The information I have received from Nordnet Sweden is that the shares will later be moved from ISK or KF to a “normal” stock account. No forced selling will take place.
I contacted avanza today and the information i got is that they will NOT sell, they will move it to a regular account and you will not be able to trade your shares on the otc. But they will NOT sell, you can then transfer your shares to Nordnet or another broker if you want to sell.
