Again in general, I think what we found was the 2% error rate in overpayments and underpayments was supported by the work that had been done by the department. Again, understanding that we have some concerns about the way they selected their samples, but based on the work they did on the roughly 1,000 files they looked at, it seemed to support the conclusion that the error rate would not be more than 2%.
However, we had some concerns with the fact that the work they were doing was not giving confidence that the number of files with incomplete data was 5% or less. That's where we feel they need to do some more work.
