Fair Value Measurement

NOTE 9. Fair Value Measurement

The carrying value of cash and cash equivalents, accounts receivable and accounts payable materially approximated fair value as of December 31, 2019 and 2018. As of December 31, 2019 and 2018, the fair value of the Company’s fixed-rate borrowings was $3.8 million and $0.4 million more than the historical carrying value of $281.6 million and $330.8 million. The fair value of the fixed-rate borrowings was estimated using an income approach based on current interest rates available to the Company for borrowings on similar terms and maturities.

We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less. As of December 31, 2019 and 2018, our cash and temporary investments were with high quality financial institutions in DDAs, savings accounts and an interest-bearing checking account.

Restricted investments included $22.6 million and $19.2 million as of December 31, 2019 and 2018, respectively, of mutual funds which are reported at fair value. These investments relate to the nonqualified deferred compensation plan that is described in Note 14.

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), or unobservable inputs (Level 3). Cash and cash equivalents, accounts receivable, accounts payable and mutual funds and related liabilities 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.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Leases [Abstract]

Leases

NOTE 12. Leases

In February 2016, the FASB issued ASC 842, Leases, (“ASC 842”) which requires lessees to recognize a right-of-use asset (“ROU”) and a lease obligation for all leases. We adopted ASC 842 as of January 1, 2019, in accordance with the standard. ASC 842 provides an option to apply the transition provisions as of the effective date. We elected this option when we adopted the new standard using a modified retrospective transition method and recognized a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented. In addition, we elected to apply a package of practical expedients and as such did not reassess at the date of initial adoption (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, or (3) initial direct costs for existing leases. Lessees can also make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less which we elected.

As of December 31, 2019, Hub has recorded $41.4 million of ROU assets and $42.0 million of Lease liabilities on our consolidated balance sheet. The lease liabilities recognized are measured based upon the present value of minimum future payments. The ROU assets are equal to lease liabilities, adjusted for prepaid and accrued rent balances which are recorded in the Consolidated Balance Sheets.

Hub currently does not have any variable lease payments that depend on an index or a rate (such as the Consumer Price Index or a market interest rate). Some leases have options to extend or terminate the agreement, which Management assesses in determining the estimated lease term. If any of the options to extend a lease are exercised, this change will be reflected as a remeasurement of the ROU asset and lease liability accordingly. As of December 31, 2019, the ROU asset and lease liabilities do not reflect any options to extend or terminate a lease as management is not reasonably certain it will exercise any of these options. Also, current leases do not contain any restrictions or covenants imposed by the leases or residual value guarantees.

Occasionally, Hub will sublease office space or parking spaces. The subleases do not relieve Hub of any of its primary obligations under the original agreement. Currently, Hub has subleases with an expected annual income totaling $0.6 million.

As of December 31, 2019, Hub signed new property lease contracts which have not commenced. Based on the present value of the lease payments, the estimated ROU assets and lease liabilities related to these contracts will total approximately $10.7 million.

Discount rates are not specified on the individual lease contracts at the commencement date. To determine the present value of the lease payments, Hub used its incremental borrowing rate which was determined based on Hub’s credit standing and factoring in the current 12-month LIBOR rate published at the time of the lease commencement. This incremental borrowing rate represents the rate of interest that Hub would have to pay to borrow on a collateralized basis over a similar term and amounts equal to the lease payments in a similar economic environment.

Goodwill and Other Intangible Assets

NOTE 7. 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 goodwill and determined it was not, more-likely-than-not, that the fair value of our reporting unit was less than its carrying value. 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):

	Total
Balance at January 1, 2018	$	319,272
Acquisition		164,976
Other		(664	)
Balance at December 31, 2018		483,584
Acquisition		1,094
Other		(219	)
Balance at December 31, 2019	$	484,459

The changes noted as “other” in the table above for both 2019 and 2018 refer to the amortization of the income tax benefit of tax goodwill in excess of financial statement goodwill and the changes in purchase accounting.

The components of the “Other intangible assets” are as follows (in thousands):

Employee Benefit Plans

NOTE 15. Employee Benefit Plans

We have a profit-sharing plan as of December 31, 2019, 2018 and 2017, under section 401(k) of the Internal Revenue Code. At our discretion, we partially match qualified contributions made by employees to the plan. We incurred expense of $3.3 million related to this plan in 2019, $2.6 million in 2018 and $2.8 million in 2017.

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, 2019 and 2018. 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 2019, 2018 and 2017. The liabilities related to these plans as of December 31, 2019 and 2018 were $22.6 million and $18.9 million, respectively.

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. We do not permanently reinvest our foreign earnings, all amounts are accrued and accounted for, though not material.

We acquired a federal net operating loss carryforward of $4.1 million through our acquisition of CaseStack in December 2018. IRS loss limitation rules allowed us to utilize $1.3 million in 2019. The remaining net operating loss of $2.8 million has no expiration date. Our state tax net operating losses total $2.1 million. Some of those state losses have no expiration date while others will expire between December 31, 2020 and December 31, 2038. Management believes it is more likely than not that the loss carryforward deferred tax assets will be realized, except for sixty-nine thousand dollars of state losses. A valuation allowance of sixty-nine thousand dollars has been established.

Our federal incentive tax credit carryforward of eighty-eight thousand dollars expires between December 31, 2025 and December 31, 2028. Our state incentive tax credit carryforwards of $6.6 million expire between December 31, 2020 and December 31, 2024. Management believes it is more likely than not that the incentive carryforward deferred tax assets will be realized, except for $4.6 million of state tax credits. A valuation allowance of $4.6 million has been established.

As of December 31, 2019 and December 31, 2018, the amount of unrecognized tax benefits was $4.1 million and $3.9 million, respectively. Of these amounts, our income tax provision would decrease $3.4 million and $3.3 million, respectively, if recognized. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

	2019			2018
Gross unrecognized tax benefits - beginning of the year	$	3,894		$	3,827
Gross increases (decreases) related to prior year tax positions		74			(397	)
Gross increases related to current year tax positions		506			959
Lapse of applicable statute of limitations		(405	)		(495	)
Gross unrecognized tax benefits - end of year	$	4,069		$	3,894

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. These amounts have been immaterial for the last three years.

In 2019, CaseStack’s federal tax return for 2016, a pre-acquisition tax year, was selected for examination by the IRS. The audit closed with no additional tax due. In 2018, Massachusetts started an audit that closed in 2019 with a refund of one thousand dollars. The Wisconsin audit of our 2014 through 2016 tax years that started in 2018 is still ongoing.

Stock-Based Compensation Plans

NOTE 14. 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, 2019, 1,252,112 shares were available for future grant under the 2017 Incentive Plan.

We have awarded time-based restricted stock to our employees and the Company’s non-employee Directors. This 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 period. In 2019 and 2018, in addition to the time-based restricted stock we granted performance-based restricted stock to our Executive Officers. The performance-based restricted stock cliff vests after the third anniversary year if certain EBITDA targets are achieved. We have not granted any stock options since 2003 and have no stock options outstanding.

Share-based compensation expense for 2019, 2018 and 2017 was $16.3 million, $13.5 million and $8.6 million or $12.1 million, $10.1 million and $5.8 million, net of taxes, respectively. Included in the 2019 share-based compensation expense is $3.4 million of performance-based share expenses or $2.6 million, net of taxes.

The following table summarizes the non-vested restricted stock activity for the year ended December 31, 2019:

In addition to the time-based restricted stock, we granted 76,500 shares of performance-based restricted stock to employees in 2019. The weighted average grant date fair value of these shares was $37.20 with a cliff vest after three years.

The fair value of non-vested restricted stock is equal to the market price of our stock at the date of grant.

The total fair value of restricted shares vested during the years ended December 31, 2019, 2018 and 2017 was $14.7 million, $13.3 million and $10.4 million, respectively.

As of December 31, 2019, there was $35.6 million of unrecognized compensation cost related to non-vested share-based compensation that is expected to be recognized over a weighted average period of 2.91 years. Additionally, as of December 31, 2019, there was $4.2 million of unrecognized compensation cost related to the non-vested performance-based restricted stock compensation that is expected to be recognized over a weighted average period of 1.5 years.

During January 2020, we granted 283,498 shares of restricted stock, which includes 75,288 performance-based shares and 208,210 time-based shares, to certain employees and 22,866 shares of restricted stock to outside directors with a weighted average grant date fair value of $52.49. The stock vests over a three to five year period for employees and one year for outside directors, except for the performance-based shares that cliff vest after three years.

Description of Business and Summary of Significant Accounting Policies

NOTE 1. Description of Business and Summary of Significant Accounting Policies

For all periods presented in our Consolidated Statements of Income and Comprehensive Income, all sales, costs, expenses, gains and income taxes attributable to Mode have been reported under the captions, “Income from Discontinued Operations, Net of Income Taxes.” Cash flows used in or provided by Mode have been reported in the Consolidated Statements of Cash Flows under operating and investing activities.

Business: Hub Group, Inc. (“Hub”, “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.

On August 31, 2018, Hub Group, Inc. sold Mode Transportation, LLC (“Mode”), a direct wholly-owned subsidiary of the Company (the “Disposition”). Refer to Note 4 “Discontinued Operations” for additional information regarding results from discontinued operations.

On December 3, 2018, we acquired CaseStack, Inc. (“CaseStack”). Refer to Note 5 “Acquisition” for additional information regarding CaseStack.

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, 2019 and 2018, our cash and temporary investments were with high quality financial institutions in demand deposit accounts (“DDAs”), savings accounts and an interest-bearing checking account.

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. Specifically, we reserve a portion of every account balance that has aged over one year, a portion of receivables that are not one year old and 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 to determine experience in collecting account balances over one year old, those that are not 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. We reserve for accounts less than one year old based on specifically identified uncollectible balances and our historic collection percentage, including receivable adjustments charged through revenue for items such as billing disputes. 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 $6.9 million and $6.7 million as of December 31, 2019 and 2018, 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 16 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 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.

Capitalized Internal Use Software and Cloud Computing Costs: We capitalize internal and external costs, which include costs related to the development of our cloud computing or hosting arrangements, incurred to develop internal use software per ASC Subtopic 350-40. Internal use software has both the of the following characteristics: the software is acquired, internally developed, or modified solely to meet our needs and during the development or modification, no substantive plan exists or is being developed to market the software externally. Only costs incurred during the application development stage and costs to develop or obtain software that allows for access to or conversion of old data by new systems are capitalized. Capitalization of costs begins when the preliminary project stage is complete, management has committed to funding the project and it is probable the project will be completed, and the software will be used to perform its intended function. The measurement of the costs to capitalize include fees paid to third parties, costs incurred to obtain software from third parties, travel expenses by employees in their duties associated with developing software, payroll related costs for employees who devote time spent directly on the project and interest costs incurred while developing internal-use software or implementing a hosting arrangement. Capitalization ceases no later than when the project is substantially complete and ready for its intended use, after all substantial testing is complete.

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. Due to the Disposition, we only have one reporting unit. We assess qualitative factors such as current company performance and overall economic factors to determine if it is more-likely-than-not that the fair value of our reporting unit was less than its carrying value 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 2019 and 2018, we performed the qualitative assessment and determined it was not, more-likely-than-not, that the fair value of our reporting unit was less than its carrying value.

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.

Claims Accruals: We purchase insurance coverage for a portion of expenses related to employee injuries, vehicular collisions, accidents, and cargo damage. Certain insurance arrangements include high self-insurance retention limits (deductible) applicable to each claim. We have umbrella policies to limit our exposure to catastrophic claim costs.

Our claims accrual policy for all self-insured claims is to recognize a liability at the time of the incident based on our analysis of the nature and severity of the claims and analyses provided by third-party claims administrators, as well as legal and regulatory factors. Our safety and claims personnel work directly with representatives from the insurance companies to continually update the estimated cost of each claim. The ultimate cost of a claim develops over time as additional information regarding the nature, timing, and extent of damages claimed becomes available. Accordingly, we use an actuarial method to develop current claim information to derive an estimate of our ultimate claim liability. This process involves the use of loss-development factors based on our historical claims experience. In doing so, the recorded liability considers future claims growth and provides an allowance for incurred-but-not-reported claims. We do not discount our estimated losses. In addition, we record receivables for amounts expected to be reimbursed for payments made in excess of self-insurance levels on covered claims. At December 31, 2019 and 2018, we had an accrual of approximately $20.0 million and $15.1 million, respectively for estimated claims. We had no significant receivables recorded for payments in excess of our self-insured levels. Our claims accruals are classified in accrued other and non-current liabilities in the consolidated balance sheets, based on when the claim is estimated to be paid.

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, savings accounts and an interest-bearing checking account. 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 2019, 2018 or 2017. 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: On January 1, 2018 we adopted the Accounting Standards Codification (ASC) topic 606, Revenue from Contracts with Customers using the full retrospective method. Under this new standard our significant accounting policy for revenue is as follows:

Revenue is recognized when we transfer services to our customer in an amount that reflects the consideration we expect to receive. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. We generally recognize revenue over time because of continuous transfer of control to the customer. Since control is transferred over time, revenue and related transportation costs are recognized based on relative transit time, which is based on the extent of progress towards completion of the related performance obligation. We enter into contracts that can include various combinations of services, which are capable of being distinct and accounted for as separate performance obligations. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. 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. These factors, discretion in setting prices and discretion in selecting vendors, further support reporting revenue on a gross basis for most 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 $4.6 million related to state incentive tax credit carryforwards. In the event the probability of realizing the remaining deferred tax assets does 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.

New Pronouncements: In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. Under this new standard, companies will no longer be required to value non-employee awards differently from employee awards. This means that companies will value all equity classified awards at their grant-date and forgo revaluing the award after this date. The standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. This standard was adopted on January 1, 2019 and had no material impact on our consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04 Intangibles – Goodwill and other (Topic 350): simplifying the test for goodwill impairment. This ASU simplifies how all entities assess goodwill for impairment by eliminating step two from the goodwill impairment test. As amended, the goodwill impairment test will consist of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The standard is effective for fiscal years beginning after December 15, 2019 and early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We adopted this standard on January 1, 2020, as required. The adoption of Topic 350 had no material effect on our financial statements.

In February 2016, the FASB issued ASC 842, Leases, which requires lessees to recognize a right-of-use asset (“ROU”) and a lease obligation for all leases. We adopted the standard as of January 1, 2019, as required. The standard also provides an additional transition method to assist entities with the implementation. Entities that elect this option would adopt the new standard using a modified retrospective transition method, but they would recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented. We elected to apply a package of practical expedients and did not reassess at the date of initial adoption (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, or (3) initial direct costs for existing leases. Lessees can also make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less which we elected.

In 2016, the FASB issued ASC 326, Financial Instruments – Credit Losses, (“ASC 326”) that requires credit losses on financial instruments 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 adopted this standard on January 1, 2020, as required. The adoption of ASC 326 had no material impact on our consolidated financial statements as the new guidance is consistent with our current accounting policy in determining expected credit losses on financial assets.

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 for claims under our insurance policies and useful lives of assets. Actual results could differ from those estimates.

Long-Term Debt and Financing Arrangements

NOTE 11. Long-Term Debt and Financing Arrangements

On July 1, 2017, we entered into a $350 million unsecured credit agreement (the "Credit Agreement").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.

We have standby letters of credit that expire in 2020. As of December 31, 2019, our letters of credit were $31.5 million.

As of December 31, 2019, we had no borrowings under our bank revolving line of credit and our unused and available borrowings were $318.5 million. Our unused and available borrowings were $323.0 million as of December 31, 2018. We were in compliance with our debt covenants as of December 31, 2019.

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.

Description of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Business	For all periods presented in our Consolidated Statements of Income and Comprehensive Income, all sales, costs, expenses, gains and income taxes attributable to Mode have been reported under the captions, “Income from Discontinued Operations, Net of Income Taxes.” Cash flows used in or provided by Mode have been reported in the Consolidated Statements of Cash Flows under operating and investing activities. Business: Hub Group, Inc. (“Hub”, “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. On August 31, 2018, Hub Group, Inc. sold Mode Transportation, LLC (“Mode”), a direct wholly-owned subsidiary of the Company (the “Disposition”). Refer to Note 4 “Discontinued Operations” for additional information regarding results from discontinued operations. On December 3, 2018, we acquired CaseStack, Inc. (“CaseStack”). Refer to Note 5 “Acquisition” for additional information regarding CaseStack.
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, 2019 and 2018, our cash and temporary investments were with high quality financial institutions in demand deposit accounts (“DDAs”), savings accounts and an interest-bearing checking account.
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. Specifically, we reserve a portion of every account balance that has aged over one year, a portion of receivables that are not one year old and 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 to determine experience in collecting account balances over one year old, those that are not 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. We reserve for accounts less than one year old based on specifically identified uncollectible balances and our historic collection percentage, including receivable adjustments charged through revenue for items such as billing disputes. 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 $6.9 million and $6.7 million as of December 31, 2019 and 2018, 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 16 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 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.
Capitalized Internal Use Software and Cloud Computing Costs	Capitalized Internal Use Software and Cloud Computing Costs: We capitalize internal and external costs, which include costs related to the development of our cloud computing or hosting arrangements, incurred to develop internal use software per ASC Subtopic 350-40. Internal use software has both the of the following characteristics: the software is acquired, internally developed, or modified solely to meet our needs and during the development or modification, no substantive plan exists or is being developed to market the software externally. Only costs incurred during the application development stage and costs to develop or obtain software that allows for access to or conversion of old data by new systems are capitalized. Capitalization of costs begins when the preliminary project stage is complete, management has committed to funding the project and it is probable the project will be completed, and the software will be used to perform its intended function. The measurement of the costs to capitalize include fees paid to third parties, costs incurred to obtain software from third parties, travel expenses by employees in their duties associated with developing software, payroll related costs for employees who devote time spent directly on the project and interest costs incurred while developing internal-use software or implementing a hosting arrangement. Capitalization ceases no later than when the project is substantially complete and ready for its intended use, after all substantial testing is complete.
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. Due to the Disposition, we only have one reporting unit. We assess qualitative factors such as current company performance and overall economic factors to determine if it is more-likely-than-not that the fair value of our reporting unit was less than its carrying value 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 2019 and 2018, we performed the qualitative assessment and determined it was not, more-likely-than-not, that the fair value of our reporting unit was less than its carrying value. 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.
Claims Accruals	Claims Accruals: We purchase insurance coverage for a portion of expenses related to employee injuries, vehicular collisions, accidents, and cargo damage. Certain insurance arrangements include high self-insurance retention limits (deductible) applicable to each claim. We have umbrella policies to limit our exposure to catastrophic claim costs. Our claims accrual policy for all self-insured claims is to recognize a liability at the time of the incident based on our analysis of the nature and severity of the claims and analyses provided by third-party claims administrators, as well as legal and regulatory factors. Our safety and claims personnel work directly with representatives from the insurance companies to continually update the estimated cost of each claim. The ultimate cost of a claim develops over time as additional information regarding the nature, timing, and extent of damages claimed becomes available. Accordingly, we use an actuarial method to develop current claim information to derive an estimate of our ultimate claim liability. This process involves the use of loss-development factors based on our historical claims experience. In doing so, the recorded liability considers future claims growth and provides an allowance for incurred-but-not-reported claims. We do not discount our estimated losses. In addition, we record receivables for amounts expected to be reimbursed for payments made in excess of self-insurance levels on covered claims. At December 31, 2019 and 2018, we had an accrual of approximately $20.0 million and $15.1 million, respectively for estimated claims. We had no significant receivables recorded for payments in excess of our self-insured levels. Our claims accruals are classified in accrued other and non-current liabilities in the consolidated balance sheets, based on when the claim is estimated to be paid.
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, savings accounts and an interest-bearing checking account. 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 2019, 2018 or 2017. 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: On January 1, 2018 we adopted the Accounting Standards Codification (ASC) topic 606, Revenue from Contracts with Customers using the full retrospective method. Under this new standard our significant accounting policy for revenue is as follows: Revenue is recognized when we transfer services to our customer in an amount that reflects the consideration we expect to receive. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. We generally recognize revenue over time because of continuous transfer of control to the customer. Since control is transferred over time, revenue and related transportation costs are recognized based on relative transit time, which is based on the extent of progress towards completion of the related performance obligation. We enter into contracts that can include various combinations of services, which are capable of being distinct and accounted for as separate performance obligations. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. 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. These factors, discretion in setting prices and discretion in selecting vendors, further support reporting revenue on a gross basis for most 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 $4.6 million related to state incentive tax credit carryforwards. In the event the probability of realizing the remaining deferred tax assets does 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.
New Pronouncements	New Pronouncements: In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. Under this new standard, companies will no longer be required to value non-employee awards differently from employee awards. This means that companies will value all equity classified awards at their grant-date and forgo revaluing the award after this date. The standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. This standard was adopted on January 1, 2019 and had no material impact on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04 Intangibles – Goodwill and other (Topic 350): simplifying the test for goodwill impairment. This ASU simplifies how all entities assess goodwill for impairment by eliminating step two from the goodwill impairment test. As amended, the goodwill impairment test will consist of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The standard is effective for fiscal years beginning after December 15, 2019 and early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We adopted this standard on January 1, 2020, as required. The adoption of Topic 350 had no material effect on our financial statements. In February 2016, the FASB issued ASC 842, Leases, which requires lessees to recognize a right-of-use asset (“ROU”) and a lease obligation for all leases. We adopted the standard as of January 1, 2019, as required. The standard also provides an additional transition method to assist entities with the implementation. Entities that elect this option would adopt the new standard using a modified retrospective transition method, but they would recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption rather than in the earliest period presented. We elected to apply a package of practical expedients and did not reassess at the date of initial adoption (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, or (3) initial direct costs for existing leases. Lessees can also make an accounting policy election to not recognize an asset and liability for leases with a term of twelve months or less which we elected. In 2016, the FASB issued ASC 326, Financial Instruments – Credit Losses, (“ASC 326”) that requires credit losses on financial instruments 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 adopted this standard on January 1, 2020, as required. The adoption of ASC 326 had no material impact on our consolidated financial statements as the new guidance is consistent with our current accounting policy in determining expected credit losses on financial assets.
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 for claims under our insurance policies and useful lives of assets. Actual results could differ from those estimates.

NOTE 16. 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 was brought on behalf of a class comprised of present and former California-based truck drivers for HGT who, from January 2009 to September 2014 were classified as independent contractors. It alleged that HGT misclassified these drivers as independent contractors and that such drivers were employees. It asserted various violations of the California Labor Code and claimed that HGT engaged in unfair competition practices. The complaint sought, 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 were only on behalf of Mr. Robles and not a putative class.

Although the Company believes that the California drivers were properly classified as independent contractors at all times because litigation is 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. 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.

Adame

On August 5, 2015, a suit was filed in state court in San Bernardino County, California on behalf of 63 named Plaintiffs against HGT and five Company employees. The lawsuit alleges claims similar to those being made in the Robles case and seeks monetary penalties under the Private Attorneys General Act. As mentioned above, plaintiffs’ counsel and Hub Group agreed in principle to settle this and the Robles matters.

Plaintiffs’ counsel and Hub agreed in principle to settle all claims under both the Robles and Adame matters for $4.8 million, which has been recorded as Accrued other in the Consolidated Balance Sheet and General and administrative costs in the Consolidated Statement of Income and Comprehensive Income. The settlements are subject to final court approval.

We are involved in certain other claims and pending litigation arising from the normal conduct of business, including putative class-action lawsuits in which the plaintiffs are current and former California-based drivers who allege claims for unpaid wages, failure to provide meal and rest periods, failure to reimburse incurred business expenses and other items. Based on management's present knowledge, management does not believe that loss contingencies arising from these pending matters are likely to have a material adverse effect on the Company's overall financial position, operating results, or cash flows after taking into account any existing accruals. However, actual outcomes could be material to the Company's financial position, operating results, or cash flows for any particular period.

Internal-use Software

NOTE 13. Internal-Use Software

In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing (Hosting) Arrangement That Is a Service Contract. The amendment aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. We adopted the amendment in the fourth quarter of 2018 and applied prospectively to all implementation costs incurred after the date of adoption. Our hosting arrangements are primarily related to our new enterprise resource planning systems.

We had total capitalized internal use software costs, which include costs related to the development of our cloud computing or hosting arrangements, net of accumulated amortization, of $64.8 million and $55.7 million as of December 31, 2019 and 2018, respectively. The 2019 balance consists of capitalized implementation costs of $14.4 million, net of accumulated amortization, related to our cloud hosting arrangements, which are classified in other assets in our consolidated balance sheet and capitalized internal-use software costs of $50.4 million, net of accumulated amortization, which are classified in property and equipment in our consolidated balance sheet. The 2018 balance consists of capitalized implementation costs of $10.1 million, net of accumulated amortization, related our cloud hosting arrangements, which are classified in other assets in our consolidated balance sheet and capitalized internal-use software costs of $45.6 million, net of accumulated amortization, which are classified in property and equipment in our consolidated balance sheet.

We capitalized total implementation and internal-use software costs of $21.9 million and $22.4 million in 2019 and 2018, respectively. Implementation and internal-use software costs are amortized, once ready for intended use, over its expected useful life or the term of the associated hosting arrangements of generally up to 10 years.

Acquisition

NOTE 5.

Acquisition

On December 3, 2018, we acquired CaseStack. Total consideration for the transaction was $252.9 million, which included $249.4 million in cash, of which $248.7 million was paid in December 2018 and $0.7 million in April 2019. There was also a deferred purchase consideration of $3.5 million. The deferred purchase consideration is included in Accrued Other in our Consolidated Balance Sheet and is being paid equally over twenty-four months.

The acquisition of CaseStack expanded our logistics service offering to include transportation and warehousing consolidation solutions for consumer packaged goods companies selling into the North American retail channel. The acquisition also added scale to our truck brokerage service offering, particularly in the less-than-truckload segment of the market.

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

Cash paid	$	249,389
Deferred purchase consideration		3,469
Total consideration	$	252,858

The following table summarizes the allocation of the total consideration to the assets acquired and liabilities assumed as of the date of the acquisition (in thousands):

Accounts receivable trade	$	31,896
Prepaid expenses and other current assets		694
Property and equipment		3,247
Deferred tax assets		6,433
Goodwill, net		166,070
Other intangibles		75,600
Other assets		120
Total assets acquired	$	284,060

Accounts payable trade	$	24,542
Accrued payroll		2,811
Accrued other		3,849
Total liabilities assumed	$	31,202

Total consideration	$	252,858

The CaseStack 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 December 3, 2018 with the remaining unallocated purchase price recorded as goodwill. The goodwill recognized in the CaseStack acquisition was primarily attributable to potential expansion and future development of the acquired business.

Tax history and attributes including net operating loss carryovers and other deferred tax assets are inherited in an equity purchase such as this, while goodwill is not tax deductible.

We incurred approximately $1.4 million of transaction 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, 2018.

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

			Accumulated		Balance at		Estimated Useful
	Amount		Amortization		December 31, 2019		Life
Customer relationships - logistics services	$	65,600	$	7,107	$	58,493	10 years
Customer relationships - transportation services	$	8,700	$	1,885	$	6,815	5 years
Trade name	$	1,300	$	939	$	361	18 months

The above intangible assets are amortized using the straight -line method. Amortization expense related to this acquisition was $9.2 million and $0.8 million for 2019 and 2018, respectively. The intangible assets have a weighted average useful life of approximately 8 years. Amortization expense related to CaseStack for the next five years is as follows (in thousands):

	Total
Year 1	$	8,661
Year 2		8,300
Year 3		8,300
Year 4		8,155
Year 5		6,560

From the date of the acquisition through December 31, 2018, CaseStack’s revenue was $20.8 million and operating income of $0.7 million.

The following unaudited pro forma consolidated results of operations presents the effects of CaseStack and Dedicated as though it had been acquired as of January 1, 2017 (in thousands, except for per share amounts):

Earnings per share is from continuing operations.

The unaudited pro forma consolidated results for the annual periods were prepared using the acquisition method of accounting and are based on the historical financial information of Hub, Dedicated and CaseStack. The historical financial information has been adjusted to give effect to the pro forma adjustments that are: (i) directly attributable to the acquisition, (ii) factually supportable and (iii) expected to have a continuing impact on the combined results. The unaudited pro forma consolidated results are not necessarily indicative of what our consolidated results of operations actually would have been had we completed the acquisitions on January 1, 2017.

NOTE 4.

Discontinued Operations

On August 31, 2018, Hub sold Mode. Total consideration received by the Company for the Disposition in the third quarter of 2018 was $238.5 million in cash, subject to customary purchase price adjustments. An additional $19.4 million receivable resulting from a net working capital adjustment was recorded in other receivables in the Consolidated Balance Sheet in the fourth quarter of 2018 and was received in the first quarter of 2019.

During the eight months we owned Mode in 2018, Mode had revenue of $42.2 million from Hub and Hub had revenue of $17.9 million from Mode. For the twelve months ended December 31, 2017, Mode had revenue of $50.6 million from Hub and Hub had $51.0 million from Mode. These sales were eliminated on our Consolidated Statements of Income. In connection with the Disposition, the Company and Mode entered into a transition services agreement pursuant to which both the Company and Mode provided certain immaterial transition services to the other party for a period of time following the closing.

Results associated with Mode are classified as income from discontinued operations, net of income taxes, in our Consolidated Statements of Income. Prior year results have been adjusted to conform with the current presentation. Income from discontinued operations is comprised of the following:

Revenue From Contract With Customer [Abstract]

Revenue from Contracts with Customers

NOTE 6. Revenue from Contracts with Customers

On January 1, 2018, we adopted the Accounting Standards Codification (ASC) topic 606, Revenue from Contracts with Customers. See Note 1 – Description of Business and Summary of Significant Accounting Policies for significant accounting policy for revenue.

The Company capitalizes commissions incurred in connection with obtaining a contract. The Company capitalized commissions associated with dedicated services of $0.1 million and $0.2 million at December 31, 2019 and 2018, respectively. Capitalized commission fees are amortized based on the transfer of services to which the assets relate and are included in selling, general and administrative expenses. Amortization expense was approximately $0.1 million in both 2019 and 2018.

Costs incurred to obtain an intermodal, truck brokerage or logistics contract are expensed as incurred according to the practical expedient that allows contract acquisition costs to be recognized immediately if the deferral period is one year or less.

The Company applied Topic 606 retrospectively using the practical expedient in paragraph 606-10-65-1(f)(3), under which the Company does not disclose the amount of consideration allocated to the remaining performance obligations or an explanation of when the Company expects to recognize that amount as revenue for all reporting periods presented before January 1, 2018. We do not generally have a remaining performance obligation due to revenue generally being recognized using relevant transit time. We only had one significant accounting policy change that is disclosed below.

Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by Hub from a customer were previously recorded on a gross basis. Under Topic 606, these taxes are excluded from revenue. This change had an effect of $3.0 million on revenue and transportation costs for the twelve months ended December 31, 2017.

Hub offers comprehensive multimodal solutions including intermodal, truck brokerage, logistics and dedicated services. Hub has full time employees located throughout the United States, Canada and Mexico.

Intermodal. As an intermodal provider, we arrange for the movement of our customers’ freight in containers and trailers, typically over long distances of 750 miles or more. We contract with railroads to provide transportation for the long-haul portion of the shipment between rail terminals. Local pickup and delivery services between origin or destination and rail terminals (referred to as “drayage”) are provided by our HGT subsidiary and third-party local trucking companies.

Truck Brokerage. We operate one of the largest truck brokerage operations, providing customers with an over the road service option for their transportation needs. Our brokerage does not operate any trucks; instead we match customers’ needs with carriers’ capacity to provide the most effective service and price combination. We have contracts with a substantial base of carriers allowing us to meet the varied needs of our customers.

Logistics. Hub’s logistics business operates under the names Unyson Logistics and CaseStack. Unyson Logistics is comprised of a network of logistics professionals dedicated to developing, implementing and operating customized logistics solutions for customers. Unyson Logistics offers a wide range of transportation management services and technology solutions including shipment optimization, load consolidation, mode selection, carrier management, load planning and execution and web-based shipment visibility. Our multi-modal transportation capabilities include small parcel, heavyweight, expedited, less-than-truckload, truckload, intermodal, railcar and international shipping. Our CaseStack logistics business leverages proprietary technology along with collaborative partnerships with retailers and logistics providers to deliver cost savings and performance-enhancing supply chain services to consumer-packaged goods clients. CaseStack contracts with third-party warehouse providers in seven markets across North America to which its customers ship their goods to be stored and eventually consolidated, along with goods from other CaseStack customers, into full truckload shipments destined to major North American retailers. CaseStack offers its customers shipment visibility, transportation cost savings, high service and compliance with retailers’ increasingly stringent supply chain requirements.

Dedicated Trucking. Our dedicated operation contracts with customers who seek to outsource a portion of their trucking transportation needs. We offer a dedicated fleet of equipment and drivers to each customer, as well as the management and infrastructure to operate according to the customer’s high service expectations. Contracts with customers generally include fixed and variable pricing arrangements and may include charges for early termination which serves to reduce the financial risk we bear with respect to the utilization of our equipment.

Certain prior year revenue amounts by line of business have been reclassified to conform with current year presentation.
