Alert and score decrease. Why?

[CP901]

Why would this change on my credit report result in a 13 point decrease? My husband and I both had this alert show up today and a decrease in score.

The account has been paid in full for 2 or 3 months and has never been late.  Thanks!!

Its because Capital One sold the card to Citi. Citi should be listing a new account at some point that they are supposed to report with the original open date.   That could be a mixed bag as well depening on the age of the card and your AAOA.  The drop could have been due to utilization because it lowered your over all available credit.

Makes sense. I'll watch for it. Thanks.
