Pay vs Performance Disclosure [Table] |  |  |
Pay vs Performance [Table Text Block] | PAY VERSUS PERFORMANCE As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, Landstar is providing the following additional information regarding the relationship between executive compensation and the financial performance of the Company. For further information concerning the Company’s variable pay-for-performance philosophy and how the Company aligns executive compensation with the Company’s performance, please refer to “ Compensation Discussion and Analysis ” in this Proxy Statement. The following table summarizes the “compensation actually paid” to (i) the Principal Executive Officer (“PEO”) and (ii) the average “compensation actually paid” to the remaining Named Executive Officers other than the PEO with respect to applicable fiscal years. “Compensation actually paid” does not correlate to the total amount of cash or equity compensation that the executive actually realized or was paid during the fiscal year. Instead, it is a nuanced calculation that includes the increase (or decrease) in value of certain elements of compensation ( i.e. , equity compensation) over the fiscal year, even if granted in a prior year. The amounts that the executive will ultimately receive with respect to these types of compensation ( i.e. , when and if the equity awards vest) are likely to be different from the amounts disclosed in this column of the Pay Versus Performance table set forth below. The following Pay Versus Performance table also provides certain information describing the Company’s financial performance for each of the covered fiscal years. Pay Versus Performance Table

(1) | The dollar amounts reported in column (b) are the amounts of total compensation reported for Mr. Gattoni, the Company’s President and Chief Executive Officer and PEO, for each corresponding year in the “Total” column of the Summary Compensation Table included in the section “Compensation of Named Executives ” in this Proxy Statement.
(2) | The dollar amounts reported in column (c) represent the amount of “compensation actually paid” to Mr. Gattoni, as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to Mr. Gattoni during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to Mr. Gattoni’s total compensation for each year to determine the compensation actually paid:
Year |  | Reported Summary Compensation Table Total for PEO |  |  | Reported Value of Equity Awards (a) |  |  | Equity Award Adjustments (b) |  |  | Compensation Actually Paid to PEO |
2022 |  |  | 4,574,748 |  |  |  | 1,429,976 |  |  |  | (209,352 | ) |  |  | 2,935,420 |
2021 |  |  | 5,398,583 |  |  |  | 1,429,787 |  |  |  | 13,866,140 |  |  |  | 17,834,936 |

(a) | The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” column in the Summary Compensation Table for the applicable year.
(b) | The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: (i) the year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year; (ii) the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year; (iii) for awards granted in prior years that vest in the applicable year, the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value; (iv) for awards granted in prior years that are determined to fail to meet the applicable vesting conditions during the applicable year, a deduction for the amount equal to the fair value at the end of the prior fiscal year; and (v) the dollar value of any dividends or other earnings paid on equity awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year. The fair value of equity awards at each measurement date is computed in a manner consistent with the fair value methodology used to account for equity awards in the Company’s audited consolidated financial statements in accordance with generally accepted accounting principles and included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022. For restricted stock awards, the fair value as of the end of the covered fiscal year is computed as the unvested restricted shares outstanding as of the end of the covered fiscal year multiplied by the Company’s closing stock price as of the last business day of the covered fiscal year. For RSUs with a performance or market condition, the fair value as of the end of the covered fiscal year is computed based on the unvested RSUs expected to vest based on the most probable outcome of the performance or market condition for these awards multiplied by the Company’s closing stock price as of the last business day of the covered fiscal year. For stock awards vested during the covered fiscal year, the fair value at vesting is calculated as the number of shares vested multiplied by the average of the high and low stock prices on the vesting date. The amounts deducted or added in calculating the equity award adjustments are as follows:
Year |  | Year End Fair Value of Equity Awards Granted in the Year |  |  | Year over Year Change in Fair Value of Outstanding and Unvested Equity Awards |  |  | Year over Year Change in Fair Value of Equity Awards Granted in Prior Years that Vested in the Year |  |  | Fair Value at the End of the Prior Year of Equity Awards that Failed to Meet Vesting Conditions in the Year |  |  | Value of Dividends or other Earnings Paid on Stock or Option Awards not Otherwise Reflected in Fair Value or Total Compensation |  |  | Total Equity Award Adjustments |
