Frequently Asked Questions

I mail one check with funds for multiple departments. Which address do I use?

For fastest processing, send separate checks. If that's not feasible:

  • Non-ERISA retirement + Flexible Benefits funding → Non-ERISA Retirement address
  • Non-ERISA retirement funding + admin fees → Non-ERISA Retirement address
  • Flexible Benefits funding + admin fees → Flexible Benefits Department address

My bank requires a business address for wire transfers. Which do I use?

Use the address corresponding to the type of funding you are sending.
