Employee 401(k) Profit Sharing Plans

20. EMPLOYEE 401(k) PROFIT SHARING PLANS:

Employees are eligible to participate in our 401(k) Profit Sharing Plan (the “Plan”) following their 90-day introductory period starting either April 1 or October 1, provided that they are 21 years of age. Under the Plan, we matched 50% of participants’ contributions, up to a maximum of 6% of each participant’s compensation. We contributed, under the Plan, or pursuant to previous similar plans, approximately $2.7 million, $5.0 million, and $6.1 million for the fiscal years ended September 30, 2020, 2021 and 2022, respectively.
