Tax Implications of Selling LLL Shares, page-21

Forgive me for digging this up again! I'm trying to figure this out but haven't yet.

Ultimately, if I bought shares in FFX more than 12 months ago, what's the tax implications for selling now (+12 months) for

• FFX
• LLL

I've already sold some on both sides of the fence but trying to figure out what the hell happens in the tax return. I also use Sharesight, which currently seems to show any gains/losses on FFX against my original purchase price for FFX sells... but I don't know how it works if I sold any of my LLL

Thanks very much
