We have traditionally had a turnover rate of about 10%, so that's the reason we've set it at 90%, and I think 10% is kind of normal. We need to have that kind of attrition. I think it's to be expected, either with retirements or simply to kind of regenerate our population.
We were a little concerned at certain levels. We were losing people at certain levels, so there needs to be, probably.... The 86% in and of itself is probably not problematic; it depends where the attrition is occurring.
