KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 — Introduction and Basis of Presentation

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

Description of Business

Knight-Swift is a transportation solutions provider, headquartered in Phoenix, Arizona. During the quarter ended March 31, 2020, the Company operated an average of 18,462 tractors (comprised of 16,339 company tractors and 2,123 independent contractor tractors) and 57,716 trailers within the Trucking segment. Additionally, the Company operated an average of 601 tractors and 9,856 containers in the Intermodal segment. The Company's three reportable segments are Trucking, Logistics, and Intermodal.

Basis of Presentation

The condensed consolidated financial statements and footnotes included in this Quarterly Report include the accounts of Knight-Swift Transportation Holdings Inc. and its subsidiaries and should be read in conjunction with the consolidated financial statements and footnotes included in Knight-Swift's 2019 Annual Report. 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.

Changes in Presentation

Changes in presentation associated with adopting accounting pronouncements are included in Note 2.

Beginning in the second quarter of 2019, the Company presents fuel surcharge revenue generated within only its Trucking segment within "Trucking fuel surcharge" in the condensed consolidated statements of comprehensive income. Fuel surcharge revenue generated within the remaining segments is included in "Revenue, excluding trucking fuel surcharge." Prior period amounts have been reclassified to align with the current period presentation.

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. These factors typically lead to lower operating profitability, as compared to 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 length of the holiday season (consumer shopping days between Thanksgiving and Christmas). However, cyclical changes in the trucking industry, including imbalances in supply and demand, can override the seasonality faced in the industry.

Impact of COVID-19

During the first quarter of 2020, COVID-19 became a global pandemic, which triggered a significant downturn in the global economy. The Company continues to operate its business through the COVID-19 pandemic and has taken many additional precautions to ensure the safety of its employees, customers, vendors, and the communities in which it operates. As part of the Company's efforts to safeguard its employees and promote business continuity, management has taken additional precautions to enhance the sanitization process of its equipment and properties, increase the social distancing of its employees by working remotely where possible, and provide driving associates with essential

provisions and enhanced bonus opportunities while they are over the road delivering freight to Knight-Swift's customers. During the first quarter of 2020, we incurred $2.3 million of incremental costs directly associated with COVID-19.

There are various uncertainties that have arisen from the COVID-19 pandemic. While management is continuing to monitor the impact of the pandemic on Knight-Swift, including its employees, customers, independent contractors, stockholders, and other business partners and stakeholders, it is difficult to predict the impact that the pandemic will have on future results of its operations, financial position, and liquidity. This has caused some uncertainties around various accounting estimates. Due to these uncertainties, our accounting estimates may change, as management's assessment of the impacts of the COVID-19 pandemic continues to evolve.

Note 2 — Recently Adopted Accounting Pronouncements

ASU 2016-13: Financial Instruments – Credit Losses (Topic 326) — Measurements of Credit Losses on Financial Instruments

Summary of the Standard — In June 2016, the FASB issued ASU 2016-13, which, in addition to several clarifying ASUs, established the new ASC Topic 326, Financial Instruments — Credit Losses ("CECL"). The new CECL standard amends the FASB's guidance on the impairment of financial instruments. Specifically, it adds the CECL impairment model to GAAP which is based on expected losses rather than incurred losses. This is intended to result in more timely recognition of such losses. Under the new CECL standard, an entity recognizes as an allowance its estimate of lifetime expected credit losses. The new CECL standard is also intended to reduce the complexity of GAAP by decreasing the number of credit impairment models that entities use to account for debt instruments. Further, the new CECL standard makes targeted changes to the impairment model for available-for-sale debt securities and moves the guidance from ASC Topic 320 to ASC Subtopic 326-30. For public business entities, the new standard was effective for annual and interim reporting periods beginning after December 15, 2019. For most debt instruments, entities are required to adopt the new CECL standard using a modified retrospective approach, meaning that entities will record a cumulative-effect adjustment to equity as of the beginning of the first reporting period in which the guidance is effective.

Practical Expedient — As permitted under ASU 2016-13 (and related ASUs), management elected to apply the collateral dependent financial asset practical expedient which allows entities to measure the expected credit losses for the financial asset by comparing the amortized cost basis with the fair value of the collateral at the reporting date, rather than using the fair value of the financial asset.

Current Period Impact of Adoption — The Company adopted ASC Topic 326 on January 1, 2020 using the modified retrospective approach. Upon adoption of the standard management assessed the potential impact of the CECL model on each type of the Company's financial assets and determined that there was no material impact on the Company's financial statements or accounting policies.

ASU 2018-15: Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

Summary of the Standard — In August 2018, the FASB issued ASU 2018-15, which amends ASC Subtopic 350-40 to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement that is a service contract ("Service CCA"). The amendments in ASU 2018-15 align the accounting for costs incurred to implement a Service CCA with previously codified guidance on capitalizing costs associated with developing or obtaining internal-use software.

Specifically, the ASU amends ASC Subtopic 350-40 to include in its scope implementation costs incurred with a Service CCA. This addition clarifies that a customer should apply the guidance from ASC Paragraph 350-40-25 to determine which stage the project is in before assessing whether implementation costs should be capitalized in a Service CCA that is considered a service contract. These capitalized items should be recorded within the same balance sheet line item as a prepayment for any fees.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) — CONTINUED

Any capitalized costs from the Service CCA should be expensed over the term of the hosting arrangement, which includes the noncancelable period and any options to extend that are reasonably certain to be exercised and recorded in the same line item as fees associated with the hosting element of the arrangement. The amendments in this ASU were effective for public business entities for fiscal years beginning after December 15, 2019 and could be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption.

Current Period Impact of Adoption — The Company adopted the amendments in ASU 2018-15 on January 1, 2020 and elected to apply the amendments on a prospective basis to implementation costs incurred after the date of adoption. Upon review of the Service CCA's entered into during the first quarter of 2020, management has determined that adoption of the amendments has not had a material impact on the Company's financial statements and related accounting policies.

ASU 2017-04: Intangibles – Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment

Summary of the Standard — In January 2017, the FASB issued ASU 2017-04, which amends ASC Topic 350 by simplifying the goodwill impairment test. The amendments in this ASU are intended to simplify subsequent measurement of goodwill. The key amendment in the ASU eliminates Step 2 from the goodwill impairment test, in which entities measured a goodwill impairment loss by comparing the implied fair value to the carrying amount of a reporting unit's goodwill. Instead, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value with the carrying amount of a reporting unit and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The amendments also require companies to disclose the amounts of goodwill allocated to each reporting unit with a zero or negative carrying amount of assets. The amendments were effective for public business entities for fiscal years beginning after December 15, 2019 and should be applied on a prospective basis.

Current Period Impact of Adoption — The Company adopted the amendments in ASU 2017-14 on January 1, 2020 on a prospective basis. Management has updated the Company's accounting policy to incorporate the amendments in the ASU and has included the revised disclosure requirements below.

Refer to Note 7 for disclosures about the Company's goodwill balances.

Accounting Policy Update

Goodwill — Management evaluates goodwill on an annual basis as of June 30^th, or more frequently if indicators of impairment exist. The Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company conducts a quantitative goodwill impairment test. Management estimates the fair values of its reporting units using a combination of the income and market approaches. If the carrying amount of a reporting unit exceeds the fair value, then management will recognize an impairment loss of the same amount. This loss is only limited to the total amount of goodwill allocated to that reporting unit.

Other ASUs

There were various other ASUs that became effective during the quarter ended March 31, 2020, which did not have a material impact on the Company's results of operations, financial position, cash flows, or disclosures.

Note 4 — Acquisition

On January 1, 2020, pursuant to a stock purchase agreement (the "SPA") the Company acquired 100.0% of the equity interests of a warehousing-related company (the "Warehousing Co.") with locations throughout the Central US.

The total purchase price consideration of $66.9 million consisted of approximately $48.2 million in cash to the sellers at closing, and contingent consideration consisting of three additional annual payments of up to $8.1 million each (or $24.3 million in total), representing the maximum possible annual deferred payments to the sellers based on Warehousing Co.'s earnings before interest and taxes ("EBIT") for each of the calendar years ending December 31, 2020, December 31, 2021, and the annualized six-month period ending June 30, 2022. In order to estimate Warehousing Co.'s future performance, the Company utilized the Monte Carlo simulation method using certain inputs, including Warehousing Co.'s forecasted EBIT, discount rate, dividend yields, expected volatility, and expected stock returns during the above measurement periods. Based on the above inputs, the present value of the total contingent consideration was estimated to equal $18.7 million as of January 1, 2020. The Company funded the acquisition through cash-on-hand and borrowing on the Revolver on the date of the transaction. At closing, $6.8 million of the cash consideration was placed in escrow to secure certain of the sellers' indemnification obligations and remains subject to further adjustments.

The SPA 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 SPA contains customary representations, warranties, covenants, and indemnification provisions.

The goodwill recognized represents expected synergies from combining the operations of Warehousing Co. with the Company, including enhanced service offerings, 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 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 effective tax rate was 27.2% for the first quarter of 2020, compared to 24.0% for the first quarter of 2019. The Company recognized discrete items relating to foreign currency fluctuations and stock compensation deductions during the quarter ended March 31, 2020.

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 — Management believes it is reasonably possible that a decrease of up to $1.0 million in unrecognized tax benefits relating to federal deductions may be necessary within the next twelve months.

Interest and Penalties — Accrued interest and penalties related to unrecognized tax benefits was approximately $0.4 million for the periods ended March 31, 2020 and December 31, 2019.

Tax Examinations — The Company is currently under examination by the IRS for the 2012 tax year and management does not expect any adjustments that would have a material impact on the Company's effective tax rate. Certain of the Company's subsidiaries are also currently under examination by various state jurisdictions for tax years ranging from 2013 to 2018. 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 2014 remain subject to examination.

Note 9 — Accounts Receivable Securitization

The 2018 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 receivable originator subsidiaries sell, on a revolving basis, undivided interests in all of their eligible accounts receivable to Swift Receivables Company II, LLC ("SRCII") who in turn sells a variable percentage ownership in those receivables to the various purchasers. The Company's eligible receivables are included in "Trade receivables, net of allowance for doubtful accounts" in the condensed consolidated balance sheets. As of March 31, 2020, the Company's eligible receivables generally have high credit quality, as determined by the obligor's corporate credit rating.

The 2018 RSA is subject to fees, various affirmative and negative covenants, representations and warranties, and default and termination provisions customary for facilities of this type. The Company was in compliance with these covenants as of March 31, 2020. Collections on the underlying receivables by the Company are held for the benefit of SRCII and the various purchasers and are unavailable to satisfy claims of the Company and its subsidiaries.

Purchase Commitments

As of March 31, 2020, the Company had outstanding commitments to purchase revenue equipment of $405.7 million in the remainder of 2020 ($274.0 million of which were tractor commitments) and none thereafter. These purchases may be financed through any combination of operating leases, finance leases, debt, proceeds from sales of existing equipment, and cash flows from operations.

As of March 31, 2020, the Company had outstanding commitments to purchase facilities and non-revenue equipment of $6.0 million in the remainder of 2020, $1.2 million in the two-year period 2021 through 2022, $0.2 million in the two-year period 2023 through 2024, and none thereafter. Factors such as costs and opportunities for future terminal expansions may change the amount of such expenditures.

TRP Commitments

Since 2003, Knight has entered into partnership agreements with entities that make privately-negotiated equity investments. In these agreements, Knight committed to invest in return for an ownership percentage. During the first quarter of 2020, Knight entered into a $20.0 million commitment to invest in the newly formed TRP Capital Partners V, LP with the entire commitment outstanding as of March 31, 2020. There were no other material changes related to the previously disclosed TRP commitments during the quarter ended March 31, 2020.

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 included in "Accrued liabilities" in the condensed consolidated balance sheets. The Company has recorded an aggregate accrual of approximately $27.7 million, relating to the Company's outstanding legal proceedings as of March 31, 2020.

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.

Share Repurchase Plan		Quarter Ended March 31, 2020
Board Approval Date	Authorized Amount	Shares	Amount
	(in thousands)
May 30, 2019 ¹	$250,000	1,139	$	34,630

1 $199.0 million and $233.6 million remained available under the 2019 Knight-Swift Share Repurchase Plan as of March 31, 2020 and December 31, 2019, respectively.

Note 13 — Weighted Average Shares Outstanding

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

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

	Quarter Ended March 31,
	2020	2019
	(In thousands)
Basic weighted average common shares outstanding	170,617	172,971
Dilutive effect of equity awards	665	637
Diluted weighted average common shares outstanding	171,282	173,608
Anti-dilutive shares excluded from diluted earnings per share ¹	256	997

1 Shares were excluded from the dilutive-effect calculation because the outstanding awards' exercise prices were greater than the average market price of the Company's common stock for the periods presented.

Note 15 — Information by Segment and Geography

Segment Information

The Company has three reportable segments: Trucking, Logistics, and Intermodal, as well as the non-reportable segments, discussed below. Based on how economic factors affect the nature, amount, timing, and uncertainty of revenue or cash flows, the Company disaggregates revenues by reportable segment for the purposes of applying the ASC Topic 606 guidance.

Trucking

The Trucking segment is comprised of irregular route and dedicated, refrigerated, expedited, flatbed, and cross-border operations.

Logistics

The Logistics segment is primarily comprised of brokerage and other freight management services.

Intermodal

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

Non-reportable

The non-reportable segments include support services provided to the Company's customers and independent contractors (including repair and maintenance shop services, equipment leasing, warranty services, and insurance), trailer parts manufacturing, warehousing, and certain driving academy activities, as well as certain corporate expenses (such as legal settlements and accruals, certain impairments, and amortization of intangibles related to the 2017 Merger and various acquisitions).

Intersegment Eliminations

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

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

	Quarter Ended March 31,
	2020			2019
Revenue:	(In thousands)
Trucking	$	919,061		$	973,245
Logistics	79,198			88,952
Intermodal	94,731			116,367

Additionally, long-lived assets on the Company's foreign subsidiary balance sheets were less than 5.0% of consolidated total assets as of March 31, 2020 and December 31, 2019.

Note 16 — Fair Value Measurement

ASC Topic 820, Fair Value Measurements and Disclosures, requires that the Company disclose estimated fair values for its financial instruments. The estimated fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market for the asset or liability. Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Changes in assumptions could significantly affect these estimates. Because the fair value is estimated as of March 31, 2020 and December 31, 2019, the amounts that will actually be realized or paid at settlement or maturity of the instruments in the future could be significantly different.

The estimated fair values of the Company's financial instruments 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.

24

Table of Contents Glossary of Terms

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) — CONTINUED

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.

Transportation Resource Partners — The estimated fair value of the Company's investments with Transportation Resource Partners are privately negotiated equity investments. The carrying amount of these investments approximates the fair value.

Equity Securities — The estimated fair value of the Company's investments in equity securities is based on quoted prices in active markets that are readily and regularly obtainable.

Debt Instruments and Leases — For notes payable under the Revolver and the Term Loan, fair value approximates the carrying value due to the variable interest rate. The carrying value of the 2018 RSA approximates fair value, as the underlying receivables are short-term in nature and only eligible receivables (such as those with high credit ratings) are qualified to secure the borrowed amounts. For finance and operating leases, the carrying value approximates the fair value, as the Company's finance and operating leases are structured to amortize in a manner similar to the depreciation of the underlying assets.

Other — Cash and cash equivalents, restricted cash, net accounts receivable, income tax refund receivable, and accounts payable represent financial instruments for which the carrying amount approximates fair value, as they are short-term in nature. These instruments are accordingly excluded from the disclosures below. All remaining balance sheet amounts excluded from the below are not considered financial instruments, subject to this disclosure.

The following table presents the carrying amounts and estimated fair values of the Company's major categories of financial assets and liabilities:

Executive Summary

Impact of COVID-19

We continue to operate our business through the COVID-19 pandemic and have taken many additional precautions to ensure the safety of our employees, customers, vendors, and the communities in which we operate. Our diverse customer base has permitted us to balance our truckload capacity between customers with significant declines in volumes and those experiencing surges in demand for essential consumer products. We believe we are well-prepared for the sustainability of our business from a balance sheet perspective with a very conservative debt balance and a meaningful level of available liquidity, coupled with a conservative, cost-minded culture. We are fortunate that our multiple brands and diverse operating model have enabled us to rapidly adapt to the ever-changing economic environment. We believe we are well-positioned to navigate through these unprecedented times, while continuing to support our customers and ultimately the greater economy.

The COVID-19 pandemic, and efforts to contain it, has significantly affected the economy and the everyday lives of people around the world. Trucking has always been an essential service, which has become increasingly apparent as we partner with our customers to deliver vital goods to consumers throughout North America during these trying times. As part of our efforts to safeguard our employees and promote business continuity, we have taken many additional precautions to enhance the sanitization process of our equipment and properties, increase the social distancing of our employees by working remotely where possible, and provide our driving associates with essential provisions and enhanced bonus opportunities while they are over the road delivering freight for our customers. During the first quarter of 2020, we invested approximately $2.3 million of incremental expenses associated with our drivers and terminal employees to ensure safety and that communities received essential products. We expect to incur costs of a similar nature in the second quarter of 2020.

Refer to Part II, Item 1A "Risk Factors" of this Quarterly Report for more discussion about potential risks and uncertainties surrounding the COVID-19 pandemic that may impact our business, results of operations, or financial condition.

Company Overview

Knight-Swift Transportation Holdings Inc. is North America's largest truckload carrier and a provider of transportation solutions, headquartered in Phoenix, Arizona. The Company provides multiple truckload transportation, intermodal, and logistics services using a nationwide network of business units and terminals in the US and Mexico to serve customers throughout North America. In addition to its truckload services, Knight-Swift also contracts with third-party capacity providers to provide a broad range of shipping solutions to its customers while creating quality driving jobs for our driving associates and successful business opportunities for independent contractors. Our three reportable segments are Trucking, Logistics, and Intermodal. Additionally, we have various non-reportable segments. Refer to Note 15 in Part I, Item 1 of this Quarterly Report for descriptions of our segments.

Our objective is to operate our business with industry-leading margins and growth while providing safe, high-quality, cost-effective solutions for our customers.

Revenue

• Our trucking services include irregular route and dedicated, refrigerated, expedited, flatbed, and cross-border transportation of various products, goods, and materials for our diverse customer base. We primarily generate revenue by transporting freight for our customers through our Trucking segment.

• 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 and freight management services. Revenue in our brokerage and intermodal operations is generated through our Logistics and Intermodal segments.

• Our non-reportable segments include support services provided to our customers and independent contractors (including repair and maintenance shop services, equipment leasing, warranty services, and insurance), trailer parts manufacturing, warehousing, and certain driving academy activities, as well as certain corporate expenses

(such as legal settlements and accruals, certain impairments, and amortization of intangibles related to the 2017 Merger and various acquisitions).

• 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 segment.

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.

Operating Statistics — We measure our consolidated and segment results through certain operating statistics, which are discussed under "Results of Operations — Segment Review — Operating Statistics," below. Our results are affected by various economic, industry, operational, regulatory, and other factors, which are discussed in detail in "Part I, Item 1A. Risk Factors," in our 2019 Annual Report, and supplemented in Part II, Item 1A of this Quarterly Report, as well as in various disclosures in our press releases, stockholder reports, and other filings with the SEC.

Fuel surcharge revenue generated within the remaining segments is included in "Revenue, excluding trucking fuel surcharge." Prior period amounts have been reclassified to align with the current period presentation.

2 Adjusted Net Income Attributable to Knight-Swift, Adjusted EPS, and Adjusted Operating Ratio are non-GAAP financial measures and should not be considered alternatives, or superior to, the most directly comparable GAAP financial measures. However, management believes that presentation of these non-GAAP financial measures provides useful information to investors regarding the Company's results of operations. Adjusted Net Income Attributable to Knight-Swift, Adjusted EPS, and Adjusted Operating Ratio are reconciled to the most directly comparable GAAP financial measures under "Non-GAAP Financial Measures," below.

Market Trends and Company Performance

Trends and Outlook — The truckload freight environment remains competitive, amongst the impacts of the COVID-19 global pandemic. Evidence of capacity rationalization is mounting in the truckload industry, including impacts from trucking company business failures, lower Class 8 new truck orders, further weakening of Class 8 used tractor values, growing Class 8 used inventories, and contraction in trucking employment. Capacity rationalization has continued to accelerate, causing lower gains on sale of used revenue equipment in the trucking industry, which we have experienced as well. We expect that the uncertainty around the freight environment will continue throughout a large portion of the year.

As a result of the COVID-19 pandemic, the national unemployment rate began to rise, ending the first quarter of 2020 at 4.4%. The unemployment rate is expected to steadily rise throughout the majority of 2020. Driver sourcing generally continues to be a headwind for the trucking industry. Ongoing competition for driving academy graduates and experienced hires, as well as increased safety regulations, tend to hamper driver sourcing efforts throughout the industry. Given the overall uncertainties in the freight market, we anticipate that drivers may prefer to seek employment from larger trucking companies that are more financially secure than others. This may positively position our company in the driver sourcing environment in the remainder of 2020.

During the first quarter of 2020, the US economy contracted at its fastest pace, ending the longest US economic expansion on record. US gross domestic product, which is the broadest measure of goods and services produced across the economy, shrank by 4.8%¹, per preliminary third-party forecasts. This trend is expected to continue, resulting in an expected annualized growth rate of approximately -4.0% to -5.0%² for full-year 2020. The first quarter 2020 US employment cost index rose 2.8% and 0.8% on a year-over-year and sequential basis, respectively.

Despite declining rates over the past year amidst a challenging freight environment, which was further challenged by the effects of the COVID-19 pandemic, our Trucking segment showed resilience, generating an Adjusted Operating Ratio of 86.5% in the first quarter of 2020, which represents a 20 basis point improvement from the same quarter last year. Total miles per tractor increased by 0.2% in a volatile environment. Our Logistics segment produced an Adjusted Operating Ratio of 95.2% in the first quarter of 2020, primarily driven by a gross margin of 14.7% within our brokerage business. While rates and volumes across our reportable segments were pressured during the quarter, our focus on cost management contributed to operating efficiencies that helped mitigate some of the impacts from the uncertain economy, including a weaker used equipment market that negatively affected gain on sales of revenue equipment by $8.8 million (or $0.04 of earnings per diluted share, after taxes) on a year-over-year basis.

We anticipate that depreciation and amortization expense will increase and rental expense will correspondingly decrease, as a percentage of revenue excluding trucking fuel surcharge, as we intend to purchase, rather than lease, a majority of our revenue equipment in 2020. With significant tightening in the insurance markets, we may also experience changes in premiums and retention limits in 2020. We expect that our future fuel expenses will decrease as a result of the recently and rapidly deflating fuel prices. However, we believe any benefits experienced from lower fuel prices may be offset by reduced fuel surcharge revenues.

We continue to maintain our leverage ratio within our targeted range and remain committed to a strong capital structure, which we believe will position us for long-term success and enable us to pursue further opportunities for organic growth, growth through acquisitions, and other capital allocation opportunities. We do not foresee material liquidity constraints or any issues with our ongoing ability to meet our debt covenants.

Comparison Between the Quarters Ended March 31, 2020 and 2019 — The $22.5 million decrease in net income attributable to Knight-Swift to $65.4 million during the quarter ended March 31, 2020 from $87.9 million during the same period last year includes the following:

• Contributor — $7.8 million decrease in operating income within our Trucking Segment was primarily due to an $8.8 million reduction in gain on sales of revenue equipment, which was partially offset by a 3.2% decrease in operating expenses per total mile driven.

• Contributor — $5.1 million change from operating income to operating loss in our Intermodal Segment due to continued market pressures, including the impact of the COVID-19 pandemic.

• Contributor — $11.6 million unfavorable change in "Total other (expense) income, net," primarily attributed to unrealized losses in the first quarter of 2020 from our various equity investments, including our investments in TRP, as well as a $2.5 million unfavorable change associated with foreign currency fluctuations within our Mexico operations.

• Offset — $3.4 million decrease in consolidated income tax expense was primarily due to a decrease in earnings. During the first quarter of 2020, we recognized discrete items related to an increase in unfavorable foreign currency fluctuations, which was partially offset by an increase in stock compensation deductions. During the first quarter of 2019, we recognized discrete items related to a reduction in our reserve for uncertain tax positions and stock compensation deductions. All of these factors resulted in an effective tax rate of 27.2% for the first quarter of 2020 and 24.0% for the first quarter of 2019.

See additional discussion of our operating results within "Results of Operations — Consolidated Operating and Other Expenses" below.

Liquidity and Capital — During the quarter ended March 31, 2020, we generated $155.3 million in cash flows from operations, used $75.7 million for capital expenditures (net of equipment sales proceeds), reduced our operating lease liabilities by $11.4 million, repurchased $34.6 million worth of our common stock, and returned $14.0 million to our stockholders in the form of quarterly dividends. We ended the quarter with $119.1 million in unrestricted cash and cash equivalents, $294.0 million outstanding on the Revolver, $365.0 million face value outstanding on the Term Loan, and $5.7 billion of stockholders' equity. We remain committed to a strong capital structure, which we believe will position us for long-term success and enable us to pursue further opportunities for organic growth and growth through acquisition.

Segment Review

Trucking Segment

We generate revenue in the Trucking segment primarily through irregular route, dedicated, refrigerated, flatbed, expedited, and cross-border service offerings. Generally, we are paid a predetermined rate per mile or per load for our trucking services. Additional revenues are generated 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 segment 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 segment 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 statements of comprehensive income. 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 segment are depreciation and rent expenses from leasing and acquiring revenue equipment and terminals, as well as compensating our non-driver employees.

Comparison Between the Quarters Ended March 31, 2020 and 2019 — Operating Ratio was 88.3% in the first quarter of 2020 compared to 88.2% in the first quarter of 2019. We improved the Adjusted Operating Ratio within this segment to 86.5% in the first quarter of 2020 from 86.7% in the first quarter of 2019, despite an $8.8 million reduction in gain on sales of revenue equipment. Our cost control efforts contributed to a 3.2% decrease in operating expenses per total miles driven. Average revenue per tractor decreased by 2.7%, primarily as a result of a 3.1% decrease in revenue per loaded mile, excluding fuel surcharge and intersegment transactions.

Logistics Segment

The Logistics segment is less asset-intensive than the Trucking segment and is dependent upon capable non-driver employees, modern and effective information technology, and third-party capacity providers. Logistics revenue is primarily generated by its brokerage operations. 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). 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 Logistics segment is the (primarily) variable cost of purchased transportation that we pay to third-party capacity providers, included in "Purchased transportation" in the condensed consolidated statements of comprehensive income. Variability in this expense depends on truckload capacity, availability of third-party capacity providers, rates charged to customers, current freight demand, and customer shipping needs. Fixed Logistics operating expenses primarily include non-driver employee compensation and benefits recorded in "Salaries, wages, and benefits" and depreciation and amortization expense recorded in "Depreciation and amortization of property and equipment" in the condensed consolidated statements of comprehensive income.

Comparison Between the Quarters Ended March 31, 2020 and 2019 — Operating Ratio was 95.3% in the first quarter of 2020 compared to 91.8% in the first quarter of 2019. Adjusted Operating Ratio in the Logistics segment (which primarily consists of our brokerage services) increased to 95.2% in the first quarter of 2020 from 91.6% in the first quarter of 2019.

Brokerage-only — Brokerage gross margin decreased to 14.7% in the first quarter of 2020 from 17.8% in the first quarter of 2019. A 6.5% decrease in brokerage load volumes and a 3.8% decrease in brokerage revenue per load resulted in a 10.0% decrease in brokerage revenue, excluding intersegment transactions.

Intermodal Segment

The 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 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 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 statements of comprehensive income. Purchased transportation varies as it relates to rail capacity, freight demand, and customer shipping needs. The main fixed costs in the Intermodal segment are depreciation of our company tractors related to drayage, containers, and chassis, as well as non-driver employee compensation and benefits.

3 Includes 536 and 613 company-owned tractors for the quarters ended March 31, 2020 and 2019, respectively.

Comparison Between the Quarters Ended March 31, 2020 and 2019 — Operating Ratio was 102.9% in the first quarter of 2020 compared to 98.0% in the first quarter of 2019. During the first quarter of 2020, our Intermodal segment produced an Adjusted Operating Ratio of 102.8%, compared to 98.0% during the first quarter of 2019. Continued market pressures, including the impact of the COVID-19 pandemic, contributed to an 18.2% decrease in revenue, excluding intersegment transactions, as load counts decreased 13.2% and revenue per load decreased 5.8%.

Non-reportable Segments

The non-reportable segments include support services provided to our customers and independent contractors (including repair and maintenance shop services, equipment leasing, warranty services, and insurance), trailer parts manufacturing, warehousing, and certain driving academy activities, as well as certain corporate expenses (such as legal settlements and accruals, certain impairments, and $11.2 million in quarterly amortization of intangibles related to the 2017 Merger and various acquisitions).

Total revenue	$	46,242		$	37,764		22.4	%
Operating loss	$	(6,197	)	$	(8,520	)	(27.3	%)

Comparison Between the Quarters Ended March 31, 2020 and 2019 — The decrease in operating loss within the non-reportable segments was driven by additional operating income earned from warehousing activities in the first quarter of 2020, which was partially offset by losses from less revenue generated from support services provided to our independent contractors.

Results of Operations — Consolidated Operating and Other Expenses

Consolidated Operating Expenses

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

	Quarter Ended March 31,						Increase (Decrease)
	2020			2019
	(Dollars in thousands)
Salaries, wages, and benefits	$	354,833		$	363,855		(2.5	%)
% of total revenue	31.5		%	30.2		%	130	bps
% of revenue, excluding trucking fuel surcharge	34.5		%	33.2		%	130	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 a significant 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. We expect driving associate pay to remain inflationary, which could result in additional driving associate pay increases in the future.

• Comparison Between Quarters Ended March 31, 2020 and 2019 — The $9.0 million decrease within consolidated salaries, wages and benefits was primarily attributed to decreases in company driving associate wages based on the mix of company miles driven, favorable developments within workers' compensation expense, as well as lower medical insurance costs. These decreases were partially offset by incremental payroll premiums paid to our company driving associates and shop technicians in response to the COVID-19 pandemic. The COVID-19 expenses were clearly separable from our normal business operations and are not expected to recur once the pandemic subsides.

	2020			2019
	(Dollars in thousands)
Fuel	$	121,855		$	138,439		(12.0	%)
% of total revenue	10.8		%	11.5		%	(70	bps)
% of revenue, excluding trucking fuel surcharge	11.9		%	12.6		%	(70	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 segment. 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, management of tractor speeds, fleet updates for more fuel-efficient engines, management of fuel procurement, and driving associate training programs that we believe contribute to controlling our fuel expense.

• Comparison Between Quarters Ended March 31, 2020 and 2019 — The $16.6 million decrease in consolidated fuel expense is primarily due to a decrease in average DOE fuel prices to $2.92 per gallon for the quarter ended March 31, 2020 from $3.02 per gallon for the quarter ended March 31, 2019, which was partially offset by a 2.8% increase in the total miles driven by company driving associates.

Operations and maintenance	$	68,404		$	79,760		(14.2	%)
% of total revenue	6.1		%	6.6		%	(50	bps)
% of revenue, excluding trucking fuel surcharge	6.7		%	7.3		%	(60	bps)

Operations and maintenance expense consists of direct operating expenses, equipment maintenance, and tire expense.  Operations and maintenance expenses are affected by the age of our company-owned fleet of tractors and trailers. We expect the driver market to remain competitive throughout 2020, which could increase future driving associate development and recruiting costs and negatively affect our operations and maintenance expense. We expect to continue refreshing our tractor fleet in the coming quarters, and anticipate that maintenance costs will gradually decrease as we reduce the average age of our fleet.

The decrease of $11.4 million in consolidated operations and maintenance expense was attributed to reduced maintenance expense associated with refreshing our fleet with newer equipment, partially offset by the 2.8% increase in miles driven by company driving associates noted above.

Insurance and claims	$	54,280		$	50,136		8.3	%
% of total revenue	4.8		%	4.2		%	60	bps
% of revenue, excluding trucking fuel surcharge	5.3		%	4.6		%	70	bps

Insurance and claims expense consists of premiums for liability, physical damage, and cargo, and will vary based upon the frequency and severity of claims, as well as our level of self-insurance, and premium expense. In recent years, insurance carriers have raised premiums for many businesses, including transportation companies, and as a result, our insurance and claims expense could increase in the future, or we could raise our self-insured retention limits 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, our higher self-insured retention limits, as well as a tightening of excess insurance markets, may cause our consolidated insurance and claims expense to fluctuate more.

Consolidated insurance and claims expense increased by $4.1 million for the quarter ended March 31, 2020, as compared to the same period last year. This increase was primarily due to negative development within certain prior year losses partially offset by improvements within our current year experience as a result of lower frequency and severity in claims, as well as a decrease in total miles driven year over year.

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

Consolidated operating taxes and licenses increased by $0.4 million for the quarter ended March 31, 2020, as compared to the same period last year, but remained relatively flat as a percentage of revenue, excluding trucking fuel surcharge.

Depreciation and amortization of property and equipment	$	110,221		$	100,937		9.2	%
% of total revenue	9.8		%	8.4		%	140	bps
% of revenue, excluding trucking fuel surcharge	10.7		%	9.2		%	150	bps

Depreciation relates primarily to our owned tractors, trailers, buildings, electronic logging devices, 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. 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 Quarters Ended March 31, 2020 and 2019 — The $9.3 million increase in consolidated depreciation and amortization of property and equipment is primarily due to an increase in owned versus leased equipment.

We expect consolidated depreciation and amortization of property and equipment to increase both in total and as a percentage of consolidated revenue, excluding trucking fuel surcharge, as we currently do not plan to use operating leases as a primary means of funding our equipment purchases in the remainder of 2020.

The $0.8 million quarter over quarter increase in amortization of intangibles was attributed to an acquisition completed on January 1, 2020. See Note 4 in Part I, Item 1, of this Quarterly Report for more details regarding details of our acquisitions.

	Quarter Ended March 31,						Increase (Decrease)

	(Dollars in thousands)
Rental expense	$	25,375		$	35,545		(28.6	%)
% of total revenue	2.3		%	3.0		%	(70	bps)
% of revenue, excluding trucking fuel surcharge	2.5		%	3.2		%	(70	bps)

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

Consolidated rental expense decreased by $10.2 million for the quarter ended March 31, 2020, as compared to the same period last year. This was primarily due to increasing our ratio of owned versus leased equipment.

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

We expect consolidated rental expense to continue to decrease both in total and as a percentage of consolidated revenue, excluding trucking fuel surcharge, as we currently do not plan to use operating leases as a primary means of funding our equipment purchases in the remainder of 2020.

Purchased transportation	$	225,276		$	269,349		(16.4	%)
% of total revenue	20.0		%	22.4		%	(240	bps)
% of revenue, excluding trucking fuel surcharge	21.9		%	24.6		%	(270	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 grow our logistics and intermodal businesses. The increase could be partially offset if independent contractors exit the market due to regulatory changes.

Consolidated purchased transportation expense decreased by $44.1 million for the quarter ended March 31, 2020, as compared to the same period last year. This was primarily due to a decrease in miles driven by independent contractors of 22.5% and lower purchased transportation expense from third-party carrier activities in our Logistics and Intermodal segments.

Miscellaneous operating expenses primarily consist of legal and professional services fees, general and administrative expenses, other costs, as well as net gain on sales of equipment.

• Comparison Between Quarters Ended March 31, 2020 and 2019 — The $10.4 million increase in net consolidated miscellaneous operating expenses is primarily due to an $8.8 million decrease in gain on sales of equipment.

Other expense (income), net	6,507		(6,139		)	(206.0	%)
Income tax expense	24,554		27,923			(12.1	%)

Interest expense — Interest expense is comprised of debt and finance lease interest expense as well as amortization of deferred loan costs. The decrease in interest expense is primarily due to lower overall interest rates, partially offset by higher overall debt balances.

Other expense (income), net — Other expense (income), net is primarily comprised of unrealized (gains) and losses from our various equity investments, including our TRP investments accounted for under the equity method, as well as certain other non-operating income and expense items that may arise outside of the normal course of business. The $12.6 million unfavorable change is primarily attributed to unrealized losses in the first quarter of 2020 from our various equity investments, including our investments in TRP, as well as a $2.5 million unfavorable change associated with foreign currency fluctuations within our Mexico operations.

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.

• Comparison Between Quarters Ended March 31, 2020 and 2019 — The $3.4 million decrease in consolidated income tax expense was primarily due to a decrease in earnings. During the first quarter of 2020, we recognized discrete items related to an increase in unfavorable foreign currency fluctuations, which was partially offset by an increase in stock compensation deductions. During the first quarter of 2019, we recognized discrete items related to a reduction in our reserve for uncertain tax positions and stock compensation deductions. All of these factors resulted in an effective tax rate of 27.2% for the first quarter of 2020 and 24.0% for the first quarter of 2019.

Non-GAAP Financial Measures

The terms "Adjusted Net Income Attributable to Knight-Swift," "Adjusted EPS," "Adjusted Operating Income," 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, Adjusted Operating Income, 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, Adjusted Operating Income, 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, GAAP reportable segment operating income to non-GAAP reportable segment Adjusted Operating Income, and GAAP reportable segment operating ratio to non-GAAP reportable segment Adjusted Operating Ratio.

Liquidity and Capital Resources

Sources of Liquidity

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

Source	March 31, 2020
	(In thousands)
Cash and cash equivalents, excluding restricted cash	$	119,132
Availability under Revolver, due October 2022 ¹	474,906
Availability under 2018 RSA, due July 2021 ²	27,659
Total unrestricted liquidity	$	621,697
Cash and cash equivalents – restricted ³	40,972
Restricted investments, held-to-maturity, amortized cost ³	8,836
Total liquidity, including restricted cash and restricted investments	$	671,505

1 As of March 31, 2020, we had $294.0 million in borrowings under our $800.0 million Revolver. We additionally had $31.1 million in outstanding letters of credit (discussed below), leaving $474.9 million available under the Revolver.

2 Based on eligible receivables at March 31, 2020, our borrowing base for the 2018 RSA was $276.5 million, while outstanding borrowings were $180.0 million. We additionally had $68.8 million in outstanding letters of credit (discussed below), leaving $27.7 million available under the 2018 RSA. Refer to Note 9 in Part I, Item 1 of this Quarterly Report for more information regarding the 2018 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 $39.8 million, included in "Cash and cash equivalents — restricted" in the condensed consolidated balance sheet and held by Mohave and Red Rock for claims payments. The remaining $1.2 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 expect that net capital expenditures from the aforementioned projects will be in the range of $515.0 – $540.0 million for the full-year 2020. 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 finance 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 March 31, 2020, we had debt and finance lease obligations of $906.7 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 and lease obligations. Additionally, when our financial position allows, we periodically make voluntary prepayments on our outstanding debt balances.

Letters of Credit — Pursuant to the terms of the 2017 Debt Agreement and the 2018 RSA, our lenders may issue standby letters of credit on our behalf. When we have letters of credit outstanding, the availability under the Revolver or 2018 RSA is reduced accordingly. 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 March 31, 2020, the Company had $199.0 million remaining under the 2019 Knight-Swift Share Repurchase Plan. Additional details are discussed in Note 12 in Part I, Item 1 of this Quarterly Report.

Working Capital

As of March 31, 2020 and December 31, 2019, we had working capital deficits of $140.8 million and $103.0 million, respectively. The deficits were primarily due to the Term Loan maturing on October 2, 2020. We intend to refinance the Term Loan prior to its maturity.

Material Debt Agreements

As of March 31, 2020, we had $906.7 million in material debt obligations at the following carrying values:

• $364.9 million: Term Loan, due October 2020, net of $0.1 million in deferred loan costs

• $179.8 million: 2018 RSA outstanding borrowings, due July 2021, net of $0.2 million in deferred loan costs

• $68.0 million: Finance lease obligations

• $294.0 million: Revolver, due October 2022

As of December 31, 2019, we had $918.8 million in material debt obligations at the following carrying values:

• $364.8 million: Term Loan, due October 2020, net of $0.2 million in deferred loan costs

• $204.8 million: 2018 RSA outstanding borrowings, due July 2021, net of $0.2 million in deferred loan costs

• $70.2 million: Finance lease obligations

• $279.0 million: Revolver, due October 2022.

Net Cash Provided by Operating Activities

Comparison Between Quarters Ended March 31, 2020 and 2019 — The $88.1 million decrease in net cash provided by operating activities was primarily due to a $93.4 million cash settlement paid during the first quarter of 2020, associated with pre-2017 Merger legal matters that were previously accrued and disclosed by Swift.

Net Cash Used in Investing Activities

Comparison Between Quarters Ended March 31, 2020 and 2019 — The $80.9 million increase in net cash used in investing activities was due to a $46.8 million increase in net cash used for acquisitions and a $26.6 million increase in capital expenditures.

Net Cash Used in Financing Activities

Comparison Between Quarters Ended March 31, 2020 and 2019 — Net cash used in financing activities decreased by $145.9 million, which was primarily due to a $150.0 million increase in net borrowings on the Revolver.

Contractual Obligations

"Liquidity and Capital Resources," above, includes details regarding changes in our contractual obligations table during the quarter ended March 31, 2020 period. Aside from these items, there were no material changes to the contractual obligations table, which was included in our 2019 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 the 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 quarter ended March 31, 2020.

• Note 3 for accounting pronouncements issued during quarter ended March 31, 2020.

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 2018 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 2.0% as of March 31, 2020) and fixed rate equipment lease financing. Assuming the level of borrowings as of March 31, 2020, a hypothetical one percentage point increase in interest rates would increase our annual interest expense by $8.4 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 decreased to an average of $2.92 for quarter ended March 31, 2020 from an average of $3.02 for quarter ended March 31, 2019. We cannot predict the extent or speed of potential changes in fuel price levels in the future, the degree to which the lag effect of our fuel surcharge programs will impact us as a result of the timing and magnitude of such changes, or the extent to which effective fuel surcharges can be maintained and collected to offset such increases. We generally have not used derivative financial instruments to hedge our fuel price exposure in the past, but continue to evaluate this possibility.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

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

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2020, 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.

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 March 31, 2020, 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 2019 Annual Report, in the section entitled "Item 1A. Risk Factors," describes some of the risks and uncertainties associated with our business. In addition to the risk factors set forth in our Form 10-K, we believe the following additional risks and uncertainties should be considered in evaluating our business and growth outlook:

Our business and results of operations have been and will be, and our financial condition may be, impacted by the outbreak of COVID-19 or other similar outbreaks, and such impact could be materially adverse.

The global spread of the novel coronavirus (COVID-19) has created, and any other outbreaks of similar contagious diseases or other adverse public health developments could create, significant volatility, uncertainty and economic disruption. It is likely that the current outbreak or continued spread of COVID-19 will cause an economic slowdown, and it is possible that it could trigger a global recession. Risks related to a slowdown or recession are described in our risk factor titled “Our business is subject to general economic, credit, business, and regulatory factors affecting the truckload industry that are largely beyond our control, any of which could have a materially adverse effect on our results of operations” under "Item 1A. Risk Factors" in our 2019 Annual Report. The extent to which the COVID-19 outbreak or any other outbreak of disease or adverse public health development impacts our business, operations, liquidity, and financial results is highly uncertain and will depend on numerous evolving factors that we may not be able to accurately predict, including:

• the duration and geographic scope of the outbreak;

• current and potential governmental, business and individual actions taken in response to the outbreak, such as travel bans and restrictions, quarantines, shelter in place orders, social distancing measures, increased border and port controls and closures, and shutdowns, the length, scope, and severity of those actions, and the impact of those actions on global economic activity;

• the actions taken in response to economic disruption or demand uncertainty;

• expenses we may incur in connection with our response to the pandemic;

• the impact of business disruptions on the supply chain and our customers and the resulting impact on our customers' demand for our services;

• our customers' ability to pay for our services;

• the impact on the availability and cost of credit;

• our ability to provide our services, including as a result of our employees or our customers’ employees working remotely, closures of offices and facilities, and/or an increase in absences or terminations among our driving associates and non-driver personnel; and

• our ability to pay our quarterly dividend at prior levels.

FIRST AMENDMENT TO THE

KNIGHT-SWIFT TRANSPORTATION HOLDINGS INC.

AMENDED AND RESTATED

2012 EMPLOYEE STOCK PURCHASE PLAN

The Board of Directors of Knight-Swift Transportation Holdings Inc. (“Knight-Swift”) has determined that it is in the best interest of Knight-Swift and its stockholders to amend Knight-Swift’s Amended and Restated 2012 Employee Stock Purchase Plan (the “Plan”). Any capitalized terms that are not otherwise defined herein will have the meanings ascribed to such terms in the Plan. The Plan is hereby amended by adding a new Section 25, as follows:

25.Automatic Reinvestment of Cash Dividends. Effective as of the Offering Period beginning on January 1, 2020, all cash dividends paid on any shares of Common Stock that are credited to a Participant’s account as of a given dividend record date will not be distributed in the form of cash to the Participant but instead will be automatically reinvested in additional shares of Common Stock, as follows:

(a)Unless the Participant withdraws from participation in the automatic dividend reinvestment provisions of this Section 25 pursuant to Section 25(d), below, prior to a dividend record date, 100% of the cash dividends paid on shares of Common Stock credited to the Participant’s account as of the dividend record date will be used to purchase additional shares of Common Stock at a “Purchase Price” equal to 100% of the Fair Market Value of a share of Common Stock on the applicable dividend payment date. Upon the Participant’s withdrawal from the Plan as provided in Section 10(a)(ii) or Section 10(b), cash dividends paid on any shares of Common Stock that remain credited to the Participant’s account will continue to be automatically reinvested in additional shares of Common Stock until either (i) the Participant withdraws from participation in the automatic dividend reinvestment provisions of this Section 25 pursuant to Section 25(d), or (ii) the Participant otherwise sells or transfers the shares out of the account.

(b)Notwithstanding the provisions of Section 8(a), fractional shares will be purchased pursuant to this Section 25 and credited to the Participant’s account. Shares of Common Stock purchased pursuant to this Section 25 may be newly issued shares or treasury shares and will be subject to the limitation on shares available for sale under the Plan as set forth in Section 12.

(c)Any shares of Common Stock distributed as a result of a stock split, stock dividend or stock distribution with respect to the shares of Common Stock credited to a Participant’s account will be credited to such account. In the event of any other non-cash dividend or distribution in respect of the shares of Common Stock credited to a Participant’s account, the Company will, if reasonably practicable and at the direction of the Board, sell any property received in such dividend or distribution as promptly as practicable and use the proceeds to purchase additional shares of Common Stock in the same manner as set forth in Section 25(a) with respect to cash paid on the dividend payment date.

(d)A Participant may withdraw from participation in the automatic dividend reinvestment provisions of this Section 25 (without otherwise withdrawing from participation in the Plan) at any time by notifying the Company’s designated agent or third party administrator in such form, content, and process (including via telephonic or online process) as may be adopted from time to time by the designated agent or third party administrator for such purpose.

* * * * * * * * * * * * *

Except as amended as set forth above, the terms and conditions of the Plan and all other documents and agreements entered into between the Company and any Participants in the Plan shall remain in full force and effect.

Earnings Per Share [Abstract]

Weighted Average Shares Outstanding

Weighted Average Shares Outstanding

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

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

	Quarter Ended March 31,
	2020	2019
	(In thousands)
Basic weighted average common shares outstanding	170,617	172,971
Dilutive effect of equity awards	665	637
Diluted weighted average common shares outstanding	171,282	173,608
Anti-dilutive shares excluded from diluted earnings per share ¹	256	997

1

Shares were excluded from the dilutive-effect calculation because the outstanding awards' exercise prices were greater than the average market price of the Company's common stock for the periods presented.

Accounting Changes and Error Corrections [Abstract]

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

ASU 2016-13: Financial Instruments – Credit Losses (Topic 326) — Measurements of Credit Losses on Financial Instruments

Summary of the Standard — In June 2016, the FASB issued ASU 2016-13, which, in addition to several clarifying ASUs, established the new ASC Topic 326, Financial Instruments — Credit Losses ("CECL"). The new CECL standard amends the FASB's guidance on the impairment of financial instruments. Specifically, it adds the CECL impairment model to GAAP which is based on expected losses rather than incurred losses. This is intended to result in more timely recognition of such losses. Under the new CECL standard, an entity recognizes as an allowance its estimate of lifetime expected credit losses. The new CECL standard is also intended to reduce the complexity of GAAP by decreasing the number of credit impairment models that entities use to account for debt instruments. Further, the new CECL standard makes targeted changes to the impairment model for available-for-sale debt securities and moves the guidance from ASC Topic 320 to ASC Subtopic 326-30. For public business entities, the new standard was effective for annual and interim reporting periods beginning after December 15, 2019. For most debt instruments, entities are required to adopt the new CECL standard using a modified retrospective approach, meaning that entities will record a cumulative-effect adjustment to equity as of the beginning of the first reporting period in which the guidance is effective.

Practical Expedient — As permitted under ASU 2016-13 (and related ASUs), management elected to apply the collateral dependent financial asset practical expedient which allows entities to measure the expected credit losses for the financial asset by comparing the amortized cost basis with the fair value of the collateral at the reporting date, rather than using the fair value of the financial asset.

Current Period Impact of Adoption — The Company adopted ASC Topic 326 on January 1, 2020 using the modified retrospective approach. Upon adoption of the standard management assessed the potential impact of the CECL model on each type of the Company's financial assets and determined that there was no material impact on the Company's financial statements or accounting policies.

ASU 2018-15: Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

Summary of the Standard — In August 2018, the FASB issued ASU 2018-15, which amends ASC Subtopic 350-40 to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement that is a service contract ("Service CCA"). The amendments in ASU 2018-15 align the accounting for costs incurred to implement a Service CCA with previously codified guidance on capitalizing costs associated with developing or obtaining internal-use software.

Specifically, the ASU amends ASC Subtopic 350-40 to include in its scope implementation costs incurred with a Service CCA. This addition clarifies that a customer should apply the guidance from ASC Paragraph 350-40-25 to determine which stage the project is in before assessing whether implementation costs should be capitalized in a Service CCA that is considered a service contract. These capitalized items should be recorded within the same balance sheet line item as a prepayment for any fees.

Any capitalized costs from the Service CCA should be expensed over the term of the hosting arrangement, which includes the noncancelable period and any options to extend that are reasonably certain to be exercised and recorded in the same line item as fees associated with the hosting element of the arrangement. The amendments in this ASU were effective for public business entities for fiscal years beginning after December 15, 2019 and could be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption.

Current Period Impact of Adoption — The Company adopted the amendments in ASU 2018-15 on January 1, 2020 and elected to apply the amendments on a prospective basis to implementation costs incurred after the date of adoption. Upon review of the Service CCA's entered into during the first quarter of 2020, management has determined that adoption of the amendments has not had a material impact on the Company's financial statements and related accounting policies.

ASU 2017-04: Intangibles – Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment

Summary of the Standard — In January 2017, the FASB issued ASU 2017-04, which amends ASC Topic 350 by simplifying the goodwill impairment test. The amendments in this ASU are intended to simplify subsequent measurement of goodwill. The key amendment in the ASU eliminates Step 2 from the goodwill impairment test, in which entities measured a goodwill impairment loss by comparing the implied fair value to the carrying amount of a reporting unit's goodwill. Instead, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value with the carrying amount of a reporting unit and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The amendments also require companies to disclose the amounts of goodwill allocated to each reporting unit with a zero or negative carrying amount of assets. The amendments were effective for public business entities for fiscal years beginning after December 15, 2019 and should be applied on a prospective basis.

Current Period Impact of Adoption — The Company adopted the amendments in ASU 2017-14 on January 1, 2020 on a prospective basis. Management has updated the Company's accounting policy to incorporate the amendments in the ASU and has included the revised disclosure requirements below.

Refer to Note 7 for disclosures about the Company's goodwill balances.

Accounting Policy Update

Goodwill — Management evaluates goodwill on an annual basis as of June 30^th, or more frequently if indicators of impairment exist. The Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company conducts a quantitative goodwill impairment test. Management estimates the fair values of its reporting units using a combination of the income and market approaches. If the carrying amount of a reporting unit exceeds the fair value, then management will recognize an impairment loss of the same amount. This loss is only limited to the total amount of goodwill allocated to that reporting unit.

Other ASUs

There were various other ASUs that became effective during the quarter ended March 31, 2020, which did not have a material impact on the Company's results of operations, financial position, cash flows, or disclosures.

Recently Issued Accounting Pronouncements

Date Issued	Reference	Description	Adoption Date and Method	Financial Statement Impact
March 2020	2020-04: Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting 1	The amendments in this Update provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met.

The amendments in this ASU are effective for any interim period after March 12, 2020 and should be applied on a prospective basis.	March 2020	No material impact 2
March 2020	2020-03: Codification Improvements Financial Instruments 1	The amendments within this ASU updated several sections of the codification and how various topics and subtopics interacted due to new guidance on financial instruments. This includes addressing issues related to fair value option disclosures, line-of-credit or revolving-debt arrangements and leases among others. The amendments should be applied prospectively and have varying effective dates which were all in effect for public business entities prior to issuance of the ASU.	March 2020, Adoption Prospective	No material impact
February 2020	2020-02: Financial Instruments – Credit Losses (Topic 326), Leases – (Topic 842) – Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842) 1	The amendments in this ASU incorporate discussion from SEC Staff Accounting Bulletin No. 119 about expected implementation practices related to ASC Topic 326. The amendments also codify SEC Staff announcement that it would not object to the FASB's update to effective dates for major updates which were amended within ASU 2019-10.	January 2021, Adoption method varies by amendment	Adopted January 1, 2020, no material impact
January 2020	2020-01: Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions between Topic 321, Topic 323, and Topic 815	The amendments clarify that an entity should consider observable transactions when determining to apply or discontinue the equity method for the purposes of applying the measurement alternative. The amendments also clarify that an entity would not consider whether a purchased option would be accounted for under the equity method when applying ASC 815-10-15-141(a).	January 2021, Prospective	Currently under evaluation, but not expected to be material

1 Adopted during the first quarter of 2020.

2

As identified within the 2018 RSA, the lender can trigger an amendment by identifying and deciding upon a replacement for LIBOR. The Company's Term Loan also references LIBOR and management is currently underway with refinancing, as the Term Loan matures in October of 2020.

Transfers and Servicing [Abstract]

Accounts Receivable Securitization

Accounts Receivable Securitization

The 2018 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 receivable originator subsidiaries sell, on a revolving basis, undivided interests in all of their eligible accounts receivable to Swift Receivables Company II, LLC ("SRCII") who in turn sells a variable percentage ownership in those receivables to the various purchasers. The Company's eligible receivables are included in "Trade receivables, net of allowance for doubtful accounts" in the condensed consolidated balance sheets. As of March 31, 2020, the Company's eligible receivables generally have high credit quality, as determined by the obligor's corporate credit rating.

The 2018 RSA is subject to fees, various affirmative and negative covenants, representations and warranties, and default and termination provisions customary for facilities of this type. The Company was in compliance with these covenants as of March 31, 2020. Collections on the underlying receivables by the Company are held for the benefit of SRCII and the various purchasers and are unavailable to satisfy claims of the Company and its subsidiaries.

The following table summarizes the key terms of the 2018 RSA (dollars in thousands):

	2018 RSA
Effective date	July 11, 2018
Final maturity date	July 9, 2021
Borrowing capacity		$325,000
Accordion option ¹		$175,000
Unused commitment fee rate ²	20 to 40 basis points
Program fees on outstanding balances ³	one-month LIBOR + 80 to 100 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. As identified within the 2018 RSA, the lender can trigger an amendment by identifying and deciding upon a replacement for LIBOR.

Availability under the 2018 RSA is calculated as follows:

	March 31, 2020			December 31, 2019

Borrowing base, based on eligible receivables	$	276,500		$	299,100

Less: outstanding letters of credit	(68,841		)	(70,841		)
Availability under accounts receivable securitization facilities	$	27,659		$	23,259

1 Outstanding borrowings are included in "Accounts receivable securitization" in the condensed consolidated balance sheets, offset by $0.2 million of deferred loan costs as of March 31, 2020 and December 31, 2019. Interest accrued on the aggregate principal balance at a rate of 2.4% and 2.6% as of March 31, 2020 and December 31, 2019, respectively.

Program fees and unused commitment fees are recorded in "Interest expense" in the condensed consolidated statements of comprehensive income. The Company incurred accounts receivable securitization program fees of $1.4 million and $2.0 million during the quarters ended March 31, 2020 and 2019, respectively.

Knight-Swift is a transportation solutions provider, headquartered in Phoenix, Arizona. During the quarter ended March 31, 2020, the Company operated an average of 18,462 tractors (comprised of 16,339 company tractors and 2,123 independent contractor tractors) and 57,716 trailers within the Trucking segment. Additionally, the Company operated an average of 601 tractors and 9,856 containers in the Intermodal segment. The Company's three reportable segments are Trucking, Logistics, and Intermodal.

Basis of Presentation

The condensed consolidated financial statements and footnotes included in this Quarterly Report include the accounts of Knight-Swift Transportation Holdings Inc. and its subsidiaries and should be read in conjunction with the consolidated financial statements and footnotes included in Knight-Swift's 2019 Annual Report. 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.

Changes in Presentation

Changes in presentation associated with adopting accounting pronouncements are included in Note 2.

Beginning in the second quarter of 2019, the Company presents fuel surcharge revenue generated within only its Trucking segment within "Trucking fuel surcharge" in the condensed consolidated statements of comprehensive income. Fuel surcharge revenue generated within the remaining segments is included in "Revenue, excluding trucking fuel surcharge." Prior period amounts have been reclassified to align with the current period presentation.

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. These factors typically lead to lower operating profitability, as compared to 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 length of the holiday season (consumer shopping days between Thanksgiving and Christmas). However, cyclical changes in the trucking industry, including imbalances in supply and demand, can override the seasonality faced in the industry.

Impact of COVID-19

During the first quarter of 2020, COVID-19 became a global pandemic, which triggered a significant downturn in the global economy. The Company continues to operate its business through the COVID-19 pandemic and has taken many additional precautions to ensure the safety of its employees, customers, vendors, and the communities in which it operates. As part of the Company's efforts to safeguard its employees and promote business continuity, management has taken additional precautions to enhance the sanitization process of its equipment and properties, increase the social distancing of its employees by working remotely where possible, and provide driving associates with essential

provisions and enhanced bonus opportunities while they are over the road delivering freight to Knight-Swift's customers. During the first quarter of 2020, we incurred $2.3 million of incremental costs directly associated with COVID-19.

There are various uncertainties that have arisen from the COVID-19 pandemic. While management is continuing to monitor the impact of the pandemic on Knight-Swift, including its employees, customers, independent contractors, stockholders, and other business partners and stakeholders, it is difficult to predict the impact that the pandemic will have on future results of its operations, financial position, and liquidity. This has caused some uncertainties around various accounting estimates. Due to these uncertainties, our accounting estimates may change, as management's assessment of the impacts of the COVID-19 pandemic continues to evolve.

Accounting Policies [Abstract]

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill — Management evaluates goodwill on an annual basis as of June 30^th, or more frequently if indicators of impairment exist. The Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company conducts a quantitative goodwill impairment test. Management estimates the fair values of its reporting units using a combination of the income and market approaches. If the carrying amount of a reporting unit exceeds the fair value, then management will recognize an impairment loss of the same amount. This loss is only limited to the total amount of goodwill allocated to that reporting unit.

[1] Total unrealized losses for these investments are included within "Other (expense) income, net" within the condensed consolidated statements of comprehensive income for the quarter ended March 31, 2020. The Company did not sell any equity investments during the quarters ended March 31, 2020 or 2019 and therefore did not realize any losses on these investments.

[2] During the first quarter of 2020, the Company incurred impairment charges which were associated with revenue equipment held for sale and trailer tracking systems.

[3] During the second quarter of 2019, the Company incurred an impairment of leasehold improvements related to the early termination of a lease on one of its operating properties. This impairment was recorded in the Trucking segment.

[4] During the fourth quarter of 2019, the Company incurred impairment charges related to discontinued use of software systems. These impairments were allocated between the Logistics and non-reportable segments based on each segment's use of the assets.

[5] During the fourth quarter of 2019, the Company incurred impairment charges which were associated with certain revenue equipment technology, warehousing equipment no longer in use, and certain Swift legacy trailer models as a result of a softer used equipment market. These impairments were allocated between the Logistics and non-reportable segments based on each segment’s use of the assets.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Effective Tax Rate — The effective tax rate was 27.2% for the first quarter of 2020, compared to 24.0% for the first quarter of 2019. The Company recognized discrete items relating to foreign currency fluctuations and stock compensation deductions during the quarter ended March 31, 2020.

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 — Management believes it is reasonably possible that a decrease of up to $1.0 million in unrecognized tax benefits relating to federal deductions may be necessary within the next twelve months.

Interest and Penalties — Accrued interest and penalties related to unrecognized tax benefits was approximately $0.4 million for the periods ended March 31, 2020 and December 31, 2019.

Tax Examinations — The Company is currently under examination by the IRS for the 2012 tax year and management does not expect any adjustments that would have a material impact on the Company's effective tax rate. Certain of the Company's subsidiaries are also currently under examination by various state jurisdictions for tax years ranging from 2013 to 2018. 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 2014 remain subject to examination.

Acquisition

Acquisition

On January 1, 2020, pursuant to a stock purchase agreement (the "SPA") the Company acquired 100.0% of the equity interests of a warehousing-related company (the "Warehousing Co.") with locations throughout the Central US.

The total purchase price consideration of $66.9 million consisted of approximately $48.2 million in cash to the sellers at closing, and contingent consideration consisting of three additional annual payments of up to $8.1 million each (or $24.3 million in total), representing the maximum possible annual deferred payments to the sellers based on Warehousing Co.'s earnings before interest and taxes ("EBIT") for each of the calendar years ending December 31, 2020, December 31, 2021, and the annualized six-month period ending June 30, 2022. In order to estimate Warehousing Co.'s future performance, the Company utilized the Monte Carlo simulation method using certain inputs, including Warehousing Co.'s forecasted EBIT, discount rate, dividend yields, expected volatility, and expected stock returns during the above measurement periods. Based on the above inputs, the present value of the total contingent consideration was estimated to equal $18.7 million as of January 1, 2020. The Company funded the acquisition through cash-on-hand and borrowing on the Revolver on the date of the transaction. At closing, $6.8 million of the cash consideration was placed in escrow to secure certain of the sellers' indemnification obligations and remains subject to further adjustments.

The SPA 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 SPA contains customary representations, warranties, covenants, and indemnification provisions.

The goodwill recognized represents expected synergies from combining the operations of Warehousing Co. with the Company, including enhanced service offerings, 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 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.

The following table summarizes the fair value of the consideration transferred as of the acquisition date:

Fair Value Disclosures [Abstract]

Fair Value Measurement

Fair Value Measurement

ASC Topic 820, Fair Value Measurements and Disclosures, requires that the Company disclose estimated fair values for its financial instruments. The estimated fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market for the asset or liability. Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Changes in assumptions could significantly affect these estimates. Because the fair value is estimated as of March 31, 2020 and December 31, 2019, the amounts that will actually be realized or paid at settlement or maturity of the instruments in the future could be significantly different.

The estimated fair values of the Company's financial instruments 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.

Transportation Resource Partners — The estimated fair value of the Company's investments with Transportation Resource Partners are privately negotiated equity investments. The carrying amount of these investments approximates the fair value.

Equity Securities — The estimated fair value of the Company's investments in equity securities is based on quoted prices in active markets that are readily and regularly obtainable.

Debt Instruments and Leases — For notes payable under the Revolver and the Term Loan, fair value approximates the carrying value due to the variable interest rate. The carrying value of the 2018 RSA approximates fair value, as the underlying receivables are short-term in nature and only eligible receivables (such as those with high credit ratings) are qualified to secure the borrowed amounts. For finance and operating leases, the carrying value approximates the fair value, as the Company's finance and operating leases are structured to amortize in a manner similar to the depreciation of the underlying assets.

Other — Cash and cash equivalents, restricted cash, net accounts receivable, income tax refund receivable, and accounts payable represent financial instruments for which the carrying amount approximates fair value, as they are short-term in nature. These instruments are accordingly excluded from the disclosures below. All remaining balance sheet amounts excluded from the below are not considered financial instruments, subject to this disclosure.

The following table presents the carrying amounts and estimated fair values of the Company's major categories of financial assets and liabilities:

Segment Reporting [Abstract]

Information by Segment and Geography

Information by Segment and Geography

Segment Information

The Company has three reportable segments: Trucking, Logistics, and Intermodal, as well as the non-reportable segments, discussed below. Based on how economic factors affect the nature, amount, timing, and uncertainty of revenue or cash flows, the Company disaggregates revenues by reportable segment for the purposes of applying the ASC Topic 606 guidance.

Trucking

The Trucking segment is comprised of irregular route and dedicated, refrigerated, expedited, flatbed, and cross-border operations.

Logistics

The Logistics segment is primarily comprised of brokerage and other freight management services.

Intermodal

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

Non-reportable

The non-reportable segments include support services provided to the Company's customers and independent contractors (including repair and maintenance shop services, equipment leasing, warranty services, and insurance), trailer parts manufacturing, warehousing, and certain driving academy activities, as well as certain corporate expenses (such as legal settlements and accruals, certain impairments, and amortization of intangibles related to the 2017 Merger and various acquisitions).

Intersegment Eliminations

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

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

Accounting Changes and Error Corrections [Abstract]

Recently Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements

ASU 2016-13: Financial Instruments – Credit Losses (Topic 326) — Measurements of Credit Losses on Financial Instruments

Summary of the Standard — In June 2016, the FASB issued ASU 2016-13, which, in addition to several clarifying ASUs, established the new ASC Topic 326, Financial Instruments — Credit Losses ("CECL"). The new CECL standard amends the FASB's guidance on the impairment of financial instruments. Specifically, it adds the CECL impairment model to GAAP which is based on expected losses rather than incurred losses. This is intended to result in more timely recognition of such losses. Under the new CECL standard, an entity recognizes as an allowance its estimate of lifetime expected credit losses. The new CECL standard is also intended to reduce the complexity of GAAP by decreasing the number of credit impairment models that entities use to account for debt instruments. Further, the new CECL standard makes targeted changes to the impairment model for available-for-sale debt securities and moves the guidance from ASC Topic 320 to ASC Subtopic 326-30. For public business entities, the new standard was effective for annual and interim reporting periods beginning after December 15, 2019. For most debt instruments, entities are required to adopt the new CECL standard using a modified retrospective approach, meaning that entities will record a cumulative-effect adjustment to equity as of the beginning of the first reporting period in which the guidance is effective.

Practical Expedient — As permitted under ASU 2016-13 (and related ASUs), management elected to apply the collateral dependent financial asset practical expedient which allows entities to measure the expected credit losses for the financial asset by comparing the amortized cost basis with the fair value of the collateral at the reporting date, rather than using the fair value of the financial asset.

Current Period Impact of Adoption — The Company adopted ASC Topic 326 on January 1, 2020 using the modified retrospective approach. Upon adoption of the standard management assessed the potential impact of the CECL model on each type of the Company's financial assets and determined that there was no material impact on the Company's financial statements or accounting policies.

ASU 2018-15: Intangibles – Goodwill and Other – Internal Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

Summary of the Standard — In August 2018, the FASB issued ASU 2018-15, which amends ASC Subtopic 350-40 to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement that is a service contract ("Service CCA"). The amendments in ASU 2018-15 align the accounting for costs incurred to implement a Service CCA with previously codified guidance on capitalizing costs associated with developing or obtaining internal-use software.

Specifically, the ASU amends ASC Subtopic 350-40 to include in its scope implementation costs incurred with a Service CCA. This addition clarifies that a customer should apply the guidance from ASC Paragraph 350-40-25 to determine which stage the project is in before assessing whether implementation costs should be capitalized in a Service CCA that is considered a service contract. These capitalized items should be recorded within the same balance sheet line item as a prepayment for any fees.

Any capitalized costs from the Service CCA should be expensed over the term of the hosting arrangement, which includes the noncancelable period and any options to extend that are reasonably certain to be exercised and recorded in the same line item as fees associated with the hosting element of the arrangement. The amendments in this ASU were effective for public business entities for fiscal years beginning after December 15, 2019 and could be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption.

Current Period Impact of Adoption — The Company adopted the amendments in ASU 2018-15 on January 1, 2020 and elected to apply the amendments on a prospective basis to implementation costs incurred after the date of adoption. Upon review of the Service CCA's entered into during the first quarter of 2020, management has determined that adoption of the amendments has not had a material impact on the Company's financial statements and related accounting policies.

ASU 2017-04: Intangibles – Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment

Summary of the Standard — In January 2017, the FASB issued ASU 2017-04, which amends ASC Topic 350 by simplifying the goodwill impairment test. The amendments in this ASU are intended to simplify subsequent measurement of goodwill. The key amendment in the ASU eliminates Step 2 from the goodwill impairment test, in which entities measured a goodwill impairment loss by comparing the implied fair value to the carrying amount of a reporting unit's goodwill. Instead, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value with the carrying amount of a reporting unit and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The amendments also require companies to disclose the amounts of goodwill allocated to each reporting unit with a zero or negative carrying amount of assets. The amendments were effective for public business entities for fiscal years beginning after December 15, 2019 and should be applied on a prospective basis.

Current Period Impact of Adoption — The Company adopted the amendments in ASU 2017-14 on January 1, 2020 on a prospective basis. Management has updated the Company's accounting policy to incorporate the amendments in the ASU and has included the revised disclosure requirements below.

Refer to Note 7 for disclosures about the Company's goodwill balances.

Accounting Policy Update

Goodwill — Management evaluates goodwill on an annual basis as of June 30^th, or more frequently if indicators of impairment exist. The Company assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount. If the Company concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company conducts a quantitative goodwill impairment test. Management estimates the fair values of its reporting units using a combination of the income and market approaches. If the carrying amount of a reporting unit exceeds the fair value, then management will recognize an impairment loss of the same amount. This loss is only limited to the total amount of goodwill allocated to that reporting unit.

Other ASUs

There were various other ASUs that became effective during the quarter ended March 31, 2020, which did not have a material impact on the Company's results of operations, financial position, cash flows, or disclosures.

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 included in "Accrued liabilities" in the condensed consolidated balance sheets. The Company has recorded an aggregate accrual of approximately $27.7 million, relating to the Company's outstanding legal proceedings as of March 31, 2020.

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.
