Bosch buyback single share scenario

I have just 1 share of Bosch company. When they open buyback will my eligible share be zero or one? Can someone clarify? I understand acceptance ratio concept but minimum eligible rights to buyback is how much ? 0 or 1?

even if you hold one share you are eligible to participate in buyback .

In the letter of offer it would be stated as 0 shares accepted . But there is clause saying that incase of fractional shares you are eligible for 1 share.

In summary , if you have only one share that one share would be accepted for buyback hence making 100%. Hence good chance to make around more than 14% by buying today at 18300 and selling selling at 21000 on investment of 18300.
