if they wanted to borrow the shares to short, and believe that the shares will drop substantially (i.e. more 6%), then they probably won't mind paying the interest. They obviously would be looking for a quick play out of this, as to minimize interest payments. This assumes they are going to do the shorting themselves ofcourse.
that's one scenario anyway.
oth, a long arguement might be that maybe they are indeed desparate to cover and don't mind paying more to do so. i highly doubt this however...
