The accompanying unaudited consolidated financial statements of Universal Logistics Holdings, Inc. and its wholly-owned subsidiaries (collectively, “Universal” or the “Company”) have been prepared by the Company’s management. In the opinion of management, the unaudited consolidated financial statements include all normal recurring adjustments necessary to present fairly the information required to be set forth therein. All intercompany transactions and balances have been eliminated in consolidation. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted from these statements pursuant to such rules and regulations and, accordingly, should be read in conjunction with the consolidated financial statements as of December 31, 2017 and 2016 and for each of the years in the three-year period ended December 31, 2017 included in the Company’s Form 10-K filed with the Securities and Exchange Commission. The preparation of the consolidated financial statements requires the use of management’s estimates. Actual results could differ from those estimates. Our fiscal year ends on December 31 and consists of four quarters, each with thirteen weeks. The Company made certain immaterial reclassifications to items in its prior financial statements so that their presentation is consistent with the format in the financial statements for the period ended September 29, 2018. These reclassifications, however, had no effect on reported consolidated net income, comprehensive income, earnings per common share, cash flows, total assets or shareholders’ equity as previously reported. |

| Recent Accounting Pronouncements |
Recently adopted accounting pronouncements On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, using the modified retrospective transition method with a cumulative adjustment to retained earnings of approximately $0.2 million. ASU 2014-09 is a comprehensive revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. In applying the new guidance, an entity will (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the contract’s performance obligations; and (5) recognize revenue when or as the entity satisfies a performance obligation. For our transportation services businesses, which include truckload, brokerage, intermodal and dedicated services, the adoption of the standard changed the timing of revenue recognition from “at delivery” to “over-time” as the performance obligations on the in-transit services are completed. For our value-added service businesses, the adoption of the standard did not change the timing of revenue recognition. Due to the Company’s short in-transit period for transportation services, the impact did not have a material impact on its consolidated results of operations, financial position or cash flows. The adoption of ASU 2014-09 required an increase in the level of information disclosed in the Notes to Unaudited Consolidated Financial Statements. See Note 3 for additional information. On January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities, using the modified retrospective method. Upon adoption, approximately $3.8 million in accumulated changes in the fair market value of the Company’s equity securities that were presented at December 31, 2017 in accumulated other comprehensive income were reclassified to retained earnings. ASU 2016-01 requires, among other things, equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. On January 1, 2018, the Company prospectively adopted ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, to clarify the definition of a business to assist entities when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The impact of the adoption did not have an impact on its results of operations, financial position or cash flows.
Recent accounting pronouncements not currently effective In February 2016, the FASB issued ASU 2016-02, Leases. The objective of the new standard is to establish principles for lessees and lessors to report information about the amount, timing, and uncertainty of cash flows arising from a lease. The ASU will require a lessee to recognize the assets and liabilities that arise from leases, including operating leases. Under the new requirements, a lessee will recognize in the statement of financial position a liability to make lease payments (the lease liability) and the right-of-use asset representing the right to the underlying asset for the lease term. This guidance will become effective for us January 1, 2019. Although early adoption is permitted, we do not plan to early adopt. In July 2018, the FASB issued additional authoritative guidance providing companies with the option to apply this ASU to new and existing leases within the scope of the guidance as of the beginning of the period of adoption. We plan to elect this transition method of applying the new lease standard and will recognize right-of-use assets, lease liabilities, and any cumulative-effect adjustments to the opening balance of retained earnings as of January 1, 2019. Prior period amounts will not be adjusted and will continue to be reported under the accounting standards in effect for those periods. Upon adoption of the new standard on January 1, 2019, we expect to elect the package of practical expedients provided under the guidance. The practical expedient package applies to leases that commenced prior to adoption of the new standard and permits companies not to reassess whether existing or expired contracts are or contain a lease, the lease classification, and any initial direct costs for any existing leases. We are currently evaluating the effects ASU 2016-02 will have on our consolidated financial statements and related disclosures. As of December 31, 2017, we disclosed approximately $71.8 million in operating lease obligations in Note 9, “Leases” in the Company’s Form 10-K. We will evaluate those contracts as well as other existing arrangements to determine if they qualify for lease accounting under the new standard. Upon adoption, we would expect the amount recognized for the right-of-use assets and lease liabilities to be material to the consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which amends existing guidance for reporting comprehensive income to reflect changes resulting from the Tax Cuts and Jobs Act of 2017. The amendment provides the option to reclassify stranded tax effects within accumulated other comprehensive income (AOCI) to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Act is recorded. New disclosures will be required upon adoption, including the accounting policy for releasing income tax effects from AOCI, whether reclassification of stranded income tax effects is elected, and information about other income tax effect reclassifications. The amendment will become effective for us on January 1, 2019. Although early adoption is permitted, we do not plan to early adopt. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures.
In March 2018, the FASB issued ASU 2018-05, Income Taxes, to clarify the accounting implications of Staff Accounting Bulletin No. 118 ("SAB 118"). SAB 118 provides a measurement period that should not extend beyond one year from December 22, 2017, the date of the enactment of the Tax Cuts and Jobs Act, to complete the accounting under Accounting Standards Codification ("ASC") 740, Income Taxes. As of September 29, 2018, we have not adjusted the provisional estimate recorded at December 31, 2017. We expect to complete our analysis within the measurement period in accordance with SAB 118. |

| Revenue Recognition |
The Company broadly groups its services into the following categories: truckload services, brokerage services, intermodal services, dedicated services and value-added services. Truckload services include dry van, flatbed, heavy-haul and refrigerated operations. We transport a wide variety of general commodities, including automotive parts, machinery, building materials, paper, food, consumer goods, furniture, steel and other metals on behalf of customers in various industries. To complement our available capacity, we provide customers freight brokerage services by utilizing third-party transportation providers to move freight. Brokerage services also include full service domestic and international freight forwarding, and customs brokerage. Intermodal services include rail-truck, steamship-truck and support services. Our intermodal support services are primarily short-to-medium distance delivery of rail and steamship containers between the railhead or port and the customer and drayage services.
Dedicated services are primarily provided in support of automotive and retail customers using specialized van equipment. Dedicated services also include our final mile and ground expedited services. Our dedicated services are primarily short run or round-trip moves within a defined geographic area. Value-added services, which are typically dedicated to individual customer requirements, include material handling, consolidation, sequencing, sub-assembly, cross-dock services, kitting, repacking, warehousing and returnable container management. Value-added revenues are substantially driven by the level of demand for outsourced logistics services. Major factors that affect value-added service revenue includes changes in manufacturing supply chain requirements and production levels in specific industries, particularly the North American automotive and Class-8 heavy-truck industries. Revenue is recognized as control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration the Company expects to receive in exchange for its services. Our transportation services businesses include truckload, brokerage, intermodal and dedicated services. The adoption of ASU 2014-09 changed the timing of revenue recognition for transportation services from at delivery to over-time as the performance obligations on the in-transit services are completed. Transportation services are short-term in nature; agreements governing their provision generally have a term of less than one year. They do not contain significant financing components. In accordance with ASU 2014-09, the Company recognizes revenue over the period transportation services are provided to the customer, including service performed as of the end of the reporting period for loads currently in-transit, in order to recognize the value that is transferred to a customer over the course of the transportation service. We determine revenue in-transit using the input method, under which revenue is recognized based on the duration of time that has lapsed from the departure date (start of transportation services) to the arrival date (completion of transportation services). Measurement of revenue in-transit requires the application of significant judgment. We calculate the estimated percentage of an order’s transit time that is complete at period end, and we apply that percentage of completion to the order’s estimated revenue.
The following table provides information related to contract balances associated with our contracts with customers (in thousands):
We generally receive payment for performance obligations within 45 days of completion of transportation services and 65 days for completion of value-added services. Contract assets in the table above generally relate to revenue in-transit at the end of the reporting period. Practical expedients The Company elected to use the following practical expedients that are available under ASC 606: (i) to apply the new revenue standard to a portfolio of contracts (or performance obligations) with similar characteristics, as we reasonably expect that the effects on the financial statements of applying this guidance to the portfolio would not differ materially from applying this guidance to the individual contracts; (ii) to recognize commission expense when incurred, which we consider to be a cost to obtain a contract, because the amortization period is less than one year; and (iii) to recognize revenue in the value-added services portfolio in the amount of consideration to which we have a right to invoice, that corresponds directly with the value to the customer of the service completed to date. The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. (3) Revenue Recognition - continued
In accordance with the new revenue standard requirements, the impact of adoption on our consolidated statement of income and balance sheet was as follows (in thousands):

| Marketable Securities |
The Company accounts for its marketable equity securities in accordance with ASC Topic 321 “Investments- Equity Securities.” ASC Topic 321 requires companies to measure equity investments at fair value, with changes in fair value recognized in net income. The Company’s investments in marketable securities consist of equity securities with readily determinable fair values. The cost of securities sold is based on the specific identification method, and interest and dividends on securities are included in non-operating income (expense).
Marketable equity securities are carried at fair value, with gains and losses in fair market value included in the determination of net income beginning January 1, 2018. The fair value of marketable equity securities is determined based on quoted market prices in active markets, as described in Note 8.
The following table sets forth market value, cost, and unrealized gains on equity securities (in thousands):
Prior to the Company’s adoption of ASU 2016-01 as of January 1, 2018 , unrealized gains and losses in fair market value were presented as a component of Accumulated Other Comprehensive Income in shareholders’ equity; before adoption of this guidance, the Company included in net income only realized gains and losses and declines in value determined to be other-than-temporary on available-for-sale securities.

| Acquisitions |
On August 10, 2018, the Company acquired all of the outstanding shares of Southern Counties Express, Inc. and certain of its affiliates (collectively, “Southern Counties”). Southern Counties provides full-service harbor drayage, transloading, warehousing, and project cargo services in southern California. The total purchase price was $65.7 million. To finance the acquisition, the Company executed an Amended and Restated Revolving Credit, Term Loan and Security Agreement dated August 10, 2018. Approximately $0.5 million of transaction related costs were incurred in the acquisition. On February 1, 2018, the Company acquired all of the outstanding shares of Fore Transportation, Inc. and certain of its affiliates (collectively, “Fore”). Fore provides its customers with intermodal solutions, including local and regional drayage services. One of the acquired companies owns and leases real property and improvements, including a 28-acre terminal that serves as Fore’s corporate headquarters and a container storage facility. The total cash purchase price was $35.1 million. To fund the acquisition, the Company used a combination of cash and loan proceeds under its margin credit facility, revolving credit facility and secured real estate financing. Approximately $0.2 million of transaction related costs were incurred in the acquisition. The Company accounted for the acquisitions in accordance with ASC 805 “Business Combinations.” Assets acquired and liabilities assumed were recorded at their estimated fair value at acquisition, with the remaining unallocated purchase price recorded as goodwill. The goodwill recorded is included in our transportation segment, and is non-deductible for income tax purposes. The preliminary allocation of the purchase price in each transaction is as follows (in thousands):
The intangible assets represent the acquired companies’ customer relationships, trade names, and non-competition agreements. The acquired customer relationships are being amortized over a period of seven years to 15 years, trade names are being amortized over a period of three years, and the non-competition agreements are being amortized over a period of five years. The Company used the discounted cash flow method to estimate the fair value of these acquired intangible assets.
The following unaudited pro forma results of operations present consolidated information of the Company as if Southern Counties and Fore were acquired on January 1, 2017 (in thousands, except per share data):
The unaudited pro forma consolidated results are presented for illustrative purposes and do not purport to represent what the results of operations would actually have been had we acquired Southern Counties and Fore on January 1, 2017. Further, the financial information does not purport to project the future operating results of the Company on a consolidated basis.
For the thirteen weeks ended September 29, 2018, actual revenue and operating income of the acquired companies was $18.8 million and $2.7 million, respectively. For the thirty-nine weeks ended September 29, 2018, actual revenue and operating income was $33.7 million and $4.6 million, respectively. There were no acquisitions during the thirteen weeks or thirty-nine weeks ended September 30, 2017. |

| Fair Value Measurements and Disclosures |
FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date and expanded disclosures with respect to fair value measurements. FASB ASC Topic 820 also establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:
We have segregated all financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the tables below (in thousands):
The valuation techniques used to measure fair value for the items in the tables above are as follows:
Our revolving credit and term loan agreements and our real estate promissory notes consist of variable rate borrowings. We categorize borrowings under these credit agreements as Level 2 in the fair value hierarchy. The carrying value of these borrowings approximate fair value because the applicable interest rates are adjusted frequently based on short-term market rates. For our equipment promissory notes, the fair values are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. We categorize borrowings under this credit agreement as Level 2 in the fair value hierarchy. The carrying value and estimated fair value of these promissory notes at September 29, 2018 is summarized as follows:
We have not elected the fair value option for any of our financial instruments. |

CenTra, Inc., an affiliate of the Company, provides administrative support services to Universal in the ordinary course of business, including legal, human resources, tax, and IT infrastructure and related services. The cost of these services is based on the actual or estimated utilization of the specific service. Universal also purchases other services from affiliates. Following is a schedule of costs incurred and included in operating expenses for services provided by affiliates for the thirteen weeks and thirty-nine weeks ended September 29, 2018 and September 30, 2017 (in thousands):
We pay CenTra the direct variable cost of maintenance, fueling and other operational support costs for services delivered at our affiliate’s trucking terminals that are geographically remote from our own facilities. Such costs are billed when incurred, paid on a routine basis, and reflect actual labor utilization, repair parts costs or quantities of fuel purchased. In connection with our transportation services, we also pay tolls and other fees for international bridge crossings to certain related entities that are under common control with CenTra. A significant number of our operating locations are located in facilities leased from affiliates. At 34 facilities, occupancy is based on either month-to-month or contractual, multi-year lease arrangements which are billed and paid monthly. Leasing properties provided by an affiliate that owns a substantial commercial property portfolio affords us significant operating flexibility; however, we are not limited to such arrangements. We purchase workers’ compensation, property and casualty, cargo, warehousing and other general liability insurance, as well as obtain surety bonds from an insurance company controlled by our majority shareholders. Our employee health care benefits and 401(k) programs are also provided by this affiliate. Other services from affiliates, including contracted transportation services, are delivered to us on a per-transaction-basis or pursuant to separate contractual arrangements provided in the ordinary course of business. At September 29, 2018 and December 31, 2017, amounts due to affiliates were $15.2 million and $12.0 million, respectively. In our Consolidated Balance Sheets, we record our insured claims liability and the related recovery from an affiliate insurance provider in insurance and claims, and other receivables. At September 29, 2018 and December 31, 2017, there were $8.9 million and $10.1 million, respectively, included in each of these accounts for insured claims. We made purchases of used equipment from an affiliate during the thirty-nine weeks ended September 29, 2018 totaling $8,300, and purchased wheels and tires from an affiliate for new trailering equipment totaling $23,000 during the same period. During the thirty-nine weeks ended September 30, 2017, we purchased used equipment from an affiliate totaling $1.8 million, and purchased wheels and tires from an affiliate for new trailering equipment totaling $1.8 million during the same period.
Services provided by Universal to Affiliates We periodically assist our affiliates by providing selected transportation and logistics services in connection with their specific customer contracts or purchase orders. Following is a schedule of services provided to affiliates for the thirteen weeks and thirty-nine weeks ended September 29, 2018 and September 30, 2017 (in thousands):

| Stock Based Compensation |
On April 23, 2014, our Board of Directors adopted the 2014 Amended and Restated Stock Incentive Plan (the “Plan”). The Plan was approved by our shareholders at the 2014 Annual Meeting and became effective as of the date it was adopted by the Board of Directors. The Plan replaced our 2004 Stock Incentive Plan and carried forward the shares of common stock that remained available for issuance under the 2004 Stock Incentive Plan. The grants may be made in the form of stock options, restricted stock bonuses, restricted stock purchase rights, stock appreciation rights, phantom stock units, restricted stock units or unrestricted common stock. Restricted stock awards currently outstanding under the 2004 Stock Incentive Plan will remain outstanding in accordance with the terms of that plan. On February 22, 2017, February 24, 2016, April 29, 2015 and March 5, 2015, the Company granted 10,000, 10,000, 20,000 and 10,000 shares, respectively, of restricted stock to our Chief Executive Officer. The restricted stock grants have fair values of $13.45 per share, $15.55 per share, $22.03 per share, and $25.18 per share, respectively, based on the closing price of the Company’s stock on each grant date. For each award, 25% of the shares vested immediately on the grant dates, and the remaining shares vest in three equal annual installments with the final vesting of the 2017 award to occur on March 5, 2020, in each case subject to continued employment with the company. On December 23, 2015, the Company granted 50,000 shares of restricted stock to certain of its employees, including 10,000 shares to our Chief Financial Officer. The restricted stock grants have a grant date fair value of $14.93 per share, based on the closing price of the Company’s stock, of which 25% vested immediately, and an additional 25% will vest in three equal increments on each December 20 in 2016, 2017 and 2018. A grantee’s vesting of restricted stock awards may be accelerated under certain conditions, including retirement. The following table summarizes the status of the Company’s non-vested shares and related information for the period indicated:
In each of the thirty-nine week periods ended September 29, 2018 and September 30, 2017, the total grant date fair value of vested shares recognized as compensation costs was $0.2 million. As of September 29, 2018, there was approximately $0.3 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements. That cost is expected to be recognized on a straight-line basis over the remaining vesting period. As a result, the Company expects to recognize stock-based compensation expense of $0.1 million during the remainder of 2018, and $0.1 million in each of 2019 and 2020. |

| Earnings Per Share |
Basic earnings per common share amounts are based on the weighted average number of common shares outstanding, excluding outstanding non-vested restricted stock. Diluted earnings per common share include dilutive common stock equivalents determined by the treasury stock method. For the thirteen weeks and thirty-nine weeks ended September 29, 2018, there were 10,499 and 8,446 weighted average non-vested shares of restricted stock, respectively, included in the denominator for the calculation of diluted earnings per share. For the thirteen weeks and thirty-nine weeks ended September 30, 2017, there were 2,841 and 610 weighted average non-vested shares of restricted stock, respectively, included in the denominator for the calculation of diluted earnings per share. In each of the thirteen weeks and thirty-nine weeks ended September 30, 2017, 35,000 shares of non-vested restricted stock were excluded from the calculation of diluted earnings per share because such shares were anti-dilutive. No shares were excluded from the calculation of diluted earnings per share for the thirteen weeks or thirty-nine weeks ended September 29, 2018. |

We report our financial results in two reportable segments, the transportation segment and the logistics segment, based on the nature of the underlying customer commitment and the types of investments required to support these commitments. This presentation reflects the manner in which management evaluates our operating segments, including an evaluation of economic characteristics and applicable aggregation criteria. Operations aggregated in our transportation segment are associated with individual freight shipments coordinated by our agents, company-managed terminals and specialized services operations. In contrast, operations aggregated in our logistics segment deliver value-added services or transportation services to specific customers on a dedicated basis, generally pursuant to contract terms of one year or longer. Other non-reportable operating segments are comprised of the Company’s subsidiaries that provide support services to other subsidiaries and to owner-operators, including shop maintenance and equipment leasing. The following tables summarize information about our reportable segments as of and for the thirteen week and thirty-nine week periods ended September 29, 2018 and September 30, 2017 (in thousands):

| Commitments and Contingencies |
Our principal commitments relate to long-term real estate leases and payment obligations to equipment vendors. On October 16, 2017, a jury in state court in Cook County, Illinois rendered a verdict of $54.2 million against Universal Am-Can, Ltd. (“UACL”) in the matter of Denton v. UACL, et al. The litigation relates to a vehicular accident that occurred on February 8, 2011 on I-65 in Rensselaer, Indiana. The accident involved a tractor-trailer being driven by an independent owner-operator of UACL. The driver was braking on the expressway in order to avoid another vehicle being driven the wrong way on the interstate. The truck attempted to avoid the oncoming vehicle and the plaintiff’s vehicle and, in so doing, struck the plaintiff’s vehicle. As a result of the accident, the plaintiff sustained non-life threatening injuries. In connection with the verdict, the jury determined that UACL was responsible for the liability associated with the accident. The verdict included $19.2 million in compensatory damages and $35.0 million in punitive damages against UACL. The insurance coverage available for reimbursement of UACL’s damages underlying the verdict is limited to $1.0 million. We believe the facts and the law do not support the jury’s findings of liability against UACL. The Company has filed an appeal with the Appellate Court of Illinois First Judicial District to overturn the verdict and the judgment. Enforcement of the judgment has been stayed pending the outcome of the appeal. The Company currently estimates the possible range of financial exposure, net of insurance coverage, to be between $18.2 million and $53.2 million. Based on the Company’s best estimate of the liability at this time, the Company recorded an accrued liability for this matter of $18.2 million. While we cannot predict with any certainty the outcome of this litigation, its ultimate resolution could be significantly different from our estimate and materially affect our financial condition, results of operations and cash flows. The Company was plaintiff in a lawsuit that was filed on June 11, 2015 against, among others, Dalton Logistics, Inc. (“Dalton”) in the United States District Court for the Southern District of Texas. The Company was seeking approximately $1.9 million in damages from a debtor relating to unpaid freight charges. In response to the filing of the complaint, the shareholders of Dalton filed a counterclaim against the Company alleging that the Company, in connection with certain unrelated negotiations with the defendant, breached an alleged agreement to acquire Dalton. The respective claims proceeded to trial and, on July 21, 2017, a jury returned two separate verdicts: one in favor of Universal for $1.9 million, and a second in favor of the defendant for approximately $5.7 million. On October 30, 2017, the court entered a judgment against Universal for the $5.7 million, but ignored the $1.9 million jury award in favor of Universal. The Company believes this ruling was in error and further believes the jury erred in their findings of any damages against Universal. The Company has filed an appeal with the United States Court of Appeals for the Fifth Circuit to overturn the verdict and the judgment. Enforcement of the judgment has been stayed pending the outcome of the appeal. The Company currently estimates the possible range of financial exposure in the matter to be between $0 and $5.7 million. Based on the Company’s best estimate of the liability at this time, the Company has recorded an accrued liability for this matter of $1.8 million. While we cannot predict with any certainty the outcome of this litigation, management does not believe the outcome will have a material adverse effect on our business, financial condition, results of operations or cash flows.
On February 21, 2018, Ford Motor Company (“Ford”) filed suit against two of the Company’s subsidiaries (collectively, the “Subsidiary Defendants”) and two related parties in state court in Oakland County, Michigan. The complaint sought a declaratory judgment that the Subsidiary Defendants and their co-defendants are required to indemnify Ford for $76 million in damages sustained by Ford in a wrongful death lawsuit in Clay County, Missouri. On November 5, 2018, the trial court granted a Motion for Summary Disposition filed by the defendants, and the claims against the Subsidiary Defendants were dismissed with prejudice. In the third quarter of 2018, a tractor-trailer operated by a subsidiary of the Company was involved in a multi-vehicle, multi-fatality accident. Pre-suit mediation is scheduled for the fourth quarter of 2018. The Company currently estimates the possible range of financial exposure, net of insurance coverage, to be between $2 million and $9 million. Based on the Company’s current best estimate of its subsidiary’s ultimate liability, the Company recorded an accrued liability for this matter of $2 million. While we cannot predict with any certainty the outcome of this matter, its ultimate resolution could be significantly different from our estimate and materially affect our financial condition, results of operations and cash flows. The Company is involved in certain other claims and pending litigation arising from the ordinary conduct of business. We also provide accruals for claims within our self-insured retention amounts. Based on the knowledge of the facts, and in certain cases, opinions of outside counsel, in the Company’s opinion the resolution of these claims and pending litigation will not have a material effect on our financial position, results of operations or cash flows. However, if we experience claims that are not covered by our insurance or that exceed our estimated claim reserve, it could increase the volatility of our earnings and have a materially adverse effect on our financial condition, results of operations or cash flows. At September 29, 2018, approximately 27% of our employees in the United States, Canada and Colombia, and 94% of our employees in Mexico are subject to collective bargaining agreements that are renegotiated periodically, none of which are subject to contracts that expire in 2018. |

On October 12, 2018, the Company entered into and closed on a stock purchase agreement to acquire Specialized Rail Service, Inc. (“Specialized Rail Service” or “SRS”) for approximately $12.3 million. Specialized Rail Service offers local and regional intermodal drayage services, as well as transloading, cross-docking, warehousing and distribution, and intermodal facility management. SRS operates a fleet of over 140 tractors and has facilities in Clearfield, Utah and Las Vegas, Nevada. In connection with the acquisition, a subsidiary of the Company purchased a 7-acre terminal in Clearfield, Utah from an affiliate of SRS for approximately $3.0 million. To finance the acquisition, the Company executed a third amendment to its Credit Agreement with Comerica Bank. On October 25, 2018, our Board of Directors declared a quarterly cash dividend of $0.105 per share of common stock, payable to shareholders of record at the close of business on November 5, 2018 and expected to be paid on November 15, 2018. Declaration of future cash dividends is subject to final determination by the Board of Directors each quarter after its review of our financial condition, results of operations, capital requirements, any legal or contractual restrictions on the payment of dividends and other factors the Board of Directors deems relevant. |

Recent Accounting Pronouncements (Policies) |

| Accounting Policies [Abstract] | |||
| Recent Accounting Pronouncements | Recently adopted accounting pronouncements On January 1, 2018, the Company adopted Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, using the modified retrospective transition method with a cumulative adjustment to retained earnings of approximately $0.2 million. ASU 2014-09 is a comprehensive revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. In applying the new guidance, an entity will (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the contract’s performance obligations; and (5) recognize revenue when or as the entity satisfies a performance obligation. For our transportation services businesses, which include truckload, brokerage, intermodal and dedicated services, the adoption of the standard changed the timing of revenue recognition from “at delivery” to “over-time” as the performance obligations on the in-transit services are completed. For our value-added service businesses, the adoption of the standard did not change the timing of revenue recognition. Due to the Company’s short in-transit period for transportation services, the impact did not have a material impact on its consolidated results of operations, financial position or cash flows. The adoption of ASU 2014-09 required an increase in the level of information disclosed in the Notes to Unaudited Consolidated Financial Statements. See Note 3 for additional information. On January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities, using the modified retrospective method. Upon adoption, approximately $3.8 million in accumulated changes in the fair market value of the Company’s equity securities that were presented at December 31, 2017 in accumulated other comprehensive income were reclassified to retained earnings. ASU 2016-01 requires, among other things, equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. On January 1, 2018, the Company prospectively adopted ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, to clarify the definition of a business to assist entities when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The impact of the adoption did not have an impact on its results of operations, financial position or cash flows.
Recent accounting pronouncements not currently effective In February 2016, the FASB issued ASU 2016-02, Leases. The objective of the new standard is to establish principles for lessees and lessors to report information about the amount, timing, and uncertainty of cash flows arising from a lease. The ASU will require a lessee to recognize the assets and liabilities that arise from leases, including operating leases. Under the new requirements, a lessee will recognize in the statement of financial position a liability to make lease payments (the lease liability) and the right-of-use asset representing the right to the underlying asset for the lease term. This guidance will become effective for us January 1, 2019. Although early adoption is permitted, we do not plan to early adopt. In July 2018, the FASB issued additional authoritative guidance providing companies with the option to apply this ASU to new and existing leases within the scope of the guidance as of the beginning of the period of adoption. We plan to elect this transition method of applying the new lease standard and will recognize right-of-use assets, lease liabilities, and any cumulative-effect adjustments to the opening balance of retained earnings as of January 1, 2019. Prior period amounts will not be adjusted and will continue to be reported under the accounting standards in effect for those periods. Upon adoption of the new standard on January 1, 2019, we expect to elect the package of practical expedients provided under the guidance. The practical expedient package applies to leases that commenced prior to adoption of the new standard and permits companies not to reassess whether existing or expired contracts are or contain a lease, the lease classification, and any initial direct costs for any existing leases. We are currently evaluating the effects ASU 2016-02 will have on our consolidated financial statements and related disclosures. As of December 31, 2017, we disclosed approximately $71.8 million in operating lease obligations in Note 9, “Leases” in the Company’s Form 10-K. We will evaluate those contracts as well as other existing arrangements to determine if they qualify for lease accounting under the new standard. Upon adoption, we would expect the amount recognized for the right-of-use assets and lease liabilities to be material to the consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which amends existing guidance for reporting comprehensive income to reflect changes resulting from the Tax Cuts and Jobs Act of 2017. The amendment provides the option to reclassify stranded tax effects within accumulated other comprehensive income (AOCI) to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Act is recorded. New disclosures will be required upon adoption, including the accounting policy for releasing income tax effects from AOCI, whether reclassification of stranded income tax effects is elected, and information about other income tax effect reclassifications. The amendment will become effective for us on January 1, 2019. Although early adoption is permitted, we do not plan to early adopt. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures.
In March 2018, the FASB issued ASU 2018-05, Income Taxes, to clarify the accounting implications of Staff Accounting Bulletin No. 118 ("SAB 118"). SAB 118 provides a measurement period that should not extend beyond one year from December 22, 2017, the date of the enactment of the Tax Cuts and Jobs Act, to complete the accounting under Accounting Standards Codification ("ASC") 740, Income Taxes. As of September 29, 2018, we have not adjusted the provisional estimate recorded at December 31, 2017. We expect to complete our analysis within the measurement period in accordance with SAB 118. |
