Why does my AMEX Platinum show up as a utilization of my total credit?

[Anonymous]

When I look at my credit report, my Amex Platinum shows up as being part of my credit utilization!  Given that I have no limit on my AMEX, how can they calculate what my total credit limit is and then how can it be used to calculate my % utilization?

Any ideas?  Thanks.

Out of curiosity, is it TU on Myfico? My zync does that too, only on TU on here

This should only happen with the TU 98 scoring model, the TU score sold here. Is your Platinum card reporting as an "open" account with a "high balance" on EQ?
