the next 14 plan years, or if the plan is projected to become insolvent within the next 19 plan years and either the plan’s ratio of inactive participants to active participants exceeds two to one or the plan’s funded percentage is less than 80%.

As more fully described in Note I to the consolidated financial statements in Item 8 of the Company’s 2018 Annual Report on Form 10-K, ABF Freight’s multiemployer pension plan obligation with the New England Teamsters and Trucking Industry Pension Fund (the “New England Pension Fund”) was restructured under a transition agreement effective on August 1, 2018, which resulted in a related withdrawal liability for which ABF Freight recognized a one-time charge of $37.9 million (pre-tax) as of June 30, 2018. In accordance with the transition agreement, ABF Freight made an initial lump sum cash payment of $15.1 million in third quarter 2018 and the remainder of the withdrawal liability, which had an initial aggregate present value of $22.8 million, will be settled with monthly payments to the New England Pension Fund over a period of 23 years. In accordance with current tax law, these payments are deductible for income taxes when paid.

As of June 30, 2019, the outstanding withdrawal liability totaled $22.3 million, of which $0.6 million and $21.7 million was recorded in accrued expenses and other long-term liabilities, respectively. The fair value of the obligation was $24.4 million at June 30, 2019, which is equal to the present value of the future withdrawal liability payments, discounted at a 3.6% interest rate determined using the 20-year U.S. Treasury rate plus a spread (Level 2 of the fair value hierarchy).

The multiemployer plan administrators have provided to the Company no other significant changes in information related to multiemployer plans from the information disclosed in the Company’s 2018 Annual Report on Form 10-K.

Earnings per common share	$	0.92	$	0.05	$	1.10	$	0.42

Under the two-class method of calculating earnings per share, dividends paid and a portion of undistributed net income, but not losses, are allocated to unvested RSUs that receive dividends, which are considered participating securities. Beginning with 2015 grants, the RSU agreements were modified to remove dividend rights; therefore, the RSUs granted subsequent to 2015 are not participating securities. For the three- and six-month periods ended June 30, 2019 and 2018, outstanding stock awards of 0.2 million and 0.1 million, respectively, were not included in the diluted earnings per share calculation because their inclusion would have the effect of increasing the earnings per share.

NOTE K – OPERATING SEGMENT DATA

The Company uses the “management approach” to determine its reportable operating segments, as well as to determine the basis of reporting the operating segment information. The management approach focuses on financial information that the Company’s management uses to make operating decisions. Management uses revenues, operating expense categories, operating ratios, operating income, and key operating statistics to evaluate performance and allocate resources to the Company’s operations.

Shared services represent costs incurred to support all segments, including sales, pricing, customer service, marketing, capacity sourcing functions, human resources, financial services, information technology, legal, and other company-wide services. Certain overhead costs are not attributable to any segment and remain unallocated in “Other and eliminations.” Included in unallocated costs are expenses related to investor relations, legal, the ArcBest Board of Directors, and certain technology investments. Shared services costs attributable to the operating segments are predominantly allocated based upon estimated and planned resource utilization-related metrics such as estimated shipment levels, number of pricing proposals, or number of personnel supported. The bases for such charges are modified and adjusted by management when necessary or appropriate to reflect fairly and equitably the actual incidence of cost incurred by the operating segments. Management believes the methods used to allocate expenses are reasonable.

26

The Company’s reportable operating segments are impacted by seasonal fluctuations which affect tonnage, shipment or service event levels, and demand for services, as described below; therefore, operating results for the interim periods presented may not necessarily be indicative of the results for the fiscal year.

The Company’s reportable operating segments are as follows:

● The Asset-Based segment includes the results of operations of ABF Freight System, Inc. and certain other subsidiaries. The segment operations include national, inter-regional, and regional transportation of general commodities through standard, expedited, and guaranteed LTL services. In addition, the segment operations include freight transportation related to certain consumer household goods self-move services.

Freight shipments and operating costs of the Asset-Based segment can be adversely affected by inclement weather conditions. The second and third calendar quarters of each year usually have the highest tonnage levels while the first quarter generally has the lowest, although other factors, including the state of the U.S. and global economies, may influence quarterly freight tonnage levels.

● The ArcBest segment includes the results of operations of the Company’s service offerings in ground expedite, truckload, truckload-dedicated, intermodal, household goods moving, managed transportation, warehousing and distribution, and international freight transportation for air, ocean, and ground.

ArcBest segment operations are influenced by seasonal fluctuations that impact customers’ supply chains. The second and third calendar quarters of each year usually have the highest shipment levels while the first quarter generally has the lowest, although other factors, including the state of the U.S. and global economies and available capacity in the market, may impact quarterly business levels. Shipments of the ArcBest segment may decline during winter months because of post-holiday slowdowns, but expedite shipments can be subject to short-term increases depending on the impact of weather disruptions to customers’ supply chains. Plant shutdowns during summer months may affect shipments for automotive and manufacturing customers of the ArcBest segment, but severe weather events can result in higher demand for expedite services. Moving services of the ArcBest segment are impacted by seasonal fluctuations, generally resulting in higher business levels in the second and third quarters as the demand for moving services is typically stronger in the summer months.

● FleetNet includes the results of operations of FleetNet America, Inc. and certain other subsidiaries that provide roadside assistance and maintenance management services for commercial vehicles through a network of third-party service providers. FleetNet also provides services to the Asset-Based and ArcBest segments. Approximately 19% and 16% of FleetNet’s revenues for the three and six months ended June 30, 2019, respectively, are for services provided to the Asset-Based and ArcBest segments compared to approximately 3% for the same periods of 2018.

Emergency roadside service events of the FleetNet segment are favorably impacted by extreme weather conditions that affect commercial vehicle operations, and the segment’s results of operations will be influenced by seasonal variations in service event volume.

The Company’s other business activities and operating segments that are not reportable include ArcBest Corporation and certain other subsidiaries. Certain costs incurred by the parent holding company and the Company’s shared services subsidiary are allocated to the reporting segments. The Company eliminates intercompany transactions in consolidation. However, the information used by the Company’s management with respect to its reportable segments is before intersegment eliminations of revenues and expenses.

Further classifications of operations or revenues by geographic location are impracticable and, therefore, are not provided. The Company’s foreign operations are not significant.

NOTE L – LEGAL PROCEEDINGS, ENVIRONMENTAL MATTERS, AND OTHER EVENTS

The Company is involved in various legal actions arising in the ordinary course of business. The Company maintains liability insurance against certain risks arising out of the normal course of its business, subject to certain self-insured retention limits. The Company routinely establishes and reviews the adequacy of reserves for estimated legal, environmental, and self-insurance exposures. While management believes that amounts accrued in the consolidated financial statements are adequate, estimates of these liabilities may change as circumstances develop. Considering amounts recorded, routine legal matters are not expected to have a material adverse effect on the Company’s financial condition, results of operations, or cash flows.

29

Environmental Matters

The Company’s subsidiaries store fuel for use in tractors and trucks in 61 underground tanks located in 18 states. Maintenance of such tanks is regulated at the federal and, in most cases, state levels. The Company believes it is in substantial compliance with all such regulations. The Company’s underground storage tanks are required to have leak detection systems. The Company is not aware of any leaks from such tanks that could reasonably be expected to have a material adverse effect on the Company.

The Company has received notices from the Environmental Protection Agency and others that it has been identified as a potentially responsible party under the Comprehensive Environmental Response Compensation and Liability Act, or other federal or state environmental statutes, at several hazardous waste sites. After investigating the Company’s involvement in waste disposal or waste generation at such sites, the Company has either agreed to de minimis settlements or determined that its obligations, other than those specifically accrued with respect to such sites, would involve immaterial monetary liability, although there can be no assurances in this regard.

At June 30, 2019 and December 31, 2018, the Company’s reserve, which was reported in accrued expenses, for estimated environmental cleanup costs of properties currently or previously operated by the Company totaled $0.6 million. 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.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

General

ArcBest Corporation^TM (together with its subsidiaries, the “Company,” “we,” “us,” and “our”) provides a comprehensive suite of freight transportation services and integrated logistics solutions. Our operations are conducted through our three reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries (“ABF Freight”); ArcBest^®, our asset-light logistics operation; and FleetNet^®. The ArcBest and the FleetNet reportable segments combined represent our Asset-Light operations. References to the Company, including “we,” “us,” and “our,” in this Quarterly Report on Form 10-Q are primarily to the Company and its subsidiaries on a consolidated basis.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) describes the principal factors affecting our results of operations, liquidity and capital resources, and critical accounting policies. This discussion should be read in conjunction with the accompanying quarterly unaudited consolidated financial statements and the related notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q and with our Annual Report on Form 10-K for the year ended December 31, 2018. Our 2018 Annual Report on Form 10-K includes additional information about significant accounting policies, practices, and the transactions that underlie our financial results, as well as a detailed discussion of the most significant risks and uncertainties to which our financial and operating results are subject.

(1) ABF Freight recorded a one-time $37.9 million pre-tax charge in second quarter 2018 for the multiemployer pension plan withdrawal liability resulting from the transition agreement with the New England Pension Fund.

31

Our consolidated revenues, which totaled $771.5 million and $1,483.3 million for the three and six months ended June 30, 2019, respectively, decreased 2.8% and 0.7% compared to the same prior-year periods. The decreases in consolidated revenues reflect a 5.6% and 3.6% decrease in revenues of our Asset-Light operations (representing the combined operations of our ArcBest and FleetNet segments), partially offset by a 0.1% and 2.3% increase in our Asset-Based revenues for the three and six months ended June 30, 2019, respectively, compared to the same prior-year periods. Our Asset-Based revenue growth was impacted by a 4.1% and 5.9% improvement in yield, as measured by billed revenue per hundredweight, including fuel surcharges, for the three- and six-month periods ended June 30, 2019, respectively, versus the same periods of 2018, partially offset by decreases in total tonnage per day of 3.4% and 3.3%, respectively, primarily due to declines in shipment levels and weight per shipment. The decline in revenues of our Asset-Light operations for the three and six months ended June 30, 2019, compared to the same periods of 2018, is primarily due to decreases in revenue per shipment of 9.8% and 8.3%, respectively, and declines in shipments per day of 1.6% and 1.3%, respectively, for the ArcBest segment, associated with lower market prices and more available capacity in the truckload market compared to the prior-year periods, partially offset by revenue improvement for the FleetNet segment on higher service event volume. On a combined basis, the Asset-Light operating segments generated approximately 29% and 30% of our total revenues before other revenues and intercompany eliminations for the three and six months ended June 30, 2019, respectively.

For the three and six months ended June 30, 2019, consolidated operating income totaled $35.2 million and $43.8 million, compared to $3.2 million and $15.9 million, respectively, for the same periods of 2018. Our operating results for the three and six months ended June 30, 2018 were impacted by a one-time charge of $37.9 million (pre-tax), or $28.2 million (after-tax) and $1.05 per diluted share for the three-month period ended June 30, 2018, recorded by ABF Freight in second quarter 2018 for a multiemployer pension plan withdrawal liability resulting from the transition agreement with the New England Teamsters and Trucking Industry Pension Fund (the “New England Pension Fund”), as further discussed within the Asset-Based Segment Overview section of Results of Operations. Excluding the impact of this one-time charge, our consolidated operating results for the three and six months ended June 30, 2019, compared to the same prior-year periods, declined primarily due to the lower revenues previously described combined with the matters further described within the discussions of segment results, including business mix changes and expense impacts. Restructuring charges related to the realignment of our organizational structure of $0.3 million and $0.7 million were reported on a consolidated basis for the three and six months ended June 30, 2018, respectively, with no comparable costs recognized during the same periods of 2019.

The loss reported in the “Other and eliminations” line, which totaled $4.1 million and $12.4 million for the three and six months ended June 30, 2019, respectively, compared to $5.0 million and $10.3 million for the same periods of 2018, includes expenses related to investments to develop and design various ArcBest technology and innovations as well as expenses related to shared services for the delivery of comprehensive transportation and logistics services to ArcBest’s customers. The $0.9 million decrease in the loss in “Other and eliminations” in second quarter 2019, compared to second quarter 2018, was primarily due to lower expenses for certain incentive plans, partially offset by investments in technology. For the six months ended June 30, 2019, the $2.1 million increase in the loss reported in “Other and eliminations,” compared to the same period of 2018, was primarily due to investments in technology partially offset by lower expenses for certain incentive plans. As a result of our ongoing investments in technology, including the design and development of digital business platforms, and the seasonal impact of shared service allocations of other corporate costs, we expect the loss reported in “Other and eliminations” for third quarter 2019 to approximate $5.0 million and to be approximately $25.0 million for full year 2019.

In addition to the above items, consolidated net income and earnings per share were impacted by nonunion defined benefit pension expense, including settlement charges, and income from changes in the cash surrender value of variable life insurance policies, both of which are reported below the operating income line in the consolidated statements of operations. A portion of our variable life insurance policies have investments, through separate accounts, in equity and fixed income securities and, therefore, are subject to market volatility. Changes in the cash surrender value of life insurance policies contributed $0.02 and $0.08 to diluted earnings per share for the three- and six-month periods ended June 30, 2019, respectively, and contributed $0.03 and $0.04 per diluted per share, for the same respective prior-year periods.

32

Consolidated after-tax pension expense, including settlement charges, recognized for the nonunion defined benefit pension plan totaled $0.4 million, or $0.01 per diluted share, and $1.7 million, or $0.06 per diluted share, for the three and six months ended June 30, 2019, respectively, compared to $1.3 million, or $0.05 per diluted share, and $2.8 million, or $0.11 per diluted share, for the three and six months ended June 30, 2018, respectively. Pension settlement charges related to the plan termination, including those related to an annuity contract purchase, are expected to occur in 2019. In November 2017, an amendment was executed to terminate our nonunion defined benefit pension plan with a termination date of December 31, 2017. The plan began distributing immediate lump sum benefit payments related to the plan termination in fourth quarter 2018 and continued making these distributions during 2019. The plan received an extension from the Pension Benefit Guaranty Corporation (the “PBGC”) to allow additional time for the plan to administer the settlement of the remaining obligation for deferred benefits through the purchase of a nonparticipating annuity contract from an insurance company. In August 2019, the nonunion defined benefit pension plan received a preliminary bid for a nonparticipating annuity contract from an insurance company. Based on the most recently available actuarial information, including the preliminary bid received in August, nonunion pension settlement expense for the second half of 2019 is estimated to be approximately $2.0 million, or $1.5 million after-tax, and we estimate making a cash contribution to the plan of approximately $7.0 million, which would be deductible for income tax purposes, to fund an annuity contract purchase and the remaining benefit distributions expected to be made from the plan in excess of plan assets. However, there can be no assurances in regards to the required cash funding or pension settlement charges, as the actual amounts are dependent on various factors and will be determined using updated actuarial data.

For the six months ended June 30, 2018, consolidated net income and earnings per share were impacted by provisional tax benefits of $2.7 million, or $0.10 per diluted share, as a result of recognizing a reasonable estimate of the tax effects of the Tax Cuts and Jobs Act (the “Tax Reform Act”). Consolidated net income and earnings per share for the six months ended June 30, 2018 were also impacted by a tax credit of $1.2 million, or $0.05 per diluted share, for the February 2018 retroactive reinstatement of the alternative fuel tax credit related to the year ended December 31, 2017. The tax benefits and credits, including the impact of the Tax Reform Act, as well as other changes in the effective tax rates which impacted consolidated net income and earnings per share for the three and six months ended June 30, 2019 and 2018, are further described within the Income Taxes section of MD&A.

Consolidated Adjusted Earnings Before Interest, Taxes, Depreciation, and Amortization (“Adjusted EBITDA”)

We report our financial results in accordance with generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP performance measures and ratios, such as Adjusted EBITDA, utilized for internal analysis provide analysts, investors, and others the same information that we use internally for purposes of assessing our core operating performance and provides meaningful comparisons between current and prior period results, as well as important information regarding performance trends. Accordingly, using these measures improves comparability in analyzing our performance because it removes the impact of items from operating results that, in management's opinion, do not reflect our core operating performance. Management uses Adjusted EBITDA as a key measure of performance and for business planning. The measure is particularly meaningful for analysis of our operating performance, because it excludes amortization of acquired intangibles and software of our Asset-Light businesses, which are significant expenses resulting from strategic decisions rather than core daily operations. Additionally, Adjusted EBITDA is a primary component of the financial covenants contained in our Second Amended and Restated Credit Agreement (see Note F to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q). Other companies may calculate Adjusted EBITDA differently; therefore, our calculation of Adjusted EBITDA may not be comparable to similarly titled measures of other companies. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our reported results. Adjusted EBITDA should not be construed as a better measurement than operating income, operating cash flow, net income, or earnings per share, as determined under GAAP.

Asset-Based Operations

Asset-Based Segment Overview

The Asset-Based segment consists of ABF Freight System, Inc., a wholly-owned subsidiary of ArcBest Corporation, and certain other subsidiaries (“ABF Freight”). Our Asset-Based operations are affected by general economic conditions, as well as a number of other competitive factors that are more fully described in Item 1 (Business) and in Item 1A (Risk Factors) of Part I of our 2018 Annual Report on Form 10-K.

The key indicators necessary to understand the operating results of our Asset-Based segment, which are more fully described in the Asset-Based Segment Overview within the Asset-Based Operations section of Results of Operations in Item 7 (MD&A) of Part II of our 2018 Annual Report on Form 10-K, include:

● overall customer demand for Asset-Based transportation services, including the impact of economic factors;

● volume of transportation services provided, primarily measured by average daily shipment weight (“tonnage”), which influences operating leverage as the level of tonnage and number of shipments vary;

● prices obtained for services, primarily measured by yield (“revenue per hundredweight”), including fuel surcharges; and

● ability to manage cost structure, primarily in the area of salaries, wages, and benefits (“labor”), with the total cost structure measured by the percent of operating expenses to revenue levels (“operating ratio”).

34

As of June 2019, approximately 82% of our Asset-Based segment’s employees were covered under the ABF National Master Freight Agreement (the “2018 ABF NMFA”), the collective bargaining agreement with the International Brotherhood of Teamsters (the “IBT”), which will remain in effect through June 30, 2023. Under the 2018 ABF NMFA, the contractual wage and benefits costs, including the ratification bonuses and vacation restoration, are estimated to increase approximately 2.0% on a compounded annual basis through the end of the agreement, although the phase-in of an additional week of vacation results in a higher annual percentage increase in the earlier months of the agreement through the fourth quarter of 2019. The contractual wage rate under the 2018 ABF NMFA increased 1.4% effective July 1, 2019, and the average health, welfare, and pension benefit contribution rate is expected to increase approximately 2.2% effective primarily on August 1, 2019. Profit-sharing bonuses based on the Asset-Based segment’s annual operating ratios for any full calendar year under the contract would represent an additional increase in costs under the 2018 ABF NMFA.

As more fully described in the Asset-Based Operations section of Results of Operations within MD&A in Item 7 of the Company’s 2018 Annual Report on Form 10-K, ABF Freight’s multiemployer pension plan obligation with the New England Teamsters and Trucking Industry Pension Fund (the “New England Pension Fund”) was restructured under a transition agreement effective on August 1, 2018. The transition agreement resulted in ABF Freight’s withdrawal as a participating employer in the New England Pension Fund and triggered settlement of the related withdrawal liability. ABF Freight simultaneously re-entered the New England Pension Fund as a new participating employer free from any preexisting withdrawal liability and at a lower future contribution rate. ABF Freight recognized a one-time charge of $37.9 million (pre-tax) to record the withdrawal liability as of June 30, 2018, when the transition agreement was determined to be probable. In accordance with the transition agreement, ABF Freight made an initial lump sum cash payment of $15.1 million in third quarter 2018 and the remainder of the withdrawal liability, which had an initial aggregate present value of $22.8 million, will be settled with monthly payments to the New England Pension Fund over a period of 23 years. In accordance with current tax law, these payments are deductible for income taxes when paid.

(1) Revenue for undelivered freight is deferred for financial statement purposes in accordance with the revenue recognition policy. Billed revenue used for calculating revenue per hundredweight measurements has not been adjusted for the portion of revenue deferred for financial statement purposes.

(2) Dock, street, and yard (“DSY”) measures are further discussed in Asset-Based Operating Expenses within this section of Asset-Based Segment Results. The Asset-Based segment uses shipments per DSY hour to measure labor efficiency in its local operations, although total pounds per DSY hour is also a relevant measure when the average shipment size is changing.

(3) Total pounds per mile is used to measure labor efficiency of linehaul operations, although this metric is influenced by other factors including freight density, loading efficiency, average length of haul, and the degree to which purchased transportation (including rail service) is used.

Asset-Based Revenues

Asset-Based segment revenues for the three and six months ended June 30, 2019 totaled $559.6 million and $1,065.7 million, respectively, compared to $559.2 million and $1,041.4 million, respectively, for the same periods of 2018. Billed revenue (as described in footnote (1) to the key operating statistics table) increased 0.5% and 2.4% on a per-day basis for the three and six months ended June 30, 2019, respectively, compared to the same prior-year periods. The increases in total billed revenue reflect a 4.1% and 5.9% increase in total billed revenue per hundredweight, including fuel surcharges, for the three and six months ended June 30, 2019, respectively, partially offset by a 3.4% and 3.3% decrease in tonnage per day, respectively, compared to the same periods of 2018. The number of workdays was fewer by one half of a day in second quarter 2019 and by one day in the six months ended June 30, 2019, versus the same periods in 2018.

The increase in total billed revenue per hundredweight during the three- and six-month periods ended June 30, 2019, compared to the same periods of 2018, reflects yield improvement initiatives, including general rate increases, contract renewals, and further implementation of space-based pricing, partially offset by the impact of a higher proportion of truckload-rated spot business. We have continued to implement our space-based pricing program, which we introduced in third quarter 2017, by applying cubic minimum charges (“CMC”) on shipments subject to LTL tariffs to better reflect freight shipping trends that have evolved in recent years, as more fully described in the Asset-Based Segment Overview within the Asset-Based Operations section of Results of Operations in Item 7 (MD&A) of Part II of our 2018 Annual Report on Form 10-K. The Asset-Based segment implemented nominal general rate increases on its LTL base rate tariffs of 5.9% effective February 4, 2019 and April 16, 2018, although the rate changes vary by lane and shipment characteristics. Approximately one third of our Asset-Based business is subject to base LTL tariffs, which are affected by general rate increases, combined with individually negotiated discounts. Rates on the other two thirds of our Asset-Based business, including business priced in the spot market, are subject to individual pricing arrangements that are negotiated at various times throughout the year. Prices on accounts subject to deferred pricing agreements and annually negotiated contracts which were renewed during the three and six months ended June 30, 2019 increased approximately 3.1% and 3.6%, respectively, compared to the same periods of 2018. Excluding changes in fuel surcharges, average pricing on the Asset-Based segment’s LTL-rated business during the three and six months ended June 30, 2019 had high-single-digit percentage increases, compared to the same periods of 2018. Throughout the first six months of 2019, the fuel surcharge mechanism generally continued to have market acceptance among customers; however, certain nonstandard pricing

36

arrangements have limited the amount of fuel surcharge recovered. Our standard fuel surcharge program impacts approximately 35% of Asset-Based shipments and primarily affects noncontractual customers. There can be no assurances that the current pricing trend will continue. The competitive environment could limit the Asset-Based segment from securing adequate increases in base LTL freight rates and could limit the amount of fuel surcharge revenue recovered.

The 3.4% decrease in tonnage per day for the three months ended June 30, 2019, compared to the same period of 2018, reflects a mid-single digit percentage decrease in LTL-rated tonnage, partially offset by low-single digit percentage growth in truckload-rated freight. Total shipments per day decreased 1.2% and average weight per shipment declined 2.2% for the three-month period ended June 30, 2019, compared to the same period of 2018. The 3.3% decrease in tonnage per day for the six months ended June 30, 2019, compared to the same period of 2018, reflects lower LTL-rated and truckload-rated tonnage levels. Shipments per day increased 0.9% while average weight per shipment declined 4.1% for the six-month period ended June 30, 2019, compared to the same period of 2018. The lower weight per shipment for the three and six months ended June 30, 2019, compared to the same periods of 2018, reflects the effect of softer economic conditions on shipment size combined with increased capacity in the truckload market which offered more available capacity for customers to utilize truckload carriers for some of their large-sized shipments. In a reversal of the trend our Asset-Based segment has experienced in recent quarters, LTL-rated shipment levels declined in second quarter 2019, while truckload-rated shipment levels increased due to adding more volume-quoted spot shipments to improve the efficiency of our linehaul network.

Asset-Based Revenues — July 2019

Asset-Based billed revenues for the month of July 2019 decreased approximately 1.5% compared to July 2018 on a per-day basis. Total tonnage decreased approximately 2.0% per day, reflecting a higher mix of truckload-rated business. In July 2019, truckload-rated tonnage increased by a double-digit percentage, while LTL-rated tonnage decreased by a high-single-digit percentage, compared to the same prior-year period. Total shipments per day decreased approximately 3% in July 2019, compared to July 2018. Total weight per shipment increased approximately 1.0% in July 2019, with the weight per shipment on LTL-rated shipments down approximately 5%, versus the same prior-year period, reflecting changes in account mix. Total billed revenue per hundredweight for July 2019 increased approximately 0.5% compared to the July 2018 measure. High-single-digit percentage increases in revenue per hundredweight, excluding fuel surcharge, for the Asset-Based segment’s LTL-rated business were offset by lower yield on truckload-rated spot shipments moving in the Asset-Based network due to more available truckload market capacity in 2019.

Asset-Based Operating Income

The Asset-Based segment generated operating income of $36.2 million and $49.8 million for the three and six months ended June 30, 2019, respectively, compared to $3.4 million and $16.8 million, respectively, for the same periods of 2018. The Asset-Based segment operating ratio improved by 5.9 and 3.1 percentage points for the three and six months ended June 30, 2019, respectively, over the same prior-year periods. The 2018 periods include the $37.9 million one-time charge recognized in second quarter 2018 for the multiemployer plan withdrawal liability resulting from the transition agreement ABF Freight entered into with the New England Pension fund, as previously discussed in the Asset-Based Segment Overview. Excluding the one-time charge, the Asset-Based operating ratio increased by 0.9 and 0.5 percentage points for the three and six months ended June 30, 2019, respectively, versus the comparable 2018 periods, as revenue growth from continued strength in account pricing was more than offset by higher operating costs, including investments in technology to create a best-in-class customer experience. Costs related to these technology investments increased Asset-Based operating expenses by approximately $1.0 million and approximately $2.0 million for the three and six months ended June 30, 2019, respectively. We continue to make investments in technology, equipment, facilities, and other areas to address our customers’ evolving needs, and we anticipate the cost of these investments to total approximately $8.0 million for the Asset-Based segment in 2019. For the six-month period ended June 30, 2019, operating income was negatively impacted by approximately $2.0 million due to weather events in first quarter 2019 that reduced business levels and unfavorably impacted labor. The segment’s operating ratio was also impacted by changes in operating expenses as discussed in the following paragraphs.

37

Asset-Based Operating Expenses

Labor costs, which are reported in operating expenses as salaries, wages, and benefits, amounted to 53.1% and 54.2% of Asset-Based segment revenues for the three- and six-month periods ended June 30, 2019, compared to 51.3% and 53.5% for the same periods of 2018, primarily reflecting year-over-year increases in contractual wage and benefit contribution rates under the 2018 ABF NMFA. The contractual wage rate under the 2018 ABF NMFA increased 1.2% effective July 1, 2018, and the average health, welfare, and pension benefit contribution rate increased approximately 1.3% effective primarily on August 1, 2018. Expenses related to the restoration of one week of vacation under the 2018 ABF NMFA also increased salaries, wages, and benefits costs by $2.2 million and $4.1 million for the three and six months ended June 30, 2019, respectively, compared to the same periods of 2018. The additional week of vacation under the new labor agreement is accrued as it is earned for anniversary dates that begin on or after April 1, 2018. Salaries, wages, and benefits costs for the three and six months ended June 30, 2019, compared to the same period of 2018, were also impacted by an increase in workers’ compensation expense of $1.8 million and $1.5 million, respectively, primarily due to an increase in severity of claims experience. The segment’s higher labor costs were partially offset by lower expenses for certain nonunion performance-based incentive plans, including long-term incentive plans impacted by shareholder returns relative to peers.

Although the Asset-Based segment manages costs with shipment levels, portions of salaries, wages, and benefits are fixed in nature and the adjustments which would otherwise be necessary to align the labor cost structure throughout the system to corresponding tonnage levels are limited as the segment strives to maintain customer service. In the midst of a tight labor market, the Asset-Based segment retained freight handling personnel and drivers in the first half of 2019 to maintain customer service levels, despite lower tonnage levels compared to the same prior-year period. These resources allowed for lower utilization of local delivery agents and linehaul purchased transportation as further described in the following paragraph. Although certain productivity measures were negatively impacted by these strategic decisions, management believes the service emphasis provides opportunity to generate improved yields and business levels. Dock and street productivity metrics for the six-month period ended June 30, 2019 also reflect the negative impact of first quarter severe winter weather events previously described, compared to the same period of 2018. As a result, shipments per DSY hour declined 1.8% and 1.4% for the three and six months ended June 30, 2019, compared to the same prior-year periods. Productivity was negatively impacted by shipment profile metrics that increased handling costs for LTL shipments. The lower weight per shipment was a contributing profile factor of the 4.1% and 5.6% decline in pounds per DSY hour for the three and six months ended June 30, 2019, respectively, compared to the same periods of 2018. Pounds per mile declined 1.7% and 2.7% for the three and six months ended June 30, 2019, respectively, compared to the same periods of 2018, reflecting freight profile effects, including lower weight per shipment and shorter length of haul on available freight, while also maintaining service delivery schedules.

Rents and purchased transportation as a percentage of revenue decreased 1.0 and 0.4 percentage points for the three and six months ended June 30, 2019, compared to the same periods of 2018, primarily due to lower utilization of local delivery agents and linehaul purchased transportation as the Asset-Based segment focused on optimizing utilization of owned assets and retained additional labor resources to maintain customer service. The decrease in purchased transportation costs for second quarter 2019 were also impacted by lower rail utilization, as rail miles decreased approximately 6% compared to second quarter 2018. Rail miles were relatively consistent for the six months ended June 30, 2019, compared to the same period of 2018.

Shared services as a percentage of revenue decreased 0.2 percentage points for the three months ended June 30, 2019, compared to the same prior-year period, primarily due to lower expenses for certain nonunion performance-based incentive plans, including long-term incentive plans impacted by shareholder returns relative to peers. For the six months ended June 30, 2019, shared services increased 0.2 percentage points primarily due to higher costs related to enhancing the customer experience and initiatives for more streamlined delivery of customer relationship services which reflect investments in digital advertising, technologies, and personnel, partially offset by lower expenses related to certain nonunion performance-based incentive plans.

Gain on sale of property and equipment improved the Asset-Based segment’s operating ratio by 0.3 and 0.2 percentage points for the three and six months ended June 30, 2019, compared to the same periods of 2018, due to a $1.7 million gain recognized in second quarter 2019 on the sale of certain real estate previously used by our service center operations.

Asset-Light Operations

Asset-Light Overview

The ArcBest and FleetNet reportable segments, combined, represent our Asset-Light operations. Our Asset-Light operations are a key component of our strategy to offer customers a single source of end-to-end logistics solutions, designed to satisfy the complex supply chain and unique shipping requirements customers encounter. We have unified our sales, pricing, customer service, marketing, and capacity sourcing functions to better serve our customers through delivery of integrated logistics solutions.

Our Asset-Light operations are affected by general economic conditions, as well as a number of other competitive factors that are more fully described in Item 1 (Business) and in Item 1A (Risk Factors) of Part I of our 2018 Annual Report on Form 10-K. The key indicators necessary to understand our Asset-Light operating results include:

● customer demand for logistics and premium transportation services combined with economic factors which influence the number of shipments or service events used to measure changes in business levels;

● prices obtained for services, primarily measured by revenue per shipment or event;

● availability of market capacity and cost of purchased transportation to fulfill customer shipments; and

● management of operating costs.

Asset-Light Results

For the three and six months ended June 30, 2019, the combined revenues of our Asset-Light operations totaled $232.9 million and $459.4 million, respectively, compared to $246.8 million and $476.5 million, respectively, for the same periods of 2018. The combined revenues of our Asset-Light operating segments generated approximately 29% and 30% of our total revenues before other revenues and intercompany eliminations for the three and six months ended June 30, 2019, respectively, compared to 31% for both the three and six months ended June 30, 2018.

ArcBest Segment

The following table sets forth a summary of operating expenses and operating income as a percentage of revenue for the ArcBest segment:

	Three Months Ended				Six Months Ended
	June 30				June 30
	2019		2018		2019		2018
ArcBest Segment Operating Expenses (Operating Ratio)
Purchased transportation	81.4	%	81.5	%	81.2	%	81.5	%
Supplies and expenses	1.6		1.7		1.6		1.8
Depreciation and amortization	1.7		1.8		1.7		1.8
Shared services	12.8		11.7		13.0		11.9
Other	1.3		1.3		1.4		1.2
Restructuring costs	—		0.1		—		—
	98.8	%	98.1	%	98.9	%	98.2	%
ArcBest Segment Operating Income	1.2	%	1.9	%	1.1	%	1.8	%

A comparison of key operating statistics for the ArcBest segment presented in the following table reflects the segment’s combined operations, excluding statistical data related to managed transportation solutions transactions. Growth in managed transportation solutions has increased the number of shipments for these services to approximately one-third of the ArcBest segment’s total shipments, while the business represents less than 10% of segment revenues for the three and six months ended June 30, 2019. Due to the nature of our managed transportation solutions which typically involve a larger number of shipments at a significantly lower revenue per shipment level than the segment’s other service offerings, inclusion of the managed transportation solutions data would result in key operating statistics which are not representative of the operating results of the segment as a whole. As such, the key operating statistics management uses to evaluate performance of the ArcBest segment exclude managed transportation solutions transactions.

	Year Over Year % Change
	Three Months Ended		Six Months Ended
	June 30, 2019		June 30, 2019
Revenue / Shipment		(9.8%)		(8.3%)
Shipments / Day		(1.6%)		(1.3%)

ArcBest segment revenues totaled $181.2 million and $354.4 million for the three and six months ended June 30, 2019, respectively, compared to $200.0 million and $381.9 million, respectively, for the same periods of 2018. The 9.4% and 7.2% decrease in revenues for the three and six months ended June 30, 2019, respectively, compared to the same prior-year periods, primarily reflects decreases in revenue per shipment associated with lower market prices and fewer shipments on a per-day basis resulting from increased available truckload market capacity in the three and six months ended June 30, 2019, compared to the tighter capacity experienced in the same periods of 2018. More truckload market capacity in 2019 was the primary driver of reduced market pricing for expedite and truckload brokerage services compared to the strong market for these services in 2018. The revenue declines for our expedite and truckload brokerage services were partially offset by higher demand for managed transportation solutions and the impact of increased tariffs on the segment’s international services for three and six months ended June 30, 2019, compared to the same periods of 2018.

Operating income decreased $1.6 million and $3.0 million for the three and six months ended June 30, 2019, respectively, compared to the same periods of 2018, primarily reflecting the declines in revenue. Purchased transportation costs decreased 0.1 and 0.3 percentage points as a percentage of revenue for the three and six months ended June 30, 2019, respectively, compared to the same periods of 2018, primarily due to reduced purchased transportation rates attributable to more available truckload capacity and beneficial growth in our owner-operator fleet. Although the ArcBest segment manages costs with shipment levels, portions of operating costs are fixed in nature and the adjustments which would otherwise be necessary to align the cost structure to corresponding revenue and shipment levels are limited as the segment strives to maintain customer service. Shared services expenses increased 1.1 percentage points as a percentage of revenue in the three and six months ended June 30, 2019, respectively, compared to the same prior-year periods, primarily due to strategic development of our owner-operator fleet and contract carrier capacity in addition to the effect of intersegment cost allocations that are based on shipment or activity levels which declined less than the reduction in revenue per shipment. Elevated costs associated with long-term investment in our owner-operator fleet and contract carrier capacity will continue for the remainder of the year and we expect these investments to increase ArcBest segment expenses by approximately $0.5 million in both the third and fourth quarters of 2019, compared to the same periods of 2018.  

ArcBest Segment Revenues – July 2019

Revenues of our ArcBest segment (ArcBest Asset-Light operations, excluding FleetNet) decreased approximately 4.5% on a per-day basis in July 2019, compared to July 2018, and purchased transportation expense was approximately flat between the periods. Available truckload capacity during 2019, compared to the tight capacity environment in 2018, led to lower revenue per shipment and reduced demand for expedite services in July 2019 versus July 2018. Managed transportation solutions continued to have a positive impact on the ArcBest segment’s business in July 2019.

FleetNet Segment

FleetNet’s revenues totaled $51.7 million and $105.0 million for the three and six months ended June 30, 2019, compared to $46.8 million and $94.6 million, respectively, for the same periods of 2018. The 10.5% and 11.0% increase in revenues for the three and six months ended June 30, 2019, respectively, compared to the same periods of 2018, was driven by higher service event volume, primarily due to an increase in preventative maintenance service events provided to our Asset-Based segment.

FleetNet’s operating income totaled $1.0 million for each of the three-month periods ended June 30, 2019 and 2018, and totaled $2.5 million and $2.6 million for the six-month periods ended June 30, 2019 and 2018, respectively. FleetNet’s operating income margins for the three and six months ended June 30, 2019, compared to the same periods of 2018, were impacted by lower revenue per event on maintenance services combined with increased operating costs to service the event growth.

Asset-Light Adjusted Earnings Before Interest, Taxes, Depreciation, and Amortization (“Adjusted EBITDA”)

We report our financial results in accordance with GAAP. However, management believes that certain non-GAAP performance measures and ratios, such as Adjusted EBITDA, utilized for internal analysis provide analysts, investors, and others the same information that we use internally for purposes of assessing our core operating performance and provides meaningful comparisons between current and prior period results, as well as important information regarding performance trends. The use of certain non-GAAP measures improves comparability in analyzing our performance because it removes the impact of items from operating results that, in management's opinion, do not reflect our core operating performance. Management uses Adjusted EBITDA as a key measure of performance and for business planning. The measure is particularly meaningful for analysis of our Asset-Light businesses, because it excludes amortization of acquired intangibles and software, which are significant expenses resulting from strategic decisions rather than core daily operations. Management also believes Adjusted EBITDA to be relevant and useful information, as EBITDA is a standard measure commonly reported and widely used by analysts, investors, and others to measure financial performance of asset-light businesses and the ability to service debt obligations. Other companies may calculate Adjusted EBITDA differently; therefore, our calculation of Adjusted EBITDA may not be comparable to similarly titled measures of other companies. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our reported results. Adjusted EBITDA should not be construed as a better measurement than operating income, operating cash flow, net income, or earnings per share, as determined under GAAP.

(1) The calculation of Adjusted EBITDA as presented in this table begins with operating income, as other income (costs), income taxes, and net income are reported at the consolidated level and not included in the operating segment financial information evaluated by management to make operating decisions. Consolidated Adjusted EBITDA is reconciled to consolidated net income in the Consolidated Results section of Results of Operations.

(2) For the ArcBest segment, includes amortization of acquired intangibles of $1.1 million and $2.2 million for the three and six months ended June 30, 2019, respectively, compared to $1.2 million and $2.3 million, respectively, for the same prior-year periods.

(3) Restructuring costs relate to the realignment of our corporate structure.

Environmental and Legal Matters

We are subject to federal, state, and local environmental laws and regulations relating to, among other things: emissions control, transportation or handling of hazardous materials, underground and aboveground storage tanks, stormwater pollution prevention, contingency planning for spills of petroleum products, and disposal of waste oil. We may transport or arrange for the transportation of hazardous materials and explosives, and we operate in industrial areas where truck service centers and other industrial activities are located and where groundwater or other forms of environmental contamination could occur. See Note L to our consolidated financial statements included in Part I, Item 1 of this Quarterly

41

Report on Form 10-Q for further discussion of the environmental matters to which we are subject and the reserves we currently have recorded in our consolidated financial statements for amounts related to such matters.

We are involved in various legal actions, the majority of which arise in the ordinary course of business. We maintain liability insurance against certain risks arising out of the normal course of our business, subject to certain self-insured retention limits. We routinely establish and review the adequacy of reserves for estimated legal, environmental, and self-insurance exposures. While management believes that amounts accrued in the consolidated financial statements are adequate, estimates of these liabilities may change as circumstances develop. Considering amounts recorded, routine legal matters are not expected to have a material adverse effect on our financial condition, results of operations, or cash flows.

Information Technology and Cybersecurity

We depend on the proper functioning, availability, and security of our information systems, including communications, data processing, financial, and operating systems, as well as proprietary software programs, that are integral to the efficient operation of our business. Cybersecurity attacks and other cyber incidents that impact the availability, reliability, speed, accuracy, or other proper functioning of these systems or that result in proprietary information or sensitive or confidential data being compromised could have a significant impact on our operations. Any new or enhanced technology that we may develop and implement may also be subject to cybersecurity attacks and may be more prone to related incidents. We also utilize certain software applications provided by third parties and provide underlying data which is utilized by third parties who provide certain outsourced administrative functions, either of which may increase the risk of a cybersecurity incident. Although we strive to carefully select our third-party vendors, we do not control their actions and any problems caused by these third parties, including cyber attacks and security breaches at a vendor, could adversely affect our ability to provide service to our customers and otherwise conduct our business. Our information systems are protected through physical and software safeguards as well as backup systems considered appropriate by management. However, it is not practicable to protect against the possibility of power loss, telecommunications failures, cybersecurity attacks, and other cyber events in every potential circumstance that may arise. To mitigate the potential for such occurrences at our corporate headquarters, we have implemented various systems, including redundant telecommunication facilities; replication of critical data to an offsite location; a fire suppression system to protect our on-site data center; and electrical power protection and generation facilities. We also have a catastrophic disaster recovery plan and alternate processing capability available for our critical data processes in the event of a catastrophe that renders our corporate headquarters unusable.

Our business interruption and cyber insurance would offset losses up to certain coverage limits in the event of a catastrophe or certain cyber incidents; however, losses arising from a catastrophe or significant cyber incident would likely exceed our insurance coverage and could have a material adverse impact on our results of operations and financial condition. Furthermore, a significant disruption in our information technology systems or a significant cyber incident, including denial of service, system failure, security breach, intentional or inadvertent acts by employees or vendors with access to our systems or data, disruption by malware, or other damage, could interrupt or delay our operations, damage our reputation, cause a loss of customers, cause errors or delays in financial reporting, expose us to a risk of loss or litigation, and/or cause us to incur significant time and expense to remedy such an event. We have experienced incidents involving attempted denial of service attacks, malware attacks, and other events intended to disrupt information systems, wrongfully obtain valuable information, or cause other types of malicious events that could have resulted in harm to our business. To date, the systems employed have been effective in identifying these types of events at a point when the impact on our business could be minimized. We must continuously monitor and develop our information technology networks and infrastructure to prevent, detect, address, and mitigate the risk of unauthorized access, misuse, computer viruses, and other events that could have a security impact. We have made and continue to make significant financial investments in technologies and processes to mitigate these risks. We also provide employee awareness training around phishing, malware, and other cyber risks. Management is not aware of any cybersecurity incident that has had a material effect on our operations, although there can be no assurances that a cyber incident that could have a material impact to our operations could not occur.

Liquidity and Capital Resources

Our primary sources of liquidity are cash, cash equivalents, and short-term investments, cash generated by operations, and borrowing capacity under our revolving credit facility or accounts receivable securitization program.

Cash Flow and Short-Term Investments

Components of cash and cash equivalents and short-term investments were as follows:

	June 30		December 31
	2019		2018
	(in thousands)
Cash and cash equivalents(1)	$	181,731	$	190,186
Short-term investments(2)		117,657		106,806
Total(3)	$	299,388	$	296,992

(1) Cash equivalents consist of money market funds, variable rate demand notes, and, at December 31, 2018, U.S. Treasury securities.

(2) Short-term investments consist of certificates of deposit and U.S. Treasury securities.

(3) Cash, variable rate demand notes, and certificates of deposit are recorded at cost plus accrued interest, which approximates fair value. Money market funds are recorded at fair value based on quoted prices. U.S. Treasury securities are recorded at cost plus amortized premium or discount and accrued interest. At June 30, 2019 and December 31, 2018, cash, cash equivalents, and short-term investments totaling $68.9 million and $94.7 million, respectively, were neither FDIC insured nor direct obligations of the U.S. government.

Cash, cash equivalents, and short-term investments increased $2.4 million from December 31, 2018 to June 30, 2019. During the six-month period ended June 30, 2019, cash provided by operations was used to repay $20.4 million of long-term debt, net of proceeds; fund $38.1 million of capital expenditures (and an additional $11.0 million of certain Asset-Based revenue equipment was financed with notes payable), net of proceeds from asset sales; fund $5.5 million of internally developed software; purchase $5.2 million of treasury stock; and pay dividends of $4.1 million on common stock.

Cash provided by operating activities during the six months ended June 30, 2019 was $80.5 million, compared to cash provided by operating activities of $119.6 million in the same prior-year period. Net income for the three months ended June 30, 2018, was reduced by a $37.9 million (pre-tax), or $28.2 million (after-tax), one-time charge recognized in second quarter 2018 for the multiemployer plan withdrawal liability resulting from the transition agreement ABF Freight entered into with the New England Pension fund (previously discussed within the Asset-Based Segment Overview section of MD&A Results of Operations). Excluding the effect of establishing the multiemployer pension withdrawal liability, net income declined $10.1 million during the six months ended June 30, 2019 compared to the prior-year period. The $39.1 million decrease in cash provided by operating activities is primarily related to growth in working capital (which resulted in cash outflow), the lower income level and $5.3 million of adjustments to net income for noncash operating expenses and changes in income taxes for the six months ended June 30, 2019, compared to the same period of 2018.

Changes in working capital, which contributed to $24.2 million of the decrease in operating cash flow, were primarily due to decreases in accrued expenses, accounts payable, and other liabilities, partially offset by a decrease in accounts receivable, for the six months ended June 30, 2019, compared to increases in accounts payable, partially offset by an increase in accounts receivable, for the same period of 2018. For the six months ended June 30, 2019, accrued expenses, accounts payable, and other liabilities decreased primarily due to operating lease payments made during the six months ended June 30, 2019 and higher payouts in first quarter 2019 combined with lower accruals during the six months ended June 30, 2019 for certain nonunion performance-based incentive plans, partially offset by higher accruals related to purchased transportation and labor costs in our segment operations. The increase in accounts payable for the six months ended June 30, 2018 was primarily due to an increase in the accrual for equipment received and increases in accruals related to purchased transportation and other expenses in our segment operations related to higher business levels in June 2018 compared to December 31, 2017. Accounts receivable decreased as of June 30, 2019, compared to December 31,

43

2018, due to improved collection levels, and increased as of June 30, 2018, compared to December 31, 2017, primarily due to higher business levels in June 2018 versus December 2017.

Cash, cash equivalents, and short-term investments increased $50.1 million from December 31, 2017 to June 30, 2018. During the six-month period ended June 30, 2018, cash provided by operations of $119.6 million was used to repay $33.7 million of notes payable; fund $22.7 million of capital expenditures (and an additional $14.4 million of certain Asset-Based revenue equipment was financed with notes payable), net of proceeds from asset sales; and pay dividends of $4.1 million on common stock.

Financing Arrangements

Our financing arrangements are discussed in Note F to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Contractual Obligations

We have purchase obligations, consisting of authorizations to purchase and binding agreements with vendors, relating to revenue equipment used in our Asset-Based operations, other equipment, facility improvements, software, certain service contracts, and other items for which amounts were not accrued in the consolidated balance sheet as of June 30, 2019. These purchase obligations totaled $122.2 million as of June 30, 2019, with $109.0 million estimated to be paid within the next year, $10.9 million estimated to be paid in the following two-year period, and $2.3 million to be paid within five years, provided that vendors complete their commitments to us. Purchase obligations for revenue equipment and other equipment are included in our 2019 capital expenditure plan. We also have contractual obligations for operating leases, primarily related to our Asset-Based service centers, as of June 30, 2019 which are disclosed in Note E to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Our contractual obligations related to our notes payable, which provide financing for revenue equipment and software purchases, totaled $184.6 million, including interest, as of June 30, 2019, a decrease of $10.4 million from December 31, 2018. The scheduled maturities of our long-term debt obligations as of June 30, 2019 are disclosed in Note F to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q. There have been no other material changes in the contractual obligations disclosed in our 2018 Annual Report on Form 10-K during the six months ended June 30, 2019.

For 2019, our total capital expenditures, including amounts financed, are estimated to range from $170.0 million to $180.0 million, net of asset sales. These 2019 estimated net capital expenditures include revenue equipment purchases of $90.0 million, primarily for our Asset-Based operations. The remainder of 2019 expected capital expenditures includes real estate projects, costs of other facility and handling equipment for our Asset-Based operations, including forklifts, and technology investments across the enterprise. We have the flexibility to adjust certain planned 2019 capital expenditures as business levels dictate. Depreciation and amortization expense, excluding amortization of intangibles, is estimated to be in a range of $110.0 million to $115.0 million in 2019.

As previously disclosed within the Consolidated Results section of Results of Operations, our nonunion defined benefit pension plan was terminated with an effective date of December 31, 2017 and the liquidation of plan assets and settlement of plan obligations is expected to be completed in 2019. In August 2019, the plan received a preliminary bid for a nonparticipating annuity contract from an insurance company. Based on the most recently available actuarial information, including the preliminary bid, we estimate making a cash contribution to the plan to fund an annuity contract purchase and the remaining benefit distributions expected to be made from the plan in excess of plan assets of approximately $7.0 million, which would be deductible for income tax purposes, although there can be no assurances in this regard as the actual contribution amount is dependent on various factors and will be determined using updated actuarial data.

ABF Freight System, Inc. and certain other subsidiaries reported in our Asset-Based operating segment contribute to multiemployer health, welfare, and pension plans based generally on the time worked by their contractual employees, as specified in the collective bargaining agreement and other supporting supplemental agreements (see Note G to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q).

44

Other Liquidity Information

Cash, cash equivalents, and short-term investments totaled $299.4 million at June 30, 2019. General economic conditions, along with competitive market factors and the related impact on our business, primarily the tonnage and pricing levels that the Asset-Based segment receives for its services, could affect our ability to generate cash from operations and maintain cash, cash equivalents, and short-term investments on hand as operating costs increase. Our revolving credit facility (“Credit Facility”) under our Second Amended and Restated Credit Agreement (“Credit Agreement”) and our accounts receivable securitization program provide available sources of liquidity with flexible borrowing and payment options. We had available borrowing capacity under our Credit Facility and our accounts receivable securitization program of $130.0 million and $70.1 million, respectively, at June 30, 2019. We believe these agreements provide borrowing capacity options necessary for growth of our businesses. We believe existing cash, cash equivalents, short-term investments, cash generated by operations, and amounts available under our Credit Agreement or accounts receivable securitization program will be sufficient to meet our liquidity needs, including financing potential acquisitions and the repayment of amounts due under our financing arrangements, for the foreseeable future. Notes payable, finance leases, and other secured financing may also be used to fund capital expenditures, provided that such arrangements are available and the terms are acceptable to us.

During 2019, we are continuing to take actions to enhance shareholder value with our quarterly dividend payments and treasury stock purchases. On July 25, 2019, our Board of Directors declared a dividend of $0.08 per share to stockholders of record as of August 9, 2019. We expect to continue to pay quarterly dividends on our common stock in the foreseeable future, although there can be no assurances in this regard since future dividends will be at the discretion of the Board of Directors and are dependent upon our future earnings, capital requirements, and financial condition; contractual restrictions applying to the payment of dividends under our Credit Agreement; and other factors.

We have a program in place to repurchase our common stock in the open market or in privately negotiated transactions. The program has no expiration date but may be terminated at any time at the Board of Directors’ discretion. Repurchases may be made using cash reserves or other available sources. During the six months ended June 30, 2019, we purchased 168,535 shares of our common stock for an aggregate cost of $5.2 million, leaving $17.1 million available for repurchase under the current buyback program.

Our Credit Facility, accounts receivable securitization program, and interest rate swap agreements utilize interest rates based on LIBOR. LIBOR is the basic rate of interest used in lending between banks on the London interbank market and is widely used as a reference for setting the interest rates on loans globally. In July 2017, the United Kingdom’s Financial Conduct Authority (the “FCA”), which regulates LIBOR, announced that it intends to phase out LIBOR by the end of 2021. The Alternative Reference Rates Committee (the “ARRC”), a steering committee comprised of private-sector entities including large U.S. financial institutions, was jointly convened by the Federal Reserve Board and the Federal Reserve Bank of New York to help ensure a successful transition from LIBOR to an alternative reference rate in the United States. The ARRC selected the Secured Overnight Financing Rate (the “SOFR”) as its preferred replacement for LIBOR, and the Federal Reserve Bank of New York began publishing SOFR rates in April 2018. The SOFR is calculated by the Federal Reserve Board based on the interest rates banks charge one another in the overnight market, typically called repurchase agreements, and is intended to be a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities.

In October 2018, the FASB amended ASC Topic 815, Derivatives and Hedging, to permit the SOFR Overnight Index Swap (OIS) Rate as a U.S. benchmark interest rate. This amendment was effective for us on January 1, 2019 and it did not have an impact on our consolidated financial statements. We are currently reviewing contract language provided by our lenders which would allow for the use of an alternative to LIBOR in calculating the interest rate under our borrowing arrangements. Any such changes to the terms of our borrowing arrangements are anticipated to be effective in 2022 upon our agreement with the lenders as to the replacement reference rate. We anticipate amending such agreements, as appropriate, in the near future. It is our understanding that replacement of LIBOR with an alternative reference in determining the interest rate under our borrowing arrangements will not have a significant impact on our cost of borrowing; however, there can be no assurances in this regard, as the new rates resulting from the replacement of LIBOR in our borrowing arrangements may not be as favorable to us as those in effect prior to any LIBOR phase-out.

Financial Instruments

We have not historically entered into financial instruments for trading purposes, nor have we historically engaged in a program for fuel price hedging. No such instruments were outstanding as of June 30, 2019. We have interest rate swap agreements in place which are discussed in Note F to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Balance Sheet Changes

Operating Right-of-Use Assets

The $68.8 million increase in operating right-of-use assets from December 31, 2018 to June 30, 2019 is due to adoption of Accounting Standards Codification Topic 842, Leases, (“ASC Topic 842”) effective January 1, 2019, and represents the recognition of right-of-use assets from operating lease agreements in our consolidated balance sheet.

Accounts Payable

The $23.0 million increase in accounts payable from December 31, 2018 to June 30, 2019, is primarily due to a $16.6 million increase in the accrual for equipment received.  

Accrued Expenses

Accrued expenses decreased $14.1 million from December 31, 2018 to June 30, 2019, primarily due to payment during the first quarter 2019 of amounts accrued at December 31, 2018 for certain incentive accruals related to our improved operating performance and the current portion of long-term incentive plans, a portion of which are driven by shareholder returns relative to peers, and contributions to defined contribution plans. The impact of these payments on the decrease in accrued expenses was partially offset by accruals for the incentive plans during 2019, as well as an increase in vacation accruals for union employees related, in part, to the restoration of a week of vacation under the 2018 ABF NMFA, and an increase in the workers’ compensation expense accrual due to higher severity of claims experienced during 2019.

Current Portion of Operating Lease Liabilities and Operating Lease Liabilities

The $18.3 million and $54.0 million increases in current and long-term operating lease liabilities, respectively, from December 31, 2018 to June 30, 2019, are due to the January 1, 2019 adoption of ASC Topic 842 and represent the recognition of liabilities from operating lease agreements in our consolidated balance sheet.

Off-Balance Sheet Arrangements

At June 30, 2019, our off-balance sheet arrangements for purchase obligations totaled $122.2 million, as previously discussed in the Contractual Obligations section of Liquidity and Capital Resources.

We have no investments, loans, or any other known contractual arrangements with unconsolidated special-purpose entities, variable interest entities, or financial partnerships and have no outstanding loans with executive officers or directors.

Income Taxes

Our effective tax rate was 27.4% and 27.1% of pre-tax income for the three and six months ended June 30, 2019. Our effective tax benefit rate was 68.0% and 15.0% of pre-tax income for the three and six months ended June 30, 2018. As a result of the Tax Reform Act and our use of a fiscal year rather than a calendar year for U.S. income tax filing, taxes for the tax year ended February 28, 2018 were required to be calculated by applying a blended rate to taxable income. In computing total tax expense for the three and six months ended June 30, 2018, a 32.74% blended rate was applied to the two months ended February 28, 2018, and a 21.0% federal statutory rate was applied to the months of March 2018 through June 30, 2018. A federal statutory rate of 21.0% was applied to the three and six months ended June 30, 2019.  The average state tax rate, net of the associated federal deduction, is approximately 5%. However, various factors may cause the full-year 2019 tax rate to vary significantly from the statutory rate. Our full year 2019 tax rate is expected to be approximately 26% to 27%, while the effective rate in any quarter may be impacted by items discrete to that period.

46

At December 31, 2017, as a result of the Tax Reform Act, we remeasured deferred federal tax assets and liabilities based on the rate at which they were expected to reverse in the future. Existing deferred tax assets and liabilities at December 31, 2017 that were reasonably estimated to reverse in the tax year ending February 28, 2018 were remeasured at a rate of 32.74%. Existing deferred tax assets and liabilities at December 31, 2017 that were reasonably estimated to reverse after the tax year ending February 28, 2018 were remeasured at a rate of 21.0%. In the first six months of 2018, a provisional reduction of net deferred income tax liabilities was recognized related to the reversal of temporary differences through our tax year end of February 28, 2018. As a result, we recognized a provisional deferred tax benefit of $2.6 million for the six months ended June 30, 2018, which impacted the effective tax benefit rate as noted in the following table. As of December 31, 2018, the accounting for the income tax effects of the Tax Reform Act was complete and all amounts recorded were considered final.

Reconciliation between the effective income tax rate, as computed on income before income taxes, and the statutory federal income tax rate is presented in the following table:

	Three Months Ended								Six Months Ended
	June 30								June 30
	2019				2018				2019				2018
	(in thousands)

(1) For the three and six months ended June 30, 2018, the effect of the change in the U.S. corporate tax rate to 21% in accordance with the Tax Reform Act is reflected in separate components of the reconciliation.

(2) The six-month period ended June 30, 2018 was impacted by the February 2018 passage of the Bipartisan Budget Act of 2018 which retroactively reinstated the alternative fuel tax credit that had previously expired on December 31, 2016. The credit was reinstated through December 31, 2017 and the $1.2 million credit related to 2017 was recognized in the first quarter of 2018.

At June 30, 2019, we had $54.8 million of net deferred tax liabilities after valuation allowances. We evaluated the need for a valuation allowance for deferred tax assets at June 30, 2019 by considering the future reversal of existing taxable temporary differences, future taxable income, and available tax planning strategies. Valuation allowances for deferred tax assets totaled $0.1 million at June 30, 2019 and at December 31, 2018. As of June 30, 2019, deferred tax liabilities which will reverse in future years exceeded deferred tax assets.

In first quarter of 2019, we recorded a deferred tax asset of approximately $19.0 million related to our operating lease liabilities and recorded a deferred tax liability of approximately $19.0 million related to our operating lease right-of-use assets due to the adoption of ASC Topic 842.  

Financial reporting income may differ significantly from taxable income because of items such as revenue recognition, accelerated depreciation for tax purposes, pension accounting rules, and a significant number of liabilities such as vacation pay, workers’ compensation, and other liabilities, which, for tax purposes, are generally deductible only when paid. For the six months ended June 30, 2019, financial reporting income exceeded income determined under income tax law. For the six months ended June 30, 2018, income determined under income tax law exceeded financial reporting income.

47

During the six months ended June 30, 2019, we made federal, state, and foreign tax payments of $8.9 million, and received refunds of less than $0.1 million of state income taxes that were paid in prior years. Management does not expect the cash outlays for income taxes will materially exceed reported income tax expense for the foreseeable future.

Critical Accounting Policies

The accounting policies that are “critical,” or the most important, to understand our financial condition and results of operations and that require management to make the most difficult judgments are described in our 2018 Annual Report on Form 10-K. There have been no material changes in the Company’s critical accounting policies during the six months ended June 30, 2019.

Accounting Pronouncements Not Yet Adopted

New accounting rules and disclosure requirements can significantly impact our reported results and the comparability of financial statements. Accounting pronouncements which have been issued but are not yet effective for our financial statements are disclosed in Note A to our consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q. Management believes that there is no new accounting guidance issued but not yet effective that will impact our critical accounting policies.

ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION

ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION

NOTE A – ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION

ArcBest Corporation^TM (the “Company”) is the parent holding company of businesses providing integrated logistics solutions. The Company’s operations are conducted through its three reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries; ArcBest^®, the Company’s asset-light logistics operation; and FleetNet^®. References to the Company in this Quarterly Report on Form 10-Q are primarily to the Company and its subsidiaries on a consolidated basis.

The Asset-Based segment represented approximately 71% of the Company’s total revenues before other revenues and intercompany eliminations for the six months ended June 30, 2019. As of June 2019, approximately 82% of the Asset-Based segment’s employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “2018 ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which will remain in effect through June 30, 2023.

Financial Statement Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) pertaining to interim financial information. Accordingly, these interim financial statements do not include all information or footnote disclosures required by accounting principles generally accepted in the United States for complete financial statements and, therefore, should be read in conjunction with the audited financial statements and accompanying notes included in the Company’s 2018 Annual Report on Form 10-K and other current filings with the SEC. In the opinion of management, all adjustments (which are of a normal and recurring nature) considered necessary for a fair presentation have been included.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts may differ from those estimates.

Accounting Policies

The Company’s accounting policies are described in Note B to the consolidated financial statements included in Part II, Item 8 of the Company’s 2018 Annual Report on Form 10-K. The following policies have been updated during the six months ended June 30, 2019 for the adoption of accounting standard updates disclosed within this Note.

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 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. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions.

Leases: The Company leases, under finance and operating lease arrangements, certain facilities used primarily in the Asset-Based segment service center operations, certain revenue equipment used in the ArcBest segment operations, and certain other office equipment. The Company adopted Accounting Standards Codification (“ASC”) Topic 842, Leases, (“ASC Topic 842”) effective January 1, 2019. In accordance with ASC Topic 842, right-of-use assets and lease liabilities for operating leases are recorded on the balance sheet and the related lease expense is recorded on a straight-line basis over

the lease term in operating expenses. Included in lease expense are any variable lease payments incurred in the period that were not included in the initial lease liability. For financial reporting purposes, right-of-use assets held under finance leases are amortized over their estimated useful lives on the same basis as owned assets, and leasehold improvements associated with assets utilized under finance 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 finance leases is included in depreciation expense. Obligations under the finance lease arrangements are included in long-term debt.

The short-term lease exemption was elected under ASC Topic 842 for all classes of assets to include real property, revenue equipment, and service, office, and other equipment. The Company adopted the policy election as a lessee for all classes of assets to account for each lease component and its related non-lease component(s) as a single lease component. In determining the discount rate, the Company uses the rate implicit in the lease if that rate is readily determinable when entering into a lease as a lessee. If the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate, determined by the price of a fully collateralized loan with similar terms based on current market rates.

For contracts entered into on or after the effective date, an assessment is made as to whether the contract is, or contains, a lease at the inception of a contract. The assessment is based on: (1) whether the contract involves the use of a distinct identified asset; (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period; and (3) whether the Company has the right to direct the use of the asset. For all operating leases that meet the scope of ASC Topic 842, a right-of-use asset and a lease liability are recognized. The right-of-use asset is measured as the initial amount of the lease liability, plus any initial direct costs incurred, less any prepayments prior to commencement or lease incentives received. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s secured incremental borrowing rate for the same term as the underlying lease. Lease payments included in the measurement of the lease liability are comprised of the following: (1) the fixed noncancelable lease payments, (2) payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and (3) payments for early termination options unless it is reasonably certain the lease will not be terminated early. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement and included in the measurement of the initial lease liability. Additional payments based on the change in an index or rate are recorded as a period expense when incurred. Lease modifications result in remeasurement of the lease liability.

Adopted Accounting Pronouncements

ASC Topic 842, which was adopted by the Company effective 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. The Company elected the modified retrospective method of applying the transition provisions at the beginning of the period of adoption and, as a result, has not adjusted comparative period financial information and has not included the new lease disclosures for periods before the effective date. Prior period amounts continue to be reported under the Company’s historical accounting in accordance with the previous lease guidance included in ASC Topic 840.

The Company has excluded short-term leases from accounting under ASC Topic 842 and has elected the package of practical expedients as permitted under the transition guidance, which allowed the Company to not reassess: (1) whether contracts are, or contain, leases; (2) lease classification; and (3) capitalization of initial direct costs. For contracts entered into on or after the effective date, an assessment is made as to whether the contract is, or contains, a lease at the inception of a contract. Consistent with the package of practical expedients elected, leases entered into prior to January 1, 2019, are accounted for under ASC Topic 840 and were not reassessed. For all classes of assets, the policy election was made to account for each lease component and its related non-lease component(s) as a single lease component. The election to not recognize right-of-use assets and lease liabilities for short-term leases that have a term of 12 months or less did not have a material effect on the right-of-use assets and lease liabilities.

The majority of the Company’s lease portfolio consists of real property operating leases related to facilities used in the Asset-Based segment service center operations. The lease portfolio also includes operating leases related to certain revenue equipment used in the ArcBest segment operations as well as a small number of office equipment finance leases. Management has recorded the right-of-use assets and associated lease liabilities for operating leases on the consolidated

balance sheet as of June 30, 2019 in accordance with ASC Topic 842. Finance leases are not material to the consolidated financial statements.

The most significant impact of adopting ASC Topic 842 was the recognition of right-of-use assets and lease liabilities on the balance sheet for operating leases of $58.7 million as of January 1, 2019. The accounting for finance leases (formerly referred to as capital leases prior to the adoption of ASC Topic 842) remained substantially unchanged. The expense recognition for operating leases and finance leases under ASC Topic 842 is substantially consistent with ASC Topic 840 and the impact of the new standard is non-cash in nature. As a result, there is no significant impact on the Company’s results of operations or cash flows presented in the Company’s consolidated financial statements.

ASC Topic 815, Derivatives and Hedging, which was adopted by the Company on January 1, 2019, was amended to change the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results to simplify hedge accounting treatment and better align an entity’s risk management activities and financial reporting for hedging relationships. ASC Topic 815, as amended, also allows for the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a U.S. benchmark interest rate. The amendment did not have an impact on the consolidated financial statements.

The U.S. Securities and Exchange Commission (the “SEC”) issued Final Rule 33-10618, FAST Act Modernization and Simplification of Regulation S-K, (“Final Rule 33-10618”) in March 2019 to modernize and simplify certain disclosure requirements in Regulation S-K and the related rules and forms. Effective April 2, 2019, the final rule allows registrants to redact confidential information from most exhibits filed with the SEC without filing a confidential treatment request. Effective May 2, 2019, the final rule requires registrants to include the trading symbol for each class of registered securities on the cover page of certain SEC forms. The eXtensible Business Reporting Language (“XBRL”) reporting requirements of the final rule for tagging data on the cover page of certain SEC filings and the use of hyperlinks for information that is incorporated by reference and available on EDGAR became effective for the Company with this Quarterly Report on Form 10-Q.

Accounting Pronouncements Not Yet Adopted

Final Rule 33-10618 includes certain provisions to simplify certain annual disclosure requirements within the Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), Risk Factors, and Properties sections of Form 10-K. These provisions, which the Company will adopt for its 2019 Annual Report on Form 10-K, are not expected to have a significant impact on the Company’s consolidated financial statement disclosures.

ASC Subtopic 350-40, Intangibles – Goodwill and Other – Internal-Use Software: Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, (“ASC Subtopic 350-40”) was amended by the FASB in August 2018 and is effective for the Company beginning January 1, 2020. The amendments to ASC Subtopic 350-40 clarify the accounting treatment for implementation costs incurred by the customer in a cloud computing software arrangement. The amendments allow implementation costs of cloud computing arrangements to be capitalized using the same method prescribed by ASC Subtopic 350-40, Internal-Use Software. The amendments to ASC Subtopic 350-40 will be adopted on a prospective basis and are not expected to have an impact on the Company’s consolidated financial statements.

ASC Topic 820, Fair Value Measurement, was amended to modify the disclosure requirements of fair value measurements, primarily impacting the disclosures for Level 3 fair value measurements. The amendment is effective for the Company beginning January 1, 2020 and is not expected to have a significant impact on the Company’s financial statement disclosures.

ASC Topic 326, Financial Instruments – Credit Losses, (“ASC Topic 326”), was amended to improve the measurement of credit losses on financial instruments, including trade accounts receivable. The amendment is effective for the Company beginning January 1, 2020 and is not expected to have a significant impact on the Company’s consolidated financial statements.

Management believes there is no other new accounting guidance issued but not yet effective that is relevant to the Company’s current financial statements.

(3) Recorded at fair value as determined by quoted market prices (see amounts presented in the table of financial assets and liabilities measured at fair value within this Note).

(4) Recorded at amortized cost plus accrued interest, which approximates fair value. U.S. Treasury securities with a maturity date within 90 days of the purchase date are classified as cash equivalents. U.S. Treasury securities included in short-term investments are held-to-maturity investments with maturity dates of less than one year.

The Company’s long-term financial instruments are presented in the table of financial assets and liabilities measured at fair value within this Note.

Concentrations of Credit Risk of Financial Instruments

The Company is potentially subject to concentrations of credit risk related to its cash, cash equivalents, and short-term investments. The Company reduces credit risk by maintaining its cash deposits primarily in FDIC-insured accounts and placing its short-term investments primarily in FDIC-insured certificates of deposit. However, certain cash deposits and certificates of deposit may exceed federally insured limits. At June 30, 2019 and December 31, 2018, cash, cash equivalents, and short-term investments totaling $68.9 million and $94.7 million, respectively, were neither FDIC insured nor direct obligations of the U.S. government.

Fair Value Disclosure of Financial Instruments

Fair value disclosures are made in accordance with the following hierarchy of valuation techniques 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.

Fair value and carrying value disclosures of financial instruments are presented in the following table:

	June 30				December 31
	2019				2018

	$	282,054	$	285,456	$	291,409	$	291,560

(1) The revolving credit facility (the “Credit Facility”) carries a variable interest rate based on LIBOR, plus a margin, that is considered to be priced at market for debt instruments having similar terms and collateral requirements (Level 2 of the fair value hierarchy).

(2) Borrowings under the Company’s accounts receivable securitization program carry a variable interest rate based on LIBOR, plus a margin. The borrowings are considered to be priced at market for debt instruments having similar terms and collateral requirements (Level 2 of the fair value hierarchy).

(3) Fair value of the notes payable was determined using a present value income approach based on quoted interest rates from lending institutions with which the Company would enter into similar transactions (Level 2 of the fair value hierarchy).

(3) Included in other long-term assets or other long-term liabilities. The fair values of the interest rate swaps were determined by discounting future cash flows and receipts based on expected interest rates observed in market interest rate curves adjusted for estimated credit valuation considerations reflecting nonperformance risk of the Company and the counterparty, which are considered to be in Level 3 of the fair value hierarchy. The Company assessed Level 3 inputs as insignificant to the valuation at June 30, 2019 and December 31, 2018 and considers the interest rate swap valuations in Level 2 of the fair value hierarchy.

(4) Included in accrued expenses. At December 31, 2018, the fair value of the contingent consideration for an earn-out agreement related to the September 2016 acquisition of LDS represents the final accrued payment and was based on calculations performed for the earn-out period which ended August 31, 2018. In January 2019, final payment of the contingent consideration was released from an escrow account reported in other current assets in the consolidated balance sheets.

INCOME TAXES

NOTE D – INCOME TAXES

On December 22, 2017, H.R. 1/Public Law 115-97 which includes tax legislation titled Tax Cuts and Jobs Act (the “Tax Reform Act”) was signed into law. Effective January 1, 2018, the Tax Reform Act reduced the U.S. federal corporate tax rate from 35% to 21%. As a result of the Tax Reform Act, the Company recorded a provisional reduction of net deferred income tax liabilities of approximately $24.5 million at December 31, 2017, pursuant to the provisions of ASC Topic 740, Income Taxes, which requires the impact of tax law changes to be recognized in the period in which the legislation is enacted. An additional provisional reduction of net deferred income tax liabilities of $0.1 million and $2.6 million was recognized in the three and six months ended June 30, 2018, respectively, related to the reversal of temporary differences through the Company’s fiscal tax year end of February 28, 2018. State tax rates vary among states and average approximately 6.0% to 6.5%, although some state rates are higher and a small number of states do not impose an income tax. The effective tax rate was 27.4% and 27.1% for the three and six months ended June 30, 2019, respectively, and the effective tax benefit rate was 68.0% and 15.0% for the three and six months ended June 30, 2018, respectively.

In addition to the provisional effect on net deferred tax liabilities, the Company recorded a provisional reduction in current income tax expense of $1.3 million and $0.1 million at December 31, 2017 and June 30, 2018, respectively, as a result of the Tax Reform Act, to reflect the Company’s use of a fiscal year rather than a calendar year for U.S. income tax filing. Due to the fact that the Company’s fiscal tax year included the effective date of the rate change under the Tax Reform Act, taxes were required to be calculated by applying a blended rate to the taxable income for the taxable year ended February 28, 2018. The blended rate is calculated based on the ratio of days in the fiscal year prior to and after the effective date of the rate change. In computing total tax expense for the three and six months ended June 30, 2018, a 32.74% blended federal statutory rate was applied to the two months ended February 28, 2018, and a 21.0% federal statutory rate was

applied to the months of March 2018 through June 2018. A federal statutory rate of 21.0% was applied to the three and six months ended June 30, 2019.

The accounting for the income tax effects of the Tax Reform Act was completed as of December 31, 2018, and all amounts recorded were considered final.

For the three and six months ended June 30, 2019, the difference between the Company’s effective tax rate and the federal statutory rate primarily resulted from state income taxes, nondeductible expenses, changes in the cash surrender value of life insurance, and tax expense from the vesting of stock awards. For the six months ended June 30, 2018, the difference between the Company’s effective tax rate and the federal statutory rate primarily resulted from the $2.6 million provisional reduction of net deferred income tax liabilities, as previously discussed, and the $1.2 million alternative fuel tax credit related to the year ended December 31, 2017 which was recognized in first quarter 2018 due to the February 2018 passage of the Bipartisan Budget Act of 2018 which retroactively reinstated the alternative fuel tax credit that had previously expired on December 31, 2016. The difference between the Company’s effective tax rate and the federal statutory rate for the three and six months ended June 30, 2018 also resulted from state income taxes, nondeductible expenses, changes in tax valuation allowances, the tax benefit from the vesting of stock awards, and changes in the cash surrender value of life insurance.

As of June 30, 2019, the Company’s deferred tax liabilities, which will reverse in future years, exceeded the deferred tax assets. The Company evaluated the total deferred tax assets at June 30, 2019 and concluded that, other than for certain deferred tax assets related to state contribution carryforwards, the assets did not exceed the amount for which realization is more likely than not. In making this determination, the Company considered the future reversal of existing taxable temporary differences, future taxable income, and tax planning strategies. Valuation allowances for deferred tax assets totaled $0.1 million at June 30, 2019 and December 31, 2018.

The Company had reserves for uncertain tax positions of $1.0 million at June 30, 2019 and December 31, 2018.

In first quarter of 2019, the Company recorded a deferred tax asset of approximately $19.0 million related to operating lease liabilities and recorded a deferred tax liability of approximately $19.0 million related to operating lease right-of-use assets due to the adoption of ASC Topic 842.

The Company paid federal, state, and foreign income taxes of $8.9 million during the six months ended June 30, 2019, and paid $2.5 million of foreign and state income taxes during the six months ended June 30, 2018. The Company received refunds of less than $0.1 million of state income taxes and refunds of $1.1 million of federal and state income taxes that were paid in prior years during the six months ended June 30, 2019 and 2018, respectively.

NOTE E – LEASES

The Company leases, under finance and operating lease arrangements, certain facilities used primarily in the Asset-Based segment service center operations, certain revenue equipment used in the ArcBest segment operations, and certain other office equipment. Operating leases have remaining terms of less than 10 years, some of which include one or more options to renew, with renewal option terms up to five years, and some of which include options to terminate the leases within the next three years. The right-of-use assets and lease liabilities as of June 30, 2019 do not assume the option to early terminate any of the Company’s leases, and all renewal options that have been exercised or are reasonably certain to be exercised as of June 30, 2019 are included in the right-of-use assets and lease liabilities. Variable lease cost for operating leases consists of subsequent changes in CPI index, rent payments that are based on usage, and other lease related payments subject to change and not considered fixed payments. All fixed lease and non-lease component payments are combined in determining the right-of-use asset and lease liability.

The Company has a small number of finance leases recorded in property, plant and equipment and long-term debt related to structures and office equipment that are immaterial to the consolidated financial statements.

Financing Arrangements

Credit Facility

The Company has a revolving credit facility (the “Credit Facility”) under its Second Amended and Restated Credit Agreement (the “Credit Agreement”) with an initial maximum credit amount of $200.0 million, including a swing line facility in an aggregate amount of up to $20.0 million and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $20.0 million. The Company may request additional revolving commitments or incremental term loans thereunder up to an aggregate additional amount of $100.0 million, subject to certain additional conditions as provided in the Credit Agreement. As of June 30, 2019, the Company had available borrowing capacity of $130.0 million under the Credit Facility.

Principal payments under the Credit Facility are due upon maturity of the facility on July 7, 2022; however, borrowings may be repaid, at the Company’s discretion, in whole or in part at any time, without penalty, subject to required notice periods and compliance with minimum prepayment amounts. Borrowings under the Credit Agreement can either be, at the Company’s election: (i) at an alternate base rate (as defined in the Credit Agreement) plus a spread; or (ii) at a Eurodollar rate (as defined in the Credit Agreement) plus a spread. The applicable spread is dependent upon the Company’s Adjusted Leverage Ratio (as defined in the Credit Agreement). The Credit Agreement contains conditions, representations and

warranties, events of default, and indemnification provisions that are customary for financings of this type, including, but not limited to, a minimum interest coverage ratio, a maximum adjusted leverage ratio, and limitations on incurrence of debt, investments, liens on assets, certain sale and leaseback transactions, transactions with affiliates, mergers, consolidations, purchases and sales of assets, and certain restricted payments. The Company was in compliance with the covenants under the Credit Agreement at June 30, 2019.

Interest Rate Swaps

The Company has a five-year interest rate swap agreement with a $50.0 million notional amount maturing on January 2, 2020. The Company receives floating-rate interest amounts based on one-month LIBOR in exchange for fixed-rate interest payments of 1.85% over the life of the agreement. The interest rate swap mitigates interest rate risk by effectively converting $50.0 million of borrowings under the Credit Facility from variable-rate interest to fixed-rate interest with a per annum rate of 3.10% based on the margin of the Credit Facility as of June 30, 2019. The fair value of the interest rate swap of $0.1 million and $0.3 million was recorded in other long-term assets in the consolidated balance sheet at June 30, 2019 and December 31, 2018, respectively.

In June 2017, the Company entered into a forward-starting interest rate swap agreement with a $50.0 million notional amount which will start on January 2, 2020 upon maturity of the current interest rate swap agreement, and mature on June 30, 2022. The Company will receive floating-rate interest amounts based on one-month LIBOR in exchange for fixed-rate interest payments of 1.99% over the life of the agreement. The interest rate swap mitigates interest rate risk by effectively converting $50.0 million of borrowings under the Credit Facility from variable-rate interest to fixed-rate interest with a per annum rate of 3.24% based on the margin of the Credit Facility as of June 30, 2019. The fair value of the interest rate swap of $0.5 million was recorded in other long-term liabilities and $0.5 million was recorded in other long-term assets in the consolidated balance sheet at June 30, 2019 and December 31, 2018, respectively.

The unrealized gain on the interest rate swap instruments was reported as a component of accumulated other comprehensive loss, net of tax, in stockholders’ equity at June 30, 2019 and December 31, 2018, and the change in the unrealized income on the interest rate swaps for the three months and six months ended June 30, 2019 and 2018 was reported in other comprehensive loss, net of tax, in the consolidated statements of comprehensive income. The interest rate swaps are subject to certain customary provisions that could allow the counterparty to request immediate settlement of the fair value liability or asset upon violation of any or all of the provisions. The Company was in compliance with all provisions of the interest rate swap agreements at June 30, 2019.

Accounts Receivable Securitization Program

The Company’s accounts receivable securitization program, which matures on October 1, 2021, allows for cash proceeds of $125.0 million to be provided under the program and has an accordion feature allowing the Company to request additional borrowings up to $25.0 million, subject to certain conditions. Under this program, certain subsidiaries of the Company continuously sell a designated pool of trade accounts receivables to a wholly owned subsidiary which, in turn, may borrow funds on a revolving basis. This wholly owned consolidated subsidiary is a separate bankruptcy-remote entity, and its assets would be available only to satisfy the claims related to the lender’s interest in the trade accounts receivables. Borrowings under the accounts receivable securitization program bear interest based upon LIBOR, plus a margin, and an annual facility fee. The securitization agreement contains representations and warranties, affirmative and negative covenants, and events of default that are customary for financings of this type, including a maximum adjusted leverage ratio covenant. As of June 30, 2019, $40.0 million was borrowed under the program. The Company was in compliance with the covenants under the accounts receivable securitization program at June 30, 2019.

The accounts receivable securitization program includes a provision under which the Company may request and the letter of credit issuer may issue standby letters of credit, primarily in support of workers’ compensation and third-party casualty claims liabilities in various states in which the Company is self-insured. The outstanding standby letters of credit reduce the availability of borrowings under the program. As of June 30, 2019, standby letters of credit of $14.9 million have been issued under the program, which reduced the available borrowing capacity to $70.1 million.

Letter of Credit Agreements and Surety Bond Programs

As of June 30, 2019, the Company had letters of credit outstanding of $15.5 million (including $14.9 million issued under the accounts receivable securitization program). The Company has programs in place with multiple surety companies for the issuance of surety bonds in support of its self-insurance program. As of June 30, 2019, surety bonds outstanding related to the self-insurance program totaled $48.6 million.

Notes Payable

The Company has financed the purchase of certain revenue equipment, other equipment, and software through promissory note arrangements, including $20.5 million for revenue equipment and other equipment during the three months ended June 30, 2019.

Subsequent to June 30, 2019, the Company financed the purchase of an additional $17.2 million of revenue equipment through promissory note arrangements as of August 1, 2019.

Nonunion Defined Benefit Pension Plan

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 IRS regarding qualification of the plan termination. Benefit election forms were provided to plan participants during the fourth quarter of 2018 and participants could elect any form of payment allowed by the plan for immediate commencement of payment or defer payment until a later date. The plan began distributing immediate lump sum benefit payments related to the plan termination in fourth quarter 2018 and continued making these distributions during 2019. The plan received an extension from the Pension Benefit Guaranty Corporation (the “PBGC”) to allow additional time for the plan to administer the settlement of the remaining obligation for deferred benefits through the purchase of a nonparticipating annuity contract from an insurance company. The Company will make a cash contribution to the plan for the amount, if any, required to fund benefit distributions and annuity contract purchases in excess of plan assets.

The Company recognized pension settlement expense as a component of net periodic benefit cost of the nonunion defined benefit pension plan for the three and six months ended June 30, 2019 of $0.3 million (pre-tax), or $0.2 million (after-tax), and $1.6 million (pre-tax), or $1.2 million (after-tax), respectively, related to $3.0 million and $17.9 million of lump-sum benefit distributions from the plan for the three and six months ended June 30, 2019, respectively. For the three and six months ended June 30, 2018, pension settlement expense of $0.4 million (pre-tax), or $0.3 million (after-tax), and $1.1 million (pre-tax), or $0.8 million (after-tax), respectively, was recognized related to $3.7 million and $8.5 million of lump-sum distributions from the plan for the three and six months ended June 30, 2018, respectively. Pension settlement charges related to the plan termination, including those related to an annuity contract purchase are expected to occur in 2019.

In August 2019, the nonunion defined benefit pension plan received a preliminary bid for a nonparticipating annuity contract from an insurance company to settle the pension obligation related to the vested benefits of the remaining participants who were receiving monthly benefit payments from the plan or who did not elect to receive a lump sum benefit upon plan termination. Based on the most recently available actuarial information, including the preliminary bid received in August, nonunion pension settlement expense for the second half of 2019 is estimated to be approximately $2.0 million, or $1.5 million after-tax, and the Company could expect to make a cash contribution to the plan of approximately $7.0 million, which would be deductible for income tax purposes, to fund an annuity contract purchase and the remaining benefit distributions expected to be made from the plan in excess of plan assets. However, there can be no assurances in regards to the required cash funding or pension settlement charges, as the actual amounts are dependent on various factors and will be determined using updated actuarial data. Liquidation of plan assets and settlement of plan obligations for the nonunion defined benefit pension plan is expected to be completed in 2019.

The Company’s short-term rate of return assumption, net of estimated expenses expected to be paid from plan assets, utilized in determining nonunion defined benefit pension expense was lowered from 1.4% for first quarter 2019 to 0.0% for the second and third quarters of 2019, as estimated expenses expected to be paid from plan assets are expected to offset investment returns on plan assets which were held in money market mutual funds as of June 30, 2019.

The following table discloses the changes in benefit obligations and plan assets of the nonunion defined benefit pension plan for the six months ended June 30, 2019:

	Nonunion Defined

Multiemployer Plans

ABF Freight System, Inc. and certain other subsidiaries reported in the Company’s Asset-Based operating segment (“ABF Freight”) contribute to multiemployer pension and health and welfare plans, which have been established pursuant to the Taft-Hartley Act, to provide benefits for its contractual employees. ABF Freight’s contributions generally are based on the time worked by its contractual employees, in accordance with the 2018 ABF NMFA and other related supplemental agreements. ABF Freight recognizes as expense the contractually required contributions for each period and recognizes as a liability any contributions due and unpaid.

The 25 multiemployer pension plans to which ABF Freight contributes vary greatly in size and in funded status. Contribution obligations to these plans are generally specified in the 2018 ABF NMFA, which will remain in effect through June 30, 2023. The funding obligations to the pension plans are intended to satisfy the requirements imposed by the Pension Protection Act of 2006, which was permanently extended by the Multiemployer Pension Reform Act (the “Reform Act”) included in the Consolidated and Further Continuing Appropriations Act of 2015. Provisions of the Reform Act include, among others, providing qualifying plans the ability to self-correct funding issues, subject to various requirements and restrictions, including applying to the U.S. Department of the Treasury for the reduction of certain accrued benefits. Through the term of its current collective bargaining agreement, ABF Freight’s contribution obligations generally will be satisfied by making the specified contributions when due. However, the Company cannot determine with any certainty the contributions that will be required under future collective bargaining agreements for ABF Freight’s contractual employees. If ABF Freight was to completely withdraw from certain multiemployer pension plans, under current law, ABF Freight would have material liabilities for its share of the unfunded vested liabilities of each such plan.

Approximately one half of ABF Freight’s total contributions to multiemployer pension plans are made to the Central States, Southeast and Southwest Areas Pension Plan (the “Central States Pension Plan”). As set forth in the 2018 Annual Funding Notice for the Central States Pension Plan, the funded percentage of the plan was 27.2% as of January 1, 2018. ABF Freight received a Notice of Critical and Declining Status for the Central States Pension Plan dated March 29, 2019, in which the plan’s actuary certified that, as of January 1, 2019, the plan is in critical and declining status, as defined by the Reform Act. Critical and declining status is applicable to critical status plans that are projected to become insolvent anytime within the next 14 plan years, or if the plan is projected to become insolvent within the next 19 plan years and either the plan’s ratio of inactive participants to active participants exceeds two to one or the plan’s funded percentage is less than 80%.

As more fully described in Note I to the consolidated financial statements in Item 8 of the Company’s 2018 Annual Report on Form 10-K, ABF Freight’s multiemployer pension plan obligation with the New England Teamsters and Trucking Industry Pension Fund (the “New England Pension Fund”) was restructured under a transition agreement effective on August 1, 2018, which resulted in a related withdrawal liability for which ABF Freight recognized a one-time charge of $37.9 million (pre-tax) as of June 30, 2018. In accordance with the transition agreement, ABF Freight made an initial lump sum cash payment of $15.1 million in third quarter 2018 and the remainder of the withdrawal liability, which had an initial aggregate present value of $22.8 million, will be settled with monthly payments to the New England Pension Fund over a period of 23 years. In accordance with current tax law, these payments are deductible for income taxes when paid.

As of June 30, 2019, the outstanding withdrawal liability totaled $22.3 million, of which $0.6 million and $21.7 million was recorded in accrued expenses and other long-term liabilities, respectively. The fair value of the obligation was $24.4 million at June 30, 2019, which is equal to the present value of the future withdrawal liability payments, discounted at a 3.6% interest rate determined using the 20-year U.S. Treasury rate plus a spread (Level 2 of the fair value hierarchy).

The multiemployer plan administrators have provided to the Company no other significant changes in information related to multiemployer plans from the information disclosed in the Company’s 2018 Annual Report on Form 10-K.

Under the two-class method of calculating earnings per share, dividends paid and a portion of undistributed net income, but not losses, are allocated to unvested RSUs that receive dividends, which are considered participating securities. Beginning with 2015 grants, the RSU agreements were modified to remove dividend rights; therefore, the RSUs granted subsequent to 2015 are not participating securities. For the three- and six-month periods ended June 30, 2019 and 2018, outstanding stock awards of 0.2 million and 0.1 million, respectively, were not included in the diluted earnings per share calculation because their inclusion would have the effect of increasing the earnings per share.

OPERATING SEGMENT DATA

OPERATING SEGMENT DATA

OPERATING SEGMENT DATA

NOTE K – OPERATING SEGMENT DATA

The Company uses the “management approach” to determine its reportable operating segments, as well as to determine the basis of reporting the operating segment information. The management approach focuses on financial information that the Company’s management uses to make operating decisions. Management uses revenues, operating expense categories, operating ratios, operating income, and key operating statistics to evaluate performance and allocate resources to the Company’s operations.

Shared services represent costs incurred to support all segments, including sales, pricing, customer service, marketing, capacity sourcing functions, human resources, financial services, information technology, legal, and other company-wide services. Certain overhead costs are not attributable to any segment and remain unallocated in “Other and eliminations.” Included in unallocated costs are expenses related to investor relations, legal, the ArcBest Board of Directors, and certain technology investments. Shared services costs attributable to the operating segments are predominantly allocated based upon estimated and planned resource utilization-related metrics such as estimated shipment levels, number of pricing proposals, or number of personnel supported. The bases for such charges are modified and adjusted by management when necessary or appropriate to reflect fairly and equitably the actual incidence of cost incurred by the operating segments. Management believes the methods used to allocate expenses are reasonable.

The Company’s reportable operating segments are impacted by seasonal fluctuations which affect tonnage, shipment or service event levels, and demand for services, as described below; therefore, operating results for the interim periods presented may not necessarily be indicative of the results for the fiscal year.

The Company’s reportable operating segments are as follows:

● The Asset-Based segment includes the results of operations of ABF Freight System, Inc. and certain other subsidiaries. The segment operations include national, inter-regional, and regional transportation of general commodities through standard, expedited, and guaranteed LTL services. In addition, the segment operations include freight transportation related to certain consumer household goods self-move services.

Freight shipments and operating costs of the Asset-Based segment can be adversely affected by inclement weather conditions. The second and third calendar quarters of each year usually have the highest tonnage levels while the first quarter generally has the lowest, although other factors, including the state of the U.S. and global economies, may influence quarterly freight tonnage levels.

● The ArcBest segment includes the results of operations of the Company’s service offerings in ground expedite, truckload, truckload-dedicated, intermodal, household goods moving, managed transportation, warehousing and distribution, and international freight transportation for air, ocean, and ground.

ArcBest segment operations are influenced by seasonal fluctuations that impact customers’ supply chains. The second and third calendar quarters of each year usually have the highest shipment levels while the first quarter generally has the lowest, although other factors, including the state of the U.S. and global economies and available capacity in the market, may impact quarterly business levels. Shipments of the ArcBest segment may decline during winter months because of post-holiday slowdowns, but expedite shipments can be subject to short-term increases depending on the impact of weather disruptions to customers’ supply chains. Plant shutdowns during summer months may affect shipments for automotive and manufacturing customers of the ArcBest segment, but severe weather events can result in higher demand for expedite services. Moving services of the ArcBest segment are impacted by seasonal fluctuations, generally resulting in higher business levels in the second and third quarters as the demand for moving services is typically stronger in the summer months.

● FleetNet includes the results of operations of FleetNet America, Inc. and certain other subsidiaries that provide roadside assistance and maintenance management services for commercial vehicles through a network of third-party service providers. FleetNet also provides services to the Asset-Based and ArcBest segments. Approximately 19% and 16% of FleetNet’s revenues for the three and six months ended June 30, 2019, respectively, are for services provided to the Asset-Based and ArcBest segments compared to approximately 3% for the same periods of 2018.

Emergency roadside service events of the FleetNet segment are favorably impacted by extreme weather conditions that affect commercial vehicle operations, and the segment’s results of operations will be influenced by seasonal variations in service event volume.

The Company’s other business activities and operating segments that are not reportable include ArcBest Corporation and certain other subsidiaries. Certain costs incurred by the parent holding company and the Company’s shared services subsidiary are allocated to the reporting segments. The Company eliminates intercompany transactions in consolidation. However, the information used by the Company’s management with respect to its reportable segments is before intersegment eliminations of revenues and expenses.

Further classifications of operations or revenues by geographic location are impracticable and, therefore, are not provided. The Company’s foreign operations are not significant.

The following tables reflect reportable operating segment information:

LEGAL PROCEEDINGS, ENVIRONMENTAL MATTERS, AND OTHER EVENTS

LEGAL PROCEEDINGS, ENVIRONMENTAL MATTERS, AND OTHER EVENTS

NOTE L – LEGAL PROCEEDINGS, ENVIRONMENTAL MATTERS, AND OTHER EVENTS

The Company is involved in various legal actions arising in the ordinary course of business. The Company maintains liability insurance against certain risks arising out of the normal course of its business, subject to certain self-insured retention limits. The Company routinely establishes and reviews the adequacy of reserves for estimated legal, environmental, and self-insurance exposures. While management believes that amounts accrued in the consolidated financial statements are adequate, estimates of these liabilities may change as circumstances develop. Considering amounts recorded, routine legal matters are not expected to have a material adverse effect on the Company’s financial condition, results of operations, or cash flows.

Environmental Matters

The Company’s subsidiaries store fuel for use in tractors and trucks in 61 underground tanks located in 18 states. Maintenance of such tanks is regulated at the federal and, in most cases, state levels. The Company believes it is in substantial compliance with all such regulations. The Company’s underground storage tanks are required to have leak detection systems. The Company is not aware of any leaks from such tanks that could reasonably be expected to have a material adverse effect on the Company.

The Company has received notices from the Environmental Protection Agency and others that it has been identified as a potentially responsible party under the Comprehensive Environmental Response Compensation and Liability Act, or other federal or state environmental statutes, at several hazardous waste sites. After investigating the Company’s involvement in waste disposal or waste generation at such sites, the Company has either agreed to de minimis settlements or determined that its obligations, other than those specifically accrued with respect to such sites, would involve immaterial monetary liability, although there can be no assurances in this regard.

At June 30, 2019 and December 31, 2018, the Company’s reserve, which was reported in accrued expenses, for estimated environmental cleanup costs of properties currently or previously operated by the Company totaled $0.6 million. 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.

ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION (Policies)

6 Months Ended

Jun. 30, 2019

ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION

Financial Statement Presentation

Financial Statement Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) pertaining to interim financial information. Accordingly, these interim financial statements do not include all information or footnote disclosures required by accounting principles generally accepted in the United States for complete financial statements and, therefore, should be read in conjunction with the audited financial statements and accompanying notes included in the Company’s 2018 Annual Report on Form 10-K and other current filings with the SEC. In the opinion of management, all adjustments (which are of a normal and recurring nature) considered necessary for a fair presentation have been included.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual amounts may differ from those estimates.

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 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. 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 finance and operating lease arrangements, certain facilities used primarily in the Asset-Based segment service center operations, certain revenue equipment used in the ArcBest segment operations, and certain other office equipment. The Company adopted Accounting Standards Codification (“ASC”) Topic 842, Leases, (“ASC Topic 842”) effective January 1, 2019. In accordance with ASC Topic 842, right-of-use assets and lease liabilities for operating leases are recorded on the balance sheet and the related lease expense is recorded on a straight-line basis over

the lease term in operating expenses. Included in lease expense are any variable lease payments incurred in the period that were not included in the initial lease liability. For financial reporting purposes, right-of-use assets held under finance leases are amortized over their estimated useful lives on the same basis as owned assets, and leasehold improvements associated with assets utilized under finance 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 finance leases is included in depreciation expense. Obligations under the finance lease arrangements are included in long-term debt.

The short-term lease exemption was elected under ASC Topic 842 for all classes of assets to include real property, revenue equipment, and service, office, and other equipment. The Company adopted the policy election as a lessee for all classes of assets to account for each lease component and its related non-lease component(s) as a single lease component. In determining the discount rate, the Company uses the rate implicit in the lease if that rate is readily determinable when entering into a lease as a lessee. If the rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate, determined by the price of a fully collateralized loan with similar terms based on current market rates.

For contracts entered into on or after the effective date, an assessment is made as to whether the contract is, or contains, a lease at the inception of a contract. The assessment is based on: (1) whether the contract involves the use of a distinct identified asset; (2) whether the Company obtains the right to substantially all the economic benefit from the use of the asset throughout the period; and (3) whether the Company has the right to direct the use of the asset. For all operating leases that meet the scope of ASC Topic 842, a right-of-use asset and a lease liability are recognized. The right-of-use asset is measured as the initial amount of the lease liability, plus any initial direct costs incurred, less any prepayments prior to commencement or lease incentives received. The lease liability is initially measured at the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s secured incremental borrowing rate for the same term as the underlying lease. Lease payments included in the measurement of the lease liability are comprised of the following: (1) the fixed noncancelable lease payments, (2) payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and (3) payments for early termination options unless it is reasonably certain the lease will not be terminated early. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement and included in the measurement of the initial lease liability. Additional payments based on the change in an index or rate are recorded as a period expense when incurred. Lease modifications result in remeasurement of the lease liability.

Accounting Pronouncements

Adopted Accounting Pronouncements

ASC Topic 842, which was adopted by the Company effective 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. The Company elected the modified retrospective method of applying the transition provisions at the beginning of the period of adoption and, as a result, has not adjusted comparative period financial information and has not included the new lease disclosures for periods before the effective date. Prior period amounts continue to be reported under the Company’s historical accounting in accordance with the previous lease guidance included in ASC Topic 840.

The Company has excluded short-term leases from accounting under ASC Topic 842 and has elected the package of practical expedients as permitted under the transition guidance, which allowed the Company to not reassess: (1) whether contracts are, or contain, leases; (2) lease classification; and (3) capitalization of initial direct costs. For contracts entered into on or after the effective date, an assessment is made as to whether the contract is, or contains, a lease at the inception of a contract. Consistent with the package of practical expedients elected, leases entered into prior to January 1, 2019, are accounted for under ASC Topic 840 and were not reassessed. For all classes of assets, the policy election was made to account for each lease component and its related non-lease component(s) as a single lease component. The election to not recognize right-of-use assets and lease liabilities for short-term leases that have a term of 12 months or less did not have a material effect on the right-of-use assets and lease liabilities.

The majority of the Company’s lease portfolio consists of real property operating leases related to facilities used in the Asset-Based segment service center operations. The lease portfolio also includes operating leases related to certain revenue equipment used in the ArcBest segment operations as well as a small number of office equipment finance leases. Management has recorded the right-of-use assets and associated lease liabilities for operating leases on the consolidated

balance sheet as of June 30, 2019 in accordance with ASC Topic 842. Finance leases are not material to the consolidated financial statements.

The most significant impact of adopting ASC Topic 842 was the recognition of right-of-use assets and lease liabilities on the balance sheet for operating leases of $58.7 million as of January 1, 2019. The accounting for finance leases (formerly referred to as capital leases prior to the adoption of ASC Topic 842) remained substantially unchanged. The expense recognition for operating leases and finance leases under ASC Topic 842 is substantially consistent with ASC Topic 840 and the impact of the new standard is non-cash in nature. As a result, there is no significant impact on the Company’s results of operations or cash flows presented in the Company’s consolidated financial statements.

ASC Topic 815, Derivatives and Hedging, which was adopted by the Company on January 1, 2019, was amended to change the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results to simplify hedge accounting treatment and better align an entity’s risk management activities and financial reporting for hedging relationships. ASC Topic 815, as amended, also allows for the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a U.S. benchmark interest rate. The amendment did not have an impact on the consolidated financial statements.

The U.S. Securities and Exchange Commission (the “SEC”) issued Final Rule 33-10618, FAST Act Modernization and Simplification of Regulation S-K, (“Final Rule 33-10618”) in March 2019 to modernize and simplify certain disclosure requirements in Regulation S-K and the related rules and forms. Effective April 2, 2019, the final rule allows registrants to redact confidential information from most exhibits filed with the SEC without filing a confidential treatment request. Effective May 2, 2019, the final rule requires registrants to include the trading symbol for each class of registered securities on the cover page of certain SEC forms. The eXtensible Business Reporting Language (“XBRL”) reporting requirements of the final rule for tagging data on the cover page of certain SEC filings and the use of hyperlinks for information that is incorporated by reference and available on EDGAR became effective for the Company with this Quarterly Report on Form 10-Q.

Accounting Pronouncements Not Yet Adopted

Final Rule 33-10618 includes certain provisions to simplify certain annual disclosure requirements within the Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), Risk Factors, and Properties sections of Form 10-K. These provisions, which the Company will adopt for its 2019 Annual Report on Form 10-K, are not expected to have a significant impact on the Company’s consolidated financial statement disclosures.

ASC Subtopic 350-40, Intangibles – Goodwill and Other – Internal-Use Software: Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement, (“ASC Subtopic 350-40”) was amended by the FASB in August 2018 and is effective for the Company beginning January 1, 2020. The amendments to ASC Subtopic 350-40 clarify the accounting treatment for implementation costs incurred by the customer in a cloud computing software arrangement. The amendments allow implementation costs of cloud computing arrangements to be capitalized using the same method prescribed by ASC Subtopic 350-40, Internal-Use Software. The amendments to ASC Subtopic 350-40 will be adopted on a prospective basis and are not expected to have an impact on the Company’s consolidated financial statements.

ASC Topic 820, Fair Value Measurement, was amended to modify the disclosure requirements of fair value measurements, primarily impacting the disclosures for Level 3 fair value measurements. The amendment is effective for the Company beginning January 1, 2020 and is not expected to have a significant impact on the Company’s financial statement disclosures.

ASC Topic 326, Financial Instruments – Credit Losses, (“ASC Topic 326”), was amended to improve the measurement of credit losses on financial instruments, including trade accounts receivable. The amendment is effective for the Company beginning January 1, 2020 and is not expected to have a significant impact on the Company’s consolidated financial statements.

Management believes there is no other new accounting guidance issued but not yet effective that is relevant to the Company’s current financial statements.
