Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 — Introduction and Basis of Presentation

Certain acronyms and terms used throughout this Quarterly Report are specific to the Company, commonly used in the trucking industry, or are otherwise frequently used throughout this document. Definitions for these acronyms and terms are provided in the "Glossary of Terms," available in the front of this document.

Description of Business

Knight-Swift is a transportation solutions provider, headquartered in Phoenix, Arizona. As of March 31, 2018, the Company's fleet of revenue equipment included 22,318 tractors (comprised of 18,182 company tractors and 4,136 independent contractor tractors), 71,590 trailers, and 9,121 intermodal containers. The Company's six reportable segments are Knight Trucking, Knight Logistics, Swift Truckload, Swift Dedicated, Swift Refrigerated, and Swift Intermodal.

2017 Merger

On September 8, 2017, the Company became Knight-Swift Transportation Holdings Inc. upon the effectiveness of the 2017 Merger. The Company accounted for the 2017 Merger using the acquisition method of accounting in accordance with GAAP. GAAP requires that either Knight or Swift is designated as the acquirer for accounting and financial reporting purposes ("Accounting Acquirer"). Based on the evidence available, Knight was designated as the Accounting Acquirer while Swift was the acquirer for legal purposes. For more information about the 2017 Merger refer to the Annual Report for the year ended December 31, 2017.

Abilene Acquisition

On March 16, 2018, the Company acquired all of the issued and outstanding equity interests of Abilene. Abilene's trucking and logistics businesses are included under the respective Knight segments. Please refer to Note 4 for more information about the Abilene Acquisition.

Basis of Presentation

The condensed consolidated financial statements and footnotes included in this Quarterly Report should be read in conjunction with the consolidated financial statements and footnotes included in Knight-Swift's Annual Report on Form 10-K for the year ended December 31, 2017. The condensed consolidated financial statements include the accounts of Knight-Swift Transportation Holdings Inc. and its subsidiaries. In management's opinion, these condensed consolidated financial statements were prepared in accordance with GAAP and include all adjustments necessary (consisting of normal recurring adjustments) for the fair statement of the periods presented.

With respect to transactional/durational data, references to years, such as "2018" and "2017" pertain to calendar years. Similarly, references to quarters, such as "first", "second", "third", and "fourth" pertain to calendar quarters.

Note regarding comparability — Based on the structure of the 2017 Merger, the reported results do not include the results of operations of Swift and its subsidiaries on and prior to the 2017 Merger, in accordance with the accounting treatment applicable to the transaction. Additionally, the reported results do not include the results of operations of Abilene and its subsidiaries on and prior to its acquisition by the Company on March 16, 2018 in accordance with the accounting treatment applicable to the transaction. Accordingly, comparisons between the Company's first quarter 2018 results and prior periods may not be meaningful.

Changes in Presentation

The Company's changes in presentation in the first quarter of 2018 were attributed to recently adopted accounting pronouncements. Refer to Note 2.

Seasonality

In the transportation industry, results of operations generally follow a seasonal pattern. Freight volumes in the first quarter are typically lower due to less consumer demand, customers reducing shipments following the holiday season, and inclement weather impeding operations. At the same time, operating expenses generally increase, and tractor productivity of the Company's fleet, independent contractors, and third-party carriers decreases during the winter months due to decreased fuel efficiency, increased cold-weather-related equipment maintenance and repairs, and increased insurance claims and costs attributed to higher accident frequency from harsh weather. During this period, the profitability of the Company's operations is generally lower than during other parts of the year. Additionally, the Company has seen surges between Thanksgiving and Christmas resulting from holiday shopping trends toward delivery of gifts purchased over the Internet, as well as the impact of shorter holiday seasons (Thanksgiving holiday recently falling closer to Christmas).

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) — CONTINUED

Note 2 — Recently Adopted Accounting Pronouncements

Revenue (ASC Topic 606): ASU 2014-09 — Revenue from Contracts with Customers

Summary of the Standard — In May 2014, the FASB issued ASU 2014-09, which established ASC Topic 606, Revenue from Contracts with Customers, and superseded the legacy revenue recognition requirements in ASC Topic 605. The core principle of the new standard is that companies should depict the transfer of promised goods or services to its customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard provides a five-step analysis for companies to apply in determining the timing, method, and amount of revenue recognition to achieve the core principle. The amendments in ASU 2014-09 became effective for public companies for annual reporting periods beginning after December 15, 2017 (in accordance with ASU 2015-14, which deferred the original effective date of ASU 2014-09). Companies may apply the amendments in ASU 2014-09 using the modified retrospective approach or a full retrospective approach, with early adoption permitted.

Adoption Method and Approach — The Company adopted ASC Topic 606 on January 1, 2018 by applying the modified retrospective approach to contracts not yet completed as of January 1, 2018, resulting in a cumulative-effect adjustment to retained earnings. See "Cumulative-effect Adjustment," below. Comparative information related to periods prior to January 1, 2018 continues to be reported under the legacy guidance in ASC Topic 605.

Five-Step Analysis — Management applied the five-step analysis to the Company's four trucking segments (Knight Trucking, Swift Truckload, Swift Dedicated, and Swift Refrigerated), as well as its intermodal and logistics businesses. The Company's other streams of revenue within Swift's non-reportable segments (specifically its leasing and captive insurance subsidiaries) were determined to be out of the scope of ASC Topic 606.

•

Contract Identification — Management has identified that a legally enforceable contract with its customers is executed by both parties at the point of pickup at the shipper's location, as evidenced by the bill of lading. Although the Company may have master agreements with its customers, these master agreements only establish general terms. There is no financial obligation to the shipper until the load is tendered/accepted and the Company takes possession of the load.

•

Performance Obligations — The Company's only performance obligation is transportation services. The Company's delivery, accessorial, and dedicated operations truck capacity in its dedicated operations represent a bundle of services that are highly interdependent and have the same pattern of transfer to the customer. These services are not capable of being distinct from one another. For example, the Company generally would not provide accessorial services or truck capacity without providing delivery services.

•

Transaction Price — Depending on the contract, the total transaction price may consist of mileage revenue, fuel surcharge revenue, accessorial fees, truck capacity, and/or non-cash consideration. Non-cash consideration is measured by the estimated fair value of the non-cash consideration at contract inception. There is no significant financing component in the transaction price, as the Company's customers generally pay within the contractual payment terms of 30 to 60 days.


•	Allocating Transaction Price to Performance Obligations — The transaction price is entirely allocated to the only performance obligation: transportation services.

•

Revenue Recognition — The performance obligation of providing transportation services is satisfied over time. Accordingly, revenue is recognized over time. Management estimates the amount of revenue in transit at period end based on the number of days completed of the dispatch (which is generally one to three days for the trucking segments, but can be longer for intermodal operations). Management believes this to be a faithful depiction of the transfer of services because if a load is dispatched, but terminates mid-route and the load is picked up by another carrier, then that carrier would not need to re-perform the services for the days already traveled. Recognizing revenue over time is a change from the Company's past practice, under which revenue was recognized at the point in time that the freight was delivered. Due to this change, the timing of revenue recognition (as well as the related variable costs) between reportable periods will change, compared to revenue recognition under ASC Topic 605. However, the net impact on the Company's results of operations on the current reportable period is immaterial and is expected to continue to be immaterial in future reportable periods.

There was no change in management's determination that the Company acts as the principal (rather than the agent) with respect to revenue recognition under ASC Topic 606, compared to ASC Topic 605. Accordingly, the Company continues to recognize revenue on a gross basis, consistent with past practices.

•Measuring in-transit revenue at period end (discussed above).

•

Estimating the allowance for doubtful accounts. The Company establishes an allowance for doubtful accounts based on historical experience and any known trends or uncertainties related to customer billing and account collectability. Management reviews the adequacy of its allowance for doubtful accounts on a quarterly basis. Uncollectible accounts are written off when deemed uncollectible, and accounts receivable are presented net of an allowance for doubtful accounts.

Practical Expedients — As permitted under ASU 2014-09 (and related ASUs), management employed the use of certain practical expedients in adopting ASC Topic 606, as follows:


•	The new guidance was only applied to those contracts that were not completed as of the date the Company adopted the new guidance, rather than to all revenue contracts because application of the practical expedient would not materially affect the Company's results.


•	The portfolio approach was applied in evaluating and accounting for contract costs, because application of the practical expedient would not materially affect the Company's results.


•	Remaining performance obligations are not disclosed, as the original expected duration of the contract is one year or less.


•	Incremental costs related to obtaining contracts are expensed as incurred, as they would otherwise be amortized over less than one year.

Revenue Disaggregation — In considering the level at which the Company should disaggregate revenues pertaining to contracts with customers, management determined that there are no significant differences between segments in how the nature, amount, timing, and uncertainty of revenue or cash flows are affected by economic factors. Additionally, management considered how and where the Company has communicated information about revenue for various purposes, including disclosures outside of the financial statements; how information is regularly reviewed by the Company's chief operating decision makers for evaluating financial performance of the Company's segments; among others. Based on these considerations, management determined that revenues should be disaggregated by reportable segment and the required quantitative and qualitative disclosures are included in Note 18.

Contract Balances — The $17.3 million and $17.0 million in-transit revenue balances are included in "Trade receivables, net of allowance for doubtful accounts" in the condensed consolidated balance sheets as of March 31, 2018 and January 1, 2018, respectively. The Company's contract liability balances as of March 31, 2018 and January 1, 2018 were immaterial.

Cash (ASC Topic 230): ASU 2016-18 — Restricted Cash and ASU 2016-15 — Classification of Certain Cash Receipts and Cash Payments

Summary of the Standards — The FASB issued ASU 2016-18, Restricted Cash, in November 2016. The amendments in ASU 2016-18 require that a statement of cash flows explains the change during the reporting period in the total of cash, cash equivalents, including restricted cash and restricted cash equivalents. As such, restricted cash and restricted cash equivalents amounts should be included in the beginning and ending cash balances in the reconciliation at the bottom of the statement of cash flows.

The FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, in August 2016. This ASU has several amendments, which are designed to reduce existing diversity in practice of how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The ASU addresses eight specific cash flow issues: 1) debt prepayment or extinguishment costs, 2) settlement of zero-coupon debt instruments, 3) contingent consideration payments made after a business combination, 4) proceeds from settlement of insurance claims, 5) proceeds from settlement of corporate-owned life insurance policies, 6) distributions received from equity method investees, 7) beneficial interests in securitization transactions, and 8) separately identifiable cash flows and application of the predominance principle.

Adoption Method and Approach — For public companies, the amendments in these ASUs became effective for annual reporting periods beginning after December 15, 2017. The retrospective transition method is required, with prior periods adjusted to align with the current period presentation. Early adoption was permitted; however, the Company adopted the amendments in these ASUs in the first quarter of 2018.

Impact of Adoption — The table below summarizes the impact on the statement of cash flows of adopting ASU 2016-18, including changes made to the statement of cash flows captions. As allowed by the amendments in ASU 2016-15, the Company elected to apply the "Nature of Distribution" approach to classifying cash flows from its equity method investments in Transportation Resource Partners. However, retrospectively applying this approach did not change the presentation of the first quarter 2017 statement of cash flows. There were no other cash flow issues in ASU 2016-15 that impacted the Company's statement of cash flows presentation.

Income Taxes (ASC Topic 740): ASU 2018-05 —Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118

Summary of the Standard — The FASB issued ASU 2018-05, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118, in March 2018. ASU 2018-05 provides clarification to address uncertainty or diversity in views about the application of ASC Topic 740 in the period of enactment.

Current Period Impact of Adoption — During the first quarter of 2018, the Company had not updated any estimated provisional amounts previously reported and is still evaluating the impact of the Tax Cuts and Jobs Act. Management will continue to assess its provision for income taxes as future guidance is issued but does not currently anticipate significant revisions will be necessary. Any such revisions will be treated in accordance with the measurement period guidance outline in Staff Accounting Bulletin No. 118.

Other ASUs

There were various other ASUs that became effective in the first quarter of 2018, which did not have a material impact on the Company's results of operations, financial position, cash flows, or disclosures.

Note 4 — Merger and Acquisition

2017 Merger

Information about the accounting treatment of the 2017 Merger including details of the transaction, determination of the total fair value consideration, and allocation of the purchase price, are included in the Company's Annual Report for the year ended December 31, 2017.

The purchase price allocation for the 2017 Merger is open for adjustments and has been allocated based on estimated fair values of the assets acquired and liabilities assumed at the acquisition date, pending the finalization of certain identified contingent liabilities and the calculation of deferred taxes based upon the underlying tax basis of assets acquired and liabilities assumed and assessment of other tax related items. Management expects that, as more information is obtained, the purchase price allocation may change. Any future adjustments to the purchase price allocation, including changes within identifiable intangible assets or estimation uncertainty impacted by market conditions, may impact future net earnings. The purchase price allocation adjustments can be made through the end of the measurement period, which is not to exceed one year from the acquisition date.

Abilene Acquisition

On March 16, 2018, the Company purchased 100.0% of the equity interests of Abilene. Abilene is a diversified truckload carrier located in Richmond, Virginia operating throughout the US and Canada.

The total consideration of $103.2 million consisted of approximately $80.4 million in cash consideration to the sellers, plus approximately $22.8 million for debt payoffs. The Company funded the Abilene Acquisition through cash-on-hand and borrowing on the Revolver on the date of the transaction. At closing, $7.0 million of the purchase price was placed in escrow to secure the sellers' indemnification obligations and an additional $4.5 million of the purchase price was placed in escrow in respect of certain tax obligations of the sellers. The purchase price remains subject to further adjustments, including a post-closing true-up.

The equity purchase agreement included an election under the Internal Revenue Code Section 338(h)(10). Accordingly, the book and tax basis of the acquired assets and liabilities are the same as of the purchase date. The equity purchase agreement contains customary representations, warranties, covenants, and indemnification provisions.

The results of the acquired business have been included in the condensed consolidated financial statements since the date of acquisition and represent 1.4% of consolidated total assets as of March 31, 2018, 0.3% of total revenue, and 0.1% of net income for the quarter ended March 31, 2018. The Company recorded approximately $0.2 million of acquisition-related expenses, which are included within "Miscellaneous operating expenses" in the condensed consolidated income statement for the quarter ended March 31, 2018.

The goodwill recognized represents expected synergies from combining the operations of Abilene with the Company, including enhanced service offerings and sharing best practices in terms of driver recruiting and retention, as well as other intangible assets that did not meet the criteria for separate recognition. The goodwill is expected to be deductible for tax purposes.

The purchase price allocation for the Abilene Acquisition is preliminary and has been allocated based on estimated fair values of the assets acquired and liabilities assumed at the acquisition date, pending the completion of valuation of acquired tangible assets, an independent valuation of certain acquired intangible assets, assessment of lease agreements, assessment of certain liabilities, the calculation of deferred taxes based upon the underlying tax basis of assets acquired and liabilities assumed, and assessment of other tax related items. As the Company obtains more information, the preliminary purchase price allocation disclosed below is subject to change. Any future adjustments to the preliminary purchase price allocation, including changes within identifiable intangible assets or estimation uncertainty impacted by market conditions, may impact future net earnings. The purchase price allocation adjustments can be made through the end of the measurement period, which is not to exceed one year from the acquisition date.

Note 6 — Transportation Resource Partners

From 2003 through 2016, Knight entered into partnership agreements with entities that make privately-negotiated equity investments, including Transportation Resource Partners ("TRP"), Transportation Resource Partners III, LP ("TRP III"), TRP Capital Partners, LP ("TRP IV"), TRP CoInvest Partners, (NTI) I, LP ("TRP Coinvestment NTI"), and TRP CoInvest Partners, (QLS) I, LP ("TRP Coinvestment QLS"). In these agreements, Knight committed to invest in return for an ownership percentage.

The following table presents ownership and commitment information for Knight's investments in TRP partnerships:



	Knight's Ownership Interest⁽⁴⁾		Total Commitment (All Partners)		Knight's Contracted Commitment		Knight's Remaining Commitment
	(Dollars in thousands)

(1)	Knight's ownership interest in TRP III was 4.8% at December 31, 2017. Regarding Knight's remaining commitment, management anticipates that the following amounts will be due: $0.9 million in the remainder of 2018 and $0.8 million from 2019 through 2020.


(2)	Knight's ownership interest in TRP IV was 4.1% at December 31, 2017. Regarding Knight's remaining commitment, management anticipates that the following amounts will be due: $1.3 million in the remainder of 2018, $0.5 million from 2019 through 2020, $0.2 million from 2021 through 2022, and $0.1 million from 2023 through 2024.

(3)

The TRP Coinvestments are unconsolidated majority interests. Management considered the criteria set forth in ASC 323, Investments – Equity Method and Joint Ventures, to establish the appropriate accounting treatment for these investments. This guidance requires the use of the equity method for recording investments in limited partnerships where the "so minor" interest is not met. As such, the investments are being accounted for under the equity method. Knight's ownership interest reflects its ultimate ownership of the portfolio companies underlying the TRP Coinvestment NTI and TRP Coinvestment QLS legal entities.


(4)	Knight's share of the results is included within "Other Income" in the condensed consolidated income statements.

Net investment balances included in "Other long-term assets, restricted cash, and investments" in the condensed consolidated balance sheets were as follows:

Note 7 — Assets Held for Sale

As of March 31, 2018 and December 31, 2017, assets held for sale are carried at the lower of depreciated cost or estimated fair value, less expected selling costs when the required criteria, as defined by ASC Topic 360, Property, Plant, and Equipment, are satisfied. Depreciation ceases on the date that the held for sale criteria are met. The Company expects to sell these assets within the next twelve months. Revenue equipment held for sale totaled $30.4 million and $25.2 million as of March 31, 2018 and December 31, 2017, respectively.

Note 9 — Income Taxes

Effective Tax Rate — The quarter ended March 31, 2018 and March 31, 2017 effective tax rates were 21.2% and 35.3%, respectively. The decrease was primarily a result of the Tax Cuts and Jobs Act of 2017. The Company recognized discrete items relating to stock compensation deductions and a favorable audit settlement of nondeductible penalties during the quarter ended March 31, 2018. The Company also recognized stock compensation deductions as a discrete item during the quarter ended March 31, 2017.

Valuation Allowance — The Company has not established a valuation allowance as it has been determined that, based upon available evidence, a valuation allowance is not required. Management believes that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets. All other deferred tax assets are expected to be realized and utilized by continued profitability in future periods.

Unrecognized Tax Benefits — The Company believes it is reasonably possible that a decrease of up to $0.7 million in unrecognized tax benefits related to federal tax credit claims for refunds may be necessary within the coming year due to a potential settlement of the claims with the relevant taxing authority.

Interest and Penalties — Accrued interest and penalties related to unrecognized tax benefits as of March 31, 2018 and December 31, 2017 were approximately $0.5 million and $0.3 million, respectively.

Tax Examinations — Certain of the Company's subsidiaries are currently under examination by various state jurisdictions for tax years ranging from 2011 through 2016. At the completion of these examinations, management does not expect any adjustments that would have a material impact on the Company's effective tax rate. Years subsequent to 2012 remain subject to examination.

Note 10 — Accounts Receivable Securitization

The 2015 RSA is a secured borrowing that is collateralized by the Company's eligible receivables, for which the Company is the servicing agent. The Company's eligible receivables are included in "Trade receivables, net of allowance for doubtful accounts" in the condensed consolidated balance sheets. Based on eligible receivables at March 31, 2018, the Company's borrowing base for the 2015 RSA was $281.9 million, while outstanding borrowings included in "Accounts receivable securitization" in the condensed consolidated balance sheets were $280.0 million. As of March 31, 2018, the Company's eligible receivables generally have high credit quality, as determined by the obligor's corporate credit rating.

As of March 31, 2018 and December 31, 2017, interest accrued on the 2015 RSA's aggregate principal balance at a rate of 2.4% and 2.1%, respectively. Program fees and unused commitment fees are recorded in "Interest expense" in the condensed consolidated income statements. The Company incurred program fees of $2.0 million related to the 2015 RSA during the quarter ended March 31, 2018.

The 2015 RSA is subject to customary fees and contains various customary affirmative and negative covenants, representations and warranties, and default and termination provisions. The Company was in compliance with these covenants as of March 31, 2018. Collections on the underlying receivables by the Company are held for the benefit of Swift Receivables Company II, LLC and the various purchasers and are unavailable to satisfy claims of the Company and its subsidiaries.

Refer to Note 16 for information regarding the fair value of the 2015 RSA.

Note 13 — Contingencies and Legal Proceedings

Legal Proceedings

Information is provided below regarding the nature, status, and contingent loss amounts, if any, associated with the Company's pending legal matters. There are inherent uncertainties in these legal matters, some of which are beyond management's control, making the ultimate outcomes difficult to predict. Moreover, management's views and estimates related to these matters may change in the future, as new events and circumstances arise and the matters continue to develop.

The Company has made accruals with respect to its legal matters where appropriate, which are reflected in the condensed consolidated financial statements. The Company has recorded an aggregate accrual of approximately $120.4 million relating to the Company's outstanding legal proceedings as of March 31, 2018.

Based on management's present knowledge of the facts and (in certain cases) advice of outside counsel, management does not believe that loss contingencies arising from pending matters are likely to have a material adverse effect on the Company's overall financial position, operating results, or cash flows after taking into account any existing accruals. However, actual outcomes could be material to the Company's financial position, operating results, or cash flows for any particular period.



EMPLOYEE COMPENSATION AND PAY PRACTICES MATTERS
Washington Overtime Class Actions
The plaintiffs allege one or more of the following, pertaining to Washington state-based driving associates: that Swift 1) failed to pay minimum wage; 2) failed to pay overtime; 3) failed to pay all wages due at established pay periods; 4) failed to provide proper meal and rest periods; 5) failed to provide accurate wage statements; and 6) unlawfully deducted from employee wages. The plaintiffs seek unpaid wages, exemplary damages, interest, other costs, and attorneys' fees.
Plaintiff(s)	Defendant(s)	Date instituted	Court or agency currently pending in
Troy Slack ⁽¹⁾	Swift Transportation Company of Arizona, LLC and Swift Transportation Corporation	September 9, 2011	United States District Court for the Western District of Washington
Recent Developments and Current Status
On August 29, 2017, the parties in the Slack case reached a settlement. The parties are currently disputing the scope of the settlement release. The likelihood that a loss has been incurred is probable and estimable, and the loss has accordingly been accrued.

INDEPENDENT CONTRACTOR MATTERS
Ninth Circuit Independent Contractor Misclassification Class Action
The putative class alleges that Swift misclassified independent contractors as independent contractors, instead of employees, in violation of the FLSA and various state laws. The lawsuit also raises certain related issues with respect to the lease agreements that certain independent contractors have entered into with Interstate Equipment Leasing, LLC. The putative class seeks unpaid wages, liquidated damages, interest, other costs, and attorneys' fees.
Plaintiff(s)	Defendant(s)	Date instituted	Court or agency currently pending in

Recent Developments and Current Status
In January 2017, the district court issued an order finding that the plaintiffs had signed contracts of employment and thus the case could properly proceed in court, instead of arbitration. Swift has appealed this decision to the Ninth Circuit and the parties have discussed settlement. Based on the above, the likelihood that a loss has been incurred is probable and estimable, and the loss has accordingly been accrued.

INDEPENDENT CONTRACTOR MATTERS
Utah Collective and Individual Arbitration
The plaintiffs allege that the Central Parties (defined below) misclassified independent contractors as independent contractors, instead of employees, in violation of the FLSA and various state laws. The putative class seeks unpaid wages, liquidated damages, interest, other costs, and attorneys' fees.
Plaintiff(s)	Defendant(s)	Date instituted	Court or agency currently pending in
Gabriel Ciluffo, Kevin Shire, and Bryan Ratterree ⁽¹⁾	Central Refrigerated Service, Inc., Central Leasing, Inc., Jon Isaacson, and Jerry Moyes (the "Central Parties"), as well as Swift Transportation Company	June 1, 2012	American Arbitration Association
Recent Developments and Current Status
In October 2016, the arbitrator ruled that approximately 1,300 Central Refrigerated Service, Inc. drivers should have been classified as employees, not independent contractors. The arbitrator ruled that damages could ultimately be assessed in a collective proceeding and denied Swift's motion to decertify the collective proceeding. On April 14, 2017, the parties reached a settlement of the matter. On April 3, 2018, the Court granted final approval of the settlement. The likelihood that a loss has been incurred is probable and estimable, and the loss has accordingly been accrued.

Self Insurance

The Company is insured against auto liability ("AL") claims under a primary self-insured retention ("SIR") policy. Knight's AL claims have SIRs ranging from $1.0 million to $3.0 million per occurrence and in some years, depending on the applicable policy year, Knight has been responsible for aggregate losses up to $1.5 million within the primary AL layer.

For the policy period March 1, 2018 to March 1, 2019, the Knight SIR is $1.0 million, subject to an annual aggregate limit. For the policy period March 1, 2017 to March 1, 2018, the Knight SIR was $1.0 million, subject to an annual aggregate limit. For the policy period March 1, 2016 to March 1, 2017, the Knight SIR was $2.5 million with no additional aggregate limits or deductibles within the primary AL policy. The Company secured excess liability coverage up to $130.0 million per occurrence for the Knight policy periods March 1, 2018 to March 1, 2019, March 1, 2017 to March 1, 2018, and March 1, 2016 to March 1, 2017. Knight also carries a $2.5 million aggregate deductible for any loss or losses within the excess coverage layer. Swift AL claims have $250.0 million of coverage per occurrence ($350.0 million aggregated limits through October 31, 2016), subject to a $10.0 million SIR per-occurrence.

The Company is self-insured for workers' compensation coverage. The Knight self-retention level has a maximum of $1.0 million per occurrence. Swift maintains statutory coverage limits, subject to a $5.0 million SIR for each accident or disease. Additionally, through Knight, the Company maintains primary and excess coverage for employee medical expenses and hospitalization, with self-insured retention of $0.2 million per claimant.

Note 15 — Weighted Average Shares Outstanding

Basic and diluted earnings per share, as presented in the condensed consolidated income statements, are calculated by dividing net income attributable to Knight-Swift by the respective weighted average common shares outstanding during the period.

The following table reconciles basic weighted average shares outstanding to diluted weighted average shares outstanding:



	Quarter Ended March 31,
	2018	2017
	(In thousands)
Basic weighted average common shares outstanding	178,160	80,310
Dilutive effect of equity awards	1,081	945
Diluted weighted average common shares outstanding	179,241	81,255
Anti-dilutive shares excluded from diluted earnings per share ⁽¹⁾	91	235


(1)	Shares were excluded from the dilutive-effect calculation because the outstanding awards' exercise prices were greater than the average market price of Knight-Swift's Class A Common Stock for the quarter ended March 31, 2018 and Knight's Common Stock for the quarter ended March 31, 2017.

Note 16 — Fair Value Measurement

ASC Topic 820, Fair Value Measurements and Disclosures, requires that the Company disclose estimated fair values for its financial instruments. The estimated fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market for the asset or liability. Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Changes in assumptions could significantly affect these estimates. Because the fair value is estimated as of March 31, 2018 and December 31, 2017, the amounts that will actually be realized or paid at settlement or maturity of the instruments in the future could be significantly different.

The tables below exclude certain financial instruments. The excluded financial instruments are as follows: cash and cash equivalents, restricted cash, net accounts receivable, income tax refund receivable, and accounts payable. The estimated fair value of these financial instruments approximate carrying value as they are short-term in nature. Additionally, for notes payable under revolving lines of credit, fair value approximates the carrying value due to the variable interest rate. For capital leases, the carrying value approximates the fair value. The table below also excludes financial instruments reported at estimated fair value on a recurring basis. See "Recurring Fair Value Measurements." All remaining balance sheet amounts excluded from the table below are not considered financial instruments subject to this disclosure.

Revolver, due October 2022	55,000		55,000		125,000		125,000

The carrying amounts of the financial instruments shown in the table are included in the condensed consolidated balance sheets, as follows:


(1)	Restricted investments are included in "Restricted investments, held to maturity, amortized cost."


(2)	These instruments are trading securities and are included within "Other long-term assets, restricted cash, and investments."


(3)	The Term Loan is included in "Long-term debt, less current portion." The carrying value is net of $0.6 million and $0.6 million deferred loan costs as of March 31, 2018 and December 31, 2017, respectively.

The estimated fair values of the financial instruments shown in the above table as of March 31, 2018 and December 31, 2017, represent management's best estimates of the amounts that would be received to sell those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants at that date. The estimated fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the estimated fair value measurement reflects management's own judgments about the assumptions that market participants would use in pricing the asset or liability. These judgments are developed by the Company based on the best information available under the circumstances.

The following summary presents a description of the methods and assumptions used to estimate the fair value of each class of financial instrument.

Restricted Investments, Money Market Funds, and Debt Securities — The estimated fair value of the Company's restricted investments is based on quoted prices in active markets that are readily and regularly obtainable. See Note 5 for additional investments disclosures.

Term Loan — The estimated fair value of the Term Loan approximates the face value. See Note 11 for additional debt disclosures.

Securitization of Accounts Receivable — The Company's securitization of accounts receivable consists of borrowings outstanding pursuant to the 2015 RSA as of March 31, 2018 and December 31, 2017, as discussed in Note 10. The estimated fair value of the 2015 RSA approximates the face value.

Note 18 — Information by Segment and Geography

Segment Information

Following the 2017 Merger, the Company continues to maintain Knight's and Swift's distinct brands in customer and driver-facing activities, while benefiting from the combined experience of its senior leadership. The Company's chief operating decision makers continue to assess performance based on Knight's and Swift's historical operating segments. As a result, the Company has six reportable segments, which are the historical reportable operating segments of Knight and Swift: Knight Trucking, Knight Logistics, Swift Truckload, Swift Dedicated, Swift Refrigerated, and Swift Intermodal, as well as the Swift non-reportable segments, discussed below.

Knight Segments:


•	Knight Trucking — The Knight Trucking segment is comprised of dry van, refrigerated, and drayage operations.


•	Knight Logistics — The Knight Logistics segment is primarily comprised of brokerage and intermodal operations. The Company also provides logistics freight management and other non-trucking services through its Knight Logistics business.

Abilene's trucking and logistics operations are included under the respective Knight segments beginning March 17, 2018.

Swift Segments:


•	Swift Truckload — The Swift Truckload segment consists of one-way movements over irregular routes throughout the United States, Mexico, and Canada.


•	Swift Dedicated — The Swift Dedicated segment devotes use of equipment to specific customers and offers tailored solutions under long-term contracts.


•	Swift Refrigerated — The Swift Refrigerated segment primarily consists of shipments for customers that require temperature-controlled trailers. These shipments include one-way movements over irregular routes, as well as dedicated truck operations.


•	Swift Intermodal — The Swift Intermodal segment includes revenue generated by moving freight over the rail in Swift's containers and other trailing equipment, combined with revenue for drayage to transport loads between the railheads and customer locations.

•

Swift Non-reportable Segments — The Swift non-reportable segments include Swift's logistics and freight brokerage services, as well as support services that Swift's subsidiaries provide to customers and independent contractors, including repair and maintenance shop services, equipment leasing and insurance. Certain of Swift's legal settlements and accruals, amortization of intangibles related to the 2017 Merger, and certain other corporate expenses are also included in the non-reportable segments.

Intersegment Eliminations

Certain operating segments provide transportation and related services for other affiliates outside of their reportable segment. For Knight operating segments, such services are billed at cost, and no profit is earned. For Swift operating segments, revenues for such services are based on negotiated rates, and are reflected as revenues of the billing segment. These rates are adjusted from time to time, based on market conditions. Such intersegment revenues and expenses are eliminated in Knight-Swift's consolidated results.

The following tables present the Company's financial information by segment:

Geographical Information

In the aggregate, total revenue from the Company's foreign operations was less than 5.0% of consolidated total revenue for the quarter ended March 31, 2018 and 2017. Additionally, long-lived assets on the Company's foreign subsidiary balance sheets were less than 5.0% of consolidated total assets as of March 31, 2018 and December 31, 2017.

Note 19 — Subsequent Event

In 2014, Knight formed Kold Trans LLC for the purpose of expanding its refrigerated trucking business. Knight was entitled to 80% of the profits of the entity and had effective control over the management of the entity. The financial activities of this entity were consolidated into the Company's consolidated financial statements, with the noncontrolling interest presented as a separate component. On April 1, 2018, Knight acquired the remaining 20.0% ownership interest in the entity. This will decrease consolidated additional paid-in capital by $2.5 million in the second quarter of 2018.

Executive Summary

Company Overview

2017 Merger — On September 8, 2017, the Company became Knight-Swift Transportation Holdings Inc. upon the effectiveness of the 2017 Merger. Immediately upon the consummation of the 2017 Merger, former Knight stockholders and former Swift stockholders owned approximately 46.0% and 54.0%, respectively, of the Company. Upon closing of the 2017 Merger, the shares of Knight common stock that previously traded under the ticker symbol "KNX" ceased trading and were delisted from the NYSE. Our shares of Class A common stock commenced trading on the NYSE on a post-reverse split basis under the ticker symbol "KNX" on September 11, 2017.

The Company accounted for the 2017 Merger using the acquisition method of accounting in accordance with GAAP. GAAP requires that either Knight or Swift is designated as the acquirer for accounting and financial reporting purposes ("Accounting Acquirer"). Based on the evidence available, Knight was designated as the Accounting Acquirer while Swift was the acquirer for legal purposes. For more information about the 2017 Merger refer to the Annual Report for the year ended December 31, 2017.

Abilene Acquisition — On March 16, 2018 the Company acquired all of the issued and outstanding equity interests of Abilene. Please refer to Note 4 in Part I, Item 1 of this Quarterly Report for more information about the Abilene Acquisition.

Segments — Our six reportable segments are Knight Trucking, Knight Logistics, Swift Truckload, Swift Dedicated, Swift Refrigerated, and Swift Intermodal. Additionally, Swift has various non-reportable segments. Refer to Note 18 in Part I, Item 1 of this Quarterly Report for descriptions of our segments.

Revenue — We offer a broad range of full truckload, intermodal, brokerage, and logistics services within North America's largest for-hire truckload tractor fleet, operated through a nationwide network of terminals, and contractual access to thousands of third-party capacity providers. Our objective is to operate our trucking and logistics businesses with industry-leading margins and growth while providing safe, high-quality, cost-effective solutions for our customers.

•

Our trucking services include dry van, refrigerated, dedicated, drayage, flatbed, and cross-border transportation of various products, goods, and materials for our diverse customer base. We primarily generate revenue before fuel surcharge by transporting freight for our customers through our trucking services in our Knight Trucking, Swift Truckload, Swift Dedicated, and Swift Refrigerated segments.

•

Our brokerage and intermodal operations provide a multitude of shipping solutions, including additional sources of truckload capacity and alternative transportation modes, by utilizing our vast network of third-party capacity providers and rail providers, as well as certain logistics, freight management, and other non-trucking services. Revenue before fuel surcharge in our brokerage and intermodal operations is generated through our Knight Logistics and Swift Intermodal segments.


•	Our Swift non-reportable segments generate revenue before fuel surcharge by providing freight management, sourcing, and other non-trucking services (such as repair and maintenance shop services and used equipment sales and leasing to independent contractors, as well as third parties).

•

In addition to the revenues earned from our customers for the trucking and non-trucking services discussed above, we also earn fuel surcharge revenue from our customers through our fuel surcharge program, which serves to recover a majority of our fuel costs. This applies only to loaded miles and typically does not offset non-paid empty miles, idle time, and out-of-route miles driven. Fuel surcharge programs involve a computation based on the change in national or regional fuel prices. These programs may update as often as weekly, but typically require a specified minimum change in fuel cost to prompt a change in fuel surcharge revenue. Therefore, many of these programs have a time lag between when fuel costs change and when the change is reflected in fuel surcharge revenue for our trucking segments.

Expenses — Our most significant expenses vary with miles traveled and include fuel, driving associate-related expenses (such as wages and benefits), and services purchased from independent contractors and other transportation providers (such as railroads, drayage providers, and other trucking companies). Maintenance and tire expenses, as well as the cost of insurance and claims generally vary with the miles we travel, but also have a controllable component based on safety improvements, fleet age, efficiency, and other factors. Our primary fixed costs are depreciation and lease expense for revenue equipment and terminals, interest expense, and non-driver employee compensation.

Recent Consolidated Results of Operations and Quarter-End Financial Condition

Trends and Outlook — The broader economy continues to show signs of growth in consumer spending, durable goods, and the prospects of increased manufacturing and construction, especially considering the recent tax relief from the Tax Cuts and Jobs Act. Additionally, the strong freight market from the end of 2017 carried into 2018 and provided non-contract revenue opportunities throughout the first quarter of 2018. Our results for the first quarter of 2018 were encouraging as we are seeing the results of our synergy efforts as well as the impacts of continued favorable market dynamics in terms of freight demand and constrained trucking capacity.

A shortage in drivers continues to be a headwind for the industry and will likely impact the ability to increase capacity and decrease utilization. We also believe that the ELD mandate began to have an impact on capacity late in the fourth quarter of 2017 and continuing into 2018. Given the strength in the freight market, as well as inflationary pressures related to driver wages, purchased transportation, and other costs, we expect to see rate increases in our contract business throughout 2018. In this environment, we will continue to monitor the markets in order to maximize both service to our customers and yield, as well as evaluate acquisition candidates and other opportunities that create value for our stockholders and further advance our long-term strategies.

Note: The reported results do not include the results of operations of Swift and its subsidiaries on and prior to the 2017 Merger, in accordance with the accounting treatment applicable to the transaction. Additionally, the reported results do not include the results of operations of Abilene on and prior to its acquisition by the Company on March 16, 2018 in accordance with the accounting treatment applicable to the transaction. Accordingly, comparisons between the Company's first quarter 2018 results and prior periods may not be meaningful.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $55.5 million increase in net income attributable to Knight-Swift to $70.4 million during the quarter ended March 31, 2018 from $14.9 million in quarter ended March 31, 2017, includes the following:

•

$21.8 million increase in Knight's operating income, primarily due to a 15.2% increase in revenue before fuel surcharge and intersegment transactions in the Knight Trucking segment, as revenue per loaded mile before fuel surcharge increased 16.1%, while average tractor count decreased by 1.9%. The increase in revenue before fuel surcharge and intersegment transactions was partially offset by an increase in driver associate-related costs;


•	$49.3 million in operating income from Swift's results for the quarter ended March 31, 2018, which included $10.3 million in amortization expense related to the intangible assets recorded in the 2017 Merger; and

•

$10.7 million increase in income tax expense. The increase was primarily due to inclusion of Swift's results for the quarter ended March 31, 2018, and was partially offset by impacts from the Tax Cuts and Jobs Act, which among other things, reduced the Company's federal corporate income tax rate from 35.0% to 21.0%. As such, the effective tax rate decreased from 35.3% in the quarter ended March 31, 2017 to 21.2% in the quarter ended March 31, 2018.

See additional discussion of our operating results within "Results of Operations — Consolidated" below.

In the quarter ended March 31, 2018, we generated $208.9 million in cash flows from operations and used $7.0 million for capital expenditures, net of equipment sales proceeds. During the quarter ended March 31, 2018, we returned $11.0 million to our stockholders in the form of quarterly dividends. We ended the quarter with $79.2 million in unrestricted cash and cash equivalents, $419.9 million in long-term debt (excluding the 2015 RSA and capital leases), and $5.3 billion of stockholders' equity. See discussion under "Liquidity and Capital Resources" and "Off-Balance Sheet Transactions" for additional information.

Operating Statistics

Our chief operating decision makers monitor the GAAP results of our reportable segments, as supplemented by certain non-GAAP information. Refer to "Non-GAAP Financial Measures" below for more details. Additionally, we use a number of primary indicators to monitor our revenue and expense performance and efficiency.

Average Revenue per Tractor — This operating statistic is used to measure productivity within our Knight Trucking, Swift Truckload, Swift Dedicated, and Swift Refrigerated segments and represents the average revenue per tractor based on revenue before fuel surcharge (before intersegment eliminations for our Knight Trucking segment) for the period.

Average Revenue per Load — This operating statistic is used within our Swift Intermodal and Knight Logistics segments and represents the average revenue per load based on revenue before fuel surcharge for the period.

Average Length of Haul — This represents the average of our miles with loaded trailer cargo and is used within our Knight Trucking, Swift Truckload, Swift Dedicated, and Swift Refrigerated segments.

Non-paid Empty Miles Percentage — Our Knight Trucking, Swift Truckload, and Swift Refrigerated segments monitor this operating statistic, which represents the average of our miles without trailer cargo.

Average Tractors — We use this measure for our Knight Trucking, Swift Truckload, Swift Dedicated, Swift Refrigerated, and Swift Intermodal segments. This operating statistic represents the average tractors in operation during the period.

Average Trailers — This represents the average trailers in operation during the period and is monitored within our Knight Trucking, Swift Truckload, Swift Dedicated, and Swift Refrigerated segments.

Average Containers — Our Swift Intermodal segment uses this measure to monitor the average number of containers in operation during the period.

Gross Margin Percentage – Brokerage Only — This measure is used in our brokerage business within the Knight Logistics segment and represents Knight's brokerage gross margin (revenue before intersegment transactions, less purchased transportation expense) as a percentage of Knight's brokerage revenue before intersegment transactions.

Operating Ratio and Adjusted Operating Ratio — Operating ratio is widely used in our industry as an assessment of management's effectiveness in controlling all categories of operating expenses. We consider these ratios as important measures of our operating profitability for each of our reportable segments. GAAP operating ratio is operating expenses as a percentage of total revenue, or the inverse of operating margin, and produces an indication of operating efficiency. Consolidated and segment Adjusted Operating Ratios are reconciled to their corresponding GAAP operating ratios under "Non-GAAP Financial Measures," below.

Segment Review

Knight Trucking Segment

We generate revenue in the Knight Trucking segment through dry van, refrigerated, and drayage service offerings. Generally, we are paid a predetermined rate per mile or per load for our trucking services. Additional revenues are generated in all four of our trucking segments (Knight Trucking, Swift Truckload, Swift Dedicated, and Swift Refrigerated) by charging for tractor and trailer detention, loading and unloading activities, dedicated services, and other specialized services, as well as through the collection of fuel surcharge revenue to mitigate the impact of increases in the cost of fuel. The main factors that affect the revenue generated by our trucking segments are rate per mile from our customers, the percentage of miles for which we are compensated, and the number of loaded miles we generate with our equipment.

The most significant expenses in the trucking segments are primarily variable and include fuel and fuel taxes, driving associate-related expenses (such as wages, benefits, training, and recruitment), and costs associated with independent contractors primarily included in "Purchased transportation" in the condensed consolidated income statements. Maintenance expense (which includes costs for replacement tires for our revenue equipment) and insurance and claims expenses have both fixed and variable components. These expenses generally vary with the miles we travel, but also have a controllable component based on safety, fleet age, efficiency, and other factors. The main fixed costs in the trucking segments are depreciation and rent expenses from leasing and acquiring revenue equipment and terminals, as well as compensating our non-driver employees.

(3)	The average age of the trailer fleet was 4.1 years in the quarter ended March 31, 2018, and 3.8 years in the quarter ended March 31, 2017.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The strong freight market and tight capacity supported pricing and non-contract revenue opportunities throughout the quarter. Accordingly, the Knight Trucking segment's total revenue increased $36.3 million, which included $3.6 million in revenue from Abilene from March 17, 2018 to March 31, 2018. Revenue before fuel surcharge and intersegment transactions increased 15.2% driven by a 16.1% increase in our revenue per loaded mile before fuel surcharge, partially offset by a 1.9% decrease in the average tractor count compared to the prior year quarter. Fuel surcharge revenue increased by $7.1 million, primarily due to higher average fuel prices.

Operating ratio and Adjusted Operating Ratio improved, primarily driven by the increases in revenue discussed above. Driving associate-related costs continued to present cost headwinds in the Knight Trucking segment, and are expected to continue to be challenging throughout 2018. Our focus in the Knight Trucking segment remains on developing our freight network, improving the productivity of our assets, and controlling costs, especially those related to sourcing and retaining drivers.

Knight Logistics Segment

The Knight Logistics segment is less asset-intensive than the trucking segments and is instead dependent upon capable non-driver employees, modern and effective information technology, and third-party capacity providers. Knight Logistics' revenue is generated primarily by its brokerage and intermodal operations. We also provide logistics, freight management and other non-trucking services to our customers through our Knight Logistics segment. We generate additional revenue by offering specialized logistics solutions (including, but not limited to, origin management, surge volume, disaster relief, special projects, and other logistic needs). Knight Logistics' revenue is mainly affected by the rates we obtain from customers, the freight volumes we ship through third-party capacity providers, and our ability to secure third-party capacity providers to transport customer freight.

The most significant expense in the Knight Logistics segment is the (primarily) variable cost of purchased transportation that we pay to third-party capacity providers (including rail providers), included in "Purchased transportation" in the consolidated income statements. Variability in this expense depends on truckload and rail capacity, availability of third-party capacity providers, rates charged to customers, and current freight demand and customer shipping needs. Fixed Knight Logistics operating expenses primarily include non-driver employee compensation and benefits recorded in "Salaries, wages, and benefits" in the consolidated income statements, and depreciation and amortization expense recorded in "Depreciation and amortization of property and equipment."

(1)	Defined under "Operating Statistics," above.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The Knight Logistics segment's total revenue increased $13.0 million, which included $0.1 million in revenue from Abilene. Brokerage revenue before intersegment transactions increased 25.2% in the Knight brokerage business, which is the largest component of the Knight Logistics segment. This was driven by a 28.4% increase in revenue per load, partially offset by a 2.5% decrease in load volume in the Knight brokerage business. Brokerage gross margin percentage slightly increased in the quarter ended March 31, 2018, compared to the quarter ended March 31, 2017, as the revenue per load increase was largely offset by the increase in purchased transportation costs given tight industry capacity. Operating ratio and Adjusted Operating Ratio slightly decreased, which was largely driven by the increase in revenue.

We plan to continue to invest in Knight's logistics service offerings, which we expect will continue to improve our return on capital compared with asset-based operations.

Swift Segments

Swift Truckload, Swift Dedicated, and Swift Refrigerated — We generate revenue in the Swift trucking segments through dry van, refrigerated, dedicated, drayage, flatbed, and cross-border service offerings. Refer to "Knight Trucking Segment," above for discussion of revenues generated and expenses incurred in all of the Company's trucking segments.

Swift Intermodal — The Swift Intermodal segment complements our regional operating model, allows us to better serve customers in longer haul lanes, and reduces our investment in fixed assets. Through the Swift Intermodal segment, we generate revenue by moving freight over the rail in our containers and other trailing equipment, combined with revenue for drayage to transport loads between railheads and customer locations. The most significant expense in the Swift Intermodal segment is the (primarily) variable cost of purchased transportation that we pay to third-party capacity providers (including rail providers), included in "Purchased transportation" in the consolidated income statements. Purchased transportation varies as it relates to rail capacity, freight demand, and customer shipping needs. The main fixed costs in the Swift Intermodal segment are depreciation of our containers and chassis, as well as non-driver employee compensation and benefits.

(2)	The Swift trucking segments operated an average of 15,065 tractors, of which 11,559 were company-owned tractors that had an average age of 2.5 years. The average age of Swift's trailer fleet was 8.2 years.

Swift Truckload, Swift Dedicated, and Swift Refrigerated — For the quarter ended March 31, 2018, the strong freight market positively affected average revenue per tractor in our Swift Truckload, Swift Dedicated, and Swift Refrigerated segments. Operating and Adjusted Operating Ratios in the Swift trucking segments have been improving, but are facing headwinds largely due to the challenging driver market we are experiencing. Sourcing and retaining high-quality driving associates remains a significant challenge and tractor counts have been accordingly decreasing in these segments. This has increased pressure on our recruiting costs, as well as driving associate wage expenses. In addition, Swift adopted more stringent hiring practices in October 2017 that negatively impacted driving associate headcount in the current period, but are expected to improve operating costs in the future. In an effort to combat these headwinds, we remain focused on our cost control initiatives, as well as improving yield, asset efficiency, and return on investment in Swift's trucking segments.

Swift Intermodal — For the quarter ended March 31, 2018, we saw improvements in the Swift Intermodal segment's revenue before surcharge, driven by a strong revenue per container and load counts. This segment's operating ratio and Adjusted Operating Ratio were positively affected by the aforementioned increase in load count as well as improved drayage efficiencies. We are focused on improving Swift Intermodal by right-sizing its cost infrastructure, increasing container turns, and driving operational efficiencies.

Consolidated Operating Expenses

The following tables present certain operating expenses from our consolidated income statements, including each operating expense as a percentage of total revenue and as a percentage of revenue before fuel surcharge. Fuel surcharge revenue can be volatile and is primarily dependent upon the cost of fuel, rather than operation expenses unrelated to fuel. Therefore, we believe that revenue before fuel surcharge is a better measure for analyzing many of our expenses and operating metrics.



	Quarter Ended March 31,						Increase (decrease)
	2018			2017
	(Dollars in thousands)
Salaries, wages, and benefits	$	361,673		$	82,510		338.3	%
% of total revenue	28.5		%	30.4		%	(190	bps)
% of revenue before fuel surcharge	32.2		%	33.7		%	(150	bps)

Salaries, wages, and benefits expense is primarily affected by the total number of miles driven by company driving associates, the rate per mile we pay our company driving associates, and employee benefits, including healthcare, workers' compensation, and other benefits. To a lesser extent, non-driver employee headcount, compensation, and benefits affect this expense. Driving associate wages is the largest component of salaries, wages, and benefits expense. We believe the driver market will continue to remain challenging and that several ongoing market factors have further reduced the pool of available driving associates. Having a sufficient number of qualified driving associates continues to be a major concern and our biggest headwind, although we continue to seek ways to attract and retain qualified driving associates, including investing in technology and terminals that improve the experience of driving associates. We expect driving associate pay to be inflationary, and we anticipate granting additional increases to our driving associates in the near term if supported by increases in the rates we receive from our customers as the market for qualified driving associates continues to tighten.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $279.2 million increase in consolidated salaries, wages, and benefits includes $269.7 million of expense from Swift's results for the quarter ended March 31, 2018. Further, Knight's salaries, wages, and benefits expense increased $9.5 million from the quarter ended March 31, 2017 to the quarter ended March 31, 2018, which included $1.2 million in expense from Abilene's results from March 17, 2018 to March 31, 2018. This increase was primarily related to Knight's driving associate-related costs.

Fuel	$	144,816		$	35,232		311.0	%
% of Total revenue	11.4		%	13.0		%	(160	bps)
% of Revenue before fuel surcharge	12.9		%	14.4		%	(150	bps)

Fuel expense consists primarily of diesel fuel expense for our company-owned tractors and fuel taxes. The primary factors affecting our fuel expense are the cost of diesel fuel, the fuel economy of our equipment, and the miles driven by company driving associates.

Our fuel surcharge programs help to offset increases in fuel prices, but apply only to loaded miles and typically do not offset non-paid empty miles, idle time, and out-of-route miles driven. Typical fuel surcharge programs involve a computation based on the change in national or regional fuel prices. These programs may update as often as weekly, but typically require a specified minimum change in fuel cost to prompt a change in fuel surcharge revenue for our trucking segments. Therefore, many of these programs have a time lag between when fuel costs change and when the change is reflected in fuel surcharge revenue. Due to this time lag, our fuel expense, net of fuel surcharge, negatively impacts our operating income during periods of sharply rising fuel costs and positively impacts our operating income during periods of falling fuel costs. We continue to utilize our fuel efficiency initiatives such as trailer blades, idle-control, managing tractor speeds, updating our fleet with more fuel-efficient engines, managing fuel procurement, and driving associate training programs that we believe contribute to controlling our fuel expense.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $109.6 million increase in consolidated fuel expense includes $103.3 million of expense from Swift's results for the quarter ended March 31, 2018. Knight's fuel expense increased $6.3 million from the quarter ended March 31, 2017 to the quarter ended March 31, 2018, which includes $0.9 million in expense from Abilene's results from March 17, 2018 to March 31, 2018. Miles driven by Knight's company driving associates increased and US diesel fuel prices were higher overall in the quarter ended March 31, 2018 at $3.02 per gallon, compared to the quarter ended March 31, 2017 at $2.57 per gallon.

% of Total revenue	6.7		%	7.6		%	(90	bps)
% of Revenue before fuel surcharge	7.6		%	8.4		%	(80	bps)

Operations and maintenance expense consists of direct operating expenses, equipment maintenance, and tire expense. Operations and maintenance expenses are affected by the age of our company-owned fleet of tractors and trailers. We expect the driver market to remain competitive throughout 2018, which could increase future driving associate development and recruiting costs and negatively affect our operations and maintenance expense. We expect to begin refreshing our Knight and Swift tractor fleets in the coming quarters, and anticipate that maintenance costs will gradually decrease as we reduce the average age of our fleet.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $64.4 million increase in consolidated operations and maintenance expense includes $63.9 million of expense from Swift's results for the quarter ended March 31, 2018. Knight's operations and maintenance expense increased $0.5 million from the quarter ended March 31, 2017 to the quarter ended March 31, 2018, which was entirely attributed to Abilene's results from March 17, 2018 to March 31, 2018.

% of Total revenue	4.7		%	3.2		%	150	bps
% of Revenue before fuel surcharge	5.3		%	3.5		%	180	bps

Insurance and claims expense consists of premiums for liability, physical damage, and cargo, and will vary based upon the frequency and severity of claims, as well as our level of self-insurance, and premium expense. In recent years, insurance carriers have raised premiums for many businesses, including transportation companies, and as a result, our insurance and claims expense could increase in the future, or we could raise our self-insured retention when our policies are renewed or replaced. Insurance and claims expense also varies based on the number of miles driven by company driving associates and independent contractors, the frequency and severity of accidents, trends in development factors used in actuarial accruals, and developments in large, prior-year claims.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $50.6 million increase in consolidated insurance and claims expense includes $49.5 million of expense from Swift's results for the quarter ended March 31, 2018. Knight's insurance and claims expense increased $1.1 million from the quarter ended March 31, 2017 to the quarter ended March 31, 2018, of which $0.1 million was attributed to Abilene's results from March 17, 2018 to March 31, 2018. As a percentage of Knight's revenue before fuel surcharge, Knight's insurance and claims expense remained relatively flat. In future periods, Swift's higher self-retention limits may cause our consolidated insurance and claims expense to fluctuate more.

Operating taxes and licenses include state franchise taxes, federal highway use taxes, property taxes, vehicle license and registration fees, fuel and mileage taxes, among others. The expense is impacted by changes in the tax rates and registration fees associated with our tractor fleet and regional operating facilities.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $18.7 million increase in consolidated operating taxes and licenses includes $17.4 million of expense from Swift's results for the quarter ended March 31, 2018. Knight's operating taxes and licenses expense increased $1.3 million from the quarter ended March 31, 2017 to the quarter ended March 31, 2018. As a percentage of Knight's revenue before fuel surcharge, Knight's operating taxes and licenses remained relatively flat from the quarter ended March 31, 2017 to the quarter ended March 31, 2018.

Depreciation and amortization of property and equipment	$	93,863		$	29,557		217.6	%
% of Total revenue	7.4		%	10.9		%	(350	bps)
% of Revenue before fuel surcharge	8.3		%	12.1		%	(380	bps)

Depreciation relates primarily to our owned tractors, trailers, ELDs and other communication units, and other similar assets. Changes to this fixed cost are generally attributed to increases or decreases to company-owned equipment, the relative percentage of owned versus leased equipment, and fluctuations in new equipment purchase prices, which have historically been precipitated in part by new or proposed federal and state regulations (such as the EPA engine emissions requirements relating to post-2014 model tractors and the California trailer efficiency requirements). Depreciation can also be affected by the cost of used equipment that we sell or trade and the replacement of older used equipment. Management periodically reviews the condition, average age, and reasonableness of estimated useful lives and salvage values of our equipment and considers such factors in light of our experience with similar assets, used equipment market conditions, and prevailing industry practice.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $64.3 million increase in consolidated depreciation and amortization of property and equipment is entirely due to Swift's results for the quarter ended March 31, 2018. Knight's depreciation and amortization of property and equipment remained flat from the quarter ended March 31, 2017 to the quarter ended March 31, 2018.

Amortization of intangibles primarily relates to intangible assets identified with the 2017 Merger. See Note 4 and Note 8 in Part I, Item 1, of this Quarterly Report for further details regarding the Company's intangible assets, historical amortization, and anticipated future amortization.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $10.4 million increase in consolidated amortization of intangibles is almost entirely attributed to Swift's amortization of the intangible assets identified with the 2017 Merger. The remaining amount is attributed to amortization of the intangible assets identified with the Abilene Acquisition.

% of Total revenue	4.2		%	0.5		%	370	bps
% of Revenue before fuel surcharge	4.7		%	0.5		%	420	bps

Rental expense consists primarily of payments for tractors and trailers financed with operating leases. The primary factors affecting the expense are the size of our revenue equipment fleet and the relative percentage of owned versus leased equipment.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $51.6 million increase in consolidated rental expense includes $51.5 million of expense from Swift's results for the quarter ended March 31, 2018. Knight's rental expense remained relatively flat from the quarter ended March 31, 2017 to the quarter ended March 31, 2018, and remained flat as a percentage of revenue before fuel surcharge. Consolidated rental expense as a percentage of consolidated revenue before fuel surcharge increased, as Swift historically obtained a larger portion of its equipment through operating leases, as compared to Knight.

% of Total revenue	25.5		%	21.6		%	390	bps
% of Revenue before fuel surcharge	28.8		%	23.9		%	490	bps

Purchased transportation expense is comprised of (1) payments to independent contractors in our trucking operations and (2) payments to third-party capacity providers related to logistics, freight management, and non-trucking services in our logistics and intermodal businesses. Purchased transportation is generally affected by capacity in the market as well changes in fuel prices. As capacity tightens, our payments to third-party capacity providers and to independent contractors tend to increase. Additionally, as fuel prices increase, payments to third-party capacity providers and independent contractors increase.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $265.7 million increase in consolidated purchased transportation expense includes $253.9 million of expense from Swift's results for the quarter ended March 31, 2018. Knight's purchased transportation expense increased by $11.8 million, which includes Abilene's results of $0.5 million from March 17, 2018 to March 31, 2018. The increase in Knight's purchased transportation expense was almost entirely attributed to the Knight Logistics segment.

We expect purchased transportation will increase as a percentage of revenue if we are successful in continuing to grow our logistics businesses, as well as Swift Intermodal. The increase could be partially offset if independent contractors exit the market with recent regulatory changes or further increased if we need to pay independent contractors more to stay with us in light of such regulatory changes. Third-party capacity has recently tightened, and we anticipate that this trend will continue throughout 2018.

Interest income — Interest income includes interest earned from financing revenue equipment to independent contractors, as well as interest earned from our investments.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $0.5 million increase in consolidated interest income includes $0.4 million of income from Swift's results for the quarter ended March 31, 2018. Knight's interest income increased by $0.1 million from the quarter ended March 31, 2017 to the quarter ended March 31, 2018.

Interest expense — Interest expense is comprised of debt and capital lease interest expense as well as amortization of deferred loan costs.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $6.7 million increase in consolidated interest expense is attributed to Swift's higher debt balances replacing Knight's lower debt balances in conjunction with the 2017 Debt Agreement entered into in September 2017. The increase includes $6.8 million of expense from Swift's results for the quarter ended March 31, 2018, which was partially offset by Knight's $0.1 million decrease in interest expense from the quarter ended March 31, 2017 to the quarter ended March 31, 2018.

Other income, net — Other income, net is primarily comprised of rental income, income (expense) from realized gains on sale of available-for-sale securities, unrealized gains from Knight's investments in Transportation Resource Partners accounted for under the equity method, as well as certain other non-operating income and expense that may arise outside of the normal course of business.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $1.4 million increase in consolidated other income, net included $1.3 million in income from Swift's results for the quarter ended March 31, 2018, which is almost entirely comprised of rental income. Knight's other income, net balance increased $0.1 million from the quarter ended March 31, 2017 to the quarter ended March 31, 2018.

Income tax benefit (expense) — In addition to the discussion below, Note 9 in Part I, Item 1 of this Quarterly Report provides further analysis related to income taxes.

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $10.7 million increase in consolidated income tax expense includes $9.3 million from Swift's results for the quarter ended March 31, 2018 and a $1.4 million increase in Knight's income tax expenses from the quarter ended March 31, 2017 to the quarter ended March 31, 2018. The consolidated effective tax rate in the quarter ended March 31, 2018 was 21.2%, as compared to Knight's effective tax rate of 35.3% in the quarter ended March 31, 2017. The effective tax rate decreased, primarily due to the impact of the Tax Cuts and Job Act, which among other things, included a reduction in the Company's federal corporate income tax rate from 35.0% to 21.0%.

Non-GAAP Financial Measures

The terms "Adjusted Net Income Attributable to Knight-Swift," "Adjusted EPS," and "Adjusted Operating Ratio", as we define them, are not presented in accordance with GAAP. These financial measures supplement our GAAP results in evaluating certain aspects of our business. We believe that using these measures improves comparability in analyzing our performance because they remove the impact of items from our operating results that, in our opinion, do not reflect our core operating performance. Management and the Board focus on Adjusted Net Income Attributable to Knight-Swift, Adjusted EPS, and Adjusted Operating Ratio as key measures of our performance, all of which are reconciled to the most comparable GAAP financial measures and further discussed below. We believe our presentation of these non-GAAP financial measures is useful because it provides investors and securities analysts the same information that we use internally for purposes of assessing our core operating performance.

Adjusted Net Income Attributable to Knight-Swift, Adjusted EPS, and Adjusted Operating Ratio are not substitutes for their comparable GAAP financial measures, such as net income, cash flows from operating activities, operating margin, or other measures prescribed by GAAP. There are limitations to using non-GAAP financial measures. Although we believe that they improve comparability in analyzing our period to period performance, they could limit comparability to other companies in our industry if those companies define these measures differently. Because of these limitations, our non-GAAP financial measures should not be considered measures of income generated by our business or discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by primarily relying on GAAP results and using non-GAAP financial measures on a supplemental basis.

Pursuant to the requirements of Regulation G, the following tables reconcile GAAP consolidated net income attributable to Knight-Swift to non-GAAP consolidated Adjusted Net Income attributable to Knight-Swift, GAAP consolidated earnings per diluted share to non-GAAP consolidated Adjusted EPS, GAAP consolidated operating ratio to non-GAAP consolidated Adjusted Operating Ratio, and GAAP reportable segment operating ratio to non-GAAP reportable segment Adjusted Operating Ratio.

Note: The reported results do not include the results of operations of Swift and its subsidiaries on and prior to the 2017 Merger, in accordance with the accounting treatment applicable to the transaction. Additionally, the reported results do not include the results of operations of Abilene on and prior to its acquisition by Knight on March 16, 2018 in accordance with the accounting treatment applicable to the transaction. Accordingly, comparisons between the Company's first quarter 2018 results and prior periods may not be meaningful.

Liquidity and Capital Resources

Sources of Liquidity

Our primary sources of liquidity are funds provided by operations and the following::



Source	March 31, 2018
	(In thousands)
Cash and cash equivalents, excluding restricted cash	$	79,184
Availability under Revolver, due October 2022 ⁽¹⁾	629,789
Availability under 2015 RSA, due January 2019 ⁽²⁾	1,900
Total unrestricted liquidity	$	710,873
Cash and cash equivalents – restricted ⁽³⁾	57,237
Restricted investments, held to maturity, amortized cost ⁽³⁾	22,281
Total liquidity, including restricted cash and restricted investments	$	790,391


(1)	As of March 31, 2018, we had $55.0 million in borrowings under our $800.0 million Revolver. We additionally had $115.2 million in outstanding letters of credit (discussed below), leaving $629.8 million available under the Revolver.


(2)	Based on eligible receivables at March 31, 2018, our borrowing base for the 2015 RSA was $281.9 million, while outstanding borrowings were $280.0 million, gross of deferred loan costs.

(3)

Restricted cash and restricted investments are primarily held by our captive insurance companies for claims payments. "Restricted cash and cash equivalents" consists of $55.6 million, which is included in "Cash and cash equivalents — restricted" in the condensed consolidated balance sheet and is held by Mohave and Red Rock for claims payments. The remaining $1.6 million is included in "Other long-term assets and restricted cash and other investments" and is held in escrow accounts to meet statutory requirements.

Uses of Liquidity

Our business requires substantial amounts of cash for operating activities, including salaries and wages paid to our employees, contract payments to independent contractors, insurance and claims payments, tax payments, and others. We also use large amounts of cash and credit for the following activities:

Capital Expenditures — When justified by customer demand, as well as our liquidity and our ability to generate acceptable returns, we make substantial cash capital expenditures to maintain a modern company tractor fleet, refresh our trailer fleet, fund replacement of our revenue equipment fleet, and, to a lesser extent, fund upgrades to our terminals and technology in our logistics service offerings. We believe we have ample flexibility with our trade cycle and purchase agreements to alter our current plans if economic or other conditions warrant.

Over the long-term, we will continue to have significant capital requirements, which may require us to seek additional borrowing, lease financing, or equity capital. The availability of financing or equity capital will depend upon our financial condition and results of operations as well as prevailing market conditions. If such additional borrowing, lease financing, or equity capital is not available at the time we need it, then we may need to borrow more under the Revolver (if not then fully drawn), extend the maturity of then-outstanding debt, rely on alternative financing arrangements, engage in asset sales, limit our fleet size, or operate our revenue equipment for longer periods.

There can be no assurance that we will be able to obtain additional debt under our existing financial arrangements to satisfy our ongoing capital requirements. However, we believe the combination of our expected cash flows, financing available through operating and capital leases, available funds under the 2015 RSA, and availability under the Revolver will be sufficient to fund our expected capital expenditures for at least the next twelve months.

Principal and Interest Payments — As of March 31, 2018, we had material debt and capital lease obligations of $866.9 million, which are discussed under "Material Debt Agreements," below. Certain cash flows from operations are committed to minimum payments of principal and interest on our debt or lease obligations. Additionally, when our financial position allows, we periodically make voluntary prepayments on our outstanding debt balances. Following the 2017 Merger, the combined company carries more debt than Knight historically carried, and the combined company has higher interest expense and exposure to interest rate fluctuations than Knight historically had.

Letters of Credit — Pursuant to the terms of the 2017 Debt Agreement, our lenders may issue standby letters of credit on our behalf. When we have letters of credit outstanding, it reduces the availability under our $800.0 million Revolver. Standby letters of credit are typically issued for the benefit of regulatory authorities, insurance companies and state departments of insurance for the purpose of satisfying certain collateral requirements, primarily related to our automobile, workers' compensation, and general insurance liabilities.

Share Repurchases — From time to time, and depending on free cash flow availability, debt levels, Class A common stock prices, general economic and market conditions, as well as Board approval, we may repurchase shares of our outstanding common stock. In February 2016, Swift's board of directors authorized $150.0 million in share repurchases, of which $62.9 million was assumed by the combined company, Knight-Swift, and remained available as of March 31, 2018.

Working Capital

As of March 31, 2018 and December 31, 2017, we had a working capital surplus of $277.1 million and $313.7 million, respectively.

Material Debt Agreements

As of March 31, 2018, we had $866.9 million in material debt obligations at the following carrying values:


•	$364.4 million: Term Loan, due October 2020, net of $0.6 million deferred loan costs


•	$280.0 million: 2015 RSA outstanding borrowings, due January 2019


•	$167.0 million: Capital lease obligations


•	$55.0 million: Revolver, due October 2022


•	$0.4 million: Other

As of December 31, 2017, we had $970.9 million in material debt obligations at the following carrying values:


•	$364.4 million: Term Loan, due October 2020, net of $0.6 million deferred loan costs


•	$305.0 million: 2015 RSA outstanding borrowings, due January 2019


•	$176.1 million: Capital lease obligations


•	$125.0 million: Revolver, due October 2022


•	$0.4 million: Other

Key terms and other details regarding our material debt agreements and capital leases are discussed in Notes 10, 11, and 12 in the footnotes to the condensed consolidated financial statements, included in Part I, Item 1: Financial Information, of this Quarterly Report, incorporated by reference herein.

Capital and Operating Leases

In addition to our net cash capital expenditures, Swift historically obtained a large portion of its revenue equipment, including tractors and trailers, through capital and operating leases. During the quarter ended March 31, 2018, we terminated various leases associated with revenue equipment that had an originating value of $70.5 million in the aggregate.

Cash Flow Analysis



	Quarter Ended March 31,						Increase (decrease)
	2018			2017
	(In thousands)
Net cash provided by operating activities	$	208,864		$	65,484		$	143,380
Net cash used in investing activities	(110,651		)	(5,619		)	(105,032		)
Net cash used in financing activities	(113,525		)	(23,088		)	(90,437		)

Net Cash Provided by Operating Activities

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $143.4 million increase in net cash provided by operating activities was primarily due to the $71.1 million increase in operating income, due to the factors discussed in "Results of Operations — Segment Review" and "Results of Operations — Consolidated Operating and Other Expenses," above, as well as timing differences in our working capital.

Net Cash Used in Investing Activities

Comparison Between the Quarters Ended March 31, 2018 and 2017 — The $105.0 million increase in net cash used in investing activities was due to $101.6 million in cash paid to acquire Abilene, net of $1.7 million in cash acquired from Abilene's balance sheet as of March 16, 2018.

Net Cash Provided by (Used in) Financing Activities

Comparison Between the Quarters Ended March 31, 2018 and 2017 — Net cash used in financing activities increased by $90.4 million, which was primarily due to repayments on the Company's Revolver and 2015 RSA.

Contractual Obligations

"Liquidity and Capital Resources," above, includes details regarding changes in our contractual obligations table during the quarter ended March 31, 2018. Aside from these items, there were no material changes to the contractual obligations table, which was included in our 2017 Annual Report.

Seasonality

Discussion regarding the impact of seasonality on our business is included in Note 1 in the notes to condensed consolidated financial statements, included in Part I, Item 1: Financial Information, in this Quarterly Report, incorporated by reference herein.

Inflation

Inflation can have an impact on our operating costs. A prolonged period of inflation could cause interest rates, fuel, wages, and other costs to increase, which would adversely affect our results of operations unless freight rates correspondingly increased. Consistent with trends in the trucking industry overall, we have recently experienced inflationary pressures with respect to driver wages, as compared to prior years.

Recently Issued Accounting Pronouncements

See Part I, Item 1: Financial Statements in this Quarterly Report, which is incorporated herein by reference, for the impact of recently issued accounting pronouncements on the Company's condensed consolidated financial statements, as follows:


•	Note 2 for accounting pronouncements adopted during the quarter ended March 31, 2018.


•	Note 3 for recently issued accounting pronouncements, not yet adopted by the Company as of March 31, 2018.

ITEM 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

We have exposure from variable interest rates, primarily related to our 2017 Debt Agreement and 2015 RSA. These variable interest rates are impacted by changes in short-term interest rates. We primarily manage interest rate exposure through a mix of variable rate debt (weighted average rate of 2.67% as of March 31, 2018) and fixed rate equipment lease financing. Assuming the level of borrowings as of March 31, 2018, a hypothetical one percentage point increase in interest rates would increase our annual interest expense by $7.0 million.

Commodity Price Risk

We have commodity exposure with respect to fuel used in company-owned tractors. Increases in fuel prices would continue to raise our operating costs, even after applying fuel surcharge revenue. Historically, we have been able to recover a majority of fuel price increases from our customers in the form of fuel surcharges. The weekly average diesel price per gallon in the United States, as reported by the United States Department of Energy, increased from an average of $2.57 per gallon for the quarter ended March 31, 2017 to $3.02 per gallon for the quarter ended March 31, 2018. We cannot predict the extent or speed of potential changes in fuel price levels in the future, the degree to which the lag effect of our fuel surcharge programs will impact us as a result of the timing and magnitude of such changes, or the extent to which effective fuel surcharges can be maintained and collected to offset such increases. We generally have not used derivative financial instruments to hedge our fuel price exposure in the past, but continue to evaluate this possibility.



ITEM 4.	CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We have established disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) to ensure that material information relating to us, including our consolidated subsidiaries, is made known to the officers who certify our financial reports and to other members of senior management and the Board. Our management, with the participation of our principal executive officer and principal financial officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures. Based on this evaluation, as of the end of the period covered by this Quarterly Report on Form 10-Q our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures are effective to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC rules and forms, and (2) accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2018, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We base our internal control over financial reporting on the criteria set forth in the 2013 COSO Internal Control: Integrated Framework.

We have confidence in our disclosure controls and procedures and internal control over financial reporting. Nevertheless, our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures and internal control over financial reporting will prevent all errors, misstatements, or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

PART II OTHER INFORMATION



ITEM 1.	LEGAL PROCEEDINGS

Information about our legal proceedings is included in Note 13 of the notes to our condensed consolidated financial statements, included in Part I, Item 1, of this Quarterly Report for the period ended March 31, 2018, and is incorporated by reference herein. Based on management's present knowledge of the facts and (in certain cases) advice of outside counsel, management does not believe that loss contingencies arising from pending matters are likely to have a material adverse effect on the Company's overall financial position, operating results, or cash flows after taking into account any existing accruals. However, actual outcomes could be material to the Company's financial position, operating results, or cash flows for any particular period.



ITEM 1A.	RISK FACTORS

In addition to the other information set forth in this Quarterly Report, the factors discussed in Part I, Item 1A, "Risk Factors" in our Annual Report for the year ended December 31, 2017 should be carefully considered as these risk factors could materially affect our business, financial condition, future results and/or our ability to maintain compliance with our debt covenants. The risks described in our Annual Report are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also adversely affect our business, financial condition, operating results and/or our ability to maintain compliance with our debt covenants. Except as described below, there has been no material change in our risk factors as previously disclosed in our 2017 Annual Report. For a detailed description of risk factors, refer to Part I, Item 1A, "Risk Factors", of our 2017 Annual Report.

Changes to trade regulation, quotas, duties or tariffs, caused by the changing US and geopolitical environments or otherwise, may increase our costs and adversely affect our business.

President Trump has expressed antipathy towards certain existing international trade agreements and made comments suggesting that he supports significantly increasing tariffs on goods imported into the US. Further, recent activity by the Trump administration has led to the imposition of tariffs on certain imported steel and aluminum. The implementation of these tariffs, as well as the imposition of additional tariffs or quotas or changes to certain trade agreements, could, among other things, increase the costs of the materials used by our suppliers to produce new revenue equipment or increase the price of fuel. Such cost increases for our revenue equipment suppliers would likely be passed on to us, and to the extent fuel prices increase, we may not be able to fully recover such increases through rate increases or our fuel surcharge program, either of which could have an adverse effect on our business.
