Savings And Deferred Compensation Plans [Abstract] |
Savings and Deferred Compensation Plans | Savings and Deferred Compensation Plans Savings Plans We sponsor various defined contribution savings plans which allow participants to make voluntary contributions by salary deduction. Such plans cover substantially all of our domestic, nonunion employees in the U.S. and are qualified under Section 401(k) of the U.S. Internal Revenue Code. Similar plans outside the U.S. cover various groups of employees of our international subsidiaries and affiliates. Several of these plans allow the Company to match, on a voluntary basis, a portion of the employee contributions. The following table presents the Company’s contributions to these savings plans for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):
September 26, 2025 |  | September 27, 2024 |  | September 29, 2023
$ | 169,610 |  |  | $ | 169,727 |  |  | $ | 147,288 |
Deferred Compensation Plans Our non-qualified deferred compensation programs provide benefits payable to directors, officers, and certain key employees or their designated beneficiaries at specified future dates, upon retirement, or death. The plans are unfunded; therefore, benefits are paid from the general assets of the Company. Participants' cash deferrals earn a return based on the participants' selection of investments in several hypothetical investment options. Participants are also able to defer stock based compensation in the plans, which must remain invested in Company stock and are distributed in shares of Jacobs common stock. Since no investment diversification is permitted, changes in the fair value of Jacobs' common stock are not recognized. For the deferred compensation held in company stock, the number of shares needed to settle the liability is included in the denominator in both the basic and diluted earnings per share calculations. The following table presents the amount charged to (income)/expense for the Company’s deferred compensation plans for the years ended September 26, 2025, September 27, 2024 and September 29, 2023 (in thousands):
September 26, 2025 |  | September 27, 2024 |  | September 29, 2023
$ | 3,631 |  |  | $ | (1,471) |  |  | $ | 4,679 |

Deferred compensation arrangement investments are comprised primarily of the cash surrender value of life insurance policies and pooled-investment funds. The fair value of the pooled investment funds is derived using Level 2 inputs.
