From my experience, JCP does report AU's. Case in point: My husband added me as an AU on his JCP card. However, his ultilization was way high. Like 4,500 of a 5,000 limit. So I called the bureaus and asked to be removed. Although his payment history is excellent and his credit limit fairly high, my FICO went UP when I took myself off. I suppose it was because of the high ulitization.
