IPX Fidelity vs Vanguard Proper in 403(b) Forum Posted May 30 · Report reply Hi. The $36 OMNI fee is what my district pays OMNI per participant. My memory is foggy on this whole situation, but I do remember talking to and emailing with a representative from IPX. I also uses 403Bcompare.com. That is where I would have gotten my information from. The representative I spoke with and emailed with was Rick Moser <firstname.lastname@example.org. I would email him. He was very responsive and answered all of my questions. I ended up going with Vanguard direct and have been happy minus some issues with how quickly they processed my transfer of funds from Aspire. Please let me know if you have any other questions.
