Fair Value Measurement

NOTE 4.

Fair Value Measurement

The carrying value of cash and cash equivalents, accounts receivable and accounts payable and long term debt approximated fair value as of March 31, 2017 and December 31, 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 March 31, 2017 and December 31, 2016, our cash and temporary investments were with high quality financial institutions in Demand Deposit Accounts (DDAs) and Savings Accounts.

Restricted investments, as of March 31, 2017 of $22.3 million and December 31, 2016 of $20.9 million, included mutual funds which are reported at fair value.

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.

- 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.

However, upon default, we have the option to purchase the tractors. We could then sell the tractors and use the proceeds to recover all or a portion of the amounts paid under the guarantees. Alternatively, we can contract with another owner-operator who would assume the lease. There were no material defaults during the quarter ended March 31, 2017 or the year ended December 31, 2016 and no potential material defaults.

We had a liability of five thousand dollars as of March 31, 2017 and nine thousand dollars as of December 31, 2016, representing the fair value for estimated defaults of the guarantees, based on a discounted cash-flow analysis which is included in current and non-current liabilities in our Consolidated Balance Sheets. We are amortizing the amounts over the remaining lives of the respective guarantees.

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, Comtrak Logistics, Inc., now known as Hub Group Trucking, Inc. Mr. Robles drove a truck for Hub Group Trucking in California, first as an independent contractor and then as an employee. The action was brought on behalf of a class comprised of present and former California-based truck drivers for Hub Group Trucking who were classified as independent contractors, from January 2009 to August 2014. The complaint alleges Hub Group Trucking has misclassified such drivers as independent contractors and that such drivers were employees. The complaint asserts various violations of the California Labor Code and claims that Hub Group Trucking has engaged in unfair competition practices. The complaint seeks, among other things, declaratory and injunctive relief, compensatory 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, Hub Group Trucking decided to make settlement offers to individual drivers with respect to the claims alleged in this lawsuit, without admitting liability. As of March 31, 2017, 93% of the California drivers have accepted the settlement offers. In late 2014, Hub Group Trucking decided to convert its model from independent contractors to employee drivers in California. In early 2016, Hub Group Trucking 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. In May 2015, the plaintiffs in the Robles case filed a Second Amended Complaint (“SAC”) which names 334 current and former Hub Group Trucking drivers as “interested putative class members.” In addition to reasserting their existing claims, the SAC includes claims post-conversion, added two new plaintiffs and seeks a judicial declaration that the settlement agreements are unenforceable. In June 2015, Hub Group Trucking filed a motion to dismiss the SAC and on July 19, 2016, Hub Group Trucking’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 on plaintiffs’ claims based on quantum merit and 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 to clarify is 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 Hub Group Trucking and five Company employees. The lawsuit alleges claims similar to those being made in Robles and seeks monetary penalties under the Private Attorneys General Act. Of the 63 named Plaintiffs, at least 58 of them previously accepted the settlement offers referenced above.

On October 29, 2015, Defendants filed a notice of removal to remove the case from state court in San Bernardino to federal court in the Central District of California. On November 19, 2015, Defendants filed a motion to transfer the case to federal court in Memphis, Tennessee and also filed a motion to dismiss the case pursuant to a clause in the independent contractor agreement stating that Tennessee law applies. Also 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. The court granted Plaintiffs’ motion to remand to the state court in San Bernardino County on April 7, 2016, mooting Defendants’ motions to transfer and dismiss.

On July 11, 2016, Defendants filed several motions in state court, asking the court to dismiss and/or stay the Plaintiffs’ suit for various reasons. During a hearing on October 5, 2016, the judge issued an oral tentative ruling stating that the choice of forum provision was unenforceable. On Defendants’ motion to dismiss the individual defendants, the court allowed for supplemental briefing for additional arguments regarding individual liability under PAGA. The court did not reach a decision regarding the motion to stay pending the outcome in Robles. Plaintiffs filed their supplemental brief on November 9, 2016 to which Defendants responded on December 6, 2016.

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.

Lubinski

On September 12, 2014, a complaint was filed in the U.S. District Court for the Northern District of Illinois (Eastern Division) by Christian Lubinski against Hub Group Trucking. The action was brought on behalf of a class comprised of present and former owner-operators providing delivery services in Illinois for Hub Group Trucking. The complaint alleged Hub Group Trucking misclassified such drivers as independent contractors and that such drivers were employees. The complaint also alleged that Hub Group Trucking made illegal deductions from the drivers’ pay and failed to properly compensate the drivers for all hours worked, reimburse business expenses, pay employment taxes, and provide workers’ compensation and other employment benefits. The complaint asserted various violations of the Illinois Wage Payment and Collections Act and claimed that Hub Group Trucking was unjustly enriched. The complaint sought, among other things, monetary damages for the relevant statutory period and attorneys’ fees.

On October 24, 2014, the Lubinski case was transferred to the U.S. District Court for the Western District of Tennessee (Western Division), in Memphis. On September 22, 2015, the court granted Hub Group Trucking’s motion to dismiss Lubinski’s Illinois law claims with prejudice based on the contractual choice of law provision, which provided that Tennessee law governed. The court denied as moot Hub Group Trucking’s motion to dismiss based on federal preemption. On October 2, 2015, Lubinski appealed this order to the United States Court of Appeals for the Sixth Circuit in Cincinnati.

On December 17, 2015, Lubinski filed his brief in support of his appeal of the motion to dismiss, asserting for the first time that the federal court did not have jurisdiction over the case due to a lack of diversity of citizenship. Hub Group Trucking filed its response brief on January 19, 2016, in part arguing that Lubinski had himself alleged diversity of citizenship in his complaint. Lubinski filed his reply brief on February 5, 2016. On April 1, 2016, the Sixth Circuit remanded the case to the district court—without ruling on the merits—for the district court “to consider the argument and admit the evidence necessary to determine the question of federal subject-matter jurisdiction.”

On July 11, 2016, with his federal district court case still pending, Lubinski filed an additional putative class action Complaint, with the same claims, in Illinois state court. On the same day, Hub Group Trucking filed a declaratory judgment complaint in Tennessee state court, seeking a declaration that Lubinski’s claims must be heard in Tennessee (based on the contractual choice-of-forum provision) and that the claims must be dismissed because Tennessee law controls and Lubinski’s claims are preempted by federal law. The parties agreed to stay all proceedings in Illinois and Tennessee state court until the federal court jurisdiction question is decided.

On October 26, 2016, Lubinski filed a motion to dismiss for lack of federal subject-matter jurisdiction and a motion for leave to file an amended complaint, attempting to “clarify” the putative class definition and arguing that the Class Action Fairness Act’s exceptions to jurisdiction apply. In early 2017, Plaintiff’s counsel advised Hub Group Trucking that Lubinski would no longer challenge federal jurisdiction. On February 15, 2017, the District Court adopted the parties’ stipulation and found that there is federal subject-matter jurisdiction. On March 22, 2017, the U.S. Court of Appeals for the Sixth Circuit granted Plaintiff’s motion to recall the mandate and reinstate Lubinski’s appeal of the district court’s order dismissing the case. The appeal was fully briefed earlier, so no further briefing will occur absent an Order from the Court of Appeals.

We cannot reasonably estimate at this time the possible loss or range of loss, if any, that may arise from the remaining unresolved claims in the above mentioned lawsuits.

We are a party to other litigation incident to our business, including claims for personal injury and/or property damage, bankruptcy preference claims, and claims regarding freight lost or damaged in transit, improperly shipped or improperly billed. Some of the lawsuits to which we are party are covered by insurance and are being defended by our insurance carriers. Some of the lawsuits are not covered by insurance and we defend those ourselves. We do not believe that the outcome of this litigation will have a materially adverse effect on our financial position or results of operations.

Accounting Changes And Error Corrections [Abstract]

New Pronouncements

NOTE 9.

New Pronouncements

In May 2014, the FASB issued Update No. 2014-09—Revenue from Contracts with Customers (Topic 606). This Standard provides guidance on how to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The FASB has recently issued several amendments to the standard, including clarification on accounting for principal vs agent and identifying performance obligations.

The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the cumulative catch-up transition method). We currently anticipate adopting the standard using the full retrospective method to restate each prior reporting period presented.

Early application is permitted for annual reporting periods beginning after December 15, 2016. We plan to adopt this standard January 1, 2018, as required.

While we are continuing to assess all potential impacts of the standard, other than additional disclosures, we do not anticipate that this standard will have a material impact on our consolidated financial statements. We have analyzed our revenue stream, began analysis of our current contracts and will continue to analyze these contracts.

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 impacts the adoption of this accounting guidance will have on the consolidated financial statements.

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.

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 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. Early adoption is permitted. We are evaluating the impact of adopting this new accounting guidance on our consolidated financial statements.

- Definition

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.
