Notes to Consolidated Financial Statements (Unaudited)

Note 1 — Introduction and Basis of Presentation

Certain acronyms and terms used throughout this Quarterly Report on Form 10-Q are specific to our company, commonly used in our industry, or are otherwise frequently used throughout our document. Definitions for these acronyms and terms are provided in the "Glossary of Terms," available in the front of this document.

Description of Business

Swift is a transportation solutions provider, headquartered in Phoenix, Arizona. As of March 31, 2017, the Company's fleet of revenue equipment included 18,656 tractors (comprised of 14,017 company tractors and 4,639 owner-operator tractors), 63,207 trailers, and 9,130 intermodal containers. The Company’s four reportable segments are Truckload, Dedicated, Refrigerated (formerly "Swift Refrigerated"), and Intermodal.

Subsequent Events

Merger

On April 10, 2017, Swift announced an all-stock merger agreement with Knight Transportation, Inc. ("Knight"), which was unanimously approved by the boards of directors of Swift and Knight and is expected to close during the quarter ended September 30, 2017. The combined company will be named Knight-Swift Transportation Holdings Inc. ("Knight-Swift"). Knight is expected to be the accounting acquirer. Under the terms of the definitive agreement each Swift share will convert into 0.72 shares of Knight-Swift by means of a reverse stock split. Each share of Knight will be exchanged for one Knight-Swift share. Based on the $30.65 closing price of Knight shares on April 7, 2017, the last trading day prior to the announcement, the implied value per share of Swift is $22.07. Upon closing of the transaction, Swift stockholders will own approximately 54.0% and Knight stockholders will own approximately 46.0% of the combined company. Based on Knight’s closing share price on April 7, 2017, the number of combined company shares expected to be outstanding after closing and the combined net debt of Swift and Knight as of December 31, 2016, the combined company would have an implied enterprise value of approximately $6.0 billion.

The merger agreement provides for certain termination rights for both Knight and the Company. Upon termination of the merger agreement under certain specified circumstances, the Company may be required to pay Knight a termination fee of $89.1 million and Knight may be required to pay the Company a termination fee of $75.3 million. In addition, if the merger agreement is terminated because of a failure of either Knight’s or the Company’s stockholders to approve the transactions contemplated by the merger agreement, the other party may be required to reimburse transaction expenses up to $10.0 million.

Legal Settlement

On April 13, 2017, the Company proposed a tentative settlement arrangement with regard to certain litigation in the Refrigerated segment, which was finalized on April 28, 2017, subject to final court approval. As such, the Company increased its legal accrual by $11.7 million for the quarter ended March 31, 2017.

Seasonality

In the truckload industry, results of operations generally show a seasonal pattern. As customers ramp up for the year-end holiday season, the late third quarter and fourth quarter have historically been the Company's strongest volume periods. As customers reduce shipments after the winter holiday season, the first quarter has historically been a lower-volume quarter than the other three quarters. In recent years, the macro consumer buying patterns combined with shippers’ supply chain management, which historically contributed to the fourth quarter "peak" season, continued to evolve. As a result, the Company's fourth quarter 2016, 2015, and 2014 volumes were more evenly distributed throughout the quarter, rather than peaking early in the quarter. In the eastern and mid-western United States, and to a lesser extent in the western United States, the Company's equipment utilization typically declines and operating expenses generally increase during the winter season. This tends to be attributed to declines in fuel efficiency from engine idling and increases in accident frequency, claims, and equipment repairs from severe weather. The Company's revenue is directly related to shippers' available working days. As such, curtailed operations and vacation shutdowns around the holidays may affect the Company's revenue. From time to time, the Company also suffers short-term impacts from severe weather and similar events, such as tornadoes, hurricanes, blizzards, ice storms, floods, fires, earthquakes, and explosions that could add volatility to, or harm, the Company's results of operations.

Basis of Presentation

The consolidated financial statements and footnotes included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and footnotes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016. The consolidated financial statements include the accounts of Swift Transportation Company and its wholly-owned subsidiaries. In management's opinion, these consolidated financial statements were prepared in accordance with GAAP and include all adjustments necessary for the fair presentation of the periods presented.

SWIFT TRANSPORTATION COMPANY

Changes in Presentation

Segment Reorganization— During the quarter ended March 31, 2017, the Company reorganized its reportable segments to reflect management’s revised reporting structure of its Dedicated and Refrigerated (formerly “Swift Refrigerated”) reportable segments.  In association with the reorganization, the operations of the Company's dedicated grocery line of business, which were previously reported within the Company’s Dedicated segment, are now reported within the Company's Refrigerated segment.  This resulted in all temperature-controlled lines of business reporting under the Refrigerated segment. Prior periods have been retrospectively adjusted to align with the current period presentation.

Recently Adopted Accounting Pronouncement — In March 2016, FASB issued ASU 2016-09, Improvements to Employee Share-based Payment Accounting, which amended ASC 718, Compensation – Stock Compensation. The amendments in this ASU are intended to simplify various aspects of accounting for stock-based compensation, including income tax consequences, classification of awards as equity or liability, as well as classification of activities within the statement of cash flows.  For public business entities, the amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2016, and the interim periods within those fiscal years. 

The Company adopted this guidance during the quarter ended March 31, 2017. The amendments that affected the Company's financial statements are discussed below.

• Accounting for Income Tax Benefits/Deficiencies: All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) should be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Modified retrospective application is required, by means of a cumulative-effect adjustment to equity.

Upon adoption, the Company reclassified approximately$16.8 million in historical net tax benefit/deficiency amounts previously recorded within "Additional paid-in capital" into "Accumulated deficit." Starting January 1, 2017, tax benefit/deficiency amounts are recorded in "Income tax expense" in the consolidated income statements.

• Classification of Excess Tax Benefits on the Statement of Cash Flows: Excess tax benefits should be classified along with other income tax cash flows as an operating activity. Application is permitted to be prospective or retrospective.

GAAP previously required classification within cash flows from financing activities. The Company retrospectively adjusted the statement of cash flows for the quarter ended March 31, 2016 to align with the current period presentation by increasing cash flows from operating activities by $0.1 million and correspondingly decreasing cash flows from financing activities by $0.1 million, reflecting the amount of excess tax benefits previously presented for that period.

• Forfeitures: An entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (prior GAAP) or account for forfeitures when they occur. Modified retrospective application is required, by means of a cumulative-effect adjustment to equity.

Upon adoption, the Company transitioned to accounting for forfeitures when they occur. This resulted in approximately a $0.4 million (net of income tax) cumulative-effect adjustment to retained earnings/accumulated deficit to catch-up the previously unrecognized stock-based compensation associated with historical assumed forfeiture rates. Starting January 1, 2017, forfeitures are recorded as adjustments to stock-based compensation as they occur.

• Classification of Employee Taxes Paid on the Statement of Cash Flows When an Employer Withholds Shares for Tax-withholding purposes: Cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. Retrospective application is required.

In 2016, the Company began allowing certain members of management to have shares withheld for taxes when their restricted stock awards and performance units vest. As such, upon adopting the amendments in this ASU, the Company reclassified the amounts out of cash flows from operating activities and into cash flows from financing activities for the quarter ended March 31, 2016 to align with the current period presentation. For the quarter-ended March 31, 2016, the amount was approximately$0.3 million.

____________

(1) Management is in the diagnostic phase of assessing the financial and business impacts of implementing ASC Topic 606, Revenue from Contracts with Customers, including identifying revenue sources within the Company's lines of business, reviewing a sample of contracts, and developing a preliminary assessment. Based upon these preliminary procedures, management anticipates that the following key considerations will impact the Company's accounting and reporting under the new standard:

• identification of what constitutes a contract in Swift's business practices,

• variability in individual contracts, such as customer-specific terms that may vary from the master agreement,

• principal versus agent determinations,

• timing of revenue recognition (for example, point-in-time versus over time and/or accelerated versus deferred),

• single versus multiple performance obligations,

• new/changed estimates and management judgments (for example, system estimation of in-transit accruals versus manual estimation),

• disaggregation of revenue by category within segments, and

• others.

Management expects that there will also be changes in sales, contracting, accounting, reporting, tax, debt covenants, and other business processes, policies, and controls, as a result of implementing ASC Topic 606. The Company is currently implementing a new ERP system and transacting a merger (as discussed in Note 1), which will also affect the implementation process.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) — CONTINUED

Based on the information currently available from the diagnostic phase, management cannot yet determine the quantitative impact on the financial statements; however, the impact is expected to be immaterial (potentially with changes only to the timing of revenue recognition between reportable periods, as well as changes in the requirements for accounting policy and other new disclosures). The financial impact has not yet been quantified. The Company is transitioning into the design and planning phase of implementing ASC Topic 606. Since management is continuing to evaluate the impact of ASC Topic 606, disclosures around their preliminary assessments are subject to change.

Note 5 — Income Taxes

Effective Tax Rate — The effective tax rate for the quarter endedMarch 31, 2017 was 31.3%, which was lower than management's expectation of 36.0%. The difference was primarily due to certain benefits relating to stock compensation deductions due to the Company's adoption of ASU 2016-09, partially offset by capitalized transaction costs relating to the merger with Knight recognized as discrete items in the quarter. Refer to Note 1 for further details regarding the Company's adoption of ASU 2016-09 and the merger with Knight.

The effective tax rate for the quarter endedMarch 31, 2016 was 29.8%, which was lower than management's expectation of 38.0%. The difference was primarily due to certain income tax credits received by the Company's foreign subsidiary and a reduction in the uncertain tax position reserve, recognized as discrete items in the quarter.

Interest and Penalties — Accrued interest and penalties related to unrecognized tax benefits as of March 31, 2017 and December 31, 2016 were approximately $0.4 million and $0.4 million, respectively. The Company does not anticipate a decrease of unrecognized tax benefits during the next twelve months.

Tax Examinations — Certain of the Company’s subsidiaries are currently under examination by the Internal Revenue Service and various state jurisdictions for tax years ranging from 2012 through 2015. At the completion of these examinations, management does not expect any adjustments that would have a material impact on the Company’s effective tax rate. Years subsequent to 2012 remain subject to examination.

Note 6 — Accounts Receivable Securitization

On December 10, 2015, SRCII, a wholly-owned subsidiary of the Company, entered into the 2015 RSA, which further amended the 2013 RSA. The parties to the 2015 RSA include SRCII as the seller, Swift Transportation Services, LLC as the servicer, the various conduit purchasers, the various related committed purchasers, the various purchaser agents, the various letters of credit participants, and PNC Bank, National Association as the issuing bank of letters of credit and as administrator. Pursuant to the 2015 RSA, the Company's receivable originator subsidiaries sell, on a revolving basis, undivided interests in all of their eligible accounts receivable to SRCII. In turn, SRCII sells a variable percentage ownership interest in the eligible accounts receivable to the various purchasers. The facility qualifies for treatment as a secured borrowing under ASC Topic 860, Transfers and Servicing. As such, outstanding amounts are classified as liabilities on the Company’s consolidated balance sheets. Refer to Note 14 for information regarding the fair value of the 2015 RSA.

As of March 31, 2017 and December 31, 2016, interest accrued on the aggregate principal balance at a rate of 1.5% and 1.3%, respectively. Program fees and unused commitment fees are recorded in "Interest expense" in the consolidated income statements. The Company incurred program fees of $1.4 million and $0.9 million related to the 2015 RSA during the quarter endedMarch 31, 2017 and 2016, respectively.

The 2015 RSA is subject to customary fees and contains various customary affirmative and negative covenants, representations and warranties, and default and termination provisions. Collections on the underlying receivables by the Company are held for the benefit of SRCII and the Purchasers in the facility and are unavailable to satisfy claims of the Company and its subsidiaries.

Credit Agreement

On July 27, 2015, the Company entered into the 2015 Agreement, which includes a Revolver and a Term Loan A. The following table presents the key terms of the 2015 Agreement:

Description	Term Loan A	Revolver (2)
	(Dollars in thousands)
Maximum borrowing capacity	$680,000	$600,000
Final maturity date	July 27, 2020	July 27, 2020

Minimum principal payment – frequency	Quarterly	Once
Minimum principal payment – commencement date (3)	December 31, 2015	July 27, 2020

____________

(1) The interest rate margin for the Term Loan A and Revolver is based on the Company's consolidated leverage ratio. As of March 31, 2017, interest accrued at 2.38% on the Term Loan A and 2.39% on the Revolver. As of December 31, 2016, interest accrued at 2.18% on the Term Loan A and 2.18% on the Revolver.

SWIFT TRANSPORTATION COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) — CONTINUED

(2) The commitment fee for the unused portion of the Revolver is based on the Company's consolidated leverage ratio and ranges from 0.25% to 0.35%. As of March 31, 2017, commitment fees on the unused portion of the Revolver accrued at 0.25% and outstanding letter of credit fees accrued at 1.50%. As of December 31, 2016, commitment fees on the unused portion of the Revolver accrued at 0.25% and outstanding letter of credit fees accrued at 1.50%.

(3) Commencing in March 2017, the minimum required quarterly payment amount on the Term Loan A is $12.3 million, at which it would remain until final maturity. However, as of January 2017, the Company has voluntarily prepaid all minimum quarterly principal payments through final maturity.

The Revolver and Term Loan A of the 2015 Agreement contain certain financial covenants with respect to a maximum leverage ratio and a minimum consolidated interest coverage ratio. The 2015 Agreement provides flexibility regarding the use of proceeds from asset sales, payment of dividends, stock repurchases, and equipment financing. In addition to the financial covenants, the 2015 Agreement includes customary events of default, including a change in control default and certain affirmative and negative covenants, including, but not limited to, restrictions, subject to certain exceptions, on incremental indebtedness, asset sales, certain restricted payments (including dividends and stock repurchases), certain incremental investments or advances, transactions with affiliates, engagement in additional business activities, and prepayment of certain other indebtedness. The anticipated merger with Knight discussed in Note 1 is not expected to be deemed a change in control, as defined in the 2015 Agreement.

Borrowings under the 2015 Agreement are secured by substantially all of the assets of the Company and are guaranteed by Swift Transportation Company, IEL, Central Refrigerated Transportation, LLC and its subsidiaries, and Swift Transportation Co., LLC and its domestic subsidiaries (other than its captive insurance subsidiaries, driver academy subsidiary, and its bankruptcy-remote special purpose subsidiary).

Note 9 — Leases

The Company finances a portion of its revenue equipment under capital and operating leases and certain terminals under operating leases.

Capital Leases (as Lessee) — The Company’s capital leases are typically structured with balloon payments at the end of the lease term equal to the residual value the Company is contracted to receive from certain equipment manufacturers upon sale or trade back to the manufacturers. If the Company does not receive proceeds of the contracted residual value from the manufacturer, the Company is still obligated to make the balloon payment at the end of the lease term. Certain leases contain renewal or fixed price purchase options. The present value of obligations under capital leases is included under "Current portion of capital lease obligations" and "Capital lease obligations, less current portion" in the consolidated balance sheets. As of March 31, 2017, the leases were collateralized by revenue equipment with a cost of $296.0 million and accumulated amortization of $91.3 million. As of December 31, 2016, the leases were collateralized by revenue equipment with a cost of $319.8 million and accumulated amortization of $97.0 million. Amortization of equipment under capital leases is included in "Depreciation and amortization of property and equipment" in the Company’s consolidated income statements.

Operating Leases (as Lessee) — Rent expense related to operating leases was $55.7 million and $56.3 million for the quarter endedMarch 31, 2017 and 2016, respectively.

Note 10 — Purchase Commitments

As of March 31, 2017, the Company's outstanding commitments to acquire revenue equipment were as follows:

• remainder of 2017: $277.0 million ($195.4 million of which were tractor commitments), and

• thereafter: none.

The Company typically has the option to cancel tractor purchase orders with 60 to 90 days' notice prior to the scheduled production, although there is a certain group of tractors we are committed to purchase in 2017 that cannot be canceled (even with advance notice). The notice period to cancel currently committed tractor purchase orders has lapsed for 78.0% of the total tractor commitments outstanding as of March 31, 2017. Purchases are expected to be financed by the combination of operating leases, capital leases, debt, proceeds from sales of existing equipment, and cash flows from operations.

As of March 31, 2017, the Company's outstanding purchase commitments to acquire facilities and non-revenue equipment were as follows:

• remainder of 2017: $10.7 million

• 2018 and 2019: $8.8 million, and

• thereafter: $3.9 million.

Factors such as potential future terminal expansions and changes in information technology infrastructure may change the amount of such expenditures.

Note 11 — Contingencies and Legal Proceedings

Accounting Policy

The Company is involved in certain claims and pending litigation primarily arising in the normal course of business. The majority of these claims relate to workers' compensation, auto collision and liability, physical damage, and cargo damage. The Company accrues for the uninsured portion of claims losses and the gross amount of other losses when the likelihood of the loss is probable and the amount of the loss is reasonably estimable. These accruals are based on management's best estimate within a possible range of loss. When there is no amount within the range of loss that appears to be a better estimate than any other amount, then management accrues to the low end of the range. Legal fees are expensed as incurred.

When it is reasonably possible that exposure exists in excess of the related accrual (which could be no accrual), management discloses an estimate of the possible loss or range of loss, unless an estimate cannot be determined.

If the likelihood of a loss is remote, the Company does not accrue for the loss. However if the likelihood of a loss is remote, but it is at least reasonably possible that one or more future confirming events may materially change management's estimate within twelve months from the date of the financial statements, management discloses an estimate of the possible loss or range of loss, unless an estimate cannot be determined.

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.

For the matters below, an estimate of the possible loss or range of loss cannot be determined for certain cases because, among other reasons, (1) the proceedings are in various stages that do not allow for assessment; (2) damages have not been sought; (3) damages are unsupported and/or exaggerated; (4) there is uncertainty as to the outcome of pending appeals; and/or (5) there are significant factual issues to be resolved.

Based on currently available information, and in certain cases, advice of outside counsel, management does not believe that loss contingencies arising from pending matters will have a material adverse effect on the Company's overall financial position, after taking into consideration any existing accruals. However, actual outcomes could be material to the Company's operating results or liquidity for any particular period.

Recent Developments and Current Status
For several years, the parties have been arguing over the proper venue in which to proceed. The plaintiffs argue that they signed contracts of employment, thus exempting them from arbitration under the Federal Arbitration Act, and claim that their case should be heard in court by a judge. The Company takes the position that these individuals signed independent contractor agreements and therefore can properly be required to submit their claims to arbitration. In January 2017, the district court issued an order finding that the plaintiffs had signed contracts of employment and thus the case could properly proceed in court. The Company has appealed this decision to the Ninth Circuit and the district court stayed the proceedings, pending resolution of the appeal. The Company intends to vigorously defend against any proceedings. The final disposition of the matter and impact to the Company cannot be determined at this time. The likelihood that a loss has been incurred is remote.

Utah Collective and Individual Arbitration
The plaintiffs allege that the Central Parties (defined below) misclassified owner-operator drivers as independent contractors and were therefore liable to these drivers for minimum wages and other employee benefits under the FLSA. The complaint also alleges a federal forced labor claim under U.S.C. §1589 and §1595, as well as fraud and other state-law claims.
Plaintiff(s)	Defendant(s)	Date instituted	Court or agency currently pending in
Gabriel Ciluffo, Kevin Shire, and Bryan Ratterree (1)	Central Refrigerated Service, Inc., Central Leasing, Inc., Jon Isaacson, and Jerry Moyes (the "Central Parties"), as well as Swift Transportation Company	June 1, 2012	American Arbitration Association
Recent Developments and Current Status
In June 2016, mediation commenced, but there was ultimately no settlement of the matter. In October 2016, the arbitrator ruled that approximately 1,300 Central Refrigerated Service, Inc. drivers were improperly classified as independent contractors, when they should have been classified and compensated as employees. The arbitrator ruled that damages could ultimately be assessed in a collective proceeding and denied the Company's motion to decertify the collective proceeding. Based upon the October 2016 arbitration ruling, the Company increased its legal accrual related to this matter for the quarter ended September 30, 2016. On April 14, 2017, the Company proposed a tentative settlement arrangement, which was finalized by and between the parties on April 28, 2017, subject to final court approval. As such, the Company increased its legal accrual again for the quarter ended March 31, 2017. The likelihood that a loss has been incurred is probable.

Other Contingencies

Demand for Inspection of Books and Records and Stockholder Derivative Lawsuit —During2016, the Company received several shareholder demands requesting to inspect the Company's books and records, pursuant to Section 220 of the Delaware General Corporation Law ("Section 220").  The demands relate to the shareholders' alleged investigation pertaining to whether the Board and Jerry Moyes have breached their fiduciary duties with respect to matters that have been publicly disclosed concerning the Company's securities trading policy, limitations on the pledging of Company stock on margin, share repurchases, the status of Board members as independent directors and other related matters. The Company has responded to the shareholders' requests received thus far. On February 9, 2017, a civil lawsuit was filed in the Court of Chancery of the State of Delaware (captioned as: Shiva Stein derivatively on behalf of Swift Transportation Company v. Jerry Moyes et al. and Swift Transportation Company as nominal defendant (the "Complaint")). The Complaint, initially filed as a confidential filing, is a purported derivative action alleging that the individual members of the Company's Board breached their fiduciary duties related to the Company's administration of its Securities Trading Policy and certain compensation actions related to Mr. Moyes.

In February 2017, the Company received a shareholder demand under Section 220 for books and records related to an alleged investigation into whether the Board breached its fiduciary duties in connection with the September 8, 2016 retirement agreement between the Company and Mr. Moyes. The Company is in the process of responding to this request.

Any future disposition or resolution of these matters cannot be determined at this time.

Environmental

The Company's tractors and trailers are involved in motor vehicle accidents, and experience damage, mechanical failures, and cargo issues as an incidental part of its normal course of operations.  From time to time, these matters result in the discharge of diesel fuel, motor oil, or other hazardous materials into the environment.  Depending on local regulations and who is determined to be at fault, the Company is sometimes responsible for the clean-up costs associated with these discharges.  As of March 31, 2017, the Company's estimate for its total legal liability for all such clean-up and remediation costs was approximately $0.3 million in the aggregate for all current and prior year claims.

Note 15 — Jerry Moyes' Retirement

In conjunction with the Company's September 8, 2016 announcement that Jerry Moyes would retire from his position as Chief Executive Officer effective December 31, 2016, the Company entered into an agreement with Mr. Moyes to memorialize the terms of his retirement. The Company contracted with Mr. Moyes to serve as a non-employee consultant from January 1, 2017 through December 31, 2019, during which time the Company will pay Mr. Moyes a monthly consulting fee of $0.2 million in cash. Additionally, the Company modified the vesting terms and forfeiture conditions of Mr. Moyes' previously-granted equity awards. As a result of the terms of the agreement, the Company incurred a one-time expense in September 2016 of $7.1 million, consisting of $6.8 million in accrued consulting fees and $0.3 million for the impact of the equity award modifications. The amounts were included in "Salaries, wages, and employee benefits" within the non-reportable segments' income statement.

The following schedule is a rollforward of the accrued liability for the consulting fees:

Note 16 — Information by Segment and Geography

Segment Information

The Company’s four reportable operating segments are Truckload, Dedicated, Refrigerated (formerly "Swift Refrigerated"), and Intermodal. See Note 1 regarding the reorganization of the Company's Dedicated and Refrigerated segments.

Truckload — The Truckload segment consists of one-way movements over irregular routes throughout the United States, Mexico, and Canada. This service utilizes both company and owner-operator tractors with dry van, flatbed, and other specialized trailing equipment.

Dedicated — Through the Dedicated segment, the Company devotes use of equipment to specific customers and offers tailored solutions under long-term contracts. This segment utilizes dry van, flatbed, and other specialized trailing equipment.

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

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

Non-reportable Segments — The non-reportable segments include the Company's logistics and freight brokerage services, as well as support services that its subsidiaries provide to customers and owner-operators, including repair and maintenance shop services, equipment leasing, and insurance. Intangible amortization related to the 2007 Transactions, certain legal settlements and reserves, and certain other corporate expenses are also included in the non-reportable segments.

Intersegment Eliminations — Certain operating segments provide transportation and related services for other affiliates outside their reportable segment. Revenues for such services are based on negotiated rates, which we believe approximate fair value, 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 our consolidated results.

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

Executive Summary

Company Overview — Swift is a multi-faceted transportation services company, operating one of the largest fleets of truckload equipment in North America from over 40 terminals near key freight centers and traffic lanes. We principally operate in short- to medium-haul traffic lanes around our terminals and dedicated customer locations. We concentrate on this length of haul because the majority of domestic truckload freight (as measured by revenue) moves in these lanes and our extensive terminal network affords us marketing, equipment control, supply chain, customer service, and driver retention advantages in local markets. Since our average length of haul is relatively short, it helps reduce competition from railroads and trucking companies that lack a regional presence.

Our four reportable segments are Truckload, Dedicated, Refrigerated, and Intermodal. Our extensive suite of service offerings (which includes line-haul services, dedicated customer contracts, temperature-controlled units, intermodal freight solutions, cross-border United States/Mexico and United States/Canada freight, flatbed hauling, freight brokerage and logistics, and others) provides our customers with the opportunity to "one-stop-shop" for their truckload transportation needs.

Revenue —We primarily generate revenue by transporting freight for our customers, generally at a predetermined rate per mile. We supplement this revenue by charging for fuel surcharges, stop-off pay, loading and unloading activities, tractor and trailer detention, and other ancillary services. The main factors that affect our revenue from transporting freight are the rate per mile we receive from our customers and loaded miles. The main factors that affect fuel surcharge revenue are the price of diesel fuel and the number of loaded miles. Fuel surcharges are billed on a lagging basis, meaning that we typically bill customers in the current week based on a previous week's applicable index. Therefore, in times of increasing fuel prices, we do not recover as much as we are currently paying for fuel. In periods of declining prices, the opposite is true.

Revenue in our non-reportable segments is generated by our non-asset-based freight brokerage and logistics management service, tractor leasing revenue from our financing subsidiaries, premium revenue from our captive insurance companies, and revenue from third parties serviced by our repair and maintenance shops. Main factors affecting revenue in our non-reportable segments are demand for brokerage and logistics services, as well as the number of equipment leases by our financing subsidiaries to the owner-operators we contract with and other third parties.

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

Compared to changes in rate per mile and loaded miles, changes in deadhead miles percentage generally have the largest proportionate effect on our profitability because we still bear all of the expenses for each deadhead mile, but do not earn any revenue to offset those expenses. Changes in rate per mile have the next largest proportionate effect on profitability because incremental improvements in rate per mile are not offset by any additional expenses. Changes in loaded miles generally have a smaller effect on profitability because variable expenses fluctuate with changes in miles. However, changes in mileage are affected by driver satisfaction and network efficiency, which indirectly affect expenses.

Recent Developments

Merger —On April 10, 2017, Swift and Knight Transportation, Inc. ("Knight") announced the Board approval of a merger of Knight and Swift in an all-stock transaction. The combined company will be named Knight-Swift Transportation Holdings Inc. ("Knight-Swift"). Further details regarding the merger are included in Note 1 in the Notes to Consolidated Financial Statements, included in Part I, Item 1: Financial Information, in this Quarterly Report on Form 10-Q, incorporated by reference herein.

Segment Recast — Refer Note 1 to the consolidated financial statements, included in Part I, Item 1 of this Quarterly Report on Form 10-Q for information regarding the reorganization of the Dedicated and Refrigerated (formerly "Swift Refrigerated") segments.

Company Strategy — The truckload freight environment in 2016 and into 2017 remained challenging. Excess industry capacity, excess customer inventories, and depressed shipping demand pressured volumes and pricing. We implemented the following initiatives to help counter the effects of these external factors:

• We downsized our core truckload fleet in an effort to improve asset utilization, and we continue to closely monitor and adjust our truckload fleet size to ensure proper utilization of our fleets.

• We selectively increased our participation in the spot market to improve network balance and help offset the lack of available freight in certain markets. Our sales team remains heavily focused on increasing freight levels with both new and existing customer contracts, with the goal of eventually reducing our spot market activity.

• We implemented several cost control initiatives throughout the organization, which include streamlining processes, reducing headcount, postponing non-critical system implementations, and reducing expenses in various other manners.

Results of Operations — Comparison Between the Quarter Ended March 31, 2017 and March 31, 2016

The $26.7 million decrease in net income from $31.9 million for the quarter endedMarch 31, 2016 to $5.2 million for the same period in 2017, reflects the following:

(1) $35.8 million decrease in Revenue xFSR — This was driven by decreases in the Truckload, Refrigerated, and non-reportable segments, partially offset by increases in Revenue xFSR in the Dedicated and Intermodal segments.

(2) $31.8 million increase in fuel surcharge revenue — Fuel prices were higher overall during the quarter endedMarch 31, 2017, which had an average DOE index of $2.57, compared to $2.08 for the same period in 2016.

(3) $20.0 million increase in fuel expense — This was primarily due to higher fuel prices.

(4) $1.8 million decrease in purchased transportation — This was attributed to lower logistics freight volumes which decreased payments to third-party carriers, as well as a 2.2% decrease in miles driven by owner-operators. This was partially offset by an increase in fuel reimbursements to owner-operators and other third parties as a result of higher fuel prices.

(5) $13.9 million increase in operating supplies and expenses — This was primarily due to an $11.7 million increase in legal accruals resulting from recent, unfavorable information regarding certain litigation within our Refrigerated segment.

(6) $11.1 million decrease in income tax expense — This was primarily driven by a decrease in income before income taxes. The effective tax rate for the quarter endedMarch 31, 2017 was31.3%, which was lower than our expectation of 36.0%. The difference was primarily due to certain benefits relating to stock compensation deductions due to our adoption of ASU 2016-09, partially offset by capitalized transaction costs relating to the merger with Knight, recognized as discrete items in the quarter.

The effective tax rate for the quarter endedMarch 31, 2016 was 29.8%, which was lower than our expectation of 38.0% The difference was primarily due to certain income tax credits received by our foreign subsidiary and a reduction in our uncertain tax position reserve, recognized as discrete items in the quarter.

Non-GAAP Financial Measures

The terms "Adjusted EPS," "Adjusted Operating Ratio," and "Adjusted EBITDA," 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 EPS, Adjusted Operating Ratio, and Adjusted EBITDA 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 and compliance with debt covenants.

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

Adjusted EPS —Our definition of the non-GAAP measure, Adjusted EPS, starts with (a) income (loss) before income taxes, the most comparable GAAP measure. We add the following items back to (a) to arrive at (b) adjusted income (loss) before income taxes:

(i) amortization of the intangibles from the 2007 Transactions,

(ii) non-cash impairments,

(iii) other special non-cash items,

(iv) excludable transaction costs,

(v) mark-to-market adjustments on our interest rate swaps, recognized in the income statement,

(vi) amortization of previous losses recorded in accumulated other comprehensive income (loss) related to the interest rate swaps we terminated upon our IPO and refinancing transactions in December 2010, and

(vii) severance expense, including cash and equity award impact, related to the departure of certain executive leadership.

We subtract income taxes, at the GAAP effective tax rate, from (b) to arrive at (c) adjusted earnings. Adjusted EPS is equal to (c) divided by weighted average diluted shares outstanding.

We believe that excluding the impact of derivatives provides for more transparency and comparability since these transactions have historically been volatile. Additionally, we believe that comparability of our performance is improved by excluding impairments that are unrelated to our core operations, as well as intangibles from the 2007 Transactions and other special items that are non-comparable in nature.

The following table is a GAAP to non-GAAP reconciliation for consolidated Adjusted EPS:

Note: Since the numbers reflected in the table below are calculated on a per share basis, they may not foot due to rounding.

____________

(1) "Amortization of certain intangibles" specifically reflects the non-cash amortization expense relating to certain intangible assets identified in the 2007 Transactions through which Swift Corporation acquired Swift Transportation Co, Inc.

(2) On April 10, 2017, Swift announced an all-stock merger agreement with Knight, which was unanimously approved by the boards of directors of Swift and Knight and is expected to close during the quarter ended September 30, 2017. The combined company will be named Knight-Swift Transportation Holdings Inc. ("Knight-Swift"). Swift incurred certain transactional expenses associated with the planned merger, which are added back for Adjusted EPS purposes.

Adjusted Operating Ratio — Our definition of the non-GAAP measure, Adjusted Operating Ratio, starts with (a) operating expense and (b) operating revenue, which are GAAP financial measures. We subtract the following items from (a) to arrive at (c) adjusted operating expense:

(i) fuel surcharge revenue,

(ii) amortization of the intangibles from the 2007 Transactions,

(iii) non-cash operating impairment charges,

(iv) other special non-cash items,

(v) excludable transaction costs, and

(vi) severance expense, including cash and equity award impact, related to the departure of certain executive leadership.

We then subtract fuel surcharge revenue from (b) to arrive at (d) Revenue xFSR. Adjusted Operating Ratio is equal to (c) adjusted operating expense as a percentage of (d) Revenue xFSR.

We net fuel surcharge revenue against fuel expense in the calculation of our Adjusted Operating Ratio, thereby excluding fuel surcharge revenue from operating revenue in the denominator. Because fuel surcharge revenue is so volatile, we believe excluding it provides for more transparency and comparability. Additionally, we believe that comparability of our performance is improved by excluding operating impairment charges, non-comparable intangibles from the 2007 Transactions, and other special items.

The following table is a GAAP to non-GAAP reconciliation for consolidated Adjusted Operating Ratio:

	Quarter Ended March 31,
	2017			2016

Adjusted EBITDA — Our definition of the non-GAAP measure, Adjusted EBITDA, starts with (a) net income (loss), the most comparable GAAP measure. We add the following items back to (a) to arrive at Adjusted EBITDA:

(i) depreciation and amortization,

(ii) interest and derivative interest expense, including fees and charges associated with indebtedness, net of interest income,

(iii) income taxes,

(iv) non-cash equity compensation expense,

(v) non-cash impairments,

(vi) other special non-cash items, and

(vii) excludable transaction costs.

We believe that Adjusted EBITDA is a relevant measure for estimating the cash generated by our operations that would be available to cover capital expenditures, taxes, interest, and other investments and that it enhances an investor’s understanding of our financial performance. We use Adjusted EBITDA for business planning purposes and in measuring our performance. Our method of computing Adjusted EBITDA is consistent with that used in our debt covenants, specifically in our leverage ratio, and is also routinely reviewed by management for that purpose.

The following table is a GAAP to non-GAAP reconciliation for consolidated Adjusted EBITDA:

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

Weekly Revenue xFSR per Tractor (monitored monthly) — This is our primary measure of productivity for our Truckload, Dedicated, and Refrigerated segments. Weekly Revenue xFSR per tractor is affected by the following factors, which are typically monitored daily:

• loaded miles (miles driven when hauling freight),

• fleet size (because available loads are spread over available tractors),

• rates received for our services, and

• network balance (number of loads accepted, compared to available trucks, by market).

We strive to increase our revenue per tractor by improving freight rates with customers, hauling more loads with existing equipment, effectively moving freight, managing balance within our network, maintaining our tractors, recruiting and retaining company drivers, and attracting and maintaining contracts with owner-operators.

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

Deadhead Miles Percentage (monitored daily) — This is calculated by dividing the number of unpaid miles by the total number of miles driven. We monitor deadhead miles percentage in Truckload and Refrigerated, as we strive to reduce our number of deadhead miles within these segments. By balancing our freight flows and planning consecutive loads with shorter distances between the drop-off and pick-up locations, we are able to reduce the percentage of deadhead miles driven to allow for more revenue-generating miles during our drivers’ hours-of-service. This also enables us to reduce wage, fuel, and other costs associated with deadhead miles.

Average Operational Truck Count (monitored daily) — We use this measure for all of our reportable segments. It includes tractors driven by company drivers as well as owner-operator units. This measure changes based on our ability to adjust our fleet size in response to changes in demand.

Load Count and Average Container Count (monitored daily) — Within Intermodal, we monitor load count and average container count. These metrics allow us to measure our utilization of our container fleet.

Adjusted Operating Ratio (monitored monthly) — We consider this ratio an important measure of our operating profitability for each of our reportable segments. We define and reconcile Adjusted Operating Ratio under "Non-GAAP Financial Measures" above. GAAP Operating Ratio is operating expenses as a percentage of revenue, or the inverse of operating margin, and produces an indication of operating efficiency. It is widely used in our industry as an assessment of management’s effectiveness in controlling all categories of operating expenses.

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

Truckload Revenue — The decrease in operating revenue for the quarter endedMarch 31, 2017, as compared to the same period in 2016, consisted of a $26.2 million decrease in Revenue xFSR, partially offset by a $15.2 million increase in fuel surcharge revenue, due to higher fuel prices. The 5.8% decrease in Revenue xFSR reflects the following:

• 2.6% decrease in Revenue xFSR per loaded mile, and a

• 3.2% decrease in total loaded miles.

The increase in weekly Revenue xFSR per tractor of 1.4% reflects the following:

• 2.6% decrease in Revenue xFSR per loaded mile, noted above, partially offset by the

• 4.0% increase in loaded miles per tractor per week.

Truckload volumes and pricing continued to be challenged during the quarter ended March 31, 2017 as carrier capacity continued to exceed current demand levels. To help combat the pricing environment, we remained focused on cost control and utilization, as evidenced by the increase in loaded miles per tractor per week, above. Efforts to improve freight selection and network balance resulted in a decrease in deadhead percentage, compared to the quarter ended March 31, 2016.

Truckload Operating Income —Operating income decreased for the quarter endedMarch 31, 2017, as compared to the same period in 2016, which was primarily driven by the factors discussed in "Truckload Revenue," above and "Truckload Adjusted Operating Ratio," below.

Truckload Adjusted Operating Ratio — Adjusted Operating Ratio increased 430 basis points for the quarter endedMarch 31, 2017, as compared to the same period in 2016, primarily driven by the decrease in Revenue xFSR, discussed above. In addition to the industry challenges associated with volumes and pricing that negatively affected Revenue xFSR, the continued soft used truck market contributed to an increase in depreciation expense (due to adjusting projected residual values of certain trucks in August of 2016) and a decrease in gain on disposals of property and equipment. Additionally, insurance and claims expense as a percentage of Revenue xFSR increased during the quarter ended March 31, 2017, compared to the quarter ended March 31, 2016.

Dedicated Revenue —The increase in operating revenue for the quarter endedMarch 31, 2017, as compared to the same period in 2016, consisted of a $4.8 million increase in fuel surcharge revenue, due to higher fuel prices and a $3.1 million increase in Revenue xFSR. The 2.3% increase in Revenue xFSR was primarily driven by a 3.7% increase in weekly Revenue xFSR per tractor from improved pricing and freight mix, and was partially offset by one less calendar day in the quarter ended March 31, 2017 compared to the same quarter in 2016.

Although the quarter ended March 31, 2017 was challenging, our sales pipeline has shown signs of strengthening, resulting in an increase in the number of pending bids for new business opportunities.

Dedicated Operating Income —Operating income decreased for the quarter endedMarch 31, 2017, as compared to the same period in 2016, which was primarily driven by the factors discussed within "Dedicated Adjusted Operating Ratio," below, which were partially offset by the factors discussed within "Dedicated Revenue," above.

Dedicated Adjusted Operating Ratio — Adjusted Operating Ratio increased 550 basis points for the quarter endedMarch 31, 2017, as compared to the same period in 2016. This was primarily driven by increases in insurance and claims, rent and depreciation, and equipment maintenance expenses as a percentage of Revenue xFSR, partially due to the severe weather during the quarter.

Refrigerated Revenue — The increase in operating revenue for the quarter endedMarch 31, 2017, as compared to the same period in 2016, consisted of an $8.9 million increase in fuel surcharge revenue, due to higher fuel prices, partially offset by a $1.1 million decrease in Revenue xFSR. The 0.7% decrease in Revenue xFSR reflects the following:

• 1.0% decrease in total loaded miles, partially offset by a

• 0.3% increase in Revenue xFSR per loaded mile.

The pricing environment of the refrigerated market began showing some signs of strengthening during the quarter ended March 31, 2017. Our sales organization continues to work closely with shippers to ensure freight is appropriately priced which may result in some customer and mix shifts. These efforts, along with working to improve asset utilization contributed to lower deadhead percentage, as well as an increase in weekly Revenue xFSR per tractor of 3.2%, which was favorably impacted by a 2.9% increase in loaded miles per tractor per week and the increase in Revenue xFSR per loaded mile, noted above.

Refrigerated Operating (Loss) Income — Refrigerated recognized an operating loss for the quarter endedMarch 31, 2017, as compared to operating income for the same period in 2016. The unfavorable change was driven by the factors discussed within "Refrigerated Adjusted Operating Ratio," below and partially offset by by the factors discussed within "Refrigerated Revenue," above.

Refrigerated Adjusted Operating Ratio —Adjusted Operating Ratio increased 680 basis points from the quarter endedMarch 31, 2016 to the quarter endedMarch 31, 2017, which was primarily driven by an $11.7 million increase in legal accruals resulting from recent, unfavorable information regarding certain litigation within this segment.

Intermodal Revenue — The increase in operating revenue for the quarter endedMarch 31, 2017, as compared to the same period in 2016, consisted of a $3.5 million increase in fuel surcharge revenue, due to higher fuel prices, and a $0.2 million increase in Revenue xFSR. The 0.3% increase in Revenue xFSR includes the following:

• 1.1% increase in Revenue xFSR per load, partially offset by a

• 0.8% decrease in load count.

During the quarter ended March 31, 2017, we experienced strengthening in container-on-flat-car load counts. Additionally, we were awarded several new bids during the quarter ended March 31, 2017, and we believe this growth will contribute to operational efficiencies going forward.

Intermodal Operating Loss —Operating loss decreased for the quarter endedMarch 31, 2017, as compared to the same period in 2016. This was primarily driven by the factors discussed within "Intermodal Revenue," above and "Intermodal Adjusted Operating Ratio," below.

Intermodal Adjusted Operating Ratio — Adjusted Operating Ratio decreased 370 basis points for the quarter endedMarch 31, 2017, as compared to the same period in 2016. This was primarily driven by the favorable impacts from our initiatives to improve our cost infrastructure and operational efficiencies (such as dray efficiency and network optimization) and the slight increase in Revenue xFSR, discussed above.

Results of Operations — Consolidated Operating and Other Expenses

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

Consolidated Expenses — Comparison Between the Quarter EndedMarch 31, 2017 and March 31, 2016

	Quarter Ended March 31,						Increase (Decrease)
	2017			2016			Amount			Percentage
	(Dollars in thousands)
Salaries, wages, and employee benefits	$	283,338		$	288,633		$	(5,295	)	(1.8	)%
% of operating revenue	29.4		%	29.8		%				(0.4	)%
% of Revenue xFSR	32.5		%	31.8		%				0.7	%

Salaries, wages, and employee benefits are primarily affected by the total number of miles driven by company drivers, the rate per mile we pay our company drivers, and employee benefits, including health care, workers' compensation, and other benefits. Typically to a lesser extent, non-driver employee headcount, compensation, and benefits affect the expense.

The decrease in salaries, wages, and employee benefits was primarily due to a 2.3% decrease in total miles driven by company drivers and a decrease in employee benefits expense during the quarter ended March 31, 2017, compared to the quarter ended March 31, 2016.

	Quarter Ended March 31,						Increase (Decrease)
	2017			2016			Amount		Percentage
	(Dollars in thousands)
Operating supplies and expenses	$	104,119		$	90,215		$	13,904	15.4	%
% of operating revenue	10.8		%	9.3		%			1.5	%
% of Revenue xFSR	12.0		%	9.9		%			2.1	%

Operating supplies and expenses primarily consist of vehicle repairs and maintenance, costs associated with preparing tractors and trailers for sale or trade-in, driver expenses, driver recruiting costs, legal and professional services fees, general and administrative expenses, and other costs. Operating supplies and expenses are primarily affected by the age of our company-owned fleet of tractors and trailers, the number of miles driven in a period, driver turnover, and typically to a lesser extent by efficiency measures in our repair and maintenance shops.

The increase in operating supplies and expenses was primarily due to an $11.7 million increase in legal accruals resulting from recent, unfavorable information regarding certain litigation within our Refrigerated segment.

	Quarter Ended March 31,						Increase (Decrease)
	2017			2016			Amount		Percentage
	(Dollars in thousands)
Fuel expense	$	94,961		$	74,987		$	19,974	26.6	%
% of operating revenue	9.9		%	7.7		%			2.2	%
% of Revenue xFSR	10.9		%	8.3		%			2.6	%

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 number of miles driven by company drivers.

We believe the most effective protections against fuel cost increases are maintaining a fuel-efficient fleet by incorporating fuel efficiency measures into our business, such as aerodynamic equipment, slower tractor speeds, engine idle limitations, and a reduction of deadhead miles; actively managing fuel procurement; and maintaining an effective fuel surcharge program. To mitigate unrecovered fuel exposure, we have worked to negotiate more robust surcharge programs with customers identified as having inadequate programs. We generally have not used derivatives to hedge against higher fuel costs in the past, but continue to evaluate this possibility.

Fuel prices were higher overall during the three months ended March 31, 2017, which had an average DOE index of $2.57, compared to the same period in 2016, which had an average DOE index of $2.08. The increase in fuel expense was the result of these higher fuel prices, partially offset by the decrease in total miles driven by company drivers, noted above. Fuel efficiency during the quarter ended March 31, 2017 slightly improved from the same quarter in 2016.

	Quarter Ended March 31,						Increase (Decrease)
	2017			2016			Amount			Percentage
	(Dollars in thousands)
Purchased transportation expense	$	265,511		$	267,309		$	(1,798	)	(0.7	)%
% of operating revenue	27.5		%	27.6		%				(0.1	)%
% of Revenue xFSR	30.5		%	29.5		%				1.0	%

Purchased transportation expense includes payments made to owner-operators, rail partners, and other third parties that we use for intermodal drayage and other brokered business. The decrease in the expense was attributed to lower logistics freight volumes which decreased payments to third-party carriers, as well as a 2.2% decrease in miles driven by owner-operators. This was partially offset by an increase in fuel reimbursements to owner-operators and other third parties as a result of higher fuel prices.

	Quarter Ended March 31,						Increase (Decrease)
	2017			2016			Amount		Percentage
	(Dollars in thousands)
Insurance and claims	$	50,176		$	47,710		$	2,466	5.2	%
% of operating revenue	5.2		%	4.9		%			0.3	%
% of Revenue xFSR	5.8		%	5.3		%			0.5	%

Insurance and claims expense consists of insurance premiums and estimated payments and expenses for claims for bodily injury, property damage, cargo damage, and other casualty events, as well as owner-operator policies through our captive insurance subsidiary. The primary factors affecting our insurance and claims are the number of miles driven by our drivers and owner-operators, the frequency and severity of accidents, trends in the development factors used in our actuarial accruals, and developments in large, prior-year claims. Furthermore, our self-insured retention of $10.0 million per occurrence for accident claims can cause volatility in this expense.

Insurance and claims expense increased, primarily due to severe weather conditions during the quarter ended March 31, 2017, compared to the quarter ended March 31, 2016.

	Quarter Ended March 31,						Increase (Decrease)
	2017			2016			Amount		Percentage
	(Dollars in thousands)
Rental expense and depreciation and amortization of property and equipment	$	123,463		$	123,203		$	260	0.2	%
% of operating revenue	12.8		%	12.7		%			0.1	%
% of Revenue xFSR	14.2		%	13.6		%			0.6	%

Rental expense consists primarily of payments for tractors and trailers financed with operating leases. Depreciation and amortization of property and equipment consists primarily of depreciation for owned tractors and trailers and amortization of those financed with capital leases. The primary factors affecting these expense items are the size and age of our revenue equipment fleet, the cost of new equipment, and the relative percentage of owned versus leased equipment. We believe it is appropriate to combine our rental expense with our depreciation and amortization of property and equipment for analytical purposes because the mix of our leased versus owned tractors varies from period to period.

Combined rental expense and depreciation and amortization of property and equipment was relatively consistent from the quarter ended March 31, 2016 to the quarter ended March 31, 2017, but increased as a percentage of Revenue xFSR over the same comparable periods. The continued soft used truck market contributed to an increase in depreciation expense (due to adjusting projected residual values of certain trucks in August of 2016), but this was partially offset by a decrease in tractor and trailer counts from March 31, 2016 to March 31, 2017.

Gain on disposal of property and equipment	$	4,195		$	6,326		$	(2,131	)	(33.7	)%
% of operating revenue	0.4		%	0.7		%				(0.3	)%
% of Revenue xFSR	0.5		%	0.7		%				(0.2	)%

Gain on disposal of property and equipment is dependent upon the number of tractors and trailers that we have available for trade or sale during the period, execution of those sales, the type of equipment we are selling, and the used equipment market, among other things.

The decrease in gain on disposal of property and equipment was primarily driven by a decrease in volume of trailers sold, as well as lower gain on disposals of tractors, due to a soft used truck market in the quarter ended March 31, 2017, compared to the same period in 2016.

Other Expenses —The following table summarizes fluctuations in certain non-operating expenses included in our consolidated income statements for the quarter endedMarch 31, 2017, as compared to the quarter endedMarch 31, 2016.

	Quarter Ended March 31,				Increase (Decrease)
	2017		2016		Amount			Percentage

Income tax expense	$	2,371	$	13,511	$	(11,140	)	(82.5	)%

Interest Expense—Interest expense is comprised of debt interest expense and amortization of DLCs. The decrease in interest expense was primarily driven by overall lower debt balances during the quarter ended March 31, 2017, compared to the same period in 2016.

Merger Transaction Costs—On April 10, 2017, Swift announced an all-stock merger agreement with Knight Transportation, Inc. ("Knight"), which was unanimously approved by the boards of directors of Swift and Knight and is expected to close during the quarter ended September 30, 2017. The combined company will be named Knight-Swift Transportation Holdings Inc. ("Knight-Swift"). Swift incurred certain transactional expenses associated with the planned merger, which are included in "Merger transaction costs" in the consolidated income statement.

Income Tax Expense— The effective tax rate for the quarter endedMarch 31, 2017 was31.3%, which was lower than our expectation of 36.0%. The difference was primarily due to certain benefits relating to stock compensation deductions due to our adoption of ASU 2016-09, partially offset by capitalized transaction costs relating to the merger with Knight, recognized as discrete items in the quarter. We expect the remaining 2017 quarterly GAAP effective tax rate to be 36.0%, before discrete items. The Notes to Consolidated Financial Statements in Part I, Item 1: Financial Information include additional details regarding our adoption of ASU 2016-09 and the merger with Knight in Note 1 and additional details related to income taxes in Note 5.

The effective tax rate for the quarter endedMarch 31, 2016 was 29.8%, which was lower than our expectation of 38.0%. The difference was primarily due to certain income tax credits received by our foreign subsidiary and a reduction in our uncertain tax position reserve, recognized as discrete items in the quarter.

Liquidity and Capital Resources

Sources of Liquidity

The following table presents our available sources of liquidity:

Source	March 31, 2017
	(In thousands)
Cash and cash equivalents, excluding restricted cash	$	61,770
Availability under Revolver, due July 2020 (1)	494,800
Availability under 2015 RSA, due January 2019 (2)	8,700
Total unrestricted liquidity	$	565,270
Cash and cash equivalents – restricted (3)	54,945
Restricted investments, held to maturity, amortized cost (3)	22,859
Total liquidity, including restricted cash and restricted investments	$	643,074

____________

(1) As of March 31, 2017, we had $10.0 million in borrowings under the $600.0 million Revolver. We additionally had $95.2 million in outstanding letters of credit (discussed below), leaving $494.8 million available under the Revolver.

(2) Based on eligible receivables at March 31, 2017, our borrowing base for the 2015 RSA was $313.7 million, while outstanding borrowings were $305.0 million, gross of DLCs.

(3) Restricted cash and cash equivalents, and restricted short-term investments are primarily held by our captive insurance companies for claims payments.

Uses of Liquidity

Our business requires substantial amounts of cash for operating activities, including salaries and wages paid to our employees, contract payments to owner-operators, 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, and fund growth in our revenue equipment fleet. We expect net cash capital expenditures throughout the remainder of 2017 to increase compared to the amount spent during the quarter ended March 31, 2017. In addition to this, we expect to continue to obtain a portion of our equipment under operating and capital leases. 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 revolving credit facility (if not then fully drawn), extend the maturity of then-outstanding debt, rely on alternative financing arrangements, or engage in asset sales.

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 leases, which are not subject to debt incurrence baskets, the capital lease basket, available funds under the 2015 RSA, and availability under the Revolver will be sufficient to fund our expected capital expenditures for at least the next twelve months.

• Principal and Interest Payments— As of March 31, 2017, we had material debt and capital lease obligations of $1.0 billion, which are discussed under "Material Debt Agreements," below. A significant amount of our cash flows from operations are committed to minimum payments of principal and interest on our 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 2015 Agreement, our lenders may issue standby letters of credit on our behalf. When we have letters of credit outstanding, it reduces the availability under the $600.0 million Revolver. Standby letters of credit are typically issued for the benefit of third-party 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. Our outstanding letters of credit have historically been in the range of $95.0 million to $150.0 million.

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

• Share Repurchases— From time to time, and depending on free cash flow availability, debt levels, stock prices, general economic and market conditions, as well as Board approval, we may repurchase shares of our outstanding common stock. In September 2015, the Board authorized the Company to repurchase up to $100.0 million of its outstanding Class A common stock. We finished our repurchases under this authorization in January 2016. In February 2016, the Board authorized an additional $150.0 million in Class A common stock share repurchases, of which $62.9 million remained available as of March 31, 2017. Given the pending merger with Knight, we do not anticipate any share repurchases prior to the expected close. See further details regarding our share repurchases under Note 12 in the Notes to Consolidated Financial Statements, included in Part I, Item 1: Financial Information.

Working Capital

As of March 31, 2017 and December 31, 2016, we had a working capital surplus of $185.9 million and $246.0 million, respectively.

Material Debt Agreements

As of March 31, 2017, we had $1.0 billion in material debt obligations at the following carrying values:

• $470.5 million: Term Loan A, due July 2020, net of $1.2 million DLC

• $211.5 million: Capital lease obligations

• $10.0 million: Revolver, due July 2020

• $6.4 million: Other

As of December 31, 2016, we had $1.1 billion in material debt obligations at the following carrying values:

• $492.9 million: Term Loan A, due July 2020, net of $1.3 million DLC

• $279.3 million: 2015 RSA outstanding borrowings, due January 2019, net of $0.7 million DLC

• $233.9 million: Capital lease obligations

• $130.0 million: Revolver, due July 2020

• $8.9 million: Other

The $13.2 million decrease in net cash provided by operating activities for the quarter endedMarch 31, 2017, as compared to the quarter endedMarch 31, 2016, consisted of:

Unfavorable Cash Flow Variances:

(1) $36.9 million decrease in operating income, driven by the factors discussed in "Results of Operations — Segment Review" and "Results of Operations — Consolidated Operating and Other Expenses," above.

(2) $9.8 million decrease in net cash related to prepaid expenses and other current assets, primarily related to changes in the income tax refund receivable balance and amortization of prepaids.

(3) $3.1 million decrease in net cash related to other (long-term) assets, primarily associated with down payments.

(4) $1.0 million net remaining unfavorable variance was related to various factors that had an immaterial impact on net cash provided by operating activities.

Favorable Cash Flow Variance:

(5) $37.6 million increase in operating cash flows related to changes in accounts payable, accrued, and other liabilities, primarily due to timing differences in payments to our vendors, as well as changes in accrued liabilities balances.

The $2.6 million increase in net cash used in investing activities for the quarter endedMarch 31, 2017, as compared to the quarter endedMarch 31, 2016, consisted of:

Unfavorable Cash Flow Variance:

(1) $7.1 million decrease in proceeds from sale of property and equipment. This was primarily driven by a decrease in proceeds from tractor sales partially due to the soft used truck market. Additionally, at the end of 2015, we had a significant backlog of tractors that were being processed for trade or sale. During the quarter ended March 31, 2016, we worked through the entire backlog, which contributed to higher proceeds from sale of property and equipment during that quarter. We also sold fewer trailers during the quarter ended March 31, 2017, compared to the quarter ended March 31, 2016.

Favorable Cash Flow Variances:

(2) $4.2 million favorable change in restricted cash and cash equivalents. Changes in the balance are driven by the amount and timing of future claims payments by our captive insurance companies. The restricted cash and cash equivalents balance decreased $2.1 million during the quarter endedMarch 31, 2017, as compared to the quarter endedMarch 31, 2016, when it increased $2.1 million.

(3) $0.3 million net remaining favorable variance was related to various factors that had an immaterial impact on net cash used in investing activities.

Unfavorable Cash Flow Variance:

(1) $120.0 million increase in net repayments on the revolving line of credit.  We repaid $120.0 million on the Revolver during the quarter endedMarch 31, 2017 and did not repay any amounts on the revolving line of credit during the quarter endedMarch 31, 2016.

Favorable Cash Flow Variances:

(2) $45.0 million decrease in cash used to repurchase shares our outstanding Class A common stock. We did not repurchase any shares of our our Class A common stock during the quarter ended March 31, 2017, as compared to the quarter ended March 31, 2016, when we repurchased $45.0 million shares of our Class A common stock. See further details regarding our share repurchases under Note 12 in the Notes to Consolidated Financial Statements, included in Part I, Item 1: Financial Information.

(3) $25.0 million favorable cash flow variance related to accounts receivable securitization. During the quarter endedMarch 31, 2017, we received proceeds from advances of $25.0 million under the 2015 RSA, as compared to the quarter endedMarch 31, 2016, when we did not borrow under the 2015 RSA.

(4) $3.1 million net remaining favorable variance was related to various factors that had an immaterial impact on net cash used in financing activities.

Seasonality

Discussion regarding the impact of seasonality on our business is included in Note 1 in the Notes to Consolidated Financial Statements, included in Part I, Item 1: Financial Information, in this Quarterly Report on Form 10-Q, incorporated by reference herein.

Inflation

Inflation can have an impact on our operating costs. A prolonged period of inflation could cause interest rates, fuel, equipment, wages, and other costs to increase, which would adversely affect our results of operations unless freight rates correspondingly increase. However, the effect of inflation has been minor in recent years.

Recently Issued Accounting Pronouncements

See Part I, Item 1: Financial Statements in this Quarterly Report on Form 10-Q, which is incorporated herein by reference, for the impact of recently issued accounting pronouncements on the Company's consolidated financial statements, as follows:

• Note 1 for recently issued accounting pronouncements the Company adopted in the quarter endedMarch 31, 2017.

• Note 2 for recently issued accounting pronouncements, not yet adopted by the Company as of March 31, 2017.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have exposure from variable interest rates, primarily related to our 2015 Agreement and 2015 RSA. These variable interest rates are impacted by changes in short-term interest rates. We primarily manage interest rate exposure through a mix of variable-rate debt (weighted average variable rate of 2.0% and 1.7% for the quarter endedMarch 31, 2017 and 2016, respectively). Assuming the current level of borrowings, a hypothetical one-percentage point increase in interest rates would increase our annual interest expense by $7.9 million.

We have commodity exposure with respect to fuel used in company-owned tractors. Increases in fuel prices would continue to raise our operating costs, even after applying fuel surcharge revenue. Historically, we have been able to recover a majority of fuel price increases from our customers in the form of fuel surcharges. The weekly average diesel price per gallon in the United States, as reported by the DOE, increased from an average of $2.083 per gallon for the quarter endedMarch 31, 2016 to an average of $2.568 per gallon for the quarter endedMarch 31, 2017. 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

Evaluation of Disclosure Controls and Procedures

Management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures and determined that as of March 31, 2017 our disclosure controls and procedures were effective at a reasonable assurance level to ensure that information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Change in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during the quarter ended March 31, 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Information about our legal proceedings is included in Note 11 of the notes to our consolidated financial statements, included in Part I, Item 1, in this Quarterly Report on Form 10-Q for the period ended March 31, 2017, and is incorporated by reference herein.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, the factors discussed in Part I, Item 1A, "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2016 should be carefully considered as these risk factors could materially affect our business, financial condition, future results and/or our ability to maintain compliance with our debt covenants. The risks described in our Form 10-K are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also adversely affect our business, financial condition, operating results and/or our ability to maintain compliance with our debt covenants.

Except as described below, there has been no material change in our risk factors as previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2016. For a detailed description of risk factors, refer to Part I, Item 1A, "Risk Factors", of our Annual Report on Form 10-K for the year ended December 31, 2016.

The proposed merger between Swift Transportation Company and Knight Transportation, Inc. may present certain risks to Swift’s business and operations.

On April 9, 2017, Swift Transportation Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Knight Transportation, Inc., an Arizona corporation (“Knight”). Pursuant to the terms of the Merger Agreement, which was approved unanimously by the boards of directors of Swift and Knight, Swift will conduct a 0.72 for 1.0 reverse stock split prior to the merger and existing Swift stockholders will retain their shares. Knight shareholders will receive 1.0 shares of Swift Transportation Company common stock in exchange for each share of Knight they hold. In addition, upon the closing of the merger, Swift will have a single class of common stock outstanding. Swift expects the transaction, which is subject to the adoption and approval of the Merger Agreement by Swift’s and Knight’s stockholders, to close in the third quarter of 2017.

The merger may present certain risks to Swift’s business and operations prior to the closing of the merger, including, among other things, the failure to consummate the proposed transaction or to make or take any filing or other action required to consummate such transaction on a timely matter or at all.

In addition, certain risks may continue to exist after the closing of the merger, including, among other things:

• the completion of the proposed transaction on anticipated terms and timing, including obtaining shareholder and regulatory approvals, anticipated tax treatment, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, future prospects, business and management strategies for the management, expansion and growth of the new combined company’s operations and other conditions to the completion of the merger;

• the ability of Knight and Swift to operate the business successfully and to achieve anticipated synergies;

• potential litigation relating to the proposed transaction that could be instituted against Knight, Swift or their respective directors;

• the risk that disruptions from the proposed transaction will harm Knight’s or Swift’s business, including current plans and operations;

• the ability of Knight and Swift to retain and hire key personnel;

• potential adverse reactions or changes to business relationships resulting from the announcement or completion of the merger;

• uncertainty as to the long-term value of the combined company’s common stock;

• continued availability of capital and financing and rating agency actions;

• legislative, regulatory and economic developments; and

• unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as management’s response to any of the aforementioned factors.

Consequences of material differences in results as compared with those expected from the merger could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on Knight, Swift, and Knight-Swift financial condition, results of operations, credit rating or liquidity.

As of March 31, 2017, the Company's fleet of revenue equipment included 18,656 tractors (comprised of 14,017 company tractors and 4,639 owner-operator tractors), 63,207 trailers, and 9,130 intermodal containers. The Company’s four reportable segments are Truckload, Dedicated, Refrigerated (formerly "Swift Refrigerated"), and Intermodal.

Subsequent Events

Merger

On April 10, 2017, Swift announced an all-stock merger agreement with Knight Transportation, Inc. ("Knight"), which was unanimously approved by the boards of directors of Swift and Knight and is expected to close during the quarter ended September 30, 2017. The combined company will be named Knight-Swift Transportation Holdings Inc. ("Knight-Swift"). Knight is expected to be the accounting acquirer. Under the terms of the definitive agreement each Swift share will convert into 0.72 shares of Knight-Swift by means of a reverse stock split. Each share of Knight will be exchanged for one Knight-Swift share. Based on the $30.65 closing price of Knight shares on April 7, 2017, the last trading day prior to the announcement, the implied value per share of Swift is $22.07. Upon closing of the transaction, Swift stockholders will own approximately 54.0% and Knight stockholders will own approximately 46.0% of the combined company. Based on Knight’s closing share price on April 7, 2017, the number of combined company shares expected to be outstanding after closing and the combined net debt of Swift and Knight as of December 31, 2016, the combined company would have an implied enterprise value of approximately $6.0 billion.

The merger agreement provides for certain termination rights for both Knight and the Company. Upon termination of the merger agreement under certain specified circumstances, the Company may be required to pay Knight a termination fee of $89.1 million and Knight may be required to pay the Company a termination fee of $75.3 million. In addition, if the merger agreement is terminated because of a failure of either Knight’s or the Company’s stockholders to approve the transactions contemplated by the merger agreement, the other party may be required to reimburse transaction expenses up to $10.0 million.

Legal Settlement

On April 13, 2017, the Company proposed a tentative settlement arrangement with regard to certain litigation in the Refrigerated segment, which was finalized on April 28, 2017, subject to final court approval. As such, the Company increased its legal accrual by $11.7 million for the quarter ended March 31, 2017.

Seasonality

In the truckload industry, results of operations generally show a seasonal pattern. As customers ramp up for the year-end holiday season, the late third quarter and fourth quarter have historically been the Company's strongest volume periods. As customers reduce shipments after the winter holiday season, the first quarter has historically been a lower-volume quarter than the other three quarters. In recent years, the macro consumer buying patterns combined with shippers’ supply chain management, which historically contributed to the fourth quarter "peak" season, continued to evolve. As a result, the Company's fourth quarter 2016, 2015, and 2014 volumes were more evenly distributed throughout the quarter, rather than peaking early in the quarter. In the eastern and mid-western United States, and to a lesser extent in the western United States, the Company's equipment utilization typically declines and operating expenses generally increase during the winter season. This tends to be attributed to declines in fuel efficiency from engine idling and increases in accident frequency, claims, and equipment repairs from severe weather. The Company's revenue is directly related to shippers' available working days. As such, curtailed operations and vacation shutdowns around the holidays may affect the Company's revenue. From time to time, the Company also suffers short-term impacts from severe weather and similar events, such as tornadoes, hurricanes, blizzards, ice storms, floods, fires, earthquakes, and explosions that could add volatility to, or harm, the Company's results of operations.

Basis of Presentation

The consolidated financial statements and footnotes included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and footnotes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2016. The consolidated financial statements include the accounts of Swift Transportation Company and its wholly-owned subsidiaries. In management's opinion, these consolidated financial statements were prepared in accordance with GAAP and include all adjustments necessary for the fair presentation of the periods presented.

Changes in Presentation

Segment Reorganization— During the quarter ended March 31, 2017, the Company reorganized its reportable segments to reflect management’s revised reporting structure of its Dedicated and Refrigerated (formerly “Swift Refrigerated”) reportable segments.  In association with the reorganization, the operations of the Company's dedicated grocery line of business, which were previously reported within the Company’s Dedicated segment, are now reported within the Company's Refrigerated segment.  This resulted in all temperature-controlled lines of business reporting under the Refrigerated segment. Prior periods have been retrospectively adjusted to align with the current period presentation.

Recently Adopted Accounting Pronouncement — In March 2016, FASB issued ASU 2016-09, Improvements to Employee Share-based Payment Accounting, which amended ASC 718, Compensation – Stock Compensation. The amendments in this ASU are intended to simplify various aspects of accounting for stock-based compensation, including income tax consequences, classification of awards as equity or liability, as well as classification of activities within the statement of cash flows.  For public business entities, the amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2016, and the interim periods within those fiscal years. 

The Company adopted this guidance during the quarter ended March 31, 2017. The amendments that affected the Company's financial statements are discussed below.

• Accounting for Income Tax Benefits/Deficiencies: All excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) should be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Modified retrospective application is required, by means of a cumulative-effect adjustment to equity.

Upon adoption, the Company reclassified approximately$16.8 million in historical net tax benefit/deficiency amounts previously recorded within "Additional paid-in capital" into "Accumulated deficit." Starting January 1, 2017, tax benefit/deficiency amounts are recorded in "Income tax expense" in the consolidated income statements.

• Classification of Excess Tax Benefits on the Statement of Cash Flows: Excess tax benefits should be classified along with other income tax cash flows as an operating activity. Application is permitted to be prospective or retrospective.

GAAP previously required classification within cash flows from financing activities. The Company retrospectively adjusted the statement of cash flows for the quarter ended March 31, 2016 to align with the current period presentation by increasing cash flows from operating activities by $0.1 million and correspondingly decreasing cash flows from financing activities by $0.1 million, reflecting the amount of excess tax benefits previously presented for that period.

• Forfeitures: An entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (prior GAAP) or account for forfeitures when they occur. Modified retrospective application is required, by means of a cumulative-effect adjustment to equity.

Upon adoption, the Company transitioned to accounting for forfeitures when they occur. This resulted in approximately a $0.4 million (net of income tax) cumulative-effect adjustment to retained earnings/accumulated deficit to catch-up the previously unrecognized stock-based compensation associated with historical assumed forfeiture rates. Starting January 1, 2017, forfeitures are recorded as adjustments to stock-based compensation as they occur.

• Classification of Employee Taxes Paid on the Statement of Cash Flows When an Employer Withholds Shares for Tax-withholding purposes: Cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. Retrospective application is required.

In 2016, the Company began allowing certain members of management to have shares withheld for taxes when their restricted stock awards and performance units vest. As such, upon adopting the amendments in this ASU, the Company reclassified the amounts out of cash flows from operating activities and into cash flows from financing activities for the quarter ended March 31, 2016 to align with the current period presentation. For the quarter-ended March 31, 2016, the amount was approximately$0.3 million.

____________

(1) Management is in the diagnostic phase of assessing the financial and business impacts of implementing ASC Topic 606, Revenue from Contracts with Customers, including identifying revenue sources within the Company's lines of business, reviewing a sample of contracts, and developing a preliminary assessment. Based upon these preliminary procedures, management anticipates that the following key considerations will impact the Company's accounting and reporting under the new standard:

• identification of what constitutes a contract in Swift's business practices,

• variability in individual contracts, such as customer-specific terms that may vary from the master agreement,

• principal versus agent determinations,

• timing of revenue recognition (for example, point-in-time versus over time and/or accelerated versus deferred),

• single versus multiple performance obligations,

• new/changed estimates and management judgments (for example, system estimation of in-transit accruals versus manual estimation),

• disaggregation of revenue by category within segments, and

• others.

Management expects that there will also be changes in sales, contracting, accounting, reporting, tax, debt covenants, and other business processes, policies, and controls, as a result of implementing ASC Topic 606. The Company is currently implementing a new ERP system and transacting a merger (as discussed in Note 1), which will also affect the implementation process.

Based on the information currently available from the diagnostic phase, management cannot yet determine the quantitative impact on the financial statements; however, the impact is expected to be immaterial (potentially with changes only to the timing of revenue recognition between reportable periods, as well as changes in the requirements for accounting policy and other new disclosures). The financial impact has not yet been quantified. The Company is transitioning into the design and planning phase of implementing ASC Topic 606. Since management is continuing to evaluate the impact of ASC Topic 606, disclosures around their preliminary assessments are subject to change.

Income Taxes

Income Taxes

Effective Tax Rate — The effective tax rate for the quarter endedMarch 31, 2017 was 31.3%, which was lower than management's expectation of 36.0%. The difference was primarily due to certain benefits relating to stock compensation deductions due to the Company's adoption of ASU 2016-09, partially offset by capitalized transaction costs relating to the merger with Knight recognized as discrete items in the quarter. Refer to Note 1 for further details regarding the Company's adoption of ASU 2016-09 and the merger with Knight.

The effective tax rate for the quarter endedMarch 31, 2016 was 29.8%, which was lower than management's expectation of 38.0%. The difference was primarily due to certain income tax credits received by the Company's foreign subsidiary and a reduction in the uncertain tax position reserve, recognized as discrete items in the quarter.

Interest and Penalties — Accrued interest and penalties related to unrecognized tax benefits as of March 31, 2017 and December 31, 2016 were approximately $0.4 million and $0.4 million, respectively. The Company does not anticipate a decrease of unrecognized tax benefits during the next twelve months.

Tax Examinations — Certain of the Company’s subsidiaries are currently under examination by the Internal Revenue Service and various state jurisdictions for tax years ranging from 2012 through 2015. At the completion of these examinations, management does not expect any adjustments that would have a material impact on the Company’s effective tax rate. Years subsequent to 2012 remain subject to examination.

Accounts Receivable Securitization

Accounts Receivable Securitization

On December 10, 2015, SRCII, a wholly-owned subsidiary of the Company, entered into the 2015 RSA, which further amended the 2013 RSA. The parties to the 2015 RSA include SRCII as the seller, Swift Transportation Services, LLC as the servicer, the various conduit purchasers, the various related committed purchasers, the various purchaser agents, the various letters of credit participants, and PNC Bank, National Association as the issuing bank of letters of credit and as administrator. Pursuant to the 2015 RSA, the Company's receivable originator subsidiaries sell, on a revolving basis, undivided interests in all of their eligible accounts receivable to SRCII. In turn, SRCII sells a variable percentage ownership interest in the eligible accounts receivable to the various purchasers. The facility qualifies for treatment as a secured borrowing under ASC Topic 860, Transfers and Servicing. As such, outstanding amounts are classified as liabilities on the Company’s consolidated balance sheets. Refer to Note 14 for information regarding the fair value of the 2015 RSA.

As of March 31, 2017 and December 31, 2016, interest accrued on the aggregate principal balance at a rate of 1.5% and 1.3%, respectively. Program fees and unused commitment fees are recorded in "Interest expense" in the consolidated income statements. The Company incurred program fees of $1.4 million and $0.9 million related to the 2015 RSA during the quarter endedMarch 31, 2017 and 2016, respectively.

The 2015 RSA is subject to customary fees and contains various customary affirmative and negative covenants, representations and warranties, and default and termination provisions. Collections on the underlying receivables by the Company are held for the benefit of SRCII and the Purchasers in the facility and are unavailable to satisfy claims of the Company and its subsidiaries.

____________

(1) The interest rate margin for the Term Loan A and Revolver is based on the Company's consolidated leverage ratio. As of March 31, 2017, interest accrued at 2.38% on the Term Loan A and 2.39% on the Revolver. As of December 31, 2016, interest accrued at 2.18% on the Term Loan A and 2.18% on the Revolver.

(2) The commitment fee for the unused portion of the Revolver is based on the Company's consolidated leverage ratio and ranges from 0.25% to 0.35%. As of March 31, 2017, commitment fees on the unused portion of the Revolver accrued at 0.25% and outstanding letter of credit fees accrued at 1.50%. As of December 31, 2016, commitment fees on the unused portion of the Revolver accrued at 0.25% and outstanding letter of credit fees accrued at 1.50%.

(3) Commencing in March 2017, the minimum required quarterly payment amount on the Term Loan A is $12.3 million, at which it would remain until final maturity. However, as of January 2017, the Company has voluntarily prepaid all minimum quarterly principal payments through final maturity.

The Revolver and Term Loan A of the 2015 Agreement contain certain financial covenants with respect to a maximum leverage ratio and a minimum consolidated interest coverage ratio. The 2015 Agreement provides flexibility regarding the use of proceeds from asset sales, payment of dividends, stock repurchases, and equipment financing. In addition to the financial covenants, the 2015 Agreement includes customary events of default, including a change in control default and certain affirmative and negative covenants, including, but not limited to, restrictions, subject to certain exceptions, on incremental indebtedness, asset sales, certain restricted payments (including dividends and stock repurchases), certain incremental investments or advances, transactions with affiliates, engagement in additional business activities, and prepayment of certain other indebtedness. The anticipated merger with Knight discussed in Note 1 is not expected to be deemed a change in control, as defined in the 2015 Agreement.

Borrowings under the 2015 Agreement are secured by substantially all of the assets of the Company and are guaranteed by Swift Transportation Company, IEL, Central Refrigerated Transportation, LLC and its subsidiaries, and Swift Transportation Co., LLC and its domestic subsidiaries (other than its captive insurance subsidiaries, driver academy subsidiary, and its bankruptcy-remote special purpose subsidiary).

Leases [Abstract]

Leases

Leases

The Company finances a portion of its revenue equipment under capital and operating leases and certain terminals under operating leases.

Capital Leases (as Lessee) — The Company’s capital leases are typically structured with balloon payments at the end of the lease term equal to the residual value the Company is contracted to receive from certain equipment manufacturers upon sale or trade back to the manufacturers. If the Company does not receive proceeds of the contracted residual value from the manufacturer, the Company is still obligated to make the balloon payment at the end of the lease term. Certain leases contain renewal or fixed price purchase options. The present value of obligations under capital leases is included under "Current portion of capital lease obligations" and "Capital lease obligations, less current portion" in the consolidated balance sheets. As of March 31, 2017, the leases were collateralized by revenue equipment with a cost of $296.0 million and accumulated amortization of $91.3 million. As of December 31, 2016, the leases were collateralized by revenue equipment with a cost of $319.8 million and accumulated amortization of $97.0 million. Amortization of equipment under capital leases is included in "Depreciation and amortization of property and equipment" in the Company’s consolidated income statements.

Operating Leases (as Lessee) — Rent expense related to operating leases was $55.7 million and $56.3 million for the quarter endedMarch 31, 2017 and 2016, respectively.

Purchase Commitments

As of March 31, 2017, the Company's outstanding commitments to acquire revenue equipment were as follows:

• remainder of 2017: $277.0 million ($195.4 million of which were tractor commitments), and

• thereafter: none.

The Company typically has the option to cancel tractor purchase orders with 60 to 90 days' notice prior to the scheduled production, although there is a certain group of tractors we are committed to purchase in 2017 that cannot be canceled (even with advance notice). The notice period to cancel currently committed tractor purchase orders has lapsed for 78.0% of the total tractor commitments outstanding as of March 31, 2017. Purchases are expected to be financed by the combination of operating leases, capital leases, debt, proceeds from sales of existing equipment, and cash flows from operations.

As of March 31, 2017, the Company's outstanding purchase commitments to acquire facilities and non-revenue equipment were as follows:

• remainder of 2017: $10.7 million

• 2018 and 2019: $8.8 million, and

• thereafter: $3.9 million.

Factors such as potential future terminal expansions and changes in information technology infrastructure may change the amount of such expenditures.

Contingencies and Legal Proceedings

Contingencies and Legal Proceedings

Accounting Policy

The Company is involved in certain claims and pending litigation primarily arising in the normal course of business. The majority of these claims relate to workers' compensation, auto collision and liability, physical damage, and cargo damage. The Company accrues for the uninsured portion of claims losses and the gross amount of other losses when the likelihood of the loss is probable and the amount of the loss is reasonably estimable. These accruals are based on management's best estimate within a possible range of loss. When there is no amount within the range of loss that appears to be a better estimate than any other amount, then management accrues to the low end of the range. Legal fees are expensed as incurred.

When it is reasonably possible that exposure exists in excess of the related accrual (which could be no accrual), management discloses an estimate of the possible loss or range of loss, unless an estimate cannot be determined.

If the likelihood of a loss is remote, the Company does not accrue for the loss. However if the likelihood of a loss is remote, but it is at least reasonably possible that one or more future confirming events may materially change management's estimate within twelve months from the date of the financial statements, management discloses an estimate of the possible loss or range of loss, unless an estimate cannot be determined.

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.

For the matters below, an estimate of the possible loss or range of loss cannot be determined for certain cases because, among other reasons, (1) the proceedings are in various stages that do not allow for assessment; (2) damages have not been sought; (3) damages are unsupported and/or exaggerated; (4) there is uncertainty as to the outcome of pending appeals; and/or (5) there are significant factual issues to be resolved.

Based on currently available information, and in certain cases, advice of outside counsel, management does not believe that loss contingencies arising from pending matters will have a material adverse effect on the Company's overall financial position, after taking into consideration any existing accruals. However, actual outcomes could be material to the Company's operating results or liquidity for any particular period.

The original trial court's decision was to deny class certification of the owner-operators, which was reversed and reinstated several times by various courts prior to 2016. The class is currently certified, based on an appellate court's decision from July 2016. The Company filed a petition for review with the Arizona Supreme Court in August 2016, which was denied in January 2017. The matter will now proceed in the Maricopa County Superior Court. The final disposition of the matter and impact to the Company cannot be determined at this time. The likelihood that a loss has been incurred is remote.
Ninth Circuit Owner-operator Misclassification Class Action
The putative class alleges that the Company misclassified owner-operators as independent contractors in violation of the FLSA and various state laws, and that such owner-operators should be considered employees.

Recent Developments and Current Status
For several years, the parties have been arguing over the proper venue in which to proceed. The plaintiffs argue that they signed contracts of employment, thus exempting them from arbitration under the Federal Arbitration Act, and claim that their case should be heard in court by a judge. The Company takes the position that these individuals signed independent contractor agreements and therefore can properly be required to submit their claims to arbitration. In January 2017, the district court issued an order finding that the plaintiffs had signed contracts of employment and thus the case could properly proceed in court. The Company has appealed this decision to the Ninth Circuit and the district court stayed the proceedings, pending resolution of the appeal. The Company intends to vigorously defend against any proceedings. The final disposition of the matter and impact to the Company cannot be determined at this time. The likelihood that a loss has been incurred is remote.

Utah Collective and Individual Arbitration
The plaintiffs allege that the Central Parties (defined below) misclassified owner-operator drivers as independent contractors and were therefore liable to these drivers for minimum wages and other employee benefits under the FLSA. The complaint also alleges a federal forced labor claim under U.S.C. §1589 and §1595, as well as fraud and other state-law claims.

Recent Developments and Current Status
In June 2016, mediation commenced, but there was ultimately no settlement of the matter. In October 2016, the arbitrator ruled that approximately 1,300 Central Refrigerated Service, Inc. drivers were improperly classified as independent contractors, when they should have been classified and compensated as employees. The arbitrator ruled that damages could ultimately be assessed in a collective proceeding and denied the Company's motion to decertify the collective proceeding. Based upon the October 2016 arbitration ruling, the Company increased its legal accrual related to this matter for the quarter ended September 30, 2016. On April 14, 2017, the Company proposed a tentative settlement arrangement, which was finalized by and between the parties on April 28, 2017, subject to final court approval. As such, the Company increased its legal accrual again for the quarter ended March 31, 2017. The likelihood that a loss has been incurred is probable.

Other Contingencies

Demand for Inspection of Books and Records and Stockholder Derivative Lawsuit —During2016, the Company received several shareholder demands requesting to inspect the Company's books and records, pursuant to Section 220 of the Delaware General Corporation Law ("Section 220").  The demands relate to the shareholders' alleged investigation pertaining to whether the Board and Jerry Moyes have breached their fiduciary duties with respect to matters that have been publicly disclosed concerning the Company's securities trading policy, limitations on the pledging of Company stock on margin, share repurchases, the status of Board members as independent directors and other related matters. The Company has responded to the shareholders' requests received thus far. On February 9, 2017, a civil lawsuit was filed in the Court of Chancery of the State of Delaware (captioned as: Shiva Stein derivatively on behalf of Swift Transportation Company v. Jerry Moyes et al. and Swift Transportation Company as nominal defendant (the "Complaint")). The Complaint, initially filed as a confidential filing, is a purported derivative action alleging that the individual members of the Company's Board breached their fiduciary duties related to the Company's administration of its Securities Trading Policy and certain compensation actions related to Mr. Moyes.

In February 2017, the Company received a shareholder demand under Section 220 for books and records related to an alleged investigation into whether the Board breached its fiduciary duties in connection with the September 8, 2016 retirement agreement between the Company and Mr. Moyes. The Company is in the process of responding to this request.

Any future disposition or resolution of these matters cannot be determined at this time.

Environmental

The Company's tractors and trailers are involved in motor vehicle accidents, and experience damage, mechanical failures, and cargo issues as an incidental part of its normal course of operations.  From time to time, these matters result in the discharge of diesel fuel, motor oil, or other hazardous materials into the environment.  Depending on local regulations and who is determined to be at fault, the Company is sometimes responsible for the clean-up costs associated with these discharges.  As of March 31, 2017, the Company's estimate for its total legal liability for all such clean-up and remediation costs was approximately $0.3 million in the aggregate for all current and prior year claims.

Jerry Moyes' Retirement

Jerry Moyes' Retirement

In conjunction with the Company's September 8, 2016 announcement that Jerry Moyes would retire from his position as Chief Executive Officer effective December 31, 2016, the Company entered into an agreement with Mr. Moyes to memorialize the terms of his retirement. The Company contracted with Mr. Moyes to serve as a non-employee consultant from January 1, 2017 through December 31, 2019, during which time the Company will pay Mr. Moyes a monthly consulting fee of $0.2 million in cash. Additionally, the Company modified the vesting terms and forfeiture conditions of Mr. Moyes' previously-granted equity awards. As a result of the terms of the agreement, the Company incurred a one-time expense in September 2016 of $7.1 million, consisting of $6.8 million in accrued consulting fees and $0.3 million for the impact of the equity award modifications. The amounts were included in "Salaries, wages, and employee benefits" within the non-reportable segments' income statement.

The following schedule is a rollforward of the accrued liability for the consulting fees:

	March 31, 2017

Segment Information

The Company’s four reportable operating segments are Truckload, Dedicated, Refrigerated (formerly "Swift Refrigerated"), and Intermodal. See Note 1 regarding the reorganization of the Company's Dedicated and Refrigerated segments.

Truckload — The Truckload segment consists of one-way movements over irregular routes throughout the United States, Mexico, and Canada. This service utilizes both company and owner-operator tractors with dry van, flatbed, and other specialized trailing equipment.

Dedicated — Through the Dedicated segment, the Company devotes use of equipment to specific customers and offers tailored solutions under long-term contracts. This segment utilizes dry van, flatbed, and other specialized trailing equipment.

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

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

Non-reportable Segments — The non-reportable segments include the Company's logistics and freight brokerage services, as well as support services that its subsidiaries provide to customers and owner-operators, including repair and maintenance shop services, equipment leasing, and insurance. Intangible amortization related to the 2007 Transactions, certain legal settlements and reserves, and certain other corporate expenses are also included in the non-reportable segments.

Intersegment Eliminations — Certain operating segments provide transportation and related services for other affiliates outside their reportable segment. Revenues for such services are based on negotiated rates, which we believe approximate fair value, 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 our consolidated results.

Accounting Policies [Abstract]

Contingencies and Legal Proceedings, Policy

The Company is involved in certain claims and pending litigation primarily arising in the normal course of business. The majority of these claims relate to workers' compensation, auto collision and liability, physical damage, and cargo damage. The Company accrues for the uninsured portion of claims losses and the gross amount of other losses when the likelihood of the loss is probable and the amount of the loss is reasonably estimable. These accruals are based on management's best estimate within a possible range of loss. When there is no amount within the range of loss that appears to be a better estimate than any other amount, then management accrues to the low end of the range. Legal fees are expensed as incurred.

When it is reasonably possible that exposure exists in excess of the related accrual (which could be no accrual), management discloses an estimate of the possible loss or range of loss, unless an estimate cannot be determined.

If the likelihood of a loss is remote, the Company does not accrue for the loss. However if the likelihood of a loss is remote, but it is at least reasonably possible that one or more future confirming events may materially change management's estimate within twelve months from the date of the financial statements, management discloses an estimate of the possible loss or range of loss, unless an estimate cannot be determined.

(1) Management is in the diagnostic phase of assessing the financial and business impacts of implementing ASC Topic 606, Revenue from Contracts with Customers, including identifying revenue sources within the Company's lines of business, reviewing a sample of contracts, and developing a preliminary assessment. Based upon these preliminary procedures, management anticipates that the following key considerations will impact the Company's accounting and reporting under the new standard:

• identification of what constitutes a contract in Swift's business practices,

• variability in individual contracts, such as customer-specific terms that may vary from the master agreement,

• principal versus agent determinations,

• timing of revenue recognition (for example, point-in-time versus over time and/or accelerated versus deferred),

• single versus multiple performance obligations,

• new/changed estimates and management judgments (for example, system estimation of in-transit accruals versus manual estimation),

• disaggregation of revenue by category within segments, and

• others.

Management expects that there will also be changes in sales, contracting, accounting, reporting, tax, debt covenants, and other business processes, policies, and controls, as a result of implementing ASC Topic 606. The Company is currently implementing a new ERP system and transacting a merger (as discussed in Note 1), which will also affect the implementation process.

Based on the information currently available from the diagnostic phase, management cannot yet determine the quantitative impact on the financial statements; however, the impact is expected to be immaterial (potentially with changes only to the timing of revenue recognition between reportable periods, as well as changes in the requirements for accounting policy and other new disclosures). The financial impact has not yet been quantified. The Company is transitioning into the design and planning phase of implementing ASC Topic 606. Since management is continuing to evaluate the impact of ASC Topic 606, disclosures around their preliminary assessments are subject to change.

Schedule of Loss Contingencies by Contingency [Table Text Block]

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.

For the matters below, an estimate of the possible loss or range of loss cannot be determined for certain cases because, among other reasons, (1) the proceedings are in various stages that do not allow for assessment; (2) damages have not been sought; (3) damages are unsupported and/or exaggerated; (4) there is uncertainty as to the outcome of pending appeals; and/or (5) there are significant factual issues to be resolved.

Based on currently available information, and in certain cases, advice of outside counsel, management does not believe that loss contingencies arising from pending matters will have a material adverse effect on the Company's overall financial position, after taking into consideration any existing accruals. However, actual outcomes could be material to the Company's operating results or liquidity for any particular period.

Arizona Owner-operator Class Action

Plaintiff(s)	Defendant(s)		Date instituted	Court or agency currently pending in
Leonel Garza (1)	Swift Transportation Co., Inc.		January 30, 2004	Maricopa County Superior Court
Recent Developments and Current Status
The original trial court's decision was to deny class certification of the owner-operators, which was reversed and reinstated several times by various courts prior to 2016. The class is currently certified, based on an appellate court's decision from July 2016. The Company filed a petition for review with the Arizona Supreme Court in August 2016, which was denied in January 2017. The matter will now proceed in the Maricopa County Superior Court. The final disposition of the matter and impact to the Company cannot be determined at this time. The likelihood that a loss has been incurred is remote.
Ninth Circuit Owner-operator Misclassification Class Action
The putative class alleges that the Company misclassified owner-operators as independent contractors in violation of the FLSA and various state laws, and that such owner-operators should be considered employees. The lawsuit also raises certain related issues with respect to the lease agreements that certain owner-operators have entered into with IEL.
Plaintiff(s)	Defendant(s)		Date instituted	Court or agency currently pending in
Joseph Sheer, Virginia Van Dusen, Jose Motolinia, Vickii Schwalm, Peter Wood (1)	Swift Transportation Co., Inc., Interstate Equipment Leasing, Inc., Jerry Moyes, and Chad Killebrew		December 22, 2009	Unites States District Court of Arizona and Ninth Circuit Court of Appeals
Recent Developments and Current Status
For several years, the parties have been arguing over the proper venue in which to proceed. The plaintiffs argue that they signed contracts of employment, thus exempting them from arbitration under the Federal Arbitration Act, and claim that their case should be heard in court by a judge. The Company takes the position that these individuals signed independent contractor agreements and therefore can properly be required to submit their claims to arbitration. In January 2017, the district court issued an order finding that the plaintiffs had signed contracts of employment and thus the case could properly proceed in court. The Company has appealed this decision to the Ninth Circuit and the district court stayed the proceedings, pending resolution of the appeal. The Company intends to vigorously defend against any proceedings. The final disposition of the matter and impact to the Company cannot be determined at this time. The likelihood that a loss has been incurred is remote.

Utah Collective and Individual Arbitration
The plaintiffs allege that the Central Parties (defined below) misclassified owner-operator drivers as independent contractors and were therefore liable to these drivers for minimum wages and other employee benefits under the FLSA. The complaint also alleges a federal forced labor claim under U.S.C. §1589 and §1595, as well as fraud and other state-law claims.
Plaintiff(s)	Defendant(s)	Date instituted	Court or agency currently pending in
Gabriel Ciluffo, Kevin Shire, and Bryan Ratterree (1)	Central Refrigerated Service, Inc., Central Leasing, Inc., Jon Isaacson, and Jerry Moyes (the "Central Parties"), as well as Swift Transportation Company	June 1, 2012	American Arbitration Association
Recent Developments and Current Status
In June 2016, mediation commenced, but there was ultimately no settlement of the matter. In October 2016, the arbitrator ruled that approximately 1,300 Central Refrigerated Service, Inc. drivers were improperly classified as independent contractors, when they should have been classified and compensated as employees. The arbitrator ruled that damages could ultimately be assessed in a collective proceeding and denied the Company's motion to decertify the collective proceeding. Based upon the October 2016 arbitration ruling, the Company increased its legal accrual related to this matter for the quarter ended September 30, 2016. On April 14, 2017, the Company proposed a tentative settlement arrangement, which was finalized by and between the parties on April 28, 2017, subject to final court approval. As such, the Company increased its legal accrual again for the quarter ended March 31, 2017. The likelihood that a loss has been incurred is probable.

Melvin Banks (1)	Central Refrigerated Service, Inc.		March 18, 2015	United States District Court for the District of Utah
Recent Developments and Current Status
The first phase of discovery, regarding potential for identifying and certifying a class of affected job applicants, has been completed. The parties recently completed class certification briefing and the Company filed a Motion for Summary Judgment. Rulings on these Motions are pending from the court. The Company retains all of its defenses against liability and damages. Additionally, the Company intends to vigorously defend against the merits of the claims and to challenge certification. The final disposition of the matter and the impact on the Company cannot be determined at this time. The likelihood that a loss has been incurred is remote.

California Class and Collective Action for Pre-employment Physical Testing
The plaintiff alleges that pre-employment tests of physical strength administered by a third party on behalf of Central Refrigerated Service, Inc. had an unlawfully discriminatory impact on female applicants and applicants over the age of 40.

Recently Issued Accounting Pronouncements [Line Items]
Accounting pronouncement description	The new standard requires lessees to recognize assets and liabilities arising from both operating and financing leases on the balance sheet. Lessor accounting for leases is largely unaffected by the new guidance.
Adoption date and method	January 2019, Modified retrospective
Financial statement impact	Currently under evaluation; expected to be material, but not yet quantifiable.

[1] (1)Management is in the diagnostic phase of assessing the financial and business impacts of implementing ASC Topic 606, Revenue from Contracts with Customers, including identifying revenue sources within the Company's lines of business, reviewing a sample of contracts, and developing a preliminary assessment. Based upon these preliminary procedures, management anticipates that the following key considerations will impact the Company's accounting and reporting under the new standard: •identification of what constitutes a contract in Swift's business practices,•variability in individual contracts, such as customer-specific terms that may vary from the master agreement,•principal versus agent determinations,•timing of revenue recognition (for example, point-in-time versus over time and/or accelerated versus deferred),•single versus multiple performance obligations, •new/changed estimates and management judgments (for example, system estimation of in-transit accruals versus manual estimation), •disaggregation of revenue by category within segments, and•others.Management expects that there will also be changes in sales, contracting, accounting, reporting, tax, debt covenants, and other business processes, policies, and controls, as a result of implementing ASC Topic 606. The Company is currently implementing a new ERP system and transacting a merger (as discussed in Note 1), which will also affect the implementation process.Based on the information currently available from the diagnostic phase, management cannot yet determine the quantitative impact on the financial statements; however, the impact is expected to be immaterial (potentially with changes only to the timing of revenue recognition between reportable periods, as well as changes in the requirements for accounting policy and other new disclosures). The financial impact has not yet been quantified. The Company is transitioning into the design and planning phase of implementing ASC Topic 606. Since management is continuing to evaluate the impact of ASC Topic 606, disclosures around their preliminary assessments are subject to change.

Loss Contingency, Allegations	The plaintiffs generally allege one or more of the following: that the Company 1) failed to pay the California minimum wage; 2) failed to provide proper meal and rest periods; 3) failed to timely pay wages upon separation from employment; 4) failed to pay for all hours worked; 5) failed to pay overtime; 6) failed to properly reimburse work-related expenses; and 7) failed to provide accurate wage statements.
Loss Contingency, Opinion of Counsel	Before and during 2016, the Rudsell, Peck, Peck PAGA, Mares, McKinsty, and Nilsen complaints were stayed, pending resolution of earlier-filed cases. In May 2016, the Burnell plaintiffs were denied class certification. Their subsequent petition to appeal the decertification order was also denied. Following the Burnell plaintiffs' failure to certify the class, the stays on certain cases were lifted. The Peck case is currently in discovery. The parties in the Mares and McKinsty cases are currently completing class certification briefing. Based on the current procedural nature of the cases, the final disposition of the matter and impact to the Company cannot be determined at this time. The likelihood that a loss has been incurred is remote.

Arizona Owner-operator Class Actions [Member] | Owner-Operator Matters [Member]
Loss Contingencies [Line Items]
Loss Contingency, Allegations	The putative class alleges that the Company improperly compensated owner-operators (later expanding the class to include employee drivers) using the contracted and industry standard remuneration based upon dispatched miles, instead of using a method of calculating mileage that the plaintiffs allege would be more accurate.
Loss Contingency, Opinion of Counsel	The original trial court's decision was to deny class certification of the owner-operators, which was reversed and reinstated several times by various courts prior to 2016. The class is currently certified, based on an appellate court's decision from July 2016. The Company filed a petition for review with the Arizona Supreme Court in August 2016, which was denied in January 2017. The matter will now proceed in the Maricopa County Superior Court. The final disposition of the matter and impact to the Company cannot be determined at this time. The likelihood that a loss has been incurred is remote.
Ninth Circuit Owner-operator Misclassification Class Actions [Member] | Owner-Operator Matters [Member]
Loss Contingencies [Line Items]
Loss Contingency, Allegations	The putative class alleges that the Company misclassified owner-operators as independent contractors in violation of the FLSA and various state laws, and that such owner-operators should be considered employees. The lawsuit also raises certain related issues with respect to the lease agreements that certain owner-operators have entered into with IEL.
Loss Contingency, Opinion of Counsel	For several years, the parties have been arguing over the proper venue in which to proceed. The plaintiffs argue that they signed contracts of employment, thus exempting them from arbitration under the Federal Arbitration Act, and claim that their case should be heard in court by a judge. The Company takes the position that these individuals signed independent contractor agreements and therefore can properly be required to submit their claims to arbitration. In January 2017, the district court issued an order finding that the plaintiffs had signed contracts of employment and thus the case could properly proceed in court. The Company has appealed this decision to the Ninth Circuit and the district court stayed the proceedings, pending resolution of the appeal. The Company intends to vigorously defend against any proceedings. The final disposition of the matter and impact to the Company cannot be determined at this time. The likelihood that a loss has been incurred is remote.

Utah Collective and Individual Arbitration [Member]
Loss Contingencies [Line Items]
Loss Contingency, Opinion of Counsel	In June 2016, mediation commenced, but there was ultimately no settlement of the matter. In October 2016, the arbitrator ruled that approximately 1,300 Central Refrigerated Service, Inc. drivers were improperly classified as independent contractors, when they should have been classified and compensated as employees. The arbitrator ruled that damages could ultimately be assessed in a collective proceeding and denied the Company's motion to decertify the collective proceeding. Based upon the October 2016 arbitration ruling, the Company increased its legal accrual related to this matter for the quarter ended September 30, 2016. On April 14, 2017, the Company proposed a tentative settlement arrangement, which was finalized by and between the parties on April 28, 2017, subject to final court approval. As such, the Company increased its legal accrual again for the quarter ended March 31, 2017. The likelihood that a loss has been incurred is probable.

Loss Contingency, Opinion of Counsel	Litigation is at a very preliminary stage and no trial date has been set. Additionally, there is a motion for class certification pending, for which the Company is preparing a response. The Company intends to vigorously defend against the merits of the plaintiff's claims and to oppose certification of any class of plaintiffs.
