Fair Value Measurement

NOTE 5. Fair Value Measurement

The carrying value of cash and cash equivalents, accounts receivable, accounts payable and borrowings under our revolving line of credit approximated fair value as of March 31, 2021 and December 31, 2020. As of March 31, 2021 and December 31, 2020, the fair value of the Company’s fixed-rate borrowings was $4.1 million and $6.1 million more than the historical carrying value of $243.9 million and $270.4 million, respectively. 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 March 31, 2021 and December 31, 2020, our cash and temporary investments were with high quality financial institutions in demand deposit accounts (DDAs), savings accounts and an interest bearing checking account.

Restricted investments included $21.7 million and $23.4 million as of March 31, 2021 and December 31, 2020, respectively, of mutual funds which are reported at fair value. These investments relate to our nonqualified deferred compensation plan.

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, mutual funds, 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.

Logistics. Hub’s logistics operation 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, last mile delivery, railcar and international shipping. We leverage proprietary technology along with collaborative relationships with retailers and logistics providers to deliver cost savings and performance-enhancing supply chain services to consumer-packaged goods clients. We contract with third-party warehouse providers in seven markets across North America to which our customers ship their goods to be stored and eventually consolidated, along with goods from other customers into full truckload shipments destined to major North American retailers. These services offer our customers shipment visibility, transportation cost savings, high service levels and compliance with retailers’ increasingly stringent supply chain requirements.

On December 9, 2020, we acquired NSD. NSD provides basic, residential last mile delivery services through a non-asset business model, working with a network of over 170 carriers throughout the country. The financial results of NSD since the acquisition are included in our logistics line of business.

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 service 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.

Dedicated. 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.

The following table summarizes our disaggregated revenue by business line (in thousands):

NOTE 7. 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 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 made settlement offers to individual drivers with respect to the claims alleged in this lawsuit, without admitting liability. In late 2014, HGT converted its model from independent contractors to employee drivers in California. 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.

In September 2019, the Plaintiffs’ counsel and Hub agreed in principle to settle all claims under both the Robles and Adame matters for $4.8 million, which was recorded in the third quarter of 2019 and is included in Accrued other on the accompanying Consolidated Balance Sheet. 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.

Business Combinations [Abstract]

Acquisitions

NOTE 2. Acquisition

On December 9, 2020, we acquired 100% of the equity interest of NonstopDelivery, LLC ("NSD"). Total consideration for the transaction was $104.6 million which consisted of cash paid of $89.7 million, the settlement of Hub’s accounts receivable due from NSD of $14.8 million and the true-up of certain post-closing activities of $0.1 million.

The acquisition of NSD expanded our logistics service offering to include residential last mile logistics. NSD operates through a non-asset business model, working with a network of over 170 carriers throughout the country. The financial results of NSD since the acquisition date are included in our logistics line of business.

The initial accounting for the acquisition of NSD is incomplete as we, with the support of our valuation specialist, are in the process of finalizing the fair market value calculations of the acquired net assets. In addition, the Company is in the process of reviewing the applicable future cash flows used in determining the purchase accounting. Finally, certain post-closing activities outlined in the acquisition agreement remain incomplete. As a result, the amounts recorded in the consolidated financial statements related to the NSD acquisition are preliminary and the measurement period remains open. The following table summarizes the preliminary allocation of the total consideration to the assets acquired and liabilities assumed as of the date of the acquisition (in thousands):


	December 9, 2020
Cash and cash equivalents	$	4,829
Accounts receivable trade		26,250
Prepaid expenses and other current assets		207
Property and equipment		1,018
Right of use assets - operating leases		1,295
Goodwill, net		36,388
Other intangibles		47,700
Other assets		42
Total assets acquired	$	117,729

Accounts payable trade	$	9,972
Accrued payroll		1,324
Accrued other		578
Lease liability - operating leases short-term		373
Lease liability - operating leases long-term		922
Total liabilities assumed	$	13,169

Total consideration	$	104,560

Cash paid, net	$	84,845

The NSD 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 9, 2020 with the remaining unallocated purchase price recorded as goodwill. The goodwill recognized in the NSD acquisition was primarily attributable to potential expansion and future development of the acquired business.

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


	Total
Balance at January 1, 2021	$	508,555
Acquisition		12,073
Other		(36	)
Balance at March 31, 2021	$	520,592

The changes noted as "acquisition" in the above table refer to purchase accounting adjustments related to the NSD acquisition.

The changes noted as "other" in the above table refer to the amortization of the income tax benefit of tax goodwill in excess of financial statement goodwill.

Tax history and attributes are not inherited in an equity purchase of this kind; however, the goodwill and other intangibles recognized in this purchase will be fully tax deductible over a period of 15 years.

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


			Accumulated		Balance at		Estimated Useful
	Amount		Amortization		March 31, 2021		Life
Customer relationships	$	46,200	$	1,027	$	45,173	15 years
Agent relationships	$	600	$	50	$	550	4 years
Trade name	$	900	$	200	$	700	18 months

The above intangible assets are amortized using the straight-line method. Amortization expense related to this acquisition for the three months ended March 31, 2021 was $0.8 million. The intangible assets have a weighted average useful life of approximately 14.33 years. Amortization expense related to NSD for the next five years is as follows (in thousands):


	Total
Remainder of 2021	$	2,873
2022		3,480
2023		3,230
2024		3,218
2025		3,080

The following unaudited pro forma consolidated results of operations present the effects of NSD as though it had been acquired as of January 1, 2020 (in thousands, except for per share amounts):


	Three Months Ended
	March 31, 2020
Revenue	$	854,960
Net income	$	13,789
Earnings per share
Basic	$	0.42
