Hi ANATH,
The replies you refer to are for reporting funds and non reporting funds which have different tax status.
The main effect for UK investors who have invested in non-reporting funds, as opposed to reporting funds, is that on disposal of their interests they will be liable to tax on any gain arising as if it were income (that is, an offshore income gain, or ‘OIG’) instead of as a capital gain.
There are certain exceptions to this - see
IFM13400 onwards.
Thank you.
