At the discretion of the Retirement Savings Plan Committee, the Plan matches 50% of the first 6% of compensation as defined that is contributed to the Plan, with a maximum matching contribution of 3% of compensation. In addition, the Plan provides for non-elective non-discretionary contributions on behalf of participants who have completed one year of service equal to 3% of the eligible participant's compensation, as defined. Participants who are eligible to make contributions and who have or will attain age 50 before the end of the Plan year are eligible to make catch-up contributions in accordance with, and subject to, the limitations of the IRC. No Company matching contributions are made with respect to catch-up contributions. Participant Accounts Each participant’s account is credited or deducted with the participant’s contribution and any applicable direct expenses and allocation of the Company’s contributions and any Plan earnings and losses. Allocations are based on participant earnings, account balances, or specific participation transactions, as defined.

Interest rates on outstanding participant notes receivable as of December 31, 2025 ranged from 4.25% to 9.50%. Principal and interest are paid ratably through periodic payroll deductions.

In addition, a participant may elect to take an in-service distribution from their rollover account prior to reaching age 59 ½, and from all accounts upon reaching age 59 ½.
