Which institutions are already using FICO ’08, and how much will the new version lower my score?

The "selling point" of FICO '08 is broad based. The Fair Isaac Company said, "The strongest improvements in risk prediction over current FICO scores are achieved in key consumer segments such as those opening new accounts or having prior derogatory information. In addition, this newest generation of FICO scores includes refinements to help lenders better evaluate consumers who are comparatively new to credit." Fine, but what does that mean?

A webinar put on by the company in September of 2009 allowed for some interesting interchange. We were told that people with very high scores would be unaffected, but those in the lower ranges could expect to see their scores drop by as much as 10 to 30 points. That statistic is NOT published anywhere, lest you go looking for it. The new version would also identify authorized user accounts that had been set up for the sole purpose of creating the appearance of a long-established trade line. We were told that collection accounts less than $100 would not affect the score, nor would an isolated late payment if the consumer had an otherwise stellar payment history.
