As of June 10, 2024, the Plan transitioned to a new recordkeeper and Trustee (Fidelity). The investment options available in the 401(k) Plan did not change as part of the transition. Participant investments as of market close on June 7, 2024, transferred to the same investments at Fidelity (called a reregistration, or in-kind transfer) and remained invested in the market during the transition.

Certain higher-paid participants may be limited to a lesser percentage. New employees are auto-enrolled into the Plan with pre-tax contributions of 6% of their compensation.

The automatic enrollment provision does not apply to Roth 401(k) contributions. Participants can opt out of the automatic increase program.

The Company may also make additional discretionary contributions, if authorized by its Board of Directors; however, no such discretionary contributions were made for the years presented.
