I CSAV's put up for auction CSA. Mostly you but can not be returned.
They do it because they are very long inactive branch and you can see that, at least not yet interested in SFI continue.
Thus, it is possible hope that soon the SFI fall out, but they can perhaps after a year or longer continue.
In geneologii then they do not take up unnecessary space. The question is when you decide to do this?
