TLL - TIL Logisitics Group [was BIL - Bethunes Investments]

[Jerry]

OK. Newby question...
on 26/10/17 there's a trading halt on BIL. TLL share price around the $2.54 mark. BUT suddenly the shares on TLL are around the $5 mark.
I get doled out my two pennorth of shares in TLL (because I hold Bethunes). I then discover I have paid $5.07 for the TLL.
On 7/12/17 Trading halt lifted and the shares go back down about $2.75

How does that work? Obviously it works to someone else's advantage, not the Bethunes shareholders! :-(
