LANDSTAR SYSTEM, INC. AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

The consolidated financial statements include the accounts of Landstar System, Inc. and its subsidiary, Landstar System Holdings, Inc., and reflect all adjustments (all of a normal, recurring nature) which are, in the opinion of management, necessary for a fair statement of the results for the periods presented. The preparation of the consolidated financial statements requires the use of management’s estimates. Actual results could differ from those estimates. Landstar System, Inc. and its subsidiary are herein referred to as “Landstar” or the “Company.” Significant intercompany accounts have been eliminated in consolidation.

Landstar owns, through various subsidiaries, a controlling interest in Landstar Metro, S.A.P.I. de C.V., a transportation logistics company (“Landstar Metro”), and Landstar Metro Servicios S.A.P.I. de C.V., a services company (“Landstar Servicios”), each based in Mexico City, Mexico. Given Landstar’s controlling interest in each of Landstar Metro and Landstar Servicios, the accounts of Landstar Metro and Landstar Servicios have been consolidated herein and a noncontrolling interest has been recorded for the noncontrolling investors’ interests in the net assets and operations of Landstar Metro and Landstar Servicios.

(1) 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 of the asset-light transportation logistics business of Fletes Avella, S.A. de C.V., a Mexican transportation logistics company. At March 31, 2018 and December 30, 2017, there was approximately $700,000 and $1,900,000, respectively, in liabilities outstanding consisting of additional contingent purchase price and associated indirect taxes. In connection with the acquisition, individuals affiliated with the seller subscribed in the aggregate for a 30% equity interest in each of Landstar Metro and Landstar Servicios. The asset acquisition by Landstar Metro 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 $8,500,000 as of March 31, 2018. With respect to this goodwill, 70% is expected to be deductible by the Company for U.S. income tax purposes, and following a purchase of the noncontrolling interests by the Company, up to 100% of this goodwill would be expected to be deductible by the Company. Pro forma financial information for prior periods is not presented as the Company does not believe the acquisition to be material to our consolidated results. The results of operations from Landstar Metro and Landstar Servicios are presented as part of the Company’s transportations logistics segment.

As it relates to the noncontrolling interests of Landstar Metro and Landstar Servicios, the Company has the option to purchase, and the minority equityholders have the option to sell, during the period commencing on the third anniversary of September 20, 2017, the closing date of the subscription by the minority equityholders (the “Closing Date”), and at any time after the fourth anniversary of the Closing Date, at fair value all but not less than all of the noncontrolling interests in Landstar Metro and Landstar Servicios. The noncontrolling interests are also subject to customary restrictions on transfer, including a right of first refusal in favor of the Company.

(2) Share-based Payment Arrangements

As of March 31, 2018, 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.

9

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):

	Thirteen Weeks Ended
	March 31, 2018			April 1, 2017
Total cost of the Plans during the period	$	3,710		$	994
Amount of related income tax benefit recognized during the period		(2,251	)		(1,127	)
Net cost of the Plans during the period	$	1,459		$	(133	)

Included in income tax benefits recognized in the thirteen-week periods ended March 31, 2018 and April 1, 2017 were income tax benefits of $50,000 and $221,000, respectively, recognized on disqualifying dispositions of the Company’s common stock by employees who obtained shares of common stock through exercises of incentive stock options. Also included in income tax benefits recognized in the thirteen-week periods ended March 31, 2018 and April 1, 2017 were excess tax benefits from stock-based awards of $1,298,000 and $563,000, respectively.

As of March 31, 2018, there were 78,682 shares of the Company’s common stock reserved for issuance under the 2013 DSCP and 4,519,920 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:

	Number of			Weighted Average Grant Date
	RSUs			Fair Value
Outstanding at December 30, 2017		387,372		$	55.75
Granted		55,651		$	103.47
Vested		(67,971	)	$	53.92
Forfeited		(92,880	)	$	52.36
Outstanding at March 31, 2018		282,172		$	66.72

During the thirteen-week period ended March 31, 2018, the Company granted RSUs with a performance condition. RSUs with a performance condition granted on February 2, 2018 may vest on January 31 of 2021, 2022 and 2023 based on growth in operating income and pre-tax income per share from continuing operations attributable to Landstar System, Inc. and subsidiary as compared to the results from the 2017 fiscal year. Outstanding RSUs at both December 30, 2017 and March 31, 2018 include RSUs with a performance condition and RSUs with a market condition, as further described in the Company’s 2017 Annual Report on Form 10-K.

The Company recognized approximately $3,153,000 and $524,000 of share-based compensation expense related to RSU awards in the thirteen-week periods ended March 31, 2018 and April 1, 2017, respectively. As of March 31, 2018, there was a maximum of $30.2 million of total unrecognized compensation cost related to RSU awards granted under the Plans with an expected average remaining life of approximately 3.5 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.

10

Stock Options

The following table summarizes information regarding the Company’s outstanding stock options under the Plans:

						Weighted Average
	Number of			Weighted Average Exercise Price		Remaining Contractual		Aggregate Intrinsic
	Options			per Share		Term (years)		Value (000s)
Options outstanding at December 30, 2017		189,040		$	49.34
Exercised		(40,418	)	$	48.42
Options outstanding at March 31, 2018		148,622		$	49.59		3.7	$	8,927
Options exercisable at March 31, 2018		147,622		$	49.53		3.7	$	8,875

The total intrinsic value of stock options exercised during the thirteen-week periods ended March 31, 2018 and April 1, 2017 was $2,463,000 and $3,620,000, respectively.

As of March 31, 2018, 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 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 30, 2017		54,755		$	78.02
Granted		16,863		$	114.13
Vested		(9,819	)	$	65.27
Forfeited		(1,757	)	$	71.12
Non-vested at March 31, 2018		60,042		$	90.45

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 the grant or the third, fourth and fifth anniversary of the date of the grant, or 100% on the first 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 will 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 March 31, 2018, there was $4,236,000 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 2.9 years.

(3) Income Taxes

The Tax Cuts and Jobs Act (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. The provisions for income taxes for the 2018 and 2017 thirteen-week periods were based on estimated annual effective income tax rates of 24.5% and 38.2%, respectively, adjusted for discrete events, such as benefits resulting from stock-based awards. The applicable effective income tax rates for the 2018 and 2017 thirteen-week periods were 22.7% and 36.8%, respectively, which were higher than the applicable statutory federal income tax rates of 21% and 35%, respectively. The increase as

11

compared to the statutory federal income tax rate for the 2018 thirteen-week period was primarily attributable to state taxes, the elimination of the performance-based exception under Section 162(m) included in the Tax Reform Act and the meals and entertainment exclusion, partially offset by excess tax benefits realized on stock based awards. The increase as compared to the statutory federal income tax rate for the 2017 thirteen-week period was primarily attributable to state taxes, the meals and entertainment exclusion and non-deductible stock-based compensation, partially offset by excess tax benefits realized on stock based awards and income tax benefits recognized on disqualifying dispositions on the Company’s common stock.

(4) 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):

	Thirteen Weeks Ended
	March 31, 2018		April 1, 2017
Average number of common shares outstanding		42,038		41,879
Incremental shares from assumed exercises of stock options		60		119
Average number of common shares and common share equivalents outstanding		42,098		41,998

For each of the thirteen-week periods ended March 31, 2018 and April 1, 2017, no 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.

(5) Additional Cash Flow Information

During the 2018 thirteen-week period, Landstar paid income taxes and interest of $464,000 and $976,000, respectively.

(7) Other Comprehensive Income

The following table presents the components of and changes in accumulated other comprehensive income attributable to Landstar System, Inc. and subsidiary, net of related income taxes, as of and for the thirteen-week period ended March 31, 2018 (in thousands):

	Unrealized Holding Losses on  Available-for- Sale Securities			Foreign Currency Translation			Total
Balance as of December 30, 2017	$	(144	)	$	(3,018	)	$	(3,162	)
Other comprehensive (loss) income		(730	)		341			(389	)
Balance as of March 31, 2018	$	(874	)	$	(2,677	)	$	(3,551	)

Amounts reclassified from accumulated other comprehensive income to investment income due to the realization of previously unrealized gains and losses in the accompanying consolidated statements of income were not significant for the thirteen-week period ended March 31, 2018.

(8) Investments

Investments include primarily investment-grade corporate bonds 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 money market investments and Level 2 inputs related to investment-grade corporate bonds, asset-backed securities and direct obligations of government agencies. Unrealized losses, net of unrealized gains, on the investments in the bond portfolio were $1,113,000 and $223,000 at March 31, 2018 and December 30, 2017, respectively.

The amortized cost and fair values of available-for-sale investments are as follows at March 31, 2018 and December 30, 2017 (in thousands):

			Gross		Gross
	Amortized Cost		Unrealized Gains		Unrealized Losses		Fair Value
March 31, 2018
Money market investments	$	26,096	$	—	$	—	$	26,096
Asset-backed securities		1,878		—		8		1,870
Corporate bonds and direct obligations of government agencies		83,764		25		1,130		82,659
Total	$	111,738	$	25	$	1,138	$	110,625
December 30, 2017
Money market investments	$	27,895	$	—	$	—	$	27,895
Asset-backed securities		2,805		—		5		2,800
Corporate bonds and direct obligations of government agencies		80,442		117		335		80,224
Total	$	111,142	$	117	$	340	$	110,919

For those available-for-sale investments with unrealized losses at March 31, 2018 and December 30, 2017, the following table summarizes the duration of the unrealized loss (in thousands):

	Less than 12 months				12 months or longer				Total
	Fair Value		Unrealized Loss		Fair Value		Unrealized Loss		Fair Value		Unrealized Loss
March 31, 2018
Asset-backed securities	$	1,870	$	8	$	—	$	—	$	1,870	$	8
Corporate bonds and direct obligations of government agencies		65,717		953		9,931		177		75,648		1,130
Total	$	67,587	$	961	$	9,931	$	177	$	77,518	$	1,138
December 30, 2017
Asset-backed securities	$	1,864	$	4	$	632	$	1	$	2,496	$	5
Corporate bonds and direct obligations of government agencies		41,322		220		14,016		115		55,338		335
Total	$	43,186	$	224	$	14,648	$	116	$	57,834	$	340

The Company believes unrealized losses on investments were primarily caused by rising interest rates rather than changes in credit quality. 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 March 31, 2018.

(9) Commitments and Contingencies

Short-term investments include $39,014,000 in current maturities of investments held by the Company’s insurance segment at March 31, 2018. The non-current portion of the bond portfolio of $71,611,000 is included in other assets. The short-term investments, together with $28,970,000 of non-current investments, provide collateral for the $61,186,000 of letters of credit issued to guarantee payment of insurance claims. As of March 31, 2018, Landstar also had $33,115,000 of additional letters of credit outstanding under the Company’s Credit Agreement.

During 2017, the Company incorporated each of Landstar Metro and Landstar Servicios. On September 20, 2017, Landstar Metro acquired substantially all of the assets of the asset-light transportation logistics business of Fletes Avella, S.A. de C.V., a Mexican transportation logistics company. In connection with the acquisition, individuals affiliated with the seller subscribed in the aggregate for a 30% equity interest in each of Landstar Metro and Landstar Servicios. As it relates to the noncontrolling interests of Landstar Metro and Landstar Servicios, the Company has the option to purchase, and the minority equityholders have the option to sell, during the period commencing on the third anniversary of September 20, 2017, the closing date of the subscription by the minority equityholders (the “Closing Date”), and at any time after the fourth anniversary of the Closing Date, at fair value all but not less than all of the noncontrolling interests in Landstar Metro and Landstar Servicios. The noncontrolling interests are also subject to customary restrictions on transfer, including a right of first refusal in favor of the Company.

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.

(10) 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

14

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 effect of the increase (decrease) in the cost of insurance claims resulting from unfavorable (favorable) development of prior year self-insured claims estimates on operating income, net income attributable to Landstar System, Inc. and subsidiary and earnings per share attributable to Landstar System, Inc. and subsidiary amounts in the consolidated statements of income for the thirteen-week periods ended March 31, 2018 and April 1, 2017 (in thousands, except per share amounts):

(11) Recent Accounting Pronouncements

Adoption of New Accounting Standards

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09 - Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 is a comprehensive revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. The standard requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 became effective for us December 31, 2017 and permits either a full retrospective or a modified retrospective transition approach. The Company adopted ASU 2014-09 for our transportation services contracts using the modified retrospective method. The adoption of this standard has changed the timing of revenue recognition for most of our transportation business from at delivery to over the transit period as the performance obligation is completed. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company had no material contract assets, contract liabilities or deferred contract costs recorded on the consolidated balance sheets at December 30, 2017 or March 31, 2018. During the thirteen weeks ended March 31, 2018, revenue generated by BCO Independent Contractors, Truck Brokerage Carriers and railroads represented approximately 45%, 48% and 3%, respectively, of the Company’s consolidated revenue. Collectively, revenue generated by air and ocean cargo carriers represented approximately 2% of the Company’s consolidated revenue in the thirteen-week period ended March 31, 2018. Included in truck transportation revenue generated by BCO Independent Contractors and Truck Brokerage Carriers during the thirteen-week period ended March 31, 2018 was $656,135,000 hauled via van equipment, $299,369,000 hauled via unsided/platform equipment and $23,584,000 of less-than-truckload. As of March 31, 2018, the Company had no material remaining performance obligations. The Company does not expect the adoption of the new standard to have a material impact on its net income in future periods.

The cumulative effect of the changes made to our consolidated December 31, 2017 balance sheet for the adoption of ASU 2014-09 was as follows (in thousands):

	Balance at December 30, 2017		Adjustments Due to ASU 2014-09			Balance at December 31, 2017

Accounting Standards Issued But Not Yet Adopted

In February 2016, the FASB issued Accounting Standards Update 2016-02 – Leases (“ASU 2016-02”). ASU 2016-02 requires a company to recognize a right-of-use asset and lease liability for the obligation to make lease payments measured at the present value of the lease payments for all leases with terms greater than twelve months. Companies are required to use a modified retrospective transition approach to recognize leases at the beginning of the earliest period presented. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods therein, and early adoption is permitted. ASU 2016-02 is not expected to have a material impact on the Company’s financial statements.

In June 2016, the FASB issued Accounting Standards Update 2016-13– Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires measurement and recognition of expected versus incurred credit losses for financial assets held. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods therein. The Company is currently evaluating the impact of ASU 2016-13 on its financial statements.

Introduction

Landstar System, Inc. and its subsidiary, Landstar System Holdings, Inc. (together, referred to herein as “Landstar” or the “Company”), is a worldwide asset-light provider of integrated transportation management solutions. The Company offers services to its customers across multiple transportation modes, with the ability to arrange for individual shipments of freight to enterprise-wide solutions to manage all of a customer’s transportation needs. Landstar provides services principally throughout the United States and to a lesser extent in Canada and Mexico, and between the United States and Canada, Mexico and other countries around the world. The Company’s services emphasize safety, information coordination and customer service and are delivered through a network of independent commission sales agents and third party capacity providers linked together by a series of technological applications which are provided and coordinated by the Company. The nature of the Company’s business is such that a significant portion of its operating costs varies directly with revenue.

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

17

“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 $3.6 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. During the thirteen weeks ended March 31, 2018, revenue generated by BCO Independent Contractors, Truck Brokerage Carriers and railroads represented approximately 45%, 48% and 3%, respectively, of the Company’s consolidated revenue. Collectively, revenue generated by air and ocean cargo carriers represented approximately 2% of the Company’s consolidated revenue in the thirteen-week period ended March 31, 2018.

During 2017, the Company incorporated Landstar Metro, S.A.P.I. de C.V., a transportation logistics company (“Landstar Metro”), and Landstar Metro Servicios S.A.P.I. de C.V., a services company (“Landstar Servicios”), each based in Mexico City, Mexico. On September 20, 2017, Landstar Metro acquired substantially all of the assets of the asset-light transportation logistics business of a Mexican transportation logistics company. In connection with the acquisition, individuals affiliated with the seller subscribed in the aggregate for a 30% equity interest in each of Landstar Metro and Landstar Servicios. Landstar Metro provides freight and logistics services within the country of Mexico and in conjunction with Landstar’s U.S./Mexico cross-border services. Landstar Servicios provides various administrative, financial, operational, safety and compliance services to Landstar Metro. The results of operations from Landstar Metro and Landstar Servicios are presented as part of the Company’s transportation logistics segment. Revenue from Landstar Metro represented less than 1% of the Company’s transportation logistics segment revenue in the thirteen-week period ended March 31, 2018.

The insurance segment is comprised of Signature Insurance Company, a wholly owned offshore insurance subsidiary (“Signature”), 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. Revenue at the insurance segment represented approximately 1% of the Company’s consolidated revenue for the thirteen-week period ended March 31, 2018.

Changes in Financial Condition and Results of Operations

Management believes the Company’s success principally depends on its ability to generate freight through its network of independent commission sales agents and to safely and efficiently deliver that freight utilizing third party capacity providers. Management believes the most significant factors to the Company’s success include increasing revenue, sourcing capacity and controlling costs, including insurance and claims.

While customer demand, which is subject to overall economic conditions, ultimately drives increases or decreases in revenue, the Company primarily relies on its independent commission sales agents to establish customer relationships and generate revenue opportunities. Management’s emphasis with respect to revenue growth is on revenue generated by independent commission sales agents who on an annual basis generate $1 million or more of Landstar revenue (“Million Dollar Agents”). Management believes future revenue growth is primarily dependent on its ability to increase both the revenue generated by Million Dollar Agents and the number of Million Dollar Agents through a combination of recruiting new agents, increasing the revenue opportunities generated by existing independent commission sales agents and providing its independent commission sales agents with technology-based tools they may use to grow revenue and increase efficiencies at their businesses. During the 2017 fiscal year, 542 independent commission sales agents generated $1 million or more of Landstar revenue and thus qualified as Million Dollar Agents. During the 2017 fiscal year, the average revenue generated by a Million Dollar Agent was $6,191,000 and revenue generated by Million Dollar Agents in the aggregate represented 92% of consolidated revenue.

18

Management monitors business activity by tracking the number of loads (volume) and revenue per load by mode of transportation. Revenue per load can be influenced by many factors other than a change in price. Those factors include the average length of haul, freight type, special handling and equipment requirements, fuel costs and delivery time requirements. For shipments involving two or more modes of transportation, revenue is generally classified by the mode of transportation having the highest cost for the load. The following table summarizes this information by trailer type for truck transportation and by mode for all others:

Also critical to the Company’s success is its ability to secure capacity, particularly truck capacity, at rates that allow the Company to profitably transport customers’ freight. The following table summarizes the number of available truck capacity providers on the dates indicated:

	March 31, 2018		April 1, 2017
BCO Independent Contractors		9,243		8,772
Truck Brokerage Carriers:
Approved and active (1)		34,659		31,566
Other approved		15,687		15,889
		50,346		47,455
Total available truck capacity providers		59,589		56,227
Trucks provided by BCO Independent Contractors		9,868		9,370

⁽¹⁾ Active refers to Truck Brokerage Carriers who moved at least one load in the 180 days immediately preceding the fiscal quarter end.

The Company incurs costs that are directly related to the transportation of freight that include purchased transportation and commissions to agents. The Company incurs indirect costs associated with the transportation of freight that include other operating costs and insurance and claims. In addition, the Company incurs selling, general and administrative costs essential to administering its business operations. Management continually monitors all components of the costs incurred by the Company and establishes annual cost budgets which, in general, are used to benchmark costs incurred on a monthly basis.

Purchased transportation represents the amount a BCO Independent Contractor or other third party capacity provider is paid to haul freight. The amount of purchased transportation paid to a BCO Independent Contractor is primarily based on a contractually agreed-upon percentage of revenue generated by loads hauled by the BCO Independent Contractor. Purchased transportation paid to a Truck Brokerage Carrier is based on either a negotiated rate for each load hauled or, to a lesser extent, a contractually agreed-upon fixed rate per load. Purchased transportation paid to railroads is based on either a negotiated rate for each load hauled or a contractually agreed-upon fixed rate per load. Purchased transportation paid to air cargo carriers is generally based on a negotiated rate for each load hauled and purchased transportation paid to ocean cargo carriers is generally based on contractually agreed-upon fixed rates. Purchased transportation as a percentage of revenue for truck brokerage, rail intermodal and ocean cargo services is normally higher than that of BCO Independent Contractor and air cargo services. Purchased transportation is the largest component of costs and expenses and, on a consolidated basis, increases or decreases as a percentage of consolidated revenue in proportion to changes in the percentage of consolidated revenue generated through BCO Independent Contractors and other third party capacity providers and external revenue from the insurance segment, consisting of reinsurance premiums. Purchased transportation as a percent of revenue also increases or decreases in relation to the availability of truck brokerage capacity and with changes in the price of fuel on revenue generated by Truck Brokerage Carriers. The Company passes 100% of fuel surcharges billed to customers for freight hauled by BCO Independent Contractors to its BCO Independent Contractors. These fuel surcharges are excluded from revenue and the cost of purchased transportation. Purchased transportation costs are recognized over the transit period as the performance obligation is completed.

Commissions to agents are based on contractually agreed-upon percentages of revenue or net revenue, defined as revenue less the cost of purchased transportation, or net revenue less a contractually agreed upon percentage of revenue retained by Landstar. Commissions to agents as a percentage of consolidated revenue will vary directly with fluctuations in the percentage of consolidated revenue generated by the various modes of transportation and reinsurance premiums and with changes in net revenue margin, defined as net revenue divided by revenue, on services provided by Truck Brokerage Carriers, railroads, air cargo carriers and ocean cargo carriers. Commissions to agents are recognized over the transit period as the performance obligation is completed.

The Company defines gross profit as revenue less the cost of purchased transportation and commissions to agents. Gross profit divided by revenue is referred to as gross profit margin. The Company’s operating margin is defined as operating income divided by gross profit.

In general, gross profit margin on revenue generated by BCO Independent Contractors represents a fixed percentage of revenue due to the nature of the contracts that pay a fixed percentage of revenue to both the BCO Independent Contractors and independent commission sales agents. For revenue generated by Truck Brokerage Carriers, gross profit margin is either fixed or variable as a percent of revenue, depending on the contract with each individual independent commission sales agent. Under certain contracts with independent commission sales agents, the Company retains a fixed percentage of revenue and the agent retains the amount remaining less the cost of purchased transportation (the “retention contracts”). Gross profit margin on revenue generated by railroads, air cargo carriers, ocean cargo carriers and Truck Brokerage Carriers, other than those under retention contracts, is variable in nature as the Company’s contracts with independent

20

commission sales agents provide commissions to agents at a contractually agreed upon percentage of net revenue for these type of loads. Approximately 52% of the Company’s consolidated revenue in the thirteen-week period ended March 31, 2018 was generated under contracts that have a fixed gross profit margin while 48% was under contracts that have a variable gross profit margin.

Maintenance costs for Company-provided trailing equipment and BCO Independent Contractor recruiting and qualification costs are the largest components of other operating costs. Also included in other operating costs are trailer rental costs, the provision for uncollectible advances and other receivables due from BCO Independent Contractors and independent commission sales agents and gains/losses, if any, on sales of Company-owned trailing equipment.

With respect to insurance and claims cost, potential liability associated with accidents in the trucking industry is severe and occurrences are unpredictable. For commercial trucking claims, Landstar retains liability up to $5,000,000 per occurrence. In addition, for commercial trucking claims exceeding its $5,000,000 per occurrence self-insured retention, the Company retains liability up to an additional $700,000 in the aggregate on any claims incurred on or after May 1, 2016 through April 30, 2017, and up to an additional $500,000 in the aggregate on any claims incurred on or after May 1, 2017 through April 30, 2018. 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. The Company’s exposure to liability associated with accidents incurred by Truck Brokerage Carriers, railroads and air and ocean cargo carriers who transport freight on behalf of the Company is reduced by various factors including the extent to which such carriers maintain their own insurance coverage. A material increase in the frequency or severity of accidents, cargo claims or workers’ compensation claims or the material unfavorable development of existing claims could have a material adverse effect on Landstar’s cost of insurance and claims and its results of operations.

During the thirteen-week period ended March 31, 2018, employee compensation and benefits accounted for approximately seventy percent of the Company’s selling, general and administrative costs.

Depreciation and amortization primarily relate to depreciation of trailing equipment and information technology hardware and software.

The following table sets forth the percentage relationship of purchased transportation and commissions to agents, both being direct costs, to revenue and indirect costs as a percentage of gross profit for the periods indicated:

	Thirteen Weeks Ended
	March 31, 2018			April 1, 2017
Revenue		100.0	%		100.0	%
Purchased transportation		77.3			76.3
Commissions to agents		7.8			8.2
Gross profit margin		14.8	%		15.6	%
Gross profit		100.0	%		100.0	%
Investment income		0.6			0.3
Indirect costs and expenses:
Other operating costs, net of gains on asset sales/dispositions		4.9			5.7
Insurance and claims		11.2			11.9
Selling, general and administrative		29.1			31.5
Depreciation and amortization		7.1			8.2
Total costs and expenses		52.2			57.3
Operating margin		48.3	%		43.0	%

Management believes that a discussion of indirect costs as a percentage of gross profit is useful and meaningful to potential investors for the following principal reasons: (1) disclosure of these relative measures (i.e., each indirect operating cost line item as a percentage of gross profit) allows investors to better understand the underlying trends in the Company’s results of operations; (2) due to the generally fixed nature of these indirect costs (other than insurance and claims costs), these relative measures are meaningful to investors’ evaluations of the Company’s management of its indirect costs attributable to operations; (3) management considers this financial information in its

21

decision-making, such as budgeting for infrastructure, trailing equipment and selling, general and administrative costs; and (4) this information facilitates comparisons by investors of the Company’s results to the results of other non-asset or asset-light companies in the transportation and logistics services industry who report “net revenue” in Management Discussion and Analysis, which represents revenue less the cost of purchased transportation. The difference between the Company’s use of the term “gross profit” and use of the term “net revenue” by other companies in the transportation and logistics services industry is due to the direct cost of commissions to agents under the Landstar business model, whereas other companies in this industry generally have no commissions to agents.

Also, as previously mentioned, the Company reports two operating segments: the transportation logistics segment and the insurance segment. External revenue at the insurance segment, representing reinsurance premiums, has historically been relatively consistent at 2% or less of consolidated revenue and generally corresponds directly with the number of trucks provided by BCO Independent Contractors. The discussion of indirect cost line items in Management’s Discussion and Analysis of Financial Condition and Results of Operations considers the Company’s costs on a consolidated basis rather than on a segment basis. Management believes this presentation format is the most appropriate to assist users of the financial statements in understanding the Company’s business for the following reasons: (1) the insurance segment has no other operating costs; (2) discussion of insurance and claims at either segment without reference to the other may create confusion amongst investors and potential investors due to intercompany arrangements and specific deductible programs that affect comparability of financial results by segment between various fiscal periods but that have no effect on the Company from a consolidated reporting perspective; (3) selling, general and administrative costs of the insurance segment comprise less than 10% of consolidated selling, general and administrative costs and have historically been relatively consistent on a year-over-year basis; and (4) the insurance segment has no depreciation and amortization.

THIRTEEN WEEKS ENDED MARCH 31, 2018 COMPARED TO THIRTEEN WEEKS ENDED APRIL 1, 2017

Revenue for the 2018 thirteen-week period was $1,047,926,000, an increase of $267,018,000, or 34%, compared to the 2017 thirteen-week period. Transportation revenue increased $266,292,000, or 35%. The increase in transportation revenue was attributable to an increased number of loads hauled of approximately 12% and an increased revenue per load of approximately 20%. Reinsurance premiums were $12,286,000 and $11,560,000 for the 2018 and 2017 thirteen-week periods, respectively. The increase in revenue from reinsurance premiums was primarily attributable to the increase in the average number of BCO Independent Contractors in the 2018 thirteen-week period compared to the 2017 thirteen-week period.

Truck transportation revenue generated by BCO Independent Contractors and Truck Brokerage Carriers (together, the “third party truck capacity providers”) for the 2018 thirteen-week period was $979,088,000, representing 93% of total revenue, an increase of $252,271,000, or 35%, compared to the 2017 thirteen-week period. The number of loads hauled by third party truck capacity providers increased approximately 12% in the 2018 thirteen-week period compared to the 2017 thirteen-week period, and revenue per load on loads hauled by third party truck capacity providers increased approximately 21% compared to the 2017 thirteen-week period. The increase in the number of loads hauled via truck compared to the 2017 thirteen-week period was due to a broad-based increase in demand across many customers and industries for Landstar’s various truck service offerings. The increase in revenue per load on loads hauled via truck was due to a tighter freight environment experienced during the 2018 thirteen-week period, which resulted in less readily available truck capacity as compared to the 2017 thirteen-week period, and the impact of higher diesel fuel costs on loads hauled via Truck Brokerage Carriers. Revenue per load on loads hauled via van equipment increased 24%, revenue per load on loads hauled via unsided/platform equipment increased 17% and revenue per load on less-than-truckload loadings increased 6% as compared to the 2017 thirteen-week period. Fuel surcharges billed to customers on revenue generated by BCO Independent Contractors are excluded from revenue. Fuel surcharges on Truck Brokerage Carrier revenue identified separately in billings to customers and included as a component of Truck Brokerage Carrier revenue were $22,245,000 and $15,062,000 in the 2018 and 2017 thirteen-week periods, respectively. It should be noted that many customers of truck brokerage services require a single all-in rate that does not separately identify fuel surcharges. Accordingly, the overall impact of changes in fuel prices on revenue and revenue per load on loads hauled via truck is likely to be greater than that indicated.

Transportation revenue generated by rail intermodal, air cargo and ocean cargo carriers (collectively, the “multimode capacity providers”) for the 2018 thirteen-week period was $52,769,000, or 5% of total revenue, an increase of $10,337,000, or 24%, compared to the 2017 thirteen-week period. The number of loads hauled by multimode capacity providers increased approximately 20% in the 2018 thirteen-week period compared to the 2017 thirteen-week period, and revenue per load on revenue generated by multimode capacity providers increased approximately 4% over the same period. The increase in the number of loads hauled by multimode capacity providers was primarily due to a 25% increase in rail intermodal loads and a 20% increase in ocean loads. The increase in both rail intermodal and ocean loads was broad-based across many customers. While revenue per load on loads hauled by multimode capacity providers increased for all modes, the increase of 4% was primarily driven by an increase in revenue per load generated by air cargo carriers. Also, revenue per load on revenue generated by multimode capacity providers is influenced by many factors, including revenue mix among the various modes of transportation used, length of haul, complexity of freight, density of freight lanes, fuel costs and availability of capacity.

22

Purchased transportation was 77.3% and 76.3% of revenue in the 2018 and 2017 thirteen-week periods, respectively. The increase in purchased transportation as a percentage of revenue was primarily due to an increased rate of purchased transportation paid to Truck Brokerage Carriers and a decrease in the percentage of revenue contributed by BCO Independent Contractors, which typically has a lower rate of purchased transportation than revenue generated by Truck Brokerage Carriers. Commissions to agents were 7.8% and 8.2% of revenue in the 2018 and 2017 thirteen-week periods, respectively. The decrease in commissions to agents as a percentage of revenue was primarily attributable to a decreased net revenue margin on revenue generated by Truck Brokerage Carriers.

Investment income was $861,000 and $414,000 in the 2018 and 2017 thirteen-week periods, respectively. The increase in investment income was primarily due to higher average rates of return on investments in the 2018 thirteen-week period and a higher average investment balance held by the insurance segment in the 2018 thirteen-week period.

Other operating costs increased $707,000 in the 2018 thirteen-week period compared to the 2017 thirteen-week period and represented 4.9% of gross profit in the 2018 period compared to 5.7% of gross profit in the 2017 period. The increase in other operating costs compared to the prior year was primarily due to an increased provision for contractor bad debt and increased trailing equipment maintenance costs, partially offset by increased gains on sales of used trailing equipment. The decrease in other operating costs as a percentage of gross profit was caused by the effect of increased gross profit, partially offset by the increase in other operating costs.

Insurance and claims increased $2,847,000 in the 2018 thirteen-week period compared to the 2017 thirteen-week period and represented 11.2% of gross profit in the 2018 period compared to 11.9% of gross profit in the 2017 period. The increase in insurance and claims expense compared to prior year was primarily due to increased net unfavorable development of prior years’ claims in the 2018 period. Net unfavorable development of prior years’ claims was $2,558,000 in the 2018 thirteen-week period, while net favorable development of prior years’ claims was $104,000 in the 2017 thirteen-week period. The decrease in insurance and claims as a percent of gross profit was caused by the effect of increased gross profit, partially offset by the increase in insurance and claims costs.

Selling, general and administrative costs increased $6,928,000 in the 2018 thirteen-week period compared to the 2017 thirteen-week period and represented 29.1% of gross profit in the 2018 period compared to 31.5% of gross profit in the 2017 period. The increase in selling, general and administrative costs compared to prior year was attributable to increased stock-based compensation expense, an increased provision for incentive compensation and increased wages. Included in selling, general and administrative costs is stock-based compensation expense of $3,710,000 and $994,000 for the 2018 and 2017 thirteen-week periods, respectively, and incentive compensation expense of $4,131,000 and $2,872,000 for the 2018 and 2017 thirteen-week periods, respectively. The decrease in selling, general and administrative costs as a percent of gross profit was due primarily to the effect of increased gross profit, partially offset by the increase in selling, general and administrative costs.

Depreciation and amortization increased $1,063,000 in the 2018 thirteen-week period compared to the 2017 thirteen-week period and represented 7.1% of gross profit in the 2018 period compared to 8.2% of gross profit in the 2017 period. The increase in depreciation and amortization expenses was due to an increased number of owned trailers in response to increased customer demand for the Company’s drop and hook services and increased depreciation on information technology assets placed in service during the second half of fiscal year 2017. The decrease in depreciation and amortization as a percentage of gross profit was primarily due to the effect of increased gross profit, partially offset by the increased depreciation costs.

Interest and debt expense in the 2018 thirteen-week period decreased $283,000 compared to the 2017 thirteen-week period. The decrease in interest and debt expense was primarily attributable to increased interest income earned on cash balances held by the transportation logistics segment.

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. The provisions for income taxes for the 2018 and 2017 thirteen-week periods were based on estimated annual effective income tax rates of 24.5% and 38.2%, respectively, adjusted for discrete events, such as benefits resulting from stock-based awards. The effective income tax rates for the 2018 and 2017 thirteen-week periods were 22.7% and 36.8%, respectively. The increase as compared to the statutory federal income tax rate for the 2018 thirteen-week period was primarily attributable to state taxes, the elimination of the performance-based exception under Section 162(m) included in the Tax Reform Act and the meals and entertainment exclusion. The increase as compared to the statutory federal income tax rate for the 2017 thirteen-week period was primarily attributable to state taxes, the meals and entertainment exclusion and non-deductible stock-based compensation. The effective income tax rate in the 2018 thirteen-week

23

period of 22.7% was lower than the 24.5% estimated annual effective income tax rate primarily due to excess tax benefits recognized on stock-based compensation arrangements in the 2018 period. The effective income tax rate in the 2017 thirteen-week period of 36.8% was less than the 38.2% estimated annual effective income tax rate primarily due to excess tax benefits recognized on stock-based compensation arrangements and disqualifying dispositions of the Company’s common stock by employees who obtained the stock through the exercises of incentive stock options in the 2017 period.

The net loss attributable to noncontrolling interest of $44,000 in the 2018 thirteen-week period represents the noncontrolling investors’ 30% share of the net loss incurred by Landstar Metro and Landstar Servicios.

Net income attributable to the Company was $57,517,000, or $1.37 per common share ($1.37 per diluted share), in the 2018 thirteen-week period. Net income attributable to the Company was $32,383,000, or $0.77 per common share ($0.77 per diluted share), in the 2017 thirteen-week period. Net income attributable to the Company was favorably impacted by the enactment of the Tax Cuts and Jobs Act by approximately $10,186,000, or $0.24 per common share ($0.24 per diluted share), in the 2018 thirteen-week period, as a result of the permanent reduction of the U.S. corporate income tax rate from a maximum of 35% to a flat 21%.

CAPITAL RESOURCES AND LIQUIDITY

Working capital and the ratio of current assets to current liabilities were $455,757,000 and 2.0 to 1, respectively, at March 31, 2018, compared with $412,560,000 and 1.8 to 1, respectively, at December 30, 2017. Landstar has historically operated with current ratios within the range of 1.5 to 1 to 2.0 to 1. Cash provided by operating activities was $72,002,000 in the 2018 thirteen-week period compared with $61,948,000 in the 2017 thirteen-week period. The increase in cash flow provided by operating activities was primarily attributable to increased net income, partially offset by the timing of collections of trade receivables.

The Company declared and paid $0.15 per share, or $6,308,000 in the aggregate, in cash dividends during the thirteen-week period ended March 31, 2018 and, during such period, also paid $62,985,000 of dividends payable which were declared during fiscal year 2017 and included in current liabilities in the consolidated balance sheet at December 30, 2017. The Company declared and paid $0.09 per share, or $3,770,000 in the aggregate, in cash dividends during the thirteen-week period ended April 1, 2017. During the thirteen-week period ended March 31, 2018, the Company purchased 14,354 shares of its common stock at a total cost of $1,508,000. During the thirteen-week period ended April 1, 2017, the Company did not purchase any shares of its common stock. As of March 31, 2018, the Company may purchase up to 2,985,646 shares of its common stock under its authorized stock purchase program. Long-term debt, including current maturities, was $113,281,000 at March 31, 2018, $11,832,000 lower than at December 30, 2017.

Equity was $706,280,000, or 86% of total capitalization (defined as long-term debt including current maturities plus equity), at March 31, 2018, compared to $653,877,000, or 84% of total capitalization, at December 30, 2017. The increase in equity was primarily a result of net income, partially offset by dividends declared by the Company in the 2018 thirteen-week period.

On 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 2, 2016.

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.

24

At March 31, 2018, the Company had no borrowings outstanding and $33,115,000 of letters of credit outstanding under the Credit Agreement. At March 31, 2018, there was $216,885,000 available for future borrowings under the Credit Agreement. In addition, the Company has $61,186,000 in letters of credit outstanding as collateral for insurance claims that are secured by investments totaling $67,984,000 at March 31, 2018. Investments, all of which are carried at fair value, include primarily investment-grade bonds having maturities of up to five years. Fair value of investments is based primarily on quoted market prices. See Notes to Consolidated Financial Statements included herein for further discussion on measurement of fair value of investments.

Historically, the Company has generated sufficient operating cash flow to meet its debt service requirements, fund continued growth, both organic and through acquisitions, complete or execute share purchases of its common stock under authorized share purchase programs, pay dividends and meet working capital needs. As an asset-light provider of integrated transportation management solutions, the Company’s annual capital requirements for operating property are generally for trailing equipment and information technology hardware and software. In addition, a significant portion of the trailing equipment used by the Company is provided by third party capacity providers, thereby reducing the Company’s capital requirements. During the 2018 thirteen-week period, the Company purchased $3,814,000 of operating property. Included in the $3,814,000 of purchases of operating property during the 2018 thirteen-week period was $2,162,000 related to the completion of its Laredo, Texas facility for which the Company accrued a corresponding liability in accounts payable as of December 30, 2017. Landstar anticipates acquiring either by purchase or lease financing during the remainder of fiscal year 2018 approximately $56,000,000 in operating property, consisting primarily of new trailing equipment to replace older trailing equipment and information technology equipment.

On September 20, 2017 the Company completed the Landstar Metro acquisition, as described in footnote 1 to our unaudited consolidated financial statements. In connection with the acquisition, the Company assumed approximately $2,200,000 in liabilities consisting of additional contingent purchase price and associated indirect taxes, of which approximately $700,000 remained outstanding at March 31, 2018. As it relates to the non-controlling interests of Landstar Metro and Landstar Servicios, the Company has the option to purchase, and the minority equityholders have the option to sell, during the period commencing on the third anniversary of September 20, 2017, the closing date of the subscription by the minority equityholders (the “Closing Date”), and at any time after the fourth anniversary of the Closing Date, at fair value all but not less than all of the noncontrolling interests in Landstar Metro and Landstar Servicios. The noncontrolling interests are also subject to customary restrictions on transfer, including a right of first refusal in favor of the Company.

Management believes that cash flow from operations combined with the Company’s borrowing capacity under the Credit Agreement will be adequate to meet Landstar’s debt service requirements, fund continued growth, both internal and through acquisitions, pay dividends, complete the authorized share purchase program and meet working capital needs.

LEGAL MATTERS

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.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

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. Historically, management’s estimates for uncollectible receivables have been materially correct. Although management believes the amount of the allowance for both trade and other receivables at March 31, 2018 is appropriate, a prolonged period of low or no economic growth may adversely affect the collection of these receivables. In addition, liquidity concerns and/or unanticipated bankruptcy proceedings at any of the Company’s larger customers in which the Company is carrying a significant receivable could result in an increase in the provision for uncollectible receivables and have a significant impact on the Company’s results of operations in a given quarter or year. However, it is not expected that an uncollectible accounts receivable resulting from an individual customer would have a significant impact on the Company’s financial condition. Conversely, a more robust economic environment or the recovery of a previously provided for uncollectible receivable from an individual customer may result in the realization of some portion of the estimated uncollectible receivables.

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

25

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. During the 2018 and 2017 thirteen-week periods, insurance and claims costs included $2,558,000 of net unfavorable and $104,000 of net favorable adjustments to prior years’ claims estimates, respectively. It is reasonably likely that the ultimate outcome of settling all outstanding claims will be more or less than the estimated claims reserve at March 31, 2018.

The Company utilizes certain income tax planning strategies to reduce its overall cost of income taxes. If the Company were to be subject to an audit, it is possible that certain strategies might be disallowed resulting in an increased liability for income taxes. Certain of these tax planning strategies result in a level of uncertainty as to whether the related tax positions taken by the Company would result in a recognizable benefit. The Company has provided for its estimated exposure attributable to such tax positions due to the corresponding level of uncertainty with respect to the amount of income tax benefit that may ultimately be realized. Management believes that the provision for liabilities resulting from the uncertainty in certain income tax positions is appropriate. To date, the Company has not experienced an examination by governmental revenue authorities that would lead management to believe that the Company’s past provisions for exposures related to the uncertainty of such income tax positions are not appropriate.

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. 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. 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 revaluation of its ending net deferred tax liabilities at December 30, 2017 and deemed repatriated earnings in its consolidated financial statements for the year ended December 30, 2017. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued and actions the Company may take as a result of the Tax Reform Act. The accounting is expected to be complete when the 2017 U.S. corporate income tax return is filed in 2018.

Significant variances from management’s estimates for the amount of uncollectible receivables, the ultimate resolution of self-insured claims and the provision for uncertainty in income tax positions could each be expected to positively or negatively affect Landstar’s earnings in a given quarter or year. However, management believes that the ultimate resolution of these items, given a range of reasonably likely outcomes, will not significantly affect the long-term financial condition of Landstar or its ability to fund its continuing operations.

EFFECTS OF INFLATION

Management does not believe inflation has had a material impact on the results of operations or financial condition of Landstar in the past five years. However, inflation in excess of historic trends might have an adverse effect on the Company’s results of operations in the future.

SEASONALITY

Landstar’s operations are subject to seasonal trends common to the trucking industry. Truckload shipments for the quarter ending in March are typically lower than for the quarters ending June, September and December.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to changes in interest rates as a result of its financing activities, primarily its borrowings on its revolving credit facility, and investing activities with respect to investments held by the insurance segment.

On 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.

26

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%. As of March 31, 2018 and during the entire 2018 first quarter, the Company had no borrowings outstanding under the Credit Agreement.

Long-term investments, all of which are available-for-sale and are carried at fair value, include primarily investment-grade bonds having maturities of up to five years. Assuming that the long-term portion of investments remains at $71,611,000, the balance at March 31, 2018, a hypothetical increase or decrease in interest rates of 100 basis points would not have a material impact on future earnings on an annualized basis. Short-term investments consist of short-term investment-grade instruments and the current maturities of investment-grade corporate bonds. Accordingly, any future interest rate risk on these short-term investments would not be material to the Company’s operating results.

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. The assets held at the Company’s Canadian and Mexican subsidiaries at March 31, 2018 were, as translated to U.S. dollars, less than 3% of total consolidated assets. Accordingly, any translation gain or loss related to the Canadian and Mexican operations would not be material.

Item 4. Controls and Procedures

As of the end of the period covered by this quarterly report on Form 10-Q, an evaluation was carried out, under the supervision and with the participation of the Company’s management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended). Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures were effective as of March 31, 2018 to provide reasonable assurance that information required to be disclosed by the Company in reports that it filed or submitted under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

There were no significant changes in the Company’s internal control over financial reporting during the Company’s fiscal quarter ended March 31, 2018 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

In designing and evaluating disclosure controls and procedures, Company management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of the inherent limitation in any control system, no evaluation or implementation of a control system can provide complete assurance that all control issues and all possible instances of fraud have been or will be detected.

PART II

OTHER INFORMATION

Item 1. Legal Proceedings

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.

27

Item 1A. Risk Factors

For a discussion identifying additional risk factors and other important factors that could cause actual results to differ materially from those anticipated, see the discussions under Part I, Item 1A, “Risk Factors” in the Company’s Annual Report on Form 10-K for the fiscal year ended December 30, 2017 and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Notes to Consolidated Financial Statements” in this Quarterly Report on Form 10-Q.

On May 19, 2015, the Landstar System, Inc. Board of Directors authorized the Company to increase the number of shares of the Company’s common stock that the Company is authorized to purchase from time to time in the open market and in privately negotiated transactions under a previously announced purchase program to 3,000,000 shares. On December 11, 2017, the Landstar System, Inc. Board of Directors authorized the Company to purchase up to an additional 1,963,875 shares of the Company’s common stock from time to time in the open market and in privately negotiated transactions. As of March 31, 2018, the Company has authorization to purchase 2,985,646 shares of its common stock under these programs. No specific expiration date has been assigned to either the May 19, 2015 or December 11, 2017 authorizations.

Dividends

During the thirteen-week period ended March 31, 2018, Landstar paid dividends as follows:

Dividend Amount per Share	Declaration Date	Record Date	Payment Date
$    1.50	December 11, 2017	January 12, 2018	January 26, 2018
$    0.15	January 30, 2018	February 19, 2018	March 16, 2018

Dividends payable of $1.50 per share, or $62,985,000 in the aggregate, was included in current liabilities in the consolidated balance sheet at December 30, 2017.

On 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 provides for a restriction on cash dividends and other distributions to stockholders on the Company’s capital stock in the event 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, as defined in the Credit Agreement, would exceed 2.5 to 1 on a pro forma basis as of the end of the Company’s most recently completed fiscal quarter.

Business Description

The consolidated financial statements include the accounts of Landstar System, Inc. and its subsidiary, Landstar System Holdings, Inc., and reflect all adjustments (all of a normal, recurring nature) which are, in the opinion of management, necessary for a fair statement of the results for the periods presented. The preparation of the consolidated financial statements requires the use of management’s estimates. Actual results could differ from those estimates. Landstar System, Inc. and its subsidiary are herein referred to as “Landstar” or the “Company.” Significant intercompany accounts have been eliminated in consolidation.

Landstar owns, through various subsidiaries, a controlling interest in Landstar Metro, S.A.P.I. de C.V., a transportation logistics company (“Landstar Metro”), and Landstar Metro Servicios S.A.P.I. de C.V., a services company (“Landstar Servicios”), each based in Mexico City, Mexico. Given Landstar’s controlling interest in each of Landstar Metro and Landstar Servicios, the accounts of Landstar Metro and Landstar Servicios have been consolidated herein and a noncontrolling interest has been recorded for the noncontrolling investors’ interests in the net assets and operations of Landstar Metro and Landstar Servicios.

Acquired Business and Noncontrolling Interests

(1) 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 of the asset-light transportation logistics business of Fletes Avella, S.A. de C.V., a Mexican transportation logistics company. At March 31, 2018 and December 30, 2017, there was approximately $700,000 and $1,900,000, respectively, in liabilities outstanding consisting of additional contingent purchase price and associated indirect taxes. In connection with the acquisition, individuals affiliated with the seller subscribed in the aggregate for a 30% equity interest in each of Landstar Metro and Landstar Servicios. The asset acquisition by Landstar Metro 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 $8,500,000 as of March 31, 2018. With respect to this goodwill, 70% is expected to be deductible by the Company for U.S. income tax purposes, and following a purchase of the noncontrolling interests by the Company, up to 100% of this goodwill would be expected to be deductible by the Company. Pro forma financial information for prior periods is not presented as the Company does not believe the acquisition to be material to our consolidated results. The results of operations from Landstar Metro and Landstar Servicios are presented as part of the Company’s transportations logistics segment.

As it relates to the noncontrolling interests of Landstar Metro and Landstar Servicios, the Company has the option to purchase, and the minority equityholders have the option to sell, during the period commencing on the third anniversary of September 20, 2017, the closing date of the subscription by the minority equityholders (the “Closing Date”), and at any time after the fourth anniversary of the Closing Date, at fair value all but not less than all of the noncontrolling interests in Landstar Metro and Landstar Servicios. The noncontrolling interests are also subject to customary restrictions on transfer, including a right of first refusal in favor of the Company.

As of March 31, 2018, 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):

	Thirteen Weeks Ended

Forfeited		(92,880	)	$	52.36
Outstanding at March 31, 2018		282,172		$	66.72

During the thirteen-week period ended March 31, 2018, the Company granted RSUs with a performance condition. RSUs with a performance condition granted on February 2, 2018 may vest on January 31 of 2021, 2022 and 2023 based on growth in operating income and pre-tax income per share from continuing operations attributable to Landstar System, Inc. and subsidiary as compared to the results from the 2017 fiscal year. Outstanding RSUs at both December 30, 2017 and March 31, 2018 include RSUs with a performance condition and RSUs with a market condition, as further described in the Company’s 2017 Annual Report on Form 10-K.

The Company recognized approximately $3,153,000 and $524,000 of share-based compensation expense related to RSU awards in the thirteen-week periods ended March 31, 2018 and April 1, 2017, respectively. As of March 31, 2018, there was a maximum of $30.2 million of total unrecognized compensation cost related to RSU awards granted under the Plans with an expected average remaining life of approximately 3.5 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 following table summarizes information regarding the Company’s outstanding stock options under the Plans:

						Weighted Average
	Number of			Weighted Average Exercise Price		Remaining Contractual		Aggregate Intrinsic

The total intrinsic value of stock options exercised during the thirteen-week periods ended March 31, 2018 and April 1, 2017 was $2,463,000 and $3,620,000, respectively.

As of March 31, 2018, 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 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 30, 2017		54,755		$	78.02
Granted		16,863		$	114.13
Vested		(9,819	)	$	65.27
Forfeited		(1,757	)	$	71.12
Non-vested at March 31, 2018		60,042		$	90.45

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 the grant or the third, fourth and fifth anniversary of the date of the grant, or 100% on the first 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 will 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 March 31, 2018, there was $4,236,000 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 2.9 years.

Income Taxes

(3) Income Taxes

The Tax Cuts and Jobs Act (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. The provisions for income taxes for the 2018 and 2017 thirteen-week periods were based on estimated annual effective income tax rates of 24.5% and 38.2%, respectively, adjusted for discrete events, such as benefits resulting from stock-based awards. The applicable effective income tax rates for the 2018 and 2017 thirteen-week periods were 22.7% and 36.8%, respectively, which were higher than the applicable statutory federal income tax rates of 21% and 35%, respectively. The increase as compared to the statutory federal income tax rate for the 2018 thirteen-week period was primarily attributable to state taxes, the elimination of the performance-based exception under Section 162(m) included in the Tax Reform Act and the meals and entertainment exclusion, partially offset by excess tax benefits realized on stock based awards. The increase as compared to the statutory federal income tax rate for the 2017 thirteen-week period was primarily attributable to state taxes, the meals and entertainment exclusion and non-deductible stock-based compensation, partially offset by excess tax benefits realized on stock based awards and income tax benefits recognized on disqualifying dispositions on the Company’s common stock.

(4) 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):

	Thirteen Weeks Ended

Incremental shares from assumed exercises of stock options		60		119
Average number of common shares and common share equivalents outstanding		42,098		41,998

For each of the thirteen-week periods ended March 31, 2018 and April 1, 2017, no 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.

Investments

(8) Investments

Investments include primarily investment-grade corporate bonds 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 money market investments and Level 2 inputs related to investment-grade corporate bonds, asset-backed securities and direct obligations of government agencies. Unrealized losses, net of unrealized gains, on the investments in the bond portfolio were $1,113,000 and $223,000 at March 31, 2018 and December 30, 2017, respectively.

The amortized cost and fair values of available-for-sale investments are as follows at March 31, 2018 and December 30, 2017 (in thousands):

Total	$	43,186	$	224	$	14,648	$	116	$	57,834	$	340

The Company believes unrealized losses on investments were primarily caused by rising interest rates rather than changes in credit quality. 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 March 31, 2018.

Short-term investments include $39,014,000 in current maturities of investments held by the Company’s insurance segment at March 31, 2018. The non-current portion of the bond portfolio of $71,611,000 is included in other assets. The short-term investments, together with $28,970,000 of non-current investments, provide collateral for the $61,186,000 of letters of credit issued to guarantee payment of insurance claims. As of March 31, 2018, Landstar also had $33,115,000 of additional letters of credit outstanding under the Company’s Credit Agreement.

During 2017, the Company incorporated each of Landstar Metro and Landstar Servicios. On September 20, 2017, Landstar Metro acquired substantially all of the assets of the asset-light transportation logistics business of Fletes Avella, S.A. de C.V., a Mexican transportation logistics company. In connection with the acquisition, individuals affiliated with the seller subscribed in the aggregate for a 30% equity interest in each of Landstar Metro and Landstar Servicios. As it relates to the noncontrolling interests of Landstar Metro and Landstar Servicios, the Company has the option to purchase, and the minority equityholders have the option to sell, during the period commencing on the third anniversary of September 20, 2017, the closing date of the subscription by the minority equityholders (the “Closing Date”), and at any time after the fourth anniversary of the Closing Date, at fair value all but not less than all of the noncontrolling interests in Landstar Metro and Landstar Servicios. The noncontrolling interests are also subject to customary restrictions on transfer, including a right of first refusal in favor of the Company.

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.

(10) 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.

Adoption of New Accounting Standards

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-09 - Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 is a comprehensive revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. The standard requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 became effective for us December 31, 2017 and permits either a full retrospective or a modified retrospective transition approach. The Company adopted ASU 2014-09 for our transportation services contracts using the modified retrospective method. The adoption of this standard has changed the timing of revenue recognition for most of our transportation business from at delivery to over the transit period as the performance obligation is completed. The Company recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company had no material contract assets, contract liabilities or deferred contract costs recorded on the consolidated balance sheets at December 30, 2017 or March 31, 2018. During the thirteen weeks ended March 31, 2018, revenue generated by BCO Independent Contractors, Truck Brokerage Carriers and railroads represented approximately 45%, 48% and 3%, respectively, of the Company’s consolidated revenue. Collectively, revenue generated by air and ocean cargo carriers represented approximately 2% of the Company’s consolidated revenue in the thirteen-week period ended March 31, 2018. Included in truck transportation revenue generated by BCO Independent Contractors and Truck Brokerage Carriers during the thirteen-week period ended March 31, 2018 was $656,135,000 hauled via van equipment, $299,369,000 hauled via unsided/platform equipment and $23,584,000 of less-than-truckload. As of March 31, 2018, the Company had no material remaining performance obligations. The Company does not expect the adoption of the new standard to have a material impact on its net income in future periods.

The cumulative effect of the changes made to our consolidated December 31, 2017 balance sheet for the adoption of ASU 2014-09 was as follows (in thousands):

Accounting Standards Issued But Not Yet Adopted

In February 2016, the FASB issued Accounting Standards Update 2016-02 – Leases (“ASU 2016-02”). ASU 2016-02 requires a company to recognize a right-of-use asset and lease liability for the obligation to make lease payments measured at the present value of the lease payments for all leases with terms greater than twelve months. Companies are required to use a modified retrospective transition approach to recognize leases at the beginning of the earliest period presented. ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, and interim periods therein, and early adoption is permitted. ASU 2016-02 is not expected to have a material impact on the Company’s financial statements.

In June 2016, the FASB issued Accounting Standards Update 2016-13– Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires measurement and recognition of expected versus incurred credit losses for financial assets held. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods therein. The Company is currently evaluating the impact of ASU 2016-13 on its financial statements.
