RETIREMENT AND OTHER EMPLOYEE BENEFIT PROGRAMS

RETIREMENT AND OTHER EMPLOYEE BENEFIT PROGRAMS

Defined Contribution Plans:

The Company has a 401(k) defined contribution retirement savings plan (the “Plan”) covering substantially all domestic employees. Each participant may elect to defer a portion of his or her compensation subject to certain limitations. The Company may contribute up to 50% of compensation contributed to the Plan by each employee up to a maximum of $3,000 per annum. During the years ended December 31, 2022, 2021, and 2020, the Company's contributions were $10.0 million, $9.2 million and $8.7 million, respectively.

The Company also has several foreign defined contribution plans, which require the Company to contribute a percentage of the participating employee’s salary according to local regulations. During the years ended December 31, 2022, 2021, and 2020, the Company's total contributions were $4.4 million, $4.7 million and $4.6 million, respectively.

Multiemployer Defined Benefit Pension Plans:

The Company participates in two trustee-managed multiemployer defined benefit pension plans (“Multiemployer Pension Plans”) for employees who are covered by collective bargaining agreements. The risks of participating in these Multiemployer Pension Plans are different from single-employer plans in that (i) assets contributed to the Multiemployer Pension 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 Multiemployer Pension Plans, the unfunded obligations of the Multiemployer Pension Plan may be required to be assumed by the remaining participating employers and (iii) if the Company chooses to stop participating in any of its Multiemployer Pension Plans or if any event should significantly reduce or eliminate the need to participate (such as employee layoffs or closure of a location), the Company may be required to pay those Multiemployer Pension Plans a withdrawal amount based on the underfunded status of the Multiemployer Pension Plan. Based upon the most recent information available, one of the Multiemployer Pension Plans the Company participates in is in “critical” status due to an accumulated funding deficiency and has adopted a rehabilitation plan to address the funding deficiency position.

The following table outlines the Company’s participation in Multiemployer Pension Plans:

			Pension Protection Act Zone Status (1), (3)		FIP/RP Status (2)	Company Contributions (4) (in millions)				Expiration Date of Collective Bargaining Agreements
	Plan Employer ID Number	Plan #	2022	2021		2022		2021
Pension Plan Private Sanitation Union, Local 813 IBT	13-1975659	1	Red/ Critical	Red/ Critical	Implemented	$	0.6	$	0.6	various dates
Nurses And Local 813 IBT Retirement Plan	13-3628926	1	Green	Green	N/A	$	0.1	$	—	various dates

(1)Zone status is defined by the Department of Labor and the Pension Protection Act and represents the level at which the plan is funded. Plans in the red zone are less than 65% funded, while plans in the green zone are at least 80% funded. Status is based on information received from the Multiemployer Pension Plans and is certified by a Multiemployer Pension Plan actuary.

(2)The “FIP/RP Status” column indicates Multiemployer Pension Plans for which a Funding Improvement Plan (“FIP”) or a Rehabilitation Plan (“RP”) has been implemented or is pending. The most recent Pension Protection Act zone status available in 2022 and 2021, is for the plans’ year-end December 31, 2021.

(3)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, until certain conditions are met. Contributing employers, however, may eliminate the surcharge by entering into a collective bargaining agreement that meets the requirements of the applicable FIP or RP.

(4)The Company was listed in the Form 5500 for the Pension Plan Private Sanitation Union Local 813 IBT as individually significant for contributing more than 5% of total contributions to such plan during the plan years ended December 31, 2021. At the date these financial statements were issued, Forms 5500 were not available for the Multiemployer Pension Plans for the year ended December 31, 2022.
