| Summary of Significant Accounting Policies |
Universal Logistics Holdings, Inc. (“Universal” or the “Company”), through its subsidiaries, is a leading asset-light provider of customized transportation and logistics solutions throughout the United States, and in Mexico, Canada and Colombia. We provide our customers with supply chain solutions that can be scaled to meet their changing demands. We offer our customers a broad array of services across their entire supply chain, including truckload, brokerage, intermodal, dedicated and value-added services. Our customized solutions and flexible business model are designed to provide us with a highly variable cost model.
The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions relating to these entities have been eliminated. Our fiscal year consists of four quarters, each with thirteen weeks. Certain immaterial reclassifications have been made to the prior consolidated financial statements in order for them to conform to the December 31, 2017 presentation, including the reclassification of revenue categories to reflect Universal’s service offering. These reclassifications had no effect on reported consolidated net income, comprehensive income, earnings per common share, cash flows, total assets, or stockholders' equity as previously reported.
The preparation of the consolidated financial statements requires management of the Company to make a number of estimates and assumptions related to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include the fair value of assets and liabilities acquired in business combinations; carrying amounts of property and equipment and intangible assets; marketable securities; valuation allowances for receivables; and liabilities related to insurance and claim costs. Actual results could differ from those estimates.
We consider all highly liquid investments, purchased with a maturity of three months or less, to be cash equivalents. Accounts at banks with an aggregate excess of the amount of checks issued over cash balances are included as accounts payable in current liabilities in the consolidated balance sheets, and changes in such accounts are reported as cash flows from operating activities in the consolidated statements of cash flows.
At December 31, 2017 and 2016, marketable securities, all of which are available-for-sale, consist of common and preferred stocks. Marketable securities are carried at fair value, with unrealized gains and losses, net of related income taxes, reported as accumulated other comprehensive income (loss), except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net income and are included in other non-operating income (expense), at which time the average cost basis of these securities are adjusted to fair value. Fair values are based on quoted market prices at the reporting date. Interest and dividends on available-for-sale securities are included in other non-operating income (expense). During the years ended December 31, 2017, 2016 and 2015, we received proceeds of $1.3 million, $0.9 million and $0.4 million from the sale of marketable securities with a combined cost of $0.3 million, $0.5 million and $0.1 million resulting in a realized gain of $0.9 million, $0.4 million and $0.3 million, respectively. We plan to adopt Accounting Standards Update (“ASU”) 2016-01 effective as of January 1, 2018. See Note 17 “Recent Accounting Pronouncements” for further information regarding the adoption.
The cost, gross unrealized holding gains, gross unrealized holding losses, and fair value of available-for-sale securities by type were as follows (in thousands):
Included in equity securities at December 31, 2017 were securities with a book basis of $3.0 million and a cumulative loss position of $0.5 million, the impairment of which we consider to be temporary. Equity securities at December 31, 2016 included securities with a book basis of $3.5 million and temporary impairments of $0.6 million. We consider several factors in determining as to whether declines in value are judged to be temporary or other-than-temporary, including the severity and duration of the decline, the financial condition and near-term prospects of the specific issuers and the industries in which they operate, and our intent and ability to hold these securities. We may incur future impairment charges if declines in market values continue and/or worsen and impairments are no longer considered temporary. The fair value and gross unrealized holding losses of our marketable securities that are not deemed to be other-than-temporarily impaired aggregated by type and length of time they have been in a continuous unrealized loss position were as follows (in thousands):
At December 31, 2017, our portfolio of equity securities in a continuous loss position, the impairment of which we consider to be temporary, consists primarily of common stocks in the oil and gas, banking, transportation, communication, and pharmaceutical industries. The fair value and unrealized losses are distributed in 20 publicly traded companies, with no single industry or company representing a material or concentrated unrealized loss. We have evaluated the near-term prospects of the various industries, as well as the specific issuers within our portfolio, in relation to the severity and duration of the impairments, and based on that evaluation, and our ability and intent to hold these investments for a reasonable period of time to allow for a recovery of fair value, we do not consider these investments to be other-than-temporarily impaired at December 31, 2017.
Accounts receivable are recorded at the net invoiced amount, net of an allowance for doubtful accounts, and do not bear interest. They include unbilled amounts for services rendered in the respective period but not yet billed to the customer until a future date, which typically occurs within one month. In order to reflect customer receivables at their estimated net realizable value, we record charges against revenue based upon current information. These charges generally arise from rate changes, errors, and revenue adjustments that may arise from contract disputes or differences in calculation methods employed by the customer. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on historical write-off experience and the aging of our outstanding accounts receivable. Balances are considered past due based on invoiced terms. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. We do not have any off‑balance‑sheet credit exposure related to our customers. Accounts receivable from affiliates are shown separately and include trade receivables from the sale of services to affiliates.
Included in prepaid expenses and other is inventory used in a portion of our value-added service operations. Inventories are stated net realizable value. Cost is determined using the first-in, first-out method. Provisions for excess and obsolete inventories are based on our assessment of excess and obsolete inventory on a product-by-product basis. At December 31, inventory consists of the following (in thousands):
Property and equipment, including leasehold improvements, are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:
The amounts recorded for depreciation expense were $41.0 million, $29.2 million, and $25.8 million for the years ended December 31, 2017, 2016 and 2015, respectively. Tire repairs, replacement tires, replacement batteries, consumable tools used in our logistics services, and routine repairs and maintenance on vehicles are expensed as incurred. Parts and fuel inventories are included in prepaid expenses and other. We capitalize certain costs associated with vehicle repairs and maintenance that materially extend the life or increase the value of the vehicle or pool of vehicles.
Intangible assets subject to amortization consist of customer contracts and agent and customer relationships that have been acquired in business combinations. These assets are amortized either over the period of economic benefit or on a straight-line basis over the estimated useful lives of the related intangible asset. The estimated useful lives of these intangible assets range from three to nineteen years. The useful lives of acquired trademarks are indefinite and, therefore, not subject to amortization. Our identifiable intangible assets as of December 31, 2017 and 2016 are as follows (in thousands):
Estimated amortization expense by year is as follows (in thousands):
The amounts recorded for amortization expense were $6.0 million, $7.5 million, and $9.2 million for the years ended December 31, 2017, 2016 and 2015, respectively.
Goodwill represents the excess purchase price over the fair value of assets acquired in connection with the Company’s acquisitions. Under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification, or ASC, Topic 350 “Intangibles – Goodwill and Other”, we are required to test goodwill for impairment annually (in our third fiscal quarter) or more frequently, whenever events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit with goodwill below its carrying amount. We have the option to first assess qualitative factors such as current performance and overall economic conditions to determine whether or not it is necessary to perform a quantitative goodwill impairment test. If we choose that option, then we would not be required to perform a quantitative goodwill impairment test unless we determine that, based on a qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying value. If we determine that it is more likely than not, or if we choose not to perform a qualitative assessment, we then proceed with the quantitative assessment. Under the quantitative test, if the fair value of a reporting unit exceeds its carrying amount, then goodwill of the reporting unit is considered to not be impaired. If the carrying amount of the reporting unit exceeds its fair value, then an impairment loss is recognized in an amount equal to the excess, up to the value of the goodwill. During the third quarter of 2017, we completed our goodwill impairment testing by performing a quantitative assessment. Based on the results of this test, no impairment loss was recognized. At both December 31, 2017 and 2016, the carrying amount of goodwill was $74.5 million, of which $18.2 million was recorded in our transportation segment and $56.3 million in our logistics segment.
Long-lived assets, other than goodwill and indefinite lived intangibles such as property and equipment and purchased intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group may not be recoverable. If circumstances require a long-lived asset to be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by a long-lived asset or group to its carrying value. If the carrying value of the long-lived asset or group is deemed to not be recoverable on an undiscounted cash flow basis, an impairment charge is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market prices and independent third-party appraisals. Changes in management’s judgment relating to salvage values and/ or estimated useful lives could result in greater or lesser annual depreciation expense or impairment charges in the future. Indefinite lived intangibles are tested for impairment annually by comparing the carrying value of the assets to their fair value.
Contingent consideration arrangements granted in connection with a business combination are evaluated to determine whether contingent consideration is, in substance, additional purchase price of an acquired enterprise or compensation for services, use of property or profit sharing. Additional purchase price is added to the fair value of consideration transferred in the business combination and compensation is included in operating expenses in the period it is incurred. Contingent consideration related to additional purchase price is measured to fair value at each reporting date until the contingency is resolved.
For cash equivalents, accounts receivables, accounts payable, and accrued expenses, the carrying amounts are reasonable estimates of fair value as the assets are readily redeemable or short‑term in nature and the liabilities are short-term in nature. Marketable securities, consisting of equity securities, are carried at fair market value as determined by quoted market prices. Our revolving credit and term loan agreements consist of variable rate borrowings. The carrying value of these borrowings approximates fair value because the applicable interest rates are adjusted frequently based on short-term market rates. For our equipment promissory notes, the fair values are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. See Note 6 “Fair Value Measurement and Disclosures” for further information.
Deferred compensation relates to our bonus plans. Annual bonuses may be awarded to certain operating, sales and management personnel based on overall Company performance and achievement of specific employee or departmental objectives. Such bonuses are typically paid in annual installments over a five-year period. All bonus amounts earned by and due to employees in the current year are included in accrued expenses and other current liabilities. Those that are payable in subsequent years are included in other long-term liabilities.
Our customers may discontinue or alter their business activity in a location earlier than anticipated, prompting us to exit a customer-dedicated facility. We recognize exit costs associated with operations that close or are identified for closure as an accrued liability in the Consolidated Balance Sheets. Such charges include lease termination costs, employee termination charges, asset impairment charges, and other exit-related costs associated with a plan approved by management. If we close an operating facility before its lease expires, costs to terminate a lease are recognized when an early termination provision is exercised, or we record a liability for non-cancellable lease obligations based on the fair value of remaining lease payments, reduced by any existing or prospective sublease rentals. Employee termination costs are recognized in the period that the closure is communicated to affected employees. The recognition of exit and disposal charges requires us to make certain assumptions and estimates as to the amount and timing of such charges. Subsequently, adjustments are made for changes in estimates in the period in which the change becomes known.
We are the primary obligor when rendering truckload, brokerage, intermodal, dedicated and value-added services, and assume the corresponding credit risk with customers. We have discretion in setting sales prices and, as a result, our earnings may vary. In addition, we have discretion to choose and negotiate terms with our multiple suppliers for the services ordered by our customers. This includes owner-operators with whom we contract to deliver our transportation services. As such, revenue and the related purchased transportation and commissions are recognized on a gross basis when persuasive evidence of an arrangement exists, delivery has occurred at the receiver’s location or for service arrangements after the related services have been rendered, the revenue and related expenses are fixed or determinable and collectability is reasonably assured. Fuel surcharges, where separately identifiable, of $59.5 million, $50.9 million and $75.7 million for the years ended December 31, 2017, 2016 and 2015, respectively, are included in operating revenues. Revenues and associated costs for the sales of axles and machined components are recognized when title has passed and the risks and rewards of ownership are transferred, which is at the time of shipment. Our customer contracts could involve multiple revenue-generating activities performed for the same customer. When several contracts are entered into with the same customer in a short period of time, we evaluate whether these contracts should be considered as a single, multiple element contract for revenue recognition purposes. Criteria we consider that may result in the aggregation of contracts include whether such contracts are actually entered into within a short period of time, whether services in multiple contracts are interrelated, or if the negotiation and terms of one contract show or include consideration for another contract or contracts. Our current contracts have not been required to be aggregated, as they are negotiated independently on a standalone basis. Our customers typically choose their vendor and award business at the conclusion of a competitive bidding process for each service. As a result, although we evaluate customer purchase orders and agreements for multiple elements and aggregation of individual contracts into a multiple element arrangement, our current contracts do not meet the criteria required for multiple element contract accounting. We adopted Accounting Standards Update (“ASU”) 2014-09 effective as of January 1, 2018, as further described in Note 17 “Recent Accounting Pronouncements”. The adoption of this standard will change the timing of revenue recognition for our transportation services businesses, which include truckload, brokerage, intermodal and dedicated services, from at delivery to over-time as the performance obligations on the in-transit services are completed. For our value-added service businesses, the adoption of the standard will not change the timing of revenue recognition. (1)Summary of Significant Accounting Policies—continued
Insurance and claims expense represents charges for premiums and the accruals made for claims within our self-insured retention amounts. The accruals are primarily related to auto liability, general liability, cargo and equipment damage, and service failure claims. A liability is recognized for the estimated cost of all self-insured claims including an estimate of incurred but not reported claims based on historical experience and for claims expected to exceed our policy limits. We may also make accruals for personal injury and property damage to third parties, and workers’ compensation claims if a claim exceeds our insurance coverage. Such accruals are based upon individual cases and estimates of ultimate losses, incurred but not reported losses, and losses arising from known claims ultimately settling in excess of insurance coverage using loss development factors based upon industry data and past experience. Since the reported accrual is an estimate, the ultimate liability may be materially different from the amount recorded. If adjustments to previously established accruals are required, such amounts are included in operating expenses in the current period. We maintain insurance with licensed insurance carriers. Legal expenses related to auto liability claims are covered under our insurance policy. We are responsible for all other legal expenses related to claims. In brokerage arrangements, our exposure to liability associated with accidents incurred by other third-party carriers, who haul freight on our behalf, is reduced by various factors including the extent to which the third party providers maintain their own insurance coverage. Our insurance expense varies primarily based upon the frequency and severity of our accident experience, insurance rates, coverage limits, and self-insured retention amounts.
We record compensation expense for the grant of stock based awards. Compensation expense is measured at the grant date, based on the calculated fair value of the award, and recognized as an expense over the requisite service period (generally the vesting period of the grant). See Note 12 “Stock Based Compensation” for further information.
Deferred income taxes are provided for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. See Note 8 “Income Taxes” for further information on the impact of the Tax Cuts and Jobs Act (the “Tax Cuts and Jobs Act”) signed into law on December 22, 2017. We are no longer subject to U.S. federal income tax examinations by tax authorities for years before 2013. In addition, we file income tax returns in various state, local and foreign jurisdictions. Historically, we have been responsible for filing separate state, local and foreign income tax returns for our self and our subsidiaries. We are no longer subject to state or foreign jurisdiction income tax examinations for years before 2012 and 2011, respectively. We recognize the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We recognize interest related to unrecognized tax benefits in income tax expense and penalties in other operating expenses.
The financial statements of the Company’s subsidiaries operating in Mexico, Canada and Colombia are prepared to conform to U.S. GAAP and translated into U.S. Dollars by applying a current exchange rate. The local currency has been determined to be the functional currency. Items appearing in the Consolidated Statements of Income are translated using average exchange rates during each period. Assets and liabilities of international operations are translated at period-end exchange rates. Translation gains and losses are reported in accumulated other comprehensive income (loss) as a component of shareholders’ equity.
We report our financial results in two reportable segments, the transportation segment and the logistics segment, based on the nature of the underlying customer commitment and the types of investments required to support these commitments. This presentation reflects the manner in which management evaluates our operating segments, including an evaluation of economic characteristics and applicable aggregation criteria. Operations aggregated in our transportation segment are associated with individual freight shipments coordinated by our agents, company-managed terminals and specialized services operations. In contrast, operations aggregated in our logistics segment deliver value-added services or transportation services to specific customers on a dedicated basis, generally pursuant to contract terms of one year or longer. Other non-reportable operating segments are comprised of the Company’s subsidiaries that provide support services to other subsidiaries and to owner-operators, including shop maintenance and equipment leasing.
Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash and cash equivalents, marketable securities and accounts receivable. We maintain our cash and cash equivalents and marketable securities with high quality financial institutions. We perform ongoing credit evaluations of our customers and generally do not require collateral. Our customers are generally concentrated in the automotive, wind energy, building materials, machinery and metals industries. During the fiscal years ended December 31, 2017, 2016 and 2015, aggregate sales in the automotive industry totaled 40%, 43% and 37% of revenue, respectively. In 2017, 2016 and 2015, General Motors accounted for approximately 16%, 18% and 11% of our total operating revenues, respectively. In 2017, sales to our top 10 customers, including General Motors, totaled 40%. |

| Accounts Receivable |
Accounts receivable amounts appearing in the consolidated financial statements include both billed and unbilled receivables. We bill customers in accordance with contract terms, which may result in a brief timing difference between when revenue is recognized and when invoices are rendered. Unbilled receivables, which usually are billed within one month, totaled $26.2 million and $16.4 million at December 31, 2017 and 2016, respectively. Accounts receivable are presented net of an allowance for doubtful accounts. Following is a summary of the activity in the allowance for doubtful accounts for the years ended December 31 (in thousands):

| Debt |
Debt is comprised of the following (in thousands):
(1) The ABL Facility provides for maximum borrowings of $120 million at a variable rate of interest based on LIBOR or a base rate, and matures on December 23, 2020. The facility, which is secured by cash, deposits and accounts receivable of the borrowing subsidiaries, includes customary affirmative and negative covenants and events of default, as well as financial covenants requiring a minimum fixed charge coverage ratio to be maintained after a triggering event. Interest on base rate advances is payable quarterly, and interest on each LIBOR-based advance is payable on the last day of the applicable interest period. At December 31, 2017, we were in compliance with all covenants under the Facility, and $32.0 million was available for borrowing. (2) The Westport Facility provides our subsidiary, Westport Axle Corporation, with maximum borrowings of $60 million in the form of a $40 million term loan and a $20 million revolver. Borrowings under the Westport Facility, which matures on December 23, 2020, accrue interest at a variable interest rate based on LIBOR or a base rate, and are secured by all of Westport’s assets. The Company becomes a guarantor upon the occurrence of certain events specified in the Westport Facility. Borrowings are repaid in part quarterly with the balance due at maturity. Interest on base rate advances is payable quarterly, and interest on each LIBOR-based advance is payable on the last day of the applicable interest period. The Westport Facility includes customary affirmative and negative covenants and events of default. At December 31, 2017, we were in compliance with all covenants, and $10.5 million was available for borrowing. (3) The Equipment Financing consists of a series of promissory notes issued by a wholly-owned subsidiary in order to finance transportation equipment. The equipment notes, which are secured by liens on selected titled vehicles, include certain affirmative and negative covenants and are generally payable in 60 monthly installments and bear interest at fixed rates ranging from 3.18% to 4.22%. At December 31, 2017, we were in compliance with all covenants.
(4) The Real Estate Financing consists of a series of promissory notes issued by a wholly-owned subsidiary in order to finance certain real property. The promissory notes, which are secured by first mortgages and assignment of leases on specific parcels of real estate and improvements, include certain affirmative and negative covenants and are generally payable in 120 monthly installments. Each of the notes bears interest at LIBOR plus 2.25%. At December 31, 2017, we were in compliance with all covenants. (5) The Margin Facility is a short-term line of credit secured by our portfolio of marketable securities. It bears interest at LIBOR plus 1.10%. The amount available under the line of credit is based on a percentage of the market value of the underlying securities. We did not have any amounts outstanding under our line of credit at December 31, 2017 or 2016, and the maximum available borrowings under the line of credit were $8.9 million and $7.0 million, respectively. The following table reflects the maturities of our principal repayment obligations as of December 31, 2017 (in thousands):
The Company is also party to three interest rate swap agreements that qualify for hedge accounting. The swap agreements were executed to fix a portion of the interest rates on its variable rate debt that have a combined notional amount of $27.7 million at December 31, 2017. Under two of the swap agreements, the Company receives interest at the one-month LIBOR rate plus 2.25%, and pays a fixed rate. The March 2016 swap (swap A) became effective October 2016, has a rate of 4.16% (amortizing notional amount of $10.0 million) and expires July 2026, and an additional March 2016 swap (swap B) became effective October 2016, has a rate of 3.83% (amortizing notional amount of $5.7 million) and expires May 2022. The third interest rate swap agreement (swap C) has a notional amount of $12.0 million and expired February 2018. Under swap C, the Company receives interest at the one-month LIBOR rate, and pays a fixed rate of 0.78%. At December 31, 2017, the fair value of the three swap agreements was an asset of $0.3 million. Since these swap agreements qualify for hedge accounting, the changes in fair value are recorded in other comprehensive income (loss), net of tax. See Note 6, “Fair Value Measurement and Disclosures” for additional information pertaining to interest rate swaps. |

| Fair Value Measurement and Disclosures |
ASC Topic 820, “Fair Value Measurements and Disclosures”, defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date and expanded disclosures with respect to fair value measurements. ASC Topic 820 also establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:
We have segregated all financial assets that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the tables below (in thousands):
The valuation techniques used to measure fair value for the items in the tables above are as follows:
Our revolving credit and term loan agreements and our real estate promissory notes all consists of variable rate borrowings. We categorize borrowings under these credit agreements as Level 2 in the fair value hierarchy. The carrying value of these borrowings approximate fair value because the applicable interest rates are adjusted frequently based on short-term market rates. For our equipment promissory notes with fixed rates, the fair values are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. We categorize borrowings under this credit agreement as Level 2 in the fair value hierarchy. The carrying values and estimated fair values of these promissory notes at December 31, 2017 is summarized as follows:
We have not elected the fair value option for any of our financial instruments. |

| Transactions with Affiliates |
CenTra, Inc., an affiliate of the Company, provides administrative support services to Universal in the ordinary course of business, including legal, human resources, tax, and IT infrastructure and related services. The cost of these services is based on the actual or estimated utilization of the specific service. Universal also purchases other services from affiliates. Following is a schedule of cost incurred and included in operating expenses for services provided by affiliates for the years ended December 31 (in thousands):
We pay CenTra the direct variable cost of maintenance, fueling and other operational support costs for services delivered at our affiliate’s trucking terminals that are geographically remote from our own facilities. Such costs are billed when incurred, paid on a routine basis, and reflect actual labor utilization, repair parts costs or quantities of fuel purchased. In connection with our transportation services, we also pay tolls and other fees for international bridge crossings to certain related entities which are under common control with CenTra. A significant number of our operating locations are located in facilities leased from affiliates. At 36 facilities, occupancy is based on either month-to-month or contractual, multi-year lease arrangements which are billed and paid monthly. Leasing properties provided by an affiliate that owns a substantial commercial property portfolio affords us significant operating flexibility. However, we are not limited to such arrangements. See Note 9, “Leases” for further information regarding the cost of leased properties. We purchase workers’ compensation, property and casualty, cargo, warehousing and other general liability insurance from an insurance company controlled by our majority shareholders. Our employee health care benefits and 401(k) programs are also provided by this affiliate. Other services from affiliates, including contracted transportation services, are delivered to us on a per-transaction-basis or pursuant to separate contractual arrangements provided in the ordinary course of business. At December 31, 2017 and 2016, amounts due to affiliates were $12.0 million and $4.6 million, respectively. In our Consolidated Balance Sheets, we record our insured claims liability and the related recovery from an affiliate insurance provider in insurance and claims, and other receivables. At December 31, 2017 and 2016, there were $10.1 million and $8.7 million, respectively, included in each of these accounts for insured claims. During 2016 and 2017, we made purchases totaling $2.3 million and $2.1 million, respectively, for wheels and tires for new trailering equipment. We also purchased 64 used tractors from an affiliate in 2017 for $1.8 million. In 2016, we contracted with an affiliate to provide real property improvements to us totaling $1.0 million, and purchased an additional $0.2 million in revenue equipment components during the same period. We periodically use the law firm of Sullivan Hincks & Conway to provide legal services. Daniel C. Sullivan, a member of our Board, is a partner at Sullivan Hincks & Conway. Not included in the table above are amounts paid for legal services during 2017 and 2015 of $1,400 and $1,500, respectively. No amounts were paid for legal services during 2016. During 2017, we exercised our right of first refusal to acquire 17,500 shares of restricted stock from a director, H. E. “Scott” Wolfe, for $385,000 based on the closing market price on the effective date of the transaction. In 2016, we purchased a multi-building, cross-dock logistics terminal located in Romulus, Michigan from a subsidiary of CenTra, Crown Enterprises, Inc. The purchase price, which was established by an independent third party appraisal, was $22.5 million payable pursuant to a promissory note issued to Crown. At December 31, 2016, the promissory note was fully repaid.
Services provided by Universal to Affiliates We periodically assist our affiliates by providing selected transportation and logistics services in connection with their specific customer contracts or purchase orders. Truck fueling and administrative expenses are presented net in operating expense. Following is a schedule of services provided to CenTra and affiliates for the years ended December 31 (in thousands):

A summary of income (loss) related to U.S. and non-U.S. operations are as follows (in thousands):
The provision (benefit) for income taxes attributable to income from continuing operations for the years ended December 31 consists of the following (in thousands):
On December 22, 2017, the Tax Cuts and Jobs Act was signed into law, significantly changing the U.S. tax code by providing for, among other things, lower corporate income tax rates and requiring companies to pay a one-time transition tax on deemed repatriated earnings of foreign subsidiaries. Effective January 1, 2018, the Tax Cuts and Jobs Act permanently reduced the U.S. corporate income tax rate from 35% to 21%. In accordance with U.S. GAAP, the reduction in the enacted rate caused the Company to revalue its ending net deferred tax assets and liabilities and caused the Company to record a provisional tax benefit of $18.2 million in its consolidated financial statements for the year ended December 31, 2017. With respect to the transition tax on deemed repatriated foreign earnings, the Company determined that, based upon information currently available, the transition tax did not have a material impact on its results of operations, financial position or cash flows.
On December 22, 2017, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”). SAB 118 provides guidance on the accounting for the tax effect of the Tax Cuts and Jobs Act in situations when a company does not have all necessary information available, prepared, or analyzed in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts and Jobs Act. SAB 118 allows for a measurement period not to exceed one year from the enactment of the Tax Cuts and Jobs Act for companies to complete their analysis. The Company recognized the provisional impact related to the revaluation of deferred tax assets and liabilities in its December 31, 2017 consolidated financial statements and determined that there was no material impact from the transition tax; however, the ultimate impact may differ materially due to additional analysis, changes in interpretations and assumptions, or additional regulatory guidance that may be issued. Deferred income tax assets and liabilities at December 31 consist of the following (in thousands):
In assessing whether deferred tax assets may be realized in the future, management considers whether it is more likely than not that some portion of such tax assets will not be realized. The deferred tax assets and liabilities were reviewed separately by jurisdictions when measuring the need for valuation allowances. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (both ordinary income and taxable capital gains) during the periods in which those temporary differences reverse. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Valuation allowances are established when necessary to reduce deferred tax assets when it is more likely than not that a portion or all of the deferred tax assets will not be realized. Based upon the level of historical taxable income, reversal of existing taxable temporary differences, projections for future taxable income over the periods in which the domestic deferred tax assets are expected to reverse, and our ability to generate future capital gains, management believes it is more likely than not that we will realize the benefits of these deductible differences. Thus, no valuation allowance has been established for the domestic deferred tax assets. We had foreign net operating loss carryforward associated with our Mexican subsidiary with a tax effect of $3.2 million as of December 31, 2017. The net operating loss carryforward will expire in 2027. Although realization is not assured, the Company has concluded that it is more likely than not that the deferred tax asset will be fully realized and as such no valuation allowance has been provided. At December 31, 2017, we had foreign net operating loss carryforward associated with our German subsidiary with a tax effect of $0.4 million. Based on the anticipated earnings projections, management has recorded a full valuation allowance for the deferred tax assets associated with this entity.
Income tax expense attributable to income from continuing operations differs from the statutory rates as follows:
As of December 31, 2017, the total amount of unrecognized tax benefit representing uncertainty in certain tax positions was $0.4 million. These uncertain tax positions are based on recognition thresholds and measurement attributes for the financial statement recognition and measurements of a tax position taken or expected to be taken in a tax return. Any prospective adjustments to our accrual for uncertain tax positions will be recorded as an increase or decrease to the provision for income taxes and would impact our effective tax rate. At December 31, 2017, there are no positions for which it is reasonably possible that the total amounts of unrecognized tax benefits would significantly increase or decrease within 12 months. As of December 31, 2017, the amount of accrued interest and penalties was $0.1 million and $0.1 million, respectively. The changes in our gross unrecognized tax benefits during the years ended December 31 are as follows (in thousands):

We lease office space, warehouses, freight distribution centers, terminal yards and equipment under non-cancelable operating lease arrangements. Except where we deliver services within facilities provided by our customers, we lease warehouse and freight distribution centers used in our logistics operations, often in connection with a specific customer program. Where facilities are substantially dedicated to a single customer and our lease is with an independent property owner, we attempt to align lease terms with the expected duration of the underlying customer program. In most cases, we expect our facility leases will be renewed or replaced by other leases in the ordinary course of business. Where possible, we contractually secure the recovery of certain occupancy costs, including rent, during the term of a customer program. Future minimum rental payments pursuant to leases that have an initial or remaining non-cancelable lease term in excess of one year as of December 31, 2017 are as follows (in thousands):
Rental expense for facilities, vehicles and other equipment leased from third parties under operating leases approximated $17.9 million, $20.2 million and $19.2 million for the years ended December 31, 2017, 2016 and 2015. |

| Retirement Plans |
We offer 401(k) defined contribution plans to our employees. The plans are administered by a company controlled by our principal shareholders and include different matching provisions depending on which subsidiary or affiliate is involved. In the plans available to certain employees not subject to collective bargaining agreements, we matched contributions up to $600 annually for each employee who is not considered highly compensated through December 31, 2008, after which some matching contributions were suspended as a response to market conditions at certain subsidiaries. Three other 401(k) plans are provided to employees of specific operations and offer matching contributions that range from zero to $2,080 per participant annually. The total expense for contributions for 401(k) plans, including plans related to collective bargaining agreements, was $0.5 million, $0.5 million and $0.2 million for the years ended December 31, 2017, 2016 and 2015, respectively. In connection with a collective bargaining agreement that covered 12 Canadian employees at December 31, 2017, we are required to make defined contributions into the Canada Wide Industrial Pension Plan. At December 31, 2017 and 2016, the required contributions totaled approximately $41,000 and $31,000, respectively. |

| Stock Based Compensation |
On April 23, 2014, our Board of Directors adopted the 2014 Amended and Restated Stock Incentive Plan, or the Plan. The Plan was approved by our shareholders at the 2014 Annual Meeting and became effective as of the date it was adopted by the Board of Directors. The Plan replaced our 2004 Stock Incentive Plan and carried forward the shares of common stock that remained available for issuance under the 2004 Stock Incentive Plan. The grants may be made in the form of stock options, restricted stock bonuses, restricted stock purchase rights, stock appreciation rights, phantom stock units, restricted stock units or unrestricted common stock. Restricted stock awards currently outstanding under the 2004 Stock Incentive Plan will remain outstanding in accordance with the terms of that plan.
On December 23, 2015, the Company granted 50,000 shares of restricted stock to certain of its employees, including 10,000 shares to its Chief Financial Officer. The restricted stock grants have a grant date fair value of $14.93 per share, based on the closing price of the Company’s stock, of which 25% vested immediately, and an additional 25% will vest in three equal increments on each December 20 in 2016, 2017 and 2018. A grantee’s vesting of restricted stock awards may be accelerated under certain conditions, including retirement. A summary of the status of our non-vested shares as of December 31, 2017, and changes during the year ended December 31, 2017, is presented below:
During the years ended December 31, 2017, 2016 and 2015, the total grant date fair value of vested shares recognized as compensation cost was $414,000, $571,000, and $494,000 respectively. As of December 31, 2017, there was $520,000 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized on a straight-line basis over the remaining vesting period. As a result, the Company expects to recognize stock-based compensation costs of $413,000, $73,000, and $34,000 during 2018, 2019 and 2020, respectively. |

| Commitments And Contingencies Disclosure [Abstract] | |||||
| Commitments and Contingencies |
Our principal commitments relate to long-term real estate leases and payment obligations to equipment vendors. On October 16, 2017, a jury in state court in Cook County, Illinois rendered a verdict of $54.2 million against Universal Am-Can, Ltd. (“UACL”) in the matter of Denton v. UACL, et al. The litigation relates to a vehicular accident that occurred on February 8, 2011 on I-65 in Rensselaer, Indiana. The accident involved a tractor-trailer being driven by an independent owner-operator of UACL. The driver was braking on the expressway in order to avoid another vehicle being driven the wrong way on the interstate. The truck attempted to avoid the oncoming vehicle and the plaintiff’s vehicle and, in so doing, struck the plaintiff’s vehicle. As a result of the accident, the plaintiff sustained non-life threatening injuries. In connection with the verdict, the jury determined that UACL was responsible for the liability associated with the accident. The verdict included $19.2 million in compensatory damages and $35.0 million in punitive damages against UACL. The insurance coverage available for reimbursement of UACL’s damages underlying the verdict is limited to $1.0 million. We believe the facts and the law do not support the jury’s findings of liability against UACL. Post-trial motions have been filed seeking a reduction of the verdict or reversal of the judgment. The Company may further seek to appeal the verdict to the extent the circuit court does not set it aside the judgment as a result of these motions. The Company currently estimates the possible range of financial exposure in the matter, net of insurance coverage, to be between $18.2 and $53.2 million. Based on the Company’s best estimate of the liability at this time, the Company has recorded an accrued liability for this matter of $18.2 million. While we cannot predict with any certainty the outcome of this litigation, its ultimate resolution could be significantly different from our estimate and materially affect our financial condition, results of operations and cash flows. The Company was plaintiff in a lawsuit that was filed on June 11, 2015 against, among others, Dalton Logistics, Inc. (“Dalton”) in the United States District Court for the Southern District of Texas. The Company was seeking approximately $1.9 million in damages from a debtor relating to unpaid freight charges. In response to the filing of the complaint, the shareholders of Dalton filed a counterclaim against the Company alleging that the Company, in connection with certain unrelated negotiations with the defendant, breached an alleged agreement to acquire Dalton. The respective claims proceeded to trial and, on July 21, 2017, a jury returned two separate verdicts: One in favor of Universal for $1.9 million, and a second in favor of the defendant for approximately $5.7 million. On October 30, 2017, the court entered a judgment against Universal for the $5.7 million, but ignored the $1.9 million jury award in favor of Universal. The Company believes this ruling was in error and further believes the jury erred in their findings of any damages against Universal, and therefore, the Company plans to appeal both the ruling and the verdict. The Company currently estimates the possible range of financial exposure in the matter to be between $0 and $5.7 million. Based on the Company’s best estimate of the liability at this time, the Company has recorded an accrued liability for this matter of $1.8 million. While we cannot predict with any certainty the outcome of this litigation, management does not believe the outcome will have a material adverse effect on our business, financial condition, results of operations or cash flows. On February 21, 2018, Ford Motor Company (“Ford”) filed suit against two of the Company’s subsidiaries and two related parties in state court in Oakland County, Michigan (the “Indemnity Action”). The complaint seeks a declaratory judgment that Universal and its co-defendants are required to indemnify Ford for damages sustained by Ford in a wrongful death lawsuit in Clay County, Missouri (the “Underlying Action”). In February 2018, a jury returned a verdict against Ford in the Underlying Action and awarded the decedent’s estate $76 million in damages. Universal believes that, under Michigan law and its agreement with Ford, Universal is not required to indemnify Ford for Ford’s own negligence that led to the jury verdict in the Underlying Action. Additionally, at the time of the incident that is the subject of the Underlying Action, Universal had in place insurance required by Ford providing for up to $3.0 million of coverage from a co-defendant. The Company currently estimates the possible range of financial exposure in the matter, net of insurance coverage, to be between $0 and $73 million. Based on not only its knowledge of the facts associated with the Underlying Action and the Indemnity Action but also the opinions of its outside counsel, Universal has determined that a loss in the Indemnity Action is not probable and no accrual is necessary at this time. While the outcome of the Indemnity Action cannot be predicted with any certainty and management believes the Company will be successful in defending its position, the outcome could have material adverse effect on our business, financial position, results of operations and cash flows. The Company is involved in certain other claims and pending litigation arising from the ordinary conduct of business. We also provide accruals for claims within our self-insured retention amounts. Based on the knowledge of the facts, and in certain cases, opinions of outside counsel, in the Company’s opinion the resolution of these claims and pending litigation will not have a material effect on our financial position, results of operations or cash flows. However, if we experience claims that are not covered by our insurance or that exceed our estimated claim reserve, it could increase the volatility of our earnings and have a materially adverse effect on our financial condition, results of operations or cash flows.
At December 31, 2017, approximately 19% of our employees in the United States, Canada and Colombia, and 95% of our employees in Mexico are subject to collective bargaining agreements that are renegotiated periodically. None of the employees in the United States, Canada and Colombia are subject to contracts that expire in 2018. The contract for our Mexican employees expiring in 2018 is currently being negotiated. |

| Earnings Per Share |
Basic earnings per common share amounts are based on the weighted average number of common shares outstanding, excluding outstanding non-vested restricted stock. Diluted earnings per common share include dilutive common stock equivalents determined by the treasury stock method. For the years ended December 31, 2017, 2016 and 2015, there were 2,922, zero and 2,273 weighted average non-vested shares of restricted stock, respectively, included in the denominator for the calculation of diluted earnings per share. For the years ended December 31, 2017, 2016 and 2015, 2,500, 45,000 and 30,725 shares of non-vested restricted stock, respectively, were excluded from the calculation of diluted earnings per share because such shares were anti-dilutive. |

| Segment Reporting |
We report our financial results in two reportable segments, the transportation segment and the logistics segment, based on the nature of the underlying customer commitment and the types of investments required to support these commitments. This presentation reflects the manner in which management evaluates our operating segments, including an evaluation of economic characteristics and applicable aggregation criteria. Operations aggregated in our transportation segment are associated with individual freight shipments coordinated by our agents, company-managed terminals and specialized services operations. In contrast, operations aggregated in our logistics segment deliver value-added services or transportation services to specific customers on a dedicated basis, generally pursuant to contract terms of one year or longer. Other non-reportable operating segments are comprised of the Company’s subsidiaries that provide support services to other subsidiaries and to owner-operators, including shop maintenance and equipment leasing. The following tables summarize information about our reportable segments as of and for the fiscal years ended December 31, 2017, 2016 and 2015 (in thousands):
We provide a portfolio of transportation and logistics services to a wide range of customers throughout the United States and in Mexico, Canada and Colombia. Revenues attributed to geographic areas are as follows (in thousands):

| Accounting Changes And Error Corrections [Abstract] | |||||
| Recent Accounting Pronouncements |
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. In applying the new guidance, an entity will (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the contract’s performance obligations; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. For our transportation services businesses, which include truckload, brokerage, intermodal and dedicated services, the adoption of the standard will change the timing of revenue recognition from at delivery to over-time as the performance obligations on the in-transit services are completed. For our value-added service businesses, the adoption of the standard will not change the timing of revenue recognition. On January 1, 2018, the Company adopted ASU 2014-09 using the modified retrospective transition method with a cumulative adjustment to retained earnings. Due to the Company’s short in-transit period for transportation services, the impact did not have a significant impact on its results of operations, financial position or cash flows. The standard also requires additional disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company is finalizing its evaluation of the impact of the required disclosures that will be effective in the first quarter 2018 and expects the disclosures to be enhanced. In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. Among other things, the ASU requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. The amendments are to be applied by means of a cumulative-effect adjustment to the balance sheet and are effective for interim and annual periods beginning after December 15, 2017. The Company adopted this new standard effective January 1, 2018 using the modified retrospective method with a cumulative adjustment to retained earnings of approximately $3.8 million. In February 2016, the FASB issued ASU 2016-02, Leases. The objective of the new standard is to establish principles for lessees and lessors to report information about the amount, timing, and uncertainty of cash flows arising from a lease. The ASU will require a lessee to recognize the assets and liabilities that arise from leases, including operating leases. Under the new requirements, a lessee will recognize in the statement of financial position a liability to make lease payments (the lease liability) and the right-of-use asset representing the right to the underlying asset for the lease term. For leases with a term of 12 months or less, the lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. This update is effective for annual and interim periods beginning after December 15, 2018, which will require us to adopt these provisions in the first quarter of 2019 using a modified retrospective approach. Early adoption is permitted, although we do not plan to adopt early. We are currently evaluating the effects ASU 2016-02 will have on our consolidated financial statements and related disclosures. We currently disclose approximately $71.8 million in operating lease obligations in Note 9, “Leases”. We will evaluate those contracts as well as other existing arrangements to determine if they qualify for lease accounting under the new standard. Upon adoption, we would expect the amount recognized for the right-of-use assets and lease liabilities to be material to the consolidated financial statements.
In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This update simplifies the accounting for goodwill impairments by eliminating step 2 from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value and impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The ASU is effective for annual and any interim impairment tests for periods beginning after December 15, 2019. Early adoption is permitted for interim and annual goodwill impairment tests performed after January 1, 2017. We early adopted this ASU for our annual impairment test performed in the third quarter 2017. There was no impact resulting from this adoption on our consolidated financial statements.
In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income, which amends existing guidance for reporting comprehensive income to reflect changes resulting from the 2017 Tax Act. The amendment provides the option to reclassify stranded tax effects resulting from the 2017 Tax Act and within accumulated other comprehensive income (AOCI) to retained earnings. New disclosures will be required upon adoption, including the accounting policy for releasing income tax effects from AOCI, whether reclassification of stranded income tax effects is elected, and information about other income tax effect reclassifications. The amendment will become effective for us on January 1, 2019, though early adoption is permitted. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures |

Apa Holdings owns and leases real property and improvements, including a 28-acre terminal that serves as Fore’s corporate headquarters and its secured trailer and container storage facility for 1,100 units. The total cash purchase price was $34.9 million, subject to customary post-closing adjustments. To fund the acquisition, the Company used available cash and borrowed approximately $31.3 million using its margin credit facility, revolving credit facility and secured real estate financing. The Company is in the process of finalizing the purchase accounting for this transaction. On February 22, 2018, our Board of Directors declared a quarterly cash dividend of $0.07 per share of common stock, which is payable to shareholders of record at the close of business on March 5, 2018 and is expected to be paid on March 15, 2018. Declaration of future cash dividends is subject to final determination by the Board of Directors each quarter after its review of our financial condition, results of operations, capital requirements, any legal or contractual restrictions on the payment of dividends and other factors the Board of Directors deems relevant. |

| Accounting Policies [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Basis of Presentation |
The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions relating to these entities have been eliminated. Our fiscal year consists of four quarters, each with thirteen weeks. Certain immaterial reclassifications have been made to the prior consolidated financial statements in order for them to conform to the December 31, 2017 presentation, including the reclassification of revenue categories to reflect Universal’s service offering. These reclassifications had no effect on reported consolidated net income, comprehensive income, earnings per common share, cash flows, total assets, or stockholders' equity as previously reported. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Use of Estimates |
The preparation of the consolidated financial statements requires management of the Company to make a number of estimates and assumptions related to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Significant items subject to such estimates and assumptions include the fair value of assets and liabilities acquired in business combinations; carrying amounts of property and equipment and intangible assets; marketable securities; valuation allowances for receivables; and liabilities related to insurance and claim costs. Actual results could differ from those estimates. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Cash and Cash Equivalents |
We consider all highly liquid investments, purchased with a maturity of three months or less, to be cash equivalents. Accounts at banks with an aggregate excess of the amount of checks issued over cash balances are included as accounts payable in current liabilities in the consolidated balance sheets, and changes in such accounts are reported as cash flows from operating activities in the consolidated statements of cash flows. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Marketable Securities |
At December 31, 2017 and 2016, marketable securities, all of which are available-for-sale, consist of common and preferred stocks. Marketable securities are carried at fair value, with unrealized gains and losses, net of related income taxes, reported as accumulated other comprehensive income (loss), except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net income and are included in other non-operating income (expense), at which time the average cost basis of these securities are adjusted to fair value. Fair values are based on quoted market prices at the reporting date. Interest and dividends on available-for-sale securities are included in other non-operating income (expense). During the years ended December 31, 2017, 2016 and 2015, we received proceeds of $1.3 million, $0.9 million and $0.4 million from the sale of marketable securities with a combined cost of $0.3 million, $0.5 million and $0.1 million resulting in a realized gain of $0.9 million, $0.4 million and $0.3 million, respectively. We plan to adopt Accounting Standards Update (“ASU”) 2016-01 effective as of January 1, 2018. See Note 17 “Recent Accounting Pronouncements” for further information regarding the adoption.
The cost, gross unrealized holding gains, gross unrealized holding losses, and fair value of available-for-sale securities by type were as follows (in thousands):
Included in equity securities at December 31, 2017 were securities with a book basis of $3.0 million and a cumulative loss position of $0.5 million, the impairment of which we consider to be temporary. Equity securities at December 31, 2016 included securities with a book basis of $3.5 million and temporary impairments of $0.6 million. We consider several factors in determining as to whether declines in value are judged to be temporary or other-than-temporary, including the severity and duration of the decline, the financial condition and near-term prospects of the specific issuers and the industries in which they operate, and our intent and ability to hold these securities. We may incur future impairment charges if declines in market values continue and/or worsen and impairments are no longer considered temporary. The fair value and gross unrealized holding losses of our marketable securities that are not deemed to be other-than-temporarily impaired aggregated by type and length of time they have been in a continuous unrealized loss position were as follows (in thousands):
At December 31, 2017, our portfolio of equity securities in a continuous loss position, the impairment of which we consider to be temporary, consists primarily of common stocks in the oil and gas, banking, transportation, communication, and pharmaceutical industries. The fair value and unrealized losses are distributed in 20 publicly traded companies, with no single industry or company representing a material or concentrated unrealized loss. We have evaluated the near-term prospects of the various industries, as well as the specific issuers within our portfolio, in relation to the severity and duration of the impairments, and based on that evaluation, and our ability and intent to hold these investments for a reasonable period of time to allow for a recovery of fair value, we do not consider these investments to be other-than-temporarily impaired at December 31, 2017. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Accounts Receivable |
Accounts receivable are recorded at the net invoiced amount, net of an allowance for doubtful accounts, and do not bear interest. They include unbilled amounts for services rendered in the respective period but not yet billed to the customer until a future date, which typically occurs within one month. In order to reflect customer receivables at their estimated net realizable value, we record charges against revenue based upon current information. These charges generally arise from rate changes, errors, and revenue adjustments that may arise from contract disputes or differences in calculation methods employed by the customer. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on historical write-off experience and the aging of our outstanding accounts receivable. Balances are considered past due based on invoiced terms. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. We do not have any off‑balance‑sheet credit exposure related to our customers. Accounts receivable from affiliates are shown separately and include trade receivables from the sale of services to affiliates. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Inventories |
Included in prepaid expenses and other is inventory used in a portion of our value-added service operations. Inventories are stated net realizable value. Cost is determined using the first-in, first-out method. Provisions for excess and obsolete inventories are based on our assessment of excess and obsolete inventory on a product-by-product basis. At December 31, inventory consists of the following (in thousands):
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Property and Equipment |
Property and equipment, including leasehold improvements, are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:
The amounts recorded for depreciation expense were $41.0 million, $29.2 million, and $25.8 million for the years ended December 31, 2017, 2016 and 2015, respectively. Tire repairs, replacement tires, replacement batteries, consumable tools used in our logistics services, and routine repairs and maintenance on vehicles are expensed as incurred. Parts and fuel inventories are included in prepaid expenses and other. We capitalize certain costs associated with vehicle repairs and maintenance that materially extend the life or increase the value of the vehicle or pool of vehicles. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Intangible Assets |
Intangible assets subject to amortization consist of customer contracts and agent and customer relationships that have been acquired in business combinations. These assets are amortized either over the period of economic benefit or on a straight-line basis over the estimated useful lives of the related intangible asset. The estimated useful lives of these intangible assets range from three to nineteen years. The useful lives of acquired trademarks are indefinite and, therefore, not subject to amortization. Our identifiable intangible assets as of December 31, 2017 and 2016 are as follows (in thousands):
Estimated amortization expense by year is as follows (in thousands):
The amounts recorded for amortization expense were $6.0 million, $7.5 million, and $9.2 million for the years ended December 31, 2017, 2016 and 2015, respectively. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Goodwill |
Goodwill represents the excess purchase price over the fair value of assets acquired in connection with the Company’s acquisitions. Under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification, or ASC, Topic 350 “Intangibles – Goodwill and Other”, we are required to test goodwill for impairment annually (in our third fiscal quarter) or more frequently, whenever events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit with goodwill below its carrying amount. We have the option to first assess qualitative factors such as current performance and overall economic conditions to determine whether or not it is necessary to perform a quantitative goodwill impairment test. If we choose that option, then we would not be required to perform a quantitative goodwill impairment test unless we determine that, based on a qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying value. If we determine that it is more likely than not, or if we choose not to perform a qualitative assessment, we then proceed with the quantitative assessment. Under the quantitative test, if the fair value of a reporting unit exceeds its carrying amount, then goodwill of the reporting unit is considered to not be impaired. If the carrying amount of the reporting unit exceeds its fair value, then an impairment loss is recognized in an amount equal to the excess, up to the value of the goodwill. During the third quarter of 2017, we completed our goodwill impairment testing by performing a quantitative assessment. Based on the results of this test, no impairment loss was recognized. At both December 31, 2017 and 2016, the carrying amount of goodwill was $74.5 million, of which $18.2 million was recorded in our transportation segment and $56.3 million in our logistics segment.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Long-Lived Assets |
Long-lived assets, other than goodwill and indefinite lived intangibles such as property and equipment and purchased intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or group may not be recoverable. If circumstances require a long-lived asset to be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by a long-lived asset or group to its carrying value. If the carrying value of the long-lived asset or group is deemed to not be recoverable on an undiscounted cash flow basis, an impairment charge is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market prices and independent third-party appraisals. Changes in management’s judgment relating to salvage values and/ or estimated useful lives could result in greater or lesser annual depreciation expense or impairment charges in the future. Indefinite lived intangibles are tested for impairment annually by comparing the carrying value of the assets to their fair value. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Contingent Consideration |
Contingent consideration arrangements granted in connection with a business combination are evaluated to determine whether contingent consideration is, in substance, additional purchase price of an acquired enterprise or compensation for services, use of property or profit sharing. Additional purchase price is added to the fair value of consideration transferred in the business combination and compensation is included in operating expenses in the period it is incurred. Contingent consideration related to additional purchase price is measured to fair value at each reporting date until the contingency is resolved. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value of Financial Instruments |
For cash equivalents, accounts receivables, accounts payable, and accrued expenses, the carrying amounts are reasonable estimates of fair value as the assets are readily redeemable or short‑term in nature and the liabilities are short-term in nature. Marketable securities, consisting of equity securities, are carried at fair market value as determined by quoted market prices. Our revolving credit and term loan agreements consist of variable rate borrowings. The carrying value of these borrowings approximates fair value because the applicable interest rates are adjusted frequently based on short-term market rates. For our equipment promissory notes, the fair values are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. See Note 6 “Fair Value Measurement and Disclosures” for further information. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Deferred Compensation |
Deferred compensation relates to our bonus plans. Annual bonuses may be awarded to certain operating, sales and management personnel based on overall Company performance and achievement of specific employee or departmental objectives. Such bonuses are typically paid in annual installments over a five-year period. All bonus amounts earned by and due to employees in the current year are included in accrued expenses and other current liabilities. Those that are payable in subsequent years are included in other long-term liabilities. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Closing Costs |
Our customers may discontinue or alter their business activity in a location earlier than anticipated, prompting us to exit a customer-dedicated facility. We recognize exit costs associated with operations that close or are identified for closure as an accrued liability in the Consolidated Balance Sheets. Such charges include lease termination costs, employee termination charges, asset impairment charges, and other exit-related costs associated with a plan approved by management. If we close an operating facility before its lease expires, costs to terminate a lease are recognized when an early termination provision is exercised, or we record a liability for non-cancellable lease obligations based on the fair value of remaining lease payments, reduced by any existing or prospective sublease rentals. Employee termination costs are recognized in the period that the closure is communicated to affected employees. The recognition of exit and disposal charges requires us to make certain assumptions and estimates as to the amount and timing of such charges. Subsequently, adjustments are made for changes in estimates in the period in which the change becomes known. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue and Related Expenses |
We are the primary obligor when rendering truckload, brokerage, intermodal, dedicated and value-added services, and assume the corresponding credit risk with customers. We have discretion in setting sales prices and, as a result, our earnings may vary. In addition, we have discretion to choose and negotiate terms with our multiple suppliers for the services ordered by our customers. This includes owner-operators with whom we contract to deliver our transportation services. As such, revenue and the related purchased transportation and commissions are recognized on a gross basis when persuasive evidence of an arrangement exists, delivery has occurred at the receiver’s location or for service arrangements after the related services have been rendered, the revenue and related expenses are fixed or determinable and collectability is reasonably assured. Fuel surcharges, where separately identifiable, of $59.5 million, $50.9 million and $75.7 million for the years ended December 31, 2017, 2016 and 2015, respectively, are included in operating revenues. Revenues and associated costs for the sales of axles and machined components are recognized when title has passed and the risks and rewards of ownership are transferred, which is at the time of shipment. Our customer contracts could involve multiple revenue-generating activities performed for the same customer. When several contracts are entered into with the same customer in a short period of time, we evaluate whether these contracts should be considered as a single, multiple element contract for revenue recognition purposes. Criteria we consider that may result in the aggregation of contracts include whether such contracts are actually entered into within a short period of time, whether services in multiple contracts are interrelated, or if the negotiation and terms of one contract show or include consideration for another contract or contracts. Our current contracts have not been required to be aggregated, as they are negotiated independently on a standalone basis. Our customers typically choose their vendor and award business at the conclusion of a competitive bidding process for each service. As a result, although we evaluate customer purchase orders and agreements for multiple elements and aggregation of individual contracts into a multiple element arrangement, our current contracts do not meet the criteria required for multiple element contract accounting. We adopted Accounting Standards Update (“ASU”) 2014-09 effective as of January 1, 2018, as further described in Note 17 “Recent Accounting Pronouncements”. The adoption of this standard will change the timing of revenue recognition for our transportation services businesses, which include truckload, brokerage, intermodal and dedicated services, from at delivery to over-time as the performance obligations on the in-transit services are completed. For our value-added service businesses, the adoption of the standard will not change the timing of revenue recognition. |

| Insurance & Claims | (1)Summary of Significant Accounting Policies—continued
Insurance and claims expense represents charges for premiums and the accruals made for claims within our self-insured retention amounts. The accruals are primarily related to auto liability, general liability, cargo and equipment damage, and service failure claims. A liability is recognized for the estimated cost of all self-insured claims including an estimate of incurred but not reported claims based on historical experience and for claims expected to exceed our policy limits. We may also make accruals for personal injury and property damage to third parties, and workers’ compensation claims if a claim exceeds our insurance coverage. Such accruals are based upon individual cases and estimates of ultimate losses, incurred but not reported losses, and losses arising from known claims ultimately settling in excess of insurance coverage using loss development factors based upon industry data and past experience. Since the reported accrual is an estimate, the ultimate liability may be materially different from the amount recorded. If adjustments to previously established accruals are required, such amounts are included in operating expenses in the current period. We maintain insurance with licensed insurance carriers. Legal expenses related to auto liability claims are covered under our insurance policy. We are responsible for all other legal expenses related to claims. In brokerage arrangements, our exposure to liability associated with accidents incurred by other third-party carriers, who haul freight on our behalf, is reduced by various factors including the extent to which the third party providers maintain their own insurance coverage. Our insurance expense varies primarily based upon the frequency and severity of our accident experience, insurance rates, coverage limits, and self-insured retention amounts. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Stock Based Compensation |
We record compensation expense for the grant of stock based awards. Compensation expense is measured at the grant date, based on the calculated fair value of the award, and recognized as an expense over the requisite service period (generally the vesting period of the grant). See Note 12 “Stock Based Compensation” for further information. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Taxes |
Deferred income taxes are provided for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. See Note 8 “Income Taxes” for further information on the impact of the Tax Cuts and Jobs Act (the “Tax Cuts and Jobs Act”) signed into law on December 22, 2017. We are no longer subject to U.S. federal income tax examinations by tax authorities for years before 2013. In addition, we file income tax returns in various state, local and foreign jurisdictions. Historically, we have been responsible for filing separate state, local and foreign income tax returns for our self and our subsidiaries. We are no longer subject to state or foreign jurisdiction income tax examinations for years before 2012 and 2011, respectively. We recognize the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We recognize interest related to unrecognized tax benefits in income tax expense and penalties in other operating expenses. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Foreign Currency Translation |
The financial statements of the Company’s subsidiaries operating in Mexico, Canada and Colombia are prepared to conform to U.S. GAAP and translated into U.S. Dollars by applying a current exchange rate. The local currency has been determined to be the functional currency. Items appearing in the Consolidated Statements of Income are translated using average exchange rates during each period. Assets and liabilities of international operations are translated at period-end exchange rates. Translation gains and losses are reported in accumulated other comprehensive income (loss) as a component of shareholders’ equity. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Concentrations of Credit Risk |
We report our financial results in two reportable segments, the transportation segment and the logistics segment, based on the nature of the underlying customer commitment and the types of investments required to support these commitments. This presentation reflects the manner in which management evaluates our operating segments, including an evaluation of economic characteristics and applicable aggregation criteria. Operations aggregated in our transportation segment are associated with individual freight shipments coordinated by our agents, company-managed terminals and specialized services operations. In contrast, operations aggregated in our logistics segment deliver value-added services or transportation services to specific customers on a dedicated basis, generally pursuant to contract terms of one year or longer. Other non-reportable operating segments are comprised of the Company’s subsidiaries that provide support services to other subsidiaries and to owner-operators, including shop maintenance and equipment leasing.
Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of cash and cash equivalents, marketable securities and accounts receivable. We maintain our cash and cash equivalents and marketable securities with high quality financial institutions. We perform ongoing credit evaluations of our customers and generally do not require collateral. Our customers are generally concentrated in the automotive, wind energy, building materials, machinery and metals industries. During the fiscal years ended December 31, 2017, 2016 and 2015, aggregate sales in the automotive industry totaled 40%, 43% and 37% of revenue, respectively. In 2017, 2016 and 2015, General Motors accounted for approximately 16%, 18% and 11% of our total operating revenues, respectively. In 2017, sales to our top 10 customers, including General Motors, totaled 40%. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. In applying the new guidance, an entity will (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the contract’s performance obligations; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. For our transportation services businesses, which include truckload, brokerage, intermodal and dedicated services, the adoption of the standard will change the timing of revenue recognition from at delivery to over-time as the performance obligations on the in-transit services are completed. For our value-added service businesses, the adoption of the standard will not change the timing of revenue recognition. On January 1, 2018, the Company adopted ASU 2014-09 using the modified retrospective transition method with a cumulative adjustment to retained earnings. Due to the Company’s short in-transit period for transportation services, the impact did not have a significant impact on its results of operations, financial position or cash flows. The standard also requires additional disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company is finalizing its evaluation of the impact of the required disclosures that will be effective in the first quarter 2018 and expects the disclosures to be enhanced. In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. Among other things, the ASU requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. The amendments are to be applied by means of a cumulative-effect adjustment to the balance sheet and are effective for interim and annual periods beginning after December 15, 2017. The Company adopted this new standard effective January 1, 2018 using the modified retrospective method with a cumulative adjustment to retained earnings of approximately $3.8 million. In February 2016, the FASB issued ASU 2016-02, Leases. The objective of the new standard is to establish principles for lessees and lessors to report information about the amount, timing, and uncertainty of cash flows arising from a lease. The ASU will require a lessee to recognize the assets and liabilities that arise from leases, including operating leases. Under the new requirements, a lessee will recognize in the statement of financial position a liability to make lease payments (the lease liability) and the right-of-use asset representing the right to the underlying asset for the lease term. For leases with a term of 12 months or less, the lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. This update is effective for annual and interim periods beginning after December 15, 2018, which will require us to adopt these provisions in the first quarter of 2019 using a modified retrospective approach. Early adoption is permitted, although we do not plan to adopt early. We are currently evaluating the effects ASU 2016-02 will have on our consolidated financial statements and related disclosures. We currently disclose approximately $71.8 million in operating lease obligations in Note 9, “Leases”. We will evaluate those contracts as well as other existing arrangements to determine if they qualify for lease accounting under the new standard. Upon adoption, we would expect the amount recognized for the right-of-use assets and lease liabilities to be material to the consolidated financial statements. Recent Accounting Pronouncements - continued In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This update simplifies the accounting for goodwill impairments by eliminating step 2 from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value and impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. The ASU is effective for annual and any interim impairment tests for periods beginning after December 15, 2019. Early adoption is permitted for interim and annual goodwill impairment tests performed after January 1, 2017. We early adopted this ASU for our annual impairment test performed in the third quarter 2017. There was no impact resulting from this adoption on our consolidated financial statements.
In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income, which amends existing guidance for reporting comprehensive income to reflect changes resulting from the 2017 Tax Act. The amendment provides the option to reclassify stranded tax effects resulting from the 2017 Tax Act and within accumulated other comprehensive income (AOCI) to retained earnings. New disclosures will be required upon adoption, including the accounting policy for releasing income tax effects from AOCI, whether reclassification of stranded income tax effects is elected, and information about other income tax effect reclassifications. The amendment will become effective for us on January 1, 2019, though early adoption is permitted. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures |
