TAS/EDE relative values, page-858

I posted this on the EDE Board;
"EDE up TAS down. At close of trade the ratio is now 1.45833 to 1.
The last TAS announcement said;

"Based on the last traded prices on the ASX of EDE ($0.15) and EDEO ($0.12) on 8 January 2018,
this investment had a market value of $86 million, which is equivalent to 21.3 cents for every​

currently issued TAS share."
So ????  According to the TAS announcement TAS should be worth 24.85c. Or based on the TAS price of 12c then EDE should only be around 10c.

Be nice for GS to explain why it is what it is. I have put out my ideas for it in the past but for the relative value to blow out to this extreme is way out of my reasoning."
