Most stocks drop an average of 15% after the tender. SVU may go to $3.40 or lower after the tender.
If you bought recently, say 100k at an average of $3.60 and you tender all your shares and assume 50% or 50 k accepted at $4 and 50% returns to you and you have to chance to get rid of remaining at $3.40 you still will make some money but with high risk.
If your average is higher then forget it. Sell now and be happy.
