Just wanted to start a thread around Demerger tax implication (CGT). As LeoCo (LLL) will soon list separately on ASX.

I am not a tax professional, so wondering what's gonna happen, and how did it go for other company that did the same in the past?

Say someone bought FFX at 60c for 100,000 shares (for ease of calculation), at 01 Sep 2021 and held them. Fast forward to, say, March 15 2022, and LLL is listed and this person received 1 LLL for 5 shares held in FFX (and elect not to buy more LLL in SPP for simplicity), so now holding 100,000 FFX + 20,000 LLL (share prices at close are, say, FFX: 70c / LLL: $1.10 at 15 March 2022 for ease of calculation)

Then how do you calculate capital gain for FFX (post-demerger) and LLL, if this person decide to sell 70,000 FFX and 10,000 LLL for some cash, at close prices above? What cost base should we attribute to these 2 transactions, each of to FFX and LLL, as this person only paid for FFX 6 month ago.

Could anyone help me on this?

Thanks!
