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 28, 2018, September 29, 2017 and September 30, 2016 (in thousands):

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.
