Accounting Policies [Abstract]
Basis of Presentation	(1) Basis of Presentation The accompanying unaudited consolidated financial statements of Universal Truckload Services, Inc. and its wholly-owned subsidiaries (“we”, “us”, “our”, “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, 2014 and 2013 and for each of the years in the three-year period ended December 31, 2014 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. Certain immaterial reclassifications have been made to the prior financial statements in order for them to conform to the September 26, 2015 presentation.

Investments Debt And Equity Securities [Abstract]
Marketable Securities	UNIVERSAL TRUCKLOAD SERVICES, INC. Notes to Unaudited Consolidated Financial Statements (2) Marketable Securities At September 26, 2015 and December 31, 2014, marketable securities, all of which are available-for-sale, consist of common and preferred stocks. Marketable securities are carried at fair value, with unrealized gains and losses, net of related income taxes, reported as accumulated other comprehensive income, except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net income and are included in other non-operating income (expense), at which time the average cost basis of these securities are adjusted to fair value. Fair values are based on quoted market prices at the reporting date. Interest and dividends on available-for-sale securities are included in other non-operating income (expense). The cost, gross unrealized holding gains, gross unrealized holding losses, and fair value of available-for-sale securities by type were as follows (in thousands): Cost Gross unrealized holding gains Gross unrealized holding (losses) Fair Value At September 26, 2015 Equity Securities $ 10,883 $ 3,720 $ (1,195 ) $ 13,408 At December 31, 2014 Equity Securities $ 9,779 $ 4,825 $ (295 ) $ 14,309 Included in equity securities at September 26, 2015 are securities with a fair value of $4.3 million with a cumulative loss position of $1.2 million, the impairment of which we consider to be temporary. We consider several factors in our determination as to whether declines in value are judged to be temporary or other-than-temporary, including the severity and duration of the decline, the financial condition and near-term prospects of the specific issuers and the industries in which they operate, and our intent and ability to hold these securities. We may incur future impairment charges if declines in market values continue and/or worsen and impairments are no longer considered temporary. (2) Marketable Securities - continued The fair value and gross unrealized holding losses of our marketable securities that are not deemed to be other-than-temporarily impaired aggregated by type and length of time they have been in a continuous unrealized loss position were as follows (in thousands): Less 12 Months or Greater Total Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses At September 26, 2015 Equity securities $ 4,067 $ 999 $ 270 $ 196 $ 4,337 $ 1,195 At December 31, 2014 Equity securities $ 1,380 $ 197 $ 146 $ 98 $ 1,526 $ 295 Our portfolio of equity securities in a continuous loss position, the impairment of which we consider to be temporary, consists primarily of common stocks in the oil and gas, banking, steel, and transportation industries. The fair value and unrealized losses are distributed in 40 publicly traded companies, with no single industry or company representing a material or concentrated unrealized loss. We have evaluated the near-term prospects of the various industries, as well as the specific issuers within our portfolio, in relation to the severity and duration of the impairments, and based on that evaluation, as well as our ability and intent to hold these investments for a reasonable period of time to allow for a recovery of fair value, we do not consider these investments to be other-than-temporarily impaired at September 26, 2015. We may, from time to time, invest cash in excess of our current needs in marketable securities, much of which is held in equity securities, which are actively traded on public exchanges. It is our philosophy to minimize the risk of capital loss without foregoing the potential for capital appreciation through investing in value-and-income oriented investments. However, holding equity securities subjects us to fluctuations in the market value of our investment portfolio based on current market prices, and a decline in market prices or other unstable market conditions could cause a loss in the value of our marketable securities classified as available-for-sale.

The Second Amendment modifies the Credit Agreement to allow for additional borrowings of $70 million under a new term loan and a $10 million increase in the revolving credit facility. The Credit Agreement, as amended, consists of a $120 million revolving credit facility (which amount may be increased by up to $20 million upon our request and approval of the lenders), a $60 million equipment credit facility, a $50 million term loan, and a $70 million term loan B. Additionally, the Credit Agreement provides for up to $5 million in letters of credit, which letters of credit reduce availability under the revolving credit facility. $120 million Revolving Credit Facility The revolving credit facility is available to refinance existing indebtedness and to finance working capital through August 28, 2017. Two interest rate options are applicable to advances borrowed pursuant to the facility: Eurodollar-based advances and base rate advances. Eurodollar-based advances bear interest at 30, 60 or 90-day LIBOR rates plus an applicable margin, which varies from 1.35% to 2.10% based on our ratio of total debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”), as defined. As an alternative, base rate advances bear interest at a base rate, as defined, plus an applicable margin, which also varies based on our ratio of total debt to EBITDA in a range from 0.35% to 1.10%. The base rate is the greater of the prime rate announced by Comerica Bank, the federal funds effective rate plus 1.0%, or the daily adjusting LIBOR rate plus 1.0%. At September 26, 2015, interest accrued at 2.05% based on 30-day LIBOR. To support daily borrowing and other operating requirements, the revolving credit facility contains a $10.0 million Swing Line sub-facility and a $5.0 million letter of credit sub-facility. On June 3, 2013, we executed an amendment to our Revolving Credit and Term Loan Agreement (the “First Amendment”) which split the availability on the Swing Line between two existing lenders, Comerica Bank and KeyBank. The Swing Line was split to provide for borrowings of up to $7.0 million from Comerica Bank and $3.0 million from KeyBank, so long as the Comerica Bank and KeyBank advances do not exceed $10.0 million in the aggregate. Swing Line borrowings incur interest at either the base rate plus the applicable margin or, alternatively, at a quoted rate offered by the applicable Swing Line lender in its sole discretion. At September 26, 2015, we did not have any amounts outstanding under the Swing Line, and there were no letters of credit issued against the revolving credit facility. Interest on the unpaid balance of all revolving credit facility and swing line base rate advances is payable quarterly in arrears commencing on October 1, 2012, and on the first day of each October, January, April and July thereafter. Interest on the unpaid balance of each Eurodollar-based advance of the revolving credit facility is payable on the last day of the applicable Eurodollar interest period. Interest on the unpaid balance of each quoted rate based advance of the swing line is payable on the last day of the applicable quoted rate interest period. (4) Debt - continued The revolving credit facility is subject to a facility fee, which is payable quarterly in arrears, of either 0.25% or 0.50%, depending on our ratio of total debt to EBITDA. Other than in connection with Eurodollar-based advances or quoted rate advances that are paid off and terminated prior to an applicable interest period, there are no premiums or penalties resulting from prepayment. Borrowings outstanding at any time under the revolving credit facility are limited to the value of eligible accounts receivable of our principal operating subsidiaries, pursuant to a monthly borrowing base certificate. At September 26, 2015, our $80.5 million revolver advance was secured by, among other assets, net eligible accounts receivable totaling $138.4 million, of which, $114.6 million were available for borrowing against pursuant to the agreement. $60 million Equipment Credit Facility Through August 28, 2015, the equipment credit facility was used to refinance existing indebtedness and to finance capital expenditures including in connection with acquisitions. At September 26, 2015, outstanding borrowings under the equipment credit facility were $49.0 million. Such borrowings are being repaid in quarterly installments equal to 1/28 th The two interest rate options that apply to revolving credit facility advances also apply to equipment credit facility advances. Eurodollar-based advances bear interest at 30, 60 or 90-day LIBOR rates plus an applicable margin, which varies from 1.60% to 2.60% based on our ratio of total debt to EBITDA. Base rate advances bear interest at a base rate, as defined, plus an applicable margin, which also varies based on our ratio of total debt to EBITDA in a range from 0.60% to 1.60%. The equipment credit facility is subject to an unused fee, which is payable quarterly in arrears, of 0.50%. At September 26, 2015, interest accrued at 2.55% based on 30-day LIBOR. Interest on the unpaid balance of all equipment credit facility base rate advances is payable quarterly in arrears commencing on October 1, 2012, and on the first day of each October, January, April and July thereafter. Interest on the unpaid balance of each Eurodollar-based advance of the equipment credit facility is payable on the last day of the applicable Eurodollar interest period. $50 million Term Loan Proceeds of the term loan were advanced on October 1, 2012 and used to refinance existing indebtedness of LINC. The outstanding principal balance is due on August 28, 2017, to the extent not already reduced by mandatory or optional prepayments. The applicable interest rate on the effective date of the term loan indebtedness was the base rate. Base rate advances bear interest at a defined base rate plus an applicable margin which varies from 1.50% to 2.25%, based on our ratio of total debt to EBITDA. Thereafter, we may convert base rate advances to Eurodollar-based advances, which bear interest at 30, 60 or 90-day LIBOR rates plus an applicable margin which varies from 2.50% to 3.25%, based on our ratio of total debt to EBITDA. At September 26, 2015, interest accrued at 3.20% based on 30-day LIBOR. Interest on the unpaid principal of all term loan base rate advances is payable quarterly in arrears commencing on October 1, 2012, and on the first day of each October, January, April and July thereafter. Interest on the unpaid principal of each Eurodollar-based advance of the term loan is payable on the last day of the applicable Eurodollar interest period. $70 million Term Loan B Proceeds of the term loan were advanced on December 19, 2013 and used to finance the acquisition of Westport. The outstanding principal balance is due on August 28, 2017, to the extent not already reduced by mandatory or optional prepayments. The applicable interest rate on the effective date of the term loan indebtedness was the base rate. Base rate advances bear interest at a defined base rate plus an applicable margin which varies from 1.50% to 2.25%, based on our ratio of total debt to EBITDA. Thereafter, we may convert base rate advances to Eurodollar-based advances, which bear interest at 30, 60 or 90-day LIBOR rates plus an applicable margin which varies from 2.50% to 3.25%, based on our ratio of total debt to EBITDA. At September 26, 2015, interest accrued at 3.20% based on 30-day LIBOR. Interest on the unpaid principal of all term loan base rate advances is payable quarterly in arrears commencing on January 1, 2014, and on the first day of each January, April, July and October thereafter. Interest on the unpaid principal of each Eurodollar-based advance of the term loan is payable on the last day of the applicable Eurodollar interest period. (4) Debt - continued The Credit Agreement requires us to repay the borrowings made under the term loan facilities and the equipment credit facility as follows: 50% (which percentage shall be reduced to 0% subject to the Company attaining a certain leverage ratio) of our annual excess cash flow, as defined; 100% of net cash proceeds of certain asset sales; and 100% of certain insurance and condemnation proceeds. There were no mandatory prepayments of the term loans due as of September 26, 2015. We may voluntarily repay outstanding loans under each of the facilities at any time, subject to certain customary “breakage” costs with respect to LIBOR-based borrowings. In addition, we may elect to permanently terminate or reduce all or a portion of the revolving credit facility. All obligations under the Credit Agreement are unconditionally guaranteed by the Company’s material U.S. subsidiaries and the obligations of the Company and such subsidiaries under the Credit Agreement and such guarantees are secured by, subject to certain exceptions, substantially all of their assets. The Credit Agreement also may, in certain circumstances, limit our ability to pay dividends or distributions. The Credit Agreement includes annual, quarterly and ad hoc financial reporting requirements and financial covenants requiring us to maintain maximum leverage ratios and a minimum fixed charge coverage ratio, as well as customary affirmative and negative covenants and events of default. Specifically, we may not exceed a maximum senior debt to EBITDA ratio, as defined, of 2.5:1 and a maximum total debt to EBITDA ratio, as defined, of 3.0:1. We must also maintain a fixed charge coverage ratio, as defined, of not less than 1.25:1. On June 9, 2015, we entered into a third amendment to exclude purchases of up to $35 million of the Company’s common stock in a modified “Dutch auction” tender offer from the calculation of the Company’s fixed charge coverage ratio, as defined in the Credit Agreement. As of September 26, 2015, we were in compliance with our debt covenants. UBS Secured Borrowing Facility We also maintain a secured borrowing facility at UBS Financial Services, Inc., or UBS, using our marketable securities as collateral for the short-term line of credit. The line of credit bears an interest rate equal to LIBOR plus 1.10% (effective rate of 1.29% at September 26, 2015), and interest is adjusted and billed monthly. No principal payments are due on the borrowing; however, the line of credit is callable at any time. The amount available under the line of credit is based on a percentage of the market value of the underlying securities. If the equity value in the account falls below the minimum requirement, we must restore the equity value, or UBS may call the line of credit. As of September 26, 2015 and December 31, 2014, there were no amounts outstanding under the line of credit, and the maximum available borrowings were $7.5 million and $6.9 million, respectively.

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: · Level 1 — Quoted prices in active markets for identical assets or liabilities. · Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. · Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs. (5) Fair Value Measurements and Disclosures – continued We have segregated all financial assets 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): September 26, 2015 Level 1 Level 2 Level 3 Fair Value Measurement Assets Cash equivalents $ 574 $ — $ — $ 574 Marketable securities 13,408 — — 13,408 Total Assets $ 13,982 $ — $ — $ 13,982 December 31, 2014 Level 1 Level 2 Level 3 Fair Value Measurement Assets Cash equivalents $ 21 $ — $ — $ 21 Marketable securities 14,309 — — 14,309 Total Assets $ 14,330 $ — $ — $ 14,330 The valuation techniques used to measure fair value for the items in the tables above are as follows: · Cash equivalents – This category consists of money market funds which are listed as Level 1 assets and measured at fair value based on quoted prices for identical instruments in active markets. · Marketable securities – Marketable securities represent equity securities, which consist of common and preferred stocks, and are listed as Level 1 assets. Fair value was measured based on quoted prices for these securities in active markets. Our senior debt and line of credit consists of variable rate borrowings. We categorize borrowings under the credit agreement and line of credit as Level 2 in the fair value hierarchy.

Related Party Transactions [Abstract]
Transactions with Affiliates	(6) Transactions with Affiliates Through December 31, 2004, we were a wholly-owned subsidiary of CenTra, Inc. On December 31, 2004, CenTra distributed all of our common stock to the shareholders of CenTra. Subsequent to our initial public offering in 2005, our majority shareholders retained and continue to hold a controlling interest in us. CenTra and affiliates of CenTra provide administrative support services to us, including legal, human resources, and tax services. The cost of these services is based on the actual or estimated utilization of the specific service. Management believes these charges are reasonable. However, the costs of these services charged to us are not necessarily indicative of the costs that would have been incurred if we had internally performed or acquired these services as a separate unaffiliated entity. (6) Transactions with Affiliates – continued In addition to the administrative support services described above, we purchase other services from affiliates. Following is a schedule of cost incurred for services provided by affiliates for the thirteen weeks and thirty-nine weeks ended September 26, 2015 and September 27, 2014 (in thousands): Thirteen weeks ended Thirty-nine weeks ended September 26, 2015 September 27, 2014 September 26, 2015 September 27, 2014 Administrative support services $ 1,026 $ 770 $ 2,749 $ 1,728 Truck fueling and maintenance 867 436 1,247 1,042 Real estate rent and related costs 3,149 2,578 9,578 7,852 Insurance and employee benefit plans 13,374 8,695 37,358 27,717 Contracted transportation services 218 494 686 705 Total $ 18,634 $ 12,973 $ 51,618 $ 39,044 In connection with our transportation services, we also routinely cross the Ambassador Bridge between Detroit, Michigan and Windsor Ontario, and we pay tolls and other fees to certain related entities which are under common control with CenTra. CenTra also charges us for the direct variable cost of various maintenance, fueling and other operational support costs for services delivered at their trucking terminals that are geographically remote from our own facilities. Such activities are billed when incurred, paid on a routine basis, and reflect actual labor utilization, repair parts costs or quantities of fuel purchased. A significant number of our transportation and logistics service operations are located at facilities leased from affiliates. At 43 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. In July 2015, we entered into a lease agreement with Cedar Investments LLC, an affiliate, to provide us a logistics facility of up to 500,000 sq. ft. located on 33 acres in close proximity to a major customer in Detroit, Michigan. The term of the lease is 124 months at a rate of approximately $256,500 per month once the new facility is made available for occupancy, which is expected to occur prior to the end of 2015. We purchase workers’ compensation, property and casualty, cargo, warehousing and other general liability insurance 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 leased real estate, insurance and employee benefit plans, and 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 26, 2015 and December 31, 2014, amounts due to affiliates were $5.0 million and $2.9 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 26, 2015 and December 31, 2014, there were $13.7 million and $10.7 million, respectively, included in each of these accounts for insured claims. We did not purchase any tractors or trailers from affiliates during the thirteen weeks or thirty-nine weeks ended September 26, 2015. We did however purchase used snow removal equipment from an affiliate during the thirty-nine weeks ended September 26, 2015, for $18,000. For the thirty-nine weeks ended September 27, 2014, we purchased 10 used tractors and one used trailer from an affiliate totaling approximately $0.8 million. We have retained the law firm of Sullivan Hincks & Conway to provide us legal services. Daniel C. Sullivan, a member of our Board, is a partner at Sullivan Hincks & Conway. Not included in the table above are amounts paid for legal services during the thirteen and thirty-nine weeks ended September 26, 2015 of $500 and $1,500, respectively. Also not included in the table above are amounts paid for legal services during the thirteen and thirty-nine weeks ended September 27, 2014 of $46,000 and $71,000, respectively. We also exercised our right of first refusal to acquire 25,000 shares of restricted stock from a director, H.E. “Scott” Wolfe, for $622,500 based on the closing market price on March 5, 2015, the effective date of the transaction. Effective August 19, 2015, we exercised our right of first refusal to acquire 2,500 shares of restricted stock from our CEO, Jeff Rogers, for $50,825 based on the closing market price on the effective date of the transaction. (6) Transactions with Affiliates – continued Services provided by Universal to Affiliates We may assist our affiliates with 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 26, 2015 and September 27, 2014 (in thousands): Thirteen weeks ended Thirty-nine weeks ended September 26, 2015 September 27, 2014 September 26, 2015 September 27, 2014 Transportation and intermodal services $ 10 $ 5 $ 191 $ 293 Truck fueling and maintenance — 1 — 87 Administrative and customer support services — 66 — 71 Total $ 10 $ 72 $ 191 $ 451 At September 26, 2015 and December 31, 2014, amounts due from affiliates were $1.9 million and $1.6 million, respectively. We did not sell any equipment to affiliates during the thirteen or thirty-nine weeks ended September 26, 2015. During the thirteen weeks ended September 27, 2014, we sold two used trailers to an affiliate for $4,000. The trailers were fully depreciated, and therefore, the sale resulted in a gain of approximately $4,000. For the thirty-nine weeks ended September 27, 2014, we sold 41 used trailers to an affiliate for approximately $82,000. The trailers were fully depreciated, and therefore, the sale resulted in a gain of approximately $82,000. In June 2015, our Board of Directors authorized the repurchase of up to 1,000,000 shares of our common stock through a “Dutch auction” tender offer. Subject to certain limitations and legal requirements, we could repurchase up to an additional 2% of our outstanding shares. The tender offer began on the date of the announcement, June 9, 2015, and expired on July 8, 2015. Through this tender offer, the Company’s shareholders had the opportunity to tender some or all of their shares at a price within the range of $21.50 to $23.50 per share. Upon expiration, 1,599,605 shares were purchased through this offer at a final purchase price of $21.50 per share for a total purchase price of approximately $34.4 million, including fees and commission. The tender offer was settled on July 14, 2015, and we used funds borrowed under our existing line of credit and from our available cash and cash equivalents to fund the offering. Immediately following the consummation of the tender offer, we had 28,380,679 shares of common stock outstanding. The total amount of shares purchased in the tender offer included 1,486,060 shares tendered by Mr. Manuel J. Moroun, a member of Universal’s Board of Directors, and a trust controlled by him. Mr. Moroun is the father of Mr. Matthew T. Moroun, the Chairman of the Board of Directors. During the thirty-nine weeks ended September 27, 2014, we incurred approximately $0.5 million of costs related to an underwritten public offering of our common stock. Under the Amended and Restated Registration Rights Agreement, dated as of July 25, 2012 with our majority shareholders, we were responsible to pay for the cost of the offering. After deducting the underwriting discount and offering expenses, we did not have any remaining proceeds from the sale of our common stock.

Stock Based Compensation	(8) Stock Based Compensation On April 23, 2014, our Board of Directors adopted the 2014 Amended and Restated Stock Incentive Plan, or 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 December 20, 2012, the Company granted 178,137 shares of restricted stock to certain of its employees. The restricted stock grants vested 20% on December 20, 2012, and an additional 20% will vest on each anniversary of the grant through December 20, 2016, subject to continued employment with the Company. On March 5, 2015, the Company granted an additional 10,000 shares of restricted stock its Chief Executive Officer. The restricted stock grants vested 25% on March 5, 2015, and an additional 25% will vest on each anniversary of the grant through March 5, 2018, subject to continued employment with the Company. On April 29, 2015, the Company granted an additional 20,000 shares of restricted stock to the Chief Executive Officer. These restricted stock grants vested 25% on April 29, 2015, and an additional 25% will vest in three equal increments on each March 5 in 2016, 2017 and 2018. A grantee’s vesting 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: Shares Weighted Average Date Non-vested at January 1, 2015 16,446 $ 16.42 Granted 30,000 $ 23.08 Vested (7,500 ) $ 23.08 Forfeited — $ — Balance at September 26, 2015 38,946 $ 20.27 As of September 26, 2015, there was approximately $0.8 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of 1.5 years. The total fair value of shares vested during the thirty-nine weeks ended September 26, 2015 was $0.2 million. No shares vested during the thirteen weeks ended September 26, 2015.

Segment Reporting [Abstract]
Segment Reporting	(11) Segment Reporting 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 period ended September 26, 2015 and September 27, 2014 (in thousands): Thirteen weeks ended September 26, 2015 Transportation Logistics Other Total Operating revenues $ 186,927 $ 97,179 $ 108 $ 284,214 Eliminated inter-segment revenues 662 1,841 — 2,503 Income from operations 8,086 10,129 (1,271 ) 16,944 Total assets 233,791 256,110 37,961 527,862 Thirteen weeks ended September 27, 2014 Transportation Logistics Other Total Operating revenues $ 203,944 $ 98,081 $ 103 $ 302,128 Eliminated inter-segment revenues 743 1,696 — 2,439 Income from operations 10,218 13,992 (1,210 ) 23,000 Total assets 239,126 254,779 30,387 524,292 Thirty-nine weeks ended September 26, 2015 Transportation Logistics Other Total Operating revenues $ 542,884 $ 299,591 $ 307 $ 842,782 Eliminated inter-segment revenues 2,184 4,449 — 6,633 Income from operations 23,602 31,627 (298 ) 54,931 Total assets 233,791 256,110 37,961 527,862 (11) Segment Reporting – continued Thirty-nine weeks ended September 27, 2014 Transportation Logistics Other Total Operating revenues $ 574,667 $ 314,049 $ 325 $ 889,041 Eliminated inter-segment revenues 3,981 5,201 — 9,182 Income from operations 25,347 39,754 (3,059 ) 62,042 Total assets 239,126 254,779 30,387 524,292

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	(13) Recent Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which provided new accounting guidance related to revenue recognition. The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle of ASU 2014-09 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the new guidance, an entity will (1) identify the contract(s) 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. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB Accounting Standards Codification. The new guidance was originally effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 for public companies. Early adoption is not permitted. Entities have the option of using either a full retrospective or modified approach to adopt ASU 2014-09. In July 2015, the FASB voted to delay of the effective date of the new standard by one year. As a result of the delay, the revenue recognition standard will be effective for public companies in 2018, with early adoption permitted. We are evaluating the effect, if any, that adopting this new accounting standard will have on our consolidated financial statements and related disclosures. In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest, which is intended to simplify the presentation of debt issuance costs. ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs would not be affected by the amendments in this update. The new guidance is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2015 for public companies. Entities must apply the new guidance on a full retrospective basis and early adoption is permitted for financial statements that have not been previously issued. We are evaluating the effect that adopting this new accounting standard will have on our consolidated financial statements and related disclosures.
