ARCBEST CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

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

ArcBest Corporation® (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, 2017. As part of our corporate restructuring (further described in “Financial Statement Presentation” within this Note), effective January 1, 2017, certain nonunion sales, pricing, customer service, marketing, and capacity sourcing employees were transferred to our corporate shared services departments (reported in “Other and eliminations”), which increased the percentage of union employees within the Asset-Based segment. As of June 2017, approximately 83% of the Asset-Based segment’s employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which extends through March 31, 2018. The ABF NMFA included a 7% wage rate reduction upon the November 3, 2013 implementation date, followed by wage rate increases of 2% on July 1 in each of the next three years, which began in 2014, and a 2.5% increase on July 1, 2017; a one-week reduction in annual compensated vacation effective for employee anniversary dates on or after April 1, 2013; the option to expand the use of purchased transportation; and increased flexibility in labor work rules. The ABF NMFA and the related supplemental agreements provide for continued contributions to various multiemployer health, welfare, and pension plans maintained for the benefit of the Asset-Based segment’s employees who are members of the IBT. The estimated net effect of the November 3, 2013 wage rate reduction and the benefit rate increase which was applied retroactively to August 1, 2013 was an initial reduction of approximately 4% to the combined total contractual wage and benefit rate under the ABF NMFA. Following the initial reduction, the combined contractual wage and benefit contribution rate under the ABF NMFA is estimated to increase approximately 2.5% on a compounded annual basis throughout the contract period which extends through March 31, 2018.

On September 2, 2016, the ArcBest segment acquired Logistics & Distribution Services, LLC (“LDS”), a private logistics and distribution company, in a transaction valued at $25.0 million (subject to post-closing adjustments), reflecting net cash consideration of $17.0 million paid at closing and an additional $8.0 million of contingent consideration to be paid over the two years following the acquisition upon the achievement of certain financial targets. As the LDS acquisition is not significant to the Company’s consolidated operating results and financial condition, pro forma financial information and the purchase price allocations of acquired assets and liabilities have not been presented. The results of the acquired operations subsequent to the acquisition date have been included in the accompanying consolidated financial statements.The Company is in the process of making a final determination of the value of acquired assets and liabilities for the LDS transaction and the provisional measurements are subject to change during the measurement period.

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 “Commission”) 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 2016 Annual Report on Form 10-K and other current filings with the Commission. In the opinion of management, all adjustments (which are of a normal and recurring nature) considered necessary for a fair presentation have been included.

8

Certain restatements have been made to the prior year’s operating segment data to conform to the current year presentation, reflecting the realignment of the Company’s organizational structure as announced on November 3, 2016. Under the new structure, the segments previously reported as Premium Logistics (Panther), Transportation Management (ABF Logistics), and Household Goods Moving Services (ABF Moving) are consolidated as a single Asset-Light logistics operation under ArcBest. Segment revenues and expenses were adjusted to eliminate certain intercompany charges consistent with the manner in which they are reported under the new corporate structure. Certain intercompany charges among the previously reported Panther, ABF Logistics, and ABF Moving segments which were previously eliminated in the “Other and eliminations” line, are now eliminated within the ArcBest segment. There was no impact on the Company’s consolidated revenues, operating expenses, operating income, or earnings per share as a result of the restatements.

Certain reclassifications have been made to the prior year’s consolidated financial statements to conform to the current year presentation. The insurance receivable for the amount of workers’ compensation and third-party casualty claims in excess of self-insurance retention limits, which was previously offset against the reserve included in accrued expenses, has been reclassed to other accounts receivable, resulting in an $8.7 million increase in other accounts receivable and a corresponding increase in accrued expenses in the consolidated balance sheet at December 31, 2016. Amounts totaling $18.6 million related to certain service centers of the Company’s Asset-Based operations previously recorded in leasehold improvements were reclassed to land and structures in the consolidated balance sheet at December 31, 2016. These reclassifications were previously reported in the Company’s first quarter 2017 Quarterly Report on Form 10-Q. The prior period impact of the reclassification of the insurance receivable is also reflected in the consolidated statements of cash flows for the six months ended June 30, 2016.

Other reclassifications were made to the consolidated financial statements to apply the provisions of accounting pronouncements adopted during the first quarter of 2017 related to deferred income taxes, share-based compensation, and cash flow classification (see Adopted Accounting Pronouncements within this Note). The Company’s deferred tax assets were reclassed, by jurisdiction, from current to long-term in the consolidated balance sheets. The net change in restricted cash previously presented in financing activities of the Company’s consolidated statements of cash flows was removed and restricted cash was included in the reconciliation of beginning- and end-of-period totals of cash and cash equivalents and restricted cash. Cash paid by the Company when directly withholding shares from an employee’s share-based compensation award for tax-withholding purposes was reclassified from an operating activity within changes in income taxes to a financing activity in the consolidated statements of cash flows. There was no impact on the Company’s consolidated revenues, operating expenses, operating income, or earnings per share as a result of the reclassifications.

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 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 2016 Annual Report on Form 10-K. The following policy became effective for the Company during the six months ended June 30, 2017.

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

9

Share based awards are amortized to compensation expense on a straight line basis over the vesting period of awards or over the period to which the recipient first becomes eligible for retirement, whichever is shorter, with vesting accelerated upon death or disability. The Company recognizes forfeitures as they occur.

Adopted Accounting Pronouncements

In the first quarter of 2017, the Company adopted guidance issued by the Financial Accounting Standards Board (the “FASB”) which amended Accounting Standards Codification (“ASC”) Topic 740 with the addition of Balance Sheet Classification of Deferred Taxes.  The amendment was retrospectively adopted and resulted in reclassifications to the consolidated balance sheets to present all deferred tax assets and liabilities as noncurrent by jurisdiction.

In the first quarter of 2017, the Company adopted an amendment to ASC Topic 718, Compensation – Stock Compensation, which requires the income tax effects of awards to be recognized in the statement of operations when awards vest or are settled and allows employers to make a policy election to account for forfeitures as they occur. As a result of applying the provisions of the amendment, the Company recognized a $0.2 million cumulative effect adjustment to the opening balance of retained earnings as previously disclosed in the Company’s first quarter 2017 Quarterly Report on Form 10‑Q. The Company also made a policy election to account for forfeitures as they occur. The Company may experience volatility in its income tax provision as a result of recording all excess tax benefits and tax deficiencies in the income statement upon settlement of awards, which is primarily during the second quarter of each year. This provision of the amendment related to recognition of excess tax benefits and tax deficiencies was adopted prospectively; therefore, the prior period has not been adjusted for this provision. Cash paid by the Company to taxing authorities on the employee’s behalf for withheld shares was reclassified from an operating activity within changes in accounts payable, accrued expenses, and other liabilities to a financing activity in the consolidated statements of cash flows. The other provisions of the adopted amendment did not have a significant impact on the Company’s consolidated financial statements.

In the first quarter of 2017, the Company also adopted amendments to ASC Topic 230, Statement of Cash Flows, which provide classification guidance for restricted cash and certain cash receipts and cash payments presented in the statement of cash flows. The retrospective adoption of the amendments resulted in reclassification to the consolidated statement of cash flows to include restricted cash in the reconciliation of beginning- and end-of-period totals of cash and cash equivalents. Proceeds from the settlement of corporate-owned life insurance policies will be classified as cash provided by investing activities, and cash payments for premiums on such insurance policies will be classified as cash used in operating activities in the consolidated statements of cash flows.

Accounting Pronouncements Not Yet Adopted

ASC Topic 606, which amends the guidance in former ASC Topic 605, Revenue Recognition, provides a single comprehensive revenue recognition model for all contracts with customers and contains principles to apply to determine the measurement of revenue and timing of when it is recognized. The standard is effective for the Company on January 1, 2018. The Company is in the process of contract review and documentation in preparation for adopting the revenue recognition standard. The Company plans to adopt this standard on the modified retrospective basis and does not expect a significant impact on the consolidated financial statements.

An amendment to ASC Topic 715, Compensation – Retirement Benefits will require the service cost component of net benefit cost related to benefit plans accounted for under ASC Topic 715 to be included in the same line item or items as other compensation costs arising from services rendered by the related employees and will allow only the service cost component of the net benefit cost to be eligible for capitalization of internal costs. The amendment will also require the other components of net benefit cost, including pension settlement expense, to be presented in other income (costs) rather than in operating income. The amendment is effective for the Company beginning January 1, 2018.

ASC Topic 718 Compensation-Stock Compensation, was amended to provide guidance about which changes to the terms or conditions of a share-based payment award require the application of modification accounting. The amendment is effective for the Company beginning January 1, 2018 and is not expected to have a significant impact on the consolidated financial statements.

10

ASC Topic 842, Leases, which is effective for the Company beginning January 1, 2019, will require leases with a term greater than twelve months to be reflected as liabilities with associated right-of-use assets in the Company’s consolidated balance sheet. The Company is evaluating the impact of the new standard, which is required to be adopted on the modified retrospective basis, on the consolidated financial statements and disclosures.

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

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, 2017 and December 31, 2016, cash and cash equivalents totaling $46.0 million and $39.9 million, respectively, were not FDIC insured.

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:

⁽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 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, 2017 and December 31, 2016 and considers the interest rate swap valuation in Level 2 of the fair value hierarchy.

⁽⁴⁾ Included in accrued expenses and other long-term liabilities, based on when expected payouts become due. The estimated fair value of contingent consideration for an earn-out agreement related to the September 2016 acquisition of LDS was determined by assessing Level 3 inputs with a discounted cash flow approach using various probability-weighted scenarios. The Level 3 assessments utilize a Monte Carlo simulation with inputs including scenarios of estimated revenues and gross margins to be achieved for the applicable performance periods, probability weightings assigned to the performance scenarios, and the discount rate applied, which was 11.9% and 12.3% as of June 30, 2017 and December 31, 2016, respectively. Subsequent changes to the fair value as a result of recurring assessments will be recognized in operating income.

NOTE D – INCOME TAXES

The Company’s statutory federal tax rate is 35%. 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 34.6% and 27.1% for the three and six months ended June 30, 2017, respectively, and 37.5% and 37.8% for the three and six months ended June 30, 2016, respectively.

For the three and six months ended June 30, 2017 and 2016, the difference between the Company’s effective tax rate and the federal statutory rate primarily results from state income taxes, nondeductible expenses, changes in deferred tax valuation allowances, and changes in the cash surrender value of life insurance. The three- and six-month period ended June 30, 2016 reflects a benefit of 1.9% and 8.6%, respectively, related to the alternative fuel tax credit which expired December 31, 2016.

In the first quarter of 2017, the Company adopted an amendment to ASC Topic 718, Compensation – Stock Compensation, which requires the income tax effects of awards to be recognized in the statement of operations when awards vest or are settled and allows employers to make a policy election to account for forfeitures as they occur. The Company may experience volatility in its income tax provision as a result of recording all excess tax benefits and tax deficiencies in the income statement upon settlement of awards, which is primarily during the second quarter of each year. As a result of applying the provisions of the amendment beginning in the first quarter of 2017, the tax rate for the three and six months ended June 30, 2017 reflects a benefit of 4.8% and 10.8%, respectively.

As of June 30, 2017, 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, 2017 and concluded that, other than for certain deferred tax assets related to foreign net operating loss and 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, taxable income in carryback years, future taxable income, and tax planning strategies.

The Company paid state and foreign income taxes of $0.4 million and $2.2 million during the six months ended June 30, 2017 and 2016, respectively. During the six months ended June 30, 2017 and 2016 the Company received refunds of $0.1 million and $10.8 million, respectively, of federal and state income taxes that were paid in prior years.

Financing Arrangements

Credit Facility

The Company has a revolving credit facility (the “Credit Facility”) under its credit agreement which was amended and restated on January 2, 2015 (the “Amended and Restated Credit Agreement”). The Credit Facility, which matures on January 2, 2020, has an initial maximum credit amount of $150.0 million, including a swing line facility 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 Credit Facility allows the Company to request additional revolving commitments or incremental term loans thereunder up to an aggregate additional amount of $75.0 million, subject to certain additional conditions as provided in the Amended and Restated Credit Agreement. Principal payments under the Credit Facility are due upon maturity; 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 Amended and Restated Credit Agreement can either be, at the Company’s election: (i) at an alternate base rate (as defined in the Amended and Restated Credit Agreement) plus a spread; or (ii) at a Eurodollar rate (as defined in the Amended and Restated Credit Agreement) plus a spread. The applicable spread is dependent upon the Company’s adjusted leverage ratio (as defined in the Amended and Restated Credit Agreement). The Amended and Restated 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 Amended and Restated Credit Agreement at June 30, 2017.

In July 2017, the Company amended and extended its credit agreement (the “Second Amended and Restated Credit Agreement”) to increase the initial maximum credit amount of its Credit Facility from $150.0 million to $200.0 million, including a swing line facility and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $20.0 million, and to increase the additional revolving commitments or incremental term loans the Company may request under the facility from $75.0 million to $100.0 million. The maturity date of the Credit Facility was extended to July 7, 2022. The covenants and conditions of the Second Amended and Restated Credit Agreement are consistent with the previously amended credit agreement.

Interest Rate Swap

The Company has an 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 interest rate swap 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 3.35% based on the margin of the Credit Facility as of June 30, 2017. The fair value of the interest rate swap of $0.3 million and $0.5 million was recorded in other long-term liabilities in the consolidated balance sheet at June 30, 2017 and December 31, 2016, respectively.

17

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 interest rate swap 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 3.49% based on the margin of the Credit Facility as of June 30, 2017. The fair value of the interest rate swap of $0.2 million was recorded in other long-term assets in the consolidated balance sheet at June 30, 2017.

The unrealized loss 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, 2017 and December 31, 2016, and the change in the unrealized income (loss) on the interest rate swaps for the three and six months ended June 30, 2017 and 2016 was reported in other comprehensive loss, net of tax, in the consolidated statement of comprehensive income. The interest rate swaps are subject to certain customary provisions that could allow the counterparty to request immediate payment of the fair value liability 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, 2017.

Accounts Receivable Securitization Program

In March 2017, the Company entered into a second amendment to extend the maturity date of its accounts receivable securitization program until April 1, 2020 and increase the amount of cash proceeds provided under the facility from $100.0 million to $125.0 million, with 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. In April2017, the Company borrowed $10.0 million under the accounts receivable securitization program. As of June 30, 2017, $45.0 million was borrowed under the program. The Company was in compliance with the covenants under the accounts receivable securitization program as of June 30, 2017.

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, 2017, standby letters of credit of $19.0 million have been issued under the program, which reduced the available borrowing capacity to $61.0 million.

Letter of Credit Agreements and Surety Bond Programs

As of June 30, 2017, the Company had letters of credit outstanding of $19.6 million (including $19.0 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, 2017, surety bonds outstanding related to the self-insurance program totaled $59.4 million.

Notes Payable and Capital Leases

The Company has financed the purchase of certain revenue equipment, other equipment, and software through promissory note arrangements, including $37.9 million and $38.6 million for revenue equipment and software during the three and six months ended June 30, 2017, respectively.

⁽¹⁾ The Company amortizes actuarial losses over the average remaining active service period of the plan participants and does not use a corridor approach.

Nonunion Defined Benefit Pension Plan

The Company’s nonunion defined benefit pension plan covers substantially all noncontractual employees hired before January 1, 2006. In June 2013, the Company amended the nonunion defined benefit pension plan to freeze the participants’ final average compensation and years of credited service as of July 1, 2013. The plan amendment did not impact the vested benefits of retirees or former employees whose benefits have not yet been paid from the plan. Effective July 1, 2013, participants of the nonunion defined benefit pension plan who were active employees of the Company became eligible for the discretionary defined contribution feature of the Company’s nonunion 401(k) and defined contribution plan in which all eligible noncontractual employees hired subsequent to December 31, 2005 also participate.

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, 2017 of $0.7 million (pre-tax), or $0.5 million (after-tax), and $2.7 million (pre-tax), or $1.7 million (after-tax), respectively, related to $4.9 million and $9.7 million of lump-sum benefit distributions from the plan for the three and six months ended June 30, 2017, respectively, which included a $7.6 million purchase during the first quarter 2017 of a nonparticipating annuity contract from an insurance company to settle the pension obligation related to the vested benefits of approximately 50 plan participants and beneficiaries receiving monthly benefit payments at the time of the contract purchase. For the three and six months ended June 30, 2016, pension settlement expense of $0.6 million (pre-tax), or $0.3 million (after-tax), and $1.5 million (pre-tax), or $0.9 million (after-tax), respectively, was recognized related to $2.7 million and $7.2 million of lump-sum distributions from the plan for the same respective periods. Upon recognition of pension settlement expense, a corresponding reduction in the unrecognized net actuarial loss of the plan is recorded. The remaining pre-tax unrecognized net actuarial loss will continue to be

19

amortized over the average remaining future years of service of the active plan participants. The Company will incur additional quarterly settlement expense related to lump-sum distributions from the nonunion defined benefit pension plan during the remainder of 2017.

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, 2017:

⁽¹⁾ Impacted by actuarial increases in the valuation of participant data as of January 1, 2017 and the actuarial loss from remeasurement upon settlement which was impacted by a decrease in the discount rate at June 30, 2017 compared to the December 31, 2016 measurement date.

⁽²⁾ Noncurrent liability recognized within pension and postretirement liabilities in the accompanying consolidated balance sheet at June 30, 2017.

Based upon current actuarial information, the Company does not have a minimum cash contribution requirement to its nonunion defined benefit pension plan for 2017. The plan’s preliminary adjusted funding target attainment percentage (“AFTAP”) is projected to be 107.8% as of the January 1, 2017 valuation date. The AFTAP is determined by measurements prescribed by the Internal Revenue Code, which differ from the funding measurements for financial statement reporting purposes.

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 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 specified in the ABF NMFA, which will remain in effect through March 31, 2018. The funding obligations to the pension plans are intended to satisfy the requirements imposed by the Pension Protection Act of 2006 (the “PPA”), 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 (the “Treasury Department”) 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

20

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”). ABF Freight received an Actuarial Certification of Plan Status for the Central States Pension Plan dated March 31, 2017, in which the plan’s actuary certified that, as of January 1, 2017, the plan is in critical and declining status, as defined by the Reform Act, with the funded percentage projected to be 40% as of the January 1, 2017 valuation date. 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 previously disclosed in the Company’s 2016 Annual Report on Form 10-K, ABF Freight received a Notice of Insolvency from the Road Carriers Local 707 Pension Fund (the “707 Pension Fund”) for the plan year beginning February 1, 2016. On March 1, 2017, the Pension Benefit Guaranty Corporation (“PBGC”) announced that beginning February 1, 2017 benefits to retirees were reduced to PBGC guarantee limits for insolvent multiemployer plans. The PBGC provides financial assistance to insolvent multiemployer plans to pay retiree benefits not to exceed guaranteed limits. The 707 Pension Fund will continue to administer the fund as the PBGC provides financial assistance. Approximately 1% of ABF Freight’s total multiemployer pension contributions are made to the 707 Pension Fund. Based on currently available information, it is the Company’s understanding that ABF Freight’s benefit contribution rates to the 707 Pension Fund under the ABF NMFA will be frozen and ABF Freight will be required to continue making contributions at the frozen rate throughout and after the current ABF NMFA contract period, which extends to March 31, 2018; however, there can be no assurance in this regard.

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 2016 Annual Report on Form 10-K.

The program has no expiration date but may be terminated at any time at the Board of Directors’ discretion. Repurchases may be made using the Company’s cash reserves or other available sources. As of December 31, 2016, the Company had $37.7 million remaining under the program for repurchases of its common stock. During the six months ended June 30, 2017 the Company purchased 194,520 shares for an aggregate cost of $3.6 million, leaving $34.1 million available for repurchase of common stock under the program.

NOTE H – SHARE-BASED COMPENSATION

Stock Awards

As of June 30, 2017 and December 31, 2016, the Company had outstanding restricted stock units granted under the 2005 Ownership Incentive Plan (the “2005 Plan”). The 2005 Plan, as amended, provides for the granting of 3.1 million shares, which may be awarded as incentive and nonqualified stock options, stock appreciation rights, restricted stock, or restricted stock units (“RSUs”).

Earnings per common share	$	0.60	$	0.39	$	0.32	$	0.16

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. Outstanding stock awards of less than 0.1 million for the three and six months ended June 30, 2017 and 0.4 million for the 2016 periods, were not included in the diluted earnings per share calculation because their inclusion would have the effect of increasing earnings per share.

NOTE J – 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.

On November 3, 2016, the Company announced its plan to implement a new corporate structure which unified the Company’s sales, pricing, customer service, marketing, and capacity sourcing functions effective January 1, 2017. As previously reported in the Company’s 2016 Annual Report on Form 10‑K, the operating segments previously reported as Premium Logistics (Panther), Transportation Management (ABF Logistics), and Household Goods Moving Services (ABF Moving) were combined into a single asset‑light logistics operation reported under the ArcBest segment for the quarter and year ended December 31, 2016.

The Company has restated certain prior year operating segment data in this Quarterly Report on Form 10-Q to conform to the current year presentation. Segment revenues and expenses were adjusted to eliminate certain intercompany charges consistent with the manner in which they are reported under the new corporate structure. Certain intercompany charges among the previously reported Panther, ABF Logistics, and ABF Moving segments which were previously eliminated in

24

the “Other and eliminations” line, are now eliminated within the ArcBest segment. There was no impact on the Company’s consolidated revenues, operating expenses, operating income, or earnings per share as a result of the restatements.

The Company’s reportable operating segments are impacted by seasonal fluctuations which affect tonnage, shipment 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:

· Asset-Based, which includes the results of operations of ABF Freight System, Inc. and certain other subsidiaries. The 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 Expedite, Truckload, and Truckload-Dedicated businesses as well as its premium logistics services; international freight transportation with air, ocean, and ground service offerings; household goods moving services to consumer, commercial, and government customers; warehousing management and distribution services; and managed transportation solutions.

ArcBest segment operations are influenced by seasonal fluctuations that impact customers’ supply chains and the resulting demand for expedite services. 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, may impact quarterly business levels. Expedite shipments of the ArcBest segment may decline during winter months because of post-holiday slowdowns but 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. The household goods 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. Shipment volumes of the ArcBest segment’s Truckload-Dedicated service offering, which was acquired in September 2016, are typically highest in the third and fourth calendar quarters of each year. Seasonal fluctuations are less apparent in the operating results of the Truckload and Truckload-Dedicated services of the ArcBest segment than in the industry as a whole because of business growth, including acquisitions, in this service offering of the segment.

· 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.

Emergency roadside service events of the FleetNet segment are favorably impacted by adverse 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 K – RESTRUCTURING CHARGES

On November 3, 2016, the Company announced its plan to implement a new corporate structure to better serve its customers. The new corporate structure unified the Company’s sales, pricing, customer service, marketing, and capacity sourcing functions effective January 1, 2017, and allows the Company to operate as one logistics provider under the ArcBest brand. As a result of the restructuring, the Company recorded $0.4 million and $2.0 million of restructuring charges in operating expenses during the three and six months ended June 30, 2017, respectively, primarily for employee-related costs.

The Company estimates it will incur restructuring charges of approximately $1.0 million during the remainder of 2017 primarily for employee-related costs associated with the plan announced during 2016.

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 62 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, 2017 and December 31, 2016, 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 $0.5 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 CONDITIONAND RESULTS OF OPERATIONS

General

ArcBest Corporation® (together with its subsidiaries, the “Company,” “we,” “us,” and “our”) provides a comprehensive suite of freight transportation services and integrated logistics solutions. On November 3, 2016, we announced our plan to implement a new corporate structure that unified our sales, pricing, customer service, marketing, and capacity sourcing functions effective January 1, 2017, and allows us to operate as one logistics provider under the ArcBest brand. 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.

Our operations are conducted through our three reportable operating segments: Asset-Based, which consists of ABF Freight System, Inc. and certain other subsidiaries; ArcBest, our asset-light logistics operation; and FleetNet. The ArcBest and the FleetNet reportable segments combined represent our Asset-Light operations. We have restated certain prior year operating segment data in this Quarterly Report on Form 10-Q to conform to the current year presentation. There was no impact on our consolidated revenues, operating expenses, operating income, or earnings per share as a result of the restatements. See additional descriptions of our segments and the restatements made to certain prior year operating segment data in Note J to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10‑Q.

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 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, 2016. Our 2016 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.

Our consolidated revenues, which totaled $720.4 million and $1,371.5 million for the three- and six-month periods ended June 30, 2017, respectively, increased 6.5% and 5.7% compared to the same prior-year periods. The year-over-year increase in consolidated revenues reflect a 5.8% increase in our Asset-Based revenues for both the three- and six-month periods ended June 30, 2017 and an 8.3% and 6.1% increase in revenues of our Asset-Light operations, which represent the combined operations of our ArcBest and FleetNet segments, for the respective periods. Our Asset-Based revenues reflect increased revenue per hundredweight including fuel surcharges and changes in freight profile effects, partially offset by slight declines in total tonnage for the three months and six months ended June 30, 2017. Asset-Light revenue growth was primarily due to incremental revenues from the September 2016 acquisition of Logistics & Distribution Services, LLC (“LDS”) and an increase in ArcBest Expedite revenues on higher business volumes, partially offset by a decline in FleetNet segment revenues due to lower service event volume. On a combined basis, the Asset-Light operating segments generated approximately 29% of our total revenues before other revenues and intercompany eliminations for the three and six months ended June 30, 2017.

Consolidated operating income for the three and six months ended June 30, 2017 increased compared to the same prior-year periods, with each reportable operating segment experiencing year-over-year operating income improvements. The increase in our consolidated operating results for the three and six months ended June 30, 2017, compared to the same prior-year periods, was primarily due to higher revenues, cost management, and favorable results from yield improvement initiatives. Consolidated operating income was impacted by pension settlement expense and restructuring charges related to the realignment of our organizational structure. The consolidated pre-tax pension settlement charge recognized for the nonunion defined benefit pension plan for the three and six months ended June 30, 2017 and 2016 was $0.7 million and $2.7 million, respectively, compared to $0.6 million and $1.5 million for the same respective periods of 2016. These charges related to lump-sum benefit distributions and, for the six months ended June 30, 2017, an annuity contract purchase made by the plan in first quarter 2017. We expect to continue to recognize pre-tax pension settlement expense related to the nonunion defined benefit pension plan estimated to approximate $1.0 million per quarter; however, the amount of quarterly pension settlement expense will fluctuate based on the amount of lump-sum benefit distributions paid to participants, actual returns on plan assets, and changes in the discount rate used to remeasure the projected benefit obligation of the plan upon settlement. Consolidated operating income for the three and six months ended June 30, 2017 was impacted by restructuring charges of $0.4 million and $2.0 million (pre-tax), of which $0.3 million and $0.9 million were included in the “Other and eliminations” line of consolidated operating income, respectively. “Other and eliminations” also includes personnel and technology expenses related to investments in improving the ArcBest experience and solutions for our customers to provide an improved platform for revenue growth and to enhance our ability to offer

30

our comprehensive transportation and logistics services across multiple operating segments. As a result of these ongoing investments and other corporate costs, we expect the loss reported in “Other and eliminations” to be approximately $4.0 million for third quarter 2017.

In addition to the above items, consolidated net income and earnings per share were impacted by income from changes in the cash surrender value of variable life insurance policies, which is reported below the operating income line in the consolidated statements of operations. A portion of these 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 $0.04 to diluted earnings per share for the three and six months ended June 30, 2017, respectively, compared to $0.02 and $0.03 per share in the same respective periods of 2016.

The year-over-year comparisons of consolidated net income and earnings per share were also impacted by a $1.2 million tax benefit, or $0.04 and $0.05 per diluted share for the three and six months ended June 30, 2017, respectively, recognized for the vesting of share-based compensation in accordance with an amendment to ASC Topic 718, Compensation – Stock Compensation which became effective in the first quarter of 2017, as well as other changes in the effective tax rates, as 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 the 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 Amended and Restated Credit Agreement (see Financing Arrangements within the Liquidity and Capital Resources section of MD&A). 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 “Business” in Item 1 and “Risk Factors” in Item 1A of our 2016 Annual Report on Form 10‑K.

The key indicators necessary to understand the operating results of our Asset-Based segment 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”).

The Asset-Based segment represented approximately 71% of our total revenues before other revenues and intercompany eliminations for the three and six months ended June 30, 2017. As part of our corporate restructuring, effective January 1, 2017, certain nonunion sales, pricing, customer service, marketing, and capacity sourcing employees were transferred to our corporate shared services departments (reported in “Other and eliminations”), which increased the percentage of union employees within the Asset-Based segment. As of June 2017, approximately 83% of Asset-Based employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which extends through March 31, 2018. The ABF NMFA included a 7% wage rate reduction effective on the November 3, 2013 implementation date, followed by wage rate increases of 2% on July 1 in each of the next three years, which began in 2014, and a 2.5% increase on July 1, 2017; a one-week reduction in annual compensated vacation effective for employee anniversary dates on or after April 1, 2013; the option to expand the use of purchased transportation; and increased flexibility in labor work rules. The ABF NMFA and the related supplemental agreements provide for continued contributions to various multiemployer health, welfare, and pension plans maintained for the benefit of Asset-Based employees who are members of the IBT. The estimated net effect of the November 3, 2013 wage rate reduction and the benefit rate increase which was applied retroactively to August 1, 2013 was an initial reduction of approximately 4% to the combined total contractual wage and benefit rate under the ABF NMFA. Following the initial reduction, the combined contractual wage and benefit contribution rate under the ABF NMFA is estimated to increase approximately 2.5% on a compounded annual basis throughout the contract period which extends through March 31, 2018.

Tonnage

The level of tonnage managed by the Asset-Based segment is directly affected by industrial production and manufacturing, distribution, residential and commercial construction, consumer spending, primarily in the North American economy, and capacity in the trucking industry. Operating results are affected by economic cycles, customers’ business cycles, and changes in customers’ business practices. The Asset-Based segment actively competes for freight business based primarily on price, service, and availability of flexible shipping options to customers. The Asset-Based segment seeks to offer value through identifying specific customer needs, then providing operational flexibility and seamless access to its services and those of our Asset-Light operations in order to respond with customized solutions.

Pricing

The industry pricing environment, another key factor to our Asset-Based results, influences the ability to obtain appropriate margins and price increases on customer accounts. Generally, freight is rated by a class system, which is established by the National Motor Freight Traffic Association, Inc. Light, bulky freight typically has a higher class and is priced at a higher revenue per hundredweight than dense, heavy freight. Changes in the rated class and packaging of the freight, along with changes in other freight profile factors such as average shipment size, average length of haul, freight density, and customer and geographic mix, can affect the average billed revenue per hundredweight measure. Changes in the rated class

32

and packaging of the freight, along with changes in other freight profile factors such as average shipment size, average length of haul, freight density, and customer and geographic mix, can affect the average billed revenue per hundredweight measure.

Approximately 30% of 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 70% of 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. The majority of the business that is subject to negotiated pricing arrangements is associated with larger customer accounts with annually negotiated pricing arrangements, and the remaining business is priced on an individual shipment basis considering each shipment’s unique profile, value provided to the customer, and current market conditions. Since pricing is established individually by account, the Asset-Based segment focuses on individual account profitability rather than a single measure of billed revenue per hundredweight when considering customer account or market evaluations. This is due to the difficulty of quantifying, with sufficient accuracy, the impact of changes in freight profile characteristics, which is necessary in estimating true price changes.

As announced on June 30, 2017, we began applying space-based pricing on shipments subject to LTL tariffs effective August 1, 2017 to better reflect freight shipping trends that have evolved over the last several years. These trends include the overall growth and ongoing profile shift of bulkier shipments across the entire supply chain, the acceleration in e-commerce, and the unique requirements of many shipping and logistics solutions. An increasing percentage of freight is taking up more space in trailers without a corresponding increase in weight, as evidenced by our Asset-Based shipment growth exceeding the change in tonnage levels in recent periods.

Space-based pricing involves the use of freight dimensions (length, width, and height) to determine applicable cubic minimum charges (“CMC”) that will supplement weight-based metrics when appropriate. Traditional LTL pricing is generally weight-based, while our linehaul costs are generally space-based (i.e., costs are impacted by the volume of space required for each shipment). Management believes space-based pricing will better align our pricing mechanisms with the metrics which affect our costs to ship the freight. We seek to provide logistics solutions to our customers’ business and the unique shipment characteristics of their various products and commodities, and we believe that we are particularly experienced in handling complicated freight. The CMC is an additional pricing mechanism to better capture the value we provide in transporting these shipments. Customer acceptance of the CMC pricing mechanism is difficult to ascertain. Management cannot predict, with reasonable certainty, the changes in business levels and the impact on the total revenue per hundredweight measure due to the implementation of the CMC mechanism.

Fuel

The transportation industry is dependent upon the availability of adequate fuel supplies. The Asset-Based segment charges a fuel surcharge which is based on the index of national on-highway average diesel fuel prices published weekly by the U.S. Department of Energy. Although revenues from fuel surcharges generally more than offset direct diesel fuel costs, other operating costs have been, and may continue to be, impacted by fluctuating fuel prices. The total impact of energy prices on other nonfuel-related expenses is difficult to ascertain. Management cannot predict, with reasonable certainty, future fuel price fluctuations, the impact of energy prices on other cost elements, recoverability of fuel costs through fuel surcharges, and the effect of fuel surcharges on the overall rate structure or the total price that the segment will receive from its customers. While the fuel surcharge is one of several components in the overall rate structure, the actual rate paid by customers is governed by market forces and the overall value of services provided to the customer.

During periods of changing diesel fuel prices, the fuel surcharge and associated direct diesel fuel costs also vary by different degrees. Depending upon the rates of these changes and the impact on costs in other fuel- and energy-related areas, operating margins could be impacted. Fuel prices have fluctuated significantly in recent years. Whether fuel prices fluctuate or remain constant, operating results may be adversely affected if competitive pressures limit our ability to recover fuel surcharges. Throughout the first six months of 2017, the fuel surcharge mechanism generally continued to have market acceptance among customers; however, certain nonstandard pricing arrangements have limited the amount of fuel surcharge recovered. The negative impact on operating margins of capped fuel surcharge revenue during periods of increasing fuel costs is more evident when fuel prices remain above the maximum levels recovered through the fuel surcharge mechanism on certain accounts.

33

In periods of declining fuel prices, fuel surcharge percentages also decrease, which negatively impacts the total billed revenue per hundredweight measure and, consequently, revenues, and the revenue decline may be disproportionate to our fuel costs. To better align fuel surcharges to fuel- and energy-related expenses and provide more stability to account profitability as fuel prices change, we may, from time to time, revise our standard fuel surcharge program which impacts approximately 35% of Asset-Based shipments and primarily affects noncontractual customers. The year-over-year Asset-Based revenue comparisons for the three and six months ended June 30, 2017 were impacted by higher fuel surcharge revenue due to an increase in the nominal fuel surcharge rate, while total fuel costs were also higher. The segment’s operating results will continue to be impacted by further changes in fuel prices and the related fuel surcharges.

Labor Costs

Our Asset-Based labor costs, including retirement and healthcare benefits for contractual employees that are provided by a number of multiemployer plans, are impacted by contractual obligations under the ABF NMFA and other related supplemental agreements. Salaries, wages, and benefits of the Asset-Based segment amounted to 61.1% and 63.2% of revenue for the three and six months ended June 30, 2017, respectively, compared to 62.3% and 64.8% for the same respective periods of 2016. The year-over-year decreases as a percentage of revenue were influenced by the effect of higher revenues, including fuel surcharges, as a portion of operating costs are fixed in nature and decrease as a percent of revenue with increases in revenue levels.

ABF Freight operates in a highly competitive industry which consists predominantly of nonunion motor carriers. Nonunion competitors have a lower fringe benefit cost structure and less stringent labor work rules, and certain carriers also have lower wage rates for their freight-handling and driving personnel. Wage and benefit concessions granted to certain union competitors also allow for a lower cost structure. ABF Freight has continued to address with the IBT the effect of the segment’s wage and benefit cost structure on its operating results.

The combined effect of cost reductions under the ABF NMFA, lower cost increases throughout the contract period, and increased flexibility in labor work rules are important factors in bringing ABF Freight’s labor cost structure closer in line with that of its competitors; however, under its collective bargaining agreement, ABF Freight continues to pay some of the highest benefit contribution rates in the industry. These rates include contributions to multiemployer plans, a portion of which are used to fund benefits for individuals who were never employed by ABF Freight. Information provided by a large multiemployer pension plan to which ABF Freight contributes indicates that approximately 50% of the plan’s benefit payments are made to retirees of companies that are no longer contributing employers to that plan. In consideration of the impact of high multiemployer pension contribution rates, certain funds have not increased ABF Freight’s pension contribution rate for the annual contribution period which began August 1, 2016. Rate freezes for the annual contribution period which began August 1, 2016 impacted multiemployer pension plans to which ABF Freight made approximately 65% of its total multiemployer pension contributions for the year ended December 31, 2016. Including the effect of these rate freezes, the average health, welfare, and pension benefit contribution rate increased approximately 2.3% effective primarily on August 1, 2016, and ABF Freight currently estimates the average health, welfare, and pension benefit contribution rate increase effective primarily on August 1, 2017 will be approximately 3.0%. Effective July 1, 2017, the ABF NMFA contractual wage rate increased 2.5%.

The Multiemployer Pension Reform Act of 2014 (the “Reform Act”), which was included in the Consolidated and Further Continuing Appropriations Act of 2015, includes provisions to address the funding of multiemployer pension plans in critical and declining status, including certain of those in which ABF Freight participates. 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 (the “Treasury Department”) for the suspension of certain benefits.

In September 2015, the Central States, Southeast and Southwest Areas Pension Plan (the “Central States Pension Plan”) filed an application with the Treasury Department seeking approval under the Reform Act for a pension rescue plan, which included benefit reductions for participants of the Central States Pension Plan in an attempt to avoid the insolvency of the plan that otherwise is projected by the plan to occur. In May 2016, the Treasury Department denied the Central States Pension Plan’s proposed rescue plan. The trustees of the Central States Pension Plan subsequently announced that a new rescue plan would not be submitted and stated that it is not possible to develop and implement a new rescue plan that complies with the final Reform Act regulations issued by the Treasury Department in April 2016. Although the future of

34

the Central States Pension Plan is impacted by a number of factors, without legislative action, the plan is currently projected to become insolvent within 10 years or less. ABF Freight’s current collective bargaining agreement with the IBT provides for contributions to the Central States Pension Plan through March 31, 2018, and it is our understanding that ABF Freight’s benefit contribution rate is not expected to increase during this period (though there are no guarantees). ABF Freight’s contribution rates are made in accordance with its collective bargaining agreements with the IBT and other related supplemental agreements. In consideration of high multiemployer plan contribution rates, several of the plans in addition to Central States Pension Plan have frozen contribution rates at current levels under ABF Freight’s current collective bargaining agreement. Future contribution rates will be determined through the negotiation process for contract periods following the term of the current collective bargaining agreement. The Asset-Based segment pays some of the highest benefit contribution rates in the industry and continues to address the effect of the segment’s wage and benefit cost structure on its operating results in discussions with the IBT.

As previously disclosed in our 2016 Annual Report on Form 10-K, ABF Freight received a Notice of Insolvency from the Road Carriers Local 707 Pension Fund (the “707 Pension Fund”) for the plan year beginning February 1, 2016. On March 1, 2017, the Pension Benefit Guaranty Corporation (“PBGC”) announced that beginning February 1, 2017 benefits to retirees were reduced to PBGC guarantee limits for insolvent multiemployer plans. The PBGC provides financial assistance to insolvent multiemployer plans to pay retiree benefits not to exceed guaranteed limits. The 707 Pension Fund will continue to administer the fund as the PBGC provides financial assistance. Approximately 1% of ABF Freight’s total multiemployer pension contributions are made to the 707 Pension Fund. Based on currently available information, it is our understanding that ABF Freight’s benefit contribution rates to the 707 Pension Fund under the ABF NMFA will be frozen and ABF Freight will be required to continue making contributions at the frozen rate throughout and after the current ABF NMFA contract period, which extends to March 31, 2018; however, there can be no assurance in this regard.

Some employer companies that participate in multiemployer plans, in which ABF Freight also participates, have received proposals from, and entered into transition agreements with, certain multiemployer plans to restructure future plan contributions to be more in line with benefit levels. These transition agreements, which require mutual agreement of numerous elements between the multiemployer plan and the contributing employer, may also result in recognition of significant withdrawal liabilities. We monitor and evaluate any such proposals we receive, including the potential economic impact to our business. At the current time, there are no proposals that have been provided to ABF Freight that management considers acceptable.

⁽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 the Asset-Based segment’s 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, 2017 totaled $514.5 million and $978.9 million, respectively, compared to $486.3 million and $925.3 million, respectively, for the same periods of 2016. Billed revenue (as described in footnote (1) to the key operating statistics table above) increased 6.2% and 5.9% on a per-day basis for the three and six months ended June 30, 2017, respectively, compared to the same prior-year period. The increases in billed revenue reflect a 6.1% and 6.2% increase in total billed revenue per hundredweight, including fuel surcharges, for the three and six months ended June 30, 2017, respectively, and tonnage per day which was relatively flat for the three-month period and decreased 0.3% for the six-month period, compared to the same periods of 2016. The number of workdays was lower by one-half of a day in the second quarter 2017 versus the prior year quarter.

The increase in total billed revenue per hundredweight benefited from yield improvement initiatives, including general rate increases and contract renewals; freight profile effects; and higher fuel surcharge revenues associated with increased fuel prices during the three- and six-month periods ended June 30, 2017, compared to the same periods of 2016.

The Asset-Based segment implemented nominal general rate increases on its LTL base rate tariffs of 4.9% and 5.25% effective May 22, 2017 and August 29, 2016, respectively, although the rate changes vary by lane and shipment characteristics. Prices on accounts subject to deferred pricing agreements and annually negotiated contracts which were renewed during the period increased approximately 3.5% and 3.7% for the three and six months ended June 30, 2017, respectively.

Compared to the same prior-year period, the average nominal fuel surcharge rate for the three and six months ended June 30, 2017 increased approximately 160 basis points and 220 basis points, respectively, from the level of the same respective period of 2016. Excluding changes in fuel surcharges, average pricing on the Asset-Based segment’s LTL business for the three and six months ended June 30, 2017 had mid-single-digit percentage increases when compared to the same prior-year periods.

36

Tonnage per day for the three and six months ended June 30, 2017, increased 0.1% and declined 0.3%, respectively, compared to the same periods of 2016. Both comparison periods reflect an increase in LTL-rated tonnage and a decline in volume-quoted, truckload-rated tonnage levels. The lower volume-quoted truckload-rated tonnage was due to purposeful management of equipment capacity to adequately serve our customers’ LTL requirements and fewer of these spot-market shipments required to reposition linehaul equipment. Average weight per shipment declined 4.1% and 5.1% for the three- and six-month period ended June 30, 2017, respectively, compared to the same prior year period, while daily shipment counts increased 4.4% and 5.0%, respectively. Lower weight per shipment reflects a combination of factors, including: the impact of reduced truckload-rated tonnage, growth in e-commerce-related shipments which generally have smaller average shipment sizes; an increase in bulkier cube-dominant shipments across the supply chain; and market capacity which allows customers to use alternative truckload carriers for some large-sized shipments.

Asset-Based Revenues — July 2017

Asset-Based billed revenues for the month of July 2017 increased approximately 3% from July 2016 on a per-day basis, reflecting an increase in total billed revenue per hundredweight of approximately 6%, which includes higher fuel surcharges, partially offset by a 3% decrease in average daily total tonnage for July 2017 compared to July 2016 levels. The Asset-Based segment handled fewer spot volume truckload-rated shipments during July 2017 versus the same prior-year period, which resulted in a lower weight per shipment. Due to an increase in LTL-rated shipments, total shipments per day increased approximately 3% in July 2017. 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. Furthermore, some customers may not be receptive to our space-based pricing initiatives, which could result in a loss of business.

Asset-Based Operating Income

The Asset-Based segment operating ratio for the three- and six-month period ended June 30, 2017 improved by 0.7 and 0.3 percentage points, respectively, over the same prior-year periods. The Asset-Based segment generated operating income of $22.2 million and $12.1 million for the three and six months ended June 30, 2017, respectively, compared to operating income of $17.4 million and $8.4 million in the same periods of 2016. The operating income comparisons reflect a $0.1 million and $0.8 million increase in nonunion pension settlement expense for the three and six months ended June 30, 2017, respectively, and $0.2 million of restructuring charges associated with our corporate realignment during the six months ended June 30, 2017. Gain on sale of property and equipment was $2.2 million and $1.8 million higher in the three- and six-month period ended June 30, 2016, respectively, due to a second quarter 2016 gain on the sale of real estate. Further improving the Asset-Based operating ratio is dependent upon: managing the segment’s cost structure (as discussed in Labor Costs of the Asset-Based Segment Overview of Results of Operations) and securing price increases to cover contractual wage and benefit rate increases, changes in freight profile of shipments, costs of maintaining customer service levels, and other inflationary increases in cost elements.

The trend we have experienced in recent quarters of growth in shipment levels at a lower average weight per shipment continued in second quarter 2017. Since revenue for each shipment is typically determined by applying a price (which considers freight profile characteristics) to the weight of the shipment, this trend has had a negative impact on revenue per shipment while still requiring operating resources (including labor and, in certain markets, local purchased transportation agents) to handle higher numbers of shipments. For the three and six months ended June 30, 2017, shipments per day increased 4.4% and 5.0%, respectively, while daily tonnage improved slightly in second quarter and declined 0.3% for the six months ended June 30, 2017, compared to the same periods of 2016, leading to lower weight per shipment and, consequently, lower revenue per shipment. As previously discussed in the Asset-Based Segment Overview section of Results of Operations, we began applying space-based pricing on certain Asset-Based shipments effective August 1, 2017, to supplement traditional weight-based LTL pricing to more appropriately reflect the cost of our services related to recent trends of lighter, bulkier freight in our network. The Asset-Based segment operating ratio was also impacted by changes in the operating expenses discussed in the following paragraphs.

Asset-Based Operating Expenses

Labor costs, which are reported in operating expenses as salaries, wages, and benefits, amounted to 61.1% and 63.2% of Asset-Based segment revenues for the three- and six- month period ended June 30, 2017, respectively, compared to 62.3% and 64.8% for the same respective periods of 2016. Salaries, wages, and benefits costs increased $11.0 million and $19.7 million for the three and six months ended June 30, 2017, respectively, compared to the same prior-year periods.

37

The year-over-year increases in labor costs were impacted by increases in contractual wage and benefit contribution rates under the ABF NMFA. The contractual wage rate increased 2.0% effective July 1, 2016, and the average health, welfare, and pension benefit contribution rate increased approximately 2.3% effective primarily on August 1, 2016, including the effect of the multiemployer pension plan rate freezes previously discussed in the Asset-Based Segment Overview section of Results of Operations.

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. Management believes that this service emphasis provides for the opportunity to generate improved yields and business levels. Returning productivity to historical levels is an important priority for the management team in order to reduce costs. The decline in shipments per DSY hour of 2.0% and 0.7% for the three and six months ended June 30, 2017, respectively, compared to the same prior-year period, was primarily due to the increase in lighter but bulkier shipments. Lower weight per shipment contributed to the 6.0% and 5.7% decrease in pounds per DSY hour during the three- and six-month period ended June 30, 2017, respectively, compared to the same periods of 2016. The 0.2% decrease in pounds per mile for second quarter 2017, compared to second quarter 2016, reflects the lower weight per shipment and a higher average length of haul. The 0.2% increase in pounds per mile for the six months ended June 30, 2017, reflects a combination of increased utilization of purchased transportation, including rail services, and more efficient linehaul operations compared to the same prior-year period.

Fuel, supplies, and expenses as a percentage of revenue increased 0.5 percentage points for the six months ended June 30, 2017, compared to the same prior-year period, primarily due to an increase in the Asset-Based segment’s average fuel price per gallon (excluding taxes) of approximately 26.0%. The increase in fuel, supplies, and expenses was partially offset by fewer road miles driven during the 2017 period.

Rents and purchased transportation as a percentage of revenue increased 0.6 and 0.7 percentage points for the three and six months ended June 30, 2017, respectively, compared to the same prior-year periods. The increase in these costs was primarily related to an increase in rail miles of approximately 22.7% and 18.7% for the three and six months ended June 30, 2017, respectively, higher utilization of local purchased transportation agents, and higher fuel surcharges associated with these purchased transportation services which were required to handle higher shipment levels. Rental expense for revenue equipment also increased for the three and six month periods ended June 30, 2017, compared to the same prior year periods, to handle the increased shipment levels.

Gain (loss) on sale of property and equipment as a percentage of revenue increased 0.5 and 0.2 percentage points for the three and six months ended June 30, 2017, respectively, compared to the same periods of 2016, primarily due to a $2.1 million gain on the sale of real estate in second quarter 2016.

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 they encounter. Our corporate structure unifies our sales, pricing, customer service, marketing, and capacity sourcing functions to better serve our customers through delivery of integrated logistics solutions.

38

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 “Business” in Item 1 and “Risk Factors” in Item 1A of our 2016 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;

· net revenue for the ArcBest segment, which is defined as revenues less purchased transportation operating expense; and

· management of operating costs.

As previously disclosed within the General section of MD&A, we have restated certain prior year operating segment data in this Quarterly Report on Form 10-Q to conform to the current year presentation. See descriptions of the Asset-Light operating segments and discussion of the restated prior year operating segment data in Note J to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10‑Q.

For the three and six months ended June 30, 2017, the combined revenues of our Asset-Light operations totaled $212.4 million and $405.5 million, respectively, compared to combined revenues of $196.1 million and $382.1 million, respectively, for the same periods of 2016. The combined revenues of our Asset-Light operating segments generated approximately 29% of our total revenues before other revenues and intercompany eliminations for the three and six months ended June 30, 2017 and 2016.

ArcBest Segment

The following table provides a comparison of key operating statics for the ArcBest Segment.

	Year Over Year % Change
	Three Months Ended		Six Months Ended
	June 30, 2017		June 30, 2017
Expedite(1)
Revenue / Shipment		14.3%		12.2%
Shipments / Day		4.0%		1.1%
Truckload and Truckload - Dedicated(2)
Revenue / Shipment		6.8%		4.7%
Shipments / Day		17.7%		17.1%

⁽¹⁾ Expedite primarily represents the expedited operations which were previously reported in the Premium Logistics (Panther) segment.

⁽²⁾ Truckload represents the brokerage operations and Truckload – Dedicated represents the dedicated operations of LDS, both of which were previously reported in the Transportation Management (ABF Logistics) segment. Comparisons are impacted by the operations of LDS, which was acquired in September 2016.

The ArcBest segment revenues totaled $175.9 million and $328.8 million for the three and six months ended June 30, 2017, respectively, compared to $154.3 million and $296.7 million, respectively, for the same prior-year periods. The 14.0% and 10.8% increase in revenues for the three and six months ended June 30, 2017, respectively, compared to the same prior-year period, primarily reflects incremental revenues from Truckload-Dedicated, which represents the acquired operations of LDS, and an increase in Expedite revenues due to increases in shipment levels and revenue per shipment. The year-over-year increase in ArcBest segment revenues was partially offset by lower Truckload and Moving revenues due to a decrease in shipment levels, primarily reflecting lower demand for our truckload brokerage and household goods moving services. The decrease in Moving revenues for the three and six months ended June 30, 2017 was also impacted by the December 2016 divesture of certain subsidiaries associated with the segment’s household goods moving services.

39

ArcBest segment net revenue, which is a measure of revenues less costs of purchased transportation, increased 11.4% and 6.5% for the three and six months ended June 30, 2017, respectively, compared to the same periods of 2016, due to higher Expedite net revenue and the incremental net revenue from LDS. ArcBest’s net revenue margin was 20.8% and 20.5% for the three and six months ended June 30, 2017, respectively, versus 21.3% and 21.4%, respectively, for the same prior year periods, with the year-over-year declines reflecting the increased cost of purchased transportation outpacing improvements in customer rates. Purchased transportation costs moved higher in 2017 as capacity in the spot market tightened versus the prior year.

Operating income increased $3.6 million and $4.5 million for the three and six months ended June 30, 2017, respectively, compared to the same periods of 2016. The ArcBest segment profit improvement was negatively impacted by restructuring charges of $0.1 million and $0.9 million for the three and six months ended June 30, 2017, respectively, related to realignments under our enhanced marketing approach. (See Note J and Note K to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q for discussion of our corporate restructuring.) The profit improvement primarily reflects increased net revenues combined with lower salaries, wages, and benefits due to alignment of the segment’s cost structure resulting from the realignments under our enhanced marketing approach. 

FleetNet Segment

FleetNet’s revenues totaled $36.5 million and $76.7 million for the three and six months ended June 30, 2017, respectively, compared to $41.8 million and $85.3 million for the same periods of 2016. The 12.6% and 10.1% year-over-year decrease in revenues for the three- and six-month period ended June 30, 2017, respectively, was primarily due to lower roadside service event activity, partially offset by an increase in preventative maintenance service events and improved roadside event pricing.

FleetNet’s operating income improved to $0.7 million and $1.7 million for the three and six months ended June 30, 2017, respectively, from $0.6 million and $1.6 million, respectively, in the same prior-year periods. The year-over-year improvements in operating income for the 2017 periods, despite lower revenues, reflect labor efficiencies and alignment of the segment’s cost structure to business levels.

Asset-Light 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 EBITDA as a key measure of performance and for business planning. The measure is particularly meaningful for analysis, because it excludes amortization of acquired intangibles and software of the Asset-Light businesses, 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⁾ Certain restatements have been made to the prior year’s operating segment data to conform to the current year presentation, reflecting the realignment of our corporate structure.

⁽³⁾ For the ArcBest segment, depreciation and amortization includes amortization of acquired intangibles of $1.1 million and $2.3 million for the three and six months ended June 30, 2017, respectively, compared to $1.0 million and $2.0 million for the same respective prior-year periods, and amortization of acquired software of $0.8 million and $1.7 million for the three and six months ended June 30, 2017, respectively, compared to $1.1 million and $2.3 million for the same respective prior-year periods.

⁽⁴⁾ Restructuring costs relate to the realignment of our corporate structure.

Seasonality

Our operations are impacted by seasonal fluctuations which affect tonnage, shipment levels, and demand for our services and, consequently, revenues and operating results. Freight shipments and operating costs of our Asset-Based and ArcBest segments 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.

Expedite shipments of the ArcBest segment may decline during winter months because of post-holiday slowdowns but 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. The household goods 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. Shipment volumes of the ArcBest segment’s Truckload-Dedicated service offering, which was acquired in September 2016, are typically highest in the third and fourth calendar quarters of each year. Seasonal fluctuations are less apparent in the operating results of the Truckload and Truckload-Dedicated services of the ArcBest segment than in the industry as a whole because of business growth, including acquisitions, in this service offering of the segment.

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

41

Effects of Inflation

Generally, inflationary increases in labor and fuel costs as they relate to our Asset-Based operations have historically been mostly offset through price increases and fuel surcharges. In periods of increasing fuel prices, the effect of higher associated fuel surcharges on the overall price to the customer influences our ability to obtain increases in base freight rates. In addition, certain nonstandard arrangements with some of our customers have limited the amount of fuel surcharge recovered. The timing and extent of base price increases on our Asset-Based revenues may not correspond with contractual increases in wage rates and other inflationary increases in cost elements and, as a result, could adversely impact our operating results.

In addition, partly as a result of inflationary pressures, our revenue equipment (tractors and trailers) have been and will very likely continue to be replaced at higher per unit costs, which could result in higher depreciation charges on a per-unit basis; however, in recent periods, improved mileage and lower maintenance costs on newer equipment have partially offset increases in depreciation expense. We consider these costs in setting our pricing policies, although the overall freight rate structure is governed by market forces based on value provided to the customer. The Asset-Based segment’s ability to fully offset inflationary and contractual cost increases can be challenging during periods of recessionary and uncertain economic conditions.

Generally, inflationary increases in labor and operating costs regarding our Asset-Light operations have historically been offset through price increases. The pricing environment, however, generally becomes more competitive during economic downturns, which may, as it has in the past, affect the ability to obtain price increases from customers.

In addition to general effects of inflation, the motor carrier freight transportation industry faces rising costs related to compliance with government regulations on safety, equipment design and maintenance, driver utilization, emissions, and fuel economy.

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 terminals 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 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 and availability of our information systems, including communications and data processing systems and proprietary software programs that are integral to the efficient operation of our business. Cybersecurity attacks and cyber incidents that impact the availability, reliability, speed, accuracy, or other proper functioning of these systems or that result in confidential data being compromised could have a significant impact on our operations. We utilize certain software applications provided by third parties, or 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. 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

42

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 cyber incident, including denial of service, system failure, security breach, intentional or inadvertent acts by employees, 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 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 have made and continue to make significant financial investments in technologies and processes to mitigate these 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, short-term investments, and restricted cash were as follows:

	June 30		December 31
	2017		2016
	(in thousands)
Cash and cash equivalents(1)	$	102,569	$	114,280
Short-term investments, primarily FDIC-insured certificates of deposit		54,148		56,838
Total unrestricted		156,717		171,118
Restricted cash(2)		—		962
Total(3)	$	156,717	$	172,080

⁽¹⁾ Cash equivalents consist of money market funds and variable rate demand notes.

⁽²⁾ Restricted cash represents cash deposits pledged as collateral for outstanding letters of credit in support of workers’ compensation and third-party casualty claims liabilities (see the Financing Arrangements in this section of MD&A).

⁽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. At  June 30, 2017 and December 31, 2016 cash and cash equivalents totaling $46.0 million and $39.9 million, respectively, were not FDIC insured.

Unrestricted cash, cash equivalents, and short-term investments decreased $14.4 million from December 31, 2016 to June 30, 2017. During the six-month period ended June 30, 2017, cash provided by operations of $51.3 million, $10.0 million of borrowings under the accounts receivable securitization program, and cash on hand was used to repay $34.9 million of notes payable; fund $24.4 million of capital expenditures (and an additional $38.6 million of certain Asset-Based revenue equipment purchases were financed with notes payable), net of proceeds from asset sales; pay dividends of $4.1 million on common stock; and purchase $3.6 million of treasury stock.

43

Cash provided by operating activities during the six months ended June 30, 2017 was $2.4 million below the same prior-year period, primarily due to changes in taxes and working capital, partially offset by improved operating results. A contribution of $13.4 million was made to the nonunion defined benefit pension plan during the six months ended June 30, 2016. Cash provided by operating activities for the six months ended June 30, 2017 included state and foreign income tax payments, net of refunds of federal and state income taxes, of $0.3 million, compared to refunds of federal and state income taxes, net of state and foreign income tax payments, of $8.6 million for the six months ended June 30, 2016.

Unrestricted cash, cash equivalents, and short-term investments decreased $10.3 million from December 31, 2015 to June 30, 2016. During the six-month period ended June 30, 2016, cash provided by operations of $52.5 million and cash on hand was used to fund $19.8 million of capital expenditures net of proceeds from asset sales (and an additional $35.8 million of certain ABF Freight revenue equipment purchases were financed with notes payable); repay $22.8 million of notes payable; pay $6.5 million of book overdrafts (representing checks issued that were later funded when cleared through banks); purchase $5.1 million of treasury stock; and pay dividends of $4.2 million on common stock.

Financing Arrangements

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

Credit Facility

Under our amended and restated credit agreement (the “Amended and Restated Credit Agreement”), we have a revolving credit facility (the “Credit Facility”) which had an initial maximum credit amount of $150.0 million, including a swing line facility 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 Credit Facility allows us to request additional revolving commitments or incremental term loans thereunder up to an aggregate additional amount of $75.0 million, subject to certain additional conditions as provided in the Amended and Restated Credit Agreement. Principal payments under the Credit Facility are due upon maturity of the facility on January 2, 2020; however, borrowings may be repaid at our discretion in whole or in part at any time, without penalty, subject to required notice periods and compliance with minimum prepayment amounts. The Amended and Restated Credit Agreement includes certain conditions including limitations on incurrence of debt.

In July 2017, we amended and extended our credit agreement (the “Second Amended and Restated Credit Agreement”) to increase the initial maximum credit amount of our Credit Facility from $150.0 million to $200.0 million, including a swing line facility and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $20.0 million, and to increase the additional revolving commitments or incremental term loans we may request under the facility from $75.0 million to $100.0 million. The maturity date of the Credit Facility was extended to July 7, 2022. The covenants and conditions of the Second Amended and Restated Credit Agreement are consistent with the previously amended credit agreement.

Interest Rate Swap

We have a five-year interest rate swap agreement with a $50.0 million notional amount maturing on January 2, 2020. Under the interest rate swap agreement, we receive 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 our Credit Facility from variable-rate interest to fixed-rate interest with a per annum rate of 3.35% based on the margin of the Credit Facility as of June 30, 2017. The fair value of the interest rate swap liability of $0.3 million and $0.5 million was recorded in other long-term liabilities in the consolidated balance sheet at June 30, 2017 and December 31, 2016, respectively.

44

In June 2017, we 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. Under the swap agreement we 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 interest rate swap 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 3.49% based on the margin of the Credit Facility as of June 30, 2017. The fair value of the interest rate swap of $0.2 million was recorded in other long-term assets in the consolidated balance sheet at June 30, 2017.

Accounts Receivable Securitization Program

Our accounts receivable securitization program, which matures on April 1, 2020, provides cash proceeds of $125.0 million and has an accordion feature allowing us to request additional borrowings up to $25.0 million, subject to certain conditions. Under this program, certain of our subsidiaries continuously sell a designated pool of trade accounts receivables to a wholly owned subsidiary which, in turn, may borrow funds on a revolving basis. During 2015, we borrowed $35.0 million and in April 2017 we borrowed an additional $10.0 million under the accounts receivable securitization program to provide additional funds for investing in our subsidiaries’ capital needs and to maintain flexibility for our growth initiatives.

The accounts receivable securitization program includes a provision under which we 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 we are self-insured. The outstanding standby letters of credit reduce the availability of borrowings under the program. As of June 30, 2017, we had available borrowing capacity of $61.0 million under the accounts receivable securitization program.

Letter of Credit Agreements and Surety Bond Programs

As of June 30, 2017, we had letters of credit outstanding of $19.6 million (including $19.0 million issued under the accounts receivable securitization program). We have programs in place with multiple surety companies for the issuance of surety bonds in support of our self-insurance program. As of June 30, 2017, surety bonds outstanding related to our self-insurance program totaled $59.4 million.

Notes Payable and Capital Leases

We have financed the purchase of certain revenue equipment, other equipment, and software through promissory note arrangements, including $37.9 million and $38.6 million, primarily for revenue equipment, during the three and six months ended June 30, 2017, respectively. We intend to utilize promissory note arrangements and will consider utilizing capital lease agreements to finance future purchases of certain revenue equipment, provided such financing is available and the terms are acceptable to us.

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, certain construction costs associated with our new office and call center facility, software, certain service contracts, and other items for which amounts were not accrued in the consolidated balance sheet as of June 30, 2017. These purchase obligations totaled $103.0 million as of June 30, 2017, with $95.5 million estimated to be paid within the next year, $7.2 million estimated to be paid in the following two-year period, and $0.3 million to be paid within five years, provided that vendors complete their commitments to us. Purchase obligations for revenue equipment, other equipment, and costs associated with our new office and call center facility are included in our 2017 capital expenditure plan.

Our contractual obligations related to our notes payable, which provide financing for revenue equipment purchases, totaled $147.3 million, including interest, as of June 30, 2017, an increase of $5.2 million from December 31, 2016. The scheduled maturities of our long-term debt obligations as of June 30, 2017, including our contractual obligation to repay the $45.0 million borrowed on our accounts receivable securitization program, are disclosed in Note E 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 2016 Annual Report on Form 10‑K during the six months ended June 30, 2017. As previously disclosed in the Financing Arrangements section of Liquidity and Capital Resources, we

45

entered into our Second Amended and Restated Credit Agreement in July 2017 to increase the initial maximum credit amount of our Credit Facility from $150.0 million to $200.0 million, including a swing line facility and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $20.0 million, and to increase the additional revolving commitments or incremental term loans we may request under the facility from $75.0 million to $100.0 million. The maturity date of the Credit Facility was extended to July 7, 2022.

For 2017, our total net capital expenditures, including amounts financed, are estimated to range from $150.0 million to $165.0 million, net of asset sales. These 2017 estimated net capital expenditures include revenue equipment purchases of $96.0 million, primarily for our Asset-Based operations. Expected real estate expenditures totaling approximately $32.0 million are for expansion opportunities and completion of previously disclosed call center facilities and office buildings, a portion of which will replace leased space. The remainder of 2017 expected capital expenditures includes costs of other facility and handling equipment for our Asset-Based segment and technology investments across the enterprise. We have the flexibility to adjust planned 2017 capital expenditures as business levels dictate. Depreciation and amortization expense is estimated to be in a range of $105.0 million to $110.0 million in 2017.

Based upon current actuarial information, we do not have a minimum cash contribution requirement to our nonunion defined benefit pension plan for 2017 (see Note F to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10‑Q).

Our Asset-Based segment contributes to multiemployer health, welfare, and pension plans based generally on the time worked by its contractual employees, as specified in the collective bargaining agreement and other supporting supplemental agreements (see Note F to the Company’s consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q).

Other Liquidity Information

Cash, cash equivalents, and short-term investment totaled $156.7 million at June 30, 2017. 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 Credit Facility and accounts receivable securitization program provide available sources of liquidity with flexible borrowing and payment options. We believe these agreements will continue to 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 Second Amended and Restated 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, capital 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.

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 Second Amended and Restated Credit Agreement; and other factors. On July 25, 2017, the Company’s Board of Directors declared a dividend of $0.08 per share to stockholders of record as of August 8, 2017, payable on August 22, 2017.  

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 three months ended June 30, 2017, we purchased 194,520 shares of our common stock, leaving $34.1 million available for repurchase under the current buyback program.

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, 2017. We have interest rate swap agreements in place which are discussed in the Financing Arrangements section of Liquidity and Capital Resources.

Balance Sheet Changes

Accounts Receivable

Accounts receivable increased $22.2 million from December 31, 2016 to June 30, 2017, primarily due to higher business levels in June 2017 compared to December 2016.

Property, Plant, and Equipment, net

Property, plant and equipment, net of allowances for depreciation and amortization, increased $22.7 million from December 31, 2016 to June 30, 2017, primarily due to $66.1 million of capital expenditures, net of proceeds from asset sales, including revenue equipment purchases and amounts related to our new call center facility and office building, net of depreciation and amortization expense of $48.3 million. We financed $38.6 million of the capital expenditures, primarily for Asset-Based revenue equipment, with notes payable arrangements.

Off-Balance Sheet Arrangements

At June 30, 2017, our off-balance sheet arrangements of $168.9 million included purchase obligations, as previously discussed in the Contractual Obligations section of Liquidity and Capital Resources, and future minimum rental commitments, net of noncancelable subleases, under operating lease agreements primarily for our Asset-Based service centers.

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 34.6% and 27.1% for the three and six months ended June 30, 2017, respectively, compared to 37.5% and 37.8%, respectively, for the three and six months ended June 30, 2016. Our U.S. statutory tax rate is 35% and the average state tax rate, net of the associated federal deduction, is approximately 3%. However, various factors may cause the full-year 2017 tax rate to vary significantly from the statutory rate.

The difference between our effective tax rate and the federal statutory rate for the three and six months ended June 30, 2017 and 2016, primarily results from state income taxes, nondeductible expenses, changes in deferred tax valuation allowances, and changes in the cash surrender value of life insurance. The three- and six-month period ended June 30, 2016 reflects a benefit of 1.9% and 8.6%, respectively, related to the alternative fuel tax credit which expired December31, 2016.

In the first quarter of 2017, we adopted an amendment to ASC Topic 718, Compensation – Stock Compensation, which requires the income tax effects of awards to be recognized in the statement of operations when awards vest or are settled. As a result of applying the provisions of the amendment, the tax rate for the three and six months ended June 30, 2017 reflects a benefit of 4.8% and 10.8%, respectively. We may experience volatility in our income tax provision as a result of recording all excess tax benefits and tax deficiencies in the income statement upon settlement of awards, which is primarily during the second quarter of each year.

At June 30, 2017, we had $55.5 million of net deferred tax liabilities after valuation allowances. Valuation allowances for deferred tax assets totaled $0.1 million and $0.3 million at June 30, 2017 and December 31, 2016, respectively. We evaluated the need for a valuation allowance for deferred tax assets at June 30, 2017 by considering the future reversal of existing taxable temporary differences, future taxable income, taxable income in carryback years, and available tax planning strategies. As of June 30, 2017, deferred tax liabilities which will reverse in future years exceeded deferred tax assets.

47

Financial reporting income differs significantly from taxable income because of such items 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, 2017, the financial reporting income exceeded the income determined under income tax law. For the six months ended June 30, 2016, a loss was determined under income tax law, but we had financial reporting income.

During the six months ended June 30, 2017, we made state and foreign tax payments of $0.4 million, and received refunds of $0.1 million of federal and 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 2016 Annual Report on Form 10-K. There have been no material changes in our critical accounting policies during the six months ended June 30, 2017. 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.

The Financial Accounting Standards Board (the “FASB”) issued an accounting pronouncement related to revenue recognition (ASC Topic 606), which amends the guidance in former ASC Topic 605, Revenue Recognition. The new standard provides a single comprehensive revenue recognition model for all contracts with customers and contains principles to apply to determine the measurement of revenue and timing of when it is recognized. The standard is effective for us on January 1, 2018. We are currently in the process of contract review and documentation in preparation for adopting the revenue recognition standard. We plan to adopt this standard using the modified retrospective approach, which requires the effects of adoption to be reflected in beginning retained earnings, and we do not expect a significant impact on our consolidated financial statements.

The FASB issued ASC Topic 842, Leases, which will be effective for us on January 1, 2019. The updated accounting guidance will require many operating leases to be reflected as liabilities with associated right-of-use assets in our consolidated balance sheet. We are currently assessing the impact this update, which is required to be adopted on the modified retrospective basis, will have on our consolidated financial statements.

Management believes that there is no other new accounting guidance issued but not yet effective that will impact our critical accounting policies.

Forward-Looking Statements

Certain statements and information in this Quarterly Report on Form 10-Q may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Terms such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “foresee,” “intend,” “may,” “plan,” “predict,” “project,” “scheduled,” “should,” “would” and similar expressions and the negatives of such terms are intended to identify forward-looking statements.

Although we believe that the expectations reflected in these forward-looking statements are reasonable as and when made, we cannot provide assurance that our expectations will prove to be correct. Actual outcomes and results could materially differ from what is expressed, implied, or forecasted in these statements due to a number of factors, including, but not limited to: a failure of our information systems, including disruptions or failures of services essential to our operations or upon which our information technology platforms rely, data breach, and/or cybersecurity incidents; not achieving some or all of the expected financial and operating benefits of our corporate restructuring or incurring additional costs or operational inefficiencies as a result of the restructuring; relationships with employees,

48

including unions, and our ability to attract and retain employees; unfavorable terms of, or the inability to reach agreement on, future collective bargaining agreements or a workforce stoppage by our employees covered under ABF Freight’s collective bargaining agreement; competitive initiatives and pricing pressures; union and nonunion employee wages and benefits, including changes in required contributions to multiemployer plans; the cost, integration, and performance of any recent or future acquisitions; general economic conditions and related shifts in market demand that impact the performance and needs of industries we serve and/or limit our customers’ access to adequate financial resources; governmental regulations; environmental laws and regulations, including emissions-control regulations; the loss or reduction of business from large customers; litigation or claims asserted against us; the cost, timing, and performance of growth initiatives; the loss of key employees or the inability to execute succession planning strategies; availability and cost of reliable third-party services; our ability to secure independent owner operators and/or operational or regulatory issues related to our use of their services; default on covenants of financing arrangements and the availability and terms of future financing arrangements; timing and amount of capital expenditures; self-insurance claims and insurance premium costs; availability of fuel, the effect of volatility in fuel prices and the associated changes in fuel surcharges on securing increases in base freight rates, and the inability to collect fuel surcharges; increased prices for and decreased availability of new revenue equipment, decreases in value of used revenue equipment, and higher costs of equipment-related operating expenses such as maintenance and fuel and related taxes; potential impairment of goodwill and intangible assets; maintaining our intellectual property rights, brand, and corporate reputation; seasonal fluctuations and adverse weather conditions; regulatory, economic, and other risks arising from our international business; antiterrorism and safety measures; and other financial, operational, and legal risks and uncertainties detailed from time to time in our public filings with the Securities and Exchange Commission.

For additional information regarding known material factors that could cause our actual results to differ from our projected results, refer to “Risk Factors” in Part I, Item 1A in our 2016 Annual Report on Form 10-K.

Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date made and, other than as required by law, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As disclosed in Part II, Item 7A of the our 2016 Annual Report on Form 10-K, we are subject to interest rate risk due to variable interest rates on the borrowings under our accounts receivable securitization program, which was amended in March 2017 to provide cash proceeds of up to $125.0 million with an accordion feature allowing us to request additional borrowings up to $25.0 million, subject to certain conditions. Our accounts receivable securitization program is further described in Financing Arrangements of the Liquidity and Capital Resources section of Management’s Discussion and Analysis (“MD&A”) in Part I, Item 2 of this Quarterly Report on Form 10-Q.

In April 2017, we borrowed an additional $10.0 million under our accounts receivable securitization program. Borrowings under the facility bear interest based on LIBOR, plus a margin, and an annual facility fee, and are considered to be priced at market for debt instruments having similar terms and collateral requirements. We are required to make monthly interest payments, with remaining principal outstanding due upon the maturity of the borrowing in January 2018.

In June 2017, we entered into a forward-starting interest rate swap agreement with a $50.0 million notional amountwhich will start on January 2, 2020 upon maturity of the current interest rate swap agreement, and mature on June 30, 2022. Under the agreement, beginning in January 2020, we 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 agreement was entered in contemplation of a probable financing transaction to amend and increase borrowing capacity under the Credit Agreement.

In July 2017, we amended and extended our credit agreement (the “Second Amended and Restated Credit Agreement”) to increase the initial maximum credit amount of our Credit Facility from $150.0 million to $200.0 million, including a swing line facility and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $20.0 million, and to increase the additional revolving commitments or incremental term loans we may request under the facility from $75.0 million to $100.0 million. The maturity date of the Credit Facility was extended to July 7, 2022.

The following table reflects the contractual maturity date and projected interest rates (based on a LIBOR curve, provided by a financial institution independent of the facility, plus our margin) for the $45.0 million borrowing outstanding under the accounts receivable securitization as of June 30, 2017:

Since December 31, 2016, there have been no other significant changes in the Company’s market risks as reported in the Company’s 2016 Annual Report on Form 10-K.

ITEM 4. CONTROLS AND PROCEDURES

As of the end of the period covered by this report, an evaluation was performed with the participation of the Company’s management, including the Principal Executive Officer and Principal Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. Based on that evaluation, the Company’s management, including the Principal Executive Officer and Principal Financial Officer, concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2017.

There were no changes in the Company’s internal controls over financial reporting that occurred during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal controls over financial reporting.

ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION

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® (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, 2017. As part of our corporate restructuring (further described in “Financial Statement Presentation” within this Note), effective January 1, 2017, certain nonunion sales, pricing, customer service, marketing, and capacity sourcing employees were transferred to our corporate shared services departments (reported in “Other and eliminations”), which increased the percentage of union employees within the Asset-Based segment. As of June 2017, approximately 83% of the Asset-Based segment’s employees were covered under a collective bargaining agreement, the ABF National Master Freight Agreement (the “ABF NMFA”), with the International Brotherhood of Teamsters (the “IBT”), which extends through March 31, 2018. The ABF NMFA included a 7% wage rate reduction upon the November 3, 2013 implementation date, followed by wage rate increases of 2% on July 1 in each of the next three years, which began in 2014, and a 2.5% increase on July 1, 2017; a one-week reduction in annual compensated vacation effective for employee anniversary dates on or after April 1, 2013; the option to expand the use of purchased transportation; and increased flexibility in labor work rules. The ABF NMFA and the related supplemental agreements provide for continued contributions to various multiemployer health, welfare, and pension plans maintained for the benefit of the Asset-Based segment’s employees who are members of the IBT. The estimated net effect of the November 3, 2013 wage rate reduction and the benefit rate increase which was applied retroactively to August 1, 2013 was an initial reduction of approximately 4% to the combined total contractual wage and benefit rate under the ABF NMFA. Following the initial reduction, the combined contractual wage and benefit contribution rate under the ABF NMFA is estimated to increase approximately 2.5% on a compounded annual basis throughout the contract period which extends through March 31, 2018.

On September 2, 2016, the ArcBest segment acquired Logistics & Distribution Services, LLC (“LDS”), a private logistics and distribution company, in a transaction valued at $25.0 million (subject to post-closing adjustments), reflecting net cash consideration of $17.0 million paid at closing and an additional $8.0 million of contingent consideration to be paid over the two years following the acquisition upon the achievement of certain financial targets. As the LDS acquisition is not significant to the Company’s consolidated operating results and financial condition, pro forma financial information and the purchase price allocations of acquired assets and liabilities have not been presented. The results of the acquired operations subsequent to the acquisition date have been included in the accompanying consolidated financial statements.The Company is in the process of making a final determination of the value of acquired assets and liabilities for the LDS transaction and the provisional measurements are subject to change during the measurement period.

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 “Commission”) 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 2016 Annual Report on Form 10-K and other current filings with the Commission. In the opinion of management, all adjustments (which are of a normal and recurring nature) considered necessary for a fair presentation have been included.

Certain restatements have been made to the prior year’s operating segment data to conform to the current year presentation, reflecting the realignment of the Company’s organizational structure as announced on November 3, 2016. Under the new structure, the segments previously reported as Premium Logistics (Panther), Transportation Management (ABF Logistics), and Household Goods Moving Services (ABF Moving) are consolidated as a single Asset-Light logistics operation under ArcBest. Segment revenues and expenses were adjusted to eliminate certain intercompany charges consistent with the manner in which they are reported under the new corporate structure. Certain intercompany charges among the previously reported Panther, ABF Logistics, and ABF Moving segments which were previously eliminated in the “Other and eliminations” line, are now eliminated within the ArcBest segment. There was no impact on the Company’s consolidated revenues, operating expenses, operating income, or earnings per share as a result of the restatements.

Certain reclassifications have been made to the prior year’s consolidated financial statements to conform to the current year presentation. The insurance receivable for the amount of workers’ compensation and third-party casualty claims in excess of self-insurance retention limits, which was previously offset against the reserve included in accrued expenses, has been reclassed to other accounts receivable, resulting in an $8.7 million increase in other accounts receivable and a corresponding increase in accrued expenses in the consolidated balance sheet at December 31, 2016. Amounts totaling $18.6 million related to certain service centers of the Company’s Asset-Based operations previously recorded in leasehold improvements were reclassed to land and structures in the consolidated balance sheet at December 31, 2016. These reclassifications were previously reported in the Company’s first quarter 2017 Quarterly Report on Form 10-Q. The prior period impact of the reclassification of the insurance receivable is also reflected in the consolidated statements of cash flows for the six months ended June 30, 2016.

Other reclassifications were made to the consolidated financial statements to apply the provisions of accounting pronouncements adopted during the first quarter of 2017 related to deferred income taxes, share-based compensation, and cash flow classification (see Adopted Accounting Pronouncements within this Note). The Company’s deferred tax assets were reclassed, by jurisdiction, from current to long-term in the consolidated balance sheets. The net change in restricted cash previously presented in financing activities of the Company’s consolidated statements of cash flows was removed and restricted cash was included in the reconciliation of beginning- and end-of-period totals of cash and cash equivalents and restricted cash. Cash paid by the Company when directly withholding shares from an employee’s share-based compensation award for tax-withholding purposes was reclassified from an operating activity within changes in income taxes to a financing activity in the consolidated statements of cash flows. There was no impact on the Company’s consolidated revenues, operating expenses, operating income, or earnings per share as a result of the reclassifications.

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 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 2016 Annual Report on Form 10-K. The following policy became effective for the Company during the six months ended June 30, 2017.

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

Share based awards are amortized to compensation expense on a straight line basis over the vesting period of awards or over the period to which the recipient first becomes eligible for retirement, whichever is shorter, with vesting accelerated upon death or disability. The Company recognizes forfeitures as they occur.

Adopted Accounting Pronouncements

In the first quarter of 2017, the Company adopted guidance issued by the Financial Accounting Standards Board (the “FASB”) which amended Accounting Standards Codification (“ASC”) Topic 740 with the addition of Balance Sheet Classification of Deferred Taxes.  The amendment was retrospectively adopted and resulted in reclassifications to the consolidated balance sheets to present all deferred tax assets and liabilities as noncurrent by jurisdiction.

In the first quarter of 2017, the Company adopted an amendment to ASC Topic 718, Compensation – Stock Compensation, which requires the income tax effects of awards to be recognized in the statement of operations when awards vest or are settled and allows employers to make a policy election to account for forfeitures as they occur. As a result of applying the provisions of the amendment, the Company recognized a $0.2 million cumulative effect adjustment to the opening balance of retained earnings as previously disclosed in the Company’s first quarter 2017 Quarterly Report on Form 10‑Q. The Company also made a policy election to account for forfeitures as they occur. The Company may experience volatility in its income tax provision as a result of recording all excess tax benefits and tax deficiencies in the income statement upon settlement of awards, which is primarily during the second quarter of each year. This provision of the amendment related to recognition of excess tax benefits and tax deficiencies was adopted prospectively; therefore, the prior period has not been adjusted for this provision. Cash paid by the Company to taxing authorities on the employee’s behalf for withheld shares was reclassified from an operating activity within changes in accounts payable, accrued expenses, and other liabilities to a financing activity in the consolidated statements of cash flows. The other provisions of the adopted amendment did not have a significant impact on the Company’s consolidated financial statements.

In the first quarter of 2017, the Company also adopted amendments to ASC Topic 230, Statement of Cash Flows, which provide classification guidance for restricted cash and certain cash receipts and cash payments presented in the statement of cash flows. The retrospective adoption of the amendments resulted in reclassification to the consolidated statement of cash flows to include restricted cash in the reconciliation of beginning- and end-of-period totals of cash and cash equivalents. Proceeds from the settlement of corporate-owned life insurance policies will be classified as cash provided by investing activities, and cash payments for premiums on such insurance policies will be classified as cash used in operating activities in the consolidated statements of cash flows.

Accounting Pronouncements Not Yet Adopted

ASC Topic 606, which amends the guidance in former ASC Topic 605, Revenue Recognition, provides a single comprehensive revenue recognition model for all contracts with customers and contains principles to apply to determine the measurement of revenue and timing of when it is recognized. The standard is effective for the Company on January 1, 2018. The Company is in the process of contract review and documentation in preparation for adopting the revenue recognition standard. The Company plans to adopt this standard on the modified retrospective basis and does not expect a significant impact on the consolidated financial statements.

An amendment to ASC Topic 715, Compensation – Retirement Benefits will require the service cost component of net benefit cost related to benefit plans accounted for under ASC Topic 715 to be included in the same line item or items as other compensation costs arising from services rendered by the related employees and will allow only the service cost component of the net benefit cost to be eligible for capitalization of internal costs. The amendment will also require the other components of net benefit cost, including pension settlement expense, to be presented in other income (costs) rather than in operating income. The amendment is effective for the Company beginning January 1, 2018.

ASC Topic 718 Compensation-Stock Compensation, was amended to provide guidance about which changes to the terms or conditions of a share-based payment award require the application of modification accounting. The amendment is effective for the Company beginning January 1, 2018 and is not expected to have a significant impact on the consolidated financial statements.

ASC Topic 842, Leases, which is effective for the Company beginning January 1, 2019, will require leases with a term greater than twelve months to be reflected as liabilities with associated right-of-use assets in the Company’s consolidated balance sheet. The Company is evaluating the impact of the new standard, which is required to be adopted on the modified retrospective basis, on the consolidated financial statements and disclosures.

Management believes that 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).

The Company’s long-term investment 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, 2017 and December 31, 2016, cash and cash equivalents totaling $46.0 million and $39.9 million, respectively, were not FDIC insured.

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
	2017				2016

	$	256,741	$	256,405	$	243,032	$	242,503

⁽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 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, 2017 and December 31, 2016 and considers the interest rate swap valuation in Level 2 of the fair value hierarchy.

⁽⁴⁾ Included in accrued expenses and other long-term liabilities, based on when expected payouts become due. The estimated fair value of contingent consideration for an earn-out agreement related to the September 2016 acquisition of LDS was determined by assessing Level 3 inputs with a discounted cash flow approach using various probability-weighted scenarios. The Level 3 assessments utilize a Monte Carlo simulation with inputs including scenarios of estimated revenues and gross margins to be achieved for the applicable performance periods, probability weightings assigned to the performance scenarios, and the discount rate applied, which was 11.9% and 12.3% as of June 30, 2017 and December 31, 2016, respectively. Subsequent changes to the fair value as a result of recurring assessments will be recognized in operating income.

The following table provides the changes in fair value of the liabilities measured at fair value using inputs categorized in Level 3 of the fair value hierarchy:

INCOME TAXES

INCOME TAXES

NOTE D – INCOME TAXES

The Company’s statutory federal tax rate is 35%. 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 34.6% and 27.1% for the three and six months ended June 30, 2017, respectively, and 37.5% and 37.8% for the three and six months ended June 30, 2016, respectively.

For the three and six months ended June 30, 2017 and 2016, the difference between the Company’s effective tax rate and the federal statutory rate primarily results from state income taxes, nondeductible expenses, changes in deferred tax valuation allowances, and changes in the cash surrender value of life insurance. The three- and six-month period ended June 30, 2016 reflects a benefit of 1.9% and 8.6%, respectively, related to the alternative fuel tax credit which expired December 31, 2016.

In the first quarter of 2017, the Company adopted an amendment to ASC Topic 718, Compensation – Stock Compensation, which requires the income tax effects of awards to be recognized in the statement of operations when awards vest or are settled and allows employers to make a policy election to account for forfeitures as they occur. The Company may experience volatility in its income tax provision as a result of recording all excess tax benefits and tax deficiencies in the income statement upon settlement of awards, which is primarily during the second quarter of each year. As a result of applying the provisions of the amendment beginning in the first quarter of 2017, the tax rate for the three and six months ended June 30, 2017 reflects a benefit of 4.8% and 10.8%, respectively.

As of June 30, 2017, 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, 2017 and concluded that, other than for certain deferred tax assets related to foreign net operating loss and 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, taxable income in carryback years, future taxable income, and tax planning strategies.

The Company paid state and foreign income taxes of $0.4 million and $2.2 million during the six months ended June 30, 2017 and 2016, respectively. During the six months ended June 30, 2017 and 2016 the Company received refunds of $0.1 million and $10.8 million, respectively, of federal and state income taxes that were paid in prior years.

Financing Arrangements

Credit Facility

The Company has a revolving credit facility (the “Credit Facility”) under its credit agreement which was amended and restated on January 2, 2015 (the “Amended and Restated Credit Agreement”). The Credit Facility, which matures on January 2, 2020, has an initial maximum credit amount of $150.0 million, including a swing line facility 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 Credit Facility allows the Company to request additional revolving commitments or incremental term loans thereunder up to an aggregate additional amount of $75.0 million, subject to certain additional conditions as provided in the Amended and Restated Credit Agreement. Principal payments under the Credit Facility are due upon maturity; 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 Amended and Restated Credit Agreement can either be, at the Company’s election: (i) at an alternate base rate (as defined in the Amended and Restated Credit Agreement) plus a spread; or (ii) at a Eurodollar rate (as defined in the Amended and Restated Credit Agreement) plus a spread. The applicable spread is dependent upon the Company’s adjusted leverage ratio (as defined in the Amended and Restated Credit Agreement). The Amended and Restated 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 Amended and Restated Credit Agreement at June 30, 2017.

In July 2017, the Company amended and extended its credit agreement (the “Second Amended and Restated Credit Agreement”) to increase the initial maximum credit amount of its Credit Facility from $150.0 million to $200.0 million, including a swing line facility and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $20.0 million, and to increase the additional revolving commitments or incremental term loans the Company may request under the facility from $75.0 million to $100.0 million. The maturity date of the Credit Facility was extended to July 7, 2022. The covenants and conditions of the Second Amended and Restated Credit Agreement are consistent with the previously amended credit agreement.

Interest Rate Swap

The Company has an 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 interest rate swap 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 3.35% based on the margin of the Credit Facility as of June 30, 2017. The fair value of the interest rate swap of $0.3 million and $0.5 million was recorded in other long-term liabilities in the consolidated balance sheet at June 30, 2017 and December 31, 2016, 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 interest rate swap 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 3.49% based on the margin of the Credit Facility as of June 30, 2017. The fair value of the interest rate swap of $0.2 million was recorded in other long-term assets in the consolidated balance sheet at June 30, 2017.

The unrealized loss 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, 2017 and December 31, 2016, and the change in the unrealized income (loss) on the interest rate swaps for the three and six months ended June 30, 2017 and 2016 was reported in other comprehensive loss, net of tax, in the consolidated statement of comprehensive income. The interest rate swaps are subject to certain customary provisions that could allow the counterparty to request immediate payment of the fair value liability 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, 2017.

Accounts Receivable Securitization Program

In March 2017, the Company entered into a second amendment to extend the maturity date of its accounts receivable securitization program until April 1, 2020 and increase the amount of cash proceeds provided under the facility from $100.0 million to $125.0 million, with 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. In April2017, the Company borrowed $10.0 million under the accounts receivable securitization program. As of June 30, 2017, $45.0 million was borrowed under the program. The Company was in compliance with the covenants under the accounts receivable securitization program as of June 30, 2017.

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, 2017, standby letters of credit of $19.0 million have been issued under the program, which reduced the available borrowing capacity to $61.0 million.

Letter of Credit Agreements and Surety Bond Programs

As of June 30, 2017, the Company had letters of credit outstanding of $19.6 million (including $19.0 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, 2017, surety bonds outstanding related to the self-insurance program totaled $59.4 million.

Notes Payable and Capital Leases

The Company has financed the purchase of certain revenue equipment, other equipment, and software through promissory note arrangements, including $37.9 million and $38.6 million for revenue equipment and software during the three and six months ended June 30, 2017, respectively.

⁽¹⁾ The Company amortizes actuarial losses over the average remaining active service period of the plan participants and does not use a corridor approach.

Nonunion Defined Benefit Pension Plan

The Company’s nonunion defined benefit pension plan covers substantially all noncontractual employees hired before January 1, 2006. In June 2013, the Company amended the nonunion defined benefit pension plan to freeze the participants’ final average compensation and years of credited service as of July 1, 2013. The plan amendment did not impact the vested benefits of retirees or former employees whose benefits have not yet been paid from the plan. Effective July 1, 2013, participants of the nonunion defined benefit pension plan who were active employees of the Company became eligible for the discretionary defined contribution feature of the Company’s nonunion 401(k) and defined contribution plan in which all eligible noncontractual employees hired subsequent to December 31, 2005 also participate.

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, 2017 of $0.7 million (pre-tax), or $0.5 million (after-tax), and $2.7 million (pre-tax), or $1.7 million (after-tax), respectively, related to $4.9 million and $9.7 million of lump-sum benefit distributions from the plan for the three and six months ended June 30, 2017, respectively, which included a $7.6 million purchase during the first quarter 2017 of a nonparticipating annuity contract from an insurance company to settle the pension obligation related to the vested benefits of approximately 50 plan participants and beneficiaries receiving monthly benefit payments at the time of the contract purchase. For the three and six months ended June 30, 2016, pension settlement expense of $0.6 million (pre-tax), or $0.3 million (after-tax), and $1.5 million (pre-tax), or $0.9 million (after-tax), respectively, was recognized related to $2.7 million and $7.2 million of lump-sum distributions from the plan for the same respective periods. Upon recognition of pension settlement expense, a corresponding reduction in the unrecognized net actuarial loss of the plan is recorded. The remaining pre-tax unrecognized net actuarial loss will continue to be amortized over the average remaining future years of service of the active plan participants. The Company will incur additional quarterly settlement expense related to lump-sum distributions from the nonunion defined benefit pension plan during the remainder of 2017.

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, 2017:

	Nonunion Defined

Accumulated benefit obligation	$	141,863

⁽¹⁾ Impacted by actuarial increases in the valuation of participant data as of January 1, 2017 and the actuarial loss from remeasurement upon settlement which was impacted by a decrease in the discount rate at June 30, 2017 compared to the December 31, 2016 measurement date.

⁽²⁾ Noncurrent liability recognized within pension and postretirement liabilities in the accompanying consolidated balance sheet at June 30, 2017.

Based upon current actuarial information, the Company does not have a minimum cash contribution requirement to its nonunion defined benefit pension plan for 2017. The plan’s preliminary adjusted funding target attainment percentage (“AFTAP”) is projected to be 107.8% as of the January 1, 2017 valuation date. The AFTAP is determined by measurements prescribed by the Internal Revenue Code, which differ from the funding measurements for financial statement reporting purposes.

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 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 specified in the ABF NMFA, which will remain in effect through March 31, 2018. The funding obligations to the pension plans are intended to satisfy the requirements imposed by the Pension Protection Act of 2006 (the “PPA”), 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 (the “Treasury Department”) 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”). ABF Freight received an Actuarial Certification of Plan Status for the Central States Pension Plan dated March 31, 2017, in which the plan’s actuary certified that, as of January 1, 2017, the plan is in critical and declining status, as defined by the Reform Act, with the funded percentage projected to be 40% as of the January 1, 2017 valuation date. 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 previously disclosed in the Company’s 2016 Annual Report on Form 10-K, ABF Freight received a Notice of Insolvency from the Road Carriers Local 707 Pension Fund (the “707 Pension Fund”) for the plan year beginning February 1, 2016. On March 1, 2017, the Pension Benefit Guaranty Corporation (“PBGC”) announced that beginning February 1, 2017 benefits to retirees were reduced to PBGC guarantee limits for insolvent multiemployer plans. The PBGC provides financial assistance to insolvent multiemployer plans to pay retiree benefits not to exceed guaranteed limits. The 707 Pension Fund will continue to administer the fund as the PBGC provides financial assistance. Approximately 1% of ABF Freight’s total multiemployer pension contributions are made to the 707 Pension Fund. Based on currently available information, it is the Company’s understanding that ABF Freight’s benefit contribution rates to the 707 Pension Fund under the ABF NMFA will be frozen and ABF Freight will be required to continue making contributions at the frozen rate throughout and after the current ABF NMFA contract period, which extends to March 31, 2018; however, there can be no assurance in this regard.

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 2016 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. Outstanding stock awards of less than 0.1 million for the three and six months ended June 30, 2017 and 0.4 million for the 2016 periods, were not included in the diluted earnings per share calculation because their inclusion would have the effect of increasing earnings per share.

OPERATING SEGMENT DATA

OPERATING SEGMENT DATA

OPERATING SEGMENT DATA

NOTE J – 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.

On November 3, 2016, the Company announced its plan to implement a new corporate structure which unified the Company’s sales, pricing, customer service, marketing, and capacity sourcing functions effective January 1, 2017. As previously reported in the Company’s 2016 Annual Report on Form 10‑K, the operating segments previously reported as Premium Logistics (Panther), Transportation Management (ABF Logistics), and Household Goods Moving Services (ABF Moving) were combined into a single asset‑light logistics operation reported under the ArcBest segment for the quarter and year ended December 31, 2016.

The Company has restated certain prior year operating segment data in this Quarterly Report on Form 10-Q to conform to the current year presentation. Segment revenues and expenses were adjusted to eliminate certain intercompany charges consistent with the manner in which they are reported under the new corporate structure. Certain intercompany charges among the previously reported Panther, ABF Logistics, and ABF Moving segments which were previously eliminated in the “Other and eliminations” line, are now eliminated within the ArcBest segment. There was no impact on the Company’s consolidated revenues, operating expenses, operating income, or earnings per share as a result of the restatements.

The Company’s reportable operating segments are impacted by seasonal fluctuations which affect tonnage, shipment 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:

· Asset-Based, which includes the results of operations of ABF Freight System, Inc. and certain other subsidiaries. The 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 Expedite, Truckload, and Truckload-Dedicated businesses as well as its premium logistics services; international freight transportation with air, ocean, and ground service offerings; household goods moving services to consumer, commercial, and government customers; warehousing management and distribution services; and managed transportation solutions.

ArcBest segment operations are influenced by seasonal fluctuations that impact customers’ supply chains and the resulting demand for expedite services. 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, may impact quarterly business levels. Expedite shipments of the ArcBest segment may decline during winter months because of post-holiday slowdowns but 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. The household goods 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. Shipment volumes of the ArcBest segment’s Truckload-Dedicated service offering, which was acquired in September 2016, are typically highest in the third and fourth calendar quarters of each year. Seasonal fluctuations are less apparent in the operating results of the Truckload and Truckload-Dedicated services of the ArcBest segment than in the industry as a whole because of business growth, including acquisitions, in this service offering of the segment.

· 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.

Emergency roadside service events of the FleetNet segment are favorably impacted by adverse 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.

RESTRUCTURING CHARGES

RESTRUCTURING CHARGES AND IMPAIRMENT

NOTE K – RESTRUCTURING CHARGES

On November 3, 2016, the Company announced its plan to implement a new corporate structure to better serve its customers. The new corporate structure unified the Company’s sales, pricing, customer service, marketing, and capacity sourcing functions effective January 1, 2017, and allows the Company to operate as one logistics provider under the ArcBest brand. As a result of the restructuring, the Company recorded $0.4 million and $2.0 million of restructuring charges in operating expenses during the three and six months ended June 30, 2017, respectively, primarily for employee-related costs.

The Company estimates it will incur restructuring charges of approximately $1.0 million during the remainder of 2017 primarily for employee-related costs associated with the plan announced during 2016.

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 62 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, 2017 and December 31, 2016, 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 $0.5 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, 2017

ORGANIZATION AND DESCRIPTION OF THE BUSINESS AND FINANCIAL STATEMENT PRESENTATION

Financial Statement Presentation - Basis of accounting

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 “Commission”) 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 2016 Annual Report on Form 10-K and other current filings with the Commission. In the opinion of management, all adjustments (which are of a normal and recurring nature) considered necessary for a fair presentation have been included.

Financial Statement Presentation - Restatements and reclassifications

Certain restatements have been made to the prior year’s operating segment data to conform to the current year presentation, reflecting the realignment of the Company’s organizational structure as announced on November 3, 2016. Under the new structure, the segments previously reported as Premium Logistics (Panther), Transportation Management (ABF Logistics), and Household Goods Moving Services (ABF Moving) are consolidated as a single Asset-Light logistics operation under ArcBest. Segment revenues and expenses were adjusted to eliminate certain intercompany charges consistent with the manner in which they are reported under the new corporate structure. Certain intercompany charges among the previously reported Panther, ABF Logistics, and ABF Moving segments which were previously eliminated in the “Other and eliminations” line, are now eliminated within the ArcBest segment. There was no impact on the Company’s consolidated revenues, operating expenses, operating income, or earnings per share as a result of the restatements.

Certain reclassifications have been made to the prior year’s consolidated financial statements to conform to the current year presentation. The insurance receivable for the amount of workers’ compensation and third-party casualty claims in excess of self-insurance retention limits, which was previously offset against the reserve included in accrued expenses, has been reclassed to other accounts receivable, resulting in an $8.7 million increase in other accounts receivable and a corresponding increase in accrued expenses in the consolidated balance sheet at December 31, 2016. Amounts totaling $18.6 million related to certain service centers of the Company’s Asset-Based operations previously recorded in leasehold improvements were reclassed to land and structures in the consolidated balance sheet at December 31, 2016. These reclassifications were previously reported in the Company’s first quarter 2017 Quarterly Report on Form 10-Q. The prior period impact of the reclassification of the insurance receivable is also reflected in the consolidated statements of cash flows for the six months ended June 30, 2016.

Other reclassifications were made to the consolidated financial statements to apply the provisions of accounting pronouncements adopted during the first quarter of 2017 related to deferred income taxes, share-based compensation, and cash flow classification (see Adopted Accounting Pronouncements within this Note). The Company’s deferred tax assets were reclassed, by jurisdiction, from current to long-term in the consolidated balance sheets. The net change in restricted cash previously presented in financing activities of the Company’s consolidated statements of cash flows was removed and restricted cash was included in the reconciliation of beginning- and end-of-period totals of cash and cash equivalents and restricted cash. Cash paid by the Company when directly withholding shares from an employee’s share-based compensation award for tax-withholding purposes was reclassified from an operating activity within changes in income taxes to a financing activity in the consolidated statements of cash flows. There was no impact on the Company’s consolidated revenues, operating expenses, operating income, or earnings per share as a result of the reclassifications.

Financial Statement Presentation - Estimates

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 financial statements and accompanying notes. Actual amounts may differ from those estimates.

Share-Based Compensation

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

Share based awards are amortized to compensation expense on a straight line basis over the vesting period of awards or over the period to which the recipient first becomes eligible for retirement, whichever is shorter, with vesting accelerated upon death or disability. The Company recognizes forfeitures as they occur.

Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Adopted

Adopted Accounting Pronouncements

In the first quarter of 2017, the Company adopted guidance issued by the Financial Accounting Standards Board (the “FASB”) which amended Accounting Standards Codification (“ASC”) Topic 740 with the addition of Balance Sheet Classification of Deferred Taxes.  The amendment was retrospectively adopted and resulted in reclassifications to the consolidated balance sheets to present all deferred tax assets and liabilities as noncurrent by jurisdiction.

In the first quarter of 2017, the Company adopted an amendment to ASC Topic 718, Compensation – Stock Compensation, which requires the income tax effects of awards to be recognized in the statement of operations when awards vest or are settled and allows employers to make a policy election to account for forfeitures as they occur. As a result of applying the provisions of the amendment, the Company recognized a $0.2 million cumulative effect adjustment to the opening balance of retained earnings as previously disclosed in the Company’s first quarter 2017 Quarterly Report on Form 10‑Q. The Company also made a policy election to account for forfeitures as they occur. The Company may experience volatility in its income tax provision as a result of recording all excess tax benefits and tax deficiencies in the income statement upon settlement of awards, which is primarily during the second quarter of each year. This provision of the amendment related to recognition of excess tax benefits and tax deficiencies was adopted prospectively; therefore, the prior period has not been adjusted for this provision. Cash paid by the Company to taxing authorities on the employee’s behalf for withheld shares was reclassified from an operating activity within changes in accounts payable, accrued expenses, and other liabilities to a financing activity in the consolidated statements of cash flows. The other provisions of the adopted amendment did not have a significant impact on the Company’s consolidated financial statements.

In the first quarter of 2017, the Company also adopted amendments to ASC Topic 230, Statement of Cash Flows, which provide classification guidance for restricted cash and certain cash receipts and cash payments presented in the statement of cash flows. The retrospective adoption of the amendments resulted in reclassification to the consolidated statement of cash flows to include restricted cash in the reconciliation of beginning- and end-of-period totals of cash and cash equivalents. Proceeds from the settlement of corporate-owned life insurance policies will be classified as cash provided by investing activities, and cash payments for premiums on such insurance policies will be classified as cash used in operating activities in the consolidated statements of cash flows.

Accounting Pronouncements Not Yet Adopted

ASC Topic 606, which amends the guidance in former ASC Topic 605, Revenue Recognition, provides a single comprehensive revenue recognition model for all contracts with customers and contains principles to apply to determine the measurement of revenue and timing of when it is recognized. The standard is effective for the Company on January 1, 2018. The Company is in the process of contract review and documentation in preparation for adopting the revenue recognition standard. The Company plans to adopt this standard on the modified retrospective basis and does not expect a significant impact on the consolidated financial statements.

An amendment to ASC Topic 715, Compensation – Retirement Benefits will require the service cost component of net benefit cost related to benefit plans accounted for under ASC Topic 715 to be included in the same line item or items as other compensation costs arising from services rendered by the related employees and will allow only the service cost component of the net benefit cost to be eligible for capitalization of internal costs. The amendment will also require the other components of net benefit cost, including pension settlement expense, to be presented in other income (costs) rather than in operating income. The amendment is effective for the Company beginning January 1, 2018.

ASC Topic 718 Compensation-Stock Compensation, was amended to provide guidance about which changes to the terms or conditions of a share-based payment award require the application of modification accounting. The amendment is effective for the Company beginning January 1, 2018 and is not expected to have a significant impact on the consolidated financial statements.

ASC Topic 842, Leases, which is effective for the Company beginning January 1, 2019, will require leases with a term greater than twelve months to be reflected as liabilities with associated right-of-use assets in the Company’s consolidated balance sheet. The Company is evaluating the impact of the new standard, which is required to be adopted on the modified retrospective basis, on the consolidated financial statements and disclosures.

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

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

⁽³⁾ Included in other long-term assets or 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, 2017 and December 31, 2016 and considers the interest rate swap valuation in Level 2 of the fair value hierarchy.

⁽⁴⁾ Included in accrued expenses and other long-term liabilities, based on when expected payouts become due. The estimated fair value of contingent consideration for an earn-out agreement related to the September 2016 acquisition of LDS was determined by assessing Level 3 inputs with a discounted cash flow approach using various probability-weighted scenarios. The Level 3 assessments utilize a Monte Carlo simulation with inputs including scenarios of estimated revenues and gross margins to be achieved for the applicable performance periods, probability weightings assigned to the performance scenarios, and the discount rate applied, which was 11.9% and 12.3% as of June 30, 2017 and December 31, 2016, respectively. Subsequent changes to the fair value as a result of recurring assessments will be recognized in operating income.
