Postemployment Benefits [Abstract]
Compensation and Employee Benefit Plans	EMPLOYEE BENEFIT PLANSWe established a defined contribution savings plan under Section 401(k) of the Internal Revenue Code of 1986, as amended on October 1, 2009 (“401(k) Plan”). The 401(k) Plan follows a calendar year, covers substantially all U.S. employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pretax basis, subject to legal limitations. Our contributions to the 401(k) Plan may be made at the discretion of the board of directors. During the fiscal year ended October 2, 2020, we contributed $2.3 million to our 401(k) Plan for calendar year 2019. During the fiscal year ended September 27, 2019, we contributed $2.6 million to our 401(k) Plan for calendar year 2018. Our employees located in foreign jurisdictions meeting minimum age and service requirements participate in defined contribution plans whereby participants may defer a portion of their annual compensation on a pretax basis, subject to legal limitations. Company contributions to these plans are discretionary and vary per region. We expensed contributions of $1.0 million, $1.1 million and $1.2 million for fiscal years 2020, 2019 and 2018, respectively.
