For reference, as I figured this out with the assistance of Sharesight support.
Say you have a notional distribution of £100, of which £30 is an equalisation and £70 is an accumulation distribution, you will need the following:
- Entry in the ‘All distributions’ section, of £70.
- Entry in the ‘Trades & adjustments’ section of a ‘Capital call’ of £100
- Entry in the ‘Trades & adjustments’ section of a ‘Return of capital’ of £30
In this way your cost base, dividends and total return figures will be correct.
