Retirement Benefits [Abstract]
Defined Contribution Plans	Defined Contribution Plans The Company sponsors a 401(k) plan which covers substantially all U.S. employees meeting certain employment requirements. Participants may contribute up to 50% of their eligible salary and up to 100% of the cash portion of their year-end bonus, as defined by the plan and subject to Internal Revenue Code limitations, each year to the plan. The Company makes a matching contribution equal to 85% of eligible compensation contributed by participants. Certain of the Company’s non-U.S. subsidiaries also sponsor defined contribution plans primarily for the purpose of providing deferred compensation incentives for employees and to comply with local regulatory requirements. The total expenses recognized for defined contribution plans were $84.9 million, $81.4 million and $59.2 million for fiscal years 2022, 2021 and 2020.
