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 June 30, 2018, the Company's fleet of revenue equipment included 19,620 operational tractors (comprised of 16,076 company tractors and 3,544 independent contractor tractors), 69,490 trailers, and 9,117 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 Knight-Swift's 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 for the year ended December 31, 2017. The condensed consolidated financial statements in this Quarterly Report 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 pertain to calendar years. Similarly, references to quarters 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 quarter and year-to-date June 30, 2018 results and prior periods may not be meaningful.

Changes in Presentation

The Company's quarter and year-to-date June 30, 2018 changes in presentation were attributed to impacts from adopting accounting pronouncements (refer to Note 2) and simplifying the presentation of the consolidated balance sheets and statements of cash flows by reclassifying immaterial line items into other line items as indicated below.

Balance Sheet — The amounts presented in the Company's Annual Report for the year ended December 31, 2017 were reclassified to align with the June 30, 2018 presentation in this Quarterly Report as follows:


•	"Equipment sales receivables" and "Notes receivable, net" were reclassified to "Other current assets."


•	"Notes receivable, long-term" and "Other long-term assets, restricted cash, and investments" were reclassified to "Other long-term assets."


•	"Long term debt – current portion" was reclassified to "Capital lease obligations and long-term debt – current portion."


•	"Dividend payable – current portion" was reclassified to "Accrued liabilities."

Statement of Cash Flows — The amounts presented in Knight's Quarterly Report for the second quarter of 2017 were reclassified to align with the presentation in this Quarterly Report as follows:

•

"Transportation Resource Partners impairment," "Income from investment in Transportation Resource Partners," "Non-cash compensation expense for issuance of common stock to certain members of the Board of Directors," "Provision for doubtful accounts and notes receivable," and "Stock-based compensation expense, net" were reclassified to "Other adjustments to reconcile net income to net cash provided by operating activities."


•	Changes in "Other current assets," "Prepaid expenses," and "Other long-term assets" were reclassified to "Other assets and liabilities."


•	"Proceeds from notes receivable," "Change in restricted investments," "Cash payments to Transportation Resource Partners," and "Cash proceeds from Transportation Resource Partners" were reclassified to "Other cash flows from investing activities."


•	"Shares withheld for employee taxes related to stock-based compensation," "Cash distribution to noncontrolling interest holder," and "Proceeds from exercise of stock options" were reclassified to "Other cash flows from financing activities."

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. 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, beginning in the latter half of the third quarter and continuing into the fourth quarter, the Company typically experiences surges pertaining to 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).

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, resulting in a cumulative-effect adjustment to retained earnings. Comparative information related to periods prior to January 1, 2018 continues to be reported under the legacy guidance in ASC Topic 605. Practical expedients used include: 1) applying the guidance only to contracts not yet completed as of January 1, 2018, 2) using the portfolio approach in evaluating and accounting for contract costs, 3) not disclosing remaining performance obligations since the duration is one year or less, and 4) expensing incremental contract costs as they are incurred since they would have otherwise been amortized over less than one year.

Revenue Disaggregation — Based on how economic factors affect the nature, amount, timing, and uncertainty of revenue or cash flows, management determined that revenues should be disaggregated by reportable segment. The required quantitative and qualitative disclosures are included in Note 16.

Contract Balances — $19.0 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 June 30, 2018 and January 1, 2018, respectively. The Company's contract liability balances as of June 30, 2018 and January 1, 2018 were immaterial.

Cumulative-effect Adjustment — The cumulative-effect adjustment to the Company's consolidated opening balance sheet included increases in "Trade receivables, net of allowance for doubtful accounts" of $17.0 million, in "Purchased transportation" of $9.7 million, in "Accrued liabilities" of $0.2 million, in "Deferred tax liabilities" of $1.8 million, and in "Retained earnings" of $5.3 million.

Current Period Impact of Adoption — The required quantitative disclosures regarding the current period impact of adopting ASC Topic 606 on the condensed consolidated income statement and balance sheet are presented below. The amounts are entirely attributed to the in-transit accrual from the Company recognizing revenue over time under ASC Topic 606, compared to recognizing revenue at a point in time under ASC Topic 605.

Retained earnings	$	5,693

The Company's adoption of ASC Topic 606 did not materially affect basic earnings per share, diluted earnings per share, or cash flows from operations for the periods presented.

Accounting Policy — Under ASC Topic 606, revenue continues to be recognized on a gross basis, as the Company acts as the principal. The legally enforceable contract is evidenced by the bill of lading upon pickup at the shipper's location. The transaction price has no significant financing component and typically consists of cash consideration. Non-cash consideration is estimated at fair value at contract inception. The transaction price is entirely allocated to the only performance obligation, which is satisfied over time: transportation services. Accordingly, revenue is recognized over time, which is a change in the Company's past practice, resulting in an immaterial impact on the Company's results of operations. Management estimates the amount of revenue in transit at period end based on the number of days completed of the dispatch, which management believes to be a faithful depiction of the transfer of services. Significant judgments involved in applying ASC Topic 606 include measuring in-transit revenue and estimating the allowance for doubtful accounts. The allowance for doubtful accounts is reviewed quarterly, and is based on historical experience and known trends and uncertainties in account billing and collectability.

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 — As allowed by the amendments in ASU 2016-15, the Company elected to retrospectively apply the "Nature of Distribution" approach to classifying cash flows from its equity method investments. There were no other cash flow issues in ASU 2016-15 that impacted the Company's statement of cash flows presentation. The table below summarizes the impact on the year-to-date June 30, 2017 statement of cash flows of adopting ASU 2016-15 and ASU 2016-18.

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 — As of June 30, 2018, the Company has not updated any estimated provisional amounts previously reported and is still evaluating the impact of the Tax Cuts and Jobs Act of 2017. 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 outlined in Staff Accounting Bulletin No. 118.

Other ASUs

There were various other ASUs that became effective during the year-to-date June 30, 2018 period, which did not have a material impact on the Company's results of operations, financial position, cash flows, or disclosures.

ASC Topic 842, Leases — The Company established an ASC Topic 842 implementation team, which includes support from external experts, to evaluate and implement the standard. The Company has also established a timeline and selected a software solution for implementing the new standard. Management is currently in the diagnostic phase of determining the financial and business impacts of implementing the new standard, including identifying the lease population, reviewing a sample of lease agreements, and developing a preliminary assessment. Based on the information currently available from the diagnostic phase, management cannot yet determine the quantitative impact on the financial statements; however, the impact is expected to be material. Since management is continuing to evaluate the impact of ASC Topic 842, disclosures around preliminary assessments are subject to change.

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 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.

During the second quarter of 2018, the Company adjusted its purchase price allocation for new information obtained related to certain legal matters that were outstanding as of the 2017 Merger closing date, reflecting a $2.8 million increase in "Goodwill," a $4.5 million increase in "Accrued liabilities," and a $1.7 million decrease in "Deferred tax liabilities" in the September 9, 2017 opening balance sheet.

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 $103.3 million consisted of approximately $80.5 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 1.9% and 1.1% of consolidated total revenue, and 3.0% and 1.7% of consolidated net income attributable to Knight-Swift for the quarter and year-to-date June 30, 2018 periods, respectively. The acquired business also represented 1.5% of consolidated total assets as of June 30, 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 year-to-date June 30, 2018 period. This includes immaterial related expenses recorded during the second quarter of 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 8 — Income Taxes

Effective Tax Rate — The quarter-to-date June 30, 2018 and June 30, 2017 effective tax rates were 22.9% and 37.6%, respectively. The decrease was primarily a result of the Tax Cuts and Jobs Act of 2017. The Company recognized stock compensation deductions as a discrete item during the quarters ended June 30, 2018 and June 30, 2017.

The year-to-date June 30, 2018 and June 30, 2017 effective tax rates were 22.1% and 36.7%, 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 year-to-date June 30, 2018 period. The Company also recognized stock compensation deductions as a discrete item during the year-to-date June 30, 2017 period.

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 does not anticipate a decrease of unrecognized tax benefits during the next twelve months.

Interest and Penalties — Accrued interest and penalties related to unrecognized tax benefits as of June 30, 2018 and December 31, 2017 were approximately $0.6 million and $0.3 million, respectively.

Tax Examinations — Certain of the Company's subsidiaries are currently under examination by various state and federal 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 9 — Accounts Receivable Securitization

2015 RSA — 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. As of June 30, 2018, the Company's eligible receivables generally have high credit quality, as determined by the obligor's corporate credit rating.

Based on eligible receivables at June 30, 2018, the Company's borrowing base for the 2015 RSA was $297.1 million, while outstanding borrowings included in "Accounts receivable securitization" in the condensed consolidated balance sheets were $215.0 million. Outstanding letters of credit, which reduce the availability under the 2015 RSA, were $70.7 million at June 30, 2018. Based on eligible receivables at December 31, 2017, the Company's borrowing base for the 2015 RSA was $317.6 million, while outstanding borrowings included in "Accounts receivable securitization" in the condensed consolidated balance sheets were $305.0 million. There were no outstanding letters of credit related to the 2015 RSA at December 31, 2017.

As of June 30, 2018 and December 31, 2017, interest accrued on the 2015 RSA's aggregate principal balance at a rate of 2.7% 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 and $4.0 million related to the 2015 RSA during the quarter and year-to-date June 30, 2018 periods, respectively.

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 June 30, 2018. Collections on the underlying receivables by the Company are held for the benefit of Swift Receivables Company II, LLC ("SRCII") and the various purchasers and are unavailable to satisfy claims of the Company and its subsidiaries.

Refer to Note 14 for information regarding the fair value of the 2015 RSA.

Subsequent Event: 2018 RSA — On July 11, 2018, SRCII, a wholly-owned subsidiary of the Company, entered into the 2018 RSA, which further amends the 2015 RSA. The parties to the 2018 RSA are SRCII as the seller, Swift Transportation Services, LLC as the servicer, the various conduit purchasers, the various related committed purchasers, the various purchaser agents, the various letters of credit participants, and PNC Bank, National Association as the issuing bank for letters of credit and as administrator. Pursuant to the related Purchase and Sale Agreement and together with the 2018 RSA, the Company's receivable originator subsidiaries sell, on a revolving basis, undivided interests in all of their eligible accounts receivable to SRCII. In turn, SRCII sells a variable percentage ownership interest in the eligible accounts receivable to the various purchasers.

The following table summarizes the key differences between the 2018 RSA and the 2015 RSA (dollars in thousands):



	2018 RSA		2015 RSA
Effective date	July 11, 2018		December 10, 2015
Final maturity date	July 11, 2021		January 10, 2019
Borrowing capacity		$325,000		$400,000
Accordion option ⁽¹⁾		$175,000		$75,000
Unused commitment fee rate ⁽²⁾	20 to 40 basis points		35 basis points
Program fees on outstanding balances ⁽³⁾	one-month LIBOR + 80 to 100 basis points		one-month LIBOR + 90 basis points


(1)	The accordion option increases the maximum borrowing capacity, subject to participation of the purchasers.


(2)	The 2018 RSA commitment fee rate is based on the percentage of the maximum borrowing capacity utilized.


(3)	The 2018 RSA program fee is based on the Company's consolidated total net leverage ratio.

Note 10 — Purchase Commitments

As of June 30, 2018, the Company had outstanding commitments to acquire revenue equipment in 2018 of $506.6 million ($468.9 million of which were tractor commitments) and none thereafter. These purchases may be financed through any combination of operating leases, capital leases, debt, proceeds from sales of existing equipment, and cash flows from operations.

As of June 30, 2018, the Company had outstanding purchase commitments to acquire facilities and non-revenue equipment in the of remainder of 2018 of $4.2 million, in 2019 and 2020 of $3.3 million, in 2021 of $0.1 million, and none thereafter.

Factors such as costs and opportunities for future terminal expansions may change the amount of such expenditures.

Note 11 — 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 $87.9 million relating to the Company's outstanding legal proceedings as of June 30, 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.

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.

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 Court of Appeals and the parties have discussed settlement. There were no significant developments during the first half of 2018. Based on the above, the likelihood that a loss has been incurred is probable and estimable, and the loss has accordingly been accrued.

Utah Collective and Individual Arbitration

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 and the Company paid the settlement in the second quarter of 2018.


(1)	Individually and on behalf of all others similarly situated.

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. Since January 1, 2015, Swift has been fully insured on its medical benefits, subject to contributed premiums.

Note 12 — Share Repurchase Plans

On June 1, 2018, the Board approved the repurchase of up to $250.0 million of the Company's outstanding common stock (the "Knight-Swift Repurchase Plan"). With the adoption of the Knight-Swift Repurchase Plan, the Company terminated the $150.0 million repurchase plan approved by Swift's board of directors in February 2016 (the "Swift Repurchase Plan") which was prior to the 2017 Merger. When terminated, the Swift Repurchase Plan had approximately $62.9 million in remaining authorized purchases. During the quarter and year-to-date June 30, 2018 periods, the Company has purchased no shares of its common stock under the Knight-Swift Repurchase Plan, and as such $250.0 million in authorized purchases remained as of June 30, 2018. Subsequent to June 30, 2018, the Company repurchased 2.0 million shares for $66.1 million under the Knight-Swift Repurchase Plan, leaving $183.9 million available as of August 6, 2018.

Note 13 — 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-to-Date June 30,		Year-to-Date June 30,
	2018	2017	2018	2017
	(In thousands)
Basic weighted average common shares outstanding	178,451	80,520	178,307	80,416
Dilutive effect of equity awards	947	829	1,014	860
Diluted weighted average common shares outstanding	179,398	81,349	179,321	81,276
Anti-dilutive shares excluded from diluted earnings per share ⁽¹⁾	47	379	57	312


(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 common stock for the quarter and year-to-date June 30, 2018 periods and Knight's common stock for the quarter and year-to-date June 30, 2017 periods.

Note 14 — 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 June 30, 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 values of these financial instruments approximate their carrying values 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, as the Company's capital leases are structured to amortize in a manner similar to the depreciation of the underlying assets. All remaining balance sheet amounts excluded from the table below are not considered financial instruments subject to this disclosure.

Financial Assets — The carrying amounts and estimated fair values of the Company's financial assets are included in Note 5 for restricted investments, held to maturity and under "Recurring Fair Value Measurements" below for other investments.

Financial Liabilities —The following table presents the carrying amounts and estimated fair values of the Company's financial liabilities:



	June 30, 2018				December 31, 2017
	Carrying Value		Estimated Fair Value		Carrying Value		Estimated Fair Value

Term Loan, due October 2020 ⁽¹⁾	$	364,473	$	365,000	$	364,355	$	365,000
2015 RSA, due January 2019	215,000		215,000		305,000		305,000
Revolver, due October 2022	120,000		120,000		125,000		125,000


(1)	The carrying amount of the Term Loan is included in "Long-term debt, less current portion," and is net of $0.5 million and $0.6 million in deferred loan costs as of June 30, 2018 and December 31, 2017, respectively.

The estimated fair values of the Company's financial instruments as of June 30, 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, Held to Maturity — The estimated fair value of the Company's restricted investments, held to maturity, is based on quoted prices in active markets that are readily and regularly obtainable. See Note 5 for additional disclosures regarding restricted investments, held to maturity.

Term Loan — The estimated fair value of the Term Loan approximates the face value.

Securitization of Accounts Receivable — The Company's securitization of accounts receivable consists of borrowings outstanding pursuant to the 2015 RSA as of June 30, 2018 and December 31, 2017, as discussed in Note 9. The estimated fair value of the 2015 RSA approximates the face value.

(1)	The money market funds and debt securities are trading securities and are restricted to meet statutory requirements. The carrying value, included within "Other long-term assets" in the Company's condensed consolidated balance sheets, approximates the estimated fair value.

As of June 30, 2018 and December 31, 2017, there were no liabilities on the condensed consolidated balance sheets estimated at fair value that were measured on a recurring basis.

Nonrecurring Fair Value Measurements — As of June 30, 2018 and December 31, 2017, the Company had no major categories of liabilities estimated at fair value that were measured on a nonrecurring basis.

As of June 30, 2018, the Company had no major categories of assets estimated at fair value that were measured on a nonrecurring basis.

Note 16 — 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. Knight 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.

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 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 Knight-Swift's 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 16 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 through our nationwide network of terminals in the US and Mexico to serve customers throughout North America. In addition to operating the nation's largest fleet, we also have 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, excluding 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, excluding 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, excluding 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, amortization of intangible assets, interest expense, and non-driver employee compensation.

Recent Consolidated Results of Operations and Quarter-End Financial Condition

Trends and Outlook — During the second quarter of 2018, the US gross domestic product reached its highest level since 2014, and third-party forecasts indicate that it will continue to grow throughout 2018 and into 2019. Additionally, the US economy experienced a surge in its annual growth rate, primarily due to exporters shipping products earlier to avoid upcoming tariffs, as well as consumers spending more as a result of tax relief from the Tax Cuts and Jobs Act of 2017. Inventory levels across the US supply chain, which were in a surplus position in prior years, have recently become more balanced. The three main sources of freight demand, which are consumer spending, construction, and manufacturing, continue to show signs of growth.

Driver sourcing continues to be a headwind for the trucking industry, as, among other market factors, the national unemployment rate has reached a historical low, truck safety regulations have increased (including Electronic Logging Device ("ELD") regulations), and competition has increased for driving academy graduates and experienced hires.

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS — CONTINUED

Our financial results for the first half of 2018 were encouraging, as we saw the results of our continuing synergy efforts, as well as the continued impacts of favorable market dynamics in terms of freight demand and constrained trucking capacity. Given the strength in the freight market, as well as inflationary pressures related to driver wages, purchased transportation, and other costs, we expect to continue 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, share repurchases, 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 quarter and year-to-date June 30, 2018 results and prior periods may not be meaningful.

Comparison Between the Quarter-to-Date June 30, 2018 and 2017 Periods — The $73.4 million increase in net income attributable to Knight-Swift to $91.3 million during the second quarter of 2018 from $18.0 million in the second quarter of 2017 includes the following:


•	$32.3 million increase in Knight's operating income, primarily due to the Knight Trucking segment's results, which are discussed within "Segment Review," below. The increase in revenue, excluding fuel surcharge and intersegment transactions, was partially offset by an increase in driving associate-related costs.


•	$63.6 million in operating income from Swift's results for the second quarter of 2018, which included $10.3 million in amortization expense related to the intangible assets recorded in the 2017 Merger.

•

$16.4 million increase in income tax expense. The increase was primarily due to inclusion of Swift's results for the second quarter of 2018, and was partially offset by impacts from the Tax Cuts and Jobs Act of 2017, 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 to 22.9% in the second quarter of 2018 from 37.6% in the second quarter of 2017.


•	$7.1 million increase in interest expense, due to the inclusion of Swift's debt and capital lease balances during the second quarter of 2018.

Comparison Between the Year-to-Date June 30, 2018 and 2017 Periods — The $128.8 million increase in net income attributable to Knight-Swift to $161.7 million during the year-to-date June 30, 2018 period from $32.8 million during the same period last year includes the following:


•	$54.0 million increase in Knight's operating income, primarily due to the Knight Trucking segment's results, which are discussed within "Segment Review," below. The increase in revenue, excluding fuel surcharge and intersegment transactions, was partially offset by an increase in driving associate-related costs.


•	$112.9 million in operating income from Swift's results for the year-to-date June 30, 2018 period, which included $20.7 million in amortization expense related to the intangible assets recorded in the 2017 Merger.


•	$27.1 million increase in income tax expense. The increase was primarily due to inclusion of Swift's results for year-to-date June 30, 2018 period, and was partially offset by impacts from the Tax Cuts and Jobs Act of 2017. As such, the effective tax rate decreased to 22.1% in the the year-to-date June 30, 2018 period from 36.7% in the same period last year.


•	$13.8 million increase in interest expense, due to the inclusion of Swift's debt and capital lease balances during the year-to-date June 30, 2018 period.

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

Liquidity and Capital — During the year-to-date June 30, 2018 period, we generated $375.9 million in cash flows from operations and used $121.4 million for capital expenditures, net of equipment sales proceeds. During the year-to-date June 30, 2018 period, we returned $21.7 million to our stockholders in the form of quarterly dividends. We ended the quarter with $115.5 million in unrestricted cash and cash equivalents, $485.0 million in long-term debt (excluding the 2015 RSA and capital leases), and $5.4 billion of stockholders' equity. See discussion under "Liquidity and Capital Resources" and "Off-Balance Sheet Arrangements" 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, excluding fuel surcharge (and net of 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, excluding 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 percentage 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, excluding intersegment transactions, less purchased transportation expense) as a percentage of Knight's brokerage revenue, excluding 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 primarily 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.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS — CONTINUED

Comparison Between the Quarter-to-Date June 30, 2018 and 2017 Periods — The strong freight market and tight capacity supported increases in both contract and non-contract rates throughout the second quarter of 2018. Accordingly, the Knight Trucking segment's total revenue increased $74.4 million, which included $24.3 million in revenue from Abilene. Fuel surcharge revenue increased by $13.2 million, primarily due to higher average fuel prices. Average revenue per tractor increased 24.1% as a result of a 20.9% increase in revenue per loaded mile, excluding fuel surcharge and intersegment transactions, and a 3.9% improvement in miles per tractor, compared to the prior year quarter. As a result of these improvements and a 6.0% increase in average tractor count, revenue, excluding fuel surcharge and intersegment transactions, increased 31.5%.

Operating Ratio and Adjusted Operating Ratio improved by 750 and 690 basis points, respectively, 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 driving associates.

Comparison Between the Year-to-Date June 30, 2018 and 2017 Periods — The strong freight market and tight capacity supported increases in both contract and non-contract rates throughout the first half of 2018. Accordingly, the Knight Trucking segment's total revenue increased $110.7 million, which included $27.9 million in revenue from Abilene from March 17, 2018 through June 30, 2018. Fuel surcharge revenue increased by $20.3 million, primarily due to higher average fuel prices. Average revenue per tractor increased 21.0% as a result of an 18.6% increase in revenue per loaded mile, excluding fuel surcharge and intersegment transactions, and a 2.9% improvement in miles per tractor, compared to the prior year-to-date period. As a result of these improvements, revenue, excluding fuel surcharge and intersegment transactions, increased 23.4%.

Operating Ratio and Adjusted Operating Ratio improved by 720 and 750 basis points, respectively, primarily driven by the increases in revenue discussed above, partially offset by headwinds from driving associate-related costs, as noted above.

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 condensed 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 condensed consolidated income statements, and depreciation and amortization expense recorded in "Depreciation and amortization of property and equipment."

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS — CONTINUED

Comparison Between the Quarter-to-Date June 30, 2018 and 2017 Periods — The Knight Logistics segment's total revenue increased $23.6 million, which includes $1.0 million in revenue from Abilene. Brokerage revenue, excluding intersegment transactions, increased 45.4% in the Knight brokerage business, which is the largest component of the Knight Logistics segment. This was driven by a 26.6% increase in revenue per load and a 14.8% increase in load volumes.

Knight Logistics' Operating Ratio and Adjusted Operating Ratio improved by 40 and 40 basis points, respectively, primarily driven by the increases in revenue discussed above. Brokerage gross margin percentage for the quarter was slightly down year-over-year, as the revenue per load increase was offset by an increase in purchased transportation costs.

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.

Comparison Between the Year-to-Date June 30, 2018 and 2017 Periods — The Knight Logistics segment's total revenue increased $36.6 million, which includes $1.2 million in revenue from Abilene from March 17, 2018 through June 30, 2018. Brokerage revenue, excluding intersegment transactions, increased 35.3% in the Knight brokerage business, which is the largest component of the Knight Logistics segment. This was driven by a 27.7% increase in revenue per load and a 5.9% increase in Knight brokerage load volumes.

Knight Logistics' Operating Ratio and Adjusted Operating Ratio improved by 70 and 60 basis points, respectively, primarily driven by the increases in revenue discussed above. Brokerage gross margin percentage was relatively flat year-over-year, as the revenue per load increase was offset by an increase in purchased transportation costs.

Swift Segments

Swift Truckload, Swift Dedicated, and Swift Refrigerated — We generate revenue in the Swift trucking segments primarily through dry van, refrigerated, dedicated, drayage, flatbed, and cross-border service offerings. Refer to "Knight Trucking Segment," above for discussion of additional 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 cost of purchased transportation that we pay to third-party capacity providers (including rail providers), which is primarily variable and included in "Purchased transportation" in the condensed 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)	During the year-to-date June 30, 2018 period, the Swift trucking segments operated an average of 14,717 tractors, of which 11,368 were company-owned tractors. The average ages of Swift's tractor and trailer fleets were 2.5 years and 8.1 years, respectively.

Swift Truckload, Swift Dedicated, and Swift Refrigerated — Profitability within the Swift trucking segments has been improving, but is 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 during the first half of 2018, 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 Truckload — For the quarter and year-to-date June 30, 2018 periods, average revenue per tractor in our Swift Truckload segment was positively affected by improvements in both our contract and non-contract rates, partially offset by the segment's utilization. Over the last several quarters we have emphasized our focus on improving revenue per tractor, which has led to a change in our freight mix, a shorter length of haul, and fewer miles per tractor. The Swift Truckload segment showed meaningful improvement in Operating Ratio, Adjusted Operating Ratio, and Adjusted Operating Income.


•	Swift Dedicated — For the quarter and year-to-date June 30, 2018 periods, average revenue per tractor within our Swift Dedicated segment was positively affected by improvements in contract rates. The Swift Dedicated segment showed improvements in both Operating Ratio and Adjusted Operating Ratio.

•

Swift Refrigerated — For the quarter and year-to-date June 30, 2018 periods, average revenue per tractor within our Swift Refrigerated segment was supported by increases in contract rates, but was offset by challenges within its utilization. We have identified opportunities for improvement and have a team working on solutions that we believe will support improved results beginning in the second half of 2018.

Swift Intermodal — For the quarter and year-to-date June 30, 2018 periods, we saw improvements in the Swift Intermodal segment's revenue, excluding fuel 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 improvements in revenue, excluding fuel surcharge, and improved drayage efficiencies. We are focused on improving Swift Intermodal by right-sizing its cost infrastructure, increasing container turns, and driving operational efficiencies.

Results of Operations — Consolidated Operating and Other Expenses

Consolidated Operating Expenses

The following tables present certain operating expenses from our condensed consolidated income statements, including each operating expense as a percentage of total revenue and as a percentage of revenue, excluding 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, excluding fuel surcharge is a better measure for analyzing many of our expenses and operating metrics.



	Quarter-to-Date June 30,						Year-to-Date June 30,						QTD 2018 vs.		YTD 2018 vs.
	2018			2017			2018			2017			QTD 2017		YTD 2017
	(Dollars in thousands)												Increase (Decrease)
Salaries, wages, and benefits	$	371,405		$	79,944		$	733,078		$	162,454		364.6	%	351.3	%
% of total revenue	27.9		%	29.3		%	28.2		%	29.8		%	(140	bps)	(160	bps)
% of revenue, excluding fuel surcharge	31.8		%	32.4		%	32.0		%	33.0		%	(60	bps)	(100	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 represent the largest component of salaries, wages, and benefits expense.

Several ongoing market factors have reduced the pool of available driving associates, contributing to a challenging driver sourcing market, which we believe will continue. Having a sufficient number of qualified driving associates is our biggest headwind, although we continue to seek ways to attract and retain qualified driving associates, including heavily investing in our recruiting efforts, our driving academies, and technology and terminals that improve the experience of driving associates. As a result of the tight market for qualified driving associates, we granted pay increases to our driving associates during the first half of 2018, as supported by increases in customer rates. We expect driving associate pay to remain inflationary, which could result in additional driving associate pay increases in the future.


•	Comparison Between the Quarter-to-Date June 30, 2018 and 2017 Periods — The $291.5 million increase in consolidated salaries, wages, and benefits includes $272.7 million of expense from Swift's results for the second quarter of 2018. Further, Knight's salaries, wages, and benefits expense increased $18.8 million, which included $7.4 million in expense from Abilene's results.

•

Comparison Between the Year-to-Date June 30, 2018 and 2017 Periods — The $570.6 million increase in consolidated salaries, wages, and benefits includes $542.4 million of expense from Swift's results for the year-to-date June 30, 2018 period. Further, Knight's salaries, wages, and benefits expense increased $28.2 million, which included $8.6 million in expense from Abilene's results from March 17, 2018 to June 30, 2018.

Knight's quarter and year-to-date increases in salaries, wages, and benefits expense were primarily related to Knight's driving associate-related costs, which were affected by driving associate pay increases and an increase in company miles.

% of revenue, excluding fuel surcharge	13.9		%	13.7		%	13.4		%	14.0		%	20	bps	(60	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, or 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 Quarter-to-Date June 30, 2018 and 2017 Periods — The $129.3 million increase in consolidated fuel expense includes $112.8 million of expense from Swift's results for the second quarter of 2018. Knight's fuel expense increased $16.5 million, which includes $5.2 million in expense from Abilene's results. Miles driven by Knight's company driving associates increased and US diesel fuel prices were higher overall in the second quarter of 2018 at $3.19 per gallon, compared to the second quarter of 2017 at $2.55 per gallon.

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 continue 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 Quarter-to-Date June 30, 2018 and 2017 Periods — The $67.7 million increase in consolidated operations and maintenance expense includes $64.5 million of expense from Swift's results for the second quarter of 2018. Knight's operations and maintenance expense increased $3.2 million, which includes $2.3 million in expense from Abilene's results.

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. In future periods, Swift's higher self-retention limits may cause our consolidated insurance and claims expense to fluctuate more.

Depreciation relates primarily to our owned tractors, trailers, buildings, 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 Quarter-to-Date June 30, 2018 and 2017 Periods — The $66.5 million increase in consolidated depreciation and amortization of property and equipment includes $64.0 million of expense from Swift's results for the second quarter of 2018. Knight's depreciation and amortization of property and equipment increased $2.5 million, which was attributed to Abilene's second quarter 2018 results.

•

Comparison Between the Year-to-Date June 30, 2018 and 2017 Periods — The $130.8 million increase in consolidated depreciation and amortization of property and equipment includes $128.4 million of expense from Swift's results for the year-to-date June 30, 2018 period. Knight's depreciation and amortization of property and equipment increased $2.4 million, which was attributed Abilene's results from March 17, 2018 through June 30, 2018.

Amortization of intangibles primarily relates to intangible assets identified with the 2017 Merger. See Note 4 and Note 7 in Part I, Item 1, of this Quarterly Report for further details regarding the Company's intangible assets.

The $10.6 million quarter-to-date increase and $20.9 million year-to-date 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 increase is attributed to amortization of the intangible assets associated with the Abilene Acquisition.

•	Comparison Between the Quarter-to-Date June 30, 2018 and 2017 Periods — The $46.5 million increase in consolidated rental expense includes $46.1 million of expense from Swift's results for the second quarter of 2018. Knight's rental expense increased $0.4 million, primarily due to Abilene's second quarter 2018 results.


•	Comparison Between the Year-to-Date June 30, 2018 and 2017 Periods — The $98.0 million increase in consolidated rental expense includes $97.7 million of expense from Swift's results for the year-to-date June 30, 2018 period. Knight's rental expense increased by $0.3 million, primarily due to Abilene's results from March 17, 2018 through June 30, 2018.

Quarter and year-to-date consolidated rental expense as a percentage of consolidated revenue, excluding fuel surcharge increased, as Swift historically obtained a larger portion of its equipment through operating leases, as compared to Knight.

% of revenue, excluding fuel surcharge	28.7		%	23.6		%	28.8		%	23.8		%	510	bps	500	bps

Purchased transportation expense is comprised of payments to independent contractors in our trucking operations, as well as 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 as 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.

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 in the second half of 2018.

•

Comparison Between the Quarter-to-Date June 30, 2018 and 2017 Periods — The $277.4 million increase in consolidated purchased transportation expense includes $253.3 million of expense from Swift's results for the second quarter of 2018. Knight's purchased transportation expense increased by $24.1 million, which includes Abilene's results of $2.7 million. The remaining increase in Knight's purchased transportation expense was almost entirely attributed to the Knight Logistics segment.

Interest expense — Interest expense is comprised of debt and capital lease interest expense as well as amortization of deferred loan costs. The $7.1 million quarter-to-date and $13.8 million year-to-date increases in consolidated interest expense are attributed to the inclusion of Swift's debt and capital lease balances during the quarter and year-to-date June 30, 2018 periods.

Income tax expense — In addition to the discussion below, Note 8 in Part I, Item 1 of this Quarterly Report provides further analysis related to income taxes.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS — CONTINUED

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 income, 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 quarter and year-to-date June 30, 2018 results and prior periods may not be meaningful.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS — CONTINUED

Liquidity and Capital Resources

Sources of Liquidity

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



Source	June 30, 2018
	(In thousands)
Cash and cash equivalents, excluding restricted cash	$	115,494
Availability under Revolver, due October 2022 ⁽¹⁾	643,380
Availability under 2015 RSA, due January 2019 ⁽²⁾	11,375
Total unrestricted liquidity	$	770,249
Cash and cash equivalents – restricted ⁽³⁾	52,818
Restricted investments, held to maturity, amortized cost ⁽³⁾	21,498
Total liquidity, including restricted cash and restricted investments	$	844,565


(1)	As of June 30, 2018, we had $120.0 million in borrowings under our $800.0 million Revolver. We additionally had $36.6 million in outstanding letters of credit (discussed below), leaving $643.4 million available under the Revolver.


(2)	Based on eligible receivables at June 30, 2018, our borrowing base for the 2015 RSA was $297.1 million, while outstanding borrowings were $215.0 million, gross of deferred loan costs. We additionally had $70.7 million in outstanding letters of credit (discussed below), leaving $11.4 million available under the 2015 RSA.

(3)

Restricted cash and restricted investments are primarily held by our captive insurance companies for claims payments. "Cash and cash equivalents – restricted" consists of $50.7 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 $2.1 million is included in "Other long-term assets" 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 2018 RSA, and availability under the Revolver will be sufficient to fund our expected capital expenditures for at least the next twelve months.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS — CONTINUED

Principal and Interest Payments — As of June 30, 2018, we had material debt and capital lease obligations of $858.7 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 and our 2015 RSA, 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 or under the 2015 RSA. 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, common stock prices, general economic and market conditions, as well as Board approval, we may repurchase shares of our outstanding common stock. As of June 30, 2018, the Company has $250.0 million remaining under the Knight-Swift Share Repurchase Plan, which replaced the $62.9 million remaining under the Swift Share Repurchase Plan. Additional details are discussed in Note 12 in Part I, Item 1 of this Quarterly Report.

Working Capital

As of June 30, 2018 and December 31, 2017, we had a working capital surplus of $300.1 million and $313.7 million, respectively.

Material Debt Agreements

As of June 30, 2018, we had $858.7 million in material debt obligations at the following carrying values:


•	$364.5 million: Term Loan, due October 2020, net of $0.5 million deferred loan costs


•	$215.0 million: 2015 RSA outstanding borrowings, due January 2019


•	$158.7 million: Capital lease obligations


•	$120.0 million: Revolver, due October 2022


•	$0.5 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

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 and year-to-date June 30, 2018 periods, we terminated various leases associated with revenue equipment that had an originating aggregate value of $121.3 million and $191.8 million, respectively.

Cash Flow Analysis



	Year-to-Date June 30,						Change
	2018			2017
	(In thousands)
Net cash provided by operating activities	$	375,912		$	120,914		$	254,998
Net cash used in investing activities	(232,564		)	(16,345		)	(216,219		)
Net cash used in financing activities	(126,769		)	(23,795		)	(102,974		)

Net Cash Provided by Operating Activities

Comparison Between the Year-to-Date June 30, 2018 and 2017 Periods — The $255.0 million increase in net cash provided by operating activities was primarily due to the $166.9 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, adjusted for the non-cash increase in depreciation and amortization of property and equipment of $128.4 million pertaining to Swift's results for the year-to-date June 30, 2018 period. This was partially offset by a $13.2 million increase in interest payments due to the inclusion of Swift's debt and capital lease balances during the year-to-date June 30, 2018 period, as well as timing differences in our working capital.

Net Cash Used in Investing Activities

Comparison Between the Year-to-Date June 30, 2018 and 2017 Periods — The $216.2 million increase in net cash used in investing activities was due to $101.6 million in cash paid to acquire Abilene, net of cash acquired from Abilene's balance sheet as of March 16, 2018, as well as a $98.8 million increase in net cash capital expenditures.

Net Cash Provided by (Used in) Financing Activities

Comparison Between the Year-to-Date June 30, 2018 and 2017 Periods — Net cash used in financing activities increased by $103.0 million, which was primarily due to $90.0 million of repayments, net of borrowings, on the 2015 RSA, and an increase in dividends paid of $11.8 million.

Contractual Obligations

"Liquidity and Capital Resources," above, includes details regarding changes in our contractual obligations table during the year-to-date June 30, 2018 period. Aside from these items, there were no material changes to the contractual obligations table, which was included in our 2017 Annual Report.

Off Balance Sheet Arrangements

Information about our off balance sheet arrangements is included in Note 10 of the notes to our condensed consolidated financial statements, included in Part I, Item 1 of this Quarterly Report, which is incorporated by reference herein. See also "Contractual Obligations," above.

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 of 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 of 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 year-to-date June 30, 2018 period.


•	Note 3 for recently issued accounting pronouncements, not yet adopted by the Company as of June 30, 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 2.88% as of June 30, 2018) and fixed rate equipment lease financing. Assuming the level of borrowings as of June 30, 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 US, as reported by the US Department of Energy, increased from an average of $2.55 per gallon for the quarter-to-date June 30, 2017 period to an average of $3.19 per gallon for the quarter-to-date June 30, 2018 period. The weekly average diesel price per gallon in the US increased from an average of $2.56 per gallon for the year-to-date June 30, 2017 period to an average of $3.10 per gallon for the year-to-date June 30, 2018 period. 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 June 30, 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 11 of the notes to our condensed consolidated financial statements, included in Part I, Item 1, of this Quarterly Report for the period ended June 30, 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

While we attempt to identify, manage, and mitigate risks and uncertainties associated with our business, some level of risk and uncertainty will always be present. Our 2017 Annual Report and our Quarterly Report for the quarterly period ended March 31, 2018, in the section of each document entitled, "Item 1A. Risk Factors" describes some of the risks and uncertainties associated with our business.
