It is your right to distribute your bonds. You can choose to take out your money to buy bonds, or you can choose to give up. But it can't be sold directly, and it can't be sold until the bond is listed.

Those who robbed the June 1 call right will be miserable, losing 6% today. Since there is a share option, you'd better buy bonds. After all, bonds can be sold at a premium when they are listed.
