Treatment for unrealized capital gain/loss

For unrealized capital gain/loss on the various types of securities (trading securities, available for sale securities, held to maturity securities), do we have to know them for L1? I don’t think it was covered in the CFAI text, but I came across a question on Schweser qbank on this topic, specifically, it was on unrealized gain for available for sale securities, and the question was how to account for the tax liability for such gain… I recall someone saying these are covered in L2, can someone please confirm this?

These were covered in L2 only when I took LI and LII in '05 and '06. I would definitely check the LOS. If it’s not in there then don’t worry about it.

Thanks TMurf, I checked all the relevant LOSs, couldn’t find anything specific to those
