Basis of Consolidation. The consolidated financial statements reflect the accounts of the Company and its wholly-owned and majority-owned subsidiaries. All significant intercompany profits, transactions, and balances have been eliminated in consolidation.

Use of Estimates. The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that directly affect the amounts reported in its consolidated financial statements and accompanying notes. Actual results could differ from these estimates.

Accounts Receivable. Accounts receivable are shown net of expected losses and primarily include trade receivables. The Company records expected losses for customers based upon a variety of factors including the Company’s historical collection experience, the length of time the account has been outstanding and the financial condition of the customer. If the circumstances related to specific customers were to change, the Company’s estimates of expected losses with respect to the collectability of the related accounts could be further adjusted. The Company’s policy is to write-off receivables when they are determined to be uncollectible. Expected losses are charged to Selling and General and administrative expenses in the Consolidated Statements of Operations. The following table presents the changes in expected losses (in thousands):


	December 31,
	2021		2020
Chassis converter pool agreements	$	18,185	$	17,767
Income tax receivables	10,386		18,073
Insurance premiums & maintenance/subscription agreements	3,290		4,384
Assets held for sale	350		1,897
Commodity swap contracts	7,963		13,750
All other	3,621		7,165
	$	43,795	$	63,036

Chassis converter pool agreements represent chassis transferred to the Company on a restricted basis by the manufacturer, who retains the sole authority to authorize commencement of work on the chassis and to make certain other decisions with respect to the chassis including the terms and pricing of sales to the manufacturer’s dealers. Assets held for sale are related to property, plant, and equipment assets that are unused, are actively being marketed for sale, and for which sale is expected within the next 12 months. As further described in Note 10, commodity swap contracts relate to our hedging activities (that are in an asset position) to mitigate the risks associated with fluctuations in commodity prices. Insurance premiums and maintenance/subscription agreements are charged to expense over the contractual life, which is generally one year or less. Other items primarily consist of contract assets related to contracts for which the Company recognizes revenue on an over time basis and investments held by the Company’s captive insurance subsidiary. As of December 31, 2021 and 2020, there was no restricted cash included in prepaid expenses and other current assets.

Property, Plant and Equipment. Property, plant and equipment are recorded at cost, net of accumulated depreciation. Maintenance and repairs are charged to expense as incurred, while expenditures that extend the useful life of an asset are capitalized. Depreciation is recorded using the straight-line method over the estimated useful lives of the depreciable assets. The estimated useful lives are up to 33 years for buildings and building improvements and range from three to ten years for machinery and equipment.

Goodwill. Goodwill represents the excess purchase price over fair value of the net assets acquired. The Company determines its reporting units at the individual operating segment level, or one level below, when there is discrete financial information available that is regularly reviewed by segment management for evaluating operating results. The Company reviews goodwill for impairment, at the reporting unit level, annually on October 1 and whenever events or changes in circumstances indicate its carrying value may not be recoverable. In accordance with ASC 350, Intangibles - Goodwill and Other, goodwill is reviewed for impairment utilizing either a qualitative assessment or a quantitative process.

The Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity has an unconditional option to bypass the qualitative assessment in any period and proceed directly to performing the quantitative impairment test, which is the option the Company has historically chosen.

For reporting units in which the Company performs the quantitative analysis, the Company compares the carrying value, including goodwill, of each reporting unit with its estimated fair value. If the fair value of the reporting unit exceeds its carrying value, the goodwill is not considered impaired. If the carrying value is greater than the fair value, the difference is recognized as an impairment loss charged to the reporting unit. After an impairment loss is recognized, the adjusted carrying amount of goodwill shall be its new accounting basis.

As of December 31, 2021, goodwill allocated to the TS and P&S segments was approximately $120.5 million and $67.9 million, respectively. Because of the recency and lack of changes with respect to market conditions and data assumptions used in the quantitative assessment performed in connection with the segment realignment discussed in more detail in Note 5, during the fourth quarter of 2021 the Company completed its annual goodwill impairment test using a qualitative assessment. As part of the qualitative analysis, the Company considered many factors including, but not limited to, general economic conditions, industry and market conditions, financial performance and key business drivers, long-term operating plans, and potential changes to significant assumptions used in the fair value analysis for each reporting unit (performed in connection with the segment realignment).

Except for the impairment charges during the first quarter of 2020, based on all assessments performed in each of the last three years the Company believed it was more likely than not that the fair value of its reporting units were greater than their carrying amount and no additional impairment of goodwill was recognized.

Long-Lived Assets. Long-lived assets, consisting primarily of intangible assets and property, plant and equipment, are reviewed for impairment whenever facts and circumstances indicate that the carrying amount may not be recoverable. Specifically, this process involves comparing an asset’s carrying value to the estimated undiscounted future cash flows the asset is expected to generate over its remaining life. If this process were to result in the conclusion that the carrying value of a long-lived asset would not be recoverable, a write-down of the asset to fair value would be recorded through a charge to operations. Fair value is determined based upon discounted cash flows or appraisals as appropriate.

As further described in Note 5, in connection with the Company’s rebranding initiative the Company recorded non-cash impairment charges of approximately $28.3 million during the fourth quarter of 2021 related to trade name and trademark intangible assets due to the significant reduction in the related useful lives of these assets. Net intangible assets of approximately $1.3 million were written-off during the second quarter of 2021 in connection with the Extract® Technology divestiture. In addition, net intangible assets of approximately $1.1 million were written-off during the fourth quarter of 2020 in connection with the Beall® divestiture.

Other Assets. The Company capitalizes the cost of computer software developed or obtained for internal use. Capitalized software is amortized using the straight-line method over three to seven years. As of December 31, 2021 and 2020, the Company had software costs, net of amortization, of $4.2 million and $6.1 million, respectively. Amortization expense for 2021, 2020, and 2019 was $1.7 million, $2.0 million, and $1.7 million, respectively.

Warranties. The Company offers a limited warranty for its products with a coverage period that ranges between one and five years, except that the coverage period for DuraPlate® trailer panels is ten years. The Company passes through component manufacturers’ warranties to our customers. The Company’s policy is to accrue the estimated cost of warranty coverage at the time of the sale.

Self Insured Liabilities. The Company is self-insured up to specified limits for medical and workers’ compensation coverage. The self-insurance reserves have been recorded to reflect the undiscounted estimated liabilities, including claims incurred but not reported, as well as catastrophic claims as appropriate.

Income Taxes. The Company determines its provision or benefit for income taxes under the asset and liability method. The asset and liability method measures the expected tax impact at current enacted rates of future taxable income or deductions resulting from differences in the tax and financial reporting basis of assets and liabilities reflected in the Consolidated Balance Sheets. Future tax benefits of tax losses and credit carryforwards are recognized as deferred tax assets. Deferred tax assets are reduced by a valuation allowance to the extent management determines that it is more-likely-than-not the Company would not realize the value of these assets.

Used Trailer Trade Commitments. The Company may accept trade-in of used trailers when a customer enters into a contract to purchase a new trailer. However, in the contracts for the sale of the new trailers, there is no commitment to repurchase that trailer or a similar trailer in the future. The Company had no outstanding trade commitments as of December 31, 2021 and December 31, 2020. On occasion, the amount of the trade allowance provided for in the used trailer commitments, or cost, may exceed the net realizable value of the underlying used trailer. In these instances, the Company’s policy is to recognize the loss related to these commitments at the time the new trailer revenue is recognized. Net realizable value of used trailers is measured considering market sales data for comparable types of trailers.

Concentration of Credit Risk. Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash, cash equivalents, and customer receivables. We place our cash and cash equivalents with high quality financial institutions. Generally, we do not require collateral or other security to support customer receivables.

Research and Development. Research and development expenses are charged to Cost of sales and General and administrative expenses in the Consolidated Statements of Operations as incurred and were $13.6 million, $21.9 million, and $19.5 million in 2021, 2020, and 2019, respectively.
