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 or fifth anniversary of the date of the grant. For restricted stock awards granted under the 2013 DSCP plan, each recipient may elect to defer receipt of shares and instead receive restricted stock units (“Deferred Stock Units”), which represent contingent rights to receive shares of the Company’s common stock on the date of recipient separation from service from the Board of Directors, or, if earlier, upon a change in control event of the Company. Deferred Stock Units become vested 100% on the first anniversary of the date of the grant. Deferred Stock Units do not represent actual ownership in shares of the Company’s common stock and the recipient does not have voting rights or other incidents of ownership until the shares are issued. However, Deferred Stock Units do contain the right to receive dividend equivalent payments prior to settlement into shares. As of June 29, 2019, there was $4,996,000 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 2.3 years. |

| Investments |
Investments include primarily investment-grade corporate bonds and U.S. Treasury obligations having maturities of up to five years (the “bond portfolio”) and money market investments. Investments in the bond portfolio are reported as available-for-sale and are carried at fair value. Investments maturing less than one year from the balance sheet date are included in short-term investments and investments maturing more than one year from the balance sheet date are included in other assets in the consolidated balance sheets. Management performs an analysis of the nature of the unrealized losses on available-for-sale investments to determine whether such losses are other-than-temporary. Unrealized losses, representing the excess of the purchase price of an investment over its fair value as of the end of a period, considered to be other-than-temporary, are to be included as a charge in the statement of income, while unrealized lossesconsidered to be temporary are to be included as a component of equity. Investments whose values are based on quoted market prices in active markets are classified within Level 1. Investments that trade in markets that are not considered to be active, but are valued based on quoted market prices, are classified within Level 2. As Level 2 investments include positions that are not traded in active markets, valuations may be adjusted to reflect illiquidity and/or non-transferability, which are generally based on available market information. Any transfers between levels are recognized as of the beginning of any reporting period. Fair value of the bond portfolio was determined using Level 1 inputs related to U.S. Treasury obligations and money market investments and Level 2 inputs related to investment-grade corporate bonds, asset-backed securities and direct obligations of government agencies. Unrealized gains, net of unrealized losses, on the investments in the bond portfolio were $1,115,000 at June 29, 2019, while unrealized losses, net of unrealized gains, on the investments in the bond portfolio were $1,184,000 at December 29, 2018, respectively. The amortized cost and fair values of
available-for-sale investments are as follows at June 29, 2019 and December 29, 2018 (in thousands):
For those
available-for-sale investments with unrealized losses at June 29, 2019 and December 29, 2018, the following table summarizes the duration of the unrealized loss (in thousands):
The Company expects to recover the amortized cost basis of these securities as it does not intend to sell, and does not anticipate being required to sell, these securities before recovery of the cost basis. For these reasons, the Company does not consider the unrealized losses on these securities to be other-than-temporary at June 29, 2019. |

| Leases |
Landstar’s noncancelable leases are primarily comprised of finance leases for the acquisition of new trailing equipment. Each finance lease for the acquisition of trailing equipment is a five year lease with a $1 purchase option for the applicable equipment at lease expiration. Substantially all of Landstar’s operating lease right-of-use assets and operating lease liabilities represent leases for orientation centers for BCO Independent Contractors and office space used to conduct Landstar’s business. These leases do not have significant rent escalation holidays, concessions, leasehold improvement incentives or other build-out clauses. Further, the leases do not contain contingent rent provisions. Landstar also leases certain trailing equipment to supplement the Company-owned trailer fleet under “month-to-month” lease terms, which are not required to be recorded on the balance sheet due to the less than twelve month lease term exemption. Sublease income is primarily comprised of weekly trailing equipment rentals to our BCO Independent Contractors. Most of Landstar’s operating leases include one or more options to renew. The exercise of lease renewal options is typically at Landstar’s sole discretion, and, as such, the majority of renewals to extend the lease terms are not included in the right-of-use assets and lease liabilities as they are not reasonably certain of exercise. Landstar regularly evaluates the renewal options, and when they are reasonably certain of exercise, Landstar includes the renewal period in the lease term.As most of Landstar’s operating leases do not provide an implicit rate, Landstar utilized its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. Landstar has a centrally managed treasury function; therefore, based on the applicable lease terms and the current economic environment, we apply a portfolio approach for determining the incremental borrowing rate. The components of lease cost for finance leases and operating leases for the twenty six weeks ended June 29, 2019 were (in thousands):

| Commitments and Contingencies |
Short-term investments include $35,138,000 in current maturities of investments held by the Company’s insurance segment at June 29, 2019. The non-current p ortion of the bond portfolio of $ 80,682,000 is included in other assets. The short-term investments, together with $ 33,199,000 of non-current investments, provide collateral for the $ 61,503,000 of letters of credit issued to guarantee payment of insurance claims. As of June 29, 2019, Landstar also had $ 34,367,000 of additional letters of credit outstanding under the Company’s Credit Agreement. On January 25, 2019, a purported class action was filed in the Superior Court of the State of California for the County of San Bernardino against Landstar System, Inc. and Landstar Ranger, Inc. (together, the “Defendants”). The complaint purports to bring this action on behalf of Hany Tanious, as an individual, and “all owner operators who performed work for the Defendants, and who were classified as independent contractors, during the four years preceding the filing of this action through the present.” On June 11, 2019, the Defendants filed a Notice of Removal that resulted in the removal of the case from state court to federal court, where it was assigned to Judge Dale S. Fischer of the United State District Court for the Central District of California. Mr. Tanious is a truck owner-operator and formerly an independent contractor who was a party to an independent contractor operating agreement with Landstar Ranger, Inc. The complaint asserts claims based on the alleged misclassification of Mr. Tanious as an independent contractor and alleges violations under California law relating to overtime, minimum wage, meal and rest breaks, failure to reimburse certain expenses, wage statements, waiting time and unfair competition. Mr. Tanious is seeking, on behalf of himself and the purported class, payment of minimum wages, restitution and certain statutory damages and penalties, including compensatory, consequential, general, liquidated and special damages. None of the California Labor Code provisions under which Mr. Tanious seeks relief apply to independent contractors. Due to a number of factors including the preliminary status of this matter, the Company does not believe it is in a position to conclude whether or not there is a reasonable possibility of an adverse outcome in this case or what damages, if any, the plaintiffs would be awarded should they prevail on all or any part of their claims. However, the Company believes it has meritorious defenses and it intends to assert these defenses vigorously. The Company is involved in certain claims and pending litigation arising from the normal conduct of business. Many of these claims are covered in whole or in part by insurance. Based on knowledge of the facts and, in certain cases, opinions of outside counsel, management believes that adequate provisions have been made for probable losses with respect to the resolution of all such claims and pending litigation and that the ultimate outcome, after provisions therefor, will not have a material adverse effect on the financial condition of the Company, but could have a material effect on the results of operations in a given quarter or year. |

| Change in Accounting Estimate for Self-Insured Claims |
Landstar provides for the estimated costs of self-insured claims primarily on an actuarial basis. The amount recorded for the estimated liability for claims incurred is based upon the facts and circumstances known on the applicable balance sheet date. The ultimate resolution of these claims may be for an amount greater or less than the amount estimated by management. The Company continually revises its existing claim estimates as new or revised information becomes available on the status of each claim. Historically, the Company has experienced both favorable and unfavorable development of prior years’ claims estimates. The following table summarizes the effect of the increase in the cost of insurance claims resulting from unfavorable development of prior year self-insured claims estimates on operating income, net income attributable to Landstar System, Inc. and subsidiary and earnings per share attributable to Landstar System, Inc. and subsidiary set forth in the consolidated statements of income for the
twenty-six-week and thirteen-week periods ended June 29, 2019 and June 30, 2018 (in thousands, except per share amounts):
The unfavorable development of prior years’ claims in the thirteen-week period ended June 30, 2018 was primarily attributable to three claims. |
