amended by ASU

2018-11,

Leases

(Topic 842):

Targeted Improvements

. ASU

2016-02

requires a company to recognize a

right-of-use

asset and lease liability for the obligation to make lease payments measured as the present value of the lease payments for all leases with terms greater than twelve months. The ASU requires adoption using a modified retrospective transition approach with either (1) periods prior to the adoption date being recast or (2) a cumulative-effect adjustment recognized to the opening balance of retained earnings on the adoption date with prior periods not recast. The Company adopted this standard on December 30, 2018 using the cumulative-effect adjustment approach. No cumulative-effect adjustment was recognized as the amount was not material. The Company had $2,745,000 in

right-of-use

assets and corresponding lease obligations as of December 28, 2019. See Note 9 for corresponding disclosures required under Topic 842.

(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 unfavorable development of prior years’ claims in the fiscal year ended December 29, 2018 was primarily attributable to five claims.

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

assets and operating lease liabilities represent leases for orientation centers for BCO Independent Contractors and office space used to conduct Landstar’s business. These leases do not have significant rent escalation holidays, concessions, leasehold improvement incentives or other

build-out

clauses. Further, the leases do not contain contingent rent provisions. Landstar also leases certain trailing equipment to supplement the Company-owned trailer fleet under

“month-to-month”

lease terms, which are not required to be recorded on the balance sheet due to the less than twelve month lease term exemption. Sublease income is primarily comprised of weekly trailing equipment rentals to our BCO Independent Contractors.

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

assets and lease liabilities as they are not reasonably certain of exercise. Landstar regularly evaluates the renewal options, and when they are reasonably certain of exercise, Landstar includes the renewal period in the lease term.

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, we apply a portfolio approach for determining the incremental borrowing rate.

Investments

(4) Investments

Investments include primarily investment-grade corporate bonds and U.S. Treasury obligations having maturities of up to five years (the “bond portfolio”) and money market investments. Investments in the bond portfolio are reported as

available-for-sale

and are carried at fair value. Investments maturing less than one year from the balance sheet date are included in short-term investments and investments maturing more than one year from the balance sheet date are included in other assets in the consolidated balance sheets. Management performs an analysis of the nature of the unrealized losses on

available-for-sale

investments to determine whether such losses are other-than-temporary. Unrealized losses, representing the excess of the purchase price of an investment over its fair value as of the end of a period, considered to be other-than-temporary, are to be included as a charge in the statement of income, while unrealized losses considered to be temporary are to be included as a component of equity. Investments whose values are based on quoted market prices in active markets are classified within Level 1. Investments that trade in markets that are not considered to be active, but are valued based on quoted market prices, are classified within Level 2. As Level 2 investments include positions that are not traded in active markets, valuations may be adjusted to reflect illiquidity and/or

non-transferability,

which are generally based on available market information. Any transfers between levels are recognized as of the beginning of any reporting period. Fair value of the bond portfolio was determined using Level 1 inputs related to U.S. Treasury obligations and money market investments and Level 2 inputs related to investment-grade corporate bonds, asset-backed securities and direct obligations of government agencies. Unrealized gains, net of unrealized losses, on the investments in the bond portfolio were $1,427,000 at December 28, 2019, while unrealized losses, net of unrealized gains, on the investments in the bond portfolio were $1,184,000 at December 29, 2018.

The amortized cost and fair values of

investments are as follows at December 28, 2019 and December 29, 2018 (in thousands):

The Company expects to recover 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, the Company does not consider the unrealized losses on these securities to be other-than-temporary at December 28, 2019.

Short-term investments include $32,770,000 in current maturities of investments and $131,000 of cash equivalents held by the Company’s insurance segment at December 29, 2018. The

non-current

portion of the bond portfolio of $84,838,000 is included in other assets. The short-term investments, together with $35,421,000 of

non-current

investments, provide collateral for the $61,503,000 of letters of credit issued to guarantee payment of insurance claims.

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.

At December 28, 2019, in addition to the $61,503,000 letters of credit secured by investments, Landstar had $34,368,000 of letters of credit outstanding under the Company’s Credit Agreement.

On January 25, 2019, a purported class action was filed in the Superior Court of the State of California for the County of San Bernardino against Landstar System, Inc. and Landstar Ranger, Inc. (together, the “Defendants”). The complaint purports to bring this action on behalf of Hany Tanious, as an individual, and “all owner operators who performed work for the Defendants, and who were classified as independent contractors, during the four years preceding the filing of this action through the present.” The complaint asserts claims based on the alleged misclassification of Mr. Tanious as an independent contractor and alleges violations under California law relating to overtime, minimum wage, meal and rest breaks, failure to reimburse certain expenses, wage statements, waiting time and unfair competition. Mr. Tanious was a truck owner-operator and formerly an independent contractor who was a party to an independent contractor operating agreement with Landstar Ranger, Inc. On June 11, 2019, the Defendants filed a Notice of Removal that resulted in the removal of the case from state court to federal court, where it was assigned to Judge Dale S. Fischer of the United State District Court for the Central District of California. On August 22, 2019, the Court issued an order, among other things, striking all class allegations from the complaint and stating that this matter would proceed as an individual action. Due to a number of factors including the preliminary status of this matter, the Company does not believe it is in a position to conclude whether or not there is a reasonable possibility of an adverse outcome in this case or what damages, if any, the plaintiff would be awarded should he prevail on all or any part of his claims. However, the Company believes it has meritorious defenses and it intends to assert these defenses vigorously.

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.

On December 22, 2017, the President of the United States signed into law the Tax Reform Act. The legislation significantly changed U.S. tax law by, among other things, lowering corporate income tax rates, implementing a territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. With respect to the change in corporate tax rates, the Tax Reform Act permanently reduced the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. In connection with this reduction in the U.S. corporate income tax rate, the Company revalued its ending net deferred tax liabilities at December 30, 2017 resulting in a provisional $20,430,000 tax benefit in the Company’s consolidated statement of income

for the fiscal year ended December 30, 2017. With respect to the repatriation tax on deemed repatriated earnings of foreign subsidiaries, the Tax Reform Act provided for a

one-time

deemed mandatory repatriation of post-1986 undistributed foreign subsidiary earnings and profits (“E&P”) through the fiscal year ended December 31, 2017. The Company had an estimated $17,981,000 of undistributed foreign E&P at the Company’s Canadian subsidiary, Landstar Canada, Inc., subject to the deemed mandatory repatriation and, accordingly, recognized a provisional $900,000 of income tax expense in the Company’s consolidated statement of income for the fiscal year ended December 30, 2017. After the utilization of existing tax credits, the Company paid U.S. federal cash taxes of approximately $500,000 on the deemed mandatory repatriation in 2018.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. The Company recognized the provisional tax impacts related to deemed repatriated earnings and the revaluation of deferred tax assets and liabilities and included these amounts in its consolidated financial statements for the fiscal year ended December 30, 2017. The accounting was complete when the 2017 U.S. corporate income tax return was filed in 2018 and no significant adjustments were made to the previously recognized provisional amounts.

Also during fiscal year 2017, the Company adopted ASU

2016-09.

As required by ASU

2016-09,

the Company recognized $3,019,000, $2,060,000 and $1,299,000 of excess tax benefits on stock-based awards in its provision for income taxes in the 2019, 2018 and 2017 fiscal years, respectively.

The Company files a consolidated U.S. federal income tax return. The Company or its subsidiaries file state tax returns in the majority of the U.S. state tax jurisdictions. With few exceptions, the Company and its subsidiaries are no longer subject to U.S. federal or state income tax examinations by tax authorities for 2015 and prior years. The Company’s wholly owned Canadian subsidiary, Landstar Canada, Inc., is subject to Canadian income and other taxes. The Company’s wholly owned Mexican subsidiaries, Landstar Holdings, S. de R.L.C.V., Landstar Metro, S.A.P.I. de C.V. and Landstar Metro Servicios S.A.P.I. de C.V. are subject to Mexican and U.S. income and other taxes.

As of December 28, 2019 and December 29, 2018, the Company had $2,253,000 and $2,403,000, respectively, of net unrecognized tax benefits representing the provision for the uncertainty of certain tax positions plus a component of interest and penalties. Estimated interest and penalties on the provision for the uncertainty of certain tax positions is included in income tax expense. At December 28, 2019 and December 29, 2018 there was $690,000 and $653,000, respectively, accrued for estimated interest and penalties related to the uncertainty of certain tax positions. The Company does not currently anticipate any significant increase or decrease to the unrecognized tax benefit during fiscal year 2020.

Debt

(8) Debt

Other than the

finance

lease obligations as presented on the consolidated balance sheets, the Company had

outstanding debt as of December 28, 2019 and December 29, 2018.

June 2, 2016

, Landstar entered into a credit agreement with a syndicate of banks and JPMorgan Chase Bank, N.A., as administrative agent (the “Credit Agreement”). The Credit Agreement, which matures on

June 2, 2021

, provides $250,000,000 of borrowing capacity in the form of a revolving credit facility, $50,000,000 of which may be utilized in the form of letter of credit

guarantees. The Credit Agreement includes an “accordion” feature providing for a possible increase up to an aggregate borrowing amount of $

400,000,000

. The Company’s prior credit agreement was terminated on June

2016

. Borrowings under the Credit Agreement are unsecured, however, all but four of the Company’s U.S. subsidiaries guarantee the obligations under the Credit Agreement along with Signature Insurance Company. On February

2018

Landstar

entered into an amendment to the Credit Agreement whereby

Landstar

Canada Holdings, Inc., the U.S. parent of

Landstar

Canada, and

Landstar

MH I, LLC, the U.S. parent of

Landstar

Holdings, S. de R.L.C.V.,

Landstar

Metro and

Landstar

Servicios

, in lieu of providing a guarantee of the obligations under the Credit Agreement, granted to the administrative agent, for the benefit of the bank syndicate, a first-priority, perfected pledge and security interest in

% of each series of its outstanding voting capital stock and

100

% of each series of its outstanding

non-voting

capital stock. Any future amounts that may become outstanding under the Credit Agreement are payable on June

2021

, the maturity date of the Credit Agreement.

Depending upon the specific type of borrowing, borrowings under the Credit Agreement bear interest based on either (a) the prime rate, (b) the Federal Reserve Bank of New York rate plus 0.5% or (c) the London Interbank Offered Rate, plus 1.25%. The unused portion of the revolving credit facility under the Credit Agreement carries a commitment fee determined based on the level of the Leverage Ratio. The commitment fee for the unused portion of the revolving credit facility under the Credit Agreement ranges

from .15% to .25%, based

on achieving certain levels of the Leverage Ratio. As of December 28, 2019 and December 29, 2018, the Company had

borrowings outstanding under the Credit Agreement.

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 defined 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 to 1 on a pro forma basis as of the end of the Company’s most recently completed fiscal quarter. The Credit Agreement provides for an event of default in the event that, among other things, a person or group acquires 35% or more of the outstanding capital stock of the Company or obtains power to elect a majority of the Company’s directors or the directors cease to consist of a majority of Continuing Directors, as defined in the Credit Agreement. None of these covenants are presently considered by management to be materially restrictive to the Company’s operations, capital resources or liquidity.

The Company is currently in compliance with all of the debt covenants under the Credit Agreement.

The

interest

rates on borrowings under the revolving credit facility are typically tied to short-term LIBOR 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.

Landstar paid interest of $4,439,000 in fiscal year 2019, $3,761,000 in fiscal year 2018 and $3,891,000 in fiscal year 2017.

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

and delivery of a customer’s freight on a

shipment-by-shipment

basis. Landstar customers are typically invoiced on a

shipment-by-shipment

basis at a

pre-defined

rate, payable thirty to sixty

(30-60)

days after the customer’s receipt of such invoice. Payment terms to customers do not contain a significant financing component and the amount owed by the customer does not contain variable terms, embedded or otherwise. We have determined that revenue recognition over the freight transit period provides a faithful depiction of the transfer of services to the customer as our obligation for which we are primarily responsible for fulfilling is performed over the transit period. Accordingly, transportation revenue billed to a customer for the physical transportation of freight and related direct freight expenses are recognized on a gross basis over the freight transit period as the performance obligation to the customer is satisfied. The Company determines the transit period for a given shipment based upon the

pick-up

date and the delivery date, which may be estimated if delivery has not occurred as of the reporting date. Determining the transit period and how much of it has been completed as of a given reporting date may therefore require management to make judgments that affect the timing of revenue recognized. With respect to shipments with a

pick-up

date in one reporting period and a delivery date in another, the Company recognizes such transportation revenue based on relative transit time in each reporting period. A days in transit output method is used to measure the progress of the performance of the Company’s freight transportation services as of the reporting date and a portion of the total revenue that will be billed to the customer once a load is delivered is recognized in each reporting period based on the percentage of total transit time that has been completed at the end of the applicable reporting period. Reinsurance premiums of the insurance segment are recognized over the period earned, which is usually on a monthly basis. Fuel surcharges billed to customers for freight hauled by independent contractors who provide truck capacity to the Company under exclusive lease arrangements (the “BCO Independent Contractors”) are excluded from revenue and paid in entirety to the BCO Independent Contractors.

Adoption of Topic 606, "Revenue from Contracts with Customers

Adoption of Topic 606, “Revenue from Contracts with Customers”

The Company adopted Accounting Standards Update

2014-09

– Revenue from Contracts with Customers (“ASU

2014-09”)

on December 31, 2017 under the modified retrospective transition method resulting in a $773,000 cumulative adjustment to retained earnings. Our reported results for 2019 and 2018 are presented under Topic 606, while our prior periods were not adjusted and are reported under Topic 605 “Revenue Recognition.”

Revenue from Contracts with Customers - Disaggregation of Revenue

During the fiscal year ended December 28, 2019, revenue generated by BCO Independent Contractors, Truck Brokerage Carriers and railroads represented approximately 45%, 47% and 3% respectively, of the Company’s consolidated revenue. Collectively, revenue generated by air and ocean cargo carriers represented approximately 3% of the Company’s consolidated revenue in the fiscal

year ended December 28, 2019.

Included

in truck transportation revenue generated by BCO Independent Contractors and Truck Brokerage Carriers during the fiscal year ended December 28, 2019 was $2,371,188,000 hauled via van equipment, $1,295,817,000 hauled via unsided/platform equipment and $98,324,000 of less-than-truckload.

During the fiscal year ended December 29, 2018, revenue generated by BCO Independent Contractors, Truck Brokerage Carriers and railroads represented approximately 43%, 49% and 3%, respectively, of the Company’s consolidated revenue. Collectively, revenue generated by air and ocean cargo carriers represented approximately 3% of the Company’s consolidated revenue in the fiscal year ended December 29, 2018. Included in truck transportation revenue generated by BCO Independent Contractors and Truck Brokerage Carriers during the fiscal year ended December 29, 2018 was $2,791,494,000 hauled via van equipment, $1,386,387,000 hauled via unsided/platform equipment and $102,531,000 of less-than-truckload.

Collectively, revenue generated by air and ocean cargo carriers represented approximately 3% of the Company’s consolidated revenue in the fiscal year ended December 30, 2017. Included in truck transportation revenue generated by BCO Independent Contractors and Truck Brokerage Carriers during the fiscal year ended December 30, 2017 was $2,163,832,000 hauled via van equipment, $1,134,660,000 hauled via unsided/platform equipment and $89,041,000 of less-than-truckload.

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 $5,000,000 per occurrence and maintains various third party insurance arrangements for liabilities in excess of its $5,000,000 self-insured retention. Effective May 1, 2019, the Company entered into a new three year commercial auto liability insurance arrangement for losses incurred between $5,000,000 and $10,000,000 (the “Initial Excess Policy”) with a third party insurance company. For commercial trucking claims incurred on or after May 1, 2019 through April 30, 2022, the Initial Excess Policy provides for a limit for a single loss of $5,000,000, with an aggregate limit of $10,000,000 for each policy year, an aggregate limit of $15,000,000 for the

thirty-six

month term ended April 30, 2022, and options to increase such aggregate limits for

pre-established

amounts of additional premium. In the event paid aggregate losses under the Initial Excess Policy during any policy year (May 1 to April 30) exceed $10,000,000, the Company would retain liability of up to $10,000,000 per occurrence, inclusive of its $5,000,000 self-insured retention, for the remainder of such policy year. Moreover, in the event paid aggregate losses under the Initial Excess Policy during the three year period ending April 30, 2022 exceed a

pre-determined

threshold amount, the Company would be required to pay additional premium up to a maximum amount of $3,500,000.

As previously disclosed, BCO Independent Contractors with a subsidiary of the Company have been involved in two tragic accidents during the policy year ending April 30, 2020, the first of which occurred in the 2019 third quarter and the second of which occurred in the 2020 first quarter. With respect to the second accident, the Company is still in the process of obtaining all the facts concerning this incident and, as such, it is too soon to estimate the Company’s ultimate financial exposure. The Company’s

pre-tax

loss exposure at the time of the second accident included its $5,000,000 self-insured retention and up to $3,500,000 in additional premium relating to aggregate losses above its self-insured retention during the policy year ending April 30, 2020. If, as a result of these or additional accidents, aggregate losses under the Initial Excess Policy during the policy year ending April 30, 2020 exceed $10,000,000, Landstar would retain liability of up to $10,000,000 per occurrence, inclusive of its self-insured retention for commercial trucking claims during the remainder of such policy year.

The Company continues to maintain third party insurance arrangements providing excess coverage on a per occurrence basis for commercial trucking

liabilities in excess of $

10,000,000

The Company also 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 and Cash Equivalents

Included in cash and cash equivalents are all investments, except those provided for collateral, with an original maturity of 3 months or less.

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 LIBOR 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 28, 2019, December 29, 2018 and December 30, 2017 (in thousands):


	Balance at Beginning of Period		Charged to Costs and Expenses		Write-offs, Net of Recoveries			Balance at End of Period

Operating Property

Operating property is recorded at cost. Depreciation is provided on a straight-line basis over the estimated useful lives of the related assets. Buildings and improvements are being depreciated over 30 years. Trailing equipment is being depreciated over 7 to 10 years. Information technology hardware and software included in other equipment is generally being depreciated over 3 to 7 years.

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

. ASU

2011-08

permits an initial assessment, commonly referred to as “step zero”, of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount and also provides a basis for determining whether it is necessary to perform the quantitative analysis required by ASC Topic 350. In

the fourth fiscal quarter of 2019, the Company performed the qualitative assessment of goodwill and determined it was more likely than not that the fair value of each of its reporting units would be greater than its carrying amount. Therefore, the Company determined it was not necessary to perform the quantitative goodwill impairment test. Furthermore, there has been no historical impairment of the Company’s goodwill.

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. On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (the “Tax Reform Act”). Further information on the tax impacts of the Tax Reform Act is included in Note 5 of the Company’s consolidated financial statements.

Share-Based Payments

The Company’s share-based payment arrangements include restricted stock units (“RSU”), stock options,

non-vested

restricted stock and Deferred Stock Units. The fair value of an RSU with a performance condition is determined based on the market value of the Company’s Common Stock on the date of grant, discounted for lack of marketability for a minimum post-vesting holding requirement. With respect to RSU awards with a performance condition, the Company reports compensation expense ratably over the life of the award based on an estimated number of units that will vest over the life of the award, multiplied by the fair value of an RSU. The fair value of an RSU with a market condition is determined at the time of grant based on the expected achievement of the market condition at the end of each vesting period. With respect to RSU awards with a market condition, the Company recognizes compensation expense ratably over the requisite service period under an award based on the fair market value of the award at the time of grant, regardless of whether the market condition is satisfied. Previously recognized compensation cost would be reversed, however, if the employee terminated employment prior to completing such requisite service period. The Company estimates the fair value of stock option awards on the date of grant using the Black-Scholes pricing model and recognizes compensation cost for stock option awards expected to vest on a straight-line basis over the requisite service period for the entire award. Forfeitures are estimated at grant date based on historical experience and anticipated employee turnover. The fair values of each share of

non-vested

restricted stock issued and Deferred Stock Unit granted are based on the fair value of a share of the Company’s Common Stock on the date of grant and compensation costs for

non-vested

restricted stock and Deferred Stock Units are recognized on a straight-line basis over the requisite service period for the award.

Earnings Per Share

Earnings per common share attributable to Landstar System, Inc. and subsidiary are based on the weighted average number of shares outstanding, including outstanding

non-vested

restricted stock and outstanding Deferred Stock Units. Diluted earnings per share attributable to Landstar System, Inc. and subsidiary are based on the weighted average number of common shares and Deferred Stock Units outstanding plus the incremental shares that would have been outstanding upon the assumed exercise of all dilutive stock options.

The following table provides a reconciliation of the average number of common shares outstanding used to calculate earnings per common share attributable to Landstar System, Inc. and subsidiary to the average number of common shares and common share equivalents outstanding used to calculate diluted earnings per share attributable to Landstar System, Inc. and subsidiary (in thousands):


	Fiscal Years
	2019		2018		2017
Average number of common shares outstanding		39,786		41,273		41,938
Incremental shares from assumed exercises of stock options		—		37		86

Average number of common shares and common share equivalents outstanding		39,786		41,310		42,024

For the fiscal years ended December 28, 2019, December 29, 2018 and December 30, 2017,

options outstanding to purchase shares of Common Stock were antidilutive. Outstanding RSUs were excluded from the calculation of diluted earnings per share attributable to Landstar System, Inc. and subsidiary for all periods because the performance metric requirements or market condition for vesting had not been satisfied.

Dividends Payable

On December 10, 2019, the Company announced that its Board of Directors declared a special cash dividend of $2.00 per share payable on January 24, 2020, to stockholders of record of its Common Stock as of January 10, 2020. Dividends payable of $78,947,000 related to this special dividend were included in current liabilities in the consolidated balance sheet at December 28, 2019.

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.

Segment Information

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

contractual arrangements (the “Truck Brokerage Carriers”), air cargo carriers, ocean cargo carriers and railroads. Through this network of agents and capacity providers linked together by Landstar’s information technology systems, Landstar operates an integrated transportation management solutions business primarily throughout North America with revenue of $4.1 billion during the most recently completed fiscal year. The Company reports the results of two operating segments: the transportation logistics segment and the insurance segment.

The transportation logistics segment provides a wide range of integrated transportation management solutions. Transportation services offered by the Company include truckload and less-than-truckload 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 products, 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. Each of the independent commission sales agents has the opportunity to market all of the 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 Metro and Landstar Servicios 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 2019, 2018 and 2017. Substantially all of the Company’s revenue is generated in North America, primarily through customers located in the United States.

Share-Based Payment Arrangements

(10) Share-Based Payment Arrangements

As of December 28, 2019, the Company had

two

employee equity incentive plans, the 2002 employee stock option and stock incentive plan (the “ESOSIP”) and the 2011 equity incentive plan (the “2011 EIP”). No further grants can be made under the ESOSIP. The Company also has a stock compensation plan for members of its Board of Directors, the Amended and Restated 2013 Directors Stock Compensation Plan (as amended and restated as of May 17, 2016, the “2013 DSCP”). 6,000,000 shares of the Company’s Common Stock were authorized for issuance under the 2011 EIP and 115,000 shares of the Company’s Common Stock were authorized for issuance under the 2013 DSCP. The ESOSIP, 2011 EIP and 2013 DSCP are each referred to herein as a “Plan,” and, collectively, as the “Plans.” Amounts recognized in the financial statements with respect to these Plans are as follows (in thousands):


	Fiscal Years

As of December 28, 2019, there were 66,454 shares of the Company’s Common Stock reserved for issuance under the 2013 DSCP and 3,959,718 shares of the Company’s Common Stock reserved for issuance in the aggregate under the ESOSIP and 2011 EIP.

Restricted Stock Units

The following table summarizes information regarding the Company’s outstanding restricted stock unit (“RSU”) awards with either a performance condition or a market condition under the Plans:

During fiscal years 2017, 2018 and 2019 the Company granted RSUs with a performance condition. During fiscal years 2018 and 2019, the Company also issued RSUs with a market condition, as further described below.

RSUs with a performance condition granted on February 1, 2019 may vest on January 31 of 2022, 2023 and 2024. RSUs with a performance condition granted on February 2, 2018 may vest on January 31 of 2021, 2022 and 2023. RSUs with a performance condition granted on February 2, 2017 may vest on January 31 of 2020, 2021 and 2022. RSUs with a performance condition granted on February 1, 2019 and February 2, 2018 vest based on growth in operating income and

pre-tax

income per diluted share from continuing operations attributable to Landstar System, Inc. and subsidiary as compared to a base year, being the year immediately preceding the year of grant. RSUs with a performance condition granted on February 2, 2017 vest based on growth in operating income and diluted earnings per share from continuing operations attributable to Landstar System, Inc. and subsidiary as compared to a base year, being the year immediately preceding the year of grant. At the time of grant, the target number of common shares available for issuance under the February 1, 2019, February 2, 2018 and February 2, 2017 grants equals 100% of the number of RSUs granted, and the maximum number of common shares available for issuance under the February 1, 2019, February 2, 2018 and February 2, 2017 grants equals 200% of the number of RSUs credited to the recipient. In the event actual results exceed the target, the number of shares that will be granted will exceed the number of RSUs granted. The fair value of an RSU with a performance condition was determined based on the market value of the Company’s Common Stock on the date of grant, discounted for lack of marketability for a minimum post-vesting holding requirement. The discount rate due to lack of marketability used for RSU award grants with a performance condition for all periods was 7%. With respect to RSU awards with a performance condition, the Company reports compensation expense over the life of the award based on an estimated number of units that will vest over the life of the award, multiplied by the fair value of an RSU at the time of grant.

During fiscal year 2019, the Company granted 9,725 RSUs that vest based on a market condition. During fiscal year 2018, the Company granted 9,324 RSUs that vest based on a market condition. The RSUs granted in 2019 may vest on June 30 of 2023, 2024 and 2025, and the RSUs granted in 2018 may vest on June 30 of 2022, 2023 and 2024, in each case based on the Company’s total shareholder return (“TSR”) compound annual growth rate over the vesting periods, adjusted to reflect dividends (if any) paid during such periods and capital adjustments as may be necessary. The maximum number of common shares available for issuance under each grant equals 150% of the number of RSUs granted. The fair value of each RSU award was determined at the time of grant based on

the expected achievement of the market condition at the end of each vesting period. With respect to these RSU awards, the Company reports compensation expense ratably over the life of the award based on an estimated number of units that will vest over the life of the award, multiplied by the fair value of the RSU. Previously recognized compensation cost would be reversed only if the employee terminated employment prior to completing the requisite service period.

The Company recognized approximately $1,557,000, $15,985,000 and $5,849,000 of share-based compensation expense related to RSU awards in fiscal years 2019, 2018 and 2017, respectively. As of December 28, 2019, there was a maximum of $27.4 million of total unrecognized compensation cost related to RSU awards granted under the Plans with an expected average remaining life of approximately 3.0 years. 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.

Stock Options

The Company did not grant any stock options during its 2017, 2018 or 2019 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:

At December 28, 2019, the total intrinsic value of options outstanding and exercisable was $2,754,000. The total intrinsic value of stock options exercised during fiscal years 2019, 2018 and 2017 was $2,683,000, $6,715,000 and $7,599,000, respectively.

As of December 28, 2019, there was no unrecognized compensation cost related to

non-vested

stock options granted under the Plans.

Non-vested

Restricted Stock and Deferred Stock Units

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

restricted stock and Deferred Stock Units (defined below) under the Plans:


	Number of Shares and Deferred Stock Units			Weighted Average Grant Date Fair Value
Non-vested at December 31, 2016		28,409		$	58.91
Granted		42,573		$	84.47
Vested		(16,227	)	$	61.50

Non-vested at December 30, 2017		54,755		$	78.02
Granted		22,803		$	113.35
Vested		(19,814	)	$	75.11
Forfeited		(1,757	)	$	71.12

Non-vested at December 29, 2018		55,987		$	93.66
Granted		30,338		$	102.76
Vested		(21,517	)	$	92.70

Non-vested at December 28, 2019		64,808		$	98.24

The fair value of each share of

non-vested

restricted stock issued and Deferred Stock Unit granted under the Plans is based on the fair value of a share of 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 2013 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 28, 2019, there was $3,623,000 of total unrecognized compensation cost related to

non-vested

shares of restricted stock and Deferred Stock Units granted under the Plans. The unrecognized compensation cost related to these

non-vested

shares of restricted stock and Deferred Stock Units is expected to be recognized over a weighted average period of 2.0 years.

Directors’ Stock Compensation Plan

Directors of the Company who are not employees of the Company (each an “Eligible Director”) are 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 $110,000 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”). In fiscal year 2019, 5,240 restricted shares and 1,048 Deferred Stock Units were granted to Eligible Directors. In fiscal year 2018, 4,950 restricted shares and 990 Deferred Stock Units were granted to Eligible Directors. In fiscal year 2017, 6,575 restricted shares and 1,315 Deferred Stock Units were granted to Eligible Directors. Restricted shares and Deferred Stock Units granted in 2017, 2018 and 2019 vest on the date of the next Annual Meeting. During fiscal years 2019, 2018 and 2017, $660,000, $660,000 and $651,000, respectively, of compensation cost was recorded for the grant of these restricted shares and Deferred Stock Units.

Acquired Business and Noncontrolling Interests

(2) Acquired Business and Noncontrolling Interests

During 2017, the Company incorporated each of Landstar Metro and Landstar Servicios. On September 20, 2017, Landstar Metro acquired substantially all of the assets (the “Mexican Asset Acquisition”) of the asset-light transportation logistics business of Fletes Avella, S.A. de C.V., a Mexican transportation logistics company (“Fletes Avella”). Cash consideration paid in fiscal year 2017 for the Mexican Asset Acquisition was approximately $8,460,000. At December 30, 2017, there was approximately $1,900,000 in liabilities outstanding consisting of additional contingent purchase price and associated indirect taxes of which approximately $1,000,000 was remitted during the 2018 fiscal year and approximately $900,000 was negated in connection with the settlement of certain purchase price penalties relating to post-closing operating commitments of Fletes Avella to Landstar Metro. In connection with the Mexican Asset Acquisition, individuals affiliated with the seller subscribed in the aggregate for equity interests in Landstar Metro and Landstar Servicios, and, as of December 29, 2018, owned in the aggregate approximately 21% of the equity interests of each of them. The Mexican Asset Acquisition was accounted for as a business combination in accordance with Accounting Standards Codification 805, Business Combinations (“ASC 805”). The resulting goodwill arising from the acquisition was approximately $7,900,000 as of December 28, 2019, and following the purchase of the noncontrolling interests by the Company, 100% of this goodwill is deductible by the Company. Pro forma financial information for prior periods is not presented as the Company does not believe the Mexican Asset Acquisition to be material to consolidated results. The results of operations from Landstar Metro and Landstar Servicios are presented as part of the Company’s transportations logistics segment. During the fiscal year ended December 30, 2017, the Company incurred approximately $1,000,000, or $0.01 per common share ($0.01 per diluted share), in

one-time

costs related to the completion of the acquisition and subscription of the

non-controlling

interests.

As it relates to the noncontrolling interests of Landstar Metro and Landstar Servicios, on August 10, 2018, Landstar acquired approximately 9% of each of Landstar Metro and Landstar Servicios from the minority equityholders in connection with the settlement of certain penalties relating to post-closing operating commitments of Fletes Avella to Landstar Metro. In connection with the settlement of several matters relating to the wind-down of the commercial relationship between Fletes Avella, its owners and Landstar Metro, on January 29, 2019, Landstar acquired all of the remaining equity interests in Landstar Metro and Landstar Servicios held by their former minority equityholders. Accordingly, as of such date, Landstar Metro and Landstar Servicios each became wholly owned subsidiaries of the Company. Cash consideration paid in the 2019 fiscal year to purchase these remaining equity interests was $600,000.
