The SUNE shares that you own now will be automatically be converted to SUNEQ (or some ticker with a Q).
If you still own SUNEQ shares when they emerge from Ch11, then those SUNEQ shares will be worthless. They will begin selling new shares with a new symbol. You will have plenty of time to sell your SUNEQ shares. If you own shares of SUNEQ, I suggest that you do not panic, especially when this drops below 20 cents or less.
