Annual Report for Fiscal Year Ending 12-31, 2024 (Form 10-K)

Management's Discussion and Analysis of Financial Condition and Results of Operations.

Business Overview

The Company's administrative headquarters are in Tontitown, Arkansas. From this location we manage operations conducted through our wholly-owned subsidiaries based in various locations around the United States, Mexico, and Canada. The operations of these subsidiaries can generally be classified into either truckload services or brokerage and logistics services. This designation is based primarily on the ownership of the asset that performed the freight transportation service. Truckload services are performed by Company divisions that generally utilize Company- owned trucks, long-term contractors, or single-trip contractors to transport loads of freight for customers, while brokerage and logistics services coordinate or facilitate the transport of loads of freight for customers and generally involve the utilization of single-trip contractors. Both our truckload operations and our brokerage and logistics operations have similar economic characteristics and are impacted by virtually the same economic factors as discussed elsewhere in this Report. Based on the Company's segment identification, interpretation of the aggregation criteria outlined in ASC 280-10-50-11, and the similar qualitative and quantitative economic characteristics of the Company's operating segments, the operations of the Company are aggregated into a single motor carrier segment.

For both operations, substantially all of our revenue is generated by transporting freight for customers and is predominantly affected by the rates per mile received from our customers, equipment utilization, and our percentage of non-compensated miles. These aspects of our business are carefully managed and efforts are continuously underway to achieve favorable results. Truckload services revenues, excluding fuel surcharges, represented 67.1%, 65.3% and 66.1% of total revenues, excluding fuel surcharges for the twelve months ended December 31, 2024, 2023 and 2022, respectively.

The main factors that impact our profitability on the expense side are costs incurred in transporting freight for our customers. Currently, our most challenging costs include fuel, driver recruitment, training, wage and benefit costs, independent broker costs (which we record as purchased transportation), insurance and claims, maintenance, and capital equipment costs.

The Company's chief operating decision maker, the Chief Executive Officer, utilizes the metrics of net income and operating ratio to evaluate company performance and in competitive analysis when comparing to competing companies. The accounting policies of the motor carrier segment are the same as those described in the summary of accounting policies found in this report. For purposes of this report, net income reflects the profitability of our operations by calculating the total earnings after deducting operating expenses, interest expense, income taxes and any other applicable costs from total revenue. The measure of net income is reported on the consolidated statement of operations as consolidated net (loss) income. Operating ratio is the measure of our efficiency in managing operating expenses relative to revenue generation and is calculated as total operating expenses as a percentage of total operating revenue.

In discussing our results of operations we use revenue, before fuel surcharge (and operating supplies and expense, net of fuel surcharge), because management believes that eliminating the impact of this sometimes volatile source of revenue allows a more consistent basis for comparing our results of operations from period to period. During 2024, 2023 and 2022, approximately $85.6 million, $104.7 million, and $128.1 million, respectively, of the Company's total revenue was generated from fuel surcharges. We also discuss certain changes in our expenses as a percentage of revenue, before fuel surcharge, rather than absolute dollar changes. We do this because we believe the high variable cost nature of certain expenses makes a comparison of changes in expenses as a percentage of revenue more meaningful than absolute dollar changes.

Results of Operations - Truckload Services

The following table sets forth, for truckload services, the percentage relationship of expense items to operating revenues, before fuel surcharges, for the periods indicated. Operating supplies and expenses are shown net of fuel surcharges.

2024 Compared to 2023

For the year ended December 31, 2024, truckload services revenue, before fuel surcharges, decreased 8.4% to $422.0 million as compared to $460.9 million for the year ended December 31, 2023. The decrease relates primarily to a 5.7% decrease in total miles travelled from 189.5 million during the year ended December 31, 2023 to 178.6 million for the year ended December 31, 2024 and to a 3.2% decrease in our rate per mile, from $2.17 for the year ended December 31, 2023 to $2.10 for the year ended December 31, 2024. The reduction in total miles was primarily driven by a 3.1% reduction in the average number of trucks operated combined with a 3.5% reduction in average miles driven by each truck during the year ended December 31, 2024 compared to the year ended December 31, 2023. The reduction in truck count and miles resulted from a less favorable freight market year over year, characterized by an oversupply of available trucks in the market compared to available freight.

Salaries, wages and benefits increased from 37.8% of revenues, before fuel surcharges, during 2023 to 38.9% of revenues, before fuel surcharges, during 2024. The percentage-based increase relates primarily to the interaction of a decrease in operating revenues with the fixed-cost nature of employing human capital.

Rent and purchased transportation increased from 23.5% of revenues, before fuel surcharges, during 2023 to 26.1% of revenues, before fuel surcharges, during 2024. The increase was primarily due to a year-over-year increase in the percentage of miles driven by third-party owner-operators as opposed to company-employed drivers and to a lesser extent increased rates paid to third-party carriers for the year ended December 31, 2024 compared to the year ended December 31, 2023.

Depreciation increased from 13.8% of revenues, before fuel surcharges, during 2023 to 23.3% of revenues, before fuel surcharges, during 2024. The increase is primarily attributed to management's change in accounting estimates related to the salvage values and useful lives of revenue equipment during the year ended December 31, 2024. During 2024, the Company conducted a review of its revenue equipment and determined that changes in market conditions and expected asset usage warranted a revision to the estimated useful lives and salvage values of certain equipment. As a result, during the year ended December 31, 2024, the Company reduced the estimated useful lives of its trailer equipment and lowered the estimated salvage values of revenue equipment to better reflect their expected residual values at the end of their service periods. This change in accounting estimates increased depreciation expense by approximately $24.7 million and increased basic and diluted loss per share by $0.86, net of tax, for the year ended December 31, 2024. In addition to the Company's change in accounting estimate, the year-over-year increase can also be attributed to an increase in the cost for replacement revenue equipment compared to the cost of retired equipment and to the interaction of a decrease in operating revenues with the fixed-cost nature of depreciation expense.

Impairment loss accounted for 1.5% of revenues, before fuel surcharges, during 2024. The Company has not previously recognized an impairment loss on long-lived assets. Management determined that market conditions for used revenue equipment had deteriorated since its peak in 2022. This decline in market conditions prompted the requirement for a recoverability test and subsequent impairment charge against certain asset groups of used trucks and trailers. Management tested all applicable asset groups and determined specific asset groups of trucks and trailers to be impaired beyond their carrying value. The impairment of these asset groups resulted in an impairment loss of approximately $6.4 million, or $0.22 loss per share, net of tax, during the year ended December 31, 2024. No impairment loss was incurred during the year ended December 31, 2023.

Insurance and claims decreased from 6.7% of revenues, before fuel surcharges, during 2023 to 4.6% of revenues, before fuel surcharges, during 2024. The decrease is primarily attributable to a decrease in auto liability claims incurred during the year ended December 31, 2024 compared to the year ended December 31, 2023. This decrease was slightly offset by an increase in the rate per mile paid for auto liability insurance during 2024 compared to 2023.

Non-operating income increased from 1.2% of revenues, before fuel surcharges, during 2023 to 1.9% of revenues, before fuel surcharges, during 2024. This increase resulted primarily from an increase in the market value of our marketable equity securities portfolio and an increase in the Company's net realized gains from the sale of certain marketable equity securities during the year-ended December 31, 2024 as compared to the year ended December 31, 2023.

Interest expense increased from 1.6% of revenues, before fuel surcharges, during 2023 to 2.9% of revenues, before fuel surcharges, during 2024. The increase is attributed to the Company's increased long-term debt from $261.7 million at December 31, 2023 to $325.6 million at December 31, 2024, coupled with an increase in interest rates as the Company's weighted average interest rate increased from 4.20% in 2023 to 5.00% in 2024.

The truckload services division operating ratio, which measures the ratio of operating expenses, net of fuel surcharges, to operating revenues, before fuel surcharges, increased to 111.2% for 2024 from 97.7% for 2023.

2023 Compared to 2022

For the year ended December 31, 2023, truckload services revenue, before fuel surcharges, decreased 14.8% to $460.9 million as compared to $540.9 million for the year ended December 31, 2022. The decrease relates primarily to a 14.2% decrease in our rate per loaded mile, from $2.92 for the year ended December 31, 2022 to $2.51 for the year ended December 31, 2023 and to a 0.8% decrease in loaded miles from 185.0 million for the year ended December 31, 2022 to 183.8 million for the year ended December 31, 2023. The decrease in rate per loaded mile reflects the challenging freight rate environment across our industry during 2023, while the slight reduction in loaded miles was largely due to the impacts of the automotive plant shutdowns during the UAW strikes in September and October 2023, partially offset by an increase in our average truck count during 2023 attributable to the acquisition of Metropolitan Trucking assets in June 2022.

Salaries, wages and benefits increased from 31.3% of revenues, before fuel surcharges, during 2022 to 37.8% of revenues, before fuel surcharges, during 2023. The percentage-based increase relates primarily to an increase in the percentage of miles driven by company-employed drivers, as opposed to third-party owner-operators for the year-ended December 31, 2023 compared to December 31, 2022. The increase also relates to the interaction of a decrease in operating revenues with the fixed-cost nature of employing human capital.

Operating supplies and expenses increased from 6.8% of revenues, before fuel surcharges, during 2022 to 11.8% of revenues, before fuel surcharges, during 2023. The increase relates primarily to the interaction of expenses with fixed-cost characteristics, such as rents, driver training schools and operating taxes and licenses with a decrease in revenue. The increase also relates to an increase in the average surcharge-adjusted fuel price paid per gallon of diesel fuel, due to decreased fuel surcharge collections from customers for the year ended December 31, 2023 compared to December 31, 2022.

Rent and purchased transportation decreased from 26.0% of revenues, before fuel surcharges, during 2022 to 23.5% of revenues, before fuel surcharges, during 2023. The decrease was primarily due to a decrease in the percentage of miles driven by third-party owner-operators as opposed to company-employed drivers for the year-ended December 31, 2023 compared to December 31, 2022. The decrease also relates to a decrease in the rates paid to third-party owner-operators for the year ended December 31, 2023 compared to the year ended December 31, 2022.

Depreciation increased from 11.3% of revenues, before fuel surcharges, during 2022 to 13.8% of revenues, before fuel surcharges, during 2023. The increase relates primarily to an increase in cost for replacement revenue equipment compared to the cost of retired equipment and to the interaction of a decrease in operating revenues with the fixed-cost nature of depreciation expense.

Insurance and claims increased from 6.0% of revenues, before fuel surcharges, during 2022 to 6.7% of revenues, before fuel surcharges, during 2023. This increase relates primarily to an increase in the rate per mile paid for auto liability insurance combined with a decrease in our revenue rate per mile.

Non-operating income increased from 0.5% of revenues, before fuel surcharges, during 2022 to 1.2% of revenues, before fuel surcharges, during 2023. This increase resulted primarily from an increase in interest income recognized, as well as a larger increase in the market value of our marketable equity securities portfolio at December 31, 2023 as compared to December 31, 2022.

The truckload services division operating ratio, which measures the ratio of operating expenses, net of fuel surcharges, to operating revenues, before fuel surcharges, increased to 97.7% for 2023 from 83.7% for 2022.

Results of Operations - Logistics and Brokerage Services

The following table sets forth, for logistics and brokerage services, the percentage relationship of expense items to operating revenues, before fuel surcharges, for the periods indicated. Brokerage service operations occur specifically in certain divisions; however, brokerage operations occur throughout the Company in similar operations having substantially similar economic characteristics. Rent and purchased transportation, which includes costs paid to third-party carriers, are shown net of fuel surcharges.

		Years Ended December 31,
		2024				2023				2022
Operating revenues, before fuel surcharge			100.0	%			100.0	%			100.0	%
Operating expenses:
Salaries, wages and benefits			5.1				4.9				4.6
Rent and purchased transportation			86.6				84.6				80.8
Other			3.2				2.4				1.8
Total operating expenses			94.9				91.9				87.2
Operating income			5.1				8.1				12.8
Non-operating income			0.2				0.8				0.2
Interest expense			(0.4	)			(0.7	)			(0.5	)
Income before income taxes			4.8	%			8.2	%			12.5	%

2024 Compared to 2023

For the year ended December 31, 2024, logistics and brokerage services revenues, before fuel surcharges, decreased 15.6% to $207.0 million as compared to $245.2 million for the year ended December 31, 2023. The decrease relates to a reduction in the average rates charged to customers year to year, while total brokered loads remained flat. The truckload market continues to be negatively impacted by downward rate pressure driven by the challenging truckload rate environment.

Rent and purchased transportation increased from 84.6% of revenues, before fuel surcharges, in 2023 to 86.6% of revenues, before fuel surcharges, in 2024. The increase results from paying third-party carriers a larger percentage of customer revenue, coupled with the interaction of a decrease in operating revenues with the need for purchased transportation.

The logistics and brokerage services division operating ratio, which measures the ratio of operating expenses, net of fuel surcharges, to operating revenues, before fuel surcharges, increased to 94.9% for 2024 from 91.9% for 2023.

2023 Compared to 2022

For the year ended December 31, 2023, logistics and brokerage services revenues, before fuel surcharges, decreased 11.7% to $245.2 million as compared to $277.8 million for the year ended December 31, 2022. The decrease was primarily related to a 21.4% decrease in revenue per load, partially offset by a 12.3% increase in the number of loads during 2023 as compared to 2022. The decrease in revenue per load was due to a reduction in rates paid for brokered loads during 2023, as spot market rates were negatively impacted by downward rate pressure driven by the challenging truckload freight rate environment across our industry during 2023.

Rent and purchased transportation increased from 80.8% of revenues, before fuel surcharges, in 2022 to 84.6% of revenues, before fuel surcharges, in 2023. The increase results from paying third-party carriers a larger percentage of customer revenue, coupled with the interaction of a decrease in operating revenues with the need for purchased transportation.

The logistics and brokerage services division operating ratio, which measures the ratio of operating expenses, net of fuel surcharges, to operating revenues, before fuel surcharges, increased to 91.9% for 2023 from 87.2% for 2022.

Results of Operations - Combined Services

2024 Compared to 2023

Income tax benefit was approximately $9.8 million in 2024, resulting in an effective rate of 23.5%, as compared to income tax expense of approximately $10.2 million, or an effective tax rate of 35.6% in 2023. The effective tax rate is impacted by the effect of state taxes and other factors.

In determining whether a tax asset valuation allowance is necessary, management, in accordance with the provisions of Accounting Standards Codification ("ASC") 740-10-30, weighs all available evidence, both positive and negative to determine whether, based on the weight of that evidence, a valuation allowance is necessary. If negative conditions exist which indicate a valuation allowance might be necessary, consideration is then given to what effect the future reversals of existing taxable temporary differences and the availability of tax strategies might have on future taxable income to determine the amount, if any, of the required valuation allowance. As of December 31, 2024, management determined that the future reversals of existing taxable temporary differences and available tax strategies would generate sufficient future taxable income to realize its tax assets and therefore a valuation allowance was not necessary.

The Company recognizes a tax benefit from an uncertain tax position only if it is more likely than not that the position will be sustained on examination by taxing authorities, based on the technical merits of the position. As of December 31, 2024, an adjustment to the Company's consolidated financial statements for uncertain tax positions has not been required as management believes that the Company's tax positions taken in income tax returns filed or to be filed are supported by clear and unambiguous income tax laws. The Company recognizes interest and penalties related to uncertain income tax positions, if any, in income tax expense. During 2024 and 2023, the Company has not recognized or accrued any interest or penalties related to uncertain income tax positions.

The Company and its subsidiaries are subject to U.S. and Canadian federal income tax laws as well as the income tax laws of multiple state jurisdictions. The major tax jurisdictions in which we operate generally provide for a deficiency assessment statute of limitation period of three years and as a result, the Company's tax years 2021 and forward remain open to examination in those jurisdictions.

The combined net loss for all divisions was $31.8 million, or 5.1% of revenues, before fuel surcharge, for 2024 as compared to the combined net income for all divisions of $18.4 million or 2.6% of revenues, before fuel surcharge, for 2023. Diluted (loss) earnings per share decreased to ($1.45) for the year ended December 31, 2024 from $0.83 for the year ended December 31, 2023.

2023 Compared to 2022

Income tax expense was approximately $10.2 million in 2023, resulting in an effective rate of 35.6%, as compared to approximately $28.3 million, or an effective tax rate of 23.8% in 2022. The effective tax rate is impacted by the effect of state taxes and other factors.

During 2023 and 2022, the Company has not recognized or accrued any interest or penalties related to uncertain income tax positions.

The combined net income for all divisions was $18.4 million, or 2.6% of revenues, before fuel surcharge, for 2023 as compared to the combined net income for all divisions of $90.7 million or 11.1% of revenues, before fuel surcharge, for 2022. Diluted earnings per share decreased to $0.83 for the year ended December 31, 2023 from $4.04 for the year ended December 31, 2022.

Liquidity and Capital Resources

Our business has required, and will continue to require, a significant investment in new revenue equipment. Our primary sources of liquidity have been funds provided by operations, proceeds from the sales of revenue equipment, borrowings under our lines of credit, installment notes, investment margin account, and issuances of equity securities.

During 2024, we generated $59.0 million in cash from operating activities compared to $114.6 million and $168.8 million in 2023 and 2022, respectively. Investing activities used $100.2 million in cash during 2024 compared to using $11.3 million and $113.5 million in 2023 and 2022, respectively. Financing activities generated $8.6 million in cash during 2024 compared to using $76.8 million during 2023 and generating $0.3 million during 2022. See the Consolidated Statements of Cash Flows in Item 8 of this Report.

Our primary use of funds is for the purchase of revenue equipment. We typically use installment notes, our existing lines of credit on an interim basis, proceeds from the sale or trade of equipment, and cash flows from operations to finance capital expenditures and repay long-term debt. During 2024 and 2023, we utilized cash on hand, installment notes, and our lines of credit to finance revenue equipment purchases of approximately $143.5 million and $113.5 million, respectively.

We often finance the acquisition of revenue equipment through installment notes with fixed interest rates. At December 31, 2024, the Company's subsidiaries had combined outstanding indebtedness under such installment notes of $325.6 million. These installment notes are payable in monthly installments, ranging from 60 monthly installments to 84 monthly installments, at a weighted average interest rate of 5.00%. At December 31, 2023, the Company's subsidiaries had combined outstanding indebtedness under such installment notes of $261.7 million. These installment notes were payable in monthly installments, ranging from 36 to 84 months at a weighted average interest rate of 4.20%.

In order to maintain an adequate pool of available equipment, it is often necessary to purchase replacement equipment and place them in service before trucks and trailers scheduled for replacement are removed from service. The timing of this process often requires the Company to pay for new equipment before receiving any proceeds from retired equipment, or without any reduction in price for trade units. In this situation, the Company later receives payment for the equipment scheduled for replacement once they are delivered to the buyer and have passed inspection. During the twelve months ended December 31, 2024 and 2023, the Company received approximately $36.9 million and $22.6 million, respectively, for disposed revenue equipment.

During 2024, we maintained a revolving line of credit with a borrowing limit of $60.0 million. Under this credit facility, amounts outstanding under the line bear interest at Term SOFR plus 1.85% (6.42% at December 31, 2024), are secured by our trade accounts receivable and mature on July 1, 2027. The credit facility also establishes an "unused fee" of 0.25% if average borrowings are less than $18.0 million. At December 31, 2024, we had no outstanding borrowings against the line of credit and approximately $0.2 million of outstanding letters of credit, with availability to borrow $59.8 million.

Trade accounts receivable remained relatively flat year-over-year, with a balance of $80.0 million at December 31, 2024 compared to $80.6 million at December 31, 2023.

Marketable equity securities at December 31, 2024 decreased approximately $0.6 million as compared to December 31, 2023. The decrease resulted from the sales of marketable equity securities approximating $3.7 million offset by an increase in the market value of the portfolio by approximately $3.1 million. At December 31, 2024, the remaining marketable equity securities have a combined cost basis of approximately $27.1 million and a combined fair market value of approximately $42.6 million. The Company has developed a strategy to invest in securities from which it expects to receive dividends that qualify for favorable tax treatment, as well as appreciate in value. During 2024, the Company received dividends of approximately $1.5 million. The holding term of these securities depends largely on the general economic environment, the equity markets, borrowing rates, and the Company's cash requirements.

Property and equipment increased by approximately $65.4 million from $771.1 as of December 31, 2023 to $836.5 million as of December 31,2024. This increase is primarily attributable to the purchase of $144.2 million of revenue equipment partially offset by the disposal of approximately $93.8 million of revenue equipment during 2024. Also contributing to the increase was the purchase of property in El Paso, Texas that will serve as an additional terminal for our truckload operations and the construction of a driver training facility at our corporate headquarters in Tontitown, Arkansas. Partially offsetting the increase to property and equipment was an impairment loss of $6.4 million which resulted from management's assessment that the market conditions for used revenue equipment had deteriorated to an extent that required a test for recoverability and subsequent impairment charge against certain asset groups of used trucks and trailers.

Accounts payable decreased from $62.7 million at December 31, 2023 to $31.2 million at December 31, 2024. This decrease was primarily attributable to payments made during 2024 for new revenue equipment that was invoiced or delivered, but not yet paid as of December 31, 2023. This decrease was also attributable to a decrease in the amounts payable to third party carriers as of December 31, 2024. Accounts payable accruals can vary significantly at the end of each reporting period depending on the timing of the actual date of payment in relation to the last day of the reporting period.

Accrued expenses and other liabilities decreased from $16.8 million at December 31, 2023 to $14.6 million at December 31, 2024. The decrease is primarily attributable to a decrease in auto liability claims accrued during the year ended December 31, 2024 compared to auto liability claims accrued for the year ended December 31, 2023.

For 2025, we expect to purchase 293 new trucks and 300 trailers while continuing to sell or trade equipment that has reached the end of its life cycle. Management believes we will be able to finance our existing needs for working capital over the next twelve months, as well as acquisitions of revenue equipment and any other asset acquisitions or capital transactions during such period, with cash balances, cash flows from operations, and borrowings believed to be available from financing sources. We will continue to have significant capital requirements over the long-term, which may require us to incur debt or seek additional equity capital. The availability of additional capital will depend upon prevailing market conditions, the market price of our common stock and several other factors over which we have limited control, as well as our financial condition and results of operations. Nevertheless, based on our anticipated future cash flows and sources of financing that we expect will be available to us, we do not expect that we will experience any significant liquidity constraints in the foreseeable future.

Inflation

Inflation has an impact on most of our operating costs. Over the past three years, the effect of inflation has been significant. If the current rate of inflation persists, inflation, coupled with supply chain issues and international events could continue to result in increased costs for drivers, employee wages, equipment, fuel and other costs.

Adoption of Accounting Policies

See "Item 8. Financial Statements and Supplementary Data, Note 1 to the Consolidated Financial Statements - Accounting Policies, Recent Accounting Pronouncements."

Critical Accounting Estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to adopt accounting policies and make significant judgments and estimates that impact the amounts reported in our consolidated financial statements and accompanying notes. Therefore, the reported amounts of assets, liabilities, revenue, expenses, and associated disclosures of contingent assets and liabilities are affected by judgments and estimates. In some cases, there are alternative assumptions, policies, or estimation techniques that could be used. Management evaluates its assumptions, policies, and estimates on an ongoing basis, utilizing historical experience, and other methods considered reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from our estimates and assumptions, and it is possible that materially different amounts would be reported using differing estimates or assumptions. Management considers our critical accounting estimates to be those that require more significant judgments and estimates when we prepare our consolidated financial statements.

Note 1 in Part II, Item 8 of this Annual Report describes the Company's accounting policies. The following discussion of accounting estimates should be read in conjunction with Note 1, as it provides additional insight into critical accounting estimates. Our critical accounting estimates include the following:

Depreciation and Amortization. Depreciation of trucks and trailers is calculated by the straight-line method over the assets' estimated useful lives, which generally range from three to ten years, down to an estimated salvage value at the end of the assets' estimated useful lives. Management must use its judgment in the selection of estimated useful lives and salvage values for purposes of this calculation. In some cases, the Company has agreements in place with certain manufacturers whereby salvage values are guaranteed by the manufacturer. In other cases, where salvage values are not guaranteed, estimates of salvage value are based on the expected market values of equipment at the time of disposal.

The depreciation of trucks and trailers over their estimated useful lives and the determination of any salvage value also require management to make judgments about future events. Therefore, the Company's management periodically evaluates whether changes to estimated useful lives or salvage values are necessary to ensure these estimates accurately reflect the economic reality of the assets. This periodic evaluation may result in changes in the estimated lives and/or salvage values used by the Company to depreciate its assets, which can affect the amount of periodic depreciation expense recognized and, ultimately, the gain or loss on the disposal of an asset. Future changes in our estimated useful life or salvage value estimates, or fluctuations in market value that are not reflected in current estimates, could have a material effect on the Company's consolidated financial statements.

During the year ended December 31, 2024, the Company conducted a review of its revenue equipment and determined that changes in market conditions and expected asset usage warranted a revision to the estimated useful lives and salvage values of certain equipment. As a result, during the year ended December 31, 2024, the Company reduced the estimated useful lives of its trailer equipment and lowered the estimated salvage values of revenue equipment to better reflect their expected residual values at the end of their service periods.

In accordance with ASC 250-10-45-17, this change is considered a change in accounting estimate and has been applied prospectively during the year ended December 31, 2024. The effect of this change increased depreciation expense by $24.7 million and increased basic and diluted loss per share by $0.86 net of tax, for the year ended December 31, 2024.

Impairment of Long-Lived Assets. We review our property, plant, and equipment and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Indicators of impairment may include, but are not limited to, declining operating performance, adverse changes in market conditions, regulatory developments, or planned asset dispositions.

When an indicator of impairment is identified, we perform a recoverability test by comparing the undiscounted future cash flows expected to be generated by the asset group to its carrying amount. If the carrying amount exceeds the undiscounted cash flows, we recognize an impairment loss equal to the excess of the carrying amount over the asset's fair value. Fair value is typically estimated using a combination of market prices (if available), appraisals, or discounted cash flow analyses. The determination of fair value involves significant management judgment, including assumptions about future revenue growth, operating costs, asset utilization, and discount rates.

During the year ended December 31, 2024, management determined that the market conditions for used revenue equipment had deteriorated since its peak in 2022. This decline in market conditions prompted the requirement for a recoverability test and subsequent impairment charge against certain asset groups of used trucks and trailers. Management tested all applicable asset groups and determined certain asset groups of used trucks and trailers to be impaired beyond their carrying value. The impairment of these asset groups resulted in an impairment loss of approximately $6.4 million, or $0.22 loss per share, net of tax, during the year ended December 31, 2024.

If our business is negatively impacted by prolonged economic downturns, the market for used equipment may decline and our ability to generate cash from the utilization of our equipment could decrease, necessitating future impairment charges. Conversely, an improvement in market conditions or operational performance may reduce the likelihood of future impairments.

Management will continue to monitor our property, plant, and equipment and other long-lived assets for impairment as necessary. Additional impairment charges, if any, could have a material impact on our financial position and results of operations.

Claims accruals. The Company is self-insured for health and workers' compensation benefits up to certain stop-loss limits. Such costs are accrued based on known claims and an estimate of incurred but not reported (IBNR) claims. IBNR claims are estimated using historical lag information and other data either provided by outside claims administrators or developed internally. Actual claims payments may differ from management's estimates as a result of a number of factors, including evaluation of severity, increases in legal or medical costs, and other case-specific factors. The actual claims payments are charged against the Company's recorded accrued claims liabilities and have been historically reasonable with respect to the estimates of the liabilities made under the Company's methodology. However, the estimation process is generally subjective, and to the extent that future actual results materially differ from original estimates made by management, adjustments to recorded accruals may be necessary which could have a material effect on the Company's consolidated financial statements. Based upon our 2024 health and workers' compensation expenses, a 10% increase in both claims incurred and IBNR claims would increase our annual health and workers' compensation expenses by approximately $0.9 million.

On September 1, 2020, the Company elected to become self-insured for certain layers of auto liability claims in excess of $2.0 million. The Company specifically reserves for claims that are expected to exceed $2.0 million when fully developed, based on the facts and circumstances of those claims.
