Postemployment Benefits [Abstract] |
Employee benefit plans | Employee Benefit Plans 401(k) Retirement Plan The Company has a 401(k) retirement plan covering substantially all of its employees. Company contributions to the 401(k) retirement plan were $5.0 million, $4.8 million, and $4.5 million for fiscal 2019, 2018, and 2017, respectively. Multiemployer Pension Plans In addition to the Company's 401(k) retirement plan, the Company participates in a number of multiemployer defined benefit pension plans for employees who are covered by collective bargaining agreements. The Company is not aware of any significant future obligations or funding requirements related to these plans other than the ongoing contributions that are paid as hours are worked by plan participants. However, the risks of participating in multiemployer pension plans are different from those in single-employer plans in that (i) assets contributed to the plan by one employer may be used to provide benefits to employees or former employees of other participating employers; (ii) if a participating employer stops contributing to the plan, the unfunded obligations of the plan may be required to be assumed by the remaining participating employers and (iii) if the Company chooses to stop participating in a multiemployer pension plan, it may be required to pay the plan a withdrawal amount based on the underfunded status of the plan. The following table outlines the Company's participation in multiemployer pension plans considered to be individually significant (dollar amounts in thousands):

(1) | The most recent Pension Protection Act zone status available for fiscal 2019 and 2018 is for the plan’s year-end as of December 31, 2017 and 2016, respectively. The zone status is based on information that the Company received from the plan and is certified by the plan’s actuary. A plan is generally classified in critical status if a funding deficiency is projected within four years or five years, depending on other criteria. A plan in critical status is classified in critical and declining status if it is projected to become insolvent in the next 15 or 20 years, depending on other criteria. A plan is classified in endangered status if its funded percentage is less than 80% or a funding deficiency is projected within seven years. If the plan satisfies both of these triggers, it is classified in seriously endangered status. A plan not classified in any other status is classified in the green zone. As of the date the financial statements were issued, Form 5500, which is filed by employee benefit plans to satisfy annual reporting requirements under the Employee Retirement Income Security Act and under the Internal Revenue Code, was not available for the plan year ended in 2018.
(2) | In April 2019, the Boilermaker-Blacksmith National Pension Trust disclosed that the plan will be classified in critical status commencing for the plan year beginning January 1, 2019 because there is a projected funding deficiency in the plan year ending December 31, 2028.
(3) | The “FIP/RP Status” column indicates plans for which a Funding Improvement Plan (“FIP”) or a Rehabilitation Plan (“RP”) has been implemented.
(4) | For the multiemployer pension plan considered to be individually significant, the Company was not listed in the Form 5500 as providing more than 5% of the total contributions for plan years ending December 31, 2017 and 2016.
(5) | A multiemployer pension plan that has been certified as endangered, seriously endangered or critical may begin to levy a statutory surcharge on contribution rates. Once authorized, the surcharge is at the rate of 5% for the first 12 months and 10% for any periods thereafter. Contributing employers, however, may eliminate the surcharge by entering into a collective bargaining agreement that meets the requirements of the applicable FIP or RP.
