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 27, 2019, September 28, 2018 and September 29, 2017 (in thousands):
September 27, 2019 |  | September 28, 2018 |  | September 29, 2017

Deferred Compensation Plans Our Executive Security Plan, Executive Deferral Plans, Directors Deferral Plan, legacy CH2M Supplemental Executive Retirement and Retention Plan and legacy CH2M Deferred Compensation Plan are non-qualified deferred compensation programs that 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 expense for the Company’s deferred compensation plans for the years ended September 27, 2019, September 28, 2018 and September 29, 2017 (in thousands):
September 27, 2019 |  | September 28, 2018 |  | September 29, 2017
