Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	NOTE 1. Description of Business and Summary of Significant Accounting Policies Business: Hub Group, Inc. (“we”, “us” or “our”) provides intermodal transportation services utilizing primarily third party arrangements with railroads. Drayage can be provided by our subsidiary, Hub Group Trucking, Inc., or a third party company. We offer a dedicated fleet of equipment and drivers through Hub Group Dedicated. We also arrange for transportation of freight by truck and perform logistics services. Transportation services are provided through Hub Group and our subsidiary Mode Transportation, LLC. We report two distinct business segments. The first segment is Mode, which includes the Mode business we acquired in 2011. The other segment is Hub, which is all business other than Mode. “Hub Group” includes both segments. Principles of Consolidation: The consolidated financial statements include our accounts and all entities in which we have more than a 50% equity ownership or otherwise exercise unilateral control. All significant intercompany balances and transactions have been eliminated. Cash and Cash Equivalents: We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less. As of December 31, 2017 and 2016, our cash and temporary investments were with high quality financial institutions in DDAs (Demand Deposit Accounts) and Savings Accounts. Accounts Receivable and Allowance for Uncollectible Accounts: In the normal course of business, we extend credit to customers after a review of each customer’s credit history. An allowance for uncollectible trade accounts has been established through an analysis of the accounts receivable aging, an assessment of collectability based on historical trends, including receivable adjustments charged through revenue for items such as disputes, and an evaluation based on current economic conditions. To be more specific, we reserve a portion of every account balance that has aged over one year, a portion of receivables for customers in bankruptcy and certain account balances specifically identified as uncollectible. On an annual basis, we perform a hindsight analysis on Hub and Mode separately to determine each segment’s experience in collecting account balances over one year old and account balances in bankruptcy. We then use this hindsight analysis to establish our reserves for receivables over one year and in bankruptcy. In establishing a reserve for certain account balances specifically identified as uncollectible, we consider the aging of the customer receivables, the specific details as to why the receivable has not been paid, the customer’s current and projected financial results, the customer’s ability to meet and sustain its financial commitments, the positive or negative effects of the current and projected industry outlook and the general economic conditions. The allowance for uncollectible accounts is reported on the balance sheet in net accounts receivable. Our reserve for uncollectible accounts was approximately $8.5 million and $5.4 million as of December 31, 2017 and 2016, respectively. Receivables are written off once collection efforts have been exhausted. Recoveries of receivables previously charged off are recorded when received. Property and Equipment: Property and equipment are stated at cost. Depreciation of property and equipment is computed using the straight-line method at rates adequate to depreciate the cost of the applicable assets over their expected useful lives: building and improvements, up to 40 years; leasehold improvements, the shorter of useful life or lease term; computer equipment and software, up to 10 years; furniture and equipment, up to 10 years; and transportation equipment up to 15 years. Direct costs related to internally developed software projects are capitalized and amortized over their expected useful life on a straight-line basis not to exceed 10 years. Interest is capitalized on qualifying assets under development for internal use. Maintenance and repairs are charged to operations as incurred and major improvements are capitalized. The cost of assets retired or otherwise disposed of and the accumulated depreciation thereon are removed from the accounts with any gain or loss realized upon sale or disposal charged or credited to operations. We review long-lived assets for impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event that the undiscounted future cash flows resulting from the use of the asset group is less than the carrying amount, an impairment loss equal to the excess of the assets carrying amount over its fair value, less cost to dispose, is recorded. Goodwill and Other Intangibles: Goodwill represents the excess of purchase price over the fair market value of net assets acquired in connection with our business combinations. Goodwill and intangible assets that have indefinite useful lives are not amortized but are subject to annual impairment tests. We test goodwill for impairment annually in the fourth quarter or when events or changes in circumstances indicate the carrying value of this asset might exceed the current fair value. We test goodwill for impairment at the reporting unit level. We assess qualitative factors such as current company performance and overall economic factors to determine if it is more-likely-than-not that the goodwill might be impaired and whether it is necessary to perform the quantitative goodwill impairment test. In the quantitative goodwill test, a company compares the carrying value of a reporting unit to its fair value. If the carrying value of the reporting unit exceeds the estimated fair value, a second step is performed, which compares the implied fair value of goodwill to the carrying value, to determine the amount of impairment. In 2017 and 2016, we performed the qualitative assessment on both the Hub and Mode reporting units and determined it was not, more-likely-than-not, that goodwill might be impaired. We evaluate the potential impairment of finite-lived acquired intangible assets when impairment indicators exist. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset. Concentration of Credit Risk: Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We place our cash and temporary investments with high quality financial institutions in DDAs (Demand Deposit Accounts) and Savings Accounts. We primarily serve customers located throughout the United States with no significant concentration in any one region. No one customer accounted for more than 10% of revenue in 2017, 2016 or 2015. We review a customer’s credit history before extending credit. In addition, we routinely assess the financial strength of our customers and, as a consequence, believe that our trade accounts receivable risk is limited. Revenue Recognition: Revenue is recognized at the time 1) persuasive evidence of an arrangement exists, 2) services have been rendered, 3) the sales price is fixed and determinable and 4) collectability is reasonably assured. Revenue and related transportation costs are recognized based on relative transit time. Further, in most cases, we report our revenue on a gross basis because we are the primary obligor as we are responsible for providing the service desired by the customer. Our customers view us as responsible for fulfillment including the acceptability of the service. Service requirements may include, for example, on-time delivery, handling freight loss and damage claims, setting up appointments for pick-up and delivery and tracing shipments in transit. We have discretion in setting sales prices and as a result, the amount we earn varies. In addition, we have the discretion to select our vendors from multiple suppliers for the services ordered by our customers. Finally, we have credit risk for our receivables. These three factors, discretion in setting prices, discretion in selecting vendors and credit risk, further support reporting revenue on a gross basis for substantially all of our revenue. Provision for Income Taxes: Deferred income taxes are recognized for the future tax effects of temporary differences between financial and income tax reporting using tax rates in effect for the years in which the differences are expected to reverse. We believe that it is more likely than not that our deferred tax assets will be realized based on future taxable income projections with two exceptions for which we have established valuation allowances. We have established valuation allowances of $0.1 million related to state tax net operating losses and $1.6 million related to state incentive tax credit carryforwards. In the event the probability of realizing the remaining deferred tax assets do not meet the more likely than not threshold in the future, a valuation allowance would be established for the deferred tax assets deemed unrecoverable. Tax liabilities are recorded when, in management’s judgment, a tax position does not meet the more likely than not threshold for recognition as prescribed by the guidance. For tax positions that meet the more likely than not threshold, a tax liability may be recorded depending on management’s assessment of how the tax position will ultimately be settled. We recognize interest expense and penalties related to income tax liabilities in our provision for income taxes. Earnings Per Common Share: Basic earnings per common share are based on the average quarterly weighted average number of Class A and Class B shares of common stock outstanding. Diluted earnings per common share are adjusted for the assumed exercise of dilutive stock options and for restricted stock which are both computed using the treasury stock method. Stock Based Compensation: Share-based compensation includes the restricted stock awards expected to vest based on the grant date fair value. Compensation expense is amortized straight-line over the vesting period and is included in salaries and benefits. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification of related amounts within the statement of cash flows. The new standard became effective beginning with the first quarter of 2017. We adopted ASU 2016-09 in the first quarter of 2017 and the adoption did not have a material impact on our consolidated financial statements. We have applied the reclassification of excess tax benefits prospectively and therefore the prior period has not been adjusted. We presented in both 2016 and 2015 excess tax benefits resulting from the exercise of share-based compensation as financing cash in-flows and as operating cash out-flows in the Consolidated Statements of Cash Flows. New Pronouncements: In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606), which will provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The new standard is effective for annual reporting periods beginning after December 15, 2017. We have been closely monitoring FASB activity related to the new standard. In the first half of 2017, we made significant progress toward completing our evaluation of the potential changes from adopting the new standard on our future financial reporting and disclosures. In the second half of 2017, we finalized our contract reviews and our detailed accounting policy. Based on our evaluation, we adopted the requirements of the new standard on January 1, 2018 and will use the full retrospective transition method. The impact of adopting Topic 606 primarily relates to recording all taxes assessed by a governmental authority that are both, imposed on and concurrent with a specific revenue-producing transaction and collected by Hub Group from a customer on a net basis, which previously were recorded on a gross basis. We expect this election to have approximately a $3.0 million impact on our consolidated financial statements in 2017 and 2016. The impact to our results is restricted to taxes because the analysis of our contracts under the new revenue recognition standard supports the recognition of revenue over time for our contracts, which is consistent with our current revenue recognition model. Revenue on the majority of our contracts will continue to be recognized over time because of the continuous transfer of control to the customer. This continuous transfer of control to the customer is supported by clauses in the contracts that allow the customer to terminate the contract for convenience or by our rights to payment for work performed to date. In addition, the number of our performance obligations under the new standard is not materially different from our contract segments under the existing standard. Lastly, the accounting for the estimate of variable consideration is not materially different compared to our current practice. The new standard clarifies how to account for principal (gross) versus agent (net) in revenue recognition. We have concluded that the adoption of this standard will not have a material impact on our consolidated financial statements. In 2016, the FASB issued new guidance which clarifies the classification of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of contingent consideration arising from a business combination, insurance settlement proceeds, and distributions from certain equity method investees. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. This standard was adopted on January 1, 2018. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business. This ASU clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. This standard was adopted on January 1, 2018 and we are evaluating the effect that this guidance will have on any future acquisitions. In 2016, the FASB issued new guidance that requires credit losses on financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, not based on incurred losses. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 is permitted. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases, which requires lessees to recognize a right-to-use asset and a lease obligation for all leases. Lessees are permitted to make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less. The new standard will become effective beginning with the first quarter of 2019. Early adoption of the standard is permitted. We plan to adopt this standard January 1, 2019, as required. We are currently evaluating the impact the adoption of this accounting guidance will have on the consolidated financial statements. Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Significant estimates include the allowance for doubtful accounts, exposure under our insurance policies and useful lives of assets. Actual results could differ from those estimates.

Acquisition

NOTE 4.

Acquisition

Hub Group Trucking (HGT), a wholly owned subsidiary of Hub Group, Inc., acquired all of the outstanding equity interests of Estenson Logistics, LLC (“Estenson”) on July 1, 2017 (the “Estenson Acquisition”). Estenson is now our wholly owned subsidiary, operating under the name Hub Group Dedicated (“HGD”). As a result of the Estenson Acquisition, HGT acquired substantially all of the assets of Estenson, which include tractors and trailers, as well as assumed certain liabilities, including equipment debt. HGD is included in the Hub segment.

HGD has an operating fleet of approximately 1,100 tractors and 4,700 trailers. Dedicated services have been requested by our customers and we believe HGD is an excellent service offering that we can provide to our customers.

The base purchase price for Estenson was approximately $284.7 million, including contingent consideration related to an earn-out provision included in the Purchase Agreement, which will not exceed $6.0 million and is based on Estenson’s EBITDA results through June 30, 2019. In accordance with the agreement, the base purchase price was adjusted by the assumed debt to arrive at the final consideration of $172.0 million. To facilitate the acquisition, we assumed $112.7 million of Estenson debt and paid $165.9 million in cash, including $55.0 million of cash, which was borrowed under our new credit agreement (See Note 10).

The following table summarizes the total purchase price allocated to the net assets acquired (in thousands):

Cash paid	$	165,945
Consideration payable		1,366
Contingent consideration, fair value		4,703
Total consideration		172,014
Equipment debt assumed		112,677
Total base purchase price	$	284,691

Pending finalization of the fair market value of assets acquired and liabilities assumed, the measurement period remains open. The following table summarizes the preliminary allocation of the total consideration to the assets acquired and liabilities assumed as of the date of the acquisition (in thousands):

	July 1, 2017
Cash and cash equivalents	$	12
Accounts receivable trade		26,830
Accounts receivable other		165
Prepaid expenses and other current assets		1,500
Property and equipment		128,477
Other intangibles		66,400
Goodwill		86,504

Total assets acquired	$	309,952

Accounts payable trade	$	4,542
Accrued payroll		5,661
Accrued other		15,058
Equipment debt		112,677
Total liabilities assumed	$	137,938

Total consideration	$	172,014

The Estenson acquisition was accounted for as a purchase business combination in accordance with ASC 805 “Business Combinations.” Assets acquired and liabilities assumed were recorded in the accompanying consolidated balance sheet at their estimated fair values as of July 1, 2017 with the remaining unallocated purchase price recorded as goodwill. The goodwill recognized in the Estenson acquisition was primarily attributable to potential expansion and future development of the acquired business. The fair value assigned to the customer relationships identifiable intangible was determined using an income approach based on management’s estimates and assumptions. The fair value assigned to the property and equipment was determined based on a market approach. A probability weighted expected return model was used to estimate the value of the contingent consideration. Equipment debt was valued using a discounted cash flow analysis whereby future contractual principal repayments and interest payments for each instrument were discounted to the purchase date at a risk-adjusted discount rate.

We incurred approximately $1.6 million of acquisition costs associated with this transaction prior to the closing date that are reflected in general and administrative expense in the accompanying Consolidated Statements of Income for the twelve months ended December 31, 2017.

The total amount of tax deductible goodwill as of December 31, 2017 is $80.6 million, which will be amortized over 15 years. As of December 31, 2017, there are $5.9 million of assumed liabilities which, as they are paid, will result in additional tax deductible goodwill which can be amortized over the remainder of the 15 year period which started in July 2017.

The components of “Other intangibles” listed in the above table as of the acquisition date are preliminarily estimated as follows (in thousands):

			Accumulated		Balance at		Estimated Useful
	Amount		Amortization		December 31, 2017		Life
Customer relationships	$	66,000	$	2,200	$	63,800	15 years
Trade name	$	400	$	400	$	0	3 months

The above intangible assets are amortized using the straight-line method. Amortization expense related to this acquisition for the twelve month period ended December 31, 2017 was $2.6 million. The intangible assets have a weighted average useful life of approximately 15 years. Amortization expense related to HGD for the next five years is as follows (in thousands):

2018			$4,400
2019			4,400
2020			4,400
2021			4,400
2022			4,400

The following unaudited pro forma consolidated results of operations for 2017 and 2016 assume that the acquisition of Estenson was completed as of January 1, 2016 (in thousands, except for per share amounts):

Segment Reporting [Abstract]

Business Segments

NOTE 5. Business Segments

We report two distinct business segments. The first segment is Mode, which includes the Mode LLC business we acquired on April 1, 2011. The second segment is Hub, which is all business other than Mode.

Hub offers comprehensive intermodal, truck brokerage, logistics and dedicated services. Our employees operate the freight through a network of operating centers located in the United States, Canada and Mexico. Each operating center is strategically located in a market with a significant concentration of shipping customers and one or more railheads. Hub has full time employees located throughout the United States, Canada and Mexico.

Mode LLC markets and operates its freight transportation services, consisting of intermodal, truck brokerage and logistics, primarily through agents who enter into contractual arrangements with Mode LLC.

The following is a summary of operating results for our business segments for the years ended December 31, 2017, 2016 and 2015 (in thousands):

Goodwill and Other Intangible Assets

NOTE 6. Goodwill and Other Intangible Assets

In accordance with the FASB issued guidance in the Intangibles-Goodwill and Other Topic of the Codification, we completed the required annual impairment tests. We performed a qualitative assessment on both the Hub segment goodwill and the Mode segment goodwill and determined it was not, more-likely-than-not, that goodwill might be impaired. There were no accumulated impairment losses of goodwill at the beginning of the period.

The following table presents the carrying amount of goodwill (in thousands):

						Hub Group
	Hub			Mode		Total

Income Taxes

NOTE 7. Income Taxes

The Tax Cuts and Jobs Act was enacted on December 22, 2017. The Act reduces the US federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. At December 31, 2017, we have not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. In other cases, we have not been able to make a reasonable estimate and continue to account for those items based on our existing accounting under ASC 740, Income Taxes, and the provisions of the tax laws that were in effect immediately prior to enactment. For the items for which we were able to determine a reasonable estimate, we recognized a tax benefit of $75.2 million, which is included as a component of income tax expense from continuing operations. In all cases, we will continue to make and refine our calculations as additional analysis is completed. In addition, our estimates may also be affected as we gain a more thorough understanding of the tax law.

Due to the complexities involved in accounting for the enactment of the Act, the SEC Staff Accounting Bulletin No. 118 (“SAB No. 118”) allowed the Company to record provisional amounts in earnings for the year ended December 31, 2017. Where reasonable estimates can be made, the provisional accounting should be based on such estimates. When no reasonable estimate can be made, the provisional accounting may be based on the tax law in effect before the Act. The Company is required to complete its tax accounting for the Act within a one year period when it has obtained, prepared, and analyzed the information to complete the income tax accounting.

Deferred tax assets and liabilities: We remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. However, we are still analyzing certain aspects of the Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The tax benefit recorded related to the remeasurement of our deferred tax balance was $75.2 million.

We are subject to income taxation in the U.S., numerous state jurisdictions, Mexico and Canada. Because income tax return formats vary among the states, we file both unitary and separate company state income tax returns. Our state tax net operating losses of $1.4 million expire between December 31, 2018 and December 31, 2037. Our state incentive tax credit carryforwards of $3.4 million expire between December 31, 2019 and December 31, 2022. Management believes it is more likely than not that these deferred tax assets will be realized with the exception of $0.1 million related to state tax net operating losses, and $1.6 million related to state tax incentive credit carryforwards. Valuation allowances totaling $1.7 million have been established for each of these amounts.

As of December 31, 2017 and December 31, 2016, the amount of unrecognized tax benefits was $3.8 million and $1.8 million, respectively. Of these amounts, our income tax provision would decrease $2.8 million and $1.2 million, respectively, if recognized. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

	2017			2016
Gross unrecognized tax benefits - beginning of the year	$	1,832		$	1,139
Gross increases related to prior year tax positions		1,830			394
Gross increases related to current year tax positions		290			488
Lapse of applicable statute of limitations		(125	)		(189	)
Gross unrecognized tax benefits - end of year	$	3,827		$	1,832

We estimate it is reasonably possible that our reserve could either increase or decrease by up to $1.0 million during the next twelve months.

We recognize interest expense and penalties related to income tax liabilities in our provision for income taxes. In our 2017 provision for income taxes, we recognized approximately three thousand dollars of expense for combined income tax interest and income tax penalty.

In 2017, we were selected for examinations by Illinois for our 2014 and 2015 tax years, by Michigan for our 2012 through 2015 tax years, by Minnesota for our 2013 through 2015 tax years and by Massachusetts for our 2013 through 2015 tax years. In addition, examinations that began in 2016 by the IRS for our 2014 year and California for our 2012 and 2013 years continued in 2017. The Minnesota and California examinations are still ongoing. The Massachusetts audit was settled for approximately $10,000, and the Illinois, Michigan and IRS audits closed with no additional tax due.

Fair Value Measurement	12 Months Ended
Fair Value Measurement	Dec. 31, 2017
Fair Value Disclosures [Abstract]
Fair Value Measurement	NOTE 8. Fair Value Measurement The carrying value of cash and cash equivalents, accounts receivable, accounts payable and debt materially approximated fair value as of December 31, 2017 and 2016 due to their short-term nature. We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less. As of December 31, 2017 and 2016, our cash and temporary investments were with high quality financial institutions in (DDAs) Demand Deposit Accounts and Savings Accounts. Restricted investments included $24.2 million and $20.9 million as of December 31, 2017 and 2016, respectively, of mutual funds which are reported at fair value. These investments relate to the nonqualified deferred compensation plan that is described in Note 13. Our assets and liabilities measured at fair value are based on valuation techniques which consider prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. These valuation methods are based on either quoted market prices (Level 1) or inputs, other than quoted prices in active markets, that are observable either directly or indirectly (Level 2). Cash and cash equivalents, accounts receivable and accounts payable are defined as “Level 1,” while long-term debt is defined as “Level 2” of the fair value hierarchy in the Fair Value Measurements and Disclosures Topic of the Codification.

The increase in transportation equipment to $621.0 million in 2017 from $472.6 million in 2016 was due primarily to the purchase of containers and assets related to the acquisition of HGD comprised primarily of trailers and tractors.

The increase in computer software and hardware to $109.3 million in 2017 from $91.3 million in 2016 was related to our transportation management system.

Included in the transportation equipment is a capital lease obligation entered into for $26.4 million in 2011. The balances as of December 31, 2017 and 2016, net of accumulated amortization, were $10.0 million and $12.3 million, respectively.

Depreciation and amortization expense related to property and equipment was $58.1 million, $43.4 million and $35.9 million for 2017, 2016 and 2015, respectively, which includes amortization expense associated with a capital lease of $2.2 million for 2017, $2.3 million for 2016 and $2.6 million for 2015.

Long-Term Debt and Financing Arrangements

NOTE 10. Long-Term Debt and Financing Arrangements

On July 1, 2017, we entered into a $350 million unsecured credit agreement (the "Credit Agreement"). The Credit Agreement replaces the Amended and Restated Credit Agreement dated December 12, 2013 (“2013 Credit Agreement”). The Company used the Credit Agreement to finance, in part, the Estenson Acquisition.

Borrowings under the Credit Agreement generally bear interest at a variable rate equal to (i) LIBOR plus a specified margin based upon the Borrowers' total net leverage ratio (as defined in the Credit Agreement) (the "Total Net Leverage Ratio"), or (ii) the base rate (which is the highest of (a) the administrative agent's prime rate, (b) the federal funds rate plus 0.50% or (c) the sum of 1% plus one-month LIBOR) plus a specified margin based upon the Total Net Leverage Ratio. The specified margin for Eurodollar loans varies from 100.0 to 200.0 basis points per annum. The specified margin for base rate loans varies from 0.0 to 100.0 basis points per annum. The Borrowers must also pay (1) a commitment fee ranging from 10.0 to 25.0 basis points per annum (based upon the Total Net Leverage Ratio) on the aggregate unused commitments and (2) a letter of credit fee ranging from 100.0 to 200.0 basis points per annum (based upon the Total Net Leverage Ratio) on the undrawn amount of letters of credit.

The Credit Agreement contains various restrictions and covenants, including negative covenants that limit or restrict dividends, indebtedness of subsidiaries, mergers and fundamental changes, asset sales, acquisitions, liens and encumbrances, transactions with affiliates, changes in fiscal year and other matters customarily restricted in such agreements. The Company must maintain a Total Net Leverage Ratio of (a) total funded debt as of such date, minus up to $50.0 million in unrestricted cash and cash equivalents (each as defined in the Credit Agreement) to (b) consolidated EBITDA (as defined in the credit agreement) of not more than 3.00 to 1.00; provided that as of the close of each of the four fiscal quarters occurring after the consummation of a permitted acquisition (as defined in the Credit Agreement) with an aggregate consideration of $150.0 million or more, such ratio shall not be more than 3.25 to 1.00. The Company must maintain an interest coverage ratio of consolidated EBITDA to consolidated cash interest expense of not less than 3.00 to 1.00.

We have standby letters of credit that expire in 2018. As of December 31, 2017, our letters of credit were $20.1 million.

Our unused and available borrowings under our bank revolving line of credit were $284.9 million as of December 31, 2017. Our unused and available borrowings under the 2013 Credit Agreement were $38.2 million as of December 31, 2016. We were in compliance with our debt covenants as of December 31, 2017.

We have entered into various Equipment Notes (“Notes”) for the purchase of tractors, trailers and containers. The Notes are secured by the underlying equipment financed in the agreements.

In 2011, we entered into a lease agreement for 3,126 chassis for a period of 10 years. We are accounting for this lease as a capital lease. Interest on this capital lease obligation is based on interest rates that approximate currently available interest rates; therefore, indebtedness under this capital lease obligation approximates fair value. We paid interest of $0.5 million, $0.6 million and $0.7 million in 2017, 2016 and 2015, respectively, related to this capital lease.

In February 2018, we entered in a secured equipment note for the purchase of 29 tractors and 36 trailers for $5.0 million. The note calls for 60 monthly payments of $91,986 and has a fixed interest rate of 3.56%.

Many of the real estate leases contain renewal options and escalation clauses which require payments of additional rent to the extent of increases in the related operating costs. We straight-line rental expense in accordance with the FASB guidance in the Leases Topic of the Codification.

We incur rental expense for our leased containers, tractors and trailers that are included in transportation costs and totaled $6.0 million, $3.6 million, and $11.9 million for 2017, 2016 and 2015, respectively.

We incur user charges for use of a fleet of rail owned chassis, chassis under capital lease and dedicated rail owned containers on the Union Pacific and Norfolk Southern railroads which are included in transportation costs.

Stock-Based Compensation Plans

NOTE 12. Stock-Based Compensation Plans

The 2017 Long-Term Incentive Plan (the “2017 Incentive Plan”) was approved by the Board of Directors and subsequently approved by the Company’s stockholders at the 2017 annual meeting. The 2017 Incentive Plan authorizes a broad range of awards including stock options, stock appreciation rights, restricted stock and restricted stock units, performance shares or units, other stock-based awards, and cash incentive awards to all employees (including the Company’s executive officers), directors, consultants, independent contractors or agents of us or a related company. The 2017 Incentive Plan is effective as of March 15, 2017.

The 2017 Incentive Plan replaced the Company’s 2002 Long-Term Incentive Plan, as amended (the “2002 Incentive Plan”). Under the 2002 Incentive Plan, stock options, stock appreciation rights, restricted stock, restricted stock units and performance units could be granted for the purpose of attracting and motivating our key employees and non-employee directors. As of the effective date of the 2017 Incentive Plan, there were a total of 707,273 shares of our Class A common stock (“Common Stock”) under the 2002 Incentive Plan available to be issued upon exercise or settlement of outstanding awards.

As of December 31, 2017, 1,948,363 shares were available for future grant under the 2017 Incentive Plan.

We have not granted any stock options since 2003 and have no stock options outstanding. Restricted stock vests over a three to five year period for all recipients other than the Company’s non-employee Directors. The non-employee Directors restricted stock vests over a one to three year period.

Share-based compensation expense for 2017, 2016 and 2015 was $9.9 million, $8.5 million and $7.8 million or $6.5 million, $5.2 million and $5.0 million, net of taxes, respectively.

At our discretion, we partially match qualified contributions made by employees to the plan. We incurred expense of $3.0 million related to this plan in 2017, $2.4 million in 2016 and $1.9 million in 2015. In January 2005, we established the Hub Group, Inc. Nonqualified Deferred Compensation Plan (the “Plan”) to provide added incentive for the retention of certain key employees. Under the Plan, which was amended in 2008, participants can elect to defer certain compensation. Accounts will grow on a tax-deferred basis to the participant. Restricted investments included in the Consolidated Balance Sheets represent the fair value of the mutual funds and other security investments related to the Plan as of December 31, 2017 and 2016. Both realized and unrealized gains and losses are included in income and expense and offset the change in the deferred compensation liability. We provide a 50% match on the first 6% of employee compensation deferred under the Plan, with a maximum match equivalent to 3% of base salary. In addition, we have a legacy deferred compensation plan. There are no new contributions being made into this legacy plan. We incurred expense of $0.3 million per year related to the employer match for these plans in 2017, 2016 and 2015. The liabilities related to these plans as of December 31, 2017 and 2016 were $24.4 million and $21.1 million, respectively.

Commitments And Contingencies Disclosure [Abstract]
Legal Matters	NOTE 14. Legal Matters Robles On January 25, 2013, a complaint was filed in the U.S. District Court for the Eastern District of California (Sacramento Division) by Salvador Robles against our subsidiary Hub Group Trucking, Inc (“HGT”). The action is brought on behalf of a class comprised of present and former California-based truck drivers for HGT who were classified as independent contractors, from January 2009 to August 2014. It alleges HGT has misclassified such drivers as independent contractors and that such drivers were employees. It asserts various violations of the California Labor Code and claims that HGT has engaged in unfair competition practices. The complaint seeks, among other things, declaratory and injunctive relief, monetary damages and attorney’s fees. In May 2013, the complaint was amended to add similar claims based on Mr. Robles’ status as an employed company driver. These additional claims are only on behalf of Mr. Robles and not a putative class. The Company believes that the California independent contractor truck drivers were properly classified as independent contractors at all times. Nevertheless, because lawsuits are expensive, time-consuming and could interrupt our business operations, HGT decided to make settlement offers to individual drivers with respect to the claims alleged in this lawsuit, without admitting liability. As of December 31, 2017, 96% of the California drivers have accepted the settlement offers. In late 2014, HGT decided to convert its model from independent contractors to employee drivers in California (the “Conversion”). In early 2016, HGT closed its operations in Southern California. On April 3, 2015, the Robles case was transferred to the U.S. District Court for the Western District of Tennessee (Western Division) in Memphis. On May 15, 2015, Plaintiffs filed a Second Amended Complaint (“SAC”) which names 334 current and former HGT drivers as “interested putative class members.” In addition to reasserting their existing claims, the SAC includes claims post-Conversion, added two Plaintiffs (who had signed the settlement agreement above) and seeks a judicial declaration that the settlement agreements are unenforceable. On June 8, 2015, HGT filed a motion to dismiss the SAC and on July 19, 2016, HGT’s motion to dismiss was granted in part, and denied in part, by the District Court. The motion to dismiss was granted for the claims of all purported class members who have signed settlement agreements and for the plaintiffs’ claims based on quantum merit. It was denied with respect to federal preemption and choice of law. On August 11, 2016, Plaintiffs filed a motion to clarify whether the Court’s dismissal of the claims of all purported class members who signed settlement agreements was with or without prejudice and, if the dismissal was with prejudice, Plaintiffs moved the Court to revise and reconsider the order. Plaintiffs’ motion for clarification/reconsideration has been fully briefed and the parties are awaiting a decision by the Court. Adame On August 5, 2015, the Plaintiffs’ law firm in the Robles case filed a lawsuit in state court in San Bernardino County, California on behalf of 63 named Plaintiffs against HGT and five Hub and HGT employees. The lawsuit alleges claims similar to those being made in Robles and seeks penalties under California’s Private Attorneys General Act (“PAGA”). Of the 63 named Plaintiffs, at least 58 signed settlement agreements. On October 29, 2015, Defendants filed a notice of removal to move the case from state court in San Bernardino to federal court in the Central District of California. On November 19, 2015, Plaintiffs filed a motion to remand the case back to state court, claiming that the federal court lacks jurisdiction over the case because there is not complete diversity of citizenship between the parties and the amount in controversy threshold is not satisfied. The court granted Plaintiffs’ motion to remand to the state court in San Bernardino County on April 7, 2016. On July 11, 2016, Defendants filed dismissal papers in state court, asking the court to dismiss Plaintiffs’ suit for various reasons, including that the agreement between HGT and its former California owner operators requires that this action be brought in Memphis, Tennessee, or stay the action pending the outcome of Robles. Defendants also asked the court to dismiss the individual defendants because PAGA’s language does not allow for individual liability. During a hearing on October 5, 2016, the judge issued an oral tentative ruling stating that the choice of forum provision was unenforceable. On February 17, 2017, with the stipulation of the parties, the Court entered an order dismissing, without prejudice, all of the individual Defendants and accepting the parties’ agreement that jurisdiction and venue are proper in the San Bernardino Superior Court and that Defendants will not seek to remove the case to federal district court. On April 12, 2017, the Court denied Defendant’s motion to dismiss based on insufficiency of the PAGA letter notice. On October 19, 2017, Plaintiffs filed an amended complaint, dismissing the previously named individuals as Defendants. On December 4, 2017, Defendants filed an Answer to Plaintiffs’ First Amended Complaint and a Memorandum of Points and Authorities in Support of their Motion for Judgment on the Pleadings. On January 31, 2018, a hearing was held on the motion to dismiss, and on February 1, 2018, the motion was denied. A trial setting conference is set for April 12, 2018.

We report two distinct business segments. The first segment is Mode, which includes the Mode business we acquired in 2011. The other segment is Hub, which is all business other than Mode. “Hub Group” includes both segments.
Principles of Consolidation	Principles of Consolidation: The consolidated financial statements include our accounts and all entities in which we have more than a 50% equity ownership or otherwise exercise unilateral control. All significant intercompany balances and transactions have been eliminated.
Cash and Cash Equivalents	Cash and Cash Equivalents: We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less. As of December 31, 2017 and 2016, our cash and temporary investments were with high quality financial institutions in DDAs (Demand Deposit Accounts) and Savings Accounts.
Accounts Receivable and Allowance for Uncollectible Accounts	Accounts Receivable and Allowance for Uncollectible Accounts: In the normal course of business, we extend credit to customers after a review of each customer’s credit history. An allowance for uncollectible trade accounts has been established through an analysis of the accounts receivable aging, an assessment of collectability based on historical trends, including receivable adjustments charged through revenue for items such as disputes, and an evaluation based on current economic conditions. To be more specific, we reserve a portion of every account balance that has aged over one year, a portion of receivables for customers in bankruptcy and certain account balances specifically identified as uncollectible. On an annual basis, we perform a hindsight analysis on Hub and Mode separately to determine each segment’s experience in collecting account balances over one year old and account balances in bankruptcy. We then use this hindsight analysis to establish our reserves for receivables over one year and in bankruptcy. In establishing a reserve for certain account balances specifically identified as uncollectible, we consider the aging of the customer receivables, the specific details as to why the receivable has not been paid, the customer’s current and projected financial results, the customer’s ability to meet and sustain its financial commitments, the positive or negative effects of the current and projected industry outlook and the general economic conditions. The allowance for uncollectible accounts is reported on the balance sheet in net accounts receivable. Our reserve for uncollectible accounts was approximately $8.5 million and $5.4 million as of December 31, 2017 and 2016, respectively. Receivables are written off once collection efforts have been exhausted. Recoveries of receivables previously charged off are recorded when received.
Property and Equipment	Property and Equipment: Property and equipment are stated at cost. Depreciation of property and equipment is computed using the straight-line method at rates adequate to depreciate the cost of the applicable assets over their expected useful lives: building and improvements, up to 40 years; leasehold improvements, the shorter of useful life or lease term; computer equipment and software, up to 10 years; furniture and equipment, up to 10 years; and transportation equipment up to 15 years. Direct costs related to internally developed software projects are capitalized and amortized over their expected useful life on a straight-line basis not to exceed 10 years. Interest is capitalized on qualifying assets under development for internal use. Maintenance and repairs are charged to operations as incurred and major improvements are capitalized. The cost of assets retired or otherwise disposed of and the accumulated depreciation thereon are removed from the accounts with any gain or loss realized upon sale or disposal charged or credited to operations. We review long-lived assets for impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event that the undiscounted future cash flows resulting from the use of the asset group is less than the carrying amount, an impairment loss equal to the excess of the assets carrying amount over its fair value, less cost to dispose, is recorded.
Goodwill and Other Intangibles	Goodwill and Other Intangibles: Goodwill represents the excess of purchase price over the fair market value of net assets acquired in connection with our business combinations. Goodwill and intangible assets that have indefinite useful lives are not amortized but are subject to annual impairment tests. We test goodwill for impairment annually in the fourth quarter or when events or changes in circumstances indicate the carrying value of this asset might exceed the current fair value. We test goodwill for impairment at the reporting unit level. We assess qualitative factors such as current company performance and overall economic factors to determine if it is more-likely-than-not that the goodwill might be impaired and whether it is necessary to perform the quantitative goodwill impairment test. In the quantitative goodwill test, a company compares the carrying value of a reporting unit to its fair value. If the carrying value of the reporting unit exceeds the estimated fair value, a second step is performed, which compares the implied fair value of goodwill to the carrying value, to determine the amount of impairment. In 2017 and 2016, we performed the qualitative assessment on both the Hub and Mode reporting units and determined it was not, more-likely-than-not, that goodwill might be impaired. We evaluate the potential impairment of finite-lived acquired intangible assets when impairment indicators exist. If the carrying value is no longer recoverable based upon the undiscounted future cash flows of the asset, the amount of the impairment is the difference between the carrying amount and the fair value of the asset.
Concentration of Credit Risk	Concentration of Credit Risk: Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We place our cash and temporary investments with high quality financial institutions in DDAs (Demand Deposit Accounts) and Savings Accounts. We primarily serve customers located throughout the United States with no significant concentration in any one region. No one customer accounted for more than 10% of revenue in 2017, 2016 or 2015. We review a customer’s credit history before extending credit. In addition, we routinely assess the financial strength of our customers and, as a consequence, believe that our trade accounts receivable risk is limited.
Revenue Recognition	Revenue Recognition: Revenue is recognized at the time 1) persuasive evidence of an arrangement exists, 2) services have been rendered, 3) the sales price is fixed and determinable and 4) collectability is reasonably assured. Revenue and related transportation costs are recognized based on relative transit time. Further, in most cases, we report our revenue on a gross basis because we are the primary obligor as we are responsible for providing the service desired by the customer. Our customers view us as responsible for fulfillment including the acceptability of the service. Service requirements may include, for example, on-time delivery, handling freight loss and damage claims, setting up appointments for pick-up and delivery and tracing shipments in transit. We have discretion in setting sales prices and as a result, the amount we earn varies. In addition, we have the discretion to select our vendors from multiple suppliers for the services ordered by our customers. Finally, we have credit risk for our receivables. These three factors, discretion in setting prices, discretion in selecting vendors and credit risk, further support reporting revenue on a gross basis for substantially all of our revenue.
Provision for Income Taxes	Provision for Income Taxes: Deferred income taxes are recognized for the future tax effects of temporary differences between financial and income tax reporting using tax rates in effect for the years in which the differences are expected to reverse. We believe that it is more likely than not that our deferred tax assets will be realized based on future taxable income projections with two exceptions for which we have established valuation allowances. We have established valuation allowances of $0.1 million related to state tax net operating losses and $1.6 million related to state incentive tax credit carryforwards. In the event the probability of realizing the remaining deferred tax assets do not meet the more likely than not threshold in the future, a valuation allowance would be established for the deferred tax assets deemed unrecoverable. Tax liabilities are recorded when, in management’s judgment, a tax position does not meet the more likely than not threshold for recognition as prescribed by the guidance. For tax positions that meet the more likely than not threshold, a tax liability may be recorded depending on management’s assessment of how the tax position will ultimately be settled. We recognize interest expense and penalties related to income tax liabilities in our provision for income taxes.
Earnings Per Common Share	Earnings Per Common Share: Basic earnings per common share are based on the average quarterly weighted average number of Class A and Class B shares of common stock outstanding. Diluted earnings per common share are adjusted for the assumed exercise of dilutive stock options and for restricted stock which are both computed using the treasury stock method.
Stock Based Compensation	Stock Based Compensation: Share-based compensation includes the restricted stock awards expected to vest based on the grant date fair value. Compensation expense is amortized straight-line over the vesting period and is included in salaries and benefits. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for employee share-based payment transactions including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification of related amounts within the statement of cash flows. The new standard became effective beginning with the first quarter of 2017. We adopted ASU 2016-09 in the first quarter of 2017 and the adoption did not have a material impact on our consolidated financial statements. We have applied the reclassification of excess tax benefits prospectively and therefore the prior period has not been adjusted. We presented in both 2016 and 2015 excess tax benefits resulting from the exercise of share-based compensation as financing cash in-flows and as operating cash out-flows in the Consolidated Statements of Cash Flows.
New Pronouncements	New Pronouncements: In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606), which will provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The new standard is effective for annual reporting periods beginning after December 15, 2017. We have been closely monitoring FASB activity related to the new standard. In the first half of 2017, we made significant progress toward completing our evaluation of the potential changes from adopting the new standard on our future financial reporting and disclosures. In the second half of 2017, we finalized our contract reviews and our detailed accounting policy. Based on our evaluation, we adopted the requirements of the new standard on January 1, 2018 and will use the full retrospective transition method. The impact of adopting Topic 606 primarily relates to recording all taxes assessed by a governmental authority that are both, imposed on and concurrent with a specific revenue-producing transaction and collected by Hub Group from a customer on a net basis, which previously were recorded on a gross basis. We expect this election to have approximately a $3.0 million impact on our consolidated financial statements in 2017 and 2016. The impact to our results is restricted to taxes because the analysis of our contracts under the new revenue recognition standard supports the recognition of revenue over time for our contracts, which is consistent with our current revenue recognition model. Revenue on the majority of our contracts will continue to be recognized over time because of the continuous transfer of control to the customer. This continuous transfer of control to the customer is supported by clauses in the contracts that allow the customer to terminate the contract for convenience or by our rights to payment for work performed to date. In addition, the number of our performance obligations under the new standard is not materially different from our contract segments under the existing standard. Lastly, the accounting for the estimate of variable consideration is not materially different compared to our current practice. The new standard clarifies how to account for principal (gross) versus agent (net) in revenue recognition. We have concluded that the adoption of this standard will not have a material impact on our consolidated financial statements. In 2016, the FASB issued new guidance which clarifies the classification of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of contingent consideration arising from a business combination, insurance settlement proceeds, and distributions from certain equity method investees. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. This standard was adopted on January 1, 2018. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business. This ASU clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. This standard was adopted on January 1, 2018 and we are evaluating the effect that this guidance will have on any future acquisitions. In 2016, the FASB issued new guidance that requires credit losses on financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, not based on incurred losses. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 is permitted. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases, which requires lessees to recognize a right-to-use asset and a lease obligation for all leases. Lessees are permitted to make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less. The new standard will become effective beginning with the first quarter of 2019. Early adoption of the standard is permitted. We plan to adopt this standard January 1, 2019, as required. We are currently evaluating the impact the adoption of this accounting guidance will have on the consolidated financial statements.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Significant estimates include the allowance for doubtful accounts, exposure under our insurance policies and useful lives of assets. Actual results could differ from those estimates.
