During 2025, forfeitures were used to pay expenses of the Plan. Payment of Benefits - Upon termination of service, a participant may elect to receive either a lump-sum distribution or monthly or yearly payments equal to the value of their account.

All withdrawal payments are made by Fidelity Management Trust Company (the “Trustee” or “Fidelity”).
