Significant Accounting Policies	Dec. 31, 2022
Significant Accounting Policies	(1) Significant Accounting Policies Consolidation The consolidated financial statements include the accounts of Landstar System, Inc. and its subsidiary, Landstar System Holdings, Inc. (“LSHI”). Landstar System, Inc. and its subsidiary are herein referred to as “Landstar” or the “Company.” Significant intercompany accounts have been eliminated in consolidation. Estimates The preparation of the consolidated financial statements requires the use of management’s estimates. Actual results could differ from those estimates. Fiscal Year Landstar’s fiscal year is the 52 or 53 week period ending the last Saturday in December. Revenue Recognition The nature of the Company’s freight transportation services and its performance obligations to customers, regardless of the mode of transportation used to perform such services, relate to the safe and on-time pick-up shipment-by-shipment shipment-by-shipment pre-defined (30-60) pick-up pick-up Revenue from Contracts with Customers – Disaggregation of Revenue The following table summarizes (i) the percentage of consolidated revenue generated by mode of transportation and (ii) the total amount of truck transportation revenue hauled by BCO Independent Contractors and Truck Brokerage Carriers generated by equipment type during the fiscal years ended December 31, 2022, December 25, 2021 and December 26, 2020 (dollars in thousands): Fiscal Years Ended Mode December 31, 2022 December 25, 2021 December 26, 2020 Truck – BCO Independent Contractors 35 % 40 % 45 % Truck – Truck Brokerage Carriers 54 % 51 % 47 % Rail intermodal 2 % 2 % 3 % Ocean and air cargo carriers 8 % 5 % 3 % Truck Equipment Type Van equipment $ 3,892,085 $ 3,525,830 $ 2,192,254 Unsided/platform equipment $ 1,760,357 $ 1,549,037 $ 1,119,272 Less-than-truckload $ 142,438 $ 117,505 $ 97,546 Other truck transportation (1) $ 835,959 $ 770,846 $ 406,709 (1) Includes power-only, expedited, straight truck, cargo van, and miscellaneous other truck transportation revenue generated by the transportation logistics segment. Power-only refers to shipments where the Company furnishes a power unit and an operator but not trailing equipment, which is typically provided by the shipper or consignee. Insurance Claim Costs Landstar provides, primarily on an actuarially determined basis, for the estimated costs of cargo, property, casualty, general liability and workers’ compensation claims both reported and for claims incurred but not reported. For periods prior to May 1, 2019, Landstar retains liability for commercial trucking claims up to $5 million per occurrence and maintains various third party insurance arrangements for liabilities in excess of its $5 million self-insured retention. Effective May 1, 2019, the Company entered into a new three year commercial auto liability insurance arrangement for losses incurred between $5 million and $10 million (the “Initial Excess Policy”) with a third party insurance company. The Company subsequently extended the Initial Excess Policy for one additional policy year, from May 1, 2022 through April 30, 2023. For commercial trucking claims incurred on or after May 1, 2022 through April 30, 2023, the extended Initial Excess Policy provides for a limit for a single loss of $5 million, with a remaining aggregate limit of $10 million for the policy period ending April 30, 2023, and an option to increase such aggregate limit for a pre-established pre-established The Company also maintains third party insurance arrangements providing excess coverage for commercial trucking liabilities in excess of $10 million. These third party arrangements provide coverage on a per occurrence or aggregated basis. In recent years, the Company has increased the level of its financial exposure to commercial trucking claims in excess of $10 million, including through the use of additional self-insurance, deductibles, aggregate loss limits, quota shares and other arrangements with third party insurance companies, based on the availability of coverage within certain excess insurance coverage layers and estimated cost differentials between proposed premiums from third party insurance companies and historical and actuarially projected losses experienced by the Company at various levels of excess insurance coverage. Further, the Company retains liability of up to $1,000,000 for each general liability claim, up to $250,000 for each workers’ compensation claim and up to $250,000 for each cargo claim. In addition, under reinsurance arrangements by Signature of certain risks of the Company’s BCO Independent Contractors, the Company retains liability of up to $500,000, $1,000,000 or $2,000,000 with respect to certain occupational accident claims and up to $750,000 with respect to certain workers’ compensation claims. Tires Tires purchased as part of trailing equipment are capitalized as part of the cost of the equipment. Replacement tires are charged to expense when placed in service. Cash, Cash Equivalents and Restricted Cash Included in cash and cash equivalents are all investments, except those provided for collateral, with an original maturity of 3 months or less. At December 25, 2021, the Company had $4,049,000 of restricted cash held by the Company’s insurance segment included in the short-term investments balance of $35,778,000, providing collateral, along with certain other investments, for the letters of credit issued to guarantee payment of insurance claims. Financial Instruments The Company’s financial instruments include cash equivalents, short and long-term investments, trade and other accounts receivable, accounts payable, other accrued liabilities, and long-term debt plus current maturities (“Debt”). The carrying value of cash equivalents, trade and other accounts receivable, accounts payable, current insurance claims and other accrued liabilities approximates fair value as the assets and liabilities are short term in nature. Short and long-term investments are carried at fair value as further described in Note 4 in the Company’s consolidated financial statements. The Company’s Debt includes borrowings under the Company’s revolving credit facility, to the extent there are any, plus borrowings relating to finance lease obligations used to finance trailing equipment. The interest rates on borrowings under the revolving credit facility are typically tied to short-term interest rates that adjust monthly and, as such, carrying value approximates fair value. Interest rates on borrowings under finance leases approximate the interest rates that would currently be available to the Company under similar terms and, as such, carrying value approximates fair value. Trade and Other Receivables The allowance for doubtful accounts for both trade and other receivables represents management’s estimate of the amount of outstanding receivables that will not be collected. Estimates are used to determine the allowance for doubtful accounts for both trade and other receivables and are generally based on specific identification, historical collection results, current economic trends and changes in payment trends. Following is a summary of the activity in the allowance for doubtful accounts for fiscal years ending December 31, 2022, December 25, 2021 and December 26, 2020 (in thousands): Balance at Beginning of Period Charged to Costs and Expenses Write-offs, Net of Recoveries Balance at End of Period For the Fiscal Year Ended December 31, 2022 Trade receivables $ 7,074 $ 7,354 $ (2,307 ) $ 12,121 Other receivables 9,511 4,863 (2,629 ) 11,745 Other non-current 200 3 — 203 $ 16,785 $ 12,220 $ (4,936 ) $ 24,069 For the Fiscal Year Ended December 25, 2021 Trade receivables $ 8,670 $ 1,735 $ (3,331 ) $ 7,074 Other receivables 8,399 4,050 (2,938 ) 9,511 Other non-current 264 (63 ) (1 ) 200 $ 17,333 $ 5,722 $ (6,270 ) $ 16,785 For the Fiscal Year Ended December 26, 2020 Trade receivables $ 7,284 $ 6,121 $ (4,735 ) $ 8,670 Other receivables 8,806 3,291 (3,698 ) 8,399 Other non-current 260 3 1 264 $ 16,350 $ 9,415 $ (8,432 ) $ 17,333 Operating Property Operating property is recorded at cost. Depreciation is provided on a straight-line basis over the estimated Goodwill Goodwill represents the excess of the purchase price paid over the fair value of the net assets of acquired businesses. The Company has two reporting units within the transportation logistics segment that report goodwill. The Company reviews its goodwill balance annually for impairment for each reporting unit, unless circumstances dictate more frequent assessments, and in accordance with ASU 2011-08, Testing Goodwill for Impairment 2011-08 Income Taxes Income tax expense is equal to the current year’s liability for income taxes and a provision for deferred income taxes. Deferred tax assets and liabilities are recorded for the future tax effects attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to be applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. Share-Based Payments The Company’s share-based payment arrangements include restricted stock units (“RSU”), non-vested non-vested non-vested Earnings Per Share Earnings per common share are based on the weighted average number of shares outstanding, including outstanding non-vested non-vested For the fiscal years ended December 31, 2022, December 25, 2021 and December 26, 2020, no options outstanding to purchase shares of Common Stock were antidilutive. Outstanding RSUs were excluded from the calculation of diluted earnings per share for all periods because the performance metric requirements or market condition for vesting had not been satisfied. Dividends Payable On December 6, 2022, the Company announced that its Board of Directors declared a special cash dividend of $2.00 per share payable on On December 7, 2021, the Company announced that its Board of Directors declared a special cash dividend of $2.00 per share payable on Foreign Currency Translation Assets and liabilities of the Company’s Canadian and Mexican operations are translated from their functional currency to U.S. dollars using exchange rates in effect at the balance sheet date and revenue and expense accounts are translated at average monthly exchange rates during the period. Adjustments resulting from the translation process are included in accumulated other comprehensive income. Transactional gains and losses arising from receivable and payable balances, including intercompany balances, in the normal course of business that are denominated in a currency other than the functional currency of the operation are recorded in the statements of income when they occur.

Acquired Business	Dec. 31, 2022
Acquired Business	(2) Acquired Business On May 6, 2020, the Company formed a new subsidiary that was subsequently renamed Landstar Blue, LLC (“Landstar Blue”). Landstar Blue arranges truckload brokerage services with a focus on the contract services market. Landstar Blue also helps the Company to develop and test digital technologies and processes for the benefit of all Landstar independent commission sales agents. On June 15, 2020, Landstar Blue completed the acquisition of an independent agent of the Company whose business focused on truckload brokerage services. Cash consideration paid for the acquisition was approximately $2,766,000. In addition, the Company assumed approximately $200,000 in liabilities consisting of additional contingent purchase price, of which $168,000 was remitted during the Company’s 2021 second fiscal quarter. The resulting goodwill arising from the acquisition was approximately $2,871,000. With respect to this goodwill, 100% is expected to be deductible by the Company for U.S. income tax purposes. Pro forma financial information for prior periods is not presented as the Company does not believe the acquisition to be material to the Company’s consolidated results. The results of operations for Landstar Blue are presented as part of the Company’s transportation logistics segment. Transaction costs for the acquisition were insignificant.

The Company expects to recover, through collection of all of the contractual cash flows of each security, the amortized cost basis of these securities as it does not intend to sell, and does not anticipate being required to sell, these securities before recovery of the cost basis. For these reasons, no losses have been recognized in the Company’s consolidated statements of income. Short-term investments include $53,955,000 in current maturities of investments held by the Company’s insurance segment at December 31, 2022. The non-current non-current Investment income represents the earnings on the insurance segment’s assets. Investment income earned from the assets of the insurance segment are included as a component of operating income as the investment of these assets is critical to providing collateral, liquidity and earnings with respect to the operation of the Company’s insurance programs.

Debt	Dec. 31, 2022
Debt	(8) Debt Other than the finance lease obligations as presented on the consolidated balance sheets, the Company had no outstanding debt as of December 31, 2022 and December 25, 2021. On August 18, 2020, Landstar entered into an amended and restated credit agreement with a syndicate of banks and JPMorgan Chase Bank, N.A., as administrative agent (the “First Amended and Restated Credit Agreement”). As previously disclosed in a Form 8-K The Second Amended and Restated Credit Agreement, which superseded and replaced the First Amended and Restated Credit Agreement, is referred to herein as the “Credit Agreement.” As of December 31, 2022 and December 25, 2021, the Company had no borrowings outstanding under the Credit Agreement. The revolving credit loans under the Credit Agreement, at the option of Landstar, bear interest at (i) a forward-looking term rate based on the secured overnight financing rate plus 0.10% and an applicable margin ranging from 1.25% to 2.00%, or (ii) an alternate base rate plus an applicable margin ranging from 0.25% to 1.00%, in each case with the applicable margin determined based upon the Company’s Leverage Ratio, as defined in the Credit Agreement, at the end of the most recent applicable fiscal quarter for which financial statements have been delivered. The revolving credit facility bears a commitment fee, payable quarterly in arrears, of 0.20% to 0.30%, based on the Company’s Leverage Ratio at the end of the most recent applicable fiscal quarter for which financial statements have been delivered. The Credit Agreement contains a number of covenants that limit, among other things, the incurrence of additional indebtedness. The Company is required to, among other things, maintain a minimum fixed charge coverage ratio, as described in the Credit Agreement, and maintain a Leverage Ratio, as defined in the Credit Agreement, below a specified maximum. The Credit Agreement provides for a restriction on cash dividends and other distributions to stockholders on the Company’s capital stock to the extent there is a default under the Credit Agreement. In addition, the Credit Agreement under certain circumstances limits the amount of such cash dividends and other distributions to stockholders to the extent that, after giving effect to any payment made to effect such cash dividend or other distribution, the Leverage Ratio would exceed 2.5 The interest rates on borrowings under the revolving credit facility are typically tied to short-term interest rates and, as such, carrying value approximates fair value. Interest rates on borrowings under finance leases approximate the interest rates that would currently be available to the Company under similar terms and, as such, carrying value approximates fair value. Landstar paid interest of $4,151,000 in fiscal year 2022, $3,715,000 in fiscal year 2021 and $3,915,000 in fiscal year 2020.

Leases

Leases	12 Months Ended
Leases	Dec. 31, 2022
Leases	(9) Leases Landstar’s noncancelable leases are primarily comprised of finance leases for the acquisition of new trailing equipment. Each finance lease for the acquisition of trailing equipment is a five year lease with a $1 purchase option for the applicable equipment at lease expiration. Substantially all of Landstar’s operating lease right-of-use build-out “month-to-month” Most of Landstar’s operating leases include one or more options to renew. The exercise of lease renewal options is typically at Landstar’s sole discretion, and, as such, the majority of renewals to extend the lease terms are not included in the right-of-use As most of Landstar’s operating leases do not provide an implicit rate, Landstar utilized its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. Landstar has a centrally managed treasury function; therefore, based on the applicable lease terms and the current economic environment, the Company applies a portfolio approach for determining the incremental borrowing rate. The components of lease cost for finance leases and operating leases as of December 31, 2022 were (in thousands): Finance leases: Amortization of right-of-use $ 22,071 Interest on lease liability 2,908 Total finance lease cost 24,979 Operating leases: Lease cost 3,495 Variable lease cost — Sublease income (5,616 ) Total net operating lease income (2,121 ) Total net lease cost $ 22,858 Total net operating lease income, net of rent expense under operating leases, was $1,632,000 and $1,620,000 in fiscal years 2021 and 2020, respectively.

With respect to RSU awards with a performance condition, the amount of future compensation expense to be recognized will be determined based on future operating results. Non-vested The 2011 EIP provides the Compensation Committee of the Board of Directors with the authority to issue shares of Common Stock of the Company, subject to certain vesting and other restrictions on transfer (“restricted stock”). The following table summarizes information regarding the Company’s outstanding shares of non-vested Number of Shares and Deferred Stock Units Weighted Average Fair Value Non-vested 64,808 $ 98.24 Granted 26,604 $ 111.88 Vested (28,621 ) $ 98.83 Forfeited (2,351 ) $ 106.34 Non-vested 60,440 $ 103.65 Granted 26,351 $ 150.20 Vested (29,055 ) $ 104.35 Forfeited (1,300 ) $ 97.81 Non-vested 56,436 $ 125.16 Granted 25,354 $ 152.54 Vested (27,074 ) $ 122.68 Forfeited (6,921 ) $ 144.45 Non-vested 47,795 $ 138.30 Th non-vested the Company’s Common Stock on the date of grant. Shares of non-vested restricted stock are generally subject to vesting in three equal annual installments either on the first, second and third anniversary of the date of grant or the third, fourth and fifth anniversary of the date of the grant, or 100% on the first or fifth anniversary of the date of the grant. For restricted stock awards granted under the 2022 DSCP plan, each recipient may elect to defer receipt of shares and instead receive restricted stock units (“Deferred Stock Units”), which represent contingent rights to receive shares of the Company’s Common Stock on the date of recipient separation from service from the Board of Directors, or, if earlier, upon a change in control event of the Company. Deferred Stock Units become vested 100% on the first anniversary of the date of the grant. Deferred Stock Units do not represent actual ownership in shares of the Company’s Common Stock and the recipient does not have voting rights or other incidents of ownership until the shares are issued. However, Deferred Stock Units do contain the right to receive dividend equivalent payments prior to settlement into shares. As of December 31, 2022, there was $3,449,000 of total unrecognized compensation cost related to non-vested non-vested Stock Options The Company did not grant any stock options during its 2020, 2021 or 2022 fiscal years. Options outstanding under the Plans generally become exercisable in either five equal annual installments commencing on the first anniversary of the date of grant or 100% on the fifth anniversary from the date of grant, subject to acceleration in certain circumstances. All options granted under the Plans expire on the tenth anniversary of the date of grant. Under the Plans, the exercise price of each option equals the fair market value of the Company’s Common Stock on the date of grant. The fair value of each option grant on its grant date was calculated using the Black-Scholes option pricing model. The Company utilized historical data, including exercise patterns and employee departure behavior, in estimating the term that options will be outstanding. Expected volatility was based on historical volatility and other factors, such as expected changes in volatility arising from planned changes to the Company’s business, if any. The risk-free interest rate was based on the yield of zero coupon U.S. Treasury bonds for terms that approximated the terms of the options granted. The following table summarizes information regarding the Company’s outstanding stock options under the Plans: Options Outstanding Options Exercisable Number of Options Weighted Average Exercise Price per Share Number of Options Weighted Average Exercise Price per Share Options at December 28, 2019 44,467 $ 51.24 44,467 $ 51.24 Exercised (26,817 ) $ 49.31 Options at December 26, 2020 17,650 $ 54.16 17,650 $ 54.16 Exercised (9,080 ) $ 52.97 Options at December 25, 2021 8,570 $ 55.42 8,570 $ 55.42 Exercised (6,670 ) $ 55.14 Options at December 31, 2022 1,900 $ 56.40 1,900 $ 56.40 All 1,900 stock options outstanding and exercisable at December 31, 2022 had an exercise price per share of $56.40 and weighted average remaining contractual life of 0.1 years. All 1,900 were exercised as of January 31 , following which the Company had no remaining issued and outstanding vested or unvested stock options At December 31, 2022, the total intrinsic value of options outstanding and exercisable was $202,000. The total intrinsic value of stock options exercised during fiscal years 2022, 2021 and 2020 was $704,000, $965,000 and $1,846,000, respectively. As of December 31, 2022, there was no unrecognized compensation cost related to non-vested Directors’ Stock Compensation Plan Directors of the Company who are not employees of the Company (each an “Eligible Director”) are entitled under the 2022 DSCP to receive a grant of such number of restricted shares of the Company’s Common Stock or Deferred Stock Units equal to the quotient of $ divided by the fair market value of a share of Common Stock on the date immediately following the date of each annual meeting of the stockholders of the Company (an “Annual Meeting”). Each eligible Director was previously entitled under the 2013 DSCP to receive a grant of such number of restricted shares of the Company’s Common Stock or Deferred Stock Units equal to the quotient of $ divided by the fair market value of a share of Common Stock on the date immediately following the date of each Annual Meeting. In fiscal year 2022, restricted shares were granted to Eligible Directors. In fiscal year 2021, restricted shares were granted to Eligible Directors. In fiscal year 2020, 4,890 restricted shares and 978 Deferred Stock Units were granted to Eligible Directors.

Commitments and Contingencies	(12) Commitments and Contingencies At December 31, 2022, in addition to the $76,567,000 letters of credit secured by investments, Landstar had $33,493,000 of letters of credit outstanding under the Company’s Credit Agreement. The Company is involved in certain claims and pending litigation arising from the normal conduct of business. Many of these claims are covered in whole or in part by insurance. Based on knowledge of the facts and, in certain cases, opinions of outside counsel, management believes that adequate provisions have been made for probable losses with respect to the resolution of all such claims and pending litigation and that the ultimate outcome, after provisions therefor, will not have a material adverse effect on the financial condition of the Company, but could have a material effect on the results of operations in a given quarter or year.

Segment Information	Dec. 31, 2022
Segment Information	(13) Segment Information Landstar markets its integrated transportation management solutions primarily through independent commission sales agents and exclusively utilizes third party capacity providers to transport customers’ freight. Landstar’s independent commission sales agents enter into contractual arrangements with the Company and are responsible for locating freight, making that freight available to Landstar’s capacity providers and coordinating the transportation of the freight with customers and capacity providers. The Company’s third party capacity providers consist of independent contractors who provide truck capacity to the Company under exclusive lease arrangements (the “BCO Independent Contractors”), unrelated trucking companies who provide truck capacity to the Company under non-exclusive The transportation logistics segment provides a wide range of integrated transportation management solutions. Transportation services offered by the Company include truckload, less-than-truckload and other truck transportation, rail intermodal, air cargo, ocean cargo, expedited ground and air delivery of time-critical freight, heavy-haul/specialized, U.S.-Canada and U.S.-Mexico cross-border, intra-Mexico, intra-Canada, project cargo and customs brokerage. Examples of the industries serviced by the transportation logistics segment include automotive parts and assemblies, consumer durables, building products, metals, chemicals, foodstuffs, heavy machinery, retail, electronics and military equipment. In addition, the transportation logistics segment provides transportation services to other transportation companies, including third party logistics and less-than-truckload service providers. The independent commission sales agents market services provided by the transportation logistics segment. Billings for freight transportation services are typically charged to customers on a per shipment basis for the physical transportation of freight and are referred to as transportation revenue. The results of operations from Landstar Blue and Landstar Metro are presented as part of the Company’s transportation logistics segment. The insurance segment is comprised of Signature Insurance Company (“Signature”), a wholly owned offshore insurance subsidiary, and Risk Management Claim Services, Inc. The insurance segment provides risk and claims management services to certain of Landstar’s operating subsidiaries. In addition, it reinsures certain risks of the Company’s BCO Independent Contractors and provides certain property and casualty insurance directly to certain of Landstar’s operating subsidiaries. Revenue at the insurance segment represents reinsurance premiums from third party insurance companies that provide insurance programs to BCO Independent Contractors where all or a portion of the risk is ultimately borne by Signature. Internal revenue for premiums billed by the insurance segment to the transportation logistics segment is calculated each fiscal period based primarily on an actuarial calculation of historical loss experience and is believed to approximate the cost that would have been incurred by the transportation logistics segment had similar insurance been obtained from an unrelated third party. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Company evaluates a segment’s performance based on operating income. No single customer accounted for more than 10% of the Company’s consolidated revenue in fiscal years 2022, 2021 and 2020. Substantially all of the Company’s revenue is generated in North America, primarily through customers located in the United States.

Change in Accounting Estimate for Self-Insured Claims	(14) Change in Accounting Estimate for Self-Insured Claims Landstar provides for the estimated costs of self-insured claims primarily on an actuarial basis. The amount recorded for the estimated liability for claims incurred is based upon the facts and circumstances known on the applicable balance sheet date. The ultimate resolution of these claims may be for an amount greater or less than the amount estimated by management. The Company continually revises its existing claim estimates as new or revised information becomes available on the status of each claim. Historically, the Company has experienced both favorable and unfavorable development of prior years’ claims estimates. The following table summarizes the adverse effect of the increase in the cost of insurance claims resulting from unfavorable development of prior year self-insured claims estimates on operating income, net income and earnings per share set forth in the consolidated statements of income for the fiscal years ended December 31, 2022, December 25, 2021 and December 26, 2020 (in thousands, except per share amounts): Fiscal Years Ended December 31, 2022 December 25, 2021 December 26, 2020 Operating income $ 11,331 $ 9,708 $ 9,196 Net income $ 8,570 $ 7,359 $ 6,989 Diluted earnings per share $ 0.23 $ 0.19 $ 0.18 The unfavorable development of prior years’ claims in the fiscal year ended December 31, 2022 was primarily attributable to several specific claims. The unfavorable development of prior years’ claims in the fiscal year ended December 25, 2021 was primarily attributable to five claims. The unfavorable development of prior years’ claims in the fiscal year ended December 26, 2020 was attributable to several specific claims as well as actuarially determined adjustments to prior year commercial trucking loss estimates.

Power-only refers to shipments where the Company furnishes a power unit and an operator but not trailing equipment, which is typically provided by the shipper or consignee.
Insurance Claim Costs	Insurance Claim Costs Landstar provides, primarily on an actuarially determined basis, for the estimated costs of cargo, property, casualty, general liability and workers’ compensation claims both reported and for claims incurred but not reported. For periods prior to May 1, 2019, Landstar retains liability for commercial trucking claims up to $5 million per occurrence and maintains various third party insurance arrangements for liabilities in excess of its $5 million self-insured retention. Effective May 1, 2019, the Company entered into a new three year commercial auto liability insurance arrangement for losses incurred between $5 million and $10 million (the “Initial Excess Policy”) with a third party insurance company. The Company subsequently extended the Initial Excess Policy for one additional policy year, from May 1, 2022 through April 30, 2023. For commercial trucking claims incurred on or after May 1, 2022 through April 30, 2023, the extended Initial Excess Policy provides for a limit for a single loss of $5 million, with a remaining aggregate limit of $10 million for the policy period ending April 30, 2023, and an option to increase such aggregate limit for a pre-established pre-established The Company also maintains third party insurance arrangements providing excess coverage for commercial trucking liabilities in excess of $10 million. These third party arrangements provide coverage on a per occurrence or aggregated basis. In recent years, the Company has increased the level of its financial exposure to commercial trucking claims in excess of $10 million, including through the use of additional self-insurance, deductibles, aggregate loss limits, quota shares and other arrangements with third party insurance companies, based on the availability of coverage within certain excess insurance coverage layers and estimated cost differentials between proposed premiums from third party insurance companies and historical and actuarially projected losses experienced by the Company at various levels of excess insurance coverage. Further, the Company retains liability of up to $1,000,000 for each general liability claim, up to $250,000 for each workers’ compensation claim and up to $250,000 for each cargo claim. In addition, under reinsurance arrangements by Signature of certain risks of the Company’s BCO Independent Contractors, the Company retains liability of up to $500,000, $1,000,000 or $2,000,000 with respect to certain occupational accident claims and up to $750,000 with respect to certain workers’ compensation claims.
Tires	Tires Tires purchased as part of trailing equipment are capitalized as part of the cost of the equipment. Replacement tires are charged to expense when placed in service.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Included in cash and cash equivalents are all investments, except those provided for collateral, with an original maturity of 3 months or less. At December 25, 2021, the Company had $4,049,000 of restricted cash held by the Company’s insurance segment included in the short-term investments balance of $35,778,000, providing collateral, along with certain other investments, for the letters of credit issued to guarantee payment of insurance claims.
Financial Instruments	Financial Instruments The Company’s financial instruments include cash equivalents, short and long-term investments, trade and other accounts receivable, accounts payable, other accrued liabilities, and long-term debt plus current maturities (“Debt”). The carrying value of cash equivalents, trade and other accounts receivable, accounts payable, current insurance claims and other accrued liabilities approximates fair value as the assets and liabilities are short term in nature. Short and long-term investments are carried at fair value as further described in Note 4 in the Company’s consolidated financial statements. The Company’s Debt includes borrowings under the Company’s revolving credit facility, to the extent there are any, plus borrowings relating to finance lease obligations used to finance trailing equipment. The interest rates on borrowings under the revolving credit facility are typically tied to short-term interest rates that adjust monthly and, as such, carrying value approximates fair value. Interest rates on borrowings under finance leases approximate the interest rates that would currently be available to the Company under similar terms and, as such, carrying value approximates fair value.
Trade and Other Receivables	Trade and Other Receivables The allowance for doubtful accounts for both trade and other receivables represents management’s estimate of the amount of outstanding receivables that will not be collected. Estimates are used to determine the allowance for doubtful accounts for both trade and other receivables and are generally based on specific identification, historical collection results, current economic trends and changes in payment trends.

The Company reviews its goodwill balance annually for impairment for each reporting unit, unless circumstances dictate more frequent assessments, and in accordance with ASU 2011-08, Testing Goodwill for Impairment 2011-08
Income Taxes	Income Taxes Income tax expense is equal to the current year’s liability for income taxes and a provision for deferred income taxes. Deferred tax assets and liabilities are recorded for the future tax effects attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates expected to be applied to taxable income in the years in which those temporary differences are expected to be recovered or settled.
Share-Based Payments	Share-Based Payments The Company’s share-based payment arrangements include restricted stock units (“RSU”), non-vested non-vested non-vested
Earnings Per Share	Earnings Per Share Earnings per common share are based on the weighted average number of shares outstanding, including outstanding non-vested non-vested For the fiscal years ended December 31, 2022, December 25, 2021 and December 26, 2020, no options outstanding to purchase shares of Common Stock were antidilutive. Outstanding RSUs were excluded from the calculation of diluted earnings per share for all periods because the performance metric requirements or market condition for vesting had not been satisfied.
